You Shouldn’t Be Scared of Information – Figure Out How to Apply It

The perks linked to buying the necessary technology training that will permit the vital players in your business to manage to make the most of everything that the vast amount of data available to these people provides is certainly incalculable. Maybe Wall Street’s Gordon Gekko said it best as he manufactured the actual point that info is essentially the most valuable commodity of all of them. Together with admission to huge amounts of big data and also the expertise instinctive to being able to view, parsing, deciphering and also making use of it here as required, you will find a feeling by which the holder and also manipulator has almost god-like skills, or certainly, the actual possibility to possess them.

Big data employed rightly supplies folks, organizations, industries and also authorities the ability to create forecasts with regards to the course and also developments regarding marketplaces, financial systems, sales and people. It enables a person to determine where by money is becoming made, misplaced and where by the potential to produce or even lose it lies. It determines the well-being of a population and also the probability of its continuing as it is or even altering in one method or any other. With the right facts at someone’s convenience, one will no longer have any need to theorize, but they can, alternatively, realize, think as well as plan to be able to make use of the insights acquired. All that’s needed is definitely the knowledge of making use of exactly what one already has got.

Ensure You Are Able To Get Into Your Apartment

A lot of apartments are making use of special keys to avoid any troubles when somebody moves in or out. A key fob could be changed while not having to change the locks inside the entranceway, making it less difficult for the management to swap the keys whenever somebody moves in or perhaps out as well as to ensure the apartment is going to be safeguarded. Despite the fact that this can be extremely helpful, it can have its downsides as well and therefore someone will certainly need to make certain they will realize exactly how to deal with any problems with theirs.

Anytime a person moves into a brand-new apartment, they may wish to determine if it’s possible to clone key fob. Several managers may allow them to clone their own copy to enable them to offer a trustworthy family member or friend one to hold onto just in case they will lose their particular key. Some other managers may not enable the keys to be cloned, meaning they are going to have to speak to management in the event they’ll lose their particular key and therefore cannot get inside of their own apartment. This could make it hard in case they will lose the key anytime the management isn’t available, thus it really is something the individual should inquire about as they may need to ask for a pair of keys from the start in this situation.

The individual can also wish to make sure the key will be changed right before they will move in. Though it may not be allowed for them to make a duplicate key fob independently, it is feasible the prior tenant did and still has a replicate of the key. This implies the last tenant or any individual they might have presented a copy to may be able to go into the apartment at any time they want even after the new tenant moves in. Changing the key can prevent this from occurring and will ensure the tenant will be the only person with a copy of the key.

In case you are moving to a new apartment which uses these keys, it is crucial that you fully grasp more regarding them and also about exactly how as well as precisely why you could need to have a duplicate apartment key fob. Find out more about one company that can enable you to make a new one if perhaps you’ll need to have it or help you make sure your apartment will be secure. You may wish to get in touch with them today to understand much more.

SD-WAN – AKA A Three Stranded Cord Is Not Easily Broken

Many of us have heard the adage: “A Three Stranded Cord is Not Easily Broken.” Inherently, we understand that this is true. We see this demonstrated for example when we purchase rope: lots of strings intertwined. Over the years as the cords weaken, one may break but the rope still holds. With this basic explanation, you now understand SD-WAN.

Now let me explain a little further.

Whenever a new technology solution arrives on the scene it takes a while before its widespread adoption. Part of the reason is that new terms are created and blended with our existing vocabulary creating confusion. SD-WAN is a new technology born out of a recognition that one of the major expenses for many organizations is their bandwidth. Over the years numerous technologies have been introduced to reduce these costs:

Voice over Frame-Relay
WAN Optimizers

Just to name a few.

The carriers have also been trying to stretch and maximize their investments. For most of us the network has become a utility. We expect an always on network and use it constantly. Just look around, the proliferation of hand held mobile devices with a plethora of applications that allow non-stop communication, entertainment, and access to information (Maps, Google, Starbucks) has created a demand for bandwidth that is frankly challenging to meet. Each of the respective carriers is adding bandwidth daily. I work with a number of them and Time Warner, AT&T and others are laying fiber all over metropolitan areas. Private companies have cropped up that lay and sell both dark and lit fiber.

We also see that the cellular companies are adding and upgrading cell sites and working to partner with other cellular companies to exchange bandwidth. The appetite for bandwidth is so high that 3rd party companies are building cell sites and selling or renting them to the highest bidder.

Enough said, back to SDN-WAN.

This demand for higher amounts bandwidth is a challenge for most, if not all, organizations. Every CIO is faced with the need to increase the amount of bandwidth, while trying to maintain costs. IT Budgets are consistently flat and 80% of the IT budget is spent just maintaining the status quo. The reality of today is that the network IS a utility and if it goes down, most organizations come to a grinding halt. “All the while, of course, the IT department is expected to deliver value for money by minimizing capital expenditure and operational costs wherever possible.” My focus is the SDN over SPB, and while I seek to build secure, resilient, always on infrastructures that are easy to manage and deploy, eventually we have to leave the premise and traverse the WAN. Whenever I have to extend my network fabric over the WAN I am faced with the reality that the single MPLS pipe they pay for becomes my single point of failure. It doesn’t matter that my SDN network built on SPB has sub second failover, if that WAN link is the only link, my network is down. Those virtual servers and applications are cutoff from the users. I now bring in my carriers and help the customers to create a more resilient WAN.

Enter in SD WAN.

Talari and other companies have developed technologies and algorithms that allow the bonding together of multiple lower costs links from different carriers into a single, higher aggregate bandwidth pipe, that has higher availability and throughput than a traditional more expensive MPLS network. In addition, because we have spread the bandwidth over different medium (cable, fiber, G4, etc), and different companies, the failure of any one link does not bring the network down and is therefore more resilient. So, the adage: A three stranded cord… applies.

There are a number of organizations that are offering SD-WAN, and there are a number of great white papers available for those of you that would like to get a better understanding of what, how, who, etc. Most traditional router/WAN Optimize vendors have begun to develop products in this area, so make sure, when investigating them to do your research. I work with a number of carriers and they are starting to include this as part of their service. They provide multiple connections over different technologies and incorporate the SD-WAN service as a bundle. I suspect that this trend will become common place. It seems like a win-win to me. As with most technologies today, there are hosted and premise offerings and many include firewalls, etc. Make sure if you opt for a hosted solution, that behind the scenes, they are not creating a single point of failure. As always: Caveat Emptor a.k.a. get references.

Take Control Of Your Storage Media Costs With the HPE LTO Ultrium

Prior in the month, we shone the focus on the HPE LTO Ultrium capacity media and the Green Tape Tests that guarantee HPE information cartridges are the most solid recorded media accessible.

Many individuals remarked that they had not seen this data exhibited along these lines some time recently. Be that as it may, some additionally inquired as to whether I could clarify a smidgen more about what this sort of testing means for everyday tape use and unwavering quality generally.

So why does HPE put such a great amount of cash in Green Tape Tests and whatever is left of HPE’s Extreme Testing for capacity media?

This is on account of enhanced media unwavering quality will significantly lessen the expense of your reinforcement and filing system.

Take a gander at the two outlines underneath. They demonstrate the limit got from HPE LTO-7 media versus that of a main rival brand utilizing fresh out of the box new ‘green tape’ cartridges. More than 1,000 cycles, the HPE media conveyed around 6 TB of local limit for every full reinforcement, precisely per the LTO-7 determination. With the non-HPE media, it was an alternate story. One test ended at 500 cycles and the second at 250 cycles because of maintained limit misfortune, well underneath 6 TB.

The Significance Of Blunder Rate

The motivation behind why the limit diminishes is a result of high mistake rate. At the point when a tape is problematic, one pointer of this is the drive needs to make numerous endeavors to effectively compose a square or pieces of information. Each retry utilizes a tiny bit more tape which is clearly a limited asset inside every cartridge. At last, different retries brought on by mistakes confines the measure of tape accessible for putting away new information and diminishes the limit of the cartridge general.

In the diagram above, you can see a reliable loss of limit of between 15-20%. Presently think about that as some of HPE’s Enterprise clients use more than 200,000 cartridges for each year. Would you be able to envision the expense of an extra 30,000 cartridges to recuperate 15% of lost stockpiling potential. On that sort of scale, the expense of lost limit keeps running into millions.

In any case, even in little and moderate sized associations, the shrouded expense of media unwavering quality can be huge. Also, here’s another imperative point. In mechanized situations with numerous tapes being used, it might be hard to survey the effect of poor media unwavering quality. Be that as it may, much the same as low expanded tires can eat into the mileage and expansion the expenses of motoring, so subs standard quality influence your clients’ main concern.

Certifiable Illustrations

How about we expect your information store is 600,000 GB. Contingent upon your information and pressure proportion, you could require 400 LTO-5 tapes to store that measure of substance.

A HPE LTO-5 tape costs $22 and Another Brand costs $20. Altogether, 500 tapes from HPE will cost $8,800 versus $8,000 for the contender.

However, in the event that you are encountering 15% limit misfortune on the non-HPE tape, then as opposed to getting 600,000 GB, you are just accomplishing 510,000 – a deficit of 90,000 GB.

That implies you require an extra 60 information cartridges, costing an extra $1,200, to document every one of your information.

So now, the less solid non-HPE media has fetched you over $400 more than HPE, despite the fact that it’s ticket cost is $2 per tape less expensive.

What’s more, this is even before we figure the extra IT expense of sourcing, purchase and handle the extra tapes, to say nothing of the potential interruption to server farm exercises. Bunch considers flourish on the mind boggling expense of server farm downtime. Whilst we are not discussing lost information in essence here, anything that removes IT staff from all the more requesting, worth included undertakings mission-basic frameworks will undoubtedly have a much higher expense than simply the $400 of media reserve funds. I discovered a few measurements ascertaining the expense of IT efficiency amid a spontaneous server farm blackout as being $42,000. For corporate clients, this is not a paltry thought!


All in all, in this way, poor limit and exchange measurements have genuine outcomes. Diminished limit implies more tapes are expected to reinforcement the same measure of information. That implies more cost. Slower exchange speeds mean longer reinforcements or reinforcement windows being surpassed or broke, pulling in important IT asset to settle the issues. Once more, the extra superfluous expense can be huge and effectively upset any advantages from picking a less expensive tape.

Teaching Through VR Technology

Virtual Reality , VR in short is a very advanced technology, which is an integration of computer science, robotics, instrumentation, multimedia, sensors, optics, 3-D technology, etc. Each technology, which converges to form VR, in itself, is very sophisticated and hi-tech. VR is a powerful user interface technology. This current technology doesn’t even require physical presence of a person. Information is important and this promising technology provides the best way to visualize it, enabling directly interaction for the user.

VR has full-blown applications in industries like automobile and aviation. Its implementations are now being expanded to fields like education and medicine. In education, Mutual Telexistence (convergence of VR and robotics), Virtual Rooms and Distributed VR have emerged. In medicine, very advanced softwares have been developed to treat growing number of painful procedures. Some of the examples include:

a. Wound care of burn patients

b. Endoscopic therapy after Single Event Multilevel Surgery (SEMLS) for cerebral palsy

c. Dental pain and anxiety

d. Pain/anxiety during injections

e. Overcome phobias like spider phobias

f. Treat various anxiety disorders like Post-traumatic Stress Disorder (PTSD)

g. In artificial limb development

Virtual Environments (VE) for education have been discussed in various ways. While advanced multi-user educational VEs are still a speculation, simpler VEs based on standard technologies have been in existence for some time.

For distance education purposes, distributed VR is useful. Virtual Reality system can be networked to support multiple-user immersion environments joined over long distances. The sites implementing VR technology must be networked using low band modem-to-modem over telephone lines, the Internet, and high bandwidth telecommunications. The emergence of the Virtual Reality Modeling Language (VRML) as a standard method of modeling virtual reality objects and worlds coupled with the wide spread deployment of WWW browsers that support VRML allows the creation of such distributed virtual environments, which can be accessed through Internet. This paves the way for participation of more geographically dispersed users in multi-user virtual reality interface systems.

Applications of VR

The fields in which VR has been implemented are summarized below-

Education and conferencing.

Civilian and military training simulators.

Business and scientific visualization.

Architecture, design, prototyping (Research and Industry).

Art and leisure.

Surgery and rehabilitation.

Telexistence, tele-immersion and Immersive 3D virtual environments (IVR).

SnowWorld, SpiderWorld, ChocolateWorld, SuperSnowWorld.

VR in Education

Virtual Reality technology offers educators a truly new and innovative way to teach and engage students. It is a cutting-edge technology that allows students to step through the computer screen into a 3D interactive environment. Using a special headset and glove, it places students inside of a simulated virtual environment that looks and feels like the real world. Integrating virtual reality into everyday learning has revolutionized teaching and learning processes.

A helpful analogy to better understand the nature of the virtual environment is that of a student exploring a forest for the first time. A student will best learn about the forest not from reading about it or listening to someone talk about it, but by walking into it – becoming a part of it. The student is free to explore the forest any way he/she likes. The biology class where students are learning cell structure is supplemented by a trip to the Virtual Reality Lab where students enter and explore a human cell. Discovery and experience become the best teacher.

Virtual reality is created by an impressive, exciting technology that engages the student. It draws its power from three principles: visual, experiential, and self-directed learning, the most effective ways to teach students. Virtual reality allows students to be fully involved in their education, instead of merely passive observers, focusing first and foremost on the learning needs of students. The age-old problem educators face is how to better involve students in their studies. Traditional teaching methods have sometimes not been effective in the goal of seizing students attention, relegating students to a passive role in the classroom.

Understanding virtual reality-based learning means understanding the shift from text-based education to multi-sensory, experiential learning. Virtual reality copies the way people have always learned – by interacting with the world. It allows hands-on activities to facilitate active learning.

I hear and I forget. I see and I understand. I do and I remember , said Confucius, the wise Chinese Philosopher. Thus, Learning is most effective when it is an active discovery process and realistic learning is more effective as a learning device. VR is learning without boundaries.


Virtual Reality can bring simulation-based learning environments closer to real-life experience. Instead of watching the simulated world through a desktop window, students are immersed in a 3D computer simulation of their work environment, where they can improve their skills through practice on realistic tasks. VR simulation environments are essentially valuable in domains where real life training is expensive or hazardous such as surgery, air combat and control of complex equipment. In addition using networked virtual reality systems, multiple students (possible at different work sites) can learn to perform collaborative or competitive tasks together.

Immersive virtual environments also allow the computer tutor to inhabit the virtual world with the student. To explore the use of intelligent tutoring systems in virtual reality, a pedagogical agent , Steve (Soar Training Expert for Virtual Environments) has been developed which physically collaborates with students, enabling new types of interaction.

Steve s Capabilities

Each student s interface to the virtual world is provided by special-purpose hardware and Lockheed Martin s Vista Viewer software. Students get a 3D immersive view of the world through a head-mounted display (HMD). Vista uses data from a position and orientation sensor on the HMD to update the student s view as they move around. Students interact with the virtual world using a 3D mouse or data gloves. Sensors on the mouse and gloves keep track of the student s hands, and Vista software sends out messages when the student touches virtual objects. These messages are received and handled by the RIDES software which controls the behaviour of the virtual world.

Steve requires two capabilities Steve must be able to demonstrate and explain tasks, and he must be able to monitor students performing tasks, providing assistance when needed. When demonstrating, Steve performs and explains each step of the task. Steve is currently represented by a head and a hand that can manipulate and point at objects.

Steve inhabits the virtual world along with students. To provide a collaborative style of interaction with the student, Steve can gracefully shift between demonstrating a task and monitoring the student s performance of the task. During Steve s demonstrations, the student can interrupt and ask to finish the task, in which case Steve shifts to monitoring. When monitoring a student, the student can always ask Steve to demonstrate a recommended action. Thus, VR supports a natural and flexible collaboration between student and tutor.

Distributed VR and VRML

The idea behind distributed VR is very simple; a simulated world runs not on one computer system, but on several. The computers are connected over a network (possibly the global Internet) and people using those computers are able to interact in real time, sharing the same virtual world. In theory, people may be stationed anywhere in world at different locations, all interacting in a meaningful way in VR. There may be a number of obstacles in establishing such type of an environment, like limited-bandwidth links, latency in delivery of update information and heterogeneous platforms.

The environment in which a distributed VR user is immersed is three-dimensional to the eye and ear. Moving in the environment changes the user s visual and auditory perspective. Unlike a video conferencing system (where an attendee s screen shows other attendees in their own videoconferencing rooms), distributed VR users assemble in a virtual world – they are all seen, for example, seated together around a conference table in one room, or walking together in a virtual building. Every user of a distributed VR appears in the computer environment as an avatar – either a customized graphical representation, a video of the user, or some combination of both – which he or she controls. The user, besides interacting with one another, also deals with one or more computer simulations.

This idea of distributed VR can possibly be implemented using the Virtual Reality Modeling Language (VRML) that aims to aid Internet with 3D spaces. These 3D spaces in VRML are known as worlds. These worlds can be environments or single objects with the file suffix as.wrl. VRML defines a set of objects and functions for modeling simple 3D graphics. These are known as nodes, which are arranged in hierarchies called scene graphs. There is a top-down arrangement in which nodes that are described earlier in a scene affect later ones, but this can be limited by the use of separator nodes. A VRML file is an ASCII file which is interpreted by the browser and converted into a 3D display of the described world. VRML is designed to fit into the existing infrastructure of the Internet and the WWW. It uses existing standards wherever possible, even if those standards have some shortcomings when used with VRML.

In one of the versions of VRML, also known as Moving Worlds, either object in the world can act and react to each other under program control, or they can respond to the user s actions in some way. The features that Moving Worlds currently include are:

I. International character sets for text can be displayed using UTF-8 encoding

ii. A set of new nodes has been added to increase the realism in models that are intended to represent the outdoor world around

iii. Sound generating nodes will also enhance the sense of realism

iv. New sensor nodes will set off certain events when one enters specific areas, or click on certain objects. So, for example, as the viewer approaches an object it can be triggered to start some action or make a noise

v. Collision detection ensures that objects can act as if solid. That is, the user, will not go through walls and floors

vi. Script nodes allow for the animation of objects in the world and the interaction of the world with other applications, for example databases

vii. Multi-user environments. There are many approaches to creating multi-user worlds, and the Moving Worlds aims to provide the functionality required for these, but without dictating which approach is to be used

Virtual Environment based on distributed VR

All the concepts of VR technology highlighted above can be combined in an effective manner to create a virtual environment, just like Steve s room on top of a network. Concept can be implemented on an intranet; and using VRML as the remedial technology along with the existing standards for Internet and World Wide Web it can be further extended to operate in a globalized environment like Internet. VRML produces a hyperspace (or a world), a 3-dimensional space that appears on the display screen. Users can figuratively move within this space by pressing keys to turn left, right, up or down, or go forwards or backwards. The images on the screen will change to create a feel of actual movement through a real space.

The user must access the remote VR server and select the service they require. The remote server then downloads the necessary executable code into the local server from where the student can interact with the virtual environment. It is envisaged that the future educational establishments will want to make their VR based educational programmes available to others. Anyone with appropriate hardware will be able to access these systems for a subscription fee. The main advantage of this approach is that organizations will be able to access appropriate VR based educational material without having to develop material themselves. It is highly likely that it will be possible to gain access to a very wide variety of educational material in this manner. However, there are a number of issues such as copyright and how much capability will be required in the local system.


Within the higher education community there has been an increase in the use of information technology such as multi-media with considerable success. Multi-media based systems provide the student with a very rich source of educational material in a form that makes learning exciting. VR has extremely wide application across a whole range of disciplines and the enabling technology has reached a sufficient level of maturity for it to be seriously applied to education, training and research in higher education. The costs associated with a VR system have been prohibitive for educational establishments (this is still true for fully immersive VR systems) but recent technological developments in computer hardware and software now make it feasible to look at VR as an important aid.

Though VR technology proves to be excellent in any field, yet it is not very popular. The reason being that fully immersive VR setup is still very expensive. The prohibitive costs and inaccessibility of VR technologies, coupled with issues of usability, educator training, operation and maintenance, present important drawbacks for the educational use of VR making it difficult to incorporate in dwindling educational budgets. In spite of these concerns and objections regarding the appropriateness and educational efficacy of virtual reality, there remain compelling reasons for believing that VR learning environments for students warrant serious investigation and can provide strong tools for learning.

DB Access Through VR Technology


This article will make us well-versed with technological aspects of Virtual Reality and its applications especially in the field of scientific databases and clinical trials. Virtual Reality , VR in short is a computer-generated, multidimensional sensory, artificial environment that users experience via interference tools that enable them to immerse themselves in the new environment, navigate within it and interact with objects and characters inhabiting the environment. This gives the user the impression of being in that world. VR is a way for humans to visualize, manipulate and interact with computers and extremely complex data like scientific databases. This article acquaints the readers that VR provides a uniquely different interface to access scientific database, which is a SANDBOX: Scientists Accessing Necessary Data Based on eXperimentation. This virtual reality tool allows the investigator to collect data from the scientific databases without ever typing in a query. The article describes in detail about scientific DB, need of SANDBOX along with how it works and its implementation in NASA. It also provides an insight into the digital Eye Bank used in clinical trials. The article is concluded with some recommendations on the full-fledged scope of VR in clinical trials along with its usage in the areas of Internal Medicine and Surgery.

Virtual reality:

We are familiar with the movie, Matrix and its series. The concept or, the technology used in this movie is Virtual Reality! British Novelist, Roald Dahl, has rightly said, We make realities out of our dreams and dreams out of our realities. We are the dreamers of the dream. Agent Smith and Neo are fighting with each other in a virtual environment; they have immersed themselves in a computer-generated artificial environment. What does the term virtual means? It means something which is not real; as simple as ABC! According to the American Heritage Dictionary, virtual means, existing in essence or effect though not in actual fact or form . Technology, which converges to form VR, is itself very sophisticated and hi-tech. This promising technology provides the best way to visualize information, enabling direct interaction for the user.

We live in a world whose properties we have come to know well through long familiarity. A display connected to a digital computer gives us a chance to gain familiarity with concepts not realizable in the physical world. It is a looking glass into a mathematical world. The ultimate display is a room within which a computer can control the existence of matter. The cardinal virtue of virtual reality is the ability to give users the sense that they are somewhere else .

Implementations of VR

BMW uses VR to generate various models during car production, Flight simulators are used to train pilots, NASA uses it to train astronauts for space walk, having virtual super-powers in a game may incite people to better behavior in the real world. Participants who were given the power to fly like Superman in virtual reality were more helpful afterward, out of virtual reality. The researchers suggest that embodying a superpower in virtual reality may make players to ‘think like superheroes’ and thus, facilitate subsequent helpful behavior in the real world. Some of the implementations present in various fields are:

Automobile, Aviation and NASA

Education like Mutual Telexistence, Virtual Rooms, Distributed VR, Steve etc

Internal Medicine

Anxiety disorders like PTSD

Artificial limb development,

Wound care of burn patients SnowWorld etc

Phobias SpiderWorld etc

Pain/anxiety during injections

Endoscopic therapy after Single Event Multilevel Surgery (SEMLS) for cerebral palsy

Train surgeons for laparoscopic cholecystectomy

Virtual Superheroes, 30 Jan 2013


Scientific databases store large amounts of information typically collected through experimentation. This information is then made available to investigators from a wide range of disciplines, mostly unfamiliar with databases and their associated query languages. A new interface to scientific databases, the SANDBOX: Scientists Accessing Necessary Data Based On eXperimentation has come. The SANDBOX is a virtual reality tool allowing an investigator to visualize the contents of a scientific database while retrieving data. As the data in these databases was typically collected through experimentation, an investigator can use the SANDBOX to retrieve data from the database by placing virtual instruments into a virtual reenactment of the original experiment in the same way as investigator uses an actual instrument to collect data from nature. These instruments give visual and auditory feedback, allowing the user to browse through the data, setting up and running experiments until they have collected the data they need. The SANDBOX allows users to become immersed in the DB. SANDBOX gives the investigator an environment to work in, rather than just a screen to look at. A prototype of the SANDBOX on a subset of NASA’s FIFE scientific database using the CAVE virtual reality theatre to access climatology theatre has already been implemented.

The CAVE is a projection based virtual reality system. The user enters a 10 foot by 10 foot by 10 foot room (or even 20ft by 20ft by 20ft in NASA) where images are projected onto the three of the walls and the floor. When the user dons a pair of lightweight StereoView LCD shutter glasses, the projected images fill the room and surround the user. The user can move around the room reasonably unencumbered, and can walk around or through the virtual objects in the CAVE. Since they can see their own bodies, users have a true sense of being inside the virtual environment. The user carries a physical three button wand to interact with the virtual objects in the CAVE.

SANDBOX is composed of 3 main components: VR Interface, Preprocessor and Local Memory. The VR Interface is responsible for maintaining the virtual environment. It displays the virtual instruments visually and audibly, and monitors the user s actions within the virtual environment. Based on the user s actions, the VR Interface sends requests to the Preprocessor to obtain the necessary data. Based on the current virtual time the VR Interface displays the appropriate data from the local memory. The Preprocessor is responsible for interfacing with the various components of the scientific DB to quickly retrieve data according to the needs of the VR interface and store it in Local Memory. The Local Memory maintains all the info necessary to support the VR Interface. This includes info on the user, the various tracking devices and the instruments that the user has placed in the virtual environment. The database schema is hidden from the user, while still giving the user access to the data. They deal with familiar concepts and instruments in a more natural environment. They can perform visualization while retrieving data.

User is surrounded by an elevated 3D plane on the floor, a pallet of instruments to choose from the right wall, a calendar to choose date from the left wall and a graph, which is displayed on front wall. All the values are displayed in the form of a graph.

Each scientific DB has its own set of instruments. The instruments on the pallet are 3D and animated. Left column of the instrument pallet has instruments like thermometer, wind sock and water beaker, which is linked to columns in relational DB. Center column of the instrument pallet has instruments like LANDSAT satellite, airplane and helicopter, which is linked to graphic files. Right column of the instrument pallet has instruments like Notepad and camera, which is linked to metadata. The user can pick an instrument off the instrument pallet, carry it over to a site, and place it there. Once the instrument is placed at a site, it begins to operate. The mercury level in the thermometer rises and falls with the temperature. The water level in the beaker rises and falls with the rainfall. The orientation of the wind-sock changes with the direction, and speed of the wind. The user can also hear the instruments. A beaker makes a drip sound when its water level rises. The faster the water level is rising, the louder the drip . The average strength of the wind measured by all the wind-socks is used to generate the whoosh sound the strength of the wind determines the pitch of the whoosh . The average temperature measured by all the thermometers is used to generate a cicada sound the higher the temperature, the louder the cicada . An instrument draws attention to itself when there is a change in the value it is monitoring. A user requiring information about a site (textual meta-data) can place the notepad at a site. A page with the text then appears above it. A user requiring a photograph taken at a site (graphical meta-data) can place the camera at a site. The picture of that site then appears above it. In the actual scientific DB, the user would have to integrate this info manually probably through SQL queries. When the user places virtual instruments into the virtual environment, they convert data and give the user feedback in visual and auditory form. The investigator can use this feedback to add additional instruments to the experiment, move the instruments to other locations, or remove unnecessary instruments. There is a continuous visual representation of the instruments on the pallet, placed at sites, and in the user s hand. The user physically places instruments instead of typing queries and can immediately see the result of an action. This allows a novice user to quickly begin using the system to run experiments. Instruments have their current values displayed graphically, audibly, and numerically.

The user can change the settings on a virtual environment using the menu. They can set the minimum and maximum values displayed by the instrument. They can even turn on or off whether the instrument displays quantitative values overhead, whether its values are shown on graph, and whether the instrument makes sound. Each instrument maintains its own individual settings.

Sequence of Actions to create SANDBOX

  1. Create the space and time mapping functions
  2. Use the existing metadata in the DB to create a familiar environment
  3. Choose the instrument classes, access functions, and filter functions from an existing library, or create them as needed
  4. Create the linkages as needed

The first 2 steps are necessary to setup the virtual environment

After that, instruments can be created and linked to DB as they are needed

Digital Eye Bank

Clinical trials can be time-consuming, expensive and intrusive, but they are also necessary. Thus, University of Tennessee Space Institute in Tullahoma developed an invention that makes clinical trials more efficient by moving them into the virtual world. Digital Eye bank is a computer software eye modeling program. It includes data from people s eyes for researchers to use when testing their inventions. It takes data from eyes of patients and builds it into models from the commercial optics program to be used for researchers virtual clinical trials. The idea of Eye Bank is to use existing clinical data and build in realistic and personalized eye models stored in a ready-to-use tool kit like a group of volunteers, said Chen. Then we can call on any specific eye to test a newly designed optical instrument on the computer and see what kind of performance the design gets. This testing can be done repeatedly without hurting real human subjects.

These days in most of the clinical trials, the types and conditions of eyes that are studied are not as varied as desired because it is difficult and expensive to find the diversity and range of subjects. Hence, it results in uncertainty in the performance of new instruments to detect and diagnose a range of unusual eye conditions. In the virtual world, users can manipulate the eye, such as opening it partially or rotating the pupil. They can also add certain conditions like growing a cataract or, developing a tear duct issue. This allows users to see how well their instrument measures in response to such conditions. For instance, we can predict how one person’s eye can react to LASIK surgery and simulate the day and night vision after the procedure,” said Chen. “Today, it is also not well known on how the long-term outcome of new interventions would be. But in the virtual world, we could induce cataract and dry eye and other aging conditions to predict the possible complicated outcomes and problems.” Eye Bank can also be helpful in medical education like training students on diseased eyes. Though it s currently used for optical research yet researchers see broad applications for this promising technology.


VR has wide application areas and has reached sufficient levels of maturity but its set-up is still expensive. VR can even be useful in detection of safety signals.

Signal is the information about an adverse event. Safety signals warrant further investigations, which include new adverse events that are not currently documented in the product label especially if serious and in rare untreated populations or, maybe an apparent increase in the severity of an adverse event that is already included in the product label or, occurrence of serious adverse events known to be extremely rare in the general population or, previously unrecognized interactions with other medicines, dietary supplements, foods, or medical devices etc.

VR can be used by any of the Statistical teams of pharmaceutical industries. There s full-fledged scope of VR in clinical trials in future: VR on top of Data Warehouse of clinical trial.

Why Technology Should Be Used in the Classroom

We are faced today with the younger generation that uses gadgets are their means of entertainment and source of fun. No matter how we try to do away with it and let our children experience the childhood we had, it has become a fact that we really have to face.

With this, a lot of professionals in the field of education have come to realize that Technology could be a perfect tool for learning. Children as young as 3 or 4 years old are capable of handling these gadgets thus are expected to be knowledgeable in operating one.

However, teachers must be sure that their students would not be so soaked with stressful learning alone but must have time for fun – allowing them to explore their imaginations. Integrating Technology in the classroom would allow these young individuals to develop their technical skills. These skills are all valuable for them to survive their generation.

A specific example to this is the use of iPads. Here are a few of what can be done:

  1. Documentation needs for student research can be made so easy with the camera.
  2. On higher education and when it comes to art or architecture, 3D models can be created with a 3D creator app, linked to a 3D printer.
  3. Find quiz apps online such as those that allow teachers to create flash cards or other types of interesting types of quizzes.
  4. An iPad could be a game show, applications for this are available too.
  5. Get linked online and play a lot of songs in the classroom that would usher to a more fun while learning. This is essential for the younger ones, especially.
  6. Recording a discussion on audio or video would be a lot helpful for students who would love to review before their exams.
  7. Install game apps that are also tools for learning, especially for the younger ones

As the classroom would have digital learning tools, it does not only benefit the students but the teachers as well. As children would engage more in the classroom discussions, teachers will not have hard time getting their attention for each subject. While it’s normal that children do have different interests, certain applications when used can also make a not so interesting subject become interesting and even fun.

There may still be schools today that are not into the use of Technology. Thus, allow me to share a few points below about why you must make use of technology in the classroom:

  1. With the use of such tools and wireless technology, it would be easy for students to determine their future career as they get a fast discovery of their line of interests.
  2. Learning styles can be diverse. Teachers can combine both the traditional way of teaching while using new applications.
  3. Being tech-savvy allows students to be more aware about their environment, not only in their local area but about world events and social awareness.
  4. Students would love to engage in the classroom activities, naturally because they love technology.
  5. Using tools for the day to day discussions allows the students to be excited about what’s next and would be more apt to learn.
  6. Research won’t be an issue at all, as students may have full, yet disciplined access to the internet.
  7. Teachers and students both can have access to digital textbooks and get more updated versions online.
  8. Teachers and students get the chance to discover more learning apps.

There has to be no debating whether to use technology in the classroom or not. Truth of the fact is, we all need technology today and everyone must accept it.

The Best Thermal Cameras for Boating

Serious marine enthusiasts put a lot of thought and energy into finding and purchasing the right gear for their boats. One piece of equipment that should not be overlooked is a high-quality thermal camera. The best thermal cameras use military grade infrared equipment, which has only very recently become available to the general public.

These cameras produce images using infrared radiation. These images are similar to those produced by fixed digital cameras, but they work a little bit differently. They detect differences in heat instead of light. Any amount of difference in the amount of heat being produced will register on the device, providing a much clearer image than the night vision scopes with which they are commonly confused. These produce only hazy green images, whereas thermal cameras are actually quite clear.

One common misconception is that thermal cameras only provide images of objects that are hot. However, everything in the visible spectrum also produces thermal energy. It is not visible to the naked eye, but even ice has a heat signature. High quality thermal cameras can detect differences in these heat signatures down to 0.01 degrees Celsius, displaying them as a shaded black and white image. Because they receive all of their information from heat rather than visible light, they do not work as well during the daytime. They do, however, still function during the day.

What makes this technology so essential on a boat? Since both people and animals have distinct heat signatures, it allows boaters to distinguish between things like crab pots and floating logs, even at night. It can be extremely helpful in emergency circumstances when people fall over the side of the boat, as a person’s head shows up with a distinctly different heat signature than the water around it.

For those who want to take advantage of this technology but do not have the funding for expensive equipment, there are now smartphone applications available that can provide thermal images. Although they are less effective than cameras specifically designed for the purposes of thermal imaging, they are a useful alternative to sometimes prohibitively expensive equipment. The best-developed phone applications blend visual and thermal images to provide more detail.
