(a) Identify two possible ways that the road sensors can detect the passing of
a vehicle. [2 marks]
One way that the road sensors can detect the passing of a vehicle is the video camera on the traffic light, it can take a video of the car passing and record the data in it's video logs and database. Another way they can detect a passing vehicle is through specific monitoring devices that record speed, for example they have radar guns that measure speed and can show how many cars are passing and at which speed.
b)Two ways it could decrease travel journey times is by using sensors to show the speed of people and on major highways because if they did that than less people would use the road in fear of being billed a fine or caught for speeding and by using alternative roads they would not be stuck in traffic which would lead to less people on certain roads and reduce journey time. Another way they can decrease travel journey time is by changing the speed limit and by doing that people would travel at different rates and there would be less congestion on the road.
(c) Explain how the images from the digital speed cameras can be used to send
penalty notices to speeding drivers automatically. [4 marks]
The images from the digital speed cameras can be put into a database and then identify the driver through their license plate number because the database would include all of the license plates with the information of the driver. The penalty would be sent directly to the driver through the mail because the cameras could print out the information of the driver and how fast they were going through hardware like a printer. Another way is by faxing the information and speed from the camera to the user in their listed place of work or business.
(d) This could be abused by authorities because they would not have to do their job any longer because the cameras would do it for them. They would not have to reprimand speeding criminals because it would be done through the the cameras and sent automatically to the driver. The possibilities of this are that the authorities would no longer have initiative to do their job and many more people would receive fines for speeding because they would virtually not be able to speed without getting caught due to these cameras. The advantages of these cameras for the authorities however is that they will be able to catch more speeders than they would if they did not use the cameras. It would cost a lot less for the state because they would not have to hire as many authorities specifically highway patrol officers because the cameras would catch whoever was speeding. Another advantage would be that the authorities can catch people that abuse their car and speed much too often and put others in danger, by doing this it would take more people off of the street and keep things safer. However the disadvantages of this are that the police officers would become lazy in their duties because they would not have to do as much, and it would lead to problems politically because people do not have as much freedom. They are taken away from their freedom because they are constantly being surveyed which leaves them with no way to escape the authorities and ultimately the government as a whole. The disadvantages outweigh the advantages because if this were to happen it would cause havoc in the the world because people would be raped of their freedom and many rebellions and revolts would be the result. I believe the disadvantages outweigh the advantages because I believe it is important to have our freedom...

1.)Multimedia- The use of computers to present text, graphics, video, animation, and sound in an integrated way. Long touted as the future revolution in computing, multimedia applications were, until the mid-90s, uncommon due to the expensive hardware required, media and content that uses a combination of different content forms.
2.) Two methods that can be used to reduce the amount of disk space are that the media can be condensed on the disk. With the media that is located on the desk being condensed, there would be a lower bit rate and most importantly there would be fewer pixels that would reduce the amount of disk space. Another method that could be used is to link graphics instead of embedding them because when they are linked all of the information is stored online rather than on the disk. It opens up more disk space and file compression is a method that can be used to reduce the amount of space because the information can be compressed.
3.) Some organisations choose to train their staff using multimedia training packages over face to face instructing with a human instructor because it offers more variety and possibilities than a human could. The multimedia training packages can present and show text, graphics, video and animation that can cause the trainee to learn faster and more efficiently. The multi-media can quickly train the staff because it can use videos of tutorials of how to do certain things, while a human instructor would not be able to do is as quickly and efficiently because they cannot provide step by step instructions as detailed as a video would. The advantages of multimedia training package is that it can cover all the basis, meaning that it can digitally show the trainee how to do the work, as well as have the sound of the work being done. It is advantageous because it saves the company more money because they can constantly reuse the package on new employees and will not have to pay the human instructors a lot of money to do their job. The disadvantages however are that the employee can not have the valued face to face time with an instructor that they can relate to and ask for help or questions when needed, but multimedia they can do it at their own pace and pause or rewind the video or sound when needed.

1. What are two limitations of the wii as a simulation? Two limitations to the wii as a simulation are that it does not accurately provide the physical actions as the real sport would. For example when playing wii sports, you are not actually swinging the bat and running the bases, as you would in real life, so the simulation does not give that real sense of work-out and does not include the correct amount of physical action. A second limitation to the wii as a simulation is that it does not provide the work-outs people or humans need to provide the right amount of physical activity to stay healthy and have it count as a work-out, the wii simulation does not target the rest of your body rather than just your facial area and mainly your arms. As a result it is not a real work-out.
2. Two other potential uses of the technology incorporated within the Wii video game console is that is that you are able to stay in communication with others through the use of the Internet on the Wii. The Wii can play 'online'against people and also gives the opportunity to surf the web through the web browser incorporated into the Wii. Users are able to check their social networking sites, email, and other websites through the wii. The ability to be able to do that shows how convenient the Wii is because people can use it instead of using the Internet through another device such as a computer. The technology in the Wii can be used to communicate with others through sites online as well as face-to-face chat as video cameras can be incorporated into the wii. Another potential use of the technology incorporated into the Wii video game console is a motion sensor. The Wii is only able to be used when the motion sensor is activated with the controller, and with that technology, a motion sensor could be activated that shows whenever somebody or something crosses the path of the television or wherever the wii is located. With this technology, people would be able to track whoever passes through their house and possibly catch a predator or an intruder in their house. The motion sensor can show what is in their house or passing through it and the possibility for crime to decrease could happen.
3. Wireless communication can be done through the process of signals through satellites and objects like telephone poles. The receiver sends a signal to the transmitter and it is picked up and opened and the information is relayed from one to the other. Two devices that are not connected connected that can communicate are the Wii controller and the the wii itself. The wii controllers movements and buttons are received by the transmitter which is the motion sensor at the top of the television, the motion sensor relays the information and movements of the controller and relays them to the Wii console itself. The effect of this is that it is a lot more convenient because it is wireless technology that allow movements to be a lot more easier and comfortable.
4. The role of video game consoles in the healthcare of the elderly is huge. The elderly use the video game consoles as a way to have steady, easy workouts that are very feasible for old frail bodies. Video game consoles provide the elderly with the opportunity to work-out and move in the comfort of their own home or place of living, with limited stress or exhaustion. The elderly can use the game console at their own pace and stop whenever they please, opposed to other traditional work-out machines like treadmills that do not stop and are not controlled as easily. The advantages of the role of video games being big on the healthcare of the elderly is that it allows the elderly to work-out very comfortable and just be able to move with not as much effort as real work-outs would. The advantages include that the elderly can prevent their arthritis from getting worse because their hands would always be in movement when working and using the video game consoles, also the elderly can stay in movement and have fun while doing it, they will be motivated because it is a fun and happy way to work-out which keeps their old depressed lives filled with fun and happiness and they can collaborate together and have fun, because at an age like that they do not have many friends at all. However there are some disadvantages of the video game consoles having a big role on the healthcare of the elderly, they lose the real work-outs and life experiences of the real world. They do not walk as much and experience the outdoors because their workouts can be done quickly and efficiently through the game consoles and they lose interaction with the real world and its surroundings. The advantages outweigh the disadvantages in this case however, because the game consoles give happiness, and a reliable work-out to the elderly which they would not receive if the game consoles did not exist. It is something that is fun for them and fun is needed at that age, as well as keeping their health up by always having them moving and interacting with others.

1. Define the term resolution- the number of distinct pixels in each dimension that can be displayed
2. Two interactive services that could be provided with digital TV are video-on-demand (Comcast on demand)and DVR. Users are able to control the content of what they are viewing when they use these services because that is why they are there. The users are able to pause, fast forward, and rewind what they are viewing because of the digital TV and it's interactions. The interactive services provide the user with more convenience and more time on their hands.
3. Two ways a domestic installation such as a digital TV can communicate with the digital provider is through the cable/box. All of the interactions that are made on the TV whether it is buying a movie, or watching certain shows on pay-per-view, the digital provider has to have access to these transactions in order to charge the owner of the digital TV for what they have purchased. The digital providers have access to the cable/box and all that is purchased through the cable box. Another way is the binary digits and satellite communication the TV has. The digital providers are able to identify what the TV user is watching and purchasing through the satellite communication. Each digital TV needs binary digits as well as satellite communication in order to function and work correctly because there is no other way of solid communication.
4. The growth of video clips on the Internet is increasingly taking over the need of digital Tv. When viewers watch movies, shows, and documentaries on the Internet, they are most always free of charge, unlike a digital TV that is a hefty price. Video clips are becoming much more popular because not only are they very cheap, they are very convenient and their is no subscription or money transactions needed to view the clips, if their is an internet connection, video clips can be viewed. They are slowly but surely taking over digital TV because they make more sense financially as well as logically. On Video clip sites like Hulu, you are able to watch many free shows and episodes that are seen on digital TV, as a result many people wait till they come out on the website to watch them because if they have a laptop they can be viewed from anywhere. The disadvantages of video clips taking over digital TV is that it is a possibility that in time there will be no digital TV and Internet clips will be the only form of viewing television, however an advantage would be that people would not have to pay for shows or movies that they wanted to see anymore because they could just be seen for free on the internet. The affect of this is that it shows how the Internet is taking over the world and everything that is digitized because it is so much easier and better to use than perhaps digital TV.
4. A key field is a field or set of fields of a database table which together form a unique identifier for a database record.
B. The process used to create a query which would produce an alphabetical list of all citizens who were born after 1990 and have suffered from diabetes that do not smoke would consist of making a query using the query wizard, and identify the key fields that contain names, diabetes, smoke, and when the people were born. For the criteria of the query you would enter 'yes' for diabetes and 'no' for smoking, and then followed by the birthday using the < symbol.
C. Data matching is the task of finding entries that indicate the same entity in two or more files. Record linkage is a good and common technique when you have to join data sets that do not have a unique database key in common. Data mining is the process of taking out patterns from huge data sets by combining methods from stats and artificial intelligence with database management. With reference to the Icelandic database, the data is made anonymous by replacing the persons name with an ID number, which is used as a key field in the database. Citizens are required to give their personal information.
D. The advantages of medical research outweigh the concerns of the Icelandic citizens about storage of their genetic data to a very large extent because the medical research is saving their lives. The medical research is what is keeping the Icelandic people alive so there is no reason for them to be concerned about how their data is being stored. Without the medical research, the Icelandic people would not have any medical records at all, and would be in jeopardy of death or disease. The advantages of the medical research is that it allows Icelandic people to have treatment as well as identify any of their diseases, and the advantages of it being saved is that if there are any problems in the person further in their life they can be assessed by the medical records that have been saved.m The disadvantages of the medical research is that it takes away some of the freedom for the Icelandic people and exposes their enclosed culture, and a disadvantage of their medical records being saved in a query through an ID number is that their privacy is being somewhat violated and not taken into consideration. The affect of this is that the Icelandic people feel as if they are not being treated as fairly as they should, however the medical research outweighs their concerns because it helps the people. The advanced medical research is a lot more important than the simple concerns of the Icelandic people. Medical research and life saving is more important than privacy.

(a) From the simulation shown in the Diagram on the previous page,
(i) identify one input [1 mark]
Sunlight
(ii) identify one output. [1 mark]
Heat
(b) Describe two tasks which must be performed in the development of simulation
software like that used in the Diagram on the previous page. [4 marks]
Two tasks which must be performed in the development of simulation software like that used in the Diagram on the previous page are how the inputs and the outputs on the structure. If sunlight is added, the user needs to know what the sunlight will produce and how much of it will be produced. Another task is the latitude and longitude, area, and time of the simulation because they all have to be taken into account when focusing in on the real thing, rather than the simulation because they are real life things. The affect of the outputs and inputs of the simulation is that it determines how the real thing with interact with the elements at hand. The affect of the longitude, latitude, area, and time is that they are necessary in determining the outcome and progress of the product.
(c) Explain two advantages of using simulations to design products such as
greenhouses. [4 marks]
There are many advantages of using simulations to design products such as greenhouses, two main advantages would be that they will show and determine how the plants will grow, as well as how much sunlight will be in the greenhouse. The affect of the determination of knowing how much the plants will grow is an advantage because farmers will know how much plants to put in the greenhouse, how long it will take them to grow, and ultimately what kind of plants to grow. Determining how much sunlight will be in the greenhouse is an advantage because it will show the growth and how fast the plants will grow because sunlight is very valuable to the growth of plants and the more there is the faster the plants will grow.
(d) To what extent are simulations such as this useful in enhancing the teaching and
learning of a science subject? [10 marks]
Simulations are extremely useful in enhancing the teaching and learning of a science subject to a large extent because they can determine how any experiments or science related activities will come out. Simulations have the ability to determine the outcome of a series of events based on the knowledge that is put into them or that is available. They are useful in enhancing the teaching of a science subject because they show how the factors that are put into the subject interact with everything else. The simulations determine the inputs, outputs, flows and stores of the subject or any experiment and are very useful to teachers in teaching a certain subject because it is something that can always be referred to or shown. The teachers will have more free time to create better lesson plans. The students can use it to determine their experiments and outcomes and it will create them to always be able to know what they are seeing and doing.

Simulations!
http://www.domain-b.com/technology/20110307_simulations.html
How well do modelers understand the underlying science or theory of the system being studied?
Modelers understand the underlying science or theory of the system being studied very accurately because the simulation has matched with the actual reality of the simulation that is being studied.
How well understood are the relevant properties of the materials involved?
The relevant properties of the materials involved are understood very well because it is a very accurate simulation because those who enter the data in have studied it very a long time because it is their job, and other similar simulations have been used and have been done for the same process.
How accurate and complete are the data?
The data is very accurate and complete because it is proved that it matches with reality and that the simulation was exactly like what the real thing was. Meaning the simulation was a perfectly accurate representation of the teams in this case.
What are the assumptions and simplifications of the model?
The assumptions and simplifications of the model are that teams will win based on their record, players, coaches, and past experience in tournament play. All has to be taken into account when deciding which team will win which game. The assumptions are that a player or a certain coach will make the team win, rather than what really happens.
How closely do the results or predictions of the model correspond with results from physical experiments or real experience?
They are somewhat close, however there are no real physical experiments done to determine the winner of a series of basketball games. There is so many different factors that go into the process and are all in the future that it is impossible to do physically, it all has to be done through hypothetical simulations.

4.5/4.6/4.25/4.26/4.28
4.5-
1. The questions used to evaluate computer models are.....
How well do the modelers understand the underlying science or theory (be it physics, chemistry, economics, etc.) of the system being studied?
How well understood are the relevant properties of the materials involved?
How accurate and complete are the data?
What are the assumptions and simplifications of the model?
How closely do the results or predictions of the model correspond with results from physical experiments or real experience?
4.6-
The climate and car crash model use the simplification of a grid. Grids vary in different sizes and climate models stimulate roughly 100 years over. Due to the grid limitations, small storms, clouds and other small phenomena that fall between the grid points and are not accurately represented. The car crash is the same way because it is done in steps and things can fall through the good points.
4.25-
An argument in the defense of the experience firefighter is that he has been on the job for over 25 years, and that shows that he has a lot of experience doing controlled burns. The computer can possibly make suggestions on when to burn, but the man's judgement is just as strong because he has done this sort of thing for half a century, proving that the decision he makes will most definitely be the right one. Computers have very accurate calculations, but they are not able to be there in the moment, and can't have the emotions or feelings there are when a decision is being made, they do not have the first hand account of being there.
An argument in the boss' defense is that computers have the best judgement out of any human. (As shown on jeopardy through Watson the computer)The computers job is to accurately narrow down the time in which the burning is to take place, and if the recipients follow what the computer says than everything will go smoothly and there will be no chance of danger or injury.
4.26- My decision would not be affected by the company's policy about testing. The factors that are most important to me are what the company chooses to do after the testing has been done. If the product did not do well in the testing simulations or physical tests, than the product should not have been distributed in the first place. Every company needs to make sure that the products they make and sell are completely safe and people will not sustain any serious injury, if the company chooses to go against that policy than they should absolutely be reprimanded and face the repercussions that are to follow. In my personal opinion I think that everything that is sold should have some kind of insurance that no serious injury or death will be sustained involving the product, if company's do not pay attention or care about the testing, than they can burn in hell and go to jail because i'm not buying their stuff.

1. I believe the model that predicts the effect of an income tax change on government revenue would be less reliable. Income tax can change at any time for any number of different reasons, whether it be some sort of natural disaster, another recession, or something having to do with only the government. Income tax is something that cannot be predicted or calculated and as a result a model that is suppose to predict the income tax would not be entirely accurate. In my opinion it would not make the right predictions most of the time.
2. I believe the model that can predict the position of the moon in relation to the earth, 30 years from now, can produce very accurate results. The atmosphere and it's surroundings are things that can be predicted very easily and accurately just by studying the patterns and history of the moon, history tends to repeat itself when it comes to space and how things interact with each other and move around, so I believe the predictions would be very accurate.
3. I believe the model that can predict how much optical fiber will be needed in a major city thirty years from now will have much less reliable results. There is no possible way to calculate how much optical fiber will be needed in a major city in thirty years because the population is growing at an exponential rate and then you have to combine that with the size of the people in a city and that can change in many different ways over the span of thirty years so the results would not be that accurate.
4. I believe the model that can predict how much CO2 will be emitted worldwide by burning fossil fuels for energy fifty years from now will not be accurate at all. Fossil fuels are declining as we speak and so calculations could not be made based on how much fossil fuel is available to us in today's time, because that will change and there is no guarantee on how much there will be in fifty years, so the results for how much will be burned will not be accurate.
5. I believe that models that predict the speed of a new racing boat hull design under specified wind conditions will be very accurate. The model can obtain the results of other hulls that are in commission and compare them to the new hull that is being made, and test the new hull in wind conditions and the model will be able to create a database of all the different mileage of winds and then directly relate them to that certain hull.
1. The questions used to evaluate computer models are.....
How well do the modelers understand the underlying science or theory (be it physics, chemistry, economics, etc.) of the system being studied?
How well understood are the relevant properties of the materials involved?
How accurate and complete are the data?
What are the assumptions and simplifications of the model?
How closely do the results or predictions of the model correspond with results from physical experiments or real experience?

The climate and car crash model use the simplification of a grid. Grids vary in different sizes and climate models stimulate roughly 100 years over. Due to the grid limitations, small storms, clouds and other small phenomena that fall between the grid points and are not accurately represented. The car crash is the same way because it is done in steps and things can fall through the good points.

An argument in the defense of the experience firefighter is that he has been on the job for over 25 years, and that shows that he has a lot of experience doing controlled burns. The computer can possibly make suggestions on when to burn, but the man's judgement is just as strong because he has done this sort of thing for half a century, proving that the decision he makes will most definitely be the right one. Computers have very accurate calculations, but they are not able to be there in the moment, and can't have the emotions or feelings there are when a decision is being made, they do not have the first hand account of being there.
