STELLA Science Simulation Software.
Simulations can be considered a variant of cognitive tools, for example they allow students to test hypothesis and more generally "what-if" scenarios. In addition, they can enable learners to ground cognitive understanding of their action in a situation. Simulation is a powerful tool for analyzing, designing, and operating complex systems. It enables you to test hypotheses without having to carry them out, saving you thousands, even hundreds of thousands of dollars. It is a cost-effective means of exploring new processes, without having to resort to pilot programs. Simulation provides a method for checking your understanding of the world around you and helps you produce better results faster. And it is an efficient communication tool, showing how an operation works while stimulating creative thinking about how it can be improved. Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games. Training simulators include flight simulators for training aircraft pilots to provide them with a lifelike experience. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real

Bryan Carroll P6 Digital Graphics Explain potential legal implications of using and editing graphical images. Write a report that includes: Explain the legislation and legal implications of Copyright Designs and Patents Act 1988 in relation to using and editing graphical images. Describe a situation when using a graphical image would be in breach of the Copyright Designs and Patents Act 1988. Copyright Design and Patents Act 1988 This law is in place so that the creators of certain materials can have a kind of stronghold over people that use or edit their graphical work so that if it is taken illegally, they will be able to take the culprit up to court. For example if someone took an image off the Family Guy website, reproduced it somewhere else and did not ask permission of the creators, they are breaking the law. They would need to have a liscence for such images to be reproduced. Also if an image is taken and is edited so that it looks nothing like the 1st image it is still illegal, as the base image is still the same and has no lisence. A few ways that people can break this law whilst using graphical images are as follows; . If an image is taken and then sold and or hired 2. If the image is taken within the UK and is not intended for personal use. 3. Also if someone takes a copyrighted graphical image and places it in public exhibiting it they are also breaking
Ecommerce Case Study
In order to begin E-commerce for the Cuckoo Games would be required to have an Internet Service Provider or more commonly referred to as an ISP. An internet service provider is a company that provides individuals and other companies access to the Internet and other related services. These services could include Web site building and virtual hosting. The reason that an internet service provider is required is because they have the equipment and the telecommunication line access required to have a point-of-presence on the Internet for the particular area. A point of presence is an access point from a particular area to the internet. The larger ISPs have their own high-speed leased lines so that they are less dependent on the telecommunication providers and can provide better service to their customers. The internet service provider will enable Cuckoo Games to connect to the internet and open them up to a number of other opportunities such as an online website, online payment methods and ultimately selling their products online through E-Commerce. It is essential for Cuckoo Games to have a sufficient computer network with a specification that will be able to cope with working online. This may mean that Cuckoo Games will need to purchase more equipment or improve existing equipment. In order for Cuckoo Games to benefit from E-Commerce they must have a few essential pieces of
Compare the effectiveness of different transmission methods.
unit 10 communication technologies D2 compare the effectiveness of different transmission methods. Comparison of the effectiveness of different transmission methods are chosen in particular situation for a technological technology has progressed to a number than any other technology has ever progressed to, thus this progress has enabled for data to be transmitted using wireless technology. The following, mobile phones, radio, microwave and the internet are all a type of communication methods that use the technological advancement in wireless data transmissions. The wireless data transmission is a type of system that will transmit invisible electromagnetic waves to transmit data over a long/short range within a short amount of time. Of course there are many more ways to transmit information or data signals over a transmission method and this is only one way to send information or data signals. Radio: effectiveness of different transmission radio is basically a wireless media that transfers data by carrying electromagnetic waves with maybe long or short transmission (frequency) to distant or close by location in just a very short amount of time and it does that through the electrical conductor and the antenna that is attached to the radio. The electromagnetic waves that the radio sends with either the low and long frequency are regulated by the federal communication

Matthew Dickinson INFO 1- Sample Work 2012-2013 Centre Number: 34349 Candidate Number: 7049 Analysis - Problem identification with a list of requirements. Plus Interpretation of them as input, Processes and Output Company Background I have been asked to create an ICT solution for a local events and promotions company called; EVDOP Live. EVDOP Live is a company located in south Liverpool who provides an exclusive service in which they promote various local bands/musicians and organise gigs and events within various local venues. Prominent examples of the venues that EVDOP Live use are; The 02 Academy, the Liverpool guild hall of students and lastly the Liverpool philharmonic hall.

EVDOP would contract a printing company to print the venue tickets, and then sell them to the prospective performers at a slight increase of price; is in order to make
Human Interface - visual perception and models of interaction.
Michael Gill Unit 23 Task 2 Perception Colour e.g. trichromatic system Colour affect users in several of ways such as some people find yellow font very hard to read on a white background and some find it very easy to read. For 3D effects the trichromatic system is designed, which consists of three main different colours. These are red, blue and green. Selecting the right colour when a GUI is designed is essential. If the GUI has wrong colours or dull and boring doesn’t attracts people to use it. Microsoft Office 2007 has grey as its main colour which is very boring, but the blue used on the toolbar makes it up for it and the orange highlight of the selected tools make it more abstract. These colours are very eye catchy and don’t make it look boring. Perception luminance Luminance is how bright a light colour appears to a viewer and that which our brain can handle. For instance, if a bright yellow font would be displayed on a white board could make the text hard to see or to read. Designers of GUI do not take any consideration of the user’s computers screens brightness. So for that reason the rule is in order to display the best details means to use luminance contrast. Perception Pop out effect The Perception pop out effect, allows something to "pop out" on a display. A target made up of a combination of non-unique features that normally cannot be detected
Social Implications of E-Commerce
Social Implications of E-Commerce The vast majority of products one would ever need to purchase can be found on the internet. A few clicks of the mouse and anything you could ever want can be sent straight to your door, but this wasn't always the case. Online shopping - something a lot of us couldn't do without these days - is a fairly recent development. In 1991 a ban on commercial businesses operating on the internet was lifted, paving the way for e-commerce websites to develop. Amazon was launched in 1995 and set the standard for customer focused e-commerce websites, despite the fact it did not turn a profit for 6 years. eBay was launched in the same year and by 1996 had sold $7.2million worth of goods while having only two full time employees. Before Amazon and eBay opened the gates of e-commerce customers had two choices for their shopping needs - brick and mortar shops or mail order catalogues. Word of mouth was very important for businesses as customers had limited means of price comparison or product reviews; unlike today where a simple web search can show in an instant which stores have the cheapest prices or which products are the most popular. With websites such as Groupon or Wowcher consumers can get huge discounts on products or services that would otherwise not be available. This information is also available to the business; which means they can always know
Compare and Contrast Major console platforms
Kyle Walton AO1 – Compare and contrast major console platforms One of the major console platforms is Sony’s Playstation. Sony offers you many different ‘unique’ features such as six-axis controller, free PSN and blu-ray. Six axis controllers is a feature of the Playstation where you can use the controller as a steering wheel for example. The six-axis controllers cost £30 when new as it was a new technology, the battery of the controllers lasted for 30 hours of continuous gaming from full charge. Blu-ray discs are better quality than HD disc and have a capacity of 128 GB which means the PS3 exclusive games are larger than other console games. Although PSN is free it isn’t the best online gaming service there is that goes to Xbox live. The biggest PSN problem is that the service was hacked in 2011 and this proved that it is insecure and people will not be willing to pay. Another major console platform is Microsoft’s Xbox 360 these have features such as Xbox live Sky player and Zune. Zune is a film and music player where you can watch and listen to music from the internet. Sky player allows you to watch movies and programmes from sky on your Xbox without a Sky box. But you have to have a subscription to sky. And Xbox live is what allows you to play online with your friends on your Xbox although you have to pay for Xbox live it is better than PSN as there is more
Evaluation. In this unit of controlled assessment I have developed a website using multimedia software. The website provides guidance for new pupils starting secondary school.
Evaluation of Unit 4 Controlled Assessment In this unit of controlled assessment I have developed a website using multimedia software. The website provides guidance for new pupils starting secondary school. I have produced 6 linked web pages in “Dreamweaver” which are suitable to fulfil its purpose. Evaluation of working practice Generally, I felt that the way I carried out my tasks was good and well. Before, I started the assignment, our teacher allowed us to familiarise ourselves with new software and how to use certain techniques effectively. Some tasks in this assessment were worth more marks and required more time; therefore I managed my time wisely. In the beginning of my controlled assessment I primarily created suitable folders in order to store my files. The folder was suitably named “Unit 4 Controlled Assessment,” in this folder; sub-folders were created for each task carried out in the assessment. This folder structure enabled me to store the files I needed in a logical way, so that it was easy to refer back to various aspects of my work, such as my animation. I also ensured that my folders and files had appropriate names so that it was easy to navigate through the folders and find what I was looking for. During the completion of the assessment, I ensured that I was constantly saving my files and producing back-up files. I did this by using a USB stick
