Building and testing a sensor to determine number of degrees to which a window is open.

Alex Furber 12HW Sensing Project 20-02-02 Building and testing a sensor to determine number of degrees to which a window is open INTRODUCTION When making use of a greenhouse to grow plants out of season or on a large scale for commercial reasons, the temperature within the green house must be carefully regulated, in order to ensure that the plants are under the optimum growing conditions. With the windows shut permanently, the temperature may become too high, and the windows need therefore to be opened. This will allow the temperature to drop back to the correct level. Different numbers of degrees to which the window is open have different cooling effects. For example, if the window is open by 50 degrees, then there is probably a more rapid cooling effect upon the greenhouse than if the window was 10 degrees open. Thus, it is important to know how many degrees the window on a greenhouse is open. It could however be very time consuming for people to check the greenhouse(s) manually, or particularly problematic if the temperature should become a problem during unsociable hours. It would be extremely useful, then, if a sensor could be attached to the windows of a greenhouse, and a reading sent back to a control room as to how open the windows are. Someone could then either use a motor attached to the window to alter the setting, or adjust the window manually. My sensor

It is widely believed that toys influence the emotional, social, mental and the physical development of children. They play a great part to the early years of a person's life: to occupy and to teach. So it is important what toys children play with and the quality of them. For many centuries children have been interested in toys. Prehistoric toys must have existed because children and adults have used their imagination to create toys out of any materials. Objects have survived which have been made out of terracotta are expected to be around 3000 years old. These were made in the Mediterranean and the Near East, and were models of animals and some pull along toys on wheels. It has been proven that Egyptians, Romans and Greeks have mad toy for children these include dolls, terracotta animals with moving parts or wheels, Egyptian wooden figure of a man games with dice, marbles and counters, hoops, yo-yos kneading dough and knucklebones. Toys such as animal figures, balls, spinning tops and toys with simple mechanisms are found in most cultures in the world. Many toys have a simple movement within the toy. Among them are jointed figures sent into acrobatic antics by pressure or torsion, devices activated by swinging

Research question: Do the Chinese fast food chains in Hong Kong behave in oligopoly structure?

Research question: Do the Chinese fast food chains in Hong Kong behave in oligopoly structure? Forward When talking about fast food, most people will think of McDonald's. In fact, Hong Kong, a melting pot between east and west, Chinese fast food also captures a significant share in the fast food market. It is closely related to every Hong Kong people's life. Although a lot of researches have already been conducted to investigate the fast food market, most of them are targeted at Western fast food. There does not seem to have many researches which focus on Chinese fast food. In fact, Chinese fast food is actually totally different from the Western fast food. Because of that, I think it will be very interesting to investigate the Chinese fast food market in Hong Kong. My concern will be how this market works, how the chains compete with each other, and how their business strategy different from those Western fast food chains. Among the Chinese fast food market, Café de Coral, Fairwood, and Maxim are the biggest three Chinese fast food chains in Hong Kong. From the economic view, this is called the oligopoly structure, which is characterized by the domination of market share by relatively few competitors. If that is the case, the equilibrium price tends to be very stable. However, in reality, these Chinese fast food chains need to lower their prices together regularly. Because

Investigate and construct a sensor.

AS LEVEL PHYSICS SENSING COURSEWORK In this physics coursework, I have been asked to investigate and construct a sensor. I have chosen to examine sound and to develop and make a sensor, which would detect how loud specific rooms in the school, may be by the noise, which would be produced by a stereo system. I would create this sensor and compare my readings, which are produced, with the actual sensor used to detect how loud sound is. I would use this decibel meter and see how accurate my sensor is. PLAN: Aim: My aim of this experiment is to see how precise my sensor is compared to the real sensor that is the decibel meter. I would evaluate my sensor and compare the two sensors against each other using my results obtained. Method: I had firstly planned to measure sound in different rooms in the school, by making the actual sound sensor. I had made this sensor by using a microphone, power pack, crocodile clips, ammeter and Voltmeter. I had connected this circuit up in series and then additionally added the microphone into the circuit. However when switching the power pack on, I found that there was a reading given by the voltmeter and not the ammeter. Therefore, I had thought about my experiment and realised that I needed to use a sound generator, loudspeaker and I needed to use the Oscilloscope. The previous attempt would not have worked as I recognized that I needed a

Electronics Coursework Problem An electronics firm wishes to introduce a range burglar alarms. This coursework contains the design and a prototype, which has been made for further development by the firm. Possible Projects Brief I have decided to design and make a prototype of a home burglar alarm. Research into Alarms - I have phoned companies, talked to staff at electrical shops, to find the following information. Analysis of commercial alarms From my research into commercial alarms I have found out the following... * All alarms have more than 1 input. * All alarms sound for a time after they have been triggered. * Most alarms sound for a variable time of between 2 minutes and 20 minutes. * All alarms have a sound output of at least 98dB. * All alarms have either a delay between being switched on and being armed or they can be remotely switched on and off from outside the premises. * The better alarms have a small delay between being triggered and the siren sounding. Research into Burglaries - To Catch a Thief The following research came for the television programme 'To Catch a Thief'. The presenters are ex-burglars, who have decided become good to help people prevent burglaries. First the ex-burglars find a house, burgle them (with the householders permission), and then the BBC pay for extra security to be fitted e.g. Burglar alarm, new locks, windows, and

What makes a balanced diet?

What makes a balanced diet? A balanced diet is a diet that consists of a variety of foods. It should be based on bread, potatoes, cereals and lots of fruit and vegetables. You should also have a moderate amount of milk and dairy products, meat, fish or other alternatives (if vegetarian/vegan). It should contain a limited amount of fat and sugar. Eating a healthy diet can help to prevent obesity, malnourishment and vitamin deficiencies. It can enhance you overall well being and prevent a number of diseases and cancers. It is important that you consume a wide variety of foods to maintain adequate intakes of vitamins, minerals and dietary fibre, as these are important to your health. Protein is needed for growth and repair of the body and it also gives us energy. Amino acids are the building blocks of protein and different foods contain different amounts of these. Different foods vary in the amounts of protein that they provide. The main sources of protein are meat, fish, eggs, milk, cheese, cereals and cereal products (e.g. bread), nuts and pulses (beans and lentils). A majority of protein can be obtained from animal sources i.e. meat, fish, eggs and dairy products. Further protein can be obtained from cereal products, and nuts and pulses. The following chart shows the percentage of protein that is in each food. Protein is broken down by digestion into amino acids,

ICT - Microsoft Publisher, Pizza restaurant menu.

GCSE ICT PROJECT Microsoft Publisher Pizza Restaurant Menu Part One - Identify Statement of the problem Mr Suits is the owner of a pizza restaurant - "Pizza Colosseum". Mr Suits wants to open up new branches. At the moment his restaurant only has a very dull looking and unattractive menu. It is simply a list of the food available typed up using a word processor. Although he has many regular customers, many of his customers judge the restaurant when they see the uninspiring menu. He needs a new menu in order to attract more customers to raise enough profit to expand. Sometimes, the customers want to know whether a dish is vegetarian or not, spicy or not. They also want to know what ingredients are in the pizza, sometimes the waiters/waitresses are busy and do have the time to answer these questions or do not actually know them. Consideration of Alternative Solutions One solution could be to produce an attractive menu by hiring an artist to draw up an eye-catching menu. This could then be colour photocopied and distributed. However, colour photocopying is very expensive and a hand drawn menu does not seem very professional. Every time the menu has to be updated, the artist has to be hired again and the design photocopied all over again. Another solution could be to use the current word processor method but add the extra needed content such as description of
