problems in the world which have an effect on climate change. The issue that will be discussed is all the fuels and gases that are emitted by cars. The emission produced by cars is one of the mayor aspects affecting climate change. There is a lot of car pollution due to the many cars being used all the time by many people all around the world. Many of the cars emit gases, which harm the atmosphere, increasing the rate of climate change. These emissions bring quite a lot of aspects which are being affected
on the topic of electric cars because of the new technical innovations that take place every day and the constant information around us about preserving the environment. The central question of this research is „why is the number of electric cars in Europe still limited?“ In order to answer this question , different desk research methods were chosen as in statistics, blogs, books, and articles. Information was gathered and analyzed on advantages and disadvantages of electric cars, also about alternative
1. (A) What are alternatives? Alternatives are the raw material of decision making. They represent the range of potential choices you’ll have for pursuing your objectives. There are two important points that should be kept in mind at all times. First, you can never choose an alternative you haven’t considered. Second, no matter how many alternatives you have, your chosen alternative can be no better than the best of the lot. 1. (B) Why is it so important to consider them when making decisions
causing the pressure to increase at a constant volume till point ‘2’. The exhaust stroke happens between points ‘3’ and ‘4’. The piston ejects the burnt gas through an open outlet valve. The efficiency of the Otto cycle is n=1-1/r^(ɣ-1) where r is equal to v1/v2 also known as compression ratio. The Diesel engine was developed by Rudolf Diesel. It is similar to the Otto cycle with one of the differences being that the engine takes in air rather than combustion mixture. The diagrams below demonstrate
of the XX Century the first electric cars were produced, of which the 28% worked with electricity. The car at first was a mean of transport that only rich people could afford, but with Henry Ford and the new production techniques and models, the prices became each time lower. And as soon as people started to buy them, the landscape change drastically. In 1950, the roads started to improve and in the USA, for instance, the residential areas were thought to be used by car-drivers. After that stage,
health-related Work noise is often regulated by health ministries and worker's unions, Noise is described as an unwanted sound but this is subjective definition as one man’s sound may be another man’s noise.1 Physically there is no distinction between sound and noise. Sound is a sensory perception and the complex pattern of sound waves is labeled noise, music, speech etc. Environmental noise is a common cause of hearing loss in industrialized societies. When the noise exposure causing hearing loss
CHAPTER 1 INTRODUCTION 1. INTRODUCTION 1.1Bipedal Robot:- The term bi-pedal robot refers to a robot that walks on two legs. In the recent years there has been much interest stimulated in dynamic walking in bipedal robotics and legged locomotion in general. Part of reason for this interest is the need for robot which can operate in human oriented environments. Human presents a very elegant model of locomotion to emulate. The Bipedal robots will operate in the human environment with much
