Information Technology - Human Computer Interaction (Evaluating Website for usability) - Essay Example One of these handfuls of researchers who helped build the internet in the 1970’s .The world we see now has become a global village. The internet has made this world into this global village .We see hustle and bustle everywhere, houses, gardens, schools, colleges, universities etc .Since now the world has become such a global village it has made man more inquisitive and competitive at the same time. Every man today wants high living standards, good education, high quality of food and leisure etc. To cater this never ending flow of human wants and needs, groups of individuals formed organizations, and then the process of production and marketing, selling came into being. It is also a fact that in the fast paced world we live in today, things are in flux almost always. What was a trend a decade back may not be evident anymore. The world has been completely invaded by modern inventions. The vast exposure that internet has provided to us has resulted in bringing about great change to the mind sets of people. Various organizations and institutions small and large tend to market their products and services differently. For e.g. marketing through print media, electronic media etc .these ideas came more into being because of the individual wants and needs and how humans were to cater to those. This also then helped individuals identify and prioritize their needs. A prime value of ‘Education’ exists, this has all along been the vital contributor to wards the evolution of man. As time has elapsed both young and old have this clear in their minds that they need to acquire quality education in order to exist respectably in this world. There are different modes of advertising of products and services .This is done in order to help satisfy themselves and others around them. Initially schools, then colleges and now universities with huge campuses, state of the art facilities and accommodation are being

Maths - Essay Example 1. A hydroelectric project is expected to create a large lake into which some fish are to be placed. A biologist estimates that if 10,000 fish were introduced into the lake, the population of fish would increase by 50% in the first year, but the long-term sustainable limit would be about 60,000. Form the information above, write two ordered pairs in the form where . Hence, determine the slope and equation of the linear growth factor in terms of . It is also given that the long-term sustainable limit of population of fish is 60,000. This will be case when there is no increase in fish for next year, therefore, the growth factor (r) for this case will be equal to 1. Since, a logistic population growth model takes a similar form as the geometric population growth model. However, in this case, the growth factor depends on the size of the population and is variable. In previous section 1, the equation of growth factor (r) is determined, which is: 4. The biologist speculates that the initial growth rate may vary considerably. Following the process above, fine new logistic function models for using initial growth rates 2, 2.3, and 2.5. Describe any new developments. From table 2 data, it can be seen that for higher values of initial growth rate r (2, 2.3, 2.5 and 2.9), the logistic model does not correctly determine the population of the fish over the 20 years period. For example, for initial growth rate of 2, the fish population exceeds stable population (60,000) three times; for initial growth rate of 2.3, the fish population exceeds stable population (60,000) eight times; and for initial growth rate of 2.5, the fish population exceeds stable population (60,000) nine times. For initial growth rate of 2.9, the fish population exceeds stable population (60,000) ten times and sometimes it touches the population value of approximately 70,000. For initial growth rate of 2.9, the fish population exceeds stable population (60,000) ten times
