mathematical modeling‚ statistics and algorithms to arrive at optimal or near optimal solutions to complex problems in an organization. In an operational research project there are 5 phases‚ namely‚ problem identification‚ formulating problem‚ deriving solution validating model and lastly‚ the implementation of results. The first phase is to identify the problem through the observation of its symptoms if it is not obvious. Relevant questions to what the problem is about are asked to clear any doubts and the

Phase Change Lab Written Response Our objective in our phase change lab was to record observations of the increase in temperature (in Celsius) as water changed from solid to liquid to gas over a hot plate. This lab report will discuss quantitative and qualitative data contained in the lab‚ how energy is related to phase change in water and an elucidation of how melting point and boiling point relate to the physical properties of matter. This paper will basically outline the lab done in class

Play is important to our young children especially focusing on Grade R children. Some children who are entering the foundation phase for the first time have never experienced how it is to play with other children. Children will start learning how to interact with others‚ how to share‚ how to solve problems and how to use their fingers in different kinds of ways. Another reason why children play is because they enjoy it‚ as quoted by Mardi Lucich “Children play because it is fun. Play takes many forms

Human resources management consists of all the activities involved in acquiring‚ maintaining‚ and developing an organization’s human resources. Each of the three phases of HRM—acquiring‚ maintaining‚ and developing human resources—consists of a number of related activities. 1. 2. 3. 4. 5. Acquisition includes five separate activities.

today’s world‚ where just about everything is more convenient and accessible due to advances in technology across almost all sectors‚ it may seem as though it’s a misnomer to even mention any disadvantages of technological advances. However‚ despite how far technology has taken humans and no matter how convenient it may make things‚ there are some disadvantages accompanying this level of access. Technology advances show people a more efficient way to do things‚ and these processes get results. For

Algae are simple organisms that typically produce their own food through photo-synthesis. They are similar to higher plants‚ but they lack many of the distinct organs that you will find in a higher plant. The higher plants are believed to have evolved from algae‚ and algae are believed to have gotten their capacity for photosynthesis from cyanobacteria. Algae can be unicellular as well as multi-cellular. Large and complex forms found in the ocean are commonly referred to as seaweed and can look very

Technology is‚ by definition‚ the practical application of knowledge. It is the systematic treatment of art and science. Our new science is circular in its motivation. The proclivity only grows more definite as it kindles consecutively greater aspirations. Perhaps it is a desire‚ whether technical or ethical‚ to leave something here that is greater than before. Now the world is thriving‚ dominated by computers and electronic intelligence that will leave a path for our heir’s advancements into the
