Sean Braun Assignment 9 There are two main types of fibre optic transmitter that are in use today. Both of them are based around semiconductor technology: • Light emitting diodes (LEDs) • Laser diodes Semiconductor optical transmitters have many advantages. They are small‚ convenient‚ and reliable. However‚ the two different types of fibre optic transmitter have very different properties and they tend to be used in widely different applications. LED transmitters These fibre optic transmitters

Importance of negative feedback Negative feedback is when a departure from a norm initiates changes which restore a system to the norm. The first example of the importance of negative feedback is in control of the heart rate. The heart is myogenic‚ meaning that each heartbeat is initiated by sinoatrial node inside the heart itself‚ not by nerve impulses from the central nervous system. After exercise‚ the concentration of carbon dioxide in the blood is high‚ meaning that the pH in the blood is

The role of 360-degree feedback in performance appraisals How does this compare with other performance appraisal methods? Executive summary 360-degree feedback is one of the most widely used employee assessments today. Its popularity has increased dramatically with the growth of the web-based assessment tools that has made implementation easier‚ cheaper and faster. The purpose of the 360-degree feedback is to assist each individual to understand the strengths‚ weaknesses and development needs

Information Systems Architecture and Technology | Feedback Loops and Information Systems Feedback loops are a part of the systems we examine in systems thinking. Our first text book Thinking in Systems tells us we can see the existence of a feedback loop when “the consistent behavior pattern over a long period of time” is observed. My own interpretation is that feedback loops provide information in real time (or something close to real time) to provide the opportunity to make adjustments

Constructive Feedback Job Aid Use this job aid the next time you are asked to give or receive feedback. Refer to it to help you recall concepts from the tutorial. What Is the Purpose of Feedback? • Receiving feedback helps a writer become less attached to his or her work. • Giving feedback helps a reviewer practice analytical skills: o Criticize and examine work o Question errors o Suggest improvements How Do I Give Feedback? Peer review is a method for giving and receiving feedback:

How feedbacks help a team As a member in the group‚ it is important to give feedbacks to others which will increase the effectiveness within the teamwork. What the article tells me is that how to improve the word choice for feedbacks in order to avoid the negative consequences. By using the descriptive words instead of evaluative ones‚ useless anger toward others can be avoided. For instance‚ by point out the problems one have in doing certain task is much better than categorize the person. Furthermore

which the body can respond to changes‚ these being positive and negative feedback. Negative Feedback Negative feedback causes the body to respond in such a way as to reverse the direction of a change and this tends to keep the internal environment at a constant‚ thus maintaining homeostasis. Sensors and receptors are what bring about a reaction to ensure conditions within the body remain favourable. Examples of negative feedback are as follows. Blood glucose levels The receptors of the pancreas are

Negative feedback in living organisms Negative feedback is a principle which is used by the body in order to return systems to its normal level; it does this by turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal environment. There are a number of different examples of negative feedback such as thermoregulation‚ regulation of blood glucose and the regulation of water potential. The control of the heartbeat can also use
