Submitted By: Syed Ahsan Ali Bokhari Introduction:Our aim is to develop a stochastic model of sensor networks where each sensor node is taken randomly and one after the other in sleep and active state. After analysis of the sensor model‚ we try to formulate the probability when there are many data packets in many sensor nodes. The model is analyzed in terms of energy usage‚ delay in average data and efficiency. With the increasing trend towards wireless‚ WSNs are becoming popular due to their use

What is Scientific Research Process? There were so many researches that had been run‚ are running and going to run in the future. However‚ what is a research after all? Research means to search for knowledge‚ to make a systematic investigation or to establish novel facts (Trochim‚ 2006). According to Sekaran and Bougie (2010)‚ research is defined as simply the process of finding solutions to a problem after a thorough study and analysis of the situational factors. The definition of research includes

H-beta zeolite was studied using the ONIOM approach with two proposed reaction paths: stepwise and concerted mechanisms. The results obtained by the ONIOM2 (B3LYP/6-31G(d‚p):UFF) method reveals that the tert-butylation of phenol preferentially occurs through a co-adsorbed‚ concerted mechanism without prior dehydration of tert-butyl alcohol‚ rather than via a stepwise mechanism through dehydration to form tert-butyl carbenium ion as the first step followed by tert-butyl cation attack on the 2- or 4-position

Chapter 7: managing flow variability: safety inventory 7.1 Objective In the previous chapter on inventory‚ we focused on economies of scale as the major driver for inventory. The purpose of this chapter is to introduce the notion of safety inventory as a buffer against stochastic variability in supply / demand and discuss various levers for reducing it. The chapter is covered over two classes each of duration 100 minutes. In the first class‚ we first motivate the need for forecasting as a way

chances of catching the flu. The first tip is going to be something that every person should be doing no matter what time of year it is. Wash your hands. According to the Mayo Clinic Staff “Frequent hand washing is one of the best ways to avoid getting sick and spreading illness.” Although hand washing is by far one of the best ways to prevent spreading bacteria you can also use alcohol based hand sanitizers. These hand sanitizers require no soap or water you just rub it on and then it dries. These

Medicalization describes a process by which a non-medical problem becomes defined and treated as a medical problem‚ usually in terms of illness and disorders. Medicalization used to be focused on deviance‚ now it focuses on a range of human problems. Medicalization is increasing as technology advances. There are many things that have become medicalized such as Alcoholism‚ mental disorders‚ eating disorders‚ sexual dysfunction‚ etc. There are three degrees of medicalization. 1. Fully medicalized‚

develop theories of aging for centuries‚ and neither of them has been accepted. There are two main categories of aging theories‚ such as programmed theories and damage theories. Programmed theories say that life expectancy is genetically (present passive)predestined. According to the Hayflick Limit Theory‚ humans cells stop functioning and then die ( participial phrase) after dividing about fifty to sixty times. Damage theories say that damage to our cells is responsible for aging. Cells accumulate

What the believer does during hajj is to recall what happened to important persons in Muslim history. The rituals performed around the Ka’ba recalls the acts of Abraham and Isma’il when they turned the Ka’ba into the sacred place of worship and peace (Koran sura 2 aya 119).
