Project - Research Paper Example According to Miles (2008), it involves active acquisition of material items and purchase of services for convenient purposes. This aspect is economic in nature because in entails exercising one’s economic power in purchasing goods and services. On the other hand, consumerism possesses sociological attributes because it serves as a measure of elite lifestyle and social status. Poor members of the society purchase only the basic needs. However, consumerism involves mass acquisition and consumption in excess of one’s basic needs. According to Stearns (2006), consumerism derives its origin from industrial revolution in the Western world. Prior to industrial revolution, resources and goods were scarce, and acquisition of these items was invariably restricted by the scarcity. However, industrial revolution led to massive production of material items and services. As a result of surplus in production, Western societies adopted an economic behavior characterized by massive purc hase and consumption of goods as a show of social and economic strength. Consequently, proliferation of industrialization spread consumerism behaviors to other parts of the world including the Middle East and Asia. In modern commercial settings, consumerism is commonly referred to as consumer culture or market culture. As opposed to its earlier principles of mass consumption, current consumerism entails a close association between brand items and owners. According to Campbell (2005), American markets indicate a tendency for people to elicit strong attraction towards items as symbol of economic and social status. Purchase of brand and expensive automobiles and jewelry satisfies consumerism aspects members within America society. Apart from the US markets, other commercial environments across the world use goods and services as a measure of socioeconomic status of individuals. According to Campbell (2005), this has led to a situation whereby social stratification based on economic str ength has induced irresponsible production and consumption of goods and services. Consequently, irresponsible production presents adverse effects on environment and resource base. Problems of Consumerism Since inception of consumerism as a socioeconomic culture, there have been numerous criticisms on this aspect. Stearns (2006) says that as earlier as during the 20th Century, religious leaders in Europe including Pope Benedict 5 were opposed to the manner in which people were using economic power as a measure of social status. Currently, consumerism has been associated with a myriad of problems which include environmental pollution, depletion of resources, increase in social inequality, disruption of economy and increase in social deviance. With respect to social deviance, people are trying to acquire wealth and resources in an effort to increase their economic

Stability analysis using GUI in MATLAB (Electronic Engineering) Essay

Stability analysis using GUI in MATLAB (Electronic Engineering) Project Proposal - Essay Example Initially it is essential to examine the theoretical basis for the concept of stability in order to identify the various conditions which characterize a stable system. After determining the stability conditions, the Graphical User Interface Development Environment (GUIDE) module of MATLAB will be studied to examine the process of developing a Graphical User Interface for a MATLAB application which determines the stability of a given system. The BIBO (Bounded Input Bounded Output) concept of stability states that if a bounded input to the system produces a bounded output, then the system is stable (Ogata. K. 1997). It is important to determine the physical significance of stability both in the time domain and in the frequency domain. In the time domain, for continuous functions to be BIBO stable, an integral of their impulse response should exist. Similarly for discrete functions in the time domain, we should be able to sum up the impulse responses of the discrete function (Ogata. K. 1995). To determine stability in the frequency domain, we consider the Laplace transform (used for converting continous functions from time domain to frequency domain and vice versa) for the continous signals and Z transform (used for converting discrete functions from time domain to frequency domain and vice versa) for the discrete signals. If the region of convergence of the Laplace transform includes the imaginary axis, then the system i s stable (Ogata. K. 1995). The physical significance of this statement is that all poles of the system should on the left of the origin (as we are dealing only with causal systems). If the region of convergence Z transform includes the unit circle then the system is stable. A system is stable if and only if all its poles are lying within the unit circle. The transfer function is an illustration of the relationship between the input to a system and the output of the system (Ogata. K. 1997). It accurately represents a system which is time invariant
