In Communication system, the system capacity and performance are adversely affected and degraded by interference. Hence, power control plays a prominent role in an interference-limited system, which increases the efficiency by mitigating the adjacent and co-Channel interference in the system. In this paper, primarily power control is said to be used in maintaining the acceptable Carrier to Interference Ratio (CIR) by meeting some Quality of service (QoS) requirements Objective function that is defined as maximum channel capacity in a power constraint scenario. The signals in a radio channel undergo different propagation effects like reflection, refraction, scattering and shadowing. Hence, the distribution of users across subcarrier groups as well as their transmission powers within a given cell has a significant effect on how users and power are accordingly distributed elsewhere in the network to maximize the capacity of the system thereby enhancing its performance
Multi-attribute analysis is a useful tool in many economical, managerial, constructional, etc., problems. There is usually some uncertainty involved in all multi-attribute model inputs. The objective of this work is to demonstrate how simulation can be used to reflect fuzzy inputs, which allows more complete interpretation of model results. A case study is used to demonstrate the concept of general contractor choice of on the basis of multiple attributes of efficiency with fuzzy inputs applying COPRAS method. The work has concluded that the COPRAS method is appropriate to use.
Clustering technique is the basic technique used in the wireless sensor network to enhance the lifetime of a sensor network by mitigating energy consumption and provide efficiency, scalability, and security. Formerly sensor nodes are considered to be homogeneous in which each node has the same processing capacity, energy and functionality, but to prolong network lifetime researches has been evolved to infuse heterogeneity in wireless sensor network such as to provide different energy level to some nodes. In this paper, we present a survey on basic clustering techniques for Heterogeneous wireless sensor networks.
Cooling tower is an important part of power plant. The efficiency of power plant is directly depends on the effectiveness of cooling tower. In cooling tower scheduled maintenance and shutdown maintenance is a problem which affects its effectiveness and performance of cooling tower. In cooling tower shutdown maintenance required in every 2 to 3 year periods at this period the whole plant will be shutdown, and require 28 to 35 days maintenance so that cooling tower will be in its best working condition. In every cooling tower manufacturer provide the scheduled maintenance check list so that the worker will perform their maintenance as per given instruction. In present work optimization of shutdown maintenance strategy is done so that the time elapsed in maintenance will reduce and the requirement of man power will be reduced.
When you drive a car that is old, you will need to take extra care regarding the maintenance schedules. If the vehicle’s fuel efficiency is not up to the mark, you should take special efforts to make it better. Here are few things that you should not forget to do if your car is a bit old.
Eversince its inception, bitcoins have been used in different ways and for different purposes. From personal to business transactions, with its lower transaction costs and efficiency, many opt to use bitcoins. As an open-source payment platform, it allows greater flexibility when it comes to usage.
These are common in France too and if you are business owner looking to get new electric hot water heaters installed at your place, Clients also get value added service such as hot water tank installation when buying a water heater from these leading firms.
Organizations today have increasingly become aware of the importance of strategic Human Resource Management (SHRM). This awareness in a system is a critical dimension in the performance of organizations. Most organizations today are undergoing some structural, operational, and business strategic changes with the aim of improving their performance. The organization‟s competitive strategy may include mergers and acquisitions, downsizing to increase efficiency, internal operations, or the acquisition of automated production technology. These strategic decisions determine the demand for skills and human resource. Incompetent and unbalanced: resourcing, training, development, reward, and appraisal methods have led to poor performance. The seminar sought to establish what other researchers have done in the field of human resource and performance of organization.
