The Cost of Noise Reduction in Helicopters
The relationship between noise reduction and direct operating cost was studied for transport helicopters. A large number of helicopter preliminary designs was generated with the help of a computer program. Vehicles were selected to meet certain noise goals with minimum direct operating cast. this was repeated for several payloads and technology time frames. The effect of changes in the assumed ...
متن کاملScheduling of Residential Multiclass Appliances in Smart Homes UsingV2H Capability of Electric Vehicle
With the aim of reducing cost of electricity consumption and peak load reduction, tools requirement for better managing electricity consumption have become inevitable in recent years. Smart home has some equipment which are controllable and this ability is used for increasing comfort and minimizing electricity cost for residence. As a key component of smart home , Electric Vehicle(EV) ,increase...
متن کاملCost and Environmental Pollution Reduction Based on Scheduling of Power Plants and Plug-in Hybrid Electric Vehicles
There has been a global effort to reduce the amount of greenhouse gas emissions. In an electric resource scheduling, emission dispatch and load economic dispatch problems should be considered. Using renewable energy resources (RESs), especially wind and solar, can be effective in cutting back emissions associated with power system. Further, the application of electric vehicles (EV) capable of b...
متن کاملEvaluation of Noise Pollution in Small Workshops in Qom, Iran; and Its Situation Compared to National Noise Standards
Background & Aims of the Study: Noise is one of the most important environmental pollutants. It is a global health problem, especially among industrial workers. Since there was little information about noise levels in small workshops in Qom city, this study aimed to evaluate noise in small workshops and compare it with national standards. Materials and Methods: This was a cross-sectional stu...
متن کاملShearlet-Based Adaptive Noise Reduction in CT Images
The noise in reconstructed slices of X-ray Computed Tomography (CT) is of unknown distribution, non-stationary, oriented and difficult to distinguish from main structural information. This requires the development of special post-processing methods based on the local statistical evaluation of the noise component. This paper presents an adaptive method of reducing noise in CT images employing th...
