To achieve higher economy of the original driving scheme with single motor and settled gear ratio, new configurations with different powertrain systems in front and rear axle were designed. Firstly, according to the power and torque required by a micro electric vehicle (mEV) in various drive cycles, the parameters of a small and high power motor were determined. Secondly, for schemeⅠwith dual m...

present paper investigates the numerical solution of two-dimensional unsteady compressible navier-stokes equations by a new scheme based on the finite volume method. kinetic energy preserving (kep) scheme is introduced for solving the supersonic and transonic external compressible flow field on very fine grids (with a number of cells of the order of the reynolds number) without artificial dissi...

Decision making process in agriculture is fundamentally concerned with achieving integrated, productive and sustainable use of financial, biological and social capital at different levels. As our understanding and knowledge of the environmental and production resource base has improved, the need for integrated approaches to management has been more widely appreciated. The intensification of agr...

A new guidance scheme for the problem of Low-thrust transfer between inclined orbits is developed within the framework of optimal control theory. The objective of the guidance scheme is to provide the appropriate thrust steering program that will transfer the vehicle from an inclined low earth orbits to the high earth orbits. The presented guidance scheme is determined using Pontryagin’s princi...

Recognition and classification of Power Quality Distorted Signals (PQDSs) in power systems is an essential duty. One of the noteworthy issues in Power Quality Analysis (PQA) is identification of distorted signals using an efficient scheme. This paper recommends a Time–Frequency Analysis (TFA), for extracting features, so-called "hybrid approach", using incorporation of Multi Resolution Analysis...

Purpose: The purpose of the paper was to identify process spatial planning and highlight its role in sustainable urban development restitution agriculture. By reviewing French solutions this area, an attempt made indicate importance agriculture shaping (SD) metropolitan areas. Design/Methodology/Approach: In order illuminate phenomenon strategic agriculture, a descriptive case study adopted as ...

Precision agriculture encompasses automation and application of a wide range information technology devices to improve farm output. In this environment, smart collect exchange massive number messages with other servers over public channels. Consequently, farming is exposed diverse attacks, which can have serious consequences since the sensed data are normally processed help determine agricultur...

Agriculture provides economic opportunity through innovation; helps rural America to thrive; promotes agricultural production that better nourishes Americans; and aims to preserve natural resources through healthy private working lands, conservation, improved watersheds, and restored forests. From agricultural production to food supply, agriculture supports rural and urban economies across the ...
