Speed Control of Parallel Connected DSIM Fed by Six Phase Inverter with IFOC Strategy Using ANFIS

This paper describe the presentation of an IM for high load and high-power applications, this kind of applications the motor have a complex coupling between the field and torque. This can be achieve with assist of Indirect Field Oriented Control (IFOC) and parallel connection of two motors. The benefit is that parallel connection can provide the decoupled control of flux and torque for each motor and their concert in different operating environments. The Speed control of two Double Star Induction Motors working in parallel configuration with IFOC using a Fuzzy Logic Controller (FLC) and Adaptive Neuro Fuzzy Inference (ANFIS) controller is investigate in different operating environments. The two motors are connected in parallel at the output of a single six-phase PWM based inverter fed from a DC source. Performance of the projected method under load disturbances is studied through simulation using a MATLAB and evaluation of speed response of two controllers is analyzed. &nbsp

Improving Quality of Lead Data of Customer Relationship Management in M-Commerce

Abstract: In the present growing trend of mobile computing, technologies, applications mainly focus on mobile ecommerce (m-commerce) and the mobile Web. As the mobile commerce market grows, Customer relationship management (CRM) is one of the major applications that incorporates the present marketing standard of relationship management (RM) and supports in acquisition, understanding requirements, and maintaining long-term relationships with customers. Expanding the CRM applications to mobile devices is increasingly becoming a major goal for organizations to optimize their workforce. To obtain a successful and desired outcome, quality of acquired data has a major impact on the organization's productivity. Hence the quality of data constitute the basis for major decisions of organization's operational and strategic levels which intern leads to positive growth of organizations. In order to tackle the above issue, we have proposed a novel quality model for customer lead data. Some of the activities are defined to analyse the performance of system with respect to time, data quality, reliability. This framework needs a feasible implementation module in the near future for improving quality of CRM lead data in m-commerce

DESIGN OF AIR CONDITIONING SYSTEM IN AUTOMOBILE

Abstract: Transportation is one the need of human being, which is existing since the evolution of mankind. Today, the field of air conditioning design is more technologically challenging than ever before. In the present the design of air conditioning is done for a Volvo bus, a fully equipped automotive air-conditioning system consists of five main components: a compressor, a condenser, an orifice tube, an evaporator and an accumulator. R-134a is used as refrigerant by considering the various parameters

Modeling and Control of a Permanent Magnet Synchronous Generator Wind Turbine with Energy Storage

Wind energy is an important renewable source which is used for power generation for a stand-alone as well as grid connected applications. In many remote areas, loads are usually connected away from the grid. In such cases, isolated wind energy systems can be considered as an effective way to provide continuous power to electrical loads. The power conversion unit features a windturbine-driven PMSG, a di od e rectifier, a b uc k converter, a battery bank, a feed-back controller, and a dc/ac inverter. In this paper, an isolated wind energy conversion system is implemented using a variable speed permanent magnet synchronous generator (PMSG) with PWM rectifier and a battery for storing the excess amount of wind energy. To change the duty cycle of the converter, a controller of DC-DC buck converter with MOSFET as a switching component is designed using P, PI and PID controller to provide the efficient choice for the selection of the controller. The proposed scheme is implemented in MATLAB using Simulink & the simulation results show that the output voltage of the converter can be controlled according to the value of duty cycle and the excess power is stored in battery to provide balance between the generator and the load.

GENERIC LOSSLESS VISIBLE WATERMARKING BY USING TRANSLUCENT AND MONOCHROME METHOD

Images make up a major component of multimedia content. Digital arts, illustrative diagrams, cultural heritage paintings in digitized for and digital photographs are examples of images. Advances in computing hardware, software, and computer networks have created threats to copyright protection and content integrity. In this paper, a new method for lossless visible watermarking is proposed by using appropriate compound mappings that allow mapped values to be controllable. The mappings are proved to be reversible for lossless recovery of the original image. The approach is generic, leading to the possibility of embedding different types of visible watermarks into cover images. Two applications of the proposed method are demonstrated, where opaque monochrome watermarks and non uniformly translucent full-color ones are respectively embedded into color images
