MICROCONTROLLER BASED MULTIPLE DEVICE CONTROL BASED ON INPUT FREQUENCY.
DESCRIPTION:
The 230v ac supply is down converted into 12v by ac transformer. The transformer output is rectified by bridge rectifier and converts into pulsating dc. This voltage is given to the filter. The filter removes the unwanted ripple components and outp ....etc

ABSTRACT

In this paper a new single phase to three-phase converter for ac motor is proposed. The proposed converter employs only six switches and incorporates active input current haping feature, which results in sinusoidal input current at close to unity power factor. The front-end rectifier in the proposed converter permits bidirectional power flow and therefore provides for excellent regulation against fluctuations in source voltage. This feature also facilitates regenerative braking of ac motor drive. An easy to implement control stra ....etc

The dream of every communication designer is to provide good quality service to each of his customer within the limited available bandwidth. But in the recent years, the amount of data flowing through the channel has increased. But there has been no such high increase in the available bandwidth. So it is a challenge to effectively utilize the channel spectrum along with providing good quality of service across wireless links. One of the possible ways is to use multiple antennas at both the ends of the transmission link. MIMP exploits natural ph ....etc

This article presents a class which can be used in both the client and server code. The class uses IOCP (Input Output Completion Ports) and asynchronous (non-blocking) function calls which are explained later

With this simple report you could understood :

Service or connect to multiple clients and servers.

Send or receive files asynchronously.

Create and manage a logical worker thread pool to process heavier client/server requests or computations.

It is difficult to find a comprehensive but simple source code to handle client/se ....etc

A Multiple-Input Dc-Dc Positive Buck-Boost Converter Topology

Abstract-
A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltage-current characteristics, while achieving low part number and bi-directional operational. Compare to previous multiple-input buck-boost converter, the proposed topology provides positive output voltage; it is capable of bi-directional operation; and it has the capability of operating in buck, boost, and buc ....etc

Abstruct-
Analysis, design, and implementation of the space vector modulated three-phase to three-phase matrix converter with input power factor correction are presented. The majority of published research results on the matrix converter control is given an overview, and the one, which employs sheous output-voltage and input-current space vector modulation, is systematically reviewed. The modulation algorithm is theoretically derived from the desired average transfer functions, using the indirect transfer function approach. ....etc

Abstract

present Skinput, a technology that appropriates the human body for acoustic transmission, allowing the skin to be used as an input surface. In particular, we resolve the location of finger taps on the arm and hand by analyzing mechanical vibrations that propagate through the body. We collect these signals using a novel array of sensors worn as an armband. This approach provides an always available, naturally portable, and on-body finger input system. We assess the capabilities, accuracy and limitations of our technique t ....etc

Abstract

Magnetic servo levitation (MSL) is currently being investigated as an alternative to drive fast-tool servo systems that could overcome the range limitations inherent to piezoelectric driven devices while operating over a wide bandwidth. To control such systems, a feedback-linearized controller coupled with a Kalman filter has been previously described. Performance limitations that degrade tracking accuracy suggest the use of a more robust controller design approach, such as sliding-mode control. Current literature on slidi ....etc
