Monitoring of the biopotential signals in present scenario attract much attention to the researcher due to increasing demand for better quality of life and to enhance interaction between humans and machines. Biopotential signals are relatively weak amplitude and low frequency in nature. Therefore it is required to design a front circuitry that defines quality of signal for processing to the nex...

Synchronous relational interfaces is an interface theory which allows to specify the I/O interface of a component with input requirements and relational input-output guarantees. The theory allows to check interface compatibility during composition and to compute a composite interface from the atomic ones. It provides a refinement operator which allows to check whether a component can safely rep...

Tremendous amount of images are used on modern Web pages, but images are rarely used in everyday communication via e-mail, SMS, SNS, etc., although many communication systems allow the use of images in the message. We believe that images can greatly enhance the quality of communication if they are appropriately used with alphabetical texts, and we created a text input system with which users ca...

In this work, an input-powered AC/DC CMOS bridge rectifier (CBR) is proposed using 0.18 μm CMOS process. It is based on a simple bridge connected full wave rectifier, without an external dc voltage to turn-ON. The rectifier may be used for energy harvesting applications with a typical output of relatively low-amplitude input and low frequency of ac voltages. The proposed CBR achieves a maximum ...

Design of Global Positioning System (GPS) receiver with a low noise amplifier (LNA) in the front end remains a major design requirement for the success of modern day navigation and communication system. Any LNA is expected to meet the requirements like its ability to add the least amount of noise while providing sufficient gain, perfect input and output matching, and high linearity. However, mo...

in order to evaluate the effect of different crop management practices on corn (zea mays l.) net primary productivity (npp) and relative carbon allocation coefficients, a field experiment was conducted based on a completely randomized block design with four replications in the agricultural research station, ferdowsi university of mashhad, iran during two growing season 2008-2009 and 2009-2010. ...

We certify that this work has passed the scholastic standards requested by the Information and Communications University as a thesis for the Abstract The commercialization of Ultra-WideBand (UWB) ranging from 3.1-10.6 GHz by Federal Communication Commission (FCC) has recently emerged as a promising technology for short-range wireless data communications. The applications of wireless data commun...

The design specification method described in this report treats a software architecture as a set of runtime entities, including tasks and external input/output elements, which interact either via messages or shared data structures. Tasks have a single thread of execution and represent program units that may be executed concurrently. External input elements produce input requests that in turn tr...
