Abstract

Objective: The idea is to upload files into cloud using gestures. A “Gesture” is a form of movement of part of a body, especially the hand or the head, to express an action. Waving of the hand over the phone is used as a gesture to export files into the cloud. Methods/Analysis: The type of the file to be uploaded into the cloud can be either a picture or a video. This is accomplished using an application similar to gallery. To perform the task, the application is invoked to view a picture or video, when the hand is waved over the phone. The gesture is recognized and the currently viewed file is uploaded into the cloud. The cloud service used here for uploading is Dropbox. The size of the media files is generally large and uploading it will take time, so the size is reduced through a compression algorithm. There is a buffer which tracks the uploading part and will see to that, that the entire media file is uploaded into the cloud. Findings: Through this application the file can be uploaded into the cloud through a gesture easily and effectively. Also, it is found that the application developed is found to be stable in tough testing conditions. Application/Improvements: This app reduces the human effort to a large scale and most importantly it does not occupy more space in the handheld device.The same app can be further ported to IOS for apple phones and IPads.

Abstract

A reconfigurable antenna built on E-shaped structure with an ability to control bandwidth is discussed in this proposed work. To configure antenna automatic or manual tuning is done so that they can accustom to the varying system requirements thus can avoid those limitation and offers extra functionality. A frequency reconfigurable E-shaped patch antenna can be utilized for improving the bandwidth.The bandwidth can cover the frequency range from 1.85 GHz-2.33 GHz. The enactments of the offered antenna, in terms of reflection losses and radiation patterns, with divergent DC bias voltages is analyzed using a varactor diode. A broad research was taken over to analyze the nature of the antenna at different frequency.

Keywords

Abstract

Objective: The Ultimate aim of the VLSI Design is to improve the efficiency, Reduction of Delay and Power Consumption and to minimize the area. In our proposed approach we had implemented the analysis had been done on the field of Speed, Power consumption, Area and Power delay product (PDP) for a carry skip adder with other adders listed as the parallel prefix adders and others. Methods/Statistical Analysis: The Carry-Skip Adder planned here reduces the time required to propagate the carry by skipping over teams of consecutive adder stages, is understood to be comparable in speed to the carry look-ahead technique whereas it uses less logic space and fewer power. Findings: The adders are basic building blocks of the digital circuits for the Signal processing, Integrating and other process of operation. There are various types of adders are proposed in Literature which are commonly used in VLSI Design. The Simulation results also shows that the proposed adder Architecture is Faster and Area efficient compared to other existing adder architecture. Application/ Improvements: They estimate the performance of proposed design will be better in terms of Logic and route delay by experimental results.
