Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc

The signal monitor does the work of the backend monitoring when you have a test setup going. In instances where a preamplifier is under test, the signal monitor acts as the convenient block because it has its own internal speaker.All youâ„¢re going to need from the signal monitor output is again some audio indication whether or not the circuit
under test is functioning.

Circuit Description
Figure shows the electrical schematic for the signal monitor. The trusty LM 386 (IC1) audio power amplifier is going to be used as our driving IC he ....etc

Fire Monitor
This project Fire Monitor is used to monitor the Temperature of two Rooms and if the sensor found any fire in the Room then the alarm will be switched ON until the Fire is put off else the Reset button is pressed. The Fire was sensed by using the Thermistor. The Thermistor is a passive device which has a Negative Temperature Co-efficient (NTC), i.e when the temperature increases then the resistance of the Thermistor will decrease. A analog comparator is used for the fire sensor circuit , at normal temperature the output of the com ....etc

Abstract
This project monitor activates in a Local Area Network and gathers useful information about host machine as well as other nodes in the network. This project includes implementation of ping and uses ping to monitor various activities. It displays live nodes in the network. Prints network connections, routing tables, interface statistics,arp table ,subnet mask etc.It also displays IP and MAC address of any node given it's hostname. Time status is also displayed. It has a very good graphical interface so that network information is acce ....etc

TOUCH SCREEN MONITORS
SEMINAR ON TOUCH SCREEN MONITORS
Introduction
A touch screen is an easy to use input device that allows users to control PC software and DVD video by touching the display screen. A touch screen can be used with most PC systems as easily as other input devices such as track balls or touch pads.
Why Touch Technology
Touch screens enable people to use computers instantly, without any training whatsoever.
Touch screens virtually eliminate operator errors because users select from clearly defined menus.
Touch scree ....etc
