WHAT IS A SMART DUST?

Autonomous sensing and communication in a cubic millimeter

Berkeleyâ„¢s Smart Dust project, led by Professors Pister and Kahn, explores the limits on size and power consumption in autonomous sensor nodes. Size reduction is paramount, to make the nodes as inexpensive and easy-to-deploy as possible. The research team is confident that they can incorporate the requisite sensing, communication, and computing hardware, along with a power supply, in a volume no more than a few cubic millimeters, while still achieving ....etc

ABSTRACT
The overall goal of the work presented in this thesis is to extend the physical understanding of the external aerodynamics associated with the rotating case of Hovering Rotor using Computational Fluid Dynamics (CFD) technique.
Rotating blades encounter tip vortices coming from preceding blades, which results in Blade Vortex Interaction(BVI) responsible for producing dynamic effects. Understanding the complex flow field due to this dynamic effects produced by wakes is therefore very important for the prediction of effects such as blad ....etc

Here is a sleep-switch circuit that can be easily converted into a wake-up timer. A dual-mode time setting makes the system versatile. The circuit is low-cost and can function as a precise timer. The heartbeat produced by IC1 is a sharp 1Hz square wave signal having a duty cycle of 50 per cent. This is achieved by using a 4.194304MHz crystal in combination with discrete components around it. The 1Hz output of IC1 is connected to IC2 as well as one of the terminals of switch S1. IC2 is configured as divideby- 6 counter while IC3 further divides ....etc

Minimizing Delay and Maximizing Lifetime forWireless Sensor Networks With Anycast
Abstract
In this paper, we are interested in minimizing thedelay and maximizing the lifetime of event-driven wireless sensornetworks for which events occur infrequently. In such systems,most of the energy is consumed when the radios are on, waitingfor a packet to arrive. Sleep–wake scheduling is an effective mechanismto prolong the lifetime of these energy-constrained wirelesssensor networks. However, sleep–wake scheduling could result insubstantia ....etc

Now a days the wireless technologies are more in use and are widely evolving. Some of the technologies now in use are Wi-Fi, Wi-max, Zigbee, Bluetooth¦¦. Out of which Bluetooth is most popular. These technologies are widely used to connect the large devices like mobile phones or personal computers. No other existing wireless technologies will connect with small button cell battery devices so effectively. So the Nokia introduced the new radio technology called Wibree.

ABSTRACT
Advances in hardware technology has enabled very compact, autonomous and mobile nodes each having one or more sensors, computation and communication capabilities ,and a power supply. The Smart Dust project is exploring whether an autonomous sensing, computing, and communication system can be packed into a cubic-millimeter mote to form the basis of integrated, massively distributed sensor networks. It focuses on reduction of power consumption, size and cost. To build these small sensors, processors, communication de ....etc

ABSTRACT





A torpedo is self propelled under water missiles with its own guidance system. They are also used as parts of other weapons. It is designed to detonate on contact or in proximity to a target. The torpedoes used against submarines are shorter and lighter .The main types of torpedoes used in U.S navy are MARK 46, MARK 48, and MARK 50.
In my topic, I would like to give a brief description on torpedoes, its working and its feat ....etc
