Perimeter Security and Predator Control Device

Intrusions can be very unlikable and often times cause property loss which in turn can cause great dissatisfaction. It is this continuing dissatisfaction from predators on various kinds of properties that led us to take protective action.
 This project will spotlight chiefly based on detection systems, intimidation tactics, as well as logging intrusions. It is intended to establish a preventive system and deliver a product which will permit the client the capability to efficiently examine, and daunt predators from his/her property.

Circuit Placement with Multi-Core Processors

Circuit placement is the runtime bottleneck in the VLSI design flow. A faster placement tool would be very precious because it helps circuit designers to reduce the design time. This project presents the use of mutli-core processors to accelerate circuit placement. A multi-thread implementation of a sequence placement algorithm will be developed and tested on a multi-core system

FPGA-based NES Emulator

This project is based on showing emulation capabilities of reconfigurable hardware. Therefore, it has undertaken the job of understanding the original Nintendo Entertainment System (NES) design, and emulating the original processor and peripheral interface hardware. Given that the original NES design is well understood and documented in the emulation community, and that software based emulators handle full NES functionality, it is expected that a fully working FPGA-based emulation is sufficient in a two-semester time period.

Asynchronous Wrapper for Globally Asynchronous Locally Synchronous Systems

The new globally asynchronous locally synchronous (GALS) technology for integrated circuits is been investigated.A new wrapper design is presented by testing different types of asynchronous wrappers . It also investigates the possibility to use VHDL for asynchronous simulation and synthesis. The conclusions are that the GALS technology is possible to use but that it needs new synthesis tools, because todays tools are designed for synchronous technology.

Hybrid Electric Vehicles (HEV) (Clean & Fuel Saving Technology)

Today automobiles are identified as one of the major causes of air pollution and energy depletion. Vehicles are also identified for their low efficiency in other words high-energy loss. Hybrid Electric Vehicles have the capacity to overcome these situations and bring a new revolution.
Any vehicle that combines two or more sources of power that can directly or indirectly provides propulsion power is a hybrid. The gasoline electric hybrid vehicle is just the required type of crossbreed between a gasoline powered vehicle and electric vehicle. Hybrid vehicles run both with a rechargeable battery as well as gasoline. In a hybrid engine, power from gasoline and power from a set of batteries transmits power to an electric motor. There are less adverse effects due to the Hybrid electric vehicles. Also the batteries used in hybrid vehicles (rechargeable Nickel metal hydride, Lead acid batteries, Lithium Polymer batteries) are disposable which will not pose any toxic hazards to the environment. The notable fact in hybrid vehicles is that the DC machine is that it can run both as a Motor as well as a generator.
In addition, hybrid vehicles make use of a system that recovers power from the momentum of the vehicle when braking. The Hybrid vehicles are complicated machines when compared to their counterparts of the gasoline-powered vehicles. But higher efficiencies, lower emissions of hybrid vehicles grabs the attention of the new ERA. The other facilities of these hybrid vehicles i.e. performance, manufacturing cost and environmental impacts are discussed in this paper.

Vehicle Skid Control

Vehicle skid can be defined as the loss of traction between a vehicle’s tyres and the road surface due to the forces acting on the vehicle. Most skids are caused by driver error, although only about 15% of accidents are the direct result of a vehicle skidding. Skids occurring in other accidents are usually the result of last minute action, by the driver, when faced with a crisis ahead rather than actually causing an accident. Skids can occur both in the dry and wet as well as icy conditions, however, the chances of losing control and having an accident increases by 50% in the wet. The most common type of skid we will be confronted with is when the rear end of the car slides out, causing an oversteer or when the front of the car plows toward the outside of a turn without following the curve of the turn causing an understeer. Usually, oversteer occurs as a result of going into a corner too fast or incorrectly hitting a slick area, causing the rear wheels to oversteer. A third skid called the four wheel skid can also occur, where all the four wheels lock up and the vehicle slides in the direction where the forward momentum is carrying it, with no directional control.

Compressive Strength Characteristics Of Stacked Stabilized Soil Cement Blocks

Soil degradations one of the weakness and global threats these days both for agricultural production and food security, but also for the environmental challenges associated to watershed protection, disaster management, bio-diversity conservation, sustainable management of natural resources and climate change, furthermore, complication in Civil engineering. In Bangladesh where arable lands are certainly vulnerable to severe erosion due to rainfall and flood, particularly when poor agricultural methods are used or preventive measures are not taken. Implementation of Jute Geotextiles (JGT) aided by native vegetation cover was investigated intended to design a sustainable and low cost tactic at Beel Dakatia through the entire year of 2009. Prime consequences were that erosion, moisture content and runoff are likely to be considerably impacted by rainfall intensity, soil surface slope; additionally, combined presence of JGT and vegetation cover reduced rate of erosion about 95% and runoff about 70% with respect to bare plots. Hence, play noteworthy role to conserve soil and stabilize the slope as well and mitigate susceptibility to degradation

Training Report on Efficient Transportation

The energy, environmental and social benefits of sustainable transportation have always been recognised but are now mainstream as Kyoto and the community politics of transportation indicate. However sustainable transportation has always been seen as secondary in economic terms unless lots of unquantifiable parameters were included. The results of a study for the World Bank now show that cities with significant sustainable transportation systems are least costly in terms of a range of parameters including the amount of road expenditure, transit operating cost recovery, fuel-efficiency, road accidents, air pollution and in overall terms the % of city wealth that goes into transportation. The data show that cities with the most roads hare the most costs for their transportation and the most rail-oriented cities have the least transportation costs. Further, the single most important variable relating to transportation efficiency is the density of the city - the most sprawling cities are the most costly. Thus strategies to contain sprawl, to reurbanise , to traffic calm, to build new light rail systems into car dependent suburbs with focused sub centers, and to facilitate biking and walking, all appear to add to the economy of a city. Strategies that build freeways and add to sprawl are draining the economy of cities. Global information trends are making the need for these sustainable urban patterns even more necessary. The need to  operationalise these strategies in planning and engineering practice and in the politics of infrastructure funding remain the major challenges.
