This paper proposed an embedded HW/SW implementation for the computing system of a small scale without human autonomous sailing boat. The system is integrated in a mono XILINX FPGA, and hosts a Microblaze soft processor surrounded with mixed, custom designed, control and processing modules than handle the interface with all the sensors, actuators and communication devices of the sailing boat. These interfacing modules implement tasks that have been decentralized from the master processor, thus alleviating its computational load and providing processing time for upper level software applications. Using FPGA to implement an integrated single-chip computing system, as an alternative to conventional processors, has proven to be a very flexible solution as it eases the migration of computation tasks between the hardware and software domains, and more importantly, allowing the rapid adaptation of the digital interfacing hardware in order to support additional peripheral devices required for an application mission. The software component of the boat’s control system runs on the top of the uClinux embedded operating system and is formed by various concurrent applications developed in C with the standard Linux libraries. Remote monitoring, configuration and operation of the sailing boat is done via a WiFi link, using a graphics interactive application that runs on a conventional PC. For this paper reference of paper "An FPGA-based Embedded System for a Sailing Robot" by José C. Alves and Nuno A. Cruz from Faculty of Engineering University of Porto Porto, Portugal is been taken.

In current years, growth of load demand rises day by day, but this growth does not ensue the same in equipment’s of power systems and therefore operators have to use supreme available capacity of systems to fulfill load demands. These activities make power systems so unpredictable. One of best ways to develop reliability of systems is using FACTS devices. In this project the voltage sag occurred during overloading condition is observed and it can be mitigated by using STATCOM. FACTS devices can regulate the reactive and active power control as well as adaptive control of voltage-magnitude instantaneously because of their fast control characteristics and flexibility. Placement of these devices in appropriate location can lead to maintain bus voltages in preferred level and control in line flow and so increase voltage stability margins.

Information dissemination in pure Vehicular Ad hoc NETworks (VANET) becomes problematic when the network is sparse. This is certainly the case in the early years of market introduction, because of the low market penetration. Moreover, in rural areas or during night-time the vehicular network can become sparse due to low traffic density. Sparse vehicular networks become fragmented, resulting in disconnected clusters of vehicles due to the limited communication range of Car-to-Car (C2C) technology. These inherent VANET characteristics such as diverse network densities, highly dynamic topology and intermittent connectivity make data dissemination as an essential service and challenging task. Different approaches and protocols are studied to improve information dissemination in vehicular network. Most of these were designed to operate exclusively under sparse or dense networks. In addition the existing solution does not effectively address broadcast storm and network partition problem simultaneously. We propose a multi hop broadcast scheme which employs two mechanisms store-carry-forward and broadcast suppression to distribute the broadcast message to a group of vehicles, within area of interest, over diverse traffic condition with low delay, low overhead and high delivery ratio with the minimum of packet loss.

Fuel tank in an automobile is used as a reservoir for gasoline fuel which is used to propel the vehicle. The design of this fuel tank is of critical importance as it can lead to explosion if not designed properly. Also the capacity of the fuel tank plays an important role in deciding the range of the vehicle between fuel refills. In this project we are undertaking Design analysis and Modification of an existing a commercial passenger car’s fuel tank with consideration to ARAI Fuel tank specifications (AIS-095: 2007 Requirements for Metallic Fuel Tanks of Automotive Vehicles), the model of the car is “Maruti-800”. All the commercial passenger cars available in India have to comply with the design and safety regulations put forth by Government of India to regularize the Automobile market through the Automotive Research Association of India (ARAI). These regulations also include the design requirement for fuel tank. Unless the fuel tank meets these requirements, it cannot be installed in an automobile. Thus the fuel tank we are investigating will be first analyzed for the existing design, once it is analyzed it will be modified either to reduce the weight of the tank or to increase the strength of the fuel tank or both. Once the primary analysis of the current design is completed, the subsequent modifications and changes in the design will be undertaken. Further the new design with modifications will be analyzed in compliance with ARAI regulations and it must comply with the same. Finally the modified design will be published through manufacturing drawing and project thesis.

construction of tall buildings has laid more challenges for engineers to meet the requirements with respect to the demand growth. In the recent trend of tall buildings, lateral loads due to wind or seismic action are resisted by a arrangement of coupled shear walls. But when the structure increases in height, the stiffness of the structure becomes more important and introduction of outrigger beams between the shear walls and exterior columns is more commonly used to give sufficient lateral stiffness to the structure. The outrigger system is one of the most commonly used lateral load resisting structural system as to mitigate the excessive drift due to lateral load in an effective manner. The analysis has been carried out to study the effect and performance of outrigger system in 30 story building. The outrigger system is provided at different levels along the height of the building by varying the relative stiffness. Loads are considered as per Indian Standards IS: 875(Part1)-1987 and IS: 1893(Part-1) - 2002. The analysis is done with Equivalent static method for different seismic zones. The modeling and analysis were performed using finite element software ETABS 9.7.4.It is infer that, with the increase in relative stiffness of the outrigger system, there is a decrease in lateral displacement and inter-story drift. Further there is increase in base shear of the structure with higher relative stiffness in all seismic zones.

Power reduction is nowadays becoming the first consideration in VLSI design. Low power design is one of major concerns in deeply scaled CMOS technologies. Consequently, the need for power efficient design techniques has grown considerably. Several efficient design techniques have been proposed to reduce both dynamic as well as static power in VLSI circuit applications. Clock gating is one of the most elegant and classic techniques for reduction of dynamic power, major contributor in total power consumption of any VLSI circuit. Since clock signal have been a great source of power dissipation in synchronous circuits because of high frequency and load. So , by using clock gating one can save power by reducing unnecessary switching activity inside the gated module. In this paper two most popular techniques of clock gating are compared for their power saving performance, first is AGFF(Auto-gated FF) based and second is DDFF(Data driven flip flop) based. These designs are implemented using Cadence ADE(Analog design tool) and simulation results shows around 40% power saving using AGFFs and around 25-30% power saving using DDFFs.
