Roads are one of the most important infrastructures in any country. The major problem on road based transportation networks is accident. The need of the hour is to implement an expert system which helps in preventing the occurrence of Road accidents. The proposed model reduces the percentage of road accidents by implementing the Vigilant Transport System which exploits the use of “Expert Speed Authority System”. The model makes use of the hybrid adaptive approach while controlling the vehicle. This module is connected with GODS (Geo Obstacle Detection System) that detects the nearby obstacles. And also controls the vehicle depending on the geographic location and the surrounding objects like schools, Hospitals. And a novel EVNS (Emergency Vehicle Notification System) is used that gives e-call to the nearby local authorities. Thereby, informing them about the accidents.

Central Manufacturing Technology Institute, Bangalore, India was using Raytheon precision laser driller/welder which was manufactured around twenty years back. The laser system was manufactured using analog controllers. The company is finding difficulty in procuring analog components which was used twenty years back, during maintenance and feature up gradation. Analog controllers are non-expansible and troubleshooting is difficult. Hence the company want to replace the existing analog controller with any digital controllers. The paper deals with simulation of the system working and safety features using PLC software Zeliosoft2 v4.5 in order to validate that the analog controller could be replaced by digital controller.

Cloud Computing has been envisioned as the next-generation architecture of IT Enterprise. Cloud storage moves the user's data to large data centers, which are remotely located, on which user does not have any control. However, this unique paradigm of the cloud poses many new security challenges which need to be clearly understood and resolved. This work studies the problem of ensuring the integrity of data storage in Cloud Computing. The Cloud Server provides a platform for the Cloud Client to manage their documents. In particular, we consider the task of allowing a third party auditor (TPA), on behalf of the cloud client, to verify the integrity of the dynamic data stored in the cloud. The introduction of TPA eliminates the involvement of the client through the auditing of whether his data stored in the cloud are indeed intact, which can be important in achieving economies of scale for Cloud Computing.

Aircraft applications demand high reliability and high power density while aiming to achieve simplicity in operation, increased fuel efficiency and reduced costs of operation and environmental impact. Fighter aircraft especially, must have high manoeuvrability and must be able to handle huge thrust as compared to passenger aircrafts. This paper deals with the development of an all electric actuator with the view of replacing the existing electro hydraulic actuator which powers the control surface that controls pitching of the fighter aircraft and provides the same torque and displacement with better manoeuvrability. The rotary motion of electric actuator is translated to linear movement of ball screw which controls the angular motion of control surface. Development of electric actuator involves selection of a motor with high torque to provide electric actuation, and simulating it in Matlab with closed loop feedback control. Switched reluctance motor is considered for the application and it is simulated in closed loop with one common switch converter and C-dump converter so as to the best results. A comparative study of the output of the motor is carried out in using the two different converters.

This work holds the objective of investigating the performance of conventional Full Adders (FA) at 28nm regime and then proposes a Transmission Gate (TG) based improved FA circuit of reduced Power Delay Product (PDP). In this design the XOR/XNOR nodes have been optimized to operate at submicron level with lower delay. The work provides full voltage swing even at lower operating voltage by avoiding the threshold loss problem. The low leakage feature of TG technology allows it to deliver high energy efficiency. The modified circuit achieves up to 59.14% and 59.36% improvements in worst case delay and PDP respectively as compared to the conventional TG based FA cells for low power mode of operation. Particularly at lower voltage range and higher speed, the performance is considerably fair. Simulations show that the modified FA circuit is efficient in terms of delay as well as extended region of operation. All simulations are performed with Cadence Virtuoso tool and Eldo simulator for 28nm FDSOI technology.

The most important source of motivation for continuity of technological developments is the constant demand to improve living standards. Today, in this post-PC era, mobile devices and smart devices are handling daily tasks that traditional desktop and laptop computers once handled. In this study, a smart home automation system design is carried out using a blink sensor. The purpose of this blink sensor is to sense an eye blink in real time. The system analyses the eye blink and differentiates between an intentional blink and a normal eye blink. Here multiple eye blinks are required to control more than one appliance. Software is used to check the correctness of the blink sequence and monitor the instantaneous states of the smart home system. This system can not only be used to save electricity, but also to help tetraplegic patients to lead their own life without anyone else's assistance. Tetraplegia is a condition where people are paralysed below their neck. The proposed system can be easily programmed to add new devices for home automation.

When the communication is performed publicly one of the major challenges is the reliability of the communication. When this communication is performed on a cloud like distributed system where all services, products and infrastructure is available publicly with personal access capabilities, the reliability factor becomes more critical. The reliability itself is a complex form of measurement that includes the security, efficiency and the satisfaction level for the customer. In this presented work, a secure and reliable access over the cloud is being presented where different degree of reliability can be achieved by the customer. The presented work is a middle layer architecture where multiple clients are connected with reliability layer as the middle layer to access the multiple clouds. At the time of registration, users can opt the degree of reliability required by selecting the access degree. Based on this requirement, the security level and the cost of the cloud access will be decided. The presented work is the dynamic security structure specification in which all the reliability vectors are divided under 10 reliability features. These features include three main aspects called authenticity, control and availability. The authenticity is here being opted in form of single password authentication, generic authentication, code based authentication. The control is here defined in terms of public key secure data communication, private key secured communication, and tunnel based communication. The availability vector basically defines the authentication required for restricted area access, session based access or all page access. Each vector will be assigned by different cost and weightage vectors. Once the weightage and the cost will be assigned to the system, the fuzzy based analysis will be performed to identify the cost and risk vector over the system in a nominal form. Once a user is registered to the system, he has to select the degree of reliability based on which the security level and the cost of security will be decided for the users. The presented work is implemented in Java environment. The obtained results show the effective cloud security assessment and user security role assignment.

In this paper, a technique to design the 8 bit continuous-time band-pass Sigma-Delta converters for 70 MHz is presented. The conversion from discrete-time (z-domain) loop-filter transfer function into continuous-time (s-domain) is done by using Impulse-invariant-transformation. The transconductor-capacitor filter is used to implement continuous-time loop-filter. A latched-type comparator and a TSPC D Flip-flop are being used as the quantizer of the Sigma-Delta converter. The decimation filter is designed by a CIC Filter and an FIR filter for high-speed. A full adder cell and a TSPC D Flip-flop are used as basic building blocks of CIC Filter and FIR Filter. The 8 bit second-order continuous Sigma-Delta converter circuit has been implemented in Cadence using 180nm CMOS technology and the total power consumption is 34.48 mW. At a supply voltage of 3 V, the maximum SNR is measured to be 49.92 dB, ENOB is measured to be 8.29 bites, propagation delay is measured to be 2.56ns which corresponds to a resolution of 8 bits.

This paper presents the redesigning the distributed analog controller used in Raytheon Laser Precision welder/driller system which is around thirty years old. Main difficulty faced is that, the components associated with distributed analog controller of laser system are now obsolete. Some of the disadvantages of analog controllers are that they are bulky, expensive and complex design making troubleshooting difficult. Taking these disadvantages of analog controller into consideration, digitalizing the controller is important. Digital controller used is dsPIC30F4011, which will take care of the working of three phase rectifier, generating pulses for charging and discharging SCR, looks after system safety features and interlocks.
