In the current scenario there has been a significant increase in the accidents rate pertaining to reasons like blind spots and confusing lanes. This paper presents a novel idea with use of augmented reality to overcome such issues. In this idea we obtain the 3-D view of the surroundings, including blind spot's view using stereo vision. The results were tested on a miniature scale, were examined under...
A single layer printed compact antenna for X band application is proposed. The proposed antenna, having a total size of 30 × 22 mm, consists of a patch fed by a Microstrip line and a partial ground plane. The slot on patch and the modified ground plane with semielliptical shaped slots on its top edge helps to increase the bandwidth of the proposed antenna. The double-sided printed antenna has a bandwidth...
Taking into account the recent growth in research and development in wireless sensor networks it has been shown that they have a lot of scope in future. It is more important to pay attention to the security of wireless sensor networks as they are highly prone to threats. In this paper we propose a protocol for establishing the security mechanism of wireless sensor networks and devising a scheme for...
Mobile Ad Hoc Network (MANET) consists of dynamic topology as nodes in the network are mobile, and connected via wireless links. Nodes within the cluster communicate directly. However, nodes communicate outside the cluster through a centralized node that is called a Cluster Head Gateway (CHG) [1]. As the number of nodes increases complexity of MANET increases in various issues. Ad hoc wireless network...
The availability of potentially high operation concurrency in various applications has led to the development of VLIW Processors. To reduce the complexity at hardware and power consumption, the instruction scheduling is done statically. The disadvantage of long wires in the VLIW architecture was overcome by clustering of the processors (Eg. TMS320c6000 series). In clustered VLIW processors, the execution...
A fully functional wall painting robot prototype for indoor and outdoor environments has been developed. The prototype development includes building the hardware and software subsystems for the robot. The robot controller has developed using the Altera DE2 Development Board with the software implementation done in Quartus II 8.1 and NIOS II IDE using C language programming. Hardware development of...
The current internet is suffering from its own success. As the number of users on the internet and the variety of application transported are growing steadily at high rate. The available bandwidth as well as the best effort paradigm is facing limits. Ubiquitous and frequent congestion situation restrict the use of new time interval application like IP telephony, Video conferencing or online games...
Asynchronous design offers an attractive solution to overcome the problems faced by Networks-on-Chip (NoC) designers such as timing constraints. GALS Asynchronous NoCs requires efficient calibrated clocking scheme which has minimum drift, independent of Process Voltage Temperature(PVT), use minimum static and dynamic power. Clocking scheme should enable smooth synchronization among different clock...
This paper presents an improved version of a simple rule induction algorithm known as ELEM. Compared to LEM1[5], LEM2[5], the new algorithm, ELEM, is faster as it requires fewer operations in its rule generation process. The results obtained have demonstrated the strong performance of the algorithm. The numerical experimental results demonstrate that the method of rule induction proposed in this paper...
This paper discusses the design of micro power Sigma-delta modulator with GA based oversampling technology. This Sigma-delta modulator design is paid special attention to its low power application of portable electronic system in digitizing biomedical signals such as Electro-cardiogram (ECG), Electroencephalogram (EEG) etc. [1]. A high performance, low power second order Sigma-delta modulator is more...
The advent of Multi Protocol Label Switching (MPLS) has reach beyond the original idea behind the development of MPLS. The original idea behind MPLS was to facilitate fast packet switching using 20 bit MPLS Label header. Presently Traffic Engineering has drawn considerable major interest of the researcher. In this paper we describe an algorithm to use multiple Link Switching Path (LSP) for MPLS which...
This paper reveals mathematical models of the simplest Mamdani PI/PD controllers which employ two fuzzy sets (N-negative and P-positive) on the universe of discourse (UoD) of each of two input variables (displacement and velocity) and three fuzzy sets (N-negative, Z-zero, P-positive) on the UoD of output variable (control output in the case of PD, incremental control output in the case of PI). The...
Service Robotic application deployments have taken a giant leap in complexity. They have been successfully deployed in wide range of applications from NASA Mars Rovers to domestic lawn mowers. Waypoint Navigation Systems (WNS) can now be used as an alternate Mobile Robot Navigation (MRN) technique with advances in Global Positioning Systems (GPS) and Global Information systems (GIS).Regardless of...
The identification of nonlinear systems with chaotic behavior using a neural network based computational algorithm is presented.. A neural network is trained on the measured output data of the actual system. The network parameters viz. the neural network weights are estimated using the Elman back propagation algorithm .Further, The Rossler and the Chen chaotic systems are used for simulation. The...
The memory of modern computer is layered in a hierarchy, top to bottom primary cache, secondary cache, main memory, virtual memory and distributed memory with more levels to come in the future. Our goal is to automatically achieve that of fine-tuned algorithms on a multi-level memory hierarchy. This automatically is because cache oblivious algorithms no knowledge about any capacity and block size...
Multimedia datas are growing at a fast rate. Music, which is one of the most popular types of online information, is a part of multimedia data and there are now hundreds of music streaming and downloading services operating on the World-Wide Web. Some of the music collections available are approaching the scale of ten million tracks and this has posed a major challenge for searching, retrieving, and...
Researchers in the field of image and video processing use MSE (Mean Square Error) based fidelity metrics to validate their research results. The most popular MSE-based metrics are PSNR (Peak Signal to Noise Ratio) and WPSNR (Weighted Peak Signal to Noise Ratio). When large quantities of data are to be assessed, subjective metric such as MOS (Mean Opinion Score) is not pragmatic since it needs experts...
A Wireless Sensor Network is a network of sensors that senses specified parameter(s) related to environment; processes data locally or in a distributed manner and wirelessly communicates information to central Base Station. The Base Station analyzes information and initiates suitable response if required. The complexities introduced by severely limited processing capabilities, memory and power supply...
The Permanent Magnet Synchronous Motor (PMSM) has been widely used in the low to medium power system due to its characteristics of high efficiency, high torque to inertia ratio, high reliability and fast dynamic performance.

Time synchronization has a paramount role in designing efficient Medium Access Control (MAC) in multi-channel wireless access in vehicular environment (WAVE). In short range communication in WAVE, every On-board unit (OBU) and every roadside unit (RSU) have to concord with message exchanges within control channel (CCH) intervals and service channel (SCH) intervals. Timestamp synchronization has to...
