Abstract

A control chart is a statistical device used for the study and control of repetitive process. Shewhart (1931) of bell telephone laboratories suggested control charts based on the 3 sigma limits. Now the companies started applying 6 sigma initiatives in their manufacturing process, which results in lesser number of defects, are focused in identifying the causes due to assignable causes of variation. The companies practicing 6 sigma initiatives is expected to produce 3.4 or less number of defects per million opportunities, a concept suggested by Motorola (1980). If the companies practicing 6 sigma initiatives use the control limits suggested by Shewhart, then no point fall outside the control limits because of reduced variation. In this paper an attempt is made to construct a 6 sigma based exponentially weighted moving average control chart specially designed for the companies adopting 6 sigma initiatives in their organization. Suitable table is also constructed and presented for the engineers to take quick decisions.

Abstract

Roads, and means of transport, make a crucial contribution to economic development, growth and bring important social benefits. Poorly maintained roads constrain mobility, significantly raise vehicle operating costs, increase accident rates and their associated human and property costs, and aggravate isolation. The first step for road maintenance is analyzing the present condition of a particular road. The existing method of allowing an engineer to visit the road by himself or by a group headed by him and based on his report further action is initiated by the highway department. But what comes to our mind is that these people are wasting precious fuel for their vehicle just to study the present condition of the particular road also till dawn to dusk, our roads will be very busy due the heavy flow of vehicle,and this will definitely affect clear observation of the condition of the particular road unless, it is not heavily damaged. Also the mood of the person, his condition etc. depend a lot on his observation of that road. To overcome the above difficulties we propose "sculpting video images" for identifying the condition of a particular road. In this approach, we use a web cam or a surveillance camera for recording the entire road. Here the camera will be fixed into a route bus that is plying through that road. By selecting a route bus, we are able to conserve the fuel that was wasted for a separate site inspection. Back ground extraction, Object Segmentation and Stitching are the various steps in shaping the sculpting video from the original.

Abstract

In this paper, we consider the issue of efficient broadcasting in mobile ad hoc networks (MANETs) using network coding and directional antennas. Network coding-based broadcasting focuses on reducing the number of transmissions each forwarding node performs in the multiple source/multiple message broadcast application, where each forwarding node combines some of the received messages for transmission. With the help of network coding, the total number of transmissions can be reduced compared to broadcasting using the same forwarding nodes without coding. We exploit the usage of directional antennas to network coding-based broadcasting to further reduce energy consumption. A node equipped with directional antennas can divide the omni directional transmission range into several sectors and turns some of them on for transmission. In the proposed scheme using a directional antenna, forwarding nodes selected locally only need to transmit broadcast messages, original or coded, to restricted sectors. We also study two extensions. The first extension applies network coding to both dynamic and static forwarding node selection approaches. In the second extension, we design two approaches for the single source/single message issue in the network coding-based broadcast application. Performance analysis via simulations on the proposed algorithms using a custom simulator is presented.

Abstract

The sampling plan CSP - T is a multilevel continuous sampling procedure that reduces the sampling frequency upon demonstration of superior product quality. In this paper a procedure for constructing Continuous Sampling Plan-T (CSP-T) indexed through the Convex Combination of Average Outgoing Quality Limit (AOQL) and Maximum Allowable Average Outgoing Quality (MAAOQ) is presented. This plan may safeguard the interests of both producer as well as consumer by properly choosing a right combination using the gain parameter . A table is also provided for the easy selection of the plan when = 0.3, = 0.6 and MAPD = 0.0025.

Abstract

Video has much higher data rate than speech or audio, and in a great deal of time video requires only one-way streaming and can therefore tolerate long delays in the streaming network. A successful streaming application requires a well –designed system that takes into account each of these elements [3.159].Streaming in data networks is implemented as part of the application-layer protocols of the transmission, such as User Data gram Protocol (UDP) and TCP at the transport layer. As an extensible signaling protocol, Resource Reservation Protocol (RSVP) can be applied in developing video surveillance system. This paper focuses on how to keep surveillance capability when the umber of video surveillance system increases. Based on the study of the RSVP Protocol, we analyze the drawback of the existing video surveillance system model, and propose the scalable service model for video surveillance system. By this model, the extra service requests can be transferred and served in the cooperated video servers. The paper presents the video surveillance control policy of the model in detail. We developed a prototype of video surveillance system based on above model.

Abstract

Objectives: Bluetooth is extending to the blooming Internet of Things (IoT). This article provides an extensive literature survey on the security mechanisms; operational range of Bluetooth. Statistical Analysis: The user can achieve 3 Mbps data rate across an operational range of 100 meters. Bluetooth is a pretty impressive technology that connects and controls all the devices over a distance by using an IoT enabled APP due to which is there is a high possibility of Bluetooth charging for its services like the Internet Service Provider (ISP). Bluetooth 4.0 features reliable pairing and encryption whereas the earlier versions had less importance on security. Findings: In spite of the inherent security in Bluetooth, insidious security issues remain around Bluetooth transfer. Most of the problems were identified and rectified but still as the usage and technology improves, undiscovered problems bloom. There is no software in Bluetooth that has zero security vulnerabilities. Security threats can be overcome by generating a random key. This key is generated in random by combining the significant features of the device along with the customized features of the person. Improvements: Security can be upgraded by improving the strength of Authentication; Encryption algorithm; Augmenting Range of Bluetooth by making it IoT Enabled.

Abstract

Face verification is an important problem. The problem of designing and evaluating discriminative approaches without explicit age modelling is used. To find the gradient orientation discard magnitude information. Using hierarchical information this representation can be further improved which results in the use of gradient orientation pyramid. When combined with a structural risk minimization support vector machine with genetic algorithm, gradient orientation pyramid demonstrate excellent performance. Gradient Orientation of each color channel of human faces is robust under age progression. The feature vector which is computed as the cosines of the difference between gradient orientations at all pixels, is given as the input to the structural risk minimization support vector machine classifier. The classifier is used to divide the feature space into two classes, one for the intrapersonal pairs and the other for extrapersonal pairs. Genetic algorithm plays an important role in improving the performance of the system. The system outperformed other classifiers such as support vector machine and boosting support vector machine.

Abstract

Bisthiourea Potassium nitrate, a new semiorganic nonlinear optical crystal, has been grown by solution growth slow evaporation technique for the first time. The grown crystal were characterised by single XRD to conform lattice parameter. The presence of functional groups was confirmed by using fourier transform infrared (FTIR) analysis. Optical behaviour such as UV – Vis – NIR absorption spectrum was carried and the UV cut-off wavelength for the grown crystal is at 270 nm. Thermal analysis was carried out to determine the thermal stability and the melting point of the grown crystal using TG/DTA. The mechanical properties of the grown crystals have been studied using Vickers micro hardness tester for different loads. Second - Harmonic generation were investigated to explore nonlinear optical characteristics of the materials using Kurtz powder technique.
