Abstract: Noise pollution has become a major concern for communities living in the Chennai city. Noise pollution of urban areas is one of the serious factors that the local agencies and state authorities have to consider in decision making processes. In the reality, noise travels in all direction. Elevated noise levels due to vehicular traffic are cause of great concern in residential areas. Residents living in high rise buildings are also severely affected by traffic noise. It is therefore important to develop noise maps that can show influence of noise in all direction. The spatial analysis and geo statistical methods of GIS can play an important role to control noise pollution. GIS provide framework to integrate noise calculation models with spatial data that can be used for building noise maps. A case study was illustrated using the developed noise maps. This involved building simple, generation of observation point and noise calculation using observed noise data. In this study an attempt is made to monitor the noise pollution due to vehicular traffic at one of the major intersection Porur using digital sound level meter. The variation in the noise levels and traffic volume data in the peak hours are studied and presented as noise map for the selected location and the vulnerable zones are also identified in this study. This study also includes the effects and remedies which can be provided for minimizing the noise pollution.

Abstract: Cyber crimes are becoming increasingly sophisticated and have more severe economic impacts. Each attacker goal can be divided into four main classes: Interruption, interception, modification and fabrication. Based on the attacker goals there are mainly two types of attack, active attack and passive attack. Active attacks are those in which attacker can modify information, interruption services and aim to gain unauthorized access to the network systems. During passive attack, the attacker simply monitors the transmission between the two parties and capture information that is send and receive. For this many traditional network devices such as Intrusion Detection System (IDS), firewalls and security scanners are available. However these techniques will not be able to detect the IP spoofing attacks. And also the spoofing attacks are man-in-the-middle attack. Hence there should be some mechanism by which such attacks can be detected. Through this paper we aim to make a comparative study on various mechanisms by which IP spoofing attack can be detected and specify the different available techniques to prevent the IP spoofing attack. First a penetration test method is presented to detect IP spoofing through the design flaws. Second paper, Defense against Spoofed IP Traffic Using Hop-Count Filtering, says how IP spoofing can be detected using hop count value. The third paper, A protection Method against Unauthorized Access and Address Spoofing for Open Network Access Systems, which proposed a system for IP spoofing detection has been studied. Finally a comparison of these three methods has been made. The forth paper, Enhanced ARP: Preventing ARP Poisoning-Based Man-in-the-Middle Attacks, defines how to enhance the ARP to detect and prevent man-in-the-middle attack. Through our study we concluded that the system proposed in A protection Method against Unauthorized Access and Address Spoofing for Open Network Access Systems is more efficient and less complex that the other two techniques.

Abstract: The development of rock blasting technology is dynamic in nature and concepts of blast theory were customized from time to time based on field results. A number of physical models were tested and verified to comprehend effect of explosive types, blast geometry, rock types etc. Field experiments are time consuming as well as costlier too and many a times it is not possible to conduct field trials with varying parameters due to production pressure. Although, advance field instrumentation technology have been developed to monitor the rock blasting phenomenon but still there are more critical parameters which cannot be measure from field experimentation because of short duration of time. As a results, numerical modeling tool are now considered to be versatile and expedient to simulate the prototype more efficiently. This paper mainly focuses on the results of dynamic numerical modeling using Abaqus/explicit tool to understand rock mass respond and its breakage mechanism, energy utilization history etc. In this paper, a field condition was simulated for single and multiple hole blast to understand the wave propagation mechanism around the blast vis-à-vis effective energy utilization.

Abstract: Past few years an increasing interest in the surface finish produced in turning operation to obtain a product of high quality, the new cutting tool materials like high performance ceramics, coated carbides has been seen which have greatly improved machining of several engineering materials. The productivity during manufacturing can be enhanced by reducing machining cost and selecting appropriate machining parameters. The performance of machining process is depends on various parameters like tool geometry parameters, cutting parameters, tool materials, work piece materials. In this research work the effect of different back rake angle along with cutting parameters and speed has been investigated while machining AISI H11 steel with single coated carbide tools.
