END-TO-END packet delay is one of the canonical metrics in Internet Protocol (IP) networks and is important both from the network operator and application performance points of view. The motivation for the present work is a detailed know-ledge and understanding of such "through-router" delays. A thorough examination of delay leads inevitably to deeper quest-ions about congestion and router queuing dynamics in general. Although there have been many studies examining delay statistics and congestion measured at the edges of the network, very few have been able to report with any degree of authority on what actually occurs at switching elements. In existing system the single-hop packet delay measured and analyzed through operational routers in a backbone IP network. However since the router had only one input and one output link, which were of the same speed, the internal queuing was extremely limited. In this paper work with a data set recording all IP packets traversing a Tier-1 access router. All input and output links were monitored, allowing a complete picture of congestion and in particular router delays to be obtained. This paper provides a comprehensive examination of these issues from the understanding of origins and measurement. © 2011 IEEE. Source

The precise estimation of dielectric constant is very essential requirement in several embedded applications. The cavity resonator and ring oscillator based techniques work well, but require costly setup for dielectric constant measurement. These techniques also become specific to a frequency range for precise estimation. The digital techniques for estimating the dielectric constant are investigated here. The Field Programmable Gate Array (FPGA) based hard wired digital logic with high precision computation is used for estimating the dielectric constant. The simulation and synthesis is carried out in Xilinx ISE environment and results are analyzed by varying the dielectric constant. The realized logic is synthesized to Spartan-6 FPGA and observed that only 10% of logic resources are occupied in Spartan-6 LX16 device, reporting maximum operable frequency of 300 MHz. As a result the proposed scheme can be used for dielectric constant measurement at any frequency up to 25 MHz. © 2013 IEEE. Source

This work incorporates the classification of objects as Manmade or Natural using Kernel functions based Support vector machines (SVM) on SAR Images. Support vector machine uses training images to train a classifier and this classifier is tested on the test images. Training Images are classified into positive for natural images and negative for manmade objects. Test Images are the SAR regions under consideration. The non linear image data is mapped into piecewise linear data using a kernel function. SVM Method with different kernel functions is used to categorize SAR images. The performance of each kernel function is measured by using parameters like False Alarm (FA) and Target miss (TM). They indicate the percentage of incorrectly detected objects. Simulation results based on Matlab proves the efficiency of different kernel functions for different sets of SAR Images. © Research India Publications. Source

Flexural strength of metakaolin ferrocements was evaluated through laboratory investigation. Reference mortar with OPC of 43 grade and metakaolin mortars with 5-25% metakaolin replacement in the increments of 5% with cement were made. Constant water to cementitious ratio of 0.5 was maintained for all the mortars. Galvanized oven mesh (chicken mesh) was incorporated in the tension zone in one, three and five-layers to investigate the influence of reinforcement. The samples were water-cured for 7, 28, 90 and 180 days. The results show that, up to 15% metakaolin replacement, flexural strengths were higher than control ferrocement at all curing ages and for all mesh layers. However, replacements equal and higher than 20% had lower strengths than control ferrocement for all mesh layers. It was further found that 10% metakaolin is the optimum content for maximum flexural strength. The data presented in this paper are a part of study conducted on ferrocement. © 2013 Elsevier Ltd.

In this study, the impact performance of ferrocement with metakaolin was investigated to explore potential uses of both ferrocement and metakaolin in construction industry. A series of ferrocement specimens were cast with varying number of mesh layers and with varying metakaolin percentages. The specimens were normal water-cured for 180 days. The effect of metakaolin percentage (5–25 %); curing period (7, 28, 90 and 180 days); and number of mesh layers (one, three and five) on impact strength was investigated. The results show that, 10 % metakaolin is the optimum content to obtain maximum impact strength. Up to 15 % metakaolin replacement the strengths are higher than control ferrocement at all curing ages and for all the mesh layers. The results further indicated that metakaolin replacements equal and higher than 20 % yields lower strengths than control ferrocement for all the mesh layers. © 2014 RILEM Source
