Problems are faced while setting up and using a MANET which is both reliable and secure. Transmitting message over multiple paths will increase the security and reliability of transmission in an open collaborative MANET environment where any node can maliciously or selfishly disrupt and deny communication of other nodes. An SMT protocol [1] provides a way to secure message transmission by dispersing the message among several paths with minimal redundancy. The multiple routes selected are known as APS — Active Path Set. An improved way of secured and reliable communication in military using MANETS is presented in this work. This work is towards improving the security of the message transmission among multiple routes by including the most reliable routes in the active path sets through the identification and removal of Byzantine Faults. The route discovery process with binary search probing technique is resilient to Byzantine failures caused by individual or colluding nodes. Malicious links are detected and these links are then avoided by multiplicatively increasing their weights. The fault detection algorithm bounds logarithmically (log n — n the number of nodes in the path), so the delay is reduced drastically. The simulated implementation of the work clearly shows 16 percent increase in average throughput.","PeriodicalId":184011,"journal":{"name":"2011 3rd International Conference on Electronics Computer Technology","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122130279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need of edge detection is to find the discontinuities in depth, discontinuities in surface orientation, changes in material properties and variations in scene illumination. Remote sensing images are generally corrupted from noise. Mathematical morphology is a new technique for edge detection. It is a theory and technique for analysis and processing of geometrical structures, based on set theory. Mathematical morphology was originally developed for binary images, and later extends to grey scale functions and images. Basically the noise can be easily suppressed by mathematical morphology. So by using mathematical morphology the image can be enhanced and the edges can be detected. The result of edge detection using mathematical morphology will be compared with Sobel edge detector, Prewitt edge detector, laplacian of gaussian edge detector and Canny edge detector.","PeriodicalId":184011,"journal":{"name":"2011 3rd International Conference on Electronics Computer Technology","volume":"15 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128957789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arthrodesis is a fusion of the two bones which will restrict the joint range of motion. Arthroplasty involves replacing the diseased joint with a prosthesis which is preferable to arthrodesis due to the restoration of normal joint function. In arthroplasty, a hinged prosthesis is inserted between the metacarpal and the first phalanx. Implants made were introduced to allow maximum joint flexibility and reduce joint pain effectively. Surgical treatment of Metacarpophalangeal joint fracture use prosthesis for the joint replacement. Even though mobility is restored to the joint, there have been reports of complications associated with implant instability and wear. In this study prostheses for metacarpophalangeal joint replacement have to be designed and analyzed the stability of the implant using 3Dimensional Finite Element Analysis. Different load conditions were given to analyze the stress developed, using ANSYS. Computed tomography data of the middle finger was used to construct the joint and a load was applied to the proximal interphalangeal joint to simulate flexion. CT data of the fractured finger is imported into MIMICS software. Using the tools in Mimics software segmentation of the finger can be performed. Design a suitable Swanson implant for the metacarpophalangeal fracture using Autodesk Inventor software. Fixation of the implant to the fracture location was performed using MIMICS so as to reduce the number of triangles and imported to ANSYS software for the analysis and this can be performed by giving different load conditions. Compare the FEA of normal finger with the implant fixed finger.","PeriodicalId":184011,"journal":{"name":"2011 3rd International Conference on Electronics Computer Technology","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129042047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implant success is a function of biomaterials and biomechanical factors, including: materials and material processing; mechanisms of implant/tissue attachment; mechanical properties; implant design; loading type; tissue properties; stress and strain distributions; initial stability and mechanisms of enhancing osseo integration; biocompatibility; and surface chemistry, mechanics, and bone-binding ability of the implant. 3D reconstructions are used to validate procedures numerically preceding experimental analysis. This study outlines the methods used to reconstruct a 3D model of the mandible and evaluating the miniplated mandible for normal functioning. A CT scan from a 22-year-old male patient with a healthy un fractured mandible and also CT scan of 22 year old patient with left symphaseal fracture, and CT scan post surgery ie plated mandible was obtained. A 3D reconstruction was carried out using MIMICS via thresholding and segmentation techniques. Boundary conditions and muscle forces were applied, and simulations were performed using ANSYS 10 workbench. 3D reconstruction allows for precise anatomical dimensions, which can be used for further engineering analysis. Using Finite Element Analysis results showed that the mandible model returned to normal function post-plating. The study shows the clinical relevance of 3D reconstructions to plan surgical procedures. Results illustrate the benefit of carrying out FEA as a prerequisite to experimental modeling and as a method of pre-validating surgical procedures.","PeriodicalId":184011,"journal":{"name":"2011 3rd International Conference on Electronics Computer Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129046652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
