Unfortunately, IPv6 is not backward-compatible with the IPv4. It is necessary to consider IPv4-IPv6 protocol conversion. To resolve this problem, in the paper, we use Petri nets to simulate and model the IPv4-Pv6 protocol conversion process. By analyzing the bounded ness, activity and reversibility of the model, we prove that the process can both achieve IPv4-IPv6 conversion and satisfy system security requirements.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133505672","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}

However, most television programs don't offer Chinese subtitles or the sign language, leaving the hearing disabled people unable to obtain the information and enjoy recreational activities as ordinary people do. Therefore, the sign language on television is very important. Comparing to the ordinary computer, the calculation and processing power of the digital TV terminals is nowhere near a computer. Small storage space and low performance restrict the ability of displaying 3D graphics on the television. Therefore, this article uses a 3D graphics mesh simplification method which based on edge collapse, to simplified 3D graphics, and apply it to the sign language on the digital television, to achieve the goal of displaying the 3D sign language graphics smoothly and intuitively on the digital TV terminals.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131338522","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}

Our technical foci are to reduce numerical dissipation by using the MacComark method to solve advection, and respect small scale detail by taking the vorticity confinement force into account. In sharp contrast to other models, we rigorously simplify the physical models of explosions by optimizing some computational steps and adding double density sources, which makes our method to afford lager grid size with high visual quality while achieving real time efficiency. Besides, our method is also flexible enough and we can control the behavior of an explosion by setting different parameter values.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129695291","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}

It occurs when there is a problem with the passage of messages between the muscles and the brain. Some paralyzed people cannot move even a single part of the body other than their eyes. Hence, the main aim of this paper is to design a real time interactive system that can assist the paralyzed to control appliances such as lights, fans etc. or by playing pre-recorded audio messages, through a predefined number of eye blinks. Image processing techniques have been implemented in order to detect the eye blinks. In our system, the face tracking is accomplished by using a set of trained Haar cascade classifier, and a template matching technique is employed to track the eye. Initially, the involuntary blinks of the paralyzed person are used to locate the patient's eyes by finding the number of connected components in a frame. Once the eyes are detected, an online template is created which is then used to track the patient's eye.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121270433","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}

In this paper, we propose holomorphic coordinates that directly take user-specified shape points as handles to produce visually promising conformal deformations for 2D shapes. Based on the theory of holomorphic functions, holomorphic coordinates promise the interpolation and smoothness properties on the shape. Namely, handle points can be moved to the exact locations that the user specifies, and the deformations are smooth all over the shape. We also suggest an algorithm to solve holomorphic coordinates on a grid in a least-squares sense by constructing harmonic and conjugate constraints. Experiments have shown that the numerical errors are close to zero, and deformed shapes can be obtained at an interactive rate.","PeriodicalId":308799,"journal":{"name":"2012 Fourth International Conference on Digital Home","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130861974","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}
