Pseudo Random Network Coding in Infrastructure to Vehicle Environment for Data Download 基于车辆环境的基础设施伪随机网络编码数据下载
Pub Date : 2015-07-14 DOI: 10.1109/APCASE.2015.65
D. Astudillo, E. Chaput, A. Beylot
This paper introduces a new approach for infrastructure based content distribution in a vehicular network. It is built on broadcasting and pseudo random network coding. Its main strength is that, being broadcast based, it does not need any feedback channel and thus uses less data rate. Data is transmitted exploiting network coding, multiple linear combinations of data are sent. A vehicle needs to receive a defined number of independent linear combinations to decode the data. The server will send a larger number of different linear combinations. The unreliability of broadcast is thus neutralized through a useful redundancy rather than through re-transmission. Finally, computation of the linear combination coefficients is done so that the overhead is the same as it would be without network coding. Depending on the infrastructure deployed, this technique can be a content distribution solution per se or the first step in a more general solution, the second step being based on collaborative download. The high diversity in transmissions will then be a key feature for the performance of such an application.
介绍了一种基于基础设施的车载网络内容分发新方法。它建立在广播和伪随机网络编码的基础上。它的主要优点是,它是基于广播的,不需要任何反馈通道,因此使用较少的数据速率。利用网络编码传输数据,发送数据的多个线性组合。车辆需要接收一定数量的独立线性组合来解码数据。服务器将发送大量不同的线性组合。因此,广播的不可靠性可以通过有用的冗余而不是通过重传来消除。最后,进行线性组合系数的计算,使开销与没有网络编码时的开销相同。根据所部署的基础设施,该技术可以是内容分发解决方案本身,也可以是更通用解决方案中的第一步,第二步是基于协作下载的。传输中的高分集将成为这种应用性能的一个关键特征。

The Weather Research and Forecasting (WRF) is a next-generation mesoscale numerical weather prediction system. It is designed with a dual purpose, forecasting and research. The WRF software infrastructure consists of a number of components such as dynamic solvers and physical simulation modules. Dynamic solvers are intensive computational components of the WRF model. In this paper, the Horizontal Diffusion method, which is part of the ARW (Advanced Research WRF) dynamic solver, is accelerated using GPUs. The performance of the GPU-based method was compared to that one of a CPU-based single-threaded counterpart on a computational domain of 433x308 horizontal grid points with 35 vertical levels. Thus, the achieved speedup is 19x on a NVIDIA Tesla M2090, without considering data I/O.

Future Grid Business Model Innovation: Distributed Energy Resources Services Platform for Renewable Energy Integration 未来电网商业模式创新:面向可再生能源一体化的分布式能源服务平台
Pub Date : 2015-07-14 DOI: 10.1109/APCASE.2015.20

This paper proposes a Distributed Energy Resources Services Platform as an electric grid Business Model Innovation Framework (BMIF) for coordination of distributed energy resources and renewable energy integration. The platform is based on a decentralized and layered architecture and is centered on the concept of electricity prosumers -economically motivated agents (residential, commercial, industrial) - that can produce, store or consume energy. The platform consists of six layers, including: the physical layer, local control layer, cyber layer, system control layer (economic dispatch and real-time control), market transactive layer and business layer. The main objective of the platform is to provide a framework for the coordination of several spatially distributed and heterogeneous subsystems containing energy resources at different time scales and horizons in order to conduct economic emissions dispatch and reserve scheduling to integrate higher amounts of renewable energy, while dynamically maintaining and adapting to user level of service requirements and system level constraints. Using the structure provided by the platform, the benefits of flexible distributed energy resources for different scenarios of renewable energy integration are quantified. The results show that using the platform for coordination of flexible energy, offers the opportunity to integrate higher amounts of renewable energy, reduce carbon emissions and operational costs.
本文提出了分布式能源服务平台作为电网商业模式创新框架,以协调分布式能源与可再生能源的整合。该平台基于分散和分层的架构,并以电力产消者的概念为中心-经济动机的代理人(住宅,商业,工业)-可以生产,存储或消耗能源。该平台由物理层、本地控制层、网络层、系统控制层(经济调度和实时控制)、市场交易层和业务层组成。该平台的主要目标是为多个空间分布的异构子系统提供一个协调框架,以协调不同时间尺度和水平的能源资源,进行经济的排放调度和储备调度,以整合更多的可再生能源,同时动态保持和适应用户层面的服务需求和系统层面的约束。利用平台提供的结构,量化可再生能源集成不同场景下柔性分布式能源的效益。结果表明,使用灵活能源协调平台,提供了整合更多可再生能源的机会,减少了碳排放和运营成本。

Nowadays the plagiarism constitutes a complex problem, due several factors as the incorrect use of new technologies to access and share the information, the different forms and areas where can be present plagiarism (texts, code, images, self-plagiarism, etc.) or the lack of respect to ideas and contributions of other persons. On those grounds, in this paper we present a novel ecosystem to provide support during the development process of new algorithms to detect plagiarism, test the existing algorithms or perform benchmarking analysis. This platform named "NeoPlag" provides a complete set of services that allow developers focusing in design of detection technique, without worrying by deployment issues as development of search services in internet, text extraction, semantic analysis of texts, configuration the citation styles, among several others. In order to analyze the usefulness of the proposed ecosystem, we have developed and uploaded into system a basic detection algorithm based on vector space model. With the developed algorithm we have carried out a benchmarking between our ecosystem and commercial tool (Viper). The achieved results by our proposal are encouraging and shown highest rates of plagiarism detection.
如今,抄袭构成了一个复杂的问题,由于以下几个因素,如不正确地使用新技术来访问和共享信息,不同的形式和领域可能存在抄袭(文本,代码,图像,自我抄袭等)或缺乏尊重他人的想法和贡献。基于这些理由,在本文中,我们提出了一个新的生态系统,在新算法的开发过程中提供支持,以检测剽窃,测试现有算法或执行基准分析。这个名为“NeoPlag”的平台提供了一套完整的服务,使开发人员可以专注于检测技术的设计,而不必担心互联网搜索服务的开发、文本提取、文本语义分析、配置引用样式等部署问题。为了分析所提出的生态系统的有用性,我们开发并上传了一个基于向量空间模型的基本检测算法。通过开发的算法,我们在我们的生态系统和商业工具(Viper)之间进行了基准测试。我们的提案取得了令人鼓舞的结果,并显示出最高的剽窃检出率。

Automatic Segmentation and Analysis of Thermograms Using Texture Descriptors for Breast Cancer Detection 基于纹理描述符的热图自动分割与分析用于乳腺癌检测

Breast cancer is one of the leading causes for high mortality rates among young women, in the developing countries. In Latin American this is an important health problem, for instance in Brazil and Ecuador this is the leading cause of cancer among women around 35 years old. Currently mammography is used as the gold standard for screening breast cancer. However, for young women mammograms are not recommended due the low contrast it presents on dense breasts and alternative techniques must be considered for this purpose. The World Health Organization states that screening programs are the more efficient way to combat this disease. Therefore it is fundamental to address new researches on early detection that are cost-effective and present advantages over the current method (based on the self-examination and mammography). The identification of such disease in early stage increases the prognosis and the survival rate. This article proposes to incorporate a low-cost and non-invasive diagnostic technique based on the use of thermal imaging. A textural analysis (by using statistical descriptors for automatic detection of abnormality in breast thermo grams) is considered for features as well as statistics measures computed from thermo grams' ROI (region of interest). Theses features feed a Nearest Neighbors classifier, where abnormal breasts are was identified with an accuracy of 94.44 %. The results of the study show that using simple textures descriptors, appropriate filtering and enhancement techniques it is possible to detected early onset of breast tumor in women of any age, with breasts of any density or size and even in pregnant women.
在发展中国家,乳腺癌是造成年轻妇女高死亡率的主要原因之一。在拉丁美洲,这是一个重要的健康问题,例如在巴西和厄瓜多尔,这是35岁左右妇女患癌症的主要原因。目前,乳房x光检查被用作筛查乳腺癌的金标准。然而,对于年轻女性,不建议进行乳房x光检查,因为它在致密乳房上显示的对比度较低,因此必须考虑其他替代技术。世界卫生组织表示,筛查项目是对抗这种疾病更有效的方法。因此,解决早期检测的新研究是至关重要的,这些研究既具有成本效益,又比目前的方法(基于自我检查和乳房x光检查)有优势。早期发现可提高预后和生存率。本文建议采用一种基于热成像的低成本、无创诊断技术。纹理分析(通过使用统计描述符自动检测乳房热图中的异常)被考虑用于特征以及从热图的ROI(感兴趣区域)计算的统计度量。这些特征提供给最近邻分类器,其中异常乳房被识别的准确率为94.44%。研究结果表明,使用简单的纹理描述符,适当的过滤和增强技术,可以在任何年龄,任何密度或大小的乳房,甚至孕妇中检测到早期发生的乳房肿瘤。

Solid free form fabrication are now being developed to fabricate scaffolds with controlled architecture for bone tissue engineering. These techniques use computer-aided design (CAD) to aid the design of optimized three-dimensional structures in a large number of materials. The development of mechanical models to simulate the scaffolds behavior for bone tissue engineering represents a relevant area in regenerative medicine. This paper presents a computer tool to design tailored scaffolds as a function of mechanical properties considering a specific kind of bone tissue. The kernel of this tool is formed from a fuzzy inference system (FIS) and a parametric design algorithm. The models obtained from this methodology were evaluated using finite element analysis (FEA) and they exhibit suitable features and characteristics to be used in experimental case studies.

The models obtained from this methodology were evaluated using finite element analysis (FEA) and they exhibit suitable features and characteristics to be used in experimental case studies.","PeriodicalId":235698,"journal":{"name":"2015 Asia-Pacific Conference on Computer Aided System Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130082626","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}

Often, the performance of genetic programming (GP) is explained in terms of building blocks -- high-quality solution elements that get gradually assembled into larger and more complex patterns by the evolutionary process. However, the weak theoretical foundations of GP building blocks causes their role in GP evolutionary dynamics to remain still somewhat of a mystery. This paper presents a methodology for identifying GP building blocks based on their respective sample counts in the population (defined as the number of times they were sampled by the recombination operators and included in surviving offspring). Our approach represents a problem-independent way to identify important solution elements based on their influence on the evolutionary process.
通常,遗传编程(GP)的性能被解释为构建块——通过进化过程逐渐组装成更大、更复杂模式的高质量解决方案元素。然而,GP构建模块的薄弱理论基础导致它们在GP进化动力学中的作用仍然是一个谜。本文提出了一种基于种群中各自的样本计数(定义为重组算子对它们进行采样的次数,并包括在存活的后代中)来识别GP构建块的方法。我们的方法代表了一种独立于问题的方法,根据它们对进化过程的影响来识别重要的解决方案元素。
