The ABC algorithm is a new meta-heuristic approach, having the advantages of memory, multi-characters, local search, and a solution improvement mechanism. It can be used to identify a high quality optimal solution and offer a balance between complexity and performance, thus optimizing forecasting effectiveness. This paper proposes an efficient prediction model for forecasting of short and long range stock market prices of two well know stock indices, S&P 500 and DJIA using a simple adaptive linear combiner (ALC), whose weights are trained using artificial bee colony (ABC) algorithm. The Model is simulated in terms of mean square error (MSE) and extensive simulation study reveals that the performance of the proposed model with the test input patterns is more efficient, accurate than the PSO and GA based trained models.
ABC算法是一种新的元启发式算法,具有记忆、多字符、局部搜索和求解改进机制等优点。它可以用来识别高质量的最优解决方案,并提供复杂性和性能之间的平衡,从而优化预测的有效性。本文提出了一种简单的自适应线性组合器(ALC)预测标准普尔500指数和道琼斯工业平均指数的短期和长期股票市场价格的有效预测模型,其权重使用人工蜂群(ABC)算法进行训练。采用均方误差(MSE)对该模型进行了仿真,大量的仿真研究表明,与基于粒子群算法和遗传算法的训练模型相比,该模型具有更高的效率和准确性。

The Software Requirements specification (SRS) of an information system contains description of various usecases that can be clustered as real worlds for different actors. Though, usecase diagram depicts the real world for each actor, there may be presence of some secondary actors for each real world. Thus, the real worlds of the actors are not completely isolated real worlds; there exists some sort of overlapping. This overlap indicates some sort of redundancy in the design diagrams of the same type. When this is transformed into code, the redundancy persists in the code also. The redundancy in the code always gives scope for inconsistency and defers integrity. To avoid this, there is a necessity to identify the usecase hierarchies and reflect them in usecase package diagram. This paper attempts to use the usecase diagrams, then develops automated methodology to identify the object classes participating in each usecase. It also proposes an automated methodology for design of usecase hierarchies based on "Extends", "Uses" and Groups". This paper considers the SRS of an information system. Then, using [1], molds it, abstracts its control flow in the form of CFT [1, 2, 3], designs DFT [1, 2, 3], of it & then abstracts the relevant sequence of statements for an each usecase of an actor. This paper presents our proposed methodology that identifies all possible interrelationships between usecases, forms the hierarchies of usecases using de-facto standards of hierarchical levels [4, 5]. This reorganization eliminates the redundancies and packages the usecase incorporating the common reuse and common closure principles. Here, we have also proposed the use of class diagram for the design of usecase hierarchies which may later used for the development of usecase package diagram.
信息系统的软件需求规范(SRS)包含各种用例的描述,这些用例可以作为不同参与者的真实世界聚集在一起。尽管用例图描述了每个参与者的真实世界,但是对于每个真实世界可能存在一些次要参与者。因此,演员的真实世界并不是完全孤立的真实世界;存在某种重叠。这种重叠表明同一类型的设计图中存在某种冗余。当它被转换成代码时,冗余也会在代码中存在。代码中的冗余总是为不一致提供了空间,并延迟了完整性。为了避免这种情况,有必要确定用例层次结构,并在用例包图中反映它们。本文尝试使用用例图,然后开发自动化的方法来识别参与每个用例的对象类。它还提出了一种基于“扩展”、“使用”和“组”的用例层次结构设计的自动化方法。本文研究了信息系统的SRS问题。然后,使用[1]对其进行建模,以CFT[1,2,3]的形式抽象其控制流,设计其DFT[1,2,3],然后为参与者的每个用例抽象出相关的语句序列。本文提出了我们提出的方法,该方法识别用例之间所有可能的相互关系,使用层次层次的实际标准形成用例的层次[4,5]。这种重组消除了冗余,并将用例打包为包含公共重用和公共闭包原则的用例。在这里,我们还建议使用类图来设计用例层次结构,这些层次结构以后可能用于开发用例包图。

Development of adaptive channel equalization using DE 基于DE的自适应信道均衡的开发

The digital channel equalizers are located in the front end of the receivers to avoid the effect of Inter-Symbol-Interference (ISI). In this paper, the equalization problem has been viewed as an optimization problem. In past the Least Mean Square Algorithm (LMS), Recursive least square (RLS), Artificial Neural Network (ANN) and Genetic Algorithm (GA) have been successfully employed for nonlinear channel equalization. The LMS, RLS and ANN techniques are derivative based and hence are chances that the parameters may fall to local minima during training. Though GA is a derivative free technique, it takes more converging time. We propose a novel equalization technique based on Differential Evolution (DE). DE is an efficient and powerful population based stochastic search technique for solving optimization problems over continuous space and hence the channel equalization performance is expected to be superior.
为了避免码间干扰(ISI)的影响,数字信道均衡器位于接收机的前端。本文将均衡问题看作是一个优化问题。在非线性信道均衡中,已有最小均方算法(LMS)、递推最小二乘算法(RLS)、人工神经网络(ANN)和遗传算法(GA)等成功应用。LMS、RLS和ANN技术是基于导数的,因此在训练过程中参数有可能降至局部最小值。虽然遗传算法是一种无导数的技术,但其收敛时间较长。提出了一种基于差分进化(DE)的均衡技术。DE是一种高效且强大的基于种群的随机搜索技术,用于解决连续空间上的优化问题,因此信道均衡性能有望取得优异的成绩。

Human body tracking system based on DWT and Mean-shift algorithm on ARM-Linux platform ARM-Linux平台上基于DWT和Mean-shift算法的人体跟踪系统
Pub Date : 2012-10-01 DOI: 10.1109/WICT.2012.6409168
G. Rakate
A modified human body tracking system based on Discrete Wavelet Transform (DWT) and Mean-shift algorithm is proposed. Most of the traditional object tracking systems have many disadvantages like complexity, high computation power and large size. Here, whole system is implemented on ARM-Linux platform with camera mounted on rotary platform. DWT divides a frame into four different frequency bands without losing spatial information. So it neglects most of the fake motions in background as they are decomposed into high frequency wavelet sub-band. Color and spatial information are used as tracking parameters. Mean-shift algorithm takes less number of calculations while converging to new object search window. Ultimate aim of this project is to implement single human body tracking system on ARM-Linux platform, for which minimum computations should be performed. Combination of DWT and Mean-shift algorithm significantly decreases computation power. As shown in results, human body tracking system is successfully implemented.
提出了一种基于离散小波变换和Mean-shift算法的改进人体跟踪系统。传统的目标跟踪系统大多存在复杂、计算能力大、体积大等缺点。整个系统在ARM-Linux平台上实现,摄像机安装在旋转平台上。DWT在不丢失空间信息的情况下将一帧分成四个不同的频带。该算法将背景中的大部分伪运动分解为高频小波子带,从而忽略了伪运动。使用颜色和空间信息作为跟踪参数。Mean-shift算法在收敛到新对象搜索窗口时,计算次数较少。本项目的最终目标是在ARM-Linux平台上实现单个人体跟踪系统,该系统需要最少的计算量。DWT与Mean-shift算法的结合显著降低了计算量。结果表明,人体跟踪系统成功实现。

Assessment for possible drug application delays in MCT strategy due to pathophysiological constraints of cancer 由于癌症的病理生理限制,MCT策略中可能的药物应用延迟的评估

Different analytical modelling showed that metronomic chemotherapeutic (MCT) strategy is a better option than maximum tolerable dosing (MTD) for the treatment of cancer under the condition of malignancy. In this work, a major physiological constraint, drug clearance rate has been considered. Incorporating it into analytical state-space models, the transformation of the overall system has been examined through computer simulations. Accumulation of drug, dead tumor cells and metabolites produced by living tumor cells in turn affect the subsequent drug application and thereby the therapeutic procedure and its outcome. Simulation results suggest that subsequent drug administration delay increases gradually with time due to this constraint.
不同的分析模型表明,在恶性肿瘤条件下,节律化疗(MCT)策略比最大耐受剂量(MTD)治疗癌症更好。在这项工作中,主要考虑了生理上的制约因素,药物清除率。将其纳入分析状态空间模型,通过计算机模拟检查了整个系统的转换。药物、死亡肿瘤细胞和活肿瘤细胞产生的代谢物的积累反过来影响随后的药物应用,从而影响治疗过程及其结果。模拟结果表明,由于这一约束,后续给药延迟随时间逐渐增加。

As Short Message Service (SMS) is now widely used as business tool, its security has become a major concern for business organizations and customers. However, their security is a critical issue cumbering their application and development. This paper analyses the most popular digital signature algorithms such as DSA, RSA and ECDSA and compared these algorithms. These signature algorithms were implemented in Java with various different key sizes set. Experimental comparison results of the three signature algorithms were presented and analysed. The results show that ECDSA is more suitable to generate the signature and RSA is more suitable to verify the signature on mobile devices. The experimental results are presented to show the effectiveness of each algorithm and to choose the most suitable algorithm for SMS digital signature. Next, we propose a new algorithm for digital signature based on ECDSA. At the end, conclusion and future extension of this work is discussed.

This paper proposes parallel scale space construction of Scale Invariant Feature Transform (SIFT) using SIMD hypercube. The parallel SIFT approach is used for iris feature extraction. The input iris images and Gaussian filters are mapped to each processor in the hypercube and convolution takes place in each processor concurrently. The time complexity of parallel algorithm is O(N2) whereas sequential algorithm performs with complexity of O(lsN2), where l is the number of octaves, s is the number of Gaussian scale levels within an octave for N2 sized iris image.

The time complexity of parallel algorithm is O(N2) whereas sequential algorithm performs with complexity of O(lsN2), where l is the number of octaves, s is the number of Gaussian scale levels within an octave for N2 sized iris image.","PeriodicalId":445333,"journal":{"name":"2012 World Congress on Information and Communication Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133044203","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}

Though the vision of autonomic computing (AC) is highly ambitious, an objective analysis of autonomic computing and its growth in the last decade throw more incisive and decisive insights on its birth deformities and growth pains. Predominantly software-based solutions are being preferred to make IT infrastructures and platforms, adaptive and autonomic in their offerings, outputs, and outlooks. However the autonomic journey has not been as promising as originally envisaged by industry leaders and luminaries, and there are several reasons being quoted by professionals and pundits for that gap. Precisely speaking, there is a kind of slackness in articulating its unique characteristics, and the enormous potentials in business and IT acceleration. There are not many real-world applications to popularize the autonomic concept among the development community. Though, some inroads has been made into infrastructure areas like networking, load balancing etc., very few attempts has been exercised in application areas like ERP, SCM, or CRM. In this paper, we would like to dig and dive deeper to extract and explain where the pioneering and path-breaking autonomic computing stands today, and the varied opportunities and possibilities, which insists hot pursuit of the autonomic idea. A simplistic architecture for deployment of autonomic business applications is introduced and a sample implementation in an existing CRM system is described. This should form the basis of new start and ubiquitous application of AC concepts for business applications.
尽管自主计算(AC)的愿景是雄心勃勃的,但对自主计算及其在过去十年中的发展进行客观分析,可以对其出生畸形和成长痛苦提供更深刻和决定性的见解。主要是基于软件的解决方案被首选为IT基础设施和平台,在其产品、输出和前景中具有适应性和自主性。然而,自动驾驶汽车的发展历程并不像行业领导者和杰出人士最初设想的那样充满希望,专业人士和权威人士援引了几个原因来解释这一差距。准确地说,在阐述其独特的特点方面有一种懈怠,在业务和IT加速方面有巨大的潜力。在开发社区中推广自治概念的实际应用程序并不多。尽管在网络、负载平衡等基础设施领域取得了一些进展,但在ERP、SCM或CRM等应用领域却很少有尝试。在本文中,我们将进一步挖掘和深入,提取和解释开创性和开创性的自主计算今天所处的位置,以及各种机会和可能性,这坚持了对自主思想的热烈追求。介绍了用于部署自主业务应用程序的简单架构,并描述了现有CRM系统中的示例实现。这应该成为业务应用程序中AC概念的新起点和普遍应用的基础。
