Over the last few years, deep artificial neural networks have gotten the most attention in computer science, especially in pattern recognition, machine vision and machine learning. One of its excellent applications is in the emotion recognition via facial expression area. Facial expression analysis is useful for many tasks and the application of deep learning in this area is also developing very fast. We review some recent research works in this domain, introduce some new applications and show the general steps to implementing each of them.

The paper considers the problems related to short-channel effects in a current amplifier, when realized in ultra-deep sub-micron technology. A short description of the circuit and a limitation concerning its basic parameters is given at the beginning. Several steps, allowing an approximate design of the circuit, are outlined. They are applied for design of three versions of the amplifier, each of them is realized with FETs having different channel length: 90 nm, 45 nm and 30 nm. Their basic properties are simulated and discussed, demonstrating the major benefit of the shortening of the channel length—extension of the frequency bandwidth. The problems arising with the shorter channels length are also considered briefly.
本文考虑了在超深亚微米技术中实现电流放大器时与短沟道效应有关的问题。文中首先简要介绍了该电路,并对其基本参数进行了限制。概述了允许对电路进行近似设计的几个步骤。它们被应用于三种版本的放大器的设计,每种都是用具有不同沟道长度的FET实现的:90nm、45nm和30nm。对它们的基本特性进行了模拟和讨论,证明了缩短信道长度的主要好处——扩展了频带宽度。文中还简要考虑了通道长度较短的问题。

Information systems in the health field should be communicating to foster cooperation of professionals in the health process centered on the patient, and to assist in medical decision. Therefore, communication through computer tools and the creation of computerized patient records require the use of semantic repositories whose control is required. Indeed, the sharing of patient data principle is needed particularly because of the development of medical knowledge, which helps to segment the expertise, skills and roles of players. The application of this principle allows greater coordination between professionals and requires appropriate and scalable information systems. The necessary data sharing and the development of information systems strongly emphasizes the issue of semantic interoperability of health systems and management repositories. However, if, in the context of the interoperability of information systems, choice, maintenance and the use of semantic standards are necessary conditions, the behavior of players and practices of evaluation procedures are nevertheless essential component for proper functioning.
在卫生领域的信息系统应沟通,以促进合作的专业人员在卫生过程中以病人为中心,并协助医疗决策。因此,通过计算机工具进行通信和创建计算机化的患者记录需要使用语义存储库,这些存储库的控制是必需的。实际上,由于医学知识的发展,特别需要分享病人数据的原则,这有助于对参与者的专业知识、技能和作用进行细分。这一原则的应用允许专业人员之间进行更大的协调,并需要适当和可扩展的信息系统。必要的数据共享和信息系统的开发强烈强调了卫生系统和管理存储库的语义互操作性问题。然而,如果在信息系统互操作性的背景下,选择、维护和使用语义标准是必要条件,那么参与者的行为和评估程序的实践仍然是正常运作的必要组成部分。

A series of seven computing and online games was reviewed following a criterion based selection process. The games were reviewed relative to their capacity to incorporate elements of gaming comparable to content or themes evident in children’s literature including, type of game, genre, elements of violence, disturbing scenes, gender of key protagonists or heroes, location and relative time frame, as well as major themes, evidence of trauma or PTSD components and elements of grief or loss. Selected games demonstrate some capacity for use in virtual narrative therapy and as virtual methods for facilitating maturing processes, and to some extent may interface with moral development as appropriate for age and level of development. Games also show capacity for modifying affect positively based on themes, but will need additional evaluation or research.
一系列的七款电脑和网络游戏是根据一个基于标准的选择过程进行审查的。对这些游戏进行审查的标准是,它们是否具备与儿童文学中明显的内容或主题相媲美的游戏元素,包括游戏类型、类型、暴力元素、令人不安的场景、主要主角或英雄的性别、地点和相对时间框架,以及主要主题、创伤或创伤后应激障碍成分的证据以及悲伤或失去的元素。选定的游戏展示了在虚拟叙事治疗和促进成熟过程的虚拟方法中使用的一些能力,并且在某种程度上可能与适合年龄和发展水平的道德发展相结合。游戏也显示出基于主题而积极改变影响的能力,但这需要额外的评估或研究。

The United States electric power infrastructure is in an urgent need of renovation. The recent incidents of major power outages in the city of Long Beach, Los Angeles, Simi Valley, San Diego, and San Francisco have drawn attention to the unreliability of California’s electric power system. President Obama discusses America’s aging power infrastructure and California Public Utilities Commission calls for a comprehensive review of the causes of the recent power outages. This report explores GIS (geographic information systems) and their aim to identify a correlation between the power plants age and the power outages in the state of California. Utilizing ArcMap OLS (ordinary least squares) modeling tool, data analysis shows no correlation between the power outages and the infrastructure age.

This paper presents a practical usage of several business process management concepts, technologies and tools in the example of the business process for banking payments system. Seen from one perspective, the actual trend in business management is the transfer from functional to process approach. Process approach is considered as a key tool for improvement of business processes. Implementation of process principles into management brings a lot of changes with positive effects as higher competitiveness, productivity and performance of enterprise are. Seen from another perspective many organizations are taking steps to reduce the amount of paper in their business processes. The trend is particularly strong in the financial services industry, where paper-intensive processes present stringent regulatory requirements for timely processing and for controlling the flow of the documents associated with these processes. In this paper is shown how can the process in financial service industry be improved using these two concepts. First step is to integrate BPM (business process management) and DMS (document management system) and results are monitored using BI (business intelligence) and BAM (business activity monitoring). Time, cost and human resources results before and after the usage of this complex system will be also presented.
本文以银行支付系统的业务流程为例,介绍了几种业务流程管理的概念、技术和工具的实际应用。从一个角度来看,企业管理的实际趋势是从功能方法向过程方法的转变。过程方法被认为是改进业务过程的关键工具。过程原则在管理中的应用带来了许多积极的变化,提高了企业的竞争力、生产力和绩效。从另一个角度来看,许多组织正在采取措施减少其业务流程中的纸张数量。这一趋势在金融服务行业尤为明显,在该行业,纸张密集型流程对及时处理和控制与这些流程相关的文件流提出了严格的监管要求。本文展示了如何利用这两个概念来改进金融服务行业的流程。第一步是集成BPM(业务流程管理)和DMS(文档管理系统),并使用BI(业务智能)和BAM(业务活动监控)监控结果。还将介绍使用该复杂系统前后的时间、成本和人力资源结果。

In this article, we describe Kinoshita’s macroeconomic scheme that is Thetical economics and Antithetical economics on four economic phases. Especially, we focus on transitions among the phases. Four economic phases are Thetical economy, Bubble economy, Bubble collapse economy, and Antithetical economy. We give important roles in the description to bubbles. Occurrence and collapse of bubble cause the transitions of economic phases. So explanations of detailed mechanisms of the bubbles are in the article. We try to show them by varying of the consumption propensity.

Classical Business Intelligence systems are based on common database management systems. The use of such classical, nonpolitical BI systems is not always the best solution. The incorporation of cloud computing technology offers great potential. Therefore, the combination of business intelligence and cloud computing is discussed more and more in science and industry with first products being already available on the market but so far no widespread use has been established. On the one hand, there are less scientifically based progress reports; on the other hand, there is an uncertainty and skepticism. Basic questions regarding the enterprise and software architecture are not yet clear. The absence of standards and transparency promotes skepticism and incomprehension. A lack of comparison and assessment models for BI cloud services and BI cloud systems fueled uncertainty. RABIC, the integrated reference architecture for business intelligence in the cloud, improves this situation by supporting the standardization, increase the transparency and abolish the skepticism. The measures to receive these objectives are to make BI cloud services in a uniform way describable and comparable and to make BI cloud systems assessable, comparable, describable and easier implementable. The vehicles as the integral constituents of the reference architecture are a taxonomy for BI cloud services and an architectural framework for BI cloud systems. This article presents an overview of the reference architecture.
经典的商业智能系统是基于通用的数据库管理系统。使用这种经典的、非政治性的BI系统并不总是最好的解决方案。云计算技术的结合提供了巨大的潜力。因此,商业智能和云计算的结合越来越多地在科学和工业中被讨论,市场上已经有了第一批产品,但到目前为止还没有建立广泛的应用。一方面,缺乏科学依据的进展报告;另一方面,也存在着不确定性和怀疑。关于企业和软件架构的基本问题还不清楚。缺乏标准和透明度会助长怀疑和不理解。缺乏BI云服务和BI云系统的比较和评估模型加剧了不确定性。RABIC是云计算中商业智能的集成参考架构,它通过支持标准化、增加透明度和消除怀疑来改善这种情况。实现这些目标的措施是使BI云服务以统一的方式可描述和可比较,并使BI云系统可评估、可比较、可描述和更容易实现。作为参考体系结构的组成部分的工具是BI云服务的分类法和BI云系统的体系结构框架。本文概述了参考体系结构。

Mostly the patch antenna creates the focus of the researchers. Multiband but single feed microstrip antenna has been proposed in this work. It is of Z-shape with I-slot antenna that operates at 3.5 GHz and 4.3 GHz which can be used for Wi-Max/S-band &C-band satellite applications. As the radiating edges of the antenna are cut by the slot, the multiple frequency response is generated. In this Z-shape antenna I-slot has been created on the radiating edge for which dual frequency response is achieved. The return losses at 3.5 GHz and 4.3 GHz are -18.88 dB and -16.42 dB respectively. Its bandwidth is of 140.7 MHz (lower band) to 131.5 MHz (upper band). A pair of slits has been inserted in the radiating edge to form Z-shape patch antenna and improved the performance. The proposed antenna designed in this paper exhibits enhanced bandwidth with multi resonant frequency. In this work, a geometric Z-shape is developed from a rectangular patch of width (W = 38.04 mm) and length (L = 29.44 mm). The antenna is designed using FR4-epoxy substrate with a dielectric constant ( of 4.4 and a thickness of 1.6 mm respectively. The result of proposed antenna is obtained in terms of return loss and bandwidth. Its radiation patterns are also studied. The simulated result shows that the Z-shape patch antenna with I-slot has the highest bandwidth in comparison with patch and Z-shape.
在当前情况下,对无线通信的需求迅速增长。随着技术的发展,对天线的研究要求也越来越高。贴片天线成为研究人员关注的焦点。本文提出了一种多波段单馈电微带天线。它呈z形,带有i槽天线,工作频率为3.5 GHz和4.3 GHz,可用于Wi-Max/ s波段和c波段卫星应用。由于天线的辐射边缘被槽切割,因此产生多重频率响应。在这种z形天线中,在实现双频响应的辐射边缘上创建了i槽。3.5 GHz和4.3 GHz的回波损耗分别为-18.88 dB和-16.42 dB。带宽范围为140.7 MHz(下频段)~ 131.5 MHz(上频段)。在辐射边缘插入一对狭缝,形成z型贴片天线,提高了性能。本文设计的天线具有多谐振频率增强的带宽。在这项工作中,从宽度(W = 38.04 mm)和长度(L = 29.44 mm)的矩形斑块发展出几何z形。天线采用介电常数为4.4、厚度为1.6 mm的fr4 -环氧基板设计。对天线的回波损耗和带宽进行了分析。对其辐射模式也进行了研究。仿真结果表明,与贴片和z形贴片天线相比,带i -槽的z形贴片天线具有最高的带宽。
