There are several possible places which are accessible in many buildings and facilities, various types of systems have been utilized such as access control or surveillance depending on the purpose. Especially if security is important, it must go through the various authentication procedures when people can access. Until now many access control systems have been proposed and developed, they are applied and utilized to companies which security is needed. However, as time passes the problems with existing access control systems occur or the vulnerabilities related to access control are reported, as technology advances. The solution to this, we propose authentication technology related to access control using LED-QR tag.
在许多建筑物和设施中有几个可能进入的地方,根据目的使用了各种类型的系统,例如访问控制或监视。特别是在安全性很重要的情况下,当人们可以访问时,它必须经过各种身份验证过程。到目前为止,已经提出和发展了许多门禁系统,它们被应用和利用到需要安全的公司。然而,随着时间的推移,随着技术的进步,现有的门禁系统出现了问题,或者出现了与门禁相关的漏洞。针对这一问题,我们提出了基于LED-QR标签的门禁相关认证技术。

The necessity to distribute energy wirelessly has been spurred by the tremendous growth in the use of portable devices. Mobile devices have become ubiquitous and the circuits within them have been optimized to consume extremely low amounts of power. Such portable electronic sets are in constant use and the frequent need to recharge them; using conventional wired mechanisms have hindered the mobility of users. Wireless transmission of energy to power-up devices has been proposed since the days of Tesla and since then many theories and methods have been invented. This paper discusses some of those techniques briefly.

Home Entertainment system is recently being offered by Home Theater & Smart TV with contents service. Also, console game is being played in the media like in TV. The usage of 4D as the main technology in entertainment industry has mostly been limited in Theme Park, Amuse Park, Theater, and contents for Movie and Animation. Some simulation systems for game has been developed but they were made mostly by using electric or hydraulic motion system which cause high power consumption and have a restriction of place for install. The paper is attempted to build Home Entertainment system which makes users feel realistic contents by developing 4D systems for Home Entertainment rather than before. 4D control S/W in which user can insert and edit 4D effects on contents of all areas such as game, movie, and broadcasting is developed. Also, built-in pneumatic cylinder in 4D system which can be easily controlled and managed in home is developed.
最近,家庭影院和智能电视推出了提供内容服务的家庭娱乐系统。此外,主机游戏也开始在电视等媒体上播放。4D作为娱乐产业主要技术的使用,大多局限于主题公园、娱乐公园、剧场、电影和动画内容。目前已经开发了一些游戏仿真系统,但大多采用电动或液压运动系统,耗电量大,且安装位置受限。本文试图通过开发4D家庭娱乐系统,而不是以往的4D家庭娱乐系统,来构建能够让用户感受到真实内容的家庭娱乐系统。开发了4D控制系统,用户可以在游戏、电影、广播等各个领域的内容上插入和编辑4D效果。同时,还开发了四维系统内嵌式气缸,便于家庭控制和管理。

The interaction between wireless sensors such as Internet of Things (IoT) and Cloud is a new paradigm of communication virtualization to overcome resource and efficiency restriction. Cloud computing provides unlimited platform, resources, services and also covers almost every area of computing. On the other hand, Wireless Sensor Networks (WSN) has gained attention for their potential supports and attractive solutions such as IoT, environment monitoring, healthcare, military, critical infrastructure monitoring, home and industrial automation, transportation, business, etc. Besides, our virtual groups and social networks are in main role of information sharing. However, this sensor network lacks resource, storage capacity and computational power along with extensibility, fault-tolerance, reliability and openness. These data are not available to community groups or cloud environment for general purpose research or utilization yet. If we reduce the gap between real and virtual world by adding this WSN driven data to cloud environment and virtual communities, then it can gain a remarkable attention from all over, along with giving us the benefit in various sectors. We have proposed a Pub/Sub-based sensor virtualization framework Cloud environment. This integration provides resource, service, and storage with sensor driven data to the community. We have virtualized physical sensors as virtual sensors on cloud computing, while this middleware and virtual sensors are provisioned automatically to end users whenever they required. Our architecture provides service to end users without being concerned about its implementation details. Furthermore, we have proposed an efficient content-based event matching algorithm to analyze subscriptions and to publish proper contents in a cost-effective manner. We have evaluated our algorithm which shows better performance while comparing to that of previously proposed algorithms.
物联网(IoT)等无线传感器与云之间的交互是克服资源和效率限制的通信虚拟化新范式。云计算提供了无限的平台、资源和服务,几乎涵盖了计算的所有领域。另一方面,无线传感器网络(WSN)因其潜在的支持和有吸引力的解决方案而受到关注,如物联网,环境监测,医疗保健,军事,关键基础设施监测,家庭和工业自动化,运输,商业等。此外,我们的虚拟群体和社交网络是信息共享的主要角色。然而,这种传感器网络在可扩展性、容错性、可靠性和开放性等方面缺乏资源、存储容量和计算能力。这些数据还不能提供给社区团体或云环境用于一般目的的研究或利用。如果我们将这些WSN驱动的数据添加到云环境和虚拟社区中,从而缩小现实世界与虚拟世界之间的差距,那么它将得到各方的极大关注,并在各个领域给我们带来好处。提出了一种基于Pub/ sub的传感器虚拟化框架云环境。这种集成为社区提供了带有传感器驱动数据的资源、服务和存储。我们将虚拟物理传感器作为云计算上的虚拟传感器,而中间件和虚拟传感器则在终端用户需要时自动提供给他们。我们的体系结构向最终用户提供服务,而不关心其实现细节。此外,我们还提出了一种高效的基于内容的事件匹配算法来分析订阅并以经济有效的方式发布合适的内容。我们对我们的算法进行了评估,与之前提出的算法相比,我们的算法表现出更好的性能。

With the spread of various kinds of cameras such as digital cameras and DSLR and a growing interest in high-definition and high-resolution images, a method that synthesizes multiple images is being studied among various methods. High Dynamic Range (HDR) images store light exposure with even wider range of number than normal digital images. Therefore, it can store the intensity of light inherent in specific scenes expressed by light sources in real life quite accurately. This study suggests feature points synthesis algorithm to improve the performance of HDR panorama recognition method (algorithm) at recognition and coordination level through classifying the feature points for image recognition using more than one multi frames.

This study proposes a sports simulation device with various harmonics generation. The proposed system is composed of 6 degrees of freedom simulator devices and three types of sports simulation such as walking, snowboard, and jet-ski. In this research, every joint movement is designed with a crank-and-slider mechanism, which is efficient for generating continuous curvature smoothly. Contrary to the conventional spatial simulator with linear actuators, harmonics generation and its spatial combinations become the crucial issue in this research. The harmonic pattern in each joint is modelled for generating smooth curvatures that are also superposed for achieving overall motions. In addition, the targeted motions of sports simulations have different physical factors of periodic gait motion, frictionless surface, and buoyant effects, which are respectively designed by integrating three dimensional graphics information.

Digital filters are extensively used in the world of communication. In order to design a digital finite impulse response (FIR) filter that satisfies all the required conditions is challenging. In this paper, design techniques of digital low pass FIR filters using Rectangular window method, Hamming window, Hanning window, and Optimal Parks McClellan method are presented. The stability, number of components required and filter coefficients are demonstrated for different design techniques. It is demonstrated that filter design using hamming window is comparatively better than rectangular and hanning window though the components required for all of the windowing technique are same, hamming shows higher stability. The stability is shown with the help of magnitude and phase spectrum of each window. Simulation is carried out using MATLAB and comparisons are made entirely based on the output of the simulation.
数字滤波器广泛应用于通信领域。为了设计一个满足所有要求条件的数字有限脉冲响应(FIR)滤波器是具有挑战性的。本文介绍了矩形窗法、汉明窗法、汉宁窗法和最优帕克斯麦克莱伦法的数字低通FIR滤波器设计技术。在不同的设计技术下,论证了稳定性、所需元件数量和滤波器系数。结果表明,采用汉明窗的滤波器设计相对于矩形窗和汉明窗的滤波器设计要好,尽管所有开窗技术所需的元件相同,但汉明窗具有更高的稳定性。利用各窗口的幅值谱和相位谱来表示其稳定性。利用MATLAB进行仿真,完全根据仿真输出进行比较。
