The success of e-Discovery depends on how well the litigant and lawyer search relevant evidence, and it is closely associated with making fine queries based on their analysis of complaint and data set. Therefore, this paper proposes a Query Recommending Scheme called QRS for an efficient evidence search in e-Discovery procedure. This scheme is composed with four different phases and various techniques are applied such as document parsing, machine learning and scoring. We describe how QRS works using the flow chart and introduce further researches for the improvement of QRS.","PeriodicalId":6380,"journal":{"name":"16th International Conference on Advanced Communication Technology","volume":"30 1","pages":"1237-1241"},"PeriodicalIF":0.0,"publicationDate":"2014-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86275839","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}

According to their iterative nature, the computational complexity of turbo decoder is much higher than that of convolutional FEC decoders. From the hardware implementation point of view, the complexity can be reduced by using quantized decoder. For DVB-RCS turbo coding, there are many block sizes and different code rates. In order to realize the DVB-RCS turbo decoder efficiently, an algorithm should be developed for the best computation of quantization range for each code rate and at different signal-to-noise ratios. This paper investigates the decoder input quantization of low complexity decoding algorithm and proposes an algorithm for efficient decoder quantization by introducing a scaling factor into the decoding algorithm, aiming to achieve significant improvement in the hardware implementation of the decoder architecture.","PeriodicalId":6380,"journal":{"name":"16th International Conference on Advanced Communication Technology","volume":"103 1","pages":"426-433"},"PeriodicalIF":0.0,"publicationDate":"2014-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77277665","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}

This is because the ultrasonic sensors should be powered at an appropriate timing so as to prevent ultrasonic interference. In this paper, we propose a harmful bird attack system and a new timing synchronization method for ZigBee sensor network. In this timing synchronizing method, by concentrating the processing load to the server, the amount of calculation on each node can be minimized and is unaffected by the increase in the number of nodes. Evaluation of the proposed method has shown that it sufficiently fulfills the timing requirement for the proposed harmful birds attack system.","PeriodicalId":6380,"journal":{"name":"16th International Conference on Advanced Communication Technology","volume":"1 5","pages":"365-370"},"PeriodicalIF":0.0,"publicationDate":"2014-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91440974","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 is difficult for today's inflexible infrastructure to cope with the fast changing demands of the users. As a result, Software-Defined Network (SDN) was introduced around 2005 to transform today's network to have centralized management, rapid innovation, and programmability by decoupling the control and data planes. This study focuses on developing a firewall application that runs over an OpenFlow-based SDN controller to show that most of the firewall functionalities are able to be built on software, without the aid of a dedicated hardware. Among many OpenFlow controllers that already exist for the public, we have chosen POX written in Python for the experiment; and to create the SDN network topology, we have used VirtualBox and Mininet. In this study, we cover the implementation detail of our firewall application, as well as the experimentation result.","PeriodicalId":6380,"journal":{"name":"16th International Conference on Advanced Communication Technology","volume":"1 1","pages":"744-748"},"PeriodicalIF":0.0,"publicationDate":"2014-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90321137","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 is difficult to predict the agricultural crop production because of the abnormal weather that happens every year and rapid regional climate change due to global warming.

In this research, we cover how to process the number of weather data(monthly, daily) and how to configure the prediction system. We establish a non-parametric statistical model on the basis of 33 years of agricultural weather information. According to the implemented model, we predict final production using the monthly weather information.

That kind of programmability is backed by NOS (Network OS), which is usually called SDN controller. A Controller supports network-controlling applications to run on top of it by transparently dealing with the actual communication with the switching devices. However, as the controller is normally centralized, the scalability and availability issue is inevitable: a controller should provide reasonable performance to each of the switching device regardless of the network size, and guarantee the non-stop operation of NOS applications against system and software failures to prevent the whole network from halting on the control plane crashes. In this paper, we investigate the issues deeply, and introduce a comprehensive solution called IRIS (ETRI Recursive SDN controller platform).","PeriodicalId":6380,"journal":{"name":"16th International Conference on Advanced Communication Technology","volume":"14 1","pages":"1227-1231"},"PeriodicalIF":0.0,"publicationDate":"2014-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73561698","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}

Thus, reducing the size of receiver (Rx) and transmitter (Tx) chips plays an plays an important role in designing a small-size optical modules utilized in o/e and e/o converters. Therefore, designing a small-area optical Rx may require intuitive solutions, such as building single-ended Rx and utilizing some of the advantages of differential Rx. Optical Rx should convert optical input signal to voltage output signal and provide sufficient gain and frequency operation for feeding to subsequent blocks including clock and data recovery circuit (CDR) and/or Serializer and Deserializer (SerDes). Therefore, we have designed a small-area transimpedance optical receiver (TIORx) using regulated-cascode (RGC) as an input stage which converts input photocurrent to voltage signal. The RGC block is connected to post amplifying stages to increase the overall transimpedance gain of the TIORx. The post amplifying gain stages utilizes two intersecting active feedback in order to increase the frequency operation in addition to increasing the gain of the proposed TIORx chip. The TIORx module is designed in a 0.13μm CMOS technology and works up to 10 Gbps data rate. The TIORx chip core occupies an area of 0.051mm2 with power consumption of 16.9 mW at 1.3 V. A measured 3-dB bandwidth of 6.9 GHz was obtained for the TIORx module with a transimpedance gain of 60 dBQ.","PeriodicalId":6380,"journal":{"name":"16th International Conference on Advanced Communication Technology","volume":"12 1","pages":"283-289"},"PeriodicalIF":0.0,"publicationDate":"2014-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74724013","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}

We developed a prototype system that can create building component templates by editing fundamental 3D object primitives using the open source CAD software FreeCAD. Once a building component template is created, it will be segmented and analyzed to select the unit shapes that are commonly and frequently used for a variety of component templates, and they will be registered back into the primitive database so that they can be used in creating other templates in the future. Our system provides easy-to-use editing tool that a user can create the shape of the building component and then the system automatically generate a set of parameters necessary to describe the shape.
