The paper presents the simulation studies on a cascaded H-Bridge converter based DSTATCOM for power factor improvement in power distribution set-up using load side compensation. In this novel control strategy, load reactive current is monitored and set as a reference for DSTATCOM controller in such a way that DSTATCOM is able to supply the reactive power demanded by the load both during steady state and transient conditions.

Both calibrated and uncalibrated camera systems are considered, and a performance index in the form of the integral of the error covariance of the reconstructed images, is suggested. In the uncalibrated case image reconstruction is only possible only up to the orbits of the projective linear group, and in this case we treat the covariance as a two tensor on the projective space. We also discuss the case of three dimensional camera motion under the Lising's constraints, and show how to extend planar results to this case.","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126080567","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}

To authenticate a group of users and to hold confidentiality between them a new approach of key management is handled in this paper. This key management presentation is a group key used for cryptography process that provides security with less computation complexity, which leads to fast and easy authentication. Here, a tree based key management scheme has been designed through which the key distribution among the users involves authentication with less storage complexity too. This paper describes the dynamic membership authentication, which states the communication or transaction between user and required server with a new different instant key that is formed from a group of members who are currently participating in transaction or communication. Releasing or joining a user from the group or to the group is possible so that the key gets changed instantly whenever there is an alteration in current participation of users in communication. With the help of each user's hidden key an `instant key' can be computed. As the entire user's hidden keys are used for obtaining an instant key, it can ensure the authentication among the valid users during communication. So an intruder cannot interrupt any communication between users as the key gets varied often. Thus it supports clear authentication and provides security among group communication","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123577203","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}

There are several mechanisms, standards and protocols to achieve non-repudiation in techno-information environment.

Lack of efficient non-repudiation in the legal framework for techno-information environment makes legal issues when evidence is generated maintained. It can be derived that traditional non-repudiation mechanism delivers efficient non-repudiation. Efficient non-repudiation in techno-information environment is achieved by mapping traditional non-repudiation.

Two modules were developed for power line communication and wireless communication where users can select the channel on their choice. The central location and all the energy meters in the network were connected in bus topology. Each energy meter was given a unique identification number by which the central data acquisition server identified each of it. A communication protocol was developed in such a way that it would communicate one meter at a time. Time division multiplexing was used to eliminate the collisions and to obtain a reliable transmission. A microcontroller functions as the main processing element of this product. It was programmed in such a way that it would measure energy and transmit the measured values through a specified channel. The designed meter was not only capable of measuring electricity, but also capable of monitoring parameters like voltage, current and power factor.

The software model is tested for its performance in terms of entropy, standard deviation. The memory and silicon area constraints play a vital role in the realization of the hardware for hand-held devices.

Today learning is open to everyone. Knowledge acquisition is not restricted to vertical sources such as schools and colleges. Educational view point is to ensure that the learner has acquired knowledge through any means to ensure required levels of competencies. A learner may have acquired some knowledge without developing any analytical skills, effort to commit to learning or the ability to maintain a continuous process of learning. More seriously, the learner may not have developed adequate enthusiasm about a subject though it appears as if the learner has learned. From the educational viewpoint these are crucial issues that need to be addressed. As such measuring the development of mental attributes associated to a learning process is of great importance. Student learning styles vary enormously. Not all students respond positively to the same teaching techniques. Used well, learning technology can help turn the learning environment into a highly interactive, stimulating world where the student is totally embedded in the learning process. Learning technology can offer students control over their learning and flexibility, so that they can learn in the style that is most effective for each individual","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123649408","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}

Signell","doi":"10.1109/ICIIS.2006.365772","DOIUrl":"https://doi.org/10.1109/ICIIS.2006.365772","url":null,"abstract":"Digital video broadcasting-terrestrial (DVB-T), the European terrestrial digital TV system, is becoming popular in the broadcaster community around the world. Many countries have started terrestrial digital TV broadcast and are planning to switch-off analogue broadcasts in near future. A new set of services on DVB systems would be the key to sustain its successful commercial deployment. DVB-return channel terrestrial (RCT) is a complementary standard for DVB-T which defines an interactive return channel using UHF/VHF bands. Together, DVB-T/RCT system provides a bi-directional, asymmetric, broadband wireless path between broadcasters and customers, which leads to a true terrestrial wireless interactive system. A host of interactive services are possible on such a platform including IP services. This make DVB-T/RCT a cost effective solution for providing Internet access in rural areas where the telecommunication infrastructure is not fully developed but are already covered by the terrestrial broadcast networks. In this paper, software implementation of the DVB-RCT terminal (DVB-RCTT) is presented which was carried out as a master thesis work. In conjunction with two other master theses, the goal was to develop a prototype of DVB-RCTT for testing purposes at DVB-T/RCT test-bed in Sweden. The prototype consists of a PC running GNU/Linux, a PCI DVB-T card for the receiver and a PCI FPGA board for the modulator of the RCTT. The focus of the software implementation is on the medium access control (MAC) layer of the DVB-RCTT to be executed on the GNU/Linux box. First, the MAC messaging sequences between base-station and terminal at the DVB-T/RCT test-bed were studied. A DVB-RCT MAC message analyzer was developed initially for this purpose. Based on the analysis, MAC layer for a prototype of RCTT is developed under Debian GNU/Linux OS. In order to facilitate the MAC layer communication with the RCT modulator, DVB-API is extended to the support the modulator functionality. The new DVB-RCT modulator API is implemented as a hardware independent device driver under GNU/Linux. The MAC process was tested against messaging sequences obtained at DVB-T/RCT test-bed to verify correct functionality","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115867261","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}
