Intelligent interaction systems will work in synchronization with existing powerful computers to create, a robust force in making human computer communication effortless. It's said that \"Simplicity is the ultimate Sophistication. So our proposed intelligent interaction system will be very simple and it can be defined as \"Perpetual Search Engine. It will be supplemented with the devices as Natural user interfaces (with the abilities of \"Text/Image/Object/Audio recognition) and Web 2.0 compliant powerful presentation layer (such as adobe flex along with relevant hardware). The \"Perpetual Search Engine would not store/process any data but it will provide user the ability to plug-in the respective devices if user needs. It would just interface with the Natural user interface devices and pass the data to remote server computer which will process data with handling of personalization, demonstration and return the output to \"simple client which would just display output with its powerful presentation layer. For example, please imagine that a doctor screens patient's bruise on the \"Perpetual Search Engine using an interfaced camera and gets his diagnosis quickly. Next minute, the doctor writes name of the medicine on screen using a pencil and gets the details which will be printed. Another example of powerful presentation layer is \"viewing your search results in the system. The user won't need spectacles to see the results with small font as screen would adjust font size from the analysis of the reflections of light rays from the lenses of user's eyes. The reflection would show whether the lenses are able to focus in normal way. If lenses function abnormally, font will be increased/decreased for getting proper results. So in essence, every Human-Computer interaction will be treated as a \"Search operation which will be supplemented with the \"Powerful presentation layer and \"Natural user interfaces. This is the unique idea of our proposed system.","PeriodicalId":197580,"journal":{"name":"International Conference & Workshop on Emerging Trends in Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130471639","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}

For the students, ClassroomWiki provides a web interface for writing and revising their group's Wiki and a topic-based forum for discussing their ideas during collaboration. When the students collaborate, ClassroomWiki tracks all student activities and builds detailed student models that represent their contributions toward their groups. For the teacher, ClassroomWiki provides a multiagent framework that uses the student models to form student groups to improve the collaborative learning of students. ClassroomWiki can improve the collaborative learning outcome of the students by its group formation framework and help the teacher better assess a student's contribution toward his or her group.

It is made from non-toxic, biodegradable, renewable resources. Biodiesel can be produced in many ways. The method used in the laboratory was transesterification which is actually replacement of alcohol group from an ester by another alcohol. The reaction was carried out by varying different parameters to find the best conversion of oil to biodiesel. Alkali catalysed transesterification is considered to be the best amongst all methods available for the production of biodiesel from fresh oil. It was found out that the rate of transesterification reaction in a batch reactor increases with temperature. Higher temperatures do not reduce the time to reach maximal conversion. The conversion of triglyceride, diglyceride and monoglyceride appears to be second order upto 10 minutes of reaction time. Our aim is to establish the kinetics of the reaction during transesterification and to do the modeling and predict rate equation for the reaction","PeriodicalId":197580,"journal":{"name":"International Conference & Workshop on Emerging Trends in Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127574088","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}

All-pMOS VCO followed by static frequency divider using source degeneration based D flip-flops is proposed. An accurate small signal analysis model of proposed D flip-flops is provided to estimate the maximum operating frequency of the divider. The advantages of proposed QVCO are analyzed in terms of phase noise and suppress the higher order (≥3) harmonics through linearization. The best overall performance is displayed by the inversion mode pMOS varactor. The proposed QVCO is tuned from 2.4 to 2.5 GHz with a tuning voltage varying from 0 to 1 V, additional 80 MHz increased by switched capacitor array (SCA). Compared to the conventional QVCO without resistor, the proposed QVCO shows good 1/f3 close-in phase noise. The simulated results shows about 6.0 dB, 8.0 dB, 6.0 dB and 0 dB of phase noise improvement at 10 KHz, 100 KHz, 1 MHz and 3 MHz offset frequency from a 2.4 GHz carrier. The input sensitivity of the proposed divider is simulated from 50 mV to 510 mV to achieve the operating frequency varies from 3.0 GHz to 6.2 GHz. The 3rd harmonic distortion is 44 dB less than that of fundamental frequency.","PeriodicalId":197580,"journal":{"name":"International Conference & Workshop on Emerging Trends in Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127586095","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 architecture aims to apply high data rates, quality of services, long range and low deployment costs to a wireless access technology on a metropolitan scale. This paper focuses on WiMAX since this wireless technology allows broadband communications. In particular, we provide here a preliminary study on MAC layer performance as well as a sensitivity study to its parameters. In this paper I have implemented the performance comparison with different WiMAX environment for video application under UGS (Voice over IP (VoIP) without silence suppression) with respect to Throughput, Load and Delay.

The design for minimum blockage condition results in geometry that offers lower amount of blockage and increased spillover past the subreflector. To avoid this, optimized design of the antenna results in geometry that offers lower amount of spillover past the edges of the main reflector and increases some percentage of blockage. The design of feed elements for Cassegrain antennas is considered in the following section. It includes the design of conical corrugated horn antenna having throat section. Throat section is used for the purpose of achieving match between input waveguide and horn thereby maintaining low VSWR. The Scalar Horns are used to obtain identical performance in both the principal planes.
