The potential VANET applications present diverse requirements. VANET shows unique characteristics and presents a set of challenges. The proposed VANET applications demand reliable and proficient message dissemination techniques. Routing techniques proposed for Mobile Ad-Hoc Network (MANET) do not cater for the characteristics of VANET. The need for novel routing techniques, exclusively designed for VANET has been recognised. This paper analyses different routing techniques proposed specifically for VANET. Unique characteristics of VANET pose challenges to traditional layered architecture where different layers make independent decisions. Mobility, absence of global view of network, random changes in topology, poor link quality and varied channel conditions have encouraged the paradigm shift to cross-layer approach. In order to optimise the performance of VANET, architectures based on cross-layer approach have been proposed by the researchers. The paper also surveys such cross-layer paradigm based solutions for VANET and concludes with an analytical summary.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114895787","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 reduction of tracking time of maximum power from photovoltaic array and to obtain stabilized sine wave with very fast rise time for voltage stability, fuzzy logic control algorithm is implemented with the embedded microcontroller for improved performance as compared to conventional techniques. The system includes a photovoltaic array; a PWM controlled DC-DC, DC-AC converters, sensor circuits and zero crossing detector (ZCD). The designed MPPT controller regulates the converter output voltage by varying modulation index of the PWM pattern using MPPT algorithm and it maximizes the output power extracted from photovoltaic array. This paper discusses the low cost implementation of MPP algorithm in a 8-bit microcontroller using the tools and techniques to generate optimized real time code in C for ATMega8 microcontroller which will demonstrate how maximum power point tracker might provide elegant and efficient solution for increasing the efficiency of a solar system and connection of the extracted energy to grid which is based on experimental results rather than on mathematical models.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116513832","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}

However, there are several issues arise with regard to readiness of Information Technology (IT) or Computer Science (CS) graduates from the point of views of software industry. This perspective causes the supply of graduates mainly in software engineering field seems to be insufficient. The industry claims that the software engineering graduates are not able to meet their requirements in software industry. This is really surprising to the academia that offers software engineering specialisation or related programmes in IT or CS field. This phenomenon creates the gap between industry's requirements and graduates' readiness which indirectly reflects the gap between software engineering education and industry. A number of studies and frameworks are available to ponder the issues on software engineering education and industry. This paper reports the gap between industry's requirements and graduates' readiness in software engineering perspectives to face the real world. From the findings, we conclude that there is a gap due to high demands from the industry in highly skilled fresh graduates. In contrast, future graduates are still lack of confidence and readiness though they specialise in software engineering field that has more job opportunities in IT or CS field.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133739629","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 counter this problem, three solutions are possible: a) making every device dual stack, b) translation, c) tunneling. Tunneling stands out as the best possible solution. Among the IPv6 tunneling techniques, this paper evaluates the performance of two recent IPv6 tunneling techniques: 6to4 and ISATAP. These protocols were implemented on real test bed setup, on Microsoft Windows (MS Windows XP and MS Windows Server 2003) and Linux operating systems. Five to six devices were used to setup the whole test bed. Each protocol was then implemented on the setup using specific configuration commands, available online at various sources. UDP based audio streaming, video streaming, and TCP based ICMP-ping traffic was run. Four different runs of IPv6 traffic were routed over the setup for both IPv6 tunneling protocols. The average of the data was taken to generate graphs and final results. The performance of these tunneling techniques has been evaluated through certain parameters, namely: throughput, end to end delay (E2ED), round trip time (RTT), and jitter.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123433923","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}

These reactors involve a highly complex set of chemical reactions and heat transfers. The high nonlinearity requires an efficient control algorithm to handle the variation of operational process parameters and the effect of process disturbances efficiently. In this paper, Fuzzy logic and Adaptive controllers are compared for advance microwave biodiesel reactor. The process control is complex and nonlinear, the Adaptive control have longer time and unreliability in dealing with the system parameters including temperature, microwave power, liquid flow rate as well as the prediction of chemical reaction. The proposed fuzzy logic control will provide precise temperature control and faster warm-up phase with quicker response to disturbances with minimal overshoot and undershoot where Adaptive control techniques can not meet these extra challenges. A closed loop fuzzy and adaptive controllers are used to automatically and continuously adjust the applied power of microwave reactor under different perturbations.

Indicators for visual discomfort are observed from objectives ii and iii. The fieldwork was a pilot survey in the west facing gallery during high period of daylight distributions (14.00–16.00hr) for a full week in March 2010. Results showed illuminance levels exceeded allowable exposure limits for some showcases. Measured air temperatures were much higher than accepted comfort range especially with opened windows in the afternoon and the RH levels were within the prescribed range. The survey identified the combination of natural daylight and artificial lighting deteriorated the exhibits' conditions through fading, distortion, dirt and dust. The showcases were placed against and opposite the fully opened windows. Thus, the presence of sunlight, daylight and provision for external views in the gallery produced glare and veiling reflections problems on the glass showcases. These situations may demonstrate the need for proper maintenance and appropriate controlled shading system. The evaluation of daylight distributions may serve as future conservation measure for the exhibits.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130081046","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}
