Therefore, it requires more and more generating facilities connected to the national grid. Since, all most all the economically feasible hydro potentials are captured, the utilities are more concerned on other source of electricity generation. The fossil fuel based electricity generation does not provide a sustainable solution, since the world's fossil fuel resources are depleting at a rapid pace. Another major problem with conventional fossil fuel based electricity generation is the emission of both air pollutants and green house gases. Therefore, in the recent past renewable energy based electricity generation has drawn an increased attention in worldwide. Among the renewable energy sources available in Sri Lanka, wind power has been identified as the most promising option for grid connected electricity generation. However, wind power development in Sri Lanka is not at a satisfactory level and it has some technical, logistical as well as policy constraints.

This dynamic scheduler is designed for uplink VBR multimedia services with constraint QoS. An admission controller is also included in the system to avoid the system overload. The performance of the dynamic scheduler at the BS is analyzed with various uplink schedulers at the SS. The simulation is carried out for various scenarios and the system performance is evaluated.

Similar to our five senses - sight, sound, smell, taste and touch - correspondingly visual/optical, acoustic/ultrasonic, electrical, chemical and thermal/magnetic sensors have been developed. The response from these primary sensors is converted to electrical signals, which are transmitted to the brain (central processing unit) for further processing. In addition to the processing, the role of the processor is to make decision based on these inputs. This is currently done manually by an experienced operator who has an understanding of the sensing and processing technology. To aid the operator in making a more judicious decision, the conditioned signal has to be presented with as much pertinent information displayed in an arresting way. A further development would be to provide the virtual machine itself to make the judgment - smart sensor. The next stage in this would be for the processor to decide on the course of action and the actuation mechanism to respond accordingly. Virtual human robots can be equipped with sensors, memory, perception, and behavioral motor. This eventually makes these virtual human robots to act or react to events. The design of a behavioral animation system raises questions about creating autonomous actors, endowing them with perception, selecting their actions, their motor control and making their behavior believable and the behavior should be spontaneous and unpredictable","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"1 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":"129742073","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}

Hence, recently we proposed a minimum mean-square error (MMSE)-based turbo equalization scheme for the ST block coded CDMA downlink. In the proposed scheme, we assumed that perfect channel information is available at the receiver. However, in practice, channel coefficients are unknown to the receiver and have to be obtained through channel estimation. In this paper, we investigate the effect of the channel estimation errors on the MMSE-based turbo equalization in the downlink of ST block coded CDMA systems.

Humanoid robots are without question a hot topic in research today. But will they really be the next break-through invention that changes the face of the world. For decades, popular culture has been enthralled with the possibility of robots that act and look like humans. We are promised by film, fiction and television that humanoids will cook for us, clean for us, become our best friends, teach our children, and even fall in love with us. Recently, the media has covered a surprising number of new humanoid robots emerging on the commercial market. Like many new technologies, these early generations of commercially available humanoids are costly curiosities, useful for entertainment. Yet, in time, they accomplish a wide variety of tasks in homes, battlefields, nuclear plants, government installations, factory floors, and even space stations. Humanoids may prove to be the ideal robot design to interact with people. Humanoid robotics also offers a unique research tool for understanding the human brain and body. Already, humanoids have provided revolutionary new ways for studying cognitive science. Using humanoids, researchers can embody their theories and take them to task at a variety of levels. Aside from their traditional roles, humanoid robots can be used to explore theories of human intelligence. This paper reviews a wide variety of humanoid robots being used throughout the world and explaining its typical applications and future challenges while developing humanoid robots which may come across such endeavours. This paper would review successes and failures in the field where humanoid research began. Further, an extrapolations of recent developments is also given where it may take us in the future.

ILJc would be the middle-base in compiling and translating the IL code which ports out of Microsoft Visual Studio.NET into the equivalent Java byte code. Thus, ILJc would simply transform Visual Studio.NET into relative Java applications. ILJc does its best to map Microsoft.NET entities to Java equivalents, furthermore ILJc must deal with the exceptions too. For an instance, in the case of exceptions, Java provides one exception class, but Microsoft.NET provides three; ILJc is forced to map all three Microsoft.NET exceptions to the single Java exception. The task is no easy to fix, but simply have to write around this many-to-one mapping. Although all Microsoft.NET exceptions are derived from the system.exception class, not all Java exceptions are derived from Java.lang.exceptions; some generated by the JVM (Java virtual machine) are derived from the Java.lang.error class. This incongruence shows up in Microsoft.NET code that tries to catch all exceptions, when translated into Java, exceptions derived from Java.lang.error is taken for granted and slip off. As a proof of concept of how that system could be, we started sometime ago to implement ILJc, featuring a modular, flexible architecture.
