This paper provides an architectural classification of smart classrooms and discusses the types of technologies used in their implementation. It examines the methodologies being used to make distance learning an exciting experience and as effective as the traditional classroom type education. Furthermore, the paper shows how commonly used smart classroom settings can be extended to a model where a single local class can simultaneously cater to the needs of multiple remote classrooms and presents a workable solution to some of the technical challenges of the model from a practical utilization aspect. It also shows how some of the inherent challenges of the existing smart classroom systems are being managed and identifies physical and practical limitations of multiple classroom architectures for a successful remote lecturing environment.

Short term load forecasting is very essential to the operation of electricity companies. It enhances the energy-efficient and reliable operation of power system. Artificial neural networks are employed for nonlinear short term load forecasting owing to their powerful nonlinear mapping capabilities. These are generally trained through back-propagation, genetic algorithm (GA), particle swarm optimization (PSO) and artificial immune system (AIS). All these algorithms have specific benefits in terms of accuracy, speed of convergence and historical data requirement for training. In this paper a hybrid AIS is proposed, which is a combination of back-propagation with AIS to get faster convergence, lesser historical data requirement for training with a little compromise in accuracy.

Model reference adaptive system (MRAS) represents one of the most attractive and popular solutions for sensorless control of AC drives. However, the performance of this scheme deteriorates when approaching the zero speed zone. This paper presents an experimental evaluation of the performance of MRAS speed observer when working at very low and zero speed. Results are obtained when applied to an indirect vector control induction motor drive in both open loop and sensorless modes of operation. Since the focus here is on operation around and at zero speed under both no-load and loading operating conditions, this represents a useful contribution to the literature. Results show the deterioration in the performance of the estimation scheme at very low and zero speed especially when load is applied.

The growth of broad and traffic and applications using the Internet has been exponential in the past few years. Internet working applications have significantly impacted human lives. The Internet and in particular the lower 2 layers have changed significantly in the past decade or so. To meet the emerging demands of end-users, networks have evolved from a bandwidth intensive and quality sensitive perspective. We discuss new technology choices that have emerged in the past few years and how these would impact network design in the near future. In particular, the colloquium discusses optical metro, access and long haul technologies including WDM and Carrier Ethernet. The technology choices in the optical and data layer have a strong impact on Future Internet design. Based on these technology choices we develop a road-map for Future Internet design and how it would impact services, applications, technologies and communities. We also discuss briefly the Indian broadband scenario from an access and metro perspective.

This paper presents the design of a uniplanar 3-dB hybrid coupler for microwave integrated circuits (MIC) and monolithic MIC (MMIC) applications. The same was developed and tested experimentally using a network analyzer in Sumeru Microwave Communication Lab. Its design and application issues have been widely discussed here with some standard data and graphs. The experimental results for the standard 1.5 lambda circumference uniplanar 180deg hybrid-ring coupler has been found in the standard accuracy range of 3.2 plusmn 0.4 dB coupling, isolation found is greater than 30-dB and the return loss better than 18.2-dB over a 2% bandwidth centered at 1.46 GHz. Also the experimental insertion loss found for this passive component is 0.5 dB at 1.46 GHz. The same has been concluded with its futuristic perspectives for research aspirants and microwave engineers.

ICT plays an indispensable role in the overall development of rural areas, especially in developing economies. There is an urgent need to bring the rural areas into the mainstream by providing them last mile connectivity, especially during natural disasters and calamities, when other modes of communications are severely hampered. This paper describes a low cost innovative solution for providing internet access to rural areas using tethered aerostats, which can easily be relocated. The total cost of this relocatable system was found to be nearly half of that of a conventional fixed tower based system.

The analysis and control of multi-input integrated DC-DC converter is presented in this paper. The integrated converter is essentially a combination of buck and buck-boost converters. However, on account of integration only one inductor is sufficient enough for performing the power conversion. In order to have simple control strategy as well as simpler compensator design a single loop control scheme, voltage-mode and current-limit control, are proposed here for the power distribution. Closed-loop converter performance of this converter is simulated and compared with the theoretical predictions. Experimental measurements are provided for validating the control concept.

Recent advancements in sonographic techniques have led to non-invasive visualization of organs. These advancements demand use of image processing for measurements on the images obtained from different scans. However, accurate measurement of blood flow is usually very difficult inspite of its important role in clinical diagnosis. Hence for better diagnosis by doctors, systems offering fast and accurate measurements are need of the day. Many techniques developed by researchers are available today for measuring such offline data. In this paper a new system that uses image processing techniques to estimate cardiac parameters on a real time basis is discussed. Importantly, this technique offers high resolution measurements and importantly doesn't require catheterization, hence plays an important role in examining parameters like blood flow rate, oxygen need, size of organs and tumors and diameters of vessels. Discussion of the algorithms for estimating the above parameters is made and results for two of the parameters viz. (1) estimation of ratio of left atrial diameter (LA) to aortic diameter (AO) and (2) oxygen content in these vessels is shown. Succinctly, the proposed system gives accurate online data of different cardiac parameters by the use of image processing techniques.

Basic morphological processing i.e. erosion and dilation, often fails to detect various types of defects that may be present in woven fabric, mainly because of the presence of interlaced grating structure of the weft and warp of the fabric. In this paper basic grating structure is optically filtered and then gray scale morphological reconstruction operations are applied for the detection of defects. The results have shown the usefulness of the proposed method during detections of various types of defects in woven fabric, as illustrated by the portions given in this document.
