Supporting meetings in Virtual Worlds with enhanced Communication features

With the rapid growth in the use of computer for addressing our day to day needs and the increased use of technology in our daily life, we cannot imagine a day without the use of the internet for our routine needs. Today, without any doubt in our mind we can say that technology has taken over human lives completely. A new era of computing has evolved where computers and the internet have a huge impact on everyone‟s life. A lot of research has been done and is in process for generated tools and devices which will bring the world even closer. It started with telephone in the last century and since then till today there have been huge number of tools and devices that try to give the users who are geographically far away a sense of co-presence. The latest technology making rounds is the Virtual World technology. The popularity and impact of online virtual worlds is worth making a note of. It needs to be seen now, how does it really betters people lives. One such persistent virtual world is Second Life. The number of users and organizations associated with this world is impressive. It provides users with the right amount of collaborative content with a set of communication features. Second Life provides its users with unique meeting support which gives them a sense of co-presence achieved nowhere else. This thesis focuses upon the kind of meeting support, collaborative content and the communication features provided by the virtual world that will allow its users to avoid the need for travel and long distance meetings can be achieved successfully in such an environment. This will help the travel time to be converted to productive office time as well as the costs involved in such meetings can also be reduced drastically. Such kind of meetings will also prove eco-friendly as they will save on fuel consumption and benefit from reduced pollution

Design and validation of a hybrid interactive reference point method for multi-objective optimization

This paper offers a classification of the main representatives of interactive classical and evolutionary methods. After a crossfertilization of these two fields a new hybrid interactive reference point method is designed. The method combines the reference point idea with the relative speed of a (1+1) - EA and is implemented with a graphical user interface. Finally, it is validated on two well-known real-world test problems

A Case Study of Group Processes and Student Evaluation of Teaching

This paper documents a case study undertaken to understand the effect of group processes on student evaluation of teaching (SET). The study used interviews to investigate the experiences of students in a cohort model Master of Science in Accountancy degree program and how those experiences influenced SET. The cohort served as an extreme example in which group processes played out intensely, allowing the researchers better to examine them. The results showed that the participants’ common experience led to frequent discussion about various aspects of the classes and the program. A common topic of discussion was instructor performance. This discussion about instructors, in turn, appeared to affect SET. It also appeared that a mismatching of expectations and realized student–instructor relationships also affected SET

Resonant Raman of OH/OD vibrations and photoluminescence studies in LiTaO3 thin film

Resonant Raman spectra (RRS) of O-H and O-D vibration and libration modes, their combinations and higher harmonics have been observed in LiTaO3 polycrystalline thin films. RRS peaks are superimposed on photoluminescence (PL) spectrum. Monochromatic light from a xenon lamp is used as excitation source. PL spectrum shows two broad peaks, first near the band gap in UV (4.4-4.8eV) and another in the sub band gap region (< 4.0 eV). Band gap PL along with RRS peaks are reported for the first time. Photoluminescence excitation spectrum (PLE) shows a peak at 4.8 eV. Peak positions and full width at half maximum (FWHM) of RRS peaks depend upon the excitation energy. Dispersions of the fundamental and the third harmonic of the stretching mode of O-H with excitation energy are about 800 cm-1/eV and 2000 cm-1/eV respectively. This dispersion is much higher than reported in any other material.Comment: 20 page

Furnace Oil as an Alternative Fuel in Heating Furnace for Bending Plates

This topic is based on the operation of Heating Furnace for the purpose of bending of the plates in the Industry which is used for Tower Manufacturing. The material or the metal used for the Tower manufacturing are Mild Steel (M.S.) Plates.LPG is commonly used as a fuel in the heating furnace for bending operation. As the cost of LPG affects the production, Furnace Oil as an alternative fuel if considered for the heating furnace operation can be used for bending of plates used in Tower manufacturing. Here, as a consideration of fuel will be on the basis o availability, cost, flash point , calorific value etc

Effect of strain on the phase separation and devitrification of the magnetic glass state in thin films of La<SUB>5/8-y</SUB>Pr<SUB>y</SUB>Ca<SUB>3/8</SUB>MnO<SUB>3</SUB> (y= 0.45)

We present our study of the effect of substrate induced strain on La5/8 - yPryCa3/8MnO3 (y = 0.45) thin films grown on LaAlO3, NdGaO3 and SrTiO3 substrates that show large scale phase separation. It is observed that unstrained films grown on NdGaO3 behave quite similarly to bulk material but the strained films grown on SrTiO3 show melting of the insulating phase to the metallic phase at low temperatures. However, the large scale phase separation and metastable glass-like state is observed in all the films despite differences in substrate induced strain. The measurements of resistivity as a function of temperature under a cooling and heating in unequal field (CHUF) protocol elucidate the presence of a glass-like metastable phase generated due to kinetic arrest of the first order transformation in all the films. Like structural glasses, these magnetic glass-like phases show evidence of devitrification of the arrested charge order antiferromagnetic insulator (CO-AFI) phase to the equilibrium ferromagnetic metallic (FMM) phase with isothermal increase of magnetic field and/or iso-field warming. These measurements also clearly show the equilibrium ground state of this system to be FMM and the metastable glass-like phase to be AFI phase
