  • This paper describes a framework for multimodal object manipulation in virtual environments. The gist of the proposed framework is the semantic integration of multimodal input using spatial ontology and user context to integrate the interpretation results from the inputs into a single one. The spatial ontology, describing the spatial relationships between objects, is used together with the current user context to solve ambiguities coming from the user's commands. These commands are used to reposition the objects in the virtual environments. We discuss how the spatial ontology is defined and used to assist the user to perform object placements in the virtual environment as it will be in the real world.

  • This paper proposes a 3-screen multi-function console development method using ergonomic design approach. Ergonomically designed console has the advantage of decreasing operator fatigue and increasing concentration by providing better readability, operability and convenience. For this, thirty subjects participated in the experiment for 3-screen multi-function console design. Ergonomic standards of console design were used to establish experiment design and to eliminate incompatible results with ergonomic standards. Subjects evaluated the nine predefined placements of displays and asked to place the display and controllers in order to use comfortably. As a results, total 18 design criteria including displays and controllers placement were determined.

Research design, data, and methodology - It is a descriptive type of research in nature. Questionnaire Based Survey has been used to collect the data. The sample size for the study is 500 comprising of the students respondents. The sample has been taken randomly and the questionnaire was filled by the students (pursuing B. Tech) chosen on the random basis from a private technical educational institution in NCR, Haryana, India. For data analysis and conclusion of the results of the survey, statistical tool like F test was performed with the help of high quality software; SPSS. Conclusion - Analysis of variance revealed statistically no difference between the mean number of the groups (stream wise) for the parameters "Selection", "Academic Excellence", "Infrastructure", "Personality Development and Industry Exposure" and "Management and Administration". While Analysis of variance revealed statistically difference between the mean numbers of the groups for the parameter "Placements".

  • This paper proposes a design of IIR notch filter with modified pole placements. The pole angle is derived from quadratic programming to find the appropriate pole position on the unit circle in z-plane in order to achieve the symmetry of the amplitude response. The simulation results are shown when compared with the conventional design technique. Moreover, it uses the TMS320C31 DSP chip for hardware implementation. Finally, the hardware implementation can be applied to removal of ECG baseline wander and elimination of AC power line interference in ECG signal.

  • In early stages of film or animation production, storyboard is used to visually describe the outline of a story. Drawings or photographs, as well as the texts, are employed for character / item placements and camera pose. However, commercially available storyboard tools are mainly drawing and editing tools, not providing functionality for item placement and camera control. In this paper, an Augmented Reality based storyboard tool is presented, which provides an intuitive and easy-to-use interface for storyboard development. Using the presented tool, non-expert users may compose 30 scenes in his or her real environments through tangible building blocks which are used to fetch corresponding 3D models and their pose.

  • RC structure which is located at shoreline has more serious damages compared with inland structure, because it is directly exposed to chlorine ion which is called incoming salt. In the transmission of incoming salt, differences in transmitted volume of incoming salts could occur according to the influences of local shoreline topography which includes surrounding weather conditions, types of building placements, obstacles of wind tunnel etc. And therefore, for the application of boundary conditions for durable offshore structure design against the salt attack, comparative analysis through wind tunnel test and fluid value simulation are executed in order to investigate the moving and adhesion process of incoming salt to offshore structure.

  • An efficient automatic mesh generator suitable for the harsh model, which contains abrupt regions and thin layers, is implemented. It adopts two kinds of node placement scheme. In the beginning, the initial nodes on the boundary are generated automatically by an efficient boundary node generation scheme. And then the inner nodes are placed using nodal spacing value technique repeatedly from the initial mesh to final mesh. The effectiveness of the proposed technique is verified by a thin film micro-strip line modeling, where the final mesh contains no sliver elements.

  • Performance bottleneck of parallel computer systems has mostly been I/O devices because of disparity between processor speed and I/O speed. Therefore I/O node placement strategy is required such that it can minimize the number of I/O nodes, I/O access time and I/O traffic in an interconnection network. In this paper, we propose an optimal distance-k embedding algorithm, and analyze its effect on system performance when this algorithm is applied to n x n torus architecture. We prove this algorithm is an efficient I/O node placement using software simulation. I/O node placement using the proposed algorithm shows the highest performance among other I/O node placements in all cases. It is because locations of I/O nodes are uniformly distributed in the whole network, resulting in reduced traffic in the intE'rconnection network.

  • Restructuring and recent developments in the power system and problems arising from construction and maintenance of large power plants, increasing amount of interest in distributed generation (DG) source. Distributed generation units due to specifications, technology and location network connectivity can improve system and load point reliability indices. In this paper, the allocation and sizing of DG in distribution networks are determined using optimization. The objective function of the proposed method is to improve customer-based reliability indices at lowest cost. The placement and size of DGs are optimized using a Genetic Algorithm (GA). To evaluate the proposed algorithm, 34-bus IEEE test system, is used. The results illustrate efficiency of the proposed method.

  • In this paper, we implement a multi-touch system using FIDR. The implementation consists of hardware manufacture and development of image processing system. In the hardware system, touch screen, infrared LED placements and infrared camera are made. The image processing procedure is to extract each pointer's coordinates from image data and includes binary-coding, noise-elimination, labeling and calculation of mass center. From the implementation, we are able to make a multi-touch system with considerably lower cost than the existing ones.
