Abstract

This paper presents the experiments and makes a research on Effective User interface design of a Multimedia learning system. An experiment has been conducted to study the use of 3D Animation in the effective user interface design. The purpose of the research reported in this paper was to find out the use of 3D animation for developing an effective user interface design. It has been realized that there is a strong need for voice support, text and 3d animation for the effective user interface design to put the system highly utilizable and practicable. We have used Autodesk MAYA software learning edition to develop the multimedia learning system. This research examines the usability of multimedia learning system improvement with the help of usability analysis checklists. The ultimate objective of this study is to bring out the users understanding level and comforting level as well as satisfaction level due to the presence of 3d animation and attractive graphics for a multimedia learning system.

Abstract

This paper presents the experiments and makes a research on combining 3D animation with Sound material for effective learning of Information Technology subject among the adult learners between the ages 20 to 30. This paper proposes to make use of Autodesk 3D Studio Max animation software technologies to learn IT and then generate learning materials according to software features. Autodesk 3D Studio Max 2010 released by Autodesk University (USA) is a kind of animation software. It has features of being powerful entertainment animation capability and easily integrates with other 3D software. Therefore, it is used by many animation colleges in India. On the above of experiment, the paper introduces an approach on how to simplify the IT learning method. It also finds a solution on how to use and integrate Autodesk 3D Studio Max learning materials with the current learning platform seamlessly for better learning. The purpose of the research reported in this paper was to find out the usefulness of 3D animated learning material for supporting Information Technology learners between the age groups 20 to 30.

Abstract

This study sought to explore the effects of 3D animation and support requirements of Digital Media on adult‟s learning. This experiment also presents the relationships between Attitude Quotients (A.Q.), Personality and Multimedia 3D Animations among the BSc Visual communication students. An experiment has been conducted to study the relationship between studying Attitude Quotients, Personality and multimedia learning materials‟ impact on the Retention and Recollection ability among the students. To provide an effective and interesting visual communication learning experience, the multimedia 3D animation tool is proposed. Based on the visual perception impact concept, learning through a 3D animation or simple 3D multimedia learning system allows students actively engage in the learning process. purpose of the research reported in this paper was to find out the use of 3D animation for developing an effective learning material. The ultimate objective of this study is to bring out the students‟ cognitive aspects such as studying attitude Quotients, Personality differences recollection level and retention level due to the presence of 3D animation in a multimedia learning material. We have investigated the visual, audio and music impact among the students‟ cognitive style. We have found that there are relationships exits between students‟ attitude quotient, personality difference and learning materials‟ various attributes like Colour, Sound, Audio, 3D images and 3D animation.

Abstract

Background: Cognitive radio is being recognized as an intelligent technology due to its ability to rapidly and autonomously adapt operating parameters to changing environments and conditions. In order to reliably and swiftly detect spectrum holes in cognitive radios, spectrum sensing must be used. Accurate spectrum sensing is important in improving the efficiency of cognitive radio networks. False sensing results in either waste of spectrum or harmful interference to primary users who may remotely or physically capture the sensors and manipulate the sensing reports. Methods: A novel framework and an innovative approach have been introduced to eliminate the malicious behaviors of secondary users. It is found that spectrum sensing alone cannot prevent the malicious behavior without any information on users’ reputation. Based on the evaluation of malicious behavior resistance methods, joint spectrum sensing and malicious nodes detection approach for optimal prevention from sensing falsification is being proposed. Findings: The proposed approach minimizes Linear Minimum Mean-Square Errors (LMMSEs) when it is compared with the existing algorithms such spectrum sensing based on HSMM and FNN based spectrum sensing are plotted versus detection probability, false alarm probability. With more malicious nodes proposed schemes are more effective to restrain the false alarms. Improvement/Application: The proposed spectrum sensesframework with attack detection which is very effective to determine the malicious users in spectrum holes.

Abstract

Powder metallurgy remains a promising route for the manufacturing of Metal Matrix Composites (MMCs) with desirable properties, in this paper an attempt has been made to manufacture MMCs through powder metallurgy route and compression testing was performed on the MMCs. The aluminum (99% pure aluminum) metal matrix composites with 15% volume fraction of SiC (green bonded 25m size) were produced through powder metallurgy technique. The mixture of composite powders with graphite binder was first cold pressed and then vacuum hot pressed to attain the required density. The green compacts were further sintered in vacuum atmosphere to produce MMCs. The specimens 20 mm diameter by 20 mm length were hot pressed for a range of temperatures (300 -5007C), strains (0.1 -0.5) and strain rates (0.0087 /s to 2.7 Is). The true stress-true strain curves were drawn for the different testing conditions. Strain rate sensitivity, power dissipation efficiency, and instability parameter were estimated and processing maps were developed for 0.1 and 0.5 strains for AiH5% SiC composites. The optimum working regions were identified and validated through microscopic examination.
