Recently, Cloud computing has emerged as a new computing paradigm on the Internet. Cloud computing facilitates flexible and efficient computer resource management via virtualization technologies at anytime and from anywhere, so that users can add and/or delete IT resources. Users can set up and boot the required resources and they have to pay only for the required resources. However, they have to...
In this paper, we have prepared a medium size Bangla speech corpus and compare performances of different acoustic features for Bangla word recognition. Most of the Bangla automatic speech recognition (ASR) system uses a small number of speakers, but 40 speakers selected from a wide area of Bangladesh, where Bangla is used as a native language, are involved here. In the experiments, mel-frequency cepstral...
This paper describes an effect of articulatory Δ and ΔΔ parameters on automatic speech recognition (ASR). Articulatory features (AFs) or distinctive phonetic features (DPFs)-based system shows its superiority in performances over acoustic features based ASR. These performances can be further improved by incorporating articulatory dynamic parameters into it. In this paper, we have proposed such a phoneme...
A one degree-of-freedom (vertical up-down) power assist robot was developed for lifting objects. The robot was simulated and six subjects independently lifted objects of three different sizes with the robot. In each trial, the subject used his two hands synchronously to lift the object with the robot and estimated the perceived weight of the lifted object by comparing it to a reference weight. We...
A power assist robot system reduces the weight of an object lifted with it. However, the root causes of the reduced heaviness as well as the factors affecting the heaviness are still unknown. The knowledge on the root causes and factors could be used to modulate the interactions between the human user and the robot when lifting objects with it. This paper investigated the reasons and factors behind...
Classification rules are the interest of most data miners to summarize the discrimination ability of classes present in data. A classification rule is an assertion, which discriminates the concepts of one class from other classes. The most classification rules mining algorithm aims to providing a single solution where multiple solutions exist. Moreover, it does not guarantee the optimal solution and...
Detection and classification of vehicles are the most challenging tasks of a video-based intelligent transportation system. Traditional detection and classification methods are based on subtraction of estimated still backgrounds from a video to find out the moving objects. In general, these methods are computationally highly expensive, and in many cases show poor detection and classification performance,...
The sense of touch has much importance in technology-mediated human emotion communication and interaction. Many researchers around the world are aiming to leverage the sense of touch in the communication medium between multi-user 3D virtual world and real environment. Driven by the motivation, we explored the possibilities of integrating haptic interactions with Linden Lab's multi-user online virtual...
We conducted two experiments. In the first experiment, we made two objects with identical appearance. One was lifted by humans in constrained condition, another was lifted in unconstrained condition, and human's weight perception was compared between the two conditions. The results showed that weight perception for constrained lifting of objects was not too much different from that for unconstrained...

In this research we present a question answering based searching technique for location based shopping. A user may ask a question to the system as they naturally ask to a human while the system retrieves the search results by analyzing the given question and the current GPS location. Based on the retrieved results, the system carry out conversation with the user to explicitly understand his/her needs...
A power assist system reduces the weight of an object lifted with it. But, the human operator cannot differentiate between the perceived weight and the actual weight and eventually applies excessive load force. This faulty force programming (excessive load force) results in faulty motions of the power assist system and jeopardizes its maneuverability, ease of use, naturalness, human-friendliness,...
