Since Apriori-like sequential pattern mining techniques requires expensive multiple scans of database.

The term “haptics” arises from the Greek root haptikos, meaning “able to grasp or perceive.” Haptic interaction with computers implies the ability to use our natural sense of touch to feel and manipulate computed quantities. Haptic computer interaction is a relatively new field that has generated considerable interest over the past decade. Initially, computers could deal only with numbers. It took many years to realize the importance of operating with text. The introduction of CRT display technologies allowed graphics to be displayed, giving us a new way to interact with computers. As processing power increased over time, three-dimensional (3D) graphics became more common and we may now peer into synthetic worlds that seem solid and almost real. Likewise, until recently, the notion of carrying on a “conversation” with our computer was far-fetched. Now, speech technology has progressed to the point that many interesting applications are being considered. Just over the horizon, computer vision is destined to play a role in face and gesture recognition. It seems clear that as the art of computing progresses, even more of the human sensory palette will become engaged. It is likely that the sense of touch (haptics) will be the next sense to play an important role in this evolution. We use touch pervasively in our everyday lives, and are accustomed to easy manipulation of objects in three dimensions. Our working definition of haptics includes all aspects of information acquisition and object manipulation through touch by humans, machines, or a combination of the two; and the environments can be real, virtual or teleoperated. This is the sense in which substantial research and development in haptics is being pursued around the World today","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116239527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, such mobile sensory nodes can be of paramount importance in conducting surveillance and rescue operations for post-disaster recovery teams. The key issue here is to design locomotion and path-planning strategies for bots such that they can operate even in regions with limited or intermittent network connectivity. In this paper, we adapt a variant of the much popular chemotaxic movement algorithm as prevalent amongst bacteria of most strains. Using such a movement strategy the bacteria gradually move towards their location, in search of food, following a chemical gradient. Suboptimal paths are periodically rejected using a process referred to as \"tumbling\". Using such stochastic techniques, even simplistic creatures like the bacteria reach optimal resources with little inter-communication. This paper analyses and demonstrates such a chemotaxic strategy and explains its analogical relevance in the context of target finding in miniaturized mobile sensory nodes. The paper also throws light on how future resource-aware variants of similar algorithms can be utilized to further optimize path planning strategies for such miniaturized ant-like bots.","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125365472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Orthogonal frequency division multiplexing (OFDM) is an effective technique for the future 4G communications because of its great immunity to impulse noise and intersymbol interference. Ultra wide band (UWB) wireless technology is poised to replace high-speed data cables in homes and offices. UWB technology will be capable of transmitting hundreds of megabits per second over distances of several meters. Channel estimation in OFDM systems can conveniently be done by inserting a stream of pilot symbols at the transmitter and by using FIR interpolation filters at the receiver. One of the challenges in wireless system is the frequency selective fading caused due to multipath channel between the transmitter and receiver. To overcome such a multipath fading environment with low complexity and to increase the performance, this paper presents an importance of UWB OFDM for wireless fading channels.","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117172886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

K-means is implemented using standard Euclidean distance metric, which is usually insufficient in forming the clusters. Instead in FCM, weighted distance metric utilizing pixel co-ordinates, RGB pixel color and/or intensity and image texture is commonly used. As the datasets scale increases rapidly it is difficult to use K-means and FCM to deal with massive data.
