Evolution of affordable assistive technologies like eye tracking help people with motor disabilities to access information on the Internet or work on computers. However, eye tracking environments need to be specially built for better usability and accessibility of the content and should not be on interface layouts that are conducive to conventional mouse or(More)
Geographic Information Retrieval (GIR) is a specialized branch of traditional Information Retrieval (IR), which deals with the information related to geographic locations. One of the main challenges of GIR is to quantify the spatial relevance of documents and generate a pertinent ranking of the results according to the spatial information needs of user.(More)
The user interfaces and input events are typically composed of mouse and keyboard interactions in generic applications. Eye-controlled applications need to revise these interactions to eye gestures, and hence design and optimization of interface elements becomes a substantial feature. In this work, we propose a novel eyeGUI framework, to support the(More)
Local search services provide information access about specific locations, facilities and geographic points of interest. However, in various information seeking situations users are not only interested in the specific geo entities but the composition of urban areas and geographic regions. Users need to specify, analyze and compare the geographic regions,(More)
A new method for sentence extraction on the basis of language model with relative entropy is presented in this paper. The proposed technique first builds a sentence language model and document cluster language model respectively for the sentence and the documents. The sentences are then ranked according to the relative entropies of the estimated document(More)
Increasing volumes of spatial data about urban areas are captured and made available via volunteered geographic information (VGI) sources, such as OpenStreetMap (OSM). Hence, new opportunities arise for regional exploration that can lead to improvements in the lives of citizens through spatial decision support. We believe that the VGI data of the urban(More)
Predicting calcium binding proteins and identifying calcium-binding sites is an important problem in the field of proteomics. Most of the currently used methods employ structural protein data to predict calcium-binding sites. Here we present a method developed to predict calcium-binding proteins and identify calcium-binding sites from protein sequence data(More)
Geographic information retrieval (GIR) has commonly been exploited for the search of specific points of interest using conventional text-based query methods. Such input methods restrict end users' search to predefined spatial boundaries. However in some scenarios, users' spatial information need do not only rely in specific places, but rather in the search(More)
Loads connected to a stiff source cannot be protected from voltage disturbances using a distribution static compensator (DSTATCOM). In this paper, a new control-algorithm-based multifunctional DSTATCOM is proposed to operate in voltage control mode under stiff source. This scheme provides fast voltage regulation at the load terminal during voltage(More)
