| The sensor network localization problem with distance information is to determine the positions of all sensors in a network, given the positions of some of the sensors and the distances between some pairs of sensors. A definition is given of what is ... Query Expansion is commonly used in Information Retrieval to overcome vocabulary mismatch issues, such as synonymy between the original query terms and a relevant document. In general, query expansion experiments exhibit mixed results. Overall TREC ... In a multimodal interface, a user can use multiple modalities, such as speech, gesture, and eye gaze etc., to communicate with a system. As a critical component in a multimodal interface, multimodal input fusion explores the ways to effectively interpret ... Poster presented for AusCTW 2009, Non-coherent fractional sampling UWB receiver Characterizations of the dynamic narrowband on-body to on-body, and on-body to off-body area channel A summary of statistical characterizations is presented of the dynamic narrowband on-body and on-body to off-body area channel at carrier frequencies near the 900 MHz and 2400 MHz Industrial, Scientific and Medical Bands. In consideration of an ... This paper finds the number of essential Fourier coefficients required to synthesise an arbitrary wave field composed of plane waves from all directions. We analyse the problem in rectangular coordinates for 1D, 2D and 3D regions, and our findings ... Abstract—This paper presents an efficient low-complexity clipping noise compensation scheme for PAR reduced orthogonal frequency division multiple access (OFDMA) systems. Conventional clipping noise compensation schemes proposed for OFDM systems are ... Walley's Imprecise Dirichlet Model (IDM) for categorical i.i.d. data extends the classical Dirichlet model to a set of priors. It overcomes several fundamental problems which other approaches to uncertainty suffer from. Yet, to be useful in practice, one ... |
