In order to serve emergency calls, figuring out the types of emergency is one of the most important tasks. The reaction for the call is dependent on the type of the emergency. However, serving emergency calls is based on not the evaluation but the interaction. The emergency type should be decided with insufficient information and the decided type leads to the next information. In this paper, we propose...
Given a quasi-triangulation of a molecule, searching the simplexes of a particular bounding state for the spherical probe of a given radius occurs frequently. While such simplexes can be found by linearly scanning all simplexes in the quasi-triangulation, it is desirable to do the search faster. This paper presents an algorithm for searching simplexes quickly using the kd-tree data structure. The...
In this paper, we propose a three-dimensional (3-D) channel estimation (CE) scheme to reduce the mean square error (MSE) in multi-antenna orthogonal frequency division multiplexing (OFDM) systems. Exploiting the channel correlation in the spatial domain as well as in the frequency and time domain, the proposed 3-D CE scheme can outperform conventional two-dimensional (2-D) CE schemes, by either reducing...
