The basic problem of target motion analysis (TMA) is to estimate the trajectory of an object (Le. position and velocity for a rectilinear movement) from noise corrupted sensor data. The problem is quite easy for a rectilinear movement of the source, but numerous problem arise when it maneuvers. Our main goal is to apply hidden markov modelling to this, and to optimize the estimability of the so...

Introduction. This research addresses preschoolers' intuitive understanding of rectilinear

Given a set of disjoint groups of points in the plane, the rectilinear group Steiner tree problem is the problem of nding a shortest intercon-nection (under the rectilinear metric) which includes at least one point from each group. This is an important generalization of the well-known rectilinear Steiner tree problem which has direct applications in VLSI design, i.e., it is the fundamental prob...

A new algorithm called adaptive cluster growth (ACG) for circuit packing (or detailed placement) in any rectilinear region is described; it is an analogy to the growth of a low-stress crystal in a cavity of any given shape. The algorithm ACG is suitable for the packing of circuit modules, either standard-cell or macrocell, in a rectilinear region by the refinement of a result of global placemen...

We show that the problem whether a given finite metric space (X, d) can be embedded into the rectilinear space R m can be formulated in terms of m-colorability of a certain hypergraph associated with (X, d). This is used to close a gap in the proof of an assertion of Bandelt and Chepoi [2] on certain critical metric spaces for this embedding problem. We also consider the question of determining...

Widely linear (WL) receivers have been developed in the past for single antenna interference cancellation (SAIC) of one rectilinear (R) or quasi-rectilinear (QR) data-like multi-user (MUI) co-channel (CCI) particular. The SAIC technology has implemented global system mobile communications (GSM) handsets particular and further analyzed voice services over adaptive channels on slot (VAMOS) standa...

Although the widely linear least mean square error (WLMMSE) receiver has been an appealing option for multiple-input-multiple-output (MIMO) wireless systems, a statistical understanding on its pose-detection signal-to-interference-plus-noise ratio (SINR) in detail is still missing. To this end, we consider WLMMSE MIMO transmission system with rectilinear or quasi-rectilinear (QR) signals over u...

In this paper, we present an algorithm called FOARS for obstacle-avoiding rectilinear Steiner minimal tree (OARSMT) construction. FOARS applies a top-down approach which first partitions the set of pins into several subsets uncluttered by obstacles. Then an obstacle-avoiding Steiner tree is generated for each subset by an obstacle aware version of the rectilinear Steiner minimal tree (RSMT) alg...
