This pqm pments a rasterbased algorithm for reconstruction of 3-D terrain data from contour information appearing on the conventional 2-D map The height of an interior point between two neighboring contam is defined by a linear interpolation formula wt.lose variables are the height of those contours arid distance from the point to the contours. The distance from an interior mint to the contour ...

In this paper we consider a class of distributed parameter systems governed by the heat equation on bounded domains in Rn. We consider two types of boundary inputs (actuators) and two types of boundary outputs (sensors). Allowing for any possible pairing of these, we consider a total of four possible arrangements of our system. The first type of input (control) is through the Neumann boundary c...

We study the problem of recovery the source a.t;x/F.x/ in the wave equation in anisotropic medium with a known so that a.0;x/ 6D 0 with a single measurement. We use Carleman estimates combined with geometric arguments and give sharp conditions for uniqueness. We also study the non-linear problem of recovery the sound speed in the equation utt c .x/u D 0with one measurement. We give sharp condi...

Given a polygon and a visibility range, the Myopic Watchman Problem with Discrete Vision (MWPDV) asks for a closed path P and a set of scan points S , such that (i) every point of the polygon is within visibility range of a scan point; and (ii) path length plus weighted sum of scan number along the tour is minimized. Alternatively, the bicriteria problem (ii’) aims at minimizing both scan numbe...

Abstract Objectives To investigate the effect of scanned area on accuracy and scan time intraoral scans an anterior implant. Materials methods Three operators experienced in scanning (at least 2-year experience) performed partial complete-arch (n = 10) a dentate resin model with implant at left central incisor site by using scanner (Trios3; 3Shape, Copenhagen, Denmark). Each partial- or was sup...

Collaborative beamforming (CB) and cooperative transmission (CT) have recently emerged as communication techniques that can make effective use of collaborative/cooperative nodes to create a virtual multiple-input/multiple-output (MIMO) system. Extending the lifetime of networks composed of batteryoperated nodes is a key issue in the design and operation of wireless sensor networks. This paper c...

Ambiguity in the solution of inverse problems arises when data are insufficient to define a unique solution (i.e., the problem is ill-posed). Data fusion has the potential to reduce this ambiguity by using other sensory data that complement the original data. This paper examines the application of data fusion to limited-angle computed tomography (CT) to resolve ambiguity. While CT in its conven...

Background and Aims: Biomolecules' optical and nonlinear optical properties are widely used for different medical diagnoses and applications in biophotonic devices. These properties are essential in studying biological processes in living tissues. Aside from biomolecules' linear optical characteristics, their nonlinear optical characteristics have lately been considered. Materials and Methods:...
