We present angle-uniform parallel coordinates, a data-independent technique that deforms the image plane of coordinates so angles linear relationships between two variables are linearly mapped along horizontal axis plot. Despite being common method for visualizing multidimensional data, ineffective revealing positive correlations since associated points such structures may be located at infinit...

Laser forming is a modern process which is mainly used for forming metals. Different Lasers are used in this regard that includes Nd: YAG and CO2. In this study, forming bi-layer sheets of Aluminum/Ceramic by Laser was investigated. Furthermore, effect of Uniform and Gaussian heat flux distribution in different power, velocity, and beam diameters on bending angle was studied. FEM simulation ind...

In a recent article (Katsav and Heyman, 2020), we derived an approximate tip-diffraction coefficient for circular wide-angle cones. the present work, derive uniform solution field in geometrical optics (GO) transition zones. The has form of Weber parabolic cylinder function order −3/2, but far from zones, it reduces to separate reflection tip diffraction contributions. derivation utilizes spect...

We consider the convergence problem of autonomous mobile robots with inaccurate sensors, which may return the erroneous location of other robots. In this paper, we newly introduce a uniform error model, which is a restricted variant of the original observation-error model proposed by Cohen and Peleg [4]. The degree of an observation error is characterized by distance errors and angle errors. Wh...

spect detects γ-rays from administered radiopharmaceutical within the patient body. γ-rays pass through different tissues before reaching detectors and are attenuated. attenuation can cause artifacts; therefore different methods are used to minimize attenuation effects. in our study efficacy of chang method was evaluated for attenuation purpose, using a custom made heart phantom. due to differe...

In the present investigation, two dimensional elastoplastic finite element analysis was conducted to assess the deformation characteristics of Al 1100 alloy during continuous confined strip shearing (C2S2) process. The results of simulations showed that the plastic strain distribution across the deformed sample is non-uniform irrespective of the amount of friction and C2S2 die angle. The most u...
