In this paper, we propose architecture-independent parallel algorithms for solving Perceptual Grouping tasks on distributed memory machines. Given an n n image, using P processors, we show that these tasks can be performed in O(n 2 P) computation time and 20 p PT d +8(log P)T d +(40n p P +20P) d communication time, where T d is the communication startup time and d is the transmission rate. Our ...

[1] Aircraft observations from a recent campaign spanning 0–40N latitude are compared to coincident observations from satellite sensors on board the Aqua satellite of temperature, ozone, water vapor and cloud properties in the upper troposphere and lower stratosphere. Satellite observations compare well to aircraft data; temperature is generally within ±1.5 K and water vapor is within ±25% of a...

Polyvinyl ester green composites were synthesized with walnut shell powder (WSP) by in-situ polymerization technique. The green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. Sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...

Abstract The purpose of this study was to find the optimal parameters briquette making process (particle size and pressure), where optimization carried out based on values physical properties, namely density, elastic modulus ultimate tensile strength. method used in vary particle palm shell charcoal waste with sizes 40, 60, 80 100 mesh mixed chopped LDPE plastic a 0,5 x cm, starch adhesive wate...

—We present a framework for fully-simulatable h-out-of-n oblivious transfer (OT n h) with security against non-adaptive malicious adversaries. The framework costs six communication rounds and costs at most 40n public-key operations in computational overhead. Compared with the known protocols for fully-simulatable oblivious transfer that works in the plain mode (where there is no trusted common ...

Purpose: Purpose of this study to evaluate the effect implant position on prosthesis movement mandibular two implant-supported overdenture under simulating biting force. Materials and methodology: 30 experimental overdentures (N=30) were made for an edentulous test model, which included artificial mucosa. Based position, samples divided into three groups (n=10) (i.e., A E, B D,in between D). Fo...

Abstract In the present study, three coatings of Al 2 O 3 , –13%(TiO ) and –40%(TiO composite were deposited by thermally flame spray process. The comparative wear behaviour –TiO has been studied under high temperature levels up to 400 °C with help a tribometer at constant load 40N. Prior tribo-test, coating morphology elemental analysis examined field emission scanning electron microscope (FES...

Abstract Shell structures are recognized for their exceptional performance in withstanding compression forces, often utilized as roof components. However, Southeast Asia experiences significant annual losses due to floods, with inadequate structural mitigation despite high population concentrations seismic risk areas. Previous research explored thin shell elevated foundations mitigate flood eff...
