This paper addresses the problem of computing force-closure grasps with four non-coplanar contact points. The proposed approach in this work to determine force-closure grasp, is valid for sets of four faces with coplanar or non-coplanar normal, and is based on geometric operations. First, the sets of four object faces that due to their relative orientations and positions allow concurrent, flat-...

In this paper, different circuits of Quantum-dot Cellular Automata (QCA) are proposed for the so-called coplanar crossing. Coplanar crossing is one of the most interesting features of QCA because it allows for mono-layered interconnected circuits, whereas CMOS technology needs different levels of metalization. However, the characteristics of the coplanar crossing make it prone to malfunction du...

It is expected that an average protostar will undergo at least one impulsive interaction with a neighbouring protostar whilst a large fraction of its mass is still in a massive, extended disc. Such interactions must have a significant impact upon the evolution of the protostars and their discs. We have carried out a series of simulations of coplanar encounters between two stars, each possessing...

This paper presents a simulation of the spectroscopic performance of two large CZT coplanar detectors, 1.5 1.5 cm area and 1.0 cm thick, with coplanar anodes. A code, based on the GEANT libraries and classical Monte Carlo sampling, was developed to simulate experimental scenarios. This code adapts the GEANT capabilities for simulating complex detection systems for spectroscopic studies. Detecto...

The joint invariants of a pair of coplanar conics has been widely used in recent vision literature. In this paper, the algebraic invariant of a pair of non-coplanar conics in space is concerned. The algebraic invariant of a pair of non-coplanar conics is rst derived from the invariant algebra of a pair of quaternary quadratic forms by using the dual representation of space conics. Then, this al...

Aerobic degradation of PCBs though have been reported to be limited to less chlorinated biphenyls (PCBs), we report here of a marine mercury-resistant bacterium, Pseudomonas CH07 (NRRL B30604) which was capable of degrading a variety of highly chlorinated congeners of PCBs from the technical mixture Clophen A-50. Of the two most toxic coplanar PCBs present in Clophen A-50, one coplanar pentachl...

In this paper we proposed the estimation of the characteristic impedance, effect of dispersion, and the effective dielectric constant of Coplanar Waveguide (CPW) using conformal mapping theory and performances are analyzed. Numerically efficient and accurate formulae based on the conformal mapping method for the analysis of coplanar waveguide structures are presented. The analysis formulas for ...

of the matrix in a singular value decomposition [9]. A general algorithm which assumes that these feature points This paper presents a new method for the computation of the position and orientation of a camera with respect to a known are noncoplanar and fails to detect that this case is degenerobject, using four or more coplanar feature points. Starting with ate would probably produce inaccurat...
