computation of the second order delay in rc-tree based circuits is important during the design process of modern vlsi systems with respect to having tree structure circuits. calculation of the second and higher order moments is possible in tree based networks. because of the closed form solution, computation speed and the ease of using the performance optimization in vlsi design methods such as...

The management of carpal dislocation after a late diagnosis is difficult. Open reduction is the usual treatment but collapse of the carpus may be hard to overcome without extensive dissection and consequent damage to the blood supply, ligaments and articular cartilage. A technique of distraction by an external fixator followed by semi-closed reduction is described and its successful use is repo...

A novel frequency domain technique for image blocking artifact reduction is presented in this paper. For each block, its DC and AC coefficients are recalculated for artifact reduction. To achieve this, a closed form representation of the optimal correction of the DCT coefficients is produced by minimizing a novel enhanced form of the Mean Squared Difference of Slope (MSDS), for every frequency ...

A method is described for the fabrication of a closed hollow bulb obturator prosthesis using a hard thermoforming splint material and heat-cured acrylic resin. The technique allowed the thickness of the thermoformed bulb to be optimized for weight reduction, while the autopolymerized seal area was covered in heat-cured acrylic resin, thus eliminating potential leakage and discoloration. This te...

We present a solution to the following reduction problem for asymptotic stability of closed sets in nonlinear systems. Given two closed, positively invariant subsets of the state space of a nonlinear system, Γ1 ⊂ Γ2, assuming that Γ1 is asymptotically stable relative to Γ2, find conditions under which Γ1 is asymptotically stable. We also investigate analogous reduction problems for stability an...

Posterior sternoclavicular joint dislocation (PSCJD) is quite a rare condition. Nearly half of the closed reduction attempts fail due to various reasons. In this paper, we present a 25-year-old male patient who was admitted to the emergency department in our hospital after having a motor-vehicle accident. It was decided to do PSCJD after physical and imaging studies. Following necessary prepara...
