In this paper, a synchronization problem of a three-dimensional (3-D) Coullete chaotic system using the activeand adaptive-based synchronization control techniques is addressed. Based on the Routh-Hurwitz criterion and using the active control algorithm, a single control function is considered and a computational study is performed to identify the correct balance between the converging rates of...

This paper presents ongoing work on an advanced flexible circuit interconnect substrate featuring a 24 x 24 (576 element) pad grid array pattern at 300 micron pitch. This eight metal layer circuit is being developed as a highdensity, pixel-level interconnection substrate for a two-dimensional (2D) ultrasound imaging transducer MEMS device. The flexible circuit substrate is constructed using lam...

After a brief survey of iterative algorithms for general stochastic games, we concentrate on finite-step algorithms for two special classes of stochastic games. They are Single-Controller Stochastic Games and Perfect Information Stochastic Games. In the case of single-controller games, the transition probabilities depend on the actions of the same player in all states. In perfect information st...

BACKGROUND Heterosexual human immunodeficiency virus (HIV) transmission implies the crossing of the vaginal mucosa by virions present in the semen, potentially using Langerhans cells as transporters. The recruitment of these cells in the mucosa is mediated by the chemokine macrophage inflammatory protein 3alpha (CCL20). The aim of this study was to evaluate the capacity of the semen to induce L...

The effects of locking screw position (long column fixation--long distance between the nearest screws to the fracture--and short column fixation--short distance between the nearest screws to the fracture) and fracture gap size (1-mm and 8-mm transverse fracture gap) on stiffness and fatigue of fractured femur fixed with a locking compression plate (LCP) were biomechanically evaluated. The stiff...

Liquid crystalline polymers (LCPs) are complex systems that include features of both orientationally ordered mesophases and amorphous polymers. Frequently, the isotropic amorphous state cannot be studied due to the rapid mesophase formation. Here, a new main chain LCP, poly(triethyleneglycol methyl p,p'-bibenzoate), PTEMeB, has been synthesized. It shows a rather slow mesophase formation making...

In this paper, a microwave polarizer based on frequency selective surface (FSS) loaded with complementary split ring resonator (CSRR) for non-planar and conformal application is presented. The frequency-selective fabricated liquid crystal polymer substrates (LCPs) material <tex-math notati...

Permanent pacemaker implantation is not uncommon following valve surgery, but transvalvular, transvenous leads have the potential to negatively impact tricuspid function. Leadless cardiac pacemakers (LCP) are an attractive alternative for management of bradyarrhythmias occurring post-valve surgery. We sought assess safety and long-term efficacy LCPs during under direct visualization, in patient...

Although oil exploration and production has been going on in Cameroon, one of the greatest challenges how Cameroon can maximise potential benefits from to avoid under-development path that hits other producing countries. This challenge sprout as a result lack specialised skills development her industry. Thus, promotion LCPs industry is seen an ideal means enhance technology transfer sector. It ...

1 I n t r o d u c t i o n Liquid crystals of variety of molecular configurations may form the nematic phase, in which an orientational order, but no translational order, exists [1, 2]. These include the two drastically different configurations: rodlike and discotic liquid crystals. Most of the hydrodynan~ical theories formulated for liquid crystal materials are based on the rodlike molecules, w...
