This paper investigates the use of a new hybrid vector quantizer called switched multistage vector quantization (SWMSVQ) technique using hard and soft decision schemes, for coding of narrow band speech signals. This technique is a hybrid of switch vector quantization technique and multistage vector quantization technique. SWMSVQ quantizes the linear predictive coefficients (LPC) in terms of the...

Many low-mass X-ray binaries show both hard and soft spectral states. For several sources the transitions between these states have been observed, mostly from the soft to the hard state during a luminosity decrease. In a few cases also the transition from the hard to the soft state was observed, coincident with an increase of the luminosity. Surprisingly this luminosity was not the same as the ...

This paper presents a novel low-cost, highly efficient, reliable and compact motor drive topology for residential and commercial application. The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC ...

In neutron star and black hole X-ray binaries the transitions between the two spectral states, hard and soft, signals the change between accretion via a hot advection-dominated flow(ADAF) and disk accretion. In a few cases the hard/soft transition were observed during the rise to the nova outburst, mostly only the soft/hard transition during the luminosity decrease. Surprisingly the luminositie...

In this paper the simulation and design of a quantum-film electro-optic switch is considered. This photonic device, is made from a new organic dipolar material called MNA or 2-methyl-4 nitroaniline, which possesses a high merit in comparison with it's inorganic counterparts (e.g. LiNbO3, GaAs, InSb, Quartz, etc). Montecarlo method is used to simulate the photon-it-electron interaction in this m...

introduction patients with palliated congenital heart disease may present later in life for major, non-cardiac surgical procedures. although alternative surgical techniques are now available for the treatment of the transposition of the great arteries (tga), an atrial level baffle (mustard or senning procedure) was previously performed. long-term adverse effects of the atrial level switch inclu...

In recent years, the use of robots has been considered due to labor shortage. this situation, utilization soft robot grippers that can grasp various objects is expected in industrial world. The purpose study develop a robotic hand with an adhesion pad attached jamming gripper enable grasping flat and complex shaped objects. we have developed be switched between suction by switch control. This m...

The controllable manipulation of gallium-based liquid metal (LM) droplet presents a promising option toward the goal making fully soft machines, which features an autonomy via external administration apparatus. While most current endeavors mainly concentrate on LM-assisted actuations for robots, it is noteworthy that peculiar behavior and LM circuits thus enabled can be adopted as intelligent e...

Single-switch quasi-resonant DC inverters are preferred in low-power induction-heating applications for their cheapness. However, they pose difficulties enforcing soft-switching and show limited controllability. A good design of these converters must proceed parallel with the characterization load operating conditions. The control switching frequency has a critical relationship to non-linear be...
