A novel concatenated coding system for both narrowband and broadband power line communications (NB-PLC and BB-PLC) is proposed. The order of the inner and the outer codes switches from the G3-PLC standard and the interleaver is eliminated. The Error-and-erasure decoder (EED) is selected as the Reed-Solomon inner code is because the impulsive noises clearly mark the erasure positions with a thre...

This paper presents the complete description of a non-iterative algorithm for the distributed component based simulation of the dynamics of multibodies. The simulation of well-partitioned systems has complexity O(N), where N is the total number of bodies. The algorithm was implemented in the Virtual Systems Developer (VSD) software. In contrast to other tools, this one maintains the object-orie...

Considering the high consumption of the air compressors, a control system of screw compressor is designed and implemented to deal with energy saving and localization of mentioned compressor. In this paper the variable speed drive (VSD) control algorithm based on proportional-integral-derivative (PID) controller is optimized to decrease power consumption and more stable motor speed and outlet pr...

Infection is the major cause of neonatal deaths. Home born newborns in rural Bangladeshi communities are exposed to environmental factors increasing their vulnerability to a number of disease agents that may compromise their health. The current analysis was conducted to assess the association of very severe disease (VSD) in newborns in rural communities with temperature, rainfall, and humidity....

seems there is a semantic confusion in the definition of perimembranous VSD coming from the vague definition given by many authors using the term subarterial or subaor-tic VSD to describe perimembranous VSD. When the aorta is far away, it seems that there is difficulty in distinguishing perimembranous VSD from inlet VSD. The definition of the membranous septum is independent from the aortic ann...

The M-mode echocardiographic findings of ventricular septal defect (VSD) are nonspecific. A specific pulsed Doppler echocardiographic (PDE) diagnosis of VSD can be made by following the turbulent VSD jet through the septum. To assess the sensitivity, specificity and limitations of PDE diagnosis of VSD, 105 children undergoing cardiac catheterization were examined by PDE. These children had a va...

OBJECTIVES To determine the correlation exists between ventricular septal defect (VSD) and ruptured sinus of Valsalva aneurysm (RSVA). Methods: Between September 2003 and April 2014, 80 RSVA patients underwent surgical repair. These patients were retrospectively divided into two groups: the VSD group (38 cases) and the non-VSD group (42 cases).  Results: Rupture points of SVA originated more fr...

Using real-time image processing we have demonstrated a low bit-rate free-space optical communication system at a range of more than 20km with an average optical transmission power of less than 2mW. The transmitter is an autonomous one cubic inch microprocessor-controlled sensor node with a laser diode output. The receiver is a standard CCD camera with a 1-inch aperture lens, and both hardware ...

In previous paper the authors successfully developed a vibration suppression device (VSD) that has variable moment of inertia using Magneto-Rheological (MR) fluid. The MR fluid is filled into flywheel. Ferrite particles are clustered when magnetic field applied to flywheel by electromagnets, series mass VSD will be switchable. this seismic tests during switching reinforcement learning focused i...
