Graph coloring is used in wireless networks to optimize network resources: bandwidth and energy. Nodes access the medium according to their color. It is the responsibility of the coloring algorithm to ensure that interfering nodes do not have the same color. In this research report, we focus on wireless sensor networks with grid topologies. How does a coloring algorithm take advantage of the re...

Abstract Objective We developed a silver-containing hydroxyapatite (Ag-HA) coating to prevent periprosthetic joint infection (PJI). Methicillin-resistant Staphylococcus aureus (MRSA) is the main PJI-causing bacteria. Previously, we had reported combined effect of Ag-HA and vancomycin (VCM) on MRSA biofilm formation 24 h after inoculation. In this study, investigated time-dependent efficacy VCM ...

La violencia contra las mujeres en relaciones de pareja (VcM) es una problemática estructural y compleja cuyos impactos son inconmensurables. universidad no ajena a esta realidad entre su personal están que han sido agredidas por sus parejas, lo cual ha dejado huellas imborrables vida. El objetivo este estudio fue determinar la incidencia VcM vida el desempeño laboral trabajadoras Universidad M...

The paper considers a range of tasks related to the processing and analysis petrophysical data, which are effectively solved by method group accounting arguments (MGUA). MGUA is machine learning that an alternative regression neural network modeling. was tested when working with information from database crystalline sedimentary rocks Voronezh Crystal Massif (VCM). basis technology formation com...

HPRC (High-Performance Reconfigurable Computing) systems include multicore processors and reconfigurable devices acting as custom coprocessors. Due to economic constraints, the number of reconfigurable devices is usually smaller than the number of processor cores, thus preventing that a 1:1 mapping between cores and coprocessors could be achieved. This paper presents a solution to this problem,...

TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) was combusted in a well-controlled laboratoryscale incinerator at a temperature of 700 °C, and then dioxins (PCDDs, PCDFs and coplanar-PCBs) formed in the exhaust gases were analyzed by high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). TEPVC sample was prepared by the suspension polymerization of vinyl ...

This paper analyzes the parasitic effects in SAR ADCs. Successive approximation technique in ADC is well known logic, where in the presented design the linearity analysis of a Successive Approximation Registers (SAR) Analog-to-Digital Converter (ADC) with split DAC structure based on two switching methods: VCM -based switching, Switch to switchback process. The main motivation is to implement d...

Currently, HDD (Hard Disk Drive) with VCM actuator covers more than 80% of the HDD market. To enhance the capacity and ability of the system, a new class of servo controller is required to achieve both the robustness and performance of the entire system. This paper proposes a new technique for designing a robust controller for HDD with Voice Coil motor (VCM) actuator; the control design problem...

We present new results obtained from the modeling of a tulip-like variable curvature mirror (VCM) in case central force that reacts to its contour. From Nastran finite element analysis, we shows 3-D optimizations, using non-linear static flexural option, with an appropriate solution sequence, provide accurate VCM thickness distribution. This allows us take into account boundary conditions, incl...
