Products: | R&S  SMW200A | R&S  FSW The R&S  SMW200A together with the R&S  FSW is a state of the art testing solution that significantly reduces the required hardware for testing power amplifiers with envelope tracking and/or digital pre-distortion. This application note introduces the test solution in detail and presents corresponding measurement examples.

BACKGROUND Men who have sex with men (MSM) and female sex workers (FSW) are consistently shown to have a higher burden of HIV compared with other adults in Senegal. This study, HIV Prevention 2.0, evaluates the impact of the 3-tiered integrated stigma mitigation interventions (ISMIs) approach to optimizing HIV service delivery for key populations in Senegal. METHODS Baseline assessment includ...

The technically pure copper is being replaced by aluminium as conductive material in electrical transformers for power systems. This evolution brings new manufacturing challenges. One major difficulty is the limited weld ability and non-acceptable residual deformations of the aluminium, when welded by fusion arc welding processes. The Friction Stir Welding (FSW) was selected for evaluation cons...

OBJECTIVES To explore the effect of different patterns of condom use by clients and female sex workers (FSW) on HIV transmission in Mexico. METHODS Data from 2401 face-to-face interviews among FSW from Morelos and Michoacán in Mexico were used to build and parameterise a deterministic model of HIV transmission between FSW, their stable partners and clients. RESULTS For the observed patterns...

The objective of the current work is to show potential friction stir welding (FSW) and its variants join fibre-reinforced thermoplastic polymer (FRTP) composites. To accomplish that, FSW technique two other important variants, spot (FSSW) refill (RFSSW), are presented explained in a brief but complete way. Since joining FRTP composites by FSSW has not yet been demonstrated, literature review wi...

Underwater friction stir welding (UWFSW) is an advancement of conventional welding, which performed in air. The need for underwater calls more information to be explored the different materials. aim this research investigate UWFSW 2 mm titanium sheet joints their tensile and microstructural properties compare them with results (FSW) Also, nondestructive tests, such as radiography dye penetrant ...

Friction stir welding (FSW) is a solution to overcome the problems of AA 6061 welding. When initial temperature T0 material increased during FSW process while parameters are kept constant then parameter value can be lowered. was varied by Troom temperature, 50 0C, 75 100 0C and 125 0C. The weld joint design form square butt joint. By using this approach higher T0, with being constant, produce p...

INTRODUCTION Estimating the number of key populations at risk of HIV is essential for planning, monitoring, and evaluating prevention, care, and treatment programmes. We conducted this study to estimate the number of female sex workers (FSW) in major cities of Iran. METHODS We used three population size estimation methods (i.e., wisdom of the crowds, multiplier method, and network scale-up) t...

OBJECTIVES To estimate the average social network size in the general population and the size of HIV key affected populations (KAPs) in Chongqing municipality using the network scale-up method (NSUM). METHODS A general population survey was conducted in 2011 through a multistage random sampling method. Participants aged between 18 and 60 years were recruited. The average social network size (...
