1 . Average power Let us consider the transmission of energy from a source to a load, through a given surface as in Fig. 1. In the network of Fig. 1, the voltage waveform v(t) (not necessarily sinusoidal) is given by the source, and the current waveform is determined by the response of the load. In the more general case in which the source output impedance is significant, then v(t) and i(t) bot...

Given two sets A and B of n points each in R, we study the problem of computing a matching between A and B that minimizes the root mean square (rms) distance of matched pairs. We can compute an optimal matching in O(n2+δ) time, for any δ > 0, and an ε-approximation in time O((n/ε)3/2 log n). If the set B is allowed to move rigidly to minimize the rms distance, we can compute a rigid motion of B...

We present applications of variational – wavelet approach to different forms of nonlinear (rational) rms envelope equations. We have the representation for beam bunch oscillations as a multiresolution (multiscales) expansion in the base of compactly supported wavelet bases.

FMEA is a systematic process for indentifying potential design or process failure before they occur. The aim is to eliminate them or minimize the risk associated with them. The method is a procedure to analize failure modes and clasified them by severity. It is a systematic process for identifying potential failures before they occur with the intent to eliminate them or minimize the risk associ...

Do multinational Ž rms exhibit different patterns of labor demand from purely domestic Ž rms? Many standardmodels of trade and multinational companies suggest one such differencemay be labor-demand elasticities. For several reasons, multinationalsmay have more-elastic labor demands than do purely domestic Ž rms. In this paper we discuss the theory issues involved. We then present industry-level...

We investigate an economy in which ̄rms have di®erent risks to go bankrupt. We observe two things: ̄rst, workers in ̄rms with higher bankruptcy risk (bad ̄rms) always work less than workers in good ̄rms. Second, the CEOs of bad ̄rms may nonetheless receive larger wages.

Paratesticular rhabdomyosarcoma (RMS) occurs more frequently in children and is rare in adults. Embryonal RMS is the most common subtype of paratesticular RMS. Spindle cell is a rare variant of embryonal RMS and is associated with a favorable prognosis in children. Data in adults is lacking. We present a case of paratesticular RMS in a 24-year-old man.

BACKGROUND There are limited data on the safety and efficacy of recruitment maneuvers (RMs) in acute lung injury (ALI) patients. OBJECTIVE To evaluate the frequency, timing, and risk factors for complications from RMs in adult ALI patients. METHODS Secondary analysis of data from a randomized controlled trial of a lung open ventilation strategy that included sustained inflation RMs. RESU...

objective: for the assessment of primary arch form, different methods have been used including qualitative classifications, inter-canine and inter-molar widths and quantitative and numerical methods using mathematical models. the purpose of this study was to compare the validity and reliability of cast analyzer x iranian software with those of curve expert professional version 1.1 for arch form...
