A symmetrized split-step Fourier (SSSF) simulation model with global simulation accuracy control is extended to vector optical fiber multi-span propagation cases, which are applicable to the waveform level simulation of polarization multiplexed coherent optical communication systems. Using local error bound obtained from a scalar simulation package, the prescribed global simulation accuracy can...

the present study was initiated to derive an indirect method for estimating body fat mass (bfm) and to evaluate the correlation between indirect anthropometric techniques for this estimation and to examine the relation of these parameters and of iq to age of menarche. a total of 578 adolescent girls of ten junior high schools in five educational districts of mashhad, participated in a cross sec...

In this work we consider the problem of continuously monitoring a collection of data sets produced by sensors placed on moving or static targets. We propose a modification of the static sensor field model (SSSF) [2] to model computation in a dynamic network of tiny artifacts. We consider mobility coming from both the communication devices and the data. The mobility of devices is simulated by a ...

In this work we present some implementations of a Static Synchronus Sensor Field (SSSF) [2], a static and synchronus model for sensor networks in which a finite set of sensing devices are geographically distributed and can communicate among them. We used for implementations the NiMo (Nets in Motion) [1] programming language, a graphic-functional-dataflow language that allows a step by step visu...

Multimodal medical image fusion is a fundamental, but challenging, problem in the fields of brain science research and disease diagnosis, as it challenging for sparse representation (SR)-based to characterize activity levels with single measurement not lose effective information. In this study, Kronecker-criterion-based SR framework was applied patch-based level, integrating salient features mu...

BACKGROUND The syndrome of the sinking skin flap (SSSF) with delayed sensorimotor deficits after craniectomy is not well known and often neglected. Among various postulated causes, there is evidence that disturbed brain perfusion may be related to the observed symptoms, and that cranioplasty reliably alleviates these symptoms. We report a case of sinking skin flap syndrome (SSFS) with recovery ...

Here we survey various computational models for Wireless Sensor Networks (WSNs). The population protocol model (PP) considers networks of tiny mobile finite-state artifacts that can sense the environment and communicate in pairs to perform a computation. The mediated population protocol model (MPP) enhances the previous model by allowing the communication links to have a constant size buffer, p...

UNLABELLED Weight and height measurements are important data for the evaluation of nutritional status but some situations prevent the execution of these measurements in the standard manner, using special equipment or an estimate by predictive equations. Predictive equations of height and weight requiring only a metric tape as an instrument have been recently developed. OBJECTIVE To validate t...

Our aim was to verify the tracking of body adiposity indicators from childhood to adolescence and analyze the mediation effects of BMI on the stability of body adiposity. Our sample was composed by 375 children (197 boys). The children were followed-up over 3 years. Body mass and stature were measured as anthropometric indicators. Body adiposity was estimated through the subcutaneous skinfold m...
