1-type and biharmonic curves by using laplace operator in lorentzian 3-space arestudied and some theorems and characterizations are given for these curves.

background: major attention has been drawn to the prognostic value of plasma/serum neutrophil gelatinase-associated lipocalin (ngal) in detection of acute kidney injury (aki) in children, but still no consensus has been reached. accordingly, the present study aimed to assess the diagnostic value of this biomarker in detection of acute kidney injury in children through a systematic review and me...

soil water retention curve (swrc) is important in the studies of soil and water relationship, soil conservation, irrigation scheduling, drainage, solute transport, plant growth and crop water stress. the performance of 10 models (simons et al., libardy et al., campbell, farrell and larson, van genuchten, brooks and corey, driessen, exponential bruce-luxmore, power bruce-luxmore, and rogowski) w...

A data-driven approach to the performance analysis of wind turbines is presented. Turbine performance is captured with a power curve. The power curves are constructed using historical wind turbine data. Three power curve models are developed, one by the least squares method and the other by the maximum likelihood estimation method. The models are solved by an evolutionary strategy algorithm. Th...

Today's overall grasp and prediction of the trend changes in sports scores, led this study to carry out the discussion that the athletes’ obtaining reasonable suggestion is particularly important to fundamentally improve the comprehensive quality of track and field athletes performance. The Olympic Games is the big games, and the ‘stand or fall’ of achievements is the only measure of players pe...

This investigation explores the common assumption that music and motion are closely related by comparing the stopping of running and the termination of a piece of music. Video recordings were made of professional dancers’ stopping from running under different deceleration conditions, and instant values of body velocity, step frequency, and step length were estimated. In decelerations that were ...

The spectrometer SPI on INTEGRAL allows for the first time simultaneous imaging of diffuse and point-like emission in the hard X-ray and soft gamma-ray regime. To fully exploit the capabilities of the instrument, we implemented the MREM image deconvolution algorithm, initially developed for COMPTEL data analysis, to SPI data analysis. We present the performances of the algorithm by means of sim...
