پیش‌بینی ذوب برف در حوزه‌های کوهستانی نقش مهمی در مدیریت منابع آبی ایفا می‌کند. لذا هیدرولوژی برف در این مناطق از اهمیت زیادی برخورداراست. در این پژوهش به دلیل نبود داده برف در حوزه بوجین از مدل SRM و HBV برای شبیه‌سازی ذوب برف استفاده گردید. ابتدا داده‌های دبی، بارش در دوره آماری 1387 تا 1389 تهیه و صحت سنجی گردید. به‌منظور پایش زمانی و مکانی سطح پوشش برف در مدل SRM، از داده‌های سنجندهMODIS در...

Systematic Review methodology (SRm) is an increasingly popular choice for literature reviews in the Social Sciences. Although, compared to traditional narrative reviews SRm appears timeconsuming and laborious, transparency and replicability of the methodology is argued to facilitate greater clarity of review. Nevertheless, researchers in Industrial, Work and Organizational (IWO) Psychology have...

Due to the highly nonlinearity of the flux-linkage characteristics of Switched Reluctance Motor drives (SRM), accurately modelling is cumbersome. In this paper, the offlinetrained and the online-trained Radial Basis function (RBF) neural network model are proposed for estimating the SRM flux-linkage under running conditions. To investigate the performance of the modelling schemes, the simulatio...

This paper proposes a semi-parametric software reliability model (SRM) based on a mixed gamma distribution, so-called the mixed gamma SRM. In addition, we develop the parameter estimation method for the mixed gamma SRM. Concretely, the estimation method is based on the Bayesian estimation and the parameter estimation algorithm is described by MCMC (Markov chain Monte Carlo) method with grouped ...

The wide application of switched reluctance motors (SRM) is limited by their higher vibration and acoustic noise. An accurate determination of resonant frequencies and mode shapes of the SRM stator is therefore essential for low acoustic noise design. Based on the structural finite element method and elasticity theory, 3D vibration modes and resonant frequencies of a 5 hp SRM with 8/6 poles are...

The certification of a new standard reference material for small-angle scattering [NIST Standard Reference Material (SRM) 3600: Absolute Intensity Calibration Standard for Small-Angle X-ray Scattering (SAXS)], based on glassy carbon, is presented. Creation of this SRM relies on the intrinsic primary calibration capabilities of the ultra-small-angle X-ray scattering technique. This article descr...

The purpose of this study was to assess the validity and reliability of the Wattbike cycle ergometer against the SRM Powermeter using a dynamic calibration rig (CALRIG) and trained and untrained human participants. Using the CALRIG power outputs of 50-1 250  W were assessed at cadences of 70 and 90  rev x min(-1). Validity and reliability data were also obtained from 3 repeated trials in both t...

The National Institute of Standards and Technology Standard Reference Material (SRM) 2460/2461 standard bullets and casings project will provide support to firearms examiners and to the National Integrated Ballistics Information Network (NIBIN) in the United States. The SRM bullet is designed as both a virtual and a physical bullet profile signature standard. The virtual standard is a set of si...

A unique, recently described rat alveolar macrophage cell line (NR8383) was used to study the interaction of the pulmonary immune system with a mucoid cystic fibrosis isolate of Pseudomonas aeruginosa (SRM-3), its nonmucoid revertant (SRM-3R), and a non-cystic fibrosis isolate (PAO-1). Strain SRM-3 was cultivated in a chemostat system to allow maintenance of an entirely mucoid population. The a...

Solar Radiation Management (SRM) has two characteristics that make it an attractive means for managing climate risk: it is quick and it is cheap. SRM cannot, however, exactly offset CO2-driven climate change, and its use introduces novel climate and environmental risks. We introduce SRM in a simple economic model of climate change that is designed to explore the interaction between uncertainty ...
