در این مطالعه برج دانه سازی منطقه یک پتروشیمی شیراز با دو مدل شبیه سازی گردیده است و نتایج هر دو مدل با داده های صنعتی مقایسه شده است. در مدل اول (lumped model) از مقاومت حرارتی در داخل دانه صرف نظر شده است و توزیع دما در داخل دانه یکنواخت است . در مدل دوم (distributed model) برای نقاط داخلی دانه در جهت شعاع توزیع دما در نظر گرفته شده است . نتایج به دست آمده از هر دو مدل با داده های صنع...
The distributed lag model (DLM), used most prominently in air pollution studies, finds application wherever the effect of a covariate is delayed and distributed through time. We specify modified formulations of DLMs to provide computationally attractive, flexible varying-coefficient models that are applicable in any setting in which lagged covariates are regressed on a time-dependent response. ...
Background and Objectives: The Covid-19 epidemic began in Wuhan, China in the late 2019 and became a global epidemic in March 2020. In this regard, one of the most important indicators of the healthcare systems is the in-hospital mortality rate, which occurs with a time lag of one to two weeks after hospitalization. The aim of this study was to investigate the relative risk of Covid-19 mortalit...
Abstract Recursive systems of linear regressions is a consolidated methodology for mediation analysis, allowing to determine causal effects interest in closed form based on the regression coefficients. In dynamic perspective, distributed-lags can be added each order represent persisting over several periods. However, analysis case challenging, because depend time lag, and general procedure comp...
Understanding the potential links between floods and bacillary dysentery in China is important to develop appropriate intervention programs after floods. This study aimed to explore the distributed lag effects of floods on bacillary dysentery and to identify the vulnerable groups in Huaihua, China. Weekly number of bacillary dysentery cases from 2005-2011 were obtained during flood season. Floo...
