This paper presents a novel method for remaining useful life prediction using the Elliptical Basis Function (EBF) network and a Markov chain. The EBF structure is trained by a modified Expectation-Maximization (EM) algorithm in order to take into account the missing covariate set. No explicit extrapolation is needed for internal covariates while a Markov chain is constructed to represent the ev...
Background: The airway surface liquid (ASL), which is a ï‚uid layer coating the interior epithelial surface of the bronchi and bronchiolesis, plays an important defensive role against foreign particles and chemicals entering lungs.Objective: Numerical investigation has been employed to solve two-layer model consisting of mucus layer as a viscoelastic fluid and periciliary liquid layer as a New...
BACKGROUND Durations of exclusive breastfeeding (EBF) and predominant breastfeeding (PBF) from two different assessments, among the same mother-infant population, were investigated to determine the degree to which the assessments yielded overlapping results. METHODS Thirty Ugandan mother-infant pairs were followed up weekly from birth to three months of age with weekly short-time feeding reca...
The transition from natural forest to plantations has increased dramatically in the past decades. Forest conversion will affect soil properties and thus ecosystem services. Based on indicators, we studied differences of services among three types Liuxihe National Park analyzed effects artificial results showed that carbon sequestration evergreen broadleaf (EBF) was stronger, organic density (36...
در کشور ما ایران، یکی از روشهای بسیار مناسب برای مقابله با نیروهای جانبی زلزله، استفاده از سیست مهاربندی با بادبندهای فلزی می باشد. در تعیین شکل و محل مناسب برای بادبندها، این نقط نظرات معمار است که اغلب حکمفرما می شود. حال این سوال پیش می آید که اگر قرار باشد مهندس محاسب، بهترین فرم و محل را برای بدبندها ارائه کند چه تصمیمی خواهد گرفت.در این پروژه، ابتدا رفتار کلیه سیستم های بادبدی، شامل بادبن...
Background: Exclusive breastfeeding (EBF) is recommended the first six months after birth as one of cost effective interventions in saving children's lives. Objective: To determine the prevalence of exclusive breastfeeding and describe the common foods introduced to infants before 6months. Design: A prospective cohort study. Setting: Poor community of Moshi urban, Kilimanjaro region, Tanzania. ...
OBJECTIVE To examine the effect of peer support on duration of exclusive breastfeeding (EBF) in low and middle-income countries (LMICs). DATA SOURCES Medline, EMBASE, and Cochrane Central Register for Controlled Trials were searched from inception to April 2012. METHODS Two authors independently searched, reviewed, and assessed the quality of randomized controlled trials utilizing peer supp...
The development of mature B lymphoid cells involves a highly orchestrated regulation of stage- and lineage-specific genes. In this study, we report an analysis of the human surrogate L chain VpreB promoter. The promoter has an overall homology of 56% to the mouse counterpart and displays a preB cell-restricted activity in transient transfections in cell lines. The promoter harbors three indepen...
Abstract Background Freezing injury, which is an important abiotic stress in horticultural crops, influences the growth and development production area of kiwifruit ( Actinidia Lind1). Among species, arguta has excellent cold resistance, but knowledge relevant to molecular mechanisms still limited. Understanding mechanism underlying resistance for breeding resistance. Results In our study, a po...
در این مقاله مدلی برای آنالیز صحیح تیر رابط در قابهای ebf ارائه شده است. در این مدل جان و بال تیر رابط i شکل به طور جداگانه مدل میشوند. ماتریس سختی المان جان تیر رابط شبیه المان غشائی است و از روش اجزاء محدود محاسبه شده و توسط روش گوس در 8 نقطه انتگرال گیری میشود. همچنین این المان در نقاط گوس قابلیت جاری شدن دارد که به این ترتیب میتوان جاری شدن جان تیر رابط را بررسی کرد . همچنین در المانهای تیر...
