this study investigates the coordination of production scheduling and maintenance planning in theflow shop scheduling environment. the problem is considered in a bi-objective form, minimizing themakespan as the production scheduling criterion and minimizing the system unavailability as themaintenance planning criterion. the time interval between consecutive maintenance activities as well as the...
We introduce a new subclass of Allen’s interval algebra we call “ORD-Horn subclass,” which is a strict superset of the “pointisable subclass.” We prove that reasoning in the ORD-Horn subclass is a polynomial-time problem and show that the path-consistency method is sufficient for deciding satisfiability. Further, using an extensive machine-generated case analysis, we show that the ORD-Horn subc...
Interval logic has been introduced as a temporal logic that provides higher-level constructs and an intuitive graphical representation, making it easier in interval logic than in other temporal logics to specify and reason about concurrency in software and hardware designs. In this paper we present axiomatizations for two propositional interval logics and relate these logics to Until Temporal L...
Introduction Acupressure is one of the natural methods of labor induction but limited study has been done to evaluate its effectiveness. The aim of this study was to determine the effectiveness of acupressure for the initiation of labor. Methods: A randomized clinical trial was carried out at the Ganjavian hospital Dezful-Iran 2010. Eighty nulliparous women with uncomplicated pregnancy, single...
Introduction: Physiological hypertrophy following training manifests with cardiac mass changes. In addition, physical activities lead to Hand2 gene expression as an important gene in cardiac remodeling. The present study aimed to investigate the effects of endurance and high intensity interval Ttraining on Hand2 gene expression and cardiac changes. Method: For this intent, 24 male rats (age 3 ...
چکیده شیل های ارغوانی به عنوان یک عضو رسمی در قاعده سازند پابده در نقاط متعددی از زاگرس رخنمون دارند. به منظور بررسی چینه¬شناسی و محیط رسوبی شیل¬های ارغوانی در بخش شمالی حوضه زاگرس، 4 برش در استان ایلام در مناطق پاریاب، ملکشاهی، بیشه¬دراز و دره شهر به همراه برش الگوی سازند پابده واقع در تاقدیس گورپی در شرق استان خوزستان برداشت و مورد مطالعه قرار گرفت. در مجموع از این برش¬ها 507 اسلاید پالینول...
In recent years cardiac interbeat interval time series have been investigated by DFA and MF-DFA methods. In this paper instead of investigating cardiac interbeat interval time series, ECG signals are considered, it is shown that the normal and abnormal heart signals have different scaling relations.
