A bi-objective mathematical model is developed to simultaneously consider the quay crane and yard truck scheduling problems at container terminals. Main real-world assumptions, such as quay cranes with non-crossing constraints, quay cranes’ safety margins and precedence constraints are considered in this model. This integrated approach leads to better efficiency and productivity at container te...
Background and aims: human errors are of the most important causes of accidents in medical professions which impose exorbitant costs to the societies. Therefore, the present research was carried out in order to identify and evaluate human errors, using SHERPA technique, among physicians and nurses in emergency unit of one of the hospitals in Semnan. Method: In this qualitative and cross-section...
Background: The Family Physician Program, one of the most important efforts of the Iran health system to establish a referral system, was developed and implemented in several provinces, but it faced challenges due to several reasons that prevented the program's progress. So This study was conducted to analyze the family physician program to identify the causes and challenges of the program fail...
Introduction: Human error plays a significant role in the occurrence of industrial accidents. Displacement and unloading operations are operations in which the occurrence of human error may lead to plenty of human and financial losses. The present study aimed to investigate the possibility of human error occurrence in overhead crane operators in a Steel Company in Hormozgan, Iran. Material & Me...
Assessment of limb function asymmetry is of interest to practitioners due to its role in return to play guidelines and reported links to injury. Dynamometry is one of the most commonly used methods of assessing muscle function, but the mode of contraction used is different to the stretch-shortening cycles experienced during real-life activities. The aim of this study was to compare measures of ...
This study was an attempt to investigate what metacognitive strategies are specifically employed by English learners when it comes to different speaking task types.60 students at advanced level (female) were randomly selected and given an OPT as a test of homogeneity. They were assigned to experimental and control groups. The MS questionnaire (Oxford, 1990) was also administered to see what MS ...
Introduction: Sexual dysfunctions are more common than previously thought. These types of disorders have many negative consequences. Sexual dysfunctions are closely linked to the social problems, such as crimes, mental illness and divorce. Lack of quality of life, anxiety, low self-esteem, selfishness, nervousness, tenderness of pain and discomfort, inability to concentrate on thinking and even...
Variations in hormonal levels between the follicular and the luteal phase of the female menstrual cycle are associated with variations in emotional and cognitive aspects of behavior. The functional neural correlates of these cycle-related variations have been explored in previous neuroimaging studies. We summarize the existing findings of functional magnetic resonance imaging (fMRI) studies to ...
A DMA controller that operates in the cycle-stealing mode is allowed to transfer data only when the CPU does not need the system bus. Thus, the execution time of a cycle-stealing DMA I/O task depends on the sequence of instructions executing concurrently with it. This paper describes a method for bounding the worst-case execution time (WCET) of a cycle-stealing DMA I/O task. We rst deene the ta...
