A d-feedback-with-carry shift register (d-FCSR) is a finite state machine, similar to a linear feedback shift register, in which a small amount of memory and a delay (by d-clock cycles) is used in the feedback algorithm (see [4, 5]). The output sequences of these simple devices may be described using arithmetic in a ramified extension field of the rational numbers. In this paper we show how man...
Introduction: Many employees in different professions including nurses work with shifts. On the other hand, different and long shift work can endanger physical and mental health of nurses. This study, according to ergonomic standards, aimed to design a model for shift working in order to minimize the problems caused by shift work. Methods: In this study, all 35 nurses working in the emergen...
Background: During the course of disease, particularly of chronic diseases, changes in internal standards cause certain changes in the estimation of quality of life (QOL). These changes indicate the phenomenon of ‘response shift’. The present study aimed at assessing response shift in different scales of QOL in Iranian cancer patients. Methods: To assess response shift...
Background: Obesity is one of the most important health problems, so it is very important to identify its causes. Shift work is one of the factors that causes people to become obese. The aim of this study was to examine the relationship between shift work and obesity in taxi drivers. Methods: In this cross sectional study conducted in 2016, 120 male taxi drivers from Yazd were studied for demog...
Background and Aim: In recent decades, the issue of stress and its negative consequences such as violence in the workplace, increased accidents at work, Absenteeism and burnout, have deleterious effects on the efficiency and economy. The aim of this study was to determine the occupational stress of pelletizing industry workers and its determinants. Methods: This study was descriptive - analyti...
Background : According to the previous studies, 25 percent of the total workforce is faced with the shift working. Sleep disorders are the most common health complaint of the shift workers. This study was designed to examine the sleep status of workers in a printing factory. We aimed to investigate the association between prevalence of sleep disorders with shift working and other probable fac...
Introduction: The different factors that affect the camera uniformity of Single Photon Emission Computed Tomography (SPECT) technique have been analyzed including peak shift (%) and window width of energy. The effect of peak shift and window width on SPECT image uniformity has been investigated using a point source to perform intrinsic flood images. Methods:</stro...
The mean shift algorithm is one of the popular methods in visual tracking for non-rigid moving targets. Basically, it is able to locate repeatedly the central mode of a desirable target. Object representation in mean shift algorithm is based on its feature histogram within a non-oriented individual kernel mask. Truly, adjusting of the kernel scale is the most critical challenge in this method. ...
Introduction: Shift work as a social phenomenon is one of the effective factors on health workers operation which can have significant impacts on their health. Hence, the current study was conducted to determine the effect of shift working on health problems and the risk factors causing these disorders among nurses. Methods and Materials: This cross-sectional study was carried out in 120 nurse...
