In estimating whether they are likely to improve on a performance task, people lean on a performance heuristic. That is, people rely on their previous performance success as a positive cue when estimating their prospects for performance improvement. Participants whose initial performance was better--either at a darts game (Study 1) or an anagram task (Study 2)-bet more money (Study 1) or estima...
This study is investigated the optimum parameters for a tuned mass damper (TMD) under the seismic excitation. Shuffled complex evolution (SCE) is a meta-heuristic optimization method which is used to find the optimum damping and tuning frequency ratio for a TMD. The efficiency of the TMD is evaluated by decreasing the structural displacement dynamic magnification factor (DDMF) and acceleration ...
یکی از حوادث طبیعی که هر ساله موجب خسارات مالی و جانی فراوانی می شود، پدیده زمین لغزش است. مناطق شمال ایران به علت شرایط اقلیمی، موقعیت و پوشش زمین، ارتعاش، ارتفاعات زیاد، باران های شدید و فرسایش سریع در نتیجه جنگل زدایی و ساخت و ساز در معرض خطر بالایی از لغزش قرار دارند. تهیه نقشه حساسیت و خطر زمین لغزش را می توان به عنوان راهکاری مناسب جهت کاهش خسارتهای ناشی از وقوع زمین لغزشهای آینده دانست. ...
This article addresses a multi-stage flowshop scheduling problem with equal number of unrelated parallel machines. The objective is to minimize the makespan for a given set of jobs in the system. This problem class is NP-hard in the strong sense, so a hybrid heuristic method for sequencing and then allocating operations of jobs to machines is developed. A number of test problems are randomly ge...
This study aims to forecast Iran's electricity demand by using meta-heuristic algorithms, and based on economic and social indexes. To approach the goal, two strategies are considered. In the first strategy, genetic algorithm (GA), particle swarm optimization (PSO), and imperialist competitive algorithm (ICA) are used to determine equations of electricity demand based on economic and social ind...
adolescents and young adults and their problems is an issue whose importance is obvious to anyone because youth are the founders of our countrys future and requires proper planning to be on leisure. given the importance of leisure,this study to investigate needs assessment and planning how adolescents and young adults spend their leisure time in urban of case study of high school girls and boys...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
