The Himalayan Sherpas, a human population of Tibetan descent, are highly adapted to life in the hypobaric hypoxia of high altitude. Mechanisms involving enhanced tissue oxygen delivery in comparison to Lowlander populations have been postulated to play a role in such adaptation. Whether differences in tissue oxygen utilization (i.e., metabolic adaptation) underpin this adaptation is not known, ...
Some results highlighting the status of a new version of a cluster fragmentation model for the Monte Carlo event generator Sherpa are presented. In its present version this model is capable of simulating e + e − annihilation events into light-quark and gluon jets. We compare results for different multiplicity and momentum distributions to available SLD and LEP data as well as to results obtaine...
زمینه و هدف : خطاهای انسانی نقش قابل ملاحظه ای را در بروز حوادث صنعتی دارند. یکی از عملیات های مهم مستعد خطای انسانی در معادن، عملیات آتش باری می باشد. به همین منظور هدف از این مطالعه شناسایی و ارزیابی ریسک خطاهای انسانی درعملیات آتش باری یک معدن سنگ آهن می باشد. روش بررسی : مطالعه ی حاضر، مطالعه مورد پژوهی از نوع پژوهش کیفی می باشد که به منظور شناسایی و ارزیابی خطای انسانی شغل آتش باری در یک...
زمینه و هدف: امروزه، انسان به عنوان طراح، برنامهریز و کاربر سیستمها، تجهیزات و ماشینآلات نقش بسیار مهمی در ایمنی آنها دارد. در یک سیستم پیچیده، رفتار کاربر، دارای پتانسیل بروز اشتباهاتی است که میتواند توانمندی سیستم را تحت تأثیر قرار دهد. در پژوهش حاضر خطاهای انسانی اپراتورهای پست های 400 کیلوولت شناسایی ، تحلیل و اثر بخشی راه کارهای کاهش آن بررسی گردیده است. روش بررسی: پس از شناسایی م...
I discuss the use of quantitative, qualitative, and collaborative methods to document and operationalize Indigenous ecological knowledge, using case studies from the Nepalese Himalaya and Great Basin. Both case studies applied results to natural and cultural resource management and interpretation for the public. These approaches attempt to reposition the interview subjects to serve as active co...
This paper presents the first experiment managed as part of the Sciences and Technologies for Safety in Transport (ST2) program, a French national research project. In this program, human physical reactions are studied in order to adapt primary and secondary safety systems to driver behavior. The objective of the present study was to examine how car drivers modify their posture just prior to a ...
This work proposes a new control approach for biped walking robots. Its purpose is to make human-like robots walk more smoothly and more efficiently with regard to energy. Thus, it is based on the decomposition of a step into two phases: a control phase which prepare a ballistic phase. As a first step towards more complex studies, the tools are simple and efficient: Lagrangian model, Newton’s i...
Background and aims: With a widespread regard to the human error issue and recognize the importance of human as an active processor of information The necessity for an effective framework to analyze different mental processes interact with the system to carry out job duties will be obvious. So the aim of this study was to analyze human errors by SHERPA and human information processing mod...
Introduction: Cranes are of the major causes of accidents in the construction industries. As human error mostly causes crane accidents, this study aims to investigate the human errors of tower crane operators in the construction projects using SHERPA and CREAM techniques. Material and Method: In this research, first, all of the tasks of the tower crane operator were identified and analyzed. Th...
Introduction: Human errors play a significant role in the occurrence of industrial accidents. This study aims to investigate the human errors in cabin roof crane operators of a metal industry using SHERPA and SPAR-H techniques. Material and Method: In this research, first, all of the tasks of the tower crane operator were identified and analyzed. Then, adopting SHERPA technique, p...
