اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...

Rating Tornado Damage: an Exercise in Subjectivity

Tornado ratings from the 1950s into the early 1970s were based almost entirely upon remote, post-event review of media articles and photographs (Schaefer and Edwards 1998). Starting in the middle 1970s, local National Weather Service (NWS) offices have assigned F-scale ratings to most tornadoes based on a blend of f irst-hand surveys by their meteorologists and anecdotal evidence from news medi...

Diagnosis of Conditional Maximum Tornado Damage Probabilities

Considerable effort in recent decades has focused on near-storm environment interrogation via model-based planar fields (e.g., Stensrud et al. 1997) and model-based proximity soundings in order to discriminate between nontornadic and significant (> F2) tornado environments for supercells (e.g., Thompson et al. 2003, hereafter T03; Thompson et al. 2007). This emphasis in severe environment discr...

Seismic Mitigation of Building Frames using Magnetorheological Damper (TECHNICAL NOTE)

The present study focusses on the damping force control of shear mode magnetorheological (MR) damper for seismic mitigations. Therefore, the semi-active MR damper which can control the vibration is analyzed both experimentally and numerically. Carbonyl iron is used as the magnetic particle and Castrol Magnetec oil as carrier fluid throughout the study. MR damper is designed and fabricated, and ...
