assessment of the park- ang damage index for performance levels of rc moment resisting frames
چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
15 صفحه اولA Historical Analysis of the Co-evolution of Gasoline Octane Number and Spark-Ignition Engines
In this work, the authors reviewed engine, vehicle, and fuel data since 1925 to examine the historical and recent coupling of compression ratio and fuel antiknock properties (i.e., octane number) in the U.S. light-duty vehicle market. The analysis identified historical time frames and trends and illustrated how three factors – consumer preferences, technical capabilities, and regulatory legisla...
متن کاملIs pain assessment feasible as a performance indicator for Dutch nursing homes? A cross-sectional approach.
Quality of care gains transparency with the help of performance indicators. For Dutch nursing homes, the current set of performance indicators does not include pain. To determine the feasibility of pain assessment as performance indicator, information about pain prevalence and analgesic prescription in one nursing home was collected. Within the time span of 3 days, pain intensity was measured i...
متن کاملLow-Temperature Combustion of High Octane Fuels in a Gasoline Compression Ignition Engine
Gasoline compression ignition (GCI) has been shown as one of the advanced combustion concepts that could potentially provide a pathway to achieve cleaner and more efficient combustion engines. Fuel and air in GCI are not fully premixed compared to homogeneous charge compression ignition (HCCI), which is a completely kinetic-controlled combustion system. Therefore, the combustion phasing can be ...
متن کاملGasoline Prices and Motor Vehicle Fatalities
Fatal motor vehicle crashes per capita remained relatively stable over the 1990s, in spite of new traffic safety laws and vehicle innovations. One explanation for this stability is that the price of gasoline declined, which resulted in more vehicle miles traveled and potentially more fatalities. By using 1983-2000 monthly gasoline price and fatality panel data and fixed effects specifications, ...
