Two field studies were conducted for one year using sorbent-impregnated polyurethane foam (SIP) disks for PCB and PBDE air sampling. SIP disks were introduced by Shoeib et al. (2008) as an alternative passive air sampling medium to the polyurethane foam (PUF) disk and have the advantage of a higher holding capacity for organic chemicals. The first study on SIP disks confirmed their application ...
Flow-level traffic measurement is important for network traffic accounting, traffic engineering, and network security. However, flow-level measurement in high speed networks poses great challenges due to the requirements of high packet processing speed and large memory size (high time/space complexity). To reduce these demanding requirements, sampling is usually used and samplers are deployed i...
The endogenous metabolites excreted by organisms into their surrounding environment, termed the exometabolome, are important for many processes including chemical communication. In fish biology, such metabolites are also known to be informative markers of physiological status. While metabolomics is increasingly used to investigate the endogenous biochemistry of organisms, no non-targeted studie...
Perfluorinated chemicals (PFCs) have been recognised as environmental pollutants that require monitoring. A modified polar organic chemical integrative sampler (POCIS) is able to quantify aqueous PFCs. However, with varying external water velocity, PFC sampling rates (Rs) may change, affecting accuracy of derived water concentrations. To facilitate field deployment of this sampler, two methods ...
This paper details how activity-based passive sampling methods (PSMs), which provide information on bioavailability in terms of freely dissolved contaminant concentrations (Cfree ), can be used to better inform risk management decision making at multiple points in the process of assessing and managing contaminated sediment sites. PSMs can increase certainty in site investigation and management,...
پیاده سازی تئوری تغییرشکل های یکنواخت در کنترل نیمه فعال سازه ها با استفاد ه از کنترل کننده های فازی
در این مطالعه هدف پیاده سازی یک سیستم کنترلی فازی بر مبنای تئوری تغییرشکل های یکنواخت برای کنترل نیمه فعال سازه های مجهز به میراگر با استفاده از الگوریتم بهینه یابی pso تحت بارهای لرزه ای است. در این پژوهش کارایی ایده ی یکنواخت کردن دریفت ها در کاهش پاسخ های لرزه ای سازه مورد بررسی قرار گرفته است. برای بررسی توانمندی استراتژی پیشنهادی برای سازه های مختلف و ارتعاشات لرزه ای متفاوت، شبیه سازی عدد...
High throughput applications using broadband impedance spectroscopy as method for label free detection are limited by measurement speed and the enormous amount of raw data. Although often ignored, the fastest method for determining the passive electrical properties is the processing of the answer after step excitation. Sampling with constant time interval is common but not feasible for real tim...
