a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
wireless sensor networks (wsns) arebecoming increasingly popular, and very useful in militaryapplications and environmental monitoring. however,security is a major challenge for wsns because they areusually setup in unprotected environments. our goal in thisstudy is to simulate an intrusion detection system (ids)that monitors the wsn and report intrusions accurately andeffectively. we have thus...
it is well known that damaged structural members may alter the behaviour of the structures considerably. careful observation of these changes has often been viewed as a means to identify and assess the location and severity of damages in structures. among the responses of a structure, natural frequencies and natural modes are both relatively easy to obtain and independent from external excitati...
the human facial recognition is the base for all facial processing systems. in this work a basicmethod is presented for the reduction of detection time in fixed image with different color levels.the proposed method is the simplest approach in face spatial localization, since it doesn’trequire the dynamics of images and information of the color of skin in image background. inaddition, to do face...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
در سال های اخیر پیشرفت مربوط به فناوری اطلاعات، باعث تحول صنعت بانکداری در حوز? بانکداری الکترونیکی شده است. خصوصاً پیشرفت در فناوری بی سیم، و ارائ? بانکداری سیار، انعطاف پذیری زمانی و مکانی در استفاده از خدمات بانکداری را برای مشتریان فراهم آورده است. نگرانی های امنیتی مسأله ای است که توجه بسیاری را چه از فراهم کنندگان سرویس و چه کاربران را در حوز? بانکداری به خود معطوف کرده است. وجود یک دیوار ...
چکیده در دهه های اخیر، الگوریتم های شناسایی خرابی های سازه ای، یک موضوع مهم تحقیق بین المللی بوده است. گسترده ترین مطالب مطالعه شده، روش های غیر مخرب شناسایی صدمه بر پایه لرزش هستند (vibration-based damage detection methods). از جمله جدیدترین این روش ها، پردازش سیگنال پاسخ جابجایی و شتاب پل به وسیله نقلیه، با استفاده از تبدیل موجک و تبدیل هیلبرت هانگ به منظور تشخیص آسیب در آن بوده است، لیکن به...
