The concept of the city's landscape is connected with the objectivity and subjectivity of that city. Therefore, in order to manage this concept at night, in addition to functional-physical manifestations of the city, we should focus on the perceptual issues of citizens, which may have roots in their ancient identity, religion and customs. By accepting this hypothesis, a suitable model for night...
Poverty is a multi-dimensional problem and various researchers, based on their field, have investigated different aspects of poverty. Moreover, poverty, as a global problem, could be an interesting subject for both developed and developing countries. In recent decades, both international org...
This paper proposed a rapid level sets method based on HIS color space for the color image segmentation. First, we adopt the method of rapid level sets based on CV mode to improve the segmentation speed. Second, the segmentation of color image can be made with the introduction of the concept of color difference under HIS color mode. In this case, the segmentation can be made exactly even the gr...
از دو نمونه گل گلایل برنگهای قرمز و زرد که علائمی از قبیل بد شکلی و شکستگی رنگ گل color breaking و کوچک ماندن گلها stunting of florets از خود نشان میدادند دو ویروس مختلف جداشده و مورد بررسی قرار گرفتند. کرمهای این گیاهان را از noweta gradens در ایالت مینسوتای آمریکا آورده و در ایستگاه زراعی باجگاه کشت نموده بودند. براساس نوع میزبانها و علائم ایجاد شده در گیاهان خانواده های اسفناجیان (chenopodia...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
بررسی فرایند الکتروفنتون به منظور تصفیه ی پساب شرکت پتروشیمی شازند و بهینه سازی عوامل موثر بر فرایند
هدف از این تحقیق بررسی کارایی فرایند الکتروفنتون و بهینه سازی پارامترهای موثر بر فرایند به کمک طراحی آماری به منظور تصفیه پساب شرکت پتروشیمی شازند میباشد.در این تحقیق تاثیر پارامترهای : زمان واکنش ، چگالی جریان، ph پساب ، نسبت (?ml h?_2 o_2)/( lit pw) و نسبت مولی (mol h_2 o_2)/(mol fe^(2+) ) بر حذف cod و color از پساب پتروشیمی تحت فرایند الکتروفنتون( با الکترود های آهن و آلومینیوم به طور جداگان...
We propose a color-tunable light emitting diode (LED) consisting of a blue LED as the light source and quantum dot (QD) suspension as the color-conversion medium. The LED color temperature can be controlled by varying the liquid volume of each QD suspension with different photoluminescence colors. We simulate and optimize the light efficiency and color quality of the color-tunable LED and also ...
This paper presents our work on the retrieval of art documents for color artistry concepts. First we show that the query-byexample paradigm popularly used in content-based retrieval can support only limited queryability. The paper then proposes a concept-based retrieval engine based on the generative grammar of elecepts methodology. In the latter, the language by which color artistry concepts a...
Low light applications such as security and surveillance often require object identification and target discrimination which are made much easier with color imaging. However, most low light sensors tend to be monochrome since color filters used in Color imaging reduce light sensitivity. We present a two layer pixel concept for maximizing low light sensitivity which is capable of producing color...
