This paper presents a theoretical approach to optimal control problems (OCPs) governed by a class of control systems with discontinuous right-hand sides. A possible application of the framework developed in this paper is constituted by the conventional sliding mode dynamic processes. The general theory of constrained OCPs is used as an analytic background for designing numerically tractable sch...
A survey was undertaken for screening the organochlorine pesticides (OCPs) residue in eggs and meat samples collected from Namakkal (Tamil Nadu). Samples were analyzed by thin layer chromatography and con rmed by gas chromatography-mass spectrometry. Total endosulfan in egg (33.33 %) and broiler meat (50%) were exceeded the MRL of Codex alimentarius. Desi chicken adipose tissue had high incide...
سموم کشاورزی که به همراه آب های جاری وارد استخر های پرورش ماهی می شوند، میتوانند اثرات زیانباری بر عملکرد و سلامتی ماهی کپور داشته باشند. هدف از این تحقیق بررسی تاثیر سموم ارگانو کلره آندوسولفان و ارگانو فسفره دیازینون بر پارامتر های خونی و سرمی ماهی کپور معمولی بود. برای این منظور ماهی کپور معمولی در معرض غلظت های مختلف از سموم آندوسولفان و دیازینون قرار گرفت تا میزان lc50 در 96 ساعت تعیین شود...
Organic pesticides were developed during and after World War II to displaced inorganic and metal organic substances such as sulfur, arsenic, sodium fluoride and boric acid, which used by society for thousands of year. Some of these pesticides were OCPs which are organic compounds that contain chlorine. These OCPs were preferred because of their effective against the target pests even if only sm...
Adolescents are frequently prescribed hormonal contraceptive agents for both contraceptive and noncontraceptive purposes. Over half of all sexually experienced females aged 15 to 19 have used some form of hormonal contraception: 56% oral contraceptive pills (OCPs), 20% injectable, 14% emergency, 10% patch, and 5% ring. Given that 50% of adolescent girls have been sexually active before age 18, ...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
Object-based convolutional neural networks (OCNNs) have achieved great performance in the field of land-cover and land-use classification. Studies suggested that generation object positions (OCPs) largely determines OCNNs. Optimized distribution OCPs facilitates identification segmented objects with irregular shapes. In this study, we propose a morphology-based binary tree sampling (BTS) method...
The Network Enabled Optimization Server (NEOS) for solving tough optimal control problems (OCPs) is introduced. Though NEOS is generally used to solve static optimization problems, in solving dynamic optimizations (OCPs) in a general form, we show that the NEOS Server has some advantages over the existing dedicated optimal control software packages. After a step by step introduction of how to s...
This study evaluated the concentrations of organochlorine pesticides (OCPs) in inlet and outlet treatment plant Ahvaz city. For this purpose, six OCPs, including chlordane, dieldrin, dichlorodiphenyltrichloroethane, heptachlor, lindane, endrin were measured at three different sites during, 12 months. A gas chromatograph-mass spectrometer (GC-MS) device was applied for analysis determination tar...
Organic pollutants (PAHs, PCBs, and organochlorine pesticides (OCPs) from sediments Asian green mussels (Perna viridis) in Jakarta Bay were studied using GC-MS/MS. The PAHs concentration the ranged 186.64 to 915.71 µg.kg−1 per sediment dry weight (dw), while PCBs OCPs 3 117 17.99 dw, respectively. For P. viridis, 16 types of 591 997 dw mussels, varied 5 6 mussel. selected ratios, including Ant/...
