Inserting remote control valves in a water distribution system allows the implementation of the “divide and conquer” paradigm that consists in dividing a large network into smaller subsystems, also called water network partitioning (WNP), for applying water balance, pressure control and water quality protection. Some heuristic procedures, based on different techniques (graph theory, clustering,...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
We propose two new models for view-independent face recognition, which lies under the category of multiview approaches. We use the so-called “mixture of experts” (MOE) in which, the problem space is divided into several subspaces for the experts, and then the outputs of experts are combined by a gating network to form the final output. Basically, our focus is on the way that the face space is p...
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...
نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
The purpose of this study was to collect experimental data and develop a mathematical model describing the equilibrium phase distribution of a common organic chemical, trichloroethylene (TCE), among cyclodextrin (CD), water, and granular-activated carbon (GAC). Batch tests and a modified linear regression model were applied to assess the partitioning behavior in this multiphase (CD pseudophase–...
Partitioning and Dynamic Load Balancing for the Numerical Solution of Partial Differential Equations
In parallel simulations, partitioning and load-balancing algorithms compute the distribution of application data and work to processors. The effectiveness of this distribution greatly influences the performance of a parallel simulation. Decompositions that balance processor loads while keeping the application’s communication costs low are preferred. Although a wide variety of partitioning and l...
Introduction: Volatile organic compounds such as xylene, which are the main constituents of the oil and petrochemical industries, have serious impacts on health and can cause adverse effects on the environment. It is clear that release of these compounds into the environment should be controlled. The two-phases partitioning stirred tank bio-reactor is one of the newest methods for treating thes...
