throughout life cycle of oil production wells, it is imperative to have production optimization and real response time to rapid changes of well conditions and more understanding of subsurface otherwise it is the matter of expenditure losing. smart well capabilities meet aforementioned issues. however there is a key concern in managers' mind that they have limited budget and several fields' docu...

block heights and capillary continuity between matrix blocks play paramount role in the sensitivity analysis and therefore the history matching of cumulative oil production and production rate of carbonated fractured reservoirs. in this study, the influence of these parameters upon cumulative production and recovery factor of an iranian fractured reservoir were studied by the usage of a simulat...

the energy efficiency, greenhouse gas (ghg) emissions, and carbon efficiency of paddy rice production were analysed in sari in the mazandaran province of iran during 2011–2012. data was collected through questionnaires and interviews with paddy producers. the results showed that the net energy gain was 27,932 mj ha-1 and energy efficiency was 1.83 during production. the results of the cobb-doug...

suspension system as one of the most important key elements of vehicle has always been considered by research centres and auto makers over the world and this issue is more important on sport cars which have special sensitive working conditions and even the smallest defect can strongly affect their performances. in this study, optimization of effective handling parameters of a sport car with thr...

The cumulative count of a conforming (CCC) control chart is used for high quality processes.The CCC − r chart is an improvement of the CCC chart that is based on the cumulative number of items inspected until observing r non-conforming ones. This paper aims to propose a new approach for manufacturer’s decision making according to the criteria among the available options. The o...

The paper deals with a technique of sensitivity calculation in linear hybrid networks containing elements with both lumped and distributed parameters when the multiconductor transmission lines (MTL) are considered as the distributed parts. The technique utilizes the modified nodal analysis (MNA) method to do overall description of the network enabling determining sensitivities with respect to b...

a carbon ionic liquid electrode (cile) modified with tio2-fe nanoparticles was constructed by incorporating tio2-fe nanoparticles into the paste matrix. under the optimized experimental conditions, using differential pulse voltammetry (dpv), the oxidation of thiocyanate and oxalate were occurred at potentials of 0.740 v and 1.010 v, respectively, at the surface of the modified electrode. observi...

a flow injection method is reported for the determination of ascorbic acid based on amperometric detection, using a cobalt(ii) phthalocyanine (copc) modified graphite-epoxy electrode. the amperometric respons was evaluated with regard to ph, ionic strength of the electrolyte, flow rate of the carrier solution, injected sample volume and conditioning time of the electrode. the limit of detection...

in this study, undoped zno and doped with fe and mn nanostructures were synthesized by hydrothermal method. the morphology of nanostructures was characterized by scanning electron microscope. the electrochemical response of the carbon paste electrode modified with nanoparticles of zno and also zno doped with fe and mn toward levodopa (l-dopa) was studied. studies of cyclic voltammetry using pro...
