The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions. The results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. This is due to the Ti(CN) and TiC precipitates and also the free carbon content. In the ferrite reg...

The response speed of Web pages is one of the necessities of information technology. In recent years, renowned companies such as Google and computer scientists focused on speeding up the web. Achievements such as Google Pagespeed, Nginx and varnish are the result of these researches.

the category of verb as the nucleus of sentence has a significant importance in grammar. this grammatical category has specific semantic and syntactic characteristics in different languages. in role and reference grammar as a functional grammar, predicates are classified into five classes including states, activities, achievements, accomplishments and active-accomplishments. these five classes ...

Background:The main goal of physiotherapy for patients with anterior cruciate ligament reconstruction (ACL-R) is to improve postural control and retain knee function. Therefore, clinicians need to use evaluative tools that assess postural changes during physiotherapy. To maximize the clinical utility of the results of these tools, the extracted measures should have appropriate psychometric prop...

In this paper, a detailed mathematical model of a grid-connected micro-grid including wind-turbine, photo voltaic cells, CHP and Fuel Cell with respective uncertainties in electrical loads, thermal loads, PV and wind outputs are presented. Moreover, the effects of the considered uncertainties on the micro-grid’s operation cost are modeled as risk and this risk is reduced using Monte-Carlo...

data envelopment analysis (dea) is a managerial powerful tool for assess the performance of decision making units (dmus). nowadays, multi-objective dea models are an attractive technique for evaluation quantity and quality aspects of performance analysis. but these models are in static. in this paper, we want to present a proposed fuzzy dynamic multi-objective dea model in which data are changi...

network expansion studies normally offer new power lines, new substations or expansion of existing substations. they are generally proposed based on technical requirements, but financial restrictions are not considered. because of financial restrictions, ranking of network expansion plans is required. in this paper an algorithm for such ranking, based on technical and financial view points and ...

this study compares and contrasts tense and inherent aspect in english and persian lan-guage from a semantic and syntactic point of view. the aspectual verb system in both english and persian are semantically interpreted alike. however, in persian a group of stative verbs are grammaticalized by the imperfective obligatory morpheme mi-, while in english all sta-tive verbs perfective. furthermore...

the paper presents a mathematical base modeling combined to modified-winding -function-approach (mwfa) for eccentricity fault detection of a round-rotor synchronous machine. for this aim, a 6-pole machine is considered, and the machine inductances are computed by mwfa in healthy and also under eccentricity fault. a numerical discrete-time method has been proposed to machine modeling in voltage-...
