multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. one of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...
The rapid development of information technology enables informationization to become the necessary means for medium-sized and small enterprises to improve their competitive advantages. With efforts for several years, establishment of informationization in medium-sized and small enterprises has achieved some achievements. However, because they started later, together with disadvantages of the en...
this study examined farmers’ perception and adoption of yam minisett technology. the study was carried out in anambra state, nigeria. a sample size of 120 yam farmers was used for the study. data were collected using a structured and validated interview schedule. data generated for the study were summarized using descriptive statistics such as frequency, percentage and mean scores while the sig...
In this study, we investigated the effects of foreign direct investment (FDI) spillovers on firm production and technical efficiency in Indonesia’s manufacturing sector from 2010 to 2015. We scrutinized three different channels horizontal spillover, namely, demonstration, technology adoption, competition channels. also captured heterogeneous effect firms by categorizing them based their t...
با توجه به اهمیت تالاب شادگان در محیط زیست ایران و افزایش آلودگی های منطقه، در پژوهش حاضر غلظت کل و منشایابی فلزات سنگین در رسوب تالاب شادگان مورد بررسی قرار گرفت. بدین منظور نمونه برداری از رسوب سطحی 10 ایستگاه با 3 تکرار صورت گرفت. جهت تعیین غلظت کل فلزات رسوب از روش (direct aqua regia)و برای آنالیز غلظت های فلزات در بخش های ژئوشیمیایی رسوب از روش استخراج پی در پی استفاده شد. آماده سازی نمونه...
the relationship between technology and international competitiveness dates back to the neo-technological trade theories of the 1960s. this approach considers difference in technology as the primary motive for difference among nations in terms of trade performance. the technology gap approach emphasizes inter-country differences in innovativeness as the basis for international trade flows. the ...
چکیدهاگر چه در گذشته تفاوت بین بخشهای فنّاوری بالا و متوسط (High-Medium Tech Sectors) با بخشهای فنّاوری پایین و متوسط (Low-Medium Tech Sectors) به طور گسترده مورد بررسی قرار گرفتهاست ولیکن بهدلیل کمبود اطلاعات مقایسه میان بخشهای فنّاوری بالا و متوسط با بنگاههای فنّاوریمحور (Technology Based Firms) انجام نشدهاست. هدف مقاله حاضر این است که این تفاوت را واکاوی کرده و نشاندهد که در کشور در حال...
This paper is concerned with the emergence and development of low-to-medium-grade thermal-energy-conversion systems for distributed power generation based on thermodynamic vapor-phase heat-engine cycles undergone by organic working fluids, namely organic Rankine cycles (ORCs). ORC power systems are, to some extent, a relatively established and mature technology that is well-suited to converting...
