In this paper, I introduce the theorems in Professor Hukukane Nikaido’s work, “Coincidence and some systems of inequalities,” published in the Journal of Mathematical Society of Japan, 1959, and note the significance of his mathematical methods on the history and the future of mathematical economics. Nikaido (1959) may be considered a compilation of his works of the 1950’s on economic equilibri...

This paper examines Nash jurisdictional stability in a model with a continuum of agents whose characteristics are distributed over a unidimensional interval. Communal benefits and costs of each individual depend on her identity and the composition of the community which she belongs to. Since the framework is too general to yield an existence of Nash equilibrium, we introduce the essentiality of...

اندازه‌گیری پرتو گاما در زمینه‌های مختلف تحقیقاتی نیازمند آشکارسازهای کارآمد است. زمینه دزیمتری فوتون آشکارساز جرقه‌ای NaI(Tl) به عنوان یکی از سوسوزن معدنی (غیرآلی)، علت دارا بودن مقدار بالای نور خروجی بسیار حایز اهمیت این پژوهش سعی گردیده است، با کمک کد مونت‌کارلو (MCNPX) مقدمات مشخصه‌یابی توسط و بهره‌گیری روش‌های متفاوت محاسبه دز (تالی‌های 6F، 4*F، 6+F 8*F) انجام شود. طور معمول، یک تابش (شمار...

Recent nuclear sequence analyses have provided evidence that primates and rodents are more closely related than previously believed (Madsen et al. 2001; Murphy et al. 2001a, 2001b). This proposal is difficult to reconcile with morphological insights (Liu et al. 2001; Novacek 2001) and is not generally supported by current mitochondrial sequence data (Reyes, Pesole, and Saccone 2000; Nikaido et ...

این مقاله حاصل پژوهشی درباره قیمت‌گذاری و تبلیغ پویا است با استفاده از یک مدل کنترل بهینه، روشی برای تعیین تعداد بلیت فروش رویداد ورزشی یا تفریحی به­دست می­‌دهد تا سود برگزارکننده بیشینه شود؛ همچنین سعی شده حد ممکن هزینه پشتیبانی در این­گونه رخدادها نظیر غذا، نوشیدنی، کالاها، بیمه، امکان واگذاری رایگان سایر خدمات به خریداران نظر گرفته شود. روش، علاوه بر بلیت‌­ها (برنامه‌­ریزی ظرفیت)، قیمت پویای...

This paper investigates the competition problem between electric vehicle charging and parking desks for different owners using a non-cooperative Bertrand game. There is growing attention on vehicles from both policy makers public service provider, as well owners. The interaction entities forms (game), especially multi-type facilities. Most of existing studies platforms are about optimization pl...

Demand response modelling have paved an important role in smart grid at a greater perspective. DR analysis exhibits the of scheduling appliances for optimal strategy user’s side with effective pricing scheme. In this proposed work, entire model is done three different steps. The first step develops patterns users considering integration renewable energy and demand done. second process learning ...
