Using historical cost data, we simulate the California electricity market after deregulation as a static Cournot market with a competitive fringe. Our model indicates that, under the pre-deregulation structure of generation ownership, there is potential for significant market power in high demand hours, particularly in the fall and early winter months when hydroelectric output is at its lowest ...
This paper presents an empirical analysis of the value of a coordinated market exchange mechanism. I present a model of e cient trading mechanisms under uncertainty, and develop a measure of the value of an inter rm trade agreement in the context of sequential `buy-versus-produce' decisionmaking by rms. The theory is applied to estimate the value of a formal trading institution in the Californi...
هدف از این پژوهش مقایسه تغییرات مکانی پارامترهای کیفیت فیزیکی خاک در اراضی جنگلی، کشت خورده و مرتعی منطقه فندقلو در استان اردبیل بود. نمونه برداری خاک به طور منظم و در قالب شبکه 100×100 متر مربع زمین انجام شد و موقعیت نقاط از طریق سیستم موقعیت یاب جهانی (gps) ثبت گردید. نمونههای دستخورده در آزمایشگاه هوا خشک گردیده و به منظور اندازهگیری خصوصیات خاک شامل جرم مخصوص حقیقی (dp)، توزیع اندازه ی ذ...
The influence of the moss layer on soil structure and water retention is not well understood. Therefore, this study aims to investigate changes in under reveal influencing factors these changes. 3D networks macropores were quantified using CT scanning image analysis techniques, characteristics explored through curves (SWRCs) VG model. length densities thin thick layers approximately 2.7 1.6 tim...
Background: Previous research indicates that Physical Activity (PA) can help people with Parkinson’s (PwP) to manage their symptoms but they are less active than of the same age and in relation PA guidelines. Common measures include questionnaires or accelerometers. Accelerometers not routinely used clinical services. Little has been conducted on PwP perceived feasibility utility using b...
تعیین پارامترهای سینتیکی و ضرایب استوکیومتری واکنش هیدروکراکینگ و بررسی سینتیکی واکنشهای گوگردزدائی و ازت زدائی در حضور هیدروژن که عنوان پروژه را تشکیل می دهد ابزاری لازم جهت مشابه سازی سیستم راکتوری هیدروکراکینگ برای طراحی صنعتی، کنترل راکتور و نهایتا دستیابی به دانش فنی (maximum isomerezation) isomax برشهای سنگین نفتی و تبدیل آنها به فرآورده های سبک و میان تقطیری (دیزل و کروسین) می باشد. درای...
introduction: educational justice is a process by which all those involved in education are pondering and seeking to establish it in their regulatory environments. this study aimed to investigate effective factors in an ideal educational justice and the current condition of educational justice from the students’ viewpoint and ultimately increase the awareness and understanding of authorities an...
This study has been achieved using Geo-Studio Finite Element Software in two sections. First, to the changes pore water pressure (PWP) within soil layers below Bashtapia Castle at different levels of river Tigris. The effect these was focus check slope stability Castle. On other hand, second section increase safety factor reinforcement spacings and lengths anchor’s rods. Modeling output showed ...
Nodal prices, congestion revenues, transmission capacity rights, and compensation for wire ownership are key concepts used to formulate claims about proposals to organize competitive and open transmission access. Underlying those claims are implicit assertions (folk theorems) concerning the regulation of transmission access, the determination of power ows, properties of economic dispatch, and t...
