An integrated electric power supply chain and fuel market network framework: Theoretical modeling with empirical analysis for New England

In this article, we develop a novel electric power supply chain network model with fuel supply markets that captures both the economic network transactions in energy supply markets and the physical network transmission constraints in the electric power network. The theoretical derivation and analysis are done using the theory of variational inequalities. We then apply the model to a specific case, the New England electric power supply chain, consisting of six states, five fuel types, 82 power generators, with a total of 573 generating units, and 10 demand market regions. The empirical case study demonstrates that the regional electric power prices simulated by our model match the actual electricity prices in New England very well. We also compute the electric power prices and the spark spread, an important measure of the power plant profitability, under natural gas and oil price variations. The empirical examples illustrate that in New England, the market/grid‐level fuel competition has become the major factor that affects the influence of the oil price on the natural gas price. Finally, we utilize the model to quantitatively investigate how changes in the demand for electricity influence the electric power and the fuel markets from a regional perspective. The theoretical model can be applied to other regions and multiple electricity markets under deregulation to quantify the interactions in electric power/energy supply chains and their effects on flows and prices. © 2009 Wiley Periodicals, Inc.

通道失配对GNSS阵列抗干扰性能的影响分析

卫星导航接收机极易受到电磁干扰的影响,基于阵列接收机的空时(频)抗干扰技术被证明是目前最有效的抗干扰手段。在工程实现时,阵列通道存在通道失配,本文以统计性能的评估方法评估了通道失配对阵列抗干扰性能的影响。研究结果表明,通道间群时延偏差和幅度失配是导致阵列抗干扰性能下降的主要因素,前者可通过增加空时滤波器阶数来消除影响,而后者对空时滤波器阶数不敏感,需要进行必要的校正。     

装备动力传动系统劣化度与参数表征研究

传统的维修保障计划规定只是关注装备零部件的故障诊断,并根据装备使用的摩托小时来确定。为克服维修保障的盲目性,从装备的整体性能随服役期的变化角度出发,研究装备的劣化程度及其参数表征,并以新一代装甲装备的动力传动系统为目标,通过试验和分析,得出发动机汽缸压缩压力、车辆的各挡最大稳定行驶速度、加速性可作为动力传动系统的劣化程度评价指标。这些参数易测、科学、量化。研究结果对装备保障和使用有重要的指导意义。

Insurgent courts in civil wars: the three pathways of (trans)formation in today’s Syria (2012–2017)

As part of research on the meso-foundations of conflict, the field of ‘rebel governance’ examines political institutions that regulate the affairs of civilians in wartime as well as their relations with armed actors. Judicial institutions play an important role in this and research has shown that they are widespread among both historical and current insurgencies. However, usually these bodies have been analysed in the context of one hegemonic faction like the Tamil Tigers in Sri Lanka and the Afghan Taliban. What is missing so far is an analysis of different pathways of (trans)formation of rebel courts. As exemplified by the three case studies of judicial institutions in Eastern Ghouta, Idlib and Aleppo, these are shaped by the distribution of power between ‘same-side’ groups, yielding unipolar, bipolar, or multipolar constellations. The analysis is located on the meso or movement level of insurgent social structures, complementing research on the micro and macro levels.
