In this paper we start off by reviewing the literature on how to extend the meanvariance portfolio model to multi-stage portfolio problems. We then apply a multiperiod portfolio selection model to power generation assets, which is based on a reallocation methodology with scenario tree. Two solution approaches are used: the multi-period rebalancing model and the global solution one. These approa...

Along with the reform in electric power market and the establishment of bidding for access mechanism, the competition among the power generation enterprises is more intense. As a kind of renewable clean energy, wind power has the disadvantages of no pollution, low cost, but the wind power also has the inherent shortcoming of intermittence, random and instability. To evaluate the core competitiv...

How should a monopolist price a durable good or a new technology that is subject to network externalities? In particular, should the monopolist set a low \introductory price" to attract a \critical mass" of adopters? In this paper, we provide intuition as to when and why introductory pricing might occur in the presence of network externalities. Incomplete information about demand or asymmetric ...

Lost River Winder Riders is a project designed to provide students with a challenging hands-on exercise in relational database design. It is extensive enough to provide a stimulating exercise, but not so large as to be overwhelming. This case can be used as an individual or team project in a database design course. It is sufficiently detailed to challenge students as they apply design concepts ...

Acknowledgments The author thanks her advisor, Dalia Patiño-Echeverri, for her time advising on the project, for giving feedbacks, and for providing new perspectives. She also thanks PhD students, Rubenka and Ali for their generous help.

Taiwan is located on the Pacific seismic belt, and the soil conditions of Taiwan’s offshore wind farms are softer than those in Europe. To ensure safety and stability of the offshore wind turbine supporting structures, it is important to assess the offshore wind farms seismic forces reasonably. In this paper, the relevant seismic and geological data are obtained for Chang-Bin offshore wind farm...

The use of wind energy for electricity generation is growing rapidly across the world and in Portugal. However, the geographical characteristics of the country along with the average wind regime and with the environmental restrictions imposed to these projects create limitations to the exploit of the onshore wind resource. The best onshore wind spots are already committed and the possibility of...

the purpose of this work is to study the conditions under which synchronisation is possible in asynchronous wind parks. Synchronisation is defined as the situation where blades of different wind turbines pass simultaneously in front of their towers. Tower shadow effect is generally considered responsible for part of power quality problems originated by wind turbines. The way of summing the effe...

test In this paper we study the problem of optimal layout of an offshore wind farm to minimize the wake effect impacts. Considering the specific requirements of concerned offshore wind farm, we propose an adaptive genetic algorithm (AGA) which introduces location swaps to replace random crossovers in conventional GAs. That way the total number of turbines in the resulting layout will be effecti...

The traditional architecture of Central Asia and the Middle East is the product of land, the local climate, and people’s culture. The human needs and the environment represented the most essential factors to be considered in their designs. The traditional and vernacular architecture of this region introduced many realistic solutions and devices to the local environmental problems such as the Wi...
