maximum Utility Principle slide handover strategy for multi antenna cellular architecture
Vehicular Technology Conference, 2008Co-Authors: Xiaodong Xu, Ying Wang, Zhongqi ZhangAbstract:This paper proposes maximum Utility Principle slide handover strategy for multi-antenna cellular architecture. Based on generalized distributed cellular architecture-group cell, slide handover strategy is illustrated and its merits are presented. Slide antenna window is applied by slide handover in the handover process, which makes users always in the cell centre and eliminates cell-edge effect. But for traditional slide handover, the handover rules of adding new antenna elements and replacing or releasing existing antenna elements are only by the pilot strength of each antenna element. This will constrain the performance of slide handover. Therefore, the rules need to be enhanced. Maximum Utility Principle slide handover strategy, proposed by this paper, can effectively solve this problem. The Utility function in the slide handover and steps for handover are described in this paper and system-level performance evaluation is provided with comparison of traditional slide handover to verify the merits of maximum Utility Principle slide handover strategy.

maximum Utility Principle access control for beyond 3g mobile system
Wireless Communications and Mobile Computing, 2007Co-Authors: Xiaofeng Tao, Ying Wang, Ping ZhangAbstract:With current research focusing on beyond 3G (B3G)/4G mobile systems, many advanced techniques are investigated by world-wide research institutes and standard organization, such as multi input multi output (MIMO), orthogonal frequency division multiplex (OFDM), and multi-antenna distributed cellular network architecture. Based on these novel techniques, the radio resource management (RRM) strategies, such as access control, also need to be developed. This paper proposes the maximum Utility Principle access control (MUPAC) basing on Dijkstra's Shortest Path Algorithm for multi-antenna cellular network architectures. In the accessing process of the proposed algorithm, the shortest path in Dijkstra's Algorithm is replaced by the cost of accessing process, which is represented by Utility function. Taking Generalized Distributed Cellular Architecture—Group Cell as an example, MUPAC is described in details with the Utility function, maximum Utility Principle, flow chart of accessing process. Performance evaluation and analyses verify the merits of MUPAC algorithm in improving system capacity, accessing success probability, and efficiency of system resources usage.

Evaluating the marginal Utility Principle for long-term hydropower scheduling
Energy Conversion and Management, 2015Co-Authors: Tongtiegang Zhao, Jianshi Zhao, Pan Liu, Xiaohui LeiAbstract:Abstract The conversion of the potential energy of dammed water into hydropower depends on both reservoir storage and release, which are the major difficulties in hydropower reservoir operation. This study evaluates the marginal Utility Principle, which determines the optimal carry-over storage between periods, for long-term hydropower scheduling. Increasing marginal cost and decreasing marginal return are two important characteristics that determine the marginal Utility Principle in water supply. However, the notion of decreasing marginal return is inapplicable in hydropower scheduling. Instead, the carry-over storage from one period has an increasing marginal contribution to the power generation in the next period. Although carry-over storage incurs an increasing marginal cost to the power generation in the current period, the marginal return is higher than the marginal cost. The marginal return from the carry-over storage further increases in the multi-period case. These findings suggest saving as much carry-over storage as possible, which is bounded by the operational constraints of storage capacity, environmental flow, and installed capacity in actual hydropower scheduling. The marginal Utility Principle is evaluated for a case study of the Three Gorges Reservoir, and the effects of the constraints are discussed. Results confirm the theoretical findings and show that the marginal return from carry-over storage is larger than the marginal cost. The operational constraints help determine the optimal carry-over storage.

characterization theorems for customer equivalent Utility insurance premium calculation Principle
European Actuarial Journal, 2014Co-Authors: Mykola Pratsiovytyi, Vitaliy DrozdenkoAbstract:Characterization theorems for several properties possessed by the customer equivalent Utility insurance premium calculation Principle are presented. Demonstrated theorems cover cases of additivity, consistency, iterativity, and scale invariance properties. Results are formulated in a form of necessary and sufficient conditions for attainment of the properties imposed on customer’s Utility function. Obtained theorems are also valid for the customer zero Utility premium calculation Principle. We also demonstrate that for the customer zero Utility Principle subjected to pricing of only strictly positive risks, the class of the Utility functions producing scale invariant premiums is larger than in the general case.
