This paper presents an analytical model for downlink rate allocation in Code Division Multiple Access (CDMA) mobile networks. By discretizing the coverage area into small segments, the transmit power requirements are characterized via a matrix representation that separates user and system characteristics. We obtain a closed-form analytical expression for the so-called Perron-Frobenius eigenvalu...

The quality of a selection decision is a function of the decision rule used and the data collected to support the decision. When physical measurements are the basis of the decision data, the measurement sampling scheme controls measurement uncertainty and influences decision quality. Faced with a fixed experimental budget for measurement collection over multiple attributes, a decision-maker mus...

Andersson, M. 2002. Spatial allocation of forest production Aspects on multipleuse forestry in Sweden. ISSN: 1401-6230, ISBN: 91-576-6341-6 The question of how production of different services and goods should be combined or allocated spatially is an issue that often have been discussed during the evolution of the concept multiple-use forestry. Basically there are two different approaches: the ...

This paper presents a combinatorial algorithm for downlink rate allocation in Code Division Multiple Access (CDMA) mobile networks. By discretizing the coverage area into small segments, the transmit power requirements are characterized via a matrix representation that separates user and system characteristics.

Beacon scheduling is considered to be one of the most significant challenges for energy-efficient Low-Rate Wireless Personal Area Network (LR-WPAN) multi-hop networks. The emerging new standard, IEEE802.15.4e, contains a distributed beacon scheduling functionality that utilizes a specific bitmap and multi-superframe structure. However, this new standard does not provide a critical recipe for su...

The allocation problem stems from the diversification effect observed in risk measurements of financial portfolios: the sum of the “risks” of many portfolios is larger than the “risk” of the sum of the portfolios. The allocation problem is to apportion this diversification advantage to the portfolios in a fair manner, yielding, for each portfolio, a risk appraisal that accounts for diversificat...

Routing allocation scheme is a core issue in agricultural machinery allocation. It is related to the allocation cost, income and timeliness of crop harvest. How to select a farmland spot to harvest, which needs to consider not only the distance between a farmland spot and an agricultural machinery spot, but also road condition, farmland area, types of agricultural machinery and weather conditio...

range wireless multimedia applications, the mmWave wireless personal area networks with directional antennas are gaining increased interest. Due to the use of directional antennas and mmWave communications, the probability of non-interfering transmissions increases in a localized region. The network throughput can immensely increase by the concurrent time allocation of non-interfering transmiss...

In order for a team of autonomous robots to perform a complex mission effectively, an efficient assignment of tasks to robots must be determined. Existing multirobot task allocation algorithms treat tasks as simple, indivisible entities. However, when dealing with complex tasks, the structure and semantics of the tasks can be exploited to produce more efficient team plans by giving individual r...

ABSTRACT- Inadequate water supply is the major problem for agriculture in arid and semi-arid regions. Thus, effective management should be considered for water resources planning. In this research, a model was provided which is able to estimate optimal land and water allocation in the Doroodzan irrigation network. Optimal water management model was used at farm level to evaluate different defic...
