This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...

The rural residential land functions are the comprehensive embodiment of storage quantity and structural organization man–land system. Mastering evolution rule allocation situation is basis effective management targeted poverty alleviation activities. Based on theoretical understanding multifunction, this paper identifies five functional types characteristic elements uses a variety methods to c...

5 Calibration and validation of the Land Use Scanner allocation algorithms The Land Use Scanner is a spatial model that simulates future land use. Since its development in 1997, it has been applied in many policy-related land-use projects. In 2005, a completely revised version became available. In this version, land use can be modelled on a reduced scale, the smallest resolution now being 100 m...

Land registration and cadastral systems exist in great variety. This paper describes the rich history of Zambian land tenure systems and discusses the present land tenure system. Zambia has a dual land tenure system: customary tenure and formal title registration. In the customary system the chiefs regulate the allocation of the land. They rule with the consent of their people. This system is c...

structural characteristics and spatial distribution of major farming systems in mountain environment of the iranian plateau as well as their developments in the past few decades have been studied by statistical analysis. using this new approach, towards the study of natural resource allocation methods in mountains of iran, the following resulted: land and resource use practices have followed a ...

location-allocation is a combinatorial optimization problem, and is defined as non deterministic polynomial hard (np) hard optimization. therefore, solution of such a problem should be shifted from exact to heuristic or meta heuristic due to the complexity of the problem. locating medical centers and allocating injuries of an earthquake to them has high importance in earthquake disaster managem...
