Energy-Efficient Resource Allocation for Small-Cell Networks：A Stable Queue Perspective

The small-cell technology is promising for spectral-efficiency enhancement. However, it usually requires a huge amount of energy consumption. In this paper, queue state information and channel state information are jointly utilized to minimize the time average of overall energy consumption for a multi-carrier small-cell network, where the inter-cell interference is an intractable problem. Based on the Lyapunov optimization theory, the problem could be solved by dynamically optimizing the problem of user assignment, carrier allocation and power allocation in each time slot. As the optimization problem is NP-hard, we propose a heuristic iteration algorithm to solve it. Numerical results verify that the heuristic algorithm offers an approximate performance as the brute-force algorithm. Moreover, it could bring down the overall energy consumption to different degrees according to the variation of traffic load. Meanwhile, it could achieve the same sum rate as the algorithm which focuses on maximizing system sum rate.

A Distributed User Association and Resource Allocation Method in Cache-Enabled Small Cell Networks

Cache-enabled small cell networks have been regarded as a promising approach for network operators to cope with the explosive data traffic growth in future 5 G networks. However, the user association and resource allocation mechanism has not been thoroughly studied under given content placement situation. In this paper, we formulate the joint optimization problem of user association and resource allocation as a mixed integer nonlinear programming(MINLP) problem aiming at deriving a balance between the total utility of data rates and the total data rates retrieved from caches. To solve this problem, we propose a distributed relaxing-rounding method. Simulation results demonstrate that the distributed relaxing-rounding method outperforms traditional max-SINR method and range-expansion method in terms of both total utility of data rates and total data rates retrieved from caches in practical scenarios. In addition, effects of storage and backhaul capacities on the performance are also studied.

COMPREHENSMIVE PLANNING FOR WATER RESOURCES EXPLOITATION AND WATER POLLUTION CONTROL FOR CHANGLI COUNTY--A CASE STUDY FOR SMALL TOWNS OF CHINA

One of the major characteristics about the water resources and water pollution in China is that the southem part of the country is endowed with abundant water resources with serious water pollution occurring in some areas, whereas the northem part is endowed with limited water resources with relatively more serious water pollution existing in some areas. Urban areas have been mainiy affected by point source pollution while ecological damage is most serious in rural areas and small towns. With rapid development of socio-ecomony and urbanization, many new small towns have occurred in China, and the concemed ecological problems such as water pollution and soil erosion have been gradually changed into local point source pollution. Water envirormental problems are geding more and more serious. To resolve the above mentioned problems and to provide a mode for towns in North China, the Research Center of Water Problems of Chinese Academy of Sciences undertook the research project of comprehensive planning of urban environment of Changli County, Hebei Province. Conceming the limited financial strength of the county and its relatively low level of socio-economic development, the planning is aimed to protect and to improve Changli's environment with the least cost, to promote the suitable development of socio-economy of Changli County, and to carry out effective environmental regulations, control and managemeat.

Utilization and Management of Small Fishery Population Resources in Coastal and Offshore Areas of China

There are numerous types of living resources in coastal and offshore areas of China. In recent years,both the population type and quantity structure have significant changes,and the stock of small fishery population resources is increasing. This population is precious protein resource. It is urgent to study how to take prompt and effective fishing and take full advantage of processing,utilization and management. Traditional utilization methods are limited by many factors. The utilization efficiency is extremely low. The feed conversion rate of some mariculture fishes with fresh small trash fishes as feeds is even as low as 0. 2. Innovative production and management organization model with aquatic enterprises as leaders greatly increases the utilization efficiency of small fish resources with the aid of marine processing mother ship. In order to further accelerate developing and utilizing small fishery population resources in coastal and offshore areas,China should launch survey and utilization researches of small fishery population resources in coastal and offshore areas,formulate practical and feasible laws,regulations and policies,actively encourage and support autonomous innovative management mode of enterprises,and promote effective utilization and management of coastal and offshore fishery resources.

An Optimal Resources Configuration Scheme for Caching-Based Content Distribution in BackhaulLimited Small Cell Networks

In this paper, we study the problem of resource allocation in small cell networks with distributed caching, that is, how to divide the spectrum resources for backhaul and access in order to improve network performance. We formulate our concerned problem by using multi-dimensional Markov model. Our problem considers that each user may access multiple small cell base stations. We conduct simulation experiments to evaluate the performance of our proposed resource allocation scheme. Our simulation results show that the appropriate spectrum resource allocation is important to improve network performance.

Problems for water resources development in typical small karst drainage basins and countermeasures

In karst area water deficit is one of the main factors constraining sustainable economic development. In 1979 the comprehensive karstic observational field station was set up in Houzhai drainage basin located,\ in Puding county of Guizhou Province, which can represent most of the small karst drainage basins on the dividing line of the Guizhou Plateau. Geomorphology, water resources and water chemistry were investigated and observed. Based on comparisons of water supply with water demand and analysis of the main problems in water exploitation and utilization. it is found out that the water deficiency was not directly caused by the scarcity of natural water resources. The true reason is the insufficient capacity of water supply caused by the dismatch of the water and soil water resources which can be dealt with by building more irrigation works. Some solutions such as to build scientific basis for water exploitation and utilization and sustainable economic development in karst drainage basins on dividing line of the Guizhou Plateau.

Efficient Resource Allocation Scheme to Maximise Number of Users with Quality of Service Demands in Small Cells

Small cells have been regarded as an appealing technique to boost resource reuse ratio. On the other hand, their large-scale and self-organised tendency would complicate the interference environment of mobile networks. Meanwhile, traffic class is booming in recent years, which leads to higher demand for net- work designers on Quality of Service （QoS） provision, and therefore users＇ diverse re- quirements may not be guaranteed in sucff＇an interference limited scenario. To maximise the number of users with QoS demands as well as resource reuse ratio, we formulate the resource allocation problem into a multi-objective l0 norm form. It is shown to be NP hard, and an iterative method is employed to approach the optimal solution. Because of its limit of being not adaptive to large-scale networks, we also design a heuristic method based on chordal graph, which, however, could result in per- formance loss when the size of networks is small. Finally, by combining these two meth- ods, we devise a hybrid algorithm such that the allocation performs both efficiently and effectively. Simulation results illustrate the performance of our proposed methods in terms of outage probability and resource reuse ratio.

Human Resource Controlling and Human Resource Management： Practice of Small and Medium-Sized Building Companies in the Czech Republic

The aim of this paper is to define the nature, present the possibilities, and discuss the problems of using human resource controlling in small and medium-sized building companies. This paper is based on the assumption that expedient human resource controlling is an effective human resource management tool that achieves the required performance of employees and expected competitiveness of a building company. This paper uses the results of a questionnaire survey conducted in November 2013 to analyze human resource management in building companies in the Czech Republic and specify the organization and conditions of human resource management. Some 81 small （less than 50 employees） and 66 medium-sized （50-249 employees） building companies operating in the Czech Republic took part in the questionnaire survey. The results of the questionnaire survey showed the lack of concept and random nature of human resource management in most small and medium-sized building companies. Of course, in terms of the present economic trend, it is above all important for small and medium-sized companies to develop their adaptability to the building market and to be able to deal with a variety of construction works. It is effective human resource management supported by expedient human resources that serves this purpose.

气候变化对中国近海中上层小型鱼类影响的研究进展

近年来气候变化持续影响海洋环境,同时也影响着海洋鱼类的群落变化和生态系统的稳定。中上层小型鱼类对气候变化较为敏感,其在我国海洋渔业中逐渐占据重要地位。近年来,虽有大量的研究探究了气候变化对鱼类的影响,但是气候变化对中上层小型鱼类全面系统的研究相对较少。鉴于上述原因,本文根据国内外的相关研究成果,综述了由气候变化引起的海水表面温度、盐度、酸碱度、溶解氧含量、叶绿素a浓度、海平面上升以及海流和极端事件频发等海洋环境因子变化对海洋中上层小型鱼类的影响,这种影响主要体现在个体发育、栖息地、洄游模式、群落结构及其资源丰度等方面。气候变化下中上层小型鱼类的分布区通常向高纬度或深海区转移,从而导致群落结构改变,对渔业资源造成影响。本文通过探讨气候变化对海洋渔业的影响,旨在从中探寻应对气候变化的有效对策,从而为海洋渔业在气候变化的背景下实现可持续发展提供理论依据。
