We illustrate how natural resource dependent and isolated communities manage their forest stock. Our model is based on field observations of the Eaglewood trade in Papua New Guinea. Using a dynamic model of household utility maximization and simulations, we analyze the impact of variations in the (monopsonistic) resource price on the households’ consumption choices and their allocation of effor...

This note offers a general proof of the converse of Hartwick’s rule, namely that — in an economy with stationary instantaneous preferences and a stationary technology — an efficient constant utility path is characterized by the value of net investments being zero at each point in time. In a one consumption economy with two stocks — a stock of a natural resource and a stock of man-made capital —...

Compared to current mobile networks, nextgeneration mobile networks are expected to support higher numbers of simultaneously connected devices and to achieve higher system spectrum efficiency and lower power consumption. To achieve these goals, we study the multi-sharing device-todevice (D2D) communication, which allows any cellular user equipment to share its radio resource with multiple D2D d...

Multi-hop wireless sensor networks are mainly designed for environment monitoring. The lifetime of networks depends on the durability of the battery resource sensors, so it is crucial for sensors to efficiently use limited battery resource. The energy expends by sensor nodes in communication makes-up a quantum of their total amount of energy consumption. In existing research, most of the energy...

Most mobile video applications are often operated on battery energy supply devices. The higher resolutions and complex functionality of video applications need high resource requirements. Thus, power efficient design plays an important role in computation intensive applications especially for video encoding systems. This paper proposed a power-scalable video encoding scheme (PSVE) for energy li...

This paper attempts to propose hybrid methodology of compiling water resource extended input-output (IO) table at county level (According to administrative structure of China, a county is subordinate to its province, and provincial level is parallel to state level of other countries). By combining Non-Survey-based RAS-technique for possible iterated results and Partial-Survey-based current situ...

In the framework of a wide foresight process, launched by the Standing Committee on Agricultural Research (SCAR) and aiming to identify possible scenarios for European agriculture in a long-term perspective, the European Commission (DG RTD-E4) established a “3rd Foresight Expert Group” that conducted a scanning and monitoring exercise of recent relevant foresight activities undertaken by nation...

For Video-On-Demand (VOD) systems, it is important to provide Quality of Service (QoS) to more clients under limited resources. In this paper, the performance scalability in cluster-based VOD servers is studied with several grouping configurations of cluster nodes. To find performance bottlenecks, the monitoring functions are employed and the maximum QoS streams are measured under the various r...

Web service deployment is hampered by the possibility of sudden variations in request volumes. Mechanisms exist to enhance scalability in times of heavy load when the delivered content is static. However, web services typically involve dynamic content, delivered through application servers which may have little to no support for adapting to varying loads in order to ensure timely delivery. In t...

The increasing use of more resource-intensive multimedia applications in communication has made it essential to ensure better utilization of available computing resources. At the same time, energy consumption has turned out to be one of the most important resource constraints in modern systems. Digital videos are an important part of multimedia, and a large number of video standards are current...
