Forest roads are the most important elements of forestry projects, the management, supervision, care, and only access way to the forest for mechanized harvesting and using other services of forests. The aim of this study was to compare the current annual increment of basal area in different distances from the road in northern forests of Iran. For this purpose, 50 plots were established in 5 dis...

The WebCOSY system is an interactive web-based homework and course management system that has been developed and used as part of VUBeam (Berz & Hoefkens, 2001), an Internet based remote Physics M.S. and Ph.D. program at Michigan State University. Besides supporting problems written within the system, it has the unique feature of also supporting processing and grading of student’s submissions by...

OBJECTIVE To evaluate the impact of distance education in diarrhea and cholera case management on the quality of physicians' and nurses' practice. DESIGN The pre-post panel, program and control group design used trained physician observers to measure if doctors and nurses complied with case management standards. Extended observations and client exit interviews were used to analyze audience bi...

Traditional caches employ the LRU management policy to drive replacement decisions. However, previous studies have shown LRU can perform significantly worse than the theoretical optimum, OPT [1]. To better match OPT, it is necessary to aggressively anticipate the future memory references performed in the cache. Recently, several researchers have tried to approximate OPT management by predicting...

This paper presents a mobile tracking scheme that exploits the predictability of user mobility patterns in wireless PCS networks. Instead of the constant velocity fluid-flow or the random-walk mobility model, a more realistic Gauss-Markov model is introduced, where a mobile’s velocity is correlated in time to a various degree. Based on the Gauss-Markov model, a mobile’s future location is predi...

We consider the optimal spacing between marine reserves for maximising the viability of a species occupying a reserve network. The closer the networks are placed together, the higher the probability of colonisation of an empty reserve by an occupied reserve, thus increasing population viability. However, the closer the networks are placed together, the higher the probability that a catastrophe ...

Conflicting evidence affects the final target recognition results. Thus, managing conflicting efficiently can help to improve belief degree of true target. In current research, existing approaches based on entropy use itself measure conflict. However, it is not convincing characterize conflict only through itself. To solve this problem, we comprehensively consider influences and mutual measurem...
