With the increase of importance of bioenergy, the whole tree harvesting system was reconsidered. As a simple way of a whole tree harvesting system, this study analyzed two winching procedures in terms of productivity and influence from terrain conditions. One of the winching procedures was observed on flat terrain, where the felled trees were scattered and then, one-by-one, attached to the winc...

This work introduces two complementary techniques to improve the packet loss resilience of scalable video coding systems. First, a “switch per-pixel” error concealment (SPEC) scheme is proposed, which allows the decoder to exploit information from both the current base layer and previous enhancement-layer frame for the reconstruction of missing enhancement-layer blocks. Based on the packet loss...

Arboreal habitats pose unique challenges for locomotion as a result of their narrow cylindrical surfaces and discontinuities between branches. Decreased diameter of branches increases compliance, which can pose additional challenges, including effects on stability and energy damping. However, the combined effects of substrate diameter and compliance are poorly understood for any animal. We quan...

Automatic visual inspection of wire ropes is an important but challenging task. Anomalies in wire ropes usually are unobtrusive and their detection is a difficult job. Certainly, a reliable anomaly detection is essential to assure the safety of the ropes. A one-class classification approach for the automatic detection of anomalies in wire ropes is presented. Different well-established features ...

Plyometric training is widely used to improve force production, power and jumping ability through specific muscle action called the stretch shortening cycle (SSC). The SSC involves a powerful concentric contraction preceded by rapid eccentric contraction. The efficacy of the SSC is mainly related to the storage of elastic energy during eccentric contraction and its quick release during concentr...

In an archaeological experiment, the hypothesis was tested whether replica of a perforated bâton percé with four spiral holes made from mammoth ivory, which excavated in 2015 at Hohle Fels Cave Schelklingen, is suitable for making ropes. For this purpose, author has experimentally carved object tools based on corresponding devices Upper Paleolithic. Leather cords were used to make rope, fed thr...

OBJECTIVE We have previously reported that grafting fibroblasts genetically modified to express brain-derived neurotrophic factor (BDNF) into a subtotal cervical hemisection site that destroys the entire lateral funiculus will promote regeneration of rubrospinal axons and growth of other axons, prevent atrophy and death of axotomized red nucleus neurons, and improve forelimb use during spontane...

This paper is concerned with performance optimization of point-to-point communication of scalable video over lossy networks. The premise of the work is: (i) Decoder drift due to prediction should be controlled but not altogether disallowed; and (ii) Reaping the full benefits of drift management techniques requires accurate estimation of end-to-end distortion. A variant of the recursive optimal ...

Dataand task-parallelism are two important parallel programming models. Object-oriented paradigm in parallelism provides a good way of abstracting out various aspects of computations and computing resources. Using an object-oriented language like C++, one can compose data and control representations into a single active object. We propose a thread model of parallelism that addresses both data a...
