In this paper, we propose a Perceptual LOD (Level of Detail) system based on a skeleton structure by integrating the concepts of the human perceptual system and 3D skeletons into the weighting mechanism of error metrics for mesh simplification. The human reception system refers to the way a human being identifies a graphic object. It consists of “template-matching theories”, “prototype-matching...

Chlamydomonas acidophila Negoro is a green algal species abundant in acidic waters where inorganic phosphorus (P(i)) and carbon (CO(2)) are considered the most important growth-limiting nutrients for the phytoplankton. This paper describes the P(i) uptake and growth kinetics under varying carbon supply by cultivating the alga autotrophically, with and without CO(2) aeration, and osmo-mixotrophi...

We survey some recent results on efficient margin-based algorithms for adaptive sampling in binary classification tasks. Using the so-called Mammen-Tsybakov low noise condition to parametrize the distribution of covariates, and assuming linear label noise, we state bounds on the convergence rate of the adaptive sampler to the Bayes risk. These bounds show that, excluding logarithmic factors, th...

background: work clothing can limit heat exchange between humans and the environment and cause thermal strain and heat-related disorders in workers. it can thus reduce both efficiency and productivity. the purpose of this study was to examine the effects of work clothing material on physiological strain index (psi) in climatic chamber. methods: an interventional study was conducted on 18 male s...

Low-rank matrix recovery addresses the problem of recovering an unknown low-rank matrix from few linear measurements. Nuclear-norm minimization is a tractible approach with a recent surge of strong theoretical backing. Analagous to the theory of compressed sensing, these results have required random measurements. For example, m ≥ Cnr Gaussian measurements are sufficient to recover any rank-r n×...
