This paper considers fuzzy subbundles of a vector bundle. We define the operations sum, product, tensor product, Hom, and intersection of fuzzy subbundles and in each case, we characterize the corresponding flag of vector subbundles. We then propose two alternative definitions of integrability on fuzzy subbundles of a given type and discuss their naturality, merits, and shortcomings. We do thes...

Many continuous control tasks have bounded action spaces and clip out-of-bound actions before execution. Policy gradient methods often optimize policies as if actions were not clipped. We propose clipped action policy gradient (CAPG) as an alternative policy gradient estimator that exploits the knowledge of actions being clipped to reduce the variance in estimation. We prove that CAPG is unbias...

Wireless communications is regarded as the most important development with wide range of applications. Advances and development in this field aim for fast and reliable communication. Orthogonal frequency division multiplexing signal provides high spectral efficiency and ease of implementation. But it suffers from high peak to average power ratio. This paper presents the effect of clipping ratio...

OBJECTIVES Using specific selection criteria to determine whether endovascular coiling as compared to neurosurgical clipping is associated with significant benefits, in terms of 1-year clinical outcomes and consumption of hospital resources, for the treatment of ruptured intracranial aneurysms in Hong Kong Chinese patients. DESIGN Retrospective study. SETTING University teaching hospital, H...

Understanding the mechanism of plant morphological plasticity in response to grazing and clipping of semiarid grassland can provide insight into the process of disturbance-induced decline in grassland productivity. In recent studies there has been controversy regarding two hypotheses: 1) grazing avoidance; and 2) growth limiting mechanisms of morphological plasticity in response to defoliation....

In order to determine aqueous extract effects of cool-season turfgrass mixture clipping on germination and seedling growth of four weed species, laboratory and outdoor pot experiments were done at the experimental laboratory and greenhouse of the Doroud Parks and Landscape Organization, located in Doroud, Lorestan, Iran. The first factor was the concentration of sport turfgrass clipping extract...

We report a case of simultaneous microsurgical clipping 5 cerebral aneurysms in patient with multiple the anterior brain.We analyzed existing treatment approaches to aneurysms, including endovascular isolation, clipping, as well surgical tactics subarachnoid hemorrhage. covered recommendations for screening, risks, and aneurysm isolation (single-stage multiple-stage).Using our own experience (s...

A new algorithm for clipping line segments by a rectangular window on rectangular coordinate system is presented in this paper. The algorithm is very different to the other line clipping algorithms. For the line segments that cannot be identified as completely inside or outside the window by simple testings, this algorithm applies affine transformations (the shearing transformations) to the lin...

background: waste produced in dental clinics has been the topic of investigations for many years. these waste materials have important health impacts and are hazardous to humans and the environment. objective: to investigating solid waste production and its management in dental clinics in gorgan, northern iran. methods: in this cross-sectional study, 45 of 143 public dental practices and 5 of 2...

ABSTRACT: In this paper a new algorithm has been proposed which can fix the problem of WeilerAtherton algorithm. The problem of Weiler-Atherton algorithm lies in clipping self-intersecting polygon. Clipping self-intersecting polygon is not considered in Weiler-Atherton algorithm and hence it is also a main disadvantage of this algorithm. In our new algorithm a self-intersecting polygon has been...
