We explore dynamic shaping to integrate our prior beliefs of the final policy into a conventional reinforcement learning system. Shaping provides a positive or negative artificial increment to the native task rewards in order to encourage or discourage behaviors. Previously, shaping functions have been static: the additional rewards do not vary with experience. But some prior knowledge cannot b...

introduction: several treatment options have been introduced for removal of gingival hyperplasic lesions, but using diode lasers have many advantages such as less bleeding, time saving, better shaping, improved healing and less complication for the patients. case: a 15-year-old girl with multiple fibroma-like lesions in the oral cavity, who had a medical history of tuberous sclerosis, was selec...

human factors are among the main elements affecting the reliability of nondestructive examinations (nde). in a man-machine system, human reliability is affected by many factors (performance shaping factors) whose influence on reliability cannot be easily expressed quantitatively. this paper identifies and ranks 59 perform-ance shaping factors by using a fuzzy reasoning method and proposes a pro...

INTRODUCTION The aim of this study was to compare the shaping ability of two single-file systems and conventional rotary instruments in severely curved root canals of extracted human molars. METHODS AND MATERIALS Mesiobuccal canals of 120 mandibular molars with angles of curvature ranging between 25(°) and 35(°) and radii of curvature from 5 to 9 mm, were divided into three groups (n=40). In ...

Nowadays, people live in a society that has fuelled the growth of information delivered across many communication channels. Technology has enabled the ‘knowledification’ of our society (providing information through digital means). Undoubtedly, the Internet is the world’s largest communication network which has ported data across various conduits to provide information and in many ways, continu...

The main motivation for this research is the increasing popularity received by mobile and pervasive computing applications in combination with the increased complexity which is involved in the development of software systems targeting such environments. In this respect, two basic dimensions are detected: environment sensing and environment shaping. The former refers to the ability of systems to...

Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying (OQPSK) are two wellaccepted modulation techniques used in Code Division Multiple Access (CDMA) system. The Pulse-Shaping Filters play an important role in digital transmission. The type of Pulse-Shaping Filter used, and its behavior would influence the performance of the communication system. This in turn, would have...

The increasing demand of achieving high data rates in modern communication systems requires highly efficient bandwidth utilization. For this purpose, multilevel modulation schemes are used in association with forward error correction (FEC) codes in order to approach the channel capacity. However, there is a gap between the capacity of a uniform signal constellation and the Shannon unconstrained...
