In this research, a simulation system based on physical model and its lighting feature is developed to perform three-dimensional creation, graphics software used randomly generate simulated surface with defects, which also cooperates the virtual environment reproduce original environment. Furthermore, use of generative adversarial network optimize dataset created symmetrically by studied in ord...

BACKGROUND Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death. Many treatments have been proposed but considerable uncertainty still remains about their effectiveness. In this review we evaluated the quality, clinical coherence, consistency and results of Randomized Controlled Trials (RCT) of non-surgical treatments for HCC. METHODS Thirty-seven RCTs examining the effec...

One of the problems with today's TCP/IP networks is their transmission system. If bandwidth a network full, human and physical factors must be used for new system higher capacity to provide its bandwidth, which very time consuming costly. In this article, we proposed method that in addition optimal use available if it will automatically transferred network. For purpose first, by designing fuzzy...

Epistemic uncertainty is a huge area of scholarship. It has captured the minds of scholars in psychology and many domain-specific studies of reasoning and problem solving. What does it mean to resolve uncertainty? This chapter explores the idea that resolution of uncertainty in complex science and engineering fields frequently ends with approximations rather than precise answers. The chapter be...

This paper investigates the automatic berthing problem of underactuated surface vessels in case uncertain dynamics and yaw rate limitation, given importance control unmeasurable hydrodynamic parameters vessel at low speeds. First, we use differential homeomorphism coordinate transformation to solve underactuation. Second, a radial basis function network (RBF) is introduced approximate unknown n...

Reportedly, guaranteeing the controllability of the estimated system is a crucial problem in adaptive control. In this paper, we introduce a recursive least squares-based identiication algorithm for stochastic SISO systems , which secures the uniform controllability of the estimated system and presents closed-loop identiica-tion properties similar to those of the least squares algorithm. The pr...

Text is most used means for information exchange in today’s web dominated world. Text Mining also known as text data mining, an equivalent of text analytic, means the process of retrieving high quality information from text. Statistical pattern learning helps to devise patterns and trends through which high quality information is derived. Text mining accomplishes the task of structuring the inp...

Pulmonary arterial hypertension (PAH) is associated with symptoms of dyspnea and fatigue, which contribute to exercise limitation. The origins and significance of dyspnea and fatigue in PAH are not completely understood. This has created uncertainly among healthcare professionals regarding acceptable levels of these symptoms, on exertion, for patients with PAH. Dysfunction of the right ventricl...

Rural markets offer a great scope for a concentrated marketing effort because of the recent increase in the rural incomes. Such incomes will increase faster because of better production and higher prices for agricultural commodities. Rural marketing is a developing concept, and the marketers have realized the opportunity of growth in the market recently. Any macro level strategy for these marke...
