Heliostat blocking and shadowing efficiency in the video-game era
Blocking and shadowing is one of the key effects in designing and evaluating a thermal central receiver solar tower plant. Therefore it is convenient to develop efficient algorithms to compute this effect. In this paper we explore the possibility of using very efficient clipping algorithms developed for the video game and imaging industry to compute the block and shadowing efficiency of a solar...
متن کاملHeliostat Field Optimization: A New Computationally Efficient Model and Biomimetic Layout
In this article, a new model and a biomimetic pattern for heliostat field layout optimization are introduced. The model, described and validated herein, includes a detailed calculation of the annual average optical efficiency accounting for cosine losses, shading & blocking, aberration and atmospheric attenuation. The model is based on a discretization of the heliostats and can be viewed as ray...
متن کاملShadowing and Blocking as Learning Interference Models
The link between reward and reward-eliciting actions may be impaired by increased sensitivity to background noise during the waiting period (Shadowing) and may also be interfered simultaneous presentation of two redundant inputs. Clinical studies have shown acute Schizophrenia patients lack the ability to blocking (learning interference). The model presented in this study aims to illustrate the...
متن کاملA Particle Swarm Optimization Algorithm for Mixed-Variable Nonlinear Problems
Many engineering design problems involve a combination of both continuous anddiscrete variables. However, the number of studies scarcely exceeds a few on mixed-variableproblems. In this research Particle Swarm Optimization (PSO) algorithm is employed to solve mixedvariablenonlinear problems. PSO is an efficient method of dealing with nonlinear and non-convexoptimization problems. In this paper,...
متن کاملThe Effect of Teaching Metacognitive Listening Strategy during Shadowing Activity on Field-Dependent and Field-Independent EFL Learners’ Listening Comprehension
This study aimed to compare the effect of teaching metacognitive listening strategies through shadowing activity on the listening comprehension of field-dependent (FD) and field-independent (FI) EFL learners. Since the researcher had access only to female participants,85 female EFL learners from a language institute in Tehran, at the pre-intermediate level of proficiency with the age range of 1...
