in order to study the effects of shading on head and its near leaves on yield and yield components of spring safflower genotypes, an experiment was conducted in factorial arrangement based on a complete randomized block design with four replications at agricultural research station, faculty of agriculture, birjand university during 2008. factors were including three spring safflower genotypes (...

There are many kinds of façade shading designs which provide optimal indoor daylighting conditions. Thus, considering combinations of different types of façade shading systems is an essential aspect in the optimization of daylighting in the building design process. This study explores (1) how the pattern and different characteristics are evaluated by varying façade shading types and considering...

This study presents a contribution to the characterization of occupants’ behavior regarding the manual control of electric lighting in combination with shading control in offices. The procedure and monitoring results for eight single-occupied office spaces is described. The analysis of the collected data indicated that occupants kept electric lighting On during most of the monitoring period and...

This B.Sc. project deals with mesh pattern avoidance in permutations. A mesh pattern is a pair p = (τ,R), where τ is a permutation in Sk and R ⊆ J0, kK × J0, kK. The elements of R denote lled boxes in a mesh pattern. For a permutation π to contain a mesh pattern, it has to contain the underlying classical pattern τ , and no points in π can be located in the shaded boxes. In this paper we begin ...

It was shown from geometry and photographic measurement that the shading pattern for a sinusoidal corrugated surface of frequency f approximates to a luminance-defined grating of frequency f, 2f or f + 2f in specific relative phase. It was confirmed that a luminance grating modifies the appearance of a suprathreshold stereoscopic corrugated surface, suggesting an interaction between shading and...

Light is the origin of vision. The pattern of shading reflected from object surfaces is one of several optical features that provide fundamental information about shape and surface orientation. To understand how surface and object shading is processed by birds, six pigeons were tested with differentially illuminated convex and concave curved surfaces in five experiments using a go/no-go procedu...

Panicum maximum cv. Mombasa is a type of grass that known resistant to shade and responsive fertilization. This study aimed determine the morphology production on various levels shading organic fertilizer. The soil used in this was brown latosol. completely randomized design (CRD) with factorial pattern consisting three (0%, 36%, 72%) two dose factors fertilizer (0 g/pot 500 g/pot). parameters ...

The 'colour-shading effect' describes the phenomenon whereby a chromatic pattern influences perceived shape-from-shading in a luminance pattern. Specifically, the depth corrugations perceived in sinusoidal luminance gratings can be enhanced by spatially non-aligned, and suppressed by spatially aligned sinusoidal chromatic gratings. Here we examine whether colour contrast can influence perceived...

This article describes an approach to array design that results in the construction oftransducers producing precisely controlled radiation patterns. The method of dense random arrays employs an array of equally weighted elements, randomly distributed with a density distribution that matches a desired shading. As the spatial density of elements increases, the theoretical radiation pattern approa...

light intensity is considered a limiting factor in greenhouse rose production. the main aim of this experiment was to evaluate the effect of shading treatments (0, 25, 50, and 65% shading) on quality and chlorophyll content of cut rose (rosa hybrida cv. avalanche), under greenhouse conditions. the experiment was planned in randomized completely block design with four replications. all shoots we...
