ion: To allow easy creation of visual objects containing code to draw themselves, we should provide a higher-level drawing mechanism than the AWT‟s screen-coordinate system. Objects should be concerned only with drawing themselves in virtual space; whilst the Display should allow the user to navigate this virtual space by zooming, translating and rotating his view. The plan is to first build th...

One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...

Aquatic field studies were conducted in Tha Mai District, Chanthaburi Province, Thailand. Larval habitats of Anopheles dirus were examined from November 1986 through June 1988 in 42 manmade gem pits. Larvae were found in pits containing clear water under full or partial shade. The abundance of different kinds of mosquito larvae were related to seasonal changes in these aquatic habitats. Variati...

In order to analyze the influence of methods to design antireflection coatings (ARCs) on reflectivity of broadband solar cells, we provide detailed analyses about the ARC coupled with a window layer and the refractive index dispersion effect of each layer. By multidimensional matrix data simulation, two methods were employed to measure the composite reflection of a SiO2/ZnS double-layer ARC wit...

How might varying spatial organization improve memory for sets of objects? In this experiment simple line drawings of everyday objects were placed in grids that were regularly or irregularly organized at either a local or a global level, to give 4 layouts of stimuli that varied in the distinctiveness of their spatial organization of objects. Nineteen university students took part in six success...

Visual context is used in different forms for saliency computation. While its use in saliency models for fixations prediction is often reasoned, this is less so the case for approaches that aim to compute saliency at the object level. We argue that the types of context employed by these methods lack clear justification and may in fact interfere with the purpose of capturing the saliency of whol...

First we review an analysis of conditions that should be met if features are to provide robust inferences about world properties. Features meeting these conditions provide indices into especially useful categories of visual properties. Then we show that for a given set of elemental concepts the categories associated with these properties have a natural hierarchical (specialization) structure. W...
