The multiangle 3D cross-correlation instrument is a high precision optical instrument. It requires precise alignment of the mechanical and optical components. In particular it has be assured that both laser beams are focused into the same scattering volume and that the pair of detectors which is placed at a particular angle detects light scattered in this volume at exactly the same q-vector. In...

This paper describes a generic approach for analysis of internal behavior of logistic systems based on event logs. The approach is demonstrated by an example of event data from the simulation model of an automated material handling system (MHS) in a manufacturing company. The purpose of the analysis is the identification of design and operation problems and their causes, prospectively. As a res...

Humans can visually recognize material categories of objects, such as glass, stone, and plastic, easily. However, little is known about the kinds of surface quality features that contribute to such material class recognition. In this paper, we examine the relationship between perceptual surface features and material category discrimination performance for pictures of materials, focusing on temp...

everybody knows water as a vital material for human being. using water as a relaxation material which cause muscle smoothing and comfortable have been considered from long before. people of past centuries went to the thermal springs and immersed into them. today groups of people go to seaside for swimming in their vacation. children and adults go to pools for swimming or take a warm shower afte...

highly self-ordered alumina nanopore arrays were fabricated using hard anodization technique in different mixtures of oxalic/phosphoric acid. the phosphoric acid concentration was varied from 0.05 to 0.3 m while the oxalic acid concentration was changed between 0.3 and 0.4 m. the self ordered nanoporous arrays were obtained in anodization voltage changing from 130 to 200 v. the interpore distan...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

abstract textbooks play an important role in english language teaching (elt), particularly in the english as a foreign language (efl) context where it provides the primary linguistic input. the present research was an attempt to comparatively evaluate the touchstone series in terms of compliment and complaint speech acts. four touchstone textbooks (book 1, book 2, book 3, and book 4) were selec...

ginger waste material (gwm) has been utilized as adsorbent for removal of hazardouspatent blue vf (pbvf) dye from aqueous solution. batch adsorption experiments wereperformed as a function of ph, contact time, dye concentration, adsorbent dose and temperature.the optimum ph required for the maximum adsorption was found to be 2. the experimentalequilibrium adsorption data were tested using langm...
