Even though real-time data access to remote sensor data is desirable for many WSN applications, collecting remote data reliably from a WSN is a challenging task since many components of the WSN are subject to harsh elements of nature. A deployed system’s performance and lifetime can be impaired if this harsh environment of the deployment site is not considered. The deployments of LUSTER, a WSN ...

Hair shine or luster is perceived as an important, though analytically somewhat elusive, attribute of beauty, primarily associated with clean and healthy hair. Principles for the assessment of hair luster are developed that are consistent with the practical situation. These principles are related to the components of light, specularly and diffusely reflected from single hair fibers, as measured...

Hair luster is one of the most important parameters of visual appearance perceived by consumers. Current luster formulae (TRI, Reich-Robbins, ...) are optimized for goniophotometric measurements. They are based on a mathematical decomposition of reflected light into specular and diffused light and the meaurement of the shine peak width on the fitted angular distributions. In this expose, we are...

Aveh archaeological site, which has prepared the necessary background for the archaeological studiesafter having been identified and registered, is located in Saveh Plain, and it is one of the less-known sitesin the Iranian Central Plateau. The chronological sequence of this site extends from prehistoric periodstill Timurid time. It is worth mentioning that here, except for the Islamic settleme...

A new aperiodic tile set containing only 13 tiles over 5 colors is presented. Its construction is based on a technique recently developed by J. Kari. The tilings simulate behavior of sequential machines that multiply real numbers in balanced representations by real constants.

This paper describes a series of visual search experiments for targets defined by their hinocular characteristics. In searches for targets defined by binocular rivalry among fused distractors, or vice versa, the rivalrous items do not "pop out" (reaction time [RT] increases with number of distractors). Binocular luster, a variety of rivalry, is an exception. Luster, an important property of vis...

Assessing the quality of pearls involves the use of various tools and methods, which are mainly visual and often quite subjective. Pearls are normally classified by origin and are then graded by luster, nacre thickness, surface quality, size, color and shape. The aim of this study was to investigate the capacity of Artificial Neural Networks (ANNs) to classify and estimate the quality of 27 dif...

Thanks to a careful study of elementary properties of two-bytwo substitution systems, we give a complete self-contained elementary construction of an aperiodic tile set and sketch how to use this tile set to elementary prove the undecidability of the classical Domino Problem.
