Modeling of liquid flow in surface discontinuities

Polymer composite and metallic materials have found wide application in various industries such as aviation, rocket, car manufacturing, ship manufacturing, etc. Many design elements need permanent quality control. Ensuring high quality and reliability of products is impossible without effective nondestructive testing methods. One of these methods is penetrant testing using penetrating substances based on liquid penetration into defect cavities. In this paper, we propose a model of liquid flow to determine the rates of filling the defect cavities with various materials and, based on this, to choose optimal control modes

Experimental demonstration of extended depth-of-field f/1.2 visible High Definition camera with jointly optimized phase mask and real-time digital processing

Increasing the depth of field (DOF) of compact visible high resolution cameras while maintaining high imaging performance in the DOF range is crucial for such applications as night vision goggles or industrial inspection. In this paper, we present the end-to-end design and experimental validation of an extended depth-of-field visible High Definition camera with a very small f-number, combining a six-ring pyramidal phase mask in the aperture stop of the lens with a digital deconvolution. The phase mask and the deconvolution algorithm are jointly optimized during the design step so as to maximize the quality of the deconvolved image over the DOF range. The deconvolution processing is implemented in real-time on a Field-Programmable Gate Array and we show that it requires very low power consumption. By mean of MTF measurements and imaging experiments we experimentally characterize the performance of both cameras with and without phase mask and thereby demonstrate a significant increase in depth of field of a factor 2.5, as it was expected in the design step

Urban Built Environments of the Early 1st Millennium BCE: Results of the Tayinat Archaeological Project, 2004-2012

The archaeological site of Tell Tayinat in the province of Hatay in southern Turkey was the principal regional center in the Amuq Plain and North Orontes Valley during the Early Bronze and Iron Ages. This paper focuses on the latest known period of occupation at Tayinat, which during the Iron Age was the Syro-Anatolian city of Kunulua. In 2004, following a 67-year hiatus, the University of Toronto’s Tayinat Archaeological Project (TAP) resumed excavations at the site. Here we present the preliminary results of TAP’s investigations of the Iron Age II and III settlement, including the topography of the 1st millennium settlement, super- and sub-structural remains associated with Building II (a temple first discovered in the 1930s), a second, newly discovered temple (Building XVI), part of a large Assyrian-style courtyard building, and the remains of additional monumental architecture on the Iron Age citadel. The terminal phases of these structures date to the Iron Age III period, or the late 8th and 7th century occupation of Kunulua following the Assyrian conquest in 738 b.c.e., and collectively point to the transformation of Kunulua’s royal citadel into a Neo-Assyrian provincial administrative center, a pattern witnessed at contemporary sites elsewhere in southeastern Anatolia and northern Syria

Genetic diversity of Macaca fascicularis (Cercopithecidae) from Penang, Malaysia as inferred from mitochondrial control region segment

The genetic diversity of the long-tailed macaques (Macaca fascicularis) from Penang, Malaysia, including Jerejak Island and the mainland area of the state of Penang, Seberang Perai were examined using 1,042 bp control region (CR) segment of the mitochondrial DNA (mtDNA). Twenty haplotypes were described with a single haplotype sharing between the mainland and the island which suggests that it is a remnant of the genetic makeup from the mainland. Compared to previous studies based on the CR, all the Penang haplotypes are newly described with none shared with the other regional populations of M. fascicularis. A single deletion mutation unique to the Penang samples (Groups I and II) could be a good indicator for the conservation of the genetic uniqueness and possibly should be managed as a management unit (MU). A summarised phylogenetic tree (NJ, MP, ML and Bayesian) supports the monophyletic clustering of the M. fascicularis as described in previous studies. The topology separates the Penang haplotypes into three major groups, which generally corresponds to their geographical distribution. We also noted that the Penang haplotypes are of the continental lineage which separated from the insular lineage at around 1.04 mya. Finally, we showed that the CR of the mtDNA is powerful and suitable for the quantification of intraspecific diversity in M. fascicularis
