Determination of Drop-Impact Resistance of Plastic Bottles using Computer Aided Engineering

ASTM D2463 discusses the standard test method for drop impact resistance of blow-molded thermoplastic containers using procedures to determine the mean failure height and the standard deviation of the distribution. Unfortunately, costly prototypes have to be created before the drop impact test can be conducted. The MSC Dytran program was used with finite element simulation of the drop impact test of plastic bottles to determine the failure height for polyethylene terephthalate (PET) and high density polyethylene (HDPE) bottles. The finite element results were verified using experimental results obtained using the test method prescribed in ASTM D2463. It was found that the finite element simulation obtained accurate results. The failure heights for the PET and HDPE bottles were 4.53 ± 0.41 m and 4.65 ± 0.81 m, respectively. The errors in the failure height obtained from the FE simulation were less than 9.27% for the PET bottle and 5.59% for the HDPE bottle.
Directionality and Resultativity: The Cross-linguistic Correlation Revisited

Recent approaches to the cross-linguistic variation in the expressions of directed motion assume a tight correlation between adjectival resultative and directed motion constructions (e.g., Beck and Snyder 2001, Mateu and Rigau 2001; 2002, McIntyre 2004, Beavers et al. 2004). Beck and Snyder (2001), in particular, argue that languages that allow adjectival resultatives also allow directed motion with goal PP (or telic Path PP) based on the compounding parameter proposed by Snyder (1995; 2001). This paper, however, shows that such ‘macro’-parametric approaches to the cross-linguistic variation (in directed motion) fail when individual languages are investigated in detail. Based on Korean, Japanese, Hebrew, Czech, and Indonesian, I show that there is no necessary correlation between directed motion (i.e., goal PP) constructions and the availability of resultative phrases, and that the previous parameter approaches face challenges in explaining the facts drawn from these languages. I further show that the variation in directed motion is better explained by careful examination of individual adpositions that differ from one language (e.g., English) to another (e.g., Korean).
Graph Processing : Main Concepts and Systems

The development of new processing and storage facilities leads to an increase in the size of the problems to be solved. One of such problems is graph processing, which characterized by their non-determinism and an irregular memory access pattern, that greatly complicates its development and debugging. In this paper, we describe the basic concepts that make it possible to simplify the development of graph algorithms and its porting to various computer architectures. In addition, a description of the most well-known graph processing systems that implement these concepts is given.
Small signal modulation characteristics of red-emitting (λ = 610 nm) III-nitride nanowire array lasers on (001) silicon

The small signal modulation characteristics of an InGaN/GaN nanowire array edge- emitting laser on (001) silicon are reported. The emission wavelength is 610 nm. Lattice matched InAlN cladding layers were incorporated in the laser heterostructure for better mode confinement. The suitability of the nanowire lasers for use in plastic fiber communication systems with direct modulation is demonstrated through their modulation bandwidth of f-3dB,max = 3.1 GHz, very low values of chirp (0.8 A) and α-parameter, and large differential gain (3.1 × 10−17 cm2).
Epileptic State Detection: Pre-ictal, Inter-ictal, Ictal

Epileptic seizure detection and prediction from electroencephalography (EEG) is a vital area of research. In this study, Second-Order Difference Plot (SODP) is used to extract features based on consecutive difference of time domain values from three states of EEG (pre-ictal, ictal and inter-ictal), and Multi-Layer Neural Network classifier is used to classify these three classes. The proposed technique is tested on a publicly available EEG database and classified with Naive Bayes and k -nearest neighbor classifiers. As a result, it is shown that overall accuracy of 98.70% can be achieved by using the proposed system with Neural Network classifier.
An Analysis of Herding in the Korean Stock Market Using Network Theory

We investigate whether herd behavior in the equity market is led by ‘core’ stocks or by ‘peripheral’ stocks connected to core stocks, which we identify with a technique from network theory. Using non-securities stocks listed in the Korea Exchange from January 2005 to December 2015, we find strong evidence of herding in the Korean stock market, as in previous studies on herding. Herding arises only when the market is in stress: during bear states, core stocks herd toward the market portfolio and peripheral stocks herd toward core stocks in their clusters. During bull markets, however, adverse herding arises mainly driven by securities stocks, and thus cross-sectional dispersion in returns increases. Core stocks are not necessarily the stocks whose market values are large but instead are mid-sized stocks.
Mixed Integer Nonlinear Programming Model for Positioning a New Product in a Multiattribute Space with Risk

This is a marketing problem faced by a firm which wishes to position a new brand product in an existing product class. It is natural that an individual choice for his/her most preferred products are influenced essentially by the perceptions and values of the products (e.g. the design of the product). Individuals usually differ in their choice of an object out of an existing set, and they would also differ if asked to specify an ideal object. Due to these differences, the aim of the problem considered here is to optimally design a new product in order to attract the largest number of consumers. This paper addresses a mixed integer nonlinear programming model to formulate the positioning problem. A direct search approach is proposed to solve the model. A computational experience is presented.
Pharmacological and Antagonistic Potentials of Mikania micrantha

The antimicrobial, chemical and allelopathical properties of invasive alien weed Mikania micrantha Kunth ex H.B. K were analyzed. The extraction was performed in different solvents by soxhlet extraction technique. Some bacteria ( Acinetobacter sp. and Bacillus subtilis ) were found to be highly inhibited, whereas the extract was found effective against Fusarium species (F. eridiforme) among the fungi. Of all the solvents used for extraction, methanolic hot extract showed good antimicrobial properties against tested pathogenic strains. The preliminary qualitative phytochemical assay divulged the presence of glycosides and quinones in the test plant. Germination rate was higher for all crops with control treatment. The germination rate decreased with the increase in the extract concentration and was found to be lowest at 5% concentration of extract. Generally, the radicle length of all bioassayed species decreased with increasing concentrations of Mikania, with Barley and Paddy being the most susceptible to the plant extract at full strength. The broad spectrum of activity of the extract indicated possibilities for wide use of M. micrantha for controlling the human pathogenic bacteria and phytopathogenic fungus that have been widely destroying crops.

COUPLING BETWEEN BACTERIOPLANKTON SPECIES COMPOSITION, POPULATION DYNAMICS, AND ORGANIC MATTER DEGRADATION

To study the effect of substrate addition on short term bacterial population dynamics and species composition in seawater, mesocosms were maintained with water collected off Scripps Pier (La Jolla, California, USA). Protein enrichment (BSA) triggered a dynamic response from the microbial food web, whereas enrichment with starch had no effect. In the protein enriched mesocosm the number of both nucleoid-containing cells and metabolically active cells increased by 3.0 x 10(5) cells ml(-1) from Day 1 to Day 4. In the same time period the density of a set of 31 phylogenetically different bacteria (alpha- and gamma-Proteobacteria as well as Flexibacter-Cytophaga-Bacteroides) increased by 3.5 x 10(5) cells ml(-1). The abundance of these isolated bacteria accounted for up to 89 % of the nucleoid-containing cells, and up to 22 % of the total counts. Increased enzyme activities, most notably protease, were found concomitant with a change in bacterial species composition over 3 d. This short term succession was possible due to rapid net growth rates of single bacterial species in the mesocosm (0.48 to 1.6 d(-1)), which was up to 5 times higher than the community turnover calculated from bacterial production and total counts. These results should provide support for studies of actual bacterial population dynamics on the species level and its role in the degradation of organic matter in the aquatic environment.
Islamic Banking and Performance in the Asean Banking Industry: A Topsis Approach with Probabilistic Weights

This paper uses an integrated two-stage approach to assess the performance of 88 ASEAN (Association of Southeast Asian Nations) banks from 2010-2013. The relative importance of different financial ratios that emulate the CAMELS rating is collected using the expert opinions of 88 ASEAN bank managers with the help of a structured questionnaire. The computation of empirical joint probabilities is used first to derive weights for a number of criteria related to Capital adequacy, Asset quality, Management quality, Earnings, Liquidity, and Sensitivity to market risk. In the second stage, these weights are used as TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) inputs to assess the relative efficiency of ASEAN banks. The results reveal the prominent role of Islamic principles in banking efficiency. More specifically, these beneficial results are found when banks are private. We then use our results to develop policy recommendations.
Process design of ultrasonic spray pyrolysis synthesis of Ru/TiO 2

The use of ultrasonic spray pyrolysis for the synthesis of nanostructured Ru/TiO 2 particles from an organic metal salt-solution was shown a completely new approach, because this complex catalytic system comprising both metal support and active mass were obtained in one single step contrary to conventional procedures. Products are predicted by thermochemical analysis using Software FactSage under different atmosphere. XRPD, SEM, FIB, EDS analyses were used in order to analyse morphological characteristic of particles. Formation of core and shell structure was investigated.
Survey Results and an Android App to Support Open Lesson Plans in Edu-AREA

This paper introduces an open view to lesson plans focused on primary and secondary teachers. Open Lesson Plans are proposed as a special kind of Open Educational Resources. This involves the educational contents they are built on, of course. In addition, we extend the open view taking into account their development during educational use: from creation, through the observation of classroom use, to the reflections when finished. The paper introduces the results of a survey conducted among Galician teachers based on this view. It also describes functionalities available in an Android App to support this open view in the Edu-AREA platform.
Recent expansion of the slipper limpet population (Crepidula fornicata) in the Bay of Mont-Saint-Michel (Western Channel, France)

A population of the invasive slipper limpet (Crepidula fornicata) has been spreading in the Bay of Mont- Saint-Michel (Western English Channel) for 40 years. Sidescan sonar, underwater video and quantitative sampling were conducted in 1996 and 2004 to document the widening geographic spread of the species over the bay. The limpet population grew by 50% during this period, to reach a fresh biomass of about 150 000 t. This local study analyses causes and effects of the spread and provides a typical example of the limpet spreading process. This population increase has significant effects on the environment in the most densely colonized area (modification to the sediment and biodiversity), leading to the emergence of a new benthic community. Anthropic dredging activities are among the causative factors of the spread but are also adversely affected by the invasion.
Nanoscale Pinning in the LRE-123 System - the Way to Applications up to Liquid Oxygen Temperature and High Magnetic Fields

The discovery of superconductivity in oxides (Bednorz, et al., 1986), especially in the system of YBa2Cu3Oy “Y-123” (Wu et al., 1987), having a transition temperature well above boiling point of liquid nitrogen and capable of carrying critical current densities at a level necessary for practical use, moreover in rather high magnetic fields, placed cuprate composites into center of the present material physics and technology. Liquid nitrogen cooling has promised construction of cryogenic systems greatly simplified, more realistic and economical in operation. Note that not only the critical temperatures of the new superconductors have been much higher than those of the conventional materials. The upper critical field of the order of 100 T has been estimated and also measured, making from these materials ideal candidates for high field applications (Welp et al., 1989). On the other hand, it has also been found that high-Tc materials in a polycrystalline form carry only low critical current densities, due to grain boundary weak links and crystal anisotropy (Cava et al., 1987). Attempts to improve the critical current density of the Y-123 material by texturing substrates and identifying coupling mechanisms at interface started immediately worldwide (Jin et al., 1988; Babcock et al., 1990). U.S. Pat. No. 5,061,682, issued to Aksay et al., 1991 disclosed a process for preparing conductive and superconductive ceramics composed of Y2BaCuO5, YBa2Cu3O7, and YBa2Cu4O8. The most successful process at present is melttexturing, which controls to a high degree lattice orientation of the crystalline material. In this way the superconducting phase (YBa2Cu3Ox) is formed by a peritectic reaction of Y2BaCuO5 (211) with a liquid phase. The growth process of the superconducting phase is accelerated by means of finely and homogeneously dispersed 211 phase in the liquid phase; at the same time, however, the 211 phase serves as a pinning medium dispersed in the superconducting phase. During the following slow cooling nucleation often occurs. This secondary nucleation forms parasitic grains that consume the material intended for the growth of superconducting grains. In this way high-angle grain boundaries are created that
Local Gray Code Pattern ( LGCP ) : A Robust Feature Descriptor for Facial Expression Recognition

This paper presents a new local facial feature descriptor, Local Gray Code Pattern (LGCP), for facial expression recognition in contrast to widely adopted Local Binary pattern. Local Gray Code Pattern (LGCP) characterizes both the texture and contrast information of facial components. The LGCP descriptor is obtained using local gray color intensity differences from a local 3x3 pixels area weighted by their corresponding TF (term frequency). I have used extended Cohn-Kanade expression (CK+) dataset and Japanese Female Facial Expression (JAFFE) dataset with a Multiclass Support Vector Machine (LIBSVM) to evaluate proposed method. The proposed method is performed on six and seven basic expression classes in both person dependent and independent environment. According to extensive experimental results with prototypic expressions on static images, proposed method has achieved the highest recognition rate, as compared to other existing appearance-based feature descriptors LPQ, LBP, LBPU2, LBPRI, and LBPRIU2.
Influence of tides and gravity waves on layering processes in the polar summer mesopause region

Polar Mesosphere Summer Echoes (PMSE) have been studied at Andenes (69° N, 16° E), Norway, using VHF radar observations since 1994. One remarkable feature of these observations is the fact that {during 50% of the time,} the radar echoes occur in the form of two or more distinct layers. In the case of multiple PMSE layers, statistical analysis shows that the lower layer occurs at a mean height of ~83.4 km, which is almost identical to the mean height of noctilucent clouds (NLC) derived from observation with the ALOMAR Rayleigh/Mie/Raman lidar at the same site. To investigate the layering processes microphysical model simulations under the influence of tidal and gravity waves were performed. In the presence of long period gravity waves, these model investigations predict an enhanced formation of multiple PMSE layer structures, where the lower layer is a consequence of the occurrence of the largest particles at the bottom of the ice cloud. This explains the coincidence of the lowermost PMSE layers and NLC. During periods with enhanced amplitudes of the semidiurnal tide, the observed NLC and PMSE show pronounced tidal structures comparable to the results of corresponding microphysical simulations. At periods with short period gravity waves there is a tendency for a decreasing occurrence of NLC and for variable weak PMSE structures.
Experimental Study of Plasma Under-liquid Electrolysis in Hydrogen Generation

The application and characteristics of relatively big volume plasma produced with cathodic glow discharges taking place across a gaseous envelope over the cathode which was dipped into electrolyte in hydrogen generation were studied. A critical investigation of the influence of methanol concentration and voltage across the circuit on the composition and power consumption per cubic meter of cathode liberating gas was carried out. The course of plasma under-liquid electrolysis has the typical characteristics of glow discharge electrolysis. The cathode liberating gas was in substantial excess of the Faraday law value. When the voltage across the circuit was equal to 550 V, the volume of cathodic gas with sodium carbonate solution was equal to 16.97 times the Faraday law value. The study showed that methanol molecules are more active than water molecules. The methanol molecules were decomposed at the plasma−catholyte interface by the radicals coming out the plasma mantle. Energy consumption per cubic meter of cathodic gases (WV) decreased while methanol concentration of the electrolytes increased. When methanol concentration equaled 5% (ϕ), WV was 10.381×10 3 kJ/m 3 , less than the corresponding theoretic value of conventional water electrolysis method. The cathodic liberating gas was a mixture of hydrogen, carbon dioxide and carbon monoxide with over 95% hydrogen, if methanol concentration was more than 15% (ϕ). The present research work revealed an innovative application of glow discharge and a new highly efficient hydrogen generation method, which depleted less resource and energy than normal electrolysis and is environmentally friendly.
Thermoplastic Starch (TPS)‐Cellulosic Fibers Composites: Mechanical Properties and Water Vapor Barrier: A Review

Current research studies have been focusing on the procurement of environmentally friendly materials, with the aim of resolving the problems created by materials derived from petroleum. Starch is a promising biopolymer for producing biocomposite materials because it is renewable, completely biodegradable, and easily available at a low cost. Thermoplastic starch (TPS), by itself, exhibits poor mechanical properties such as low tensile strength and severe deformations, which limits its application in packaging or films. In addition, TPS presents high hygroscopicity. The use of reinforcing agents in the starch matrix is an effective means to overcome these drawbacks and several types of biodegradable reinforcements, such as cellulosic fibers, whiskers, and nanofibers, have been utilized to develop new and inexpensive starch biocomposites. This chapter provides the latest advances in green composite materials based on TPS and cellulose fibers and includes information on compositions, preparations, and the properties of “green” composite materials elaborated from TPS and cellulose fibers, with the focus on using undervalued natural resources.
Embolism resistance of conifer roots can be accurately measured with the flow-centrifuge method

Resistance to embolism of conifer branches has commonly been studied with the flow-centrifuge technique (Cavitron) to carry out routine measurements. The aim of this study was to test the accuracy of the Cavitron for measurements on conifer roots. Based on earlier findings, it was suggested that the application of the flow-centrifuge technique to roots may not be free from artefacts due to potential torus aspiration when the pressure gradient between the sample ends is high. Here, three different protocols were used to obtain vulnerability curves in Pinus pinaster and Pseudotsuga menziesii roots: no water pressure gradient, and low and high water pressure gradient. In addition water extraction curves were obtained to only estimate the water released from conduits by embolism. Water extraction curves showed no water release caused by embolism before -1.3 and -2.5 MPa for P. pinaster and P. menziesii, respectively. The results illustrated discrepancies between these protocols: roots measured with the high and low pressure gradient protocols appeared erroneously more vulnerable to embolism than roots measured with no pressure gradient. In addition, pit anatomical observations of roots showed non-punctured tori and a high flexibility of the margo, which may increase the risk of torus aspiration. All together these results suggest that the early loss of hydraulic conductivity observed for the low and high pressure gradient protocols was not due to embolism but rather to a torus aspiration artefact when the pressure gradient is too high. We conclude that the no pressure gradient protocol provides a suitable method and that high vulnerability to embolism reported in previous studies for conifer roots should be interpreted with caution in the light of our findings.
A wave propagation method for compressible multiphase flow on mapped grids

A simple interface-capturing approach to compressible homogeneous multiphase flow problems is developed for the Euler equations of gas dynamics with a stiffened gas equation of state on body-fitted mapped grids in general twoand three-dimensional geometries. The algorithm uses a generalized coordinate formulation of the equations that is derived to ensure the correct fluid mixing when approximating the equations numerically with material interfaces. A γ-based and a α-based model have been described that is an easy extension of the Cartesian coordinates counterpart devised previously by the author (K.-M. Shyue, An efficient shock-capturing algorithm for compressible multicomponent problems, J. Comput. Phys. 142 (1998) 208-242). A standard high-resolution wave propagation method is employed to solve the proposed multiphase models with the dimensional-splitting technique incorporated for an efficient implementation of the method to multidimensional problems. Several calculations are presented with an HLLC approximate Riemann solver that show accurate results obtained using the method without introducing any spurious oscillations in the pressure near the interfaces. This includes some validation tests for problems in two dimensions where our quadrilateral-grid results are in direct comparison with the ones obtained using a Cartesian grid embedded boundary method. Sample results for three-dimensional problems on hexahedral grids are shown also.
