The Lagrange-Galerkin Spectral Element Method on Unstructured Quadrilateral Grids

The purpose of this paper is to introduce a new method formed by fusing the Lagrange? Galerkin and spectral element methods. The Lagrange? Galerkin method traces the characteristic curves of the solution and, consequently, is very well suited for resolving the nonlinearities introduced by the advection operator of the fluid dynamics equations. Spectral element methods are essentially higher order finite element methods that exhibit spectral (exponential) convergence, provided that the solution is a smooth function. By combining these two methods, a numerical scheme can be constructed that resolves, with extremely high precision, the nonlinearities of the advection terms and the smooth regions of the flow generated by the diffusion terms. This paper describes the construction of the Lagrange? Galerkin spectral element method which permits the use of any grid type including unstructured grids. The only restriction at the moment is that the grid elements be quadrilaterals. The stability analysis of both methods demonstrates why these two methods are so powerful individually and how their fusion leads to an improved scheme. The Lagrange? Galerkin spectral element method is validated using the 1D and 2D advection and advection? diffusion equations. The results of the stability analysis and the numerical experiments demonstrate the utility of such an approach.
Methodology of modeling hybrid controller for university management in synergy with industry

Management of university is a very complex task in modern society. Universities are 'producing' experts for different industrial sectors. New profiles of experts required from industry are rising almost every day. Accordingly, it is required from the university to change study programs and to introduce new disciplines of science in its curriculum. The paper presents the IDEF0 methodology for modeling hybrid controller for university management. The university, which has three groups of activities (teaching, research and management of overall business), falls into the category of complex systems, modeled by the methods and techniques from the theory of complex systems. For the hybrid controller with feedback (composed of the hybrid controller with lower levels of management), the object of management is university's integrated system in synergy with its own educational-business environment.
Paradox, Promise and Public Pedagogy: Implications of the Federal Government’s Digital Education Revolution

The use of digital technology in the classroom is a significant issue for teachers as they are under increasing pressure to teach in technologically mediated ways. This 'digital turn' in education has culminated in the Australian federal government's Digital Education Revolution, which represents a multi-billion dollar commitment to putting computers in schools and the implementation of technological pedagogical practice. This paper focuses on the confluence between globalised economic process, the Digital Education Revolution, and the discourse of the digital native; and describes the way in which students' use of digital technologies is identity forming. I examine the Digital Education Revolution policy and related discourse in order to sketch out some of the educational implications. Drawing upon Giroux's (2004) notion of 'public pedagogy' I argue that using digital technologies could potentially open up an educative space to allow students to author their own digital identity. While the Digital Education Revolution is a product of the influence of globalisation upon education, it, nonetheless, contains contradictory prohibitions and possibilities that can be utilised to take the use of digital technology beyond that of preparing students for work in a globalised information economy.
A Comparative Study of Open-Domain and Specific-Domain Word Sense Disambiguation Based on Quranic Information Retrieval

Information retrieval is the process of analysing typed query as well as to retrieve relevant document according to the user query. Several issues can significantly affect the effectiveness of information retrieval. One of the common issue is the ambiguity lies on the words where a single word could yield several meanings. The process of identifying the exact sense of word is called Word Sense Disambiguation (WSD). Quran is the holly book for nearly 1.5 billion Muslims around the world. In particularly, Quran contains numerous words that can undergone multiple meanings. Therefore, there is a vital demand to apply WSD approach on Quran, in order, to improve the information retrieval. Several WSD approaches have been proposed for Quranic retrieval. However, these approaches are divided into two main categories; open-domain WSD approach and specific-domain WSD approach. Open-domain WSD is an approach that utilizes an open-domain dictionary such as WordNet, that is exploited to provide the exact sense. Whereas, domain-specific WSD approach aims to utilize a restricted training data that contain specific senses related to the domain of Quran. Hence, this study aims to establish a comparative study to investigate the two WSD categories including domain-specific and open-domain. For the domain-specific approach, a predefined example data has been collected to train Yarwosky algorithm which is a semisupervised machine learning technique. Then, based on the training, such algorithm can classify the exact sense for the words. In contrast, WordNet which is an open-domain dictionary has been used in this study with semantic distances, in order, to identify the similarity between the query word and the results of WordNet’s concepts. That dataset that has been used in this study is a Quranic translation. The experimental results have shown the mixed superiority of Yarwosky algorithm and WordNet WSD approach.
The Test of Word Reading Efficiency (TOWRE) used in an Australian context

Abstract Australian results on PISA 2000 (Program for International Student Assessment; OECD, 2002) show polarised reading achievement, with large proportions of strong readers (>40%) but also large proportions of weak readers (>30%). From the results it would seem that current instruction meets many readers’ needs, but not those of this lower third. With reading accuracy not emphasised in Australian reading instruction in recent decades, reading accuracy difficulties may underlie this weak achievement. This paper discusses issues that underlie the optimising of reading instruction in Australia, the importance of applied research at school level in resolving these issues, and the merits of use of rigorous reading accuracy tests in this research. The Test of Word Reading Efficiency (TOWRE) is discussed as a potential test for gathering such evidence and data, and the findings from testing of 1200 students in one Queensland region are discussed.
Galaxy And Mass Assembly (GAMA): the environments of high- and low- excitation radio galaxies

We study the environments of low- and high- excitation radio galaxies (LERGs and HERGs respectively) in the redshift range $0.01 < z < 0.4$, using a sample of 399 radio galaxies and environmental measurements from the Galaxy And Mass Assembly (GAMA) survey. In our analysis we use the fifth nearest neighbour density ($\Sigma_{5}$) and the GAMA galaxy groups catalogue (G3Cv6) and construct control samples of galaxies matched in {\update stellar mass and colour} to the radio-detected sample. We find that LERGs and HERGs exist in different environments and that this difference is dependent on radio luminosity. High-luminosity LERGs ($L_{\rm NVSS} \gtrsim 10^{24}$ W Hz$^{-1}$) lie in much denser environments than a matched radio-quiet control sample (about three times as dense, as measured by $\Sigma_{5}$), and are more likely to be members of galaxy groups ($82^{+5}_{-7}$ percent of LERGs are in GAMA groups, compared to $58^{+3}_{-3}$ percent of the control sample). In contrast, the environments of the HERGs and lower luminosity LERGs are indistinguishable from that of a matched control sample. Our results imply that high-luminosity LERGs lie in more massive haloes than non-radio galaxies of similar stellar mass and colour, in agreement with earlier studies (Wake et al. 2008; Donoso et al. 2010). When we control for the preference of LERGs to be found in groups, both high- and low- luminosity LERGs are found in higher-mass haloes ($\sim 0.2$ dex; at least 97 percent significant) than the non-radio control sample.
Are we in a bubble? A simple time-series-based diagnostic

Time series with bubble-like patterns display an unbalance between growth and acceleration, in the sense that growth in the upswing is “too fast” and then there is a collapse. In fact, such time series show periods where both the first differences (1-L) and the second differences (1-L)2 of the data are positive-valued, after which period there is a collapse. For a time series without such bubbles, it can be shown that 1-L2 differenced data should be stable. A simple test based on one-step-ahead forecast errors can now be used to timely monitor whether a series experiences a bubble and also whether a collapse is near. Illustration on simulated data and on two housing prices and the Nikkei index illustrates the practical relevance of the new diagnostic. Monte Carlo simulations indicate that the empirical power of the test is high.
Radiation effects in supported nanoparticles

Nanotechnology applications are entering the market in increasing numbers, nanoparticles being among the main classes of materials used. Particles can be used, e.g., for catalysing chemical reactions, such as is done in car exhaust catalysts today. They can also modify the optical and electronic properties of materials or be used as building blocks for thin film coatings on a variety of surfaces. To develop materials for specific applications, an intricate control of the particle properties, structure, size and shape is required. All these depend on a multitude of factors from methods of synthesis and deposition to post-processing. This thesis addresses the control of nanoparticle structure by lowenergy cluster beam deposition and post-synthesis ion irradiation. Cluster deposition in high vacuum offers a method for obtaining precisely controlled clusterassembled materials with minimal contamination. Due to the clusters’ small size, however, the cluster-surface interaction may drastically change the cluster properties on deposition. In this thesis, the deposition process of metal and alloy clusters on metallic surfaces is modelled using molecular dynamics simulations, and the mechanisms influencing cluster structure are identified. Two mechanisms, mechanical melting upon deposition and thermally activated dislocation motion, are shown to determine whether a deposited cluster will align epitaxially with its support. The semiconductor industry has used ion irradiation as a tool to modify material properties for decades. Irradiation can be used for doping, patterning surfaces, and inducing chemical ordering in alloys, just to give a few examples. The irradiation response of nanoparticles has, however, remained an almost uncharted territory. Although irradiation effects in nanoparticles embedded inside solid matrices have been studied, almost no work has been done on supported particles. In this thesis, the response of supported nanoparticles is studied systematically for heavy and light ion irradiation. The processes leading to damage production are identified and models are developed for both types of irradiation. In recent experiments, helium irradiation has been shown to induce a phase transformation from multiply twinned to single-crystalline nanoparticles in bimetallic alloys, but the nature of the transition has remained unknown. The alloys for which the effect has been observed are CuAu and FePt. It is
Metadata of the chapter that will be visualized in SpringerLink

This study focuses on how knowledge sharing across boundaries of merging entities during an information system (IS) implementation project in a shared services center (SSC) context affects the resulting system functionality. Although the literature stresses the growing adoption of the SSC as an outsourcing model, there is a lack of studies that examine shared services as a dynamic process of knowledge sharing across the organizational boundaries. We draw on a sociomaterial practice perspective and on the theory of workarounds to analyze an IS implementation project in a healthcare organization resulting from a merger of previously independent hospitals. The results suggest that new technology can be enacted in different ways as it links up with practices of different communities of users. We propose a multilevel process model that indicates at the end of the project a resulting mix of formal and informal (workarounds) practices that emerged from a dialectic process of resistance to, and negotiation of, the IS configuration during its implementation.
ANTIOXIDANT AND ANTIBACTERIAL ACTIVITIES OF SELECTED ARMENIAN MEDICINAL PLANTS

The antioxidant potentials of ethanolic and aqueous extracts of Hypericum perforatum, Ocimum basilicum, Laurus nobilis leaves were evaluated by 2, 2-diphenyl-l-picrylhydrazyl radical (DPPH) assay. Simultaneously total flavonoids content and antibacterial potential of all the tested extract was also monitored. The highest radical scavenging capacity (RSC) was reported in ethanolic extract of H. perforatum leaves while the lowest RSC was reported in the aqueous extract of L. nobilis. The ethanolic extracts of L. nobilis posses more DPPH radical scavenging action, than their aqueous extracts. Ethanolic and aqueous extracts of H. perforatum shows significant antioxidant activity, it is near to inhibition capacities while ethanolic extract of O. basilicum leaf has exhibited small activity as compared with its aqueous extract. RSC of ethanolic extracts can correlates with flavonoids content. The antiradical activity of ethanolic and aqueous extracts of L.nobilis leaf can also correlate with total flavonoids content, while such type of correlation was not reported in the case of H. perforatum and O. basilicum leaves extracts. RSC of tested extracts can be ranged in the following way: quercetin > rutin > eth. H. perforatum > aq. H. perforatum > aq. O. basilicum > eth L.nobilis > eth. O. basilicum > aq. L.nobilis. All the ethanolic extracts express more antibacterial activity than aqueous extracts.
Stationary probability vectors of higher-order two-dimensional transition probability tensors

In this paper we investigate stationary probability vectors of higher-order two-dimensional symmetric transition probability tensors. We show that there are two special symmetric transition probability tensors of order $m$ dimension 2, which have and only have two stationary probability vectors; and any other symmetric transition probability tensor of order $m$ dimension 2 has a unique stationary probability vector. As a byproduct, we obtain that any symmetric transition probability tensor of order $m$ dimension 2 has a unique positive stationary probability vector; and that any symmetric irreducible transition probability tensor of order $m$ dimension 2 has a unique stationary probability vector.
Search for gas accretion imprints in voids – I. Sample selection and results for NGC 428

We present the first results of a project aimed at searching for gas accretion events and interactions between late-type galaxies in the void environment. The project is based on long-slit spectroscopic and scanning Fabry-Perot interferometer observations performed with the SCORPIO and SCORPIO-2 multimode instruments at the Russian 6-m telescope, as well as archival multiwavelength photometric data. In the first paper of the series we describe the project and present a sample of 18 void galaxies with oxygen abundances that fall below the reference `metallicity-luminosity' relation, or with possible signs of recent external accretion in their optical morphology. To demonstrate our approach, we considered the brightest sample galaxy NGC 428, a late-type barred spiral with several morphological peculiarities. We analysed the radial metallicity distribution, the ionized gas line-of-sight velocity and velocity dispersion maps together with WISE and SDSS images. Despite its very perturbed morphology, the velocity field of ionized gas in NGC 428 is well described by pure circular rotation in a thin flat disc with streaming motions in the central bar. We also found some local non-circular gas motions clearly related to stellar feedback processes. At the same time, we revealed a circumnuclear inclined disc in NGC 428 and a region with significant residual velocities that could be considered as a result of a recent (<0.5 Gyr) accretion event. The observed oxygen abundance gradient does not contradict this conclusion.
Code of Corporate Governance as a Catalyst to Companies' Performances: A Review of Malaysian Experience

This study aims to highlight whether the implementation of Malaysian Code of Corporate Governance in 2000 and the revise version in 2007 triggers a favourable impact to Malaysian Bourse listed companies’ performances. This study sets apart from prior studies by providing evidence on value relevance of ERM and corporate governance compliance using the Malaysian Code of Corporate Governance (MCCG) as a proxy for ERM practices. This study uses a standard and reliable accounting variables with two-tailed Wilcoxon signed rank test methods to provide a justifiable research methodology. It is found that test result to be in tandem with prior studies, nonetheless, is also found that both MCCGs fail to produce a lasting mechanism in enhancing companies’ performances.
Age, growth, and reproduction of leatherside chub ( Gila copei )

The leatherside chub (Gila copei) is a small cyprinid native to eastern and southern areas of the Bonneville Basin of Utah, Idaho, and Wyoming, to Wood River, Idaho, and to regions of the Snake River, Idaho and Wyoming, above Shoshone Falls (Baxter and Simon 1970, Simpson and Wallace 1982, Sigler and Sigler 1987). Gila copei is currently listed as a candidate for federal protection under the Endangered Species Act. Conservation efforts for G. copei would benefit from accurate life history data, yet the life history of G. copei is not well known. This species was thought to live less than five years (Sigler and Sigler 1987). Based on bright coloration of males and abdominal distension in females, Sigler and Miller (1963) concluded G. copei spawns between June and August. Using similar coloration criteria on males from Sulphur Creek, WY, Baxter and Simon (1970) suggested breeding occurred in late summer; Simon (1951) found females distended with eggs in early August. Other than these few observations, no data on age, growth, or reproduction are available. We present data on age, growth, and reproduction of leatherside chub from central Utah; these data were generated as a first step to understanding and protecting this potentially threatened, endemic fish species.

Using Social Media to Support the Learning Needs of Future IS Security Professionals.

The emergence of social media has forced educators to think differently about the way learning occurs. Students and practitioners alike are using new technologies to connect with peers/colleagues, share ideas, resources and experiences for extracurricular activities. The social business gaming platform considered in this study leverages the social networking concept (an activity that all students actively participate in) in an academic environment. The primary objective of this technology is to foster a sense of ‘thinking outside the box’ and analytical ability through a medium that is widely accepted by students and graduates who have entered the workplace. Both the environment and problems are developed to adapt to suit any academic course from conducting research to proposing business solutions. This study was undertaken in order to develop information systems security (ISS) skillsets through the creation and facilitation of social business gaming, which allowed students to measure their performances of understanding as part of their on-going learning. The online business game required students to apply what they have learned to problem situations and to further develop their understanding of ISS topics. The problems posed required that the learners had to prove that they understood the material being taught in the traditional lecture and could apply what they had learned in an online environment. The on-going assessment component of the gaming network was used not just as an assessment for grades but also as a learning tool. This research focuses on a group of final year undergraduate students completing Bachelor of Science in Information Systems (IS). The online social game was utilised as part of the continual assessment process to evaluate group interaction, role-playing, competition and learning in an ISS assignment.
Task Group : 3 D Scanning for Clothing Fit and Logistics

Military organizations require accurate information on the relationship between body size and shape to ensure proper fit of clothing and personal equipment. From an operational perspective, proper fit is essential for soldier clothing and equipment ensembles to function as designed, allowing optimal mobility, comfort and protection from environmental and ballistic threats. Meeting these requirements is challenging, as operational uniforms and ceremonial wear must be provided to all military members. Custom tailoring is provided for individuals of extreme body size, but this practise is expensive and undesirable. Additionally, secular changes in body size, and increasing ethnic diversity and presence of women in operational trades, including combat arms, has presented a challenge to military departments responsible for clothing specification, procurement and issuing. In response, the North Atlantic Treaty Organization Science and Technology Organization (NATO STO) has recognized the potential of 3D body scanning as a tool to rapidly acquire 3D anthropometry and body shape data to support clothing design and issuing. This has led to the establishment of NATO Research Task Group (RTG) HFM-266: 3D scanning for clothing fit and logistics. Currently, this Task Group is comprised of 9 member nations and one ally. The outcomes of this Task Group will serve to provide a better understating of the application of 3D body scanning technologies for military clothing and equipment application and inform the development of clothing sizing standards across NATO countries.
