Application of Mathematical Model to Assess Sediment Movement Pattern along Nearshore Coastal Water

Movement of sediment load and its pattern of transportation along nearshore coastal water is a very important phenomenon to be assessed for different sector of coastal Engineering. To develop and understand the physical processes responsible for shaping the ongoing evolution of the coast and to develop the management strategies to deal the impact of human activities on the coastal zone and as well as for adapting to the hazards associated with the people living on the coast, knowledge of the mechanism, processes and the pattern of sediment movement in the nearshore zone is of utmost importance. Nearshore zone is a very active area, where a series of dynamic processes occur in response to changing wave climates and sediment budgets. Nowadays mathematical modeling is an attractive alternative and becoming a very viable approach to study the sediment movement pattern with the advanced computational facilities and improved understanding on wave mechanics and sediment transport processes. It is very effective, reliable and also comfortable to study the pattern of sediment transportation including yield, distribution and management of sediment with the help of mathematical model. Validity of forecast in sediment transport depends on both mathematical modeling technique and boundary conditions.
Gender Variation and Transitions between Sexual Systems in Mercurialis annua (Euphorbiaceae)

Evolutionary transitions between hermaphroditism and dioecy have occurred numerous times in the land plants. We briefly review the factors thought to be responsible for these transitions, and we provide a synthesis of what has been learned from recent studies of the annual herb Mercurialis annua, in which dioecy (males and females), monoecy (functional hermaphrodites), and androdioecy (males and hermaphrodites) occur in different parts of its geographic range. Previous research on M. annua has revealed the importance of genome duplication and hybridization in the origin of much of the observed variation. Here we show, however, that spatial transitions in the sexual system also occur within the same ploidy level. In particular, we present an analysis, using flow cytometry data, of ploidy variation across a previously unstudied transition between hermaphroditism and androdioecy, in which we find that the sexual‐system transition is uncoupled from the shift in ploidy levels. We review recent research that shows that such transitions between sexual systems in M. annua are consistent with differential selection at the regional level for reproductive assurance during colonization. We also present new experimental data that highlight both the importance of the resource status of plants and that of their local mating context in regulating gender strategies and sex ratios. The studies reviewed and the new results presented emphasize the role that shifts in the ecological and genetic context of plant populations may play in causing transitions between sexual systems.
Psychometric Properties of the Measure of Adolescent Coping Strategies (MACS)

This paper presents the collective results of three independent studies in two countries, Australia and Iceland, aimed to develop a psychometrically sound adolescent coping scale, the Measure of Adolescent Coping Strategies (MACS). Study 1, relying on 3034 Australian and 6908 Icelandic adolescents, revealed five conceptually distinct first-order factors. Two second-order factors (dimensions) were derived: (a) adaptive coping encompassing stoicism/distraction, seeking social support, and self-care, and (b) maladaptive coping encompassing acting out and rumination. This factor structure was supported by multisample confirmatory factor analysis (MSCFA) across age, gender and national samples. Study 1 established evidence of discriminant validity. In Study 2, including 534 Australian adolescents, the factor structure was verified through confirmatory factor analysis (CFA). Studies 1 and 2 provided evidence of construct validity. Study 3, employing 118 Icelandic adolescents, established 16-week test-retest reliability and evidence of convergent validity. Therefore, the MACS is a short, reliable and valid scale to measure adolescent coping, thus enabling clinicians, researchers and educators to improve their practice when conducting research and guiding adolescents in developing effective coping methods.
A method of combining coherence-constrained sparse coding and dictionary learning for denoising

ABSTRACTWe have addressed the seismic data denoising problem, in which the noise is random and has an unknown spatiotemporally varying variance. In seismic data processing, random noise is often attenuated using transform-based methods. The success of these methods in denoising depends on the ability of the transform to efficiently describe the signal features in the data. Fixed transforms (e.g., wavelets, curvelets) do not adapt to the data and might fail to efficiently describe complex morphologies in the seismic data. Alternatively, dictionary learning methods adapt to the local morphology of the data and provide state-of-the-art denoising results. However, conventional denoising by dictionary learning requires a priori information on the noise variance, and it encounters difficulties when applied for denoising seismic data in which the noise variance is varying in space or time. We have developed a coherence-constrained dictionary learning (CDL) method for denoising that does not require any a priori .
Importance of the Corporate Reputation in B2B Context in Iran: An Empirical Study

Corporate reputation researches have largely focus on consumer market and attention has been given to the business market recently. The purpose of this paper is to develop an integrated model that indicates the influence of corporate reputation on customer loyalty in Business-to-Business (B2B) markets by implementing the model of Cretu and Brodie (2007) with additional concentration on personal relationship in B2B. To achieve this purpose, a structured questionnaire distributed among 80 executive managers who work in variety industries such as construction, mining and generator motor equipment in Iran. The results prove that corporate reputation has effect on loyalty but with less impact in compared to satisfaction; moreover the personal relation has no significant impact on loyalty.

Implications for experiential educators are discussed.
An alternative model for ultra-high pressure in the Svartberget Fe-Ti garnet-peridotite, Western Gneiss Region, Norway

Thepreviouslyreported''Fe-Titype''garnet-peridotiteislocatedinthenorthernpartofthewellknownultra-highpressure (UHP) area of the Western Gneiss Region (WGR) in Norway. Primary spinel stable up to only 2.0 GPa at 800 ! C coexists with Caledonian ultra-high pressure (4.0 GPa at 800 ! C) grt-cpx-opx-ol assemblages in the Svartberget garnet-peridotite. The body is cut byaconjugatesetofmetasomaticfracturesfilleddominantlywithdiamond-bearinggarnet-phlogopite-websterite (5.5GPaat800 ! C) and garnetite. Single zircon U-Pb dating suggests metamorphic growth of zircon in the garnetite at 397.2 " 1.2 Ma, either coinciding or predating an initial phase of leucosomes formation at 397-391 Ma. Field observations, major and trace elements, mineral- chemistry, polyphase inclusions including microdiamond, coupled with 87 Sr/ 86 Sr ratios in clinopyroxene and whole rock ranging from 0.73 to 0.74, suggest that the Svartberget garnet-peridotite was infiltrated by melts/fluids from the host-rock gneiss during the CaledonianUHPevent.PresentobservationsintheWGR documentaregionalmetamorphicgradientincreasingtowardstheNW,and structures in the field can account for the exhumation of the (U) HP rocks from # 2.5 to 3 GPa. Assuming lithostatic pressures the diamond-bearing Svartberget peridotite body must have come from a burial depth of more than 150 km. However, there is a lack of observable structures in the field to explain exhumation from extreme UHP conditions (5.5 GPa or more) to normal HP-UHP conditions (2.5-3 GPa), which are common pressures calculated from eclogites in western parts of the WGR. Because of the regional and mostly coherent metamorphic gradient across the WGR terrain, it is difficult to account for local extreme pressure excursions such as documented from within the Svartberget peridotite. We introduce here a conceptual model to explain the main features of the Svartberget body. During burial and heating, rocks surrounding the peridotite start to melt but surrounding non-molten rocks confine the space and pressure builds up. When pressure is high enough, conjugate brittle shear fractures develop in the peridotite. Melt (or supercritical fluid) that has the same pressure (5.5 GPa) as the surrounding gneiss can flow in as soon as fractures propagate into the peridotite. This supercritical fluid is now highly reactive and metasomatism takes place at UHP conditions along the fractures capturing micro inclusions of diamond while growing. Finally the lithosphere holding the overpressurised gneiss con- strained breaks duetoformationoflarge-scale fracturesinthe crustanddecompression meltingstarts.Modelling usingfinite-element method (FEM) shows that melting of the gneiss results in pressure variations when gneiss is ten to hundred times weaker than surroundings and peridotite enclave. These pressure variations can be up to several GPa and are qualitatively similar to observations in the field.
How Much DoWe Know about Rural-Urban Health Disparities: Lessons from Four Major Diseases in Virginia

Health disparities are abundantly recorded in literature, but is much less understood within a rural-urban context. In this paper, four major diseases in Virginia are studied: cancer, stroke, cardiovascular disease (heart disease) and chronic obstructive pulmonary disease (COPD). Separate count data regressions are estimated at regional level to provide a primary understanding of those factors. A simultaneous equations model with rural-urban specification are then estimated via seemingly unrelated regression (SUR) techniques to take account of possible causalities among these diseases as well as error correlations, which is followed by Blinder-Oaxaca decomposition of the disparity proportions explained by observed characteristics and unobserved mechanisms. The results suggest that regional-level factors are significantly correlated with health disparities between rural and urban areas. The unknown mechanisms behind these linkages are different between rural and urban areas, and explain an even larger proportion of these disparities.
Why Sustainable Design Should Be in Accordance with a Participatory Design Approach – The 1st phase of Sustainable Kampong Model: Margamulya Village, Mauk, Tangerang

Sustainability has been becoming an important issue in recent years in architecture and design. On the other hand the practice has also seen new approaches that emphasize active participation of stakeholders. This research thus tried to consider both of these approaches, as needs within each other and aimed to develop a schematic sustainable design model for built environment. Margamulya Village, Mauk, Tangerang is the case study, as this kampong (village) represents a traditional informal kampong with its disarray and unplanned development, while on the other hand it has already been touched by a certain NGO specialized in in providing decent housing. In this sense the research will use PAR (Participatory Action Research) as an umbrella for the research methodology, CBPR (Community-Based Participatory Research) as an approach and PD (Participatory Design) as the research tool. The research will be conducted in two stages: (a) the 1 st year focusing on developing a schematic design model for a more sustainable Margamulya Village, Mauk, Tangerang, and; (b) the 2 nd year focusing on developing a participatory model for the community everyday activities within their social, economic and cultural sphere. The research is currently in the 1 st phase.
An Efficient Adaptive Denoising Algorithm for Remote Sensing Images

Typically, after the capturing, imaging, and transferring processes have been accomplished, the digital images will contain a variety of noise, caused by both the equipment itself and by the complex working environment. Consequently, it is necessary to perform a de-noising process to facilitate the extraction of useful information. This paper presents a fast and efficient denoising algorithm, which combines the advantages of traditional median filters and weighted filter algorithms. In this algorithm, the noise in the figure is determined, and those results are applied to adaptively change the size of the window, while assigning different weights to the pixels in the filter window. The experimental results show that we can significantly remove almost all salt and pepper noise, while retaining full image textures, edges, and other minutiae.
Impact Test and Bioactivity Properties of Polycaprolactone (PCL) by Addition of Nano-Montmorillonite (MMT) and Hydroxyapatite (HA)

This report described the Impact Test result and Bioactivity Properties of biodegradable Polycaprolactone (PCL) blend with nano- Montmorillonite (MMT) and Hydroxyapatite (HA). The amount of nano-MMT is varies from 2 to 4 by weight % meanwhile the amount of HA is fixed to 10 by weight percentage (wt%). The addition of nano-MMT and HA filler is to tune and indirectly improve the mechanical and bioactive properties of PCL. The samples for these test are injected from injection molding machine. The Impact test are conducted using Charpy Method. From the analysis it is found that the toughness of PCL are decreased by the addition of these fillers. PCL/MMT composites gives a better result compare to PCL/MMT/HA composites. This is due to the HA characteristic which is brilttle and tends to reduce the ductile properties of the polymer. From the Simulated Body Fluis (SBF) result, formation of apatite layer at the surface of the composites is evidence of excellent bioactivity properties of HA. The enhance of bioactivity has been proved while incorporation of HA into PCL/MMT composite. SEM-EDX image showed the bulk formation of apatite layers on the composite surface with 10 wt% HA after 3 days immersed in SBF solution.
Preparation and induction for school principals

This article will examine different international approaches to leadership preparation and induction, linked to concepts of socialization and identity. Although leadership is widely understood to be the second most important factor influencing student outcomes, principal preparation is neglected in many countries. A teaching qualification and teaching experience are often considered to be sufficient attributes for new principals. The article will argue that being a principal is a different role from classroom teaching and requires specific preparation. This involves three phases of socialization. First, aspiring leaders require professional socialization, preparing to become a principal. Second, they need to change their identity, from teacher to principal – a process of personal socialization. Third, they need a period of organizational socialization, learning to lead in a specific school. The article will draw on international research and literature to consider the experience of new principals in different settings. It will also examine examples of preparation and induction in several settings to establish what works effectively and in what contexts. It will also consider the role of mentoring in successful principal preparation and induction, bearing in mind the need for induction to be an extended process, not a ‘one-off’ event. The article will conclude with a model for leadership preparation and induction, which could be applied in many places, subject to careful adaptation to fit the local culture and context.
Implementation of a one-lead ECG human identification system on a normal population

The electrocardiogram (ECG) is not only a very useful diagnostic tool for clinical purposes, but also is a potential new biometric tool for human identification. TheECG may be useful as a biometric in the future, since it can easily be combined with other biometrics to provide a liveness check with little additional cost. This research focused on short-term, resting, Lead-I ECG signals recorded from the palms. A total of 168 young college volunteers were investigated for identification as a predetermined group. Fifty persons were randomly selected from this ECG biometric database as the development dataset. Then, the identification algorithm developed from this group was tested on the entire database. In this research, two algorithms were evaluated for ECG identification during system development. The algorithms included template matching and distance classification methods. Signal averaging was applied to generate ECG databases and templates for reducing the noise recorded with palm ECG signals. When a single algorithm was applied to the development dataset, the identification rate (that is, rank one probability) was up to 98% (49 out of 50 persons). However, when the prescreening process was added to construct a combined system model, the identification rate increased to 100% accuracy on the development dataset. The combined model formed our ECG biometric system model based on results from the development dataset. The identification rate was 95.3% when the same combined system model was tested on the entire ECG biometric database. Key words: Biometrics, biometric liveness tests, electrocardiogram (ECG), ECG features, identification, template matching, distance classification
Protective Activity of Seolitae Chungkukjang Added with Green Tea against Cellular Oxidative Stress induced by AAPH

The protective activity of seolitae chungkukjang added with green tea against oxidative stress was investigated under the cellular systems using LLC-PK1 cells. The treatment of 2,2'-azobis(2-aminopropane) dihydrochloride (AAPH) showed increase in lipid peroxidation, and decrease in endogenous antioxidant enzymes activity and cell viability. However, the methanol extract of seolitae chungkukjang inhibited lipid peroxidation by 58.3%, and increased cell viability up to more than 60%. In addition, it enhanced superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities. Seolitae chungkukjang improved oxidative stress-induced cellular injury through the radical scavenging activities. In particular, the addition of green tea in seolitae chungkukjang showed stronger effect against oxidative stress induced by AAPH. The more addition of green tea resulted in the greater antioxidative effect through elevation in activities of SOD and GSH-Px, and inhibition of lipid peroxidation, eventually leading to increase in cell viability. Theses results suggested that seolitae chungkukjang added with green tea have protective effects from cellular oxidative damage and could be considered as an application for the development of chungkukjang with functionality.
Linking Ontologies to Business Process Schemas

This report intends to lay the formal foundations of a framework for the semantic augmentation of BP schemas, in order to provide a declarative representation of workflow models, enriched with domain knowledge encoded by means of computational ontologies. The proposed framework is centered around BPAL (Business Process Abstract Language), a logic-based language for modeling and reason with both the structural specification and the dynamic behavior of a business process from a workflow perspective. BPAL relies on a formalism, logic programming, that is particularly well-suited for its use within a wider knowledge representation framework, in particular in conjunction with rule based ontology languages to capture the semantics of a business scenario. The resulting Business Process Knowledge Base provides a uniform and formal representation framework, suited for automatic reasoning and equipped with a powerful inference mechanism supported by the solutions developed in the area of Logic Programming. At the same time it has been conceived to be used in conjunction with the existing BP management tools as an „add-on‟ facility, by supporting BPMN, in particular its XPDL linear form, as a modeling notation, and OWL, for the definition of the reference ontologies.
The idea mapping board: A tool for assessing design concepts and visualizing a team's use of the design space

This paper introduces the Idea Mapping Board, a visualization tool that supports the formation of shared mental models within design teams during concept generation and assessment. The Idea Mapping Board is intended for small teams of two to four practicing engineers or engineering students. It incorporates multiple dimensions for concept assessment based on cognitive level and cognitive style. We also present results from two pilot studies used to evaluate the effectiveness and ease of use of the Idea Mapping Board and its impact on the ideation flexibility of its users. This research is part of a larger project funded by the National Science Foundation (NSF) that investigates the impact of multiple factors, methods, and tools on the ideation flexibility of engineering students and practitioners. The Idea Mapping Board was created as part of our investigation of teaming as an intervention to help users expand their exploration of the design space.

X-UDeKAM: an intelligent method for acquiring declarative structured knowledge using Chatterbot

Declarative knowledge has a key role in health-care domain, which is hidden in multiple clinical-related knowledge resources. For acquiring and constructing the declarative structured knowledge from unstructured knowledge resources, UDeKAM methodology was proposed that lacks the intelligent human dialoguing mechanism for validating and filtering the important concept relations. This paper is the extension of our previous work and presents an extended version of UDeKAM, called X-UDeKAM, that includes Chatterbot along with text preprocessing as well as controlled natural language processing techniques. For realization of X-UDeKAM, a diabetes scenario is explained through example.
