Extreme vertical wave impact on the deck of a gravity-based structure (GBS) platform

A simple method for solving water impact loads on decks of offshore structures is developed. In the present paper the emphasis is on vertical wave-in-deck loads. The suggested method is three-dimensional and valid for general deck geometries and arbitrary incident wave direction. First and second order wave amplification due to the large-volume structure is included in the analysis. The method is implemented into a numerical simulation program. This tool uses the results from an a priori second order diffraction analysis of the platform hull as input. In particular the wave-in-deck simulation program applies computed linear and quadratic transfer functions from the diffraction analysis as input. The method is validated against experiments. Results from scaled model tests of a gravity-based structure (GBS) are compared to numerical results. The platform was subjected to extreme waves causing water impact on the deck structure. In the present work, only impact from regular waves is considered. Satisfactory results are obtained from the numerical simulations. The theoretical results compare well with the experiment. The vertical loads on the deck are well reproduced both during the water entry phase and the water exit phase. Moreover, the duration of the wave-in-deck event is satisfactorily predicted.
Gaming with Mr. Slot or Gaming the Slot Machine? Power, Anthropomorphism, and Risk Perception

We propose that risk perceptions are systematically influenced by anthropomorphism. Anthropomorphism effects, however, are moderated by the individual’s feelings of social power. People with low power perceive higher risk in playing a slot machine (study 1) and in getting skin cancer (study 2) when the risk-bearing entities (the slot machine and skin cancer) are highly anthropomorphized. In contrast, those with high power perceive greater risk when the entities are less anthropomorphized. We hypothesize these effects occur because those with high (low) power perceived a greater (lesser) degree of control over the anthropomorphized entity. In study 3, we investigate the reverse effect that higher perceived risk may increase anthropomorphism for people with low power but decrease anthropomorphism for people with high power.
Preferences of Tourists for the Service Quality of Taichung Calligraphy Greenway in Taiwan

This study explores preferences for a set of attributes that characterize the recreational value of Calligraphy Greenway, the most notable greenbelt in Taichung City, Taiwan. As an urban green space, the Calligraphy Greenway has its own recreational attributes and visitors’ preferences. This study uses the choice experiment method to determine visitors’ preference levels for five major attributes to improve the recreational quality. On average, each visitor visited there 9.15 times in the past year and spent 2.37 h per visit. Of the five recreational attributes, satisfaction with recreational activity opportunities had the highest score and satisfaction with cultural landscape resources had the lowest score. The importance is ranked in the order of recreational service quality, total recreational cost, environmental landscape resources, cultural landscape resources and recreational activity opportunities. Considering difference of groups, female visitors were more concerned with cost and activities but male visitors were more concerned with service quality and natural/cultural landscape resources. Local visitors were more concerned with cost and activities but non-local visitors were more concerned with environmental/cultural landscape resources. Both were concerned with service quality. Based on the results, this study makes the following recommendations: cultural landscape resources and quality of recreational services and facilities should be improved and more complete interpretative educational guidance should be provided to increase visitors’ willingness to visit. Additionally, it is suggested to set up various districts to cater for preferences of different visitor groups.
Process window for electron beam melting of Ti-6Al-4V

Selective electron beam melting (EBM) is a powder-bed based additive manufacturing technique for the fabrication of dense metallic parts. As a free-form deposition process EBM offers a high degree of freedom in design and a highly efficient utilization of material. For a widespread industrial application the achievable build rate is a critical factor. In this paper the process window for Ti-6Al-4V is explored by varying beam current and scan speed in a wide range. The EBM specimens were characterized by their density, porosity size and distribution, chemical composition, microstructure, hardness and tensile strength. Key findings include: (1) the minimum line energy necessary to achieve full density, (2) parameter sets for increased build rates at full density, and (3) formation of α'-martensite at high scan rates.
Spatial distribution of bivalves in relation to environmental conditions (middle Danube catchment, Hungary).

The spatial distribution of bivalves in relation to environmental conditions was studied along a second- and third order stream — medium-sized river (River Ipoly) — large river (River Danube) continuum in the Hungarian Danube River system. Quantitative samples were collected four times in 2007 and a total of 1662 specimens, belonging to 22 bivalve species were identified. Among these species, two are endangered (Pseudanodonta complanata, Unio crassus) and five are invasive (Dreissena polymorpha, D. rostriformis bugensis, Corbicula fluminea, C. fluminalis, Anodonta woodiana) in Hungary. The higher density presented by Pisidium subtruncatum, P. supinum, P. henslowanum and C. fluminea suggests that these species may have a key role in this ecosystem. Three different faunal groups were distinguished but no significant temporal change was detected. The lowest density and diversity with two species (P. casertanum and P. personatum) occurred in streams. The highest density and diversity was found in the River Ip.
An Evaluation of the Load-Displacement Behavior and Load Test Interpretation of Micropiles in Rock

This paper summarizes a series of never-before reported axial compression load tests conducted on single micropiles that are embedded in or constructed on rock. These data are augmented by load tests on similar micropiles that have been reported by others. The observed displacements at the maximum test load (QMAX) and reported unfactored design load (QDL) are summarized. In addition, the small-strain load-displacement behavior of these foundations is evaluated by comparing the initial tangent slope (IS) to the theoretical elastic slope (ES), which is calculated by modeling the micropile as a free-standing column exhibiting fully -composite behavior. The data demonstrate that the ES/IS ratio has a strong dependence on the slenderness ratio D[depth]/B[diameter]. The observed results for micropiles in rock are discussed in the context of the micropile load test acceptance criteria proposed by the Deep Foundations Institute (DFI, 2001). In addition, recommendations are proposed for the maximum acceptable vertical displacement under the unfactored design load for such micropiles.
Making Business-to-Business International Internet Marketing Effective: A Study of Critical Factors Using a Case-Study Approach

The recent phenomenal growth in business activities dependent on the Internet has demonstrated that various potential advantages could be derived from using information and communication technology platforms. The Internet has enabled firms to reach out to global markets and has provided them with the opportunity to customize their strategies and offerings in an unprecedented way. These recent developments provide an exciting opportunity for research to study the dynamics involved in international Internet marketing (IIM) and, in particular, to examine closely the factors that could influence success in using this new technology for IIM activities. Using a business-to-business context and a multiple-case-study approach, this article focuses on two main areas of study: (1) the critical examination of the literature and identification of the most important factors that have a significant influence on business-to-business IIM and (2) the first-hand verification of how the identified factors are implemented in various organizational contexts.
Effect of microstructural evolution on wettability and tribological behavior of TiO 2 nanotubular arrays coated on Ti – 6 Al – 4 V

Self-organized TiO2 nanotubular arrays were fabricated by electrochemical anodization of Ti–6Al–4V plates in an NH4F/H3PO4 electrolyte. The effect of microstructural evolutions on the wettability and tribological behavior of the TiO2 nanotubes was investigated. Based on the XRD profiles of the fabricated material, the characteristic TiO2 peaks were not recognized after anodization; however, highly crystalline TiO2 (anatase and rutile) was formed due to crystallization during annealing at 500 1C for 1.5 h. The nanotube arrays were converted entirely to rutile at 700 1C. From a microstructure point of view, a highly ordered nanotube structure was achieved when the specimen was annealed at 500 1C, with a length of 0.72 μm and a pore diameter of 72 nm. Further increasing the annealing temperature to 700 1C resulted in the complete collapse of the tubular structure. The results indicate that the improved wettability of the anodized specimens was due to the combination of the effects of both the surface oxide layer and the increased surface roughness achieved after anodization. Moreover, the wear resistance and wettability of the sample annealed 500 1C were improved due to the high hardness (435 HV) and low coefficient of friction (0.133–168) of the highly crystalline structure of the TiO2 nanotubes. & 2015 Elsevier Ltd and Techna Group S.r. l.

Intelligence and psychopathy: A study on non-incarcerated females from the normal population

Abstract Most research on the relation between psychopathy and intelligence has been conducted with incarcerated male samples. However, psychopathic traits can be found among non-incarcerated individuals, male or female, possessing high intellectual capacities. The construct of psychopathy has been comparatively understudied in women. We hypothesized a positive correlation between interpersonal psychopathic traits and intelligence among females, whereby those non-criminal females having high scores on these traits would be more intelligent than those having low scores on these traits. We carried out a correlational analysis and group comparisons on a sample of 121 non-criminal females. Variables that were measured include the Psychopathic Personality Inventory (PPI) total score and its two subscales; the Levenson Primary and Secondary Psychopathy (LPSP) total score and its two subscales; Psychoticism (P) and intelligence measured by Raven’s Standard Progressive Matrices (SPM). A significant positive correlation (r = .33, p < .05) was found between LPSP-I (interpersonal affective factor) and SPM. Separate ANOVAs were conducted to compare SPM scores of the participants, when they were allocated to groups based on either the PPI or the LPSP scores. Performance of the interpersonal affective group (M = 53.32, SD = 3.45) was better than that of the two other groups (M = 50.26, SD = 3.25 for “Impulsive Antisocial”, and M = 49.37, SD = 4.67 for “non psychopathy”).
Explaining authentic leadership work outcomes from the perspective of self-determination theory

The article examines the impact of authentic leadership in leader-follower relationship conceptualized from self-determination theory perspective. Authentic leadership enhances followers“™ intrinsic motivation, trust in organisation, commitment and overall job satisfaction. Intrinsic motivation of leaders“™ fosters internalization of authentic leadership values among employees. The intrinsically oriented followers are more engaged in effective authentic leader-follower relations, than the followers who possess extrinsic work value orientation. Authentic leadership relevance can be explained by followers“™ intrinsic or extrinsic work value orientation.
Approximately Normalized Iterative Hard Thresholding for Nonlinear Compressive Sensing

The nonlinear compressive sensing (NCS) is an extension of classical compressive sensing (CS) and the iterative hard thresholding (IHT) algorithm is a popular greedy-type method for solving CS. The normalized iterative hard thresholding (NIHT) is a modification of IHT and is more effective than IHT. In this paper, we propose an approximately normalized iterative hard thresholding (ANIHT) algorithm for NCS by using the approximate optimal stepsize combining with Armijo stepsize rule preiteration. Under the condition similar to restricted isometry property (RIP), we analyze the condition that can identify the iterative support sets in a finite number of iterations. Numerical experiments show the good performance of the new algorithm for the NCS.
Investigating Short Run Causality between Real GDP and Government Expenditure in India Since 1950s

This paper has examined short run causality between government expenditure and GDP in India during 1951-2013 using a Toda-Yamamoto (1995) modified Granger causality approach under VAR environment. Exponentially detrended annual time series data on GDP and government expenditure at constant prices are used. Structural break point unit root tests are conducted besides the usual unit root tests to determine the order of integration of each variable. Tests for structural breaks reveal significant breaks in both time series around the period 2001-04. Government expenditure is found to significantly Granger-cause real GDP but the converse is insignificant implying that Wagner’s law is inapplicable. The study thus suggests uni-directional causality from government expenditure to GDP. Moreover government expenditure in India has a long-run co-integrating relationship with real GDP and therefore short run causal relations may be anticipated. Keywords: Real GDP, government expenditure, Granger Causality, Toda-Yamamoto approach and VAR. JEL Classification: C32, E50, E52, E59.
Phytotoxicity of Sicyos deppei during tomato germination and its effects on the role of ABA and cell wall enzymes

Sicyos deppei is a harmful weed that grows in central Mexico, decreasing crop productivity by allelochemical release via lixiviation of the aerial organs through raining. S. deppei aqueous leachate is phytotoxic to tomato seed germination causing various metabolic alterations, such as high levels of abscisic acid, which delay germination and inhibit radicle growth. To determine whether abscisic acid catabolism was involved in the delay of germination caused by S. deppei , tomato seeds were exposed to diniconazole, an ABA catabolism-inhibitor, and subsequently the activity of cell wall-degrading enzymes (endo-β-mannanase, α-galactosidase, exo-polygalacturonase, and b-1,3-glucanase) was estimated in the presence of ABA, diniconazole and S. deppei aqueous leachate. Results showed that during germination, there is a delay in ABA degradation and the activity of the four cell wall-degrading enzymes evaluated was inhibited. Cell cycle was analyzed to characterize the inhibition of radicle growth during post-germination in the roots of treated seedlings. The phytotoxic aqueous leachate of S. deppei interfered with it, altering the expression of two cell cycle marker genes CDKB2;1 and CycB2;1 , thereby reducing cell division. In summary, the delay in tomato germination through S. deppei leachate reflects first that there is a delay in ABA catabolism, and second there is an alteration of cellular processes that interfere with cell cycle and inhibit radicle growth during postgermination.
The composition of board of directors

The Certificate of Incorporation of The Walt Disney Company provides that the Board of Directors shall consist of not less than nine or more than 21 Directors, with the exact number being determined from time to time by resolution of the Board. The Board believes that a desirable target number of Directors is 9 to 13, allowing, however, for changing circumstances that may warrant a higher or lower number.
An Extreme Value Theory Approach for Analyzing the Extreme Risk of the Gold Prices

Financial markets frequently experience extreme movements in the negative side. Accurate computation of value at risk and expected shortfall are the main tasks of the risk managers or portfolio managers. In this paper, gold prices (in US dollars) have been examined to illustrate the main idea of extreme value theory and discuss the tail behaviour. GEV and GPD are used to compute VaR and ES. The results show that GPD model with threshold is a better choice.
Business Cycle Implications of Habit Formation

The inability of a wide array of dynamic stochastic general equilibrium (DSGE) models to generate fluctuations that resemble actual business cycles has lead to the use of habit formation in consumption. For example, habit formation has been shown to help explain the negative response of labour input to a positive, permanent technology shock, several asset pricing puzzles, and the impact of monetary shocks on real variables. Investigating four different DSGE models with the Bayesian calibration approach, this paper observes that, especially in a new Keynesian monetary business cycle model with both staggered price and wage, habit formation fails to mimic the shape of output growth in the frequency domain: it counterfactually emphasizes low frequency fluctuations in output growth, compared to the U.S. data. On the other hand, habit formation has no clear implications on other business cycle aspects including impulse responses and forecast error variance decompositions of output to permanent and transitory shocks. These observations cast doubt on habit formation as an important ingredient of the DSGE model with a rich set of internal propagation mechanisms.
The role of the programmed cell death ( apoptosis ) in the vascular diseases — aortic aneurysm

In the paper a role of programmed cell death (apoptosis) in the vascular disease development was presented. The influence of apoptosis on the aortic aneurysm development was discussed. Characteristic cell changes concerning apoptotic cell death were described, including inducers and regulatory factors — especially Bcl-2 protein family and death receptors. According to the current multivariant theory concerning aneursym etiology, apoptosis can play the role in the decrease of the smooth muscle cell number in the medial aortic layer in the cases of aortic aneurysm and cystic medial degeneration. The role of inflammatory cells such as lymphocytes and macrophages and the factors inducing apoptotic cell death in the degenerative changes of the aortic wall is emphasized.
Regional carbon fluxes from land use and land cover change in Asia, 1980–2009

We present a synthesis of the land-atmosphere carbon flux from land use and land cover change (LULCC) in Asia using multiple data sources and paying particular attention to deforestation and forest regrowth fluxes. The data sources are quasi-independent and include the U.N. Food and Agriculture Organization-Forest Resource Assessment (FAO-FRA 2015; country-level inventory estimates), the Emission Database for Global Atmospheric Research (EDGARv4.3), the ‘Houghton’ bookkeeping model that incorporates FAO-FRA data, an ensemble of 8 state-of-the-art Dynamic Global Vegetation Models (DGVM), and 2 recently published independent studies using primarily remote sensing techniques. The estimates are aggregated spatially to Southeast, East, and South Asia and temporally for three decades, 1980–1989, 1990–1999 and 2000–2009. Since 1980, net carbon emissions from LULCC in Asia were responsible for 20%–40% of global LULCC emissions, with emissions from Southeast Asia alone accounting for 15%–25% of global LULCC emissions during the same period. In the 2000s and for all Asia, three estimates (FAO-FRA, DGVM, Houghton) were in agreement of a net source of carbon to the atmosphere, with mean estimates ranging between 0.24 to 0.41 Pg C yr−1, whereas EDGARv4.3 suggested a net carbon sink of −0.17 Pg C yr−1. Three of 4 estimates suggest that LULCC carbon emissions declined by at least 34% in the preceding decade (1990–2000). Spread in the estimates is due to the inclusion of different flux components and their treatments, showing the importance to include emissions from carbon rich peatlands and land management, such as shifting cultivation and wood harvesting, which appear to be consistently underreported.
The generation of Ganymede's diffuse aurora through pitch angle scattering

Abstract. Diffuse auroral intensities of neutral atomic oxygen OI λ 1356 A emission on Ganymede due to whistler mode waves are estimated. Pitch angle diffusion of magnetospheric electrons into the loss cone due to resonant wave–particle interaction of whistler mode waves is considered, and the resulting electron precipitation flux is calculated. The analytical yield spectrum approach is used for determining the energy deposition of electrons precipitating into the atmosphere of Ganymede. It is found that the intensities (4–30 R ) calculated from the precipitation of magnetospheric electrons observed near Ganymede are inadequate to account for the observational intensities (≤ 100 R ). This is in agreement with the conclusions reached in previous works. Some acceleration mechanism is required to energize the magnetospheric electrons. In the present work we consider the heating and acceleration of magnetospheric electrons by electrostatic waves. Two particle distribution functions (Maxwellian and kappa distribution) are used to simulate heating and acceleration of electrons. Precipitation of a Maxwellian distribution of electrons can produce about 70 R intensities of OI λ 1356 A emission for electron temperature of 150 eV. A kappa distribution can also yield a diffuse auroral intensity of similar magnitude for a characteristic energy of about 100 eV. The maximum contribution to the estimated intensity results from the dissociative excitation of O 2 . Contributions from the direct excitation of atomic oxygen and cascading in atomic oxygen are estimated to be only about 1 and 2 % of the total calculated intensity, respectively. The findings of this work are relevant for the present JUNO and future JUICE missions to Jupiter. These missions will provide new data on electron densities, electron temperature and whistler mode wave amplitudes in the magnetosphere of Jupiter near Ganymede.
Vehicle Remote Health Monitoring and Prognostic Maintenance System

In many industries inclusive of automotive vehicle industry, predictive maintenance has become more important. It is hard to diagnose failure in advance in the vehicle industry because of the limited availability of sensors and some of the designing exertions. However with the great development in automotive industry, it looks feasible today to analyze sensor’s data along with machine learning techniques for failure prediction. In this article, an approach is presented for fault prediction of four main subsystems of vehicle, fuel system, ignition system, exhaust system, and cooling system. Sensor is collected when vehicle is on the move, both in faulty condition (when any failure in specific system has occurred) and in normal condition. The data is transmitted to the server which analyzes the data. Interesting patterns are learned using four classifiers, Decision Tree, Support Vector Machine, Nearest Neighbor, and Random Forest. These patterns are later used to detect future failures in other vehicles which show the similar behavior. The approach is produced with the end goal of expanding vehicle up-time and was demonstrated on 70 vehicles of Toyota Corolla type. Accuracy comparison of all classifiers is performed on the basis of Receiver Operating Characteristics (ROC) curves.
