AN AB INITIO INVESTIGATION OF THERMOELASTIC PHASE TRANSFORMATIONS IN TRANSITION METAL ALLOYS A Dissertation

The energy pathways associated with the martensitic transformation in shape memory alloys (SMAs), though the focus of extensive research over the past decades, are still unclear. In this work, we use a first-principles approach within the framework of density functional theory, as implemented in the Vienna ab initio simulation package (VASP), to model the transformation in transition metal alloys by tracking atomic motion via shear, shuffle and distortion during the transformation. We build a framework to investigate the f.c. c-h.c. p transformation in Co-based binary alloys which may be applied to ternary alloys as well. In the Co2NiGa Heusler system, by applying the Burgers transformation, we found a low-energy phase with orthorhombic symmetry (O) phase which is lower in energy than the experimentally observed L10. By performing a detailed analysis of the transformation paths (Burgers and Bain) taking into account perturbations on the ground state, it is seen that a phase selection problem exists: the ultimate crystal structure that the system transforms into, depends on the path that the system prefers. When coming from high temperature, the accessible path is that corresponding to the Bain transformation. Finally, we present a complete and unique 4-parameter model to describe the B2 − B19′ transformation in Ni − Ti. We eliminate the possibility of the B19 phase being an intermediate phase in the transformation and show that it is in fact a barrierless transformation. Crystallographic analysis of intermediate states shows that the B2−B19′ path follows a known crystallographic path.
- 1-UK REITs Don ' t Like Mondays 1

Purpose: The research examines whether REITs returns on the different days of the week differ from each other. Design/methodology/approach: It uses EPRA/NAREIT UK Index daily closing values (GBP) and its two sub-indices FTSE EPRA/NAREIT UK REITs and NonREITs as dependent variables. It employs Kruskal-Wallis (KW) tests and dummyvariable regression to test the hypothesis. Findings: The overall findings provide evidence that return anomalies exist in the UK REITs. Practical implications: Thought significant, the absolute returns differences are modest for investors to gain superior returns in UK REITs. However, by recognising the day-of-the-week effect, investors can buy/sell UK REITs more effectively.
GEODER ~ Multi-domain model for pore-size dependent transport of solutes in soils

A multi-domain model for the transport of chemicals in soils is developed. The solute flux is related to the microscopic water flux, which is modelled using concepts to estimate the hydraulic conductivity of porous media. The pore space of the soil is divided into an arbitrarily large number of domains each representing an equivalent pore radius. The domains are arranged on a structural coordinate, perpendicular to the direction of mean water flow. Transport in the flow direction takes place in each domain by convection and diffusion with pore-size specific velocities. Solute mixing between the domains is simulated as convective-dispersive transport along the structural coordinate. The model is solved numerically for one-dimensional steady-state water flux under unit-gradient conditions. Required input parameters are the unsaturated conductivity function of a soil and a pore interaction coefficient which characterizes the solute exchange between the pore domains. Simulations show a gradual change from convection dominated transport (isolated tube model) to convective-dispersive transport. The length scale where this change takes place depends on the lateral mixing intensity, pore-size distribution of the medium, and saturation degree.
Assessment of Anxiety and Depression in Patients Who Underwent Amputation

DOI: 10.21276/sjams.2017. 5.10. 4 Abstract: Limb loss is one of the most physically and psychologically devastating events, evokes many negative impacts (e.g. depression, anxiety). So in our study we tried assessing the anxiety and depression experienced by patients who underwent amputation getting discharged from hospital using HADS. Through this attempt we came to know that age and gender of the patient and level amputation had significant correlation with total HADS score. As prevalence of amputation and emotional disturbances resulting from it are increasing in India, we want to throw a light on it through our cross-sectional study.
Financial Development and Pre-historic Geographical Isolation : Global Evidence Oasis

Using cross-country differences in the degree of isolation before the advent of technologies in sea and air transportation, we assess the relationship between geographic isolation and financial development across the globe. We find that pre-historic geographical isolation has been beneficial to development because it has contributed to contemporary cross-country differences in financial intermediary development. The relationship is robust to alternative samples, different estimation techniques, outliers and varying conditioning information sets. The established positive relationship between geographic isolation and financial intermediary development does not significantly extend to stock market development. JEL: F15; G15; N7; O16; O50
THE IMPACT OF DIFFERENT CUES ON THE MEMORABILITY OF SYSTEM-ASSIGNED RECOGNITION-BASED TEXUAL PASSWORDS by KANIS FATEMA

THE IMPACT OF DIFFERENT CUES ON THE MEMORABILITY OF SYSTEM-ASSIGNED RECOGNITION-BASED TEXUAL PASSWORDS Kanis Fatema, M.S. The University of Texas at Arlington, 2015 Supervising Professor: Matthew Wright To ensure memorability, users employ predictable patterns when creating new passwords. These patterns make passwords easy to guess, which not only increases risks to users but also for the entire system. In contrast, system-assigned textual passwords o er security but su er from poor memorability. Previous research investigated the idea of textual recognition, in which the user would be assigned a word from a list and asked to recall the word later. The recall rate for this scheme was shown to be no better than memorizing a sequence of randomly assigned letters, but the researchers suggested that memorability may be improved if the words always appear in the same position in the list. This proposal to leverage spatial cues inspired us to explore the use of cues, including spatial but also verbal and graphical cues, to improve memorability in textual recognition. In particular, we design three schemes with di erent cues to see the impact of each cue. TextS is a textual recognition scheme with spatial cues, such that the words appear in the same position each time. TextSV is similar to TextS, but it also o ers verbal cues, i.e., phrase/facts related to keywords for textual
Ja n 20 16 Lower-Vietoris-type Topologies on Hyperspaces Elza

We introduce a new lower-Vietoris-type hypertopology in a way similar to that with which a new upper-Vietoris-type hypertopology was introduced in [4] (it was called there Tychonoff-type hypertopology). We study this new hypertopology and, in particular, we generalize many results from [3]. As a corollary, we get that for every continuous map f : X −→ X , where X is a continuum, there exist a subcontinuum K of X such that f(K) = K. MSC: 54B20, 54H25, 54F15, 54C05.
Removal of Heavy Metals from Aqueous Solution using Bamboo Based Activated Carbon

This study investigated the removal of cadmium and lead from aqueous solution using bamboo activated carbon. Bamboo activated carbon was prepared by physicochemical activation using ZnCl2 at different impregnation ratios (1:2; 1:3; and 1:4) ZnCl2/Bamboo. Batch adsorption studies were conducted to evaluate the optimum conditions for adsorption of cadmium and lead. Their adsorption isotherms were also determined by correlating with Langmuir, Freundlich, Temkin and Hills isotherms models using regression analyses. The kinetic studies were correlated with pseudo first order and pseudo second order equations. The results showed that the amount of cadmium and lead adsorbed increased as the adsorbent dosage decrease while the percentage removal rate increased with increase in cadmium and lead concentrations. High removal efficiency of 83.44% and 96.09% was achieved at pH 9 and pH 11 within 1.5hrs and 1hr using 50μm particle size for cadmium and lead, respectively. The equilibrium data fitted into Freundlich, Temkin and Hills isotherm but fitted precisely into Freundlich isotherm with Kf values of 7.01 and 2.128mg/g for cadmium and lead, respectively. The rate of adsorption could be described by Pseudo second order equation, indicating a chemisorptions process onto heterogeneous surfaces forming multilayer on the surface of activated carbon.
C O ] 5 F eb 2 01 9 Structure and properties of large intersecting families

We say that a family of k-subsets of an n-element set is intersecting, if any two of its sets intersect. In this paper we study different extremal properties of intersecting families, as well as the structure of large intersecting families. We also give some results on k-uniform families without s pairwise disjoint sets, related to Erdős Matching Conjecture. We prove a conclusive version of Frankl’s theorem on intersecting families with bounded maximal degree. This theorem, along with its generalizations to crossintersecting families, implies many results on the topic, obtained by Frankl, Frankl and Tokushige, Kupavskii and Zakharov and others. We study the structure of large intersecting families, obtaining some general structural theorems which generalize the results of Han and Kohayakawa, as well as Kostochka and Mubayi. We give degree and subset degree version of the Erdős–Ko–Rado and the Hilton– Milner theorems, extending the results of Huang and Zhao, and Frankl, Han, Huang and Zhao. We also extend the range in which the degree version of the Erdős Matching conjecture holds.
Numerical simulation of aluminum alloy quenching by direct thermal-mechanical coupling method and evolution of the elastic-plastic area

The CFD coupling flow model is established and refrigerated truck experimental platform is built. The internal temperature field in the refrigerated truck is studied by applying mathematical statistics and the fact that the internal temperature field varies with the environment temperature and the speed of the truck with fresh pork in it is analyzed. The conclusion that the variety of the external temperature has a greater influence on the variety of the internal temperature when the refrigerated truck is at a high speed is arrived. The raise of temperature in the top jet area inside the refrigerated truck is obvious and the internal area temperature near side walls of the refrigerated truck is relatively high
Evaluating sustainable UK social housing projects : An exploration of current practice

Purpose – This paper assesses the selection and use, in practice, of appraisal frameworks regarding sustainability evaluation in UK social housing sector projects, which have been advocated by academics as a means of ensuring that business decisions related to potential built environment projects are driven by best value rather than lowest cost. It also seeks to identity the key features of sustainability as assessed at the project feasibility stage. The research context is housing regeneration projects undertaken by UK social housing providers. Design/methodology/approach – Using a quantitative approach, a survey was conducted of 481 built environment professionals working within the UK social housing sector, which generated an overall response rate of 24%. Research Limitations/implications – The methodological approach adopted failed to uncover fully the reasons why practitioners selected particular types of sustainability appraisal toolkits. Findings The survey results revealed that few toolkits and models developed by academe to facilitate the development and evaluation of sustainability-led building projects have so far been adopted. The impact of organisational factors such as size, denomination, and maturity on the frameworks was analysed and, in general, no statistically significant relationship was found between organisational features and the models in use. The principal features of sustainability were found to be related to energy efficiency and asset life expectancy. These findings have implications for the UK construction industry’s commitment to enhancing the built environment’s sustainability and thereby stakeholder prosperity. Implications – This paper focuses on the current use of sustainability-led project appraisal models and the key features of sustainability whilst also providing directions for further research. It explores the adoption of sustainability-focused project evaluation practices in the UK social housing sector and outlines potential areas for further research, focused on developing a usable, holistic framework for evaluating sustainability during the early stages of project development to help to create a more sustainable built environment.
Understanding social learning behaviours of xMOOC completers

This paper is about the experiences with the first two MOOCs developed and executed at the Delft University of Technology (TUD) on the edX platform. The courses Solar Energy (ET3034TU) and Introduction to Water Treatment (CTB3365) have a long tradition at the TUD as regular campus courses with a good reputation worldwide. The focus of Solar Energy was on the discovery of solar energy power and the design of a complete photovoltaic system. This was done by introducing the students to the technology for the conversion of solar energy into electricity, heat and solar fuels with a main focus on electricity generation. The focus of the Water Treatment course was to learn about urban water services, including basic drinking water and wastewater treatment technologies. These two treatment chains were described as well as the physical, chemical and biological processes involved. The emphasis was on water quality and the functionality of each unit process within the treatment chain. In relation to their “MOOC”-characteristics, similarly to many other xMOOCs, these two DelftX courses had low completion rates, “knowledge-acquisition” approach to learning design, and relatively low forum activity.
APPLICATION OF THE MAMDANI FUZZY INFERENCE SYSTEM TO MEASURING HRM PERFORMANCE IN HOTEL COMPANIES – A PILOT STUDY

A new method based on fuzzy logic principles for measuring HRM performance is proposed where the Mamdani Fuzzy Inference System (MFIS) as a measurement tool is used with the intention to provide a contextual approach (hotel industry) and in which a score for HRM indicators is calculated for each activity. A survey of HR managers was conducted and an expert group was included to create rules for evaluating HRM performances. Four models where domain, functions and membership rules are set for each HRM activity could be used as a template for measuring HRM performance in middle-sized hotel companies.
GPU-SPH simulation of Tsunami-like wave interaction with a seawall associated with underwater

Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to prepare a reliable design. This study aimed to investigate the interactional effects of water waves generated by underwater disturbances on sea walls through numerical modeling using the Smoothed Particle Hydrodynamics (SPH) method. The simulation was performed using the Dual-SPHysics numerical code. Comparison of the numerical results with the experimental data extracted from case studies demonstrated the good capability of the SPH algorithm used in the numerical code in the simulation of initial wave generation by the underwater disturbance and its propagation over the body of water. To examine the wave force exerted on the walls, the results of laboratory experiences on the effect of tsunami waves on coastal structures were used to verify the numerical model. The study found that the phenomena with such nonlinear behavior can be very well simulated with a calibrated SPH model. We also explored the effects of this type of wave and temporal changes of its resultant force on the wall. In this article, the explosion-generated water wave produced much stronger fluctuations in the vicinity of the wall than did the solitary wave, thus naturally, it can be more destructive.
A new integrated approach for risk analysis and performance evaluation of a hospital sterilization service

In this work, we are interested in developing an integrated approach that combines simulation and risk analysis in the sterilization service, in order to take into account the effects of risks in the evaluation of the system performance. Our approach consists in creating an operating model of the sterilization service in order to describe the characteristics of the system. This system is subject to a multitude of risks, which can disrupt its operation. To take these risks into account, an analysis was carried out. The risks analyzed are integrated into the operating model in order to obtain a risk model. This model is simulated using a SIM.JS library using a JavaScript programming language. This simulation made it possible to evaluate the system performance in its different behavior modes (normal mode, degraded, reconfigured).
Validating Hotelling ’ s T 2 Diagnostics in Mixtures

Let Y0=[Y1, . ,Yn] be k–dimensional Gaussian vectors having the common mean μ and dispersion matrix Σ. To identify outlying shifts of type {Yi→Yi+δ}, Hotelling’s Ti diagnostics properly account for dependencies among the k elements of Yi. This study reconsiders the use of Ti under failure of the classical venue that [Y1, . ,Yn] themselves are mutually independent. Diagnostics for the case k=1 include those of Dixon (1950), Grubbs (1950) and Ferguson (1961) based on order statistics, and the R– Student deletion diagnostics ti , all predicated on independent observations. To relax the latter, Jensen and Ramirez (2015) recently showed these procedures to remain exact in level and power under specified dependencies among [Y1, . , Yn], and for scale mixtures of these dependent distributions. These findings are in keeping with correlated data, as found in the analysis of calibrated measurements, for example. Specifically, Hotelling’s Ti diagnostics are shown here to remain exact in level and power for dispersion mixtures of matrix Gaussian errors having star–shaped contours, to considerably enhance their range of applicability.

RHODAMINE-B DYE PHOTODEGRADATION ON Fe-DOPED TiO 2 NANOPARTICLES SYNTHESIZED BY FLAME SPRAY PYROLYSIS

Fe-doped TiO2 nanoparticles, with varied iron to titanium atomic ratio from 0 to 10% were synthesized by flame spray pyrolysis (FSP) process, and were used as a photocatalyst for waste water management (Rhodamine B dye degradation). Particle morphology, phase formation, and elemental structure were studied using XRD, Raman, ICP-OES, BET, TEM/HRTEM, EDS, and XPS. For pure TiO2 nanoparticles (~20 nm), anatase was the dominate phase, while iron doping promoted the formation of the rutile phase. EDS, and HRTEM confirmed that iron was uniformly doped within TiO2. A mixture of Fe 2+ and Fe 3+ was observed for the samples, where at lower iron concentration Fe 2+ was common, while Fe 3+ was dominant at higher iron concentration. The band gap for Fe-doped TiO2 was shifted lower by ~1eV when compared to pure TiO2 and UV-vis confirmed the increased absorption in the visible light region. Finally, the photocatalytic activity of the prepared nanoparticles was assessed by the photo-degradation of organic pollutants under visible-light irradiation. Rhodamine B (Rh-B) was used as a model organic pollutant found in waste water containing dye. The results indicated that Fe-doping enhanced the photo-reactivity of the TiO2 nanoparticles with the highest degradation efficiency obtained at 10% Fe in TiO2.
Impact of Family Involvement on the Bank Performance and Risk Taking Behavior : Evidence from Islamic Countries

The study aims to investigate the impact of family involvement, measured by two dimensions: family involvement in ownership (FIO) and family involvement in (FIM) on financial performance (FP) and risk taking behavior (RTB) of financial institutions. The study analyses FP as well as RBT of family owned banks in four Islamic countries (Pakistan, Jordon, Turkey and Malaysia) over the period of 2009 to 2016. The data are collected from twenty family owned banking institutions from the said countries i.e. seven banks from Jordan, four banks from Turkey, four banks from Malaysia and five banks from Pakistan. FIO (FIM) shows positive (negative) impact on bank financial performance and risk taking behavior simultaneously. The study recommends increasing FIO and decreasing FIM in family owned sampled banks for improving the FP and RTB. The study supports the agency theory as well as corporate governance ́s separation of ownership and control theorem.
Scissurellidae and Anatomidae from Manazuru , Sagami Bay , and Okinawa , Japan ( Mollusca : Gastropoda : Vetigastropoda )

Three new Scissurellidae and one new Anatoma (Anatomidae) are described from Cape Manazuru, Sagami Bay, and Okinawa, Japan. Sinezona costulata n. sp. from Sagami Bay has a protoconch with strong axial cords, the apertural varix is not connected to the embryonic cap, and the teleoconch sculpture is initially of strong axials, which are replaced on the shoulder at the apertural margin by fine spiral lines. Sinezona milleri n. sp. from Okinawa has a similar protoconch to S. costulata, and the teleoconch sculpture gives rise to a reticulate pattern at the apertural margin. The seven described and two new Japanese species of slit-bearing Scissurellidae are compared. Coronadoa hasegawai n. sp. from Sagami Bay is the second species in the genus and is characterised by distinct sculpture on the embryonic cap of the protoconch. Anatoma parageia n. sp. from Sagami Bay is a rare example of a shallow water anatomid. The shell is covered with numerous very fine axial cords that form minute, spirallyarranged points giving the impression of spiral sculpture (pseudospirals), and has undulating axial cords on the base. Depth preferences of Scissurellidae and Anatomidae are examined on a world-wide scale, but no change in turnover depth with latitude could be detected. The depth preferences of the two families are most likely explained by the extent to which variable food sources can be utilised.
Running Head: EMOTIONAL COMPETENCE AND EMOTION WORK

Emotion work, that is, the regulatory effort to express organizationally desired emotions, is an integral part of service work. The concept of emotional competence encompasses skills that focus on how people deal with and regulate their own affect and that of others. Although focusing on similar processes, there has been a lack of integration between these two concepts. The general hypothesis in this study was that emotional competence can be regarded as an important personal resource in service work because it moderates the relationships between work characteristics, emotional dissonance, and outcome variables. Eighty-four service employees completed a questionnaire on their working conditions and their well-being. In additions, peer-ratings for emotional competence were completed. We found that emotional competence moderated most of the proposed relationships (1) between work characteristics and emotional dissonance, (2) between emotional dissonance and outcome variables, and (3) between work characteristics and outcome variables.
