Large Eddy Simulation : A Useful Tool for Engineering Fluid Dynamics

This paper is dedicated to describe the current state-of-the-art in Large Eddy Simulation (LES) of practical engineering systems. As LES is used in a wide range of applications (aerodynamics, hydrodynamics, combustion etc.) an attempt is made here to provide a compact but still comprehensive description of the LES methodology and an overview of how LES is utilized to provide knowledge about practical engineering systems. Both theoretical aspects of LES, such as subgrid modeling and numerical methods, as well as examples of LES computations in the fields of aerodynamics, hydrodynamics and combustion are presented and discussed. In order to support these applied LES predictions some results for building block flows, for which experimental data is available, are also presented. In addition the issues of verification, validation and uncertainty quantification are also briefly described and discussed. The main conclusion is that LES provides a very useful computational tool for fluid mechanics that can and should be used together with other simulations models and experiments to advance the understanding of fluid flow and to aid the design of engineering systems. With present computational capabilities it is already now possible to gain fundamentally new insight into e.g. car, train and aircraft aerodynamics, ship hydrodynamics and combustion in a range of systems from gas turbines and IC engines, to scramjet engines and White Dwarf stars.

The aim of this study is to identify the psychological perception levels of the female inmates in Antalya Type-L Closed Penitentiary Institution and then to determine the effect of exercise on such perceptions. This is an experimental study with weak experimental design. Study sample consists of a total of 121 female prisoners; 32 in the experimental group, 43 in control group 1 and 46 in the control group 2. The data collection tools used in this study are Physical Activity Readiness Questionnaire for determining the physical activity levels of the individuals, Psychological Well-Being Scale, Beck Depression Inventory and State-Trait (STAI) Anxiety Inventory for identifying their psychological perceptions. T-Test, One-Way Analysis of Variance and LSD analysis -a Post-Hoc testwere used for data analysis. Consequently, the psychological perception levels of the female inmates before and after exercise were examined as per the groups they participated and the results revealed that there was no statistically significant difference among the depression, anxiety and psychological well-being levels of those inmates, who participated in the exercises. However, there was a significant increase on the depression levels in the control groups 1 and 2. In conclusion, it can be said that exercise plays an important role in protecting the psychological perceptions of the incarcerated individuals.
Live-In Versus Live-Out Home Care in Israel: Satisfaction With Services and Caregivers’ Outcomes

Purpose of the Study: The present study provides a preliminary examination of the relationship between the type of home care services (live-in vs. live-out; i.e., round the clock vs. several hours per week), the caregiver’s satisfaction with services, and the caregiver’s burden, distress, well-being, and subjective health status within the conceptual framework of caregiving outcomes proposed by Yates and colleagues (Yates, M. E., Tennstedt, S., & Chang, B. H. [1999]. Contributors to and mediators of psychological well-being for informal caregivers. Journal of Gerontology: Psychological Sciences, 54, P12 –P22. doi:10.1093/geronb/54B.1.P12). Design and Methods: A random stratified sample of family caregivers of older adults more than the age of 70 who receive live-in (442) or live-out (244) home care services through the financial assistance of the National Insurance institute of Israel was selected. A path analysis was conducted. Results: Satisfaction with services was higher among caregivers under the live-in home care arrangement and positively related to well-being. Among caregivers, live-in home care was directly associated with higher levels of subjective health and indirectly associated with better well-being via satisfaction with services. Implications: The present study emphasizes the potential benefits of live-in home care services for caregivers of older adults who suffer from high levels of impairment and the importance of assessing satisfaction with services as a predictor of caregivers’ outcomes.
1 Universal banking and the development of secondary corporate debt markets : Lessons from 1830 s Belgium by Working Paper

This paper proposes a reassessment of the old-age debate on universal banking and growth by putting it on a different plan. Modern financial economics are used to provide new theoretical foundations to Gerschenkron’s (1962) hypothesis: universality is interpreted as a strategy for banks to reach the critical size needed in order to perform successful securitization of corporate debt. A relevant natural experiment in universal banking and industrialization (Belgium in the 1830s) illustrates the argument. The conclusion is that creating a new financial market also implies establishing intermediaries to supply crucial functions such as underwriting, certification, and liquidity provision.

Degree of mapping 1 Tucker ’ s , Fan ’ s and Shashkin ’ s Lemmas

Tucker and Ky Fan’s lemma are combinatorial analogs of the Borsuk–Ulam theorem (BUT). In 1996, Yu. A. Shashkin proved a version of Fan’s lemma, which is a combinatorial analogof the oddmapping theorem (OMT). Weconsider generalizations of these lemmas for BUT–manifolds, i.e. for manifolds that satisfy BUT. Proofs rely on a generalization of the OMT and on a lemma about the doubling of manifolds with boundaries that are BUT–manifolds.
Application of Model Predictive Control for a Work Class Remotely Operated Vehicle*

The work-class Remotely Operated Vehicles (ROVs) are crucial for a broad range of underwater applications such as Inspection, Maintenance, and Repair (IMR) of subsea infrastructure, pipelines, and offshore wind farms. Despite the recent advances in the field of automation and robotics, the ROV operations are largely dependent on manual control. The common practice in the industry for controlling the ROV’s robotic arm involves using two pilots, one controlling the ROV and the other controlling the arm. To address this challenge, this paper applies nonlinear model predictive control (MPC) methodology to control the position of the tip of the robotic arm. To this effect, two separate MPC controllers are designed, one controlling the ROV and the other controlling the ROV’s manipulator. This configuration allows combining different control methodologies for controlling the ROV or its arm. It also facilitates a single pilot in the loop, controlling an arm or ROV while the other unit is controlled autonomously. Multiple configurations, with different controller types, including a unified MPC based controller for ROV plus its arm, are tested and compared using numerical simulations.
Adsorption of Cu(II), Ni(II) and Zn(II) Ions by Nano Kaolinite: Thermodynamics and Kinetics Studies

An easy route for preparation emulsion of kaolinite (Al2Si2O5.4H2O) from Sweileh sand deposits, west Amman, Jordan by hydrochloric acid under continuous stirring for 4 h at room temperature was performed and nano kaolinite powder was used as an adsorbent for the removal of Cu(II), Zn(II) and Ni(II) ions. Nano kaolinite was characterized by XRD, FT-IR and SEM techniques. Effect of pH, adsorbent dose, initial metal ion concentration, contact time and temperature on adsorption process was examined. The negative values of ΔGo and the positive value of ΔHo revealed that the adsorption process was spontaneous and endothermic. The Langmuir isotherm model fitted well to metal ions adsorption data and the adsorption capacity. The kinetic data provided the best correlation of the adsorption with pseudo-second order kinetic model. In view of promising efficiency, the nano kaolinite can be employed for heavy metal ions adsorption.
Chatterbox: Conversational Interfaces for Microtask Crowdsourcing

Conversational interfaces can facilitate human-computer interactions. Whether or not conversational interfaces can improve worker experience and work quality in crowdsourcing marketplaces has remained unanswered. We investigate the suitability of text-based conversational interfaces for microtask crowdsourcing. We designed a rigorous experimental campaign aimed at gauging the interest and acceptance by crowdworkers for this type of work interface. We compared Web and conversational interfaces for five common microtask types and measured the execution time, quality of work, and the perceived satisfaction of 316 workers recruited from the FigureEight platform. We show that conversational interfaces can be used effectively for crowdsourcing microtasks, resulting in a high satisfaction from workers, and without having a negative impact on task execution time or work quality.
Do as the Neighbors Do: The Impact of Social Networks on Immigrant Employment

Substantial immigrant segregation in the United States, combined with the increase in the share of the U.S. foreign-born population, have led to great interest in the causes and consequences of immigrant concentration, including those related to the functioning of labor markets. This paper provides robust evidence that both the size and the quality of an immigrant enclave affects the labor market outcomes of new immigrants. We develop new measures of the quality, or information value, of immigrant networks by exploiting data based on worker earnings records matched to firm and Census information. We demonstrate the importance of immigrant employment links: network members are much more likely than other immigrants to be employed in the same firm as their geographic neighbors. Immigrants living with large numbers of employed neighbors are more likely to have jobs than immigrants in areas with fewer employed neighbors. The effects are quantitatively important and robust under alternative specifications. For example, in a high value network – one with an average employment rate in the 90th percentile – a one standard deviation increase in the log of the number of contacts in the network is associated with almost a 5% increase in the employment rate. Earnings, conditional on employment, increase by about 0.7%.
Death by Market Power. Reform, Competition and Patient Outcomes in the National Health Service

The effect of competition on the quality of health care remains a contested issue. Most empirical estimates rely on inference from non experimental data. In contrast, this paper exploits a pro-competitive policy reform to provide estimates of the impact of competition on hospital outcomes. The English government introduced a policy in 2006 to promote competition between hospitals. Patients were given choice of location for hospital care and provided information on the quality and timeliness of care. Prices, previously negotiated between buyer and seller, were set centrally under a DRG type system. Using this policy to implement a difference-in-differences research design we estimate the impact of the introduction of competition on not only clinical outcomes but also productivity and expenditure. Our data set is large, containing information on approximately 68,000 discharges per year per hospital from 160 hospitals. We find that the effect of competition is to save lives without raising costs. Patients discharged from hospitals located in markets where competition was more feasible were less likely to die, had shorter length of stay and were treated at the same cost.
Use of Multi-Watermarking Schema to Maintain Awareness in a Teleneurology Diagnosis Platform

Following the tremendous evolution of transferring images through the Internet, it is necessary to ensure security during this act and mainly for medical images. The application of multiple watermarking technique represents a solution to preserve the security of this data, on the one hand, and the traceability of medical diagnoses made by doctors, on the other hand. This falls under remote collaborative work. This technique is applied in the TeNeCi (Collaborative tele-neurology) platform. This project allows practitioners to distribute the analyses of the medical image. In fact, we used the multiple watermarking technique in a wavelet field. The theory underlying this technique is to hide information in the medical image and to ensure at the same time its imperceptibility. The diagnosis made by the practitioner is the inserted data in the image. The fundamental challenge of this paper is how to hide the total diagnoses of each practitioner in the image ensuring a good quality of the image
The relationship between global longitudinal strain , myocardial storage and hypertrophy in cardiac Fabry disease

Cardiovascular magnetic resonance (CMR) can detect T1 lowering, representing myocardial sphingolipid storage. InIntroduction: Detecting early cardiac involvement in Fabry disease (FD) is important because therapy may alter disease progression. Cardiovascular magnetic resonance (CMR) can detect T1 lowering, representing myocardial sphingolipid storage. In many diseases, early mechanical dysfunction may be detected by abnormal global longitudinal strain (GLS). We explored the relationship of early mechanical dysfunction and sphingolipid deposition in FD. Methods: An observational study of 221 FD and 77 healthy volunteers (HV) who underwent CMR (LV volumes, mass, native T1, GLS, late gadolinium enhancement), ECG, and blood biomarkers, as part of the prospective multicenter Fabry400 study. Results: All FD had normal LV ejection fraction (EF 738%). Mean indexed LV mass (LVMi) was 89±39g/m in FD and 55.6±10g/m in HV. 102 (46%) FD participants had left ventricular hypertrophy (LVH). There was a negative correlation between GLS and native T1 in FD patients (r=-0.515, p<0.05). In FD patients without LVH (early disease), as native T1 reduced there was a reduction in GLS (r=-0.285, p<0.05), but only in males and not females (males: low T1 -18.3±1.6ms vs. normal T1 -20.0±1.0ms, p<0.05). ECG changes were not associated with impaired GLS. Conclusions: Fabry males have changes in myocardial deformation before the onset of LVH associated with sphingolipid deposition; females display mechanical dysfunction only once they develop LVH, supporting possible sex dimorphism in the early myocardial functional response to storage.
Flow Control over Airfoils using Different Shaped Dimples

The present work describes change in aerodynamic characteristics of an airfoil by applying certain surface modifications in form of dimples. At first surface modifications that are considered here are outward and Inward dimples on the wing model. A 2-Dimensional computational fluid dynamics CFD is done on both using k-w turbulence model, thereafter based on its results the better of the two is chosen. After choosing the better dimpled configuration, different shaped dimples are tested and compared to the plane airfoil model. This CFD analysis is done in 3-D by taking a segment of the airfoil with one dimple on it. A comparative study showing variance in lift and drag of modified airfoil models at different angle of attacks is done. The results were in agreement that dimples on the surface aircraft wing model doesn‟t affect the pressure drag much since it is already aerodynamic in shape but it can affect its aerodynamics when the airfoil is at different angle of attacks. This project verifies if the dimples that reduce a golf ball's drag, can also alter flow dynamics around airfoil for better aerodynamic efficiency. Dimples delay the boundary layer separation by creating more turbulence over the surface thus reducing the wake formation. This in turn reduces drag drastically. The airfoil profile considered in the present study is NACA-0018 with uniform cross-section throughout the length of airfoil. Subsonic flows are considered for the study. The CAD model is prepared in CatiaV5 R18 and simulations are carried out in Comsol 3.4 and Comsol 4.2a. The overall aim of the study is improved maneuverability and performance of an aircraft by flow manipulation over the airfoil. The results justify the increase in the overall lift and reduction in drag of the airfoil.
Models of ends of hyperbolic 3-manifolds. A survey

We survey bi-Lipschitz models for degenerate ends of hyperbolic 3-manifolds used in the resolution of the Ending Lamination Conjecture. A quick introduction to Fuchsian and Kleinian surface groups is included. We end with the use of the bi-Lipschitz model to prove the existence of Cannon-Thurston maps and local connectivity of limit sets.
The Epitome of the Russian National Idea: Comparative Reconstruction in Sculpture and Narrative

The formulation of the national idea for such a multinational country as Russia is a big issue. Its solution is not monopolized by the ideological institutions; art and popular mentality also contributes to the working out of the meaning for the unifying national idea. The author reconstructs those dominant meanings of the national idea (in art and popular consciousness) by the means of visual and textual analysis. The visual object for this reconstruction was realized by the sculpture that embodied the national idea of Russia at the International Art exhibition. The corpus of texts for the Russian contest that reflected the people’s ideas about the national idea was used in narrative analysis.
Incentivising Specific Combinations of Subjects – Does It Make Any Difference to University Access?

A major part of the 2010–15 UK government's education reforms in England was a focus on the curriculum that pupils study from ages 14–16. Most high profile was the introduction of the English Baccalaureate (EBacc) performance measure for schools, incentivising study of “subjects the Russell Group identifies as key for university study” (Gibb, 2011). However, there does not appear to be good quantitative evidence about the importance of studying such a set of subjects, per se. This paper sets out to analyse this question, considering whether otherwise similar young people who study specific sets of subjects (full set for EBacc-eligibility, two or more sciences, foreign languages, applied subjects) to age 16 have different probabilities of entering university, and specifically a high-status university. It compares results from regression modelling and propensity score matching, taking advantage of rich survey data from a recent cohort of young people in England. We find that conditional differences in university entry attributable to subject choice are, at most, small.

Speech recognition in adverse environment is one of the major issue in automatic speech recognition nowadays. While most current speech recognition system show to be highly efficient for ideal environment but their performance go down extremely when they are applied in real environment because of noise effected speech. In this paper a new feature representation based on phase spectra and Perceptual Linear Prediction (PLP) has been suggested which can be used for robust speech recognition. It is shown that this new features can improve the performance of speech recognition not only in clean condition but also in various levels of noise condition when it is compared to PLP features.

The paper investigates the behavior of digital PID self-tuning controllers (STC) in different structures of the control loops used in adaptive systems. In the two phases of this type of systems which use a STC-PID, the first phase, i.e. the task of recursive identification of the plant model parameters, is used a regression (ARX) model with the recursive least squares method. Because the quality of process model depends on the order of the ARX model and of the sample period (Ts), the digital PID parameters are functions of these variables and, supplementary, of continuous-time PID parameters and of the control loop structures used in the adaptive system (although, not so largely as the firstly three variables). To see the latter influence, in this paper are considered two control loop block diagram, and for simulations three different processes (stable; with no minimum phase; unstable), and some simulations with different , , T s n ! " . The PID controller design method used to obtain the specs desired for control loop dynamic behavior was the pole assignment method of the loop.

Turbulence measurements at high Reynolds numbers using a new inclined Nano-Scale Thermal Anemometry Probe

The first efforts towards building and testing a multicomponent Nano-Scale Thermal Anemometry Probe (NSTAP) are reported for studies of high Reynolds number turbulence. An inclined NSTAP has been fabricated and tested in a turbulent pipe flow over a range of Reynolds numbers and it is shown to be in good agreement with available data. Specifically, the results demonstrate the feasibility of implementing the inclined NSTAP design in wall-bounded turbulence at high Reynolds number.
