DIAGNÓSTICO MEDIANTE TÉCNICAS DE ULTRASONIDOS DEL FORJADO DE MADERA DEL REFECTORIO DEL CONVENTO DE SANTA CLARA EN CARMONA (SEVILLA)

Ultrasonic tests are an effective technique of getting adiagnosis of timber structures in historical buildings. Thistechnique is quite valuable to undertake a restoration job. Anew methodology of analysis and diagnosis of timber roofsthrough this non destructive technique is presented. The aim of this article is to get the state of damage and thebending strenght capacity of the timber roof of the Monasteryof Santa Clara in Carmona (Seville) dining´s room by usingthis technology. From the results obtained about the bending strenghtcapacity of the studied beams, it can be affirmed that thetimber roof is not able to support safely enough the new useproposed. Considering the historic and artistic importance of thistimber roof, we propose as a restoration methodology basedon hanging the roof through bolts from a reinforced concreteplatform built-in the perimeter walls. This solutionguarantees that the timber roof does not work, just adjustingthe distance between the bolts.
A JUMPING MULTIGRID METHOD VIA FINITE ELEMENT EXTRAPOLATION By Chuanmiao

The multigrid method solves the finite element equations in optimal order, i.e., solving a linear system of O(N) equations in O(N) arithmetic operations. Based on low level solutions, we can use finite element extrapolation to obtain the high-level finite element solution on some coarse-level element boundary, at an higher accuracy O(hi ). Thus, we can solve higher level (hj , j <∼ 2i) finite element problems locally on each such coarse-level element. That is, we can skip the finite element problem on middle levels, hi+1, hi+2, . , hj−1. Roughly speaking, such a jumping multigrid method solves an order O(N) = O(22di) linear system of equations by a memory of O( √ N) = O(2di), and by a parallel computation of O( √ N), where d is the space dimension.
Induction of a sentiment dictionary for financial analyst communication: a data-driven approach balancing machine learning and human intuition

ABSTRACT While sentiment dictionaries are easy to apply and provide reproducible results, they often exhibit inferior classification performance compared to machine learning approaches trained for specific application domains. Nevertheless, both approaches typically require manual data analysis. This paper develops a domain-specific dictionary using regularised linear models drawing from textual reports of financial analysts. The first evaluation step demonstrates that the developed financial analyst dictionary can explain cumulative abnormal stock returns related to earnings events more accurately compared to other finance-related dictionaries and sentiment classifiers. In a second step, the approaches are compared using manually annotated sentiment. The financial analyst dictionary is more accurate than other dictionary-based approaches, although it cannot compete with a pre-trained deep learning sentiment classifier. While we show that the proposed approach is suited for texts of financial analysts, it can be applied to other use cases. The approach realises context specificity while reducing extensive manual data analysis.

The governance role and activity in colleges of further education

This thesis examines the role of the board of governors in colleges of further education (FE). Despite being a significant area of activity, comprising over 440 colleges, which were allocated a total of three billion pounds of public money in 1998, FE remains a notably under-researched sector. This thesis contributes to the knowledge and understanding of the governance activity in the sector by going beyond demographic data and using a case approach to examine the nature of the work undertaken by the board. This work is also important because it is able to utilise data gathered from observations of a college board as it undertakes its work. Data has been gathered from four FE colleges and has been analysed using the framework of the three paradoxes set out by Ada Demb and F.F. Neubauer in their work "The Corporate Board". This thesis then, draws on established work to present and develop a model applicable to considering the governance issues in FE. The main conclusions of this thesis are that in order to maximise the board's contribution to strategy, two key issues need to be addressed: issues associated with the governance process and issues associated with the people involved in that process. A more widespread understanding and coherent approach to adopting the principles of the Carver model of Policy Governance across the sector, along with a reconsideration of the role of the Further Education Funding Council may go some way towards addressing process issues. However, boards also need to recognise that whilst an efficient process may provide the potential for the board to undertake its strategic role, there is a need to go beyond this and to develop ways and means of harnessing the skills and contributions of all board members in order to maximise their strategic role.
Fiber-coupled nanophotonic devices for nonlinear optics and cavity QED

The sub-wavelength optical confinement and low optical loss of nanophotonic devices dramatically enhances the interaction between light and matter within these structures. When nanophotonic devices are combined with an efficient optical coupling channel, nonlinear optical behavior can be observed at low power levels in weakly-nonlinear materials. In a similar vein, when resonant atomic systems interact with nanophotonic devices, atom-photon coupling effects can be observed at a single quanta level. Crucially, the chip based nature of nanophotonics provides a scalable platform from which to study these effects. This thesis addresses the use of nanophotonic devices in nonlinear and quantum optics, including device design, optical coupling, fabrication and testing, modeling, and integration with more complex systems. We present a fiber taper coupling technique that allows efficient power transfer from an optical fiber into a photonic crystal waveguide. Greater than 97% power transfer into a silicon photonic crystal waveguide is demonstrated. This optical channel is then connected to a high-Q (> 40,000), ultra-small mode volume (V 44% of the photons input to a fiber. This permits the observation of optical bistability in silicon for sub-mW input powers at telecommunication wavelengths. To port this technology to cavity QED experiments at near-visible wavelengths, we also study silicon nitride microdisk cavities at wavelengths near 852 nm, and observe resonances with Q > 3 million and V
Static Warning Signs of Occasional Hazards: Do They Work?

This article reports on a study examining the use and effectiveness of static signs warning drivers of non-permanent hazards. These warning signs are frequently used for occasional hazards such as wildlife crossings, falling rocks and icy bridges. A literature review was conducted and a survey was sent to state departments of transportation to review the current use of static warning signs for occasional hazards (SWSOH) and whether any research documents the effectiveness of these signs. The literature review revealed that there is a lack of distinction in the literature between warning signs for permanent potential hazards(curves, winding roads etc.) versus those for occasional hazards. Most studies investigating the effectiveness of SWSOH were conducted in comparison to unconventional or enhanced warning devices. The survey showed that most agencies had not done any evaluations of the effectiveness of SWSOH, but that most perceived that SWSOH were only somewhat effective. The criteria for the installation of SWSOH appear to be vague and arbitrary, largely relying on engineering judgment. About 20% of respondents considered tort liability and litigation as having an important role in the decision to use SWSOH. More than half of responding agencies reported using unconventional warning devices, such as static signs with flashing lights, and most considered these unconventional warning devices to be effective. The findings from this study highlight the need for more research to establish the effectiveness of various warning devices for occasional hazards.
Social Media Use (SMU) for Teaching and Learning in Saudi Arabia

This research aims to explore the factors of teaching and learning measurement through using social media, incorporating the literature of social media adoption on resource sharing, collaborating and communicating for educational purpose. The current research explore factors that perceived usefulness (PU), perceived ease of use (PEU), attitude toward use social media use have certain influence on adoption of resource sharing, collaboration and communication for educational use. Therefore, resource sharing, collaboration and communication influence educational use, while educational use influences PU, PEU, SMU and attitude toward the use (AT) of SMU for teaching and learning. Both the processes of collecting and analyzing the data followed the quantitative method. The main tool of data collection was a questionnaire that has been distributed among 236 students using stratified random sampling technique. The view of the students and their implication of social media use for teaching and learning were solicited through the questionnaire. The Statistical Package for the Social Sciences (SPSS) was used as the main tool in the process of data examination. The results of this research were related to two main constructs: teaching and learning as well as educational use. According to the results, it appears that perceived usefulness, perceived ease of use, attitude toward use, and social media are considered powerful determinants of the former while resource sharing, collaboration and communication were significant indicators of the latter. Educational use, PU, PEU, AT succeeded in explaining 74.9% of SMU for teaching and learning.
Complex permittivity measurement in dielectric waveguide filled with argon plasma

An experimental set-up to measure the standing wave pattern of dielectric waveguide filled with low pressure plasma has been developed and is reported in this paper. Through the analysis of this pattern together with a solution of the complex algebra dispersion equation, a method is developed to determine the complex plasma permittivity that fills the dielectric waveguide. The experimental apparatus to measure the standing wave pattern of surface wave consists of a coaxial electric probe mounted in a moving carriage. The output signal of the probe is connected to a microwave detector and this output is a measurement of the relative electric field of the axial probe position around the dielectric waveguide. The microwave energy that sustains the plasma comes from a rectangular resonator excited by a quasi-CW magnetron. In the resonator there is a suitable pair of sleeves that launch the microwave energy stored in the dielectric waveguide. For 2.45 GHz and 750W of microwave power input a complex relative permittivity of (8.7-j15.8)/spl times/10/sup -3/ is found.

Agile Estimating and Planning

I’ve been meaning to buy this book since its release, but Mike was kind enough to send me one for review. I’ve come to this book from a two year planning assignment on two large aerospace programs and prior experience as a Program Management Officer for the IT portion of a very large Department of Energy program. But these jobs are not my normal profession, which is Enterprise IT management and product development. I was pulled into these planning roles through proposal efforts that won and I was left to implement the plan. Be careful for what you wish.
Desorption kinetics of trichloroethylene and perchloroethylene from aged dense nonaqueous phase liquid‐contaminated soil

Batch experiments were conducted to investigate the desorption kinetics of a contaminated soil collected from a field site at Hill Air Force Base (AFB), Utah. The site has been contaminated with many dense nonaqueous phase liquids (DNAPLs), primarily trichloroethylene (TCE) and perchloroethylene (PCE), for more than 60 years. Similar desorptive behaviour of both TCE and PCE was observed: a stage of fast release of the contaminant at the start followed by a very slow stage. Moreover, it is suggested that not all the contaminant in the solid phase may be released to the aqueous phase, apparently due to the age factor. Local variations were observed in the effective diffusivity and other sorption‐related parameters across the site due to aquifer heterogeneity. Experimental results were then simulated using a numerical code based on the intraparticle diffusion model. Good agreement was found between both results.
Development of Occupant Injury Prediction Algorithms for Advanced Automatic Collision Notification by Numerical Crash Reconstructions

Prediction of injured body regions and injury severity from available accident data can lead to more appropriate and hastier emergency care in automotive accidents. The existing prediction method was based on statistical analysis of a massive amount of real-world accident data. However, numerical crash simulations were also considered to provide a virtual injury database in a relatively short time. Therefore, the purpose of this study was to develop and to evaluate a new method to obtain injury prediction algorithm by utilizing virtual database of numerous computer simulation results. Occupant and cabin were modeled as multi-bodies. The occupant models have geometries of typical Japanese adult males. The cabin model consists of safety restraint systems and interior panels. Acceleration and intrusion of the door panels during side impact were delivered to the occupant in the simulations. Hundreds of crash simulations were performed where crash parameters were changed systematically. The injury prediction algorithms were developed by logistic regression analysis of the database constructed from the results of the simulations. The algorithms correctly predicted more than half of the head, thorax, and thigh injuries in 48 accidents. However, this study neglected cabin deformation in frontal crash, break of door-window, as well as occupant’s age and gender, which may affect on the occupant responses and injury severities. These limitations might be the cause of the miss predictions of injury severity in the simulations. In this study, possibility of developing injury prediction algorithms by using numerical crash reconstructions was presented as a different approach from existing method that used real-world accident data. For more accurate predictions, improvement of the simulation models and consideration of occupant characteristics are required.
Exploring the Relationship Between Covert Narcissism and Amorality: The Mediating Influences of Self-efficacy and Psychological Entitlement

Narcissism, as a personality construct, has attracted attention from countless scholars across multiple disciplines. It has been suggested that two forms of narcissism exist (Wink, 1991) and research has supported the delineation of overt (grandiose) and covert (hypersensitive) narcissism (Dickinson & Pincus, 2003; Gabbard, 2009; Luchner, Houston, Walker, & Houston, 2011). To date, most of the research devoted to narcissism has been focused on the overt rather than the covert form (Cain, Pincus, & Ansell, 2008). Further, researchers propose that a decreased level of meaningful relational interactions among narcissists may result in a higher propensity for amoral behaviors. Thus, to extend the research the current study explores the influence of several mediating variables on the relationship between covert narcissism and amorality. The current study found a negative relationship between covert narcissism and self-efficacy as well as an anticipated positive relationship between covert narcissism and psychological entitlement. It was also observed that self-efficacy and psychological entitlement did partially mediate the relationship between covert narcissism and higher amorality, supporting the study’s predictions.

A hover test of a 0.658-scale model of a V-22 rotor and wing was conducted at the Outdoor Aerodynamic Research Facility at Ames Research Center. The primary objectives of the test were to obtain accurate measurements of the hover performance of the rotor system, and to measure the aerodynamic interactions between the rotor and wing. Data were acquired for rotor tip Mach numbers ranging from 0.1 to 0.73. This report presents data on rotor performance, rotor-wake downwash velocities, rotor system loads, wing forces and moments, and wing surface pressures.
The Wind-Shielding and Shading Effects of Trees on Residential Heating and Cooling Requirements

The US Department of Energy (DOE) has funded several research projects, including this study, to assess the effects of site design on building space conditioning energy use. An important strategy being investigated is the use of vegetation for shading, wind control, and temperature modification. The study described in this report has been conducted concurrently with a closely related research project at the Northeastern Forest Experiment Station of the USDA Forest Service in Pennsylvania. The objective of that project is to measure wind-speed reductions and solar obstructions caused by trees around representative houses within typical neighborhoods and to develop an empirical model for estimating these effects based on the physical characteristics of different neighborhoods (Heisler 1989). The objective of this work is to combine the results of the on-site microclimate measurements from the 1989 Heisler study with work in building energy simulation to calculate the energy impacts of the observed microclimatic changes due to trees.

Vitamin D status and cardiometabolic risk factors in Greek adolescents with obesity – the effect of vitamin D supplementation: a pilot study

Introduction Obesity is associated with cardiovascular disease (CVD) risk factors as well as decreased 25(OH) vitamin D serum levels. We aimed to study 25(OH) vitamin D levels in adolescents with obesity compared with normal weight controls in association with CVD risk factors, and the possible effect of vitamin D supplementation. Material and methods In a cross-sectional study, 69 obese and 34 normal-weight adolescents were included. In an interventional study 15 adolescents with obesity and vitamin D insufficiency were given 2000 IU vitamin D per os daily for 3 months. Results Adolescents with obesity had significantly lower 25(OH) vitamin D levels compared with normal-weight controls (12.0 (3.0–36.0) vs. 34.0 (10.0–69.0) ng/ml, respectively, p < 0.001). In adolescents with obesity, 25(OH) vitamin D was inversely associated with leptin even after adjustment for body mass index (BMI) (r = –0.340, p = 0.009). Conversely, 25(OH) vitamin D was not related with other parameters, such as BMI, blood pressure, lipids, glucose, insulin, homeostasis model assessment (HOMA) index, adiponectin, leptin/adiponectin ratio, and visfatin levels. Following supplementation in 15 vitamin D insufficient adolescents with obesity, 25(OH) vitamin D significantly increased (from 17.3 (12.5–27.8) to 32.6 (14.3–68.0) ng/ml, p = 0.005) and so did low-density lipoprotein cholesterol (LDL-C) (from 85.4 ±9.5 to 92.1 ±15.8 mg/dl, p = 0.022), while there were reductions in glycated haemoglobin (HbA1c) (from 5.8 ±0.2 to 5.5 ±0.1%, p = 0.03) and leptin (from 19.7 (7.8–45.5) to 15.1 (4.3–37.3) ng/ml, p = 0.03). Oxidised LDL, paraoxonase, arylesterase, and urine isoprostanes remained unchanged. Conclusions Adolescents with obesity had lower 25(OH) vitamin D, which may be associated with higher leptin levels. Vitamin D supplementation may lead to HbA1c and leptin reductions, but also to an increase in LDL-C.
