An Experimental Investigation Into the Effect of Wakes on the Unsteady Turbine Rotor Flow

Detailed measurements were carried out near and within a turbine rotor using the Laser-2-Focus velocimeter. Testing was performed in a single stage cold air turbine at off-design conditions with a stator outlet Mach number of approximately 0.8. Instantaneous and averaged results of the velocity, the yaw angle, and the turbulence intensity provided information on the rotor flow field. This report describes the periodical and random unsteady effects of the stator wakes impinging on the rotor blades. In particular the constant unsteadiness contours clearly disclose the development of the wakes cut by the rotor blades. The objective of the study was to gain more insight into unsteady flow phenomena affecting losses, heat transfer, and related problems.
Integrating three-dimensional sustainability in distribution centre selection: the process analysis method-based analytic network process

In this paper, we propose a combined methodology for the selection of distribution centres (DCs) by integrating and balancing economic, environmental and social sustainability aspects. The analytic network process (ANP) permits to systematically evaluate possible DCs on the basis of a situation-specific decision structure. A systematic development of the decision networks, which is one of the core challenges using the ANP, is supported by the process analysis method which we extend for that purpose. The validity and soundness of the proposed framework are demonstrated by means of a case study. The case study results reveal that omitting aspects of sustainability can lead to unfortunate results.
Reevaluation of Total‐Column Ozone Trends and of the Effective Radiative Forcing of Ozone‐Depleting Substances

We evaluate total‐column ozone trends using a piecewise linear regression approach and maximizing usage of five gridded total‐column ozone data sets. The new approach yields more consistent estimates of observed ozone loss during 1979–2000, when halocarbon concentrations were increasing, and consequently, using CMIP6 simulations, an increased effective radiative forcing estimate of ozone‐depleting substances with a substantially reduced uncertainty range versus an earlier evaluation. At more than 84% confidence, it is now larger than zero and compares more favorably with three previous evaluations. We furthermore find significant positive post‐1997 global‐ and Southern‐Hemisphere‐mean trends, respectively, in these five data sets. For the extrapolar region ( 60° S– 60° N) and for the Northern Hemisphere, the assessment whether there is a positive trend is inconclusive and depends on which observational data set is included in the calculation.
Lateral Structural Deformation in Frontal Impacts

This paper describes how lateral deformations can occur as a result of various mechanisms in frontal crashes. Unfortunately, the crush energy associated with such deformations cannot be assessed as long as the structural properties are unknown. That has been the situation to date, due to the lack of appropriate crash test data. The paper attempts to address this deficit. A passenger car was crash-tested in a mode designed to induce lateral deformations that are significant compared to longitudinal crush. This was done via a series of three repeated impacts on the same vehicle so as to obtain, in a cost-effective manner, structural characterization data at increasing crash severities. Various cause-and-effect relationships (structural characterization models) were considered with an eye to selecting the one that best predicts the crush energy. Insights obtained from analyzing the behavior of the front structure are presented. The derived structural model is presented, along with recommendations regarding its use. Structurally, the test vehicle initially loads primarily in compression, until lateral forces induce significant bends in the load-bearing structures, causing them to deform under more-or-less constant force.
Statistical Analysis of Wind Power Density Based on the Weibull and Rayleigh Models of Selected Site in Malaysia

The demand for electricity in Malaysia is growing in tandem with its Gross Domestic Product (GDP) growth. Malaysia is going to need even more energy as it strives to grow towards a high-income economy. Malaysia has taken steps to exploring the renewable energy (RE) including wind energy as an alternative source for generating electricity. In the present study, the wind energy potential of the site is statistically analyzed based on 1-year measured hourly time-series wind speed data. Wind data were obtained from the Malaysian Meteorological Department (MMD) weather stations at nine selected sites in Malaysia. The data were calculated by using the MATLAB programming to determine and generate the Weibull and Rayleigh distribution functions. Both Weibull and Rayleigh models are fitted and compared to the Field data probability distributions of year 2011. From the analysis, it was shown that the Weibull distribution is fitting the Field data better than the Rayleigh distribution for the whole year 2011. The wind power density of every site has been studied based on the Weibull and Rayleigh functions. The Weibull distribution shows a good approximation for estimation of wind power density in Malaysia.
Load Testing of 30-year-old AASHTO Type III Highway Bridge Girders

As part of a bridge reconstruction project in Florida, American Association of State Highway and Transportation Officials (AASHTO) Type III girders were salvaged from an almost 30-year-old bridge. This paper reports on load tests that were conducted on these girders. Specimens were tested in three-point bending at shear span–to–depth ratios (a/d) ranging from 1.2 to 5.4. The age of the structure, lack of confinement steel, performance of horizontal and vertical mild steel in the end region, presence of end diaphragms, and the combination precast/cast-in-place concrete bridge deck were considered in the testing. The results gave no indication of reduced capacity or performance due to age or exposure. Girders tested with short shear spans (a/d < 3.1) exhibited a bond-shear failure mode categorized by cracks in the strand development zone, slipping of the strands, and failure to reach moment capacity. Mild steel reinforcement in the end region improved the capacity by 25% beyond the point where strand slip was detected. The single girder tested with an a/d of 5.4 failed in flexure. One of the two girders tested with an a/d of 4.2 exhibited abrupt bond-shear failure, while the other exhibited abrupt shear-compression failure. Experimental capacities were compared with sectional models, strut-and-tie models, and the end-region requirement for longitudinal reinforcement in the AASHTO Load and Resistance Factor Design specifications. The sectional models predicted generally conservative shear capacities. No adverse effects from the bridge deck system were observed.
Economics of Increased Beef Grader Accuracy

USDA grader called yield grade was compared to a calculated yield grade based on ribeye area and fat thickness measured by trained technicians. The predicted yield grade from the measurement was contrasted with the called yield grade distribution for two different time periods (January 2000- June 2003 and July 2003 - June 2006) to see if the graders accuracy in predicting yield grade had changed with the incorporation of an additional grader to the line. Grader accuracy did increase significantly with additional time to evaluate carcasses. A buying grid currently used by the industry was used to analyze the effect of the graders errors on the expected values of the premiums on both periods and by yield grade. The higher accuracy affected all yield grades, but most notably it resulted in more called yield grade 4 and 5 carcasses. As a result, grid premiums and net prices paid to producers decreased as graders tended to error toward the middle of the yield grade distribution, i.e., more Yield grade 3 and less 1's and 4's
Duration or Timing? What is the Optimal Core for Older Adults to Engage in Moderate-to-vigorous Physical Activity to Prevent Disability?

Background The positive association between the total duration of physical activity and performances of physical function may vary at different times of the day as circadian rhythm regulates individuals in response to external stimulations. We aimed to examine the association of timing-specific and overall moderate-to-vigorous physical activity (MVPA) with performances of physical function in older adults. Methods A cross-sectional analysis was conducted among 118 older adults (mean age = 70.0 ± 5.0 years). We assessed and identified timing-specific (morning: 06:01-12:00; afternoon: 12:01-18:00; evening: 18:01-24:00) and overall MVPA using a triaxial accelerometer. Different measures of physical function were evaluated including handgrip strength (by grip dynamometer), gait speed (five-meter walk test), basic functional mobility (timed up and go test), and lower limb strength (five times sit-to-stand test). Multivariate linear regression models adjusting for covariates were used to investigate the associations. Results Participants spent 0.4 hours in MVPA per day on average, half the time spent during the morning (47.7%), followed by during the afternoon (29.9%) and evening (21.6%). The time spent on overall MVPA was generally associated with better physical function performances. There was statistical evidence for the percentages of MVPA engagement during the morning ( B = 0.214, 95% confidence interval [CI] 0.001 to 0.428) and afternoon ( B = -0.273, 95% CI -0.518 to -0.027) associated with basic functional mobility but with contrary directions; the percentage of MVPA engagement during the evening was associated with less time spent in gait speed performance ( B = -0.237, 95% CI -0.468 to -0.006). Conclusions Our findings inform implications that the overall MVPA engagement was more important than timing-specific MVPA to older adults’ physical function performances. Strategies for accumulating time of MVPA is more practical and effective than encouraging to engage MVPA in specific timing for the enhancement of functional ability and therefore prevent disability among older adults.
Verformungsberechnung einer Unterwasserbetonbaugrube auf der Grundlage hypoplastisch ermittelter Parameter des Berliner Sandes

Bodenparameter beziehen sich immer auf ein bestimmtes Stoffgesetz. Die Anwendung elastisch‐idealplastischer Stoffgesetze verlangt bei den meisten kommerziellen FE‐Programmen die Bestimmung einer großen Anzahl von Stoffparametern, da die Steifemodule und Reibungswinkel von Druck und Dichte abhängen. Dagegen kommt das hypoplastische Stoffgesetz mit nur wenigen Parametern aus, die druck‐ und dichteunabhängig sind und mit granulometrischen Eigenschaften eng zusammenhängen. Die Bestimmung der hypoplastischen Parameter wird für Berliner Sand durchgeführt, und es wird gezeigt, wie konventionelle Steifigkeits‐ und Festigkeitsgrößen mit Hilfe des hypoplastischen Stoffgesetzes berechnet werden können. Die anschließende FE‐Berechnung einer einfach verankerten Baugrube in Berlin wird mit dem Mohr‐Coulombschen Stoffgesetz und mit aus der Hypoplastizität bestimmten Bodenparametern durchgeführt. Die Rechenergebnisse weisen eine gute Übereinstimmung mit gemessenen Werten auf. Es werden jedoch gleichzeitig die Grenzen einer solchen Vorgehensweise genannt, und der Bedarf umfassender Stoffgesetze in komplexeren Randwertproblemen wird betont.

Ant Colony Optimization for Design of Space Trusses

This paper presents two mechanisms to improve Ant Colony Optimization (ACO) for design of truss structures. The Sub-Optimization Mechanism causes the reduction in the search space, the size of the trail matrix and the decision vector; consequently, the optimization process is performed in smaller time. The Scatter Memory Mechanism introduces a matrix for saving the best scatter order and enables the ACO-based algorithms to reduce the number of ants and intensity of the analyses. The proposed mechanisms applied to ACS and ASrank are tested on two benchmark trusses from literature. The results for different algorithms demonstrate the efficiency of the proposed mechanisms.
Consumer E-Loyalty for E-Grocery Shopping in a Metro City of India

This study focuses on the e-loyalty of the grocery consumers. Understanding online behavior in developing countries is an emerging issue in these days. The purpose of this research is to examine the effects of antecedents of flow on attitude and perceived ease of use in the context of online grocery purchase behavior in a developing country perspective. Further, the study also examines the role of attitude and perceived ease of use in building e-loyalty. The present study analyzes the data of 250 respondents collected through an online survey. The data were analyzed employing exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equational modeling (SEM). The results show that the flow variables (concentration and enjoyment) have a positive but differential effect on attitude towards online grocery purchase. However, both concentration and enjoyment were equally important in influencing the perceived ease of use. The study also found that attitude positively influences the e-loyalty, and perceived ease of use influences both attitude and e-loyalty.

Reduction of Composite Pellet Containing Indonesia Lateritic Iron Ore as Raw Material for Producing TWDI

Blast furnace process is still an important process for producing pig iron. The process needs high grade iron ore and coke. The two materials can not be found easily. In addition blast furnace process needs cooking and sintering plant that produces polluted gases. Utilization of composite pellet for pig iron production can simplify process. The pellet is made of iron ore and coal. In addition the pellet can be made from other iron source and coal. This paper discusses the evolution of phase during reduction of composite pellet containing lateritic iron ore. Fresh iron ore and coal were ground to 140 mesh separately. They were mixed and pelletized. The quantity of coal added was varied from 0 %, 20 % and 29 % of pellet weight. Pellets were heated with 10 °C/minute to 1100 °C, 1200 °C, 1300 °C and 1350 °C in a tube furnace and temperature was held during 10 minutes. Heated pellets were analyzed with XRD equipment. XRD of reduced pellets showed that iron phase change with coal and temperature. Lack of coal during heating results the re-oxidation of iron phases. This process is due to replacement of reductive atmosphere by oxidative atmosphere.
Silent Talking: Indigenous Media Policy and the Productivity Commission

The recent Productivity Commission inquiry into Broadcasting in Australia has acknowledged the important place of Indigenous production in the national mediascape. The inquiry's draft report recommended changes to the Broadcasting Services Act which take into account some aspects of the kind of cultural production going on now in the Indigenous media sector across Australia. However, while there have been some significant changes suggested, acknowledgment of the broader cultural importance of the sector and its potential remain unaddressed. Acknowledgment of the special place of Indigenous languages and cultures in the Broadcasting Services Act, for example, remains elusive to national policy-makers.
Determination of Stature from Anthropometric Measurements of Thyroid Cartilage in the Population of Punjab

The astonishing task of determining the identity of an individual has been simplified, with the innovation of scientific technologies like DNA fingerprinting in the developed countries. Yet the application of such advanced technologies in developing countries is still a daunting task due to its complexity. Anthropometric analysis for the identification of unknown bodies is reasonably productive owing to its inexpensiveness. The aim of this study was to correlate the anthropometric measurements of the thyroid cartilage with the stature of the individual. Thyroid cartilages from 300 post mortem cases done in native population of Punjab were studied anthropometrically. A total of seventeen anthropometric measurements of selected parameters of thyroid cartilage were defined, measured, and statistically correlated with the body length of the individual. The variables which were significantly correlating with the body length were further analysed by regression analysis for derivation of a regression equation.

Friedman and gates: Another look

A lack of consensus surrounds probability estimates provided by the two leading bid models, one by Friedman and the other by Gates. Each model relies on essentially the same information but arrives at different probabilities of submitting the winning bid. A synopsis of both Friedman's and Gates's models is provided, followed by a descriptive chronology of literature dealing with this controversy. To date, attempts to resolve this debate have been unsuccessful in formulating a consensus view of which model supplies the correct probability. Using a third bid model proposed by Carr as a base, sensitivity curves visually demonstrate both similarities and differences in the models resulting from hypothetical shifts in the underlying location and scale parameters of the bid problem. It is clear from these curves that both models are simultaneously correct and incorrect. Friedman's model is theoretically correct, yet the bid problem is incorrectly specified. Gates's model is practically correct, yet the formula .
Household Adoption of Seismic Hazard Adjustments: A Comparison of Residents in Two States

Residents of a high seismic hazard uvea were compared with those in a moderate seismic hazard area in terms of demographic characteristics, personal hazard experience, risk perception, hazard intrusiveness, and self-reported adoption of 16 hazard adjustments (preimpact actions to reduce danger to persons and property). The results show that the two locations differed substantially in hazard experience, somewhat less so in risk perceptions and hazard intrusiveness, and little in hazard adjustment. Multiple regression analyses supported a causal chain in which location and demographic characteristics cause hazard experience, hazard experience causes hazard intrusiveness, perceived risk causes hazard intrusiveness, and hazard intrusiveness causes the adoption of hazard adjustments.
Surface Characteristics of Aesthetic Nickel-titanium and Beta-titanium Orthodontic Archwires Produced by Plasma Electrolytic Oxidation (PEO) - Primary Results

Background/Aim: There is continuing interest in engineering esthetic labial archwires. The aim of this study was to coat nickel-titanium (NiTi) and beta-titanium (β-Ti), also known as titanium molybdenum (TMA), archwires by plasma electrolytic oxidation (PEO) and to analyze the characteristics of the PEO-surfaces. Materials and Methods: PEO-coatings were generated on 0.014-inch NiTi and 0.19x0. 25-inch β-Ti archwires. The surfaces were analyzed by scanning electron microscopy and stereomicroscopy. Cytocombability testing was performed with ceramized and untreated samples according to EN ISO 10993-5 in XTT-, BrdU- and LDH-assays. The direct cell impact was analyzed using LIVE-/DEAD-staining. In addition, the archwires were inserted in an orthodontic model and photographs were taken before and after insertion. Results: The PEO coatings were 15 to 20 µm thick and esthetically pleasing. The cytocompatibility analysis revealed good cytocompatibility results for both ceramized NiTi and β-Ti archwires. In the direct cell tests, the ceramized samples showed improved compatibility as compared to those of uncoated samples. However, bending of the archwires resulted in loss of the PEO-surfaces. Nevertheless, it was possible to insert the β-Ti PEO-coated archwire in an orthodontic model without loss of the PEO-ceramic. Conclusion: PEO is a promising technique for the generation of esthetic orthodontic archwires. Since the PEO-coating does not resist bending, its clinical use seems to be limited so far to orthodontic techniques using straight or pre-bended archwires.
