A Bayesian assessment for railway track geometry degradation prognostics

Advanced PHM techniques have the potential to substantially reduce railway track maintenance costs while increasing safety and availability. However, there is still a significant lack of knowledge and experience in relation to suitable PHM models and algorithms within the context of railway track geometry degradation. This paper proposes a Bayesian model class methodology for prognostics performance assessment whereby different prognostics algorithms can be rigorously assessed and ranked according to their relative probability to predict the future degradation process. The proposed framework is exemplified and tested for a case study about track degradation prognostics using published data about track settlement, taken from a simulated traffic loading experiment carried out at the Nottingham Railway Test Facility.
Whence Brand Evaluations? Investigating the Relevance of Personal and Extrapersonal Associations in Brand Attitudes

A recent conceptualization of the structure of attitudes proposes that people may hold associations that contribute to their personal attitudes about an object (personal associations) but also highly salient associations that do not contribute to their attitudes toward the object (extrapersonal associations; Olson and Fazio 2004). We conducted three studies with brands in the automobile industry to investigate the applicability of this new association typology to consumer attitude domains. Study 1 suggests the presence of extrapersonal associations for all brands investigated, by showing that some highly salient brand associations indeed contribute to brand attitudes but other similarly salient associations do not. Experimental data in Study 2 indicate that an individual difference, consumer expertise with the category, impacts the accessibility of personal associations in a brand evaluation context. Study 3 further strengthens the validity of the new typology by showing that it can meaningfully explain the different types of associations made accessible by persuasive messages. Taken together, our three studies provide strong support for Olson and Fazio's (2004) framework and highlight its value for a better understanding of the nature of the brand associations that shape consumer brand attitudes.
Comparison of Heat Transfer Measurements With Computations for Turbulent Flow Around a 180 deg Bend

Results of detailed heat transfer measurements are presented for all four walls of a 180 deg 1:1 aspect ratio duct. Experiments using a transient heat transfer technique with liquid crystal thermography were conducted for turbulent flow over a Reynolds numbers range of 12,500-50,000. Computational results using a Navier-Stokes code are also presented to complement the experiments. Two near-wall shear-stress treatments (wall functions and the two layer wall integration method) were evaluated in conjunction with k-e formulation of turbulence to assess their ability to predict high local gradients in heat transfer
Entrepreneurship in the Development of an Agile Enterprise : Theoretical and Practical Aspects

Given the growing importance of agility in contemporary organisations, it is imperative to investigate how to understand the characteristics of the agile enterprise. The aim of this article is thus to identify entrepreneurial behaviour in an agile enterprise and the strategic implications of agility. This paper draws on entrepreneurship and strategic management literature and a case study. The paper first examines the context of entrepreneurship and it then moved on to discuss the attributes of an agile enterprise. Then the issue under discussion is illustrated through a case study of Hortimex, an eminent representative of the leading food additives manufacturers in Poland. The findings of this case highlight the characteristics of agile enterprise in a contemporary business environment. It shows that attributes namely entrepreneurial resourcefulness and strategic leadership help to enhance the capability of a firm to compete in an increasingly intensified business environment.

Effects of Vitamins in Augmentation of Malaria Treatment: A review

Malaria continues to cause significant morbidity and mortality in several settings in the tropical regions of the world despite the availability of efficacious and potent antimalarial drugs. This has led to an increased interest in and evaluation of micronutrients which are well known to have antioxidant effects. However, the interaction of micronutrients with malaria is not well characterized and there are conflicting results on their impact. This review examines, in particular, the relationship between vitamin supplements and malaria treatment. Data indicate that concurrent use of vitamins with antimalarial drugs may either accelerate the potency of the drugs or antagonize their effects. Also, evidence do exist that deficiencies of some of these supplements may protect, exacerbate or have both effects on malaria parasitemia, depending on the settings. Therefore, it is safe to speculate that the use of antimalarial drugs alongside vitamins should be approached with caution, in order to not undermine the potency of the drug and to assure effective disease treatment.
Defining a cluster market: The case of the Korean internet portal service market

In a cluster market, many related and unrelated products or services are sold. Examples of cluster markets are Tesco, Sears, Carrefour, Walmart, JCPenny, and Meijer. Because of certain unique characteristics of cluster markets, studies of cluster market definition have been very scant. This paper reviews the market definition issues of cluster markets, proposes a statistical market definition method for cluster markets, and applies the method to the Korean Internet portal service market. The results of analyses show that there is one market for the Korean Internet portals and confirm the concern that the a priori definition of the Internet portal service market using a representative group of services like 1S4C, which was used by the Korea Fair Trade Commission in 2008, did not reflect the actual structure of competition in the Korean Internet portal service market. According to the analyses, the third ranked player in the Korean Internet portal service market, Nate, is more akin to a specialty service provider, not a player competing in the cluster market with Naver and Daum.
Low-Power, High-Throughput, Unsigned Multiplier Using A Modified Cpl Adder Cellfor Signal Processing Circuit

This paper proposes a full adder circuit that was designed by the Multiplexing Control Input Technique (MCIT) for a sum operation and the Boolean identities used for the carry operation. The proposed adder was implemented into the design of an 8x8-bit array multiplier circuit, specifically Braun, Baugh-Wooley (a 2's complement generator) and Modified Baugh-Wooley (with optimised interconnections) circuits that were designed for unsigned numbers. The 8x8-bit multiplier circuit was schematised by the DSCH2 VLSI CAD tool, whereas their layouts were generated by the Microwind 3 VLSI CAD tool. Output parameters, such as propagation delay, total chip area, and power dissipation are calculated from the simulated results. This paper extends to analyses for Energy Per Instruction (EPI), throughput, and latency by using the BSIM 4 advanced analyser. The power dissipation, EPI, throughput and area were analysed for different feature size. From these analyses of simulated results, it was found that the proposed adder-based multiplier circuit achieves better power dissipation and throughput performance than existing circuits.
A Simple Efficient Stopping Criterion for Turbo Decoder

The performance of a turbo decoder depends strongly on the number of iterations in its decoding process. It is necessary to stop the decoding process at an appropriate moment to alleviate the serious burden, in terms of both the computational speed and latency, part of which is associated with too many iterations. In this letter, we introduce a criterion for finding the opportune moment to stop the decoding process, called a hard decision aided criterion based on bit interleaved parity, which is known to have much simpler hardware logic, compared with other schemes, and does not lead to any significant performance degradation.
The relationship between semen parameters in processed and unprocessed semen with intrauterine insemination success rates

Objective: To evaluate the relationship between semen parameters and intrauterine insemination (IUI) success rates. Material and Methods: This retrospective study was conducted during a 4-year period (2011-2015) on the medical records of 350 couples admitted to the infertility center of Beast Hospital in Tehran. The participants’ data such as age, duration of infertility, semen parameters [including volume, concentration, motility, normal morphology and total motile sperm count (TMSC)] before and after sperm processing, as well as the IUI results were extracted from the patients’ records. Only the first IUI cycle of the couples was considered. The main outcome criterion for the IUI success was serum positive beta human chorionic gonadtotropin 14 days after IUI. The collected data were analyzed using the Mann-Whitney U test, chi-square, and Fisher’s exact tests. Results: The overall pregnancy rate for each couple was reported as 23.42% (82/350). There was no significant difference in the mean age of the couple and infertility duration between the groups who achieved pregnancy and those who failed. The two groups showed no significant differences in pre and post processing of semen parameters (including volume, concentration and TMSC). Sperm motility and normal sperm morphology before and after sperm processing were significantly different between the two groups, respectively (p=0.023 before sperm processing and p=0.032 after) (p=0.032 before sperm processing and p=0.007 after). Conclusion: Sperm motility and normal sperm morphology have an effect in IUI success.
Kinetics of the response of milk and serum b-carotene to daily b-carotene supplementation in healthy , lactating women 1 – 3

Changes in concentrations of milk and serum carotenoids, retinol, and a-tocopherol of five healthy, well-nourished, lactating women were measured over a 28-d supplementation trial with 30 mg b-carotene and for 4 wk thereafter. bCarotene supplementation increased mean b-carotene concentrations in milk and serum 6.4and 7.4-fold, respectively. Concentrations of other major carotenoids, retinol, and a-tocopherol did not change substantially in either milk or serum. Uptake of bcarotene into both serum and milk followed apparent first-order kinetics, occurring more rapidly into serum (t1/2 = 5.5 d) than into milk (t1/2 = 9 d). After supplementation, milk and serum b-carotene concentrations decayed slowly, reaching approximately twofold initial concentrations by 4 wk. Kinetics of uptake and decay in milk b-carotene concentrations paralleled those in serum. The data show that short-term supplementation of healthy, lactating mothers with purified b-carotene at approximately fivefold the average daily dietary intake substantially increased milk and serum b-carotene concentrations while not interfering with concentrations of other carotenoids, retinol, or a-tocopherol in milk or serum. Thus, an increased intake of b-carotene by healthy, lactating women increases the supply of milk b-carotene available to their breast-feeding infants. Am J Clin Nutr 1998;67:276–83.
EFFECT OF NON-METALLIC INCLUSIONS ON FORMATION OF STRUCTURE OF THE WELD METAL IN HIGH-STRENGTH LOW-ALLOY STEELS

Investigated was the possibility of using the oxide metallurgy approaches providing for control of the amount, distribution and morphology of the inclusions in metal melts, which affect conditions for formation of microstructure of the weld metal. It was shown that increase in the content of the fine-grained secondary phase can be achieved by varying the content of the fine carbide phase in structure of the weld metal. A high density of distribution of the 0.3—1.0 μm inclusions containing titanium or zirconium oxides leads to formation of the bainitic structure, whereas the decreased content of carbon in metal and narrowing of the range of bainitic transformations limit the probability of formation of the upper bainite microstructure. It was found that to provide the microstructure characterised by a combination of high values of strength, ductility and toughness it is necessary to form inclusions of a certain composition, size and distribution density in the weld metal. This can be achieved by using the oxide metallurgy methods, which provide for addition of a certain amount of refractory inclusions to the weld pool, limitation of its oxygen content and selection of the deoxidation system, as well as of the required temperature range of intermediate transformations based on the TTT-diagrams and welding thermal cycle. 12 Ref. , 9 Tables, 13 Figures.
C V ] 3 J un 2 01 6 CONCAVE UNIVALENT FUNCTIONS AND DIRICHLET FINITE INTEGRAL

Abstract. The article deals with the class Fα consisting of non-vanishing functions f that are analytic and univalent in D such that the complement C\f(D) is a convex set, f(1) = ∞, f(0) = 1 and the angle at ∞ is less than or equal to απ, for some α ∈ (1, 2]. Related to this class is the class CO(α) of concave univalent mappings in D, but this differs from Fα with the standard normalization f(0) = 0 = f (0) = 1. A number of properties of these classes are discussed which includes an easy proof of the coefficient conjecture for CO(2) settled by Avkhadiev et al. [3]. Moreover, another interesting result connected with the Yamashita conjecture on Dirichlet finite integral for CO(α) is also presented.
Trace-element fractionation by impact-induced volatilization : SIMS study of lunar HASP samples

Impact is a dominant process acting on the surfaces of planetary bodies and is the major process that modifies the physical and chemical nature of planetary materials on atmosphere-free bodies once volcanic activity has ceased. Elements with relatively high volatilities are readily mobilized during impact. HASP (high alumina, silica poor) compositions are thought to be generated by impact-induced volatilization processes on the moon. The high AVSi ratio of HASP is believed to be the result of preferential loss of SiO, relative to AlrO. Here we report SIMS analyses for HASP glass beads and devitrified glasses from the Apollo 14 regolith to assess the behavior of Li, Be, B, REE, Sr, Y and Zr duing impact events. We compare the behavior of these fface elements to the behavior of major and minor elements analyzed by the electron microprobe. The HASP samples we studied fall into two compositional groups with one group apparently derived from KREEPy lunar lithologies and the other from anorthosite. The KREEPy HASP beads have an estimated mass loss of 28Vo compared to their KREEPy protolith. We estimate that 44Vo of SiO, and 35Vo of FeO were lost during impact-induced volatilization. The mass loss estimate for the anorthositic protolith to produce anorthositic HASP is more uncertain because of the uncertainity of the protolith composition. However, an estimate of -25Vo appears reasonable with 387o loss of silica. Clearly, impact processes, in the early stages of planetary evolution, are important in the modification of geochemical signatures, and ordinarily geochemically coherent elements may be decoupled because of different volatilities.
‘Residual diversity estimates’ do not correct for sampling bias in palaeodiversity data

It is widely accepted that the fossil record suffers from various sampling biases – diversity signals through time may partly or largely reflect the rock record – and many methods have been devised to deal with this problem. One widely used method, the ‘residual diversity’ method, uses residuals from a modelled relationship between palaeodiversity and sampling (sampling‐driven diversity model) as ‘corrected’ diversity estimates, but the unorthodox way in which these residuals are generated presents serious statistical problems; the response and predictor variables are decoupled through independent sorting, rendering the new bivariate relationship meaningless. Here, we use simple simulations to demonstrate the detrimental consequences of independent sorting, through assessing error rates and biases in regression model coefficients. Regression models based on independently sorted data result in unacceptably high rates of incorrect and systematically, directionally biased estimates, when the true parameter values are known. The large number of recent papers that used the method are likely to have produced misleading results and their implications should be reassessed. We note that the ‘residuals’ approach based on the sampling‐driven diversity model cannot be used to ‘correct’ for sampling bias, and instead advocate the use of phylogenetic multiple regression models that can include various confounding factors, including sampling bias, while simultaneously accounting for statistical non‐independence owing to shared ancestry. Evolutionary dynamics such as speciation are inherently a phylogenetic process, and only an explicitly phylogenetic approach will correctly model this process.
ENVIRONMENT IN THREE CLASSES OF ENDOGENOUS GROWTH MODELS

The implications of environmental externalities are studied within three classes of endogenous growth models viz. the linear technology models, the human capital models, and the RD the direction of change depends on the severity of extemalities and the intertemporal elasticity of substitution. The presence of environmental externalities cause the decentralized growth rate to diverge from the efficient rate. Which rate is bigger than the other depends, among other things, on the valuation of consumption relative to environmental quality. Several policy changes to align the two paths are discussed. The models are calibrated to U.S. data.
Reproduction Biology of the Garfish, Belone euxini Günther, 1866 (Belonidae: Belone) in the Southeast Black Sea

To describe the reproduction biology of the garfish, Belone euxini and differences in parameters from other populations, monthly sampling were conducted between December 2011 and July 2013 in the southeast Black Sea. Absolute fecundity ranged between 4015 and 32453 (mean: 14365±1049) and mature eggs that was left for each spawning portion (batch fecundity) ranged between 560 and 9713 (mean: 2338±243). Correlation coefficient of fecundity and total length relationships were significantly different from zero. Mean diameter of immature eggs in ovary was significantly lower than mature eggs (ttest: P = 1.54E-230). The proportion of mature eggs in the ovary ranged between 8% and 34% (mean: 16%±0.7) and the number of batches was obtained between 3 and 12 (mean: 6.8±0.3) times in a year. Monthly proportion of gonad maturity stages and monthly GSI values showed that the spawning period of garfish was between May and September. The size at first sexual maturity (TL50) was estimated as 34.4 cm TL for females and 33.3 cm TL for males. The results of this study were offered as biological input parameters regarded as a reference for management of Black Sea stocks of the garfish species.

Universities and Smart Specialisation

Universities have a potentially pivotal role to play in the social and economic development of their regions. They are a critical ‘asset’ of the region; even more so in less favoured regions where the private sector may be weak or relatively small, and has low levels of research and development activity. Evidence shows that the successful mobilisation of the resources of a university can have a disproportionately positive effect on regional economies and achievement of comprehensive regional strategies. Universities can therefore play a key role by contributing to the design and implementation of S3 in a local learning and capacity building process. However there are some key underpinning principles that make smart specialisation distinctive from previous iterations of regional innovation strategy development, and it will be necessary to understand the implications of these for the actors in the process, including universities.
Analysis of supplier involvement in new product development and launch

New or innovative products are growing in importance both in numbers and revenues, putting an extra stress on most current supply chains defined conceptually as a buyer with a network of suppliers as those were originally designed for efficiency purposes and existing products. While new products due to their characteristics, such as short life cycle, demand variability, and high investment risk, require responsive, flexible, adaptable supply chains and relevant practices. Those practices need to be properly tailored for specific different types of new products, perceived as a continuum of newness and change. This thesis examines supply chain management and supplier management practices for new products across different industries. This study has been conducted within the MIT Supply Chain 2020 Initiative using the academic and business literature research and an online survey as the methodology, and new product analytical framework as the study deliverable. The results of this study demonstrate that though there is a pronounced tendency to use suppliers more extensively to improve new product performance and general competitiveness, companies approach the supplier new product involvement very differently depending on the type of new product in question and the specific mix of its key activity categories, which were identified in this study and corresponding framework as Flexibility, Control, Technology and Cost Focus.
