Full Text Available This commentary reviews the position articulated in an article published in 2004 that the business model prevalent in the automotive industry was inadequate to meeting the challenge of sustainability, and reviews the key developments since then. The most noticeable developments the commentary traces are the growth in academic interest in business models, a more responsive government policy particularly in respect of new technologies, and the practical application of the concepts and ideas mooted in the original paper, notably with respect to electric vehicles.
This Invited Commentary discusses the following article: BACKGROUND:: To identify the etiologies of adult Horner syndrome (HS) in the MRI era using a targeted evaluation approach and to assess the value and yield of targeted imaging. A retrospective chart review was performed of 200 adult outpatients with HS, confirmed with cocaine eyedrop testing. Patients were divided into subgroups based on the presence or absence of symptoms and those who did or did not receive additional testing with hydroxyamphetamine drops. Imaging was obtained based on pharmacologic localization and/or clinical evaluation. The etiology of HS and the yield of imaging were determined in all subgroups. Imaging showed causative lesions in 24 of 179 (12.84%) imaged patients with HS, and 13 (69.0%) were determined "idiopathic." Of the patients who underwent testing with hydroxyamphetamine drops (132 patients), 86 had a postganglionic localization with an imaging yield of 8.1%, and 46 had preganglionic cause with an imaging yield of 21.7%. Fifty-three patients (26.5%) never noticed ptosis/anisocoria before examination, and the imaging yield in this subgroup was 2.8%. Eighteen of the 200 patients (9.0%) had serious pathology, including carotid artery dissection, brain, or neck mass, and 6 of these (31.6%) had acute symptoms and/or pain. HS is most often idiopathic with serious pathology being relatively infrequent. When determining etiology, the absence of symptoms is not predictive of the pathology. However, acute onset of symptoms and/or pain are possible indicators for serious pathology. Localizing the lesion using hydroxyamphetamine drops whenever obtainable and available is still an efficient way to target imaging evaluation.

In this issue of the Journal, Snowden et al. (Am J Epidemiol. 2011;173(7):731-738) give a didactic explanation of G-computation as an approach for estimating the causal effect of a point exposure. The authors of the present commentary reinforce the idea that their use of G-computation is equivalent to a particular form of model-based standardization, whereby reference is made to the observed study population, a technique that epidemiologists have been applying for several decades. They comment on the use of standardized versus conditional effect measures and on the relative predominance of the inverse probability-of-treatment weighting approach as opposed to G-computation. They further propose a compromise approach, doubly robust standardization, that combines the benefits of both of these causal inference techniques and is not more difficult to implement.
In a 1986 article (Am J Epidemiol. 1986;124(6):903-915), Keys et al. described and discussed 15-year findings from 15 cohorts of the Seven Countries Study (SCS), the first systematic study of diet, risk characteristics, disease-specific death rates, and their ecologic and individual associations both among and within whole populations of working men in regions with contrasting traditional diets. The SCS findings included 30-fold cohort differences in rates of death from coronary heart disease and 3-fold differences in rates of death from all causes, along with strong ecologic associations among diet, risk factors, and disease rates. These results have motivated a generation of causal research conducted using bench, clinical, and population strategies. The study has contributed to survey methods, preventive practice, nutrition science, and policy on health, food and agriculture, and diet. The article is a succinct and accessible account by Ancel Keys, near the end of his long career, of the SCS design, conduct, and findings, with his discussion and interpretation of their importance. My commentary deals with the extent, validity, and historical meaning of SCS findings, as well as their influence and the influence of the 1986 article itself on epidemiologic thought and on public health. Students of epidemiology and of history should read this rich original source. © The Author 2017.

Introduces several commentaries on an article by U. Dinger et al (see record 200913603-002) entitled "Therapists' attachment, patients' interpersonal problems and alliance development over time in inpatient psychotherapy." This article represents an ambitious effort on the part of the researchers to map a number of interrelated relational variables, over the course of treatment, in a relatively understudied patient population. "Attachment," "interpersonal problems," and "alliance" are variables that capture core components of the therapeutic relationship and psychotherapy process that have been reliably linked to patient improvement in many previous studies of mostly outpatient psychotherapy. Jeremy Holmes (see record 2009-13603-003) and George Silbershatz (see record 2009-13603-004) were invited to comment on this study while wearing their clinical hats. They were asked about how they made sense of the research results as practicing psychotherapists, the ways in which the findings were useful to them as clinicians, and where they considered the research to be of more limited value from a clinical point of view. Following the commentaries is a final word from the authors of the study (see record 2009-13603-005). It is hoped that this format of dialogue will have an impact on how clinical research is presented in the future. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

Researchers across several disciplines have argued that the characteristics of neighborhood environments can affect a variety of individual- and neighborhood-level outcomes. Physical disorder is one feature of neighborhoods that scholars have argued is important, but data that capture physical disorder have been limited because of the time and resources required for in-person audits. The advent of Google Street View, which provides publicly available street-level imagery with nearly complete coverage of the United States, opens new possibilities for researchers. In this issue of the Journal, Mooney et al. (Am J Epidemiol. 2017;186(3):265-273) compare in-person and virtual audits in Detroit, Michigan, and demonstrate that virtual audits offer key advantages to measuring neighborhood physical disorder over in-person audits, including substantial reductions in time and resources with little to no loss of measurement precision. In this invited commentary, I welcome the use of virtual audits for advancing the study of neighborhoods and outline areas in which they can advance understanding of neighborhood effects. I also describe areas of caution in their implementation and outline how new innovations can advance the use of virtual audits for furthering understanding of neighborhood environments. © The Author(s) 2017.

Baier recently published an interesting original article in the Journal of Interpersonal Violence. He compared violent behavior (VB) between Christians and Muslims and concluded that religiosity was not a protecting factor against violence and that Muslim religiosity associated positively with increased VB. We appreciate the author's enormous efforts on researching such an issue of relevance to today's world. However, in our view, the article has methodological weaknesses in terms of participants, instruments, and statistical analyses, which we examine in detail. Therefore, Baier's results should be interpreted more cautiously. Although interpersonal violence may sometimes be observable among Muslims, we do not attribute these to Islam's teachings. In our opinion, both Islam and Christianity invite to tolerance, peace, and friendship. So, the comparison of such differences and the drawing of conclusions that may reflect negatively on specific religious groups need better defined research, taking into consideration other basic variables in different communities. © The Author(s) 2014.

Epidemiologists are increasingly using natural effects for applied mediation analyses, yet 1 key identifying assumption is unintuitive and subject to some controversy. In this issue of the Journal, Jiang and VanderWeele (Am J Epidemiol. 2015;182(2):105-108) formalize the conditions under which the difference method can be used to estimate natural indirect effects. In this commentary, I discuss implications of the controversial "cross-worlds" independence assumption needed to identify natural effects. I argue that with a binary mediator, a simple modification of the authors' approach will provide bounds for natural direct and indirect effect estimates that better reflect the capacity of the available data to support empirical statements on the presence of mediated effects. I discuss complications encountered when odds ratios are used to decompose effects, as well as the implications of incorrectly assuming the absence of exposure-induced mediator-outcome confounders. I note that the former problem can be entirely resolved using collapsible measures of effect, such as risk ratios. In the Appendix, I use previous derivations for natural direct effect bounds on the risk difference scale to provide bounds on the odds ratio scale that accommodate 1) uncertainty due to the cross-world independence assumption and 2) uncertainty due to the cross-world independence assumption and the presence of exposure-induced mediator-outcome confounders. © The Author 2015.

This invited commentary seeks to encourage a critical dialogue about youth homelessness that might assist in re-energizing a field that seems increasingly stagnant with a research body focused primarily on analyses of risk, hopelessly inadequate policy frameworks in most cities, diminishing funds for services, and decreasing media attention. Reviewing major trends in research and public responses to youth homelessness in the past century, I propose that there exist three major culturally-bound dimensions from which we construct our understanding of and responses to youth homelessness. These dimensions, which are considered in a transactional framework, are the scope of responsibility, the location of moral responsibility, and the amount of agency attributed to the youth. In this review I highlight the manner in which our historically binary and uncritical understanding of these dimensional characterizations of youth homelessness has led to major lapses in the effectiveness of our collective efforts to address this problem. I highlight gaps in the existing body of research literature and provide this framework, arguing that a strategic and cohesive response is vital if we are to move from reiterations of risk and hackneyed calls for prevention strategies to the generation of meaningful solutions.

Estimating the independent effect of "place" on health outcomes has proven quite difficult. In this issue of the Journal, Auchincloss and Diez Roux contribute a lucid introduction to agent-based simulation models and argue that they may be a fruitful alternative to current approaches to the problem. Insofar as conceptual understanding must precede empirical investigation, this author agrees. Given the obvious shortcoming of pure simulations, the key benefit of agent-based models lies in their ability to alter our thinking and/or theory. Among other things, the approach permits analysts to model (i.e., conceptualize) system dynamics, more realistic social treatment effects, endogenous contexts, and a more congenial image of human behavior.

The limitations of examining mediating factors by adjusting for them in standard regression models have been well-documented in the literature. Although alternative analytic models have been suggested, they are rarely used. In the accompanying article, Mumford et al. (Am J Epidemiol. 2010;173(2):145-156) use marginal structural linear mixed models to determine the association between dietary fiber intake and cholesterol through pathways that do not involve estradiol. Their findings suggest that overall high fiber intake decreases levels of total and low density lipoprotein (LDL) cholesterol and that there are multiple pathways through which fiber can act. The estradiol-mediated pathway seems to lead to increases in total and LDL cholesterol which are more than counterbalanced by pathways leading to decreases in total and LDL cholesterol. In addition to answering a scientifically interesting question, this work provides a concrete example of the use of marginal structural models for examination of direct effects and may serve as a guide to future researchers.

Sensors are an essential component of most electronic systems in the car. They deliver input parameters for comfort features, engine and emission control as well as for the active and passive safety systems. New technologies such as silicon micromachining play an important role for the introduction of these sensors in all vehicle classes. The importance and use of these sensor technologies in today"s automotive applications will be shown in this article. Finally an outlook on important current developments and new functions in the car will be given.

Electronic equipment is indispensable in modern motor cars for active and passive safety, exhaust and consumption monitoring or comfort. Electric and electronic systems today account for nearly 20 percent of the production cost of a normal passenger car, with an upward trend. Infotainment equipment is a growing market, which gets center stage in this issue. Further subjects discussed are current electronic and mechatronic applications as well as new developments in data transmission, development tools and constructional elements. [German] Ohne Elektronik sind moderne Automobile nicht mehr vorstellbar. Ob aktive oder passive Sicherheit, Abgas, Verbrauch oder Komfort - der Fortschritt im Autombil ist eng verknuepft mit der Einfuehrung neuer elektronischer Systeme und Komponenten. Obwohl meist nicht sehr auffaellig in einer Black-box verpackt, liegen die anteiligen Herstellungskosten fuer die Elektrik und Elektronik bei einem Mittelklassefahrzeug schon bei knapp 20 Prozent. Tendenz: Weiter steigend. Waehrend die Segnungen von ABS, ESP oder Motormanagement fuer den Kunden unsichtbar bleiben, tritt die Elektronik mit den Infotainment-Systemen ins Rampenlicht. Hochwertige Audio-Anlagen im Doppel-DIN-Format und grosse Farbbildschirme sitzen an prominenter Stelle im Armaturenbrett. Elektronische Systeme werden damit fuer den Kunden sichtbar, greifbar und erlebbar. Doch je mehr Funktionen integriert werden, desto wichtiger wird eine einfache Bedienung, die den Fahrer moeglichst wenig vom Verkehrsgeschehen ablenkt. Das ist leider keine Selbstverstaendlichkeit: Eine klare, einfache Bedienung wurde in der Vergangenheit schon bei so manchem simplen Cassetten-Radio schmerzlich vermisst. Infotainment im Automobil ist ein Wachstumsmarkt - und das Schwerpunkt-Thema der vorliegenden zweiten Ausgabe von 'Automotive Electronics'. Darueber hinaus beschaeftigt sich auch diese Ausgabe mit aktuellen Elektronik- und Mechatronik-Anwendungen und berichtet ueber neue Entwicklungen

Social media-based recruitment for epidemiologic studies has the potential to expand the demographic and geographic reach of investigators and identify potential participants more cost-effectively than traditional approaches. In fact, social media are particularly appealing for their ability to engage traditionally "hard-to-reach" populations, including young adults and low-income populations. Despite their great promise as a tool for epidemiologists, social media-based recruitment approaches do not currently compare favorably with gold-standard probability-based sampling approaches. Sparse data on the demographic characteristics of social media users, patterns of social media use, and appropriate sampling frames limit our ability to implement probability-based sampling strategies. In a well-conducted study, Harris et al. (Am J Epidemiol. 2015;181(10):737-746) examined the cost-effectiveness of social media-based recruitment (advertisements and promotion) in the Contraceptive Use, Pregnancy Intention, and Decisions (CUPID) Study, a cohort study of 3,799 young adult Australian women, and the approximate representativeness of the CUPID cohort. Implications for social media-based recruitment strategies for cohort assembly, data accuracy, implementation, and human subjects concerns are discussed. © The Author 2015.

There is no complete solution for the problem of abuse of statistics, but methodological training needs to cover cognitive biases and other psychosocial factors affecting inferences. The present paper discusses 3 common cognitive distortions: 1) dichotomania, the compulsion to perceive quantities as dichotomous even when dichotomization is unnecessary and misleading, as in inferences based on whether a P value is "statistically significant"; 2) nullism, the tendency to privilege the hypothesis of no difference or no effect when there is no scientific basis for doing so, as when testing only the null hypothesis; and 3) statistical reification, treating hypothetical data distributions and statistical models as if they reflect known physical laws rather than speculative assumptions for thought experiments. As commonly misused, null-hypothesis significance testing combines these cognitive problems to produce highly distorted interpretation and reporting of study results. Interval estimation has so far proven to be an inadequate solution because it involves dichotomization, an avenue for nullism. Sensitivity and bias analyses have been proposed to address reproducibility problems (Am J Epidemiol. 2017;186(6):646-647); these methods can indeed address reification, but they can also introduce new distortions via misleading specifications for bias parameters. P values can be reframed to lessen distortions by presenting them without reference to a cutoff, providing them for relevant alternatives to the null, and recognizing their dependence on all assumptions used in their computation; they nonetheless require rescaling for measuring evidence. I conclude that methodological development and training should go beyond coverage of mechanistic biases (e.g., confounding, selection bias, measurement error) to cover distortions of conclusions produced by statistical methods and psychosocial forces. © The Author(s) 2017.

In a cross-sectional study among 953 young Danish men (2008-2011), Jensen et al. reported that sleep disturbances showed inverse U-shaped associations with semen parameters and testis size (Am J Epidemiol. 2013;177(10):1027-1037). Sleep disturbances were associated with several factors likely to affect semen parameters (such as history of sexually transmitted infections) that cannot all be efficiently controlled for, leaving room for residual confounding. Future studies could adopt a longitudinal design and rely on objective personal measures of sleep quality and duration using accelerometers. Intervention studies would also be helpful to identify whether sleep disturbances (or improvement of sleep quality) can lead to short-term variations in semen parameters. This study adds another suspect to the list of factors possibly influencing male fecundity potential, which also includes overweight, exposure to tobacco smoke (in adulthood and in utero), exposure to specific persistent (lead, organic pollutants) and nonpersistent (some phthalates, bisphenol A) environmental pollutants, and exposure to atmospheric pollutants. Even if each of these factors has a weak impact at the individual level, the large number of factors and the relatively high prevalence of exposure in the general population make it likely that at the population level, lifestyle and environmental factors put a high burden on male fecundity potential.

Increasing complexity and performance and reliability expectations make modeling of automotive system both more difficult and more urgent. Automotive control has slowly evolved from an add-on to classical engine and vehicle design to a key technology to enforce consumption, pollution and safety limits. Modeling, however, is still mainly based on classical methods, even though much progress has been done in the identification community to speed it up and improve it. This book, the product of a workshop of representatives of different communities, offers an insight on how to close the gap and exploit this progress for the next generations of vehicles.

Hydrogen fueled vehicles may just be the answer to the air pollution problem in highly polluted urban environments where the innovative vehicle's air pollution abatement characteristics would justify its high operating costs as compared with those of conventional automotive alternatives. This paper examines the feasibility of hydrogen as an automotive fuel by analyzing the following aspects: the chemical-physical properties of hydrogen in relation to its use in internal combustion engines; the modifications necessary to adapt internal combustion engines to hydrogen use; hydrogen fuel injection systems; current production technologies and commercialization status of hydrogen automotive fuels; energy efficiency ratings; environmental impacts; in-vehicle storage systems - involving the use of hydrides, high pressure systems and liquid hydrogen storage systems; performance in terms of pay-load ratio; autonomous operation; and operating costs. With reference to recent trial results being obtained in the USA, an assessment is also made of the feasibility of the use of methane-hydrogen mixtures as automotive fuels. The paper concludes with a review of progress being made by ENEA (the Italian Agency for New Technology, Energy and the Environment) in the development of fuel storage and electronic fuel injection systems for hydrogen powered vehicles

This commentary on Zhong et al. begins by addressing the definition of remorse. It then primarily focuses on the relation between remorse and various justifications for punishment commonly accepted in Anglo-American jurisprudence and suggests that remorse cannot be used in a principled way in sentencing. It examines whether forensic psychiatrists have special expertise in evaluating remorse and concludes that they do not. The final section is a pessimistic meditation on sentencing disparities, which is a striking finding of Zhong et al.

Full Text Available The paper presents a historical analysis of tendencies pertaining to automotive evolution. It has been shown how motivation to higher speed and capacity had made it possible to manufacture automobiles with several hundred horsepower capacity. Traffic speed in the cities is rather less than technical capabilities of automobiles; there are serious ecological and traffic safety problems. Solution of serious traffic safety problems is possible only while developing clever automobiles for clever traffic roads within the framework of intelligent transportation systems.

An assessment of the technical/economic feasibility of the use of hydrogen as an automotive fuel is made based on analyses of the following: the chemical- physical properties of hydrogen in relation to its use in internal combustion engines; the modifications necessary to adapt internal combustion engines to hydrogen use; hydrogen fuel injection systems - with water vapour injection, cryogenic injection, and the low or high pressure injection of hydrogen directly into the combustion chamber; the current commercialization status of hydrogen automotive fuels; energy efficiency ratings; environmental impacts; in-vehicle storage systems - involving the use of hydrides, high pressure systems and liquid hydrogen storage systems; performance in terms of pay-load ratio; autonomous operation; and operating costs. The paper concludes that, considering current costs for hydrogen fuel production, distribution and use, at present, the employment of hydrogen fuelled vehicles is feasible only in highly polluted urban environments where the innovative vehicle's air pollution abatement characteristics would justify its high operating costs as compared with those of conventional automotive alternatives

Full Text Available This commentary offers a review of Ohriner's corpus-based research on rap music, and includes an in-depth comparison of Ohriner's model with my own. It highlights multiple divergences in our underlying methodologies, and outlines the potential impact of such differences on the research results. Ohriner provides a convincing and widely appealing presentation of how musical corpora may be leveraged to effectively enhance traditional forms of analysis. However, I question his approach to certain processes, such as sampling, transcription, and segmentation. I believe that his analysis would benefit from stronger definitions in these areas.

The automotive optical engineer has an entirely new set of rules to follow for a 'smooth lighted appearance' with the introduction of LEDs into the automotive signal lighting market. To move away from the 'polka-dot' appearance long associated with the usage of LEDs as the light source for automotive lighting, and give the consumer a smooth lighted appearance to his lamp, there are several optical parameters that must be observed. The number and type of LEDs used, the size of the optical elements used, the spacing of the optical elements, plus many other factors all play a critical role and must be considered in the solution to the 'smooth lighted appearance' in an automotive signal lamp. The 'smooth lighted appearance' in an automotive signal lamp has long been a difficult problem to which there is more than one solution. The most visually pleasing and effective solution is not always the most easily obtainable solution since photometry requirements and smooth lighted appearance can be diametric goals. Subsequently the most cost effective and the easily 'doable' solution may not give the ultimate in aesthetically pleasing results for the consumer. Therefore, it is the purpose and intent of this paper to outline the parameters that need to be considered to obtain a 'smooth lighted appearance' for an automotive signal lamp, and to clarify the methods and 'tools' that are required to meet this goal.

- Automotive sensors are used for emission gas purification, energy conservation, car kinematic performance, safety and ITS (intelligent transportation system). The comparison of the sensor characteristics was made for their application area. Many kinds of the principles are applied for the sensors. There are two types of sensors, such as physical and chemical one. Many of the automotive sensors are physical type such as mechanical sensors. And a gas sensor is a chemical type. The sensors have been remarkably developed with the advancement of the MEMS (Micro Electro Mechanical Systems) technology. In this paper, gas, pressure, combustion pressure, acceleration, magnetic, and angular rate sensors for automotive use are explained with their features. The sensors are key devices to control cars in the engine, power train, chassis and safety systems. The environment resistance, long term reliability, and low cost are required for the automotive sensors. They are very hard to be resolved. However, the sensor technology contributes greatly to improving global environment, energy conservation, and safety. The applications of automotive sensors will be expanded with the automobile developments.
For at least the remainder of this century, the United States faces a growing dependence on imported oil. Costs are substantial, and they will mount. In June 1992, net imports provided nearly 50% of supplies, and their cost was $4.3 billion. Cost of net imports of motor vehicles and parts amounted to $3.0 billion. The two items combined totaled more than the negative trade balance of $6.6 billion. The light-duty highway fleet alone accounted for 38.2% of U.S. oil consumption in 1988. Correspondingly, the fleet was a substantial emitter of air pollutants - NO x , CO, and nonmethane hydrocarbons. In addition, it was a major source of CO 2 . The twin problems of oil imports and pollution would be ameliorated if the fuel economy if cars and trucks could be improved and their emissions were also reduced. In principle, the mileage of US automobiles could be substantially improved. But on purchasing a car, U.S. buyers rank fuel efficiency eight when making their choice. They are attracted to options that lower mileage. Consumers also tend to prefer large cars over small ones for reasons of safety. Increasingly, buyers are purchasing light trucks and vans that have inferior fuel efficiency. As a result of the above trends, the average mileage of the US automotive fleet has been diminishing. As long as fuel is available at comparatively low prices and there is no federal requirement for better mileage, improvement is unlikely. Moreover, even if improvements were mandated, change would be slow

Commentary driving typically involves being trained in how to produce a verbal running commentary about what you can see, what you are doing, what might happen and what action you will take to avoid potential hazards, while driving. Although video-based commentary training has been associated with subsequent hazard perception improvements, it can have a negative impact on hazard perception when a live commentary is produced at test (Young, Chapman, & Crundall, 2014). In the current study we use balanced training and testing blocks to isolate the effects of commentary exposure, production of a commentary with and without practice, and learning from earlier self-generation of commentary on behavioural and eye movement measures. Importantly, both commentary exposed and unexposed groups gave hazard perception responses during the commentary video, ensuring that the unexposed control group remained engaged in the procedure throughout. Results show that producing a live commentary is detrimental to concurrent hazard perception, even after practice, and does not enhance any later effect of commentary exposure. Although commentary exposure led to an initial increase in the accuracy of hazard perception responses, this effect was limited to the first occasion of testing, and showed no later benefits relative to engaged hazard exposure.

Full Text Available The car industry uses a tremendous number of materials to build cars, including iron, aluminum, steel, glass, rubber, petroleum products, copper, steel and others. These materials have evolved greatly over the decades, becoming more sophisticated, better built, and safer. They've changed as new automotive manufacturing technologies have emerged over the years, and they're used in increasingly innovative ways. This article is devoted to systematization information on the introduction and application of modern materials in the automotive industry. Given both domestic and foreign sources of information, it follows that car manufacturers are constantly pushing to create the lightest cars possible to increase speed and power. Research and development into lightweight materials is essential for lowering their cost, increasing their ability to be recycled, enabling their integration into vehicles, and maximizing their fuel economy benefits. Light weighting without loss of strength and speed properties is the present, and the future, of the automotive manufacturing industry. It brings innovative materials to the frontline of design.

Considerable fuel energy, as much as 70%, is not converted to useful work by internal combustion engines but is instead rejected as waste heat, and more than half of the waste heat, nearly 40% of fuel energy, is contained in vehicle exhaust gas. This provides an opportunity to recover some of the wasted fuel energy and convert it from heat into useful work, subject to the laws of thermodynamics, and thereby improve vehicle energy efficiency. Thermoelectric (TE) materials have been extensively researched and TE devices are now being developed for operation at high temperatures corresponding to automotive exhaust gases for direct solid-state conversion of heat into electricity. This has stimulated substantial progress in the development of practical TE generator (TEG) systems for large-scale commercialization. A significant enabler of this progress has been the US Department of Energy's Vehicle Technologies Program through funding for low cost solutions for automotive TE waste heat recovery to improve fuel economy. Our current project at General Motors has culminated in the identification of the potential supply chain for all components and assembly of an automotive TEG. A significant focus has been to develop integrated and iterative modeling tools for a fully optimized TEG design that includes all components and subsystems (TE modules, heat exchangers, thermal interfaces, electrical interconnects, power conditioning, and vehicle integration for maximal use of TEG power). We have built and tested a new, low-cost Initial TEG prototype based on state-of-the-art production-scale skutterudite TE modules, novel heat exchanger designs, and practical solutions to the many technical challenges for optimum TEG performance. We will use the results for our Initial TEG prototype to refine our modeling and design tools for a Final automotive TEG system prototype. Our recent results will be presented. Thanks to: J.R.

Full Text Available Alf Hornborg says many useful things in his article, Ecosystems and World Systems: Accumulation as an Ecological Process. His effort to ground the notion of capital accumulation in the physical realities of ecology and thermodynamics is a much-needed corrective to nature-blind studies of capitalism. At a more paradigmatic level, his dismay at the analytical disjuncture of ecology and economics in modern social science is right on target (1998: 169. Yet, despite the articles laudable intent, Hornborg goes astray by imputing to Marx a focus on labor that excludes the physical realities of labor reproduction, world trade, or imperialism. Hornborg is right to urge a synthesis of ecological and economic studies, but wrong in his call to supplement the labor theory of value with a resource-oriented concept of exploitation (1998: 173. Even if Marx did not grapple with a global ecological crisis of contemporary standards, he was remarkably sensitive to ecological processes as they shaped, and were shaped by, capital accumulation; indeed, Marx studied intensively the works of the leading soil chemists of his day, foremost among them Justus von Liebig. Particularly in the ?rst and third volumes of Capital, Marx provides a compelling framework for comprehending the nature-society dialectic under capitalism.

Full Text Available Measurement of temperatures in engine and exhaust systems in automotive applications is necessary for thermal protection of the parts and optimizing of the combustion process. State-of-the-art temperature sensors are very limited in their response characteristic and installation space requirement. Miniaturized sensor concepts with a customizable geometry are needed. The basic idea of this novel sensor concept is to use thick-film technology on component surfaces. Different standardized and especially nonstandard material combinations of thermocouples have been produced for the validation of this technology concept. Application-oriented measurements took place in the exhaust system of a test vehicle and were compared to standard laboratory conditions.

This paper presents a set of parametric studies performed on automotive radiators by means of a detailed rating and design heat exchanger model developed by the authors. This numerical tool has been previously verified and validated using a wide experimental data bank. A first part of the analysis focuses on the influence of working conditions on both fluids (mass flows, inlet temperatures) and the impact of the selected coolant fluid. Following these studies, the influence of some geometrical parameters is analysed (fin pitch, louver angle) as well as the importance of coolant flow lay-out on the radiator global performance. This work provides an overall behaviour report of automobile radiators working at usual range of operating conditions, while significant knowledge-based design conclusions have also been reported. The results show the utility of this numerical model as a rating and design tool for heat exchangers manufacturers, being a reasonable compromise between classic ε - NTU methods and CFD

There exists already a market of bio-automotive fuels i.e. bioethanol and biodiesel produced from food crops in many countries. From the viewpoint of economics, environment, land use, water use and chemical fertilizer use, however, there is a strong preference for the use of woody biomass and various forest/agricultural residues as the feedstock. Thus, the production of 2nd generation of bio-automotive fuels i.e. synthetic fuels such as methanol, ethanol, DME, FT-diesel, SNG and hydrogen through biomass gasification seems promising. The technology of producing synthetic fuels is well established based on fossil fuels. For biomass, however, it is fairly new and the technology is under development. Starting from the present market of the 1st generation bio-automotive fuels, this paper is trying to review the technology development of the 2nd generation bio-automotive fuels from syngas platform. The production of syngas is emphasized which suggests appropriate gasifier design for a high quality syngas production. A number of bio-automotive fuel demonstration plant will be presented, which gives the state of the art in the development of BTS (biomass to synthetic fuels) technologies. It can be concluded that the 2nd generation bio-automotive fuels are on the way to a breakthrough in the transport markets of industrial countries especially for those countries with a strong forest industry.

In this issue of the Journal, Jokela et al. (Am J Epidemiol. 2013;178(5):667-675) scrutinize the association between personality phenotype and all-cause mortality in remarkable detail by using an "individual-participant meta-analysis" design. Across 7 large cohorts varying in demographics and methods of personality measurement, they find varying prospective associations for 4 dimensions of the five-factor (or "Big Five") model of personality, but robust and consistent prospective associations for Big Five dimension of "conscientiousness." Jokela et al. place an important exclamation point on a long era of study of this topic and hint directly and indirectly at new avenues for this line of research. I consider the following 3 areas particularly rife for further inquiry: the role of genetics in personality and health studies; the role of personality in social inequalities in health; and the health policy and clinical implications of work like that of Jokela et al., including the potential role of personality phenotype in the evolution of personalized medicine.

Approximately 15% of all couples are unable to conceive after a year and are labeled infertile. In recent years, increasing attention has been given to lifestyle factors that may impact fertility. In the United States, it is estimated that there are more than 17 million current users of marijuana with 4.6 million using marijuana almost daily. Although common, to date, little data exist on the impact of marijuana use on male fertility. In the current issue of the Journal, Gundersen et al. (Am J Epidemiol. 2015;182(6):473-481) provide data examining the relationship between marijuana use and semen quality from young men recruited out of the general Danish population. Men who reported daily marijuana use displayed significant lower sperm concentration and sperm counts compared with nonusers, while testosterone levels were higher. The current report provides important information for patients and providers regarding the negative association of marijuana use on semen quality. Although the benefit of marijuana cessation on recovery is uncertain, further study on the impact of marijuana use on male reproductive health is warranted as more states explore marijuana legalization. © The Author 2015.

Over the past decade, leading epidemiologists have noted the importance of social factors in studying and understanding the distribution and determinants of disease in human populations; but to what extent are epidemiologic studies integrating genetic information and other biologic variables with information about individual-level risk factors and group-level or societal factors related to the broader residential, behavioral, or cultural context? There remains a need to consider ways to integrate genetic information with social and contextual information in epidemiologic studies, partly to combat the overemphasis on the importance of genetic factors as determinants of disease in human populations. Even in genome-wide association studies of coronary heart disease and other common complex diseases, only a small proportion of heritability is explained by the genetic variants identified to date. It is possible that familial clustering due to genetic factors has been overestimated and that important environmental or social influences (acting alone or in combination with genetic variants) have been overlooked. The accompanying article by Bressler et al. (Am J Epidemiol. 2010;171(1):14-23) highlights some of these important issues.

Almost 40 years ago, Berkman and Syme demonstrated that social networks were related to the risk of early mortality (Am J Epidemiol. 1979;109(2):186-204). Their study was highly innovative because they directly measured and quantified social networks in a large prospective population-based survey with mortality follow-up. The results of the study showed robust network gradients, whereby those with fewer networks and weaker social ties had significantly higher mortality rates. The important influence of social networks that Berkman and Syme noted many years ago is likely to heighten in the future, as demographic characteristics shift and individuals become more inclined to socialize through online platforms instead of real-world interactions. Berkman and Syme's research in 1979 continues to play a key role in shaping recent efforts to uncover the influence of social networks on health. Looking back on their findings may help epidemiologists better understand the importance of both online and offline networks for population health today. © The Author 2017.

The prevalence of childhood and adolescent obesity has tripled in the past three decades. This increase has been accompanied by a dramatic rise in obesity-related health complications among American youth. Thus, many obese youth are now experiencing illnesses that will threaten their life expectancy in the absence of significant weight loss. Despite these concerns, a relatively modest body of research has focused on the treatment of adolescent obesity. Results from trials investigating the efficacy of behavioral and pharmacological treatments, like studies of these interventions with adults, suggest that individuals typically lose 5-10% of their initial weight. Unfortunately, weight regain is common. Given the increase in the number of obese adolescents, coupled with the modest results from more conservative treatment approaches, it is not surprising that bariatric surgery for adolescents who suffer from extreme obesity has grown in popularity. The weight losses after surgery are impressive and many adolescents, like adults, experience significant improvements in their physical and mental health postoperatively. However, only a small fraction of adolescents and adults who are heavy enough for bariatric surgery present for surgical treatment. Among those who undergo surgery, a significant minority appear to struggle with a number of behavioral and psychosocial issues that threaten their lifelong success. With all of this in mind, the current obesity problem in the United States and other Westernized countries likely will present a significant challenge to both current and future medical and mental health professionals who work with adolescents and young adults.
Although it is well established that a having a pregnancy that ends in a birth protects against subsequent preeclampsia, it is unclear whether a pregnancy ending in miscarriage or induced abortion confers any protection. In this issue of the Journal, Parker et al. (Am J Epidemiol. 2015;182(8):663-669) examine whether, in nulliparous women, a history of induced abortion is associated with a lower risk of preeclampsia in a later pregnancy, focusing on the hypothesis that endometrial injury facilitates later implantation. The authors take advantage of data obtained by linking several Finnish population-based registries that include detailed data on induced abortions, although information on miscarriages was of lower quality. Parker et al. found a modest reduction in risk among women with a history of induced abortion. However, there was little evidence that risk differed between women who had medical abortions and those who had surgical abortions (the latter of which is presumably associated with a higher degree of injury). History of miscarriage was not associated with preeclampsia risk. Although the study by Parker et al. adds to the evidence that suggests that women with a history of induced abortion have a lower risk of preeclampsia, it is difficult to evaluate whether the observed association is due to having had a previous pregnancy (however short) versus none, to confounding, or to an actual effect of induced abortion. © The Author 2015.

Anal cancer is common among people infected with human immunodeficiency virus (HIV). This cancer is caused by human papillomavirus, and immunosuppression likely contributes to its development. In this issue of the Journal, Bertisch et al. (Am J Epidemiol. 2013;178(6):877–884) present the results of a case-control study of anal cancer among HIV-infected people in Switzerland. They demonstrate that anal cancer risk is increased in association with a low CD4+ cell count (a clinical measurement of immune status). In particular, HIV-induced immunosuppression was most severe among cases approximately 6–7 years prior to the diagnosis of anal cancer. A plausible biological interpretation is that immunosuppression is important at an early stage of the development of anal cancer, but that the neoplastic process becomes irreversible over time with persistent human papillomavirus infection and genetic damage. With current efforts to provide earlier combination antiretroviral therapy to HIV-infected people, anal cancer incidence may start to decline. Bertisch et al. also demonstrate a strong association between serum antibodies against the human papillomavirus type 16 protein E6 and anal cancer risk, highlighting the role of this viral oncoprotein in carcinogenesis. Additional biomarkers could help refine clinical approaches to anal cancer screening and prevention for the HIV-infected population. PMID:23900552

The acquired immune deficiency syndrome (AIDS) epidemic was first recognized in 1981, and it quickly became a public health emergency. In a 1987 paper in the American Journal of Epidemiology (Am J Epidemiol. 1987;126(2): 310-318), Richard Kaslow et al. described the launch of the Multicenter AIDS Cohort Study (MACS), a cohort study of homosexual men in 4 US cities, the purpose of which was to better understand the natural history of AIDS and its determinants. The MACS enrolled participants through a range of community contacts. These efforts facilitated rapid recruitment, but given the targeted approaches, participants tended to comprise high-risk social networks. At baseline, 4%-26% of participants at the 4 sites reported having a sexual partner who had developed AIDS. Kaslow et al. also described baseline testing for the causative agent of AIDS, the human immunodeficiency virus (HIV). HIV seroprevalence was remarkably high, ranging from 11%-26% across age groups in Pittsburgh to 38%-53% in Los Angeles. The major turning point in the epidemic occurred in 1995-1996 when combination antiretroviral therapy was introduced, effectively blocking HIV replication and markedly reducing AIDS morbidity and mortality. The MACS cohort continues to be followed actively 3 decades after its launch and has proven to be an important resource for information on HIV infection and AIDS.

Complexities of both definition and dynamics suggest that the unit of analysis in research on homelessness may need rethinking. Wright and Devine's corrective effort can be criticized on the grounds that it inflates the shortcomings of the admittedly flawed 1990 S-Night count, applies relative proportions from an unrepresentative local sample, and smuggles in an overly inclusive notion of homelessness.
Straw, R B
Many of criticisms of the Census Bureau's S-Night count of the homeless advanced by Wright and Devine are appropriate. However, a more important issue--the lack of agreement in the field on an appropriate conceptual definition of homelessness--undermines their overall critique.

Population health improvements are the most relevant yardstick against which to evaluate the success of social epidemiology. In coming years, social epidemiology must increasingly emphasize research that facilitates translation into health improvements, with continued focus on macro-level social determinants of health. Given the evidence that the effects of social interventions often differ across population subgroups, systematic and transparent exploration of the heterogeneity of health determinants across populations will help inform effective interventions. This research should consider both biological and social risk factors and effect modifiers. We also recommend that social epidemiologists take advantage of recent revolutionary improvements in data availability and computing power to examine new hypotheses and expand our repertoire of study designs. Better data and computing power should facilitate underused analytic approaches, such as instrumental variables, simulation studies and models of complex systems, and sensitivity analyses of model biases. Many data-driven machine-learning approaches are also now computationally feasible and likely to improve both prediction models and causal inference in social epidemiology. Finally, we emphasize the importance of specifying exposures corresponding with realistic interventions and policy options. Effect estimates for directly modifiable, clearly defined health determinants are most relevant for building translational social epidemiology to reduce disparities and improve population health.

Full Text Available In recent years, the automotive industry has known a remarkable development in order to satisfy the customer requirements. In this paper, we will study one of the components of the automotive which is the twist beam. The study is focused on the multicriteria design of the automotive twist beam undergoing linear elastic deformation (Hooke׳s law. Indeed, for the design of this automotive part, there are some criteria to be considered as the rigidity (stiffness and the resistance to fatigue. Those two criteria are known to be conflicting, therefore, our aim is to identify the Pareto front of this problem. To do this, we used a Normal Boundary Intersection (NBI algorithm coupling with a radial basis function (RBF metamodel in order to reduce the high calculation time needed for solving the multicriteria design problem. Otherwise, we used the free form deformation (FFD technique for the generation of the 3D shapes of the automotive part studied during the optimization process.

This book demonstrates the use of the optimization techniques that are becoming essential to meet the increasing stringency and variety of requirements for automotive systems. It shows the reader how to move away from earlier approaches, based on some degree of heuristics, to the use of more and more common systematic methods. Even systematic methods can be developed and applied in a large number of forms so the text collects contributions from across the theory, methods and real-world automotive applications of optimization. Greater fuel economy, significant reductions in permissible emissions, new drivability requirements and the generally increasing complexity of automotive systems are among the criteria that the contributing authors set themselves to meet. In many cases multiple and often conflicting requirements give rise to multi-objective constrained optimization problems which are also considered. Some of these problems fall into the domain of the traditional multi-disciplinary optimization applie...

As compared to petroleum diesel, biodiesel is more corrosive for automotive materials. Studies on the characterization of corrosion products of fuel exposed automotive materials are scarce. Automotive fuel system and engine components are made from different ferrous and non-ferrous materials. The present study aims to investigate the corrosion products of different types of automotive materials such as copper, brass, aluminum and cast iron upon exposure to diesel and palm biodiesel. Changes in fuel properties due to exposure of different materials were also examined. Degradation of metal surface was characterized by digital camera, SEM/EDS and X-ray diffraction (XRD). Fuel properties were examined by measuring TAN (total acid number), density and viscosity. Among the metal investigated, copper is found to be least resistant in biodiesel and formed comparatively more corrosion products than other metals. Upon exposure of metals in biodiesel, TAN number crosses the limit given by standard while density and viscosity remain within the acceptable range of limit. -- Highlights: ► Order of incompatible metals in palm biodiesel: copper > brass > aluminum > cast iron. ► The possible reactions for the degradation of copper and cast iron have been discussed. ► For metal exposed biodiesel, only TAN number crosses the limit while density and viscosity remain within the limit. ► Copper and copper based alloy (brass) increase TAN number comparatively more than other metals.

The capital trial, by its nature, is fraught with emotionally disturbing elements that jurors must face when deciding the ultimate fate of a guilty defendant. A confluence of mitigating and aggravating factors influences a capital jury's decision to impose a sentence of death. The presence or absence of defendant remorse in these cases may make all the difference in whether a capital defendant's life is spared. This commentary examines the onerous emotional toll encountered by capital jurors in light of the findings of Corwin and colleagues regarding defendant remorse and juror's need for affect. The commentary also presents practical and ethics-related considerations that should be kept in mind when reflecting on their study.

Recently, improvement in fuel efficiency and safety has become the biggest issue in worldwide automotive industry. Although the regulation of environment and safety has been tightened up more and more, the majority of vehicle bodies are still manufactured from stamped steel components. This means that the optimized steel solutions enable to demonstrate its ability to reduce body weight with high crashworthiness performance instead of expensive light weight materials such as Al, Mg and composites. To provide the innovative steel solutions for automotive industry, POSCO has developed AHSS and its application technologies, which is directly connected to EVI activities. EVI is a technical cooperation program with customer covering all stages of new car project from design to mass production. Integrated light weight solutions through new forming technologies such as TWB, hydroforming and HPF are continuously developed and provided for EVI activities. This paper will discuss the detailed status of these technologies especially light weight steel solutions based on innovative technologies.

The automotive industry has used computational methods for crashworthiness since the early 1970's. These methods have ranged from simple lumped parameter models to full finite element models. The emergence of the full finite element models in the mid 1980's has significantly altered the research direction. However, there remains a need for both simple, rapid modeling methods and complex detailed methods. Some directions for continuing research are discussed.

Studies on occupational skin diseases in workers of the automotive industry are few. To investigate the prevalence of occupational skin diseases in workers of the automotive industry. Between September and December 2011, a total of 405 workers from the automotive repair industry in Diyarbakır were interviewed. They were active workers in the repair industry who had been employed for at least six months. Business owners, sellers of spare parts and accounting officers were not included. The employees were examined at their workplaces and the working conditions were observed. Detailed dermatological examination was performed. The mean age of the 405 workers who participated in the study was 27.7 ± 10.3. The mean working time of employees was 13.3 ± 10.4 years. All of the employees were male. Dermatological diseases were not detected in 144 out of 405 workers (35.6%) and at least one condition was diagnosed in 261 (64.4%). The most frequent diagnosis was callus, hyperkeratosis, clavus (27.7%), followed by nail changes (16.8%) and superficial mycoses (12.1%). Contact dermatitis was seen at a rate of 5.9%. Traumatic lesions such as hyperkeratotic lesions and nail changes were found most frequently. Traumatic lesions were common among individuals who did not use gloves. Most nail changes were localized leuconychia, a finding not reported in the studies on automotive industry workers. In accordance with the literature, irritant contact dermatitis was observed in patients with a history of atopy and who had been working for a long time. Occupational skin diseases comprise an important field in dermatology, deserving much attention. Further studies on occupational dermatology are necessary.

We have utilized the high brightness of state-of-the-art diode laser sources, and a variety of emerging optical technologies to develop a new class of thin, uniquely styled automotive brake and signal lamps. Using optics based on thin (5 mm) plastic sheets, these lamps provide appearance and functional advantages not attainable with traditional automotive lighting systems. The light is coupled into the sheets using a 1 mm diameter glass fiber, and manipulated using refraction and reflection from edges, surfaces, and shaped cut-outs. Light can be extracted with an efficiency of approximately 50% and formed into a luminance distribution that meets the Society of Automotive Engineers (SAE) photometric requirements. Prototype lamps using these optics have been constructed and are less than one inch in thickness. Thin lamps reduce sheet metal costs, complexity, material usage, weight, and allow for increased trunk volume. In addition, these optics enhance lamp design flexibility. When the lamps are not energized, they can appear body colored, and when lighted, the brightness distribution across the lamp can be uniform or structured. A diode laser based brake lamp consumes seven times less electrical power than one using an incandescent source and has instant on capability. Also, diode lasers have the potential to be 10-year/150,000 mile light sources.

This commentary describes the likely impacts on children's health and wellbeing from climate change, based on the solid science of environmental child health. It describes likely climate change scenarios, why children are more vulnerable than older people to these changes, and what to expect in terms of diseases (e.g., infections, asthma) and problems (e.g., malnutrition, mental illness). The common antecedents of climate change and other detrimental changes to our society mean that in combatting them (such as excessive consumption and greed), we may not only reduce the harmful effects of climate change but also work towards a better society overall-one that values its children and their futures.

This commentary discusses the intersection of human ovarian and somatic aging. It argues for re-contextualizing estrogen's role in and impact on ovarian aging and, more broadly, on women's health, considering in particular the importance of timing, dose, and the broader endocrine milieu. Distinguishing between current clinical needs and optimizing women's future options, the paper outlines an approach to broadening the research agenda to better understand the role of ovarian aging in supporting the metabolic demands of longevity. Three overarching issues important to consider explicitly as we pursue research on the health correlates of reproductive aging are discussed, including implications of a lifespan approach, population diversity, and selection bias.
A commentary is given on taxation aspects of the expenditure incurred in the abandonment and reclamation of oil and gas fields. Reference is made to the taxation regime in Australia, Canada, the Netherlands, Norway, the United Kingdom and the USA. The issues addressed include: specific provisions existing within the tax code covering abandonment; the definition of abandonment costs; the year in which deduction, if available, falls; the setting of deductions against any form of income; the allowance of deductions for costs which, under general principles, are capital costs; 'claw back' from reimbursements; the precision of a deduction for abandonment costs where a country has a secondary petroleum regime.

Introduction of new fuel economy, performance, safety, and comfort features in future automobiles will bring up many new, power-hungry electrical systems. As a consequence, demands on automotive batteries will grow substantially, e.g. regarding reliability, energy throughput (shallow-cycle life), charge acceptance, and high-rate partial state-of-charge (HRPSOC) operation. As higher voltage levels are mostly not an economically feasible alternative for the short term, the existing 14 V electrical system will have to fulfil these new demands, utilizing advanced 12 V energy storage devices. The well-established lead-acid battery technology is expected to keep playing a key role in this application. Compared to traditional starting-lighting-ignition (SLI) batteries, significant technological progress has been achieved or can be expected, which improve both performance and service life. System integration of the storage device into the vehicle will become increasingly important. Battery monitoring systems (BMS) are expected to become a commodity, penetrating the automotive volume market from both highly equipped premium cars and dedicated fuel-economy vehicles (e.g. stop/start). Battery monitoring systems will allow for more aggressive battery operating strategies, at the same time improving the reliability of the power supply system. Where a single lead-acid battery cannot fulfil the increasing demands, dual-storage systems may form a cost-efficient extension. They consist either of two lead-acid batteries or of a lead-acid battery plus another storage device.
In the current automobile market buffeting is one of the customer frequent complaints on luxury cars and SUVs. Buffeting is a low frequency but high level wind noise and makes people inside the vehicle uncomfortable if it lasts for a long period of time. The physical mechanism of buffeting is a complicated phenomenon of aeroacoustic resonance. The aeroacoustic characteristics of buffeting depend on vehicle features and operating conditions. In this paper, a survey of CFD studies on the automotive buffeting is presented. Firstly, several buffeting related concepts, such as Helmholtz resonator, flow over a cavity, shear layer instability and vortex shedding, are reviewed and relevant references are listed. Then, a historic survey of the buffeting investigation is made with emphasis on computational studies. As an example, the buffeting studies at DaimlerChrysler are selected to demonstrate the procedure of CFD simulation for automotive buffeting. The procedure is then validated by the correlation with wind tunnel testing. After that the validated procedure is applied to find solutions for buffeting reduction. Finally, some comments on buffeting studies are addressed. (author)

Around 40% of the total fuel energy in typical internal combustion engines (ICEs) is rejected to the environment in the form of exhaust gas waste heat. Efficient recovery of this waste heat in automobiles can promise a fuel economy improvement of 5%. The thermal energy can be harvested through thermoelectric generators (TEGs) utilizing the Seebeck effect. In the present work, a versatile test bench has been designed and built in order to simulate conditions found on test vehicles. This allows experimental performance evaluation and model validation of automotive thermoelectric generators. An electrically heated exhaust gas circuit and a circulator based coolant loop enable integrated system testing of hot and cold side heat exchangers, thermoelectric modules (TEMs), and thermal interface materials at various scales. A transient thermal model of the coolant loop was created in order to design a system which can maintain constant coolant temperature under variable heat input. Additionally, as electrical heaters cannot match the transient response of an ICE, modelling was completed in order to design a relaxed exhaust flow and temperature history utilizing the system thermal lag. This profile reduced required heating power and gas flow rates by over 50%. The test bench was used to evaluate a DOE/GM initial prototype automotive TEG and validate analytical performance models. The maximum electrical power generation was found to be 54 W with a thermal conversion efficiency of 1.8%. It has been found that thermal interface management is critical for achieving maximum system performance, with novel designs being considered for further improvement.

Simplifying the composition of the automotive HID lamp electronic ballast has been considered. This paper describes the novel electronic ballast that is composed of a DC/DC converter, a capacitor connected to a lamp in series, a switch (S3) connected to the capacitor in parallel, a switch (S2) placed between the output terminals of the DC/DC converter and also connected in parallel to the lamp and the capacitor in series, and an igniter. All MOSFETs (S1 in the DC/DC converter, S2 and S3) in the ballast are operated on the common voltage position (GND) of the circuit. The DC/DC converter is operated intermittently and the operation of S2 synchronizes with the operation of it to supply the lamp with an alternate square wave voltage. Operating an automotive HID lamp succeeded using the novel ballast and by setting some issues below. 1) The occurrence of the power loss when S2 is turned on. 2) The occurrence of extinction of gas discharge. This paper describes how the loss can be decreased if a part of the energy stored in the output capacitor of the DC/DC conveter is used to operate the lamp before S2 is turned on. It also describes how an inductor and a capacitor were added to the proposed electronic ballast to raise the lamp voltage in order to prevent the current from disappearing.

Today's changing demographics require that multicultural factors be considered in the delivery of quality patient-centred health care in chiropractic. Yet minimal training in cultural competency in chiropractic education leaves graduates ill-equipped to treat a diverse population. This commentary examines cultural competency training in current literature, demonstrates frameworks for curriculum integration, and suggests how cultural competency might be included in a chiropractic college curriculum. A database search yielded little evidence that cultural competency is integrated into curricula of chiropractic schools. Some journal articles note that promoting multicultural education and cultural sensitivity is an important goal. However, they provide no mechanisms as to how this can be achieved within training programs. Thus, although an undeniable need exists for all healthcare practitioners to develop cultural competency in the face of an increasingly diverse population, cultural competency education has not kept pace. Chiropractic schools must review their curricula to develop the cultural competencies of their graduates and a basic framework is suggested.

Full Text Available Erkki Huovinen’s “Varieties of Musicological Empiricism” provides a valuable analysis of some of the theoretical predicaments raised by pursuing an empirical musicology. But in this commentary, I argue for a less programmatic, and more pragmatic, approach to the term than he does. Empirical approaches in musicology have been around in one form or another for a long time, and the purpose of the label is less to identify a new ‘brand’ of musicology than to bring together a diversity of approaches that in different ways capitalise on the opportunities that data collection (in the broadest sense of the term may provide. If programme is set aside in favour of pragmatism, and a looser relationship between theory and observation accepted, then empirical musicology can be a productive way to rub ideas up against a stimulatingly resistant world.

Flatland, Edwin Abbott Abbott's story of a two-dimensional universe, as told by one of its inhabitants who is introduced to the mysteries of three-dimensional space, has enjoyed an enduring popularity from the time of its publication in 1884. This fully annotated edition enables the modern-day reader to understand and appreciate the many "dimensions" of this classic satire. Mathematical notes and illustrations enhance the usefulness of Flatland as an elementary introduction to higher-dimensional geometry. Historical notes show connections to late-Victorian England and to classical Greece. Citations from Abbott's other writings as well as the works of Plato and Aristotle serve to interpret the text. Commentary on language and literary style includes numerous definitions of obscure words. An appendix gives a comprehensive account of the life and work of Flatland's remarkable author.

United States Automotive Materials Partnership
The United States Automotive Materials Partnership LLC (USAMP) was formed in 1993 as a partnership between Chrysler Corporation, Ford Motor Company, and General Motors Corporation. Since then the U.S. Department of Energy (DOE) has supported its activities with funding and technical support. The mission of the USAMP is to conduct vehicle-oriented research and development in materials and materials processing to improve the competitiveness of the U.S. Auto Industry. Its specific goals are: (1) To conduct joint research to further the development of lightweight materials for improved automotive fuel economy; and (2) To work with the Federal government to explore opportunities for cooperative programs with the national laboratories, Federal agencies such as the DOE and universities. As a major component of the DOE's Office of FreedomCAR and Vehicle Technologies Program (FCVT) collaboration with the USAMP, the Automotive Lightweighting Materials (ALM) program focuses on the development and validation of advanced materials and manufacturing technologies to significantly reduce automotive vehicle body and chassis weight without compromising other attributes such as safety, performance, recyclability, and cost. The FCVT was announced in FY 2002 and implemented in FY 2003, as a successor of the Partnership for a New Generation of Vehicles (PNGV), largely addressed under the first Cooperative Agreement. This second USAMP Cooperative Agreement with the DOE has expanded a unique and valuable framework for collaboratively directing industry and government research efforts toward the development of technologies capable of solving important societal problems related to automobile transportation. USAMP efforts are conducted by the domestic automobile manufacturers, in collaboration with materials and manufacturing suppliers, national laboratories, universities, and other technology or trade organizations. These interactions provide a direct route for implementing newly

Full Text Available Two major drivers for the use of newer steels in the automotive industry are fuel efficiency and increased safety performance. Fuel efficiency is mainly a function of weight of steel parts, which in turn, is controlled by gauge and design. Safety is determined by the energy absorbing capacity of the steel used to make the part. All of these factors are incentives for the U.S. automakers to use both Highly Formable and Advanced High Strength Steels (AHSS to replace the conventional steels used to manufacture automotive parts in the past. AHSS is a general term used to describe various families of steels. The most common AHSS is the dual-phase steel that consists of a ferrite-martensite microstructure. These steels are characterized by high strength, good ductility, low tensile to yield strength ratio and high bake hardenability. Another class of AHSS is the complex-phase or multi-phase steel which has a complex microstructure consisting of various phase constituents and a high yield to tensile strength ratio. Transformation Induced Plasticity (TRIP steels is another class of AHSS steels finding interest among the U.S. automakers. These steels consist of a ferrite-bainite microstructure with significant amount of retained austenite phase and show the highest combination of strength and elongation, so far, among the AHSS in use. High level of energy absorbing capacity combined with a sustained level of high n value up to the limit of uniform elongation as well as high bake hardenability make these steels particularly attractive for safety critical parts and parts needing complex forming. A relatively new class of AHSS is the Quenching and Partitioning (Q&P steels. These steels seem to offer higher ductility than the dual-phase steels of similar strengths or similar ductility as the TRIP steels at higher strengths. Finally, martensitic steels with very high strengths are also in use for certain parts. The most recent initiative in the area of AHSS

High power LEDs were introduced in automotive headlights in 2006-2007, for example as full LED headlights in the Audi R8 or low beam in Lexus. Since then, LED headlighting has become established in premium and volume automotive segments and beginning to enable new compact form factors such as distributed low beam and new functions such as adaptive driving beam. New generations of highly versatile high power LEDs are emerging to meet these application needs. In this paper, we will detail ongoing advances in LED technology that enable revolutionary styling, performance and adaptive control in automotive headlights. As the standards which govern the necessary lumens on the road are well established, increasing luminance enables not only more design freedom but also headlight cost reduction with space and weight saving through more compact optics. Adaptive headlighting is based on LED pixelation and requires high contrast, high luminance, smaller LEDs with high-packing density for pixelated Matrix Lighting sources. Matrix applications require an extremely tight tolerance on not only the X, Y placement accuracy, but also on the Z height of the LEDs given the precision optics used to image the LEDs onto the road. A new generation of chip scale packaged (CSP) LEDs based on Wafer Level Packaging (WLP) have been developed to meet these needs, offering a form factor less than 20% increase over the LED emitter surface footprint. These miniature LEDs are surface mount devices compatible with automated tools for L2 board direct attach (without the need for an interposer or L1 substrate), meeting the high position accuracy as well as the optical and thermal performance. To illustrate the versatility of the CSP LEDs, we will show the results of, firstly, a reflector-based distributed low beam using multiple individual cavities each with only 20mm height and secondly 3x4 to 3x28 Matrix arrays for adaptive full beam. Also a few key trends in rear lighting and impact on LED light

This paper presents a smart cover glass based on electrowetting-on-dielectric (EWOD) actuation for automotive applications. It can remove water droplets in a wide range of sizes to allow the camera's lens to get clean at any time. The proposed cover glass offers a simple design structure to be easily installed on any device but provides a fast and energy efficient droplet cleaning operation. As proof of concept, a real imaging test is carried out using a mobile smartphone camera and landscape photography. When water droplets with different volumes are on the camera cover glass, the image of landscape photography is distorted with blurred spots. However, the distorted image is restored by removing the droplets through EWOD actuation.

Infrared absorption spectroscopy (IR) and acousto-optic tunable filter (AOTF) technology were combined to develop a portable spectrophotometer for use in engine oil analysis to identify and quantify oil contaminants and residue products, Preliminary measurements were taken with a field-portable AOTF-based spectrometer (2 to 4.5 micrometers ) and an FTIR spectrometer (2 to 25 micrometers ) for comparison. Absorption spectra of used and unused oil samples were measured and compared to determine absorption changes between the various samples resulting from oil degradation and any chemical reactions that might have taken place during high- temperature engine lubrication. These preliminary results indicate that IR spectroscopy can be used for oil quality monitoring in automotive engines, which will help predict and prevent engine failure and degradation. This work can be extended to other remote sensing applications, such as the monitoring of environmental oil spills.

The paper presents the Active Gated Imaging System (AGIS), in relation to the automotive field. AGIS is based on a fast gated-camera equipped with a unique Gated-CMOS sensor, and a pulsed Illuminator, synchronized in the time domain to record images of a certain range of interest which are then processed by computer vision real-time algorithms. In recent years we have learned the system parameters which are most beneficial to night-time driving in terms of; field of view, illumination profile, resolution and processing power. AGIS provides also day-time imaging with additional capabilities, which enhances computer vision safety applications. AGIS provides an excellent candidate for camera-based Advanced Driver Assistance Systems (ADAS) and the path for autonomous driving, in the future, based on its outstanding low/high light-level, harsh weather conditions capabilities and 3D potential growth capabilities.

The automotive dual mode hydrogen generation system is advocated as a supplementary hydrogen fuel means along with the current metallic hydride hydrogen storage method for vehicles. This system consists of utilizing conventional electrolysis cells with the low voltage dc electrical power supplied by two electrical generating sources within the vehicle. Since the automobile engine exhaust manifold(s) are presently an untapped useful source of thermal energy, they can be employed as the heat source for a simple heat engine/generator arrangement. The second, and minor electrical generating means consists of multiple, miniature air disk generators which are mounted directly under the vehicle's hood and at other convenient locations within the engine compartment. The air disk generators are revolved at a speed which is proportionate to the vehicles forward speed and do not impose a drag on the vehicles motion.

A 67 kW (90 hp) Stirling engine design, sized for use in a 1984 1440 kg (3170 lb) automobile was the focal point for developing automotive Stirling engine technology. Since recent trends are towards lighter vehicles, an assessment was made of the applicability of the Stirling technology being developed for smaller, lower power engines. Using both the Philips scaling laws and a Lewis Research Center (Lewis) Stirling engine performance code, dimensional and performance characteristics were determined for a 26 kW (35 hp) and a 37 kW (50 hp) engine for use in a nominal 907 kg (2000 lb) vehicle. Key engine elements were sized and stressed and mechanical layouts were made to ensure mechanical fit and integrity of the engines. Fuel economy estimates indicated that the Stirling engine would maintain a 30 to 45 percent fuel economy advantage comparable spark ignition and diesel powered vehicles in the 1984 period.

In Brazil, the policy for disposing industrial sludge is changing from an emphasis on using controlled landfills to other treatment or co-processing methods; however, the monitoring of organic pollutants is not mandatory. The present study evaluated two general screening methods for organic pollutants in sludge generated in an automotive industrial complex in southern Brazil. The screening was performed using Soxhlet and sonication extractions and Gas Chromatograph coupled with Quadrupole Mass Spectrometry (GC/qMS). It was concluded that both techniques were effective and that most of the compounds identified were alkanes, phenols and esters. Important pollutants were detected in the sludge, which confirms the necessity of monitoring this type of residue.

Engineers are more and more faced to the hard problem of sophisticated real-time System whereas time to market becomes always smaller. Object oriented modeling supported by UML standard brings effective solutions to such problems. However the possibility to specify real-time aspects of an application are not yet fully satisfactory Indeed, existing industrial proposals supply good answers to concurrency specification problem but they are yet limited regarding to real-time quantitative properties specification of an application. This work aims to construct a complete and consistent UML methodology based on a profile dedicated to automotive embedded Systems modeling and prototyping. This profile contains ail needed extensions to express easily the real-time quantitative properties of an application. Moreover, thanks to the formalization of UML protocol state machines, real-time concepts have been well-integrated in the object oriented paradigm. The main result of this deep integration is that a user is now able to model real-time Systems through the classical object oriented view i.e. without needing any specific knowing in real-time area. In order to answer to an industrial requirement, Systems prototyping (key point for car industry) the ACCORD/UML approach allows also to build executable models of an application. For that purpose, the method supplies a set of rules allow.ng to remove UML ambiguous semantics points, to complete semantics variation points and then to obtain a complete and coherent global model of an application being executable. The work of UML extension and its using formalization realized all along this thesis supplied also a complete and non-ambiguous modeling framework for automotive electronics Systems development. This is also a base particularly well-suited to tackle other facets of the Systems development as automatic and optimized code generation, validation, simulation or tests. (author) [fr

Full Text Available The main purpose of this paper is to provide an in-depth analysis of the anatomy of China's automotive exports, relying on the literature on firm and product heterogeneity. For this purpose, we use highly disaggregated HS 8-digit product-category level data collected by the Chinese Customs Office for 2000 and 2008, and we distinguish between foreign firms, domestic public firms, and domestic private firms. We also decompose automotive products into autos and auto parts and components (P/C. We then calculate both the extensive margins – number of products exported – and intensive margins – average value of exports per product – of China's automotive exports. We estimate gravity equations to assess the determinants of China's exports of autos and auto P/C. Overall, our analysis yields a number of new, interesting stylized facts about China's automotive exports by confirming the need for taking into account different types of heterogeneity in analyzing international trade.

Today's automotive technology curriculum is changing; curriculum revisions are being made in response to both the changing automobile and to the latest social trends and laws affecting students and teachers alike. (Author)
The increasing trend towards electric cars leads to several challenges for the automobile industry, research institutes and politics as well as for the society. Research and serial development move closer together to meet automotive standards with new components such as traction batteries integrated into hybrid and electrical drivetrains. Furthermore, the influence of e-mobility on the daily mobility behavior, the effects on the automotive supply chain and the impact on industrial production have to be taken into account. According to these complex aspects it is crucial to not only acquire specific knowledge in the particular fields but also to consider their functional interaction. Therefore, it seems essential to merge competence from science, economy and politics. This year, the annual „Conference on Future Automotive Technology“ as the follow-up of the „2. Automobiltechnisches Kolloquium München” focuses on the economical realization of widespread automotive electro mobility. Contents - Energy St...

Full Text Available The business world is changing at an impressive speed: the global financial crisis, challenging markets, technology and talent crisis have a major impact on business. The last century can be associated with the triumph of the automobile industry. At the beginning of the 21st century the automotive industry has experienced one of the largest shifts in the automotive history. The new CO2 regulations on global level have determined the automotove industry to adopt new and original technologies faster than anticipated. The emerging tendency of car sharing in larger cities added to the media information related to the negative environmental effects of car mobility generate concerns that customers were seeking a replacement to the traditional, individual car ownership. The automotive industry will face challenging years ahead taking into consideration the shifting paradigm in auto-mobility. In this context, this article aims to provide a general perspective of the tendencies in the automotive sector.

Three articles in this issue, by Bloodgood and colleagues, Hauer and colleagues, and White and colleagues, address important issues in student assessment. They use different approaches to data collection and focus on issues as broad as pass-fail grading in the preclinical years to standardized patient testing and remediation in the clinical years. However, they all remind us that assessment should not be seen as an end in itself, and they underscore the many functions that assessment can play in medical education. Drawing from these three, the authors of this commentary suggest that assessment should be designed to provide useful information for both faculty and students, at the same time minimizing stress and competition and maximizing cooperative learning. The authors assert that assessment data need to be used and that consequences should be attached to performance. In the case of poor performance, the information gained should not be used punitively. Instead, it can be used for support and remediation, giving students tools for self-improvement, assisting them to be self-reflective and gain insight into their strengths and weaknesses, and making them aware of available resources when necessary.
Full Text Available Â Abstract Tabari Commentary Translation, which is provided at the time of Samanids, is the oldest Persian translation of Koran and Persian prose books. Reviewing the prose features of this book, which is similar to standard prose of that days and has had no poetic and narrative mode, could well represent the language prose of the early period of Dari Persian. This article considered the six features of transitive and Causative verbs, verb prefix, passive verb and its forms, pray verb, intransitive verb and the use of old and applied verbs in this prose. The translators tendency to use of certain transitive verb, different form of passive verbs, two rare prefix ââ Faââ and ââvarââ, various form of pray verbs and intransitive verbs given the position and apply of objective pronoun are the unique and special features of this ancient translation of Koran.

Volkswagen (VW) is internationally recognized for quantity and quality of world-wide vehicle production and the Oak Ridge National Laboratory (ORNL) is internationally recognized in materials research and development. With automotive production ramping up in the recently constructed VW Group of America facility in Chattanooga, Tennessee, ORNL and VW initiated discussions in 2012 concerning opportunities for collaboration around ORNL’s carbon fiber and composites programs. ORNL is conducting an internationally recognized program to develop and implement lower cost carbon fibers and composites for automotive and other “energy missions” for the US Department of Energy. Significant effort is ongoing in selecting, developing, and evaluating alternative precursors, developing and demonstrating advanced conversion techniques, and developing and tailoring surface treatment, sizings, and formatting fiber for specific composite matrices and end-use applications. ORNL already had North America’s most comprehensive suite of tools for carbon fiber research and development and established a semiproduction demonstration line referred to as the Carbon Fiber Technology Facility (CFTF) to facilitate implementation of low cost carbon fiber (LCCF) approaches in early 2013. ORNL and VW agreed to collaborate in a formal Cooperative Research and Development Agreement (NFE-12-03992) specifically focused on evaluating applicability of low cost carbon fiber products for potential vehicle components. The goal of the work outlined in this report was to develop and qualify uses for carbon fiber-reinforced structures in connection with civilian ground transportation. Significant progress was achieved in evaluating and understanding lignin-based precursor materials; however, availability of carbon fiber converted from lignin precursor combined with logistical issues associated with the Visa limitations for the VW participant resulted in significantly shortening of the collaboration

Research on racial residential segregation and health typically uses multilevel, population-based, slice-in-time data. Although research using this approach, including that by Kershaw et al. (Am J Epidemiol. 2013;177(4):299-309), has been valuable, I argue that to advance our understanding of how residential segregation influences health and health disparities, it is critical to incorporate a life-course perspective and integrate social theory. Applying a life-course perspective would entail modeling transitions, cumulative risk, and developmental and dynamic processes and mechanisms, as well as recognizing the contingency of contextual effects on different social groups. I discuss the need for analytic methods appropriate for modeling health effects of distal causes experienced across the life course, such as segregation, that operate through multiple levels and sequences of mediators, potentially across decades. Sociological theories of neighborhood attainment (e.g., segmented assimilation, ethnic resurgence, and place stratification theories) can guide effect-modification tests to help illuminate health effects resulting from intersections of residential processes, race/ethnicity, immigration, and other social determinants of health. For example, nativity and immigration history may crucially shape residential processes and exposures, but these have received limited attention in prior segregation-health literature.
Social epidemiologists are interested in determining the causal relationship between income and health. Natural experiments in which individuals or groups receive income randomly or quasi-randomly from financial credits (e.g., tax credits or cash transfers) are increasingly being analyzed using instrumental variable analysis. For example, in this issue of the Journal, Hamad and Rehkopf (Am J Epidemiol. 2016;183(9):775-784) used an in-work tax credit called the Earned Income Tax Credit as an instrument to estimate the association between income and child development. However, under certain conditions, the use of financial credits as instruments could violate 2 key instrumental variable analytic assumptions. First, some financial credits may directly influence health, for example, through increasing a psychological sense of welfare security. Second, financial credits and health may have several unmeasured common causes, such as politics, other social policies, and the motivation to maximize the credit. If epidemiologists pursue such instrumental variable analyses, using the amount of an unconditional, universal credit that an individual or group has received as the instrument may produce the most conceptually convincing and generalizable evidence. However, other natural income experiments (e.g., lottery winnings) and other methods that allow better adjustment for confounding might be more promising approaches for estimating the causal relationship between income and health. © The Author 2016.

Full Text Available The state of catalysts plays a key role in automotive exhaust gas aftertreatment. The soot or ash loading of Diesel particulate filters, the oxygen loading degree in three-way catalysts, the amount of stored ammonia in SCR catalysts, or the NOx loading degree in NOx storage catalysts are important parameters that are today determined indirectly and in a model-based manner with gas sensors installed upstream and/or downstream of the catalysts. This contribution gives an overview on a novel approach to determine the catalyst state directly by a microwave-based technique. The method exploits the fact that the catalyst housing acts as a microwave cavity resonator. As “sensing” elements, one or two simple antennas are mounted inside the catalyst canning. The electrical properties of the catalyst device (ceramic honeycomb plus coating and storage material can be measured. Preferably, the resonance characteristics, e.g., the resonance frequencies, of selected cavity modes are observed. The information on the catalyst interior obtained in such a contactless manner is very well correlated with the catalyst state as will be demonstrated for different exhaust gas aftertreatment systems.
The objectives of this analytical study were: to select one advanced automotive diesel engine (AAD) concept which would increase the tank mileage of a 3,000 pound passenger car from the present 35 mpg to at least 52 mpg; to identify long term component research and development work required to bring the selected concept to fruition; and to prepare a development strategy that will bring the selected concept to a prototype testing phase.

Installation dimensions are 621 mm length x 589 mm width x 479 mm height (24.4 inch x 22 inch x 18.9 inch).
An exciting era is evolving in the application of new materials technologies to automotive applications. The desire on the part of the automobile industry to completely satisfy the customers while concurrently meeting increasing demands and regulations for stringent emission control and fuel efficiency is opening a plethora of opportunities for new materials. In many cases, materials solutions are the only mechanisms for resolving some of the upcoming issues. The materials scientist and engineer will therefore have a primary role to play and will assume a position of significance hithertofore unseen in the automobile industry. The nature of the industry dictates that changes are primarily evolutionary with respect to chronology but nevertheless some of the future material changes will be revolutionary in nature. This presentation will treat three primary systems of the vehicle separately, based on the different materials approaches which will be adopted. These areas are: (1) skin panels, (2) structures, and (3) powertrains. The competition between a variety of new materials in these 3 systems will be discussed in detail with the various tradeoffs being outlined. Amongst the more prominent of the new breed of materials will be new steel technologies, structural plastics (FRP), aluminum alloys (conventional and rapidly solidified), titanium alloys, metal matrix composites and smart materials (electrorheological fluids, etc.). The pace of development and application is accelerating rapidly and the impetus is likely to increase.
Full Text Available This paper employs the concept of Effective Protection in order to calculate the real level of protection that has favored the automotive assembly industry in Colombia and to value if this level of protection has helped to achieve the goals of an Import Substitution Policy. A policy that seeks to establish, through this protection mechanism a national industry of consumer durable goods, with an increasing share of domestic inputs generating alongside new dynamics in investment and employment generation. For this purpose, this paper works with data from the Colombian National Manufacture Survey (Encuesta Nacional Manufacturera de Colombia, data provided by the industry on incorporation of local inputs, and a review of changes in policy and legislation affecting the way in which this mechanism operates. Contrary to what would be expected, analysis shows that share of local inputs has decreased, bringing as a result that the cost of protection has been very high when compared to investment and employment generation. The paper concludes with some thoughts as to the convenience of maintaining this type of policy.

In recent years, environmental issues, such as climate change and global warming due to the excessive development of industry, have attracted increasing attention of citizens worldwide. It is known that CO2 accounts for the largest proportion of greenhouse gases. Therefore, how to reduce CO2 emissions during the life cycle of a product to lessen its impact on environment is an important topic in the industrial society. Furthermore, it is also of great significance to cut down the required energy so as to lower its production costs during the manufacturing process nowadays. This study presents the carbon footprint of an automotive ignition coil and its partial materials are defined to explore their carbon emissions and environmental impact. The model IPCC GWP100a calculates potential global greenhouse effect by converting them into CO2 equivalents. In this way, the overall carbon footprint of an ignition coil can be explored. By using IPCC GWP100a, the results display that the shell has the most carbon emissions. The results can help the industry reduce the carbon emissions of an ignition coil product.
Full Text Available The advantages of Usage-Based Insurance for automotive covers over conventional rating methods have been discussed in literature for over four decades. Notwithstanding their adoption in insurance markets has been slow. This paper seeks to establish the viability of introducing fleet Telematics-Based Insurance by investigating the perceptions of insurance operators, tracking service providers and corporate fleet owners. At its core, the study involves a SWOT-analysis to appraise Telematics-Based Insurance against conventional premium rating systems. Twenty five key stakeholders in Malta, a country with an insurance industry that represents others in microcosm, were interviewed to develop our analysis. We assert that local insurers have interests in such insurance schemes as enhanced fleet management and monitoring translate into an improved insurance risk. The findings presented here have implications for all stakeholders as we argue that telematics enhance fleet management, TBI improves risk management for insurers and adoption of this technology is dependent on telematics providers increasing the perceived control by insurers over managing this technology.

The role of perioperative nurses is unique in that they must be able to maintain clinical expertise in nursing practice and develop technical surgical skills. Even experienced perioperative nurses who transfer to the OR from other hospital settings or change employment to another facility require a certain amount of preceptor orientation. The current shortage of experienced perioperative nurses calls for the development of strategies to increase their number. "Inviting" OR preceptorship experiences may increase the recruitment, retention, and, subsequently, number of perioperative nurses. Nurse preceptors may be either personally or professionally "inviting" or "disinviting" when sharing knowledge and techniques with less experienced nurses. This article includes findings from a research study of perioperative nurse preceptees. The intent of the study was to identify whether the invitational operating room teaching survey could be used as a reliable tool in the OR. Survey items evaluate preceptees' attitudes toward preceptors and characteristics of effective preceptors. Cronbach's alpha reliability analysis revealed reliability of the tool.

Lerum and Dworkin offer a provocative interdisciplinary feminist commentary on the Report of the APA (American Psychological Association) Task Force on the Sexualization of Girls. This commentary notes limitations to their argument and evidence, which make it a less convincing critique of the report's conclusions. Most notably, Lerum and Dworkin omit a developmental approach to the topic of sexualization and media exposure. In addition, their criticism that the report over-determines the negative effects (i.e., overstates the negative effects and ignores the positive effects) of sexualization on girls is unsupported by the empirical literature. This commentary also addresses their concerns about the language used in the report and highlights the need for clear and precise language in this dialogue.

An Automotive Electronic Control Units (ECU) development project embedded within a car Environment is constantly under attack of a continuous flow of modifications of specifications throughout the life cycle. Root causes for those modifications are for instance simply software or hardware implementation errors or requirement changes to satisfy the forthcoming demands of the market to ensure the later commercial success. It is unavoidable that from the very beginning until the end of the project “requirement changes” will “expose” the agreed objectives defined by contract specifications, which are product features, budget, schedule and quality. The key discussions will focus upon an automotive radio-navigation (infotainment) unit, which challenges aftermarket devises such as smart phones. This competition stresses especially current used automotive development processes, which are fit into a 4 Year car development (introduction) cycle against a one-year update cycle of a smart phone. The research will focus the investigation of possible impacts of changes during all phases of the project: the Concept-Validation, Development and Debugging-Phase. Building a thorough understanding of prospective threats is of paramount importance in order to establish the adequate project management process to handle requirement changes. Personal automotive development experiences and Literature review of change- and configuration management software development methodologies led the authors to new conceptual models, which integrates into the structure of traditional development models used in automotive projects, more concretely of radio-navigation projects.

This response to Katz's commentary is based on our team's experiences and findings in bystander intervention design and evaluation among male and female adolescents in several high school settings. Three themes emerged in reflecting on "what worked" in our large evaluation in light of Katz's commentary. First, our field needs data from multiple rigorous bystander intervention evaluations. Second, bystander interventions must be acceptable to the population receiving the intervention. Third, engaging all adolescent and young adults in prevention independent of sex or sexual orientation is essential to reduce sexual violence including harassment and bullying.
In this article, the author responds to three commentaries about his article "Bystander Training as Leadership Training: Notes on the Origins, Philosophy, and Pedagogy of the Mentors in Violence Prevention Model," published in this volume. Topics covered in the commentaries and response include questions about evaluation and evidence for program effectiveness; the necessity for gender violence prevention education to be gender transformative and part of a comprehensive, multilevel prevention approach, especially for adolescents; and the degree to which Mentors in Violence Prevention (MVP), as a "social justice"-oriented program, incorporates intersectional and anti-oppression frameworks and perspectives.

The automotive industries of Southeast Asia have grown significantly but unevenly. Thailand has outperformed its neighbours in Malaysia, Indonesia and the Philippines with regard to production and, most notably, export volumes. But the Thai auto industry has not exhibited the level of local...... (indigenous) technology capacity and input growth seen in South Korea, Taiwan and, increasingly, in China. The 1997–98 and 2008 financial and economic crises generally reinforced pre-existing national automotive strategies, but to different degrees: They strongly accelerated an earlier Thai move to exports...... whose very success weakened pressures for upgrading; encouraged more moderate automotive liberalisation in Indonesia and, to a lesser extent, in the Philippines; but promoted only minimal changes to Malaysia’s relatively protectionist national car strategy.

In this paper, we describe a novel software tool named OASIS (AutOmotive Analysis and Safety EngIneering InStrument). OASIS supports automotive safety engineering with features allowing the creation of consistent and complete work products and to simplify and automate workflow steps from early analysis through system development to software development. More precisely, it provides support for (a) model creation and reuse, (b) analysis and documentation and (c) configuration and code generation. We present OASIS as a part of a tool chain supporting the application of a safety engineering workflow aligned with the automotive safety standard ISO 26262. In particular, we focus on OASIS' (1) support for property checking and model correction as well as its (2) support for fault tree generation and FMEA (Failure Modes and Effects Analysis) table generation. Finally, based on the case study of hybrid electric vehicle development, we demonstrate that (1) and (2) are able to strongly support FTA (Fault Tree Analysis) and FMEA

Low-density lipoprotein oxidation is implicated in the development of atherosclerosis. Plasma susceptibility to oxidation may be used as a marker of low-density lipoprotein oxidation and thus predict atherosclerotic risk. In this study the authors investigated the relationship between plasma susceptibility to oxidation and exposure to automotive pollution in a group of automobile mechanics (n = 16) exposed to high levels of automotive pollution, vs. matched controls (n = 13). The authors induced plasma oxidation by a free radical initiator and they determined susceptibility to oxidation by (1) change in absorbance at 234 nm, (2) lag time to conjugated diene formation, and (3) linear slope of the oxidation curve. Mechanics had significantly higher values (mean +/- standard error) for change in absorbance (1.60 +/- 0.05 vs. 1.36 +/- 0.05; p automotive pollutants increases plasma susceptibility to oxidation and may, in the long-term, increase the risk of developing atherosclerosis.

In many cases it has been found that advances made in one technical field can contribute to other fields. An investigation is in this connection conducted concerning subjects from contemporary NASA programs and projects which might have relevance and potential usefulness to the automotive industry. Examples regarding aerospace developments which have been utilized by the automotive industry are related to electronic design, computer systems, quality control experience, a NASA combustion scanner and television display, exhaust gas analyzers, and a device for suppressing noise propagated through ducts. Projects undertaken by NASA's center for propulsion and power research are examined with respect to their value for the automotive industry. As a result of some of these projects, a gas turbine engine and a Stirling engine might each become a possible alternative to the conventional spark ignition engine.

The usage of rubbers has always been so important, especially in automotive industries. Rubbers have a hyper elastic behaviour which is the ability to withstand very large strain without failure. The normal applications for rubbers are used for shock absorption, sound isolation and mounting. In this study, the predictions of fatigue life of an engine mount of rubber automotive components were presented. The finite element analysis was performed to predict the critical part and the strain output were incorporated into fatigue model for prediction. The predicted result shows agreement in term of failure location of rubber mount.

Full Text Available This paper lays out the main features of the global automotive industry and identifies several important trends. Logistics operations (inbound and outbound in the automotive supply chain are complex and account for large expenses and therefore are segments in the value chainwhere improvements can be made. Better coordination between inbound and outbound logistics contributes to optimising the supply chains, to reducing inventories and to responding to consumer requests. As economies grow, the competition shifts towards brand image and customisation and here the speed and reliability of logistics operations becomes a critical elements.
Estimator development for synchronous rectification of the automotive alternator is a desirable approach for estimating alternator's back electromotive forces (EMFs) without a direct mechanical sensor of the rotor position. Recent theoretical studies show that estimation of the back EMF may be observed based on system's phase current model by sensing electrical variables (AC phase currents and DC bus voltage) of the synchronous rectifier. Observer design of the back EMF estimation has been developed for constant engine speed. In this work, we are interested in nonlinear observer design of the back EMF estimation for the real case of variable engine speed. Initial back EMF estimate can be obtained from a first-order sliding mode observer (SMO) based on the phase current model. A fourth-order nonlinear asymptotic observer (NAO), complemented by the dynamics of the back EMF with time-varying frequency and amplitude, is then incorporated into the observer design for chattering reduction. Since the cost of required phase current sensors may be prohibitive, the most applicable approach in real implementation by measuring DC current of the synchronous rectifier is carried out in the dissertation. It is shown that the DC link current consists of sequential "windows" with partial information of the phase currents, hence, the cascaded NAO is responsible not only for the purpose of chattering reduction but also for necessarily accomplishing the process of estimation. Stability analyses of the proposed estimators are considered for most linear and time-varying cases. The stability of the NAO without speed information is substantiated by both numerical and experimental results. Prospective estimation algorithms for the case of battery current measurements are investigated. Theoretical study indicates that the convergence of the proposed LAO may be provided by high gain inputs. Since the order of the LAO/NAO for the battery current case is one order higher than that of the link

Automotive human-machine interface (HMI) design is facing new challenges due to the technological advances of the last decades. The design process has to be adapted in order to address human factors and road safety challenges. It is now widely accepted that user involvement in the HMI design process is valuable. However, the current form of user involvement in industry remains at the stages of concept assessment and usability tests. Moreover, the literature in other fields (e.g. information systems) promotes a broader user involvement with participatory design (i.e. the user is fully involved in the development process). This article reviews the established benefits of participatory design and reveals perspectives for automotive HMI quality improvement in a cognitive ergonomic framework. Practitioner Summary: Automotive HMI quality determines, in part, drivers' ability to perform primary driving tasks while using in-vehicle devices. User involvement in the design process is a key point to contribute to HMI quality. This article reports the potential benefits of a broad involvement from drivers to meet automotive HMI design challenges.

One method of assessing the sustainability of manufactured products involves performing a life cycle analysis for a product and comparing it to alternative ones, or else examining if individual stages of the product can be modified. LCA applications are being used more extensively, especially in the automotive and related industries. Automotive plastics in particular are being scrutinized with much greater care. Plastic components have replaced metal ones in vehicle manufacturing to improve vehicle fuel efficiency and aesthetics. However, at the end of a vehicle's life, recycling rates for plastic are negligible when compared to those of steel. In order to gain the full environmental benefits of using plastic as a vehicle material, plastics must be recycled at the end of a vehicle's life, especially given their increasing use. While a variety of processes have been developed for the recycling of automotive plastics, the challenges of sorting, processing, and finally recycling a heterogeneous mixture of used plastics have yet to be effectively solved. A preliminary life cycle assessment of a plastic automotive fascia demonstrates the usefulness of this eco-balance technique in evaluating potential improvements to manufacturing and end-of-life processes. Improving the manufacturing process may reduce environmental burdens to a larger extent than just recycling the plastic. (author)

This commentary is intended to supplement the accompanying review of sleep problems in childhood psychiatric disorders by Gregory and Sadeh. A number of considerations are outlined because of their relevance to both clinical practice and research concerning assessment and treatment of sleep disturbance in children in general and especially those with psychiatric and/or neurological conditions. These considerations (which illustrate the importance of combined medical and psychological involvement) are as follows: the importance of screening for sleep disturbance which otherwise may well be overlooked; the need to specify sleep disorders rather than simply nonspecific sleep problems as this will guide choice of appropriate advice and treatment; the risk of sleep disorders being misdiagnosed because of clinicians' unfamiliarity with the sleep disorders field; the possibility that a child's sleep disturbance is of multiple aetiology; a wide range of treatments for disturbed sleep is now described from which a choice is possible given an accurate diagnosis; sleep problems may be intensified if a child's condition is complicated by intellectual disability but the same principles of assessment and management apply as in other children in the expectation that treatment can be effective. © 2016 Association for Child and Adolescent Mental Health.

Volumes 1 to 3 of the IEA/AFIS Automotive Fuels Survey, address the most well-known automotive fuels and fuel production routes. Less well-known fuels and energy sources that are not used in combustion engines, e.g. electricity, were excluded from these volumes. In this report fuel routes and fuels that have not been addressed in the first volumes will be analysed. In this report, each chapter starts with a short description of the fuel(route) and its status of development (e.g. if the idea has been abandoned or if the fuel is already sold at a fuel station). Then the different aspects of that fuel are described as far as the information is available. This is limited to information that can not be found in volumes one and two of the Automotive Fuels Survey. For example: for the diesel-water mixtures, the production of diesel is not be described. If comparisons are made, they are made either relative to an already described fuel(route) that is related (e.g. biogas will be compared with natural gas) or relative to diesel and gasoline as was done in volume 1 and 2 of the Automotive Fuels Survey. For some of the fuels, the relation with a fuel already covered in volume one and two is very strong. For these fuels more information can be found in the chapters on the related fuel in the other volumes of the Automotive Fuels Survey. The following fuels are covered in this report: biodiesel from used oil and fat, biodiesel and biogasoline from algae, diesel from hydrothermal upgrading, biogas, hythane, Fischer-Tropsch diesel, diesel-water blends, higher ethers, and electricity. 74 refs.

This commentary promotes discussion on the imaginary provided by Sanaz Farhangi in her article entitled, Contribution to activity: a lens for understanding students' potential and agency in physics education. The commentary is concerned with aligning ontological assumptions in research accounts of learning and development with transformative aims. A broad definition of ontology as the theory of existence is preferred. Sociocultural approaches share relational ontology as a common foundation. I agree with scholars elaborating Vygotsky's Transformative Activist Stance that a relational ontology does not imply activism. However, I argue that relational ontology provides a necessary and sufficient theoretical grounding for intentional transformation. I draw upon positioning theory to elaborate the moral aspects of language use and to illustrate that a theory of being as relational already eliminates the transcendental position. I draw on Farhangi's article to further the discussion on the necessity and sufficiency of relational ontology and associated grammars in accounting for activism.

The topic of regulation is commonplace in society, yet it seems to receive little explicit consideration in discussions on undergraduate medical education. The accompanying articles by Hauer and colleagues, White and colleagues, and Bloodgood and colleagues approach the topic of regulation from several different viewpoints. In this commentary, we too approach the topic of regulation from several different viewpoints: sociology, learning (self-regulated learning), and accountability. In this commentary, we present both theoretical and practical issues with the aim of initiating an open, scholarly discussion in the field of medical education. Ultimately, we hope other medical educators will seriously contemplate the questions raised and, more importantly, will consider employing these theoretical perspectives into future research efforts.

Full Text Available This commentary addresses the hypothesis that empathy is a tool for embodiment and skillful performance in the presentation of opera and art song. It discusses the need to clearly and effectively define the term "empathy," and considers research from acting and theatre that speaks directly to how embodiment occurs in vocal performance, when that performance is attached to a character specifically. It concludes with some additional acting exercises singers may find useful.
The prohibition on taking human life is one of the cornerstones of Buddhist ethics, but there is often confusion about the interpretation of this prohibition in different contexts. In his commentary on the third parajika in the Samantapasadika, Buddhaghosa sets out to clarify the legal provisions of the monastic precept against taking life. The root text and his comments on it are relevant to the contemporary debate on euthanasia, and this paper considers what light Buddhist jurisprudence can shed on this moral dilemma.

Despite the fact that thermoelectric (TE) devices are compact, quiet, rugged, stable and very reliable, thermoelectrics have found only niche applications because they are also inefficient (less that 5% conversion efficiency is typical) and costly. The key to more widespread acceptance of thermoelectric is the development of materials that are capable of higher conversion efficiency, but other fundamental materials parameters play a role not less important to open to large applications and markets. In particular the automotive sector requires low materials density, materials made from widely-available pure elements with very large supply chains, non-toxicity of elements and potential compliance with REACH and RoHS obligations and low raw material cost combined with low manufacturing costs. The impact of novel TE materials on automotive application will be described focusing on promising nano magnesium silicide and skutterudites.

The primary objective of this paper is to show where the engineering of risk management is placed and how its implementation has been tried in multinational companies in automotive industry from Romania. A large number of companies don't use a strategy to avoid the engineering risk in their design products. The main reason is not because these companies haven't heard about standards for risk management such as ISO 31000; the problem is that the business units which were summed up, have just set up a risk list at the beginning of the project, without any follow up. The purpose of this article is to create an implementation risk tracking in automotive industry companies in Romania, due to a change request from customers according to supply companies within the quality process, in the research and development phase.

Pre-treatment processes for automotive applications in Europe are optimized firstly due to the increasing use of aluminum and coated steel for car bodies and parts and secondly due to environmental issues. Prephosphated coated steel, mainly electrogalvanized steel with a trication zinc phosphate layer applied in the steel mill is used by many car manufacturers. Several R and D projects are under way to coat aluminum sheet with inorganic or organic layers to enhance forming, welding and joining properties. Environmental aspects initiated the development of cleaners with biodegradable and alkylphenolethoxylate-free surfactants, liquid grain refiners with longer bath life-time, nickel or nitrite-free zinc phosphate products and chrome-free passivations. All of these products are in use in many automotive body lines except the nickel-free phosphating process which is being tested in OEM parts lines. Details of the processes in a phosphating line are described including a section on phosphating of aluminum.
Since this year there can be no doubt that "sustainability" has become the top issue in the automotive sector. Volkswagen's CEO Prof. Dr. Martin Winterkorn attacked incumbents like BMW Group (so far the "most sustainable car manufacturer" for the 8th consecutive year) or Toyota (producer of the famous "Prius") head-on by boldly stating to become "the most profitable and most sustainable car manufacturer worldwide by 2018" . This announcement clearly shows that "sustainability" and "profitability" no longer are considered as conflicting targets. On the contrary, to Prof. Dr. Winterkorn : "climate protection is a driver for economic growth". To prime discussions, the plenary talk will give a brief overview of the entire range of energy efficiency in the automotive sector: based on the multiple drivers behind energy efficiency, practical examples are presented along the entire life-cycle of cars (R&D, production, usage and recycling). These "cases" include big automobile producers as well as their respectiv...
Full Text Available This study aims to determine the effects of the automotive industry on carbon dioxide emissions for the period from 1997 to 2010 for diverse economies, as well as the relationships between carbon dioxide discharges and output. The study applies cointegration and causality tests to validate these associations. The results of the Johansen cointegration test depict long-run associations between the quantity of passenger cars and carbon dioxide emissions in France, Sweden, Spain, Hungary and Japan. In addition, significant relations were observed between output and carbon dioxide discharges in Spain, Canada, India and Japan. Changes in output had substantial impact on emissions in Germany, Canada and India. The results also show that the number of passenger cars influences the magnitude of emissions in multiple economies. In conclusion, the automotive industry has to be considered in policies that aim to reduce carbon dioxide emissions.

Aluminum use is growing in automotive closures and body in white applications to improve vehicle performance and fuel economy. The auto industry is looking for higher-strength aluminum materials needed for strength-driven safety-critical parts. Through cooperation with industrial partners and support from the Department of Energy (DOE), multiple experimental 7xxx alloys were developed for automotive applications. The objective is to enable complex shapes to be formed at temperatures below 225°C. A demonstration part has been developed that is representative of the forming challenges within a current hot-stamped door ring component. This part tooling has been built and installed into a press line which includes blank heating and robotic transfer. Forming trials of these alloys are currently underway and the formability, strength and corrosion performance of these materials are being evaluated.
Full Text Available The economic crisis has affected many areas but the auto industry is perhaps one of the most affected. Renault, Ford, General Motors, Toyota, Volkswagen, BMW are just some of the big players caught unprepared. Through this paper we propose an analysis of the automotive market in Romania in order to understand the sales decrease of the last two years. At the same time we aimed at understanding the reasons that led to a decrease in car sales, what were the measures taken by the government to stop this phenomenon and how the economic crisis influenced the automotive field in Romania. An objective image of the situation in the automobile market in Romania at this moment also requires an analysis of the marketing environment and the changes it has undergone over time. Last but not least we will try to find a series of measures to re-launch the car market in Romania.

Debate continues regarding the effectiveness of Family Witnessed Resuscitation and little is known about the reasons why staff invite family presence. Explore why health professionals invite or not invite Family Witnessed Resuscitation. Descriptive qualitative study. Three open-ended questions enabled 114 clinicians to describe why they would or would not invite family presence. Data were analysed using qualitative data analysis. Four themes representing factors that influenced staff decision to invite or not invite Family Witnessed Resuscitation were identified: motivating factors, personal choice, staff judgment, and organisational factors. Motivating factors described reasons to invite family presence, and staff and organisational factors were reasons to not invite family presence. Family presence can be beneficial for staff and family and is likely to be motivated by family-specific factors where this choice is appropriate for all stakeholders. Participants described factors that can impact on the appropriateness of inviting family presence and these need to be considered before an invitation is extended. To support all parties throughout the process it is imperative that a skilled support person be available to the family and that written policies and guidelines be available for staff.

Chennai, also called as Detroit of India due to presence of Automotive Industry producing over 40 % of the India's vehicle and components. During 2001-2002, the Automotive Component Industries (ACI) in Ambattur, Thirumalizai and Thirumudivakkam Industrial Estate, Chennai has faced problems on infrastructure, technology, procurement, production and marketing. The objective is to study the Quantitative Performance of Chennai Automotive Industry Cluster before (2001-2002) and after the CDA (2008-2009). The methodology adopted is collection of primary data from 100 ACI using quantitative questionnaire and analyzing using Correlation Analysis (CA), Regression Analysis (RA), Friedman Test (FMT), and Kruskall Wallis Test (KWT).The CA computed for the different set of variables reveals that there is high degree of relationship between the variables studied. The RA models constructed establish the strong relationship between the dependent variable and a host of independent variables. The models proposed here reveal the approximate relationship in a closer form. KWT proves, there is no significant difference between three locations clusters with respect to: Net Profit, Production Cost, Marketing Costs, Procurement Costs and Gross Output. This supports that each location has contributed for development of automobile component cluster uniformly. The FMT proves, there is no significant difference between industrial units in respect of cost like Production, Infrastructure, Technology, Marketing and Net Profit. To conclude, the Automotive Industries have fully utilized the Physical Infrastructure and Centralised Facilities by adopting CDA and now exporting their products to North America, South America, Europe, Australia, Africa and Asia. The value chain analysis models have been implemented in all the cluster units. This Cluster Development Approach (CDA) model can be implemented in industries of under developed and developing countries for cost reduction and productivity

Values of current energy technology costs and prices, available from a variety of sources, can sometimes vary. While some of this variation can be due to differences in the specific materials or configurations assumed, it can also reflect differences in the definition and context of the terms "cost" and "price." This fact sheet illustrates and explains this latter source of variation in a case study of automotive lithium-ion batteries.

Roll forming enables the manufacturing of longitudinal components from materials that combine high strength with limited formability and is increasingly used in the automotive industry for the manufacture of structural and crash components. An extension of conventional roll forming is the Flexible Roll Forming (FRF) process where the rolls are no longer fixed in space but are free to move which enables the forming of components with variable cross section over the length of the part. Even though FRF components have high weight saving potential the technology has found only limited application in the automotive industry. A new flexible forming facility has recently been developed that enables proof of concept studies and the production of FRF prototypes before a full FRF line is built; this may lead to a wider uptake of the FRF technology in the automotive industry. In this process, the pre-cut blank is placed between two clamps and the whole set up moves back and forth; a forming roll that is mounted on a servo-controlled platform with six degrees of freedom forms the pre-cut blank to the desired shape. In this study an initial forming concept for the flexible roll forming of an automotive component with variable height is developed using COPRA® FEA RF. This is followed by performing experimental prototyping studies on the new concept forming facility. Using the optical strain measurement system Autogrid Compact, material deformation, part shape and wrinkling severity are analysed for some forming passes and compared with the numerical results. The results show that the numerical model gives a good representation of material behaviour and that with increasing forming severity wrinkling issues need to be overcome in the process.

Full Text Available Seminary students, despite having graduated from bachelors programs, struggle to make sense of the goals, processes, skills, and resources of research as graduate students. Beyond brief introductions to research, a scattered number of seminaries have developed either a separate theological information literacy course or have taken a through-the-curriculum approach to enhancing the information abilities of students. The former, however, separates information literacy from the curriculum, while the latter is difficult to implement and maintain. Living in a world of information glut, seminary professors are finding that traditional information dissemination models of education are becoming less viable. What is more, such models tend to teach students about a discipline rather than inviting them into it. These problems present a unique opportunity to place the teaching of information literacy at the foundation of theological education. With such an approach, students may be invited into the disciplines of their professors and enabled to practice these disciplines, thus becoming equipped to turn knowledge into praxis.

Nowadays, the measurement and management of color quality of the gonio-apparent materials is complex, but highly demanded in many industrial sectors, as automotive, cosmetics, plastics for consumer electronics, printing inks, architectural coatings, etc. It is necessary to control complex instrumentation and to do visual assessments of texture and color differences to get, for instance, a visual harmony in car bodies; and a profound knowledge of physics and chemistry of special-effect pigments for their optical formulation to obtain attractive visual effects in coatings, plastics, etc, combining among them and with solid pigments. From University of Alicante, for the academic year 2013-14, we are organizing the first MSc degree in Color Technology for the Automotive Sector, with a design of contents embracing CIE colorimetry and visual perception, included the AUDI2000 color difference formula, instrumentation and color management software, fundamentals of coatings and plastics in the automotive sector, and, optical formulation of pigments. The MSc syllabus, with 60 ECTS, is designed to be taught in two semesters: from September to February with on classroom theoretical and practical activities, and, from March to June at virtual level, with internships of training in some companies. Therefore, the MSc Thesis would be the performance report during the internship in companies or research institutions. Some multinational companies, both as car makers and coatings and plastics providers, from European and non-European countries have already shown their support and interest in welcoming students for specific training, even some job offers when the first MSc edition finishes.
Automobiles are still increasing in number in Japan. If this continues, CO 2 emissions in this sector may increase through the first half of the 21st century. Consequently, a study of measures for reducing these CO 2 emissions is essential. In this paper, possible automotive technologies, improvements in fuel consumption and the introduction of electric vehicles are discussed. These measures are then evaluated for the Japanese case. Furthermore, market penetration of these technologies is evaluated, using life-cycle cost analysis based on initial cost and annual fuel cost. It is concluded that reducing CO 2 emissions to 1995 levels by 2010 is possible. This would require the simultaneous implementation of fuel-consumption improvements and the introduction of electric vehicles. However, automotive consumers would be reluctant to accept these technologies, particularly electric vehicles, because of their high purchase-price and low benefits in terms of operating economy. Acceptance will require financial and institutional support from the public sector in introducing these automotive technologies into the Japanese transportation sector. (author)

In the present research work an innovative material, made of steel skin and sheet molding compound core, is presented and is aimed to be utilized for the production of automotive body frames. For a precise description of the laminate structure, the material properties of all the components, including the adhesive utilized as an interlayer, have been carried out, along with the simple tension test of the composite material. The result have shown that the proposed laminate structure has a specific yield strength 114% higher than 6061 T6 aluminum, 34% higher than 7075 T6 aluminum, 186% higher than AISI 304 stainless steel (30HRC) and 42% than SK5 high-strength steel (52HRC), showing its reliability and convenience for the realization of automotive components. After calibrating the material properties of the laminate structure, and utilizing as reference the simple tension results of the laminate structure, the derived material properties have been utilized for the simulation of the mechanical behavior of an automotive B-pillar. The results have been compared with those of a standard B-pillar made of steel, showing that the MS-SMC laminate structure manifests load and impact carry capacity comparable with those of high strength steel, while granting, at least, an 11% weight reduction.

The reduction of total vehicle weight and lowering of moving masses within the engine are key elements to overcome future emission challenges of the automotive industry. Within a German BMBF funded project the melt spinning technology will be driven to a series production status. The very fast cooling condition of the melt leads to a nano-structure of the aluminium material. This results in new material properties of known alloys. The strength increases dramatically without lowered forming behaviour. With this process the freedom of designing complex alloys is very flexible. Different alloys have been investigated for several applications, where high strength at room and elevated temperatures and/or high wear resistance is required. This paper presents some results regarding the processing, microstructure and mechanical properties of a developed Al-Ni-Fe alloy. This joined research project with partners from the automotive industry as well as automotive suppliers and universities is funded by the German BMBF 'NanoMobile' Program under Project number 03X3008.

The core of future automotive lightweight materials is the joining technology of various material mixes. The type of joining will be essential, particularly in electrified propulsion systems, especially as an improved electrical energy transmission leads to a higher total efficiency of the vehicle. The most evident parts to start the optimization process are the traction battery, the electrical performance modules and the engines. Consequently aluminum plays a very central role for lightweight construction applications. However, the physical-technical requirements of components often require the combination with other materials. Thus the joining of mixed material connections is an essential key technology for many of the current developments, for example in the areas E-Mobility, solar energy and lightweight construction. Due to these advantages mixed material joints are already established in the automotive industry and laser beam remote welding is now a focus technology for mixed material connections. The secret of the laser welding process with mixed materials lies within the different areas of the melting phase diagram depending on the mixing ratio and the cooling down rate. According to that areas with unwanted, prim, intermetallic phases arise in the fusion zone. Therefore, laser welding of mixed material connections can currently only be used with additional filler in the automotive industry.

Fuel cells are in varying stages ofcommercialization for both automotive and non-automotive applications. The fuel cell industry has made substantial progress but still needs to reduce costs and improve performance to compete successfully with established technologies. In just 5 years, costs have been reduced by a factor of two while improving efficiency and durability. Based on interviews with fuel cell manufacturers in the U.S., Japan and the EU and information from published sources, a model of non-automotive fuel cell markets is constructed and used to estimate the impacts of government policies and to project the potential evolution of the industry to 2025. The model includes the effects of learning-by-doing, scale economies and exogenous technological progress on component and system costs, estimates customer choices between fuel cell and competing established technologies, and attempts to measure the impacts of government policies. With continued policy support it appears likely that the industry can become self-sustaining within the next decade.
Full Text Available This article clarifies the impact of national culture in the after sales service in the automotive sector. Introduction and objectives: After-sales services have become paramount in the automobile industry. However, they are not sufficiently researched, particularly in emerging markets. Here an academic gap exists because, within the automotive research literature, culture is a widely neglected issue. Thus no explicit knowledge can be applied regarding emerging markets service demand behaviour, which might be a crucial point, as some of these countries culture is different to the western culture. Methods: The research is based in a survey carried out among Chinese premium brand automotive customers. Results: It shows which individual level values are causal and positively contribute to the perception of service quality and loyalty behaviour by customers. Conclusion: The article providing a guideline how the entire process chain of after-sales services could be researched and applies successfully the individual level value theory by Schwartz. Implications and research limitation: Brand loyalty is well explained by perceived service quality significantly leads to after-sales service satisfaction, which itself is a strong predictor of workshop loyalty. Moreover, workshop loyal customers are likewise significantly brand loyal. Finally, the influence of culture is empirically verified with the one exception of after-sales service satisfaction.

Industry players are seeking ways to reduce operational cost to sustain in a challenging economic trend. One key aspect is an energy cost reduction. However, implementing energy reduction strategy often struggle with obstructions, which slow down their realization and implementation. Discrete event simulation method is an approach actively discussed in current research trend to overcome such obstructions because of its flexibility and comprehensiveness. Meanwhile, in automotive industry, paint shop is considered the most energy consumer area which is reported consuming about 50%-70% of overall automotive plant consumption. Hence, this project aims at providing a tool to model and simulate energy consumption at paint shop area by conducting a case study at XYZ Company, one of the automotive companies located at Pekan, Pahang. The simulation model was developed using Tecnomatix Plant Simulation software version 13. From the simulation result, the model was accurately within ±5% for energy consumption and ±15% for maximum demand after validation with real system. Two different energy saving scenarios were tested. Scenario 1 was based on production scheduling approach under low demand situation which results energy saving up to 30% on the consumption. Meanwhile scenario 2 was based on substituting high power compressor with the lower power compressor. The results were energy consumption saving of approximately 1.42% and maximum demand reduction about 1.27%. This approach would help managers and engineers to justify worthiness of investment for implementing the reduction strategies.

The automotive electronic architectures have moved from federated architectures, where one function is implemented in one ECU (Electronic Control Unit), to distributed architectures, consisting of several multicore ECUs. In addition, multicore ECUs are being adopted because of better performance......, cost, size, fault-tolerance and power consumption. Automotive manufacturers use AUTomotive Open System ARchitecture (AUTOSAR) as the standardized software architecture for ECUs. With AUTOSAR, the functionality is modeled as a set of software components composed of subtasks, called runnables...

This commentary explores theoretical alternatives for viewing the problem identified by Volny Fages and Virginie Albe in their article entitled Social issues in nanoscience and nanotechnology Master's degrees: The socio-political stakes of curricular choices. An approach to social research is suggested that would render visible the associations maintaining the states of affairs depicted by Fages and Albe. In their research, Fages and Albe identified conceptions of the relationship between scientific endeavour and social concerns to be at the root of "choices" made by coordinators of Masters programs in nano science and technology in universities selected for their study. Albe and Fages, insiders in the sense that they take responsibility for a particular program within one such course, convey their belief that, "future scientists need to identify, accept and take on board the social responsibilities linked to their own practice of science, and to work collectively for a more democratic division of power regarding socio-technical choices". However, many of the Master's programs reviewed in their research were reported as providing limited opportunities for their students to critically engage with social aspects of scientific work. This commentary questions the notion of "choices" used in their research and proposes Actor-Network Theory as a theoretical framework open to the existence of various human and non-human agencies at work when a "choice" is made. The aim of the commentary is to further Fages and Albe's agenda by calling for understanding and ultimately a reassembling of the state of affairs in a way that would be acceptable to those invested.

Sports and orthopaedic physical therapists have long used a multitude of techniques in order to address pain and dysfunction associated with myofascial trigger points. One technique in particular has recently received overwhelming attention: trigger point dry needling (DN). Despite its efficacy and low risk, questions remain as to its effectiveness, safety, and whether the technique is within the scope of practice of physical therapists. Therefore, the purpose of this clinical commentary is to summarize the current literature related to the associated mechanisms of action of DN, the safety of DN, as well as to discuss relevant scope of practice concerns. 5.

The most important papers of Tony Hilton Royle Skyrme are collected in this volume which also includes commentaries by G Brown and other articles relating to the life and work of Tony Skryme, R Dalitz, E Witten and others. Skyrme's work was brilliant, profound and surprisingly useful. He provided an original solution to the problem of constructing fermions from bosons, formulating the topological soliton model of the nucleon. His two-parameter model of effective interactions in nuclei has yielded a remarkably accurate description of nuclear structure. His a-particle model of nuclei gave deep i
This paper is an author response to two commentaries on 'Defining Synaesthesia' (Simner, 2012) by David M. Eagleman ('Synesthesia in its protean guises', 2012), and Roi Cohen Kadosh and Devin B. Terhune ('Redefining synaesthesia?', 2012). Together with these authors, I seek to more closely examine existing criteria on which definitions of synaesthesia have been based. In particular, I focus on the fact (a) that existing definitions paint synaesthesia as an overly homogenous condition, (b) synaesthesia may have multiple neurological causes, and (c) synaesthetes and non-synaesthetes may lie on a continuum. ©2011 The British Psychological Society.
