Scheduling Macro-DataFlow Programs on Task-Parallel Runtime Systems

Though multicore systems are ubiquitous, parallel programming models for these systems are generally not accessible to a wide programmer community. The macro-dataflow model is an attractive stepping stone to implicit parallelism for domain experts who are not the target audience for explicit parallel programming models. We use Intel's Concurrent Collections (CnC) programming model as a concrete exemplar of the macro-dataflow model in this work. CnC is a high level coordination language that can be implemented on top of lower-level task-parallel frameworks. In this thesis, we study an implementation of CnC, based on Habanero-Java as the underlying task-parallel runtime system. A unique feature of CnC, first-class decoupling of data and control dependences, allows us to experiment with schedulers by taking these data and control dependences into account for better scheduling decisions. Our observations led to the proposal and implementation of a new task-parallel synchronization construct for Habanero-Java, namely Data-Driven Futures. We obtained two kinds of experimental results from our implementation. First, we compare the effectiveness of task scheduling policies for CnC programs. Secondly, we show that data-driven futures not only reduce execution time but also shrink memory footprint. In summary, this thesis shows a macro-dataflow programming model can deliver productivity and performance on modern multicore processors

Integration of lean approach with energy efficiency: Application in kitchenware manufacturing company

Energy efficiency in the industries is one of the leading problems of the 21st century. The main aim for the companies to deal with the energy efficiency paradigm is to save the resources in the manufacturing operations. Manufacturing opera-tions involve activities that creates wastes in any case; therefore, these wastes should be eliminated, or minimized as much as possible. In this paper, it is aimed to integrate the energy efficiency term with lean management principles. The barriers and the drivers of the energy efficiency was discussed, and the 8 wastes within lean perspective were translated into energy counterparts. 8 wastes of lean approach were defined as energy efficiency perspective, and used as criteria. The study will reveal the important criteria using Fuzzy Analytic Network Process (Fuzzy ANP) method to make impli-cations about how to eliminate these wastes

Decision making for risk evaluation: integration of prospect theory with failure modes and effects analysis (FMEA)

The aim of the present study is to overcome some of the limitations of the FMEA method by presenting a theoretical base for considering risk evaluation into its assessment methodology and proposing an approach for its implementation. Fuzzy AHP is used to calculate the weights of the likelihood of occurrence (O), severity (S) and difficulty of detection (D). Additionally, the Prospect Theory-based TODIM method was integrated with fuzzy logic. Thus, fuzzy TODIM was employed to calculate the ranking of potential failure modes according to their RPNs. In order to verify the results of the study, in-depth interviews were conducted with the participation of industry experts. The results are very much in line with Prospect Theory. Therefore, practitioners may apply the proposed method to FMEA. The most crucial failure mode for a firm’s attention is furnace failure followed by generator failure, crane failure, tank failure, kettle failure, dryer failure, and operator failure, respectively. The originality of this paper consists in integrating Prospect Theory with the FMEA method in order to overcome the limitations naturally inherent in the calculation of the FMEA’s Risk Priority Numbers (RPNs).N/

Operational excellence in a green supply chain for environmental management: a case study

Nowadays, organizations have started to become more conscious about the environment in their supply chain operations. The greening process has guided supply chain practices into new ways of thinking according to green standards. The assessment of the performance of green supply chain management (GSCM) requires a holistic view for the whole supply chain. In this context, given that becoming green in the operational side of activities is essential, the performance assessment of operational activities also requires a holistic view to be taken. In this paper, an attempt has been made to improve the performance of GSCM by examining and evaluating the green operational excellence of a hot dip galvanizing company. The framework includes several green operational excellence key criteria, namely, quality management, efficiency management, green production/manufacturing, eco-packaging, and green design. First, the weights of the criteria and the respective measurements were found by fuzzy analytic network process. Then, the overall operational performance score was found by a weighted scoring method. Finally, both managerial and theoretical implications were suggested according to the outcomes and findings of the case study

School Management and Moral Literacy: A Conceptual Analysis of the Model

Values Education Symposium -- OCT 26-28, 2011 -- Eskisehir, TURKEYWOS: 000305930000014The aim of this study is to analyze the moral literacy model developed by Tuana; discuss the superiorities and limitations, and constitute the theoretical conditions of a new model by utilizing previous researches and theories asserted about this subject. The model has stated that moral literacy is composed of three main components as ethics sensitivity, ethical reasoning skills and moral imagination, and these components involve at least three components, as well. In this study, it has been claimed that moral sensitivity includes both the cognitive and affective processes, and it has been suggested that a subcomponent about affect should be clearly included. It has been stated that Tuana's characterizing the moral intensity as a subcomponent of ethical sensitivity can be criticized; some researches asserted that moral intensity has relation with moral judgment and moral intention as much as it is related with moral sensitivity, and therefore; moral intensity can be regarded as a surrounding component effecting main components during ethical decision. In the model, it has been stated that handling virtue ethics, which is put forth as a criteria, within the moral judgment is open to criticism, as it is a concept more about behavior and fulfilling the action. It has been suggested that moral imagination, the third component of moral literacy, has a common quality effecting element of this process rather than effecting main components or subcomponents, like moral intensity. It has been determined that Tuana did not clearly state any component related to behavior, and so it has been suggested that moral intention, which is a component about action, can take place as a main component in this model.Eskisehir Osmangazi Uni

Untersuchung zur Penetration von topisch appliziertem Diclofenac-Natrium 4% Sprüh-Gel in Synovialgewebe, Synovialflüssigkeit und Plasma bei Patienten mit geplantem endoprothetischem Kniegelenksersatz

Diese Studie sollte das Penetrationsvermögen von lokal appliziertem Diclofenac Sodium Spray 4% Gel in das Synovialgewebe, die Synovialflüssigkeit und das Blutplasma bei Patienten mit Gelenkergu und geplantem endoprothetischem Gelenkersatz bei Gonarthrose klären. Hierzu wurden 39 Patienten mit geplantem Gelenkersatz in 2 Behandlungsgruppen mit jeweils 2-maliger oder 3-maliger Applikation von Diclofenac Sodium 4% Spray Gel über einen Zeitraum von 3 Tagen randomisiert. Acht Stunden nach der letzten PräparatAnwendung erfolgte die KnieOperation mit einer Konzentrationsbestimmung von Diclofenac im Synovialgewebe, der Synovialflüssigkeit und dem Blutplasma durch Flüssigkeitschromatographie. Die mediane DiclofenacKonzentration im Synovialgewebe war ca.10-20-fach höher (36.2 und 42.8 ng/g) als in der Synovialflüssigkeit (2.6 and 2.8 ng/mL)oder im Blutplasma (3.9 and 4.1 ng/mL) in beiden Behandlungsgruppen. Hierbei konnte jedoch keine Dosisabhängigkeit für ein Kompartiment oder Behandlungsgruppe festgestellt werden. Behandlungsabhängige Nebenwirkungen wurden in zwei Fällen in Form von Hautreaktionen beobachtet. Zusammenfassend ist Diclofenac Sodium 4% Spray Gel in der Lage die Haut lokal in wirksamen Mengen zu penetrieren und das gewünschte Zielgewebe zu erreichen. Die gemessenen Konzentrationen waren nicht dosis-abhängig und die Anwendung wurde in 97,4% der Patienten sehr gut vertragen. Somit stellt die topische Anwendung von Diclofenac eine sehr gute Alternative zur systemischen NSARTherapie in der initialen Behandlung der Arthrose dar
