A mathematical programming approach for resource allocation of data analysis workflows on heterogeneous clusters

Scientific communities are motivated to schedule their large-scale data analysis workflows in heterogeneous cluster environments because of privacy and financial issues. In such environments containing considerably diverse resources, efficient resource allocation approaches are essential for reaching high performance. Accordingly, this research addresses the scheduling problem of workflows with bag-of-task form to minimize total runtime (makespan). To this aim, we develop a mixed-integer linear programming model (MILP). The proposed model contains binary decision variables determining which tasks should be assigned to which nodes. Also, it contains linear constraints to fulfill the tasks requirements such as memory and scheduling policy. Comparative results show that our approach outperforms related approaches in most cases. As part of the post-optimality analysis, some secondary preferences are imposed on the proposed model to obtain the most preferred optimal solution. We analyze the relaxation of the makespan in the hope of significantly reducing the number of consumed nodes

Towards sustainable water use in industry: a case study of the oil refinery industry in Kazakhstan

The concept of “Sustainable water use” (SWU) aims to assure three pillars of sustainability related to the water sector: the social, environmental, and economical. Industrial development, especially in developing countries, requires an adequate response, as industrial activities are recognized as one of the major sources of water pollution, what leads to deterioration of environmental safety and wellbeing of the society. This thesis aims to understand to what extent the water use in the oil refinery industry in Kazakhstan is sustainable and to assess its impacts on the environment. A system approach was used to evaluate the current status of legislation, the treatment methods, the discharge process, and the effect on the environment in the sector. The weakness of the existing framework was identified by its lack of unified and transparent legislative standards for treatment processes, wastewater quality, and assessments of groundwater contamination with potential negative impact on public safety. Analysis of chemical characteristics of groundwater contamination, based on a seven-year monitoring program from one of the refineries, showed that groundwater has been affected, containing anthropogenically and naturally occurred contaminants, e.g. average exceedance for total petroleum hydrocarbons was 4 times, for total dissolved solids - 5 times, for chlorides - 9 times, for sodium - 6 times and total hardness was more than 6 times compared with World Health Organization and Kazakhstani standards. The analysis made it possible to specify the contribution of each contaminant to the overall pollution and to identify the most polluted sites. These pollutants are likely spreading towards areas with substantial groundwater use. The following investigation included performance of potential spreading of the TPH plume, based on historical observations. The results showed that zone at 2-6 km downstream the source of pollution could be affected by contaminated water, where concentrations of TPH exceeded permissible value. Based on performed investigations, this study highlights importance of implementation of suitable legislative standards with requirements for efficient water-saving techniques. Comparison with developed countries showed that Principles of Circular Economy (CE) (reduce pollution and reuse water) have been neglected in Kazakhstan. However, these principles have a potential to become a response to existing pressure of industrial activities and to achieve Sustainable Development as Driving force. Implementation of the CE for refineries in Kazakhstan requires firstly, the usage of advanced wastewater treatment techniques, and secondly, the introduction of the optimization scheme for water reuse, where regeneration units are established after each technological unit. Establishing criteria for water fees, wastewater quality, and recipients’ characteristics should follow respective and fair practices of the Environmental Impact Assessment, instead of looking for legislative loopholes. These practices include a detailed assessment of a real level of effluents’ toxicity and strict requirements to avoid the transfer of pollutants from one environmental media to another. Also, it is strongly recommended to update the list of contaminants for operational monitoring with inclusion of specific indicators of toxicity, such as PAHs, BTEX and others. It will let to understand the real harm caused by the ineffective systems of wastewater treatment and disposal from oil refineries in Kazakhstan.This thesis can be used as a trigger to drive and engage all stakeholders into a transparent dialogue about potential consequences of non-sustainable wastewater management in the industry in Kazakhstan. The potential actions might include development of new efficient monitoring programs, stimulation the industry to innovative and water-saving treatment methods, and a creation of a site remediation program

Proceedings of the GPEA Polytechnic Summit 2022: Session Papers

Welcome to GPEA PS 2022 Each year the Polytechnic Summit assembles leaders, influencers and contributors who shape the future of polytechnic education. The Polytechnic Summit provides a forum to enable opportunities for collaboration and partnerships and for participants to focus on innovation in curriculum and pedagogy, to share best practices in active and applied learning, and discuss practice-based research to enhance student learning. This year a view on the aspects of applied research will be added. How to conduct research in a teaching first environment and make use of this. Which characteristics of applied research are important to be used in teaching and vice versa?The Summit will – once again - also provide an opportunity to examine the challenges and opportunities presented by COVID-19 and will offer us all an opportunity to explore the ways in which we can collaborate more effectively using our new-found virtual engagement skills and prepare for a hybrid future. PS2022 Themes: Design (Programmes, Curriculum, Organisation);Practice-Based Learning;Applied Research; Employability and Graduate Skills; Internationalisation, Global Teaching & Collaboration and Sustainability Theme

Responsible Management Education

The ebook will be Open Access and made available on publication. Written by many of the key influencers at the Principles for Responsible Management Education (PRME), the book focuses on advancing sustainable development into education, research and partnerships at higher education institutions and, specifically, at business schools, with the purpose of educating responsible leaders for today and tomorrow. The book serves as a concrete source of inspiration for universities and other stakeholders in higher education on structures, processes and content for how to advance responsible management education and sustainable development. It articulates the importance of key themes connected with climate change, gender equality, anti-corruption, business for peace, anti-poverty and other topics that are related to the Sustainable Development Goals (SDGs). The book emphasizes the significance of local–global interaction, drawing on local action at management schools in combination with global knowledge exchange across the PRME community. In addition, the book clearly demonstrates the background, key milestones and successful achievements of PRME as a global movement by management schools in collaboration with a broader community of higher education professionals. It exemplifies action in various local geographies in PRME Chapters, PRME Working Groups and the PRME Champions work to advance responsible management education. The authors of the book are all globally experienced deans, professors, educators, executives and students with a global outlook, who are united to advance responsible management education locally and globally. The book will be invaluable reading for university leaders, educators, business school deans and students wanting to understand and embed responsible management education approaches across their institutions and curricula
