AbstractWastewater systems in developed cities contribute significantly to public health. The related systems are energy and resource intensive and do not recover nutrients in an efficient and effective way. Separating wastewater to greywater and blackwater at the source and exploiting organic municipal solid waste as an additional feed to an adjunct biogas plant could support efforts to make use of the potentials to reduce the environmental impacts, to increase the energy efficiency of winning nutrients, and to implement an additional, locally available energy source. However, the implementation of such systems is seen as expensive.The overarching aim of the paper is to analyze the eco-efficiency of transforming the current separately organized wastewater-energy-waste systems to an integrated one. The study differs between three system alternatives. The least invasive system change assumes a separation of wastewater at the source without a complete overhaul of the current system; the most elaborated one takes the current wastewater system fully out of operation. The reference for the current system is the existing system of a German medium-sized urban neighborhood. The analysis considers the eco-efficiency of two resource-related (fossil and metal depletion) and three emissions-related (climate change, photochemical oxidant formation and terrestrial acidification) impacts.Under the conditions of the settlement investigated, a transformation to the system alternatives will generate in all cases a weak eco-efficiency, i.e. the higher costs of implementing a new system counteracts with the noteworthy environmental improvement. Of the three options, the most elaborated one sees the best performance.

Abstract The 74th step of "100 Concrete Step of Nation Plan" initiated by the first president of the Republic of Kazakhstan (RoK) Nursultan Nazarbayev states that Kazakhstani reserves reporting system must be changed to the international standards. One of them actively proposed is the SPE-PRMS. Therefore, the main goal of the paper is to show challenges of the transition, discuss possible problems, their solution and, eventually, advantages for the companies. In the paper the main aspects of the current State Committee of Reserves (SCR) system or well-known as GKZ system inherited from the Soviet system and used in Kazakhstan are reported. Especially, we try to highlight the reserves categories of A, B, C1 and C2 and their impact on further field development in details. Also SPE-PRMS and SEC rules are shown in terms of differences and similarities with the current system. Importantly, authors demonstrate how the SPE-PRMS standards are wide-spread around the globe. Finally, details of planned shift, some recommendations and simplification of reporting process are exhibited. As the result of the study the following points are investigated. Firstly, what will be with reports just recently approved by the SCR. Especially, for the big fields whose preparation takes up to several years. Secondly, what the frequency is for the reporting. Thirdly, whether the reports will be handled through several approval stages or just submitted. Moreover, how close to SPE-PRMS the new system should be adopted taking into account Kazahstani realities and if the reports should be composed in English along with Russian, since the main purpose of the transition is to be clear and transparent for the foreign investors. Otherwise, unfamiliar language and big deviation from the well-known standards may ruin the efforts. Despite the complexity of these issues the benefits of the new system are obvious and there are several reasons. The main advantage is that the SPE-PRMS is all about economically recoverable reserves without any ties with fixed recovery factor. In addition, report is done in short time and less volume. Finally, if the norm of the report's submission without going to tedious approval process is accepted, that will ease work of the subsoil users’ because it accelerates further preparation of field development project. The study is done due to recent changes of the RoK subsoil usage regulations, where the requirement for reserves reporting system's transition to the new international standards is mentioned. However, the issue is not much highlighted in technical publications from the operating companies’ point of view. Thus, having experience with GKZ, SPE-PRMS and SEC systems the authors take this opportunity to show challenges and benefits of the decision.

Sales Analysis Using Forecasting Method aims to improve effectiveness and efficiency that facilitates companies in business transaction processes, improve the delivery of information quickly, accurately, and transaction data well and minimize errors. The method used in the presentation of this scientific work is by using a forecasting method which helps determine the approximate stock of goods to come. With 3 forecasting modules are: Moving Average, Weighted Moving Average, Trend Projection is used to perform the forecasting process of the upcoming stock of goods. Can solve problems that exist in the current system so that it can help in improving its services by calculating the stock and helping by determining the average data that has been linked to the forecasting module whose results can be concluded through reports per period. It can be concluded that the results of implementing this new system can help companies in recording each transaction that occurs becomes more efficient and effective, so that it can overcome the problems that exist in the current system. With this we can predict the current flow of goods that have been calculated based on 3 (three) modules that have connections with the system

This chapter provides a brief overview of systems theory and suggests that product designers could use systems theory and systems dynamics models to improve our understanding of complex Product Design research problems, to anticipate how and where changes in these dynamically evolving systems might occur and how they might interact with the current system to produce a new system with new behaviors, and to identify leverage points within the system where potential policy or design process changes might be introduced to produce effective solutions to these problems with minimum policy resistance. By investigating the current and future trends of the application of systems theory in Product Design research, this chapter invites multidisciplinary discussions of these topics.

It has been acknowledged, in Australia and beyond, that existing urban water systems and management lead to unsustainable outcomes. Therefore, our current socio-technical systems, consisting of institutions, structures and rules, which guide traditional urban water practices, need to change. If a change towards sustainable urban water management (SUWM) practices is to occur, a transformation of our established social-technical configuration that shapes the behaviour and decision making of actors is needed. While some constructive innovations that support this transformation have occurred, most innovations remain of a technical nature. These innovative projects do not manage to achieve the widespread social and institutional change needed for further diffusion and uptake of SUWM practices. Social theory, and its research, is increasingly being recognised as important in responding to the challenges associated with evolving to a more sustainable form of urban water management. This paper integrates three areas of social theories around change in order to provide a conceptual framework that can assist with socio-technical system change. This framework can be utilised by urban water practitioners in the design of interventions to stimulate transitions towards SUWM.

In five years at Pinsents I have seen three different library management systems. Our current system, OLIB7, has been in situ since September 2002 and for the most part is working well. But why have we had three in such a short space of time? Why did we choose OLIB7? And is implementing a new system really all that bad?

This paper describes a major program of research by the Commonwealth Scientific and Industrial Research Organization (CSIRO) into urban water, wastewater and stormwater services. The intent of the program has been to identify opportunities for achieving more sustainable urban water services. The term “sustainable” has been interpreted to mean improvements in environmental and economic performance of systems which maintain inter- and intragenerational equity. It is evident from the conclusions of the feasibility stage of the Urban Water Program that such opportunities exist, particularly with regard to the design and configuration of water and wastewater systems. The structure of the UWP is described and examples of critical outcomes given.
