Kazakhstan is facing increasing water scarcity due to climate change and transboundary international water diversions. For this reason, low-quality water with high mineral content needs to be increasingly used in the future. A way to improve water quality for consumptive use is membrane treatment technology. In view of this, we investigated a new type of synthetic spatial-globular structure (SGS)
Weather impacts several aspects of our daily life, of which the way we travel is one. The relationship between weather phenomena and ridership of trains has not received much attention previously. The study we present here aims to understand the impact of temperature, wind, and precipitation on passenger volumes for commuter trains. To do so we make use of automatic passenger count and weather dat
We have developed a sampling method for beamline simulations for the proposed NNBAR experiment at the European Spallation Source. The method is based on probability density evaluation and duct source biasing and enables the simulations of the entire NNBAR beamline with high statistics while also preserving correlations of the neutron tracks. Future efforts will focus on employing these methods for
This paper presents a neural network based semantic plane detection method utilizing polygon representations. The method can for example be used to solve room layout estimations tasks and is built on, combines and further develops several different modules from previous research. The network takes an RGB image and estimates a wireframe as well as a feature space using an hourglass backbone. From t
To complete a new Swedish railway line in a much shorter timeframe than today, alter natives to the traditional methods need to be explored. One option is the use of prefabricated concrete slabs elevated on piers, analogous to the concept used in China for building new railways in record time (He et al., 2017). The method has the advantage of directly tackling the barrier effects exhibited by trad
This paper focuses on how one can relate management thinking/practices to entrepreneurial processes in the context of formal organization. In order to do this we develop a number of related 'spatial concepts' providing us with the possibility of describing entrepreneurship as a 'creation and use of space for play/innovation'. Using concepts of space, the managerial and the entrepreneurial dimensio
This paper reports the work on implementing a parallel version of Pascal on a small scale multiprocessor computer. A few simple primitives were included to support parallel programming. The code generation, linking and loading procedures are described. An overview of the hardware is included. Finally some programming experience with the system is reported.
A bilinear system model of a continuous tank reactor from a biotechnology application (F. Mandenius et al., 1987) is studied. The concentrations of the substrate sugar and the product ethanol were measured on-line and utilized to control the flow-rate through the fermenter. The system can be integrated analytically making it possible to describe the reachable sets. Limited controllability is found
Composition is a practice of key importance in software engineering. When real-time applications are composed it is necessary that their timing properties (such as meeting the deadlines) are guaranteed. The composition is performed by establishing an interface between the application and the physical platform. Such an interface does typically contain information about the amount of computing capac
Purpose The aim of this paper is to provide insights into, and perspectives on, the transformation of mindsets for logisticians. We argue that by exploring paradoxes inherent in the efficiency-focused paradigm of today, a strategic mindset can emerge in which central logistics management issues can be addressed, understood, and dealt with in order to enhance supply chain effectiveness and innovati
The direct problem of time dependent electromagnetic scattering in the dispersive sphere is solved by a wave splitting technique. The electric field is expanded in a series involving vector spherical harmonics, leading to a system of wave equations for each term. These systems are reduced to scalar wave equations for each term, which are solved via reflection operators. Some preliminary numerical
