There are various physical processes (such as mass, heat and momentum transport) integrated with catalytic chemical reactions in a methane steam reforming duct. It is often found that endothermic and exothermic reactions in the ducts are strongly coupled by heat transfer from adjacent catalytic combustion ducts. In this paper, a three-dimensional calculation method is developed to simulate and ana
Evidence supporting the benefits of exercise following the diagnosis of breast cancer is overwhelming and compelling. Exercise reduces the severity and number of treatment-related side effects, optimizes quality of life during and following treatment, and may optimize survival. Yet, exercise does not uniformly form part of the standards of care provided to women following a breast cancer diagnosis

Welding aerosols have been sampled in different size fractions using a moving stage cascade impactor. Sampling has been done for different welding methods and for varying welding parameters. The elemental composition of the different size fractions have been determined by Proton Induced X-ray Emission, PIXE, combined with a nuclear method for fluorine analysis. Results show maximum mass of most el
Welfare capitalism has developed in the context of rapidly expanding, fossil fuel-driven industrial economies. Faced with the urgent need for systematic changes of economic systems so that they stay within planetary limits, decoupling welfare from economic growth is an important task. This chapter introduces the concept of sustainable welfare, referring to welfare systems that prioritise the satis
Driving automation systems, including autonomous driving and advanced driver assistance, are an important safety-critical domain. Such systems often incorporate perception systems that use machine learning to analyze the vehicle environment. We explore new or differing topics and challenges experienced by practitioners in this domain, which relate to requirements engineering (RE), quality, and sys
In this introductory article, we explain the purpose of this special issue that is set up as a Festschrift in honour of the (editorial) work of BengtJohannisson. Inspired by Italo Calvino's Six Memos for the Next Millennium, the special issue is structured along six essays that are both commemorative and affirmative, that is we use the work of Johannisson to explore fresh waters and invent new pra
Many concepts for future generations of wireless communication systems use coherent processing of signals from many distributed antennas. The aim is to improve communication reliability, capacity, and energy efficiency and provide possibilities for new applications through integrated communication and sensing. The large bandwidths available in the higher bands have inspired much work regarding sen
This paper presents a simple and effective control solution to regulate temperature and humidity inside a greenhouse, which are the main climatic variables affecting crop growth and health. A multivariable control strategy with inverted decoupling is proposed in two schemes. The nighttime control scheme uses heating and dehumidification, and the daytime control scheme uses natural ventilation, deh
The current landscape of biopharmaceutical production necessitates an ever-growing set of tools to meet the demands for shorter development times and lower production costs. One path towards meeting these demands is the implementation of digital tools in the development stages. Mathematical modelling of process chromatography, one of the key unit operations in the biopharmaceutical downstream proc
