This book discusses the various aspects of smart cities and their architecture along with the application of the latest technologies, including the Internet of Things (IoT) and artificial intelligence (AI). The concept of smart cities, their development, technological advancements, and issues related to them are discussed in detail.Smart Cities: Concepts, Practices, and Applications covers numerou
The impact of different spark designs on the ignition and combustion stability is studied using a 13-liter CNG fueled heavy duty spark ignited engine to search for the “optimal” spark design. Experimental results show that robust ignition can be achieved using a significantly shorter spark duration and lower energy than expected. A capacitive discharge ignition (CDI) system enabled to separately
OBJECTIVE: Emergency department length of stay (EDLOS) is linked to crowding and patient outcomes whereas worse prognosis in low socioeconomic status remains poorly understood. We studied whether income was associated with ED process times among patients with chest pain.METHODS: This was a registry-based cohort study on 124,980 patients arriving at 14 Swedish EDs between 2015 and 2019 with chest p
This study analyzes innovation activities in medium-technology sectors in Germany, Italy and Spain and checks whether cross-country similarities or differences prevail. The results have important implications for the Sectoral Systems of Innovation and the Distance-to-the-Frontier frameworks. While the Sectoral Systems of Innovation predicts the existence of technology-related similarities in innov
Data on net CO2 exchange from eight forests in Denmark, Sweden, Finland and Iceland were used to analyse which factors were controlling photosynthesis and respiration. The forests consisted of different species ranging in climatic condition from temperate to subarctic. Only well mixed conditions were analysed (u* > 0.3 m s(-1)). The parameters of a light response function showed strong seasonal va
Abstract Background: Current prognostic molecular markers for epithelial ovarian cancer (EOC) are insufficient. The aim of the current study was to investigate the role of Sox11 in EOC Methods: Using an in silico transcriptomic screen Sox11 was identified as a potential EOC biomarker. Sox11 protein expression was evaluated using immunohistochemistry (IHC) in 76 EOC cases, which were analyzed using
The relationship between requirements engineering and testing has been a key interest throughout my research career. It cannot be that requirements engineers are from Omicron Persei 7 and testers from Omicron Persei 9—we all live on the same planet. I’m happy to co-author this column with a former collaborator from a test automation EU project, now a manager at Ericsson. With this issue’s focus on
Despite the desire to utilize proactive safety metrics, research results indicate imbalances can arise between economic performance metrics and safety metrics. Imbalances can arise, first, because there are fewer proactive metrics available relative to the data an organization can compile to build reactive metrics. Second, there are a number of factors that lead organizations to discount proactive

Why is current capitalism unwilling (or unable) to shift its energy base from fossil fuels to renewable energy? Explanations such as information deficit, socially organized denials, or game-theoretical dilemmas are insufficient. Neither are the obstacles primarily technical or financial. Rather, the problems are related to social relations and capitalism as such. Four potential barriers to a renew
We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in th
Energy consumption reduction is today an important design issue for all kinds of digital systems. Offering both flexibility and efficient energy management, variable speed processor architectures are prefered for low energy consumption even in hard real-time systems. For this type of systems, the main approach consists in trading speed for lower energy while meeting all deadlines. For tasks with v
Four years have passed since January 1996 when retail competition was introduced in the Swedish electricity market. These years have been characterized by a rapid restructuring of the electricity supply industry through mergers and acquisitions, lower electricity prices, and a search for new marketing strategies in the competitive market. General trends and the results of two market surveys, under
The purpose of this study was testing and performance simulation of an innovative tracking hybrid solar system being developed by the Swedish Company Arontis. The Solar8 collector produces both electrical and thermal energy in one system. Its performance was compared with conventional photovoltaic panels and solar thermal collectors working side-by-side which are already on the market. The solar8
