PurposeThe purpose of this paper is to study a class of issues that in spite of recognised needs and explicit managerial demands have proven hard to have “stick” in organisations (information security is used as an example). It offers a theory-driven rationale why superficially different issue areas can indeed be considered as instances of the identified class, and builds on complexity leadership
With the promise of increased responsiveness and robustness of the emerging 5G technology, it is suddenly becoming feasible to deploy latency-sensitive control systems over the cloud via a mobile network. Even though 5G is herald to give lower latency and jitter than current mobile networks, the effect of the delay would still be non-negligible for certain applications.In this paper we explore and
In this paper we address Industrial IoT control applications which are safety-critical and real-time, and which have very low latency and jitter requirements. These control applications are virtualized as software tasks running on a Fog Computing Platform that brings computing and deterministic communication closer to the edge of the network, where the industrial "things" are located. Due to the d
Modern control algorithms are frequently implemented in a distributed and decentralized way. Multiple fog devices communicate using paradigms borrowed from the Internet-of-Things. These control infrastructures are vulnerable to security threats. This position paper describes these threats and sketches future research on how to mitigate the security concerns that a modern distributed control infras
We consider the problem of feasible coordination control for multiple homogeneous or heterogeneous mobile vehicles subject to various constraints (nonholonomic motion constraints, holonomic coordination constraints, equality/inequality constraints etc). We develop a general framework involving differential-algebraic equations and viability theory to describe and determine coordination feasibility
Nineteenth-century British philanthropic ideas were implemented in Sweden through the agency of translation. The present investigation of translation as a form of nineteenth-century social-reform activism takes the form of a case study of the Swedish translation of two texts by British social purity campaigner Ellice Hopkins (1836–1904).

Stereo rendering for 3D displays and for virtual reality headsets provide several visual cues, including convergence angle and high- light disparity. The human visual system interprets these cues to estimate surface properties of the displayed environment. Naïve stereo rendering effectively doubles the computational burden of image synthesis, and thus it is desirable to reuse as many computa- tion
Devices sharing a network compete for bandwidth, being able to transmit only a limited amount of data. This is for example the case with a network of cameras, that should record and transmit video streams to a monitor node for video surveillance. Adaptive cameras can reduce the quality of their video, thereby increasing the frame compression, to limit network congestion. In this paper, we exploit
The ever increasing number of connected devices has lead to a metoric rise in the amount data to be processed. This has caused computation to be moved to the edge of the cloud increasing the importance of efficiency in the whole of cloud. The use of this fog computing for time-critical control applications is on the rise and requires robust guarantees on transmission times of the packets in the ne
PurposeThis paper investigates and evaluates the temperature performance of cold food supply chains (FSCs) in relation to product shelf life in order to provide suggestions for food waste mitigation and food safety management in FSCs. Design/methodology/approachField tests were conducted to collect temperature data from Swedish FSCs, from production to retail cold storage, and during retail displa
In this paper, we consider positioning with observed-time-difference-of-arrival (OTDOA) for a device deployed in long-term-evolution (LTE) based narrow-band Internet-of-things (NB-IoT) systems. We propose an iterative expectation- maximization based successive interference cancellation (EM-SIC) algorithm to jointly consider estimations of residual frequency- offset (FO), fading-channel taps and ti
Pervasiveness and complexity of modern software are challenging engineers to design applications able to guarantee the desired quality of service despite unpredictable runtime variations in their execution environment. A variety of techniques have been proposed in the last year for the design of self-adaptive applications; however, most of them is tailored to specific applications or can provide l
Agricultural intensification and the subsequent fragmentation of semi-natural habitats severely restrict pollinator and pollen movement threatening both pollinator and plant species.

Douglas-Rachford splitting and the alternating direction method of multipliers (ADMM) can be used to solve convex optimization problems that consist of a sum of two functions. Convergence rate estimates for these algorithms have received much attention lately. In particular, linear convergence rates have been shown by several authors under various assumptions. One such set of assumptions is strong
Denna uppsats syftar till att undersöka i vilken utsträckning arbetstidslagstiftningen i Thailand och Sverige skyddar rätten till decent working time för hushållsarbetare. För att uppnå detta jämförs arbetstidslagstiftningen i de två länderna med hur decent working time definieras inom den internationella arbetsrätten. Denna analys utgör grunden för en diskussion om arbetstidsregleringen för hushåThis paper explores the extent to which working time legislation in Thailand and Sweden protects the right to decent working time for domestic workers. This is examined through a comparative analysis of the national working time legislation in the two countries and the parameters of decent working time established in international labor law. This is the basis for a subsequent discussion on the re
Denna uppsats behandlar det svenska naturskyddets rättsutveckling från de första naturskyddslagarnas tillkomst i början av 1900-talet fram till idag. Uppsatsens syfte är att undersöka naturskyddslagstiftningens utveckling vad gäller innehåll, motiv och bakomliggande miljöetisk natursyn. Undersökningen påvisar en rättsutveckling där lagstiftningen fått en ökad omfattning och högre ambitioner. Från
