Many of today’s software systems are created by leveraging ecosystems consisting of heterogeneous “complementors” and “hub” firms. In fact, the reliance on ecosystems is prevalent in the enterprise resource planning (ERP) domain, where larger ERP vendors form collaborative relationships with smaller industry-specific vendors to co-create value for themselves and their customers. However, value cre

This article argues that the increasing use of press images around 1900 contributed to the construction of the political persona of the British Statesman Joseph Chamberlain. These images fused scenes from his public and private life and, paradoxically, the new focus on his private characteristics reinforced his public role. His private life did not replace his public side, nor was the private unre

Samverkan mellan Arbetsförmedlingen och kommunerna lyfts av staten upp som en kungsväg till framgångsrik lokal aktiveringspolitik. Detta problematiseras med utgångspunkt i organisationernas konkurrerande logiker. Resultatet visar att samverkan kan reproducera en aktiveringspolitik som både upprätthåller en svag ställning för de arbetslösa och riskerar att leda till lokalt godtycke.

Eye trackers are applied in many research fields (e.g., cognitive science, medicine, marketing research). To give meaning to the eye-tracking data, researchers have a broad choice of classification methods to extract various behaviors (e.g., saccade, blink, fixation) from the gaze signal. There is extensive literature about the different classification algorithms. Surprisingly, not much is known a

Molecular motor-driven filament systems have been extensively explored for biomedical and nanotechnological applications such as lab-on-chip molecular detection or network-based biocomputation. In these applications, filament transport conventionally occurs in two dimensions (2D), often guided along open, topographically and/or chemically structured channels which are coated by molecular motors. H

A stract Significant advancements have been made towards exploitation of naturally available molecular motors and their associated cytoskeletal filaments in nanotechnological applications. For instance, myosin motors and actin filaments from muscle have been used with the aims to establish new approaches in biosensing and network-based biocomputation. The basis for these developments is a version

Exact cover is a non-deterministic polynomial time (NP)-complete problem that is central to optimization challenges such as airline fleet planning and allocation of cloud computing resources. Solving exact cover requires the exploration of a solution space that increases exponentially with cardinality. Hence, it is time- and energy consuming to solve large instances of exact cover by serial comput

Redox processes of oxide materials are fundamental in catalysis. These processes depend on the surface structure and stoichiometry of the oxide and are therefore expected to vary between surface facets. However, there is a lack of direct measurements of redox properties on the nanoscale for analysing the importance of such faceting effects in technical materials. Here, we address the facet-depende

Syftet med kapitel är att dels visa på potentialen i att studera även små till synes triviala detaljer i vardagliga objekt, dels att visa på betydelsen av det historiska sammanhanget för den semiotiska analysen. Detta har genomförts utifrån en analys av en för traditionell möbelproduktion vanligt förkommande teknik, nämligen sinkning, i tre olika historiska kontexter med såväl pre- som postindustr

The exploitation of ultrafast electron dynamics in quantum cascade lasers (QCLs) holds enormous potential forintense, compact mode-locked terahertz (THz) sources, squeezed THz light, frequency mixers, and comb-basedmetrology systems. Yet the important sub-cycle dynamics have been notoriously difficult to access in operationalTHz QCLs. Here, we employ high-field THz pulses to perform the first ultr

Markovian master equations provide a versatile tool for describing open quantum systems whenmemory effects of the environment may be neglected. As these equations are of an approximatenature, they often do not respect the laws of thermodynamics when no secular approximation isperformed in their derivation. Here we introduce a Markovian master equation that isthermodynamically consistent and provid
