The development of surfactant-templated mesoporous films grown at the air/water interface was investigated using specular and off-specular X-ray reflectivity techniques. The samples were prepared in acidic conditions using cetyltrimethylammonium bromide (CTABr, 0.075 M) and different concentrations (0.27-0.88 M) of tetramethyloxysilane (TMOS). At CTABr/TMOS molar ratio between 0.277 and 0.093, the
Order Picking in warehouses is often optimized using a method known as Order Batching, which means that one vehicle can be assigned to pick a batch of several orders at a time. There exists a rich body of research on Order Batching Problem (OBP) optimization, but one area which demands more attention is computational efficiency, especially for optimization scenarios where warehouses have unconvent
Poor water services in developing countries after national conflict as a result of institutional setups and devastating infrastructures. This study assesses how institutional arrangements have affected the poor water services in Somalia, through thematic analyses. The huge gap in the literature about Somalia highlights the significant need of such research works and the originality of this paper.
Utilities, such as steam and cooling water, are often shared by several production areas at an industrial site. In order to minimize the loss of revenue due to disturbances in the supply of utilities, the optimal supply of utilities to different areas has to be determined. It is not evident how utility resources should be divided, as both buffer tank levels, the connections between areas, and the
In this work, we present a novel self-aligned gate-last fabrication process for vertical nanowire metal-oxide-semiconductor field-effect transistors. The fabrication method allows for exposure dose-defined gate lengths and a local diameter reduction of the intrinsic channel segment, while maintaining thicker highly doped access regions. Using this process, InAs nanowire transistors combining good
The purpose of this study is to increase knowledge about how the corona pandemic affects organizations that work with the homeless people. To examine this I have conducted interviews with the professionals working with the group. I have used qualitative methods in the form of semi-structured interviews to examine my research questions. I have interviewed three professionals working for two differe
Medverkansansvar inträder när flera personer tillsammans utför otillåtna gärningar. Rättsläget är i stora delar oreglerat, men hänförs till 23 kap. 4 § Brottsbalken (BrB). Om alla personer agerar tillsammans och i samförstånd och utför lika stora delar av gärningen döms de alla som medgärningsmän. Den som inte är gärningsman, men ändå främjat brottet, bedöms som anstiftare eller medhjälpare. GenomThe legal structure of Swedish criminal law when a group of people commits unlawful acts (responsibility for complicity) is largely unregulated but is based in section 4, chapter 24 of the Swedish Penal Code. If these persons perform equal actions in the act and act together and in consensus, they are all liable as co-perpetrators. A person who is less involved, but who has promoted the act, can b
We observe that, while predicting returns remain difficult and uncertain, volatility exhibit more persistence and predictability due to well-known patterns such as volatility clustering (Mandelbrot, 1967). We test whether short-horizon volatility forecasts can be used to time leverage in a passive index strategy so as to mitigate the growth penalty from volatility drag in leveraged exchange-traded
Objective: To explore diagnoses of postpartum haemorrhage following vaginal birth, in relation to socio-demographic and obstetrical data from women who gave birth at term, in Sweden, during the years 2005–2015. Study design: A register-based cohort study was carried out, describing and comparing socio-demographic variables, obstetric variables and infant variables in 52 367 cases of diagnosed post
Objectives: To define requirements that condition trust in artificial intelligence (AI) as clinical decision support in radiology from the perspective of various stakeholders and to explore ways to fulfil these requirements. Methods: Semi-structured interviews were conducted with twenty-five respondents—nineteen directly involved in the development, implementation, or use of AI applications in rad
Den 1 juli 2020 infördes hedersmotiv som försvårande omständighet i 29 kap. 2 § 10 p. BrB. Lagändringen syftade till att tydligare markera brottslighetens särskilda klandervärdhet när gärningen begåtts med hedersmotiv och att möjliggöra ett strängare straff för sådan brottslighet. Mot denna bakgrund undersöker uppsatsen om bestämmelsen har fått det genomslag i rättstillämpningen som lagstiftaren aOn 1 July 2020, honour motives were introduced as an aggravating circumstance in Chapter 29, Section 2, point 10 of the Swedish Criminal Code. The amendment aimed to more clearly emphasise the particular blameworthiness of criminal conduct when an offence is committed with an honour motive and to enable harsher punishment for such crimes. Against this background, this essay examines whether the pr
The effect of friction between the dowel and the surrounding timber was studied for single dowel-type joints. The joints tested were divided into two groups of joints, where the surface of the dowels differed. For the first group, the dowels had a smooth surface and for the second group the dowels had a rough surface. A contactfree measurement technique was used in the experimental investigatio
Confidential computing allows processing sensitive workloads in securely isolated spaces. Following earlier adop- tion of process-based approaches to isolation, vendors are now enabling hardware and firmware support for virtualization-based confidential computing on several server platforms. Due to variations in the technology stack, threat model, implemen-tation and functionality, the available s

Mathematical optimization is becoming increasingly important for engineering in general and control in particular. This thesis deals with numerical methods, primarily direct collocation, and symbolic methods, primarily block-triangular ordering and tearing, for numerical solution of general dynamic optimization problems involving dynamical systems modeled by large-scale differential-algebraic equa
Poland’s List of Monarchs and the La Fontaine Fable in a Moralizing Work of Swedish Eighteenth-Century Literature The paper elucidates a work of Early Modern Swedish literature, entitled Polska Kongars Saga och Skald [Saga and Song of Polish Kings] and published anonymously at the royal printing house in Stockholm in 1736. This book is remarkable in several respects. In 51 chapters it portrays th
Feedback in server systems has during last years gained much interest in order to fulfill still increasing demands on performance and optimization regarding, for example, quality of service (QoS) requirements. In this paper we expand a previously published feedback–based prediction scheme for controlling a single server queue together with a new control strategy. These control structures have the
Hjalmar Söderberg (1869–1941) published some seventy short stories in five collections, Historietter (1898), Främlingarna (1903), Det mörknar öfver vägen (1907), Den talangfulla draken (1913) and Resan till Rom (1929). The present study explores Söderberg’s short fiction from a genre-historical and genre-theoretical perspective. It investigates the characteristic traits of Söderberg’s short-story
