In anonymous online text-based counselling provided by social services, counsellors face specific communicative and professional challenges. Among other things, they need to ensure that they have understood the chat users correctly in order to provide relevant information and advice. The paper studies how counsellors check their understanding of users’ situations by using formulations, namely, sum

It is well known that reformulating the original problem can be crucial for the performance of mixed-integer programming (MIP) solvers. To ensure correctness, all transformations must preserve the feasibility status and optimal value of the problem, but there is currently no established methodology to express and verify the equivalence of two mixed-integer programs. In this work, we take a first s

The increased use of cloud and other large scale datacenter IT services and the associated power usage has put the spotlight on more energy-efficient datacenter management. In this paper, a simple model was developed to represent the heat rejection system and energy usage in a small DC setup. The model was then controlled by a reinforcement learning agent that handles both the load balancing of th

The adenosine analog 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB) was found to increase the production of hepatitis A (HAV) antigen in two monkey kidney cell lines (Frhk-4 and Vero cells). DRB, a known inhibitor of the synthesis of messenger RNA, caused moderate changes in cell morphology. However, Frhk-4 cells could be maintained for several weeks at 80 microM of DRB, the concentration

The momentum distribution of electrons from decays of heavy flavor (charm and bottom) for midrapidity |y|< 0.35 in p+p collisions at s=200 GeV has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over the transverse momentum range 0.3 < p(T)< 9 GeV/c. Two independent methods have been used to determine the heavy-flavor yields, and the results are in good agreement

The deregulation of the European transport market has been a controversial topic, characterised by a lack of facts and figures on the actual impact of the regulations. Given the crucial importance of road freight transportation to European society, and the lack of figures and control of foreign vehicles operating domestically in other countries, the purpose of this paper is to present a novel, inn

Performance modeling is an important topic in capacity planning and overload control for web servers. We present an M/G/1/K*PS queueing model of a web server. The arrival process of HTTP requests is assumed to be Poissonian and the service discipline is processor sharing. The total number of requests that can be processed at one time is limited to K. We obtain closed form expressions for web serve

We analyze the convergence behavior of iteratively decoded coupled LDPC codes from a complexity point of view. It can be observed that the thresholds of coupled regular LDPC codes approach capacity as the node degrees and the number L of coupled blocks tend to infinity. The absence of degree two variable nodes in these capacity achieving ensembles implies for any fixed L a doubly exponential decre

The present paper presents a rational expression for the initiation of motion for non-cohesive sediment under rough turbulent wave conditions. Previously proposed relationships for the initiation of motion are examined as well as laboratory measurements corresponding to fully rough turbulent boundary layers (which is normally the case under prototype conditions). By combining the modified Shields

Risk analysis to prevent the spread of infection in workplace-based activities Scenario: A co-worker needs to carry out certain work-related tasks in the workplace. How does she or he prevent the spread of Covid-19? For degree project work, the exemption application regarding teaching is used.

Detta examensarbete har utforskat relationen mellan arkitektur och dokumentation. Syftet har varit att undersöka vilka normer som finns i arkitekturens och stadsplaneringens tillvägagångssätt för att dokumentera platser och vilka sanningar dessa ger upphov till. Ambitionen har varit att se dokumentation i relation till plats och makt för att bättre förstå arkitektens roll som någon i position av aThis thesis have investigated the relationship between architecture and documentation. The aim have been to study what norms that exist in architecture’s and city planning’s approaches for documenting sites and what types of truths they help create. The ambition have been to see documentation in relation to site and power to better understand the architect’s role as someone in a position to interp

The fatigue behavior of laminated veneer lumber (Douglas-fir) subjected to shearstress has been studied. The static shear strength of specimens, 37 by 102 by 406 mm was established through a three point bending test over a span of 305 mm. Four series of specimens were subjected to a cyclic load history with peak loads ranging from 95 to 80 percent of the static strength. The duration of each load

This paper studies the impact of corporate income taxation on leverage ratios (debts as a share of total assets) in the banking sector across 102 countries for the period 2012-2021, aiming to replicate the 2013 IMF paper ‘Taxation, Bank Leverage, and Financial Crises’ by Keen, De Mooij and Orihara. With a sample of 5,829 banks, a system GMM is used, together with a fixed effects model to compare t

Cellular radio based localization can be an important complement or alternative to other localization technologies, as base stations continuously transmit signals of opportunity with beneficial positioning properties. In this paper, we use the long term evolution (LTE) cell-specific reference signal for this purpose. The multipath component delays are estimated by the ESPRIT algorithm, and the est

A project on the states and changes in Swedish primary forests Primary forests are forests with minimal direct human impact. Nowadays these forests are rare relics in the landscape that tell a valuable tale of how our ecosystems would have looked in the absence of land use. This page describes our work on primary forests over time, activities and publications. Mapping primary forests in Sweden In

This study aims to examine how support persons at anonymous support chat services describe their role in conversations with children who are abused by relatives and how they use their discretion to fulfil this role. Semistructured interviews were made with five support persons working at different anonymous support chats in Sweden. The analysis of data was guided by an interactionist perspective a
