Abstract in UndeterminedAn efficient technique is introduced to reduce mutual coupling between two closely spaced PIFAs for MIMO mobile terminals. The proposed mutual coupling reduction method is based on a T-shape slot impedance transformer and can be applied to both single-band and dual-band PIFAs. For the proposed single-band dual PIFAs, the 10 dB impedance bandwidth covers the 2.4 GHz WLAN ban
It is, with the thermal models used in today's building simulation progr¿rms,possible to calculate the major part of the heat transfer in a room with an ambientouter wall. However, there are some parameters these models calculatewith less or unknown accuracy: heat flows in poorly insulated walls or windows,heat flows in a room exposed to strong solar radiation, temperatures onthe inside of ambientAn ambient wall with a window were studied with both theoretical analyses and measurements performedunder conditions with natural climate. The method used wes to estimate the heat flow through wall and windowfrom measured temperatures and solar radiation. The longwave radiation was calculated from surface temperatures. The convective heat transfer was caculated as the difference between the heat f
Within a single region, it is possible to identify opposite changes in flow production. This proved to be the case for several basins in southeastern South America. It remains challenging to the causes this behavior and whether changes in streamflow will continue at current levels or decline in the coming decades. In this study, we used the Soil Water Assessment Tool to simulate monthly river disc
Sulfonate ester hydrolysis has been the subject of recent debate, with experimental evidence interpreted in terms of both stepwise and concerted mechanisms. In particular, a recent study of the alkaline hydrolysis of a series of benzene arylsulfonates (Babtie et al., Org. Biomol. Chem. 10, 2012, 8095) presented a nonlinear Brønsted plot, which was explained in terms of a change from a stepwise mec
CreditsEach course or programme is measured in credits, using the European Credit Transfer and Accumulation System (ECTS).60 ECTS credits are equal to the workload of a full-time student over one academic year (i.e. two semesters of study over 40 weeks).30 ECTS credits are equal to the workload of a full-time student over half an academic year (i.e. one semester of study over 20 weeks).One credit

Lack of courses in emergency medicine for doctors under training is currently a problem in Sweden. Only 10 percent will have these courses early under their internship. The University hospital in Malmoe has therefore decided to create a course for doctors under training and to offer it early in their education. The curriculum is based on a problem-based learning concept using a modified case metho
We introduce rigorous theory for deriving first and second order backpropagation methods for Deep Neural Networks (DNN) whilst satisfying existing theory in DNN optimization. We begin by formally defining a neural network with its respective components and state the first and second order chain rule with respect to its partial derivatives. The partial derivatives in the chain rule formula are rela
BACKGROUND: Definition of temporal serum proteome profiles after out-of-hospital cardiac arrest may identify biological processes associated with severe hypoxia-ischaemia and reperfusion. It may further explore intervention effects for new mechanistic insights, identify candidate prognostic protein biomarkers and potential therapeutic targets. This pilot study aimed to investigate serum proteome p
An integrated process for purifying a 6.1 kilo base pair (kbp) plasmid from a clarified Escherichia coli cell lysate based on an ultra/diafiltration step combined with polymer/polymer aqueous two-phase system and a new type of chromatography is described. The process starts with a volume reduction (ultrafiltration) and buffer exchange (diafiltration) of the clarified lysate using a hollow fibre me
Pålning är en typ av grundläggning lämplig för att grundlägga broar vid svaga markförhållanden. Att manuellt utforma en pålgrupp är en iterativ, tidskrävande process där snittkrafterna i pålarna måste verifieras för ett stort antal lastfall. Efter installationen kan pålarna dessutom ha nya positioner och kapaciteten måste verifieras igen. I detta projekt utvecklades en mjukvara för att automatiserFor bridges in weak ground conditions, piling is an appropriate type of foundation. To manually arrange the piles in a pile group is an iterative, time consuming process where the section forces in the piles must be verified for a large number of load cases. In addition, after installation, piles may have new positions and the capacity must be re-verified. In this thesis, a software was developed
The aim of this work was to develop a model of an integrated biomass-to-liquid process, consisting of hydrothermal liquefaction, evaporation, gasification and Fischer-Tropsch synthesis, using lignocellulosic forest residues as feedstock to produce hydrocarbons suitable for upgrade into drop-in biofuels. The energy, mass and carbon efficiencies that were achieved were 35%, 20% and 32%, respectively
Characterising the stop/start walking process of individuals in a crowded and congested space is an important consideration in modelling pedestrian movement. However, the reaction of pedestrians to speed changes, especially to the person in front, has not been fully characterised nor quantified for full adoption in computer models. This study, therefore, explored the different phases of the stop/s
We are currently in the process of evaluate and improve our education, and also keep in contact and build a network with our alumni. It would help us and future students, if you could take a few moments to complete the following questionnaire. Thank you for your contribution!
