Given the growing importance of bike-sharing systems nowadays, in this paper we suggest an alternative approach to mitigate the most crucial problem related to them: the imbalance of bicycles between zones owing to one-way trips. In particular, we focus on the emerging free-floating systems, where bikes can be delivered or picked-up almost everywhere in the network and not just at dedicated dockin
In this work we present an integrated system for whole chromosome analysis of single bacterium. Using whole genome barcoding techniques, which offer direct and rapid microscopic visualization of the entire genome in one field-of-view, we aim to rapidly identify individual bacterium. We are developing our device to achieve the crucial, and difficult process of isolating a bacterium, removing the DN
In this paper, a new approach to designing beamformers for voice control device is proposed. It is well-known that under a strong near-field noise with low signal-to-noise ratios (SNR), the performance of speech recognition is deteriorated significantly. However, designing the beamformer for enhancing speech recognition is a slow process and might not be adapted. easily to the changing noise envir
Nonlinear optical methods have become ubiquitous in many scientific areas, from fundamental studies of timeresolved electron dynamics to microscopy and spectroscopy applications. They are, however, often limited to a certain range of parameters such as pulse energy and average power. Restrictions arise from, for example, the required field intensity as well as from parasitic nonlinear effects and
This document presents the results of a literature review performed in order to assess the suitability of different evacuation modelling tools for the calculation of evacuation times and assessment of fire safety in underground physics research facilities. This document is part of the research collaboration between Lund University and the European Organization for Nuclear Research (CERN), concerni
In this paper, a novel hard-output detection algorithm for the complex multiple-input multiple-output (MIMO) detectors is proposed, which results in a significant throughput enhancement, a near-ML performance, and an SNR-independent fixed-throughput. Moreover, a high-throughput VLSI implementation is proposed, which is based on a novel method of the node generation and sorting scheme. The proposed
A study on characteristics of currents and mixing in a shallow ice‐covered Russian lake is presented. The current velocity data are separated into four main components, mean velocity, uninodal longitudinal and transverse seiche currents, and “high”‐frequency velocity fluctuations, using digital filters. The analysis of components shows that mean currents are most pronounced in early winter and are
Introduction: Osteoarthritis (OA) is one of the most common causes of knee pain, and the most common form ofarthritis. It causes pain and disability, and there is currently no cure. Recent research in knee OA highlights therole of the meniscus in OA pathology. In this thesis, the overall aim was to study the proteome and microstructureof the human meniscus, both in healthy subjects and OA patients
Since 2004 the free-electron laser FLASH at DESY has been operated in the Self-Amplified Stimulated Emission mode (SASE), delivering gigawatt pulses with wavelengths between 6.5 nm and 40 nm in the femtosecond domain. In 2009 DESY installed an additional radiofrequency module for controlling the phase space of the electron bunches that gives the possibility to generate bunches with high peak curre
In this paper, we argue that the legitimation of killing in war is not simply formed by adherence to certain legal requirements that exist apart from and prior to war; instead, we suggest, the law of armed conflict in itself cannot but operate through admitting certain materials onto the battlefield as distinctively legal materials. Using the theory of legal materiality, we show that the military
We demonstrate for the first time a technology which allows the monolithic integration of both p-Type (InAs-Si) and n-Type (InAs-GaSb) heterojunction Tunnel FETs (TFET) laterally on a Si substrate. The lateral heterojunction nanowire (NW) structures are implemented using top-down CMOS-compatible processes combined with Template-Assisted Selective Epitaxy (TASE) [1] of the III-V materials. Sub-40nm
Wohlers Associates, Inc., recognized widely as the leading consulting firm and preeminent authority on additive manufacturing and 3D printing worldwide—terms that are used interchangeably—today announced the publication of the Wohlers Report 2016. The 2016 edition marks the 21st consecutive year of its availability. According to Wohlers Report 2016, the additive manufacturing (AM) industry, consis
The aim of this study is to explore the possibility of identifying speaker stance in discourse, provide an analytical resource for it and an evaluation of the level of agreement across speakers in the area of stance-taking in discourse. We explore to what extent language users agree about what kind of stances are expressed in natural language use or whether their interpretations diverge. In order
Writers typically spend a certain proportion of time looking back over the text that they have written. This is likely to serve a number of different functions, which are currently poorly understood. In this article, we present two systems, ScriptLog+ TimeLine and EyeWrite, that adopt different and complementary approaches to exploring this activity by collecting and analyzing combined eye movemen
The degradation of hydroxyethyl cellulose (HEC) using sodium persulfate (NaPS) as free radical generator was studied at 60, 70 and 80 degrees C with different NaPS/HEC ratios. During the degradation reaction samples were withdrawn at regular intervals. The amount of persulfate remaining was analyzed by titration and the evolution of the HEC molecular weight distribution and viscosity was followed
