A pilot plant was set up to treat leachate from an industrial landfill containing shredder residues of end-of-life vehicles and white goods. The treatment plant consisted of aeration and sedimentation steps for pre-treatment, and a filter. The plant was designed to simultaneously remove various types of pollutants. The efficiencies of pre-treatment and of the main treatment step were investigated
Hydrophobic interaction chromatography (HIC) has been developed as a powerful technique for separating and purifying proteins. In this study, we have characterized the ability of new multimodal pH-HIC media to resolve proteins with only small differences in their primary structures. This was done by determining the retention times of different green fluorescent protein (GFP) mutants prepared from
This paper sets out to create an implementation for fingerprint-based positioning using massive multiple-input multiple-output (MIMO) technology, by means of deep convolutional neural networks (CNN), and utilizing the wireless channel state information (CSI). Due to the sheer volume of computational requirements imposed by CNN processing, an accelerator-assisted design is well-suited to the task a
Ligand exchange on square-planar Pt(1,4-dithiane)2(2+), Pd(1,4-dithiane)2(2+), and Pt(Me2S)4(2+) has been studied as a function of temperature and pressure by H-1 NMR line-broadening, isotopic labeling, and magnetization transfer experiments with deuteriated nitromethane as solvent. Second-order rate constants and activation parameters are as follows: for 1,4-dithiane exchange on Pt(1,4-dithiane)2
Employing a large number of antennas at the base station, massive MIMO significantly improves spectral efficiency and transmit power efficiency. On the other hand, massive MIMO also introduces unprecedented implementation challenges, especially in terms of processing and storage of large-size channel state information (CSI) matrices. Since on-chip memory is generally very expensive and has limited
A Bayesian assessment of the probability that the defendant in a criminal trial is guilty depends on the presumed base rate for guilt and the estimated likelihoods of the evidence. This article explores how the base rate shall be determined. Bayesian scholars have recommended a base rate of 1/N, where N is the number of ‘possible perpetrators’, but it is unclear how the reference class of possible
Sound and radio can be used to estimate the distance between a transmitter and a sender by correlating the emitted and received signal. Alternatively by correlating two received signals it is possible to estimate distance difference. Such methods can be divided into methods that are robust to noise and reverberation, but give limited precision and sub-sample refinements that are sensitive to noise
This chapter aims to be a broad introduction for embedded systems professionals that wish to add machine learning to traditional embedded software. It briefly describes the foundation for a stable and secure IoT communication platform, touching on important areas such as the MQTT protocol and data extraction. The discussion is based on a case study for a digitalized marine vessel, and focuses on g
One of the consequences of Russia’s invasion of Ukraine and the Western sanctions that followed has been deteriorating economic situation in Kaliningrad Oblast. The Russian semi-exclave on the Baltic, already affected by the COVID-19 pandemic and travel restrictions, has suffered from disrupted supply deliveries, closure of externalmarkets and peaking transportation costs.Despite statements made b
This thesis is devoted to the analysis of the I-V properties of axial InP pn-junction nanowires made for solar cell application. A novel method has been used to measure the I-V characteristics very accurately and reproducibly, using scanning tunneling microscopy (STM). The STM is used to first image the nanowires from top and then form a low resistive point contact between the STM tip and an indiv
The outbreak of the Covid-19 pandemic triggered changed circumstances extensively. One aspect of such changes arise from issues in cross-border supply contracts, for example due to incapability of contractual performance because of entry bans and lack of labor force as the employees were set on quarantines. Usually contractual non-performance leads to breacher’s liability for damages, but exceptio
Prehistorical musical instruments have been explored in archaeology more systematically since the 1970s when music archaeology was established as a field of study. The new awareness initially led to studies centred on retrieving musical instruments that had been missed and were now lost in archives. New discoveries, too, are very object-oriented. This master’s thesis ties together individual finds
Moderate exercise is deemed beneficial for cognition due to increase in dopamine concentrations in the basal ganglia. Auditory white noise is beneficial for cognition, mainly for those with lower attentional ability, i.e. for those having lower tonic dopamine concentrations. For individuals with higher attention ability white noise can have a negative effect. In this thesis it was examined whether
This qualitative study applies to young men between the ages of 18 and 21 who live in community homes (HVB hem), and have an ongoing substance abuse and addiction problem. The focus will be on the motivation and treatment that from the young men's perspective promotes the process of change to start a life without addiction. This activity, which fulfills an incredibly essential function in soci
It is described in the preparatory work of the Social Services Act that a reasonable standard of living should be based on the prevailing conditions under which the individual lives. Because there is no specified description of the phrase, this entails interpretability of the phrase and therefore uncertainty about what it infers. The purpose of this study is to analyse the representation of the ph
