To optimize precision and accuracy of small dispensed volumes, a dispenser was built. A 96-well plate was loaded with four replicates of a linear pyranine dilution series to test the accuracy and precision of the dispenser machine. Three dilution series of pyranine (100-0 percent, 10-0 percent and 1-0 percent) were made. The results showed that the dispenser has very good accuracy and precision. T
Fog and clouds are difficult to predict for meteorologist today. Models have a tendency to show either too much or too little clouds or fog, which can be a problem for people and industries that depend on the weather conditions. Improvements are being done, but errors still occur. One of the problems is that when an improvement is attained, it might only work for one specific season. This happens,
This study examined compassion for self and for others, and how these factors were related to meaning in life and life satisfaction among university students in Sweden. A total of 265 students from different faculties, most of them at Lund university, responded to a self-report questionnaire including the short form self-compassion scale (SCS-SF), the compassion scale (CS), the multidimensional ex
Objective Image Quality Assessment (IQA) is crucial for evaluating and ensuring the fidelity of images. Traditional human-based evaluations, although reliable, are impractical due to their cost and slow pace, combined with subjective inconsistencies. This thesis aims to address these issues by developing a test and quality bench for Bertin Exensor's dual-head camera, integrating both infrared
This thesis details the development, implementation, and optimization of a local microservice designed to enhance invoice processing at Hulo, a company that manages au- tomatic payment invoices. This is conducted through Artificial Intelligence (AI) and Machine Learning (ML) techniques, focusing particularly on Computer Vision and Object- detection. Motivated by the need to address the inefficienc
To support learning, a sense of trust between student and teacher is required. This assumption is discussed in relation to three human conditions: the biological, the moral and the political. In the oral space of the classroom, teachers and students are dependent on these preconditions when asking: What is a we? What are we doing? What are we making? How emulation and the presence of trust play in
The following text addresses the threats aecting the honey-bee, and which are manifesting through the unusual death rates of bee colonies. Focus is placed in reviewing the scientic knowledge that concerns the honey-bee by discussing its cognitive and ethical categories and its in uence in nature conservation, mainly centred in the EU. Results indicate that scientic knowledge plays a fundamental ro
Feedbacks mechanisms are essential components of our climate system, as they either increase or decrease changes in climate-related quantities in the presence of external forcings. In this work, we provide the first quantitative estimate regarding the terrestrial climate feedback loop connecting the increasing atmospheric carbon dioxide concentration, changes in gross primary production (GPP) asso
During the last several decades, improvements in diagnostic skills and in the treatment of children with cancer have substantially increased the number of long term survivors of childhood cancer. Treatment of children with cytostatic drugs is known to create a range of late adverse effects. Among these are damage to certain structures of the inner ear and hearing impairment. In children, a hearing
Five recent techniques from hybrid and optimal control are evaluated on two power electronics benchmark problems. The benchmarks involve a number of practically interesting operating scenarios for fixed-frequency synchronous dc-dc converters. The specifications are defined such that good performance can only be obtained if the switched and nonlinear nature of the problem is accounted for during th
In this paper three unit root tests that allow for a break in both the seasonal mean and linear trend of the data are proposed. The tests, which can be seen as smallsample corrected versions of already known asymptotic tests, are shown to perform very well in simulations, and much better than their asymptotic counterparts.
A transceiver suitable for devices in wireless body area networks is presented. Stringent requirements are imposed by the high link loss between opposite sides of the body, about 85 dB in the 2.45 GHz ISM band. Despite this, minimum physical size and power consumption are required, and we target a transceiver with 1 mm2 chip area, 1 mW active power consumption, and data rate 250 kbit/s. The receiv
Binding energy shifts between free and solid state atoms for K 2p and Rb 3d photolines have been determined by measuring the vapor and solid state spectra simultaneously in similar experimental conditions applying synchrotron radiation excited photoelectron spectroscopy. This method has the important benefit that the work function is not needed to correct for different reference energy levels, the
Background. The diagnostic work-up and treatment of patients with neuroendocrine neoplasms (NENs) has undergone major recent advances and new methods are currently introduced into the clinic. An update of the WHO classification has resulted in a new nomenclature dividing NENs into neuroendocrine tumours (NETs) including G1 (Ki67 index <= 2%) and G2 (Ki67 index 3-20%) tumours and neuroendocrine car
The problem of integrating the Camassa-Holm equation leads to the scattering and inverse scattering problem for the Sturm-Liouville equation -u '' + 1/4 u = lambda wu, where w is a weight function which may change sign but where the left-hand side gives rise to a positive quadratic form so that one is led to a left-definite spectral problem. In this paper the spectral theory and a generalized Four
In this Letter we analyze the relation between the triple-pomeron and Good-Walker formalism's for diffractive excitation in DIS and hadronic collisions. In both approaches gap events are interpreted as the shadow of absorption into inelastic channels. We here argue that the two formalisms are just different views of the same phenomenon. We first demonstrate how this relation works in a simple toy
Applications of immobilized biocatalysts in both research and industry require highly active catalysts, preferably at a low cost. In this study, cryogels with high catalyst density were produced through cryostructuration of whole Escherichia coli (E.coli) cells. Prepared cryogels are macroporous materials composed of metabolically active cells crosslinked to each other via polymeric structures. Di
This paper presents a new method, based on constraint programming, for modeling and solving scheduling and instruction selection for processors extended with a functionally reconfigurable cell fabric. Our method models parallel reconfigurable architectures, the selection of application specific computational patterns and application scheduling. It takes also into account architectural constraints.
