In this project the concept of digital power was examined. Though not a new phenomena, the concept was new to Micropower. The company develops a wide array of battery chargers and wanted to include this concept in future generations of their products. The reasoning behind the decision is the possibilities of smoother development, better error handling and more communication. As a first step differ
In peritoneal dialysis it is important to make sure the pressure doesn't exceed certain limits. It is desirable to do the measuring without inserting anything inside of the tubing containing the dialysate. This project uses a load cell pressed against the outside of the PVC tubing to estimate the pressure inside. The interval tested is approximately atmospheric pressure +- 220 mBar. The temper
Our interest for this subject was awakened by the complexity with teachers having to report their students for being physically or psychically abused or neglected at home. Our aim in this study has been to discover junior school teachers’ idea on the mandatory reporting law between schools and social services in Sweden. Due to this purpose, interviews have been made with six junior school teachers
Do asylum seekers hold human rights or are human rights bound to citizenship? That is the main underlying question that this essay is trying to answer. The chosen material is an investigation made by the Swedish government about the situation surrounding asylum seekers in Sweden. The analysis consists of the politics around migration, different parts of an asylum seeker’s life and what kind of dev
The purpose was to explore how the staff at women’s shelters handle potential conflicts as part of their overall mandate as well as in their practical day to day work. This qualitative study was based on interviews carried out with staff members at women’s shelters. The people interviewed were chosen for geographical reasons -they were staff members working in shelters in Scania- and partly for re
The electronic structure of methylene peroxide is a balance between zwitterionic and biradical valence structures. In this work we study how this balance is changed by an aqueous solvent, and what effect this has on the nuclear structure. A combined quantum chemical statistical mechanical method with an explicit representation of the solvent is used. The multiconfigurational quantum chemical metho
Basic electrochemistry of glassy carbon paste electrodes (GCPEs) modified with Meldola Blue adsorbed on crystalline a-titanium phosphate (MB-a-TP) electrodes and their ability to catalyze the NADH oxidation have been investigated. Various ratios of glassy carbon (Sigradur K) to MB-alpha-TP, were used to obtain GCPEs. Cyclic voltammetry (CV) and rotating disc electrode (RDE) measurements, performed
The conodont fauna recovered from the Arenig strata of the "Stenbrottet" quarry represents two biozones, i. e. the underlying Baltoniodus triangularis/B. navis Zone and above, the Paroistodus originalis Zone. The thickness of the sediment and the composition of the conodont fauna were compared with those of contemporaneous localities from Öland, Västergötland, Jämtland and Bottenviken. I
The latest version of the Swiss standard for building acoustics (SIA181) introduced a new measurement method, based on a balanced- Arm hammer, for evaluating the decoupling performance of service equipment. This method was developed for reproducing in a standard manner the manipulation of service equipment in bathrooms and kitchens. In this study, we are investigating the relevance of such method
School districts in the US and around the world are increasingly moving away from traditional neighborhood school assignment, in which pupils attend closest schools to their homes. Instead, they allow families to choose from schools within district boundaries. This creates a market with parental demand over publicly-supplied school seats. More frequently than ever, this market for school seats is
A search for the Zγ decay of the Higgs boson, with Z boson decays into pairs of electrons or muons is presented. The analysis uses proton–proton collision data at s = 13 TeV corresponding to an integrated luminosity of 139 fb−1 recorded by the ATLAS detector at the Large Hadron Collider. The observed data are consistent with the expected background with a p-value of 1.3%. An upper limit at 95% con
The n = 0 transition multiplet connecting the lowest quartet states of doubly excited C IV has been studied by beam-foil spectroscopy. The fine structure splittings obtained for the 1s2s2p 4p0and 1s2p2 4p terms confirm previous experimental results with an improved accuracy. The average transition wavelength = (1344.49 0.04)A is now more precisely determined by about a factor of eight. At the new
We present a simple key-recovery attack on the LCMQ Authentication Protocol, an RFID authentication protocol proposed by Li, Gong, and Qin in 2013. We show that a successful attack is performed by solving a Learning Parity with Noise instance in a not-too-large dimension. For the proposed LCMQ parameters, the attack requires only a few invocations with the tag under attack. When there is no restri
We prove the first hardness results against efficient proof search by quantum algorithms. We show that under Learning with Errors (LWE), the standard lattice-based cryptographic assumption, no quantum algorithm can weakly automate TC0-Frege. This extends the line of results of Krajíček and Pudlák (Information and Computation, 1998), Bonet, Pitassi, and Raz (FOCS, 1997), and Bonet, Domingo, Gavaldà
