A search for production of the superheavy elements with atomic numbers 119 and 120 was performed in the 50Ti+249Bk and 50Ti+249Cf fusion-evaporation reactions, respectively, at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. Over four months of irradiation, the 249Bk target partially decayed into 249Cf, which allowed for a simultaneous search for both elements. Neither was detecte
A search for the fully reconstructed Bs0→ μ+μ−γ decay is performed at the LHCb experiment using proton-proton collisions at s = 13 TeV corresponding to an integrated luminosity of 5.4 fb−1. No significant signal is found and upper limits on the branching fraction in intervals of the dimuon mass are set (Formula presented.) at 95% confidence level. Additionally, upper limits are set on the branchin
Popular Abstract in English From the pure technological perspective (leaving the business aside), the design of electronic devices, such as mobile phones, is an extremely complex process often involving a large number of disciplines, from mastering complicated mathematical models to proficiency of physical and electrical properties of specific materials involved in the manufacturing. In order to oThe methodology behind this work has been to use the concept of algorithm-hardware co-design to achieve efficient solutions related to the digital front-end in mobile receivers. It has been shown that, by looking at algorithms and hardware architectures together, more efficient solutions can be found; i.e., efficient with respect to some design measure. In this thesis the main focus have been plac
People with severe physical disabilities need help with everyday tasks, such as getting dressed, eating, brushing their teeth, scratching themselves, drinking, etc. They also need support to be able to work. They are usually helped by one or more personal
This paper describes a solution to the application of rapid detection of bicycles in low resolution video. In particular, the application addressed is from video recorded in a live environment. The future aim from the results in this paper is to investigate a full year of video data. Hence, processing speed is of great concern. The proposed solution involves the use of an object detector and a sea
A search for second and third generation scalar and vector leptoquarks produced in ep collisions via the lepton flavour violating processes ep -> mu X and ep -> tau X is performed by the H1 experiment at HERA. The full data sample taken at a centre-of-mass energy root s = 319 GeV is used for the analysis, corresponding to an integrated luminosity of 245 pb(-1) of e(+)p and 166 pb(-1) of e(-)p coll
This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. To determine the stellar type, an HR-diagram wa
The NA62 experiment at the CERN SPS reports a study of a sample of 4 × 109 tagged π0 mesons from K+ → π+π0(γ), searching for the decay of the π0 to invisible particles. No signal is observed in excess of the expected background fluctuations. An upper limit of 4.4 × 10−9 is set on the branching ratio at 90% confidence level, improving on previous results by a factor of 60. This result can also be i
Information-theoretic Bayesian optimization techniques have become popular for optimizing expensive-to-evaluate black-box functions due to their non-myopic qualities. Entropy Search and Predictive Entropy Search both consider the entropy over the optimum in the input space, while the recent Max-value Entropy Search considers the entropy over the optimal value in the output space. We propose Joint
Purpose: To search for the tube voltage which results in the highest clinical image quality per effective dose unit for chest and pelvis radiography respectively, using image plates. Methods: Two anthropomorphic phantoms were imaged with several different tube voltages. For the chest phantom, the tube voltage was varied between 70 and 150 kV, and for the pelvis phantom between 50 and 102 kV. The m
Emergency management requires precise and reliable information about the current situation of emergency, existing sources and facilities, while more than 80% of this information has spatial component or location. Considering the urgent and time sensitive nature of emergency situations, it is necessary to collect and use spatial information of the current state of the emergency within the minimum w
This paper describes a novel tool for eliciting user requirements early in the design process of mobile applications. The "Mobile Oracle", as we have called it, is intended to help developers and designers obtain a better understanding of what the user wants at different points in space and time. It is an extension of a lo-fi version of the well-established Wizard of Oz technique, but it adds an "
People who have visual impairments may have difficulties navigating freely and without personal assistance, and some are even afraid to go out alone. Current navigation devices with non-visual feedback are quite expensive, few, and are in general focused on routing and target finding. We have developed a test prototype application for Android in which a user may scan for map information using the
We investigate the difficulty of integrating disparate, heterogeneous systems which have not been designed to work together. Such difficulties may arise from differences in communication protocols or data formats, making an in- tegration effort largely manual and labor intensive. The investigation is done in the context of integrating two different robot systems, one mobile platform running ROS (R
Persons who have survived a stroke might lower the risk of having recurrent strokes by adopting a healthier lifestyle with more exercise. One way to promote exercising is by fitness or exergame apps for mobile phones. Health and fitness apps are used by a significant portion of the consumers, but these apps are not targeted to stroke survivors, who may experience cognitive limitations (like fatigu
This study investigates the interaction problem between a differentialdrive mobile manipulator and one-degree-of-freedom (1-DoF) mechanisms. While previous research has focused on stationary robotic platforms, this work puts emphasis on mobile interaction. Building upon a previously proposed adaptive control strategy for fixed-base manipulators, a holistic control framework is developed to coordin
