This letter proposes a co-designed millimeter-wave (mm-wave) and sub-6GHz antenna system. The antenna system consists of four 28GHz mm-wave arrays with reconfigurable radiation patterns and two sub-6GHz antennas fed with two corner capacitive coupling elements (CCEs). Each corner CCE is formed by the connected ground planes of two mm-wave arrays in the shared-aperture configuration. The two CCEs a
This study aimed to disentangle the influence of information status and referential form on the distribution of gestures in sustained discourse. Previous research shows that new/less accessible rather than old/more accessible information, expressed by rich rather than lean referential forms, is more likely to be accompanied by gestures. However, earlier studies have drawn on correlational results.
This paper shows how a channel sounder can be built with National Instruments (NI) Universal Software Radio Peripheral (USRP) equipment, featuring onboard FPGA processing and utilizing open-source tools. Compared to other USPR-based channel sounders, our design eases the requirements on the data link between the USRP and the host, limits the measurement data size, and increases the signal-to-noise
This thesis studies two families of methods for finding zeros of finite sums of monotone operators, the first being variance-reduced stochastic gradient (VRSG) methods. This is a large family of algorithms that use random sampling to improve the convergence rate compared to more traditional approaches. We examine the optimal sampling distributions and their interaction with the epoch length. Speci
Cloud computing has quickly grown to become an essential component in many modern-day software applications. It allows consumers, such as a provider of some web service, to quickly and on demand obtain the necessary computational resources to run their applications. It is desirable for these service providers to keep the running cost of their cloud application low while adhering to various perform
Computational methods to understand interactions in bio-complex systems are however limited to time-scales typically much shorter than in Nature. For example, on the nanoscale level, interactions between nanoparticles (NPs)/molecules/peptides and membranes are central in complex biomolecular processes such as membrane-coated NPs or cellular uptake. This can be remedied by the application of e.g. J
The contributions from anions and cations from salt are inseparable in their perturbation of molecular systems by experimental and computational methods, rendering it difficult to dissect the effects exerted by the anions and cations individually. Here we investigate the solvation of a small molecule, caffeine, and its perturbation by monovalent salts from various parts of the Hofmeister series. U
In this paper, characteristic mode analysis is used to gain insight into the operation of millimeter-wave series patch array. It is shown that the series patch array (broadside) mode has lower modal bandwidth and higher resonant frequency than the corresponding mode of a constituting patch element, whereas the other dominant orthogonal (broadside) mode is identical between the array and the single

As the world is changing rapidly in many ways, competition is getting increasingly fierce amongst manufacturing firms. As such, it has become more and more important for companies to properly understand the needs of their customers in order to provide enough value to be sufficiently competitive. Providing delivery and installation services which might’ve been viewed as necessary evils before have
Idag är kommunikation, marknadsföring och transaktion av produkter nyckelfunktioner för produktförpackningar. Kvaliteten på det grafiska förpackningstrycket är därför av stor betydelse och måste vara konsekvent för stora produktionskvantiteter. En av de vanligaste tryckteknikerna för tryck på papper eller kartong är flexografiskt tryck. Med denna teknik appliceras färger en efter en och genom deraToday communication, promotion and transaction of products are key functions of product packaging. The quality of the package print is therefore of great importance and needs to be consistent for large production quantities. One of the most common technologies for printing on paper or cardboard is flexographic printing. With this technology colors are applied one by one and through their combinati
Significant behavioral changes will need to be implemented to prevent the energy supply sector from tripling CO2 emissions by the midcentury. However, within the academic research, behavior changes remain primarily focused on the individual level, while the behavior of companies that are responsible for elevated greenhouse gas emissions falls behind. This master’s thesis analyses the core values
Syfte: Syftet med förändringsarbetet är att hjälpa Varberger Sweden AB att skapa den fungerande produktionsapparat som behövs för att jobba enligt den av företaget utarbetade affärsidén med kärnkompetens och kundanpassning. Arbetet kommer att beskriva det använda arbetssättet, dvs. analysarbetet, men huvudsyftet är att skapa förändringar i företaget och så långt som möjligt implementera dessa. PrPurpose: The purpose with the work of change was to help the company Varberger Sweden AB to change its way of working and by that enabling the company to reach the developed business concept were core competences such as precision and customization was seen as the key to success. Task description: The company Varberger Sweden AB have for different reasons gone into bankruptcy some times during th
Ledarskap har länge varit populärt inom managementforskningen och utvecklingen av ledarskapsfältet går mot att studera fenomenet genom vardagliga ansatser och på ett mer praktikorienterat sätt. Forskningen fortsätter dock längs med denna utveckling att studera ledarskap på ett fragmenterat sätt och därmed se det som något entydigt. I motsats till detta har syftet med denna uppsats istället varit a
The purpose of this thesis is to investigate how the autonomy in an acquired subsidiary affects the integration process within an M&A process. The study uses a qualitative and deductive method by conducting a case study in a major Swedish technological company. We have made five different hypotheses based on three prominent articles within the M&A research area that deal with the subject o

The study has a qualitative approach and is based on the perspective of the intelligence analyst, with focus on relevance to the analytical process. The theo
This bachelor thesis builds on an uneven diabetic health care, more specific at Swedish medical clinics where patients with type-1 diabetes are being treated. Today patients are not able to get the same benefits, the access and quality of health care is based on where patients are getting their treatment. However, this is not compatible with the Swedish law saying that the purpose of health care i
This thesis aims to explore whether an artistic creative type model can be applicable in an entrepreneurial setting. Meta Wagner’s model was selected as the artistic creative type model in this study. Conducting qualitative research through a case study approach on startup founders, who share a common background in entrepreneurial education, allows us to deepen our understanding of the founder
