Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. The PAs are designed in Cadence AWR design environment with virtual source models, implemented in Verilog-A, of InGaAs nanowire transistors using a 20 nm gate
Architecture greatly influences people‘s lives regarding health, stability, and education and is crucial for economic and social development. This architectural thesis project aims to improve the living conditions of a marginalized community in a rural Tanzanian village, Kisarawe, through a design proposal. It analyzes the potential of humanitarian architecture from the international, European, an
Bakgrund: Oro är ett vanligt inslag under magnetresonanstomografiundersökningar. Det trånga utrymmet kombinerat med det höga ljudet och att behöva ligga stilla är bidragande faktorer till att patienter blir oroliga och kan känna sig klaustrofobiska. Syftet med litteraturstudien var att undersöka hur röntgensjuksköterskan kan lindra vuxna patienters oro i samband med magnetresonanstomografi med hjä
En stor del inom utvecklingen av nya produkter är test och validering. Denna process kräver användning av dyra och stora testsystem. På grund av dessa faktorer är det viktigt att maximera användningen av dessa testsystem. Till följd av detta har ett övervakningssystem utvecklats av test- och validerings-avdelningen på BorgWarner i Landskrona som kan läsa driftstatus (Till exempel på och av) av visA large part of developing products is the testing and validation of the new products. This process requires expensive test systems and a great deal of time and space. Because of these factors it is very important to maximize the usage of the test systems. Therefore, a monitoring system has been developed by the test and validation department at BorgWarner Landskrona that can read the operational
This research investigates the subject of Data Democratization (DD), the effect it has on fact-based decision-making, and how users perceive this within the organization. DD is a fairly new initiative, empowering more employees with increased access to data to improve their use of it and to a greater extent be able to make decisions based on data. The idea for this paper originated from the lack o
Den digitala omställningen har ökat genom åren och har fungerat till en fördel för företag och organisationer generellt. Hastigheten på transformationstillväxten har bibehållits i nutid, vilket har resulterat i att mjukvarusystem utvecklas kontinuerligt. Som en naturlig effekt av detta fenomen, bör aktuella företag alltid ligga i framkant för att förbli konkurrenskraftiga. Studier har visat att pr
Based on the Spain’s annual and quarterly time series from 1980 to 2020, this paper presents the first case study on the dynamic effects of fiscal consolidation episodes on income distribution and the mechanisms driving the specific dynamics of the distribution. By estimating impulse response functions via Local Projections by Jordà (2005), I find supportive evidence of the increase in income ineq
The possibility of being able to examine the inside of the human body is the foundation of today’s medical diagnostics. This can be done through different imaging systems, where ultrasound is one of the most important imaging methods used. Ultrasound does not endanger the patient during examination, unlike other imaging systems that use ionizing radiation or strong magnetic fields. In order to obt
The aim of this empirical study was to find out which characteristics, behaviors, and drives high-performing women have in common in order to illuminate why they have become successful in their work. The aim also included getting insights into some of the challenges that these women meet. Participants were fifteen high-performing women who work in business and academia in Sweden. Semi-structured,
Through the integrated framework of participation theory and political economy, this article analyzes participatory opportunities in the virtual world Habbo Hotel, and how participation is constrained and framed by the producer’s commercial strategies, which are based on advertising and sales of virtual goods. The study also looks into the ways in which the producer Sulake Corporation discursively
Background We evaluated the accuracy and repeatability of a 3D method for polyethylene acetabular cup wear measurements using computed tomography (CT). We propose that the method be used for clinical in vivo assessment of wear in acetabular cups. Material and methods Ultra-high molecular weight polyethylene cups with a titanium mesh molded on the outside were subjected to wear using a hip simulato
The outstanding properties of graphene, a single graphite layer, render it a top candidate for substituting silicon in future electronic devices, The so far exploited synthesis approaches, however, require conditions typically achieved in specialized laboratories and result in graphene sheets whose electronic properties are often altered by interactions with substrate materials. The development of
Quantifying the water exchange between a forest stand and the atmosphere is of major interest for the prediction of future growth conditions and the planning of silvicultural treatments. In the present study, we address (i) the uncertainties of sap flow estimations at the tree level and (ii) the performance of the simulation of stand transpiration. Terrestrial laser scan images (TLS) of a mature b
Purpose – This paper aims to discuss a new tool for requirements gathering in the Web 2.0 era. It seeks to investigate the features that this kind of tool should have in order to be as widely applicable and useful as possible. Further, it aims to explore the extent to which business requirements for enterprise resource planning (ERP) systems can be collected and discussed collaboratively in a worl
OBJECTIVE-Hemoglobin A(1c) (A1C) has emerged as a recommended diagnostic tool for identifying diabetes and subjects at risk for the disease. This recommendation is based on data in adults showing the relationship between A1C with future development of diabetes and microvascular complications. However, studies in the pediatric population are lacking. RESEARCH DESIGN AND METHODS-We studied a multiet
The interactions of the ECM (extracellular matrix) protein asporin with ECM components have previously not been investigated. Here, we show that asporin binds collagen type I. This binding is inhibited by recombinant asporin fragment LRR (leucine-rich repeat) 10-12 and by full-length decorin, but not by biglycan. We demonstrate that the polyaspartate domain binds calcium and regulates hydroxyapati
In order to understand ritual in the past, archaeology has long relied on theories developed in other disciplines. While these theories, which often rely on written or oral information, have added many important dimensions to our interpretation of the archaeological record, they have often proven difficult to successfully articulate with the archaeological sources. Moreover, archaeology has tended
This thesis discusses a rather contentious issue of how copyright law possesses musical works nowadays. It is essentially argued in the thesis that current copyright law appears to be too restrictive, leaving not enough space for creativity in the musical world. In this regard, the issue related to musical works are mainly analysed through the prism of the idea-expression dichotomy. One of the gen
In adaptive deep brain stimulation, a treatment for motor symptoms in Parkinson’s disease, the target of the stimulus is usually in the sub-thalamic nucleus or the globus pallidus. In this thesis, a new stimulus target called reticular thalamus is investigated in a rat model of Parkinson’s disease. The responses to the stimulus were recorded from both local field potentials and action potentials f
