Massive MIMO Channel Modeling - Extension of the COST 2100 Model

As massive MIMO is currently considered a leading 5G technology candidate, channel models that capture important massive MIMO channel characteristics are urgently needed. In this paper we present an attempt for massive MIMO channel modeling based on measurement campaigns at 2.6 GHz in both outdoor and indoor environments, using physically-large arrays and with closely-spaced users. The COST 2100 M

The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography

Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. The studies in this work invol

An Inquiry into Cultural Semiotics: Germaine de Staël's Autobiographical Travel Accounts

Popular Abstract in Swedish Kultursemiotiken studerar möten mellan kulturer. Begreppen Kultur, Extra-kultur och Icke-kultur utvecklades av Tartuskolan under 1970-talet, och användes i deras studier av den ryska kulturen och dess relation till Västeuropa. Särskild vikt lades vid Peter den Stores försök att göra Ryssland mer likt Väst. Målet med denna avhandling i kultursemiotik är att vidareutvecklCultural semiotics studies encounters between cultures. Notions such as Culture, Extra-culture and Non-culture were developed in the 1970s by the Tartu school and were used in their studies of Russian culture and its relation to Western Europe, with special focus on Peter the Great's attempt to Westernize Russia in the eighteenth century. The aim of this dissertation in cultural semiotics is to fu

Marknaden för populuxetryck efter sekelskiftet 1800

Around 1800 and thereafter there was a rising consumption of books and other print material in Sweden. Almanacs, handbooks and fiction, especially for women, children’s books, ABC- and conversation cards and other prints such as, games, pictures for cutting and music was advertised in newspapers and booksellers catalogues. In this text the production and commercialisation of these products is look

A dynamic model of an atmospheric solid oxide fuel cell system for stationary power generation

This paper focuses on the transient behavior of a solid oxide fuel cell system used for stationary power production. Dynamic modelling is applied to identify the characteristic time scales of the system components when introducing a disturbance in operational parameters of the system. The information on the response of the system may be used to specify the control loops needed to manage the change
