The recent interest in massive MIMO has spurred intensive work on massive MIMO channel modeling in contemporary literature. However, current models fail to take the characteristics of terminal antennas into account. There is no massive MIMO channel model available that can be used for evaluation of the influence of different antenna characteristics at the terminal side. In this paper, we provide a
The first measured results for massive multiple input, multiple-output (MIMO) performance in a line-of-sight (LOS) scenario with moderate mobility are presented, with 8 users served in real-time using a 100 antenna base Station (BS) at 3.7 GHz. When such a large number of channels dynamically change, the inherent propagation and processing delay has a critical relationship with the rate of change,
Using the metrics of channel capacity and multiplexing efficiency, the adaptive impedance matching (AIM) performances of two multiple-input multiple-output (MIMO) terminals with different antenna designs were evaluated and compared. The evaluation was performed in LTE Band 18 Downlink (860-875 MHz) under realistic usage conditions of two measured user handgrips and simulated propagation channels w
Standing on a foam surface is believed to exaggerate balance deficits by decreasing the reliability of somatosensory information from cutaneous mechanoreceptors on the plantar soles (i.e. base of feet) and by altering the effectiveness of ankle torque. The aim was to further document the nature of foam posturography testing by comparing between standing on foam and standing with decreased Rapidly

Det är statens suveräna rätt att reglera utlänningars närvaro inom dess territorium. Denna rätt är däremot inte utan begränsningar. Artikel 1 i protokoll nr. 7 till Europeiska konventionen om skydd för de mänskliga rättigheterna säkerställer rättssäkerhetsgarantier i samband med utvisningen av utlänningar. Dessa rättssäkerhetsgarantier måste tillgodoses vid utvisningsförfarandet i de medlemsstaterIt is the sovereign prerogative of the state to regulate the presence of aliens within its territory. This right, however, is not without limits. Article 1 of Protocol No. 7 to the European Convention on Human Rights ensures procedural safeguards relating to the expulsion of aliens. These safeguards must be considered in expulsion proceedings by those Member States having ratified the protocol.
Den nya mediemiljön med sociala medier gör det möjligt att konstruera och styra mediebilden av sig själv, men ett ständigt informationsflöde bidrar till en kamp om uppmärksamheten. Det finns flertalet exempel på personer som ständigt figurerar i medierna och som spelar spelet om respekt i offentligheten, men vissa frotterar sig i finrummen medan andra inte gör det. Hur kommer detta sig? Studiens m
With the increase of devices connected to 5G services, the importance of tuning User Equipment (UE) to their assigned frequency slot becomes increasingly vital. This paper approached this issue by securing the control signals sent through a Serial Peripheral Interface (SPI) in digital beamforming radios. This was done by securing three distinct components: the transmitting end of the channel, the
As a prominent category of side-channel attacks (SCAs), plaintext-checking (PC) oracle-based SCAs offer the advantages of generality and operational simplicity on a targeted device. At TCHES 2023, Rajendran et al. and Tanaka et al. independently proposed the multiple-valued (MV) PC oracle, significantly reducing the required number of queries (a.k.a., traces) in the PC oracle. However, in practice
Climate models have continued to be developed and improved since the AR4, and many models have been extended into Earth System models by including the representation of biogeochemical cycles important to climate change These models allow for policy-relevant calculations such as the carbon dioxide (CO2) emissions compatible with a specified climate stabilization target. In addition, the range of cl
The Hamming Quasi-Cyclic (HQC) key encapsulation mechanism (KEM), recently selected by NIST for standardization in the Post-Quantum Cryptography (PQC) process, distinguishes itself through its efficiency, robust design based on hard decoding problems in coding theory, and well-characterized decryption failure rates. Despite its selection, practical security concerns arise from implementation threa
We study a network formation game where n players, identified with the nodes of a directed graph to be formed, choose where to wire their outgoing links in order to maximize their PageRank centrality. Specifically, the action of every player i consists in the wiring of a predetermined number di of directed out-links, and her utility is her own PageRank centrality in the network resulting from the
In this paper, we propose a scheme to identify discrete-time, multi-input/multi-output switched-linear systems (MIMO-SLSs) from input-output measurements. The key step is an observer-based transformation to a switched auto-regressive with exogenous input (SARX) model. This transformation converts the state-space (SS) identification problem into a MIMO-SARX identification problem by compressing inf
Artificial intelligence (AI) and machine learning (ML) are rapidly permeating nearly every aspect of modern life, frompersonal devices and autonomous systems to industrial automation and environmental monitoring. The growing demandfor intelligence at the network edge is reshaping how computing hardware is conceived and built. Edge AI platforms areexpected to deliver high throughput within tight en
Förevarande uppsats syftar till att utreda vilka drivkrafter som föregick och motiverade rättsutvecklingen inom prostitutionslagstiftningen mellan åren 1850 och 1999. Därtill redogör uppsatsen för hur statsmaktens inställning gentemot prostitution och prostituerade kvinnor tog sig uttryck i den legisla-tiva utvecklingsprocessen. Arbetet har genomförts med hjälp av en rättshisto-risk metod för att This paper aims to investigate the driving forces that preceded and motivated the developments of the law in legislation concerning prostitution between the years of 1850 and 1999 in Sweden. Further more, the paper describes how the state's attitude towards prostitution and prostituted women was expressed in the legislative development process. The work has been undertaken using a legal-histor
Bildstyrd strålterapi är en process bestående av att ta 2D eller 3D bilder under strålbehandlingens gång och används för att försäkra sig om att patienten är positionerad på samma sätt som referensbilden för att få samma dos som planerades (beräknat på referens bilden). I det här arbetet har en 3D scanning av patientens positionering jämförs med en CT referensbild för patienten.
