Circularly polarized sub-THz antenna design for distributed deployment

Sub-THz deployment is challenging due to high propagation losses, necessitating dense deployment. To reduce cost, RF signal can be distributed via plastic fiber to remote radio units to increase coverage area. In this paper, we propose an antenna-in-package concept for the single-layer substrate on low-cost embedded wafer level ball grid array (eWLB) packages. To suppress the distortion in the bro

Cooperation for Ethical Autonomous Driving

The success in the adoption of autonomous vehicles is dependent on their ability to solve rarely occurring safety-critical corner cases. Vehicular communications (V2X) aim at improving safety and efficiency of autonomous driving by adding the capability of explicit inter-vehicular information exchange. We argue that V2X enables another important function, namely the support of ethical driving deci

Modified almost unbiased two-parameter estimator for the Poisson regression model with an application to accident data

Due to the large amount of accidents negatively affecting the wellbeing of the survivors and their families, a substantial amount of research is conducted to determine the causes of road accidents. This type of data come in the form of non-negative integers and may be modelled using the Poisson regression model. Unfortunately, the commonly used maximum likelihood estimator is unstable when the exp

Economic Inequality in the Nordics in Times of Neoliberalism

This chapter explores the interrelationship between neoliberalism and economic inequality through a comparison of Denmark, Finland, Norway and Sweden, using Sweden as a main case and the other three major Nordic countries as comparative cases. The argument is that the relationship between neoliberalism and inequality isn’t a one-way street, but rather a question of mutual determination.

A new Poisson Liu Regression Estimator : method and application

This paper considers the estimation of parameters for the Poisson regression model in the presence of high, but imperfect multicollinearity. To mitigate this problem, we suggest using the Poisson Liu Regression Estimator (PLRE) and propose some new approaches to estimate this shrinkage parameter. The small sample statistical properties of these estimators are systematically scrutinized using Monte

Global Knowledge Rituals : United Nations Day and the Global Fifties

AbstractThis study investigates the establishment and significance of United Nations (UN) Day, October 24, in Swedish primary and secondary schools from 1948 to 1963. This article conceptualizes the celebrations as knowledge rituals, educative events that foreground practices of knowledge-sharing, reinforcing social bonds and enhancing collective understanding. UN Day knowledge rituals combined ce

On some beta ridge regression estimators : method, simulation and application

The classic statistical method for modelling the rates and proportions is the beta regression model (BRM). The standard maximum likelihood estimator (MLE) is used to estimate the coefficients of the BRM. However, this MLE is very sensitive when the regressors are linearly correlated. Therefore, this study introduces a new beta ridge regression (BRR) estimator as a remedy to the problem of instabil

Förutbestämda liv och utbildningens syfte : En litteratursociologisk läsning av Kazuo Ishiguros roman Never Let Me Go

Den här studien tar sin utgångspunkt i Kazuo Ishiguros dystopiska roman Never Let Me Go. Med teoretiskt stöd från Gert Biestas (2011) tre utbildningsdimensioner – kvalificering, socialisering och subjektifiering – samt barndomssociologins dikotomi being och becoming (Jenks 1982; James, Jenks & Prout 1998), analyseras hur romanen förhåller sig till och problematiserar relationen mellan barndom,

Low-frequency noise in ferroelectric III-V vertical gate-all-around FETs

In this letter, we demonstrate low-frequency noise (LFN) characterization of an InAs vertical gate-all-around hafnium-zirconium oxide (HZO) ferroelectric field-effect transistor (FeFET). The LFN characteristics are investigated before and after ferroelectric switching for up to 1000 cycles in the FeFET. The evolution of such cycling reveals distinct differences in the LFN for the two polarization

Evaluation of Total Column Ozone derived from CAMS against AIRS datasets across the Indian subcontinent

Present work examined the spatio-temporal variability of total column ozone (TCO) using the Copernicus Atmospheric Monitoring Service (CAMS) reanalysis dataset (2005–2020) over the Indian subcontinent. TCO data from CAMS is evaluated against the TCO from the Atmospheric Infrared Sounder (AIRS) satellite dataset using descriptive statistical analysis. CAMS TCO shows better agreement with AIRS TCO w

Wigner-function formalism for the detection of single microwave pulses in a resonator-coupled double quantum dot

Semiconductor double quantum dots (DQD) coupled to superconducting microwave resonators offer a promising platform for the detection of single microwave photons. In previous works, the photodetection was studied for a monochromatic source of microwave photons. Here, we theoretically analyze the photodetection of single microwave pulses. The photodetection in this case can be seen as a nonlinear fi

Impact of antenna pattern directivity on near-field focusing of planar array in large intelligent surface applications

Near-field focusing (NFF) is a fundamental enabler for a broad spectrum of applications utilizing large intelligent surfaces (LIS) within sub-10 GHz frequency bands. This paper investigates the impact of element pattern on NFF properties, when the LIS array is a large planar array. The NFF properties of maximum received power, focal width, and focal depth are analyzed for three typical antenna pat

The Sacred Battlefields of the Eastern Europe : The Role of Orthodox Christianity in Geopolitics

Special Issue InformationIs Orthodox Christianity primarily a tool or resource used by political entities, or does it act as an independent social force with the power to drive political outcomes? How does this religion, as a transnational force, shape global politics? The special issue "Sacred Battlefields: The Role of Orthodox Christianity in Geopolitics" seeks to address these overarching quest

Characterization of emerging non-volatile cryogenic memories

In this thesis, two emerging non-volatile memories, being the resistive random access memory and a ferroelectric capacitor were characterized at cryogenic temperatures. This was carried out due to the demand for non-volatile CMOS compatible cryogenic memories for quantum computing applications. Both devices exhibit good switching characteristics, endurance >10^7 cycles and multilevel capability. M
