The widespread deployment of digital technologies has made the globe an interconnected world. Among other necessities of the digitalized world, cybersecurity is a crucial component. Therefore, education and proper training of the cybersecurity workforce are essential for building a strong national and global community. However, a significant shortage of proficient cybersecurity experts is reported
“Han talte de om som en hjälte ”examines the use of parody and satire in the Swedish comedy series S*M*A*S*H (1990) and Pistvakt (1998–2000) as well as the feature film Pistvakt – En albinovästern från de vita vidderna (2005). By analyzing how the series illustrates performative masculinity from the definitions of Judith Butler in Gender Trouble (1990), conclusions on wheth
Millimeter-wave (mmWave) is one key enabler for high data rates in (beyond-)5G wireless communication networks. The use of directive beams and the shorter transmission range in mmWave communications make it easily obstructed or blocked by humans in dynamic real-world scenarios. Connectivity diversity, a solution to link disruption and blockage, could be achieved by deploying distributed multi-poin
Perceiving and understanding human motion is a fundamental problem in computer vision, with diverse applications encompassing sports analytics, healthcare monitoring, entertainment, and intelligent interactive systems. Multi-camera systems, by capturing multiple viewpoints simultaneously, enable robust tracking and reconstruction of human poses in 3D, overcoming limitations of single-view approach
NTRU is a public-key cryptosystem, where the underlying mathematical problem is currently safe against large-scale quantum computer attacks. The system is not as well investigated, as for example RSA, and the company behind NTRU has created the NTRU Challenges, to remedy this. These challenges consist of 27 different public keys of increasing size, where the task in each challenge is to calculate
In post-quantum cryptography (PQC), Learning With Errors (LWE) is one of the dominant underlying mathematical problems. For example, in NIST's PQC standardization process, the Key Encapsulation Mechanism (KEM) protocol chosen for standardization was Kyber, an LWE-based scheme. The primal and the dual attacks are the two main strategies considered for solving the underlying LWE problem of multiple
This enquiry discusses the potential of a large number of linguistic theories, approaches, concepts etc. from Plato to usage-based linguistics for the understanding of the tense system in Ancient Greek, and particularly in the Greek of the New Testament. It is argued that many significant insights within linguistics in the period from the earliest beginning of linguistic thought up to Saussure havThis enquiry discusses the potential of a large number of linguistic theories, approaches, concepts etc. from Plato to usage-based linguistics for the understanding of the tense system in Ancient Greek, and particularly in the Greek of the New Testament.

The last years of turbulence on the market caused by the pandemic and geo-political tensions have led to supply disruptions for many companies. The purpose of this study was to investigate how digital purchasing practices and trust are impacted in the supply chain due to increased turbulence in the environment. This was carried out through an interview study with buyers and sellers in supply chain
Quality requirements complement functional requirements with information on the target quality levels of software functions or emergent system quality aspects. In release planning the allocation of development effort in further investments into product enhancements, new or enhanced functions are competing with quality improvements for limited resources. When setting balanced quality targets for de
A good software architecture is becoming recognized as a major factor for successful products. There has been much research on the technical aspects of software architecture and it is recognized that the driving requirements for architectures are "non-functional", but few have studied how organizations decide on architectural changes. In this paper we study the topic through several case studies.
This paper presents a directional analysis of the on-body propagation channels using the high resolution space alternating generalized expectation (SAGE) maximization algorithm. The analysis has been done on data obtained through FDTD simulations, on a male and a female numerical phantom. For estimating the angle of arrival (AoA) at a four element square array located at the chest, two different p
