Recently, IEEE 802.11ax Task Group has adapted OFDMA as a new technique for enabling multi-user transmission. It has been also decided that the scheduling duration should be same for all the users in a multi-user OFDMA so that the transmission of the users should end at the same time. In order to realize that condition, the users with insufficient data should transmit null data (i.e. padding) to f
Modern society is increasingly dependent on IT-systems. Due to this dependence it is importantthat IT-networks are designed to be resilient, meaning that they will either maintain or quickly recover theirfunctionality when exposed to strain. Simulation-based methods that consider supply network topology as wellas system responsible for repairing supply network have previously been used and found t
The role of glial cells in the pathogenesis of many neurodegenerative conditions of the central nervous system (CNS) is now well established (as is discussed in other reviews in this special issue of Frontiers in Neuropharmacology). What is less clear is whether there are changes in these same cells in terms of their behavior and function in response to invasive experimental therapeutic interventi
Why phrases probe FREDRIK HEINAT (L UND UNIVERSITY ) Abstract This paper looks at the arguments for the stipulation that only heads are probes. Three areas where there traditionally have been made a difference between heads and phrases are examined. These areas are, phrase structure, movement, and selection. The strongest argument against probing phrases seems to be selection. Furthermore, Hallman

According to the Swedish higher ordinance of education the development of autonomy of PhD students is of high importance. Graduates should be able to formulate new ideas and to independently assess and evaluate scientific results. Therefore it is interesting to investigate how the relationship between student and supervisor impacts the development of autonomy. In this work, we have evaluated the i

This thesis explores cultural memory and collective identity in trip-hop music. First, I question what it was about Bristol’s history and demography that created such a highly interesting and unusual music scene. To examine how music carries cultural memory, an investigation of significant Bristol artists like Massive Attack and Tricky is undertaken. Expanding the scope, I compare these genres to
In this paper, we introduce a generalized dynamical unbalanced optimal transport framework by incorporating limited control input and mass dissipation, addressing limitations in conventional optimal transport for control applications. We derive a convex dual of the problem using dual optimal control techniques developed before and during the 1990s, transforming the non-convex optimization into a m

An optimal control problem on finite-dimensional positive cones is stated. Under a critical assumption on the cone, the corresponding Bellman equation is satisfied by a linear function, which can be computed by convex optimization. A separate theorem relates the assumption on the cone to the existence of minimal elements in certain subsets of the dual cone. Three special cases are derived as examp
Cybersecurity has in recent years emerged as a paramount concern in the design and operation of industrial systems and civil infrastructures, due mainly to their susceptibility to malicious cyber attacks which take advantage of the vulnerability of communication networks and IT devices. In this paper, we investigate such an attack and counter attack scenario by considering multiagent systems, a so
We envision a future in which multi-antenna technology effectively exploits the spatial domain as a set of non-interfering orthogonal resources, allowing for flexible resource allocation and efficient modulation/demodulation. We may refer to this paradigm as orthogonal space-division multiplexing (OSDM). On the other hand, reconfigurable intelligent surface (RIS) has emerged as a promising technol
It is common for a system integrator to make use of third party intellectual property (IP) blocks from multiple vendors in the design of a circuit. These IPs may include test features, known as instruments, which are connected to a reconfigurable scan network, such as an IEEE Std. 1687 (IJTAG) network, for efficient on-chip integration and communication.Using third party instruments this way becom
Semiconductors use on-chip components, referred to as instruments, for test, debugging, firmware programming, configuration and other important functions. The instruments are needed to ensure proper device operation, however, they may be exploited by an adversary in an attack. With many different actors involved in semiconductor development and manufacturing, it becomes important to restrict acces
