A modified version of the point coordination function (PCF) in the IEEE 802.11 standard called Modified PCF has been introduced as an approach to improve channel utilization over the standard. It has been shown in our previous work that the utilization of the wireless channel can be significantly improved. In this paper, we investigate the performance of the Modified PCF when it is applied with a

The PFS-16 is a 16-item fatigue scale for Parkinson's disease (PD) developed in the UK. However, documented translations and psychometric evaluations are sparse. Aim -  To translate the PFS-16 into Swedish and conduct initial testing of its psychometric properties. Methods -  Following translation, the PFS-16 was administered twice (2 weeks apart) to 30 people with PD (18 men; mean age/PD duration

The language on Swedish rune stones written in the 16 character alphabet (futhark) constitutes a very special fragment of the Swedish of its time (about 800-1100). Because of the ritual character of the inscriptions the language is rather standardized. The greatest variation is in proper names. As has long been noted the typical formula is (in English translation): N raised this stone after M his

During the next three to five years, the municipality of Palanga will make a number of crucial development decisions that will have significant longterm impacts on the lives of its citizens. Because Palanga is a beautiful region whose largely unspoiled natural resources attract many tourists, it is critical that these decisions be made with a view towards environmental sustainability so as not to

Today more and more functionality is included in embedded systems, resulting in an increased system complexity. existing design methodologies and design tools are not adequate to deal with this increase in complexity. To overcome these limitations application specific design solutions are more common. In this thesis we presents such solutions for real-time image processing. This work is part of th

The characterization of exoplanets and their birth protoplanetary disks has enormously advanced in the last decade. Benefitting from that, our global understanding of the planet formation processes has been substantially improved. In this review, we first summarize the cutting-edge states of the exoplanet and disk observations. We further present a comprehensive panoptic view of modern core accret

Aim: To identify responders to continuous glucose monitoring (CGM) in relation to reductions in HbA1c and percentage of time spent in hypoglycaemia after initiation of CGM for individuals with type 1 diabetes treated with multiple daily insulin injections. Materials and Methods: We analysed data from 142 participants in the GOLD randomized clinical trial. We evaluated how many lowered their HbA1c

A push-pull oscillator topology that uses only one type of active device is proposed in this article. A magnetic transformer is leveraged to set positive feedback around a common-collector differential npn transistor pair, implementing the push-pull operation. This results in half the bias current for a given amplitude of oscillation, compared to more standard oscillator topologies. A thorough pha

Microcalorimetry using a 4-channel static ampoule microcalorimeter of thermopile type has been evaluated as a tool for the detection of complement-dependent cytotoxicity against the surface antigens of living cells. Cytotoxic reactions mediated by a rabbit antiserum against human white blood cells and by 2 different monoclonal antibodies recognizing a melanoma-associated antigen on a human melanom

This doctoral thesis consists of four independent research papers. All papers are empirical and cover the area of financial market risk, with a particular focus on systemic risk and volatility in financial markets.The first paper analyzes the joint effect of centrality and other characteristics that are essential in determining banks’ systemic importance. Specifically, centrality is treated as a

Entrepreneurial education as a scientific field can be regarded as an emerging and growing area of research. In this study we pay particular attention to the community of scholars involved in entrepreneurial education. The aim of the paper is to explore how scholars within the field have integrated into larger scholarly communities. Based on a unique database and web-based responses from 313 entre

We describe the macroscopic behaviour of a particle system with long-range interactions. We describe conditions on the interaction strength in dependency of the distance of the particles, such that the scaling limit of the particle system is a well-posed stochastic PDE.

Electrical impedance tomography (EIT) is a noninvasive imaging modality, where imperceptible currents are applied to the skin and the resulting surface voltages are measured. It has the potential to distinguish between ischaemic and haemorrhagic stroke with a portable and inexpensive device. The image reconstruction relies on an accurate forward model of the experimental setup. Because of the rela

A boundary integral equation is described for the prediction of acoustic propagation from a monofrequency coherent line source in a cutting with impedance boundary conditions onto surrounding flat impedance ground. The problem is stated as a boundary value problem for the Helmholtz equation and is subsequently reformulated as a system of boundary integral equations via Green's theorem. It is shown

A Large Intelligent Surface (LIS) is a recently proposed concept, especially suitable for high speed indoor communications and industrial internet of things (IoT) applications. Basing the LIS on smaller panels has clear advantages in terms of flexibility and mass production of its elements. In this paper we consider a panel-based LIS and we study the interplay of the panel size, the number of base

We study a triangular network of three populations of coupled phase oscillators with identical frequencies. The populations interact nonlocally, in the sense that all oscillators are coupled to one another, but more weakly to those in neighboring populations than to those in their own population. This triangular network is the simplest discretization of a continuous ring of oscillators. Yet it dis

The response of a position-sensitive Li-glass scintillator detector being developed for thermal-neutron detection with 6 mm position resolution has been investigated using collimated beams of thermal neutrons. The detector was moved perpendicularly through the neutron beams in 0.5 to 1.0 mm horizontal and vertical steps. Scintillation was detected in an 8 × 8 pixel multi-anode photomultiplier tube
