III-V MOSFETs for RF Applications

Integration of high-quality oxides on III-V materials allows for versatile design of electronic devices, suitable for RF and power applications. We here present an overview of our results of planar and non-planar III-V MOSFETs for RF electronics, highlighting possibilities and challenges.

VIRTUAL PRESSURE SENSOR BASED ON ION CURRENT MEASUREMENTS USING ARTIFICIAL NEURAL NETWORKS

In-cylinder pressure measurements serve as the gold standard for combustion diagnostics in Internal Combustion Engines. However, the associated costs render it unfeasible to equip engines with in-cylinder pressure sensors. For spark-ignited engines, using the more affordable in-cylinder ion current measurements as an alternative to the traditional pressure sensors has shown promising results for c

Possible effects of new Swedish ventilation regulations for residential buildings

In March 2023, the Swedish national Board of Housing, Building and Planning (Boverket) published a proposal for new ventilation rates in Sweden. The supply air should by this be calculated based on an equation using the heated floor area as the main input. It is set as optional to use less ventilation flow if this could be sufficient. However, in a questionnaire to Swedish practitioners within the

Automatic Control of a Wheelchair Using a Brain Computer Interface and Real-Time Decision-Making

In this study, we simulate the automatic control of an electric wheelchair for indoor Pac-Man-style navigation using solely thought commands. We delve into the decision-making mechanisms of an operational EEG-based brain computer interface that employs a visual oddball paradigm. We investigate strategies to enhance the efficiency of decision-making processes, aiming to accelerate response times wh

Resolving fast Wingbeat Flashes in situ with Entomological Lidar

Specular flashes from insect wings are useful for remote diversity assessment, yet their duration limits and constraining factors remain unknown. We studied this using sampling rates in entomological lidar system up to 40 kHz, resolving quick wing flashes down to 130μs duration from 40 m.

Threshold Saturation for Quantitative Group Testing with Low-Density Parity-Check Codes

We recently proposed a quantitative group testing (GT) scheme with low-complexity peeling decoding based on low-density parity-check (LDPC) codes. Based on finite length simulations and a density evolution analysis we were able to demonstrate that simple (dv,dc)-regular LDPC codes can be more efficient for GT than existing generalized LDPC (GLDPC) code constructions based on BCH component codes. E

Quality Requirements for Code : On the Untapped Potential in Maintainability Specifications

Quality requirements are critical for successful software engineering, with maintainability being a key internal quality. Despite significant attention in software metrics research, maintainability has attracted surprisingly little focus in the Requirements Engineering (RE) community. This position paper proposes a synergistic approach, combining code-oriented research with RE expertise, to create

Core Loss Tracking of Stator Core Testing via Inverse Jiles-Atherton Hysteresis Model

This paper presents a novel optimization strategy for fitting the Jiles-Atherton (JA) hysteresis model to experimental stator yoke core loss measurements and locked-rotor IPMSM calculations. The first study aims to identify a single set of JA model parameters that track sample core losses at different magnetization levels at a given frequency: the analytical model is compared with finite element m

Effects of Temporal Load on Attentional Engagement : Preliminary Outcomes with a Change Detection Task in a VR Setting

Situation awareness in driving involves detection of events and environmental changes. Failure in detection can be attributed to the density of these events in time, amongst other factors. In this research, we explore the effect of temporal proximity, and event duration in a change detection task during driving in VR. We replicate real-world interaction events in the streetscape and systematically

Öppen tillgång vid Lunds universitet 2024

En sammanställning av publiceringsmönster och kostnader Universitetsbiblioteket följer årligen upp andelen öppet tillgängliga vetenskapliga publikationer författade av forskare och doktorander vid Lunds universitet. Syftet är att ge en helhetsbild av hur stor andel av universitetets forskning som publicerats med öppen tillgång, det vill säga fritt tillgängligt online utan prenumerationsbarriärer.
