The proper handling of alarms is crucial to automated process control. In practice, many alarms are only distractive and do not represent a fault situation. Here, a toolbox is proposed that aims to reduce the occurrence of the so called nuisance alarms. It is a general computerized tool that takes advantage of the control system's built-in functions, and is a first step to an enhanced overall alar
Present power system will face great challenges in several areas depending on the market economy, extensive global integration and constant need for more electric power, which will force the system to operate much closer to its stability limits. Meeting these challenges may involve improving and complementing or even total restructuring of the power systems.New technologies are emerging such as re
This paper focuses on the use of Life Cycle Assessment (LCA) to evaluate the performance of seventeen control strategies in wastewater treatment plants (WWTPs). It tackles the importance of using site-specific factors for nutrient enrichment when decision-makers have to select best operating strategies. Therefore, the LCA evaluation is repeated for three different scenarios depending on the limita
Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. ammonium, nitrate and phosphate. The thesis is about rea
Facial beat gestures align with pitch accents in speech, functioning as visual prominence markers. However, it is not yet well understood whether and how gestures and pitch accents might be combined to create different types of multimodal prominence, and how specifically visual prominence cues are used in spoken communication. In this study, we explore the use and possible interaction of eyebrow (
The paper aims to identify and analyse potential legal avenues for phasing out fossil fuel subsidies (FFS) in the European Union (EU) using State aid rules. Our analysis reveals that the EU State aid rules would allow the European Commission to effectively target and monitor a vast number of FFS. From a policy perspective, the requirements for notification, examination, transparency, reporting, an
Turbulent breakup in emulsification devices is a dynamic process. Small viscous drops undergo a sequence of oscillations before entering the monotonic deformation phase leading to breakup. The turbulence-interface interactions prior to reaching critical deformation are therefore essential for understanding and modeling breakup. This contribution uses numerical experiments to characterize the criti
PURPOSE: Psychological readiness may play an important role in the return to sport (RTS) process following hip arthroscopy (HA), but there are limited tools for the measurement of this construct. The aim of this study was to modify the Swedish version of the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale for use in HA patients and evaluate its psychometric properties.METHO
In everyday conversations, we frequently give an example. Yet this is seldom accompanied by any reflection on what is going on when we do so. This report tries to contribute such a reflection. It shows how examples may be marked and used in a particular discourse: oral discourse on others. The empirical material is a transcribed focus group interview with a group of Swedish students, engaged in di
Clothing evaporative resistance is one of the most important inputs for both the modelling and for standards dealing with thermal comfort and heat stress. It might be determined on guarded hotplates, on sweating manikins or even on human subjects. Previous studies have demonstrated that the thermal manikin is the most ideal instrument for testing clothing evaporative resistance. However, the repea
Glazed spaces ranging from small glazed verandas to large atrium buildings have become a common feature in architecture. A glazed space is greatly affected by aspects of the outside climate such as insolation and temperature. In the design of such spaces, more sophisticated design tools are therefore required in order to estimate the climate inside the glazed space and the energy requirements for
Constraining the climate impact of particulate brown carbon (BrC) will require identification of formation mechanisms and isolation of its different components to allow for source apportionment. For fresh combustion aerosols, the light absorption characteristics and the Absorption Ångstrom Exponent (AAE) are principally controlled by the combustion conditions in which the particles formed and evol
As the construction industry adopts more data-driven and sustainable practices, Building Information Modelling (BIM) is increasingly used for energy analysis, lifecycle management, and maintenance planning. However, its integration with service life performance analysis especially for wood, a material susceptible to environmental degradation remains limited. This study presents a BIM-based framewo
This study explores sustainable energy renovation strategies for a congregation building in southern Sweden using a parametric optimization approach to balance passive and active measures. Passive measures include envelope and window improvements and leakage control, while active measures involve photovoltaic integration and ventilation enhancements. The renovation aims to optimize energy use, the
