Simulation nimmt eine wesentliche Rolle im Engineering und Betrieb von Maschinen und Anlagen ein. Der manuelle Aufwand, der mit der Modellierung, Simulation sowie der Wartung und Pflege der Modelle einhergeht, ist jedoch nach wie vor über alle Lebenszyklusphasen hinweg erheblich. So müssen Modelle aus unterschiedlichen Disziplinen, wie beispielsweise der Mechanik, der Thermodynamik oder der Elektrik, zu einem Gesamtmodell gekoppelt werden. Kommt es im weiteren Verlauf zu umbaubedingten Änderungen der Anlage, muss das Modell wiederum einem Update unterzogen werden, was erneuten Aufwand bedeutet. In diesem Beitrag erweitern die Autoren ihr bereits vorgestelltes Konzept eines Assistenzsystems zur automatischen Konfiguration und betriebsparallelen Adaption von Co-Simulationen. Ziel ist es, dass produktionsbedingte Umbaumaßnahmen an der realen Anlage automatisch festgestellt, in die Co-Simulation überführt und in einem bestehenden Beschreibungsmittel der Anlage dokumentiert werden. Das erweiterte Konzept wird anhand von zwei industriellen Anwendungsbeispielen aus unterschiedlichen Bereichen der Fertigungstechnik prototypisch validiert.

A sustainable student housing project in Varvsstaden, Malmö, Sweden, that promotes a circular way of living. By upcycling materials from the former shipyard, the project creates new housing, public spaces and utilizing existing resources. Efficient use of built surfaces, support for community needs, and accessible housing options are key aspects of Varvet. The project also aims to contribute to cultural sustainability by encouraging social interactions among residents. Varvet recognizes the importance of community living as an affordable and accessible option for promoting sustainability. By sharing resources, and facilitating new social interactions, co-living can contribute to a safer and more culturally sustainable society. The project offers not only a home for 90 students but also diverse experiences and activities, such as purchasing locally grown food, sport activities and enjoying live music. Sustainable development requires considering both environmental and social aspects. Varvet - Circular Co-Living embodies this approach, advocating for more sustainable living practices that prioritize the needs of both present and future generations.

Hepatitis is an infectious disease that affects millions of people worldwide. The current project seeks to achieve two objectives: 1) To understand how hepatitis policies affect hepatitis prevalence in prison, and 2) To understand how hepatitis prevalence in prison affects the general population. Using a content analysis of correctional policies available through each state Department of Corrections (DOC) and secondary data from the 2010 Census, Centers for Disease Control and Prevention, and Corrections Compendium; hepatitis prevalence and policies are analyzed. The content analysis employed for this study revealed that some states have more comprehensive policies than others. However, all states may benefit from modifying their policies to meet recommendations constructed by the Federal Bureau of Prisons. Findings from descriptive statistics also suggest changes in HIV prevalence and policies positively affect hepatitis C prevalence. Future research should be dedicated to examining how personal interactions in prison also affect prevalence rates.

Peer reviewed journal articles are one way in which scholars communicate with each other and the public. Such publications create networks of collaboration. This study uses social network analysis techniques and theory to examine the network of collaborations that occur in public administration. Social network analysis is a perspective that takes into account the structure of relationships that can exist among individuals, organizations or other entities (Wellman, 2008). The small world theory is the specific theoretical framework that guides this study. The small world theory is based on the notion that despite a population being very large, individuals in that population are still connected with each other within a few steps. The author constructs a scientific network of research collaborations by assigning a relationship to two actors who have co-published an article together in the Public Administration Review, American Review of Public Administration, or The Review of Public Personnel Administration during the time periods of January 2003- December 2011. The results of this analysis reveal that the public administration network consists primarily of faculty members. The network also exhibits a high degree of clustering and several cliques. On average, individuals in the network are only slightly farther apart from each other than what would be expected in a small world network. This research contributes to public administration by introducing scientific networks of collaboration to public administration. The field has not ignored who publishes in its journals, but it has not used network analysis techniques to examine such publications. This study demonstrates how network analysis techniques and methodology can be used to examine a large network. Finally, this research contributes to the small world theory by applying it to scientific networks in public administration.

Ammonia and hydrogen are two alternative fuels that can help decarbonization as they can be produced using renewable energy. Ammonia has transportation, handling, and storage advantages over hydrogen even though its combustion characteristics are worse. One intermediate strategy to use ammonia or hydrogen as a fuel is to co-fire it with hydrocarbons. However, co-firing with hydrocarbons may emit harmful pollutants such as NOx and soot. This study investigates the effects of ammonia and hydrogen addition on soot formation in laminar coflow nitrogen-diluted-ethylene normal diffusion flames using experimental techniques. Ammonia and hydrogen were added separately to the fuel flow. Flame conditions from 0 to 50 vol% of the added species (ammonia or hydrogen) were tested. Laser diagnostics for measuring the distributions of polycyclic aromatic hydrocarbons (PAHs) and soot volume fraction (SVF), and intrusive measurements (using a thermocouple and probe sampling) were performed. Based on the results, ammonia addition suppressed soot formation while hydrogen addition enhanced it. In conditions with ammonia addition, the temperature measurements with a Type S thermocouple and adiabatic flame temperature simulations using CHEMKIN PRO showed similar temperature profiles and negligible adiabatic flame temperature differences respectively. The qualitative PAH measurements using planar laser induced fluorescence (PLIF) showed that the concentration of PAHs of four or larger rings reduced with ammonia addition. Soot volume fraction (SVF) measurements using planar laser induced incandescence (PLII) showed that the peak SVF decreased exponentially with ammonia addition. Particle size distributions showed that the incipient particles were formed, however growth to mature primary particles was limited with 25% or higher ammonia addition in the flame. Based on similar temperature profiles and decreasing trends in the distribution of PAHs and SVF, soot suppression with ammonia addition was linked to chemical effects. PLIF measurements with hydrogen addition could be affected by the temperature difference between the flames, therefore further investigation is needed. PLII measurements, however, showed that the soot volume fraction increased linearly with hydrogen addition.

Sjukvården ska vara jämlik för alla patienter, men rapport från Socialstyrelsen visar att det finns brister i den svenska sjukvården. Ögonsjukvården på ett av Sveriges större sjukhus fick under sommaren 2021 in synpunkter gällande bristande tillgänglighet och bemötande. Ögonsjukvården hade lokaler som inte var anpassade för patienter med synskada, och bemötandet visade brist på insikt i hur det är att ha en synskada. Ett projekt startades i samarbete med Synskadades Riksförbund, för att tillsammans åtgärda dessa brister. Fyra patienter med synskada fick besöka ögonmottagningen och uppmärksamma brister och ta fram åtgärdsförslag. De fick även svara på en enkät före och efter genomförandet av åtgärderna för att senare kunna utvärdera om förändringarna lett till en förbättring eller inte. Frågorna gällde fyra aspekter i tillgänglighet på olika delar av sjukhuset. För att förbättra bemötandet föreslog Synskadades Riksförbund en insiktsutbildning för personalen. Utbildningen skulle ledas av personer med synskada, med målet att öka personalens förståelse för hur det är att leva med en synskada, Utbildningen följdes av en intervjustudie för att undersöka medarbetarnas erfarenhet av co-production, och hur verksamheten i framtiden kan samarbeta med patienterna. Resultatet visar att alla utom en patient upplevde förbättring av tillgängligheten på alla fyra aspekter. En av patienterna tyckte att tre av fyra aspekter hade förbättrats. Totalt 23 medarbetare hann genomgå insiktsutbildningen. Målet på en ökad tillgänglighet uppnåddes, medan målet om att hinna med att utbilda 30 medarbetare inte uppnåddes. Resultatet av studien visade att co-production är ett uppskattat arbetssätt som anses effektivt för att uppnå mer jämlik sjukvård. Slutsatsen är att co-production tillsammans med patienterna har lett till både bättre tillgänglighet och bättre bemötande. Projektet fortsätter, och målet under året är att alla medarbetare ska hunnit genomgå insiktsutbildningen. Projektet har tilldelats medel för fortsatta insatser för en mer jämlik sjukvård för ögonsjukvårdens patienter. / Healthcare must be equal for all patients, but a National Board of Health and Welfare report found shortcomings in Swedish healthcare in this area.  During 2021 the eyecare department at one of Sweden’s largest hospitals received remarks on accessibility and service. The facilities were not adapted for visually impaired patients, and they felt a lack of insight into their needs. A joint project was started with the Swedish Association of Visually Impaired (SRF) to address these shortcomings. Four members with visual impairments visited the clinic to assess the facilities, in order to propose an improvement plan. The participants also completed a questionnaire, before and after implementation of changes, to evaluate if it had improved. The questions covered four aspects of accessibility in different parts of the hospital. To improve the patient interaction, SRF proposed awareness training for hospital staff. The training was led by visually impaired people, with the goal of increasing awareness about living with visual impairments. The training was followed by a study about the staffs’ experience on co-production and how future collaboration with patients could be done. The results show that all but one patient experienced an improvement in accessibility in all four aspects. One of the patients thought that three out of four aspects had improved. 23 employees completed the awareness training. The goal of increased accessibility was achieved; however, the goal of training 30 employees was not reached. The study showed that co-production is appreciated and was considered effective in achieving more equal healthcare.  The conclusion is that co-production led to both better accessibility and treatment. The project continues, and the goal is for all employees to complete awareness training this year. The project has secured funds for continued efforts for a more equal healthcare for eye care patients.
