In der vorliegenden Diplomarbeit wird die akustische Wahrnehmbarkeit von Kleinkollisionen im Niedriggeschwindigkeitsbereich untersucht. Ziel war es, ein methodisches Vorgehen zu entwickeln, mit dem sich die Entstehung und Wahrnehmung solcher Kollisionsgeräusche erfassen und bewerten lassen. Dazu wurden Streifkollisionen unter definierten Bedingungen im Akustikraum der Westsächsischen Hochschule Zwickau aufgezeichnet und messtechnisch sowie akustisch analysiert. Ergänzend erfolgte ein Probandenversuch zur Untersuchung der Wahrnehmung unter verschiedenen Maskierungsbedingungen. Die Ergebnisse zeigen, dass die Wahrnehmbarkeit nicht allein vom Schalldruckpegel abhängt, sondern auch von der spektralen Zusammensetzung und dem zeitlichen Verlauf der Geräusche beeinflusst wird. Die Arbeit liefert einen Ansatz für die Bewertung der akustischen Wahrnehmbarkeit von Kleinkollisionen und kann als Grundlage für weiterführende Untersuchungen im Bereich der Unfallanalytik dienen.
The automotive industry is currently facing significant uncertainties and challenges. At the same time, efforts to achieve emission-free mobility are leading to power train diversity. In this complex environment, it is essential for car producers to define an efficient and resilient production strategy of future car production networks. This article provides a universal approach and simulation model to evaluate production strategies considering power train diversity. A case study, mirroring possible scenarios for automotive manufacturers, shows that a certain proportion of mix production can have an advantage in terms of resilience compared to a highly efficient pure-variant network, especially by marked uncertainties.
The purpose of the study is to examine how international cooperation contributes to strengthening Kazakhstan's position as an educational hub. Although global academic partnerships are widely recognized major pillars of higher education modernization, few studies have explored Kazakhstan's strategic positioning and the management mechanisms supporting its internationalization efforts. This study introduces a novel comparative framework analyzing how Kazakhstan’s internationalization strategies differ from regional counterparts and evaluates the governance mechanisms shaping its academic partnerships.The methodology consists of a mixed-method approach, including statistical analysis, comparative assessment of universities rankings, as well as content analysis of academic reports. It uses a pragmatic research framework that combines quantitative and qualitative insights in understanding international cooperation: however, its impact faces challenges, including the limitations of secondary data since they can hardly showcase some of the vital institutional obstacles surrounding global academic collaboration.The novelty lies in the systematic evaluation of management strategies that further international partnerships in higher education in Kazakhstan. In contrast to past studies that largely dealt with the overall consequences of internationalization, this study additionally explores feedback mechanisms and strategic approaches that enable and enhance global engagements for universities.The findings show international partnerships improve the quality of education, curriculum development, influence research output, and attract foreign students and faculty. The study reveals that Kazakhstani universities are expanding their international networks even further despite the bureaucratic barriers and unequal institutional participation in international partnerships.This research contributes to the current discourse on higher education internationalization by means of taking Kazakhstan as a concrete case to demonstrate how targeted management strategies could make national education systems stronger in developing countries. Findings suggest specific practices for universities to enhance competitiveness and ensure sustainable growth in international academic cooperation.
The world economy is a system that is constantly evolving. Organizations must introduce creative initiatives in a competitive environment and abandon the usual business models to attract consumers. The global COVID-19 pandemic has thrown new challenges to the global economic system, driving it into a rigid survival framework. In such a situation, many organizations felt vulnerable and unable to compete. Others have begun to use innovative resources to retain their customers. The "service economy" concept has powerful potential for creating new opportunities in a crisis.The study aims to assess the Kazakhstani entertainment industry and predict development directions in the context of the global entertainment industry trends against the background of servitization processes. The research subject is the processes of servitization in the entertainment industry. The application of the positive approach resulted in the analysis of secondary information and quantitative research in the form of an online survey using the Google Form platform. When interviewing 60 respondents, non-probability convenience and judgmental sampling were used - the survey-involved students of Kurmangazy Kazakh National Conservatory and Al-Farabi Kazakh National University. The study's limitations are related to the study of show business, including music, cinema, and television. Looking at a broader range of entertainment industries requires more research. The conclusions drawn from the study results illustrate the typical situation for the Kazakhstani entertainment industry.
Background: Pregnancy care in the USA is in crisis, particularly in rural areas. Shortages and maldistribution of care are contributing factors. Family medicine (FM) physicians could be crucial to addressing the crisis.
Objectives: This study compared pregnancy and rural practice intentions of FM residents and FM obstetrics (FMOB) fellows, and current practices of FMOB fellowship alumni.
Method: In this cross-sectional survey study, 25 FM residents, 7 FMOB fellows, and 37 FMOB fellowship alumni completed practice intentions or actual practice surveys. Variables of interest included intention or practice in rural locations and medically underserved areas, and pregnancy-care intentions or practice, including items on delivery types and advanced obstetrics. We used Fisher’s exact test to compare residents, fellows, and alumni.
Results: Trainee intention and alumni practice were similar in practice characteristics except a higher rate of residents (80%) and fellows (100%) intended to practice in a medically underserved area (MUA) than alumni (29%) who practiced in an MUA (P < .001 and P = .001, respectively). Specific to pregnancy care, fellows and alumni respectively intended and provided low-risk, high-risk, and cesarean deliveries, and advanced obstetrics at higher rates than resident intentions.
Discussion: Results suggest FMOB fellows are more likely intend to provide pregnancy-related care compared to FM residents, and alumni provide pregnancy-related care at rates similar to fellow intentions. Few FM residents complete obstetrics fellowships. FMOB fellowships alone cannot sufficiently address care shortages. Expanding and promoting FMOB fellowships would increase the pregnancy -care workforce, but more is needed for FM to realize its potential to resolve the crisis.
This article investigates, for the first time, how quickly curious individuals can uncover the secrets behind popular magic tricks through internet research requiring minimal effort. To do this, 20 well-known magic tricks were selected, and the underlying trick secrets were sought using the AI assistant ChatGPT. It was found that using language assistants and the large language models behind them makes the search significantly more promising compared to recent keyword-based searches. For 18 of the 20 magic tricks, an explanation in the form of a descriptive text or an exposure video was found with little effort. The significance of this observation for the art of magic was not the main focus of this contribution, but the concluding section at least contains the author's initial thoughts on the matter.
Optimierung von Geschäftsprozessen ist ein wichtiges Thema in der Praxis und in der Ausbildung für (Wirtschafts‑)Informatiker. Gegenwärtig konzentrieren sich Beiträge in der Fachliteratur zur Prozessoptimierung hauptsächlich auf die Perspektiven von Prozesseigentümern und Management, die Zeit- und Kosteneinsparungen anstreben. Dadurch kann der Aspekt der In- und Exklusion von Personen bei der Digitalisierung von Geschäftsprozessen leicht aus dem Fokus geraten.
Der vorliegende Beitrag stellt eine Methode vor, die die Teilnehmer an Diskussionen zu Prozessverbesserungen dazu bringt, frühzeitig Aspekte der Zugänglichkeit in die Betrachtungen einzuschließen und in der Folge beim Prozessdesign zu berücksichtigen.
Dazu wurde ein Satz von Karten entwickelt, die mögliche Beweggründe dafür beleuchten, eine digitale Anwendung nicht nutzen zu können oder zu wollen. Das Nachvollziehen dieser Beweggründe soll helfen, das Design von Prozessen und Anwendungen zu verbessern.
Insbesondere wird über positive Erfahrungen beim Einsatz des Kartensatzes in der Hochschullehre im Fach Informatik berichtet.
Ziel dieser Arbeit war die Entwicklung eines dynamischen Verfahrens zur Leistungsmessung von Kraftfahrzeugen bei Manipulationsverdacht im Rahmen der Hauptuntersuchung. Ausgangspunkt ist das Problem, dass stationäre Prüfstände nicht immer verfügbar oder praktikabel sind, insbesondere bei dezentralen Prüfungen. Das entwickelte Verfahren basiert auf der Kombination eines externen Geschwindigkeitssensors mit einem im HU-Adapter integrierten Beschleunigungssensor. Anhand physikalischer Grundlagen wurde daraus die Radleistung berechnet, welche über einen antriebsartspezifischen Wirkungsgrad in die Motorleistung überführt und anschließend nach EWG korrigiert wurde.
Die durchgeführten Vergleichsmessungen auf einem Leistungsprüfstand zeigen Abweichungen zwischen 1,9 % und 31,8 % zur Referenz, bei gleichzeitig hoher Reproduzierbarkeit.
Die Ergebnisse belegen das prinzipielle Potenzial der Methode, liefern aber auch Hinweise auf notwendige Optimierungsschritte. Zukünftig ist die Weiterentwicklung hin zu automatisierter Synchronisation und benutzerfreundlicher App-Auswertung erforderlich, um eine praxistaugliche Integration in die Hauptuntersuchung zu ermöglichen.
