Design of a 3D printed manual high flow pump
No full textThis project aimed to design a manual pump to transport low viscous fluid. It was designed according to some design requirements. Different types of pumps were compared, and then a pump was selected. Then the rotor was designed using SolidWorks. After making the CAD models, ANSYS Fluent (CFX) was used to perform Computational Fluid Dynamics (CFD) simulation to validate the result. Different components have been used to design the pump. The list was provided, and their functions were discussed. Then the guidelines for Additive Manufacturing (AM) were discussed, and the pump's casing was modified according to the AM guidelines. After modification of the design, the results were compared with the initial design
Irrglaube oder Wirklichkeit: Können narzisstische Individuen anderen verzeihen?
No full textDie vorliegende Arbeit untersucht den Zusammenhang zwischen Narzissmus und Verzeihen. Als weiterer möglicher Einflussfaktor wird die Emotionsregulation herangezogen. Mithilfe eines online Fragebogens, bestehend aus dem NPI-d-17, dem deutschen Vergebungsfragebogen und dem ERQ-d, wurden zwei Hypothesen untersucht. Die beiden Hypothesen umfassten 1) Je höher die Ausprägungen im Narzissmus, desto geringer sind die Werte im Verzeihen und 2) Der Zusammenhang von Narzissmus und Verzeihen wird durch die Fähigkeit zur Emotionsregulation beeinflusst. Es konnte eine Stichprobe von N = 119 Teilnehmenden generiert werden. Es konnte kein signifikanter Zusammenhang zwischen Narzissmus und Verzeihen mittels einfacher Korrelation gefunden werden. Ebenfalls konnte mithilfe einer multiplen Regression kein Einfluss der Emotionsregulation auf den Zusammenhang von Narzissmus und Verzeihen nachgewiesen werden. Somit müssen sowohl Hypothese 1 als auch Hypothese 2 verworfen werden.This paper examines the relationship between narcissism and forgiveness. Emotion regulation is used as another possible influencing factor. Using an online questionnaire consisting of the NPI-d-17, the German Forgiveness Questionnaire, and the ERQ-d, two hypotheses were examined. The two hypotheses included 1) The higher the expressions in narcissism, the lower the scores in forgiveness and 2) The relationship between narcissism and forgiveness is influenced by the ability to regulate emotions. A sample of N = 119 participants was generated. No significant correlation could be found between narcissism and forgiveness using simple correlation. Likewise, using multiple regression, no influence of emotion regulation on the relationship between narcissism and forgiveness could be demonstrated. Thus, both hypothesis 1 and hypothesis 2 must be rejected

No full textBetriebliche Gesundheitsförderung für haupt- und ehrenamtlich Mitarbeitende in der Freien Wohlfahrtspflege am Beispiel des AWO Kreisverband Kleve e.V.
No full textZiel dieser Arbeit war es, herauszufinden, welches Verbesserungspotenzial die Verwaltung des AWO Kreisverband Kleve e.V. hinsichtlich betrieblicher Gesundheitsförderung aufweist und welche ressourcenschonenden Maßnahmen zur Mitarbeitergesundheit beitragen. Die Ergebnisse zeigen, dass vor allem hinsichtlich ergonomischer Büroausstattung und Bewegung im Arbeitsalltag Handlungsbedarf besteht. Den Erkenntnissen nach empfehlen sich Maßnahmen wie die Anschaffung einheitlicher ergonomischer Bürostühle und die Förderung einer aktiven Pausengestaltung. Mithilfe von Apps und deren Erinnerungsfunktionen können bewusst lange Sitzeinheiten unterbrochen werden. Zudem eignen sich kleine Wettbewerbe und das Fahrrad-Leasing, um die körperliche Aktivität der Mitarbeitenden moderat anzuheben. Es stellt sich heraus, dass besonders die Veranstaltung eines Gesundheitstages bzw. einer Gesundheitswoche viele Vorteile miteinander verbindet und den Impuls gibt, sich mit dem Thema Mitarbeitergesundheit auseinanderzusetzen. Festzuhalten ist, dass die hier genannten Maßnahmen eine solide Basis schaffen und einen wichtigen Schritt in Richtung betriebliche Gesundheitsförderung bilden.
Als Ausblick in die Zukunft sollten die Maßnahmen kontinuierlich angepasst und nacheinander auf die einzelnen Zielgruppen – auch außerhalb der Verwaltung – zugeschnitten werden, sodass der AWO Kreisverband Kleve e.V. die Gesundheit all seiner Mitarbeitenden stärkt. Ferner sollte das Interesse der Mitarbeitenden an gesundheitsrelevanten Themen dazu genutzt werden, sie zu motivieren und darin zu bestärken, möglichst eigenverantwortlich und auch außerhalb der Arbeitszeit ein nachhaltiges gesundheitsförderndes Verhalten anzustreben. Darüber hinaus profitieren nicht nur die Mitarbeitenden von der Wertschätzung, sondern auch der Arbeitgeber, indem er auf dem Arbeitsmarkt wettbewerbsfähig bleibt. Gesunde, zufriedene und leistungsfähige Mitarbeitende sind der Schlüssel zum nachhaltigen Erfolg einer zukunftsorientierten Organisation und weitaus mehr als nur ein reiner Kostenfaktor
Continuous security testing for an existing client-server application
No full textDevSecOps has become a new paradigm in the technology world in a very short time. Despite the fact that there is a lot of talk about it, but in practice it is much more complicated. This paper shows one way to automate security testing on an established client-server application.
This research aims to find out if it is possible to improve quality standards by automating security testing and reducing human effort. One of the goals is to find reliable sources on information security management and practices known today. The next goal is to determine which components of the application to perform security analysis on.
We took the Open Web Application Security Project (OWASP) as a reliable source and began to examine the Top 10 web application security risks. The research needed to understand how this could be further applied to our client-server application.
As a result, we ran a manual experiment on the application following the OWASP Top 10 guidelines. After achieving some results in the manual experiment, we already had an idea of what to test and tools to automate.
We managed to automate 4 out of 10 categories, which took us about 2.5 months. On average, automated testing takes 38 minutes across 4 categories.
In conclusion, it should be noted that automating security testing costs a lot of effort and resources. Based on the example of our work, we can say for sure that it is necessary to properly prioritize resources and smoothly move to automation. The approach to cyber security analysis and automation will be different for each project. Nevertheless, information security in the vastness of the Internet was, is and will be, regardless of how technology evolves

Initial Exchange Offerings and the Presence of Underpricing
No full textCryptocurrency and blockchain entail various disruptive aspects, especially in finance.
One of them is the formation of new financing mechanisms through the offer of tokens.
Although they have opened new avenues for investors and allowed a vast number of entrepreneurs to raise a substantial amount of capital, the knowledge about their economic purposes and performance remains fragmented and heterogeneous. While initial coin offering (ICO) has been a more prominent focus in past studies, few to none encompass initial exchange offering (IEO). This paper is leveraged to address this gap and to provide a better understanding of IEO by primarily analysing the shift from crowdfunding, then, it considers the underlying technology and the wide variety of tokens. Subsequently, the main rationales are underlined, dividing into the incentives for both entrepreneurs and investors as well as challenges around the concept. Followed by an empirical examination and theoretical explanations for the findings of underpricing in this novel mechanism, in certain cases, results are connected to earlier ICO and IPO studies. For this research, a sample of 105 IEOs was manually collected and statistical descriptive tools, as well as a robust regression model, were conducted. It is discovered that the presence of underpricing is significant and IEOs are subject to heavy underpricing. Moreover, a set of variables that could influence the magnitude of underpricing was presented, suggesting for instance that greater issue size has significant effects whereas an optimistic market would likely increase underpricing

Market Participation of Maize Farmers Who Adopted Good Agricultural Practices (GAP) under the Mega Farm Project in the North of Thailand
No full textThe attempt to integrate Good Agricultural Practices (GAP) into the procurement standards of maize supply chain has been led by the Thai Feed Mills Association since 2015 to mitigate environmental impacts of maize production in the North of Thailand. Maize production was condemned by researchers and civil society as one of the culprits of deforestation and haze crisis. Up to now, maize in compliance with GAP in the North of Thailand is mostly produced as part of the Mega Farm Project and limited to a handful of farmers and planted areas. With rather unclear and unpromising circumstances, this study aims to examine the progress of GAP implementation and the market participation of farmers who adopted GAP. By using qualitative and quantitative research methods, it tried to find the reasons for the slow progress and limited coverage of GAP maize production. The results show that market incentives, institutional support, and farmers’ resource endowment are key determinants of GAP adoption and market opportunities. Although the government’s support under the Mega Farm Project has made GAP adoption accessible, affordable and achievable, the stagnation in GAP implementation and adoption is caused by a lack of market incentives, enforcement of regulations, engagement of the private sector, and government’s resources. Farmers’ market participation as a result of GAP adoption has not substantially changed over time. Their market access and prices received remained the same. Their market opportunities have not significantly been enhanced owing to the lack of market incentives for sustainable maize production, insufficient institutional support on harvest and post-harvest management, and farmers’ limited capacity to upgrade and reach an economy of scale
Feasibility check, design and dimensioning of a scrounger magnet coupling to a Siemens-E-Highway-truck
No full textAmong other factors, electric vehicles (EVs) were developed with the intention of mitigating the transportation sector’s impact on the environment and the depletion of fossil fuels. While various methods exist to charge electric vehicles (EVs) or extend their driving ranges, each have their benefits and drawbacks. As such, a method to accomplish the latter, i.e., to extend the driving range of an EV – and more specifically, a battery electric vehicle (BEV) – is proposed, which entails magnetically coupling to an electric truck (ET) ahead. This is enabled by a front-mounted system, comprised of a magnetic circuit (MC) and a linear axis (LA), which acts as a drawbridge to extend the MC ahead of the vehicle to a steel plate located at the rear of the ET. By utilising an array of permanent magnets (PMs) and a solenoid within a pot ferrite core (PFC) structure, the proposed system is able to easily generate a coupling force of around 6400 , which is sufficient to maintain the magnetic couple to the ET ahead, even under slight deceleration of the BEV of 2 ⁄ s^2, as it recuperates energy via regenerative braking. With the proposed system, a power gain of 30.24 is achievable in this manner, which allows for a significant improvement to the driving range of BEVs, as well as providing similar benefits as those offered by dynamic charging systems, namely, the convenience, and is thus regarded as a feasible solution, with regard to its performance
