In anisotropic media, the existence of leaky surface acoustic waves is a well-known phenomenon. Very recently, their analogs at the apex of an elastic silicon wedge have been found in experiments using laser-ultrasonics. In addition to a wedge-wave (WW) pulse with low speed, a pseudo-wedge wave (p-WW) pulse was found with a velocity higher than the velocity of shear bulk waves, propagating in the same direction. With a probe-beam-deflection technique, the propagation of the WW pulses was monitored on one of the faces of the wedge at variable distance from the apex. In this way, their depth structure and the leakage of the p-WW could be visualized directly. Calculations were carried out using a method based on a representation of the displacement field in Laguerre functions. This method has been validated by calculating the surface density of states in anisotropic media and comparing the results with those obtained from the surface Green's tensor. The approach has then been extended to the continuum of acoustic modes in infinite wedges with fixed wave-vector along the apex. These calculations confirmed the measured speeds of the WW and p-WW pulses.
Anisotropy has been found to play an important role for the existence of edge-localized acoustic modes as well as for nonlinear effects in rectangular edges. For a certain propagation geometry in silicon, the effective second-order nonlinearity for wedge waves was determined numerically from second-order and third-order elastic moduli and compared with the nonlinearity for Rayleigh waves propagating in the direction of the apex on one of the two surfaces forming the edge. In the presence of weak dispersion resulting from modifications of the wedge tip or coating of the adjacent surfaces, solitary pulses are predicted to exist and their shape was calculated.
This study investigates the impact of global payroll outsourcing on organizational efficiency and cost reduction based on the analysis of diverse implications stemming from thirty one (31) survey results. The findings reveal multifaceted challenges and benefitsassociated with outsourcing global payroll processing.
The research also unveils the most benefits of global payroll outsourcing. Notably, there's a consensus on the reduction in time-to-process payroll, cost per payroll processed, and improved payroll accuracy rate. Outsourcing streamlines processes, enhances operational efficiency, and contributes to faster, more accurate financial reporting.
Despite these benefits and challenges, statistical analysis reveals weak correlations between outsourcing global payroll and cost reduction or improved efficiency in various parameters, indicating a lack of a significant relationship. Consequently, the results, suggest no substantial correlation between global payroll outsourcing and enhanced efficiency or cost reduction based on this study's data.
Diese Arbeit befasst sich mit der Entwicklung eines umfassenden Konzepts zur Umsetzung des Lieferkettensorgfaltspflichtengesetzes (LkSG), welches ab dem 01.01.2024 für Unternehmen mit mehr als 1.000 Beschäftigten in Kraft tritt.
Die Bachelorarbeit ist in zwei Teile aufgebaut: zum einen den Theorieteil, der die Lieferkette in einem Verkehrsunternehmen und das Lieferkettensorgfaltspflichtengesetz umfasst, um eine Wissensbasis zu schaffen und zum anderen den Hauptteil, bestehend aus der Konzeptionierung. Da das Gesetz bereits im Jahr 2023 für große Unternehmen mit mehr als 3.000 Beschäftigten in Kraft trat, stehen bereits zahlreiche Systeme zur Unterstützung der Umsetzung zur Verfügung. Im Verlauf der Arbeit wurde eine Marktrecherche durchgeführt, bei der die geeignetste Softwarelösung für SWEG identifiziert wird. Um diese Untersuchung effektiv durchzuführen, wurden zwei Softwareauswahl-Tools entwickelt, die bei der Analyse und Bewertung helfen. Zusätzlich zum Software-Lösungsansatz wurde ein alternativer Lösungsansatz erarbeitet, der die eigenständige Handlung im Unternehmen vorsieht. Diese beiden Lösungsansätze werden zum Schluss verglichen, um die Geschäftsführung bei der Entscheidung, welche Version sie schließlich verwenden möchte, zu unterstützen.
Das erarbeitete Konzept bildet auch die Grundlage für die zukünftige Entwicklung und Umsetzung von Gesetzen und Richtlinien im Bereich Menschenrechte und Umweltaspekte. Für die Zukunft werden weitere Gesetze in Kraft treten, beispielsweise die kommende EU-Richtlinie.
Most E-Learning projects tend to separate learning activities from everyday work. This paper presents an approach where closer integration between learning and work is achieved by integrating multimedia services into manufacturing processes. The goal of E-Learning services integration in manufacturing is, through the development of new multimedia solutions, to accelerate and enhance the ability of manufacturing industry to capitalise on the emergence of a powerful global information infrastructure. In this paper we suggest to combine the areas of media streaming services and manufacturing processes, by providing electronic learning offerings as collections of media streaming services. The key components of our approach are 1) an xml based streaming service specification language, 2) automated configuration of distributed E-Learning streaming applications, 3) web services for searching, registration, and creation of E-Learning streaming services.
Integrating voice / video communication into business processes can accelerate resolution time, reduce mistakes, and establish a full audit-trail of the interactions. Some VoIP service providers offer website based or plugin based solutions, which are, however, difficult to integrate with other applications. A promising approach to overcome these disadvantages is the development of appropriate Web Services to allow applications interacting with a VoIP system. We propose a generic framework for VoIP applications consisting of an XML-based service specification language and a set of reusable Web Service components. Service providers using the proposed service-oriented architecture can offer to their customers a protocol-neutral Web Service interface, thus enabling the deployment of a general and integrated VoIP solution.
In this paper we suggest to combine the areas of media streaming services, mobile devices, and manufacturing processes to support monitoring, controlling and supervising production processes in order to achieve high levels of efficiency and environmentally friendly production. It contains a comprehensive and detailed explanation of the proposed E-Learning streaming framework, especially the adaption of streaming services to mobile environments. The key components of our approach are 1) an XML-based streaming service specification language, 2) adaption of multimedia E-Learning services to mobile environments, and 3) a media delivery platform for searching, registration, and creation of streaming services for mobile devices.
The need of suitable system of records in gaining ground as companies seek to maximize performance by harnessing the knowledge of their businesses, is discussed. Focused systems of record deliver a clear and consistent view even as they address a range of functions. Enterprise resource planning (ERP), as the financial system of record, embodies that view of manufacturing, inventory management, accounting and order processing. Customer relationship management (CRM), as a system of record, taps not only into the marketing and sales and service, but also into product development.
The central purpose of this paper is to present a novel framework supporting the specification and the implementation of media streaming services using XML and Java Media Framework (JMF). It provides an integrated service development environment comprising of a streaming service model, a service specification language and several implementation and retrieval tools. Our approach is based on a clear separation of a streaming service specification, and its implementation by a distributed JMF application and can be used for different streaming paradigms, e.g. push and pull services.
