In this study, we report on Total Electron Content (TEC) and Very Low Frequency (VLF) space measurements derived from Global Positioning System (GPS) and DEMETER satellites, respectively. These measurements are associated with the earthquake (EQ) of a magnitude of 6.3, which occurred on 6 April 2009, in L'Aquila (Italy). Anomaly features are derived from the analysis of TEC and VLF observations recorded two weeks before and after the seismic event occurrence. A TEC map with an interpolated regional pixel resolution of 1° × 1° × 15 min in latitude, longitude and time was generated, allowing for the checking of a possible presence of disturbances over the L'Aquila region. This analysis is combined with the study of the time profile associated to the VLF flux density variations recorded by the Instrument Champ Electrique (ICE) experiment on-board DEMETER satellite. We discuss, on the one hand, the combination efficiency of the electronic density and the VLF electromagnetic measurements and, on the other hand, the difficulty to distinguish between global effects and regional ones related to the earthquake. © 2011 Author(s).

Business process orientation means focusing on the organization's business processes instead of placing emphasis on functional structures or hierarchies. In this paper we discuss the approach of process cascading and segmentation, a design principle which helps organizations to build its structure around its customer-oriented business processes. Cascading of processes is an approach where the organization's business process design is based on internal customer-supplier relationships which ensure that every business process of the organization has a clearly defined (internal) customer which places an order and also receives the results. Segmentation of business processes refers to the idea of creating process variants of business processes which face heterogeneous market and/or customer. Both principles - cascading and segmentation of business processes - complement each other. We show how these design principles are applied in practice by using an Austrian manufacturing firm as a case study. © 2011 IEEE.

This paper outlines the increasing challenges and perspectives of service innovation in new business models and the relationship between service innovation and business development procedures such as service engineering and business model design concepts. It describes the main drivers of service innovation and identifies what makes service innovation so important today, consequences for (service) business modeling as well as the implications for an integrated development approach of service and business model innovation. A comparative analysis shows that in general Osterwalder's Business Model Design approach compliments the strategy-based service engineering process well in most areas. Using the toolbox of the Business Model Canvas complemented by specific methods and tools from the service engineering approach, new complex service systems can be developed in a systematic and holistic manner. Our findings from applying the theoretical results in a case study to developing a new business model for a cloud-based SaaS solution show that business modeling needs to be continuously cross-linked to the entire service engineering process to adapt to ever changing customer needs and vice versa. © 2012 IEEE.

Literature agrees that corporate culture is decisive for the success of business process management (BPM). A BPM-supportive culture is characterized by several facets, but it has not been examined so far how pronounced the single bricks are in corporate practice and which organizational characteristics are beneficial or detrimental to the development of a process culture. This paper addresses this gap and analyzes survey data of Austrian firms. Especially teamwork, customer focus, and lived processes by the management exhibit high levels of maturity. Backlog demand exists in regard to the use of a common process language. Whereas a company's age seems to hamper the achievement of cultural process maturity, the relative amount of BPM staff and the years of active BPM engagement are beneficial. © 2016 ACM.

This paper presents the results of an evaluation of the Performance Journey Mapping (PJM) framework. PJM is a service performance assessment concept with accompanying tools tailored to the specific performance measurement needs of small and medium-sized service providers. The initial evaluation of PJM was performed from three different perspectives. The underlying evaluation framework applied methodological triangulation in order to (i) ensure valid and reliable results and to (ii) evaluate both the framework’s results and its process. Quantitative results were supplemented with insights gained through participant observation. © 2016, University of Zagreb. All rights reserved.

This paper covers the development of a new stand-alone 3D finite element software package called "MSIM", which allows large deformation calculations as it occurs in the field of manufacturing technology. Since existing commercial software packages do need a lot of time to solve the highly nonlinear system of equations and do not often incorporate suitable elements as it is common in several forming processes, a new calculation program was implemented to remedy this deficiency. The first part of this work describes the development and the object-oriented implementation of the finite element program MSIM in C++, which is highly superior to commercial software packages with respect to calculation time and storage capacities. The parallelization of the assembly algorithm and the implementation of the solution algorithm for the highly nonlinear system of equations is one of the core issues. The second part focuses on the development of a novel solid-shell element and treats the locking phenomenon resulting from low order interpolation functions. The customized solid-shell element formulation is embedded in a static implicit total Lagrange formulation, which is able to deal with large deformations in accordance with the finite strain theory. For the constitutive relation, a hyperelastic material law was used in preparation to a further extension to a hyperelastic-plastic material behavior. Therefore, the determination of the elastic predictor gained from the right Cauchy Green strains, turned out to be a crucial step in hyperelasto-plasticity. Several benchmark tests were performed to evaluate the computing speed of the new calculation program MSIM and the accuracy of these solid-shell elements in comparison to the results attained by the FEM-package ANSYS.The developed calculation program serves as an effective tool to predict the stress-distributions inside the material under large deformations. Furthermore, this calculation program provides the basis for further improvements and enhancements and thus serves as an effective tool for research and teaching. ©. The results obtained so far agrees satisfactorily by gaining a significantly reduced calculation time.

The number of researches in the field of practical business process modeling (BPM) as well as process model (PM) quality and its influencing factors is very low. In this paper we address two aspects in that regard. We investigate the use of semiformal modeling languages in companies. To that end, we performed a pen and paper experiment involving 43 participants in 2011. Thereof, we derived four process design archetypes. The results reveal that formal BPM has still not been accepted as a useful practice in firms - mainly flowcharts are used for process design. We seize this circumstance in the second part of this work focussing on the comprehensibility of BPM languages. Based on the survey data of 77 employees obtained in 2012, we analyzed to what extent different PMs are understood by individuals. We found that the comic representation storyboard design is intuitive and easily understood. BPMN and UML also achieved good results, albeit subject to certain restrictions. Participants had problems with EPC and across all notations with concurrent activities. We therefore recommend the use of storyboards in field BPM as well as further accompanying investigations. © 2013 Springer-Verlag.

There is a remarkable lack of empirical studies investigating the importance of process ownership and continuous process improvement, two dimensions of business process orientation. This study addresses this issue and examines the joint effect of these two concepts on organizational performance. Based on a literature review possible questionnaire items for process ownership, continuous process improvement, financial performance, and customer satisfaction are identified. Data from 840 Austrian manufacturing and service companies are gathered and analyzed. The present empirical results show that firms applying continuous process improvement methods and having process owners in place gain the highest financial performance in relation to the industry average and the highest customer satisfaction compared to competitors. © 2012 IEEE.

The significance of approaches to technology-enhanced learning (TEL) has increased rapidly during the last few years. Nowadays in education different approaches such as game-based learning, web-based learning, video-based online courses, and many others are used on a daily basis. However, what defines the success of technology-enhanced learning approaches and how can such approaches be developed in a structured way? Furthermore, what different aspects have to be considered while doing so? To answer these questions, 4567 publications were analyzed in this present literature review in order to recognize the different aspects of implementing technology-enhanced learning approaches. Finally, 20 categories are defined in four main areas that summarize all the aspects in the field of technology-enhanced learning. Moreover, the study also reveals research areas that are important but hardly investigated in the observed journals of this study. © 2015 by the authors.

An organizational design based on process cascades is an approach where the business process design of the organization is based on internal customer-supplier relationships. The approach is based on the idea that, in general, each business process is activated by an order which is placed by another business process. The receiving process executes the order and delivers the results back to the ordering process. The ordering process therefore acts as an internal customer for the receiving process, which acts as an internal supplier. The approach is recursive, i.e. the supplier process may act itself as a customer process which places an order to a third process, and so forth. This paper discusses the idea of process-cascade based organizational design and empirically investigates the impact of such a design on firm performance. We find general support for this effect using carefully collected data from 114 manufacturing firms. © 2011 IEEE.
