The effective, efficient and continuous execution of business processes is crucial for meeting entrepreneurial goals. Business process modeling and simulation are used to enable desired business process optimizations. However, current approaches mainly focus on economic aspects while security aspects are dealt with in separate initiatives. This missing interconnection may lead to significant differences in improvement suggestions, such as the differing valuation of security investments (e.g., redundancy of systems). The major contribution of this paper is the introduction of a formal model that is capable of expressing the relations between threats, detection mechanisms, safeguards, recovery measures and their effects on business processes. This novel business process simulation capability paves the way for the evaluation of security investments at process design stage by allowing the consideration of stochastic influences of the occurrence of threats on process activities and resources in a unified way. A stylized business case outlines how our method can be applied to real world scenarios. © 2011 IEEE.

Many structures resting on pile foundations, which are surrounded by water in the soil for decades or centuries. In the context of status explorations or assessments questions arise concerning their conservation status and their durability. - The paper presents the results of extensive in situ studies and laboratory tests, which were performed on older wooden pile foundations of port facilities, bridges and building foundations in the framework of planning of maintenance measures. In the focus of this work are studies on the biotic attack to the woods and its effect on the density and strength characteristics of the piles. Inter alia, the investigations have revealed that the wood under the said anaerobic conditions suffers deterioration due to bacterial attack, rarely by higher fungi. As discovered by microscopic investigations on thin sections, the bacterial attack appears as a partial degradation in the individual wood cells, especially in the middle lamella of the late wood cells and the dots. As indicated by the results of the density and strength test results, the bacterial attack is - compared to fungal attack - a very slow but steady process. It causes also strength reduction of the woods and losses of the load bearing capacity of the structures, and has to be taken into account in the static assessments. © (2014) Trans Tech Publications, Switzerland.

Purpose: While almost all life cycle assessment (LCA) studies published so far are based on generic vehicles, type approval energy consumption as well as emission data, and application scenarios related to standardized laboratory-based driving cycles, this projects aims at quantifying the LCA based on a real-world vehicle composition and energy consumption data measured before and after the electric conversion of a mini class car. Furthermore, consequences of a second life of a vehicle’s glider on the environmental impact were investigated. Methods: After having driven 100,000 km, a Smart was converted from combustion to electric in a laboratory project. The inventory was developed grounded upon materials data from laboratory measurements during the conversion process as well as on real-world energy consumption data prior and after the conversion. Three base models are compared in this life cycle impact assessment: a conventional new Smart (combustion engine), a new electric Smart, and a Smart converted from combustion engine to electric. Together with two sensitivity analyses (four different electricity mixes as well as urban vs. mixed driving conditions) and two EOL treatments, 36 scenarios have been quantified. The inventory is based on Ecoinvent database v 2.2 as a background system and includes raw material extraction. Results and discussion: In urban use, the modeled battery electric vehicle has a favorable environmental impact compared to the ICEV even when charged with the German electricity mix of the year 2013. The advantage in summed up endpoints of the converted Smart is 23 % vs. the new electric Smart on average for the mixed driving conditions and 26 % for the urban driving conditions, respectively. Over a variety of impact categories, electricity consumption during battery cell production in China as well as impacts due to microelectronic components dominated the life cycle. Results for 18 midpoint categories, endpoints for damages to human health, to resource quality and to ecosystem quality as well as the Single score endpoints are reported. Conclusions: This investigation points out that real-world treatments in inventory development can more specifically outline the environmental advantages of the electric car. The electric conversion of a used combustion engine vehicle can save an additional 16 % (CO2-eq) and 19 % (single score endpoints) of the environmental impact over a lifetime, respectively, when compared with the new BEV. © 2015 Springer-Verlag Berlin Heidelberg

The SGL market knowledge contains a wide range of Electric Arc Furnace installations. Design and operational basics of more than 800 melting furnaces (AC and DC) were correlated with the Graphite Electrode application (450-800 mm) to evaluate technical trends and developments. This paper describes how to use the operational experience to compare the individual melting furnace with Benchmark furnaces. By this, the status of the operational effectiveness will be defined and compared with other furnaces. Further, the results of the Benchmark Analysis helps to define the next development steps - without or with capital investments.

Some of the important considerations while producing attractive concrete surfaces through the addition of pigments are discussed. One of the main demands made on the pigment is that it is absolutely resistant to alkalis, or the coloring effect of the pigment must not be impaired by the lime content of the cement. White colors can be created with titanium dioxide pigments, and blues with lightfast pigments if the concrete is made with a light-colored cement. Purchase of all the cement from the same supplier is recommended as this practice can eliminate any fluctuations in color due to differences in the color of the cement. Accurate control of the water supply in a concrete mixing unit is an integral part of efficient concrete production. Care should be taken with the choice of release agent, if too much release agent is applied, it can get on to the fresh concrete and stain the surface.

Single plant traits such as green biomass, spike dry weight, biomass, and nitrogen (N) transfer to grains are important traits for final grain yield. However, methods to assess these traits are laborious and expensive. Spectral reflectance measurements allow researchers to assess cultivar differences of yield-related plant traits and translocation parameters that are affected by varying amounts of available N. In a field experiment, six high-yielding wheat cultivars were grown with N supplies of 0, 100, 160, and 220kg N ha-1. Wheat canopies were observed spectrally throughout the grain-filling period, and three spectral parameters were calculated. To describe the development of the vegetative plant parts (leaves + culms) and the spikes, plants were sampled four times during grain filling. Dry weights and the relative dry-matter content were recorded for leaves + culms and spikes. The N status of the plants was assessed by measuring the total N concentration and by calculating the aboveground N uptake. Good correlations were found between spectral indices and single plant traits throughout grain filling but varied with N supply and development stage. The normalized difference vegetation index, NDVI, was strongly affected by the saturation effects of increased N concentration. The red-edge inflection point, REIP, predicted plant traits with r2 values up to 0.98. However, in plants with advanced senescence, the REIP was less efficient in describing plant traits. The NIR-based index R760/R730 was closely related to yield-related plant traits at early grain filling. Compared to the REIP, the R760/R730 index was resistant to strong chlorophyll decays being able to predict plant traits at late grain filling, with r2 values of up to 0.92. Spectral reflectance measurements may represent a promising tool to assess phenotypic differences in yield-related plant traits during grain filling. © 2013 WILEY-VCH Verlag GmbH & Co.

The German health care market is under a rapid rate of change, forcing especially hospitals to provide high-quality services at low costs. Appropriate measures for more effective and efficient service provision are process orientation and decision support by information technology of clinical pathway of a patient. The essential requirements are adequate modelling of clinical pathways as well as usage of adequate systems, which are capable of assisting the complete path of a patient within a hospital, and preferably also outside of it, in a digital way. To fulfil these specifications the authors present a suitable concept, which meets the challenges of well-structured clinical pathways as well as rather poorly structured diagnostic and therapeutic decisions, by interplay of process-oriented and knowledge-based hospital information systems. © 2010 Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering.

Cloud computing is an emerging technology that offers opportunities for organisations to hire precisely those ICT services they need (SaaS/PaaS/IaaS). Small and medium sized enterprises (SMEs) can benefit a lot from software services that are managed in a professional way. Cloud computing enables them to overcome restrictions from low budgets and limited resources for ICT. However, cloud adoption is challenging and requires a clear cloud roadmap. Organisations lack knowledge of cloud computing and are usually challenged by the adoption of cloud services. In most cases, SMEs do not know what aspects they have to take into consideration for a sound decision in favour or against the cloud. A cloud readiness assessment is a general approach to facilitate this decision-making process. The presented study focuses on the development of an assessment framework for cloud services (SaaS) in the domain of enterprise content management (ECM) and social software (e-collaboration). © 2015 IEEE.
