    A Common Tool for Managing Environmental Monitoring Data
    (EnviroInfo Dessau 2012, Part 2: Open Data and Industrial Ecological Management, 2012) Rüther, Maria; Bandholtz, Thomas; Schulte-Coerne, Till
    This article gives an overview of a recent project of the German Environmental Specimen Bank (ESB) regarding the management of its data. It describes the user requirements, both from the perspective of the scientists as well as of application management, which have led to the development of a general tool for managing environmental data. Examples demonstrate the flexible structure of the new application and thus give an impression for possible use in other monitoring programs. Thereafter, we examine the German ESB’s open data, which is a part of the Federal Environment Agency’s Linked Open Data initiative.

    A Content Platform for Smartphone-based Mobile Augmented Reality
    (EnviroInfo Dessau 2012, Part 1: Core Application Areas, 2012) Fuchs-Kittowski, Frank; Simroth, Stefan; Himberger, Sebastian; Fischer, Fabian
    Mobile Augmented Reality (mAR) is thought of having an enormous economic potential. But the commercial success still depends on the availability of AR content. In this paper a content platform for the efficient realization of AR applications on mobile devices (Smartphones) is described. Requirements for such a mAR content platform are derived based on application fields in flood management. Then, the concept and implementation of an AR content platform are described covering the whole content creation process. Besides, mAR apps in the field of flood management based on this platform are presented.

    A Model-Based Approach to High Performance Phenotyping
    (EnviroInfo Dessau 2012, Part 1: Core Application Areas, 2012) Steinhage, Volker; Schöler, Florian; Balfer, Jenny
    Breeding pest resistant crops can reduce the application of plant protection products. This in turn will significantly reduce biotical stress of the plants, and damage to the environment. To enable greater efficiency in crop breeding and to optimize decision making in crop management, there is an increasing demand for non-biased and faster assessment of plant traits in lab and field. Within a subproject of CROP.SENSe.net, an interdisciplinary research network of Bonn University and the research centre Jülich, we are working on a non-destructive solution to analyze and screen plant phenotypes. We aim for complete and precise 3D reconstructions of plants based on sensor data. To meet the challenge of occlusions and self-occlusions in sensor-based measurements, we employ a model-based approach "to make hidden object parts visible." First results show that important breeding characteristics can be derived by combining the visible exterior plant components with the model-induced interior plant components.

    A Quest for Affordable Personalized Atmospheric Exposure Estimates
    (EnviroInfo Dessau 2012, Part 1: Core Application Areas, 2012) Kobernus, Michael; Havlik, Denis; van der Schaaf, Hylke; Pielorz, Jasmin; Falgenhauer, Markus
    From the moment of our birth until our very last breath, we spend our lives immersed in a mixture of gases and aerosols known as "the air" or "atmosphere". Our largest organ, our skin, as well as our eyes are constantly exposed to the atmosphere, and an average adult inhales and exhales close to ten litres of air each minute while at rest, while during heavy exercise, this volume will rise steeply and could be as high as 150-250 litres per minute. Unsurprisingly, our well-being is closely connected to the characteristics of the air: some of the gases and chemicals suspended therein are toxic, others may cause allergic reactions, and our bodies are also sensitive to changes in e.g. humidity or oxygen levels as well as to changes in the air temperature and pressure. With the exception of the relatively rare cases of immediate lethal dangers (e.g. due to fires or chemical accidents), physical and chemical changes in atmospheric conditions can result in: (1) immediate or short term risks including skin and eye irritation, drying and watering of the eyes, respiratory difficulties, headaches and general feeling of malaise; and (2) medium to long term health damage to respiratory and immune systems. Moreover, sensitivity to these changes is both very different from one person to another and in many cases highly dependent on the individual’s patterns of behaviour. Yet, while each individual has a unique relationship to the environment, the information on the state of atmosphere and related hazards available today is entirely generic, and by no means personalised. We intend to address this lack of individualized information through the development of an affordable “Personal Environmental Information System” (PEIS). This system will allow users to estimate personalized exposure to various atmospheric stressors as well as to calculate the personalized risk index resulting from these hazards, individual sensitivities and individual behavioural patterns.

    A Toolbox for Building up Process-based, Macro-economic Material Flow Models
    (EnviroInfo Dessau 2012, Part 2: Open Data and Industrial Ecological Management, 2012) Weidemann, Rainer; Poganietz, Witold-Roger; Lutz, Richard; Grieß, Christina
    Using the example of CarboMoG, the Carbon Flow Model of Germany, structures and processes for process-based, macro-economic material flow models were analyzed. The aim is to create a toolbox, which can be used to assemble models of this kind from building blocks, to parameterize and calculate a model, and then to use the model for analysis tasks. It was investigated whether and how toolkits existing in the fields of material flow analysis and life cycle assessment could also be used for process-based, macro-economic material flow models. Unfortunately, it was found that no product could be used without massive adaptations. Thus, the development of an own toolbox was initialized.

    Advanced control system for municipal wastewater treatment plant
    (EnviroInfo Dessau 2012, Part 1: Core Application Areas, 2012) Stachura, Marcin; Janiszowski, Krzysztof
    In this paper a proposal of a predictive control of a wastewater treatment plant was presented. Proposed multilayer control structure is composed of direct access PID controllers and supervisory DMC (Dynamic Matrix Controller) predictive controller. Basic idea of applied multilayer control structure was to use DMC controller to predict and compensate present and future measurable disturbances (flow and load of a crude sewage). Validation of presented approach was performed with use of computer simulations with different disturbance scenarios. The research was based on data obtained from a wastewater treatment plant in Resovia.

    Analysing Health Risks from Air Pollution Effects in Saxony, Germany
    (EnviroInfo Dessau 2012, Part 1: Core Application Areas, 2012) Richter, Silke; Wiemann, Stefan; Karrasch, Pierre; Kadner, Daniel; Brauner, Johannes; Siegert, Joachim; Rossmann, Julia; Elsner, Bernhard; Arloth, Jana
    This article presents the approach and current findings of the EO2HEAVEN project, in particular from the Saxony Case Study. The aim of the Case Study is the conceptual design of a Spatial Information Infrastructure for better understanding the complex relationship between ambient air quality and its influence on the human health. This includes air quality modelling and a statistical analysis of health datasets as well as the development of a service infrastructure offering access, analysis and visualization of environmental and health information.

    Analysis and evaluation of mobile apps with regard to resource efficiency and data volumes - Methodologies and tools
    (EnviroInfo 2022, 2022) Obergöker, Kira
    The impact of software on energy and resource consumption is receiving more and more attention. While the examination of desktop software already provides initial sresults and criteria for its evaluation, the consideration of mobile apps is not quite as advanced. This paper is a first step to get an overview of which methods and tools can be used to analyse the resource and data consumption of mobile apps and to evaluate their sustainability. First, I present the previous criteria for desktop software products. In the next step, I present an existing measurement environment for determining the data volume of mobile apps. I created simple environments to identify and test components that can be used to build new measurement environments. I evaluate and compare the measurement environments based on their results. This showed variations between the environments, but an internally equal proportionality. Finally, I used the results obtained to consider how mobile apps can be analysed in terms of their resource consumption, as well as
