Abstract

Daily activity sees data constantly flowing through cameras, the internet, satellites, radio frequencies, sensors, private appliances, cars, smartphones, tablets and the like. Among all the tools currently used, mobile devices, especially mobile phones, smartphones and tablets, are the most widespread, with their use becoming prevalent in everyday life within both developed and developing countries. Shopping, reading newspapers, participating in forums, projecting and completing surveys, communicating with friends and making new ones, filing tax returns and getting involved in politics are all examples of how ingrained mobile technology is to modern lifestyleMobile devices allow a wide range of heterogeneous activities and, as a result, have great potential in terms of the different types of data that can be collected. The use of mobile devices to collect, analyse and apply research data is explored here. This book focuses on the use of mobile devices in various research contexts, aiming to provide a detailed and updated knowledge on what is a comparatively new field of study. This is done considering different aspects: main methodological possibilities and issues; comparison and integration with more traditional survey modes or ways of participating in research; quality of collected data; use in commercial market research; representativeness of studies based only on the mobile-population; analysis of the current spread of mobile devices in several countries, and so on. Thus, the book provides interesting research findings from a wide range of countries and contexts. This book was developed in the framework of WebDataNet’s Task Force 19. WebDataNet, was created in 2009 by a group of researchers focusing on the discussion on data collection methods. Supported by the European Union programme for the Coordination of Science and Technology, WebDataNet has become a unique, multidisciplinary network that has brought together leading web-based data collection experts from several institutions, disciplines, and relevant backgrounds from more than 35 different countries.

Abstract

Antibiotics and antibiotic resistance have most commonly been viewed in the context of human use and effects. However, both have co-existed in nature for millennia. Recently the roles of antibiotics and antibiotic resistance genes have started to be discussed in terms of functions other than bacterial inhibition and protection. This special topic will focus on both the traditional role of antibiotics as warfare mechanisms and their alternative roles and uses within nature such as antibiotics as signals or communication mechanisms, antibiotic selection at low concentrations, the non-specific role of resistance mechanisms in nature: e.g. efflux pumps, evolution of antibiotic resistance and the role of persisters in natural antibiotic resistance.

Abstract

The drive line of the working equipment of mobile machines is mainly composed of fluid power systems. Electro-hydraulic components facilitate the development of innovative Flow-on-Demand hydraulics. In these systems the oil flow of the pump is derived from the consumer requests and directly set in an open-loop control. Principle related power dissipation is reduced. Additionally, faster system response improves machine operability and ease of use.

Abstract

It becomes increasingly clear that the basis of antibiotic resistance problem among bacterial pathogens is not confined to the borders of clinical microbiology but has broader ecological and evolutionary associations. This Research Topic “Role and prevalence of antibiosis and the related resistance genes in the environment” in Frontiers in Microbiology, section Antimicrobials, Resistance and Chemotherapy, presents the examples of occurrence and diversity of antibiotic resistance genes in the wide range of environments, from the grasslands of the Colombian Andes, to the dairy farms and small animal veterinary hospitals in the United Stated, and to the various environments of Continental Europe and Indochina. Besides, various genetic mechanisms and selection/co-selection factors contributing to the dissemination and maintenance of antibiotic resistance genes are presented. The topic is finalized by the mathematical modeling approach to access the probability of rare horizontal gene transfer events in bacterial populations.

Abstract

Within this work, it is investigated under which conditions constant pressure systems with secondary controlled drives may be an energetic efficient and cost effective alternative to established mobile hydraulic circuit configurations. For this purpose, a methodology is introduced to evaluate chances and risks at employment of this technology in mobile machines. A demonstrator with three secondary controlled variable displacement drives is developed to confirm the results of the methodology.

Abstract

In this book a methodology for the evaluation of energy efficiency of mobile working machines by simulation is presented. It allows an efficiency analysis and systematic optimization of a single power train as well as a comparison of different power train concepts. The methodology is applied to a wheeled excavator. To ensure a realistic power demand in the simulation, a rule-based operator model is developed.

Abstract

The influence of the cell size of mobile communication networks onto the exposure to electromagnetic fields is investigated in this work. The exposure is assessed by means of a radio network planning. In a novel approach the path loss for the coverage and the path loss for the exposure are distinguished. The developed model is applied to different wave propagation models and cell structures. The results are discussed.

Abstract

An der Erforschung und Erprobung der mediengestützten Lern- und Arbeitsszenarien in Wissenschaft und Hochschule sind Expertinnen und Experten aus unterschiedlichsten Domänen beteiligt. Damit steht die Aktivität der Gesellschaft für Medien in der Wissenschaft (GMW) unter dem Zeichen der Interdisziplinarität. Bereits etabliert sind Fächerkombinationen wie die Mediendidaktik oder die Medieninformatik. Im wissenschaftlichen Alltag entstehen jedoch deutlich mehr interdisziplinäre Schnittstellen, deren Erörterung und Untersuchung das Thema der GMW-Tagung 2015 sind. Die Tagungsbeiträge finden sich in den Themenbereichen Digitale Medien und Interdisziplinarita¨t, Open Educational Resources, Gescha¨ftsmodelle sowie Gestaltung und Praxis wieder. Die GMW 2015 will den Diskurs zur Nutzung digitaler Medien in interdisziplinären Settings durch wissenschaftlich und praktisch fundierte Studien bereichern und konsolidieren.
