Safety Approach of Detecting Abnormal Events (Spinning and Sliding) in Vehicular Systems
(2021)
The primary theme in the vehicles industry is the increase in automating and integrating more robust intelligent electronic systems to enhance the safe functioning, flexibility, and to extend the virtual productive age of the vehicular systems. Further, significant efforts focus on developing monitoring systems for the abnormal driving conditions such as wheel spinning and sliding that can increase the hazardous in the operating environment and speed up the wearing off process. Thus, these events play a primary role ...

Hot Work Tool Steel Processed by Laser Powder Bed Fusion: A Review on Most Relevant Influencing Factors
(2021-03-26)
As a representative of a common carbon-bearing hot work tool steel AISI H13 is in focus of the present review paper. Most relevant details for processing of AISI H13 by laser powder bed fusion (L-PBF) are systematically investigated. Three common stages of process parameter development and material assessment, respectively, are in focus: general processibility, process refinement, and deduction of process–microstructure–property relations, i.e., understanding of the interplay of relevant elementary mechanisms. On the ...

Financial Inclusion in the Global South: An Analysis of Index-Based Agricultural Insurance and Farmer Food Security in India
(2021-09-29)
Index-based agricultural insurance (IBAI) is presented by several development organizations as a highly effective way of mitigating climate change related risks and improving farmer food security. However, critics doubt the effectiveness of the instrument and regard it as a new frontier for capital accumulation. Linking to this debate, this research uses a qualitative design to investigate how IBAI affects the food production and consumption of farmers in the Indian state of Karnataka. It finds that the proposed ...

Robustness of portable and laboratory-based visible/near- and mid-infrared spectroscopy for optimized determination of temporally and spatially variable soil properties
(2021)
Application of visible/near- (VISNIRS) and mid-infrared (MIRS) spectroscopy to the field of soil science is promising, as it allows information about a range of properties to be collected simultaneously and rapidly, thereby providing high spatial and temporal resolution data for use in, e.g., soil mapping, precision agriculture, and long-term monitoring. However, investigation of the conditions under which visNIRS and MIRS can replace traditional lab methods is required, as the accuracy, robustness, and efficiency ...

Simultaneous impact modified and chain extended glass fiber reinforced poly(lactic acid) composites: Mechanical, thermal, crystallization, and dynamic mechanical performance
(2021-02-05)
Herein, glass fiber (GF) reinforced binary, ternary, and quaternary poly(lactic acid) (PLA) composites were prepared. Toughening, and chain extension of PLA was achieved through the incorporation of impact modifier and chain extender and their concurrent effects on the spectroscopic, crystallization, mechanical, thermal, and thermomechanical properties of the composites were investigated. High mechanical properties of GF influenced the mechanical performance of the composites. However, GF alone could not restrict the ...

Same Same But Different? A Two-Foci Perspective on Trust in Information Systems
(ScholarSpace, 2020-01-07)
Trust is one of the most important factors driving the adoption and use of information systems. The goal of this paper is to provide a first evaluation of a conceptual piece claiming a) that users distinguish between their trust in an IS and the provider of this IS and b) that both kinds of trust are important for the success sustainable success of IS providers. To evaluate the claims, a research model is developed and evaluated using data of 234 students during the introduction of a new IS at an European university. ...

Inwiefern wird das durch Macht strukturierte Wirkungsgefüge von Raum und Gender bereits in der Kindheit inkorporiert?
(2020)
Ausgehend von einer sozial strukturierten Wahrnehmung eines sozial strukturierten Raumes, die im Laufe der Sozialisation erlernt wird, geht die Arbeit der Frage nach, inwiefern es sich bei den im gesellschaftlichen Diskurs als frauen- und mädchenspezifisch verhandelten „Angsträumen“ um Fremd- oder auch um Eigenzuschreibung handelt. Da die gendertypische Sozialisation grundlegend in der Jugend passiert, ist die Verknüpfung von Angst und Raum bei Mädchen und jungen Frauen besonders aufschlussreich für die Frage, inwiefern ...

Review of Flux Interaction of Differently Aligned Magnetic Fields in Inductors and Transformers
(2020-12-24)
Magnetic devices are used in the majority of power electronic applications, e.g. power electronic converters, mains filters or burst/surge protection. Typically, they are the bulkiest and most cost-intensive components. Flux interaction of differently aligned magnetic fields in inductors and transformers can be one opportunity for size and cost reduction. It enables controllable magnetic devices through an additional manipulated variable to improve application design. The presented article gives an overview about ...

A Novel Approach to Robustly Determine Residual Stress in Additively Manufactured Microstructures Using Synchrotron Radiation
(2021-07-29)
In recent decades additive manufacturing (AM) for years has been in focus of academia and industry as its underlying production principle allows for the realization of designs of unprecedented geometrical complexity. However, often such structures are not realized due to the lack of understanding of structural and mechanical properties, this fact amongst others related to the unique microstructures established by the related processes. In this context, residual stresses, highly affected by the scan strategy and process ...
