Cutting tool condition monitoring using eigenfaces : tool wear monitoring in milling Anzeigen

Effective monitoring of the tool wear condition within a machining process can be very challenging. Depending on the sensors used, often only a part of the relevant wear information can be detected. In the case of milling processes data acquisition is made even more difficult&...

Biocides in soils of urban stormwater infiltration systems : indications of inputs from point and non-point sources Anzeigen

AbstractUrban stormwater contains various micropollutants, such as biocides, which are washed off from facades during wind-driven rain events. Biocides can reach the groundwater via stormwater infiltration systems (SIS), although the soil layer acts as a reactive barrier preventing the leaching o...

Designing a computational thinking intervention for kindergarten students Anzeigen

In recent years, the emphasis on Future Skills - such as Communication, Critical Thinking, Creativity, Cooperation, and Computational Thinking (CT) - has significantly increased in K-12 education, as these skills can empower students to understand new phenomena that shape society. Various co...

Plants as inspiration for material-based sensing and actuation in soft robots and machines Anzeigen

Because plants are considered immobile, they remain underrepresented as concept generators for soft robots and soft machines. However, plants show a great variety of movements exclusively based on elastic deformation of regions within their moving organs. The absence of gliding parts, as...

Physics-driven machine learning : from biomolecules to crystals Anzeigen

Physical systems and their interactions exhibit inherent equivariance. In machine learning (ML), predicting quantities derived from these interactions follows two main approaches: constructing invariant scalar features as inputs to invariant models or employing equivariant models directly. This thesis focu...

Constructing platform capitalism : inspecting the political techno-economy of Building Information Modelling Anzeigen

How to do human evaluation : a brief introduction to user studies in NLP Anzeigen

Molecular mechanics of disordered solids Anzeigen

Disordered solids are ubiquitous in engineering and everyday use. Although research has made considerable progress in the last decades, our understanding of the mechanics of these materials is, at best, in an embryonic state. Since the nature of disorder complicates the realization of&#...

Technology selection for holistic analysis of hybrid-electric commuter aircraft Anzeigen

Electric powertrains have different characteristics than conventional powertrains with combustion engines and require unconventional aircraft designs to evolve their full potential. Therefore, this paper describes a method to identify potential aircraft designs with electrified powertrains. Promising technology ...

A fine-grained data set and analysis of tangling in bug fixing commits Anzeigen

Context: Tangled commits are changes to software that address multiple concerns at once. For researchers interested in bugs, tangled commits mean that they actually study not only bugs, but also other concerns irrelevant for the study of bugs. Objective: We want to improve ou...

End-effector trajectory tracking of flexible link parallel robots using servo constraints Anzeigen

We apply the concept of servo constraints to end-effector trajectory tracking control of parallel robots with structural link flexibilities. Such servo constraints deliver the inverse robot model where solution approaches via projections are proposed, which transform the resulting differential-algebraic&#x...

The Fermi energy as common parameter to describe charge compensation mechanisms : a path to Fermi level engineering of oxide electroceramics Anzeigen

Chemical substitution, which can be iso- or heterovalent, is the primary strategy to tailor material properties. There are various ways how a material can react to substitution. Isovalent substitution changes the density of states while heterovalent substitution, i.e. doping, can induce elec...

Synthetic and structural peculiarities of neutral and cationic molybdenum imido and tungsten oxo alkylidene complexes bearing weakly coordinating N‐heterocyclic carbenes Anzeigen

The syntheses of the neutral molybdenum imido alkylidene N-heterocyclic carbene (NHC) complexes of the general formula [Mo(NAr)(CHCMe2Ph)(NHC)XY] (Ar=2-tBu-C6H4, 2-CF3-C6H4, 2,6-Me2-C6H3, 2,6-Cl2-C6H3, adamantyl; X, Y=OTf, OC(CF3)3, OCH(CF3)2, OC6F5, SC6F5, 2,5-bis(pentafluorophenyl)phen-1-yl) bearing electron-withdrawing NHCs (1,3-dim...

Approximation of a two‐dimensional Gross-Pitaevskii equation with a periodic potential in the tight‐binding limit Anzeigen

The Gross-Pitaevskii (GP) equation is a model for the description of the dynamics of Bose-Einstein condensates. Here, we consider the GP equation in a two‐dimensional setting with an external periodic potential in the x‐direction and a harmonic oscillator potential in the y‐direction in the&...

Optimierung des örtlichen Auflösungsvermögens in der aktiven Thermografie durch eine Lockin-Kompensationsmethode und der KI-gestützten Invertierung thermischer Wellen Anzeigen

Die aktive Thermografie (TT) nutzt den natürlichen diffusen Wärmefluss, um aus der gemessenen Oberflächentemperatur Rückschlüsse auf die innere Struktur von technischen Bauteilen oder biologischen Proben zu ziehen. Allerdings beeinträchtigt die Diffusion thermischer Wellen und der dadurch induzierte laterale&#x...
