Flank wear estimation under varying cutting conditions

open access: yes, 1991
A model-based methodology, designed to operate under varying cutting conditions, for on-line estimation of flank-wear rate based on cutting force measurements is introduced.

The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

open access: yesBoreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

Phylogenomic analysis of ultraconserved elements clarifies relationships and morphological evolution in Cryptoplacoidea (Mollusca: Polyplacophora)

open access: yesCladistics, EarlyView.
Abstract Targeted enrichment of ultraconserved elements (UCEs) is a powerful tool for resolving phylogeny in groups with limited morphological or molecular data. Here, we use UCEs to reconstruct the first comprehensive phylogeny of the chiton superfamily Cryptoplacoidea, including museum material up to 133 years old.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

open access: yesCladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

A Novel Tool Condition Monitoring Technique of Determining Insert Flank Wear Width of Indexable Face Milling Tools Using On-Machine Laser Tool Setters

open access: yesMicromachines
Indexable face milling tools are often used to machine workpieces with large axial and radial depth of cuts, and thus, the inserts quickly wear out in machining.

Development of predictive force models for classical orthogonal and oblique cutting and turning operations incorporating tool flank wear effects [PDF]

open access: yes, 2006
Classical orthogonal and oblique cutting are the fundamental material removal or machining processes to which other practical machining processes can be related in the study and modelling of the machining processes. In the last century, a large amount of

Preprocessing missing data and partitions for phylogenetic analysis under dynamic homology, with application to museomics and phylogenomics

open access: yesCladistics, EarlyView.
Abstract In dynamic homology, data must usually be preprocessed to distinguish sequencing artefacts (missing data) from insertion–deletion events, but empirical studies using POY/PhyG have employed manual preprocessing. Here, we compare different procedures for handling missing data for dynamic homology, present Python scripts to automate these ...

Prurigo Pigmentosa – an increasingly diagnosed dermatological condition associated with ketogenic diet

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
SUMMARY Prurigo pigmentosa (PP) is a rare inflammatory dermatosis, clinically characterized by intensely pruritic, erythematous papules and papulovesicles, with reticular hyperpigmentation upon healing. We herein report four cases in adults of different ethnic backgrounds, in which the disease was associated with ketogenic metabolic states due to ...

Reimagining State Aid: Guiding Law and Policy Reform in a Changing World

open access: yesEuropean Law Journal, EarlyView.
ABSTRACT EU state aid law has shifted fundamentally from an originally purely repressive tool to a proactive steering mechanism for critical EU goals today. This paper argues that the current legal framework in Article 107 TFEU is gravely misaligned with this new function.

In-process monitoring of flank wear using motor torque command values on NC lathe

open access: yesNihon Kikai Gakkai ronbunshu
This paper investigates the feasibility of in-process flank wear monitoring using motor torque command values obtained from the internal sensors of an NC lathe without external sensors.
