Small World Folksonomies: Clustering in Tri-Partite Hypergraphs
(2006-12-04)
Many recent Web 2.0 resource sharing applications can be subsumed under the "folksonomy" moniker. Regardless of the type of resource shared, all of these share a common structure describing the assignment of tags to resources by users.
In this report, we generalize the notions of clustering and characteristic path length which play a major role in the current research on networks, where they are used to describe the small-world effects on many observable network datasets. To that end, we show that the notion of ...

The future of people and nature in Southern Transylvania
(Pensoft Publishers Ltd., 2015)
Many things have changed in Southern Transylvania over the last 30 years – communism ended, the Saxons have all but left, Romania is now part of the European Union (EU), and people use mobile phones and computers. With this small book, we invite our readers to think about, and discuss, what might happen in Southern Transylvania over the next 30 years. What will communities feel like in 2043, what will the landscape look like, and what will happen to wild nature in the process? Nobody can predict precisely what the ...

Inclusive conservation and the Post-2020 Global Biodiversity Framework: Tensions and prospects
(2022-03-18)
The draft Post-2020 Global Biodiversity Framework commits to achievement of equity and justice outcomes and represents a “relational turn” in how we understand inclusive conservation. Although “inclusivity” is drawn on as a means to engage diverse stakeholders, widening the framing of inclusivity can create new tensions with regard to how to manage protected areas. We first offer a set of tensions that emerge in the light of the relational turn in biodiversity conservation. Drawing on global case examples applying ...

Investigation of potential drying strategies for quality maintenance of carrot
(2021-05-27)
Convective drying of carrots is a non-linear and unsteady-state process with simultaneous mechanism of heat and mass transfer leading to time varying quality changes along the process and finally causing irreversible quality modification. Inappropriate drying condition will generate many qualities related problems such as destruction of physical properties and discoloration of carrots causing by mechanical and thermal damage due to over-drying or extended drying periods. Inconsistent quality of the product was also ...

Ad-hoc Komposition optimaler Verarbeitungsketten für die Informationsextraktion aus heterogenen Produktpreisblättern
(2024)
Markttransparenz stabilisiert den Wettbewerb einer Branche, fördert Innovationen und schützt Endverbraucher vor hohen Kosten. Zur Schaffung dieser Transparenz bedarf es unabhängiger Unternehmen, die Informationen über die verschiedenen Anbieter und Produkte des fokussierten Markts sammeln. In vielen Branchen veröffentlichen die Anbieter dabei ihre Produktinformationen in individuellen Produktpreisblättern (PPB) und stellen diese in Form nicht maschinenlesbarer PDF-Dokumente auf ihren Webseiten zur Verfügung. Daraus ...

Exploring and Validating Construct Interpretations of Psychological Measurements
(2024)
In psychological research, as in other scientific disciplines, developing accurate measures of the phenomena under study is fundamental to maintaining the integrity of scientific conclusions. Psychological researchers are often criticized for a lack of rigor when it comes to measurement. On closer inspection, however, these problems may be due not only to the lack of implementation of common standards, but also to fundamental methodological flaws in those standards. Measurement methodology within psychological research ...

Index Archiv für Eisenbahnwesen 1878 bis 1936
(2024)
Der Index der Verkehrszeitschriften aus den Jahren 1878 bis 1942 geben einen Blick in den Aufstieg der Verkehrssysteme des fossilen Kapitalismus und die koloniale Expansion der Eisenbahn nach Asien, Afrika und Lateinamerika. Ohne Eisenbahntransporte wäre eine flächendeckende Versorgung mit dem Brennstoff Kohle unmöglich gewesen, der die Produktionsmaschinen des Industriekapitalismus antrieb. Das Big Oil ermöglichte den Betrieb von Personenkraftwagen und Lastkraftwagen auf einem Straßennetz, das infolge der steigenden ...

Enhanced Methods for Performance Evaluation and Fault Detection of Concentrating Solar Process Heat Plants
(2024)
Accurate measurements of direct irradiance are required for precise performance analysis and fault detection of concentrating solar process heat plants for industrial processes (CSHIP). For this reason, a cost-effective and low-maintenance pyranometer SPN1 has been investigated by comparing four years minute mean direct normal irradiance measurements of a SPN1 to a reference pyrheliometer at the Institute for Solar Technology SPF in Rapperswil (Switzerland). A significant overestimation of the direct normal irradiance ...

Development of decentralized solar-assisted yogurt processing unit for the production of on-farm high-quality yogurt
(2024)
In Pakistan, the dairy sector represents a significant part of agricultural production and is an important source of income, especially for small farmers. Yogurt production at the farm level is important for adding value to the milk. In this study, a solar-assisted yogurt processing unit capable of performing three processes of heating, fermentation, and cooling in a single unit was developed. It consisted of a circular chamber surrounded by a coil for heating by a solar vacuum tube collector and a pillow plate for ...
