Sediment Transport in the Piura River. Piura, Peru. An application with the HEC-RAS model.

This thesis is an investigation of sediment transport in the Piura River in Peru. Years of anthropogenic changes have redirected the river towards the south and have caused changes in the flow regimen (Alvarado Ancieta & Ettmer, 2007). It is suspected that the redirection towards the south has resulted in deposition of sediments which has reduced the capacity of the river in the lower reaches

Disentangling Regional Diversification : Identifying Theoretical and Empirical Challenges Through Complex Networks

Regional diversification has been positioned as a topic of great interest among researchers of economic geography, however, there remain some research gaps that must be attended to. Through the use of complex networks analysis from this literature in a period from 1975 to 2022, we identify some methodological and theoretical issues related to its measurement methods, the lack of an integrative fra

Effects of secular growth and mergers on the evolution of metallicity gradients and azimuthal variations in a Milky Way-like galaxy

We analyzed the evolution of the radial profiles and the azimuthal variations of the stellar metallicities from the VINTERGATAN simulation of a Milky Way-like galaxy. We find that negative gradients exist as soon as the disk settles at high redshift, and are maintained throughout the long-term evolution of the galaxy, including during major merger events. The inside-out growth of the disk and an o

A new specimen of Plesiopterys wildi reveals the diversification of cryptoclidian precursors and possible endemism within European Early Jurassic plesiosaur assemblages

A virtually complete and articulated plesiosaur skeleton (MH 7) is described from the Lower Jurassic (Toarcian) Posidonienschiefer Formation near Holzmaden in southern Germany. Plesiosaur remains are rare in this rock unit compared to those of other marine reptiles, such as ichthyosaurs and thalattosuchian crocodylomorphs. The new specimen offers an opportunity to assess the biodiversity of Early

ANN Based Fault Detection Classification in Power System Transmission line

The development of an artificial neural network to analyze power system faults is currently under way. However, the produced system is unsatisfactory because it is prone to failure and takes longer to detect faults. The ultimate goal of this project is to create an artificial neural network system that can identify and classify all forms of faults in power grid lines soon after they occur. In prin

Analysis of tool wear in micromilling Ti6Al4V and its impact on generated surface integrity

Tool wear is one of the dominant factors that impacts the surface integrity of machined materials. Understanding the impact of tool wear on surface integrity is crucial in micromilling, due to the size of the features being machined and the cutting tools. Therefore, this work aims to analyse the impact of tool wear on surface integrity during the micromilling of Ti6Al4V. In this context, microslot

High-throughput acoustofluidic device driven by an ElLIPtical Reflector Focusing Ultrasonic TranSducer (ELIPS)

Acoustofluidics is a promising technique for microparticle manipulation and has potential applications across various fields. However, its relatively low throughput limits wider applications. To overcome this challenge, we propose an ElLIPtical reflector focusing ultrasonic tranSducer (ELIPS) to drive bulk-wave-acoustofluidic devices, enabling high throughput. The ELIPS focuses transverse waves co
