The energy absorption of the wave energy converters (WEC) characterized by a limited stroke length —like the point absorbers developed at Uppsala University—depends on the sea level variation at the deployment site. In coastal areas characterized by high tidal ranges, the daily energy production of the generators is not optimal. The study presented in this paper quantifies the effects of the ch...

The energy conversion units and storage equipment connected to the multi-energy system are becoming diversified, uncertain factors brought by distributed wind power photovoltaic generation make flow structure more complex, which brings great difficulties modeling application of traditional hub methods. This study deeply analyzes coupling operation mechanism systems, carries out calculation anal...

Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....

Library and geography faculty at our institution consistently partner on integrating information literacy academic research skills into courses. Librarians typically create course guides as part of that effort. During the 2021–2022 year, we—an librarian a geographer liberal arts college—co-created an energy LibGuide intended to serve wider community. In this article, we detail collaborative pro...

Background Telestroke is recognized as a safe and time-efficient way of treating stroke patients. However, admission centers (spokes) are subject to financial charges which can make them reluctant to join the system. We implemented and assessed an economic model supporting our telestroke system, Virtuall, France, which includes one expert center (hub) and six spokes. Methods The model is base...

This paper investigates the uses of battery energy storage system (BESS) in ac networks highly populated with wind power generation. The investigation includes power system load leveling, frequency stabilization, and provision of reactive power support to the wind farm network. The BESS is connected to the wind farm main hub via voltage source converter, while the wind farm is connected to ac n...

This article addresses a digital twin-based real-time analysis (DTRA) to meditate the power system vulnerability whenever cascading failures and blackouts occur for any reason, thus, improve resiliency. In addition this, water-power package is proposed enhance vulnerable percentage of by promptly syringing energy grid under line/generator outage contingencies. To this end, in first place, we wi...

In this paper, we describe the BBN BYBLOS system used for the 1998 Hub-4E primary and Hub-4Sp evaluation benchmarks, and discuss the improvements made to the system in 1998. We focus on the techniques that were new in this year’s system, including processing of the acoustic training data, test segmentation, revised cepstral normalization and Vocal Tract Length Normalization (VTLN), band-specifi...
