A Theoretical Methodology and Measurement of Dynamic Characteristics of Wind Turbines with Composite Bucket Foundations

Journal of Marine Science and Engineering
A composite bucket foundation (CBF) is a new type of supporting structure in offshore wind engineering. Its huge transition part is the key difference compared to other offshore foundations.

Higher spatial resolution improves the interpretation of the extent of ventricular trabeculation

Journal of Anatomy, Volume 240, Issue 2, Page 357-375, February 2022., 2022
Jensen et al. show that higher spatial resolution may affect the sensitivity of diagnostic measurements of noncompaction and in addition could allow for novel measurements such as counting of trabeculations. Abstract The ventricular walls of the human heart comprise an outer compact layer and an inner trabecular layer.

An Improved Broadcast Authentication Protocol for Wireless Sensor Networks Based on the Self‐Reinitializable Hash Chains

Security and Communication Networks, Volume 2020, Issue 1, 2020., 2020
Broadcast authentication is a fundamental security primitive in wireless sensor networks (WSNs), which is a critical sensing component of IoT. Although symmetric‐key‐based μTESLA protocol has been proposed, some concerns about the difficulty of predicting the network lifecycle in advance and the security problems caused by an overlong long hash chain ...

Evaluation of Undrained Bearing Capacities of Wide‐Shallow Bucket Foundation with Honeycomb Bulkheads in Clay

Advances in Civil Engineering, Volume 2019, Issue 1, 2019., 2019
As a new type of offshore wind foundation, the wide‐shallow bucket foundation with honeycomb bulkheads mainly bears vertical, horizontal, and moment loads. As yet, no systematic study has been conducted regarding the effects of honeycomb bulkheads on the undrained bearing capacities of the wide‐shallow bucket foundation.

Spatial quantification of community resilience in contexts where quantitative data are scarce: The case of Muzarabani district in Zimbabwe

Geo: Geography and Environment, Volume 5, Issue 2, July-December 2018., 2018
Using the principal component analysis technique we analysed the overall and subcomponents of resilience to disasters in Muzarabani district, Zimbabwe. We found a geographic variation in community resilience across Muzarabani district, with the majority of the wards scoring low to below low levels of overall resilience. We conclude that quantifying and

A Novel Accuracy and Similarity Search Structure Based on Parallel Bloom Filters

Computational Intelligence and Neuroscience, Volume 2016, Issue 1, 2016., 2016
In high‐dimensional spaces, accuracy and similarity search by low computing and storage costs are always difficult research topics, and there is a balance between efficiency and accuracy. In this paper, we propose a new structure Similar‐PBF‐PHT to represent items of a set with high dimensions and retrieve accurate and similar items.

Accurate Counting Bloom Filters for Large‐Scale Data Processing

Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013
Bloom filters are space‐efficient randomized data structures for fast membership queries, allowing false positives. Counting Bloom Filters (CBFs) perform the same operations on dynamic sets that can be updated via insertions and deletions. CBFs have been extensively used in MapReduce to accelerate large‐scale data processing on large clusters by ...
