Random Guessing for Beam Alignment: A Low Complexity Strategy for Reducing Blockage in mmWave Communications

open access: yesIEEE Access, 2022
High frequency (millimeter wave and higher) systems are being used for curb-to-home services and indoor networks with fixed transmitter and receivers. However, the environment between them can shift due to moving flora and fauna causing sudden blockages.

A co-phase matrix to guide simultaneous multithreading simulation [PDF]

open access: yesIEEE International Symposium on - ISPASS Performance Analysis of Systems and Software, 2004, 2004
Several commercial processors have architectures that include support for simultaneous multithreading (SMT), yet there is still not a validated methodology for estimating the performance of an SMT machine that does not rely on full program simulation.

Towards Piston Fine Tuning of Segmented Mirrors through Reinforcement Learning

open access: yesApplied Sciences, 2020
Unlike supervised machine learning methods, reinforcement learning allows an entity to learn how to deploy a task from experience rather than labeled data.

Smart co-phasing system for segmented mirror telescopes [PDF]

open access: yesSPIE Proceedings, 2016
Space observations of fainter and more distant astronomical objects constantly require telescope primary mirrors with a larger size. The diameter of monolithic primary mirrors is limited to 10 m because of manufacturing and logistics limitations. For space telescopes, monolithic primary mirrors are limited to less than 5 m due to fairing capacity ...

stLFRsv: A Germline Structural Variant Analysis Pipeline Using Co-barcoded Reads

open access: yesFrontiers in Genetics, 2021
Co-barcoded reads originating from long DNA fragments (mean length >30 kbp) maintain both single base level accuracy and long-range genomic information. We propose a pipeline, stLFRsv, to detect structural variation using co-barcoded reads.

A rapid molecular approach for chromosomal phasing. [PDF]

open access: yesPLoS ONE, 2015
Determining the chromosomal phase of pairs of sequence variants - the arrangement of specific alleles as haplotypes - is a routine challenge in molecular genetics.

Port Development and the Environment: External Costs from Dredge Disposal and Air Pollution [PDF]

open access: yesJournal of International Logistics and Trade, 2004
This paper analyzes two external costs often associated with port development, cost to fisheries from marine dredge disposal and damages from air pollution, using estimates of development and operation for a proposed (but since cancelled) container port ...

Stakeholder-guided, model-based scenarios for a climate- and water-smart electricity transition in Ghana and Burkina Faso

open access: yesEnergy Strategy Reviews, 2023
In support of West Africa's potential energy transition under climate change, an international team of scientists and a wide range of local stakeholders in Ghana and Burkina Faso jointly assessed different mitigation and adaptation pathways for energy ...

Evaluation of seasonal atmosphere–biosphere exchange estimations with TCCON measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
We evaluate three estimates of the atmosphere-biosphere exchange against total column CO2 observations from the Total Carbon Column Observing Network (TCCON).

Scenarios for Coal-Exit in Germany—A Model-Based Analysis and Implications in the European Context

open access: yesEnergies, 2020
The political discussion to reduce the carbon footprint of Germany’s electricity sector, focusing on coal, is intensifying. In this paper, we develop scenarios for phasing out lignite and hard coal power plants in Germany prior to the end of their ...
