Breeding high-value oat varieties that meet milling industry standards is crucial for satisfying the demand for oat-based food products and for supporting oat growers. Test weight, thins percentage, and groat percentage are traits that define oat milling quality and the final price of food-grade oats. Conventional selection for milling quality is costly and impossible in early generations. Multi-trait genomic selection (MTGS) combines genomics and phenomics using genome-wide markers and phenotypic informationm from relatives and selection candidates to predict the breeding values. MTGS use phenotypic information on economically important primary trait and secondary traits that are genetically correlated with the primary trait. MTGS enables intensive phenotyping and significantly accelerates the rate of genetic gain for milling quality. The objective of this study was to evaluate different MTGS models that use morphometric traits to improve accuracy for primary oat grain quality traits for their potential to enhance breeding for oat grain quality. We evaluated 558 breeding lines from the University of Illinois at Urbana-Champaign Oat Breeding Program across two years for primary milling traits, test weight, thins, and groat percentage, and secondary grain morphometric traits derived from kernel and groat images. Kernel morphometric traits were genetically correlated (rg> 0.3) with test weight and thins percentage but were uncorrelated with groat percentage. For test weight and thins percentage, the MTGS model that included the kernel morphometric traits in both training and candidate sets outperformed single-trait models by 52% and 59% respectively. In contrast, MTGS models for groat percentage were not significantly better than the single-trait model. When using kernel morphometric traits from a single replicate, MTGS was 36% and 55% more accurate than the single-trait model for test weight and thin percentage, respectively. Overall, we found that incorporating kernel morphometric traits can improve the genomic selection for test weight and thin percentage in oat. However, further research is needed to enhance the genomic selection for groat percentage

Unusual magnetic and transport properties in HoMn6Sn6 kagome magnet
Get PDFWith intricate lattice structures, kagome materials are an excellent platform to study various fascinating topological quantum states. In particular, kagome materials, revealing large responses to external stimuli such as pressure or magnetic field, are subject to special investigation. Here we study the kagome-net HoMn6Sn6 magnet that undergoes paramagnetic to ferrimagnetic transition (below 376 K) and reveals spin-reorientation transition below 200 K. In this compound, we observe the topological Hall effect and substantial contribution of anomalous Hall effect above 100 K. We unveil the pressure effects on magnetic ordering at a low magnetic field from the pressure tunable magnetization measurement. By utilizing high-resolution angle-resolved photoemission spectroscopy, Dirac-like dispersion at the high-symmetry point K is revealed in the vicinity of the Fermi level, which is well supported by the first-principles calculations. Our investigation will pave the way to understanding the magnetotransport and electronic properties of various rare-earth-based kagome magnets.This article is published as Kabir, Firoza, Randall Filippone, Gyanendra Dhakal, Y.

Credit Card is a widely used electronic chip for easy transactions. The main purpose of the report was to show the security measures of transaction by credit cards. The purpose was to give information about credit cards and how they were introduced. The thesis reportcontained the types of card theft with examples and sited the various protocols used for online transactions. The aim of the thesis project was to conclude whether the card security provided by the banks is safe enough.
The thesis report contained information about many online resources as well as liable books. Many news articles were also considered while writing the report for the card theft records.
The thesis report described both the positive and negative aspects of the protocols used for card securities. Result showed that misuse and complicated processes of protocols has led the identity theft to transactions. To conclude, although many security measures are implemented for the secure transactions, credit card fraud activities are happening in a weekly basis
Article and Author Level Measurements
Get PDFArticle and author level measurements have been discussed in this Unit. Author and researcher identifiers are absolutely essential for searching databases in the WWW because a name like D Singh can harbour a number of names such as Dan Singh, Dhan Singh, Dhyan Singh, Darbara Singh, Daulat Singh, Durlabh Singh and more. The ResearcherID.com, launched by Thomson Reuters, is a web-based global registry of authors and researchers that individualises each and every name. Open Researcher and Contributor ID (ORCID) is also a registry that uniquely identifies an author or researcher. Both have been discussed in this Unit. Article Level Metrics (Altmetrics) has been treated in this Unit with the discussion as to how altmetrics can be measured with Altmetric.com and ImpactStory.org. Altmetrics for Online Journals has also been touched. There are a number of academic social networks of which ResearchGate.net, Academia.edu, GetCited.org, etc. have been discussed. Regional journal networks with bibliometric indicators are also in existence. Two networks of this type such as SciELO – Scientific Electronic Library Online, and Redalyc have been dealt with. This Unit discusses in details aspects such as Unique Identifiers for Authors and Researchers; Article Level Metrics (Altmetrics); Academic Social Networks; and Regional Journal Networks with Bibliometric Indicators
A multiphase phase-field study of three-dimensional martensitic twinned microstructures at large strains
Get PDFA thermodynamically consistent multiphase phase-field approach for stress and temperature-induced martensitic phase transformation at the nanoscale and under large strains is developed. A total of N independent order parameters are considered for materials with N variants, where one of the order parameters describes A M transformations and the remaining N-1 independent order parameters describe the transformations between the variants. A non-contradictory gradient energy is used within the free energy of the system to account for the energies of the interfaces. In addition, a non-contradictory kinetic relationships for the rate of the order parameters versus thermodynamic driving forces is suggested. As a result, a system of consistent coupled Ginzburg-Landau equations for the order parameters are derived. The crystallographic solution for twins within twins is presented for the cubic to tetragonal transformations. A 3D complex twins within twins microstructure is simulated using the developed phase-field approach and a large-strain-based nonlinear finite element method. A comparative study between the crystallographic solution and the simulation result is presented.This is a pre-print of the article Basak, Anup, and Valery I. Levitas.

A human-like steering model: Sensitive to uncertainty in the environment
No full textThe interaction between a human driver and an automated driving system may improve when the automation is designed in such a way that it behaves in a human-like manner. This paper introduces a human-like steering model, in which the driver adapts to the risk due to uncertainty in the environment. Current steering models take a risk-neutral approach, while the fields of economics and sensorimotor control suggest that humans exhibit risk-sensitive behavior. The proposed model uses a risk-sensitive optimal feedback control structure to predict steering behavior. The paper studies the effect of the risksensitivity parameter and compares the prediction of the riskneutral and risk-sensitive controllers in a simulated abstraction of two scenarios: (a) driving while being subjected to lateral wind gusts and (b) overtaking an unpredictably swerving car. The simulation results show that the risk-sensitive model adapts to the uncertainty in the environment. Experimental data will be needed to validate the predictions of our model.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Human-Robot InteractionBiomechatronics & Human-Machine Contro
Driver response times to auditory, visual, and tactile take-over requests: A simulator study with 101participants
No full textConditionally automated driving systems may soon be available on the market. Even though these systems exempt drivers from the driving task for extended periods of time, drivers are expected to take back control when the automation issues a so-called take-over request. This study investigated the interaction between take-over request modality and type of non-driving task, regarding the driver's reaction time. It was hypothesized that reaction times are higher when the non-driving task and the take-over request use the same modality. For example, auditory take-over requests were expected to be relatively ineffective in situations in which the driver is making a phone call. 101 participants, divided into three groups, performed one of three non-driving tasks, namely reading (i.e., visual task), calling (auditory task), or watching a video (visual/auditory task). Results showed that auditory and tactile take-over requests yielded overall faster reactions than visual take-over requests. The expected interaction between takeover modality and the dominant modality of the non-driving task was not found. As for self-reported usefulness, auditory and tactile take-over requests yielded higher scores than visual ones. In conclusion, it seems that auditory and tactile stimuli are equally effective as take-over requests, regardless of the non-driving task. Further study into the effects of realistic non-driving tasks is needed to identify which non-driving tasks are detrimental to safety in automated driving.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Biomechatronics & Human-Machine Contro
LPWAN Performance Enhancement for IoT in the Smart Grid
No full textWith the proliferation of IoT devices across the globe, the adoption of IoT related technologies has been increasing rapidly. Newer technologies which fall in the category of Low Power Wide Area Network (LPWAN) have increased this adoption even further. A lot of research is being done in LPWAN licensed band as well as unlicensed band technologies to make them more efficient, such as in terms of power consumption and latency. In this thesis the author has focused on cellular IoT technologies (licensed spectrum LPWAN technologies), to improve the end-to-end behavior. The focus is to see and improve the effect of the device on the network behavior. We have done tests on different networks and went through the 3GPP Specification Release 14 to find possible areas of improvement. Keeping this in mind we have designed a solution to increase the number of pageable devices that can be maintained by the network compared to its original capacity (when not using our solution). This solution can be used to optimize as per the use case, whether to provide lower latency or save energy consumption of the device. To verify that the solution can be used in real life, we have tested it with Stedin critical application device in their substation.Electrical Engineering | Embedded System
