 Thermal Performance and Reliability Analysis of a Medium-Voltage Three-Phase Inverter Considering the Influence of High on Parasitic Filter Elements Publication
IDIEEE:8895744Published Date2020-03-01JournalIEEE Journal of Emerging and Selected Topics in Power Electronics, 2020-03-01, Volume 8
In recent years, the use of silicon carbide (SiC) power semiconductor devices in medium-voltage (MV) applications has been made possible due to the development of high blocking voltage (10–15 kV)-based devices. While the use of these devices brings in a lot of advantages, the semiconductor devices are exposed to high peak stress (of up to 15 kV) and a very high $dv/dt$ (of up to 100 kV/ $\mu \text{s}$ ). The high $dv/dt$ across the devices leads to a high $dv/dt$ across other components conne…
 Sleep-Related Practices, Behaviors, and Sleep-Related Difficulties in Deployed Active-Duty Service Members Performing Security Duties. Publication
ID30764663Published Date2020-03-01JournalBehavioral sleep medicine, 2020-03-01, Volume 18
: To assess sleep-related difficulties (e.g., trouble staying asleep, oversleeping, falling asleep while on duty, disturbing dreams, sleep paralysis) and behavioral patterns of active-duty service members (ADSMs) performing security duties. : The participants were 1,169 ADSMs (20-44 years of age). : ADSMs completed an online survey (67.3% response rate) with items assessing demographics, the occupational environment, sleep-related attributes, habits, or difficulties, factors affecting sleep, …
 Limitations of the UNAIDS 90-90-90 metrics: a simulation-based comparison of cross-sectional and longitudinal metrics for the HIV care continuum. Publication
ID32044844Published Date2020-02-10JournalAIDS (London, England), 2020-02-10
The UNAIDS 90-90-90 and other cross-sectional metrics can lead to potentially counterintuitive conclusions when used to evaluate health systems' performance. This study demonstrates how time and population dynamics impact UNAIDS 90-90-90 metrics in comparison with a longitudinal analogue.A simplified simulation representing a hypothetical population was used to estimate and compare inference from UNAIDS 90-90-90 metrics and a longitudinal metrics based on Kaplan-Meier-estimated 2-year probabi…
 Comparing National Approaches to the Study of Intelligence Publication
IDDOI:10.1093/isp/ekz031Published Date2020-02-03JournalInternational Studies Perspectives, 2020-02-03
Abstract This forum compares and contrasts national experiences in the development of intelligence studies from the perspective of seven countries: France, Japan, Israel, Romania, Spain, the United Kingdom, and the United States. The discussion is structured around a comparative framework that emphasizes five core dimensions that, we posit, are essential to the emergence of this subfield: access to relevant government information, institutionalization of research on intelligence and security …
 Analysis on Boolean Function in a Restricted (Biased) Domain Publication
IDIEEE:8786261Published Date2020-02-01JournalIEEE Transactions on Information Theory, 2020-02-01, Volume 66
Boolean functions are usually studied under the assumption that each input bit is considered independent and identically distributed. However, in the case of some stream ciphers, a keystream bit is generated by using a nonlinear Boolean function with inputs from a restricted domain. At Eurocrypt 2016, one such stream cipher (FLIP) has been proposed, where a Boolean function on $n$ variables was exploited with inputs of weight $\frac {n}{2}$ only. Recently, Carlet et al. studied several proper…
 Organizational perspectives on the maneuver warfare movement in the United States Marine Corps: insights from the work of James G. March Publication
IDDOI:10.1093/icc/dtz063Published Date2020-02-01JournalIndustrial and Corporate Change, 2020-02-01, Volume 29
Abstract This article describes a key period in the institutional and organizational history of the United States Marine Corps. Using historical, archival, and interview material, we apply some of the ideas and perspectives of James G. March to understand the organizational dynamics and mechanisms that enabled the maneuver warfare movement and made the modern Marine Corps a more innovative and adaptive organization. We build on and integrate several streams of March’s research, legacies, and …
 Modeling of Energy Demand and Savings Associated with the Use of Epoxy-Phase Change Material Formulations. Publication
ID32023972Published Date2020-01-31JournalMaterials (Basel, Switzerland), 2020-01-31, Volume 13
This manuscript integrates the experimental findings of recently developed epoxy-phase change material (PCM) formulations with modeling efforts aimed to determine the energy demands and savings derived from their use. The basic PCM system employed was composed of an epoxy resin, a thickening agent, and nonadecane, where the latter was the hydrocarbon undergoing the phase transformation. Carbon nanofibers (CNF) and boron nitride (BN) particulates were used as heat flow enhancers. The thermal c…
 A Complete Formula of Ocean Surface Absolute Geostrophic Current. Publication
ID31996755Published Date2020-01-29JournalScientific reports, 2020-01-29, Volume 10
Absolute geostrophic current at the ocean surface (S) contains three components: (1) absolute geostrophic current at the geoid undulation (N), (2) geostrophic shear (between S and N) due to horizontal gradient of dynamic ocean topography, and (3) geostrophic shear (between S and N) due to horizontal gradient of density. However, only the second component is used to represent the surface absolute geostrophic current in physical oceanography and satellite geodesy. Four public datasets are used …
 The Community Code Verification Exercise for Simulating Sequences of Earthquakes and Aseismic Slip (SEAS) Publication
IDDOI:10.1785/0220190248Published Date2020-01-29JournalSeismological Research Letters, 2020-01-29
Abstract Numerical simulations of sequences of earthquakes and aseismic slip (SEAS) have made great progress over past decades to address important questions in earthquake physics. However, significant challenges in SEAS modeling remain in resolving multiscale interactions between earthquake nucleation, dynamic rupture, and aseismic slip, and understanding physical factors controlling observables such as seismicity and ground deformation. The increasing complexity of SEAS modeling calls for e…
 Fast computation of time-domain scattering by an inhomogeneous stratified seafloor. Publication
ID32006962Published Date2020-01-01JournalThe Journal of the Acoustical Society of America, 2020-01-01, Volume 147
Marine sediment properties exhibit fluctuations on a very wide range of scales in all three spatial dimensions. These fluctuations lead to scattering of acoustic waves. Seabed scattering models that treat such fluctuations are reasonably well developed under the plane-wave assumption. A recent model, called TDSS (time domain model for seafloor scattering), accurately treats the important point-source-point-receiver geometry for generally stratified fluid sediments-important because this is th…
