Résumé :

<em>Conventional methods for implementing logic programming applications on embedded systems are software- based, requiring a compiler to convert the initial declarative logic program to its equivalent procedural one. This increases the complexity of the final implementation and reduces system performance. However, hardware implementations that only support logic programs prevent their use in applications where logic programs need to be intertwined with traditional procedural ones. This paper exploits HW/SW codesign methods to present a microprocessor capable of supporting hybrid ap- plication

Résumé :

We show that skill requirements in job vacancy postings differentially increased in MSAs that were hit hard by the Great Recession, relative to less hard-hit areas. These increases persist through at least the end of 2015 and are correlated with increases in capital investments, both at the MSA and firm levels. We also find that effects are most pronounced in routine-cognitive occupations, which exhibit relative wage growth as well. We argue that this evidence is consistent with the restructuring of production toward routine-biased technologies and the more-skilled workers that complement them

Résumé :

Tidal stream turbines fixed on the seabed can harness the power of tides at locations where the bathymetry and/or coastal geography result in high kinetic energy levels of the flood and/or neap currents. In large turbine arrays, however, avoiding interactions between upstream turbine wakes and downstream turbine rotors may be hard or impossible, and, therefore, tidal array layouts have to be designed to minimize the power losses caused by these interactions. For the first time, using Navier-Stokes computational fluid dynamics simulations which model the turbines with generalized actuator disks

Résumé :

Custom silicon offers an untapped opportunity for addressing complex challenges in robotics by providing optimized performance and energy efficiency. RISC-V—a novel, open- source Instruction Set Architecture (ISA)—has been gaining rapid traction due to its flexibility and customizability. In this work, we explore the capabilities of RISC-V in the robotics do- main by implementing a complete localization and motion control solution on an FPGA. Leveraging the reconfigurability of FPGAs alongside the extensibility of a custom five-stage pipelined RISC- V processor, our approach demonstrates signi

Résumé :

The wake dynamics of a wind turbine are influenced by the atmospheric turbulence and the wake of its upwind turbine. In this work, we investigate the wake characteristics of a waked wind turbine for four different downwind spacings and three different inflows using large-eddy simulation with a turbine parameterized using the actuator surface model. The wake statistics of the waked turbine are compared with those of the stand-alone wind turbine under the same inflow. The results show that the oncoming wake significantly affects the near wake of the waked turbine, where it accelerates the wake r

This paper focuses on the dynamic internal flow in the integrated aggressive intermediate turbine duct (AITD) with different HPT wake numbers, using CFX Solver with dynamic Reynolds-averaged Navier–Stokes equations (RANS), the shear stress transmission κ-ω turbulence model (SST) and the γ-θ transition model. The HPT wakes are simulated using sweeping rods, with the number of rods ranging from 14 to 56 and a reduced frequency of 1.07. The increasing wake number reduces the radial pressure gradient in the integrated AITD, and then decelerates the radial migration and dissipation of wake vortices

Abstract The US has run a persistent current account deficit since 1982. Its growth particularly accelerated in the early 2000s, and the deficit peaked at about 6% of US GDP in 2006.

This article argues that the concomitant processes of persistent current account deficits, rising inequality, and deepening financialization are not merely coincidental but can be traced to common causes arising from the global restructuring of US production th

An attempt is made to consider the vocal-performing work of the People’s Artist of Ukraine Tetiana Vierkina in the aspect of the “actual intoning” concept, which was developed in her PhD thesis. “Actual intoning” is interpreted by the researcher not only as the performer’s work, who turned the author’s text into the sound reality, into a living speech utterance, but also as the desire to fill her interpretation with relevant meanings that are significant for the modern era. The scientific work by T. Vierkina, devoted to the problems of in

Résumé :

In the last two and a half centuries, industrialization, propelled by a catalytic impact of free-market capitalism, has been contributing to prosperity and breaking the limits beyond all imagination that during the history inhibited the development of human potential. Unfortunately, neoliberal capitalism, as the last and most extreme variant of free-market capitalism, has shown some hidden fractures. After the Great Recession of 2008, the problems due to inbuilt fault lines and misconceptions erupted to the surface. Over the last two years, marked by the COVID-19 pandemic, the world economy ha

Résumé :

The exploration of new acceleration mechanisms for compactly delivering high-energy particle beams has gained great attention in recent years. One alternative that has attracted particular interest is the plasma-based wakefield accelerator, which is capable of sustaining accelerating fields that are more than three orders of magnitude larger than those of conventional radio-frequency accelerators. In this device, acceleration is generated by plasma waves that propagate at nearly light speed, driven by intense lasers or charged particle beams. Here, we report on the direct visualization of the

The rapid and undulating spread of the new dangerous COVID-19 infection across the world has exacerbated many socio-economic problems, showing the precariousness and vulnerability of modern civilization. The labor market was particularly hard hit under the current conditions, as it had been undergoing a gradual structural transformation in the previous period due to the digitalization of the economy, and was now forced to adapt at an accelerated pace to changes in the external environment under the influence of the pandemic and the response of the government to it.

Texte intégral

Résumé :

Recent advances in urban air mobility have driven the development of many new vertical take-off and landing (VTOL) concepts. These vehicles often feature original designs departing from the conventional helicopter configuration. Due to their novelty, the characteristics of the supervortices forming in the wake of such aircraft are unknown. However, these vortices may endanger any other vehicle evolving in their close proximity, owing to potentially large induced velocities. Therefore, improved knowledge about the wakes of VTOL vehicles is needed to guarantee safe urban air mobility operations.

Résumé :

AbstractDepression is characterized by reduced physical activity and sleep-wake cycle disturbances, often considered important features of the disease. While a few studies have suggested that self-reported reduced physical activity and sleep-wake cycle disturbances might both be linked to depression vulnerability, actigraphy-based measures in vulnerable samples remain largely unexplored. This study relied on actigraphy-based parameters to test whether these disturbances characterize depression vulnerability. Seven-day actigraphy data were collected from 20 (13 female) university students with

AbstractPolysomnography (PSG) is the current gold standard in high-resolution sleep monitoring; however, this method is obtrusive, expensive, and time-consuming. Conversely, commercially available wrist monitors such as ActiWatch can monitor sleep for multiple days and at low cost, but often overestimate sleep and cannot differentiate between sleep stages, such as rapid eye movement (REM) and non-REM. Wireless wearable sensors are a promising alternative for their portability and access to high-resolution data for customizable analytics. We present a multimodal sensor system measuring hand acc

In the case of a single-digit picosecond bunch length, synchrotron light sources produce intense coherent radiation up to the THz range. The reduction of the bunch length by lowering the momentum compaction factor (low-α) gives rise to the microbunching instability, which is on the one hand a crucial roadblock in the x-ray range during to the resulting effective bunch lengthening, but on the other hand also an opportunity for the generation of intense THz radiation if it can be controlled appropriately.

Texte intégral

Résumé :

Many traditional ship–rotorcraft interactional simulation approaches, including those used for pilot training, use a one-way coupling between aerodynamics and flight dynamics. In a one-way coupled method, the standalone ship airwake is superimposed on the rotor, modifying its inflow. However, because the rotor wake does not alter the ship airwake and is unaffected by the ship landing deck or superstructure, one-way coupling may not capture all relevant phenomena. To capture important interactional aerodynamic phenomena such as dynamic ground and wall effects, two-way fully coupled simulations

In this study, we experimentally examine the behaviour of a free-falling rigid sphere penetrating a quiescent liquid pool. Observations of the sphere trajectory in time are made using two orthogonally placed high-speed cameras, yielding the velocity and acceleration vectors through repeated differentiation of the time-resolved trajectories. The novelty of this study is twofold. On the one hand, a methodology is introduced by which the instantaneous forces acting on the sphere can be derived by tracking the sphere trajectory. To do this, we work in a natural coordinate system aligned with the p

Large eddy simulation calculations are conducted for flow in a channel with dimples and protrusions on opposite walls with both surfaces heated at three Reynolds numbers, ReH=220, 940, and 9300, ranging from laminar, weakly turbulent, to fully turbulent, respectively. Turbulence generated by the separated shear layer in the dimple and along the downstream rim of the dimple is primarily responsible for heat transfer augmentation on the dimple surface. On the other hand, augmentation on the protrusion surface is mostly driven by flow impingement and flow acceleration between protrusions, while t

In the standard model of solar flares, a magnetic flux rope erupts and gets ejected from the Sun. The current sheets that form in its wake are the seat of magnetic reconnection, which is thought to power energy release throughout the long-lasting decay phase of the thermal X-ray emission. This model has been broadly tested with plasma diagnostics at soft X-ray, EUV, and Hα wavelengths. The primary aim of the present investigation is to shed light on the acceleration of non-thermal electrons in the post-impulsive phase through hard X-ray (HXR) radiation and radio spectroscopic imaging at decime

Abstract To reduce the engine's length and weight, the concept of integrated intermediate turbine duct (IITD) is proposed, in which the first row of the low-pressure turbine vanes are replaced by the turning struts in ITD. The effects of the casing profile on the flow features and loss mechanism in the IITD are investigated by experimental, numerical and theoretical methods. In the baseline case, the casing passage vortex at the exit of the IITD is featured with two branches, which is caused by the entrainment effect of the suction side leg of horseshoe vortex near casing.

A flat-plate turbulent boundary layer (TBL) is experimentally subjected to a family of 22 favourable–adverse pressure gradients (FAPGs) using a ceiling panel of variable convex curvature. We define FAPGs as a sequence of streamwise pressure gradients in the order of favourable followed by adverse, similar in sequence to the pressure gradients over the suction side of an airfoil. For the strongest pressure gradient case, the acceleration parameter, $K$ , varied spatially from $6 \times 10^{-6}$ to $- 4.8 \times 10^{-6}$ .
