Abstract:
Abstract Valid-time-shifting (VTS) ensembles, either in the form of full ensemble members (VTSM) or ensemble perturbations (VTSP), were investigated as inexpensive means to increase ensemble size in the NCEP Global Forecast System (GFS) hybrid four-dimensional ensemble–variational (4DEnVar) data assimilation system. VTSM is designed to sample timing and/or phase errors, while VTSP can eliminate spurious covariances through temporal smoothing. When applying a shifting time interval (τ = 1, 2, or 3 h), VTSM and VTSP triple the baseline background ensemble size from 80 (ENS80) to 240 (ENS240) in the EnVar variational update, where the overall cost is only increased by 23%–27%, depending on the selected τ. Experiments during a 10-week summer period show the best-performing VTSP with τ = 2 h improves global temperature and wind forecasts out to 5 days over ENS80. This could be attributed to the improved background ensemble distribution, ensemble correlation accuracy, and increased effective rank in the populated background ensemble. VTSM generally degrades global forecasts in the troposphere. Improved global forecasts above 100 hPa by VTSM may benefit from the increased spread that alleviates the underdispersiveness of the original background ensemble at such levels. Both VTSM and VTSP improve tropical cyclone track forecasts over ENS80. Although VTSM and VTSP are much less expensive than directly running a 240-member background ensemble, owing to the improved ensemble covariances, the best-performing VTSP with τ = 1 h performs comparably or only slightly worse than ENS240. The best-performing VTSM with τ = 3 h even shows more accurate track forecasts than ENS240, likely contributed to by its better sampling of timing and/or phase errors for cases with small ensemble track spread.

This briefing note explores the argument that the alleged July 22nd, 2019 attacks on protesters in Hong Kong were perpetrated by a group that can be classified as a Violent Transnational Social Movement (VTSM). When scrutinized, the alleged acts of violence and observed motivations of the United Bamboo triad, plus their transnational and identity-based nature of the operation, suggest that the United Bamboo triad may be a VTSM.

Abstract:
The impact of train architecture and design characteristics on track deterioration accounts for a significant proportion of the whole-life costs of operating a railway. Introducing new train fleets with an expected life in excess of 30 years means that it is important to optimise train design to minimise track deterioration, maximise track life and realise long-term cost savings. Furthermore, higher traffic tonnage (from more frequent services) and increased train acceleration and speeds will cause increasing track deterioration rates; therefore, this issue is central to managing a sustainable railway in future. The track ‘friendliness’ of a train is determined by several ‘vehicle/track interaction’ parameters: train mass, axle load, number of axles, bogie unsprung mass, traction power, suspension ride forces and speed. The Vehicle/Track Interaction Strategic Model (VTISM) can be used to analyse the effect of these parameters on track forces and the resultant track deterioration and maintenance and renewal costs. This paper describes a study undertaken using the VTISM to investigate the impact of axle loads and train architecture on vertical deterioration and costs of ballasted track on a Great Britain railways ‘classic’ mainline route (up to 125 mph) and, following VTISM upgrading and validation, a high-speed route (up to 360 km/h). It identifies where potential cost advantages may be obtained when comparing conventional trains with new, alternative train architectures.

Abstract:
The purpose of this briefing note is to examine the escalation to violence of Violent Transnational Social Movements (VTSM), specifically the Black Hebrew Israelites (BHI). The BHI is a more than 100-year-old group that has arguably been in the political background for the past two decades and appears to have escalated from using soft violence tactics to kinetic violence after the Jersey City Deli Shooting. This briefing note primarily focuses on the BHI and their role as a VTSM that uses soft violence and symbolic power as a means to deliver their message.

Abstract:
This paper investigates a more advanced vertical vehicle–slab track interaction model (VTIM) by considering the discontinuity of track slabs, besides, it can be degenerated to the traditional two-dimensional model conveniently. Moreover, a cyclic calculation method (CCM) is further developed to solve infinite length calculations. On this basis, the proposed dynamic model and CCM are validated by comparing with the more comprehensive three-dimensional train–track model and fixed-point excitation method. Then, from aspects of probability statistics and frequency analysis, an illustrative example is particularly conducted to comprehensively characterize the dynamic responses of vehicle–slab track systems, in which the representative and realistic rail irregularity sets simulated by the track irregularity probabilistic model are used as the loading inputs. Results show that, with a low consumption of computational time and computer memory, the dynamic results derived from VTIM and CCM have a high accuracy, which indicates that the proposed dynamic model and calculation method can be efficiently and accurately used to analyze train–slab track interactions.

Abstract:
The article discusses the relationship between authorities and business in 19211922 using the example of the litigation at the end of March 1922 at the Supreme Tribunal of All-Russian Central Executive Committee (VTsIK) accusing a group of employees of the People’s Commissariat of Foreign Trade, Supreme Economic Council and private intermediaries in the sale and resale of imported paraffin at speculative prices. The uniqueness of this case was that the harsh sentence was quashed by the Presidium of VTsIK, and the case was dismissed. The deal lasted two weeks and was investigated by the Cheka and the Supreme Tribunal by denunciation of one of the customers who was dissatisfied with the growth in paraffin prices during this time. The process went in accordance with Lenin’s directive to combat the abuse of NEP, although the defendants did not break the laws. Investigations and the court attributed normal trading practice to those abuses. It is shown that Lenin’s instruction contradicted the principle of raising the productive forces at all costs previously put forward by himself. The article shows controversy between the leaders of economic departments, who spoke out in defense of the accused and for the development of NEP, and law enforcement officials who tried to limit NEP. The reasons for the cancellation of a severe conviction are analyzed. It is proposed how to use the lessons of the paraffin case to improve present relationships between business and authorities.

Abstract:
In the realm of FPGAs, many tool vendors offer behaviorally-based simulators aimed at easing the complexity of large FPGA designs. At times, a behaviorally-modeled design does not work in hardware as expected or intended. VTsim, a Virtex-II device simulator, was designed to resolve this and many other design problems by providing a window into the FPGA fabric via a virtual device. VTsim is an event-driven device simulator modeled at the CLB level with multiple clock domain support. Utilizing JBits3 and ADB, VTsim enables simulation and examination of all resources within an FPGA via a virtual device. The only input required by VTsim is a bitstream, which can be generated from any tool suite. The simulator is part of the JHDLBits open-source project, and was designed for rapid response, low memory usage, and ease of interaction.

No ambiente universitário, um grande esforço é feito para disponibilizar ferramentas que facilitem aos graduandos, desde o início do curso, a fazer uma correlação entre conteúdos matemáticos abstratos e sua aplicação em uma realidade física, objetivando não apenas a melhor compreensão e fixação de conceitos físicos e matemáticos, mas estimulando o interesse do aluno a estes conceitos. Este trabalho propõe uma ferramenta de simulação de topologias variáveis, que possibilita uma realimentação visual de um sistema descrito através dos dispositivos físicos que o constituem, permitindo ao aluno a interatividade com processo simulado, e uma mais fácil associação com a dinâmica do sistema estudado, pontos-chave na utilização de experimentos para fixação e compreensão de conceitos de controle. Esta ferramenta implementará um algoritmo de simulação em blocos, onde cada bloco é processado individualmente em termos de suas entradas e saídas, proporcionando uma relação direta entre cada aspecto do experimento físico e cada bloco funcional utilizado na simulação. Como os blocos são simulados separadamente, existe também uma relação direta entre as grandezas mensuráveis no experimento físico e as grandezas utilizadas na interligação entre os blocos na simulação.

This work proposes a variable topology simulation tool, which allows a visual feedback of a system described using physical devices, enabling the student to interact with the simulated system, key points in the utilization of experiments for the comprehension and fixation of control concepts. This tool will implement an block simulation algorithm , where each block is processed individually, in terms of its inputs and outputs, providing a direct relantionship between between each aspets of the physical experiment and each functional block used in the simulation. Since the blocks are simulated separately, there is also a direct relantionship between the measurable values on the physical experiment and the values used on the interconnection between blocks on the simulation.

Abstract:
We present the development of a three-dimensional Vehicle/Tire/Terrain Interaction Model (VTTIM) consisting of a general 3D tire-terrain traction model which operates on a novel deformable terrain representation that utilizes a soil compaction model. Rather than utilizing popular empirical terramechanics models that only consider the pressure/sinkage directly under the tire, the governing equations of the terrain are based on i) the propagation of subsoil stresses due to vehicular loads, and ii) the resulting stress/strain which is based on a visco-elastic-plastic soil model developed by Ayers and Bozdech. The implementation of the terrain model is modularized in the form of an API, as the vehicle and tire are assumed to be contained in commercial simulation software as to focus on the implementation of the deformable terrain model. A number of test simulations are run using a rigid tire with and without grousers to show the capability of the VTTIM to predict tire forces for use in vehicle mobility and traction performance simulations. Power and energy required to deform the terrain will also be presented with the simulation results, which allows the prediction of the extra power required by a vehicle traveling on off-road, deformable soil.

Abstract:
<p>The symptoms of overdue maintenance and underinvestment in historic infrastructure are ever-present in our society (rated with D+ by American Society of Civil Engineers, ASCE). To ensure the safety of historic and existing structures, on-site inspections are required, and structural health monitoring systems are frequently adopted. While these methods capture large amounts of information about a structure, there is not a comprehensive method for integrating these diverse datasets into a single, intuitive environment for both on- and off-site usage. The objective of this work is to explore two different methodologies for integrating datasets derived from the built environment. The first method, Virtual tours and informational modeling (VTIM), uses spherical panoramas to capture the interior and exterior of the built environment as well as enables a user to access data through on-click conditionals attached to the panoramas. The second method, Image-based documentation and augmented reality (IBDAR), uses a sparse point cloud to capture the built environment for on-site viewing and additionally stores an image at every annotation location to facilitate off-site viewing. Both methods are applied to case studies including a masonry lighthouse in Charleston, SC and a pedestrian bridge in Princeton, NJ. The advantages and disadvantages of each approach are discussed as well as steps for future work are briefly outlined.</p>
