Abstract:
We present arguments in support of the view that Newton’s first law of motion extends itself to stochastic motions as follows: Every entity perseveres in its state of independent and stationary increments except insofar as it is compelled to change its state by forces impressed. Some of the far-reaching consequences of the extended law are briefly touched upon as well.

Abstract:
Based on the stability and bifurcation theory of dynamical systems, the bifurcation behaviors and chaotic motions of the two-state variable friction law of a rock mass system are investigated by the bifurcation diagrams based on the continuation method and the Poincaré maps. The stick-slip of the rock mass is formulated as an initial values problem for an autonomous system of three coupled nonlinear ordinary differential equations (ODEs) of first order. The results of linear stability analysis indicate that there is an equilibrium position in the rock mass system. Furthermore, numerical results of nonlinear analysis indicate that the equilibrium position loses its stability from a sup-critical Hopf bifurcation point, and then the bifurcating periodic motion evolves into chaotic motion through a series of period-doubling bifurcations with the decreasing of the control parameter. The stick-slip and chaotic motions evolve into infinity in the end with some unstable periodic motions.

Abstract:
The additive monotone (respectively boolean) unitary Brownian motion is a non-commutative stochastic process with monotone (respectively boolean) independent and stationary increments which are distributed according to the arcsine law (respectively Bernoulli law). We introduce the monotone and boolean unitary Brownian motions and derive a closed formula for their associated moments. This provides a description of their spectral measures. We prove that, in the monotone case, the multiplicative analog of the arcsine distribution is absolutely continuous with respect to the Haar measure on the unit circle, whereas in the boolean case the multiplicative analog of the Bernoulli distribution is discrete. Finally, we use quantum stochastic calculus to provide a realization of these processes as the stochastic exponential of the correspending additive Brownian motions.

Abstract:
In this paper, the existence of periodic motions of a discontinuous delayed system with a hyperbolic switching boundary is investigated. From the delay-related [Formula: see text]-function, the crossing, sliding and grazing conditions of a flow to the switching boundary are first developed. For this time-delayed discontinuous dynamical system, there are 17 classes of generic mappings in phase plane and 66 types of local mappings in a delay duration. The generic mappings are determined by subsystems in three domains and two switching boundaries. Periodic motions in such a delay discontinuous system are constructed and predicted analytically from specific mapping structures. Three examples are given for the illustration of periodic motions with or without sliding motion on the switching boundary. This paper shows how to develop switchability conditions of motions at the switching boundary in the time-delayed discontinuous systems and how to construct the specific periodic solutions for the time-delayed discontinuous systems. This study can help us understand complex dynamics in time-delayed discontinuous dynamical systems, and one can use such analysis to control the time-delayed discontinuous dynamical systems.

Abstract:
Platform motions induced by waves pose a challenge to accurately predict the aerodynamic performance of floating offshore wind turbines (FOWTs). In view of this, the power performance and wake structure of FOWTs under platform pitch, surge, and their combined motions were investigated in this paper, using the computational fluid dynamics software, STAR-CCM+, with overset meshing and rigid body motion techniques. First, the simulation cases in single and same-phase combined motions with different amplitudes and frequencies were performed. Afterward, the approach of calculating the phase difference between pitch and surge motions was proposed to investigate the influence of the combined motion with phase difference on the aerodynamic performance. Results show that the increment of amplitude and frequency augments the mean power output and aggravates the power fluctuation in single and same-phase combined motions. The intensity of power variation under combined motion with a phase difference is weakened at 0.1 Hz compared to the single motion, while enhanced at 0.2 Hz, showing a different influence law on the aerodynamic performance. In addition, this paper established the power fluctuation table based on real sea states of Shidao in China, providing a certain reference for the controller design in this sea area.

Solute isotope effects on Henry’s law constants of aqueous solutions of argon atoms, of helium atoms, and of nitrogen molecules are considered. A cell model is employed; the translational and rotational motions are treated in the first quantum approximation while the vibrational motion of nitrogen is fully treated (but assumed to be separable and harmonic). The required mean square forces (or equivalent frequency parameters) are evaluated by classical molecular dynamics calculations.

Abstract:
Closed-form expressions are established for dimensionless long-tome solutions of some mixed initial-boundary value problems. They correspond to three isothermal unsteady motions of a class of incompressible Maxwell fluids with power-law dependence of viscosity on the pressure. The fluid motion, between infinite horizontal parallel flat plates, is induced by the lower plate that applies time-dependent shear stresses to the fluid. As a check of the obtained results, the similar solutions corresponding to the classical incompressible Maxwell fluids performing same motions are recovered as limiting cases of present solutions. Finally, some characteristics of fluid motion as well as the influence of pressure-viscosity coefficient on the fluid motion are graphically presented and discussed.

Abstract:
Following slavery, capital punishment is slowly finding its way toward abolition. This trend is manifested both in international criminal law norms and international human rights norms.
In the international criminal law field, capital punishment, accepted under the Nuremberg and Tokyo Charters, was rejected half a century later in the Statute of the International Tribunal for Former Yugoslavia, then in the Statute of the International Tribunal for Rwanda, and most recently in the Rome Statute.
Parallel to developments in the international criminal law field, a similar evolution was experienced in the area of international human rights. The trend towards abolition in the human rights field began with the restriction of the death penalty application to a certain group of people and crimes. However, a European human rights instrument, Protocol No. 6 to the ECHR, shifted the trend from restriction to abolition of the death penalty.
For the abolitionist cause to succeed, the abolitionist trend should be accepted by retentionist countries such as the US and the Islamic states of the Middle East and Africa. (Abstract shortened by UMI.)

Abstract:
Ensuring the reliability of time estimations is vital for industries, as it establishes the basis for effective planning, resource allocation, and performance assessment, ultimately improving operational efficiency and optimizing workflows. This study, designed to evaluate the accuracy of the MOST predetermined motion time system (PMTS) through comprehensive laboratory experiments, involved twenty participants performing 300 various simple motions. Our focus was on motions characterized by specific features, such as those at higher levels (shoulder height), motions involving objects with varying weights, and motions occurring within the reach distance zone (between 5 cm and 60 cm from the workers). These motion characteristics are often overlooked in MOST data cards. Task durations were initially measured using an accelerometer and then estimated using both the MOST and Fitts' Law (a widely recognized method for estimating the duration of simple motions). The results unveiled a 22% underestimation of MOST estimations by Fitts’ Law. These findings underscore the need to revise MOST data cards for accuracy enhancement and to mitigate potential risks to workers. Future research endeavors should incorporate real-world scenarios and a broader array of motions to further validate and refine these outcomes, ensuring a more comprehensive understanding of the capabilities and limitations of the MOST predetermined motion time system.

Abstract:
Refined theories are employed for accurate predictions of the onset of the parametric instabilities of nonlinearly viscoelastic rings subject to a hydrostatic pressure. The breathing motions are first investigated and closed-form conditions ensuring motions of the hardening or softening type are derived showing that this mode nonlinearity depends on the constitutive law and the static part of the hydrostatic pressure. The parametric instability regions and the ensuing 2-period breathing motions are obtained employing an asymptotic approach. Thereafter, the parametric instabilities of the flexural motions are investigated via a direct asymptotic approach and it is shown that these motions can also be softening or hardening depending on the low-order parts of the constitutive law. The parametric instabilities cause high-amplitude coupled-mode flexural motions involving simultaneously the directly excited mode and its companion mode.

Abstract:
Abstract A scale-invariant statistical theory of fields is presented that leads to invariant definition of density, velocity, temperature, and pressure. The definition of Boltzmann constant is introduced as kk = k = mkvkc = 1.381 × 10−23 J/K, suggesting that Kelvin absolute temperature scale is equivalent to a length scale. Two new state variables called the reversible Qrev = TS and the reversible work Wrev = PV are introduced. The modified forms of the first and second law of thermodynamics are presented. The microscopic definition of heat (work) is presented as the kinetic energy due to random (peculiar) translational, rotational, and pulsational motions. The Gibbs free energy of an element at scale β is identified as the total system energy at scale (β-1), thus leading to an invariant form of the first law of thermodynamics Uβ = Qβ − Wβ + NeβUβ-1.

Full text
Abstract:
Razor clams (Ensis directus) are one of nature’s most adept burrowing organisms, able to dig to 70cm at nearly 1cm/s using only 0.21J/cm. Ensis reduces burrowing drag by using motions of its shell to fluidize a thin layer of substrate around its body. Although these shell motions have an energetic cost, moving through fluidized rather than packed soil results in exponentially lower overall energy consumption. This paper describes the design and testing of RoboClam, a device that mimics Ensis digging methods to understand the limits of razor clam-inspired burrowing, how they scale for different environments and conditions, and how they can be transferred into engineering applications. Using a genetic optimization solver, we found that RoboClam’s most efficient digging motion mimicked Ensis shell kinematics and yielded a power law relationship between digging energy and depth of n = 1.17, very close to the ideal value of n = 1. Pushing through static soil has a theoretical energy-depth power law of n = 2, which means that Ensis-inspired burrowing motions can provide exponentially higher energy efficiency and nearly depth-independent drag resistance.

Abstract:
The effect of aircushion division on the motions of large floating structures is studied by means of calculations based on a linear three-dimensional potential method. A linear adiabatic law is used to describe the air pressures inside the cushions. The water surface within the aircushions and the mean wetted surface are modelled by panel distributions representing oscillating sources. The behaviour of different types of aircushion supported structures is described and compared with that of a rectangular barge having the same dimensions. Successively, the aircushion theory, motion characteristics, wave frequency forces and moments, mean second order drift forces and surrounding wave fields are discussed. The results show that aircushions significantly influence the stability and behaviour of large floating structures.

Abstract:
Theoretical pump head is discussed and the conservation low is introduced on Centrifugal force. Theoretical head obtained by the application of conservation law on fluid flow in rotating flow passage is formed as the difference between the head obtained at the impeller outlet and that at impeller inlet. Conservation low of Centrifugal force due to fluid particles rotational motion at constant angular velocity says that the magnitude of Centrifugal force caused by the rotational motion along the outside circular line is constructed from those caused by the rotational motions along two different kinds circular lines. One is that caused by the rotational motion along the inside circular line whose rotational center locates at the axis of rotation. And the other is that caused by the rotational motion along the circular line whose circular line touches internally with the outer circular line and locates its rotational center on the inside circular line.

Full text
Abstract:
Abstract In order to suppress crane load vibrations on ship vessels, a novel mechanism called a mechanical filter was developed by us recently. This mechanism was implemented on the basis of the premise that by actively and passively controlling the pivot point about which the load oscillates, one can effectively suppress crane load motions. In the present efforts, it is demonstrated that with an aid of a static feedback control law, one can effectively eliminate bifurcations that can lead to large changes in the crane load motions from the window of the considered ranges of disturbance frequency and disturbance amplitude parameters. The response amplitude of the crane load to ship-roll motions is attenuated to a low magnitude over the disturbance parameter window. Variations in the control input with respect to the crane-load mass are also investigated.

Abstract:
This paper presents the controller design and implementation of a high-precision 6-degree-of-freedom (6-DOF) magnetically levitated (maglev) positioner. This high-precision positioning system consists of a novel concentrated-field magnet matrix and a triangular single-moving part that carries three 3-phase permanent-magnet linear-levitation-motor armatures. Since only a single levitated moving part, namely the platen, generates all required fine and coarse motions, this positioning system is reliable and low-cost. Three planar levitation motors based on the Lorentz-force law not only generate the vertical force to levitate the triangular platen but control the platen’s position and orientation in the horizontal plane. All 6-DOF motions are controlled by magnetic forces only. The platen is regarded a pure mass system, and the spring and damping coefficients are neglected except for the vertical directions. Single-input single-output (SISO) digital lead-lag controllers are designed and implemented on a digital signal processor (DSP). This 6-DOF fully magnetically levitated positioner has a total mass of 5.91 kg and currently exhibits a 120 mm × 120 mm travel range. This positioner is highly suitable for semiconductor-manufacturing applications such as wafer steppers. Several experimental motion profiles are presented to demonstrate the maglev stage’s capability of accurately tracking any planar and 3-D paths.

Abstract:
An update to the BCHydro ground-motion model for subduction earthquakes has been developed using the 2018 PEER NGA-SUB dataset. The selected subset includes over 70,000 recordings from 1880 earthquakes. The update modifies the BCHydro model to include regional terms for the VS30 scaling, large distance (linear R) scaling, and constant terms, which is consistent with the regionalization approach used in the NGA-W2 ground-motion models. A total of six regions were considered: Cascadia, Central America, Japan, New Zealand, South America, and Taiwan. Region- independent terms are used for the small-magnitude scaling, geometrical spreading, depth to top of rupture (ZTOR ) scaling, and slab/interface scaling. The break in the magnitude scaling at large magnitudes for slab earthquakes is based on thickness of the slab and is subduction-zone dependent. The magnitude scaling for large magnitudes is constrained based on finite-fault simulations as given in the 2016 BCHydro model. Nonlinear site response is also constrained to be the same as the 2016 BCHydro model. The sparse ground-motion data from Cascadia show a factor of 2–3 lower ground motions than for other regions. Without a sound physical basis for this large reduction, the Cascadia model is adjusted to be consistent with the average from all regions for the center range of the data: M = 6.5, R = 100 km, VS30 = 400 m/sec. Epistemic uncertainty is included using the scaled backbone approach, with high and low models based on the range of average ground motions for the different regions. For the Cascadia region, the ground-motion model is considered applicable to distance up to 1000 km, magnitudes of 5.0 to 9.5, and periods from 0 to 10 sec. The intended use of this update is to provide an improved ground-motion model for consideration for use in the development of updated U.S. national hazard maps. This update ground-motion model will be superseded by the NGA-SUB ground-motion model when they are completed.

Abstract:
Over the past decade, several long-duration subduction earthquakes took place in different locations around the world, e.g., Chile in 2010, Japan in 2011, China in 2008, and Indonesia in 2004. Recent research has revealed that long-duration, large-magnitude earthquakes may occur along the Cascadia subduction zone of the Pacific Northwest Coast of the U.S. The duration of an earthquake often affects the response of structures. Current seismic design specifications mostly use response spectra to identify the hazard and do not consider duration effects. Thus, a comprehensive understanding of the effect of the duration of the ground motion on structural performance and its design implications is an important issue. The goal of this study was to investigate how the duration of an earthquake affects the structural response of special concentric braced frames (SCBFs). A comprehensive experimental program and detailed analytical investigations were conducted to understand and quantify the effect of duration on collapse capacity of SCBFs, with the goal of improving seismic design provisions by incorporating these effects. The experimental program included large-scale shake table tests, and the analytical program consisted of pre-test and post-test phases. The pre-test analysis phase performed a sensitivity analysis that used OpenSees models preliminarily calibrated against previous experimental results for different configuration of SCBFs. A tornado-diagram framework was used to rank the influence of the different modeling parameters, e.g., low-cycle fatigue, on the seismic response of SCBFs under short- and long-duration ground motions. Based on the results obtained from the experimental program, these models were revisited for further calibration and validation in the post-test analysis. The experimental program included three large-scale shake-table tests of identical single-story single-bay SCBF with a chevron-brace configuration tested under different ground motions. Two specimens were tested under a set of spectrally-matched short and long-duration ground motions. The third specimen was tested under another long-duration ground motion. All tests started with a 100% scale of the selected ground motions; testing continued with an ever-increasing ground-motion scale until failure occurred, e.g., until both braces ruptured. The shake table tests showed that the duration of the earthquake may lead to premature seismic failure or lower capacities, supporting the initiative to consider duration effects as part of the seismic design provisions. Identical frames failed at different displacements demands because of the damage accumulation associated with the earthquake duration, with about 40% reduction in the displacement capacity of the two specimens tested under long-duration earthquakes versus the short-duration one. Post-test analysis focused first on calibrating an OpenSees model to capture the experimental behavior of the test specimens. The calibration started by matching the initial stiffness and overall global response. Next, the low-cycle fatigue parameters were fine-tuned to properly capture the experimental local behavior, i.e., brace buckling and rupture. The post-test analysis showed that the input for the low-cycle fatigue models currently available in the literature does not reflect the observed experimental results. New values for the fatigue parameters are suggested herein based on the results of the three shake-table tests. The calibrated model was then used to conduct incremental dynamic analysis (IDA) using 44 pairs of spectrally-matched short- and long-duration ground motions. To compare the effect of the duration of ground motion, this analysis aimed at incorporating ground-motion variability for more generalized observations and developing collapse fragility curves using different intensity measures (IMs). The difference in the median fragility was found to be 45% in the drift capacity at failure and about 10% in the spectral acceleration (Sa). Using regression analysis, the obtained drift capacity from analysis was found to be reduced by about 8% on average for every additional 10 sec in the duration of the ground motion. The last stage of this study extended the calibrated model to SCBF archetype buildings to study the effect of the duration of ground motion on full-sized structures. Two buildings were studied: a three-story and nine-story build that resembled the original SAC buildings but were modified with SCBFs as lateral support system instead of moment resisting frames. Two planer frames were adopted from the two buildings and used for the analysis. The same 44 spectrally-matched pairs previously used in post-test analysis were used to conduct nonlinear time history analysis and study the effect of duration. All the ground motions were scaled to two hazard levels for the deterministic time history analysis: 10% exceedance in 50 years and 2% exceedance in 50 years. All analysis results were interpreted in a comparative way to isolate the effect of duration, which was the main variable in the ground-motion pairs. In general, the results showed that the analyzed SCBFs experienced higher drift values under the long-duration suite of ground motions, and, in turn, a larger percentage of fractured braces under long-duration cases. The archetype SCBFs analysis provided similar conclusions on duration effects as the experimental and numerical results on the single-story single-bay frame.

Abstract:
Every day, overweight and excessively heavy vehicles cause damage to roads, bridges, and other vehicle-based infrastructure. To protect the vital transportation infrastructure for the U.S., states have imposed weight limits for commercial and fleet transport vehicles. A common way for enforcing these weight limits is to guide trucks off the road to weigh stations where the vehicles can be weighed using static truck scales. A disadvantage of these dedicated weigh stations is that they take up a substantial amount of space (which is not always available) and time to conduct weighments, as well as cause delays to traffic flow that may impede commerce based on truck transport. A solution to these problems is the use of high-speed weigh-in-motion (WIM) systems that are installed in the road and weigh vehicles as they pass by while maintaining their speed. For jurisdictions to effectively use a WIM system for direct enforcement of weight limits, the system must be evaluated against a recognized standard to establish suitability for its intended application. The vast majority of weighing instruments used for legal metrology purposes (including law enforcement) need to comply with the requirements in NIST Handbook 44 Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices. However, the NIST Handbook 44 does not (yet) cover WIM systems for direct enforcement. Although state and local jurisdictions use NIST Handbook 44 to certify legal metrological instruments, it does not exclude jurisdictions from using additional technical standards to certify certain instruments. New York City recently certified a WIM system to protect a critical section of the Brooklyn-Queens Expressway (BQE) by designating it as a pilot project while efforts were made to amend NIST Handbook 44 to include WIM systems for direct enforcement. This publication discusses the main characteristics of WIM systems and how they can be used for direct enforcement. An overview of several alternative documentary standards that can be applied for certification of WIM systems is also provided, with further explanation regarding how the New York City Department of Transportation (NYCDOT) implemented the certification of the WIM system to begin issuing citations to overweight vehicles in an effort to protect the BQE.

Abstract:
Los motivos económicos están entre los factores explicativos básicos de las migraciones, tanto de las internacionales como de las interiores dentro de los países. A su vez, los movimientos migratorios tienen efectos en la economía; en el crecimiento económico en general y también en los distintos mercados (trabajo, vivienda, bienes de consumo, etc.) y los servicios públicos (educación, sanidad, servicios sociales, etc.) El propósito de este documento reside en ofrecer una visión sinóptica de estas interacciones entre migraciones y economía para el caso de las Islas Canarias. Para ello se plantearán inicialmente algunas aclaraciones conceptuales sobre la determinación mutua de ambos procesos, para luego especificarlas con evidencia sobre el caso canario en los principales temas a tener en cuenta: los motivos económicos de las migraciones, su impacto en el crecimiento económico, el mercado de trabajo y las condiciones de vida de la población inmigrante. El apartado final alude a la importancia del marco institucional que regula estas relaciones entre migraciones y economía, ya que están lejos de poder interpretarse como una relación mecánica y alejada de la esfera política.
