Design studios are where design students spend most of their time learning theory and practices. For this reason, thermal comfort conditions in studios are crucial to provide a suitable environment for education. Especially in the post-pandemic period, thermal comfort conditions have become more critical in educational buildings. The present study focuses on the adaptive thermal comfort condition in an architectural design studio in the Mediterranean climate of Izmir/Turkey. The study aims to evaluate the comfort conditions of the students and determine the effect of mask use on thermal sensation in the post-pandemic period. For this purpose, air temperature, relative humidity, and air velocity measurements were collected during the studio hours in the spring semester when the heating and cooling systems were not working. Additionally, a thermal sensation survey was conducted with 42 students. The results showed that the thermal comfort level was within the 90% acceptability limits according to the ASHRAE Standard-55. According to the survey results, the use of masks by the students did not have a significant effect on thermal perception.

According to the low accuracy of velocity filed in current software, we develop a new system to analyze and visualize the 3D groundwater flow field. We employ the most advanced algorithm to deal with the data form groundwater simulation. The system could compute the flux across arbitrary face and the velocity of arbitrary point in the research domain. The system is debugged in Microsoft Visual Studio. The interactive interface is developed in .Net and the visualization tool is OpenGL. The application shows that the system is robust.

The main goal of this paper is to demonstrate the general characteristics of the educational user-friendly CFD Studio package for CFD teaching. The package was designed for teaching 2D fluid mechanics and heat transfer process, including conduction, coupled conduction/convection, natural and forced convection, external and internal flows, among other phenomena. The finite volume methodology and its related topics can also be taught using the software. Therefore, general aspects of the three main modules, pre-processor, solver and post-processor are discussed aiming to show the generality of the tool. These modules are integrated in the application by a so-called “numerical problem project” which guide the student through the steps to obtain the solution. To approximate the partial differential equations the finite volume approach is employed using a fully-implicit formulation with the interpolation schemes CDS, UDS and WUDS. Mesh editing and nonorthogonal boundary-fitted mesh generation, using algebraic interpolation and elliptic equations, are important features of the package. Coupled heat transfer problems are handled using the “solid-block” formulation and the pressure-velocity coupling uses the SIMPLE and SIMPLEC methods with non-staggered grids. To demonstrate the capabilities two fluid flow and heat transfer “problem projects” are presented.

Pipeline hydraulic transportation is an important method for transporting solid materials. An LBM–DEM-based simulation method is established in the Visual Studio platform using the Fortran language, which can model the hydraulic transportation process of coarse particles in a pipeline. To verify the feasibility of this numerical simulation method, we also conduct pipeline hydraulic transportation experiments and find that the simulation results are consistent with the experimental results. This method is used to investigate the motion characteristics of coarse particles in horizontal pipelines under different conditions because of its advantages of clear physical meaning, ability to deal with complex boundary conditions, and suitability for parallel computing. The results show that the bedload motion is the main motion mode of coarse particles in horizontal pipelines. Changes in the pipeline flow velocity and particle diameter can cause some particles to saltate, and the critical pipeline flow velocity of saltation particles has a linear relationship with the particle diameter. During the process of coarse particles changing from the static state to stable state, the velocity curve of coarse particles gradually changes from “C” type to “S” type with the increase of particle diameter. Moreover, there is a linear relationship between the pipeline flow velocity and the stable velocity of coarse particles, while the particle diameter has no significant influence on the stable velocity. This study provides guidance for the development of pipeline hydraulic transportation technology of coarse particles.

This article presents a non-collision trajectory planning algorithm in three-dimensional space based on velocity potential field for robotic manipulators, which can be applied to collision avoidance among serial industrial robots and obstacles, and path optimization in multi-robot collaborative operation. The algorithm is achieved by planning joint velocities of manipulators based on attractive, repulsive, and tangential velocity of velocity potential field. To avoid oscillating at goal point, a saturated function is suggested to the attractive velocity potential field that slows down to the goal progressively. In repulsive velocity potential field, a spring damping system is designed to eliminate the chattering phenomenon near obstacles. Moreover, a fuzzy logic approach is used to optimize the spring damping coefficients for different velocities of manipulators. Different from the usual tangential velocity perpendicular to the repulsive velocity vector for avoiding the local minima problem, an innovative tangential velocity potential field is introduced that is considering the relative position and moving direction of obstacles for minimum avoidance path in three-dimensional space. In addition, a path priority strategy of collision avoidance is taken into account for better performance and higher efficiency when multi-robots cooperation is scheduled. The improvements for local minima and oscillation are verified by simulations in MATLAB. The adaptabilities of the algorithm in different velocities and priority strategies are demonstrated by simulations of two ABB robots in Robot Studio. The method is further implemented in an experimental platform with a SCARA and an ABB robot cooperation around a stationary obstacle and a moving object, and the result shows real time and effectiveness of the algorithms.

The aqueductal CSF and superior sagittal sinus (SSS) blood flow were quantified in 9 healthy volunteers using a Phase Contrast Cine MR technique with retrospective cardiac gating and velocity of encoding of 10 and 30 cm/s. All subjects were examined in basal conditions, during hypocapnia determined by sustained hyperventilation and during hypercapnia (>5%) obtained with rebreathing in a plastic bag. In basal conditions, the aqueductal CSF flow area showed a mean increase of 24% synchronous with the cerebral systole, whereas variations of the SSS flow area during the cardiac cycle were negligible (>9%). The mean flow velocity and volume in the SSS were 11.7 cm/s and 236 ml/min. Mean peak systolic and diastolic aqueductal CSF velocity were + 2 cm/s and −2 cm/s. Hypocapnia determined in all but one subjects a decrease of the SSS blood and aqueductal CSF velocities. During hypocapnia a decrease of the aqueductal CSF flow area was also observed. Hypercapnia was associated with a decrease of the SSS flow velocity in 3 subjects and to minor changes in the remaining 6 subjects. Hypercapnia determined an increase (up to 30%) in the peak systolic and diastolic aqueductal CSF flow velocity in 3 subjects, negligible changes in 5 subjects and a decrease of the same parameters in one subject. The aqueductal CSF flow area was decreased in 8 subjects during hypercapnia. Hypocapnia and hypercapnia are relatively simple tests which can be used to modify the intracranial hydrodynamic equilibrium in healthy subjects. Further investigations are however needed before their application to the study of intracranial hydrodynamics in patients with hydrocephalus.

We present a new concept of the thermoelectric structure that generates microwave and terahertz signals when illuminated by femtosecond optical pulses. The structure consists of a series array of capacitively coupled thermocouples. The array acts as a hybrid type microwave transmission line with anomalous dispersion and phase velocity higher than the velocity of light. This allows for adding up the responces from all the thermocouples in phase. The array is easily integrable with microstrip transmission lines. Dispersion curves obtained from both the lumped network scheme and numerical simulations are presented. The connection of the thermocouples is a composite right/left-handed transmission line, which can receive terahertz radiation from the transmission line ports. The radiation of the photon to the surface of the thermocouple structure causes a voltage difference with the bandwidth of terahertz. We examined a lossy composite right/left-handed transmission line to extract the circuit elements. The calculated properties of the design are extracted by employing commercial software package CST STUDIO SUITE.

Dead-reckoning via encoders on wheeled-mobile robots is a simple but inaccurate method to estimate position. The major drawback of encoders is wheel slippage errors that accumulate over time. This problem is often addressed by using additional sensors such as compass, gyroscope, or GPS. This paper details the integration and effectiveness of a relatively low-cost solution using an electronic compass to reduce positioning error on a wheeled tricycle mobile robot. A customised Visual Studio program has been developed to adjust the settings of the electronic compass and integrate it with the Visual Studio based robot control system. The electronic compass heading data is fused with the encoder odometry heading data in three different ways: simple fusion, linear weighted fusion, and Kalman filter fusion. Simple fusion and linear weighted fusion rely on parameters determined from angular acceleration and angular velocity, respectively. The Kalman filter uses variance data for the encoders and electronic compass to determine an optimal heading. Experiments have been conducted in an indoor corridor environment to evaluate and compare the various fusion methods. Position error is successfully reduced and is sufficient to locate the robot within the corridor.

Composite structural elements are now used in a variety of components for automotive, aerospace, marine, and architectural structures. The impact resistance of the materials is an important area of research. Fibre reinforced polymer (FRP) structures typically respond poorly to transverse impact events. In addition, uncertainties about the mechanics of damage make it difficult to ascertain the effect of an impact event on the performance of a FRP structure. Compounding these considerations is the fact that, in some cases, the damage will not be visible which could lead to components with considerable damage being allowed to continue in service: a hidden menace. In these series of studies, tests were conducted with an instrumented drop weight impact, an air gun system was developed and a numerical transient analysis conducted on composite plate to understand the loading distribution as a result of impact.

Resumo:
In order to evaluate a biologically relevant measure of exposure, inhalable samplers are designed to match the aspiration efficiency of the human head. Human inhalability is evaluated in wind tunnel studies using mannequins as human surrogates or using numerical and computational methods. There has been differences between human aspiration efficiency estimates using wind tunnel studies and computational fluid dynamics (CFD) modeling, particularly for larger particle sizes (>68 µm). The objective of this dissertation was to evaluate biases in low velocity inhalability studies in an effort to explain the discrepancies in results between experimental and computational inhalability studies. This research addressed the phenomena of secondary aspiration on human facial skin, evaluated the appropriateness of mannequin surfaces as surrogates for humans, and evaluated the performance of the thin-walled reference sampler in low velocities to quantify potential biases in low velocity inhalability studies. The first study determined a realistic coefficient of restitution (CoR) for human facial skin over a range of ages under nine environmental conditions. This study found human facial skin is non-uniform across the face and identified significant interaction between age and sampling location, indicating that how CoR varies with age is dependent on the location sampled. The second study applied the average CoR values for forehead, cheeks and nose in CFD simulations to evaluate the effect of secondary aspiration on human aspiration efficiency estimates and determine how refined the CoR value needed to be to accurately model human aspiration efficiency. This study identified significant increases in aspiration when allowing for particle bounce, but no significant differences between uniform CoRs of 0.5, 0.8 and 1.0, indicating differences between different mannequin surfaces and particle interactions would have minimal effect on aspiration efficiency estimates. The third study evaluated the performance of a horizontally-aligned reference sampler in low wind speeds (0.1 to 0.4 m s-1). While significant differences from unity were identified, differences ranged from -1 to 6% and would have a negligible effect on sampler efficiency estimates. The use of a horizontally-aligned isokinetic reference sampler was found to be appropriate in freestream velocities ranging from 0.1 to 0.4 m s-1.

In this chapter we introduce an important concept concerning the study of both discrete and continuous dynamical systems, the concept of phase space or “state space”. It is an abstract mathematical construction with important applications in statistical mechanics, to represent the time evolution of a dynamical system in geometric shape. This space has as many dimensions as the number of variables needed to define the instantaneous state of the system. For instance, the state of a material point moving on a straight line is defined by its position and velocity at each instant, so that the phase space for this system is a plane in which one axis is the position and the other one the velocity. In this case, the phase space is also called “phase plane”. It is later applied in many chapters of the book.

The chapter begins with a description of the normal findings in healthy sensory and motor nerves. The distribution of nerve fibres by diameter in the sensory nerve and its effect on the recorded action potential is outlined. The method by which velocity and compound muscle action potential are derived from motor stimulation follows. H-reflex studies and F-wave identification are described. A section on the strategies used for nerve conduction study in children and the nerves chosen for examination leads on to a description of the difficulties of deriving normative data in children. Next follows a detailed description of the findings in both sensory and motor nerves in demyelination where a distinction between patchy and homogenous demyelination is possible. An analysis of the nerve findings in axonal degeneration is then presented. The chapter finishes with a discussion of the variability in nerve testing.

AbstractThe entrance of shiplock’s approach channel always exist a mixing shear layer caused by the shear mixing layer, where is the junction of main river flow and the quiescent water of the approach channel. The flow structure of the turbulent mixing area presented as large-scale vortices frequently and periodically. And the fluctuations of the water surface and velocity induced by the separation of vortices may threat the navigation conditions, which should be considered during the engineering designing. The existing studies regard the mixing shear layer as steady flow and only take care of the average shear velocity, which may underestimate the harm of the shear flow. In this work, RNG k-ε model and LES model were adoped to study the hydraulic characteristics of the entrance. The vortex characteristics and the influence on the water level and velocity were analyzed. Results shown that LES model had better precision than RNG k-ε model in the unsteady characteristics. Then further studies about the recirculation flow were performed with LES model, The length and period of the recirculation flow was studied. It found that the vortex was generated at the upstream of shear zone, and then transferred with the recirculate flow until it was collapsed. All the above provide references for hydraulic characteristics of the entrance.

AbstractWhen talking about the Apparent Haptic Motion (AHM) illusion, temporal parameters are the most discussed for providing the smoothest illusion. Nonetheless, it is rare to see studies addressing the impact of changing these parameters for conveying information about the velocity of the elicited motion sensation. In our study, we investigate the discrimination of velocity changes in AHM and the robustness of this perception, considering two stimulating sensations and two directions of motion. Results show that participants were better at discriminating the velocity of the illusory motion when comparing stimulations with higher differences in the actuators activation delay. Results also show limitations for the integration of this approach in everyday life applications.

The Texas A&M water channel experiment is modified to examine the effect of single-mode initial conditions on the development of buoyancy-driven mixing (Rayleigh-Taylor) with small density differences (low-Atwood number). Two separated stratified streams of ∼ 5°C difference are convected and unified at the end of a splitter plate outfitted with a servo-controlled flapper. The top (cold) stream is dyed with Nigrosine and density is measured optically through the Beer-Lambert law. Quantification of the subtle differences between different initial conditions required the optical measurement uncertainties to be significantly reduced. Modifications include a near-uniform backlighting provided through quality, repeatable, professional studio flashes impinging on a white-diffusive surface. Also, a black, absorptive shroud isolates the experiment and the optical path from reflections. Furthermore, only the red channel is used in the Nikon D90 CCD camera where Nigrosine optical scatterring is lower. This new optical setup results in less than 1% uncertainty in density measurements, and 2.5% uncertainty in convective velocity. With the Atwood uncertainty reduced to 4% using a densitometer, the overall mixing height and time uncertainty was reduced to 5% and 3.5%, respectively. Initial single-mode wavelengths of 2, 3, 4, 6, and 8 cm were examined as well as the baseline case where no perturbations were imposed. All non-baseline cases commence with a constant velocity which then slows, eventually approaching the baseline case. Larger wavelengths grow faster, as well as homogenize the flow at a faster rate. The mixing width growth rates were shown to be dependent on initial conditions, slightly outside of experimental uncertainty.

Estuaries trap much of the fine sediment delivered to them by rivers. This phenomenon presents challenges to the US Army Corps of Engineers (USACE) navigation mission, which maintains navigable waterways for waterborne commerce through estuarine regions. The USACE Regional Sediment Management Program and the USACE Norfolk District are conducting a regional sediment transport modeling study to identify cost-effective sediment management schemes in the James River, a tributary estuary of Chesapeake Bay. A key element of the sediment transport modeling study is the definition of cohesive sediment transport processes, such as erosion and settling velocity. This report describes field-based measurements of cohesive sediment erosion and settling velocity conducted in November 2017. The team conducted erosion testing on 15 cores collected throughout the tidal system. Additionally, two anchor stations were occupied to measure tidal variations in vertical distributions of suspended sediment concentration, particle size, and settling velocity. Recommended cohesive sediment transport parameters were developed from the field measurements.

Considerable effort has been put forth to develop an automated method for balancing the power cylinders of reciprocating integral engines used in the natural gas industry. The benefits to power cylinder balance include reducted emissions and improved cylinder component mechanical integrity (which should lead to reductions in repair costs). The current approach to automate engine balancing uses pressure transducers to measure cylinder pressure, then integrate the signals into the engine fuel /timing management controller to achieve engine balance. Each power cylinder must be instrumented, which quickly leads to an expensive installation package. For large units (12 to 16 power cylinders), the likelihood of transducer failure and / or calibration changes will be problematic to reliable operation of this autobalancing system. A potential alternative to multiple transducers measuring power cylinder pressure is to use a single transducer to measure instantaneous shaft rotational velocity. Instantaneous shaft rotational velocity is driven by engine / compressor torque loads, and therefore is sensitive to changes in both power and compressor cylinder operation. This report summarizes the results of an investigation into the possible use of the flywheel rotational velocity as a surrogate for power cylinder pressure measurements in an autobalancing arrangement, or as a balanced/need-to-balance indicator for integral engines. A fundamental model of the rotational kinetics/dynamics was developed and used to predict the flywheel rotational acceleration. The model was validated and enhanced with data acquired as part of this study. The model was then extended to establish a sensitivity matrix, which established the change in predicted torque as a function of power cylinder imbalance. Using the sensitivity matrix, an algorithm was developed to predict the change in power cylinder peak pressures as a function of the change in the measured shaft rotational velocity.

Two-way catalysts or oxidation catalysts are the common after-treatment systems used on lean burn natural gas engines to reduce CO, VOCs and formaldehyde emissions. The study evaluates the performance of oxidation catalysts from commercial vendors for varying catalyst temperature and space velocity. For this study, a part of the exhaust from a Waukesha VGF-18 GL lean burn natural gas engine was flowed through a catalyst slipstream system to assess the performance of the oxidation catalysts. The slipstream is used to reduce the size of the catalysts and to allow precise control of temperature and space velocity. Analyzers used include Rosemount 5-gas emissions bench, Nicolet Fourier Transform Infra-Red spectrometer and HP 5890 Series II Gas Chromatograph. The oxidation catalysts were degreened at 1200oF (650oC) for 24 hours prior to performance testing. The reduction efficencies for the emission species varied among the oxidation catalysts tested from different vendors. Most oxidation catalysts showed over 90% maximum reduction efficiencies on CO, VOCs and formaldehyde. VOC reduction efficiency was limited by poor propane emission reduction efficiency at the catalyst temperatures tested. Saturated hydrocarbons such as propane showed low reduction efficiencies on all oxidation catalysts due to high activation energy. Variation in space velocity showed very little effect on the conversion efficiencies. Most species showed over 90% conversion efficiency during the space velocity sweep. Adding more catalyst volume may not increase the reduction efficiency of emission species. Varying cell density showed very little effect on performance of the oxidation catalysts. The friction factor correlation showed the friction factor for flow through a single channel is inversely proportional to cell density.

Accurate representation of surface roughness in predictive models of aeolian sediment transport and dust emission is required for model accuracy. While past studies have examined roughness effects on drag partitioning, the spatial and temporal variability of surface shear velocity and the shear stress ratio remain poorly described. Here, we use a four-month dataset of total shear velocity (u*) and soil surface shear velocity (us*) measurements to examine the spatiotemporal variability of the shear stress ratio (R) before, during, and after vegetation green-up at a honey mesquite (Prosopis glandulosa Torr.) shrub-invaded grassland in the Chihuahuan Desert, New Mexico, USA. Results show that vegetation green-up, the emergence of leaves, led to increased drag and surface aerodynamic sheltering and a reduction in us* and R magnitude and variability. We found that us* decreased from 20% to 5% of u* as the vegetation form drag and its sheltering effect increased. Similarly, the spatiotemporal variability of R was found to be linked directly to plant phenological phases. We conclude that drag partition schemes should incorporate seasonal vegetation change, via dynamic drag coefficients and/or R, to accurately predict the timing and magnitude of seasonal aeolian sediment fluxes.
