Daylight Distribution Improvement Using Automated Prismatic Louvre

Louvre is a common type of shading devices and has been increasingly used in office buildings. Meanwhile, some reflective types of louvre have been used to provide shade and to redirect daylight deep into buildings interior simultaneously. Furthermore, daylighting systems have been recently engaged with automation control to improve their performance and increase their accuracy. Accordingly, automation of a louvre can optimise daylighting performance, maximising visual comfort, and lighting energy saving. In order to maximise the benefits of daylight, these shading devices should be controlled efficiently using advanced control methods. On the other hand, one of the significant application in daylighting systems is the prismatic panel, which was used in several buildings to improve daylighting due to its easy installation, which also based on redirecting the light into the interior of the buildings, besides its reflective and refractive characteristic. This article presents a feasibility study on the combination of two advanced daylighting designs, i.e., prismatic panel and automated louvre, aiming to achieve simultaneous shading and redirecting daylight for better daylight distribution. In the proposed design, the louvre is comprised of prismatic slats, i.e., prismatic panel as slat. The prismatic louvre is implemented virtually based on an algorithmic system using parametric software Grasshopper, in order to control the automation process parametrically as a first step, and then the daylighting performance is simulated using Radiance as a plug-in to Grasshopper. The optical characteristics of the prismatic slats in an automated louvre is investigated. A comparison has been made in simulation between a prismatic panel and the automated louvres with reflective slats and prismatic slats, respectively, to evaluate their daylighting performance in a south-orientated virtual room in New Cairo. The simulation results are given for the conditions of clear sky on the 21st of June, 21st of September, and 21st of December. © 2020 The Author(s). Published by solarlits.com.

E-DATA: A Comprehensive Field Campaign to Investigate Evaporation Enhanced by Advection in the Hyper-Arid Altiplano

In the endorheic basins of the Altiplano, water is crucial for sustaining unique ecological habitats. Here, the wetlands act as highly localized evaporative environments, and little is known about the processes that control evaporation. Understanding evaporation in the Altiplano is challenging because these environments are immersed in a complex topography surrounded by desert and are affected by atmospheric circulations at various spatial scales. Also, these environments may be subject to evaporation enhancement events as the result of dry air advection. To better characterize evaporation processes in the Altiplano, the novel Evaporation caused by Dry Air Transport over the Atacama Desert (E-DATA) field campaign was designed and tested at the Salar del Huasco, Chile. The E-DATA combines surface and airborne measurements to understand the evaporation dynamics over heterogeneous surfaces, with the main emphasis on the open water evaporation. The weather and research forecasting model was used for planning the instruments installation strategy to understand how large-scale air flow affects evaporation. Instrumentation deployed included: meteorological stations, eddy covariance systems, scintillometers, radiosondes and an unmanned aerial vehicle, and fiber-optic distributed temperature sensing. Additional water quality and CO2 fluxes measurements were carried out to identify the link between meteorological conditions and the biochemical dynamics of Salar del Huasco. Our first results show that, in the study site, evaporation is driven by processes occurring at multiple spatial and temporal scales and that, even in the case of available water and energy, evaporation is triggered by mechanical turbulence induced by wind.
Minimax isometry method: A compressive sensing approach for Matsubara summation in many-body perturbation theory

We present a compressive sensing approach for the long-standing problem of Matsubara summation in many-body perturbation theory. By constructing low-dimensional, almost isometric subspaces of the Hilbert space we obtain optimum imaginary time and frequency grids that allow for extreme data compression of fermionic and bosonic functions in a broad temperature regime. The method is applied to the random phase and self-consistent $GW$ approximation of the grand potential. Integration and transformation errors are investigated for Si and ${\mathrm{SrVO}}_{3}$.
How can political liberalism respond to contemporary populism?

Populism – which positions a ‘true people’ in opposition to a corrupt elite – is often contrasted with liberalism. This article initially outlines the incompatibility between populism and normative theories of political liberalism. It argues that populism is an unreasonable form of politics by liberals’ standards because: it unfairly excludes those who are not deemed to be part of the true ‘people’; and it is objectionably anti-pluralist in the way that it assumes unity amongst the ‘people’. Despite this, it is hard to derive specific duties to contain or challenge populism per se from a liberal perspective, though such a duty might be present for some forms of contemporary right-wing populism that combine populism with illiberal goals. Underpinning this view is a belief that many populist movements articulate grievances that are at least somewhat legitimate. The article concludes by arguing that there might be circumstances where a populist movement could, against this backdrop of injustice, advance the liberal cause. However, this is not because there are ways of dissolving the tension between political liberalism and populism, but because political liberals might be justified in violating the regulatory norms that they believe ought to govern politics in some, exceptional, circumstances.
Pollen germination capacity of three mango cultivars (Mangifera indica L., Anacardiaceae) from Pakistan.

Pollen germination capacity and viability of 3-mango cultivars viz., Chaunsa, Dasheri and Langra were investigated up to 48 weeks. Pollen germination was standard by hanging drop technique in different concentration of sucrose solutions (5%-50%) with 1% agar and 0.001% boric acid. The stored conditions were refrigerator (4oC), freezer (-20oC, -30oC), freeze drier (-60oC), in vacuum over silica gel and in organic solvents (acetone, benzene, chloroform). Pollen stored at low temperature showed better germination percentage compared to pollen stored at 4oC and fresh. Among three cultivars variety langra showed better pollen germination at all stored conditions except at -20oC. Variety chaunsa and dasheri also showed good germination of pollen.
Driving mechanisms of organic carbon burial in the Early Cretaceous South Atlantic Cape Basin (DSDP Site 361)

Abstract. Extensive black shale deposits formed in the Early Cretaceous South Atlantic, supporting the notion that this emerging ocean basin was a globally important site of organic carbon burial. The magnitude of organic carbon burial in marine basins is known to be controlled by various tectonic, oceanographic, hydrological, and climatic processes acting on different temporal and spatial scales, the nature and relative importance of which are poorly understood for the young South Atlantic. Here we present new bulk and molecular geochemical data from an Aptian–Albian sediment record recovered from the deep Cape Basin at Deep Sea Drilling Project (DSDP) Site 361, which we combine with general circulation model results to identify driving mechanisms of organic carbon burial. A multimillion-year decrease (i.e., Early Aptian–Albian) in organic carbon burial, reflected in a lithological succession of black shale, gray shale, and red beds, was caused by increasing bottom water oxygenation due to abating hydrographic restriction via South Atlantic–Southern Ocean gateways. These results emphasize basin evolution and ocean gateway development as a decisive primary control on enhanced organic carbon preservation in the Cape Basin at geological timescales (> 1 Myr). The Early Aptian black shale sequence comprises alternations of shales with high (> 6 %) and relatively low (∼ 3.5 %) organic carbon content of marine sources, the former being deposited during the global Oceanic Anoxic Event (OAE) 1a, as well as during repetitive intervals before and after OAE 1a. In all cases, these short-term intervals of enhanced organic carbon burial coincided with strong influxes of sediments derived from the proximal African continent, indicating closely coupled climate–land–ocean interactions. Supported by our model results, we show that fluctuations in weathering-derived nutrient input from the southern African continent, linked to changes in orbitally driven humidity and aridity, were the underlying drivers of repetitive episodes of enhanced organic carbon burial in the deep Cape Basin. These results suggest that deep marine environments of emerging ocean basins responded sensitively and directly to short-term fluctuations in riverine nutrient fluxes. We explain this relationship using the lack of wide and mature continental shelf seas that could have acted as a barrier or filter for nutrient transfer from the continent into the deep ocean.

False positive reduction of vasculature for pulmonary nodule detection

Lung cancer stands as the deadliest cancer worldwide, and early detection of pulmonary nodules is the focus of many studies to enhance the survival rate. As with many diseases, deep learning is becoming a commonly used technique for computer-aided diagnosis (CAD) in detecting lung nodules. Most lung CAD systems rely on a detection module followed by a false positive (FP) reduction module (FPR); however, FPR removes FPs as well as true positives (TPs). Thus, as a tradeoff, in order to retain high sensitivity, a large number of FPs remain. In our experience, small pulmonary vessels have been the primary source of FPs. Hence, we propose an additional module cascaded on normal FPR module to specifically reduce the number of FPs due to pulmonary vessel. Utilizing a 3D deep learning architecture, we find that the inclusion of various fields of view (FOVs) improves the accuracy of the chosen model. We explore the impact of the selection of the FOVs, the method used to integrate the features from each FOV, and using the FOV as a data augmentation method. We show that this vessel specific FPR module significantly improves the CAD system’s FP rate while only sacrificing 5% of the previously achieved sensitivity.
Color and Animation Preferences for a Light Band eHMI in Interactions Between Automated Vehicles and Pedestrians

In this paper, we report user preferences regarding color and animation patterns to support the interaction between Automated Vehicles (AVs) and pedestrians through an external Human-Machine-Interface (eHMI). Existing concepts of eHMI differ -- among other things -- in their use of colors or animations to express an AV's yielding intention. In the absence of empirical research, there is a knowledge gap regarding which color and animation leads to highest usability and preferences in traffic negotiation situations. We conducted an online survey (N=400) to investigate the comprehensibility of a light band eHMI with a combination of 5 color and 3 animation patterns for a yielding AV. Results show that cyan is considered a neutral color for communicating a yielding intention. Additionally, a uniformly flashing or pulsing animation is preferred compared to any pattern that animates sideways. These insights can contribute in the future design and standardization of eHMIs.
Vegetative Propagation of Asparagus from Lateral Buds

Procedures of vegetative propagation of asparagus were studied using lateral bud culture. Lateral buds excised from a spear were placed on the Murashige and Skoog's medium, the basic medium used in this study, with or without NAA. Shoots that were grown on this medium were used for further vegetative propagation. Mature buds on the proximal part of the shoot were placed on the basic medium and good shoot growth resulted. Apical and young buds on the distal part of shoots were planted on the basic medium containing NAA and kinetin. Shoot and root growth resulted. Plantlets with shoots and roots were transplanted to the basic medium in 500 ml flasks and grew to transplantable size. A comparison of 1, 20 and 50 bud densities/50 ml of medium indicated that there was a growth-promoting diffusing-substance evident by the marked improvement of shoot and root growth at the highest bud density. It was determined that this growth promoting effect was not caused by NAA. Horizontal placing of shoot with bud upright on the medium was more effective for shoot and root growth than either shoots implanted with distal end up or with proximal end up.
Mechanical behavior of self‐stressing steel slag aggregate concrete filled steel tubular stub columns

The mechanical behaviors of the self‐stressing steel slag aggregate concrete filled steel tubular (SSSACFST) stub column are investigated for practical structural applications. Twelve specimens under axial and eccentric compression are tested. The influences of different parameters, such as the eccentricity, the diameter–thickness ratio of the steel tube and the expansion rate of the steel slag aggregate concrete (SSAC) are studied. The experimental results show that the shear and the bending deformation dominate the failures of the specimens under axial and eccentric compression, respectively. The column with a high diameter–thickness ratio has a low ultimate bearing capacity and ultimate strain. The incremental range of the load capacity and the ultimate axial and circumferential strains of the specimens will be increased by raising the expansion rate of the SSAC. Based on the experimental results, the applicability of the current concrete filled steel tube design provisions for the SSSACFST stub columns is evaluated, and two analytical models for predicting the bearing capacity of the SSSACSFT stub columns under axial and eccentric compression are proposed.
Fast dynamic voltage security margin estimation: concept and development

This paper develops a machine learning-based method for fast estimation of the dynamic voltage security margin (DVSM). The DVSM can incorporate the dynamic system response following a disturbance and it generally provides a better measure of security than the more commonly used static voltage security margin (VSM). Using the concept of transient P-V curves, the paper first establishes and visualizes the circumstances when the DVSM is to prefer to the static VSM. To overcome the computational difficulties in estimating the DVSM, the paper proposes a method based on training two separate neural networks on a data set composed of combinations of different operating conditions and contingency scenarios generated using time-domain simulations. The trained neural networks are used to improve the search algorithm and significantly increase the computational efficiency in estimating the DVSM. The machine learning-based approach is thus applied to support the estimation of the DVSM, while the actual margin is validated using time-domain simulations. The proposed method was tested on the Nordic32 test system and the number of time-domain simulations was possible to reduce with approximately 70 %, allowing system operators to perform the estimations in near real-time.
Hydraulic resistance in mixed bedrock-alluvial meandering channels

ABSTRACT We present an experimental analysis of hydraulic roughness variations due to changes in alluvial cover in a mixed bedrock-alluvial meandering channel with larger bedrock roughness than alluvial roughness. Three sets of experiments were conducted in a highly sinuous flume: one with bare bedrock, and two with enough sediment to cover 21% and 78% of the bedrock respectively. We compare our results with data from experiments previously conducted in the same flume with flat- and smooth-bed, and data from experiments with fully alluvial conditions. Our results show that: (1) hydraulic resistance in a mixed bedrock-alluvial channel changes with the degree of alluviation; (2) hydraulic resistance is greater for bare-bedrock conditions, and decreases as sediment supply increases; (3) if bedforms appear, hydraulic resistance may be larger than for bare bedrock conditions due to form drag; (4) fluctuations in alluvial cover due to freely-migrating bars lead to instantaneous changes in hydraulic resistance.
Coagulase-negative staphylococci in bovine sub-clinical mastitis

Mastitis is a common disease in dairy cows. The majority of the cases are sub-clinical, and many of those are due to infection with coagulase-negative staphylococci (CNS). CNS is a heterogeneous group of bacteria consisting of a large number of different species, but limited information is available on the epidemiology of mastitis due to these species. The overall aim of the thesis was to improve the knowledge on prevalence and significance of different CNS species in connection with sub-clinical mastitis in dairy cows. In the first study, the epidemiology of CNS species, i.e. ability to induce persistent intra-mammary infections (IMI), and association with milk production, SCC, parity and month of lactation, was studied in dairy herds with problems due to sub-clinical CNS mastitis. The most commonly isolated CNS species were S. epidermidis, S. simulans, S. chomogenes, S. xylosus and S. haemolyticus. Persistent IMI were common in quarters infected with S. chromogenes, S. epidermidis and S. simulans. The results did not indicate differences between these CNS species in their association with daily milk production, cow SCC, and month of lactation. S. epidermidis was mainly found in multiparous cows, and S. chromogenes in primiparous cows. The second study concentrated on S. epidermidis by investigating possible transmission of S. epidermidis from milkers to cows, the discriminatory capacity of the sub-typing methods used and the clonal diversity within unrelated bovine S. epidermidis strains. Pulsed-field gel electrophoresis had high discriminatory power and showed that many different S. epidermidis types exist in bovine milk samples. Identical isolates were found in samples from the milker's skin and in milk samples. As dairy cows are not a natural host for S. epidermidis the results suggest a human source of these udder infections.

Identification of Specificity Determining Positions through Phylogenetic Studies and Molecular Modeling of ICP27 as a drug target of Herpes Simplex Virus-1

An ever-growing effort to apply computational power to the combined chemical and biological space in order to streamline drug discovery, design, development and optimization can be achieved through computational approaches. Herpes simplex is an infection that is caused by a herpes simplex virus (HSV), and is one of the most common human infections transmissible to a body site. Infection with HSV can result in several diseases ranging from apparent infections and self-limiting cutaneous lesions to fatal encephalitis. In the present study, the computational approach is being applied to identify the potential drug inhibitors and target receptors through computational modeling and drug designing techniques in which the ab initio modeling was performed using I-Tasser and docking was done using Autodock Vina. The docking prediction results have shown the highest binding affinity effect on the herpes viral receptor in case of 4, 5-diacetyloxy-6-(2-amino-6-oxo-3H-purin-9-yl) oxan-3-yl acetate which is an anticancer agent compared to Rimantidine and Didanosine which are used as drugs that fall under FDA-approved drug category during reproductive and latent stage of herpes simplex Virus-1. Here MSA will also have a crucial role to play in identifying the specific features, also known as “specificity determining positions” (SDPs) that modulate a protein’s function using phylogenetic study. Using these multiple in silico techniques would decrease the overall cost of research input in terms of time, money and life.

Super-Gain Optical Parametric Amplification in Dielectric Micro-Resonators via BFGS Algorithm-Based Non-Linear Programming

The goal of this paper is to show that super-gain optical parametric amplification can be achieved even in a small micro-resonator using high-intensity ultrashort pump waves, provided that the frequencies of the ultrashort pulses are tuned to maximize the intracavity magnitude of the wave to be amplified, which we call the stimulus wave. In order to accomplish this, we have performed a dispersion analysis via computational modeling of the electric polarization density in terms of the non-linear electron cloud motion and we have concurrently solved the electric polarization density and the wave equation for the electric field. Based on a series of non-linear programming-integrated finite difference time-domain simulations, we have identified the optimal pump wave frequencies that simultaneously maximize the stored electric energy density and the polarization density inside a micro-resonator by using the Broyden–Fletcher–Goldfarb–Shanno (BFGS) optimization algorithm. When the intracavity energy and the polarization density (which acts as an energy coupling coefficient) are simultaneously high, an input wave can be strongly amplified by efficiently drawing energy from a highly energized cavity. Therefore, we propose that micrometer-scale achievement of super-gain optical parametric amplification is possible in a micro-resonator via high-intensity ultrashort “pump wave” pulses, by determining the optimal frequencies that concurrently maximize the stored electric energy density and the polarization density in a dielectric interaction medium.
