Rules and validation processes for interoperable BIM data exchange

Abstract Diverse industries have recognized the significance of a neutral data standard for seamless building information modeling (BIM) data exchanges and adopted commonly agreed schemes such as the industry foundation classes (IFC) schema for enhancing BIM data interoperability. To selectively employ domain-specific data exchange requirements, the AEC-FM (the Architecture, Engineering, Construction, and Facility Management) industries have developed their own schema with a subset of the IFC schema, named a model view definition (MVD). However, because of latent human errors, inadequate MVD definitions, and error-prone data mapping problems, the adoption of IFC for exchanging and sharing BIM data is frequently limited with severe data integrity issues. This challenging situation requires the detailed examination of the limitations of the heterogeneous IFC translation processes of the current BIM authoring and application tools. To accomplish this objective, the authors thoroughly investigated the two MVDs, the Coordination View Version 2.0 and the Construction Operations Building Information Exchange, broadly used as an international standard for developing the IFC translation processes, and then identified their intrinsic requirements/rules and developed rule-based data validation processes. These new intrinsic knowledge of the two MVD specifications will be fundamental foundations to create coherent BIM data exchange systems that are currently scattered and dispersed in heterogeneous IFC translation processes and structures. Newly revealed rules pertaining to these two MVDs have been executed with IfcDoc, which is the IFC documentation tool. This BIM data validation process is expected to not only accurately evaluate the translation processes between BIM native data and IFC ones but also help industry professionals ensure the integrity and the accuracy of their BIM data according to the BIM data exchange standards using the two MVDs. In addition, the outcomes of this research study are expected to bolster the interoperable BIM adoption and offer the values of greater consistency of BIM data exchange.

Combining Laue diffraction with Bragg coherent diffraction imaging at 34-ID-C.

Measurement modalities in Bragg coherent diffraction imaging (BCDI) rely on finding a signal from a single nanoscale crystal object which satisfies the Bragg condition among a large number of arbitrarily oriented nanocrystals. However, even when the signal from a single Bragg reflection with (hkl) Miller indices is found, the crystallographic axes on the retrieved three-dimensional (3D) image of the crystal remain unknown, and thus localizing in reciprocal space other Bragg reflections becomes time-consuming or requires good knowledge of the orientation of the crystal. Here, the commissioning of a movable double-bounce Si (111) monochromator at the 34-ID-C endstation of the Advanced Photon Source is reported, which aims at delivering multi-reflection BCDI as a standard tool in a single beamline instrument. The new instrument enables, through rapidswitching from monochromatic to broadband (pink) beam, the use of Lauediffraction to determine crystal orientation. With a proper orientation matrixdetermined for the lattice, one can measure coherent diffraction patterns near multiple Bragg peaks, thus providing sufficient information to image the full strain tensor in 3D. The design, concept of operation, the developed procedures for indexing Laue patterns, and automated measuring of Bragg coherent diffraction data from multiple reflections of the same nanocrystal arediscussed.

PENGARUH KUALITAS AKTIVA PRODUKTIF DAN NET PERFORMING FINANCING (NPF) TERHADAP NET OPERATING MARGIN (NOM) BANK UMUM SYARIAH DAN UNIT USAHA SYARIAH PERIODE JUNI 2014 – MARET 2020

Net Operating Margin (NOM) is a ratio that is needed to improve the ability of banks to manage their entire productivity in order to produce a higher net. While Non-Performing Financing (NPF) is an indicator of credit risk (financing) of Islamic banks. Banks with high NPFs are less effective. Consider a bank with a lower NPF, more efficient. This study aims to look at the effect of Earning Asset Quality and Non-Performing Financing (NPF) on Net Operating Margin (NOM) in Sharia Commercial Banks and Sharia Business Units. The data used in this study is monthly coherent data from the period June 2014 to March 2020. Technical data analysis uses multiple regression models that are processed with IBM SPSS V.26.0. The results showed that the Earning Assets Quality (KAP) had a significant negative effect on the Net Operating Margin (NOM) variable with a KAP coefficient of -0.017 with a significance level of 0.610. Net Performing Financing (NPF) has a significant negative effect on the Net Operating Margin (NOM) variable with a NPF coefficient of - 0.482 with a significance level of 0,000. F test results (simultaneous) Earning Asset Quality (KAP) and Net Performing Financing (NPF) have a significant effect on the Net Operating Margin (NOM) of BUS and UUS. Test the coefficient of determination (Adjusted R Square) of 0.732 or of 73.2%. This shows that Earning Asset Quality (KAP) and Net Performance Financing (NPF) contributed 73.2% to Net Operating Margin (NOM). While the remaining 26.8% was placed by other variables outside this study.

Physics results from the first COHERENT observation of coherent elastic neutrino-nucleus scattering in argon and their combination with cesium-iodide data

We present the results on the radius of the neutron distribution in $^{40}\text{Ar}$, on the low-energy value of the weak mixing angle, and on the electromagnetic properties of neutrinos obtained from the analysis of the coherent neutrino-nucleus elastic scattering data in argon recently published by the COHERENT collaboration, taking into account proper radiative corrections. We present also the results of the combined analysis of the COHERENT argon and cesium-iodide data for the determination of the low-energy value of the weak mixing angle and the electromagnetic properties of neutrinos. In particular, the COHERENT argon data allow us to improve significantly the only existing laboratory bounds on the electric charge $q_{\mu\mu}$ of the muon neutrino and on the transition electric charge $q_{\mu\tau}$.

Evolution of Haemophilia Care in Europe: 10 years of the principles of care

IntroductionThe European principles of care in haemophilia marked their first decade in 2018. These guiding principles were the beginning of the European Haemophilia Consortium (EHC) review of countries’ adherence to these principles in 2009, 2012, 2015 and 2018. The aim of this paper was to examine the implementation of the principles and how they have impacted the evolution of care in the last decade, as well as to identify remaining gaps and proposes future directions.MethodsIn 2018, the EHC distributed a survey to EHC national member organisations in English and Russian and encouraged them to discuss responses with local clinicians for accuracy. Data was also cross-referenced and validated for countries in earlier surveys using additional available resources.ResultsThe 10-year-old European principles had a significant impact on the development of care for haemophilia and related bleeding disorders in Europe. They set objectives around which multi-stakeholder groups have established recommendations and specific steps for the progressive improvement of care for bleeding disorders. However, some have been promoted and implemented more than others.ConclusionMonitoring adherence to, and impact of, the European Principles of Care significantly assists in tracking developments and highlighting gaps. Countries’ inability to report consistent and coherent data remains a challenge and hinders both provision of treatment and care for patients as well as optimal national and European healthcare systems.

Analisis Ketersediaan Dan Kebutuhan Beras di Provinsi Sumatera Utara

This study aims to determine and analyze the availability and need of rice in North Sumatra Province and determine the factors that influence it. This type of research is a quantitative analysis using coherent secondary data from 2008-2017 in 33 districts / cities in North Sumatra Province. The data analysis technique used is Descriptive Analysis. To test the factors that influence the availability and need of rice in North Sumatra Province, multiple linear regression analysis is used and to determine the causal relationship between variables, we use Causal Relations Analysis. The results showed that rice production in North Sumatra Province was fluctuating in 2008-2017 and tended to increase by an average of 4.79 percent per year. The availability of this rice comes from local production and has met the needs of the community. This is indicated by the condition of the rice surplus in North Sumatra Province in 2017 which amounted to 1,065,886 tons. The availability of rice in North Sumatra Province on average has increased 5.27 percent per year. Based on the results of the study note that the rice production variable has a positive and significant effect on the availability of rice in North Sumatra Province, while other variables namely the rice harvest area variable and the need for rice consumption have no significant effect. GRDP income variable and rice availability variable significantly influence rice needs in North Sumatra Province, while the population number variable does not significantly influence rice demand.

Stimulated Brillouin laser-based carrier recovery in a high-Q microcavity for coherent detection.

We demonstrate all-optical carrier recovery exploring a stimulated Brillouin laser (SBL) in a high-Q whispering-gallery-mode microcavity, to achieve coherent data detection without requiring an independent local oscillator laser. An ultra-high optical signal-to-noise ratio better than 70 dB is achieved for the recovered carrier, thanks to the fact that the generated SBL counter-propagates with the incoming data signal and experiences high SBS efficiency. High-frequency stability is obtained between the recovered carrier tone and the original data signal, enabling high-performance coherent detection without the need of electrical frequency drift compensation. This Letter offers a low complexity, high energy efficiency, and high robust carrier recovery solution.

A Two-Population Extension of the Exponential Smoothing State Space Model with a Smoothing Penalisation Scheme

The joint modelling of mortality rates for multiple populations has gained increasing popularity in areas such as government planning and insurance pricing. Sub-groups of a population often preserve similar mortality features with short-term deviations from the common trend. Recent studies indicate that the exponential smoothing state space (ETS) model can produce outstanding prediction performance, while it fails to guarantee the consistency across neighbouring ages. Apart from that, single-population models such as the famous Lee-Carter (LC) may produce divergent forecasts between different populations in the long run and thus lack the property of the so-called coherence. This study extends the original ETS model to a two-population version (2-ETS) and imposes a smoothing penalisation scheme to reduce inconsistency of forecasts across adjacent ages. The exponential smoothing parameters in the 2-ETS model are fitted by a Fourier functional form to reduce dimensionality and thus improve estimation efficiency. We evaluate the performance of the proposed model via an empirical study using Australian female and male population data. Our results demonstrate the superiority of the 2-ETS model over the LC and ETS as well as two multi-population methods - the augmented common factor model (LL) and coherent functional data model (CFDM) regarding forecast accuracy and coherence.

Multiscale proper orthogonal decomposition (mPOD) of TR-PIV data—a case study on stationary and transient cylinder wake flows

Data-driven decompositions of particle image velocimetry (PIV) measurements are widely used for a variety of purposes, including the detection of coherent features (e.g. vortical structures), filtering operations (e.g. outlier removal or random noise mitigation), data reduction and compression. This work presents the application of a novel decomposition method, referred to as multiscale proper orthogonal decomposition (mPOD, Mendez et al 2019) to time-resolved PIV (TR-PIV) measurement. This method combines multiresolution analysis and standard proper orthogonal decomposition (POD) to achieve a compromise between decomposition convergence and spectral purity of the resulting modes. The selected test case is the flow past a cylinder in both stationary and transient conditions, producing a frequency-varying Karman vortex street. The results of the mPOD are compared to the standard POD, the discrete Fourier transform and the dynamic mode decomposition. The mPOD is evaluated in terms of decomposition convergence and time-frequency localization of its modes. The multiscale modal analysis allows for revealing beat phenomena in the stationary cylinder wake, due to the three-dimensional nature of the flow, and to correctly identify the transition from various stationary regimes in the transient test case.

The application of Buckingham π theorem to Lattice-Boltzmann modelling of sewage sludge digestion

For the first time, a set of Lattice-Boltzmann two-way coupling pointwise Euler-Lagrange models is applied to gas mixing of sludge for anaerobic digestion. The set comprises a local model, a “first-neighbour” (viz., back-coupling occurs to the voxel where a particle sits, plus its first neighbours) and a “smoothing-kernel” (forward- and back-coupling occur through a smoothed-kernel averaging procedure).Laboratory-scale tests display grid-independence problems due to bubble diameter being larger than voxel size, thereby breaking the pointwise Euler-Lagrange assumption of negligible particle size. To tackle this problem and thereby have grid-independent results, a novel data-scaling approach to pointwise Euler-Lagrange grid independence evaluation, based on an application of the Buckingham π theorem, is proposed.Evaluation of laboratory-scale flow patterns and comparison to experimental data show only marginal differences in between the models, and between numerical modelling and experimental data. Pilot-scale simulations show that all the models produce grid-independent, coherent data if the Euler-Lagrange assumption of negligible (or at least, small) particle size is recovered. In both cases, a second-order convergence was achieved.A discussion follows on the opportunity of applying the proposed data-scaling approach rather than the smoothing-kernel model.

Compound Coherent Plane-Wave Ultrasound Imaging of Vascular Malformations of the Orbit.

Prior color-flow Doppler ultrasound studies of the eye have been performed with systems that exceed US Food and Drug Administration permissible ophthalmic ultrasonic energy limits. The authors report a study of orbital vascular malformations using a novel, Food and Drug Administration compliant, ultrafast compound coherent plane-wave ultrasound device to produce power Doppler images. Using a Verasonics Vantage 128 ultrasound engine and a user-developed MATLAB program with a 5-MHz linear-array probe, compound coherent plane-wave ultrasound data were collected on patients with orbital vascular malformations. Real-time color-flow Doppler visualized orbital blood flow. Power Doppler images were produced by post-processing compound coherent plane-wave ultrasound data acquired continuously for 2 seconds. Compound coherent plane-wave ultrasound was performed on 3 orbital vascular malformations (1 venolymphatic malformation, 1 infantile hemangioma, and 1 arteriovenous malformation). Compound coherent plane-wave ultrasound produced a high-resolution depiction of orbital blood flow for orbital vascular malformations with high sensitivity to slow flow. Analysis of blood flow within orbital lesions informs treatment planning. Compound coherent plane-wave ultrasound is an emerging ultrasound modality that falls within the Food and Drug Administration guidelines for use in the orbit and provides information to characterize orbital vascular malformations.

Non-standard neutrino interactions in U(1)\u2032 model after COHERENT data

We explore the potential to prove light extra gauge Z′ boson inducing nonstandard neutrino interactions (NSIs) in the coherent-elastic neutrino-nucleus scattering (CEνNS) experiments. We intend to examine how the latest COHERENT-CsI and CENNS-10 data can constrain this model. A detailed investigation for the upcoming Ge, LAr-1t, and NaI detectors of COHERENT collaboration has also been made. Depending on numerous other constraints coming from oscillation experiments, muon (g −2), beam-dump experiments, LHCb, and reactor experiment CONUS, we explore the parameter space in Z′ boson mass vs coupling constant plane. Moreover, we study the predictions of two-zero textures that are allowed in the concerned model in light of the latest global-fit data.

The Application of Seismic Three Dimensional Coherence Analysis Techniques in the Fine Structure Study of Oilfield

In recent years, with the emergence, wide application and continuous improvement of high-precision (high resolution) seismic acquisition technology, coherent data volume interpretation technology, 3d visualization technology and spectral decomposition technology, the identification ability and interpretation accuracy of seismic data interpretation have been greatly improved. Especially in the process of rolling edge expansion and development adjustment in the old oilfield, the small faults and microstructures in the oilfield have become one of the key contents of fine structure interpretation.

Harmonizing structural mass spectrometry analyses in the mass spec studio

Structural Mass Spectrometry (SMS) provides a comprehensive toolbox for the analysis of protein structure and function. It offers multiple sources of structural information that are increasingly useful for integrative structural modeling of complex protein systems. As MS-based structural workflows scale to larger systems, consistent and coherent data interpretation resources are needed to better support modeling. Unlike the proteomics community, practitioners of SMS lack adequate computational tools. Here, we review new developments in the Mass Spec Studio: an expandable ecosystem of workflows for the analysis of complementary SMS techniques with linkages to modeling. Current functionality in the Studio (version 2) supports three major SMS workflows (crosslinking, hydrogen/deuterium exchange and covalent labelling) and two pipelines for structural modeling, with a special focus on data integration. The Mass Spec Studio is an architecture focused on rapid and robust extension of functionality by a community of developers. SignificanceThis review surveys the new data analysis capabilities within the Mass Spec Studio, a rich framework for rapid software development specifically targeting the community of structural proteomics and structural mass spectrometry. Updates to crosslinking, hydrogen/deuterium-exchange and covalent labeling apps are provided as well as a utility for translating such analyses into restraints that support integrative structural modeling. These new capabilities, together with the underlying design tools and content, provide the community with a wealth of resources to tackle complex structural problem and design new approaches to data analysis.

Ultra-dense optical data transmission over standard fibre with a single chip source

Micro-combs - optical frequency combs generated by integrated micro-cavity resonators – offer the full potential of their bulk counterparts, but in an integrated footprint. They have enabled breakthroughs in many fields including spectroscopy, microwave photonics, frequency synthesis, optical ranging, quantum sources, metrology and ultrahigh capacity data transmission. Here, by using a powerful class of micro-comb called soliton crystals, we achieve ultra-high data transmission over 75 km of standard optical fibre using a single integrated chip source. We demonstrate a line rate of 44.2 Terabits s−1 using the telecommunications C-band at 1550 nm with a spectral efficiency of 10.4 bits s−1 Hz−1. Soliton crystals exhibit robust and stable generation and operation as well as a high intrinsic efficiency that, together with an extremely low soliton micro-comb spacing of 48.9 GHz enable the use of a very high coherent data modulation format (64 QAM - quadrature amplitude modulated). This work demonstrates the capability of optical micro-combs to perform in demanding and practical optical communications networks.

All-Analog Adaptive Equalizer for Coherent Data Center Interconnects

In a high-speed coherent optical transmission system, typically the signals obtained at the receiver front-end are digitized using very high-speed ADCs and then processed in the digital domain to remove optical channel impairments. In this work, we show that these signals can instead be processed in the analog domain itself, which can significantly reduce the power consumption as well as the complexity of the receiver. The first all-analog adaptive equalizer for receivers of coherent dual-polarization optical links has been presented with its detailed architecture and measurement results. The proof-of-concept equalizer uses the constant modulus algorithm for blind adaptation of its weight coefficients to implement a 4x4 2-tap FIR filter in 130 nm SiGe BiCMOS technology. Its functionality is evaluated experimentally for 40 Gb /s data rate and 10 km standard single-mode fiber channel. This demonstration shows that the use of all-analog processing for short-reach data-center interconnects is feasible and is a much simpler solution than the use of the high-speed ADC+DSP based approach. Moreover, when implemented in advanced CMOS or FinFET technologies, the power consumption of the equalizer is expected to be significantly lower than the DSP based implementations in similar process technologies.

Fiber-Longitudinal Anomaly Position Identification Over Multi-Span Transmission Link Out of Receiver-end Signals

We have developed a fiber-longitudinal monitor that visualizes distance-wise optical power throughout the entire multi-span link by using the signal waveform obtained by a coherent receiver placed at the receiver-end. This is an in-situ monitor that estimates power profile along the link-longitudinal axis from its incoming signal by employing digital post-processing of coherent receiver data. We demonstrate through experiments that our method can simultaneously visualize and localize multiple power attenuation anomalies over fiber transmission links. This data processing-based monitoring by digital coherent receiver will be a key element in future autonomous optical networks driven by rich information on physical-layer.

"notame": Workflow for Non-Targeted LC-MS Metabolic Profiling.

Metabolomics analysis generates vast arrays of data, necessitating comprehensive workflows involving expertise in analytics, biochemistry and bioinformatics in order to provide coherent and high-quality data that enable discovery of robust and biologically significant metabolic findings. In this protocol article, we introduce notame, an analytical workflow for non-targeted metabolic profiling approaches, utilizing liquid chromatography–mass spectrometry analysis. We provide an overview of lab protocols and statistical methods that we commonly practice for the analysis of nutritional metabolomics data. The paper is divided into three main sections: the first and second sections introducing the background and the study designs available for metabolomics research and the third section describing in detail the steps of the main methods and protocols used to produce, preprocess and statistically analyze metabolomics data and, finally, to identify and interpret the compounds that have emerged as interesting.

European compact against tax fraud—VAT solidarity and new dimension of effective and coherent tax data transfer

The aim of this article is to present a new concept and scope of exchange of VAT information/data and tax technologies between EU Member States, better designed to combat VAT fraud. In the authors’ view, bilateral agreements on strengthened cooperation are a more effective solution—at least in the short and medium term—than EU legislation. Bilateral agreements in the field of VAT already exist between some EU Member States and work effectively for the better and more structured exchange of tax data. Effective cooperation based on bilateral agreements/intergovernmental agreements could positively influence EU legislation and serve as an effective sandbox for the introduction of new common solutions for the EU legislator.

An Analysis on Investment, Government Expenditures, and Gross Domestic Revenue on Employment in North Sumatera

Employment is basically a problem which is faced by all regions, but its intensity may vary, based the factors which influence it. Employment exists because of investment and attempts to extend employment because of other factors such as inflation, interest rate, exchange rate, government expenditures, and PDRB (Gross Domestic Revenue). The objective of the research was to analyze the influence of exogenous variables on endogenous variables such as employment, inflation, interest rate, exchange rate, investment, government expenditures, and PDRB. The research used quantitative analysis by using coherent secondary data from 1985 until 2015 obtained from BPS (Central Bureau of Statistics) ofNorth Sumatera and Bank Indonesia. The data were analyzed by using path analysis model. The result of the research showed that exogenous variables simultaneously had significant influence on endogenous variables in each equation model. The variables of investment, government expenditures, gross domestic revenue, inflation, and interest rate did not have any significant influence on the variable of employment. Meanwhile, the variable of exchange rate had positive and significant influence on the variable of employment. Therefore, it is recommended that the variable of exchange rate became theattention of the North Sumatera Provincial Administration.
