Authors: Huang Hongwei , Cheng Wen , Zhou Mingliang , Chen Jiayao , Zhao Shuai
Published: November 2020

On-site manual inspection of metro tunnel leakages has been faced with the problems of low efficiency and poor accuracy. An automated, high-precision, and robust water leakage inspection method is vital to improve the manual approach. Existing approaches cannot provide the leakage location due to the lack of spatial information. Therefore, an integrated deep learning method of water leakage inspection using tunnel lining point cloud data from mobile laser scanning is presented in this paper. It is composed of three parts as follows: (1) establishment of the water leakage dataset using the acquired point clouds of tunnel linings; (2) automated leakage detection via a mask-region-based convolutional neural network; and (3) visualization and quantitative evaluation of the water leakage in 3D space via a novel triangle mesh method. The testing result reveals that the proposed method achieves automated detection and evaluation of tunnel lining water leakages in 3D space, which provides the inspectors with an intuitive overall 3D view of the detected water leakages and the leakage information (area, location, lining segments, etc.).
A Design of the Resilient Enterprise: A Reference Architecture for Emergent Behaviors Control
Authors: Bemthuis Rob , Iacob Maria-Eugenia , Havinga Paul
Published: November 2020

The sooner disruptive emergent behaviors are detected, the sooner preventive measures can be taken to ensure the resilience of business processes execution. Therefore, organizations need to prepare for emergent behaviors by embedding corrective control mechanisms, which help coordinate organization-wide behavior (and goals) with the behavior of local autonomous entities. Ongoing technological advances, brought by the Industry 4.0 and cyber-physical systems of systems paradigms, can support integration within complex enterprises, such as supply chains. In this paper, we propose a reference enterprise architecture for the detection and monitoring of emergent behaviors in enterprises. We focus on addressing the need for an adequate reaction to disruptions. Based on a systematic review of the literature on the topic of current architectural designs for understanding emergent behaviors, we distill architectural requirements. Our architecture is a hybrid as it combines distributed autonomous business logic (expressed in terms of simple business rules) and some central control mechanisms. We exemplify the instantiation and use of this architecture by means of a proof-of-concept implementation, using a multimodal logistics case study. The obtained results provide a basis for achieving supply chain resilience “by design”, i.e., through the design of coordination mechanisms that are well equipped to absorb and compensate for the effects of emergent disruptive behaviors.
FMCW LiDAR System to Reduce Hardware Complexity and Post-Processing Techniques to Improve Distance Resolution
Authors: Kim Chankyu , Jung Yunho , Lee Seongjoo
Published: November 2020

As the autonomous driving technology develops, research on related sensors is also being actively conducted. One system that is widely used today uses a light source with a wavelength in the 905 nm band for the pulse Light Detection And Ranging (LiDAR) system. This has the disadvantages of being harmful to the human eye and in making digital signal processing difficult at high sampling rates. The Frequency Modulated Continuous Wave (FMCW) LiDAR system has been proposed as an alternative. However, the FMCW LiDAR is formed with a high beat frequency by a method different from that of the FMCW Radar, which causes a hardware burden on the FFT (Fast Fourier Transform) module for interpreting the beat frequency information. In this paper, the FFT module that may occur in the FMCW LiDAR using Digital Down Convert (DDC) technology is extracted at 256 points, which is 25 times smaller than the existing 8192 points, and the beat frequency is 0 to 50 m at 3 cm intervals. As a result of generating and restoring the distance, the performance of 0.03 m Root Mean Square Error (RMSE) compared to the conventional one was confirmed. In this process, the hardware module was directly mounted and verified on the FPGA. In the case of the Simple Threshold-Constant False Alarm Rate (ST-CFAR) provided, the RMSE was measured by generating beat frequencies from 0 to 50 m at 1 cm intervals, and as a result, the result of 0.019 m was confirmed at 0.03 m in the past.
Voltage-Mode Multifunction Biquad Filter and Its Application as Fully-Uncoupled Quadrature Oscillator Based on Current-Feedback Operational Amplifiers
Authors: Wang San-Fu , Chen Hua-Pin , Ku Yitsen , Zhong Ming-Xiu
Published: November 2020

This research introduces a new multifunction biquad filter based on voltage mode (VM) current-feedback operational amplifier (CFOA) and a fully uncoupled quadrature oscillator (QO) based on the proposed VM multifunction biquad filter. The proposed VM multifunction biquad filter has high impedance to the input voltage signal, and uses three CFOAs as active components, while using four resistors and two grounded capacitors as passive components. The VM CFOA-based multifunction biquad filter realizes band-reject, band-pass, and low-pass transfer functions at high-input impedance node simultaneously, which has the feature of easy cascading in VM operation without the need for additional voltage buffers. Additionally, the filter control factor parameter pole frequency (ωo) and quality factor (Q) of the proposed VM multifunction biquad filter can be independently set by varying different resistors. By slightly modifying the VM multifunction biquad filter topology, a VM fully-uncoupled QO is easily obtained. The difference from the previous VM CFOA-based multifunction biquad filter is that the proposed VM CFOA-based multifunction biquad filter can be independently controlled by the filter control factor parameters, ωo and Q. The proposed VM CFOA-based multifunction biquad filter can be transformed into a VM QO with fully-uncoupled adjustable of the oscillation condition and the oscillation frequency. The oscillation condition and the oscillation frequency can be fully-uncoupled and controlled by varying two sets of completely different resistors. The proposed VM fully-uncoupled QO solves the amplitude instability. The constant amplitude ratio of two quadrature sinusoidal waveforms can be realized when tuning FO. PSpice simulation and experimental results prove the performances of the proposed VM multifunction filter and VM fully-uncoupled QO. Simulation and experimental results confirm the theoretical analysis of the proposed circuits.
Facilitating Hotspot Alignment in Tip-Enhanced Raman Spectroscopy via the Silver Photoluminescence of the Probe
Authors: Fan Yuan , Jin Dan , Wu Xiuju , Fang Hui , Yuan Xiaocong
Published: November 2020

A tip-enhanced Raman spectroscopy (TERS) system based on an atomic force microscope (AFM) and radially polarized laser beam was developed. A TERS probe with plasmon resonance wavelength matching the excitation wavelength was prepared with the help of dark-field micrographs. The intrinsic photoluminescence (PL) from the silver (Ag)-coated TERS probe induced by localized surface plasmon resonance contains information about the near-field enhanced electromagnetic field intensity of the probe. Therefore, we used the intensity change of Ag PL to evaluate the stability of the Ag-coated probe during TERS experiments. Tracking the Ag PL of the TERS probe was helpful to detect probe damage and hotspot alignment. Our setup was successfully used for the TERS imaging of single-walled carbon nanotubes, which demonstrated that the Ag PL of the TERS probe is a good criterion to assist in the hotspot alignment procedure required for TERS experiments. This method lowers the risk of contamination and damage of the precious TERS probe, making it worthwhile for wide adoption in TERS experiments.
Fusion-ConvBERT: Parallel Convolution and BERT Fusion for Speech Emotion Recognition
Authors: Lee Sanghyun , Han David K. , Ko Hanseok
Published: November 2020

Speech emotion recognition predicts the emotional state of a speaker based on the person’s speech. It brings an additional element for creating more natural human–computer interactions. Earlier studies on emotional recognition have been primarily based on handcrafted features and manual labels. With the advent of deep learning, there have been some efforts in applying the deep-network-based approach to the problem of emotion recognition. As deep learning automatically extracts salient features correlated to speaker emotion, it brings certain advantages over the handcrafted-feature-based methods. There are, however, some challenges in applying them to the emotion recognition problem, because data required for properly training deep networks are often lacking. Therefore, there is a need for a new deep-learning-based approach which can exploit available information from given speech signals to the maximum extent possible. Our proposed method, called “Fusion-ConvBERT”, is a parallel fusion model consisting of bidirectional encoder representations from transformers and convolutional neural networks. Extensive experiments were conducted on the proposed model using the EMO-DB and Interactive Emotional Dyadic Motion Capture Database emotion corpus, and it was shown that the proposed method outperformed state-of-the-art techniques in most of the test configurations.

Published: November 2020

Sandwich panels consisting of two Carbon Fibre Reinforced Polymer (CFRP) outer skins and an aluminium honeycomb core are a common structure of surfaces on commercial aircraft due to the beneficial strength–weight ratio. Mechanical defects such as a crushed honeycomb core, dis-bonds and delaminations in the outer skins and in the core occur routinely under normal use and are repaired during aerospace Maintenance, Repair and Overhaul (MRO) processes. Current practices rely heavily on manual inspection where it is possible minor defects are not identified prior to primary repair and are only addressed after initial repairs intensify the defects due to thermal expansion during high temperature curing. This paper reports on the development and characterisation of a technique based on conductive thermography implemented using an array of single point temperature sensors mounted on one surface of the panel and the concomitant induced thermal profile generated by a thermal stimulus on the opposing surface to identify such defects. Defects are classified by analysing the differential conduction of thermal energy profiles across the surface of the panel. Results indicate that crushed core and impact damage are detectable using a stepped temperature profile of 80 ∘C The method is amenable to integration within the existing drying cycle stage and reduces the costs of executing the overall process in terms of time-to-repair and manual effort.
Excess Air Ratio Management in a Diesel Engine with Exhaust Backpressure Compensation
Authors: Kasprzyk Piotr , Hunicz Jacek , Rybak Arkadiusz , Gęca Michał S. , Mikulski Maciej
Published: November 2020

The paper investigates the operation of a wideband universal exhaust gas oxygen (UEGO) sensor in a diesel engine under elevated exhaust backpressure. Although UEGO sensors provide the excess air ratio feedback signal primarily in spark ignition engines, they are also used in diesel engines to facilitate low-emission combustion. The excess air signal is used as an input for the fuel mass observer, as well as to run the engine in the low-emission regime and enable smokeless acceleration. To ensure a short response time and individual cylinder control, the UEGO sensor can be installed upstream of a turbocharger; however, this means that the exhaust gas pressure affects the measured oxygen concentration. Therefore, this study determines the sensor’s sensitivity to the exhaust pressure under typical conditions for lean burn low-emission diesel engines. Identification experiments are carried out on a supercharged single-cylinder diesel engine with an exhaust system mimicking the operation of the turbocharger. The apparent excess air measured with the UEGO sensor is compared to that obtained in a detailed exhaust gas analysis. The comparison of reference and apparent signals shows that the pressure compensation correlations used in gasoline engines do not provide the correct values for diesel engine conditions. Therefore, based on the data analysis, a new empirical formula is proposed, for which the suitability for lean burn diesel engines is verified.

Published: November 2020

Проаналізовано та узагальнено теоретико-методологічних підходів щодо демократизації суспільно-політичних відносин як основи демократизації влади. Розглянуто ключові питання впливу сформованих суспільно-політичних цінностей на розвиток демократії. Визначено, що демократизація ‒ необхідна передумова розвитку духовної культури, всебічного розповсюдження духовного процесу, де акцент робиться на обізнаності культури загальнолюдських цінностей, ідеалів та принципів. Обґрунтовано, що демократизація суспільно-політичних відносин сприятиме задоволенню потреб і інтересів громадян та призведе до підвищення авторитету як владних структур, так і інститутів громадянського суспільства. Для вдосконалення процесу демократизації суспільно-політичних відносин необхідно розвивати та стимулювати формування ключових демократичних цінностей, таких як: професіоналізм керівників урядів на різних рівнях влади; ефективність, підзвітність гілок влади; орієнтація на соціальні потреби країни з урахуванням минулого історичного досвіду; відкрита, прозора, некорумпована та соціально орієнтована система політичних відносин.

У статті розглядається сучасна концептуалізація громадянського суспільства як реакція на усвідомлення обмеженість його ліберальної теоретичної традиції з її спрощеним інституціональним ототожненням громадянського суспільства з добровільними асоціаціями та НДО. Зокрема, аналізується заклик Дж. Александера відмовитись від фокусу виключно на формальних інституціях демократії. Цей рух поза інституціональний підхід дозволяє відкрити другий культурний, вимір громадянського суспільства як солідарності спільноти, що спирається на цивільний культурний код всупереч нецивільному. В запропонованій теоретичній схемі бінарних культурних кодів громадянського суспільства детально відстежується просування з рівня мотивів діючого актора через рівень відносин до третього рівня інститутів, реальний зміст яких визначається відповідним сакральним культурним кодом. Доповнення інституційного рівня громадянського суспільства аналізом його культурного рівня також дозволяє дослідити більш складну взаємодію громадянського суспільства та демократії.
ПРОБЛЕМА НАЦІОНАЛЬНОГО СУВЕРЕНІТЕТУ В КОНТЕКСТІ СУЧАСНИХ МІЖНАРОДНИХ ВІДНОСИН
Authors: Поліщук О. О.
Published: November 2020

У статті розглядаються різні аспекти проблеми національного суверенітету в сучасних міжнародних відносинах. Пропонується визначення змісту «суверенітет» у широкому історичному контексті, здійснюється стислий огляд розвитку змісту цього поняття, досліджуються причини і наслідки трансформації цього феномену в сучасних умовах.

Зазначається, що як і багато інших термінів соціально-гуманітарних дисциплін поняття «суверенітет» не має загального й однозначного визначення, а відмінності у його трактуванні зазвичай суперечать одна одній. Наголошується, що головна причина цього є те, що феномен «суверенітет» знаходився в процесі постійного розвитку, в межах якого держави створювали, втрачали і передавали іншим політичним акторам частину своїх державних функцій. Саме тому теоретичні уявлення про суверенітет і практика їх реалізації суттєво відрізнялися. Обґрунтовується, що перспективним для сучасної політичної науки є визначення суверенітету держави, що передбачає існування двох основних аспектів: здатність держави самостійно представляти свою владу на території, яка окреслена державним кордоном або позначена іншими ознаками належності до даної території, яку держава контролює, та спроможність самостійно приймати рішення в міжнародних відносинах.

Contemporary Tamil novels depict human life in different dimensions with aesthetic fineness, depending on some theories, in the background of countries such as Sri Lanka, Singapore, Malaysia, etc., and also the places of refuge and diaspora. Here, we mark Sri Lankan Tamil novels, that the writer should belong to Sri Lanka. He may live in some other diasporic country. Even when they write from any of the diasporic countries like France, Canada, Denmark, Australia, etc., one could observe the smell of flesh and blood of their motherland. We can point out Shobha Shakthi’s – Gorilla, m, box; Tamil Nadhi’s- Parthenium; Tamil Kavi’s –Uuzhi kaalam; Jeevakumar’s –kudhitrai vaahanam.

Authors: R Mathan kumar
Published: November 2020

In today’s mechanical world, there is no use of learning some of the exercises only in the name of yoga. According to Tirumoolar, yoga is the purification of the body, mind, action and wound. The yoga practice that encompasses this concept is offered as Attanga Yoga in Thirumanthiram.  The human soul has bounded knowledge where the Thiruvarul is performing as instrument to practice Attanga Yoga. According to Thirumoolar, Attaining Attamasithi through Attanga Yoga is not the completion of practicing yoga; Attaining seevanmuthan stage is the final stage where yogis can feel fulfillment through Ataanga Yoga. The soul gets the superior birth as human being through it’s benevolence of previous birth. By the grace of god, soul attains Iruvinaioppu, Malaparipakam and Thiruvarulvizhchi. In that improved stage, Thiruvarul exists as Gnanaguru and leads the soul to Attanga Yoga and the Thava Yoga. This practice also called as Raja-yogam. Through the practice of Attanga Yoga, soul attains the Attama sithis and realizes that the Thiruvarul is the part of Sivam. As Thiruvarul incorporates in sivam, the soul will realize it’s incorporation in sivam with limitless knowledge. This consciousness helps the soul to have strong bonding with siva. The attitude expresses the blissful movement of the soul. This experience stated as Siva-Gnana-yogam. Thus this article explains the virtues of attaining the bliss of living, Sivanupavam, through the path of Thirumanthiram.

Published: November 2020

Noninvasive epi-endocardial ElectroCardioGraphic Imaging (ECGI) allows reconstruction of electrograms and high-resolution visualization of various isoparametric maps based on multichannel ECG recordings and tomography. We aimed to verify the ECGI accuracy during septal ventricular pacing in patients with pre-implanted pacemakers using the new ECGI algorithm.

Methods. Ten patients underwent epi-endocardial ECGI mapping (Amycard 01C EP Lab, Amycard LLC, Russia - EP Solutions SA, Switzerland). The iterative Equal Single Layer algorithm (ESL-iterative) and a new Fast Route algorithm in combination with the vector approach (FRA-V) were used to reconstruct isopotential and correlation similarity maps. Geodesic distance between noninvasively reconstructed early activation zone and RV reference pacing sites were measured to evaluate the ECGI accuracy.

Results. The mean (SD) geodesic distance between noninvasively identified sites and reference pacing sites was 22 (15) mm for the ESL-iterative and 12 (7) for FRA-V algorithms, median (25-75% IQR) - 23 (8-29) mm and 10 (8-14) mm, respectively. The accuracy of ECGI mapping based on the FRA-V algorithm was significantly better than ESL-iterative algorithm (p=0,01). A detailed visual analysis of correlation similarity and isopotential maps showed significantly more accurate localization of early activation zones using the new FRA-V algorithm.

Conclusions. Our study showed the feasibility and accuracy of a novel epi-endocardial ECGI mapping approach to identify early activation zones during septal ventricular pacing using the new FRA-V algorithm. The FRA-V algorithm is significantly better for epi-endocardial ECGI mapping and shows a significant advantage of this technique compared to other non-invasive methods of topical diagnostics. Moreover, simultaneous beat-to-beat mapping of entire ventricular septum allows using this technique for pre-ablation evaluation of unstable and polymorphic ventricular arrhythmia exit sites.

Published: November 2020

Aim:we aimed to assess the capabilities of “machine learning” methods in predicting remote outcomes in patients with non-valvular atrial fi brillation (AF).

Methods.From 2015 to 2016 234 patients with non-valvular AF were included in the study (median age 72 (65; 79) years; 50.0% men). During the median follow-up of 2.9 (2.7; 3.2) years 42 patients died, 9 patients had non-fatal acute cerebral circulatory disorders and 3 patients had non-fatal myocardial infarction (MI). These events in 52 subjects (22.2% from all patients included) were combined into a combined endpoint (death and a nonfatal cardiovascular accident at the stage of remote observation). The first 184 patients comprised a “training” group. The next 50 patients formed the “test” group. The following methods of «machine learning» were used in the analysis: classifi cation trees, linear discriminant analysis, the k-nearest neighbor method, support vectors method, neural network.

Results.Long-term outcomes were influenced by age, known traditional risk factors for cardiovascular diseases, the presence of these diseases, changes in intracardiac hemodynamics and heart chambers as evaluated by echocardiography, the presence of concomitant anemia, advanced stages of chronic kidney disease, and the administration of drugs associated with a more severe cardiovascular disease progression (amiodarone, digoxin). The best prognosis was created using the model of linear discriminant analysis, the complex neural network model, and the support vector machine.

Conclusion.Modern methods aimed at prognosis estimation seem to be of importance in cardiology. These methods include big data analysis and machine learning technologies. The methods require further evaluation and confirmation, and in the future they may allow correcting cardiovascular risks, using data from real clinical practice and evidence-based medicine at the same time.

Introduction:Coronary artery bypass grafting (CABG) might be associated with the development of heart rhythm disturbances. We aimed at evaluating an association of intraoperative hemolysis (IOH) with the development of cardiac rhythm disturbances in patients with coronary artery disease after on-pump CABG.

Methods.The assessment of the degree of IOH was performed according to the level of plasma free hemoglobin [Hb] at baseline, immediately after the patient was connected to the cardiopulmonary bypass (CPB) device and 15 minutes before cessation of CPB. We included 123 patients, and they were divided into 3 groups (gr.) according to free [Hb] level: gr.1 - ≤0.1 g/l; gr.2 - > 0.1 g/l and <0,5 g/l; gr.3 - ≥0.5 g/l. A variety of ECG screening methods were applied for the detection of cardiac arrhythmia in the postoperative period. The follow-up period was 1 months.

Results.Arrhythmias were observed in 2.3% of patients in the 1st group, in 11.9% in the 2nd group, and in 52.6% in the 3rd group. The level of plasma free [Hb] in samples taken at the end of CPB was strongly associated with the arrhythmia detection (rs=0,70, p <0.001). Life-threatening and hemodynamically unstable arrhythmias were more frequently detected in the group with a higher degree of IOH (p <0.001), and accounted for about half of all arrhythmias.

Conclusions.On-pump CABG is associated with the development of cardiac arrhythmias in the postoperative period in 22% of patients. A significant proportion of these arrhythmias are potentially life-threatening. The highest proportion of patients with cardiac rhythm disturbances after CABG was observed when the level of plasma free hemoglobin was >0.5 g.

Market prediction has been the goal of many study as investors sought traded assets since the inception of the capital market. With each asset exchanged for money, investors seek to stay ahead the market trend in the hope of amassing profits. Businesses’ growth (rise/fall) is evident upon their response to market behaviour. Thus, accurate prediction of the market often offers as its reward, enlarged financial portfolio. Market participants thus, seek to manage the risks associated with asset prices and its volatility, which can be rippled with chaos and complex tasks arising from a demand-supply curve. We seek to model the Oil market and forecast its price direction supported with empirical evidence using ARIMA model to analyze inputs in search of an optimal solution. We adopt the OPEC model to: (a) predict spot/futures-prices, (b) investigate why previous prediction was poor and price plummeted, and (c) compares value(s) from Ojugo and Yoro (2020) and Ojugo and Allenotor (2017). Results shows demand-supply curve rise (and a price rise) even though the policies and trend in real life scenario is currently experiencing a price plummet.

Формування щільної забудови, середньої поверховості
Authors: Михновець Петро , Гнат Галина
Published: November 2020

У даній науковій статті досліджена тема «формування щільної забудови, середньої поверховості». Актуальність на сьогодні, неймовірно висока, у зв’язку з негативними наслідками швидкої індустріалізації суспільства. Старі індустріальні райони занепадають і не використовуються належним чином. Крім того, у зв’язку з високою ціною на земельні ділянки, правильне використання функціональних зон при проектуванні та їх ущільнення, допоможе сформувати зручне та щільне житло. Дослідження було проведено аналітичним методом, через аналіз існуючих закордонних об’єктів. Це дало змогу проаналізувати реальний стан ситуації, оскільки сучасні норми проектування не відображають реальних побажань мешканців. А це дослідження показує, що люди згідні на деякі не нормативні рішення (наприклад зменшення розривів між будинками, фасади яких не глухі), але в заміну вони мають отримати рішення їх реальних потреб: хороша організація сміттєзбирання, змога паркування при відсутності машин у внутрішньому дворі і тощо).
