Core Orientations for 4.0 Technology Application on the Development Strategy of Intelligent Transportation System in Vietnam

The Industrial Revolution 4.0 is having a substantial impact on countries in many fields such as industry structure, human resource needs, production management systems. Transportation is a high-community industry, so it will also be strongly affected by this industrial revolution. The achievements of Industry 4.0 can reshape the nation's transportation systems. That poses challenges for transportation managers to change the operating model as well as the transport-related policies. Building and developing intelligent transport systems (ITS) is attracting considerable attention, research, and investment to serve the development of transportation systems in the world as well as in Vietnam. Vietnam is gradually building Intelligent Governments, Intelligent Cities, and the Intelligent Transportation system will be an essential part of that development and entering the stage of access to the 4.0 industrial revolution, building a smart city applying 4.0 technology to bring convenience, friendliness, and safety to people in each city. As a step ahead, the Transport industry gradually realizes its dream of developing intelligent transportation in developed cities like Hanoi and Ho Chi Minh City. The paper presents an overview of the impact of Industry 4.0 on key aspects of the transport sector in general and ITS development strategy in Vietnam. On that basis, state-of-the-art technologies - technology 4.0 are proposed to meet the demands of intelligent transportation development. The paper will show that 4.0 technology is the key to the development of ITS in Vietnam.
Direct remaining useful life prediction based on multi-sensor information integrations by using evidence theory

Estimation of remaining useful life (RUL) is one of most interesting subjects in prognostic and health management. Performing an analysis of the results of such estimation can increase the reliability and the safety of the system, and reduce the unnecessary costs. In this paper, a similarity-based combination method is proposed to combine several run-to-failure historical datasets in order to directly estimate the RUL. In this method, reference datasets are clustered and the initial RUL is calculated based on the artificial neural networks trained by the reference datasets. By using the extended Dempster-Shafer, the similarity between the initial RUL and the average RUL for each dataset is obtained. The proposed methodology is tested and validated on Commercial Modular Aero-Propulsion System Simulation (C-MAPSS), test-bed developed by NASA. The results of the evaluation show that the proposed method outperforms other methods in the literature.
Fidelity of Cotton Fiber Maturity Measurement by Image Analysis

Abstract Accurate measurement of cotton fiber maturity is essential for use by the textile industry. Indirect measurements of fiber maturity by several methods such as AFIS (Advanced Fiber Information System), FMT (Fitness and Maturity Tester), NIR (Near Infrared Spectroscopy), and VIS/NIR (Visible/Near Infrared Spectroscopy) are currently being used or being developed in different segments of the textile industry. Availability of an accurate reference standard based on direct measurement of fiber parameters such as perimeter, degree of secondary wall thickening and maturity ratio will be beneficial. Image analysis of thin fiber cross sections is being used in our laboratory to assess these parameters to determine fiber maturity. The image analysis method involves a simple and rapid embedding procedure under controlled conditions to obtain 1-2 μm thick sections and analysis of thin fiber cross sections using a CCD camera attached to an Olympus microscope. The statistical software computes perimeter, area of the secondary wall, A, and computes circularity or ? (the ratio of the wall area, excluding lumen, to the area of a perfect circle having perimeter P). We have optimized various steps involving sampling, embedding and cross sectioning of fiber bundles to minimize errors and to improve speed, accuracy and reproducibility. Maturity ratios (M = 0.577) from the current image analysis results for the nine fiber samples from 1984 International Textile Manufacturers Federation (ITMF) Round Test cottons representing different maturity ratios showed excellent correlation (R2 = 0.88) to previously published maturity ratios as determined by FMT. Extensive statistical analyses indicated that a minimum of 529 to 1436 fibers is needed to estimate the true population means for each parameter with 99% confidence. A sample size of less than 300 fibers is needed for determining the fiber parameters with 95% accuracy. The importance of drawing representative samples from cotton bales is emphasized in this research. In summary, image analysis can serve as a reference standard for other indirect methods that are currently employed for determining fiber quality.
Obtaining the Heart Rate Information from the Speckle Images by Fractal Analysis Method

Heart rate is the main data that shows if the heart is working properly. Therefore, obtaining the heart rate information has a vital importance. There are some methods to measure the heart rate, but the most commonly used one is the Electrocardiography (ECG). However, this method is expensive and non-portable. Therewithal, optical studies have recently been conducted to measure heart rate. Being non-invasive, inexpensive, and safe are the advantages of optical measurements. Laser speckle contrast imaging is an effective and simple technique for imaging heterogeneous environments such as human and animal tissues. By laser speckle contrast analysis, heart rate can be obtained easily. It is the standard technique, but fractal analysis method is also very convenient way to study speckle images because speckle pattern is quite appropriate for studying fractality due to its granular structure. In this paper, we present fractal analysis method for obtaining heart rate information from speckle images. The results of this method for the various in-vivo and in-vitro data were compared with the reference model results of speckle contrast analysis method and it is observed that the proposed analysis method has provided sufficient results.
Peroxidases in the early responses of different potato cultivars to infection by Potato virus YNTN

Peroxidases (POXs) were investigated in three cultivars of potato (Solanum tuberosum) with different susceptibilities to infection by Potato virus YNTN (PVYNTN). Soluble, ionically-bound and covalently-bound POXs were analysed over 24 h post inoculation (hpi) in bottom inoculated leaves, upper intact leaves, and in roots. The first changes were observed at 3 hpi when the activity of ionically-bound POXs increased significantly in the inoculated leaves of tolerant cv. Pentland Squire and of resistant cv. Sante. The most pronounced changes were found in the resistant variety, where the increase was twice that in control plants. In contrast, in the inoculated leaves of susceptible cv. Igor, there was a decrease in ionically-bound POXs, accompanied by a two fold increase in the activity of covalently-bound POXs. Also at 3 hpi, cv. Sante showed increased activity of all three types of POXs in the upper intact leaves. Over the period of the experiment, enhanced activity of soluble POXs, correlated with the virus infection, was observed in both types of leaves of the susceptible cv. Igor. However, in resistant cv. Sante, the upper intact leaves of virus-inoculated plants showed a more intense but transient early response of soluble POXs. Part of a new POX gene was isolated from leaves of potato cv. Igor. A nucleotide sequence of 394 bp was determined and the abundance of the POX transcript was analysed by real-time PCR. There was no correlation between PVYNTN infection and the abundance of the transcript.

The power and delay of the proposed circuit are reduced when compared with existing design and energy consumption is also decreased.
Observable and Unobservable Involvement Behaviours of a Climatology Course’s Undergraduate Students

This study investigated students’ observable and unobservable involvement behaviours and their possible relation with academic achievement in a Climatology course at the Department of Physics and Astronomy of the Faculty of Sciences of the University of Porto, Portugal, in the Fall 2018/19. A structured online questionnaire titled “Observable and Unobservable Student Involvement Behaviours (OUSIB)” featuring a zero-centred 5-point Likert scale was used to collect the data. The OUSIB questionnaire comprised 20 multiple-choice questions, which were divided into two subscales: (1) Observable Involvement Behaviours; (2) Unobservable Involvement Behaviours; it was validated using Cronbach coefficient alpha. The collected data show that unobservable involvement behaviours are more frequent than the observable ones. This may reflect the difficulties that most students face in understanding the course contents, which likely triggers their introspective (unobservable) in detriment of their observable involvement behaviour. We notice that most of the Climatology syllabus consists of new subjects for which students generally have no prior knowledge or experience. It may constitute a great challenge for students being able to provide regular observable feedback during an entire problem-solving class. Moreover, there is a common tendency for high-grade students to prepare the classes in advance and involve less both observably and unobservably in classroom activities. We found no significant correlation between students’ final grades and their replies to the OUSIB questionnaire, which precludes any possible relationship between students’ academic achievement and their involvement behaviours in problem-solving classes.

Defining the differences in corporate culture in wood-processing and forest enterprises

Corporate culture represents a personality of a company. Suitable corporate culture should be a summary of behavior and action of the company as a whole and its individual employees on their way to achieving the strategic goals of the company. Using the Organizational Culture Assessment Instrument methodology, the corporate culture on a sample of 1,114 respondents in wood-processing and forest enterprises in Slovakia is defined and compared. The hypothesis that there were statistically significant differences between wood-processing and forest enterprises in individual components of corporate culture is confirmed in the paper. The differences in the perception of corporate culture in the area of organizational leadership and criteria of success can be considered the research output. In the area of organizational leadership, there are significant differences in the respondents’ opinions. In the area of criteria of success, employees of the wood-processing enterprises preferred the success of these companies based on the development of human resources and teamwork. There were no significant differences in the area of overall corporate culture. Both groups of employees preferred clan corporate culture.
Empirical study of cyanobacterial toxicity along a trophic gradient of lakes

A series of 22 lakes in southern Quebec spanning a wide trophic range were sampled to develop models of changes in cyanobacterial abundance and toxicity. All lakes contained toxic cyanobacteria, and epilimnetic toxin content, expressed as microcystin equivalents, was best predicted by total nitrogen concentration and total phosphorus concentration (TP). Although phytoplankton biomass increased linearly with increases in TP among lakes, toxigenic biomass increased as greater than the squared power of TP. The only potentially toxigenic genera whose biomass was correlated with microcystin concentration were Microcystis and Anabaena. Surprisingly, the best model for toxic-species biomass was based on epilimnetic nitrogen. The level of the hepatotoxin microcystin per unit biomass in these organisms did not vary markedly among lakes, supporting the idea that environmental factors control the occurrence, but have only a limited effect on the toxicity, of potentially toxic species.
Corona Virus Disease (COVID-19) Outbreak and the Strategy for Prevention

The Corona Virus Disease (COVID-19) is the novel disease of the respiratory system, causing the ongoing pandemic with flu-like symptoms. It is caused by a virus known as SARS-CoV-2 (Severe Acute Respiratory Syndrome Corona Virus-2). This disease affected the entire world and various myths are circulating about its diagnosis, treatment, and prevention. The choice for diagnosis should be based on clinical and epidemiological factors and linked to an assessment of the likelihood of infection. A number of rapid diagnostic and serological tests are being used for the detection of suspected COVID-19 cases. However, the sensitivity and specificity of such newly marketed tests have not been evaluated and never up to standard yet. Therefore, it is not recommended any such immunochromatographic or serological rapid screening tests for the diagnosis of SARS-CoV-2 infections. The most reliable diagnostic test to confirm COVID-19 is PCR (Polymerase Chain Reaction) which is a molecular-based test for the detection of SARS-CoV-2. Eradication of highly contagious SARS-CoV-2 Virus that causing the ongoing deadly pandemic COVID-19, demands individual attention and awareness are necessary regarding the route and mode of transmission across the bounders throughout the entire world. Proper hand-washing, staying at the home and maintaining the social distance are proved to the most effective preventive measures and are immediate solutions to save human beings from this unseen enemy.
A mathematical model for the study of lipid accumulation in oleaginous microorganisms. II. Study of cellular lipids of Mucor circinelloides during growth on a vegetable oil

Microbial oil production from fatty materials of animal or plant origin has been an object of research and industrial interest for many years. During the process of microbial growth/accumulation of fat reserves, the dominating phenomena that define the composition of endocellular fat are, first, the specific process of incorporation of substrate fatty acids into the microbial cell and, second, the endocellular changes of fatty acids defined by the enzymic capabilities of the microorganism. The fatty acids will either be degraded for growth needs or act as substrate of endocellular biotransformation processes, leading to concentration changes and production of "new" fatty acids which did not previously exist in the substrate. The purpose of the present work is to study the endocellular lipids of Mucor circinelloides CBS 172-27 grown on sunflower oil. The mathematical model, described in part I, was applied in order to investigate the following: a. Microorganism specificity in the incorporation of substrate fatty acids. b. Microorganism specificity in the degradation of fatty acids present in the reserve fat. c. Possibilities of endocellular biotransformations during the microbial growth. In conclusion, this work is aimed at developing a quantitative expression of parameters defining the lipid composition of fat reserves. The proposed mathematical model can be used not only for selection of microbial strains having specific enzymic potential but also for substrate selection.

ONCE AGAIN ABOUT THE PROBLEM “4/3”

It is shown that the problem "4/3" or the problem of electromagnetic mass has a strict solution only if the fields are instantaneous. This result is valid in both the classical and relativistic variants. The hypothesis of the existence of a physical ether is introduced, which allows us to explain the constancy of the speed of light in inertial reference systems and features of instantaneous action at a distance.
Wave disturbance on lakeshores and the within-lake distribution of Ontario's Atlantic coastal plain flora

Although water level fluctuations may explain the persistence of Atlantic coastal plain species in certain Georgian Bay lakes, they cannot explain the within-lake distribution of this flora. To test whether the within-lake distribution of these species was correlated with disturbance from waves, 25 transects were quantitatively sampled along an exposure gradient in Axe Lake, Ontario. The proportion of Atlantic coastal plain species in a transect increased significantly with exposure (p < 0.01). Total frequency of Atlantic coastal plain species reached a maximum at an intermediate level of exposure. Analysis of substrate samples showed that the exposure gradient is a multivariate gradient including not only biomass removal by waves, but sorting of the shoreline substrate. The coarse, nutrient poor sites on exposed shores may allow the persistence of Atlantic coastal plain species in at least two different ways. Their physiological tolerance limits may be narrowly specialized on exposed shorelines. Alternat.
