Statistical Stability Analysis of Stationary Markov Models
Authors: Doronina Julia , Skatkov Aleksander 
Published: October 2019

An approach is proposed to assess the quality of stationary Markov models without absorbing states on the basis of a measure of statistical stability: the description is formulated and its properties are determined. It is shown that the estimates of statistical stability of models were raised by different authors, either as a methodological aspect of the model quality, or within the framework of other model properties. When solving practical problems of simulation, for example, based on Markov models, there is a pronounced problem of ensuring the dimension of the required samples. On the basis of the introduced formulations, a constructive approach to solving the problems of sample size optimization and statistical volatility analysis of the Markov model to the emerging anomalies with restrictions on the accuracy of the results is proposed, which ensures the required reliability and the exclusion of non-functional redundancy.
To analyze the type of transitions in the transition matrix, a measure of its divergence (normalized and centered) is introduced. This measure does not have the completeness of the description and is used as an illustrative characteristic of the models of a certain property. The estimation of the divergence of transition matrices can be useful in the study of models with high sensitivity of detection of the studied properties of objects. The key stages of the approach associated with the study of quasi-homogeneous models are formulated.
Quantitative estimates of statistical stability and statistical volatility of the model are proposed on the example of modeling a real technical object with failures, recovery and prevention. The effectiveness of the proposed approaches in solving the problem of statistical stability analysis in the problems of qualimetric analysis of quasi-homogeneous models of complex systems is shown. On the basis of the offered constructive approach the operational tool of decision-making on parametric and functional adjustment of difficult technical objects on long-term and short-term prospects is received.
Simulation Model of Electric Code-Modulated Signal in Russian Systems of Interval Control of Train Movement Based on Track Circuit
Authors: Prisukhina Ilona , Borisenko Dmitry , Lunev Sergey 
Published: October 2019

Systems of interval control of train movement Signaling systems, which are currently in service in Russian railways, use the electric track circuit as the main data channel between signals and locomotives. Code-modulated electric signals transferred through that channel are frequently get corrupted which leads to railway traffic delays.
Decoding of the electric signal received from a track circuit can be represented as an image classification problem, and thus the stability of the data channel could be significantly improved.
However, to build such a classifier based on some machine learning algorithm, one needs a large dataset. In this article, a simulation model to synthesize this dataset is proposed.
The structure of the computer model matches the main stages of the electric code-modulated signal generation in a track circuit: code signal generator, rails, locomotive receiver.
Based on code signal generator schematic and waveform diagrams, a generator algorithm is developed. At this stage, we modeled timings of electric code signals according to the specification as well as their random deviations caused by various factors.
The analysis of substitution circuits of the rail line revealed that it has the properties of a low-pass filter. So, the rail line using the Butterworth digital filter with corresponding parameters is modeled. Additionally, at this stage, random noise during transmission was taken into account.
A similar technique is applied for modeling of a locomotive receiver which has a band-pass filter as the first signal processing block.
Thus, the proposed simulation model consists of a set of algorithms which run in series. By varying the parameters of the model, one can synthesize waveform diagrams of the electric code-modulated signal received by the locomotive equipment from a track circuit working in various modes and conditions.

Aim. To assess the correlations between office and ambulatory blood pressure (BP) levels and some cardiovascular risk factors (RFs) in healthy young people and young people with BP dysregulation. Material and methods. In total, 234 male and female students of the Stavropol State Medical Academy were examined (73 men, 161 women; age 18-23 years, mean age 21,4±0,2 years). The standard questionnaire included items on family history and behavioural risk factors. The examination also included anthropometry, psychological symptom questionnaire survey, office BP measurement, and ambulatory BP monitoring. Results. RFs of cardiovascular disease (CVD) were widely prevalent in the students examined, with the rates in males being 2-3 times higher than in females. Arterial hypertension (AH) was presented by its labile forms – isolated office AH and masked AH. Participants with these AH forms, compared to healthy students, were characterized by a greater number and greater strength of the correlations between office or ambulatory BP parameters and some CVD RFs.Conclusion. The association between labile AH and leading CVD RFs in young people points to the need for regarding individuals with labile AH as a risk group and for optimising preventive programs in students.

Интегральное понимание как способ изучения предельных ориентаций: подход И. Ваха
Authors: Козлова Ирина Львовна 
Published: October 2019

<p>Статья представляет новую интерпретацию методологических условий интегрального понимания Иоахима Ваха (1898–1955). Проблематизация и актуализация осуществлена через рассмотрение ценностных ориентаций и религиозного опыта. Концепт «предельность» представлен в контексте аксиологической парадигмы с учетом религиозного фактора. Предложен термин «предельная ориентация». Сделан прогноз о том, что концептуальная модель интегрального понимания, основанная на методологических условиях И. Ваха, может быть продуктивно использована современной наукой в междисциплинарных исследованиях.</p><p>Термин «предельная ориентация» является логическим произведением понятий «религиозная ориентация» и «ценностная ориентация». Предельная ориентация — это состояние тотальной устремленности человека к предельной реальности. Предлагаемый концепт фокусируется на субъективной стороне предельного опыта и может быть использован в религиоведении, социологии, психологии и культурологии.</p><p>Интегральное понимание акцентирует внимание на трех базовых феноменах: индивидуальность, сущность ценностного и значимость свободы. Интегральное понимание включает четыре основные компетенции. Первая — это понимание общих предельных смыслов, выраженных в разных языках. Вторая — это умение пользоваться эмоциональным интеллектом. Третья — это способность настроить волю на конструктивную цель. Четвертая — это практический опыт работы с человеческим материалом.</p>

Una mirada al desarrollo de aditivos reductores de viscosidad y sus aplicaciones en el transporte de crudos pesados
Authors: Remolina Campos Sergio Arturo , Luna Cáceres César Augusto , Espitia Castellanos Jaime , Patiño Reyes Édgar Javier 
Published: October 2019

La presente revisión aborda la problemática que presentan los crudos pesados debido a su alta viscosidad, lo cual dificulta su transporte por tubería y su directa relación con la fracción de asfaltenos, cuyo apilamiento genera cambios en la reología del crudo, altas caídas de presión y mayores requerimientos energéticos en el bombeo, e incluso taponamiento de tuberías. Las investigaciones reportadas se han enfocado en predecir y elucidar la composición estructural de los asfaltenos, de lo cual se resaltan modelos que describen a los asfaltenos como sistemas de anillos aromáticos policondensados, que pueden unirse por interacciones de Van der Waals formando agregados, o también como estructuras jerárquicas de sistemas de anillos de hidrocarburos aromáticos policíclicos (PAH), que finalizan en la formación de racimos (clúster). También se resalta el modelo termodinámico coloidal, el cual predice moléculas de asfaltenos suspendidas en una fase líquida, estabilizada por resinas adsorbidas en su superficie.
Una alternativa para disminuir la viscosidad de los crudos es la inclusión de aditivos, los cuales mediante interacciones moleculares apropiadas, generan la dispersión de agregados asfalténicos, reflejándose en la disminución de la viscosidad. Por ello a la hora de diseñar aditivos reductores de viscosidad pare crudos, es importante diseñar estructuras moleculares con determinados grupos funcionales asociados a aminas, amidas, alcoholes, ácidos, entre otros, que favorezcan interacciones que generen la dispersión de asfaltenos. Por ellos y con el fin de brindar un panorama amplio de esta línea de investigación tan extensa, se finaliza este documento con una revisión de algunos aditivos reductores de viscosidad, implementados por diferentes investigadores.
