Published: October 2022

In the middle of the 20th century, television technologies found their application in various fields of medical science and practice, in particular in instrumental diagnostics and radiology. Interactive teleconferences have become the technical basis for distant consultations (medical videoconferencing). The emergence of two-way exchange of video and audio information in real time preceded by the period of one-way television communication (so-called «medical television»). Objective: to identify, systematize and comparatively study the patterns of development of scientific and practical knowledge related to the use of one-way television technologies in medicine. The «medical television» used in medicine in the period of 1930-1960s to organize closed (non-public) broadcasts for educational purposes. The use of «medical television» in European countries was discrete. In the United States, the use of «medical television» was purely applied, but it was very large-scale. Television broadcasts have become an indispensable component of professional conferences and congresses. In the USSR, the scientific and technical development of «medical television» followed the path of intrahospital broadcasts only. A distinctive feature was a number of development and research works in the 1950s-1960s for creation of specialized television equipment and the scientific substantiation of the requirements for the parameters of the broadcast image. Developed equipment was mass-produced. The technologies of «medical television» were introduce into the activities of medical educational institutions for the routine teaching of surgical disciplines in the USSR, USA, Great Britain, France, etc.

Modeling the dynamics of production of hard-to-recover oil depending on production and price parameters
Authors: Tarkhova А. Е. , Nemov V. Y.
Published: October 2022

The article examines the dynamics of production of hard-to-recover oil. A mathematical model describing the dynamics of oil production in the United States is constructed. The model is based on the equation of production capacity and its modification for the oil and gas industry. By analyzing the periods of 5 years, starting from 2008, the dependence of the desired values on various parameters was established. The main parameter included in the constructed differential model was the price of WTI crude oil. For the convenience of analysis, based on the EIA tabular data, we have accepted the price of conventional oil as a constant. The time lag of economic indicators was also taken into account, the optimal value of which was established using the linear regression method. Thus, taking into account all the revealed dependencies and the selection of empirical constants, a differential equation with a lagging argument was obtained. As a result of the consideration of cases, an analytical solution was constructed describing the dynamics of shale oil production, which allows it to be used to predict the parameters of the oil market.

Authors: Vasendin D. V.
Published: October 2022

Pesticides have been widely used to control weeds, diseases and pests of cultivated plants all over the world, mainly since the mid-twentieth century. Pesticides are very widely used for pest control in many countries. The persistent nature of most synthetic pesticides causes serious environmental problems. Decontamination of these dangerous chemicals is very important. This review paper examines the potential of various biological agents in the disinfection of agricultural soils. The fields of agricultural crops are polluted by the periodic use of pesticides. Biodegradation is an eco-friendly, economical, highly effective approach compared to expensive and environmentally hazardous physical and chemical methods. Biodegradation is sensitive to the concentration levels of hydrogen peroxide and nitrogen, as well as to changes in the microbial community, temperature and acidity. Experimental work for optimal conditions on a laboratory scale can give very fruitful results about specific strains of bacteria and fungi. This study revealed the advantage of bioremediation over physico-chemical approaches. Further research should be conducted to understand the mechanisms of biotransformation.

ABSTRACT
To support fertile agricultural land, a watering process is needed so that the water content in the soil is maintained. Watering activities carried out manually require a lot of energy. In addition, the water content given by manual watering cannot be measured accurately. In this paper, we propose automatic watering with a three-axis Cartesian robot for land with a size of 3 meters x 1.5 meters with 171 planting points. Fuzzy based watering control so that the water content given can be accurate. Before watering, the average soil moisture on the land was 45.28% with a minimum value of 40%, a maximum value of 50%. The target soil moisture for each point is 60%. The robot can water the entire planting point without human intervention. The average water content value of watering is 62.10%, with a minimum value of 60%, a maximum value of 65%. In addition, also compared with the application error with the fuzzy method with the on-offmethod, the fuzzy method is able to produce more accurate watering with an average error rate of 2.10%, while the on-off method has an average error of 5.32% against the soil moisture target. The fuzzy method is also more time efficient in watering, which is 7 seconds to 8 seconds, while the on-off method requires a watering time of 10 seconds to 15 seconds.

ABSTRACT
In ordering food at food courts, sometimes some difficulties cause too many delays in the food delivery process. Among them is the problem of identifying the customer who collected, the position of the orderer, and the length of the process. For example, in ordering food using a conventional system, the waiter must shout the customer's name to find a place to call. The food court ordering system consists of several stages, from choosing a shop to ordering drinks or food until the food is ready to be served. This study created an intelligent food court ordering system using a QR code and an android application. For customer orders, they must scan the QR code and select the shop, food and drink to be ordered. After being paid, the collected data in the form of food, drinks, customer names and table numbers will be sent to each shop to be processed and after the order has been prepared, the system will send a notification to the waiter so that the waiter immediately delivers the order to the customer. The system is made using supporting software, namely modular. To detect orders that have been prepared using the HC-SR04 sensor, esp8266 wifi module, and buzzer. The order and notification will then be sent to the firebase database and displayed on the web application at the checkout.
Modelling particle degradation and intermediate dynamics in a dispersed activated sludge microcosm
Authors: Ravndal Kristin T. , Kommedal Roald
Published: October 2022

Municipal wastewater consists of a large fraction of particulate organic matter. During biological wastewater treatment these particles undergo extracellular depolymerisation before products are taken up by bacteria (MW < 0.6 kDa). Particle degradation and intermediate formation dynamics is important in process analysis of wastewater treatment as the transport regime differ. This work aims to develop a model for particle degradation that includes intermediate dynamics as observed in experimental work. A model for particle degradation including intermediate dynamics, bacterial growth and endogenous respiration is proposed. Particle hydrolysis was modelled using the particle breakup model. Depolymerisation products were separated into five different size groups: colloids; high, medium and low molecular weight (HMW, MMW and LMW) polymers; and one fraction for oligomers and monomers (SB). Depolymerisation of colloids, HMW and MMW polymers was modelled using first order kinetics. LMW polymer degradation was modelled using Michaelis-Menten kinetics, while growth was based on traditional Monod kinetics and endogenous respiration followed ASM3. The proposed model was implemented in AQUASIM for a batch reactor system, and parameter estimation by LSE fitting to experimental data on particulate starch degradation over 117 days in a dispersed biomass microcosm was performed. Validation of the model against experimental data gave a very good fit to the PBM. The intermediate dynamics seen in the experimental data was also qualitatively demonstrated by the model, with accumulation of HMW, MMW and LMW polymers in the bulk liquid. However, the accumulation of monomers and oligomers in the bulk liquid could not be reproduced in the suspended growth model proposed. Hence, a structured biomass model (biofilm) is suggested for future work.

Authors: Manoranjan Luxshan , Winkler Dietmar
Published: October 2022

With the introduction of unregulated renewable energy such as wind, solar and tidal power, the operation of the electrical grid has become more and more challenging. The more dynamic production pattern requires more advanced control algorithms in order to maintain an acceptable voltage quality which is within the limits given by the electrical network regulators. Better tooling and improved simulation of different operation scenarios is required.This paper presents the development of voltage droop/compensation controller as used in a typical hydro power controller. The controllers has been implemented using the Modelica language and are according to the Norwegian Energy Regulatory Authority (NERA). Having the controller available in Modelica makes it possible to integrate them with hydro power system models build with the use of OpenHPL. The behaviour of the controller have been tested against a verified generator model of the OpenIPSL.
Control strategies preventing wastewater overflow in Oslo
Authors: Seyhan M. Halid , Komulainen Tiina M.
Published: October 2022

As climate change intensifies storms, larger rainwater volumes load the sewage network systems above the design capacity and escalate the risk of combined sewer wastewater overflow to natural waterways. Accordingly, the control challenge is to prevent the combined sewer overflow by adjusting the manipulated variables, such as pumps and gates, in the sewage network system. The aim of this study is to (1) compare traditional and predictive control strategies to four different storm scenarios, and to (2) quantify the preventive effect of these control strategies on wastewater overflow. The case study is applied in the Oslo combined sewage network system. Control strategies applying feedforward strategy minimize the overflow within the constraints of the sewer infrastructure. Compared to no control, applying feedforward-feedback control strategy decreases overflow to natural water ways by 21- 88% in different rain scenarios. Compared to feedback control strategy, the feedforward-feedback strategy can decrease overflow by 3--9%.
Simulation of the Effect of Local Electric Potential and Substrate Concentration on CO2 Reduction via Microbial Electrosynthesis
Authors: Ahmadi Vafa , Dinamarca Carlos
Published: October 2022

Integrating anaerobic digestion into electrochemical reactors is an advanced technology for biomethane recovery. Imposing low electric potential between electrodes, supplies CO2, electrons, and hydronium ions from anodic oxidation of organic and/or inorganic compounds. Then, autotrophic methanogens on the cathode produce methane from CO2 and H+ by electron uptake from the cathode. However, in mixed microbial environments, acetogens produce acetate as well. These reactions can take place via two different mechanisms, DIET (direct interspecies electron transfer) or IMET (indirect mediated electron transfer). This work investigates CO2 conversion to acetate and methane in an electrochemical biofilm reactor comparing the efficiency of CO2 reduction via DIET and IMET mechanisms at hydrogen evolving potentials from -0.3 to -0.7 vs SHE. The other goal is to prove the importance of mass balance in CO2 reduction at applied voltages. Simulations are done in AQUASIM version 2.1. Simulation results depicted that higher H+ concentration at -0.7 V vs SHE can reduce more CO2 in DIET with less current generation compared to IMET. This shows DIET the more efficient mechanism. Methane production is dominant in IMET model, however higher current is needed for CO2 fixation in this mechanism. Also, biomass concentration, acetate and methane production, substrate concentration, biofilm thickness, biomass distribution in biofilm, and current density over time in both mechanisms are investigated at variant voltages and substrate concentrations. Simulations showed that at high CO2 levels in both mechanisms CO2 conversion cannot reach maximum if the voltage is not high enough to supply H+.

Published: October 2022

Sulphide (H2S, HS- and S2-) is an undesired by-product of biogas production processes. This modelling work in Aquasim was carried out to study three parallel processes related to sulphide in AD processes: 1) H2S liquid-gas mass transfer; 2) Acid-base equilibrium; and 3) Sulphide oxidation with three different electron acceptors; nitrate, oxygen, and a biotic anode with a given potential. Multiplicative Monod (biotic processes) and Nernst-Monod kinetics (bioelectrochemical process) provide the basis for the sulphide bio-oxidation processes. At the current stage, the model can be used to study sulphide bio-oxidation and the effect of relevant parameters, including initial biomass concentration, uptake rates, temperature, and pH. The model can be improved further by implementing anaerobic microbial processes as competing reactions. With the proposed improvements, the model can be a useful tool for calculating the chemical dosage or electrode potential required for sulphide removal. These calculations can be based on both the concentration of H2S(g) in the headspace (ppm) often available at full-scale plants and the concentration of sulphide (HS-(liq)) in effluent streams from the plants.

Published: October 2022

Ethylene is the most produced organic substance in the world and is a pillar in the chemical process industry. The production pathway is energy intensive and has a corresponding high carbon footprint. This work explores, simulates, and presents the possibility of reforming the fuel gas of a steam cracking furnace. Currently, methane (CH4) and hydrogen (H2) from the cracking furnace outlet makes up the fuel source. If H2 produced by reformation of the current fuel can cover the energy demand of the steam cracking furnace, it can drastically reduce the CO2 emissions.
LSTM-based PSS Design for Modern Power Systems
Authors: Aleikish Khaled , Øyvang Thomas
Published: October 2022

With the ever-increasing incorporation of wind and solar power in the electric power system, enhanced performance of classical bulk hydropower plants for robust operation of the power system is required. This current energy transition may cause a rapid increase in undesirable low-frequency oscillations (LFOs) in modern power system operations. A power system stabilizer (PSS) located at hydropower plants is one solution to damp such oscillations. This paper presents a new method based on Long Short-Term Memory (LSTM) neural networks for sine-wave phase shifting to possibly enhance PSS damping. The proposed controller considers the PSS input and the rotor speed deviation as a damped sinusoidal signal, simplifying PSS control and real-time optimization of PSSs parameters. Results show that the proposed LSTM architecture is able to learn multiple damped sine waves with different frequencies and decay rates. Therefore, the proposed controller can operate on the entire range of LFOs, unlike simple feedforward neural network (FNN) controllers, which can only learn and function on a single LFO frequency.

Published: October 2022

Air-assist atomizers have been widely used in various applications such as the aerospace industry, internal combustion engines, molten metal, food processing, etc. The mean drop size for these atomizers was obtained through the Shadowgraph imaging technique. This study aims to assess the feasibility of the acoustic chemometrics approach for classifying the atomizer types and predicting the mean drop size, such as Sauter mean diameter (SMD), for a two-phase spray atomizer employed. The droplet size measurements were carried out at three radial locations and one axial location for various air and liquid (water) flow rates. The acoustic signals were recorded through two different sensors: accelerometers and microphones. The main objective of this work is to implement prediction models for the mean drop sizes (SMD) measured at various locations. The model prediction is based on the dimensionless number B, whose unique values correspond to different two-phase flow working conditions. This analysis will further cater to the question that whether the acoustics chemometrics approach, including Principal Component Analysis (PCA) and Partial Least Squares Regression (PLS-R), is suitable for extracting valuable information such as predicting mean drop size (SMD) in two-phase flows through recorded acoustic signals.
Evaluating the acceptability and accuracy of Phasepy as a Phyton framework to calculate the interfacial properties and phase equilibrium

Published: October 2022

Phasepy is a scientifically defined open-source package in python for computational thermodynamics. Phasepy indeed calculates the interfacial properties and fluid phases equilibrium using an equation of state. In addition, Phasepy enables the scientists to optimize the relevant parameters to the equilibrium of multicomponent vapor-liquid, liquid-liquid, or vapor-liquid-liquid mixtures. The Phasepy can model the equilibrium in the continuous approach (combining a cubic equation of state and a mixing rule) or the discontinuous approach (using a virial equation and an activity coefficient model). So, this study is to develop a code in a continuous approach using a combination of Soave-Redlich-Kwong (SRK) or Peng Robinson (PR) as the equation of state and quadratic mixing rule (QMR) and modified-Huron-Vidal mixing rule (MHV) as the mixing Rule. Although the algorithm of the developed model is new, it is tried to utilize the predefined function of Phasepy to calculate fluid phase equilibrium and interfacial properties. In fact, the five well-performed previous experimental studies are modeled using Phasepy, and in the following, the outputs of the developed models are compared with the relevant experimental results. The bubble point features, dew point features, liquid and gas composition, and density of multicomponent mixtures are considered parameters in this extended study to evaluate the accuracy of the Phasepy function based on experimental results.

Published: October 2022

Organic Rankine cycles (ORC) are efficient technologies for waste heat recovery (WHR) at low to mid temperatures. For the design of ORC power cycles, several thermodynamic parameters should be considered. A challenge related to small scale (<50 kW) ORC cycles is to define the optimal process given frequent variability in a heat source. Many relevant applications require robust ORC systems to perform under varying heat source loads. This is an area where the body of knowledge must be further developed.In this work, the design of small-scale ORC cycles with varying heat source conditions is addressed by means of system modelling, simulation, and optimization. A framework is presented that consists of multi-scale optimization for the design of small-scale ORC systems considering seasonal and hourly heat source variations. The framework is developed as a flexible tool allowing to include fit-for-purpose models of key elements of the cycle, such as expander and heat exchanger, to suitably simulate off-design performance.The optimization framework has been tested on a case study representing a woodchips-fired micro-cogeneration unit via ORC. The case study is representative of an existing unit operating at the Czech Technical University (CTU) in Prague. The results indicate that the tool delivers an ORC design that has a 5 % larger accumulated power production with the hourly variation of the heat source during one year than the original ORC solely optimized at the design heat source condition. The optimal ORC system also shows a 33 % smaller nominal capacity and size of heat exchangers than the ORC at the reference design, indicating a potential reduction in the capital cost.
