Authors: Straub J , Boškovic L , Bogatzky T , Dornbierer U 
Published: July 2022

Abstract
As fish farming is becoming more and more important worldwide, this ongoing project aims at the simulation and test-based analysis of highly stressed wire contacts, as they are found in off-shore fish farm cages in order to make them more reliable. The quasi-static tensile test of a wire mesh provides data for the construction of a finite element model to get a better understanding of the behavior of high-strength stainless steel from which the cages are made. Fatigue tests provide new insights that are used for an adjustment of the finite element model in order to predict the probability of possible damage caused by heavy mechanical loads (waves, storms, predators (sharks)).
Meshes Made by Deformational Cutting
Authors: Zubkov N 
Published: July 2022

Abstract
Deformational cutting can be used for manufacturing meshes. A metal or polymer sheet with a thickness of 0.2-0.8 mm is used as blanks when producing meshes. The sheet is tightened on a cylindrical fixture, then finned by the deformational cutting method on both sides without separating chips. The finning on the second side is made perpendicular or at an angle to the direction of fins on the first side. The cut depth at finning both sides of the sheet is more than half of its thickness, which ensures the connection of interfin gaps on the opposite sides of the sheet. On the lathe by the deformational cutting method from metal and polymer (PET, Teflon) sheets, samples of meshes with cells from 20 microns were obtained. Finning on the opposite sides of the sheet not in perpendicular directions leads to the possibility of mesh stretching. In this work, the two-sided finning of thin-sheet titanium blanks with different finning directions of the opposite sides and variation of deformational cutting parameters is studied. The analysis of the stretching mechanics for obtaining rhombic, hexagonal, and parallelogram shapes of cells is carried out. The range of finning pitches and crossing angles that ensure the stability of the deformational cutting process and mesh stretching is established. The shape of the cell is mainly influenced by the length of the fin connection obtained on the opposite sides of the sheet. Increasing the connection length with a decrease in the intersection angle leads to the transition of the cell shape from rhombic to hexagonal. A parallelogram cell obtained in stretching is characteristic of the fins of opposite sides with differences in bending strength.

Abstract
Micro-magnetic testing technology is capable of non-destructively evaluating the mechanical properties and residual stress in ferromagnetic components. In the applications of micro-magnetic testing technology, several types of magnetic signals, such as magnetic Barkhausen noise, incremental permeability, tangential magnetic field and eddy current, etc., are used to characterize the target properties (mechanical properties and residual stress). In this paper, a unique framework for multifunctional micro-magnetic sensor design is proposed. Accordingly, a multifunctional micro-magnetic instrument is developed. Intermittently superimposed magnetic fields of high (several kHz) and low frequencies (several Hz) are used for material magnetization. Combined magnetic sensors are employed to measure a total of five types of signals, including the magnetic Barkhausen noise, incremental permeability, eddy currents, tangential magnetic field and main flux. Especially, twisted-pair wiring was used for winding two identical sensing coils. One of the sensing coils is used for eddy current or incremental permeability detection and the rest one acts as a compensatory coil to suppress the strong mutual induction voltage in detection coil. The entire instrument is composed of a multi-channel signal generator, a power amplifier, signal processing circuits embedded into the multifunctional sensor and a four-channel signal acquisition device. The multi-channel signal generator is constructed based on FPGA and high speed D/A converters. The direct digital synthesizer and state machine are programed in FPGA to enable the excitation of intermittently superimposed signals of high and low frequencies. Carefully experiments were performed to test the performances of the developed instrument. The results obtained from different types of steels proved that the developed instrument can acquire five types of magnetic signals with high SNR. The features of the five types of magnetic signals can used to distinguish the material and its mechanical properties such as surface hardness.

Published: July 2022

Abstract
Most of existing researches related to ultrasonic machining on material removal mechanism are focused on single-grainultrasonic scratch and undeformed chip thickness. In this study for the rotary ultrasonic face milling (RUFM), two material removal modes of single and its adjacent abrasive grain with spindle speed were investigated. The impact and scratch with high-frequency vibration has been illustrated by the kinematic of multi-grain movement. We conducted the RUFM experiment to verify the proposed material removal modes. Experimental result shows that the high-frequency impact can increase surface roughness as undeformed chip thicknessdecrease, and high-frequency scratch can reduce the surface roughness as undeformed chip thickness turns up.

Abstract
The focus of this study is to see if Friction Stir Processing can improve the properties of an aluminium alloy with Boron Nitride (BN) particles on the surface. Friction Stir Processing (FSP) is a new surface alteration technique that uses friction to cause plastic deformation, resulting in grain refining and improved mechanical and surface properties. To process 2024 aluminium alloy plates, a straight cylinder tool was used under varying process parameters and to conduct tensile, hardness, wear and impact studies. The findings were evaluated in order to infer the significance of the process parameter and the reinforcement of the metal improvement properties. Friction Stir Processing was effectively processed by reinforcing the Boron Nitride plates and achieved significant changes in the mechanical and surface properties.

Abstract
Graphene has attracted a great attention in the recent years of research innovations mainly due to its unique properties and in particular, its structural composition of one-atom thick sheet of hexagonally arrayed sp2 carbon atoms. This article focuses on a method of synthesis of graphene oxide granules, which can be use as nanofiller in polymer matrix. Polymer nanocomposites reinforced with graphene nanofillers have better mechanical, thermal and electrical properties than pure polymer materials. Some corrugated spherical structures/granules of reduced graphene oxide were produced by a dispersion/drying method. For this purpose the reduced graphene oxide suspension produced in the laboratory by an improved method was mixed on a magnetic stirring and delivered by a peristaltic pump to the granulation zone at a speed 10-20 ml/min. The granulation zone temperature was kept within 40-150°C. The suspension was dispersed by compressed air up to 3 atmospheres. The produced granules were accumulated in a receiver, and dried in the vacuum oven to remove residues of solvents used in the process. The engineered reduced Graphene oxide were analyzed and the material structural-morphology was characterized by XRD, TGA, UV, Raman and SEM.
Problems of System Dynamics model development for complex product manufacturing process
Authors: Stadnicka D , Litwin P 
Published: July 2022

Abstract
Computer simulations are applied in enterprises for different purposes. They are used to support decision making at different levels of management. System Dynamics (SD) method is successfully used to model and simulate complex systems (including enterprises and manufacturing lines), but its applications are limited mostly to the policy and strategy level. This is due to the fact that SD approach assumes a low level of details and perceiving the system as a whole, and on the other hand, the reason may be the lack of examples of modelling manufacturing lines and workstations, at a higher level of detail. Based on a case study of a complex manufacturing system, this work presents examples of SD models of workstations and manufacturing line elements. Problems that were discussed in the frame of this paper are: process discretization, information flow with the use of kanban cards, processing of various components in one process, work of many employees at one workstation and assembly kit completion. The presented work may encourage researchers to use SD to model and simulate manufacturing lines at the operational level, and the presented solutions will be used in industrial practice to analyse and improve production systems.
Agent-based Modelling of Manufacturing Systems in the Context of “Industry 4.0”
Authors: Foit Krzysztof 
Published: July 2022

Abstract
The requirements of the modern market are manifested mainly in the need to provide a diversified assortment and personalized products. The ability to diversify the product range and adjust the production volume to the market requirements is a desirable feature of modern production systems. The Fourth Industrial Revolution has introduced many changes in the process planning domain that increased the possibility of better allocation of resources by applying artificial intelligence methods in order to achieve the effect of self-organization of the production process. The Smart Factory concept, based on cyber-physical systems, has allowed the customers to have greater influence on the process of manufacturing the ordered goods and even to change the order details during the process. The implementation of Industry 4.0 assumptions, and in particular the emergence of autonomous units, requires a new approach to modelling of manufacturing systems. This paper considers the problem of applying the agent-based modelling in modelling of such systems, focusing especially on the problem of adjusting the current formalism of agents or holons to the principles of Industry 4.0. An important part is the analysis of the agent definition in the context of manufacturing systems, in accordance with the available literature. The next step involves the discussion on the possibility of representing the Industry 4.0-compliant systems in terms of multi-agent paradigm.

Abstract
The ATLAS detector is set to undergo a substantial upgrade
termed the “Phase-II” upgrade during the Long-Shutdown in
preparation for the start of operation of the High Luminosity Large
Hadron Collider (HL-LHC). This paper describes the development and
implementation of the Phase-II upgrade low voltage power supply
transformer-coupled buck converter (Brick) test bench. A large
scale production of approximately 2048 finger low voltage power
supplies, with an identical output voltage, is set to be undertaken
in the year 2022. This production will culminate in the complete
replacement of the LVPS Brick V7.5.0 currently installed within the
Tile Calorimeter. Due to the location of the Bricks within the inner
barrel of the TileCal their reliability is of the utmost
importance. Therefore, the implementation of performance screening
will be implemented and will involve the testing and certification
of all Bricks produced. A custom test bench has been developed in
order to facilitate the above-mentioned testing. The test bench
described herein quantifies and logs the performance of an upgrade
Brick allowing for comparison with predefined performance metrics
before being approved and subsequently installed on-detector.

Abstract
Looking at the present scenario of world’s energy consumption and its dependency on fossil fuels, biodiesel has become a ray of hope as it is environmental friendly fuel derived from plant sources. In that context the present paper reports the study of physical properties of Mahua, Pongamia and Waste cooking oil blend for usage as biodiesels in engines. Each biodiesel has its own specific properties which need to be tested before running test on a engine. The physical properties such as kinematic viscosity, flash point, fire point, density, heating values and acid values are measured for MPW (Mahua 50%, Pongamia 30%, Waste Cooking Oil 20%), PWM (Pongamia 50%, Waste Cooking Oil 30%, Mahua 20%) and WMP (Waste Cooking Oil 50%, Mahua 30%, Pongamia 20%) compositions prepared on volume basis. This study discovered that WMP biodiesel physical properties match nearly to that of diesel fuel. It is the best alternative with moderate flash point temperature, fire point temperature, better thermal efficiency, density and acid value in comparison with MPW and PWM biodiesels.

Abstract
Woody biomass in Ukraine is currently seen as an important resource for securing development of national renewable energy sector, avoiding dependence on the imported fossil fuels, and for building a low-carbon economy. This research highlights the indices of the overall energy potential of Ukraine’s forests of the dominant tree species, expressed in units of primary energy. The indices are differentiated by biomass components and stand age groups. The information basis of the research consists of two main components: data on biometric assessment of trees collected at temporary sample plots, and mathematical models of biomass expansion factors. The research features the assessment results on the annual potential of woody biomass for stem wood (fuel wood), logging residues and wood processing residues. This resource forms a part of the sources of renewable energy and can be used for securing energy needs of the society. The proposed indices of woody biomass energy potential serve as an information basis for shaping the regional programs of forest bioenergy development in Ukraine.

Published: July 2022

AbstractLiveability interprets as making residents comfortable in their built environment. As daylighting becomes a necessity for human beings, daylight availability can improve the liveability of dwelling habitats, especially in high-density urban areas. Relayouting the building block without reducing the usable floor area can improve daylight availability. Kampung Braga is an example of how a heavy slum area has a low liveability quality and classifies into impoverished slum settlements at the stake of being resettled. The spatial arrangement becomes necessary to enhance the community’s quality of life. This article aims to examine how the intervention through urban layout can affect daylight availability to improve the liveability for kampung Braga. This research uses simulation methods with climate-based daylight modelling (CBDM) software to simulate daylighting with a dynamic approach. Rhinoceros for modelling, Honeybee for vertical sky component (VSC) simulation, and DIVA for daylight availability simulation. Based on the simulation on three alternative urban layouts in line with spatial plan context, it is shown that intervention through urban layout and typology of kampung Braga has shown better VSC and daylight availability values than the existing conditions. It is necessary to pay attention to the context of the building around the site when designing a specific building typology. Modifying configuration, floor height, model, and orientation show a better VSC reception and vertical facade illumination. City stakeholders need to be aware of the low liveability of the urban kampung. Planning the right urban plan design can improve daylighting availability and increase the liveability of the urban kampung.
Study on Daylight Performance and Spatial Configuration of Low-cost Apartment Building in Indonesia through Computational Simulation
Authors: Suryo Mahatma Sindu 
Published: July 2022

Abstract
Daylight is one of the variables in measuring the Indoor Environment Quality (IEQ) of buildings. Optimizing daylighting in design will benefit the health of building occupants and also potentially contribute to energy saving. Most of the low-cost apartment buildings have a problem in providing daylight for the habitable space. This paper investigates the daylight performance of low-cost apartment buildings based on the space configuration. This study used two bed-rooms low-cost apartments (36 square meters) as a simulation model. Three building types used in this simulation are 1) The general typology, 2) The government typology, and 3) The alternative typology. This study used DIALux 9.1 software to simulate the daylight performance in a Low-cost apartment building. The simulation results are analysed and compared with the natural lighting standard for the building (SNI 03-6575-2001). The study shows that the alternative building type provides the best daylight performance in terms of an average levels of illuminance and distribution.

Published: July 2022

Abstract
Standard brick walls have caused a gradual increase in the area’s temperature due to the bricks’ emissivity. Therefore, several effective technologies to overcome this problem have been proposed, one of which is thermal insulation by covering the outer walls of bricks from exposure to sunlight. This study compares thermal insulation effectiveness with Glass Fiber Reinforced Cement (GRC) and Expanded Polystyrene (EPS) material to obtain better insulations. This study is performed by modeling the area of 4 housing units using ENVI-met V4 in a humid tropical climate, focused in an east-west direction in a clear sky. Each building measures eight times 6 m2, with 4 meters in height, with a distance between buildings of 3 meters. GRC and EPS are affixed to the entire surface of the outer wall of the building, both on the east side and west sidewalls. The parameter observed is the wall surface temperature. The results showed that walls with GRC and EPS gave more effective results in lowering the surface temperature of brick walls, with values ranging from 8-23%. The use of insulation intervention on the east wall at 06.00-12.00 and the west wall at 13.00-18.00 shows higher accumulated surface temperature than the standard brick wall at peak hours, which means that the insulation material controls solar radiation. However, the phenomenon on the east wall at 12.00-07.00 and the west wall at 18.00-13.00 shows a controlled temperature above the surface temperature when using a standard brick wall.
Space Syntax Analysis on Sundanese Traditional Villages (Case Studies: Kampung Naga, Kampung Ciptagelar, and Kampung Dukuh)
Authors: Alfathani F , Nurdini A 
Published: July 2022

Abstract
This study is conducted to identify spatial patterns of traditional villages in Indonesia, especially the Sundanese traditional villages using the space syntax approach. The indicator of the spatial pattern was measured by the quality of circulation such as connectivity, integration, choice, mean depth, connectivity of visibility, and agent analysis. Kampung Naga, Kampung Ciptagelar, and Kampung Dukuh was purposively selected as case studies. The spatial maps from open-source literature were utilized for space syntax analysis. The scale of circulation quality was measured in a 0-5 scale, which was visualized by dark blue (very low) until red colour (very high) for the indicators. In general, all case studies have relatively low accessibility and very low choice and agent analysis indicators. This means those villages have an exclusive and private spatial pattern. In detail, Kampung Dukuh has relatively high connectivity, mean depth, and connectivity of visibility indicators than other case studies. It can also be influenced by the proximity of the village to the nearest town. Sundanese traditional villages have fairly segregated spatial, that is to conserve their norms, such as hierarchy and social status.
