Growth and Deformation Simulation of Aluminum Bronze Grains Produced by Electron Beam Additive Manufacturing

When working out 3D building-up modes, it is necessary to predict the material properties of the resulting products. For this purpose, the crystallography of aluminum bronze grains after electron beam melting has been studied by EBSD analysis methods. To estimate the possibility of sample form changes by pressure treatment, we simulated structural changes by the method of molecular dynamics during deformation by compression of individual grains of established growth orientations. The analysis was carried out for free lateral faces and grain deformation in confined conditions. Simulation and experiments on single crystals with free lateral faces revealed the occurrence of stepwise deformation in different parts of the crystal and its division into deformation domains. Each domain is characterized by a shear along a certain slip system with the maximum Schmidt factor. Blocking the shear towards the lateral faces leads to selectivity of the shear along the slip systems that provide the required shape change. Based on the simulation results, the relationship between stress–strain curves and structural characteristics is traced. A higher degree of strain hardening and a higher density of defects were found upon deformation in confined conditions. The deformation of the columnar grains of the built material occurs agreed with the systems with the maximum Schmidt factor.

De afbakening, delen en opbouw van Exodus 19:1–31:18

The Delimitation, Partition and Structure of Exodus 19:1–31:18 Many scholars consider Exodus 19–24 the first great story unit of the last complex of Exodus (19:1–40:38). Concerning this story unit there are three problems: (1) the delimitation, (2) the partition, and (3) the structure of this story unit. Firstly, Exodus 19:1 may form the beginning of the story unit, 19:1 is also the final clause of Exodus 18:1–27. A lot of commentators consider 24:18 the end of this story unit. I, however, argue that there is more reason to see 31:18 as the end. Secondly, the partition of the story units after the introduction (19:1–2c). The reader can distinguish three time-units: (a) 19:2d–8c+19:8d–15; (b) 19:16–20:20+20:21–24:4a; (c) 24:4b–31:18. Thirdly, the structure of Exodus 19:1–31:18 is as follows: 19:1–2c (exposition); A 19:2d–8c (programmatic oracle) + 19:8d–15 (announcement of the coming and descent of Jhwh) → B 19:16–20:20 (coming and descent of Jhwh); A’ 20:21–24:4a (working out of the promised future in the programmatic oracle); B’ 24:4b–31:18 (oracle for the institution of the cultus, in which Jhwh can come).

Experimental studies of the formation of zones resulted from air flow around a system of model buildings

This paper presents the results of working out the methodology for conducting experimental studies of the flow around the objects modeling the urban environmental conditions. The experiments were conducted in the wind tunnel of the Siberian Federal University. Two objects of different heights imitating buildings were considered the models. Special attention was paid to the study of the flow pattern at the tandem arrangement of model buildings. Visualizing the flow, the low-velocity and high-velocity zones, as well as recirculation areas were identified. At that, these zones had their peculiarities in terms of the direction of flow twisting behind each object. The study allowed revealing that the vortices separating from the edges of the studied objects play a special role in the flow formation.

APPLICATION OF THE APPROACH TO CREATE AN INFORMATION CONSTRUCTION MODEL AT THE PRE-DESIGN STAGE OF INVESTMENT AND CONSTRUCTION PROJECTS

At the present stage of development of the construction industry, steps to improve the efficiency of investment and construction projects can no longer be considered outside the context of construction information modeling technologies. Today, one of the main criteria for optimizing work on investment and construction projects is to reduce the time spent searching, working out and agreeing on spatial, financial, and temporal information about the construction object, therefore, the issue of the correct organization of information modeling of a construction site is quite relevant. In most cases, the design assignment is drawn up in the form given in Appendix B DBN A 2.2-2-2014 and is formal in nature. The presence of a design assignment, drawn up using the tools proposed below, reflects the thoroughness of the customer's elaboration of an investment and construction project, and reduces the risks of its implementation. The proposed methodology is based on three components of counter design, such as disaggregation, aggregation, and decomposition, from which its name – DAD –approach comes from. Allocation of structural elements in the structure of a building by disaggregation (analysis of alternative options) allows to create its model in the form of a hierarchical structure consisting of detailed and mutually synchronized parts - the configuration of the building. In accordance with the configuration of the construction site, hierarchical numbering is further reflected at all stages of design and in all its sections, incl. stamps of drawings and local estimates. This creates a unified system of interconnection and control of project sections. The creation of a construction site configuration in the form of a tree model with hierarchically numbered elements at the pre-design stage allows it to be applied at subsequent stages of the life cycle of a construction object in information modeling technologies. The use of the DAD – approach in counter-design is intended to increase the efficiency of the implementation of investment and construction projects.

Internet of Things Monitoring System of a Modeled Cleanroom

The development of a cleanroom monitoring system needs more concentrated consideration consistently. There is a challenge to prove that the cleanroom operates following the specifications, in other words, users do not see the software error, they see failures in execution. This paper aims to design a smart monitoring system to monitor important parameters inside the cleanroom, i.e. temperature, humidity, and pressure to produce a good quality of work or experiment inside the cleanroom. The observing framework utilizes Arduino Mega as a microcontroller, ESP 8266 Wi-Fi module, DHT 11 as an integrated temperature and humidity sensor, HX710B as a pressure sensor, and Blynk application as a monitoring system to record and show information including provide fault notification. The project is tested on a modeled cleanroom to monitor important parameters via smartphone anytime and anywhere. From the experimental results, the Cleanroom IoT Monitoring System successfully read all parameters based on the system requirements and displays data of parameters in real-time and stored historical data. This system is also successful to provide failures notification of humidity, temperature, and pressure in real-time if any of the parameters are out of range from the system requirements. Lastly, users can monitor the condition of the cleanroom anytime and anywhere including receiving real-time failures notifications. This concept can avoid or reduce cleanroom working out of the criteria that can cause testing or experiment inside the cleanroom to be inaccurate. By observing and controlling the prerequisite development for IoT monitoring systems, great nature and better quality of performance of operational cleanrooms can be delivered.
