The aim of this study is to reconnoitering the possibility of using ultrasound for a continuous and non-invasive measurement of the arteries parietal rheology. In this work, a sensor of ultrasound is used to measure the movement and the speed of the carotid artery wall, an image of the arteries parietal rheology.

Advanced control strategies for continuous capture of monoclonal antibodies based upon biolayer interferometry.

The semi and fully continuous production of monoclonal antibodies (mAbs) has been gaining traction as a lower cost, and efficient production of mAbs to broaden patient access. To be truly flexible and adaptive to process demands, the industry has lacked sufficient advanced control strategies. The variation of the upstream product concentration typically cannot be handled by the downstream capture step, which is configured for a constant feed concentration and fixed binding capacity. This inflexibility leads to losses of efficiency and product yield. This study shows that these challenges can be overcome by a novel advanced control strategy concept that includes dynamic control throughout a perfusion bioreactor, with cell retention by alternating tangential flow, integrated with simulated moving bed (SMB) multi-column chromatography. The automation workflow and advanced control strategy were implemented through the use of a visual programming development environment. This enabled dynamic flow control across the upstream and downstream process integrated with a dynamic column loading of the SMB. A sensor prototype, based on continuous biolayer interferometry measurements was applied to detect mAb breakthrough within the last column flow-through to manage column switching. This novel approach provided higher specificity and lower background signal compared to commonly used spectroscopy methods, resulting in an optimized resin utilization while simultaneously avoiding product loss. The dynamic loading was found to provide a twofold increase of the mAb concentration in the eluate compared to a conservative approach with a predefined recipe with similar impurity removal. This concept shows that advanced control strategies can lead to significant process efficiency and yield improvement.

Sensor Mathematical Model Data Fusion Biobjective Optimization

Sensors are an important tool to quantify the changes and an important part of the information acquisition system; the performance and accuracy of sensors are more strictly desired. In this paper, a highly sensitive fiber optic sensor for measuring temperature and refractive index is prepared by using femtosecond laser micromachining technology and fiber fusion technology. The multimode fiber is first spliced together with single-mode fiber in a positive pair, and then, the multimode fiber is perforated using a femtosecond laser. The incorporation of data model sensors has led to a rapid increase in the development and application of sensors as well. Based on the design concept and technical approach of the wireless sensor network system, a general development plan of the indoor environmental monitoring system is proposed, including the system architecture and functional definition, wireless communication protocols, and design methods of node applications. The sensor has obvious advantages over traditional electrical sensors; the sensor is resistant to electromagnetic interference, electrical insulation, corrosion resistance, low loss, small size, high accuracy, and other advantages. The upper computer program of the indoor environment monitoring system was developed in a Visual Studio development environment using C# language to implement the monitoring, display, and alarm functions of the indoor environment monitoring system network. The sensor-data model interfusion with each other for mutual integration performs the demonstration of the application.

ИНТЕРФЕЙСНОЕ ВЗАИМОДЕЙСТВИЕ BIM ПРОГРАММЫ С MS OFFICE

The paper examines the necessity and possibility of interface interaction of the information modeling program Revit Autodesk with the common office program MS Excel. Such interaction makes it easier to prepare project documentation in accordance with the requirements of Russian standards, GOST. An analysis of the capabilities of the built-in Revit tools for creating specifications and their design according to GOST requirements showed an insufficient level of automation of these processes. Ready-made foreign and Russian solutions in the field of Revit plugins that implement interaction with Excel have a number of disadvantages. The purpose of this article is to demonstrate the capabilities of the application programming interface (API) for creating applications using the example of a developed software solution for automating the unloading of information from a BIM model into an Excel electronic document, in order to bring data presentation standards in line with GOST requirements. The application is developed using a tool environment: the C# programming language, the MS Visual Studio development environment, the WPF user interface creation tool, the Revit-side application programming interface .Net API, an interface for interacting with Excel ClosedXML files. As a result, the interface of the developed plugin is presented. The program allows you to export documents-statements and specifications - to Excel, designed according to the requirements of GOST. The user-friendly tab-based user interface, the compliance of the program design with the Revit system and the implemented functionality give the program advantages over its analogues. The application is available for free download to any Revit user, which is of practical importance.

Custom application of PCS software development platform on EAST

The plasma control system software development platform (PCS-SDP) will provide an effective, convenient, and visual development environment for PCS software developers. The detailed design of PCS-SDP for the Chinese fusion engineering testing reactor has been completed. A custom application of PCS-SDP is implemented on EAST to verify its effectiveness and reliability, and validate the platform architecture and technical proposal. PCS-SDP customizes components corresponding to the algorithm control interface. Developers can directly drag and drop the components to design data structure, waveform information, and other parameters of the algorithm required for communication with the GUI interface. Moreover, the algorithm logic master file, including the basic modules and functions, is predefined in the platform. Developers only need to add the algorithm logic code to the corresponding module and then save the project. The new algorithm can be compiled, linked with other files, and finally successfully integrated into PCS. Therefore, PCS algorithm development becomes more intuitive and efficient.

A study on VAL platform for 5G network for large-capacity data transmission

Recently, a lot of researches have been conducted on a platform that provides a Visual Programming development environment capable of 3D editing and interactive editing in an In-VR (Virtual Reality) environment so that VR/AR (Augmented Reality) contents can be quickly worked on. In this paper, a functional language-based VR/AR specialized language(VAL) and Visual Language were developed, and VR/AR prototypes were easily implemented using these languages on the platform. Then, prototypes based on the 5G network can be shared and collaborated with others, and content creation can be continued in Unity and Unreal without interruption. In addition, this paper shows the recognition process for users, the PS/CS check process and the node processing process for transmitting content by limiting the process for transmitting VAL-based mass data in 5G environment. The proposed platform can easily create a prototype of their intended VR/AR App (or content) even for users (beginners) who do not have a certain level of knowledge and experience in 3D graphics and software coding, and share it with others. It has characteristics that can be done. Consequently, we propose a method to use VAL more effectively in a 5G environment.

A study on eye-tracking-based Interface for VR/AR education platform

In recent years, a platform providing a Visual Programming development environment capable of 3D editing and interaction editing in an In-VR environment to quickly prototype VR/AR contents for education of VR and AR for general users and children. In the past, VR contents were mostly viewed by users. However, thanks to the rapid development of recent computing technologies, VR contents interacting with users have emerged as a device capable of tracking user behavior in a small size It was able to appear. In addition, because VR is extended to AR and MR, it can be used in all three virtual environments and requires efficient user interface (UI). In this paper, we propose UI based on eye tracking. Eye-tracking-based UI not only reduces the amount of time the user directly manipulates the controller, but also dramatically lowers the time spent on simple operations, while reducing the need for a dedicated controller by allowing multiple types of controllers to be used in combination.

Vapor–Gas Mixture Condensation in Tubes

A one-dimensional differential model describing condensation of a vapor–gas mixture in tubes and its implementation on a computer in the Visual Basic integrated development environment is presented. The model is intended for studying the operation conditions and parameters of the relevant types of condensing devices and, in the future, for carrying out technical computations and providing information support to design developments and tests. The compute kernel is based on mathematical models that take into account the main significant effects during condensation, such as gravitation (with different tube orientations), friction at the phase interface boundary (taking into account the cross flow of mass and specific roughness of the boundary), availability of noncondensing, admixtures, different external cooling methods, and the possibility of dangerous operation conditions to occur (freezing and flooding). The well-studied limiting models, such as a gravity or shear condensate film, are united by the interpolation method between asymptotes. The mathematical formulation of the problem consists of conservation equations (of momentum, energy, and mass of mixture components) for averaged flows of coolants supplemented with algebraic relations for local coefficients of heat transfer, mass transfer, and friction at the interface boundaries. The remoteness of working fluid thermodynamic parameters from the critical point, which is almost always observed in condensing installations, is the natural limitation of the analysis model’s application field. A special analysis for determining heat transfer and friction in gravity–shear condensate films based on an adequate differential turbulence model is carried out.

The development of Messenger bots for teaching and learning and accounting students’ experience of the use thereof

AbstractThis study reports on the development of two Messenger bots, designed to facilitate the learning of introductory and intermediate accounting. The Messenger bots were developed using a visual development environment that requires no coding knowledge. A thick description of the development of the Messenger bots is provided to encourage replication. It is submitted that instructors, rather than programmers, should take ownership of developing Messenger bots for teaching and learning. Preliminary exploration of the students’ satisfaction yielded positive results. Suggestions are made for specific applications of Messenger bots in teaching and learning and for further research exploring the use of Messenger bots in teaching and learning. Practitioner NotesWhat is already known about this topic Mobile instant messaging (MIM) applications (apps) have potential to facilitate effective social constructivist‐based collaborative learning. Students extensively use MIM apps. There is reluctance from instructors to engage in after hours MIM student consultation. Messenger bots can deliver content on demand, using inter alia text, images and video, and the effective use thereof in teaching and learning has not yet been explored. What this paper adds Instructors, without coding knowledge, are enabled to develop Messenger bots for teaching and learning. Social constructivist‐based suggestions for specific teaching and learning applications of Messenger bots are provided. Preliminary evidence suggests students positively experienced the use of Messenger bots in their learning. Implications for practice and/or policy Messenger bots may support instruction in large classes. Messenger bots may be suited to supplemental instruction rather than replacing face‐to‐face instruction. Specific teaching and learning applications of Messenger bots should be implemented and the effectiveness thereof explored.

A modified strain-softening model with multi-post-peak behaviours and its application in circular tunnel

A large number of laboratory experiments have shown that the rocks in post-peak state present strain-softening behaviour under low confining pressure, and gradually evolved into elastic-perfectly plastic with the increasing of confining pressure. Neither the elastic-perfectly plastic model nor the strain-softening model can accurately describe the behaviour of rock mass surrounding the deep buried excavations. In this paper, a modified strain-softening model was proposed to describe the non-linear evolution of residual strength under the influence of confining pressure. The new model can realize the gradually transition from strain-softening behaviour to elastic-perfectly plastic behaviour with the increasing of confining pressure. The equivalent residual strength was defined to quantify the strength of rocks in post-peak stage. The parameters involved in the model were estimated via non-linear regression analysis upon a series of stress-strain curves. Based on the plane strain axial symmetry assumption and the incremental theory of plasticity, equilibrium equations and compatibility equations of rock mass around a circular tunnel were deduced. The equations were implemented in the Visual Basic development environment, and a semi-analytical solution was obtained. The influence of post-failure behaviour of rock mass was demonstrated through an illustrative case. The distributions of stress, displacement and transitional strength around the tunnel were presented. The differences between the elastic-perfectly plastic model, the strain-softening model and the new model were estimated quantitatively. In addition, the validity of semi-analytical solution was verified by numerical simulations. Parameters analysis showed that the tunnel convergence was influenced by the post-peak behaviour of rock mass dramatically.
