High temperature heat exchangers are needed in various energy technologies to increase their efficiency. the article is devoted to the optimization of the design of a high-temperature air heater used in the integrated gasification combined cycle plant, developed in Ural Federal University. In the air heater, air with a pressure of 2 MPa after the cycle compressor is heated by coal combustion to a temperature of 900°C before it is fed into the combustion chamber of a gas turbine. the air heater is developed as a pulverized coal fired boiler with air heating in tubular radiation-convection heating surfaces. the authors propose a new design of a high-temperature air heater, which allows reducing the cost of the expensive high-temperature part of the unit 1.8 times compared with the previous design. A computer simulation of the boiler section is carried out to verify the proposed design solutions. © Published under licence by IOP Publishing Ltd.

the design and scheduling of chemical batch process (DSCBP) is a very well studied problem, due to the wide application in multiple industry sectors, for example, in agrifood, fine chemicals, food specialties, and pharmaceutical. Multi Criteria Decision Making (MCDM) tools are also utilized to address the agri-food supply chains, dealing with uncertainty, coping with computational issues, and developing robust optimization (RO) models. At present, the enlarged version of the problem MS (multiple machines and SPC policy) is shown to be NP-hard in the strong sense: the robust problem RObatch_MS. In this way, heuristics and approximation procedures can be strong options to effectively address these enlarged DSCBP problems, while polynomial algorithms to exactly solve them can be neglected. these computational complexity studies can support innovative approaches and methodologies, improve modeling techniques and solving approaches for agri-food supply chains, while promoting robustness both on models and on solutions. © 2020 EUROSIS.

In this paper we review the overall process for the design, development, and deployment of "What I See Is What You Get", an experiential installation that creates live interactive visuals, by analyzing human facial expressions and behaviors, accompanied by text generated using Machine Learning algorithms trained on the art collection of the J. Paul Getty Museum in Los Angeles. the project is developed by students and faculty in an academic environment and exhibited at the Getty Museum. We also study the pedagogical process implemented to address the curriculum's learning outcomes in an "applied" environment while designing a contemporary new media art piece. Special attention is paid to the level and quality of the interaction between users and the piece, demonstrating how advances in technology and computing such as Deep Learning and Natural Language Processing can contribute to deeper connections and new layers of interactivity.

Based on many years of experience in the development and implementation of systems of continuous monitoring of transport infrastructure facilities, the authors have designed an architecture that allows the most efficient and rational arrangement of such systems. the paper notes the need for and importance of universalizing the development, design and implementation of technical diagnostics and monitoring systems of transport infrastructure facilities. It also gives detailed description of universal monitoring system architecture, as well as a roadmap for the development of universal hardware and software platform for this system. Main components of monitoring systems are de-fined. Recommendations are given to be followed when developing the monitoring systems. It is emphasized that a monitoring system can and should be built to make “energy management” possible through minimization of both energy consumption for implementation of operating procedures and reduction of the carbon footprint from the transport infrastructure facilities. Monitoring systems should be a means that help to build highly immune and energy efficient “green” transport infrastructure facilities.

Wearables, mobile devices and Internet-of-things (IoT) sensors are enabling us to monitor our environment, understand our social connections, and track our personal health. However, most of these systems communicate data through information visualizations that are often 'hidden' inside devices, such as mobile phones and tablets, requiring users to undertake explicit actions to reveal them. Novel interfaces and devices embedded in people's everyday life have the potential to help users visualize, use, and appropriate their collected personal data. To this end, we designed the physical artifact LOOP, which provides an abstract visualization of the user's activity data by changing its shape. In this paper, we elaborate on the design and present a one-week field study in which LOOP was deployed in the homes of five end-users. We found that the physical presence of LOOP facilitated reflection and the layered visualization supported various personal tracking. © 2020 ACM.

computer aided GEOMETRIC design 2021年 86卷

作者： thayyil, Safeer Babu Yadav, Sunil Kumar Polthier, Konrad Muthuganapathy, Ramanathan Indian Inst Technol Madras Dept Engn Design Chennai Tamil Nadu India Free Univ Berlin Dept Comp Sci & Math Berlin Germany

In this paper, we introduce a feature preserving surface reconstruction algorithm to produce a high fidelity triangulated mesh from an input point set. the concept of local Delaunay triangulation is applied to speed up the reconstruction procedure and to preserve features. the proposed algorithm has running time complexity of O(n logn), where n is the number of points. Additionally, the local Delaunay triangulation improves the memory efficiency of the proposed method compared to global Delaunay-based methods. We introduced the concept of minimum circum-radius triangle to select the prime-triangle in the local Delaunay mesh. Based on the local projection and minimum circum-radius, our triangle selection criteria ensures the output mesh will be free from non-manifold edges and fold-over triangles. On top of that, we have provided the theoretical correctness of the proposed algorithm with the assumption of epsilon-sampling model. the experimental results show that the proposed method is capable of producing high fidelity meshes from large real-world non-uniform data. We also show the effectiveness of the proposed method compared to the state-of-the-art methods in terms of visual and quantitative analysis. (c) 2021 Elsevier B.V. All rights reserved.

With the increasing social gap between senior citizens and younger generations, technology can act as a bridge that facilitates interaction. there is a need for an active lifestyle for senior citizens focusing on socialisation, physical activity, cognition, and nutrition. Sahayak, an assistive system for the elderly, explores the use of technology to increase the involvement of the younger generation in their lives. through adopting a user-centered design process, we explore how Sahayak enables older people to be independent and connect with their loved ones, fellow older people, and doctors. It also allows loved ones to gain knowledge of their parents' and grandparents' daily activities regarding their dietary habits, physical wellness, and medical health. Sahayak is an application for a tablet interface with a wristband worn by the user, as a complete system. the aim is to stay updated with the user's medical health status, allowing Sahayak to provide advice regarding nutrition, physical wellness, and emergency alerts. In this paper, we would discuss the user research and design processes along with its importance in our application development. © 2020 ACM.
