The article presents the main aspects of the implementation, use and pilot and industrial experiments of some self-contained recovery burners. The results of pilot and industrial experiments of these burners have argued and quantified their energy efficiency. This efficiency consists mainly in an economy of specific fuel consumption (natural gas and / or coke gas) of approx. 25-35%. Other advantages of using recuperative burners are: ensuring a higher temperature in the hearth, reducing the duration of the processing cycle and thus increasing labor productivity. All these advantages of using recuperative burners are based on their operating principle, which consists in preheating the oxidizer (combustion air) by recovering an important part of the enthalpy of its own flue gases. This recovery is done in an energy recuperator designed right in the body of the recuperative burner. Due to this important aspect, the recovery burner is part of the Primary Energy Recovery (REP) category.

This article presents the main aspects of the conception, design and construction of selfdesigned recuperative burners. The starting point of the article is the operating principle of this specific type of combustion plant. This operating principle is based on the preheating of the combustor (combustion air) by taking over an important part of the enthalpy of its own combustion gases. Based on this principle, the recuperative burner of our own design has an energy efficiency that consists in reducing the specific consumption of fuel (natural gas) by about 25-35%. Also, the use of this specific type of combustion plant provides other functional advantages such as: a higher temperature in the hearth (due to a complete combustion), reduction of technological cycle times for the realization of various processes. The article also presents some functional parameters of a type-dimensional range of recuperative burners of our own design.

The logo is a graphic element that can take the form of a letter, text, image, or even combinations of all these elements. It is used to identify a brand, product, organization or event. Any business, regardless of its size, must have a logo to define it. Nowadays, communication has become dominated by its visual composition. The world in which the rhythm is increasingly accelerated, communication strategies must emphasize what is possible to transmit instantly, with minimal effort, to the person who is looking. Starting from this premise, in this paper, we will present why it is good to create your own logo and what are the aspects to be taken into account when doing so. Well, our goal is to find a logo that has positive connotations for the business we want to promote. In this paper, a list of quality logo services and tips has been created to help people while creating an original logo for a business. Finally, we have written an idea on how to start creating a logo for a business that provides credibility in interacting with potential customers. We need a professional logo, colorful, versatile, that has positive visual impact, but at the same time it is affordable, and can be purchased by any small creative workshop.

• A methodology for fan efficiency deployment was proposed. • The axial flow maldistribution drops the overall fan efficiency by 14%. • A sensitivity analysis of seven fan parameters was carried out. • Comparisons against the predictions of the fan laws were conducted. • The pitch angle is the most influencing parameter on the fan performance. This paper advances a methodology for axial fan efficiency mapping followed by a design optimization exercise of a low-pressure axial fan for small capacity refrigeration applications. For these purposes, a tailor-made first-principles simulation model based on the so-called blade element theory (BET) was put forward. First, the fan efficiency was deployed into two terms – namely, electric motor and blade efficiency, which in turn was split into two other terms that account not only for the irreversible losses but also for flow maldistribution – in order to identify opportunities for blade optimization. Later, a sensitivity analysis was performed to find out the optimum values of key operating and design parameters of the fan, namely motor speed, blade size and number, chord length, pitch angle, and airfoil characteristics, such as thickness and maximum camber values. Among those, the pitch angle stood out as the most influencing parameter affecting the fan characteristics, including the airflow rate, the power consumption, and the blade efficiency. Comparisons with results obtained by means of the so-called fan laws are also reported for the blade size and speed. [ABSTRACT FROM AUTHOR]

As fully prefabricated wood walls (FPWW) are envisioned to increase building envelope performance, the junction between panels becomes crucial. Since FPWW restricts access to the inter-panel joints, it is preferable to generate an upstream mechanism to complete the joint automatically on-site. This study aimed to design a self-sealing joint for FPWW that would achieve high energy standards and accelerate on-site construction. Airtightness tests and thermal bridge assessments were conducted in the laboratory to compare the developed self-sealing joints with different sealing materials. These same tests were conducted on-site, in addition to observations of the assembly speed of conventional prefabricated walls and FPWW. Of all the materials tested, butyl tape showed the tightest connections. This material helps the joint developed to automatically seal adjacent walls spaced up to 7 mm apart. FPWW maximize the industrialization of conventional prefabricated walls by realizing the sealing details and the installation of doors, windows and exterior siding offsite. This way, FPWW could reduce the duration of a conventional single-family residential project. FPWW maximize quality control while reducing transportation costs associated with conventional modular solutions. [ABSTRACT FROM AUTHOR]

Fishing is a risky activity that has been mainly studied in ergonomics in order to optimize safety on board. The current ecological situation has led us to take an interest in a new way of fishing in order, among other things, to design more environmentally friendly fishing gear. Until now, no study has focused on how fishermen use fishing gear. Based on in situ observations on board two fishing boats and on explicitating self-confrontation interviews with four sailors, this study describes the use of fishing nets at different levels of the fishing activity: macro, meso and micro. It highlights the mechanical stress suffered by fishing nets and the patterns of use mobilized by the deckhands during the unmeshing of the catch. The results help to enrich the specifications for the design of biodegradable fishing gear, to enlighten the design teams on real fishing activity, and to build an environment facilitating the transition from current fishing practices to more sustainable ones.

• The design method was simple and effective. • Experimental and simulated performances matched well. • Purity of 99.9% was obtained experimentally after 22 h. • Save 36.5% and 43.7% in terms of operating cost and TAE, respectively. • The use of an advanced distillation configuration in industrial applications is viable. In this study, the reclamation of Halon 1301 from an industrial waste gas mixture using an existing heat-pump-assisted batch distillation system was investigated. A cold water circuit and a hot water circuit are added to the conventional vapor compression heat pump for easy operation. To design and optimize the separation, where several design variables and constraints must be verified and satisfied, a modification of the design methodology proposed by Long et al. (2020) was used. Following design using Aspen Hysys software in the simulation of the shortcut column and heat pump system and Aspen Batch Modeler in the simulation of batch distillation, experimental operation of the existing heat-pump-assisted batch distillation system was performed to purify Halon 1301. The experimental performance matched well with that in the simulation. The purification of Halon 1301 with purity of 99.9% was accomplished after 22 h under the designed and optimized operating conditions. The results show that the reboiler duty and operating costs of the existing industrial system can be saved by as much as 100.0% and 36.5%, respectively, compared with a conventional batch distillation column. In addition, the total CO 2 emission was reduced by as much as 43.7% compared with that of the conventional process. Moreover, the proposed design is convenient and gives reliable performance. This study demonstrated that the use of an advanced distillation configuration in industrial applications is practically viable and economical. [ABSTRACT FROM AUTHOR]

In what way are chatbots new resources for humans? What are the conditions for their successful implementation? How do chatbots transform human activity? To answer these questions, this paper investigates how four chatbots were implemented and utilized in a professional context based on real user activity. We first show that the current design approach does not take sufficient account of the real activity and its multiple determinants, or of the users' point of view on their activity. Yet these interactive devices participate in a pre-existing socio-technical system made up of a diversity of subjects engaged in activities with multiple purposes. Through the prism of instrumental geneses, we therefore propose to identify how these chatbots can help or hinder human activity, so as to document, for design purposes, the conditions leading to the emergence of chatbot uses. After a synthetic presentation of the empirical results, we discuss the relevance of the instrumental approach when characterizing the contributions and limitations of chatbots. Finally, we argue that a design perspective supporting the postulate of human-machine asymmetry is prolific in supporting a design approach that is more focused on human power to act than on innovation.

The article presents the process of designing the details of shoe upper for schoolchildren using the numerical characteristics of the feet and modern computer technology. A software module for processing the obtained data in the MathCad Education program has been developed, which allows to create parametric models of the foot and longitudinal-vertical section of the internal shape with a deviation of not more than 5%. It is established that developing parametric aspects of shoe upper design is advantageous in the age range from 11 to 13 years. Patterns between different parameters of schoolchildren’s feet are also determined. On the basis of the developed parametric models and the proposed principles of modular transformation the construction of low shoes (half-boots) is designed and made. [ABSTRACT FROM AUTHOR]

In addressing geography's neglect of shade and shadow, this paper explores how the dynamic play of shadow and light constitutes an integral part of everyday affective and sensory attunement to place and guides pedestrian movement. First, we identify how particular shadows are shaped by distinctive kinds of solar radiance, material forms, human visual perception and cultural representations. We then consider the different cultural ways in which shade and shadow have been interpreted across space and time and identify diverse shadowy effects in different geographical contexts. Thereafter, we focus on particular key elements of central Melbourne's shadow aesthetics, discuss how patterns of shade guide urban choreographies, and explore how architects have imaginatively manipulated shadow.

Due to the constraints it has placed on businesses and society, the health crisis that broke out in 2020 has generated various forms of distancing from the workplace (confinement, teleworking, space occupancy gauges, etc.). In many sectors the continuity of economic activity has been achieved through the massive use of digital technologies, particularly videoconferencing. These new methods have reconfigured the work communities that traditionally practice face-to-face. It is therefore the territories of work, i.e. the ecosystems of relations that structure common productive action, which have been profoundly restructured. Ergonomists have not escaped these upheavals. Their territories of intervention have been shaken up to the same extent that the work territories of the beneficiaries of their services have been transformed. This article aims to report how new territories of intervention in ergonomics have been explored through the application of a professional gesture - the simulation of work - in a context where it could not be performed face-to-face. After clarifying the concepts of territory of intervention and recalling the methodological requirements of work simulation, we describe three interventions initiated in 2020 in the context of the pandemic. They reflect the birth and consolidation of remote simulation of work. Despite the distance, these interventions made it possible to examine three privileged areas of ergonomics: prevention advice, the design of work situations and training. [ABSTRACT FROM AUTHOR]

This paper draws upon Actor Network Theory (ANT) to explore material and social dynamics of a coastal community garden site on public housing grounds in Rockaway, NY after Hurricane Sandy. Through a participatory design-research project, we examine shifting associations between humans and non-humans as a way of interrogating agency, power dynamics, and governance. Acknowledging our own outsider status, we draw upon the frame of 'contact zones' for thinking through encounters in conditions of power differentials. In describing our encounter with the Beach 41st Street Community Garden as a contact zone, we identify three assemblages with different governance arrangements – tidal shore, garden plots, and treed lawn. These assemblages are networked through material flows and include nonhuman actants such as freshwater, soil, plants, and wood. Unruly actors and actants – people, saltwater, poison ivy, dogs, and trash – can spark controversy and resist governing. We reflect upon the role of design, research, and community organizing as interventions that can cause rearrangements of the assemblages, shedding new light on power dynamics and potential apertures for change in a dynamic site. In so doing, we mobilize contact zones and ANT to better understand and act within shifting associations between humans and non-humans. [ABSTRACT FROM AUTHOR]

There is a growing interest in urban form as the spatial concretization of urban sustainability. At the core of sustainable urban form is the spatial pattern of the different types of the physical objects characterizing the built-up areas of settlements at different spatial scales. The spatial features of urban design is key to producing the benefits of sustainability and enacting its effects as outcomes of processes. However, it has been difficult to evaluate how and to what extent sustainable urban forms contribute to sustainability and to judge whether or not a certain sustainable urban form is actually sustainable. Therefore, there is a need to find more effective ways to address and implement the spatial scaling of sustainable urban form in an attempt to increase the positive outcomes of sustainability. This relates to the emerging model of sustainable cities, which is increasingly being enabled by urban computing and intelligence in terms of planning and design under what has been termed "data-driven smart sustainable cities". This paper analyzes and discusses the emerging conceptions of and approaches to spatial scales that should be considered in the planning and design of data-driven smart sustainable cities of the future. In doing so, it highlights the innovative potential of urban computing and intelligence for enhancing and transforming the spatial scaling of sustainable urban form. I argue that data-driven technologies allow sustainable urban forms to monitor, understand, and analyze the different aspects of their spatial scaling for generating the kind of designs that improve sustainability. Conceiving spatial scales as outcomes of processes and planning accordingly hold great potential for attaining the goals of sustainability. Sustainability outcomes are multi-scalar in nature, which justifies the need to integrate spatial scales that have clear synergies in their management and planning and need to be coupled. This synergic integration produces combined effects that are greater than the sum of the separate effects of spatial scales with respect to sustainability benefits. [ABSTRACT FROM AUTHOR]

SMACH (Multi-Agent Simulation of Human Activity and Consumption in the Home) is a simulation platform that is part of EDF's research and development framework. It aims to use simulation to anticipate and reduce energy consumption at different levels of analysis (housing, neighborhood, city, country). The aim of this article is to characterize a "course-of-action" technological research program by referring to several years of SMACH research work. We mainly focus on the importance of the organic relationship between technology and human activity and we show the evolution of this organic relationship as we follow the different stages that characterize this technological research program. This article can be seen as a basis for generalizing and specifying the effective criteria for validating a technological research program and as a contribution to a reflection on design in ergonomics.

SMACH (Multi-agent Simulation of Human Activity and Household Consumption) is a simulation platform within EDF's R&D framework. It uses simulation to anticipate and reduce energy consumption at different places of analysis (home, district, town, country). With this paper we aim to explain what the course of action technological research program involves, and to this end we refer to several years of SMACH research. We essentially focus on the importance of the organic relationship between technology and human activity, and we show how this organic relationship evolves over the different stages that this technological research program involves. This paper may be viewed as a basis for generalizing and clarifying the criteria required to validate such a program and as a contribution towards reflection on design in ergonomics.

The project's temporality facing the ethical dilemmas of citizen participation - Urban development projects mobilize a complex network of stakeholders (PP) that intervene at several scales and decision-making levels of the project. These PPs represent different and sometimes divergent interests. Research on development actors has shown the emergence of new paradigms that have a significant influence on decision-making processes. Among these, citizen participation (CP), presented as a modality that aims for "direct democracy" and "social justice", and to promote the social acceptability of projects. Paradoxically, CP sometimes becomes a source of conflict and controversy, leading to complexification or even slowing of project processes. The purpose of this article is to understand the influence of CP-related conflicts and controversies on project timelines. We will approach this phenomenon from the angle of ethics, understood as the driving force of social justice. Based on the analysis of a construction project for a primary school in a borough of the city of Montreal, the observation of the phenomenon under the lens of ethical theories allows us to highlight the main controversies stemming from the CP and their effects on the time of project completion. The analysis shows that the participatory approach, which was initially put in place from the perspective of social inclusion and experimentation of new project cultures, led to a long decision-making process.

This contribution discusses the degrees of freedom that could be advantageously exploited in the conception of permanent magnet (PM) machines in the context of very demanding applications, such as electrical vehicle traction. The aim is to inventory degrees of freedom identified in scientific and technical literatures. Identifying these additional degrees of freedom will help positively respond to highly constrained design problems, which are appearing due to the higher usage of electrical energy in many industrial and consumer products. The goal is also to stimulate new ideas in the design of PM synchronous machines.
