Abstract

Purpose

The purpose of this paper is to investigate the process of fused filament fabrication (FFF) of a compliant gripper (CG) using thermoplastic polyurethane (TPU) material. The paper studies the applicability of different CG designs and the efficiency of some design parameters.

Design/methodology/approach

After reviewing a number of different papers, two designs were selected for a number of exploratory experiments. Using design of experiments (DOE) techniques to identify important design parameters. Finally, the efficiency of the parts was investigated.

Findings

The research finds that a simpler design sacrifices some effectiveness in exchange for a remarkable decrease in production cost. Decreasing infill percentage of previous designs and 3D printing them, out of TPU, experimenting with different parameters yields functional products. Moreover, the paper identified some key parameters for further optimization attempts of such prototypes.

Research limitations/implications

The cost of conducting FFF experiments for TPU increases dramatically with product size, number of parameters studied and the number of experiments. Therefore, all three of these factors had to be kept at a minimum. Further confirmatory experiments encouraged.

Originality/value

This paper addresses an identified need to investigate applications of FFF and TPU in manufacturing functional efficient flexible mechanisms, grippers specifically. While most research focused on designing for increased performance, some research lacks discussion on design philosophy, as well as manufacturing issues. As the needs for flexible grippers vary from high-performance grippers to lower performance grippers created for specific functions/conditions, some effectiveness can be sacrificed to reduce cost, reduce complexity and improve applicability in different robotic assemblies and environments.

Abstract

In this chapter, I will first conceptualize social movement theory before examining the importance of student movements and student activism. I then will link social movement theory to the university in Egypt. Next, I will contextualize university activism by describing the authoritarian structures of Egypt’s university system. Then, using secondary data sources, I will characterize university activism during the three transitional political periods (under the Supreme Council of the Armed Forces (SACF), under President Morsi, and after the ousting of Morsi), and conclude with a discussion on the implications of student activism on future university reform.

Abstract

Purpose

The impact of the coronavirus disease 2019 (COVID-19) pandemic on architectural education (AE) was investigated, and a framework was proposed to reduce the impacts' negative consequences.

Design/methodology/approach

Systematic literature review, bibliometric and content analyses were combined to gain an in-depth understanding of the effects of the pandemic on AE and projections for its future. Relevant documents were extracted from the Web of Science (WoS) database. Bibliometric connections in the context of AE and COVID-19 pandemic were explored using text-mining and content analysis was performed.

Findings

The challenges, development tendencies and collaboration networks in AE during the pandemic were quantitatively and qualitatively analyzed. The most influential articles, journals, authors and countries/regions were highlighted using a bibliometric analysis. The analysis of keyword tendencies and clusters indicates that new concepts have emerged in AE research during the pandemic involving online, in-person and hybrid education. Using content analysis of 57 subtopics, 39 (18) were categorized as having negative (positive) effects. A comprehensive mitigation framework was designed to reduce the impact of the pandemic on AE.

Research limitations/implications

The study findings can enable practitioners to construct effective solutions to COVID-19- and other disaster-related problems regarding AE. The implications, obstacles and mitigation framework presented can help identify gaps in the literature and guide further research.

Originality/value

This paper presents the first bibliometric and content analysis of AE and COVID-19 pandemic-related studies published from January 2020 to June 2022 to highlight several research directions and academic development within the field.

Abstract

Purpose

Despite the dramatic increase in construction toward additive manufacturing, several challenges are faced using natural materials such as Earth and salt compared to the most market-useable materials in 3D printing as concrete which consumes high carbon emission.

Design/methodology/approach

Characterization and mechanical tests were conducted on 19 samples for three natural binders in dry and wet tests to mimic the additive manufacturing process in order to reach an efficient extrudable and printable mixture that fits the 3D printer.

Findings

Upon testing compressive strength against grain size, compaction, cohesion, shape, heat and water content, X-Salt was shown to record high compressive strength of 9.5 MPa. This is equivalent to old Karshif and fire bricks and surpasses both rammed Earth and new Karshif. Material flow analysis for X-Salt assessing energy usage showed that only 10% recycled waste was produced by the end of the life cycle compared to salt.

Research limitations/implications

Findings are expected to upscale the use of 3D salt printing in on-site and off-site architectural applications.

Practical implications

Findings contribute to attempts to resolve challenges related to vernacular architecture using 3D salt printing with sufficient stability.

Social implications

Benefits include recyclability and minimum environmental impact. Social aspects related to technology integration remain however for further research.

Originality/value

This paper expands the use of Karshif, a salt-based traditional building material in Egypt's desert by using X-Salt, a salt-base and natural adhesive, and investigating its printability by testing its mechanical properties to reach a cleaner and low-cost sustainable 3D printed mixture.

Abstract

Purpose

The present work reviews the impacts of the Covid-19 pandemic on architecture education (AE), with the aim of discussing the interaction and integration of technology-based models.

Design/methodology/approach

Different research methods were used to achieve the research purposes including an online survey, semistructured interviews, observations and reviewing recent literature. The study proposes a theoretical framework to investigate blended learning (BL) approaches in AE, based on the blended teaching–learning continuum, the growth of online delivery mode and technology integration and the gradual responsibility adopted for the current Covid-19 pandemic.

Findings

The study proposes a vision to reimagine post-Covid-19 education and the required BL strategy to provide a theoretical framework that integrates the instructional models required to be investigated by instructors.

Research limitations/implications

The research findings are based on a theoretical approach not tested practically. A further detailed investigation is required. Thus, the road to reimagining the post-Covid-19 AE is still evolving.

Social implications

As faculty members, one should take steps toward preparing BL strategies. These strategies present other alternatives to continue teaching and learning while keeping safe in any other emergency in education. In this work, an overview of BL approaches, continuum and related technological and instructional models has been shaped to propose a new vision to post-Covid-19 AE.

Originality/value

This paper responds directly to the initiated call on the pandemic's effect on traditional education by taking a pedagogical perspective. The study presents a holistic BL strategy and proposes a new theoretical and instructional model to design a suitable and balanced BL environment in AE.

Abstract

Purpose

The promotion of sustainable design is demanded globally. The life cycle assessment (LCA) proved its reliability in this mission, but the difficulty and time required to apply it discouraged designers. This research aims to integrate LCA into the building design process through a software tool, taking advantage of generative design features. This will facilitate decision-making by architects and construction professionals.

Design/methodology/approach

The study develops the EGY-LCA (http://egy-lca.com/). This prototype tool suggests exterior wall design alternatives for residential buildings in Egypt, using the environmental impact indicators of LCA data and other criteria related to national codes, materials, construction methods and required thermal resistance. Within a generative design process, the algorithm tests every possible wall method with materials and thickness combinations for each layer in compliance with inputs. The paper begins by explaining the tool’s working method. Afterward, different sets of inputs are examined and the values of the resultant environmental impacts of several suggested wall solutions are statistically analyzed. The application demonstrates the importance of the generative design tool. Proposing several solutions based on a set of inputs facilitates the selection of sustainable choices and allows comparisons between alternatives.

Findings

The prototype experiment confirms the research hypothesis. Unlike the available LCA tools, architects can make decisions with limited LCA experience if the data and equations are integrated into a generative design tool. The prototype proves its applicability for exterior wall alternatives.

Research limitations/implications

The prototype is the initial step toward a whole-building LCA tool. It includes limited LCA stages and materials for the external wall. Future research is required to expand this parametric tool concept to include all the building components. The framework in Section 5 proposes a visualization.

Practical implications

The prototype tool: EGY-LCA (http://egy-lca.com/). The value added to the design and construction sectors through the uncomplicated LCA application is fostering sustainable design, generative design tools can achieve this.

Originality/value

The novelty of this work is that it is the first initiative offering a parametric LCA tool. It promotes the application of LCA at the design stage using generative design, which contributes to sustainable development.

Abstract

Purpose

Online learning has many limitations in studio-based courses, such as architectural design courses, considering the challenges during post-pandemic. Therefore, this study aims to propose a post-pandemic adopted learning approach, which integrates flipped classrooms (FC) with project-based learning (PBL). In addition, this study evaluates the perceptions of students based on and the effects of the proposed learning approach in architectural design.

Design/methodology/approach

This study provides a mixed methodology based on a literature review on the topic to bridge the gaps in previous studies regarding the FC and PBL. In addition, a case study survey including semi-structured interviews, observations questionnaire recruited undergraduate students to generate both qualitative and quantitative data to investigate the perceptions of students based on post-pandemic adopted learning approach.

Findings

This study has highlighted the significance of post-pandemic adopted hybrid learning method, especially in architectural education, whereas the research finds that FC is an appropriate solution to improve design courses with online technologies.

Practical implications

The proposed approach provides specialists to develop and integrate proposals and strategies to enable a better online practice for students and instructors. The proposed approach can enhance the students' interpersonal skills, hence active online learning related architectural design projects.

Originality/value

Recognizing the significance of e-learning in response to the post-pandemic scenario, this study developed and assessed new learning technique that combines online learning with traditional design studios via hybrid learning method.

Abstract

Purpose

Since the teaching of architecture is now carried out in architectural studios with the critique session as the core of its assessment, the aim of this paper is to analyse architecture students’ attitudes, satisfaction levels and experiences in terms of different critique and assessment methodologies.

Design/methodology/approach

The study relies on two main approaches – the literature and questionnaire survey. In addition, the study relies on the author’s personal observations in design studio teaching and as a practitioner of the method.

Findings

It is important to establish clear goals for design critique and assessment and to include different critique methodologies – self critique, peer critique, group critique and professional critique. All such methodologies should be undertaken in an interactive environment that facilitates communication and exchange of scholarly thoughts among students, instructors and other professionals.

Practical implications

The study involves the investigation of students’ responses and reactions to the various critique methodologies and their underlying practices in the context of Egypt. This is based on the questionnaire survey undertaken by the author in 2016. The questionnaire is designed to generate both qualitative and quantitative data.

Social implications

This study aims to understand the students’ perspective about their design experiences with regard to studio-based learning and its impact on their education.

Originality/value

While the topic of design critique about students has been studied heavily in the Western world, there is a lack of similar information in most Egyptian universities. To fill this gap, the Architecture Program at Port Said University was closely observed.

Abstract

Purpose

Passive design strategies contribute to improving indoor comfort conditions and reducing buildings' energy consumption. For several years, courtyards have received wide attention from researchers because of their significant role in reducing energy demand. However, the abundance of multi-story buildings and the courtyards' incompatibility with them, the courtyard is currently limited. Therefore, it is necessary to search for alternatives. This paper aims to bridge the gaps in previous limited studies considering skycourt as a passive alternative on the vertical plane of the facades in contrast to the courtyard.

Design/methodology/approach

This research presents an overview and a bibliometric analysis of the evolution of the courtyard to the skycourt via VOSviewer software and the bibliometrix R package.

Findings

The research provided various concepts related to skycourt as a promising passive design strategy, which can be suitable for multi-story buildings, starting with its evolution, characteristics, configurations, benefits, and challenges.

Practical implications

The findings can urge designers, researchers and policymakers to incorporate such an important passive alternative.

Social implications

Researchers, instructors, educational specialists, faculty members, and decision-makers can provide design motivation for skycourt in buildings, in addition to achieving awareness about skycourt and its significant benefits and its role as an important passive design strategy.

Originality/value

The research highlights the possibilities of the skycourt and its role as a passive design element as an extension of the courtyard in addition to identifying design indicators that help designers determine the appropriate designs.

Abstract

This chapter takes a look at the evolution of Egypt’s educational system under different regimes that were in power during the years of 1954–2011. By analyzing the education policy under the regimes of Gamal Abdel Nasser, Anwar El Sadat, and Hosni Mubarak, the chapter aims to show how different ideologies have influenced the educational system and the larger goals of social development in the country. In particular, the chapter will highlight the “open door policy” of economic liberalization and the abolishment of the guaranteed government employment policy for graduates that was initiated by Anwar El Sadat and continued during the Mubarak’ era. This became one of the factors that led to growing resentment against state’s policy and fueled the revolution in 2011. The chapter will conclude that the historical context provides a lens to understand the complexity of how education systems are formed and reformed under various regimes and ideologies, and the ensuing consequences of social inequity. What remains to be seen is how educational policy will be shaped in post-revolution Egypt.
