Material Layout

Topology optimization (TO) is a mathematical method that optimizes the material layout in a pre-defined design domain. Its theoretical background is widely known for macro-, meso-, and microscale levels of a structure. The macroscale TO is now available in the majority of commercial TO software, while only a few software packages offer a mesoscale TO with the design and optimization of lattice structures. However, they still lack a practical simultaneous macro–mesoscale TO. It is not clear to the designers how they can combine and apply TO at different levels. In this paper, a two-scale TO is conducted using the homogenization theory at both the macro- and mesoscale structural levels. In this way, the benefits of the existence and optimization of mesoscale structures were researched. For this reason, as a case study, a commercial example of the known jet engine bracket from General Electric (GE bracket) was used. Different optimization workflows were implemented in order to develop alternative design concepts of the same mass. The design concepts were compared with respect to their weight, strength, and simulation time for the given load cases. In addition, the lightest design concept among them was identified.

Background: The theoretical background of this article is on the model developed of knowledge transfer between universities and the industry in order to access the best practices and adapt to the study case in question regarding the model of promoting and manage innovation within the universities that best contribute with solution and projects to the business field. Objective: The development of a knowledge transfer model is the main goal of this article, supported in the best practices known and, also, to reflect in the main measurement definitions to evaluate the High Education Institution performance in this area. Methods: The method for this article development is the case study method because it allows the fully understanding of the dynamics present within a single setting, and the subject examined to comprehend what is being done and what the dynamics mean. The case study does not have a data collection method, as it is a research that may rely on multiple sources of evidence and data which should be converged. Results: Since it’s a case study this article present a fully description of the model proposed and implemented for the knowledge transfer process of the institution. Conclusion: Still in a discussion phase, this article presents as conclusions some questions and difficulties that could be pointed out, as well as some good perspectives of performed activity developed.

Passive solar system design is an essential asset in a zero-energy building perspective to reduce heating, cooling, lighting, and ventilation loads. The integration of passive systems in building leads to a reduction of plant operation with considerable environmental benefits. The design can be related to intrinsic and extrinsic factors that influence the final performance in a synergistic way. The aim of this paper is to provide a comprehensive view of the elements that influence passive solar systems by means of an analysis of the theoretical background and the synergistic design of various solutions available. The paper quantifies the potential impact of influencing factors on the final performance and then investigates a case study of an existing public building, analyzing the effects of the integration of different passive systems through energy simulations. General investigation has highlighted that latitude and orientation impact energy saving on average by 3–13 and 6–11 percentage points, respectively. The case study showed that almost 20% of the building energy demand can be saved by means of passive solar systems. A higher contribution is given by mixing direct and indirect solutions, as half of the heating and around 25% of the cooling energy demand can be cut off.

The current historical context is characterised by a significant change in the economic and social fields that have led to the development of the economy of creativity and knowledge. This condition has laid the basis for the rise of a new social class. This radical change in the productive paradigm has started a series of modifications to urban spaces, setting in place a rooted change in the fabric of the city.The objective of this paper is to understand and interpret the nature of the changes under way and to investigate how what occurred in economic and social fields influenced the processes of urban regeneration. Starting from a theoretical background it will examine the concept of creativity applied to economics and social sciences. Secondly, by identifying the urban environment of London as a case study, it will analyze single cases that will show the root of these practices within urban spaces. The purpose of it will be verified by the possibility of building urban transformation strategies that use creativity as the tool of change.

Didactic Issues

2020 márciusában Magyarországon is központilag elrendelték az online oktatásra való átállást a világszerte egyre inkább terjedő SARS-CoV-2 koronavírus terjedése miatt. Ez a digitális átállás szükségszerű változást indukált a magyar oktatási rendszerben. Sok didaktikai kérdés, probléma, akadály merült fel ennek kapcsán, melyre megoldást kellett találni, hogy működjön. Esettanulmányomban ezeket vizsgálom meg, s kísérletet teszek arra, hogy a gyakorlatból hozott példákkal megválaszoljam, s elméleti háttéranyaggal is alátámasszam.In March 2020, the transition to online education was also ordered centrally in Hungary due to the spreading of the SARS-CoV-2 coronavirus. This digital switchover has induced a necessary change in the Hungarian educational system. Many didactic issues, problems, obstacles arose in connection with this, and a functioning solution had to be found for it. In my case study, I examine these and make an attempt to answer them with examples from practice, and I also support them with theoretical background material.

This paper presents the trilogy of virtual classifications, the speculative environment, the virtual inhabitant and the virtual built-form. These combine, generating a new realm of design within immersive architectural space, all to be designed relative to each other, this paper focuses on the speculative environment portion. This challenged computational design and representation through atmospheric filters, visible environment boundaries, materiality and audio experience. The speculative environment was generated manipulating the physical laws of the physical world, applied within the virtual space. The outcome provided a new spatial experience of architectural dynamics enhanced by detailed spatial qualities. Design concepts within this paper suggest at what immersive virtual reality can evolve into. Following an interconnective design methodology framework allowed a high level of complexity and richness to shine through the research case study throughout the process and final dissemination stages.

The Relationship

Purpose – The purpose of this paper is to present an innovative study with a twofold focus: on highly escalated family business (FB) conflicts and on the interactions between conflicts and the failure of the company as FB. The authors devoted this paper to the question of how family-related conflicts are connected with the demise of FB. Conflicts constitute an essential part of every FB and may definitely have the power to superimpose the performance of the FB as well as the family life in a destructive way. Especially, highly escalated so called relationship conflicts can be seen as one reason for the failure of FB. Design/methodology/approach – The research aims at analysing the meaning of conflict in FB with respect to the failure of the FB. Therefore, the authors use an explorative case study approach. The study is based on a total of five case studies. As the authors use theory of social systems as a theoretical background, the authors focused in the analysis in all cases on patterns rather than on individual characteristics. Findings – As an essential part of the study the authors formulated eight hypotheses describing specific patterns of the conflict process as a communicative system. These hypotheses convey a comprehensible impression of the effects conflicts may have within FB and present a number of new facets of conflict dynamics and patterns of escalation in FB. Originality/value – In particular, the authors provide new insights into the dynamics of highly destructive forms of conflicts in FB and the relationship between family-related conflicts and the failure of FB. The authors also pave the way for future research that aim to develop a more holistic understanding about when and why the outcomes from family and business systems will conflict or be harmonious.
