Related Work and Motivation for Electric Vehicle Solar/Wind Charging Stations: A Review
No full textThe shift towards sustainable transportation is an urgent worldwide issue, leading to the investigation of creative methods to decrease the environmental effects of traditional vehicles. Electric vehicles (EVs) are a promising alternative, but the issue lies in establishing efficient and environmentally friendly charging infrastructure. This review explores the existing research on the subject of photovoltaic-powered electric vehicle charging stations (EVCSs). Our analysis highlights the potential for economic growth and the creation of robust and decentralized energy systems by increasing the number of EVCSs. This review summarizes the current knowledge in this field and highlights the key factors driving efforts to expand the use of PV-powered EVCSs. The findings indicate that MATLAB was predominantly used for theoretical studies, with projects focusing on shading parking lots. The energy usage varied from 0.139 to 0.295 kWh/km, while the cost of energy ranged from USD 0.0032 to 0.5645 per kWh for an on-grid system. The payback period (PBP) values are suitable for this application. The average PBP was demonstrated to range from 1 to 15 years. The findings from this assessment can guide policymakers, researchers, and industry stakeholders in shaping future advancements toward a cleaner and more sustainable transportation system
Personalized Learning in Automation: A 3D AI-Based Approach
No full textIn today's technology-driven world, the need for interdisciplinary skills is increasing. This has become challenging in tertiary education to provide students with applicable knowledge of various fields. Anderson's Adaptive Control of Thought (ACT) theory suggests that universities have traditionally focused on imparting declarative knowledge, which involves memorization of facts and concepts. However, imparting the ability to apply such knowledge on individual students and create procedural knowledge is the challenge. This includes teachers dealing with a diverse range of student abilities, particularly at university-level where they teach the same course content to students with different levels of prior knowledge and, given the structure of modern education systems, the resources required to monitor and provide feedback for a number of decisions and attempts independently performed by the students. Intelligent Tutoring Systems (ITS) have proven to be effective in addressing the aforementioned challenges by creating personalized learning environments that provide instant feedback, adapt to individual student needs, and promote the development of procedural knowledge. In the field of automation education at the university level, we are creating a 3D artificial intelligence (AI)-based ITS software named KIAAA (An AI Assistant for teaching in the field of automation), specifically designed to teach computer programming to students. KIAAA aims to assist students in transitioning from their abilities to procedural aptitude by providing personalized learning scenarios that allow them to apply their knowledge and receive immediate feedback. Our approach is based mainly on the pedagogical model of ITS, which focuses on creating a supportive and inclusive learning environment that promotes success for all students, regardless of their initial level of knowledge. One of the key aspects of our approach is the utilization of personalized learning. We propose a scheme that, subsequent to evaluate student's initial levels of procedural knowledge, creates 3D learning environments tailored to each individual student. By analyzing the solutions proposed by the students, we select the difficulty level of subsequent tasks. This approach takes into consideration student's discrete competence throughout the learning process, enabling them to progress on their prior knowledge. Additionally, the software provides customized feedback to each student on their performance, helping students identify areas that require improvement. Concepts for and implementations of ITS for a variety of fields, including introductory programming classes, have evolved for a long time. Our main contribution lies in presenting an end to end solution for ITS focused on teaching programming for automation students with realistically 3D simulated factory environments. While we strongly believe to have created a pedagogically sound, integrated intelligent teaching system for assisting programming classes in tertiary automation education, a robust user study for methodically evaluating our concept and implementation is still to be performed. Thus, we limit ourselves to presenting the underlying didactic concepts of KIAAA as a work in progress paper with a comprehensive evaluation to follow at a later date
The Use of Situated Visualized Data to Nudge Visitor’s Paths: a Case Study at the Detmold Design Week 2023
No full textIn light of the rising importance of data transparency and open data guidelines (e.g. OGP Local1), Open Data Portals became standard in Smart City strategies (Van Oosterhout et al. 2020). While it is clear that these tools can serve as a valuable way for internal administration processes, at the same time it is critical that data is not only openly available following standard formats limited to computer-readability but above all also largely understandable for average citizens. For this reason, it is researched how open data can not only be made available but also visualized in an accessible way to all citizens. Moreover, the aim is to simultaneously boost private behavior changes which are inevitable to achieve locally-set goals in sustainability (Barr et al. 2011, TWI 2050 2018). To do so, we draw on the principle of nudging. Following
the tradition of behavioral economics, nudging is defined as a positive intervention that induces a voluntary change in behavior without resulting in external (negative) consequences (Thaler & Sunstein 2008) and thus contrasting interventions like commands or bans because freedom of choice is maintained (Mongin & Cozic 2020, Ranchordás 2020).
This paper discusses an installation that explored the potential of combining nudging and situated visualization to improve data transparency and support individual decision-making in urban public spaces. During the Detmold Design Week 2023, an event showcasing creative works in various locations, the visitor numbers at nine locations were captured using computer vision. Visitors then received on-site suggestions in real-time for the next place to visit based on the occupancy. A survey was conducted to evaluate visitors’ willingness to follow these data-informed suggestions. Findings highlight the importance of balancing between simplicity, relevance and privacy in data visualization. The results of the field test provide the foundation for the installation of interactive interfaces in Detmold's public spaces in the next years, in particular for communicating smart city topics focusing on mobility and urban climate protection

No full textR-Strategien als Instrument für zirkuläres Bauen
No full textDie Transformation zum zirkulären Bauen ist elementar, um ressourcenschonend, langlebig und klimagerecht zu bauen. Es wird ein Vokabular benötigt, um diesen Wandel zu benennen und in die Praxis umzusetzen (Seggewies et al., 2018). Als etabliertes Framework bilden die R-Strategien (z.B. Reduce, Reuse, Recycle) ein wirksames Instrument, um die Abfallhierarchie und die Übergänge zwischen den Lebenszyklen zu beschreiben (Kirchherr et al., 2018). Dabei sind sie für die Entwicklung zirkulärer Produkte, Prozesse und Geschäftsmodelle hilfreich (Prosperkolleg.ruhr, 2022). Eine Meta-Studie zeigt, dass knapp ein Drittel aller untersuchten Publikationen auf die R-Strategien verweisen, sich lediglich 13% auf baupraktische Lösungsansätze oder die Kombination dieser mit der Ökobilanzierung beziehen (Ossio, 2023).
Aktuell existiert somit kein spezifisches Vokabular, dass die R-Strategien anwendbar und verständlich im Kontext des zirkulären Bauens definiert. Im Rahmen des Verbundprojekts „CirQuality OWL plus“, werden Instrumente zur Umsetzung der Circular Economy regional entwickelt und implementiert, um aktiv Klimaschutz zu betreiben. Die vorliegende Veröffentlichung erweitert die R-Strategien für die verschiedenen Ebenen von Gebäuden ‒ Material / Ressource, Bauteil / Produkt und Gebäude ‒ sowie die differenzierte Betrachtung von Bestandsgebäuden und Neubauten. Anwendungsmöglichkeiten und -grenzen werden definiert und für den Übertrag in die Praxis dargestellt. Die spezifische Definition der R-Strategien für das zirkuläre Bauen ermöglicht eine klare Benennung zirkulärer Lösungen für verschiedene Akteure des Bausektors. Wissensmanagement und Kommunikationsfähigkeit bilden somit den Ausgangspunkt für die Bauwende

Get PDFApproximate calculation of changes in local and global quantities due to design modifications.
No full textThis contribution introduces a method for goal-oriented and global reanalysis. It allows the prediction of changes in selected quantities of interest by using the changes in the primal and dual so lutions resulting from structural modifications (e.g., changes in shape, topology, or material properties). Theapproach uses a goal-oriented method that includes both primal and dual problems. In particular, this method is easy to integrate into existing finite element programs because it does not require derivatives with respect to design variable
Modernism in Africa The Architecture of Angola, Ghana, Mozambique, Nigeria, Rwanda, South Africa, Sudan, Tanzania, Uganda
No full textMany African countries are home to extraordinary architecture that is virtually unknown. There are interpretations of Art Deco, International Style, Brutalism as well as of African vernacular architecture. Climate-responsive buildings with a fluidity of interior and exterior spaces play a large role. While many of these 20th century architects were of European origin, they were deeply influenced by their surroundings and found original, site-specific expressions, often in collaboration with African architects. A focus of the construction activities were educational buildings which played an important role for these young nations that mostly gained their independence in the 1960s. While some of the documented buildings have been restored, others are still awaiting reconstruction
Four Stages of Co-Creation
No full textCo-creation is a process of jointly developing solutions, products, or services by engaging a variety of stakeholders. This approach leverages the collective knowledge, insights, and creativity of a diverse group to create more effective outcomes than what might be achieved through traditional, top-down approaches. In the context of urban regeneration, this involves bringing people together to conceive, discuss, plan, design, and implement solutions that possess a substantial added value. URBiNAT’s goal of establishing ‘Healthy Corridors’ and implementing Nature-Based Solutions (NBS) that promote social cohesion is based on an inclusive and democratic co-creation process as a means to unite the community in addressing shared needs and aspirations. Towards this end, we have designed a co-creation model based on a four-stage approach: Co-diagnostic (local diagnosis), characterizing the area of intervention in territorial, social and economic terms; Co-design (the project), involving citizens in the process of building ideas and strategies, and in the design of solutions; Co-implementation (construction), inviting citizens to participate in the production of solutions, through volunteer work or exchange of working hours; Co-monitoring (evaluation), challenging citizens to convey the benefits and potential drawbacks of the implemented solutions. The roadmap for the co-creation of nature-based solutions is based on the co-creation model, which was applied in the eight cities of the project
