A talha da igreja de Jesus de Aveiro 1
No full textCommented reading to the space of the church of Jesus as a heavenly metaphor and its
impact on the believer, in particular the Aveirenses who frequented it. In this context, it is intended to understand the aesthetic, formal and morphological evolution of the carving and gilded work of the Church of Jesus as a space integrated in the National Baroque [Churches lined with gold]. Starting from the concept of "Church Lined with Gold" we will pay homage to a researcher and author of the unique work "The Talha in Portugal", published in 1962 (54 years ago), Professor Robert Smith, which goes on to quote: Baroque tendency to harmonious unity, the carving of the altarpiece grandly invades the parietal surface of the chapel, constituting a "golden cave", and hence the rest of the interior, making it a whole church of gold
. Thus, based on the historical and documentary, visual and interpretative reading of the carving of the Church of Jesus of Aveiro, we will evaluate the compromise, as syntheses, between the archite ctural sobriety of the building and the exuberance of
the interior of the Church of Jesus, materializing in a visible way the Invisible - invisibilia per visibiliaLeitura comentada ao espaço da igreja de Jesus como metáfora celeste e o seu impacto no crente, em particular os aveirenses que a frequentavam.
Neste contexto, pretende - se entender a evolução estética, formal e morfológica da talha da Igreja de Jesus como espaço integrado no Barroco Nacional [Igrejas forradas de ouro]. Partindo assim, do conceito de “Igreja Forrada a Ouro” faremos a singela homenagem a um investigador e autor da obra singular “A Talha em Portugal”, publicada
em 1962 (h á 54 anos), o Professor Robert Smith , que se passa a citar: “segundo a tendência barroca à harmoniosa unidade, a talha do retábulo grandiosamente invade a superfície parietal da capela, constituindo uma “caverna dourada”, e daí o resto do interior, tornando - o uma igreja (toda de ouro) (Smith, 1962 p: 89).
Da leitura histórica e documental, visual e interpretativa da talha da Igreja de Jesus de Aveiro faremos, como síntese, a avalição acerca do compromisso existente entre a
sobriedade arquitetônica do edifício e a exuberância do interior da Igreja de Jesus materializando -se de forma visível o invisível – invisibilia per visibili
Turbulent structures in unsteady wall-bounded flow subject to temporal acceleration
No full textDirect numerical simulations (DNS) of a transient turbulent channel flow subject to constant temporal acceleration have been performed with a final Reynolds number of \Retau=800. The response of turbulent structures to the temporal acceleration is investigated. A significant delay in the response of turbulent flow is observed in various turbulent properties. It is found that the response of turbulent flow to temporal acceleration consists of two stages: the destruction of the initial \emph{old} turbulence, followed by the generation of \emph{new} turbulence associated with a higher number. The \emph{new} turbulence is much stronger than the \emph{old} turbulence
Sustainability In Engineering And Engineering Education: A Comparative Study Of German And Saudi Arabian Industries
Full text linkSustainability has become a major concern in the fields of engineering and engineering education. Organizations such as UNESCO have defined goals for sustainable development in engineering. As engineers design, develop, and implement products and processes that impact the environment and society, their role in promoting sustainable development is vital. Addressing sustainability in engineering curriculum is needed to equip engineers with the knowledge, skills, and attitudes required to develop sustainable solutions in their respective areas, and it involves merging the teaching of technical skills with a systems-based approach that considers the broader environmental and economical context of engineering. This 1 Corresponding Author Talha Bin Asad [email protected] requires collaboration between different disciplines and stakeholders, including engineers, educators, policymakers, and industry. This study investigates the industry practices regarding sustainability goals and measures in two countries. Another point of inquiry is to find practical recommendations from engineers and project managers to inform engineering education curriculum in terms of knowledge and awareness of sustainability. Qualitative case study protocol was followed in this research, and participants from Germany and Saudi Arabia were interviewed online. Thematic coding was performed to extract meaning making descriptions from the interview transcripts. In response to the interview prompts, the participants shared their perspectives of sustainability in their area of engineering. Their recommendations towards the curriculum development included making UN sustainability goals a part of engineering curriculum, while still teaching students to adopt a ‘lean product development approach’ in their course projects, so that they learn the practical implementation of sustainability in engineering projects as well as in life
Identifying lake longer-term dynamics via fuzzy relations and non-linear Kalman filters
No full textDimirovski, Georgi M. (Dogus Author) -- Dinibütün, Abdurrahman Talha (Dogus Author) -- Conference full title: 1999 European Control Conference, ECC 1999; Karlsruhe; Germany; 31 August 1999 through 3 September 1999A novel simulation modelling technique that may be used to reconstruct or predict longer-term water level dynamics of lakes and reservoirs has been elaborated. On the grounds of the conservation law and a kind of self-regulation property of these lakes, by using Kalman filters for the unmeasurable part of hydrologic-cycle dynamical path and output observation equation in traditional and in fuzzy-relational a simulation modelling technique was developed that is believed to have wide applicability. It has been applied to reconstruct successfully the behaviour of Ohridean and Prespanean Lakes during various time periods, despite the available records are interrupted, uncertain and unreliable due to historical circumstances
Knowledge and technology transfer: Novel results while teaching advanced courses
Full text linkDimirovski, Georgi M. (Dogus Author) -- Dinibütün, Abdurrahman Talha (Dogus Author)Graduate studies in fields of Engineering typically include advanced control theory. in turn, these courses enhance both academic and applied research, hence contributing to combined knowledge and technology transfer, in particular if supported by industry as well. This paper reports on such fruitful experiences at our universities through the math-analytical back-stepping and state-feedback control design methodologies. Computer simulation and laboratory experiments have demonstrated these controller designs possess quality performances, which are comparable with the other designs for the same applications.16th Triennial World Congress of International, Federation of Automatic Control, IFAC 2005, Location: , Czech Republic
Metal–organic framework based non-precious metal electrocatalysts for the oxygen reduction reaction
Full text linkProton-exchange membrane fuel cells (PEMFCs) are devices capable of converting the chemical energy stored in hydrogen into electrical energy for several applications. Their high energy conversion efficiency and environmentally friendly emissions have designated them as viable candidates to replace fossil fuel-based technologies, particularly in transportation applications. However, the high cost associated with the platinum-based catalyst required to drive the sluggish kinetics of the cathodic oxygen reduction reaction (ORR) have rendered these devices impractical on a large scale. To address this, the development of non-platinum group metal (non-PGM) catalysts is a research area of great relevance.
This thesis serves to (1) address the mechanism surrounding non-PGM electrocatalysts and provide a method to understand the structure-property relationship, and (2) study strategies in the synthesis of non-PGM electrocatalyst for greater homogeneity in the as-made active structures.
The first part of this thesis work involves the use of the zeolitic imidazolate framework ZIF-8 as a model precursor to understanding the role of temperature on the conversion of metal organic frameworks (MOFs) to an active catalyst. The experimental data together with the DFT calculations suggests that the proximity of carbon-encapsulated neighboring iron structures can play a role in activating surface carbon atoms leading to the cleavage of the OOH bond, a key step in the ORR.
In the second part of this thesis, the use of cadmium as a sacrificial metal instead of the widely-used zinc is presented. The use of cadmium allows for the synthesis of an active non-PGM electrocatalyst at a lower pyrolysis temperature, resulting in an abundance of single atom sites. Furthermore, at a higher pyrolysis temperature, the catalyst synthesized with cadmium as the sacrificial metal exhibited noteworthy activity in both a three-electrode half-cell test and a membrane electrode assembly (MEA) study.
Lastly, a MOF immobilization strategy is introduced which involved the use of Ketjen black carbon as a support to effectively anchor the MOF precursors prior to thermal treatment. This would allow for a greater dispersion of the single atom metal sites and curb sintering during thermal treatment. It was demonstrated that there was an exclusive formation of single atom iron structures after the pyrolysis using this strategy.
The work in this thesis provides the basis for a fresh outlook on the current work in the area of non-PGM electrocatalysts for the cathodic ORR. Through this work, we seek to expand on the understanding of these catalyst materials on a fundamental level and to propose strategies to design and develop highly active catalysts.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2023-05-01The student, Talha Al-Zoubi, accepted the attached license on 2021-03-28 at 19:46.The student, Talha Al-Zoubi, submitted this Dissertation for approval on 2021-03-28 at 19:57.This Dissertation was approved for publication on 2021-04-08 at 07:44.DSpace SAF Submission Ingestion Package generated from Vireo submission #16217 on 2021-09-16 at 20:07:53Made available in DSpace on 2021-09-17T04:04:05Z (GMT).

Program management in regional social housing construction programs
No full textThe Netherlands currently suffers from a housing shortage, which cannot be solved by the traditional project-based approach of realizing new homes. Under a visible trend of a project-transcending, programmatic approach within the construction sector, various housing associations, municipalities and market parties are united in an inter-organizational collaboration to combat the shortage of social rental housing. These have led to various regional social housing construction programs, the Bouwstroom (Dutch translation for construction flow). Since program management requires an appropriate approach for each specific program, there is a need to better understand and further develop the current application of this management concept in the Bouwstroom programs for this context. Program managers should guard against a too one-sided focus on either control management, because this is too robust for a programmatic collaboration, or interaction management, because this leads to too slow progression and expensive ideas. The solution is to complement the two approaches with each other, in which an appropriate ratio of both approaches is context-dependent. To counter interaction or control related challenges, mixed strategies should be applied over time and a right structure is necessary in the organization. Furthermore, the literature speaks of six attributes of effective program management: 1) the vision, 2) priority focus, 3) planning framework, 4) governance, 5) coordination and 6) adaption. These attributes must be applied appropriately for each program for program management to function effectively. Two representative case study programs, WoonST and Bouwstroom Noord, are analyzed. A cross-case study has made it clear that the current application of program management in both cases leads to external interaction challenges in particular. Where the internal parties are aligned and motivated, there is still a hindrance from parties that are not part of the Program Management Office, but still influence the course. This results in the municipalities being limited in their role to speed up the processes. In order to create more value of the programs, the major challenges need to be mitigated. Multiple interaction-type strategies suggested from the literature are validated to mitigate them, several of which have not been applied before. However, they still need to be balanced with control strategies, of which those proposed from the literature mostly score poorly. This indicates that the need for additional complementary control measures is still present and does not seem to be satisfied by the study's findings. This study confirms the theory that program managers should maintain an appropriate interaction and control focus, despite a short-term detriment to the process. In addition, this research shows that program managers must continue to learn. By analyzing strategies from your own program, programs from other Bouwstroom programs and even programs from different contexts, and reflecting on a specific context, unique challenges can be approached more accurately. New strategies should be learned in order to approach unique challenges more accurately.Civil Engineering | Construction Management and Engineerin
Opportunity charging: A case study based on real-life public transportation scenarios
No full textEmissions caused by regular vehicles with fossil fuels are problematic for the environment. The integration of electric vehicles in public transportation can potentially cause zero emissions. This paper will focus on the implementation of electric buses together with inductive chargers at bus stops. These chargers will charge the bus battery while passengers enter or leave the bus. This is also known as opportunity charging. Opportunity charging could result in the easier implementation of electric buses within public transportation since it solves the range problem that electric vehicles have. The first parts of this paper will provide a discussion about the powertrain model made in Mat- lab/Simulink. The powertrain model input is the driving cycles from the Arnhem Trolleybus data. The outputs are the energy consumption during the driving cycle and the state of charge of the bus battery. The opportunity charger will then be added to the model to analyze the effects of opportunity charging on the bus. The implementation of opportunity charging increases the operational range of the electric bus, while also lowering the energy consumption. The chargers will operate at a high power rating which spans from 100 kW to 200 kW. These power ratings could cause congestion of the grid. This is why the feasibility of PV systems at bus stops is analyzed using a PV model. A PV system is insufficient to power the chargers on its own. The PV system can still provide a significant percentage of the charger power demand.Electrical Engineering | Electrical Power Engineerin
Decision making in toc-product-mix selection VIA fuzzy cost function optimization
No full textDinibütün, Abdurrahman Talha (Dogus Author), Dimirovski, Georgi M. (Dogus Author)This paper presents an innovated fuzzy decision-making under Theory-of-Constraints for the product-mix problem using a smooth logistic membership function for finding out fuzziness patterns in disparate level of satisfaction. Agility of this membership function when applied to real-world product-mix problems has been validated. This contribution is believed to provide a robust, quantified monitoring of the level of satisfaction among decision-makers and to calibrate these levels of satisfaction against decision-makers’ expectations, thus providing a computational intelligence procedure. Inefficiency of traditional linear programming in handling multiple-bottleneck problem through the traditional Theory-of-Constraints concept is discussed via an illustrative example

No full textAbstract: With the expansion of technologies and increasing use of internet, the online market is blooming at a noticeable rate. Online Shopping is now a well-known term for the people of all ages. Businesses are constantly trying to find new strategies that can help them gain loyal customers, in order to avoid the considerable cost of attracting new customers. The competition among online companies is to increase sale by getting new customers, make their shopping cart full, and make customers repurchase. To do this companies need to have an idea on cluster of their target customer and customers’ demand. The present study seeks to provide a deeper understanding of the brand experience phenomenon in online context by investigating the impact of e-brand experience on e-satisfaction and e- loyalty. This thesis analyzes if service quality has any significant impact on brand loyalty, where customer satisfaction is used as an indicator for brand loyalty. Furthermore, this thesis aims to measure the impact that service quality has on customer satisfaction, as well as if service quality has any significant effect on brand loyalty. This study also aspires to further explore the correlation between the different factors that cause a consumer to become loyal to a brand.
