Towards an Architecture Operating as a Bio-Cyber-Physical System
No full textToday’s physical-digital continuum challenges designers and architects to envision architecture as a Bio-Cyber-Physical System that is operating as part of a larger ecosystem while addressing societal challenges with a broader understanding of sustainability in mind. This paper identifies current conditions, challenges and opportunities, while proposing an intercultural dialog toward achieving a better future. The purpose is to enlighten and explore the threshold where the physical interlaces the domain of immaterial flows of information as well as identify some of the digital and material design aspects shaping the multiple facets of bio-cyber-physical-systems in order to propose some possible solutions for current design challenges.History, Form & Aesthetic
Ambient UX for Cyber-Physical Spaces
No full textAmbient User Experience (Ambient UX) is a conceptual framework providing a strategy for design processes that target cyber-physical spaces. Such design processes interface Wireless Sensor-Actuator Networks (WSAN), Artificial Intelligence (AI), and physically built environments. For managing the complexity of such design processes and ensuring the development of a design facilitating users’ satisfaction, design approaches focused on experience and user activities linked to bio-cyber-physical feedback loops are needed. This paper points out how Ambient UX supports decision-making in a design process. It outlines the importance of mapping user experiences for cyber-physically enhanced environments by discussing design practices that can support this activity and presenting a representative case study implemented with students at TU Delft.History, Form & Aesthetic
Roll cage design and validation for a rally vehicle
No full textThe roll cage represents one of the most significant equipments for the personal protection in every sport car and in rally vehicles in particular. It is generally made of thin gauge pipes, joined together, to assemble a safety structure. This frame has to be designed in the way to absorb the kinetic energy during impacts reducing the risk of injuries for drivers and navigators. The design of an appropriate roll cage to be installed on a rally vehicle and its validation by Finite Elements methods represent the main motivation for this investigation. CAD frame was modelled by CATIA software using shell elements. Geometrical and material nonlinear FEM analysis was implemented by PAK code. Using experimental tests in displacement control conditions, critical forces on the structure were also determined. Numerical results were compared with experimental ones, permitting to refine the simulation model. Then, FEM provided the safety factor and all the information regarding the strength of acceptable materials. The CAD/FEM procedure, limiting the number of experimental tests, reduced cost and time requested for the design validation

Those differences are mainly manifested regarding its quality and quantity. The aim of this paper is to emphasize the importance of territorial distribution of the wood mass from the aspect of its use in the wood industry. The result of the research procedure is to point out certain parts of the Adriatic region, where the development of the wood industry can be promoted
Designing for Ambient UX: Design Framework for Managing User Experience within Systems of Enhanced Spaces
No full textThe research aims to contribute towards the field of User Interaction and Experience Design by proposing a design strategy and toolset to be applied within emerging projects for spaces enhanced by digitized services, based on an Ambient UX design approach. This particular design field deals with highly complex projects focused on user experience, which does not seem to be addressed appropriately with current tools employed in practices. Therefore, the research identified the need to expand current practices in the UX field by supporting them with the set of upgraded tools to be used as a backbone for structured design processes. In this context, design tools facilitate the creation of a common language between all parties and stakeholders involved in the design project for identifying and communicating user values.
The main overview of the tailored research methodology will be provided in this chapter, along with the main results derived from the research presented and discussed. The methodology comprises three main research areas: (1) hypothesis for a design strategy for Ambient UX, deriving from literature review; (2) verification of the Ambient UX framework hypothesis through practical design projects; and (3) analysis of UX value alignment tools and proposal for their upgrade
Material tests report - Wrapped Composite Joints project
No full textInterest in composites for application in Civil Engineering structures, has seen significant increase in recent years. From composite repairs on existing structures from concrete or structural steel, to composite decks in bridges or even structures made solely out of fibre reinforced composites, the structural industry is following the already existing trend in automotive and aerospace industry where composite solutions present a great potential that traces back to 1960’s. Within this framework the Wrapped Composite Joints project, under Dr. M. Pavlovic, attempts to bring the composites technology to jacket designs of offshore wind turbines and replace the traditional welding technology that is used for connecting the steel tubular members of the jacket frame. Higher stiffness, more sustainable and lightweight design due to reduced steel weight and most importantly higher fatigue resistance are just some of the benefits that the developing technology brings in the structure. Developing a new technology especially when a novel material solution is used, requires robust knowledge of the inherent material as well as bond properties. For this experimental testing series should take place along different structural levels. Goal of such experimental series is to investigate the capabilities of the material as well as the assembled components up to total failure.In the current Additional graduation work a coupon testing series comprising of different standard test methods, part of the Wrapped Composite joints project is presented. Aim of this study is the establishment of fundamental material elastic as well as fracture properties for the composite layup used in the project. Outcomes of the experimental study will be used as input for the realistic representation of the material and the bonded interface through Finite Element Models(FEM) of several scales, from small specimens to large and full scale Joints.Civil Engineerin
Limit analysis of masonry domes: the case of Hagia Sophia and Anime Sante
No full textThe conservation of cultural heritage is a challenge for the contemporary society. In recent
decades, significant resources have been allocated for the conservation and restoration of the
architectural heritage. Historical buildings were restored, protected and reinforced with the
intent to limit the risks of degradation, due to phenomena of structural damage and to external
factors such as differential settlements, earthquakes, etc. The wide diffusion of historic masonry
constructions in the Mediterranean basin requires reliable tools for the evaluation of their
structural safety.
Masonry domes represent an important part of the architectural heritage. However domes
haven’t been studied as much as other masonry structures. The collapses happened in recent
years, as a consequence of seismic actions or lack of maintenance, show the need of detailed
studies. Here a limit analysis (Milankovitch, 1907; Heymann, 1969; Livesley, 1992; Milani and
Cecchi, 2013) to the evaluation of the behavior of masonry domes is presented. An algorithm
based on the kinematic approach has been developed to evaluate the minimum collapse
multiplier and to determine the position of the hinges. The proposed method is compared with
some real cases: the collapse of Anime Sante Church in L’Aquila and the analysis developed
on Hagia Sofia in Istanbul. This comparison is useful to tune and validate the proposed method
Technical product risk assessment: Standards, integration in the erm model and uncertainty modeling
No full textEuropean Union has accomplished, through introducing New Approach to technical harmonization and standardization, a breakthrough in the field of technical products safety and in assessing their conformity, in such a manner that it integrated products safety requirements into the process of products development. This is achieved by quantifying risk levels with the aim of determining the scope of the required safety measures and systems. The theory of probability is used as a tool for modeling uncertainties in the assessment of that risk. In the last forty years are developed new mathematical theories have proven to be better at modeling uncertainty when we have not enough data about uncertainty events which is usually the case in product development. Bayesian networks based on modeling of subjective probability and Evidence networks based on Dempster-Shafer theory of belief functions proved to be an excellent tool for modeling uncertainty when we do not have enough information about all events aspect
