Managing Accessibility- The Configurational Approach to the Inclusive Design of Urban Spaces

This paper concerns the theme of the universal accessibility to urban spaces, proposing the contribution of configurational approach to their inclusive design. Born in the first Nineties on the roots of the efforts and the studies for reducing material and architectural barriers for disabled people, such discipline extends its sphere and purposes so as to mitigate the effects of spatial exclusion of a wider and wider variety of human categories, up to virtually include any potential urban user. Several questions persuade that a merely functional approach, essentially based on the position of the located activities, cannot be said satisfying： only a configurational approach can account for the effects of the grid configuration on the actual accessibility of its spaces. Our research focuses on Italian urban settlements, which appear as ideal case studies, due to the typical consistency of their urban spaces, which, especially in the inner historical cores, are densely build, geometrically irregular and hence generally far from actually providing a universal material accessibility. Here the impedance of space is much more than a theoretical hypothesis and concrete interventions are generally requested to eliminate or reduce its barriers and to make space actually and safely usable. Rather than at indicating the technical solution of single urban problems, which of course are strongly different each other, the research aims at defining a method suitable for any local context. Such method, integrating into a reliable tool the configurational vision with the functional and interactional approach, will provide a hierarchy of urban spaces with reference to the necessity of their universal accessibility.

It is known that every linear code can be used to construct the secret sharing schemes. Since the code of a symmetric （V, k, λ）-design is a linear code, this study is about the secret sharing schemes based on C of Fp-code C of asymmetric （v, k, λ）-design.

PIV Investigations of Flow Patterns in the Entrance Configuration of Plate-fin Heat Exchanger

Flow characteristics in the entrance of plate-fin heat exchanger have been investigated by means of particle image velocimetry (PIV). The flow field was measured using the two-frame cross-correlation technique. Streamline and velocity contour graphs at different cross-sections were obtained in the experiment. The experimental results indicate that flow maldistribution in the conventional header is very serious, while the improved header configuration with punched baffle can effectively improve the uniformity. The flow maldistribution parameter in plate-fin heat exchanger has been reduced from 1.21 to 0.21, and the ratio of the maximum velocity to the minimum is reduced from 23.2 to 1.8 by install-ing the punched baffle. The results suggest room for the optimum design of plate-fin heat exchanger.

＂Universal Design＂ Approach for the Participation of the Disabled in Urban Life

Disability can occur to anyone and anyone can have difficulties in fulfilling daily activities in a certain part of their lives. Accessibility is a crucial matter and a basic human right for the disabled people in order to join the urban life. For this reason, the physical environment must be set, starting with the planning and design stage, in a form that can satisfy the utility and accessibility requirements of disabled people. One of the most important recent concepts to enable accessible and useful spaces for the disabled is the ＂universal design＂. Nowadays, even though there is an increase in the number of scientific publications, meetings and decisions taken, the regulatory process on our current living environment is developing slowly regarding the physical accessibility. At this point, the most important role regarding the handling of social and political paradigms of disability, addressing different users, application of the principals of universal design and creating knowledge in order to increase social awareness belongs to the departments of universities that offer design courses. The subject of the study in this context is to determine the contents and the proportion of the courses （compulsory and elective） related to ＂universal design and ＂disability design＂, which will ensure our living environment to be accessible and independently utilized for everyone, in the course plan of the architecture, interior architecture, urban planning and landscape architecture departments in Turkey.

Integrating Universal Design Standards and Building Information Modeling at the Conceptual Design Stage of Buildings

A projection of the Canadian population shows that in 2024 one in five Canadians will be over 65 years old. This shift forces designers to consider the entire lifetime of occupants during the design of new buildings. Universal Design (UD), which is a design that accommodates all people to the greatest extent possible and aging in place design that is deeply rooted in the principles of UD, aim to house people irrespective of their age, ability, and chronic health conditions. Building Information Modeling (BIM) significantly helps advance the development of the Architecture, Engineering, and Construction (AEC) industry in a more collaborative and automated way. Integrating BIM and UD allows designers to incorporate UD standards easily and efficiently at the conceptual design stage of buildings by using the functionalities and capabilities of BIM tools. Therefore, this study presents the development of an automated computer model to facilitate the adoption of UD standards and processes. The novelty highlighted in this model resides in the creation of an automated method that employs a newly created plug-in and databases to assist designers to incorporate UD standards at the conceptual stage in a timely and cost-effective manner. Furthermore, the study introduces the methodology consisting of collecting, categorizing, and storing data from various universal design and accessible design guidelines in the developed databases and developing new plug-ins in BIM tool to link the developed databases in order to automate the process of retrieving necessary information and components to help designers and owners select optimal design alternatives based on their predefined criteria.

Qualitative System Dynamics as a Tool in Accessible Design

A description of the Systems Dynamics paradigm is given and the reduced Qualitative System Dynamics (QSD) form explained. A simple example is given to illustrate the diagram construction. The principles of states (levels), rates and feedback loops are outlined. The QSD method is used to address the problem of accessibility by using human control of automation as an example, and applying the QSD method to evaluate the effects of the researcher and user in the de- sign of an accessible artefact. This simple automation model illustrates what can be found out from such a picture, in this indicating how the feedback from users has an influence on the time to deliver such designs.

Design for the Elderly： Housing and Re-arrangements-- Case Studies in Istanbul

As a consequence of developing technology, various medical developments and environmental factors, the population of elderly people has been rising. Future predictions show a rising trend for designing for the elderly and. In order for seniors to be able to appear in community life, to be self-sufficient and live their lives independently, supportive environments are required. Being able to sustain seniors＇ lives has to be seen as a civic right and architectural design should be considered as a tool to get these rights. As linked to everyday living, homes should be a starting point to get these rights. Being in the core of everyday activities, the spaces in dwellings should meet life-span design criteria. Fundamental principles lying under the aspects of design, dimensions, details, colors and symbols of supportive environments should not be affected from generation gap and senium and should rather aim at this user group. These fundamentals can briefly be listed as, change as less as possible, design for self-sufficiency, communication and socialization. In the paper, the focus is on these fundamental design principles for residential spaces, together with the research of reflections of factors, affecting health, security and mobility deriving from mobility disabilities, perception and memory weakening, specifically to bathroom design.

3D Printing Technology for Buildings＇ Accessibility： The Tactile Map for MTE Museum in Pavia

3D printing technology is an innovative manufacturing technology used in several disciplines, whose number and diversity are growing day by day. The development of devices to improve the accessibility of buildings and urban spaces for people with disabilities through 3D priming technology is still not broadly explored. The present study is focused on filling this gap, with the realization of a tactile map of the MTE （Museum of Electrical Technology） of the University of Pavia （Italy） for blind and visually impaired people. The tactile map represents the building plan with all the information to guide the visit. The device is the result of a research process which is made by several steps and experimental tests, aimed at setting the best 3D priming profiles to meet all the requirements of the end-users. This paper describes methods and strategies applied to reach these goals： it underlines the social and technical approaches, the experimental phases and its possible future developments.

A Nodal Electricity Market Design Based on Regulated Access to Transmission Network

Accomodation of power system constraints with the market mechanism is encountered as a major challenge along the way toward implementation of different electricity market designs. Allocation of fixe or flow-dependent inter-zone trading capacities by the PX （power exchange） can not be accepted unreservedly. The paper is meant to show that a nodal electricity market design that is based on bids for local energy and a regulated transmission access including allocation of ＂entry-exit＂ transmission capacity would be the desired solution. The market players could easily optimize their portfolio while the TSOs （transmission system operators） are requested to mobilize the network＇s in-built flexibility to increase the cross zonal capacity. In the proposed market design, the PX＇s allocation of trading capacity is clearly separate from the TSO＇s management of the power system operational constraint5. Clear operator roles would enlarge access to electricity market as well as market integration of variable RESs （renewable energy sources） that are critically dependent on short notice access to regionat markets,

Towards Smart, Sustainable, Accessible and Inclusive City for Persons with Disability by Taking into Account Checklists Tools

The main characteristics of potential smart cities in the future, smart citizens, smart energy, smart buildings, smart mobility, smart technology, smart healthcare, smart infrastructure, smart governance and education, and finally smart security are the aspects of smart cities. In the smart city, smart accessible infrastructure creates an inclusive environment for people with disabilities, in which they can integrate into the community and enjoy their civil, cultural, political, social and economic rights and entitlements. The aim of this study is to integrate disabled people into society so that they can actively participate in society and lead to a normal life. An integrated approach is needed to ensure that people with disabilities are not left alone. A combination of mainstreaming and targeted action is required for all interventions. People with disabilities have the same basic needs as everyone else: health protection and treatment, basic services, housing and income. Targeted intervention measures need to complement disability mainstreaming by addressing specific needs identified by general responses, including such interventions need not add materially to the overall cost, especially if the requirements of the maximum number of users are considered in the initial planning. This paper recommends how we can use an appropriate design checklist as a guide for our initial architectural concept and smart city planning to facilities reasonably accessible for people with disabilities in private and public buildings, making our cities smarter and more inclusive and helping to improve the quality of life for all people, especially people with disabilities.

A Non-parametric Gradient-Based Shape Optimization Approach for Solving Inverse Problems in Directed Self-Assemblyof Block Copolymers

We consider the inverse problem of finding guiding pattern shapes that result in desired self-assembly morphologies of block copolymer melts.Specifically,we model polymer selfassembly using the self-consistent field theory and derive,in a non-parametric setting,the sensitivity of the dissimilarity between the desired and the actual morphologies to arbitrary perturbations in the guiding pattern shape.The sensitivity is then used for the optimization of the confining pattern shapes such that the dissimilarity between the desired and the actual morphologies is minimized.The efficiency and robustness of the proposed gradient-based algorithm are demonstrated in a number of examples related to templating vertical interconnect accesses(VIA).
