design, utopia, alteration, prototyping, progetto, and alterazione
The purpose of this paper is to re-explore the relationship between utopia and architecture, trying first and foremost to challenge the way utopia has been conceived by architectural thought: i.e., as the prefiguration of a future seen as an ‘otherness’ distinct from the present, as far as the totality of its spatial, social, and political dimensions are concerned. Such vision – as we will argue – turns out to be deeply linked to a design logic of ‘projection’ and ‘prescription’; this, however, is not the only possible logic of design. Through a reflection upon some contemporary architectural practices, we will try to highlight a new horizon for design action, in which even utopia abandons its traditional ‘projective’ role and takes on a new meaning: rather than being the non-place of a possible future, utopia stands for what doesn’t have place in the present but can emerge from its alteration. Such notion of utopia as a form of ‘situated critique’, in a concrete space and time, helps to dig more deeply into the political potential of many contemporary forms of architectural and urban design. Il proposito di questo contributo è tornare a esplorare la relazione tra utopia e architettura, cercando innanzitutto di mettere in questione il modo in cui l’utopia è stata concepita tradizionalmente nel pensiero architettonico: vale a dire, come la prefigurazione di un futuro concepito come alterità rispetto al presente, nella totalità delle sue dimensioni spaziali, sociali e politiche. Tale visione - come si cercherà di illustrare - è intimamente legata a una certa logica “proiettiva” e “prescrittiva” che, tuttavia, non è l’unica logica possibile del progetto. Attraverso una riflessione su alcuni modi del progetto di architettura contemporaneo, si cercherà infatti di mettere in evidenza una nuova logica progettuale, in cui anche l’utopia abbandona il suo carattere proiettivo tradizionale per acquisire un nuovo senso: non più il non-luogo di un futuro possibile, bensì ciò che non ha luogo nel presente e che può tuttavia emergere dalla sua alterazione. Questa nozione di utopia come “critica situata” concretamente in uno spazio e in un tempo aiuta a comprendere più in profondità il potenziale politico di molte delle forme contemporanee di progetto architettonico e urbano.

1. INTRODUCTION With computing devices peppering nearly every aspect of our lives, how people interact with these technologies is critically important to all computing fields. In fact, failure to properly [...] Given the ubiquity of interfaces on computing devices, it is essential for future Information Systems (IS) professionals to understand the ramifications of good user interface (UI) design. This article provides instructions on how to efficiently and effectively teach IS students about 'fit,' a Human-Computer Interaction (HCI) concept, through a paper prototyping activity. Although easy to explain, the concept of 'fit' can be difficult to understand without repeated practice. Practically, designing 'fit' into UIs can be cost-prohibitive because working prototypes are often beyond students' technical skillset. Accordingly, based on principles of active learning, we show how to use paper prototyping to demonstrate 'fit' in a hands-on class exercise. We provide detailed stepby-step instructions to plan, setup, and present the exercise to guide students through the process of 'fit' in UI design. As a result of this activity, students are better able to employ both theoretical and practical applications of 'fit' in UI design and implementation. This exercise is applicable in any course that includes UI design, such as principles of HCI, systems analysis and design, software engineering, and project management.

Computer-aided design (CAD) and rapid prototyping (RP) are now a fundamental part of the professional practice of product design and are therefore essential skills for product design undergraduate students. This book provides students with all the tools needed to get to grips with the range of both CAD software and RP processes used in the industry.

Introduction: Rapid prototyping is a process by which threedimensional (3D) computerized surface models are converted into physical models. In this study, a 3D heart bio model was created using the rapid prototyping method and the accuracy of this heart model was assessed by clinicians. Methods: The two-dimensional images of normal heart from gated computed tomography scan datasets were used to create a 3D model of the heart. The slices were then processed using the software BioModroid and printed with the 3D printer. The evaluation of the model was performed by a questionnaire answered by four cardiothoracic surgeons, 12 cardiologists, five radiologists, and nine surgical registrars. Results: Eighty-six percent of the anatomy structures showed in this model scored 100% accuracy. Structures such as circumflex branch of left coronary artery, great cardiac vein, papillary muscle, and coronary sinus were each rated 77%, 70%, 70%, and 57% accurate. Among 30 clinicians, a total of 93% rated the model accuracy as good and above; 64% of the clinicians evaluated this model as an excellent teaching tool for anatomy class. As a visual aid for surgery or interventional procedures, the model was rated excellent (40%), good (50%), average (23%), and poor (3%); 70% of the clinicians scored the model as above average for training purpose. Overall, this 3D rapid prototyping cardiac model was rated as excellent (33%), good (50%), and average (17%). Conclusion: This 3D rapid prototyping heart model will be a valuable source of anatomical education and cardiac interventional management.

Microfluidic technologies have enormous potential to offer breakthrough solutions across a wide range of applications. However, the rate of scale-up and commercialization of these technologies has lagged significantly behind promising breakthrough developments in the lab, due at least in part to the problems presented by transitioning from benchtop fabrication methods to mass-manufacturing. In this work, we develop and validate a method to create functional microfluidic prototype devices using 3D printed masters in an industrial-scale roll-to-roll continuous casting process. There were no significant difference in mixing performance between the roll-to-roll cast devices and the PDMS controls in fluidic mixing tests. Furthermore, the casting process provided information on the suitability of the prototype microfluidic patterns for scale-up. This work represents an important step in the realization of high-volume prototyping and manufacturing of microfluidic patterns for use across a broad range of applications.

"Assessment to Enhance Air Force and Department of Defense Prototyping for the New Defense Strategy is the summary of a workshop convened by the Air Force Studies Board of the National Academies' National Research Council in September 2013 to enhance Air Force and Department of Defense (DoD) prototyping for the new defense strategy. This workshop examined of a wide range of prototyping issues, including individual recommendations for a renewed prototype program, application of prototyping as a tool for technology/system development and sustainment (including annual funding), and positive and negative effects of a renewed program. Prototyping has historically been of great benefit to the Air Force and DoD in terms of risk reduction and concept demonstration prior to system development, advancing new technologies, workforce enhancement and skills continuity between major acquisitions, dissuasion of adversaries by demonstrating capabilities, maintaining technological surprise through classified technologies, and an overarching strategy of overall risk reduction during austere budget environments. Over the last two decades, however, many issues with prototyping have arisen. For example, the definitions and terminology associated with prototyping have been convoluted and budgets for prototyping have been used as offsets to remedy budget shortfalls. Additionally, prototyping has been done with no strategic intent or context, and both government and industry have misused prototyping as a key tool in the DoD and defense industrial base. Assessment to Enhance Air Force and Department of Defense Prototyping for the New Defense Strategy envisions a prototyping program that encourages innovation in new concepts and approaches and provides a means to assess and reduce risk before commitment to major new programs."--Publisher's description.
Keywords Convolutional neural network; Hardware acceleration; Rapid system prototyping; Binarization; FPGA Abstract The huge model size and high computational complexity make emerging convolutional neural network (CNN) models unsuitable to deploy on current embedded or edge computing devices. Recently the binary neural network (BNN) is explored to help reduce network model size and avoid complex multiplication. In this paper, a binary network acceleration framework for rapid system prototyping is proposed to promote the deployment of CNNs on embedded devices. Firstly trainable scaling factors are adopted in binary network training to improve network accuracy performance. The hardware/software co-design framework supports various compact network structures such as residual block, 1 x 1 squeeze convolution layer, and depthwise separable convolution. With flexible network binarization and efficient hardware architecture optimization, the acceleration system is able to achieve over 2 TOPS throughput performance comparable to modern desktop GPU with much higher power efficiency.
