We propose a method in this paper which improves the speed and effects of visualization process in product concept design. In digital product design software, the preview mode and render mode are for simple usage without optimization. The designers need to adjust the view by themselves. To improve the preview result for more usability, we defined a method based on aesthetical rules. The rule defines the virtual camera used in design software in which how target object will be shown. Then it is used to compute the movement of the camera in virtual environment. The movement path is computed automatically among different preview angles for even different preview targets.

Computer technology has affected architectural studies as well as other professions. Architectural tools are used in every stage of the design and their primary goals are transferring and sharing the ideas of the architects’ mind. Nevertheless, in the early design phase, digital design tools remain ineffective in terms of idea development. Current design software and modeling tools are insufficient for the architect to quickly share ideas and generate alternative suggestions for fast sketching and modeling. In this paper, a mobile design application is developed. It aims to support open-ended design thinking and to be fast and effective in terms of improving ideas. It is based on augmented reality and it works on mobile phones. In order to evaluate the application, a set of images consisting of tall buildings are shown to users. Then they are asked to model a similar form of their own. At the end, results are assessed with a questionnaire. Using the obtained data, the effectiveness of the digital mobile tool in the early design stage is discussed.

Проектирование сооружений очистки воды имеет многовековую историю. В настоящее время в мировом проектном сообществе сложились практически единые технологические схемы очистки природной воды до уровня питьевой и очистки хозяйственно-бытовых сточных вод. В области очистки воды в профессиональном сообществе идет интенсивный обмен идеями, технологиями, промышленными продуктами. В последнее время активно развиваются математические методы расчета блоков сооружений, используются методы цифрового (компьютерного) проектирования. Для сложных проектов в первую очередь выполняются предпроектные работы. Методы проектирования сооружений очистки воды остаются по сути своей эвристическими, и для одной и той же постановки задач может быть предложен ряд конструктивных решений. Цифровая среда проектирования позволяет решать новые задачи, прежде всего проектировать очистные сооружения, оптимальные не только по показателям качества воды и другим техническим параметрам, но одновременно, если это возможно, и по экономической эффективности. Предлагается метод разработки предпроекта с использованием многовариантных математических процедур, которые позволяют приблизиться к оптимальному сочетанию технических и финансовых показателей будущего сооружения очистки воды. Designing water treatment facilities has a centuries-old history. At present, the world project community has developed practically unified process flow schemes for natural water treatment to the drinking water quality and domestic wastewater treatment. The professional community practices an intensive exchange of ideas, technologies, and industrial products in the field of water purification. Recently, mathematical methods for calculating module structures have been actively developing, methods of digital (computer) design are used. For complex projects, first of all, pre-project work is carried out. Methods for designing water treatment facilities remain inherently heuristic, and a number of design solutions can be proposed for the same problem statement. The digital design environment provides for tackling new problems, first of all, for designing treatment facilities that are optimal not only in terms of the water quality and other technical parameters, but at the same time, if possible, in terms of the economic efficiency. A method is proposed for the development of a pre-design using multivariate mathematical procedures that allow approaching the optimal combination of technical and financial indicators of the future water treatment facility.

This paper presents a scalable Fully-digital differential analog voltage comparator designed in Semi-Conductor Laboratory (SCL) 180[Formula: see text]nm complementary metal-oxide semiconductor technology. The proposed design is based on a digital design approach and is easily configurable to lower technology nodes. This design methodology makes the circuit less sensitive to process variations and takes fewer design efforts suitable for Systems-on-a-Chips (SOCs) application. The proposed circuit is designed and simulated in Cadence Virtuoso Analog Design Environment at the supply voltage ranging from 1[Formula: see text]V to 1.8[Formula: see text]V. The fully-digital analog voltage comparator has been synthesized using Synopsys Design Vision and auto-placed & auto-routed using Synopsys IC Compiler. This proposed comparator has a resolution of up to 7-bit at a supply voltage of 1.8[Formula: see text]V and a worst-case operating frequency of about 750 MHz at the TT corner. The obtained value of the offset voltage and delay is 0.55[Formula: see text]mV and 0.72 ns, respectively. The simulated results have shown that the power dissipation of the proposed scalable analog voltage comparator is [Formula: see text][Formula: see text]V and [Formula: see text][Formula: see text]V supply voltage, respectively. Also, the RC extracted post-layout simulations have been implemented to verify the performance, which does not affect the results much.

PurposeHighly sophisticated digital technologies have distanced architects and designers from intimate and immediate hand-drawing practices. Meanwhile the changes they rapidly bring come with undetected changes in cultural and social norms regarding the built environment. The growing dependence on computers calls for a more holistic, socially inclusive and place-responsive design practice. This paper aims to shed light on what we are losing in the design process as we rapidly transition to communicate architecture using digital media. The authors contemplate the paradigms in which the human body and physical objects still play an important role in today's design environment.Design/methodology/approachThe paper looks at current trends in developing and establishing “computer imaging” within architectural education, and the architectural profession through parametric design and the area of sustainability. In order to reveal novel and hybrid ways of architectural image-making, it also looks into art forms that already experiment with bodily practices in design by taking an artisanal animation project as a case study.FindingsThe renewed longing for craft, haptic environments, tactile experiences and hand-crafted artifacts and artworks that engage the senses can be exemplified with the success of the documentary Last Dance on the Main, an animated film on the endangered layers of human presence in one of Montreal's downtown neighborhoods. The open possibilities for creative hybridizations between the handmade and the digital in architecture practice and education are exposed.Originality/valueThe influence of film on the perception and consequent design of cities is well documented. There is little literature, however, on how the materiality and process of artisanal film animation can provide alternative, if not additional, insights on how to communicate various aspects of the built environment, particularly those rooted in the human body. Furthermore, handmade film explores a broader understanding of sustainability, which includes considerations for social and cultural contexts.

Two Degree Of Freedom

Mechanisms are used in many devices to move a rigid body through a finite sequence of prescribed locations. The most commonly used mechanisms are four-bar planar mechanisms that move an object in one plane in space. Spatial mechanisms allow motion in three-dimensions (3D), however, to date they are rarely implemented in industry in great part due to the inherent visualization and design challenges involved. Nevertheless, they do provide promise as a practical solution to spatial motion generation and therefore remain an active area of research. Spatial 4C mechanisms are two degree-of-freedom kinematic closed-chains consisting of four rigid links simply connected in series by cylindrical (C) joints. A cylindrical joint is a two degree-of-freedom joint, which allows translation and rotation about a line in space. This paper describes a synthesis process for the design of 4C spatial mechanisms in a virtual environment. Virtual reality allows the user to view and interact with digital models in a more intuitive way than using the traditional human-computer interface (HCI). The software developed as part of this research also allows multiple users to network and share the designed mechanism. Networking tools have the potential to greatly enhance communication between members of the design team at different industrial sites and therefore reduce design costs. This software presents the first effort to provide a three-dimensional digital design environment for the design of spatial 4C mechanisms.
