RAPID prototyping, COMPUTER-aided design, CURVATURE, SURFACE analysis, DIGITAL elevation models, and ARCHITECTURAL designs
We study the difficult problem of deciding if parts of a freeform surface can be generated, or approximately generated, by the motion of a planar profile through space. While this task is basic for understanding the geometry of shapes as well as highly relevant for manufacturing and building construction, previous approaches were confined to special cases like kinematic surfaces or 'moulding' surfaces. The general case remained unsolved so far. We approach this problem by a combination of local and global methods: curve analysis with regard to 'movability', curve comparison by common substring search in curvature plots, an exhaustive search through all planar cuts enhanced by quick rejection procedures, the ordering of candidate profiles and finally, global optimization. The main applications of our method are digital reconstruction of CAD models exhibiting sweep patches, and aiding in manufacturing freeform surfaces by pointing out those parts which can be approximated by sweeps.

REAL estate development, ARCHITECTURAL designs, and COLLEGE graduates
The article presents diverse real estate development designs created by 2006 British architecture graduates. By using rapid prototyping techniques, University College student Tobias Klein created the Chapel of Our Lady de Regla, an inverted chapel slotted into an existing courtyard to meet the need for space to bury the dead. Westminster University graduate Gillian Lambert designed a studio house for the weather-obsessed architect. Edinburgh University graduate David Eland developed a design for a pharmaceutical research facility.
HOTELS, BUSINESS travelers, EXHIBITIONS, GUEST rooms, and ARCHITECTURAL designs
The article discusses the project, Hotel of Tomorrow (HOT), that was created and led by Gettys, a hospitality design firm in Chicago, Illinois and "Hospitality Design" magazine which asked participants to design the hotel guestroom of 2025 for the business traveler, without monetary restraints and by using the same architecture available today. The two-day ideation began with "visioning: figuring out the big idea," according to HOT ideation leader Matt Phillips of Phillips + Co., a strategizing firm in Chicago that helps companies think differently about their brands and products. Highlights include "My Spa," the bathroom that brings the hotel spa to the guest; "Dynamic Window Imagery," a technologically advanced hotel window that can make a bad day look beautiful; and "Instant Room Service," a pneumatic and robotic meal delivery and preparation service that operates faster than humans. With the HOT ideation complete, seven themes emerged: efficiency, escape, wellness, personalization, connectivity, ecology, and other. The next step was prototyping. The first HOT exhibit will be built for the HD2005 Expo and Conference, from May 5-7 in the Sands Exposition center in Las Vegas, Nevada.

PROTOTYPES, INDUSTRIAL design, ARCHITECTURAL designs, and MULTIDISCIPLINARY design optimization
The article presents an interview with George Kembel, executive director at Hasso Plattner Institute of Design. When asked about the new philosophy of design, Kembel refers to human-centered approach in which they use a culture of prototyping and multidisciplinary teams of design. Kembel explains that the approach focuses on design thinking that gives engineers greater motivation. He adds that a major shift in teaching design also occurs in which innovations fall between different disciplines.

COMPUTER software development, SIMULATION methods & models, ENGINEERING, EMBEDDED computer systems, ARCHITECTURAL designs, and DIGITAL signal processing
Today, designers of next-generation embedded processors and software are increasingly faced with short product lifetimes. The resulting time-to-market constraints are contradicting the continually growing processor complexity. Nevertheless, an extensive design-space exploration and product verification is indispensable for a successful market launch. In the last decade, instruction-set simulators have become an essential development tool for the design of new programmable architectures. Consequently, the simulator performance is a key factor for the overall design efficiency. Motivated by the extremely poor performance of commonly used interpretive simulators, research work on fast compiled instruction-set simulation was started ten years ago. However, due to the restrictiveness of the compiled technique, it has not been able to push through in commercial products. In this paper, we tie up with our previous research on retargetable, compiled simulation techniques, and provide a discussion about their benefits and limitations using a particular compiled scheme, static scheduling, as an example. As a conclusion, we eventually present a novel retargetable simulation technique, which combines the performance of traditional compiled simulators with the flexibility of interpretive simulation. This technique is not limited to any class of architectures or applications and can be utilized from architecture exploration up to end-user software development. We demonstrate workflow and applicability of the so-called just-in-time cache-compiled simulation technique by means of state-of-the-art real-world architectures. [ABSTRACT FROM AUTHOR]
