Abstract
Digital fabrication represents innovative, computer-controlled processes and technologies with the potential to expand the boundaries of conventional construction. Their use in construction is currently restricted to complex and iconic structures, but the growth potential is large. This paper aims to investigate the environmental opportunities of digital fabrication methods, particularly when applied to complex concrete geometries. A case study of a novel robotic additive process that is applied to a wall structure is evaluated with the Life Cycle Assessment (LCA) method. The results of the assessment demonstrate that digital fabrication provides environmental benefits when applied to complex structures. The results also confirm that additional complexity is achieved through digital fabrication without additional environmental costs. This study provides a quantitative argument to position digital fabrication at the beginning of a new era, which is often called the Digital Age in many other disciplines. [ABSTRACT FROM AUTHOR]

Abstract
Ecological awareness has spurred a renewed interest in hybrid electrical vehicles (HEV), because of their ability to combine the drive power of a combustion engine with that of electrical machines. PMSM's notoriously offer large torque/weight ratios and are therefore particularly well suited for inclusion in HEV drivetrains, where the available space is in general strictly limited. The virtual prototyping and optimizing of PMSM for HEV drive trains is, however, a repetitive and computer intensive task. This paper presents a automated methodology aiming at reducing to a minimum the design time by means of a systematic approach and parallel computing. [ABSTRACT FROM AUTHOR]

Abstract
A Computer-Aided Prototyping System (CAPS) helps to automate the early stages of software design, supports system management and aids in controlling a system's evolution. The Prototype System Description Language (PDSL) integrates the tools in CAPS so that the designer can work from a real-time schedule and generate an executable Ada model automatically. This study works with a prototype having embedded software characteristics, hard real-time constraints, multiple and predefined hardware interfaces, and complex requirements. The Ada prototype processes tactical data from multiple interfaces in real time. CAPS, used with the Transportable Applications Environment Plus windowing package, generates the Ada code, which is then run on a Sun 3. This prototype currently serves as a test model for computer-aided software design research and in the investigation of deadlock detection and prevention at the design level.

Abstract
Purpose – This feature article aims to review state-of-the-art developments in additive manufacture, in particular, 4D printing. It discusses what it is, what research has been carried out and maps potential applications and its future impact. Design/methodology/approach – The article first defines additive manufacturing technologies and goes on to describe the state-of-the-art. Following which the paper examines several case studies and maps a trend that shows an emergence of 4D printing. Findings – The case studies highlight a particular specialization within additive manufacture where the use of adaptive, biomimetic composites can be programmed to reshape, or have embedded properties or functionality that transform themselves when subjected to external stimuli. Originality/value – This paper discusses the state-of-the-art of additive manufacture, discussing strategies that can be used to reduce the print process (such as through kinematics); and the use of smart materials where parts adapt themselves in response to the surrounding environment supporting the notion of self-assemblies.

The design and development of analog/mixed-signal (AMS) integrated circuits (ICs) is becoming increasingly expensive, complex, and lengthy. Rapid prototyping and emulation of analog ICs will be significant in the design and testing of complex analog systems. A new approach, Programmable ANalog Device Array (PANDA) that maps any AMS design problem to a transistor-level programmable hardware, is proposed. This approach enables fast system level validation and a reduction in post-silicon bugs, minimizing design risk and cost. The unique features of the approach include: 1) transistor-level programmability that emulates each transistor behavior in an analog design, achieving very fine granularity of reconfiguration; 2) programmable switches that are treated as a design component during analog transistor emulating, and optimized with the reconfiguration matrix; and 3) compensation of ac performance degradation through boosting the bias current. Based on these principles, a digitally controlled PANDA platform is designed at 45 nm node that can map AMS modules across 22–90 nm technology nodes. A systematic emulation approach to map any analog transistor to 45 nm PANDA cell is proposed, which achieves transistor level matching accuracy of less than 5% for ID and less than 10% for Rout and Gm. Circuit level analog metrics of a voltage-controlled oscillator (VCO) emulated by PANDA, match to those of the original designs in 22 and 90 nm nodes with less than a 5% error. Several other 90 and 22 nm analog blocks are successfully emulated by the 45 nm PANDA platform, including a folded-cascode operational amplifier and a sample-and-hold module (S/H).

Abstract
The application of rapid prototyping in fabricating a non-assembly, multi-articulated robotic hand with inserts is presented in this paper. The development of robotic systems that have all necessary components inserted, with no assembly required, and ready to function when the manufacturing process is complete is quite attractive. Layered manufacturing, in particular stereolithography, can provide a means to do this. Stereolithography produces a solid plastic prototype via a manufacturing procedure where three-dimensional solid models are constructed layer upon layer by the fusion of material under computer control. An important aspect of the rapid prototype method used in this research is that multi-jointed systems can be fabricated in one step, without requiring assembly, while maintaining the desired joint mobility. This document presents the design and techniques for part insertion into a non-assembly, multi-articulated, dexterous finger prototype built with stereolithography. [ABSTRACT FROM AUTHOR]

Abstract
Computer-aided software prototyping and automation may help improve software productivity and reliability. Software prototyping helps customers understand and critique proposed systems while exploring alternative computer solutions that are time- and cost efficient. Speedy, accurate and inexpensive development becomes a necessity because prototypes are simple efficient models of future systems. They can also rely on different hardware or system software than the resulting program. Automation requires simple and clear mathematical models, and a standard set of abstract data types to form a machine representation of a standard prototyping language. The future prototyping tools may require a whole separate language combining the flexibility of an interpreted language with the capacity for selectively declaring compile-time constraints as consistent refinements. By formulating standards, the computer industry will help maintain a set of development standard tools that make software more reusable.

Abstract
One way to implement an automated hospital information system is through the use of rapid prototyping of user interfaces. Such a system can overcome one of the main problems of automation, the difference between users needs and expectations and the limitations of designed systems. Prototyping allows the problems to be worked out in a scaled-down model of the system, thereby saving considerable time and money. Artificial intelligence can be of use in a prototype system because of its noted capabilities with user interface development. The non-algorithmic nature of artificial intelligence allows it to use declarative programming to enhance user interface capabilities.

Abstract
The article discusses the three different technologies required for creating hybrid, multimaterial home fabbers. Fabbers are machines that rapidly create useful items on demand from computer generated design specifications. The technologies needed for the realization of fabbers are from solid-freeform fabrication called fused deposition modeling (FDM), from direct-writing technologies called pen writing and inkjet printing. FDM directly deposits materials in a continuous stream on a base. Pen-based machines are used to fabricate circuits using several passive and electronic materials at low temperatures. Inkjets are the cheapest systems and is the fastest-growing segment of the rapid prototyping market.

Current CAD systems have dedicated functionalities to model weld beads, but it is often cumbersome to use these systems. This study presents a method to analyze the geometry of assemblies of B-Rep models to automatically identify possible welds among the parts using prediction rules. Adjacent faces are detected, and Boolean operators on planar loops are used to identify bead paths. Beads are then split in homogeneous portions based on the topology of the connected parts. The main goals of this study are to increase the speed of the welding definition process and to benefit applications such as the cost estimation of steelwork products. Cost estimates are based on the shape, the length and the dimension of each weld bead. Some industrial examples are presented to show the benefits in terms of time savings and accuracy to the estimation process. [ABSTRACT FROM AUTHOR]
