Abstract:

BACKGROUND Nowadays, the use of computer aided design / computer aided manufacturing (CAD / CAM) in fabricating indirect restoration such as onlay, crown and bridge has increased tremendously. However, there is lack of clinical information and evidence on current material and fabrication techniques of CAD / CAM post and core. This paper describes the classification of the post and core system and review current perspectives on recent development of CAD / CAM post and core.

Abstract:

Previously published evidence has established major clinical benefits from using computer-aided design, computer-aided manufacturing, and additive manufacturing to produce patient-specific devices. These include cutting guides, drilling guides, positioning guides, and implants. However, custom devices produced using these methods are still not in routine use, particularly by the UK National Health Service. Oft-cited reasons for this slow uptake include the following: a higher up-front cost than conventionally fabricated devices, material-choice uncertainty, and a lack of long-term follow-up du

Abstract:

In computer-aided architectural design, words are an underemployed source of information. Through a series of case studies, we deduced a design annotation data model. All entities in this model can be captured from the design draft, except one: the word relation. Therefore, a system was developed that generates word graphs using single words from the draft as input. The system searches for semantic relations between words and for new intermediate words that can connect two existing words. The system has filters that select only those graphs that are considered interesting by the designers. The

Abstract Additive manufacturing has enabled the fabrication of complex structures such as cellular structures. Although numerous design frameworks have been proposed for cellular structures, their effectiveness was limited owing to the use of B-rep-based representation. To address the limitations in previous research, this study proposes an implicit-based computer-aided design framework customized for additively manufactured functionally graded cellular structures (AM-FGCSs). The proposed design framework effectively aids in both single- and multiscale structural optimization for designing FGC

Abstract:

Plate heat exchangers (PHEs) have significant potential to improve energy efficiency in the process industries. However, realizing their full potential to achieve such energy savings requires a systematic approach to screen the many options available. Thus, this work presents a generalized novel approach for the optimal design of both gasket and welded plate heat exchangers, with different plate geometries and flow configurations. A new design method coupled with an optimization framework is proposed to obtain the optimal solution with minimum total transfer area by setting up a series of rela

Abstract:

Computational fluid dynamics has been extensively used for fluid flow simulation and thus guiding the flow control device design. However, computational fluid dynamics simulation requires explicit geometry input and complicated solver setup, which is a barrier in case of the cyclic computer-aided design/computational fluid dynamics integrated design process. Tedious human interventions are inevitable to make up the gap. To fix this issue, this work proposed a theoretical framework where the computational fluid dynamics solver setup can be intelligently assisted by the simulation intent capture

Abstract:

Evolutionary structural testing has been researched and promising results have been presented. However, it has hardly been applied to real-world complex systems and as such, little is known about the scalability, applicability and acceptability of it in an industrial setting. The European project EvoTest (IST-33472) team has been working from 2006 till 2009 to improve this situation and this paper informs about the results. We start with an overview of tools and techniques which we have developed for automated evolutionary structural testing. Subsequently, we describe the empirical setup used

Several aspects are addressed, covering CAD (Computer-Aided Design) modelling systems to CAE (Computer-Aided Engineering) solutions, in terms of analysis and validation of mechanical resistance calculations. Therefore, structural mechanics fundamental concepts and mechanics of materials are also addressed. Particular focus is given on the development of curricula components related to Computer-Aided Design and Manufactu

Abstract:

Purpose Digital practices of facility management (FM) are undergoing transformation. Several Nordic countries have ambitious hospital-building projects, driven by large public clients with long-term experience of operating complex building campuses. There is thus an opportunity for creating state-of-the-art digital FM. This paper aims to investigate the role of digital FM in new hospital projects in Scandinavia. Design/methodology/approach Based on a literature review, a framework of understanding of digital FM in hospital operation is established. Two longitudinal cases are presented and anal

Problem. Special attention is paid to maintaining tower cranes in good working order and serviceable condition through their proper operation. Unfortunately, violation of the operating rules can lead to an emergency situation. In this case, both the crane operator and other workers on the construction site may be injured. And in some cases even to death. Therefore, the development of measures for safe operation is very important. It is also important to ensure sufficient strength of the load-bearing steel structures, which make up the bulk of the tower cranes, the breakdown of which leads to s

Abstract As the physical size of semiconductor devices continues to be aggressively scaled down, feedback field-effect transistors (FBFET) with a positive feedback mechanism among a few promising steep switching devices have received attention as next-generation switching devices. Conventional FBFETs have been studied to explore their device performance. However, this has been restricted to the case of single FBFET; basic circuit designs with FBFETs have not been investigated extensively. In this work, we propose an inverter circuit design with silicon-on-insulator (SOI) FBFETs; we verified th

Structure-based and computer-aided drug design approaches are commonly considered to have been successful in the fields of cancer and antiviral drug discovery but not as much for antibacterial drug development. The search for novel anti-tuberculosis agents is indeed an emblematic example of this trend. Although huge efforts, by consortiums and groups worldwide, dramatically increased the structural coverage of the Mycobacterium tuberculosis proteome, the vast majority of candidate drugs included in clinical trials during the last decade were issued from phenotypic screenings on whole mycobacte

Abstract:

AbstractPerformance assessment at early stages of buildings design is complicated by an inherent lack of information on the design and the uncertainty in how a building design may evolve to a final design. This pilot study reports on an initial quantification of such uncertainty associated with building energy performance and develops a method for informing decision makers of the risks in early design decisions under this uncertainty. Two case studies of building design decision situations under this uncertainty are explored along with using two different energy modeling tools: a reduced-order
