A multi-heuristic schedule repair model for schedule conflict resolution is presented and its application in repairing the schedules of a prefabrication plant is described in this paper. The model combines heuristic strategies with Genetic Algorithms to repair schedules with resource constraints. The GA determines the “best” sequence of resolving schedule disturbances using heuristic rules sele...

Private developers in Nigeria’s housing development industry still face challenges of increasing stock, with a current deficit 20 million units. Prefabrication, known, yet unpopular construction method, has witnessed low usage. The effect system characteristics on user acceptance prefabrication technology is examined through the Perceived Usefulness (PU), amongst private Nigerian development. p...

The present clinical case history report describes an interdisciplinary treatment protocol that combines maxillary tumor resection with immediate reconstruction to achieve functional rehabilitation. A fibula flap that received four dental implants and a split-thickness graft epithelial layer was prefabricated for a 31-year-old man. The flap was designed so that it could be adapted to fit in dif...

An assembly approach for microdevice construction using prefabricated microfluidic components is presented. Although microfluidic systems are convenient platforms for biological assays, their use in the life sciences is still limited mainly due to the high-level fabrication expertise required for construction. This approach involves prefabrication of individual microfluidic assembly blocks (MAB...

Unlike ASICs, FPGAs have routing fabrics that are pre-manufactured. And because of this prefabrication, FPGAs hardly can achieve high clock frequencies which offered by ASICs. Thus, there is a need for better FPGA timing performance. And design automation or computer-aided design (CAD) tools for field programmable gate arrays (FPGAs) have played a very critical role over the past decades for FP...

In this paper, a new building concept for multi-family lightweight timber frame housing is proposed. This concept combines party walls, floors and façade elements ensuring comfort levels equal or better than currently encountered in typical Belgian heavy constructions. Low frequency behaviour and prefabrication potential were the key points in the design process of the new wall and floor types....

This paper introduces properties and object-oriented models of software agents. Based on literature on agent technology, properties of agents are explained systematically. Agent systems are understood as a software architecture type. To simplify and refine this complex topic, special models decribing properties of re-usable agents are discussed. This leads to the prefabrication for mobility, co...

When traditional flap techniques are not feasible, we apply flap prefabrication, which is more complicated and sophisticated but supplies large and thin flaps. There are some disadvantages to the technique that require improvement, such as venous congestion after flap transfer, which requires months for neoangiogenesis and necessitates a vascular carrier. Here, the author presents a new techniq...

The exact location of a single dopant atom in a nanostructure can influence or fully determine the functionality of highly scaled transistors or spin-based devices. We demonstrate here a noninvasive spatial metrology technique, based on the microscopic modeling of three electrical measurements on a single-atom (phosphorus in silicon) spin qubit device: hyperfine coupling, ground state energy, a...
