To help designers in writing OCL constraints, we have to construct systems that can generate some of these constraints. This might be done by instantiating templates, by combining prefabricated parts, or by more general computation. Such generated specifications will often contain redundancies that reduce their readability. In this paper, we explore the possibilities of simplifying OCL formulae...

Traumatic defects are mostly accompanied by hard and soft tissue loss. This report describes the surgical and prosthetic treatment of a patient with post-traumatic mandibular defect. A split-thickness skin graft was performed prior to implant placement and prefabricated acrylic stent was placed to hold the graft in place. The esthetic and functional demands of the patient were fulfilled by impl...

Abstract Prefabricated construction is attracting increasing interest in recent years, since this method has various advantages as compared to the cast-in-situ method, such less time, higher quality control and reduced environmental impact. As a typical type of prefabricated structures, precast segmental column (PSC) been used substructure accelerate speed bridges. This paper reviews performanc...

Prefabricated slab has been widely used in the global construction industry due to energy saving, environmental protection, and good economic advantages. In this paper, a new type of fully prefabricated staggered flip-down without cast-in-situ operation proposed. First, experiments were carried out on slab. The structural performance was compared with slabs composite same specification. experim...

INTRODUCTION Flap innervation by neoaxonogenesis is a promising field of investigation. The authors evaluated the possibility of innervating an acellular collagen scaffold as component of a potential prefabricated flap. MATERIALS AND METHODS Collagen matrix sheets were implanted around the femoral bundle of a murine model to produce two flaps on proximal and distal nerve stumps based on a flo...
