The multi-detector, multi-ray source switching function ray DR / ICT integration testing system has been developed, which covers international strongly development of ray digital imaging detection technology. Development of the test system forms the ray digital imaging product development capability of independent property serialization, and provides the conditions for the ray imaging detection...

From the analogue of Böhm’s Theorem proved for the typed lambda calculus, without product types and with them, it is inferred that every cartesian closed category that satisfies an equality between arrows not satisfied in free cartesian closed categories must be a preorder. A new proof is given here of these results, which were obtained previously by Richard Statman and Alex K. Simpson. Mathema...

The effective cost management during the conceptual design phase of a product is essential to develop a product with minimum cost and desired quality. The integration of the methodologies of quality function deployment (QFD), value engineering (VE) and target costing (TC) could be applied to the continuous improvement of any product during product development. To optimize customer satisfaction ...

this paper proposes a three-step method for solving nonlinear volterra integralequations system. the proposed method convents the system to a (3 × 3)nonlinear block system and then by solving this nonlinear system we ndapproximate solution of nonlinear volterra integral equations system. to showthe advantages of our method some numerical examples are presented.

Product innovation is a process of knowledge and technology resource integration. This paper mainly researches the process and realization of product integrated innovation based on function. Several function integrated methods are presented, and the principle solutions are selected and evaluated based on extend effect model. The process model for product integrated innovation is proposed, which...
