Software developers continue to face considerable challenges designing, implementing, and maintaining software systems despite steady advances in software engineering (SE). The software engineering literature contains numerous tool designs that aim to help developers perform complex information-intensive tasks. Regardless of the particular problems these tools aim to solve, they often address f...

quality function development (qfd) is a planning tools used to fulfill customer expectation and qfd is a systematic process to translating customer requirement (whats) into technical description (hows). qfd aims to maximize customer satisfactions related to enterprise satisfaction. the inherent fuzziness of relationships in qfd modeling justifies the use of fuzzy regression for estimating the r...

This thesis is a study into an engineering technology that enables us to investigate the cognitive aspects of systems. Where previous techniques have focused on individual human roles undertaking defined tasks, this work develops engineering technologies to understand the cognitive contribution of the human team participating in the system and how the deployment of machine decision making techn...

currently autografts are gold standards for craniomaxillofacial bone regeneration. but autografts have some limitations. bone tissue engineering has been introduced to overcome these limitations. it consist three components: stem cells, growth factor, and scaffold. scaffold provides an environment for bone growth and simplifies cell adhesion, differentiation and proliferation. in this review, a...
