Due to that the human error has great influence on the project risk, human reliability analysis (HRA) has been paid much attention in many engineering projects.
For management of construction materials, the construction materials which are in large amount use should purchased by competitive bidding, which can prevent purchasing inferior materials for saving cost.
For those construction materials whose quality or sources may be unstable, different batches materials should be piled up separately and be tested by supervisor at any time.
Once there are some quality problem, it should be reported to the construction department and the materials should be changed to qualified materials.
Materials supply and consumption should be coordinated with each other.

Experimental Study on Diesel Engine Intake Ports with Reverse Engineering Technology Li JIANGa, Zi-Yu WANGb,*, Xiu-Wei CHENGc and Chao-Yang LUd China North Engine Research Institute, Beichen, Tianjin 300400, China ajiangyushi586@sina.com, bzealyouth2002@126.com, cxiuweicheng2008@126.com, dluchaoyang@sina.com *Corresponding author Keywords: Reverse Engineering, Diesel, Intake Ports.
A intake port was developed for a four-valve diesel engine with reverse engineering technology, and different core boxes of intake port were made respectively by different measureing and manufacturing method, and were investigated in the steady-flow test with the original cylinder head of the diesel engine.
The Reverse-engineering of Intake Port Data Acquisition and Processing Profiling measurement in reverse engineering is important link of data acquisition, model reconstruction and the quality of surface rendering.
After joining together the three-dimensional structure of deformation due to cut sample material, can not have local structure cohesion.

Damage probability is a new concept in modern engineering design.
However, the general information of material can be provided to engineers by studying the damage probability of a set of specimens.
The conception of structural reliability has been widely recognized and adopted in engineering.
Experimental Research and Analysis The raw materials for concrete were selected carefully in experimental study.

Current bone tissue engineering is using in vitro expanded mesenchymal stem cells (i.e. bone marrow stromal cells) and synthetic scaffolding materials to produce synthetic bone substitutes comparable to autologous bone.
Increasing data is showing that osteoinductive synthetic materials can attract mesenchymal stem cells in non-osseous tissues and form ectopic bone.
In vivo bone tissue engineering, by using osteoinductive synthetic materials to produce bone in soft tissues, would be another approach to produce synthetic "autologous" bone for bone repair.
Material and Methods Preparation of materials The osteoinductive Ca-P ceramics were prepared by using the wet-synthetic calcium phosphate powder through the H2O2 foaming method and sintering at 1100 o C for 3 hours.
