These studies use construction materials with standardized properties.
It presents a comparison between two families of beams (small beams and normal beams) out of BA with same materials what makes it possible to study the scale effect.
As the composite being integrated in the matrix, the physical interface with concrete still remains permanent and the adherence between the two materials is perfect.

Part level feature includes general feature and material feature.
Material feature is the description of the materials used for the blade part.
The attribute of general feature is composed of part name, part code, material mark, blade categories, blank categories, part overall dimension, part weight, production categories, technical requirements, designer and other information. 2) Material Feature Material Feature refers to the information aggregate of blade material performance (such as material trademark, material feature, the main body tissue of the materials that is used for blade, material varieties and specification), heat treatment mode and surface treatment methods, and so on.

Abstract: In recent years, the mobile internet is deployed rapidly in large-scale.
The digital format learning materials are stored or transmitted with mobile computing technologies via the mobile internet, so that the learning could conducts without restrictions on time and place with smart mobile devices, and become easier and universal accessible.
The intelligent capability is required on self-optimized searching, for example, on one hand the searching need to quickly hit the desired answer considering all possible angles from the learning aspects, including the relevant concept, examples, discussions, testing, etc, on another hand, the background analysis according to the search content and rate could be enabled and presented to the learner combined with all relevant materials as focused topic selections which could help the learner to review, and even be a good reference for others.
(2) General design The M-Learning system is including several sub-systems e.g. the account, message, classes, materials, question and answer, and schedule management sub-systems.

Introduction
The correlation of the electronic and magnetic properties of colossal magnetoresistance (CMR) materials with structural properties has been a topic of enormous research activity over the last few years.
Today, the most common bolometer temperature sensing materials are vanadium oxides (VOx) have TCR above 4 %/K and amorphous silicon (α-Si) with TCR up to about 3%/K at room temperature (RT) [2,3].
The values of residual compressive strain in the films due to the substrate-material mismatch have been calculated using the Eq.1
