Wood is one of the most common materials in this type of constructs due to the great availability of this material in the territory during Brazil’s colonization period.
According to the authors [9] elastic stiffness it is one of the most important determinations when using structural reinforcements with distinct materials.
The approach of this property is consistent because it is a sample composed of distinct materials (timber containing the structural reinforcement of epoxy resin).

The application of the projection pursuit model of the particle swarm algorithm on the investment decision Deng Li1, a , Luo Fangqiong2,b 1Department of Finance and Economics, Liuzhou Teachers College Liuzhou, Guangxi, 545004, China 2 Department of Mathematics and Computer Science, Liuzhou Teachers College Liuzhou, Guangxi, 545004, China a youerli@163.com, bluofangqiong123@163.com Keywords: projection pursuit model; particle swarm algorithm; investment decision Abstract.
There were m projection to be chosen for example, A1，A2，…，Am, the investment was carried out for projection Ai, and the ai billion could be spent, and the profits was ci billion, in order to establish the optimal investment plan, the mathematics could be expressed as follows: (13) ， (14) Where xi equal to 1, the investment should be used to Ai otherwise no investment was carried out; this research used the value: B=19，the investing corresponding relation (Ai，ai，ci), i=1，2，3 (unit: billion), which could be expressed as follows: (15) The application of the PPC model based on PSO on the projection investment decision The material in paper [1] was applied; the decision was confirmed
