An enhanced dynamic hash TRIE algorithm for lexicon search

Information retrieval (IR) is essential to enterprise systems along with growing orders, customers and materials. In this article, an enhanced dynamic hash TRIE (eDH-TRIE) algorithm is proposed that can be used in a lexicon search in Chinese, Japanese and Korean (CJK) segmentation and in URL identification. In particular, the eDH-TRIE algorithm is suitable for Unicode retrieval. The Auto-Array algorithm and Hash-Array algorithm are proposed to handle the auxiliary memory allocation; the former changes its size on demand without redundant restructuring, and the latter replaces linked lists with arrays, saving the overhead of memory. Comparative experiments show that the Auto-Array algorithm and Hash-Array algorithm have better spatial performance; they can be used in a multitude of situations. The eDH-TRIE is evaluated for both speed and storage and compared with the naïve DH-TRIE algorithms. The experiments show that the eDH-TRIE algorithm performs better. These algorithms reduce memory overheads and speed up IR.

CAFTA-DR Effects on FDI Inflows,Growth, and Distribution of the Workforce in Costa Rica: A System Dynamics Approach

As regional trading arrangements have spread, enlarged, and deepened over the last decades, the study of the relation between trade agreements and foreign direct investment (FDI) still presents difficulties due to the multi-dimensional character of such relationships. This article attempts to shed new light on how some of the Central American Free Trade (CAFTA) policies will impact FDI inflows on the manufacturing and agricultural sectors in Costa Rica. Specifically, we look at how the growth and distribution of the workforce is affected by the treaty. The results show that the agreement provisions will have a positive effect on FDI. From these results it is possible to estimate that in the long run, the implementation of CAFTA has a higher probability of generating the intended benefits. System dynamics modeling is used in this article.
