Experimental Tests for the Analysis of the Load-Bearing Capacity of an Internal Slab-Column Connection after its Punching at Various Positions of the Column
Authors: Wieczorek Barbara
Published: June 2014

Normally, in practice the situation of a slab-column structure is rarely analyzed after the occurrence of a local breakdown. Catastrophes which have happened so far indicate the need of considering in detail slab-column connections in reinforced concrete structures in order to prevent progressive collapses. Some suggestions concerning the prevention of such situations are to be found merely in CSA A23.3-04 and ACI 318. This problem is not dealt with in the Polish Standards, nor in the Eurocodes.
The paper presents the results of investigations performed on a model of slab-column connections in the scale 1:1. Three variants of the position of the column in relation to the centre of the slab have been considered: the axial position, the position in an unidirectional eccentricity, and in bidirectional eccentricity. The tests were performed in two phases, viz. "Phase 1" preceding the punching and "Phase II" after punching to the complete destruction of the connection. The aim of these investigations was to find out how far any additional bending moment resulting from the eccentric effect of the load affects the value of the destructive load imposed on the connection after its punching. The obtained results permitted to determine the relations between the exerted load and the displacement of the column in time, and also to determine the values of the force at which the rupture of the bars above the column had taken place. The results of these tests were compared with the standard.

TFT-LCD Spot-Type Defect Detection in Module Process
Authors: Guo Bo , Hu Guo Qing , Yang Guang Yong
Published: June 2014

In this paper we present a global approach for the automatic inspection of spot-type defects in TFT-LCD module process. The proposed method is based on a global image reconstruction scheme using the Fourier transform. Since TFT-LCD surface has the statistical and periodic texture, the isotropic spread of frequency components in the power spectrum space forms the shape approximate to a circle. By computing the convolution between the Fourier transform result and a ideal low pass filter (ILPF) , we can remove the TFT-LCD periodic and repetitive patterns using the inverse Fourier transform. In the restored image, the global structurally textured background is eliminated and the spot-type defects are preserved. This converts the difficult defect detection in TFT-LCD images into a simple segmentation problem. The spot-type defects are classified into general point defects and spot Mura defects .The experimental results from point defects and spot Mura defects have shown the efficacy of the proposed method.

Authors: Chaowalit Orawan , Sornil Ohm
Published: June 2014

With the advancement in the Internet technology, customers can easily share opinions on services and products in forms of reviews. There can be large amounts of reviews for popular products. Manually summarizing those reviews for important issues is a daunting task. Automatic opinion summarization is a solution to the problem. The task is more complicated for reviews written in Thai language. Thai words are written continuously without space, there is no symbol to signify the end of a sentence, and many reviews are written informally, thus accurate word identification and linguistic annotation cannot be relied upon. This research proposes a novel technique to generate abstractive summaries of customer reviews written in Thai language. The proposed technique, which consists of the local and the global models, is evaluated using actual reviews of fifty randomly selected products from a popular cosmetic website. The results show that the local model outperforms the other model and the two baseline methods both quantitatively and qualitatively.
