Authors: Li Lin Lin , Li Guo Zhong , Hu Jian Rui
Published: April 2014

This paper studied the impact of borax, citric acid, carboxymethyl cellulose and gelatin on retarded time and mechanical properties of gypsum foamed materials. Scanning electron microscopy (SEM) was conducted to investigate microstructure of gypsum and phase composition of substances on plaster surface as well as the retardation mechanisms. The result showed that when the content of citric acid reached 0.2%-0.3%, the setting time of sample significantly prolonged, but the strength of samples significantly reduced and had defoaming effect. When the content of borax was more than 0.5%, retarding effect was obvious, but flexural strength of samples reduced to 1.22 MPa, it could not meet the requirement of the national standards on the properties of building gypsum. When the content of carboxymethy cellulose was 0.3%, the retarding effect was obvious, but the strength loss was serious, and the consistency of gypsum slurry significantly increased. When the content of gelatin was 0.2%, the comprehensive retarding effect was good, the strength reduction was smaller, so choose gelatin as a retarder in this paper.

Authors: Sauki Arina , Azizi A. , Alias Nur Hashimah , Ghazali Nurul Aimi , Mohd T.A.T. , Najmi M.N.M.
Published: April 2014

Cement strength must be carefully maintained so that the cement is able to sustain formation stresses without failing. Such a mechanical failure in a cement sheath can cause a loss of annular isolation. A synthetic polymer cement retarder has been designed to provide extended pumping times for cement slurries, while having minimal effect on compressive strength development. However, it is difficult to select a retarder that can suit a wide range of field conditions. Fluid loss control can also be affected by the addition of a retarder, especially at high temperatures. Addition of retarder sometimes may increase the viscosity and pumping pressure of the slurry and may result in fracturing of the hydrocarbon bearing zone and costly job failure. The main idea for this study is to determine whether Agarwood waste from distillation process (AGW) can be used as a retarder in oil well cement with excellent compressive strength development. The compressive strength developments were evaluated at different curing time and particle sizes of AGW which are 90 μm, 150μm and 250μm. The performance of AGW slurries were compared with commercial retarder slurry. Apart from that, chemical analysis on AGW was conducted by using X-ray Fluorescent (XRF) to determine the presence of cementations component in this material. All cement testing procedures should follow API recommended specification 10B standard. From the results obtained, the performance of 250 μm of AGW is better than commercial retarder by 10% increment in the development of cement strength.

Through the help of FCFS algorithm which was utilized in Task Queue, as well as Multi-Level Feedback for decision making and job scheduling, the minimization of idle times during the process is expected. Moreover in case of any tardiness of machines, system immediately sends feedback to renovate the machine station. Basically the novel RFID technology (Radio Frequency Identification) is used for any data transaction between system structures, including: reading, storing and categorizing the information to each tag that attached to pieces. Besides, the software has been developed for managing the global database. All in all the current system which is based on optimal suggestion of algorithms is under implementation in the CIM laboratory of Eastern Mediterranean University.

The Government Pharmaceutical Organization (GPO) is one of the largest pharmaceutical manufacturers in Thailand. GPO provides many medicinal products such as tablets and capsules to increase drug access to the Thai population through public hospitals and retail stores. Orders from these customers are accumulated and signal drug production. However, backorder shipments occur frequently and are estimated to worth about 180 million baths (or 6 million USD) a year. Initial study shows that the packing process behaves as a bottleneck, causing delays in the production and consequently to the drug shipments. The packing process utilizes multiple machines with different speeds and capacities. Moreover, instead of setup time in other manufacturing processes, drug production including the packing process requires a clearance process after each job—which is critical in pharmaceutical industry to reduce the risk of cross-contamination between drugs. The clearance time depends on the drug type of the next job. This paper presents a problem of job scheduling using parallel non-identical machines with sequence dependent clearance times. The objective is to minimize the total makespan. The mathematical model of the problem is a mixed integer/binary program. A numerical example from actual packing jobs is used to illustrate its application and solved by Excel Solver software.

The inverse kinematics is very important in robotic application in the case of known object position. This paper explains about the inverse kinematics of right arm robot NAO based on the corner detection of a Chinese character image. The transformation coordinate system from image input of Chinese character to the robot NAO’s frame acceptable writing is needed. In order to control the right arm of robot NAO to write a Chinese character well, it is necessary to make a proper set of the RShoulderRoll angle q1 and the RElbowRoll angle q2, respectively. At first, the thinning processing, corner detection and depth-searching are employed to recognize a Chinese character. Due to the robot NAO just has three fingers, dust the position of the marker or pen-brush must be suitable of its. The experiment results achieve a better demonstration of recognition and handwriting for simple Chinese characters with less than 5 strokes.

Reliable quantification techniques for graphene oxide (GO) and graphene nanosheets (GNs) in ESD rubber product are limited. We demonstrated an effective ultrasonically−assisted latex mixing (ULM) technique for dispersion of GO and GNs at low concentration (0.5, 1.0 and 1.5 part per hundred of rubber; phr) in natural rubber latex (NRL) to produce NR/GO and NR/GNs conductive thin film. The filled−NR composites were prepared by ULM, followed by latex dipping coagulation. The morphologies from transmittance electron microscopy (TEM) of stabilized GO and GNs dispersion showed successfully dispersion and exfoliation in NR matrix. Compared to pure NR, the tensile strengths of NR/GO and NR/GNs (1.5 phr) increased by ~58% and ~32%, respectively, while there were decreased in the %elongation at break and were no significant change in the force at break. In case of studying the electrical properties, sheet resistances of filled−NR composites declined with the incorporation of GO and GNs. However, the NR composite with 1.5 phr of GNs showed the best conductivity.

Aiming at edge information easily lost in impulse noise filtering, an algorithm for high noise density is proposed in this paper. Firstly, pixels contaminated can be detected by the characteristic of their grey and some information about every pixel and its neighborhood can be got. Secondly, by a judgment of the detail and a selection of the optimal neighborhood, two traditional filter methods are used to reduce the noise density and obtain more information of the contaminated pixels. Finally, the edge judgment based on double-window is added to preserve more edge information. Experiment shows that for impulse noise, whether the low density or the high density, the proposed algorithm can obtain more satisfactory result with a lower RMSE (Root of Mean Square Error) and a higher EPI (Edge Preserved Index).

Published: April 2014

Because fatigue monitoring based on the image of the non-contact measurement is single and low accuracy, a novelty driver fatigue monitoring system based on multivariate hierarchical Bayesian network is proposed. The system mainly includes four modules following: face region detecting, eyelid closure judging, head region positioning, and fatigue analyzing. The eye region is positioned precisely by the method of gray projection function, the binary image which contains the whole eye information using self-adapting threshold method is obtained, and then driver fatigue monitoring system based on hierarchical Bayesian network is used to evaluate the fatigue level of the driver. The experimental results show that the fatigue monitoring accuracy is up to 90% in specific conditions, it’s effective to improve the detection accuracy compared to the other method.
