The Performance of Permanent Magnet Core of Reducing Sag Voltage in Personal Computer (PC)
Authors: Ys H , Simanjuntak A D 
Published: August 2019

Abstract
The power quality has a significant effect on all system devices. The voltage factors are usually modulated caused by the excessive load changes which produce a sag voltage. One of the techniques used to reduce the voltage sag is to design a Cuk converter with PI controller coupled with two inductances (L) at the Cuk converter in order to make a non-ideal transformer with a permanent magnet core made by ferrite material. The experimental results revealed that, the non-ideal transformer with a permanent magnetic core would stabilizes the input voltage on personal computer (PC), thus the sag voltage can be minimalized. From the experiment, the optimum results were obtained with top gap was 1mm and the bottom gap was 6mm. It can be concluded that by using a ferrite core magnet with high coercivity, the output voltage can be stabilized thus there will be no sag at the input voltage on the PC.

Authors: Havanapan P , Phungthanom N 
Published: August 2019

Abstract
Peptidomic analysis coupled with mass spectrometry identification was employed to investigate the constitutively expressed peptides in latex serum Phytophthora-resistant rubber tree (Hevea brasiliensis), BPM24. The utilization of proteins and peptides as a strategy to study new methods can lead to a therapeutic application. However, a high-efficiency method to extract peptides from latex serum is not well established. After optimization of latex serum isolation from natural rubber latex, using of lysis solution for peptide extraction exhibited superior serum peptide recovery than using other chemical reagents. Ultrafiltration followed by solid-phase extraction was selected to achieve high extraction yield of low molecular weight proteins and peptides. Mass spectrometric and bioinformatics analysis characterized and predicted the identified protein and peptide contents. All latex serum peptide fractions from C18 reversed-phase chromatography possessed effectiveness of antifungal activity against three tested plant fungal including A. brassicicola, C. lunata and M. grisea with different MIC in the range 250-2,000 μg/ml from different peptide fraction. Moreover, Etotal (E1-E5 pooled together) from lysis solution extraction was found to able to inhibit three tested plant fungal at MIC 500 μg/ml. Moreover, B. cereus and E. faecium were the sensitive gram-positive bacteria with MIC in the range 250-4,000 μg/ml. However, all gram-negative bacteria were not affected by 4,000 μg/ml. Among these tested pathogens, plant fungal was quite sensitive to our peptide product. Etotal from lysis solution extraction will be the best candidate for using further in antifungal testing of other plant fungal both in vitro and in vivo. The further investigation and application will lead to possible use of latex serum as a great biotechnological resource to develop peptide –based product for the treatment of plant infection.

Abstract
The severity of environmental problems affecting air, soil, water, biodiversity, and forests, prompted relevant organizations to create mechanisms to prevent and manage these problems. One of these key mechanisms is Forest Certification, which is classified into two types, namely, Forest Management Certification (FM) and Chain of Custody Certification (CoC). The FM and CoC are certified by the relevant organization such as the Forest Stewardship Council (FSC) and the Programme for the Endorsement of Forest Certification (PEFC). These mechanisms will have an impact on the industry and commerce that use wood and tree products as a production base because of wood product importers may only import the certified products. This research project was designed to formulate policy recommendations for the potential development of rubber plantation owners and rubber wood consumers in Thailand to obtain international forest management certification. This was done using research data from two subprojects, namely, subproject 1: The analysis of rubber plantations on forest management certification status in Thailand, and subproject 2: Analysis of the factors affecting forest management certification of rubber plantations in Thailand. This resulted into four main policy recommendations in four broad areas: 1) Formulation of national policies and strategies to promote and access the forest certification systems for rubber plantation owners and rubber wood consumers; 2) Development of relevant organizations to promote and support forest certification in Thailand by determination and development of governmental organizations with the mission and potential in problem solving/negotiation and the potential developments of rubber plantation owners and rubber wood consumers for the whole system; 3) Development and availability of rubber plantation owners and rubber wood consumers in Thailand to obtain international certification; and 4) Research support in response to the development of forest certification in Thailand

Published: August 2019

Abstract
An innovative design of continuous latex gloves production lines was introduced in work. A modular approach to the designing process was described and key technologies were identified. Based on these technologies, industrial-sized prototypes were constructed and tested. The objectives were largely to reduce the production cost by some means such as reducing the thermal energy usage, shortening the length production line and time and decreasing the number of stationed workers. As a proof of concepts, prototypes of drying oven and stripping machine were constructed and the vulcanization experiments were carried out. The results were promising, for instances, the new drying oven with outside chain was projected to be able to reduce the thermal energy loss by approximately 12% compared to the traditional design and the stripping machine was shown to be able to vertically remove latex gloves from formers while occupying less space and potentially using fewer workers. From the vulcanization experiment, it was shown that the vulcanization time could be significantly shortened by pre-vulcanization and drying process.

Published: August 2019

Abstract
In this study, we used a game theoretic modelling technique to analyze the governmental policies by collecting natural rubber related data to create a model in order to select the policies that suit Thai rubber’s stakeholders. After the model has been created, we used sensitivity analysis to capture the uncertainties of parameters such as the success probabilities of the policies and the rubber price. The results from the game theoretic model show that there are two policies that should be selected by the government which is the policies that support the increase of natural rubber consumption by 10%-15%. However, in order for the government to optimally select these policies, the success rate of the policies needs to be at least 30%. Otherwise, none of the policies should be selected. Regarding the policy to support Tier-1 entrepreneurs, since the increase in demand by implementing this kind of policy is fairly small, the policy should not be chosen. The policy for Tier-2 companies owned by the local farmers should be supported when the chance of selling the products is more than 35%.

Abstract
To evaluate the suitability of three typical concrete material models, which are HJC material model, RHT material model and K&C material model respectively, in simulating concrete’s dynamic damage under air blast, a comparison between experiment observations and numerical simulation results is conducted. The three typical concrete material models are reviewed briefly at first. Then the experiment and numerical model information are presented. According to the comparison results, K&C material model shows the best suitability in simulating the damage mode of the concrete slab. RHT material model takes the second place for underestimating the concrete’s strength resistance. HJC material model, however, is no recommended for simulating concrete in such a situation.

Abstract
Graphene is a two-dimensional nanostructure filler with high thermal conductivity (5000 W/mK) and excellent mechanical properties, which has a very wide application prospect. Graphene is with super high specific surface area, which provides a greater contact area with polymer matrix. Then it is more easy to form the thermal conductive heat channels, which could improve the thermal conductivity of composite materials. The concentration, the ratio of geometrical diameters, the dispersion in the matrix and the interfacial bonding between graphene and the matrix materials will greatly affect the thermal conductivity of graphene reinforced composites. However, the graphene nanosheets can be easy to stack together and difficult to be dispersed into the solvent and polymer matrix. In order to improve the interfacial combination between graphene nanosheets and the matrix so as to reduce the interfacial thermal resistance of the composites, it is usually to modify the surface of graphene nanosheets, which mainly includes non-covalent modification and covalent modification. In this paper, researches on the thermal conductivity of graphene were reviewed, and the existing problems and the future research focus were also discussed.

Abstract
Under the influence of chloride-containing environment such like shallow sub-marine or littoral area, hot-dip Zn55Al coated steel sheet is easily corrode. Based on an applicable combination of parameters, a Cr(III)-based conversion coating(TCC) was formed on Zn55Al coating successfully based on Coldip 120 commercial passivator. The corrosion behaviour of the Cr(III) treated hot-dipped steel samples subjected to the Cr(III)-based passivation treatment was studied using electrochemical impedance spectroscopy (EIS) in a 3.5% NaCl solution, and the failure mechanism of the conversion coating-hot-dip coating system was investigated by analysing the time dependence of the electrochemical parameters of impedance. In addition, the role of corrosion products formed on Zn55Al during the different immersion time in the NaCl solution was also revealed by scanning electron morphology (SEM) and energy dispersive spectrometer (EDS).

Authors: Qie Longfei , Jing Shikai , Lian Ruichao , Wang Lei 
Published: August 2019

Abstract
Minimum length scale can fulfil the requirements for manufacturing and provide the extended robustness of design performance. This paper proposes a method to impose the minimum length scale in Heaviside-based morphological filters. With the method, the physical filter radius is first utilized to construct the element neighbourhood in density filter. Then, the density filter is embedded in the Heaviside filter and modified Heaviside filter. Finally, the morphological filters are constructed based on the principles of morphology-based restriction schemes, in which the Heaviside filter plays the role of dilation filter and the modified Heaviside filter acts as the erosion filter. Test results show that the minimum structural sizes in the final design are larger than the specified filter radius size. The characteristics of the basic filters and the embedded filters are discussed.

Authors: Peng Fuchang , Lai Qi , Chang Wei , Cui Yan 
Published: August 2019

Abstract
Mixed crystalline phase TiO2 nanoparticles with different content of Sm ion were prepared by a facile sol-gel method. The samples were characterized by XRD, XPS, UV-Vis-DRS, and PL. The influence of Sm-doping on structure and visible light photocatalytic activity of mixed phase TiO2 was evaluated by photocatalytic degradation of MB under the irradiation of fluorescent lamp. The results indicate that samarium appears two kinds of Sm3+ and Sm2+ valence state on the surface of TiO2. Sm doping can restrain the phase transition from anatase to rutile, and prevent the grain growth. Appropriate amount of Sm doping and the proportions of rutile and anatase mixed phase can effectively inhibit the recombination of photo-generated electron and hole pairs, expand the wavelength range of absorption spectrum. Moreover, the photocatalytic activity of Sm-TiO2 in MB degradation is evidently enhanced. The MB degradation rate of Sm-TiO2 samples with n(Sm): n(Ti)=0.006 is the best under the irradiation of fluorescent light when the sintered temperature T=500°C, it is 97% within 6 h, which is significantly higher than 56.4% of pure TiO2 under the same experimental conditions.

Published: August 2019

Abstract
The coupling of cavity noise and the structural vibration caused by the flow around the cavity at high speed will adversely affect the structure of the aircraft and threaten flight safety. Through the synchronous test method of noise and structural response, the test of acoustic/vibration coupling characteristics of the elastic cavity at supersonic condition in a wind tunnel was carried out, and the elastic cavity noise, structural vibration response characteristics and the coupling law were studied. The results show that the intracavity noise load mainly affects the low-order modal response of the cavity structure. Compared with the rigid cavity, the maximum position of the intracavity noise affected by the radiated sound wave is near the elastic boundary with strong vibration characteristics, and the noise peak frequency component is particularly affected.

Authors: Long Peiheng , Shi Wenhao , Hou Suwei , Jiao Chiyu , Xu Haomai 
Published: August 2019

Abstract
The anchorage characteristics of CFRP plate anchors are controlled by anchorage deformation. The anchoring efficiency of anchors under tension and the force mechanism of CFRP plates are studied. The preliminary design of splint anchors is carried out by ANSYS general software. The deformation and stress of the CFRP plate under the displacement control of the different splint edges are analyzed, and the corresponding splint displacement is 0.55mm when the anchoring efficiency is 100%. At the same time, the finite element analysis results were compared by the anchor static test, and the stress loss and relative slip of the CFRP plate were analyzed. The research shows that: from the test results, when the total displacement of the splint reaches 0.55mm, the CFRP plate undergoes longitudinal splitting failure; when the total displacement of the splint reaches 0.50mm, the test anchoring performance is the best, the anchoring efficiency is 82%; the total displacement of the splint is 0.30∼0.55. When mm is used, the slip amount of CFRP plate is 0.69∼3.31mm. The better the anchoring performance is, the smaller the slip amount is. The loss of stress caused by CFRP plate retraction and anchorage deformation is recommended to be 7.5% of the total tensile stress.

Abstract
Commercially available polypropylene fiber (PPF) samples with relaxation heat setting for 30 minutes in a drying oven at various temperatures (room temperature, 90 °C, 100 °C, 110 °C, 120 °C, 130 °C, 140 °C, 150 °C, respectively.) were prepared for measurement of their sonic velocity, orientation degree, orientation angle and modulus. According to the obtained data for the PPF molecular orientation before and after the relaxation heat setting, it is found that, with the increasing of relaxation heat setting temperature, the sonic velocity in PPF, orientation degree and modulus decreased, while the orientation angle increased. The result may be helpful to choose proper working temperature for PP hernia patch fabrication.
