This paper presents a new algorithm for Finite Capacity MRP (FCMRP) in a multi-stage flexible flow shop. The proposed algorithm consists of four conventional metaheuristics namely, Genetic Algorithm (GA), Tabu Search (TS), Variable Neighborhood Search (VNS), and Simulated Annealing (SA) hybridized with Linear Programming (LP). The objective is to minimize the total cost, which is the sum of tardiness, earliness, and flow-time costs. There are two main steps of the proposed algorithm. Firstly, an efficient sequence of orders is generated by the proposed metaheuristics in a way that reduce the total cost. In this step, the required operations of the orders are scheduled based on two scheduling options called permutation and non-permutation. Secondly, the total cost is minimized by the LP model. The required parameters of the metaheuristics are tuned by using real data from automotive companies. The result shows that the proposed algorithm significantly outperforms the existing algorithm, and GA obtains the best total cost.

In this present research, rice husk was modified using a cationic surfactant cetyltrimethylammonium bromide (CTAB) and used as an adsorbent (MRH) to remove methyl orange dye (MO, anionic dye) from aqueous solution. A series of experiments were carried out in a batch process to determine the influences of different parameters such as pH, contact time, initial concentration of adsorbate and adsorbent dose. The kinetic data obtained from different batch experiments were analyzed employing pseudo-first-order, pseudo-second-order, Elovich and intra-particle diffusion model equations. The equilibrium adsorption data were analyzed by Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) isotherm models. The results show that pseudo-secondorder kinetic model and Freundlich adsorption isotherm model achieved better fit with the experimental data. The percent adsorption and equilibrium adsorption capacity (qe) were increased with the increasing amount of adsorbent and initial concentration of dye, respectively. Thermodynamic parameters such as Gibbs free energy change (∆G), enthalpy change (∆H) and entropy change (∆S) were calculated and the results showed that the adsorption was spontaneous and exothermic.

An on-line corrosion monitor based on the principle of produced hydrogen effusion through a pipe wall due to the flow accelerated corrosion has been designed in an operating cycle mode which is complex. Using AISI 1045 and AISI 304 steels as material of probe equipped with this monitor expects to reduce the complexity of this system, the continuous mode. Type, characteristic and thickness of oxides formed on both steel surfaces affect the measurement of the rate of hydrogen production from the corrosion inside the pipe. Formation of oxides on AISI 1045 and AISI 304 at 673 K for 168 and 720 h in air was studied to determine type and thickness of oxides formed on steel surfaces under different exposure times. Oxidation of steels was performed in the heated air inside the furnace. The oxide formed on AISI 1045 surface was magnetite with different sizes of oxide particles because of the different exposure times. The oxide formed on AISI 304 surface was found as iron oxide and chromium oxide for 720 h. The thicknesses of oxides formed on AISI 1045 were 2.92 μm and 6.22 μm for 168 and 720 h, respectively. While the thicknesses of oxides formed on AISI 304 were not determined due to the irregular characteristic of oxide formed. Type and thickness of oxides obtained from this research could be used to predict the hydrogen pressure inside AISI 1045 and AISI 304 probes.

The extracts of Limnophila aromatica was conducted using 5 temperatures and 6 extraction times and the obtained color, pH, flavor profile and the contents of 5´ribonucleotides were compared. Extraction at higher temperature and longer time resulted in decrease of L* and a* values, but increase of b* value. The pH values of extracts had significantly decreased with longer time of extraction. Nine flavor terms and their intensities were identified. There was no ribonucleotides detected in the distilled water extracts. In contrast, when using methanol as the solvent for the extraction of dried samples, the 5´AMP and 5´UMP were detected.

The effect of Metakaolinization on the thermal and physiochemical propperties of Kankara kaolin is presented. Thermogravimetric Analysis (TGA) and Differential Thermogravimetric (DTG) scan of Kankara kaolin indicated that kaolin was transformed to metakaolin at temperature above 600°C. The TGA/DTG scan of the metakaolin produced showed that the material was thermally stable at temperature range of 600–900°C. The metakaolin was characterized using X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and BrunauerEmmett-Teller (BET) texture analysis. The metakaolin formed was amorphous, having average particle size of 2.5 μm. The specific surface area values of the raw kaolin and the metakaolin formed were 12.95 and 19.38 m/g respectively. The pore volume values of the raw kaolin and the metakaolin were 0.0038 and 0.0585 cm/g respectively.

The aim of this research is the product design review in a virtual reality environment. The design activities consist of the usage or not of the haptic arm force-feedback combined or not with 3D stereoscopic display through basic sensors. The movements of design activities were evaluated by the low basic sensors application consisting of docking, duration, and instability sensor. The use case was thus organized around a barrel cam mechanism design which it has a single rotation motion but a complex cam 3D trajectory. We are specifically concerned by activities involved at design stage or at manufacturing preparation stage and we will have tuning design parameters to ensure that the mechanism is working well. We have implemented the experiment on four environments including either stereoscopy or haptic force-feedback device were used to establish comparisons respect to this research.

The aim of this research was to find the suitable conditions for bio-ethanol production from Ceratophyllum demersum L., an abundant aquatic plant. The parameters affected to alcohol production were evaluated. Percentage of solid (10, 20, and 30% (w/v)), the amount of yeast (5, 10, and 15% (w/v)), pH value (4, 5, and 6) and temperature (30, 35, and 40°C) were carried out. The results elucidated that the conditions to produce the maximum bio-ethanol from Ceratophyllum demersum L. was applied with 10% (w/v) of solid, 10% (w/v) of yeast, controlled pH value of 6 and temperature of 30°C. The highest yield of bio-ethanol production was reached 2.92 g ethanol/L within 24 h. Moreover, the Carbon Footprint for ethanol production was calculated only from 2 steps of life cycle analysis which were the step of raw material acquisition from macro algae cultivation and manufacturing process from bio-ethanol production. Consequently, the carbon footprint for ethanol production from Ceratophyllum demersum L. was 77.88 kg CO 2 equivalent.
本研究的目的是寻找以丰富的水生植物角藻为原料生产生物乙醇的适宜条件。评价了工艺参数对酒精生产的影响。测定了固含量(10、20和30% (w/v))、酵母用量(5、10和15% (w/v))、pH值(4、5和6)和温度(30、35和40℃)。结果表明，在固体添加量10% (w/v)、酵母添加量10% (w/v)、pH控制在6、温度控制在30℃的条件下，毛霉产乙醇量最大。生物乙醇的最高产率在24 h内达到2.92 g乙醇/L。并且，乙醇生产的碳足迹仅通过生命周期分析的两个步骤来计算，即从大型藻类培养中获取原料和从生物乙醇生产中制造过程。因此，绿藻生产乙醇的碳足迹为77.88 kg CO 2当量。

Healthcare improvement is complicated and has become public concern in Thailand during the past decade. The purpose of this research project is to improve the quality of healthcare and patient satisfaction utilizing Lean principles. This research is conducted in a middle-sized Pluakdaeng hospital in Rayong, Thailand where there are approximately 364 patients daily under the supervision of 6 doctors, 6 pharmacists, 53 nurses and 124 supportive staffs. In Lean studies, computer simulation and Value Stream Mapping (VSM) are utilized to define and eliminate wastes in the hospital business process. Findings indicate that service rate at the hospital can be increased to 28.98% and the average patient waiting time can be reduced to 28.65%. Future work, improvements, limitations and suggestions on the current research are also provided and discussed.
