title: Simulation-based Policy Making for Autonomous Decentralized Energy Systems-Rice husk use in Thailand-

description: This paper introduces the simulation-based policy-making methodology for autonomous decentralized decision-making systems and shows its effectiveness by taking renewable energy (rice husk) use in Thailand as an example.  The stakeholders, e.g., energy consumers, energy suppliers, retailers and national/local governments included in the renewable energy systems, are considered to be the autonomous decentralized decision-makers. However, the criteria and constraints of the stakeholders' decision-making are usually unknown to policy makers/planners, and even the level of autonomy, that is, the capacity of decision-makers, may be included in the design targets of education and policy.  This study has developed the simulation model for designing the autonomous decision-making systems including the stakeholders of the market with a variety of transaction rules. First, the simulation-based policy-making approach is introduced.  Second, the decision rules of the stakeholders in the market of rice husk in Thailand were collected and analyzed based on the results of the interviews and the questionnaire survey for developing the behavioral  model.  And finally, several simple sets of policy rules for the energy market are examined by using the simulation model for demonstrating the effectiveness of the simulation-based policy-making approach.

title: INFLUENCE OF MOMENT GRADIENT ON ROTATION CAPACITY OF STEEL FLEXURAL MEMBERS

description: Current seismic design procedures implicitly permit the inelastic structural deformations under strong ground motions for economic reasons. The local ductility is used as a parameter for evaluating the available inelastic performances of structures. Current code provisions take into account the ductility at the level of section, but it is necessary to study member ductility. One of the main factors influencing the value of ductility is moment gradient. This research presents a new method to determine ductility for constant-moment loading of flexural members based on theoretical and numerical studies. A numerical study was carried out on welded I-beams under a monotonic static loading, using nonlinear buckling analysis considering local and overall instabilities. The results illustrate that this new method is more accurate than others, can be used to predict ductility for constant-moment loading, and may be employed for different gradients of moments.

title: Modeling of continuous operation esterification of fatty acid catalyzed by Amberlyst15 in the presence of molecular sieve

description: The esterification is reaction that can convert fatty acid from vegetable oil to biodiesel. This is alternative biodiesel production in case of feedstock contains high free fatty acid (FFA) content. In this study, the model of continuous esterification in the presence of solid acid catalyst was developed and simulated at different methanol/FFA molar ratios and reactant flow rates. Importantly, the effect of molecular sieve adding on FFA conversion and product yield were determined. The results demonstrate that conversion of FFA can reach to 99% when molecular sieve along with catalyst were added due to the water adsorbed by molecular sieve, resulting the equilibrium of the esterification reaction more shifted to biodiesel.

title: Simulation of a Solar Absorption Chiller and a PV-driven Electric Chiller

description: Popularity of solar cooling techniques is increasing due to its environmental friendliness and its use of renewable energy, leading to reduction in capital investment cost. In this study, hourly simulation will be done on a model of small solar powered 4.7kWth absorption chiller, and a model of PV-driven 7.1kWth electrical chiller. For absorption chiller, 2 scenarios will be considered, one where the hot water is left in collectors to cool down during OFF hours, and another where hot water from the collectors will be drained back to store the thermal energy. Furthermore lifecycle costs were calculated for economic comparison of the systems. Simulation results show that the modeled systems are able to provide cooling, and the lifecycle costing shows, that for small size systems, grid operated chiller is more economically feasible than a solar powered absorption chiller and PV-driven electric chiller.

title: FATIGUE TEST OF STEEL GIRDER WEB PENETRATION DETAILS WITH A SLIT

description: Fatigue cracking in steel girder web penetration details is so dangerous that it can break steel girders. A one-meter-long crack was detected in Yamazoe Bridge in 2006. Since a number of highway bridges with such web penetration details may exist in Japan, it is of urgent importance to understand these fatigue-strength properties. However, few fatigue tests have been reported on steel girder web penetration details. The purpose of this study is to clarify fatigue behavior of steel girder web penetration details with a slit through fatigue tests of specimens with these details. We designed and fabricated girder specimens that have steel girder web penetration details, in which cross-beam bottom flanges are connected to each top or bottom surface of a slit by welding. First, we conducted static loading tests to understand the stress distributions around web penetration details. Second, we conducted fatigue tests to examine fatigue crack initiation and propagation behavior and fatigue strength.

title: Characterization of lignin extracted from eucalyptus wood chip by organosolv and subsequent alkaline precipitation processes

description: The present work studied the characteristics of lignin extracted from eucalyptus wood chip by organosolv (as called organosolv lignin; OL), and organosolv subsequent alkaline precipitation (as called organosolv lignin subsequent alkaline precipitation; OLA). It is noted that lignin from soda process (as called soda lignin; SL) was also characterized for comparison. In detail, OL was fractionated using ternary mixture of methyl isobutyl ketone (MIBK): methanol: water in the presence with 0.008 M of H2SO4 acid promoters at 180?C for 60 min. Then, it was characterized by Klason lignin, elemental analysis, thermal gravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), and Fourier transform-Infrared spectroscopy (FT-IR) to determinate the physico-chemical properties and structural features. When compared with OLA, the result of FT-IR proved the OL structure not changed when OL was treated with alkaline precipitation. Moreover; organosolv subsequent alkaline precipitation could remove the contaminations content of OL (i.e. sugar, sulfur, MIBK) due to their association between lignin and contaminations.

title: Effectiveness of transesterification catalysts on biodiesel production from 11 types of oils

description: Transesterification from 11 types of oils (soybean, palm, rice bran, Sunflower, corn, Camellia Oleifera, olive, Canola flower, sesame, animal and kitchen used oil) were studied. Biodiesel production by using NaOH, KOH, H2SO4, HCL and Sodium methoxide as catalysts were carried out. The reaction mechanism was proposed and the separate effects of reaction temperature, molar ratio of methanol to oil, mass ratio of catalyst to oil and repeated experiments were investigated. The results showed that the yield of biodiesel production by Sodium methoxide catalyst was accessed in Canola flower oil and had percentage of yield more than others. The test results of heating value of Canola flower oil biodiesel was 48,043 kJ/kg, pH 5-7 and viscosity 0.7-4 Centistokes. The results proved that transesterification of Canola flower oil to biodiesel using Sodium methoxide as a catalyst is a commercially viable way to decrease the costs of biodiesel production.

title: Combustion properties of Thai biomass

description: The design and operation of biomass combustion systems rely substantially on several biomass characteristics, namely, heating value, moisture, ash content, density and elemental composition. This worked provides information on heating values, proximate analysis ultimate analysis, ash deposition and thermal behavior of biomass. Heating values of biomass vary between 13-22 MJ/kg (dry basis). Biomass has high volatile matter (60-90%) and low fixed carbon compare with fossil fuel. High oxygen concentration was found in biomass (40-50% d.a.f.). Mineral matter deposition in biomass created slagging, fouling and high temperature corrosion in boiler. Each type of biomass has individual characteristic and required specific suitable operation condition setting for efficiency energy utilization.

title: Performance prediction of a downdraft gasifier using equilibrium model: effect of different biomass

description: In this paper, a thermochemical equilibrium model was used to simulate the gasification process of biomass and predict the composition of the producer gas. The predicted results agreed well with those of the experiments available in the literature. The model was then employed in order to optimize the selection procedure of a specific biomass for a certain application. For this purpose, at constant operational conditions, the ultimate compositions of various biomasses were used to investigate the influence on syngas characteristics. These included the calorific value, gasification efficiencies and the volume of producer gas.

title: The utilization and sustainability of jatropha oil biodiesel in the agricultural sector of Myanmar

description: In Myanmar, Jatropha trees grow naturally and abundantly. But currently there are only a few commercial farms just in starting. Agriculture is backbone of Myanmar economy and it contributes 36.4% of GDP in 2011/2012 and over 70% of population work in it. In agriculture sector most of the machineries used are driven by diesel engines. Considering green and renewable energy, biodiesel is one of the best alternative fuels for diesel engines. Basically biodiesel can be processed from vegetable oils by the transesterification by using alcohol and catalyst. From our research on Jatropha oil, we processed methyl ester type Jatropha oil biodiesel namely Jatropha oil methyl ester (JME) and analyzed the fuel properties. The five stages speed-load engine experiments were carried out with a single cylinder DI diesel engine by fuelling with JME and, rapeseed oil methyl ester (RME), soybean oil methyl ester (SME) and diesel fuel (JIS No. 2) were used for comparison. From the analytical and experimental results, we found that JME has good fuel properties, fair ignition ability, less exhaust emissions and good thermal efficiencies. Base on these findings, our main purpose of this study is to get the interest and on the development of Jatropha plantation and to point out the potential of Jatropha oil biodiesel utilization and sustainability to the government, public and private sectors of Myanmar.

title: Ecological, technological and economic advantages of co-digestion for biogas production

description: Co-digestion is the simultaneous digestion of mixture of two or more substrates and a promising opportunity for the utilization of agricultural residues. Studies demonstrated that digestion of a variety of substrates, especially the utilization of animal manure together with solid agricultural residues and/or energy crops improves the nutrient balance and the anaerobic digestion process is more stable. Further advantages are an optimized use of fermenter volume which will result in increased plant capacities and the equalization of solid matter distribution in the fermenter. Using Agricultural waste as energy source is an effective solution for waste management and can reduce environmental problems as well as global warming [6]. The utilization of agricultural residues as source for biogas production will furthermore contribute to economic, environmental and social sustainability.

title: Photocatalytic hydrogen generation from water with metal loaded strontium titanate nanofibers

description: Hydrogen production rate via photocatalytic water-splitting of strontium titanate nanofibers was improved via silver and cobalt loading. The loading of the metal salts was achieved via photodeposition and co-electrospinning. The metal loaded photocatalysts were characterized via field-emission scanning electron microscopy with energy dispersive spectroscopy (FE-SEM/EDS), X-ray diffraction (XRD) analysis, UV-visible spectroscopy, and photo-electron yield spectroscopy.  Hydrogen production rates were found to be improved up to as high as 2.5 mmol h-1 g-1 for Co2+ loading and as high as 1.8 mmol h-1 g-1 for Ag+ loading. The improvement photocatalytic rates were majorly attributed to the change in electronical properties of SrTiO3 with the loading of the metals.

title: Reducing cooling requirement by using cladding for external walls ventilated at rear

description: The choice of building components can significantly influence the energy performance of buildings. In cold climates building components determine the dimensions of transmission and ventilation heat loss and are crucial to thermal comfort. On the other hand, the amount of solar heat gain in hot climates depends on the building components as well. Transparent components have a higher influence and play a more important role for heating up buildings than nontransparent (opaque) components do. Therefore more research has been conducted on transparent building components until now. Research on claddings has been neglected, even though it could prove to have a substantial influence on energy savings with respect to cooling. Claddings for external walls ventilated at rear (opaque) are characterized in their thermal behavior primarily by the properties of thermal insulation material and the micro-climatic conditions in the air layer. In summer situations, the temperature differences between surface temperature, exterior and interior and also the air gap temperature cause stack-effects. Therefore, a higher air mass flow for the air gap is expected. As a result, it can be supposed that the heat from the exterior layered cladding is reduced by heat transportation of the airflow. This paper deals with experimental studies to investigate and calculate the volumetric air flow of claddings for external walls ventilated at rear and their influence on reducing the cooling requirement. For this purpose, different cladding surfaces have been investigated.

title: Household energy consumption perspectives for MECON group in Laos

description: Household energy consumption of New Modern Energy CONsumbers (MECON) group in Lao PDR is presented in this paper. MECON group is group of people earning between 60-150 USD per month and electrified household with monthly electricity bill less than 7 USD. The forecasted household energy consumption is very important in Laos because household sector represents the highest energy consumption comparing to other sectors. Therefore, energy consumption in household for MECON group is considered for case study for energy policy and planning for household sector because it is the second largest share after the low income group. LEAP is used as tool to simulate the energy consumption in MECON group in LAOS for up to the year 2030.

title: New modern energy consumers: a survey on energy consumption and energy efficiency of Cambodian households

description: A survey on socio-economic perspectives of Cambodian households related to energy efficiency and consumption was conducted in 2014. We focused on information about households, their current energy, and energy efficiency. A total of 503 electrified households living on an income between two and five dollars, defined as MECCON households, from six provinces and the capital city of Cambodia were selected for this study. A statistical analysis was done using MS-Excel. The study interestingly shows that among the chief wage earners, 13% have a university degree while 12% are government officials. Approximately 94% of the MECON households have access to electricity through the national and community grids. Aside from electricity, other sources such as LPG, charcoal, and biomass are commonly used. For lighting, it is seen that 29% of the studied households use incandescent, while 83.8% employ fluorescent lamp, 54.5% have compact incandescent lamp installed, and only 5.3% consider LED lamp. Finally, it is found that 35% of the MECON households intend to own a refrigerator, 13% are willing to have a washing machine, while about 52% wish to have irons, air conditioners, and so on equipped in their home. In terms of energy efficiency, limited knowledge on it is seen among the studied households. This requires a special attention from the government to widely promote energy efficiency awareness and to establish a strong policy that will contribute to economic development, energy efficiency and security, as well as environmental benefits of the country.
