"The temperature and humidity inside poultry houses are highly coupled through nonlinear psychrometric processes, and the limitation of actuators makes this type of system difficult to control. To understand the dynamics of such systems and further to design a suitable controller, in this study, the mathematical model for a closed poultry house was derived from the governing equations of the various components related to the poultry house, including the energy and mass balance and the psychrometric correlations of the moist air. The model was simulated and the simulation result was compared to the data collected experimentally for model verification and control gains estimation. Under the assumptions of 70 percent Active Mixing Volume (AMV) with the constant maximum ventilation rate in the case study, the temperature and the relative humidity simulated results were in the good agreement with the real physical plant data. At the front, the middle and the rear part ofthe poultry house, the root-mean-square error (RMSE) obtained for internal temperatures are 1.17oC, 0.68oC, and 0.46oC, respectively. Andthose data for relative humidity are 4.31%, 8.07%, and 53.54%, respectively."

"The cloud is an outstandingplatform to deal with functionally equivalent services which are exponentiallyincreasing day-by-day. The selection of servicesto meet the client requirements is a subtle task. The services can be selected byranking all the candidate services using their network and non-network Quality-of-Service (QoS) parameters, which is formulated as a NP hard optimization problem. In this paper, weproposed a linear discriminant analysis (LDA) based a four level matching model for service selection based on QoS parameters,which includes description matching of a service, matchmaking phase, LDA-based QoS matching and ranking. The LDA-serviceselection agent is deployed on each cloud to classify services into classes andrank the services based on the aggregate QoS value of each service. Finally,the test results show the efficiency in service selection with minimaldiscovery overhead, significant reduction in the computation time and thenumber of candidate services to be considered."

"End-of-life Vehicle(ELV) recovery is a promising strategy to minimize the environmental impact ofautomotives on environmental sustainability. This study aims to assess thecommunity?s knowledge from a socio-technical perspective on ELV. A survey wasconducted in Japan and Malaysia to assess public perception on ELV recovery.The results showed that the communities in both countries have basic knowledgeand a reasonably good level of awareness on environmental issues and recoverystrategies such as recycling. However, there is a high level of uncertainty onthe concept of ELV reuse and remanufacturing, as more than 50% of respondentswere unsure of their willingness to participate in ELV initiatives. Therespondents agreed that the industry and government should take the necessarysteps to support the reuse strategy. The paper concludes with suggestions froma socio-technical perspective, which aim to ensure an effective implementationof ELV recovery through reuse and remanufacturing."

"We conducted a finite element simulation by using a computer program, ATENA, to verifythe behavior of T-section reinforced concrete beams strengthened by bonded wireropes in the negative moment region with a pretensioned initial prestressing force; we compared thisbehavior with that in experimental tests. The simulation was performed on five models consistingof one unstrengthened beam and beams strengthened by wire ropes with initial prestressing forces of 0%, 10%, 20%,and 30%. We found that the capacity of a flexuralload had the ratios to the experimental results close to 1 ? that is, 1.25, 1.16, 1.12, 1.01, and 1.10, for UB, SB1, SB2,SB3, and SB4, respectively. The ratios of effective stiffness, as the result ofthe simulation, to the experimental results were 1.45, 1.08, 1.76, 2.13, and2.46 for UB, SB1, SB2, SB3, and SB4, respectively. We also observed that crack propagation developedin the finite element simulation indicated that all modelsunderwent flexural failure."

"As an initial analysis,numerical simulation has more advantages in saving time and costs regarding experiments. For example, variations in flowconditions and geometry can be adjusted easily to obtain results. Computationalfluid dynamics (CFD) methods, suchas the k-ε model, renormalizationgroup (RNG) k-ε model and reynolds stress model (RSM), are widely used toconduct research on differentobjects and conditions. Choosing the appropriate model helps produce and developconstant values.Modeling studies as appropriate, i.e., in the turbulent flow simulation in the windtunnel, isdone to get a more accurate result. This study was conducted by comparing the results ofthe simulation k-ε model, RNG k-ε model and RSM, which is validated by the testresults. The air had adensity of 1,205 kg/m3, a viscosity of 4×10-5 m2/sand a normal speed of 6 m/s. By comparing the simulation results of the k-ε model, RNG k-ε model and RSM, which isvalidated by the test results, the third turbulencemodel provided good results to predict the distribution of speedand pressure of the fluid flow in the wind tunnel. As for predicting theturbulent kinetic energy, turbulent dissipation rate and turbulent effectiveviscosity, the k-εmodel was effectivelyused with comparable results to the RSM models."

"Nanostructured zincoxide (ZnO) was synthesized via a sonochemical method. The effect of the duration of ultrasonic irradiation in a continuous mode on the generated particles was investigated. Additionally, the effect of flowing either air or nitrogen during the sonication process was investigated. Zinc nitrate andammonia water-based solutions were selected as chemicals without the additionof other surfactants. The generated particles indicated that a wurtzitestructure of ZnO in a hexagonal phase was formed with a crystalline size that increasedas the ultrasound irradiation time increased. The morphology of the generatedZnO particles could be changed from flowerlike to needlelike structures viacontinuous ultrasound irradiation over one to two hours, resulting in increasesin the particle lengths and decreases in the particle diameters from 200 to 80nm. Photoluminescence intensity was also increased with increases in the ultrasonicirradiation times. Photoluminescence spectra were also influenced by theatmospheric environment. Two bands centered at 390 and 500 nm were generatedunder a nitrogen environment. On the other hand, a single wide band with a peakat around 430 nm was found for particles generated under an air environment. Itcan be applied for light emitting diodes (LED) or laser fabrication with acontrolled emitting band."

"A multi modelpredictive control and proportional-integral controller switching (MMPCPIS)approach is proposed to control a nonlinear distillation column. The study wasimplemented on a multivariable nonlinear distillation column (Column A). Thesetpoint tracking and disturbance rejection performances of the proposedMMPCPIS were evaluated and compared to a proportional-integral(PI) controller and the hybrid controller (HC). MMPCPIS developed to overcome theHC?s limitation when dealing with very large disturbance changes (50%). MMPCPIS provided improvements by 27% and 31%of the ISE (integral of square error) for feed flow rate andfeed composition disturbance changes, respectively, comparedwith the PI controller, and 24% and 54% of the ISE for feed flow rate and feedcomposition disturbancechange, respectively, compared with HC."

"A mechanical assembly consists of several components to perform an intended function. At the design stage, the intended function must be converted into critical product dimensions. After determining the dimensions, a designer must determine the assembly tolerance and allocate this tolerance to the tolerances of the corresponding components. After determining the optimal tolerances, process selection must be conducted along with production allocation to the selected process. There are three aspects in commercial competition that must be considered by a manufacturing company: cost, quality, and delivery. The aim of this research is to develop an optimization model for process selection for a make to order company to minimize manufacturing cost, quality loss, and lateness cost. The model attempts to determine optimal tolerance and production allocation, which takes into consideration the production capacity and process sequence. Hence, the model attempts to include not only the product design decision, but also to solve the process selection and allocation problems. A numerical example is provided to show the implementation of the model."
