The purpose of this study was to investigate and describe farmers’ cognitive perception and adaptation patterns to deal with climate change that include risk perception, perceived adaptive capacity, and perceived outcomes. The study applied the grounded theory methodology to understand learning processes and conditions which determined the risk perception, perceived adaptive capacity, and perceived outcomes. Data was obtained from in-depth interviews with 20 rice farmers who have been affected from drought in non-irrigating area of Nongphra, Pichit. The study identified various perception and adaptation patterns of the farmers, i.e., coping, recurring, incremental, and transformative. These patterns could understand by various cognitive conditions determining adaptation trajectories, namely, sense of security, fear of taking risks, exposure to climate information, and persistent tendency. Therefore, some policy implications to promote farmers' cognition to adaptation were to build risk awareness by communicating extensive risk information. Another suggestion was to build farmers’ resistance to impacts by providing farmers with knowledge and adaptive practices that were suitable to a local context, ensuring beneficial outcomes for adaptation.

This paper proposes the method, called the Filter Partitioning Machine Learning Classifier (FPMLC). It can enhance an accuracy of indoor positioning based on fingerprinting by using machine learning algorithms and prominent access points (APs). FPMLC selects limited information of groups of the signal strength and combines a clustering task and a classification task. There are three processes in FPMLC, i.e. feature selection to choose prominent APs, clustering to determine approximated positions, and classification to determine fine positions. This work demonstrates the procedure of FPMLC creation. The results of FPMLC are compared with those of a primitive method by using real measured data. FPMLC is compared with well-known machine learning classifiers, i.e. Decision Tree, Naive Bayes, and Artificial Neural Networks. The performance comparison is done in terms of accuracy and error distance between classified positions and actual positions. The appropriate number of selected prominent APs and the number of clusters, are assigned in the clustering process. The result of this study shows that FPMLC can increase performance for indoor positioning of all classifiers. In addition, FPMLC is the most optimized model while having Decision Tree as its classifier.

The assessment of sustainability performance has become a topic widely discussed by business practitioners. The complexity of this issue is highlighted by the incorporation of a large number of criteria. Several methods under the context of Multiple Criteria Decision Analysis (MCDA) have been employed to facilitate the aggregation of various criteria and to provide a guideline for decision making. As most MCDA methods assume that each criterion plays a role equal to its weight, this paper investigates the weight of each criterion in evaluation of corporate sustainability by focusing on the sugar industry in order to respond to the lack of MCDA and sustainability studies in this sector. The weighting is analysed by means of the relative importance based upon interviews and the direct rating technique. Statistical analysis is also conducted. The results from this empirical research indicate priorities of sustainability criteria and demonstrate the diversity of concerns within the industry when deciding on sustainability policies and strategies. This encourages practitioners to incorporate uncertain weights of sustainability criteria into decision making. Possible reasons for variations or changes in weights have been also discussed, and this enables practitioners to perform a sensitivity analysis in a more realistic way.

This paper addresses a problem of the two-stage flexible flow shop with reentrant and blocking constraints in Hard Disk Drive Manufacturing. This problem can be formulated as a deterministic FFS|stage=2,rcrc, block|Cmax problem. In this study, adaptive Hybrid Particle Swarm Optimization with Cauchy distribution (HPSO) was developed to solve the problem. The objective of this research is to find the sequences in order to minimize the makespan. To show their performances, computational experiments were performed on a number of test problems and the results are reported. Experimental results show that the proposed algorithms give better solutions than the classical Particle Swarm Optimization (PSO) for all test problems. Additionally, the relative improvement (RI) of the makespan solutions obtained by the proposed algorithms with respect to those of the current practice is performed in order to measure the quality of the makespan solutions generated by the proposed algorithms. The RI results show that the HPSO algorithm can improve the makespan solution by averages of 14.78%.

Soil salinity causes corrosion of engineering structures worldwide. The main cause of soil salinization is capillary rise of saline groundwater. Soil salinity can be mitigated once the capillary rise of saline groundwater in soils is understood. The objective of this paper is to present experimental results of capillary rising rates of different salt concentration waters in three sandy soils. Each sample comprised of a soil column 300-mm height and 50-mm in diameter steeped in a 25-mm deep saline water pool for a time period to allow for the capillary action to develop. The salinity strength varied from fresh water, EC = 2 dS/m, to medium saline (50, 100, and 150 dS/m), and to high saline water (200 dS/m). It was found that the highest rate of capillary rise occurred in medium saline waters, while the lowest is the fresh water. The very saline water has lower rate than the medium ones but higher than fresh water.

In manufacturing process where efficiency is crucial in order to remain competitive, flowshop is a common configuration in which machines are arranged in series and products are produced through the stages one by one. In certain production processes, the machines are frequently configured in the way that each production stage may contain multiple processing units in parallel or hybrid. Moreover, along with precedent conditions, the sequence dependent setup times may exist. Finally, in case there is no buffer, a machine is said to be blocked if the next stage to handle its output is being occupied. Such NP-Hard problem, referred as Blocking Hybrid Flowshop Scheduling Problem with Sequence Dependent Setup/Changeover Times, is usually not possible to find the best exact solution to satisfy optimization objectives such as minimization of the overall production time. Thus, it is usually solved by approximate algorithms such as metaheuristics. In this paper, we investigate comparatively the effectiveness of the two approaches: a Genetic Algorithm (GA) and an Artificial Bee Colony (ABC) algorithm. GA is inspired by the process of natural selection. ABC, in the same manner, resembles the way types of bees perform specific functions and work collectively to find their foods by means of division of labor. Additionally, we apply an algorithm to improve the GA and ABC algorithms so that they can take advantage of parallel processing resources of modern multiple core processors while eliminate the need for screening the optimal parameters of both algorithms in advance.

In this paper, we survey the role of mathematics in electrical network connections. We discuss the behavior of current flows, voltages and impedances mainly for series-parallel networks. In both one-port and multiport electrical networks, the currents through these networks are governed by Maxwell’s power principle. The joint impedances of the networks, given in terms of series sum and parallel sum, satisfy the series-parallel inequality. An abstract idea can be formulated in functional analysis aspect in which any network connection is viewed to be a binary operation for positive operators satisfying certain algebraic, order and topological properties.

In this paper, the influence of fly ash fineness on water requirement and shrinkage of blended cement mortar was studied. The results indicate that the water requirement and shrinkage characteristic of the blended cement mortar are dependent on fly ash fineness and replacement level. The use of coarse fly ash slightly reduces the water requirement but greatly reduced the drying and the autogenous shrinkage of the blended cement mortars and the reduction is more with an increase in the fly ash replacement level. The finer fly ashes further reduce the water requirement, but increase the drying and the autogenous shrinkages as compared with coarser fly ash. The incorporation of superplasticizer drastically reduces the water requirement, but the effect on the drying and autogenous shrinkages of the normal Portland cement mortar is small. However, for the fly ash mortar, the use of superplasticizer results in a decrease in drying shrinkage and in a substantial increase in the autogenous shrinkage particularly for the fine fly ash at a high replacement level.

Because of nonlinear strain distributions caused either by abrupt changes in geometry or in loading in deep beam, the approach for conventional beams is not applicable. Consequently, strut-and-tie model (STM) has been applied as the most rational and simple method for strength prediction and design of reinforced concrete deep beams. A deep beam is idealized by the STM as a truss-like structure consisting of diagonal concrete struts and tension ties. There have been numerous works proposing the STMs for deep beams. However, uncertainty and complexity in shear strength computations of deep beams can be found in some STMs. Therefore, improvement of methods for predicting the shear strengths of deep beams are still needed. By means of a large experimental database of 406 deep beam test results covering a wide range of influencing parameters, several shapes and geometry of STM and six state-of-the-art formulation of the efficiency factors found in the design codes and literature, the new STMs for predicting the shear strength of simply supported reinforced concrete deep beams using multiple linear regression analysis is proposed in this paper. Furthermore, the regression diagnostics and the validation process are included in this study. Finally, two numerical examples are also provided for illustration.

Lightning striking on a transmission tower induces high ground potential rise and high voltage at tower arms in which potential is normally at ground level, and subsequently causes overvoltage across an insulator string. If this overvoltage is higher than the withstanding voltage of the insulator string according to the v-t (voltage-time) curve, back flashover phenomena will occur and this event may cause outage. The main objective of this paper is to study the factors influencing the back flashover phenomena. The computer program PSCAD/EMTDC (Power System Computer Aided Design/Electromagnetic Transients including DC) is used to simulate lightning striking on a transmission tower 115kV. Lightning current, transmission towers, ground resistance, insulator strings and back flashover phenomena are modeled. Main simulations are lightning striking on different towers, different soil resistivity, different lightning current magnitudes and wave shapes, different locations, and different phase angles of source voltage. Simulation results show that the higher tower encounters higher induced voltage. A back flashover occurs at the top tower arm easier than at the middle and lower arms. The higher soil resistivity induces higher voltage. The larger lightning current magnitude impacts on higher induced voltage. The longer rise time of lightning current generates lower induced voltage. Lightning strikes directly on tower generate higher voltage than that of striking on overhead ground wires.

Ancient statues are cultural heritages that should be preserved and maintained. Nevertheless, such invaluable statues may be targeted by vandalism or burglary. In order to guard these statues by using image processing, this research aims to develop a technique for detecting images of ancient statues with missing parts using digital image processing. This paper proposed the effective feature extraction method for detecting images of damaged statues or statues with missing parts based on the Histogram Oriented Gradient (HOG) technique, a popular method for object detection. Unlike the original HOG technique, the proposed method has improved the area scanning strategy that effectively extracts important features of statues. Results obtained from the proposed method were compared with those of the HOG method. The tested image dataset composed of 500 images of perfect statues and 500 images of statues with missing parts. The experimental results show that the proposed method yields 99.88% accuracy while the original HOG method gives the accuracy of only 84.86%.

This study was aimed to increase the impact resistance of circular tubes reinforced by fiber reinforced plastic (FRP).The tube made of aluminum 6063-T5 with the D/t ratio of 25.40, 29.63, and 42.33. Outside surface of aluminum tube was reinforced by wrapping fiberglass/polyester. The fiber orientation angle were [0]3 , [45]3 , [90]3 , [0/902 ], [45/-452 ], and [90/02 ]. Then, they were tested under impact with cross head of 45 kg and speed of 6.26 m/s in axial direction. The result revealed that the impact resistance of the hybrid tube and aluminum tube trend to increase as the D/t ratio increases and The hybrid tube with wrapped angle of [0/902 ] was maximum mean load and higher than aluminum tube by 50.02, 45.14, and 52.03 % at D/t = 25.40, 29.63, and 42.33 receptively. Failure mode and crush behavior of hybrid tube were also presented and disused in this paper.

Social media sites have experienced an explosion in both the number of users and the amount of user-contributed content in recent years. There is the need for the solution for information overload in social media. In this paper, we focus on solving the problem of finding relevant Twitter users to follow and selecting only popular tweets to post, we have collected information about Twitter users, particularly the number of influential users who are followers, the number of general followers, and the number of tweets that are frequently retweeted. Then we used such statistics information to compute the user rankings. In addition, we also created a Twitter account to automatically post only tweets that have been retweeted many times. Based on the survey result and using the Spearman’s rank correlation coefficient, the recommended Twitter users suggested by the system have proven to be popular and pertinent, and the rank order by the proposed system has a statistical significant degree of similarity with the user survey result.

Currently the amount of web data has increased excessively. Its metadata is widely used in order to fully exploit web information resources. This causes the need for Semantic Web technology to quickly analyze such big data. Resource Description Framework (RDF) is a standard for describing web resources. In this paper, we propose a method to exploit a NoSQL database, specifically MongoDB, to store and query RDF data. We choose MongoDB to represent a NoSQL database because it is one of the most popular high-performance NoSQL databases. We evaluate the proposed design and implementation by using the Berlin SPARQL Benchmark, which is one of the most widely accepted benchmarks for comparing the performance of RDF storage systems. We compare three database systems, which are Apache Jena TDB (native RDF store), MySQL (relational database), and our proposed system with MongoDB (NoSQL database). Based on the experimental results analysis, our proposed system outperforms other database systems for most queries when the data set size is small. However, for a larger data set, MongoDB performs well for queries with simple operators while MySQL offers an efficient solution for complex queries. The result of this work can provide some guideline for choosing an appropriate RDF database system and applying a NoSQL database in storing and querying RDF data.

This paper proposed a nonlinear finite element model to investigate mechanism and behavior of the concrete columns confined with metal sheet. Three dimensional modeling was chosen. Concrete was modeled using the Drucker-Prager yield criterion and a softening function, whereas the Von-Mises yield criterion was chosen for metal sheet. Between both materials, a set of interface elements was inserted to represent layers of the bonding material. The results showed that the finite element model could model the behaviors that were observed from the laboratory experiments, and could capture the mechanisms that were not noticed in the laboratory experiment as well.

Insulin-like growth factors (IGFs) are hormonal proteins which share some structures with insulin but they are different in functions. IGF system is complex and they can regulate cellular communication and response to environmental change. IGFs are endocrine, paracrine and autocrine, they can modulate many cells and organs in the body. IGF-I plays important role in growth and reproductive performance while IGF-II involves in quality of pork. Using feed additives that can stimulate IGF-I production may be useful to indirectly increase growth of piglets and enhance reproductive performance in sows. [ABSTRACT FROM AUTHOR]

Isolation of bacterial strains from the gastrointestinal tract by 45 samples giant freshwater prawns weighing 30-40 grams, found bacteria in 327 isolates. These were screened for antibacterial activity against shrimp pathogenic Vibrio harveyi and Vibrio parahaemolyticus by the clear zone around the colonies. 118 and 19 bacterial isolates, were found the antibacterial activity against pathogenic Vibrio harveyi and Vibrio parahaemolyticus, respectively. The results demonstrated that highest antibacterial activity was shown by seven strains, named PBKS289, PBKS292, PBKS92, PBKS10, PBKS304 and PBKS91. These bacteria were PBKS289, PBKS292, PBKS184 PBKS92, PBKS10, PBKS304 and PBKS91 grew well in a medium containing 0-5% (w/v) bile salt 0-9% NaCl (w/v) and pH 5-10 except PBKS92 could tolerate pH 3-10. The reults support the approach of screening using probiotic bacteria for activity against Vibrio species. The probiotics have a good effect on survival when used as a food in prawn culture. Moreover probiotic bacteria can reduce the need to use toxic chemicals and antibiotics in prawn culture. [ABSTRACT FROM AUTHOR]
