Повний текст джерелаThis thesis deals with the construction of particular solutions of traveling wave or plane wave for different equations partial derivative (EDP) and in particular the Frenkel-Kontorova model and a regularized wave equation. This memory is structured as follows. The chapter 1 is preserved for a general introduction in which i present a physical motivation and a abstract of my work. In chapter 2, I interested to the study the existence and uniqueness of traveling wave solution for the accelerated Frenkel-Kontorova model. This model consist in a system of ODE that describe the motion particles in interaction. The most important applications ihave inmind in the motion of cristal defects called dislocations. For this model, i prove the exxistence of traveling wave solutions under very weak assumptions. The uniqueness of the velocity is also studied as well the uniqueness of the profile which used ddifferent types of strpng maximum principle. As far as we know, this is the first result concerning traveling waves for accelerated, spatially discrete system. This chapter is an article published in the Journal Dynamic and Differential Equation:Existence and uniqueness of traveling wave for accelerated Frenkel-Kontorova model, Journal of dynamic and Differential Equation : Volume 26, Issue 24 (2014), page 1133-1169. In chapter 3, i interested in the numerical homogenization of fully overdomped frenkel-Kontorova model. I present two methods for computing the effective hamiltonian : large time method and Newton-like method. Some simulations of the effective hamiltonian are provided. Le chapter 4 is preserved to the study a wave equation in a periodic medium. Under certain assumption, i construct a plane wave like solution, and show that this solution satisfy some properties. I define a non- local operator and a term corrector in order to control the oscillations of the solution in space and in time. We prove the construction of a plane wave like solution for the approched problem using the notion of viscosity solution

This study aimed to investigate the types and sources of misconceptions about aqueous solution held by pupils at an elementary school. The purposes were: 1) To develop a suitable instrument related to misconceptions on aqueous solution among the 4th and 6th-graders. 2) To investigate the differences of the misconceptions on aqueous solution held by 4th and 6th-graders. 3) To investigate the differences of the misconceptions on aqueous solution held by different genders. 4) To investigate the types and sources of the misconceptions on aqueous solution held by elementary pupils. 5) To investigate the influences of the content of the textbooks and teaching materials used in the science subject on the misconceptions on aqueous solution held by elementary pupils. The goal of the initial stage of the study was to develop a three-tier diagnostic instrument (TTDI) of computerized aqueous solution concepts. A total of 341 fourth and sixth grade pupils who were selected randomly from six classes at an elementary school in Taipei were tested. The purpose of TTDI was to examine the misconceptions about aqueous solution held by the elementary school pupils. Phase II: Based on the data collected in phase I, there were two sets of pupils selected from each class with a total number of 160. By analyzing the textbooks and group interviews, researchers further investigated the types, modes, and causes of the misconceptions about aqueous solution held by elementary school pupils. The result were: 1) The method of the TTDI with the application of computers was developed in this study. The TTDI has been reviewed and suggested by two experienced science education experts and four senior teachers, has been proven to be scientifically logical and effective. The test of TTDI also ensured the benefits of minimizing the interferences among the questions, enhancing participation, reducing costs, and saving valuable resources. 2) Based on the data analysis using T-test, there were significant differences between the 4th grade and the 6th grade pupils on the correct percentage of the questionnaire toward the aqueous solution concepts. 3) Gender played an important role in these tests. Female pupils scored significantly higher than their male peers. Judging by the average score, the effect of gender was not only found in the 6th grades, but is also is true with the 4th grades. 4) Through tests and interviews, the researcher categorized the misconceptions of aqueous solution into eight types and attributed its causes to the following. a. Reliance on the direct and subjective observation. b. Lack of scientific knowledge. c. Confusion caused by similar terminologies or concepts. d. Experiences derived from daily life. e. Language barrier. f. Influence of the multimedia. g. Misleading by the instructors. h. Influence of the textbooks. 5) From the extensive interviews with the pupils, we found that the misconceptions of the pupils may be also derived from the obscure contents and pictures in the textbooks. From the findings of this study, the researcher recommended textbook authors and elementary science teachers to have an extensive understanding of the misconceptions about aqueous solution among the elementary school pupils before preparing the teaching materials or giving out instructions. Then they can better help the elementary school pupils learn the concepts and gain knowledge of aqueous solution.

ABSTRACT The main purpose of this study was to explore the process of types of solution activities of multiplication word problems in the second grades. A sample of 185 subjects was asked to write down their solution activities in written tests before instruction and after instruction. Six students that were selected because of their learning ability were interviewed individually to probe their process in six different stages. And then, document analysis was used for these collected documents. The result of written tests indicated that there were five correct types of solution activities and the process of second graders'' types of solution activities was from additive calculation before instruction to multiplication calculation after instruction. The result of interviews indicated that the five correct types of solution activities could be divided into 13 subcategories. Moreover, the change pace and the process of types of solution activities were different from student to student, even the pace and the process of the two students in the same group in the same stage were different. The incorrect types of solution activities were more units, fewer units, additive, subtractive, transpose, blank and others. The possible reasons of incorrect types of solution activities were thoughtlessness, the effect of old experiences, misunderstanding of problems and misunderstanding of multiplication. In addition, analysis of types of problems and the effect of numbers'' sizes revealed the types of solution activities were different in three different types of problems and three different sizes of numbers.

Discharges in solution provide the possibility to generate reactive species in liquid phase in demand. The discharge behavior has been proved highly relevant with the behavior of bubble where the plasma is ignited, however the methods to actively manipulate the bubble dynamics and composition are still limited. In this study, strategies to tailor the plasma behavior via different power types are proposed. Unlike previous study in which plasma was driven by a direct-current power, a time-varying voltage was used to ignite the plasma. Two distinct bubble modes can be observed by adjusting the applied voltage and frequency: at 150 V, when a relatively low frequency (e.g. 50 Hz ) is used, the plasma is sustained inside a gas bubble with diameter of few mm; when a relatively high frequency (e.g. 500 Hz) is used, a jetting flow is observed. Depending on the bubble dynamics, we therefore called them as bubble and jetting mode, respectively. According to our study, it is known that frequency serves as an effective factor to control the heating in the vicinity of electrode surface, thus influencing the bubble and plasma behavior. The current and electron density in plasma are changed in response to the frequency. However, when plasmas are driven by an AC power source, plasmas are ignited by positive and negative polarity alternatively, and thus three issues are raised, namely damage of electrode, plasma instability, and poor power efficiency. A rectified AC power source was used in order to further improve the system. For both bubble mode and jetting mode, the discharge current for positively rectified AC- (PRA) driven plasma is only one tenth of that for negatively rectified AC- (NRA) driven plasma. The power consumption for PRA-driven plasmas is at least one order lower than that for NRA-driven plasmas. The result shows PRA-power is ideal to sustain the plasma. Finally, in order to control the gas composition, a bipolar pulse power source with adjustable positive and negative pulse width and amplitude was used to independently control the gas bubble formation and plasma ignition. Negative pulse with voltage from 0 to–80 V is used to generate the electrolytic gas bubble where plasma is formed and 600 V positive pulse is used to ignite the plasma. By this approach, the extension of plasma occurrence time in the positive pulse duration, the drop of peak electrolytic current, and the increase in relative H emission intensity are observed. These results suggest that by manipulating the driven power types, the gas composition and the discharge behavior can be effectively tailored.

Taiwan's foundry industry has been developing for nearly 50 years. It has always been to provide solutions based on the foundry model, so that the pricing basis for the products has always been based on the basis of the cost and the basic price of the competitors. The profit margin is very limited. Taiwan's foundry industry has also faced many problems in recent years, including work environment, talents and technological problems. In addition to changes in the demographic structure of Taiwan, a part of the reason is that the current state of the industry didn’t attract young people to work. Only by upgrading and transforming the industry can improve technical capability, profit, and change the current state of the industry. The government encourages the development of high-value casting products. The development of more stringent industrial conditions such as machine tools, automobiles, aerospace, and agricultural machinery are one of the ways that products can be value-added. Products can have high added value that the key lies in the connotation of the solution provided by the foundry. This study attempts to sum up four matrixes of solution types from the two dimensions of proposal capabilities and delivery capabilities from the perspective of literature, and to define pricing principles for solution types according to customer value connotations. At the same time, the foundries of different industries are the empirical objects. The selected companies are representative and influential in this industry to verify and complement theoretical deficiencies. Finally, the verification results show that the different types of solutions have different customer values, so the pricing basis for the products varies will affect pricing principle of the products. Finally, it will provide the forward practical suggestions to allow companies to face transformation or future development. Only by changing the solution delivery model can the price of products to increase profitability. The direction must strive for is to improve our proposal capabilities and delivery capabilities.

Early Taiwan machine tool industry make a figure in the international market with outstanding cost-effective advantage. But in recent years, faced dramatic changes in the environment, the economic downturn and competitors oppression, so that the living space were crushed. Taiwan's machine tool industry should rethink its position. In addition to focus on manufacturing and pursuit of lower costs previously, it should be converted through provide customers with a comprehensive range of solutions to meet customer needs and increase their value added. Simultaneously, thinking about how to earn more profits with pricing. Through literary review and the value of the enterprise provide customer with solution as well as customer obtain from the solution, this study proposes three pricing models of solution type: ” labour service- entrust “,” labour service-value ”,” proposal-value ”. In order to verify and complement our theory of pricing models, we choose three machine tool enterprises to understand the process they provide customers with complete solutions. Finally with KEYENCE case study as an extension of the discussion. The empirical results show that providing a complete solution can indeed create more value for customers, but pricing in the machine tool industry mainly consider the value based of the function on the machine itself. But in the solutions business field, is still recognized that the key of value creation. Therefore, it has a theoretical and substantive meaning, also expected to find a way out for Taiwan's machine tool industry to overcome the difficulties encountered currently.

Taking an overview of history, we can find that technology and media always influence education deeply. Computers integrate media, which changes unilateral media into multi media. And digitized multi media transforming into super media by the help of internet stores in the world wide webs. World wide webs make learning jump out of the limitation of time and space, the chance of learning become easier, and also change the mutual role of teachers and students. Teachers will not be the only source of knowledge. Teachers have become pilots leading students constructing their own knowledge efficiently without being overloaded and missing in the vast world wide webs. The current internet material are almost browsed by letters and pictures with background music. We wonder if the outcome will be the same when students learn through their own perception? The study takes the approach of semi- experiment and get samples from 211 4th grade primary school students to explore the influence of perceptional learning style and different material demonstration for students to learn " Solution of Acid/Alkaline Base" We get the points as follows: 1. There is no apparent difference between different material demonstration and learning outcomes. The factor influences learning outcomes is related teaching design, having nothing to do with the media being used. 2. There is apparent influence for different learning style on learning outcomes. The learning outcomes of audio/video centered or video centered students are better than audio centered students. The Video centered is better than not video centered.
