Resolver, due to its reliability and durability, has been used for the aim of shaft position sensing of military rotary systems such as tank turrets and gun stabilization platforms for decades. Ready-to-use resolver-to-digital converter integrated circuits which convert the resolver signals into position and speed measurements are utilized in servo systems most commonly. However, the ready-to-use integrated circuits increase the dependency of the servo system to hardware components which in turn decrease the efficiency and flexibility of the servo system for changing system structures such as for changing resolver carrier frequency or changing position and speed sensors. The proposed solution to increase the efficiency and flexibility of the servo system is a software-based resolver-to-digital converter which does not require aforesaid special hardware components and presents a complete software-based solution for the conversion. The proposed software-based resolver-to-digital converter makes use of common programmable hardware v components, that is, FPGA and DSP which form the heart of the servo controller technology in recent years. The proposed structure for the conversion has three components. The first component is the signal conditioner which minimizes the disturbances coming from the resolver signals as harmonic distortions and noise. The second component, the phase-sensitive demodulator, as the name implies, is responsible for phase-sensitive demodulation of resolver signals. The third component is the estimator filter. In order to determine the optimal estimator filter, five different estimator filters with the aforesaid two components are implemented in ASELSAN&rsquo / s stabilized gun system STAMP and they are compared in terms of both estimation performance and computational complexity. The implemented filters include nonlinear observer type filter which is already proposed in the literature for resolver conversion, tracking differentiator adapted to resolver conversion and kalman filters adapted to resolver conversion in different forms such as linear kalman filter, extended kalman filter and unscented kalman filter. At the end of the study, stability and sensitivity analyses are also performed for the proposed system.

La presente investigación aborda el tema de la interacción verbal Docente-Estudiantes y su relación con la competencia para resolver problemas en la asignatura Matemática para los Negocios I, en estudiantes del I ciclo de la Facultad de Administración y Negocios de la Universidad Tecnológica del Perú (UTP), periodo académico 2014. Se utilizó dos diseños de investigación: por un lado el estudio de caso mediante la observación no participante y; por otro, el diseño descriptivo correlacional de base no experimental y de corte transversal. Se trabajó con una población de 285 estudiantes del I ciclo, matriculados en la asignatura Matemática para los Negocios y se utilizó el muestreo no probabilístico de tipo intencional porque el objetivo es estudiar a profundidad a dos grupos de docentes con sus respectivos estudiantes. El tamaño de la Muestra es de 32 estudiantes ubicados en dos aulas de 16 estudiantes cada uno quienes asistieron con regularidad a las clases. Para el análisis de la variable interacción verbal Docente-Estudiantes se utilizó el modelo de Análisis de la Interacción de Flanders (FIAC) basado en 13 categorías: ocho de comunicación verbal del Docente y cinco de comunicación verbal del Estudiante. Para ello se utilizó fichas de registro y escala tipo Likert de cinco alternativas de respuesta. Este instrumento fue validado por juicio de Expertos. Asimismo, luego de los resultados de la observación en el aula se procedió a identificar los tipos de diálogo Docente-Estudiantes en base a la tipología propuesto por Villalta, Martinic & Guzmán (2011) según el número de intervenciones y tipo de exigencia cognitiva. Los instrumentos utilizados que midieron la variable competencia para resolver problemas son la prueba escrita y el cuestionario. El primer instrumento evaluó dos dimensiones: a) habilidad conceptual y b) habilidad procedimental; por su parte, el cuestionario logró medir la tercera dimensión: c) habilidad actitudinal. Como resultado del presente estudio se demuestra que existe relación entre la Interacción verbal Docente- Estudiantes y la competencia para resolver problemas en la asignatura Matemática para los Negocios I, en estudiantes del I ciclo de la Facultad de Administración y Negocios de la Universidad Tecnológica del Perú. Es decir, a medida que la Interacción verbal Docente-Estudiantes aumenta, la competencia para resolver problemas de los estudiantes también aumenta. Este es el caso de la sección 01, donde la correlación es positiva y alta (r=0.825; p=0.01) lo que implica que a mayor Interacción verbal Docente-Estudiantes mayor será la competencia para resolver problemas. En la sección 09, la correlación es menor en comparación a la sección 01, pero sigue siendo alta (r=0.693; p=0.03). Palabras clave: Interacción verbal Docente-Estudiantes, competencia para resolver problemas, proceso enseñanza-aprendizaje. / --- This research addresses the issue of verbal interaction Teacher-Students and their relationship to the competition to solve problems in Mathematics for Business I, students of the first cycle of the Faculty of Business Administration at the Technological University of Perú (UTP) academic year 2014. Case study on the one hand by non-participant observation and: two designs research was used secondly, the descriptive correlational not experimental design and crosssectional basis. We worked with a population of 285 students of the first cycle, enrolled in Mathematics for Business and the non-probabilistic intentional sampling was used because the objective is to study in depth two groups of teachers with their students. Sample size is 32 students located in two classrooms of 16 students each who regularly attend classes. Eight Teaching verbal communication verbal communication five Student: For the analysis of verbal interaction Teacher-Student Variable Model Analysis of the Interaction of Flanders (FIAC) was used based on categories. For this registration cards and five Likert scale response alternatives used. This instrument was validated by expert judgment. Also, after the results of the classroom observation proceeded to identify the types of Teacher-Student dialogue based on the proposed Villalta, Martinic & Guzmán (2011) as the number of interventions and type of cognitive demand type. The instruments used to measured variable to solve competition problems are the written test and the questionnaire. The first instrument evaluated two dimensions: a)conceptual ability b) procedural skills; For its part, the questionnaire was able to measure the third dimension: c) attitudinal skills. As a result of this study it shows that there is a relationship between verbal interaction teacher-students and the competence to solve problems in Mathematics for Business I, students of the first cycle of the Faculty of Business Administration at the Technological University of Peru. That is, as the verbal Teacher-Student Interaction increases, competition for solving problems of students increases. This is the case of Group A, Section 01, where the correlation is positive and high (r = 0.825, p = 0.01) which implies that the greater verbal interaction Teacher-Student will be greater competition to solve problems. In group B, section 09, the correlation is less than the group A but remains high (r = 0.693, p = 0.03). Keywords: Verbal Interaction Teacher-Student competition to solve problems, teaching-learning process.

Within the framework of the traditional sociological question, how the legal system is related to the society, the aim of this study is to treat the legal system as a conflict resolver. More specifically, the following questions will be treated:1.Which categories of people and which categories of organizations are as parties using the court for settling conflicts and in what types of conflicts do they act in this way?2.Howdoes the legal utilization vary over time? May socio-economical, demographical, and legal conditions explain these variations?This study only deals with conflict resolution in courts of first instance, so called district courts.One aim has been to get a general view over to what extent Swedish courts are utilized as conflict resolvers, and how this utilization varies over time. The discussion is mainly based upon official statistics. To complete this discussion, an empirical study has been realized. This study is comparative. The conflict solving activities between 1940 and 1969 has been examined in the town courts of Umeå and Luleå. The data basis consists of official statistics and collected informations from cases finally dealt with in the two courts. A stratified random sample out of these cases has been made. As a result of theoretical and methodological considerations the sample consists of only certain types of disputes and crimes.As a general conclusion, one can state that disputes before the courts nowadays as earlier are concerning socially and economically strong persons. However one must notify that this study is just a case study with its limitations.Concerning criminal cases, expected results from the study are that the proportion of workers among the prosecuted is bigger than the proportion of prosecuted business leaders. Interesting however, is that the unskilled are well represented in the data material. This means a different picture compared to the distribution of plaintiffs in civil cases. The changes in character of the conflict constellations occured in the two towns at the same time as summary legal processes were introduced in criminal cases at the end of the 1940's. A bigger proportion of workers as prosecuted party is observed after that processual simplification. Pro-cessual simplifications of that kind seem to strengthen rather than to weaken the occupational bias among the prosecuted persons, at least in crime cases with an injured person involved.Concerning criminal cases, we have finally assumpted that during phases of social and economical stagnation both the number of prosecuted workers and the number of theft and drunkeness cases increases in the type of industrialized community that Luleå belongs to. In more socially and economically differentiated communities, like Umeå, the same type of development is more linked to phases of economical expansion. While increases in the pressure of temptation are widening the economical conditions for people, this may be the reasonable explanation to the variations in the conflict resolving activities in the courts between different local communities. Explanations, close to those used to explain criminal activity caused by poverty, may refer to local communities dominated by industry. / digitalisering@umu
