Analysis of Transient Stability of Superconductor Synchronous Generator at the Presence of Fault Current Superconductor Limiter
Get PDFOne of the most important principles in power networks is system stability. For maximum use of investments in generation, present day systems work at their highest capacity. In other term, they are always at oscillating state and this reduces power system stability drastically. An ordinary generator has some flaws such as small output power density and low efficiency especially upon high powers; however, superconductor generator has higher efficiency than ordinary generator, and similarly, has greater stability upon occurrence of oscillations in power networks. From other side, use of fault current superconductor limiter for rapid removal of fault and ameliorating the transient stability also is effective for generator protection upon fault occurrence. Given above questions, the necessity of study and offering an approach regarding transient stability amelioration, modification of oscillations as well as protecting generators upon fault occurrence seems to be necessary. Here, by modeling an ordinary synchronous generator with infinite bus and comparing it with equal conditions upon fault occurrence with a superconductor generator at the presence of fault current superconductor limiter, we examine the rotor kinetic energy oscillations upon fault occurrence using MATLAB software
Testing Efficiency Wages Hypothesis in Manufacturing Industries of Iran
Get PDFThe main objective of this study is to examine the efficiency wage theory for Iranian factory industries in the 2-digit International Standard Industrial Classification (ISIC) level in 2001-2011. According to the efficiency wage theory, which is in fact one of the New Keynesian Economists Theories in labor market, reduction of wage is not explainable even under stagnation conditions. This is because; with reduction of wage, the best laborers leave their job and this can decrease workforce productivity. Therefore, in this theory, there is direct correlation between wage and productivity. In other words, efficient wages can enhance productivity. In this study, panel data regression has been used to test the said theory. The results obtained from estimating different models show that efficiency wage theory is not confirmed for Iranian industries. In other words, higher wages can improve productivity and efficiency of laborers in factory industries of Iran

The involvement of students in various research activities connected to foreign language studies contributes to the formation of additional research competencies. In the article, the authors determine the organizational tasks, the types of Students”™ Scientific Research (SSR), the pedagogical conditions for the research competencies formation. Moreover, the authors assessed the research skills development within the framework of the SSR
Analysis of causative factors and cytokine status in traumatic injuries of the lower jaw and complications thereof
Get PDFThis paper presents the degree of incidence, ethiology, traumatic injuries structure, and assessment of local level of TNFα, IFNΠand IL-10 in patients with chronic posttraumatic osteomyelitis and simple jaw fractures. Among the causes for fractures, predominance of civilian trauma is revealed (82.5%) provided that the majority of injured (64.7%) suffered the injury under the influence of alcohol. Main factors aiding occurrence of pyoinflammatory complications in patients with fractures of the lower jaw are as follows: late request for quality medical assistance by the injured person; poor-quality of immobilization; presence of a tooth in the fracture cleft, and comorbidity. The research demonstrates that immunological indicators of mixed saliva reflect the dynamics of a local inflammation. It is found that the level of TNFα, IL-10 may be additional immunological markers for development of posttraumatic osteomyelitis of the lower jaw
Diagnóstico de las competencias a desarrollar en la asignatura Química General e Inorgánica: Caso Facultad de Ciencias Químicas de la Universidad de Guayaquil
Get PDFLa investigación se propuso diagnosticar la percepción de los estudiantes y profesores, en relación la situación actual de la enseñanza de la Química. Los sujetos de investigación, en el caso del presente estudio, fueron: estudiantes, profesores y directivos. Se aplicó una encuesta a 97 estudiantes y el mismo instrumento además de una entrevista se aplicó a 6 profesores y 3 directivoA partir del análisis de las preguntas que indagan sobre la pertinencia de los capítulos que aborda o debe abordar el programa de la asignatura de Química, se obtuvo que el mayor porciento de estudiantes estuvo de acuerdo con los capítulos actuales, pero además consideró necesario incrementar otros. Se observaron igualmente diferencias entre las respuestas de los estudiantes y los profesores. El mayor porciento de estudiantes consideró que los contenidos actuales se debían seguir impartiendo, solo pocos estudiantes consideran lo contrario. El criterio de los profesores no se comporta de la misma manera, estando en equilibrio los que consideran que son adecuados los contenidos como los que opinan lo contrario.Las diferencias entre alumnos y profesores en cuanto a la pertinencia de determinados temas o contenidos se hicieron evidente en varios ítems de la encuesta. Como investigadores sostenemos la posibilidad de que las mismas puedan deberse a que los estudiantes estiman el grado de dificultad de los contenidos a vencer y esto pudiera estar influyendo en su percepción, más que la necesidad de apropiarse de esos conocimientos y habilidades. Los entrevistados, incluido los directivos, aunque tuvieron contacto directo con la asignatura no estaban familiarizados, ni capacitados en el enfoque de la educación por competencia
Relación entre Código de í‰tica y Corrupción. Caso 15 Empresas Públicas y percepción de usuarios seleccionados
Get PDFLa ética en las empresas públicas es un bien preciado y discutido pues cada uno de los casos de corrupción ha desembocado en la función pública y su talento humano.El objetivo de la presente investigación consistió en determinar si los esfuerzos hechos en los últimos años con respecto a cambiar el imaginario de que la función pública es sinónimo de corrupción. Se analizó el Plan Nacional del Buen Vivir y el Código de í‰tica para instituciones públicas`. Instrumentos que sientan una base legal que debiera impedir la corrupción, pero se sabe que esto es ideal.Se tomó como muestra 15 empresas públicas, con sus jefaturas ubicadas en la ciudad de Quito y de las mismas a 150 servidores públicos de mandos medios, con el fin de identificar si conocen el código de ética y si lo aplican viviendo sus valores a cada momento dentro de su gestión.Se investigó igualmente 50 usuarios de estas dependencias públicas, de la ciudad de Quito para que se manifestaran en relación con el nivel de confianza que perciben de la Gestión Pública.La tarea de cambiar aún está en un arduo proceso, planteamos como hipótesis: “la percepción de la corrupción ha disminuido a pesar de los escándalos en los que están involucrados altos funcionarios de gobierno”
Face Recognition using the LCS algorithm
Get PDFToday, the topic of human identification based on physical characteristics is a necessity in various fields. As a biometric system, a facial recognition system is fundamentally a pattern recognition system that identifies a person based on specific physiological or behavioral feature vectors. The feature vector is typically stored in a database upon extraction. The main objective of this research is to study and assess the effect of selecting the proper image attributes using the Cuckoo search algorithm. Thus, the selection of an optimal subset, given the large size of the feature vector dimensions to expedite the facial recognition algorithm is essential and substantial. Initially, by using the existing database, image characteristics are extracted and selected as a binary optimal subset of facial features using the Cuckoo algorithm. This subset of optimal features are evaluated by classifying nearest neighbor and neural networks. By calculating the accuracy of this classification, it is clear that the proposed method is of higher accuracy compared to previous methods in facial recognition based on the selection of significant features by the proposed algorithm
Morphological and anatomical assessment of the nasopalatine canal in edentulous patients using cone beam computed tomography
Get PDFNasopalatine canal (NPC) is one of the most important anatomical structures in the anterior maxilla; therefore, it is necessary to advance our knowledge about its features for dental implant treatment in this region. The aim of the current study was to investigate the morphological and anatomical variations of the NPC using cone beam computed tomography (CBCT) in a subset of Iranian maxillary edentulous patients. Material and methods: The characteristics of the NPC were examined on CBCT images of 48 (29 males and 19 females with a mean age of 53.04 years) edentulous patients. The sagittal sections of CBCT images were used to examine the shape (funnel- like, cylindrical, hourglass- like and banana- like) and dimensions of the NPC canal (the length of the NPC, the diameter of the foramina of Stenson (FS) and incisive foramen (IF)) of the NPC) and buccal bone wall. The shape of the incisive foramen was assessed on axial sections of CBCT images and were categorized to round, oval, heart- shaped and lobular. Results: The mean diameter of FS and IF were 3.60 1.44 mm and 6.78 2.56 mm respectively. The mean length of the NPC was 12.70 2.22 mm and the width of buccal bone plate increased from the crestal to apical level. Cylindrical (50%) and round (58.34) were the most prevalent shapes of the NPC and IF respectively. The age and gender of patients did not have any significant effect on the shape and dimensions of the NPC (p>0.05).Discussion: The results of this study showed that morphological and dimensional characteristics of the NPC in edentulous patients are not affected by age and gender. However, further research is needed to confirm this finding among Iranian population
Efecto Crowding-Out en la Economía Ecuatoriana, 2000 – 2016
Get PDFLa teoría económica establece que la inversión privada mantiene una relación inversa con la inversión pública. Este fenómeno se conoce con el nombre de “Efecto Crowding-Out” o “Efecto Desplazamiento”, y, para que se presente, se asume que el sector público y privado compiten en la economía por recursos financieros. Como consecuencia, si el sector público incrementa su nivel de inversión, el sector privado verá su nivel de inversión disminuida. El presente trabajo busca evidenciar, con los datos disponibles, si el efecto desplazamiento se presenta en la economía ecuatoriana comparando la evolución de la Formación Bruta de Capital Fijo privada frente a la Formación Bruta de Capital Fijo pública. Para realizar este análisis, la presente investigación tiene un enfoque cuantitativo, la metodología a utilizar es no experimental de campo, de tipo descriptiva. La técnica de recopilación de datos se realiza mediante observación de variables y sistematización. Los resultados demuestran que existe presencia de efecto crowding-out en la economía nacional, específicamente la FBKF privada tiene una elasticidad promedio de -0.23 con respecto a la FBKF pública. Las conclusiones permiten dar paso a otros trabajos que analicen políticas fiscales y de inversión por parte del gobierno central
