El carácter voluntario de los donativos indianos, entre la praxis institucional y la construcción del consenso (siglos XVI-XVII)
Authors: De Nardi Loris
Published: March 2018

Al leer las principales investigaciones relativas a los donativos voluntarios, solicitados por los Habsburgo de España a lo largo del siglo XVII, es posible llegar a dos conclusiones principales. Primera: la petición del donativo, si bien tuvo lugar a lo largo de los reinados de Carlos V y de Felipe II, se dejó de lado durante el reinado de Felipe III, y se convirtió en sistemática sólo bajo Felipe IV. Segunda: en la práctica el donativo no tenía nada de “voluntario”, a pesar de que oficialmente se le denominara así. Estas investigaciones aún no permiten desarrollar una regla general válida para toda la monarquía católica, ya que todas toman en consideración un único ámbito geográfico, la península ibérica. En consecuencia, no es posible afirmar que los donativos pedidos por la corona en las demás áreas que conformaban el imperio español se caracterizaban por las mismas dinámicas, como por ejemplo las Indias.
Discos sediciosos y volantes prohibidos. La muerte de Obregón entre la censura y el ingenio popular
Authors: Díaz Frene Jaddiel
Published: March 2018

Sucesos como el asesinato de Álvaro Obregón y el juicio contra José de León Toral formaron parte de un proceso político extraordinario que impactó la vida cotidiana mexicana. Lejos de reconstruir una historia de estos acontecimientos desde una óptica política, en el presente artículo intentaremos acceder a una historia de la opinión pública popular teniendo como eje central las representaciones y los usos sociales de dos medios escasamente abordados como los fonógrafos y las hojas volantes. Mediante estas fuentes privilegiadas, proponemos acceder tanto a las voces y las prácticas de los sectores populares como a los mecanismos gubernamentales de censura. Documentos judiciales, discos fonográficos, hojas volantes, testimonios periodísticos, fotografías y obras de teatro acompañarán esta travesía en la que se interceptan la letra impresa y los universos sonoros, las lecturas subversivas y las escuchas callejeras.

Authors: Santos-Roldán Luna , Palacios-Florencio Beatriz , Berbel-Pineda Juan Manuel
Published: March 2018

Obtaining information is key to business success. However, to achieve this is generally costly (in both monetary and time terms). This is complicated even more for those firms which need information from foreign markets. Moreover, it has to be considered that information based on secondary data is not always available or easy to get, and that to attain it based on primary data requires a great effort. The aim of the present research is to show a procedure which helps SMEs to obtain this market-relevant information. To do so, a new methodology is used which enables these firms to know in broad terms how consumers of the different country-markets behave, as well as getting information related to the product's commercialization. A pilot experience has hence been used, whose target population is tourists in the city of Seville. A sampling session of the product was carried out, via which, and through a questionnaire, information was gathered concerning the countries of origin of the participants in this study. Its flavor is appreciated by the consumer in the four varieties considered, and in appearance, the product also has a very good acceptation. It is worth considering what is going to be the packaging for the product's commercialization and its labeling. The different varieties also have their markets and all of them should be adapted to the local tastes.

A Study on Cultural Capital and High-Risk Behaviors of College Students in Iran
Authors: Naseri Samaneh
Published: March 2018

The term cultural capital has gained a widespread popularity as an analogy with economic capital, and capitalism rules and debates since the early 1970s. Essentially, cultural capital is not inherited, yet it is achieved through personal endeavors. Acquisition of cultural capital demands an incessant and hard work in addition to lifelong learning and acculturation. Hence, the present study examines the relationship between forms of cultural capital and high-risk behaviors of Iranian college students. The impact of each form on the incidence of high-risk behaviors is measured. A survey consisting demographical items, and items assessing cultural capital and tendency towards high-risk behaviors are applied. The results suggest a meaningfully negative relationship between sub-types of cultural capital and high-risk behaviors among undergraduate students in Iran. So, the author concluded that with an increase in cultural capital and the sub-types, the incidence of high-risk behaviors decreases consequently.
Empirical Identity as Dimension of Development in Africa: With Special Reference to the Igbo Society of South-east of Nigeria
Authors: Nnebedum Chigozie
Published: March 2018

Identity, as discussed in this paper, is seen as a phenomenon which is constantly changing under certain circumstances. From empirical point of view, the identity of man is influenced by the environment through experience and unconscious socialization; it is continually modified by the individual’s encounter with the world. The aim of this work is to analyse the intricacies involved in understanding the situation and mentality of the Igbos as far as identity is concerned and to determine how this hampers or helps in the development of the Igbo/African society. In this work ‘identity’ as a means of development with regard to the Igbo people of South-East Nigeria is treated. The work is methodically qualitative. It analyses literatures and different views on identity and tailors the discussion of development along the lines of hermeneutical approach to subjective experiences. The Igbos and Africans find themselves sometimes in the danger of a mixture of identity. This is the case with most of the Igbo people who are scattered all over the world and who are becoming more foreign in their trends and ways of life. Being unable to maintain a definite identity, one is lost in the politics of development. Those who still hang on to pure imitation of the western life are jeopardizing their autonomy and by extension, frustrating development of the African society. Rediscovering the Igbo/African Identity and putting it to the service of development in the African continent is the task of the Africans themselves.

Authors: Jobanputra Jalpa , Kotwal Chetan
Published: March 2018

Optimal utilization of transmission system without congestion in the network is most important as congestion can violet the security of the system. Sufficient amount of reactive power support needs to be provided in the system in order to maintain the power flow limits on transmission lines and voltage limits at bus bars. This Paper focuses on analysis of congestion occurrence with N-1 contingencies for line flow limits in case of line and generator outages using linear sensitivity factors and congestion management using series compensation. Generation shift factor and line outage distribution factor are used to find sensitive lines and series compensation in two stages are applied to the most sensitive lines to relieve congestion. Standard IEEE 6 bus test system is used to analyze contingencies and congestion mitigation. All the simulations are performed using power world simulator version 19.0. Mathematical calculations are also performed for the same 6-bus system for validation of results.

Published: March 2018

Solar based electronic fences use the principle of converting solar energy into electrical energy and giving electronic shock while touching the fences. Electronic fences are used at many places such as forest area, farm, government area etc. to protect them against animals and thefts. It consists of small components which used to convert solar energy to electrical and further will convert DC voltage to AC voltage and provide shock to the person who is touching the fences. The solar energy is converted to the electrical energy which is in the form of unregulated DC voltage. This unregulated DC voltage is converted to the regulated DC voltage and further converted to the AC voltage using inverter. This inverted high AC voltage and small current helps to give short but sharp shock so animals and thefts stay away from that area. The change in current is sensed and gives alert to the owner. Owner will know who is entering in the farm by the device IR sensor which senses the entry of the person.

Published: March 2018

This paper proposes energy efficient LEACH protocol for secure data transmission for wireless networks. The proposed work uses Networks Simulator – NS2.27 for the simulation of cluster based routing protocol LEACH in wireless sensor network. The work is to enhance the performance of LEACH in terms of energy saving and secure data transmission. Instead of random selection of Cluster Head (CH) the selection method is based on residual energy and vicinity of the node. With this hybrid approach, the node, which is eligible for the CH, will become cluster head and it enhances the performance of traditional LEACH. Traditional LAECH does not support secure data transmission and authentication of nodes in the clusters. By adding security between CH and CM using XOR function and key management, secure data transmission and authentication is carried out for selected application where security is the most important aspect. The proposed LEACH enhances lifetime of the wireless sensor network with security.

Published: March 2018

An ideal fixture should maximize the stability and locating accuracy of workpiece and also minimize deformations during operation. The present work aims at designing a machining fixture for boring and face milling operations of helical gear boxes and attempts to provide a solution which gives accurate workpiece control. These gear boxes are manufactured as per DIN 3664 with class 6. Generally, the dimensional and geometric tolerances for features are of the order of 20 microns. Hence, the fixture design demands accurate workpiece control. The accurate workpiece control can be obtained by determining the position of locators and clamps which yields minimum deflection of the workpiece. In this paper, optimization of the positions of the locators and clamps is carried out using Genetic Algorithm (GA) with ANSYS Parametric Design Language (APDL). The prediction of the positions of the locators and clamps is done by using Artificial Neural Network (ANN) and Response Surface Methodology (RSM) which is used as input data for Genetic Algorithm. A systematic process is developed to minimize the workpiece elastic deformation and to optimize the locators and clamping positions using Genetic Algorithm and Finite Element Analysis. The procedure developed can be used by industry to develop fixture for any complex geometry of workpiece.

At present, power demand is increasing day by day so we have to transfer more power and for this we must have to improve stability limits of our power system. In this paper application of static synchronous series compensator (SSSC) for enhancement of power system stability is throughout investigated. SSSC is effectively utilized for power flow control in the power system. A SSSC-based damping controller is proposed for power oscillation damping and to improve the rotor angle stability. A improved control signal can be superimposed as a power flow control signal for SSSC damping controller to improve the rotor angle stability and power oscillation damping in system. Speed deviation of rotor is taken as the input signal to the SSSC damping controller. A single machine infinite bus system (SMIB) with SSSC is simulated in MATLAB/Simulink software. Simulation results shows the effectiveness of this controller for power system stability enhancement under different fault conditions.

To improve the hydrodynamic performance of the centrifugal pump, in present work a DOE technique Taguchi L9 orthogonal array experiment was carried out to optimize the impeller design parameters. The Navier-Stokes equations for three-dimensional steady flow is solved by computational fluid dynamics (CFD) code. The experimental test result of the original pump was compared with the data predicted from the numerical simulation. The comparison shows the closeness of predicted values with the experimental values, leads to validation of the numerical model under the specific range of operating conditions. Four geometric parameters of impeller were chosen as the variable factors viz. Number of blade, Impeller blade outlet angle, Impeller blade Inlet angle and Impeller blade wrapping angle. According to L9 orthogonal array, nine impellers were modelled using CAD modelling software and CFD analysis is carried out using ANSYS CFX. The impellers were equipped with the same volute during all the simulations. The modelled impellers were simulated by the same numerical method, which has been validated. The best parametric combination for higher efficiency is analysed finally. Results show the improvement of 4.25% higher efficiency compared with the original pump. The geometry selected for this model may be the best one to get the maximum efficiency for such pumps.

Authors: Iyer Jyoti , Suthar Bhavik
Published: March 2018

In the current deregulated environment, determining loadability to various security limits is of great importance for the secure operation of a power system. The conventional P-V and Q-V curves are used to determine the voltage stability margin. This paper proposes to find the relationship between P and Q for a constant voltage on a particular bus using a contour evaluation program. The flexibility of this program allows generation of a family of curves which show the amount by which the reactive power loading on a particular bus needs to be modified so as to keep the voltage constant on that bus.

Casting process deals with the metal in the molten state. When the molten metal is poured into the mold box, Smooth and turbulence less flow with appropriate velocity is need to be ensured. Type of flow while pouring the molten metal has significant influence on the end characteristics of casting. Inefficient metal flow can result in error beyond altering the desired characteristics of casting. Dross formation while pouring the metal has direct connection with the type of flow of molten metal. In short, one cannot neglect the flow of molten metal on other hand expecting sound casting formation. Gating characteristics directly deals with the type of flow expected while pouring. To provide desired flow is one of the functions of efficient gating system. But it is very difficult to consider the flow characteristics while actually designing the gating system. Computer technology has taken leap to aid foundry engineer in control of metal flow. Simulation soft-wares have been equipped with provision of flow analysis while designing the Gating system.

Authors: Patel Ripal , Pandey Shubha , Patel Chirag , Paul Robinson
Published: March 2018

Flicker is the most common and an intolerable blemish present in signal processing world that leads to distortion in the transmitted frame of a video string. To dodge such misinterpretations a technique for detection of the flickering frame in a video is depicted in this research. Earlier methods were based on removing flicker by calculating the threshold of the consecutive frame difference and then finding the flickering frame. The proposed method in this research includes finding flickering frame using neural network concept. Therefore, the advantage of the practice disclosed here is that it removes the tedious calculation part of the threshold value and thereby the computational part becomes easier with added accurate result.

With the increase in the number of thefts, robberies and encroaching in the world, the existing security system is not sufficient. Hence to circumvent this problem the demand of bio-metric systems is increased, as they provide more dependable and effective means of identity confirmation. One such bio-metric security that has seen an uproar in the recent years is the gait identification. Gait recognition targets fundamentally to address this problem by recognizing people based on the way they walk. First of all, silhouette of the persons is extracted. Moreover, step size of the person is considered as unique feature for representing gait and effectively classify the person based on gait. Finally, features are feed to neural network for classification. The proposed approach gives better accuracy.

Blower is used to deliver the air or gas with an appreciable rise in pressure against the flow resistance. It plays an important role in various industries for air-conditioning systems, furnaces and dust or fume extraction systems. The backward inclined blade centrifugal blower was considered for study and analysis. The parameters affecting performance were determined and important parameters were selected. For centrifugal blower, both impeller and casing parameters are considered for CFD analysis in ANSYS, where model was prepared in Creo2.0 parametric and CFD results were validated with the help of experimental results. For CFD analysis of models k- ɛ turbulence model was used. Then range of parameters was used for doing DoE by Taguchi’s method and detailed study of given blower was carried out. Models given by DoE were analyzed to get their performance and optimal model was found out which has 23.07% higher performance than current centrifugal blower.
