El debido proceso como derecho fundamental en el sistema de justicia peruano
Authors: Bardales-del-Aguila Lionel
Published: January 2023

La teoría del derecho procesal surge en Alemania e Italia en la segunda mitad del siglo pasado, distinguiéndose diferentes concepciones sobre la doctrina general del proceso o del derecho procesal. En un primer momento, se postuló un sistema unitario; paulatinamente este se fue desprendiendo en sus diferentes ramas: se inició con los derechos procesal civil y penal, luego el derecho procesal administrativo, el derecho procesal laboral, y una de las más actuales es el derecho procesal constitucional. (Fix-Samudio, 1976). Según Chiovenda y Calamendrai, los tres conceptos fundamentales de la ciencia procesal son:  acción, jurisdicción y proceso y ellos engloban todos los procesos.

Published: January 2023

El techo de cristal es un concepto que se desarrolla a lo largo de la historia que da inicio con la inclusión laboral de las mujeres al mundo laboral, pero que solo hasta hace algunos años es descrito por diferentes autores como la brecha y barreras invisibles que existen para que las mujeres accedan a los diferentes cargos de alta dirección en las organizaciones, impidiendo el desarrollo personal y profesional debido a la imposición social de diferentes estereotipos que afectan de forma directa a las esferas sociales y culturales. En la presente investigación se analiza cuáles son las diferentes barreras invisibles que impiden el acceso de forma igualitaria a cargos administrativos públicos de alta jerarquía para las mujeres, vulnerando los derechos de las mismas, presentando afectación en todo su desarrollo. Por otra parte, se hace referencia al marco normativo conformado por una serie de leyes, normas, resoluciones y artículos que ampara y garantiza de forma directa la mitigación de la paridad de género, con el fin de lograr el desarrollo e igualdad de oportunidades que conlleven al crecimiento profesional y personal para las mujeres. Las mujeres de carrera administrativa presentan una serie de barreras que les impiden desempeñarse en cargos directivos de la misma forma que sus homónimos, en las organizaciones sin importar de que tipo sean se tiene que realizar un trabajo arduo para evitar que las habilidades, y capacidades de las mujeres no sean valoradas o remuneradas de la misma manera que los hombres.
New insights into the Weddell Sea ecosystem applying a quantitative network approach
Authors: Marina Tomás I. , Saravia Leonardo A. , Kortsch Susanne
Published: January 2023

Abstract. Network approaches can shed light on the structure and stability of complex marine communities. In recent years, such approaches have been successfully applied to study polar ecosystems, improving our knowledge on how they might respond to ongoing environmental changes. The Weddell Sea is one of the most studied marine ecosystems outside the Antarctic Peninsula in the Southern Ocean. Yet, few studies consider the known complexity of the Weddell Sea food web, which in its current form comprises 490 species and 16041 predator-prey interactions. Here we analysed the Weddell Sea food web, focusing on the species and trophic interactions that underpin ecosystem structure and stability. We estimated the strength for each interaction in the food web, characterised species position in the food web using unweighted and weighted food web properties, and analysed species’ roles with respect to the stability of the food web. We found that the distribution of the interaction strength (IS) at the food web level is asymmetric, with many weak interactions and few strong ones. We detected a positive relationship between species mean IS and two unweighted properties (i.e., trophic level and the total number of interactions). We also found that only a few species possess key positions in terms of food web stability. These species are characterised by high mean IS, mid to high trophic level, relatively high number of interactions, and mid to low trophic similarity. In this study, we integrated unweighted and weighted food web information, enabling a more complete assessment of the ecosystem structure and function of the Weddell Sea food web. Our results provide new insights, which are important for the development of effective policies and management strategies, particularly given the ongoing initiative to implement a Marine Protected Area (MPA) in the Weddell Sea.

Published: January 2023

Abstract. In this paper, the first steps towards integrating a mass sensing system
into an existing miniaturized ceramic DSC (differential scanning
calorimetry) chip are presented. A vibration setup is developed based on the mass-dependent change in frequency of the DSC chip as an oscillating
cantilever. A simulation model reveals that the resolution of the
measurement can be improved by reducing the chip thickness. In this study,
different measurement methods (acoustic, optical, and piezoresistive) are
investigated. Three complete measurement systems are set up and evaluated
with regard to their integration in the DSC chip. All presented measurement
methods show promising results and already allow mass measurements with a
resolution of 100 µg.

Authors: Gaur Parul , Gaur Deepak , Tomar Aruna
Published: January 2023

Ultra wideband radio over optical fiber (UROOF) technique enables the transmission of ultra wideband (UWB) radio signals over optical fibers by superimposing the UWB radio frequency signals of several gigahertz's on the optical continuous-wave carrier. UWB signals are characterized by an extremely large bandwidth. UWB frequency bands belong to 3.1-10.6 GHz according to the spectral mask defined by the Federal Communications Commission. This paper examines how by using multi-band orthogonal frequency division multiplexing (MB-OFDM) technique UWB transmission can be extended up to 60 GHz. MB-OFDM divides the spectrum into six band groups and 14 non-overlapping sub bands of 528 MHz bandwidth each. Each OFDM symbol is composed of 128 orthogonal subcarriers spaced 4.125 MHz apart.

It was also observed that performance of above six systems using R600 and R152a nearly matching same values under the accuracy of 5% can be used in the above system .But difficulties using R600, R290 and R600a have flammable problems therefore safety measures are required using these refrigerants, therefore R134a refrigerant is recommended for practical and commercial applications although it has slightly less thermal performance than R152a which is not widely used refrigerant for domestic and industrial applications.
Modeling and Simulation of a 3-wheel Rear Axle
Authors: Chandan Swet , Kumar Aman , Luthra Madhav
Published: January 2023

All commercial vehicles have some type of axle shaft-differential assembly incorporated into the driveline. Rear wheel drive is a common form of engine-transmission layout used in automobiles. Rear wheel drive means the power from the engine and the transmission goes to the rear wheels. In operation, axle shafts are generally subjected to torsion stress and bending stress due to self-weight or weights of components or possible misalignment between journal bearings. Thus, these rotating components are susceptible to fatigue by the nature of their operation and the fatigue failures are generally of the torsion, rotating-bending, and reversed (two-way) bending type.
The Objective behind creation of this project is that Indian roads which have bad riding quality, poor geometrics, and insufficient pavement thickness:all these factors affect the life of axle and also not much research has been done in this area.There is strong need of this project because in a three wheeler there are many things which can be improved or prevented like:-
1. Breaking/failure of rear wheel axle. 2. We can increase the efficiency of axle. 3. We can use that material in axle which is less costly and has longer life. 4. We can improve on the axial design. 5. Not much research has been done. Different tests were performed on the existing axle. Then all the readings and results were taken into account and different materials were selected and calculations were done on them regarding different diameters. At last the best material was selected and was fabricated; also we have calculated the amount of fuel saved from this project

Published: January 2023

This paper deals with study using soft computing techniques, namely Artificial Neural Networks ANN, in predicting the surface roughness in turning process. Some of machining variables that have a major impact on the surface roughness in turning process such as spindle speed, feed rate and depth of cut were considered as inputs and surface roughness as output. Surface roughness, is the most specified customer requirements in a machining process. For efficient use of machine tools, optimum cutting parameters (speed, feed and depth of cut) are required. Therefore it is necessary to find a suitable optimization method which can find optimum values of cutting parameters for minimizing surface roughness. The turning process parameter optimization is highly constrained and nonlinear. In present work, machining process was carried out on Aluminium (6061) material and surface roughness was measured using Surface Roughness Tester. To predict the surface roughness, neural network model was designed through Multilayer Pereceptron network for the data obtained. The predicted surface roughness values computed from ANN, are compared with experimental data and the results obtained, conclude that neural network model is reliable and accurate for solving the cutting parameter optimization.

Protection of Power System Using Sequential Tripping
Authors: Kapoor Mansi , Singh Jaikaran , Sharma Arvind Kumar , Agarwal Mayur
Published: January 2023

This paper describes a Sequential Tripping Strategy used in an electrical power system to combat situations in which protection relays have maloperated or information is missing. This is an innovative back-up protection scheme designed to prevent the occurrence of widespread blackouts. It evaluates the certainty that transmission lines are likely to be affected by the fault and uses a Sequential Tripping Strategy to isolate the fault if a firm decision is not available due to maloperated relays and/or missing information. The mode of analysis and the Sequential Tripping Strategy ensures that the fault can be cleared at minimum risk to the network.
In applications like power stations and continuous process control plants, a protection system is used to trip faulty systems to prevent damages and ensure the overall safety of the personnel and machinery. But this often results in multiple or cascade tripping of a number of subunits. Looking at all the tripped units doesn't reveal the cause of failure. It is therefore very important to determine the sequence of events that have occurred in order to exactly trace out the cause of failure and revive the system with minimal loss of time.
Untouchable and Coolie: The Soul of Social Realism
Authors: Agarwal Anupam , Shukla Sonal
Published: January 2023

Mulk Raj Anand is very well- known as an Indian novelist, distinguished writer, reformer, art critic, editor, journalist, a short story writer and political activist. He opened a new section of writers of fiction along with Raja Rao and R. K. Narayan and produced a great deal of English literature and his mastery in the realistic and sympathetic portrayal of the exploited class of Indian society marks his genius as a socially committed novelist. That‟s why he is not only known as India‟s Charles dickens but also considered the messiah of the have-nots, unloved, down trodden and unwanted. The exploitation of the downtrodden in Indian society made him focus his attention on their miserable and pathetic condition and formed the major theme of his works. His writings reflect his urgent social concern, preoccupations and the social impulse and made the reader to be immediately aware of the exploitation faced by the downtrodden through the heart throbbing description of their wretched state. Painted with the colors of social realism Mulk Raj Anand‟s two novels Untouchable and Coolie reflect the hard core reality of the Indian society of early decades of twentieth century.. Written with a purpose both these novels condemn the modern capitalistic Indian society and feudal system for the shameless and tragic exploitation of the poor and underdog as there is nothing but a true, real and bitter reflection of the society in both the novels dealing with a similar central theme of social exploitation, the exploitation of the downtrodden and the under-privileged because of the curse of untouchability, poverty, hunger, child labour, social governance, social set up of society, customs, religious belief, prejudices and the suffering of the Indian masses by the forces of capitalism, industrialism and colonialism. The present paper shows the true colours of social realism in Untouchable and Coolie; the epic like novels of M. K. Anand to strike a cord in the hearts of the consciententious Indians through a beautiful and real to life portrayal of the exploited masses of Indian society.

Authors: Kamal Vishav , Mishra R. S.
Published: January 2023

Computer simulation of porous Trombe wall has been carried out for providing comfortable thermal environment. During sunshine hours excess heat is stored within the porous absorber and there is stratification in the porous layer. For two different porous materials viz. marble and quartzite, explicit expressions for heat flux and thermal efficiency of the porous system have been developed. The experimental results have been validated with numerical computations using the developed model. It has been observed that Trombe wall contributes 20% to 30% of the total heating of the buildings depending upon type of material. The average thermal efficiency of the wall has been found to be 29.09% for brick wall, 37.27% for concrete wall, 45.35% for marble wall and 57.2% for quartzite wall respectively.. The results from presented mathematical model would help the designers of passive solar systems to use this model for selecting optimal constructive parameters of the non-porous Trombe wall.

Authors: Ahmad Sofia
Published: January 2023

Landslides are the most far-flung natural hazards, causing loss of thousands of lives and billions of dollars annually worldwide. Particularly in the hilly regions has led to the necessity of in-depth study and research in the field of landslide hazard zonation. Despite many technical papers being considered in this area of study, there is no particular standard method available for evaluating and predicting the pattern of landslides. Different researchers come up with different methods for landslide hazard assessment, due to complexity involved in the landslide triggering mechanisms. As the triggering factors of the landslides are not uniform and the nature of the earth is not same, it is very often confusing to identify appropriate method to apply. This paper deals with the compilation of various landslide hazard assessment methods with adequate contextual information. A critical review is presented on each of these methods, highlighting their limitations and suitability of application.

Published: January 2023

With the increasing fears of the impacts of the high penetration rates of Photovoltaic (PV) systems, a technical study about their effects on the power quality of the utility grid is required. Since such study requires a complete modeling of the PV system in an electromagnetic transient software environment, for that MATLAB was chosen. This paper investigates a grid-tied PV system that is prepared in MATLAB. The model consists of PV array, DC link capacitor, DC-DC boost converter, single phase hysteresis current control inverter, AC inductive filter and a utility grid equivalent model. The paper starts with choosing MATLAB as the simulation environment and then by investigating the tasks of the different blocks of the grid-tied PV system model. It has also undertaken the various effects of variable atmospheric conditions (irradiation and temperature) on the performance of the different components in the model. DC-DC converter and inverter in this model use PWM and SPWM switching techniques, respectively. Finally, total harmonic distortion analysis on the inverter output current at PCC was applied and the values obtained were compared with the limits specified by the regulating standards such as IEEE Std 519-1992.This paper presents an overview of the matrix converter and its modulation techniques with application. Matrix converter is one of the most interesting members of power converter family; provide direct AC-AC conversion.

Friction Stir Processing of Aluminum alloys for Defense Applications
Authors: Arulmoni V. Jeganathan , Mishra R. K.
Published: January 2023

Friction stir processing (FSP) is a surface modifying Technique, which was developed, based on the basic principles of friction stir welding (FSW), but FSP is used to modify the local microstructure and does not join metals together..A rotating tool with pin and shoulder is inserted into a single piece of material and traversed along the desired path to cover the region of interest. Friction between the shoulder and workpiece results in localized heating which raises the temperature of the material to the range where it is plastically deformed. During this process, the severe plastic deformation and thermal exposure of material, results in a significant evolution in the local microstructure. FSP has been successfully used for formation of nanograin, increase the surface hardness and also enhances the wear resistance, tensile strength and fatigue strength of the material. This review paper, the current scenario and development of FSP of various materials mainly (a) formation of nanograins, microstructure and mechanical properties. (b) Effect of FSP/W process parameters.

Published: January 2023

The study describes the thermodynamic methodology for the performance evaluation of alternative regeneration gas turbine cycle with twin shaft system. The effects of pressure ratio, turbine inlet temperature, inlet air temperature and regenerative effectiveness used in the thermodynamic analysis of alternative regeneration gas turbine cycle with twin shaft system on thermal efficiency, specific work output and specific fuel consumption of the cycle have been investigated. It is observed that thermal efficiency of gas turbine alternate regeneration system increases with pressure ratio with increase in turbine inlet temperature and specific work output increases with increase in turbine inlet temperature but lower than conventional regeneration system. The thermal efficiency and specific work output of the cycle increases with decrease in inlet air temperature. The specific fuel consumption decreases with increase in both pressure ratio and turbine inlet temperature and with decrease in inlet air temperature. This system is very attractive at high turbine inlet temperature of 1500 0C and above.

Published: January 2023

Honing is an abrasive machining process that is the "best kept secret" at many leading gun barrel producers, whether the end product is a fine sniper rifle, a police service pistol or an aircraft cannon. Simply put, honing produces a more accurate barrel a better overall product for lower cost.The Aim of the research is to design and manufacturing a honing tool for a drilling machine that can give require surface finish and dimensional accuracy as given by a honing machine and since we know that honing machine are very costly and every manufacturer cannot afford it on the other hand drilling machine are cheap as compare to honing machine and are available even in small workshops so our basic aim to reduce the cost of surface finish is fulfilled and we are succeed in getting the same surface finish and dimensional accuracy obtain by a honing machine. The contents of this report include design, manufacturing and working of honing tool and their study as well. It is well known that a good honing machine is very costly and all manufacturers cannot afford it. We have also seen that hand honing is resorted to by road side repairers and their cylinders lack in the requirements of circularity/cylindricity smoothness. The design is simple in the sense that any manufacture having a drilling machine and simple manufacturing facilities can manufacture on his own and achieve the necessary technical requirements of smoothness of surface as well as requirements of close tolerance on circularity and cylindricity.We use our tool in a drilling machine, because these are very cheap as compared to honing machines and are also available in every mechanical workshop. So our main aim is to reduce the cost of honing and at the same time achieve the desired accuracy as given by the honing machine i. e, in the range of 0.005 microns.

Authors: Srivastava Ashish , Dixit Amit Rai , Tiwari Sandeep
Published: January 2023

The trend towards the use of composites is increasing rapidly in the ongoing scenario and is likely to increase more rapidly in the future. Nowadays aluminium and its alloy based composites are gaining importance in the upcoming fields of engineering. Aluminium metal matrix composite (AMMC) possess superior strength, hardness, corrosion resistance, fatigue and creep resistance in addition to low weight advantage of aluminium. Aluminium based composites (AMMC) are widely used in aerospace and automotive industries due to high strength to wear ratio. Mechanical Components due to insufficient strength fails under various types of loading. Modern mechanical components require advance properties, the material available in pure form do not possess the required strength, hardness, corrosion resistance etc. A Composite is formed by combination of two or more physically and chemically distinct substances and is fabricated to enhance the characteristics of base metal. The material is then characterized by the different types of analysis like tensile, impact, hardness, along with thermal analysis such as XRD and DTA. Metal matrix composite (MMC) are formed when the base metal is metal and reinforcement takes place in the form of powder, particles, fibers and whiskers. Reinforcements in the metal matrix composite may be a metal or other material which may be ceramic or any other organic compound. Metal matrix composites (MMC) possess significantly enhanced properties which improve the functioning as well as service life of the various mechanical components. This paper is aimed to review the theory, experiments and methodology to fabricate aluminium metal matrix composites (AMMC) and also the characterization of fabricated material.
