Bit Error Rate Performance Measurement of Wireless MIMO System Based on FPGA
Authors: S. Aravind Kumar , S. Karthikeyan
Published: January 2023

To measure the bit error rate (BER) performance validation of digital baseband communication systems on a field-programmable gate array (FPGA). The proposed BER tester (BERT) integrates fundamental baseband signal processing modules of a typical wireless communication system along with a realistic fading channel simulator and an accurate Gaussian noise generator onto a single FPGA to provide an accelerated and repeatable test environment in a laboratory setting. Using a developed graphical user interface, the error rate performance of single- and multiple-antenna systems over a wide range of parameters can be rapidly evaluated. The FPGA-based BERT should reduce the need for time-consuming software-based simulations, hence increasing the productivity. This FPGA-based solution is significantly more cost effective than conventional performance measurements made using expensive commercially available test equipment and channel simulators.
Design of Low Efficiency DSP Architecture for Wireless Sensor Networks
Authors: A. Nirmal Raj , S. Edit Pelinda
Published: January 2023

Radio communication exhibits the highest energy consumption in wireless sensor nodes. Given their limited energy supply from batteries or scavenging, these nodes must trade data communication for on-the-node computation. Currently, they are designed around off-the-shelf low-power microcontrollers. But by employing a more appropriate processing element, the energy consumption can be significantly reduced. This paper describes the design and implementation of the newly proposed folded-tree architecture for on-the-node data processing in wireless sensor networks, using parallel prefix operations and data locality in hardware. Measurements of the silicon implementation show an improvement of 10–20× in terms of energy as compared to traditional modern micro-controllers found in sensor nodes.

Authors: Shukla H. S. , Verma Ravi
Published: January 2023

In this paper, a calculation for dividing skin districts in shading pictures utilizing shading and edge data is exhibited. Skin hued areas are initially recognized utilizing a Bayesian model of the human skin shading. These areas are further divided into skin district competitors that fulfill the homogeneity property of the human skin. We demonstrate that Bayesian skin shading model beats numerous different models, for example, the piece-wise straight models, Gaussian models and model in light of multilayer discernments. Test results show that the proposed division calculation decreases false location brought about by foundation pixels having skin hues, and all the more altogether it is fit for isolating genuine skin districts from dishonestly recognized areas.

Effect of electromagnetic field and mechanical milling in the synthesis of metal matrix Nano composite
Authors: Kumar Kapil , Sultan Samar
Published: January 2023

Ceramic nanometric SiC particles (n-SiCp) were reinforced in 7075 aluminium matrix to synthesize the metal matrix nano composites (MMNCs). The inclusion as well as uniform distribution of nano particles in aluminium matrix is a great challenge. To accomplish this, a new hybrid stir casting technique was used to fabricate the MMNCs. The uniform distribution of the reinforcement depends on good wettability of reinforcement with the metal matrix. Hence, to improve the wettability, 1 wt % micro Mg particles were mechanically milled with two different additions of n-SiCp with weight fractions 1% and 1.5 % and injected into the matrix melt with the assistance of argon gas. As-casted materials were peak aged for 12 hours at 135º C. Tensile tests, low speed impact test and hardness tests were used to investigate mechanical behaviour and found that composite reinforced with 1% SiC exhibited better mechanical properties. The mechanical properties of nano-composites are characterized by employing optical microscopy, scanning electron microscopy and X-ray diffractometer. This method remarkably facilitated a uniform dispersion of nano-SiC within the aluminium matrix as well as a refinement of grain size.
El genitivo en -īus de la flexión pronominal latina
Authors: Suárez-Martínez Pedro Manuel
Published: January 2023

El genitivo de los tradicionalmente llamados pronombres presenta una extraña forma en -īus, con una -ī- que parece resistir a la abreviación, al menos en latín arcaico, a pesar de encontrarse ante vocal. Tal anomalía se ha tratado de explicar mediante la formulación de diversas teorías, aunque casi siempre de forma insatisfactoria. De todas ellas, nos parece que la ofrecida por A. Tovar, la de que se trataría de una antigua forma de genitivo en -ī- hipercaracterizada con la desinencia de genitivo -os, nos sigue pareciendo la más acertada, aunque este autor señale que su punto débil es que no puede «alegar ninguna prueba concluyente para explicar la conservación de la -ī- intervocálica».
Por nuestra parte, partiendo de esta última teoría, intentaremos ofrecer paralelos de conservación de la -ī- intervocálica en latín, que no acierta a alegar Tovar, y explicar los distintos tratamientos de esa -ī-, pues no en todas las formas consideradas ni en todas las etapas del latín se comporta del mismo modo.
Alliteratio, onomatopoeia and imitative harmony: differentiation and conceptual frontiers
Authors: Salvador-Gimeno Marina
Published: January 2023

Nuestro objetivo en las siguientes páginas es aclarar la confusión existente entre los conceptos de aliteración, onomatopeya y armonía imitativa, que actualmente se utilizan sin rigor. De hecho, las diferencias entre la onomatopeya y la armonía imitativa ahora se han atenuado (y desdibujado). Han sido reducidos a la categoría de función, habiéndose convertido en manifestaciones específicas de la aliteración, recurso al que se le ha atribuido erróneamente una finalidad icónico/expresiva.
La sinonimia incorrecta entre aliteración, onomatopeya y armonía imitativa también se refleja en la práctica, donde es posible observar el uso indiscriminado de los tres términos. Un factor importante a tener en cuenta en la identificación incorrecta de estas técnicas es la subjetividad de los estudiosos, quienes, a nuestro juicio, tienden a atribuir un valor icónico/expresivo a las repeticiones sonoras puramente rítmicas. Ante esto, hacemos una llamada al rigor y objetividad de los estudiosos para evitar confusiones de este tipo

Microfacies of the Emen Formation (Lovetch Urgonian Group, Lower Cretaceous, Fore-Balkan)
Authors: Minkovska Vyara
Published: January 2023

Detailed microfacial analysis of three sections of the Emen Formation (Lovech Urgonian Group, Central Fore-Balkan) revealed thirteen different facies types corresponding to distinct sedimentary environments on the carbonate platform, such as basin, external and internal platform. Among these, facies types of the internal platform seem to be the most common. The section near the "Al. Stamboliyski" dam differs from the one near Emen village and from a drillhole section ("Preobrazhenski manastir") because of the diverse compositional structures of the limestones and the large number of shaly-terrigeneous intercalations. The upper part of the "Al. Stamboliyski" section is composed of mixed muddy-terrigeneous facies types. These characteristics are interpreted as the result of different settings on the carbonate platform in terms of paleogeography, reflecting also changing of the depositional conditions through time. This study, based on the quantified curves of vertical evolution of microfacies associations, provides a key to the temporal and spatial evolution of sedimentation during the deposition of the Emen Formation. The facies types described in this study can be directly compared to those recently defined in the Lower Cretaceous carbonate platform of Southern France.
Neotectonic and geomorphological characteristics of the western part of the Aydemir Lowland, Silistra District
Authors: Angelova Dora
Published: January 2023

Neogene, Quaternary and recent characteristics of the western part of the Aydemir lowland are presented in this paper. The "Srebarna" swamp is situated in this region being a biosphere reserve under UNESCO protection as well as their results-relief and substrate. There are some geodynamic development differences of various blocks of the investigated region found on the basis of correlative deposition age determinations. A paleoseismodislocation named "Srebarna" bound to the Pleistocene-Holocene boundary and aged 10500 ± 250 yr. has been found for the first time. It has a length 2750 m, a width varying from 750 up to 1000 m and a vertical amplitude – 20 m. The paleoseismodislocation is situated at a tectonic junction of a first-rank longitudinal tectonic zone and a third-rank meridional tectonic zone. It marks the epicentral zone of the earthquake. A block has been broken off as a result of one-act seismic event (intensity of 8-9 degree and supposed depth of 30-60 km). As a result of this event, the Srebarna and Kalnezhka River mouths have been naturally embanked by the gravitationally subsided block. It has been a natural barrage for the rivers' waters. The block has caused water baffling to its base, and thus their loss in the karstic underseams. The investigations presented in this paper are of practical importance due to the value of the biosphere reserve and the respective natural-geomorphological phenomenon.

Published: January 2023

Administrative activity, in addition to the classic ones, includes more and more non-authoritative activities, and their effectiveness largely depends on the organization of the administration, distributed at different levels of territorial and political organization. The constitutional framework implies that the establishment of the system in various areas of the economy is in the competence of the state, while the autonomous provinces and local self-government units have certain competencies. Legal identification and standardization of administrative affairs and tasks in the field of tourism should be such that it does not endanger the freedom of private initiative, but do provide protection of the public interest. The analysis of the constitutional and legal framework includes the system of distribution of competencies in the field of tourism, the nature of administrative affairs and organizational forms of their implementation in the Republic of Serbia and a comparative review.

Authors: Singh Balvender , Krishan Bishnoi Shree
Published: January 2023

In this work adaptive fuzzy- PID (ANFIS-PID) controller is presented for frequency and tie-line regulation of multi-area interconnected power systems (IPS). The proposed controller has the properties of both neural network and fuzzy logic. A novel four area power system comprises two reheat turbines (area1 and area2), one hydropower plant (area 3) with the hydraulic governor and one wind plant (area 4) with a pitch actuator. This hybrid interconnected power system model has been built in MATLAB/ Simulink version 2020(a) and the proposed controller is employed with the same design of ANFIS model in all areas. Further, the performance of power system model is presented with the suggested controller. The step load change is considered in each area. An HVDC lines are considered in each area to improve the performance of the proposed model. Further, a fair comparison is made for the conventional PID and Fuzzy-PID controllers. The designed controller performs best compared to the other compared controller for tie-line power and frequency regulation in all four areas of the IPS. The dynamic response of the proposed model improves with AC/DC line as compared to AC line. The sensitivity analysis with change in plant parameters, step load perturbation (SLP) and random load change is also being applied to check the robustness of the controller.
Capítulo 3. La polarización discursiva como estrategia de comunicación en las cuentas de líderes y partidos políticos en Twitter
Authors: Marín-Albaladejo Juan Antonio
Published: January 2023

Los discursos proyectados en medios sociales por los líderes y las cuentas vinculadas a sus partidos pueden contribuir al crecimiento de la crispación en el debate público y la polarización afectiva entre grupos con posturas políticas opuestas. El despliegue constante de una retórica maniquea que fomenta las divisiones sociales e incide en los ataques contra los adversarios se asocia a menudo con las estrategias que permiten a determinados actores políticos y mediáticos captar una mayor atención en la conversación digital y reforzar identidades tribales entre sus seguidores. En este capítulo se exponen una serie de mecanismos discursivos polarizadores con los que diversas formaciones políticas y sus dirigentes trazan antagonismos excluyentes en mensajes publicados en Twitter. No obstante, también se explica que estos elementos suelen ser característicos del estilo comunicativo de los populismos y las opciones situadas en los extremos ideológicos y, por consiguiente, tienden a hallarse sobre todo en los perfiles de este tipo de partidos y figuras públicas. La propia dinámica de funcionamiento de algunas herramientas digitales y el éxito de campañas centradas en la estigmatización del oponente hacen que resulte difícil atajar el protagonismo de los debates emocionales y la difusión de encuadres polarizantes en las redes y la agenda mediática. De modo que para comprender mejor el crecimiento de la polarización es preciso poner el foco en los incentivos que tienen determinados agentes para la utilización continua de discursos inflamantes, en los que abunda un lenguaje provocador que fomenta la hostilidad hacia los rivales políticos.

Prólogo
Authors: Waisbord Silvio
Published: January 2023

Este libro ofrece un panorama actualizado y minucioso sobre cuestiones centrales en el estudio de la comunicación política en tiempos de polarización. Considerando la limitada literatura en castellano sobre el tema, éste es un valioso aporte sobre problemas centrales que merecen atención e investigación. El punto de partida son los desafíos de la polarización, especialmente de la polarización afectiva, para la democracia y la dificultad de entrever soluciones factibles. Puesto que el conflicto es intrínseco a la política, la democracia promete la existencia de mecanismos efectivos para expresar, resolver y trascender conflictos. Del antagonismo puro, sin mediaciones ni resoluciones, no se construye un orden democrático estable, sino que se alimentan tensiones constantes que amenazan la calidad de la política. Esto es así particularmente cuando las identidades políticas están ancladas en la exclusión del otro, en intentar expugnar espacios de oposición e instalar mecanismos para suprimir la disidencia. El discurso del odio opera como facilitador de tales identidades que, lejos de ser hechos democráticos de expresión y reafirmación de la diferencia, se convierten en impulsores de la exclusión política y social. Además, sienta las bases para proyectos autoritarios que apunten a erigir identidades parciales como identidades totalizantes.

Increasing safety in residential construction through a simplified earthquake- and typhoon-resistant guidelines
Authors: Ballesteros Linnel Marie S. , Ourang Shiva , Pazdon Jennifer , Kuffel Karin
Published: January 2023

This paper presents the engineering basis for a document, Residential Design and Construction Guidelines (hereafter, Guidelines). The Guidelines is developed by the engineers of Build Change and its partners based on their technical reconnaissance after the 2013 earthquake in Bohol on October 15, 2013, and Typhoon Haiyan on November 8, 2013. The Guidelines are centered on the observations of typical residential construction and damage in these areas and the requirements of the 2010 National Structural Code of the Philippines. The Guidelines provide illustrated and simple instructions on residential construction, making them accessible to homeowners and local builders. The Guidelines are designed for disaster-resistant, permanent low-rise housing construction, endorsed by the Department of Public Works and Highways of the Philippines (in March 2016). Increasing understanding and application of the Guidelines in residential construction in earthquake- and typhoon-prone areas will increase the structural safety of houses and the country's resiliency.

Цель исследования: изучить влияние приверженности к медикаментозной терапии на показатели физической активности, оцениваемой по тесту шестиминутной ходьбы, у пациентов, перенесших инфаркт миокарда.

Материал и методы. Общеклинические методы обследования, анкетирование пациентов с помощью опросника Мориски – Грина (MMAS-4), выполнение теста шестиминутной ходьбы, статистические методы анализа.

Результаты. По результатам оценки приверженности к медикаментозной терапии 28 пациентов (62,2 %) отнесены к категории высокоприверженных (уровень по опроснику Мориски – Грина 4 балла из 4), а 17 пациентов (37,8 %) были низкоприверженны (уровень менее 4 баллов по опроснику Мориски – Грина). Обнаружена положительная корреляционная связь между уровнем приверженности к медикаментозной терапии и пройденной дистанцией при тесте шестиминутной ходьбы у пациентов, перенесших инфаркт миокарда (r = 0,345; p = 0,020).

Выводы. Приверженность к назначенной медикаментозной терапии прямо влияет на показатели физической активности пациентов, перенесших инфаркт миокарда, оцениваемые по величине пройденной дистанции во время теста шестиминутной ходьбы.

Δ-wavy probability distributions and Potts model
Authors:   Romanian Academy ", Păun Udrea ,   Gheorghe Mihoc - Caius Iacob",   Institute of Mathematical Statistics and Applied Mathematics, Romania
Published: January 2023

We define the wavy probability distributions on a subset and Δ-wavy probability distributions - two generalizations of the wavy probability distributions. A classification on the Δ-waviness is given. For the Δ-wavy probability distributions having normalization constant, we give a formula for this constant, to compute this constant. We show that the Potts model is a Δ-wavy probability distribution, where Δ is a partition which will be specified. For the normalization constant of Potts model, we give formulas and bounds. As to the formulas for this constant, we give two general formulas, one of them is simple while the other is more complicated, and based on independent sets, a formula for the Potts model on connected separable graphs - closed-form expressions are then obtained in several cases -, and a formula for the Potts model on graphs with a vertex of degree 2 - a recurrence relation is then obtained for the normalization constant of Potts model on Cn; the cycle graph with n vertices; the normalization constant of Ising model on Cn is computed using this relation. As to the bounds for the normalization constant, we present two ways to obtain such bounds; we illustrate these ways giving a general lower bound, and a lower bound and an upper one when the model is the Potts model on Gn,n, the square grid graph, n = 6k, k ≥ 1 - two upper bounds for the free energy per site of this model are then obtained, one of them being in the limit. A sampling method for the Δ-wavy probability distributions is given and, as a result, a sampling method for the Potts is given. This method - that for the Potts model too - has two steps, Step 1 and Step 2, when |Δ| > 1 and one step, Step 2 only, when |Δ| = 1. For the Potts model, Step 1 is, in general, difficult. As to Step 2, for the Potts model too, using the Gibbs sampler in a generalized sense, we obtain an exact (not approximate) sampling method having p + 1 steps (p + 1 substeps of Step 2), where p = |I|; I is an independent set, best, a maximum independent set, best, a maximum independent set - for the Potts model on Gn1,n2,…,nd , the d-dimensional grid graph, d ≥ 1, n1, n2,…, nd ≥ 1, n1n2·…·nd ≥ 2; we obtain an exact sampling method for half or half+1 vertices.

The aim of the present investigation was determine the butterfly diversity in a village Banihari, West Bengal, India and calculate the diversity indices. Pollard transect line method with minor changes was adopted for study. Survey was done at early morning with monthly interval. Butterflies were photographed with digital camera. Number of butterflies within the transect line were counted and then calculated the diversity indices with PAST 3.0 software. A total 48 butterfly species under four families were recorded during the study period. Most dominant family was Nymphalidae then followed by Pieridae, Lycaenidae and Papilionidae. Number of taxa, Shannon diversity index and Margalef species richness index were maximum at site1 and minimum at site 4. Most common butterflies were Common Mormon, Psyche, Blue Tiger, Plain Tiger, Striped Tiger, Grey Pansy, Small branded swift and Angled Castor. Moderate numbers of Butterflywere reported at the study site. Butterfly diversity depends on availability of host plants. Butterfly diversity decreased day by day due to many anthropogenic activities such as habitat loss, loss of host plant and use of pesticides.

Maize is one of the vital crops after rice and wheat in India and is a widely produced cereal. Maize contributes only 2.4 percent of total world production. Maize occupied 9.21 Mha, with a production of 25.82 MT in India. The average yield per hectare during 2018-19 was 2804 kg per hectare. Maize is being used in numerous sectors and is consumed mainly in poultry in India. The demand for maize in the developing world would double and to meet the demand, the production must be increased. The small-scale harvesters which can be affordable by Indian farmers are to be developed to make harvesting operations easier. The proposed machine can accomplish three operations at a time: cutting the maize stalk, removing cobs from the stalk, and collecting removed cobs from the plant. The machine will be of great use for small-scale farmers in many ways.

Good quality feed resources are very important component to achieve the production potential from livestock business. Supplementation of protein rich fodder tree leaves or its leaf meal could be a potential alternative for increasing the quality of livestock diet. A study was conducted to assess Moringa foliage plantation with respect to leaves and wood leaves and wood production per unit area to quantify precise biomass production. The relationship between plant base diameter to leaf biomass and wood mass yield were established and observed high correlation coefficients (R2 ) ranges from 0.80 to 0.87. Mean fodder leaves yield of 227q/ha, woodmass yield of 984q /ha with leaf stem ratio of 18.8:81.2 were observed on fresh harvesting basis. Dried leaf and wood mass production were recorded 66q/ha and 659 q/ha, respectively. The crude protein yield from Moringa leaves was assessed as 12.9 q on dry matter basis from one hectare Moringa field. A process methodology has also been developed for the preparation of Moringa leaf meal.

A field experiment was undertaken at Bidi Tobacco Research Station, Anand Agricultural University, Anand for three consecutive years viz., 2017-18 to 2019-20 to study influence of nitrogen and topping levels on yield and quality of bidi tobacco hybrid varieties. The experiment was laid out in factorial randomized block design assigning two hybrid varieties, i.e. MRGTH 1 and GABTH 2, three nitrogen levels i.e. 140, 180 and 220 kg/ha and three topping levels, i.e. 18, 21 and 24 leaf stages with three replications. The data pooled over three years revealed that tobacco variety GABTH 2 recorded significantly the highest tobacco cured leaf yield (3700 kg/ha) with maximum net realization of `117433/ha and BCR value 3.06. Both the upper levels of 180 and 220 kg nitrogen/ha, being at par with each other produced significantly higher cured leaf yield of 3388 and 3407 kg/ha, respectively as compared to lower level of 140 kg nitrogen/ha. Topping levels were failed to exert their significant effect on tobacco cured leaf yield. Application of nitrogen @ 180 kg/ha gave maximum net realization of `102741/ha and BCR value of 2.81 as compared to lower level of 140 kg/ha whereas, tobacco crop topped at 21 leaves gave maximum net income of `105898/ha with 2.86 BCR. Tobacco varieties and nitrogen as well as topping levels had non-significant effect on leaf chemical constituents i.e. nicotine, reducing sugar and chloride contents. Wherein, only nicotine content was significantly changed due to tobacco varieties and different topping levels. Tobacco variety MRGTH 1 and topping level at 18 leaves gave significantly the highest nicotine content compared to others.
