FPGA based Identification of Frequency and Phase Modulated Signals by Time Domain Digital Techniques for ELINT Systems
Authors: Niranjan R.K. , Rama Rao C.B. , Singh A.K.
Published: February 2021

In this paper, a decision tree algorithm based on time-domain digital technique is developed for the identification and classification of diverse radar intra-pulse modulated signals for the electronic intelligence system in real-time. This includes linear frequency modulation, non-linear frequency modulation, stepped frequency modulation and bi-phase modulation. The received signal is digitised and the instantaneous phase and high accuracy instantaneous frequency are estimated. The instantaneous amplitude is also estimated to get the start and stop of the pulse. Instantaneous parameters are estimated using a moving autocorrelation technique. The proposed algorithm is employed on the instantaneous frequency and the modulation is identified. The modulation type and modulation parameter are important for unique radar identification when similar radars are operating in a dense environment. Simulations are carried out at various SNR conditions and results are presented. The model for algorithm is developed using a system generator and implemented in FPGA. These results are compared when the proposed algorithm is used with the existing digital in-phase and quadrature-phase (DIQ) technique of instantaneous frequency and amplitude estimation.
Choice of Interceptor Aerodynamic Lifting Surface Location based on Autopilot Design Considerations
Authors: Sankar Ram B. , Tiwari P. K. , Bandyopadhyay B. , Arya H.
Published: February 2021

Interceptors operate at wide range of operating conditions in terms of Mach number, altitude and angle of attack. The aerodynamic design caters for such wide operating envelope by appropriate sizing of lifting and control surfaces for meeting the normal acceleration capability requirements. The wide range of operating conditions leads to an inevitable spread in center of pressure location and hence spread in static stability. The performance of control design is a strong function of the aerodynamic static stability. The total operating envelope can be bifurcated into statically stable and unstable zones and the aerodynamic lifting surface location can be used as a control parameter to identify the neutral stability point. During the homing phase lesser static stability is desirable for good speed of response, hence the lifting surface location needs to be chosen based on the capability of control to handle instability. This paper analyses the limitations of autopilot design for the control of an unstable interceptor and brings out a method to identify the optimum aerodynamic lifting surface location for efficiently managing static margin while satisfying the control limitations and homing phase performance. This provides an input on the most appropriate lifting surface location to the aerodynamic designer during the initial CFD based aerodynamic characterisation stage itself, before commencing the rigorous wind tunnel based characterisation.

Published: February 2021

The detection of underwater objects is one of the most critical technologies, and there have been constant efforts for developing sophisticated sonar systems in naval warfare. Against such efforts, the countermeasure of hiding underwater vehicles, equipment and weapons is another technological challenge. One of the effective countermeasures against sonic detection for the submarines and other underwater objects, such as naval mines, is to employ composite/hybrid materials to prevent ease of detection. Geometrical forms, shapes and layers, along with the tuning of the acoustical impedance, lead to a considerable decrease of the sonar signals via absorption of the sonic waves. In this study, an original and novel design of multi-layered composite/hybrid structure was developed and underwater acoustic testing procedures of reflection, transmission and scattering were applied in 80 kHz100 kHz frequency range. The findings obtained in this study showed that the multi-layered composite/hybrid materials with porous structure possess much lower values in millivolt than steel plates and might be potential candidates as covering and/or casing materials for underwater mines to reduce the acoustical signature against detection and identification.

Utilization of organic fertilisers a potential approaches for agronomic crops: A review
Authors: Dalorima Tahir , Sakimin Siti Zaharah , Shah Ramisah Mohd
Published: February 2021

Organic fertilisers are of biological origin and the amount of nutrients they produce varies greatly. Besides providing the essential macro and micro nutrients, they also provide an array of plant growth-promoting substances. Organic agronomy is a relatively recent technique of farming in developed countries. While several studies were conducted on the impact of organic fertilisers on soil properties and crop production, further research is needed to determine comparative results between organic fertilisers. This paper aims to review some of the influences and impacts of poultry manure, cow dung, goat manure, vermicomposter and seaweed extracts. Much-needed characteristics of numerous crops were enhanced with the appropriate application of these organic fertilisers. Organic fertilizer applications influences the increase of plant heights, vegetative growth, yields and yield attributes. The application of adequate fertilisers also influences the qualitative parameters and post-harvest traits of most crops. Selecting the best organic fertilisers at an optimal application rate that could be the best source of nutrient supplement in cultivating qualitative crops, is a gap that needs to bridge. Therefore, different application rates of the above organic fertilisers were also studied.

Published: February 2021

The utilization of wild plants for livelihood and income generation is a traditional practice adopted by various indigenous communities worldwide. Zanthoxylum armatum DC. is one of the most preferred species harvested from wild and used extensively by the local indigenous communities in the northeastern part of India as well as in the neighbouring countries like Bhutan and Nepal. This species has been widely used by the local tribes as a spice in flavouring various foodstuffs and also for the treatment of numerous health ailments. We studied the distribution, population, ethnobotanical uses and marketing potentials of Zanthoxylum armatum in 12 districts of Arunachal Pradesh during 2018-2019. The study revealed its occurrence in the subtropical and temperate forest of the state with maximum population in forest edges and open forests around agricultural lands of West Kameng and Lower Subansiri districts. The analysis of the population in Shergaon area revealed its good representation with 1.04 /m2 density contributing 0.051 m2/ha. basal cover and 20.011 IVI. Even after its various uses, no cultivation of the species was practised by the local people. The dried fruits that are marketed @Rs. 800-1200/kg in the state are entirely collected from the wild. As the population of the species is limited in most of the area and the supply of fruits is only from the wild, extensive plantation and management practices will serve both the conservation as well the economic gain to the local communities.

Published: February 2021

Agricultural practices such as fertilization considerably influence soil greenhouse gas fluxes. However, the effects of fertilization on greenhouse gases fluxes remain unclear in tea soil when soil nitrogen is low. In the present study, soil CO2 and CH4 fluxes under various fertilization treatments in tea soil were investigated during a 50-day period. The experiment consisted of five treatments: no fertilizer (CK), single nitrogen (urea, N), single oilseed rape cake fertilizer (R), nitrogen + cake fertilizer (2:1, NR1), and nitrogen + cake fertilizer (1:2, NR2). The fertilization proportion of NR1 and NR2 was determined by the nitrogen content of nitrogen fertilizer and cake fertilizer. The results revealed that the single application of nitrogen had no significant effect on soil CO2 flux. However, the addition of cake fertilizer significantly increased CO2 emissions through enhanced soil microbial biomass carbon (MBC). Additionally, CO2 emissions were directly proportional to the amount of carbon (C) in the fertilizer. All treatments were minor sinks for CH4 except for the treatment NR1. Specifically, the cumulative CH4 fluxes of NR1 and NR2 were significantly higher than rest of the three treatments, which implies that application of urea and oilseed rape cake reduced the capability of CH4 oxidation in tea soil. Structural equation models indicated that soil CO2 flux is significantly and positively correlated with soil dissolved organic carbon, MBC and soil pH, while mineral nitrogen content was the main factor affecting CH4 flux. Overall, the application of oilseed rape cake increased the oxidation of CH4 and promoted soil C sequestration but inevitably increased the soil CO2 emissions.

This reﬂective article is based on the experiences of two years of teacher training students from the University of Northampton and the Pedagogical University of Weingarten. This article looks more closely at the beneﬁts that international exchange experiences have afforded the trainee teachers involved and how challenges to the process have been addressed. This reﬂection reveals the value of international exchanges in challenging perceptions and assumptions and how the thinking of the trainee teachers changed following the exchange. This study employs a qualitative approach drawing upon the reﬂections and experiences of the participants through written and spoken data. The ﬁndings reveal trainee teachers developed skills speciﬁc to teaching and in particular teaching languages, and they also demonstrated an increased awareness of non teaching speciﬁc skills such as problem solving and intercultural sensitivity. The reﬂections offer insight into how trainee teachers, use, interpret and subsequently act upon the experiences offered in an international exchange.

Published: February 2021

The focus of the project undertaken is to comprehend, what is the research magistracy in education in the twenty-ﬁrst century. Since the 1990s, when the master’s level of training ﬁrst appeared in the Russian education system, a search was made for its place and role in the system of training highly qualiﬁed personnel for the education system. The central problem of the current stage of the master education development is a triple conjunction: understanding the relationship between research and educational activities; the reﬂection of the contexts, conditions and limitations of research activity in the ﬁeld of education; and the creation of new research programs based on humanitarian discourses in the second half of the twentieth century. The conceptual foundations of the project were built in connection with the ideas of T. Kuhn’s “scientiﬁc paradigms” and I. Lakatos’s “research programs”, which made it possible to establish a correspondence between different educational values and the type of research practices; the ﬁeld approach of P. Bourdieu, which allows the models and resources of research activity to be structured; and structural psychoanalysis by J. Lacan, which provides a new look at research activity. As a result of the article, a generalized image of the developed master’s program “Interdisciplinary Studies in Education” is formulated.

Propiedades físicas de la madera de ejemplares jóvenes de Alnus glutinosa (L.) Gaertn.
Authors: Riesco Muñoz Guillermo , Rodríguez Campos Ana María
Published: February 2021

En el interior de Galicia (noroeste de España) se apeó un grupo de alisos jóvenes para caracterizar su madera analizando probetas sin defectos. Las propiedades físicas obtenidas presentaban una variación entre individuos altamente significativa. Los valores medios corresponden a una madera semipesada y medianamente estable (peso específico al 12 % de humedad: 547 kg/m3; densidad básica: 440 kg/m3; contracción volumétrica: 14,3 %; coeficiente de contracción volumétrica: 0,26 %). La variación entre pies no es atribuible al medio, semejante para todos los árboles, ni a sus dimensiones, que no influyen significativamente en las propiedades de la madera. Solamente la edad del árbol influye significativamente en algunas características. Por tanto, la variación de la madera entre individuos obedece a causas hereditarias, quedando justificado que esta especie sea una fuente de diversidad genética a conservar. Se propone un modelo que describe la variación de la densidad básica a lo largo del fuste (R2 = 0,62; E = 6·10-5 %; RMSE = 5,1 %). La validez del modelo para todos los individuos muestreados y para los seis primeros metros de fuste permite calcular, a partir del volumen de corta, la materia seca que se obtendría al aprovechar las dos o tres primeras trozas comerciales.

The defintions of information and security; history of information security development
Authors: Ibrahimova Aytakin Nazim
Published: February 2021

Taking into consideration its historical evolvement, it is evident that information security is not a new concept. Starting from the very moment of writing down the information, it presents by itself a data that can be protected, stolen, or destroyed. Throughout the whole history, without even perceiving it people had to take steps to guarantee the security of important information that they have been able to maintain. The concept of information security is quite dynamic. A behaviour that is generally accepted today can be a peril to an entity that we will work with tomorrow. Developing technology brings along the continuous innovation. Everyone handles personal information when it comes to technology development or service provision. Besides already existing services, it includes banking and other activities.

Authors: Vaicekauskienė Loreta
Published: February 2021

This paper describes the social value of the global English language as identified in the investigations of various communities worldwide and shows how the social meanings of English relate to each other in a broader ideological field universal for today’s locally global world. The notions of indexical field (Eckert 2008) and bivalent indexicality (Cotter, Valentinsson 2018) are applied in the analysis. The aim of the study is to synthesize results obtained by different researchers from different ideological and communicative contexts and to explore the indexical potential of English, including its local varieties and mixed speech styles. The study is based on a qualitative analysis of a corpus of secondary sources, consisting of a total of 74 scholarly publications from the Expanding Circle communities, which were published in English in 1990–2020 (most of them during the second decade of the 21st century).In total, more than 50 social meanings of the global English language have been identified. It is likely that the abundance of social associations with English is due to the strong first-order indexes. Hence, the social meanings were grouped into the following nine indexical categories based on the presumed first-order sociocultural indexicalities: British and American culture; International sphere; Technologies, science and education; Economic and social status; Personal capital; Youth; Popular culture and media; Urban sphere; and Male. Positive social meanings dominate the indexicalities, but for some of them, bivalent indexicality (presence of contradictory positive and negative values) has been recorded. Although there is much overlap between these relative categories, the constellation as a whole is interpreted as a complex of several separate and multivalent indexical fields. It is to be hoped that this study not only illustrates that the notion of indexical field is applicable for analysis of the imagined global community of users of English, but also provides a broader ideological context for further research of the social meaning-making potential of the global English language.

We give short historical sketch about theoretical researches’ development started at various times at the Institute of Physics of NAS of Ukraine. The emergence and development of research teams and schools, whose creative activity continues today, is embodied through the personal contributions of prominent theorists, their colleagues and students. We describe the emergence and formation of the Institute of Physics as the first research physical institution and a prominent role of the famous Joseph Kosonogov student Alexander Goldmann in the process. It is noted that Profes- sor Leon Kordysh was who began theoretical research at the Institute of Physics continuing the tradition of theoretical studies, initiated at St. Wolodymyr University by Professor Nickolas Schiller and developed by Joseph Kosonogov. After Kordysh's death, Lev Strum known for his originality and masterful approach to complex problems determined the line of theoretical studies for four years. After the Strum liquidation and the Goldmann imprisonment, Rosen had two years of productive work at the Institute of Physics. With the beginning of the German-Soviet war, the Institute was taken to Ufa, where the work was focused on defense, the Institute itself was significantly reduced and merged with the Institute of Mathematics. In 1944, the Institute was returned to Kyiv, headed by Academician Aleksander Lejpunsky, and theoretical research was mainly conducted by Solomon Pekar with his staff and Aleksander Davydov and his group. Up to 1960, Pekar had created a powerful team of theorists, with whom he moved to the newly created Institute of Semiconductors. Since 1964, with the formation of a new theoretical department headed by Davydov, the subject of researches in the properties of molecular crystals has been expanded and deepened. Important for science and the history of theoretical research at the Institute of Physics were several activity years at it by N. N. Bogolubov and Professor Alex Sitenko. Former employees and students of these prominent scientists are now actively moving forward the theory. In fact, the staff of the theoretical department headed by Corresponding Member of our Academy Petro M. Tomchuk works very fruitfully at the Institute of Physics.
DEPENDENCE OF SURFACE PLASMON POLYARITON EXCITATION EFFICIENCY ON ALUMINUM GRATINGS RELIEF DEPTH
Authors:   V. Lashkaryov Institute of Semiconductor Physics of NAS of Ukraine, Indutnyi I.Z.
Published: February 2021

An experimental study of the excitation of surface plasmonpolaritons (SPP) on aluminum diffraction gratings with a fixed period of 519 ± 0,5 nm and a variable modulation depth h/a(where h is the grating depth, and a – its period) was carried out. Gratings with a sine-like profile were formed on vacuum chalcogenide photoresists films by interference lithography and covered with an opaque aluminum film. A Dimension 3000 Scanning Probe Microscope was used to determine the grating groove profile. The characteristics of the SPP were determinedfor28 gratings with h/a ranged from 0,018 to 0,20, by measuring the dependences of specular reflection of p-polarized radiation of He-Ne laser on the angle of incidence, which was defined as the angle between the normal to the substrate plane and the laser beam. It was found that there is an optimal grating relief depth for a given excitation wavelength, which provides the maximum transfer of the incident electromagnetic wave energy to the surface plasmon-polariton mode.The dependence of the SPP excitation efficiency on the grating modulation depth has a maximum at a relatively small value of h/a ≈ 0.086. At such modulation depth the absorption of electromagnetic radiation of the incident laser beam is more than two orders of magnitude higher than the absorption of aluminum film with flat surface at the same angle of incidence. The position of the angle of resonant excitation of SPP practically does not change from h/a= 0,018 up to h/a ≈ 0,06. With further increase of h/a it begins to shift to the region of smaller incidence angles, with the rate of the shift accelerating gradually. With an increase of h/a, a decrease in the depth of the plasmon resonance and a significant increase in its half-width are also observed, and the dependence of the half-width of the SPP band on the modulation depth is close to quadratic. Using this grating-coupled SPP technique, the estimated thickness of air-formed oxide layer on the aluminum gratings surface (about 3.9 nm) is close to the value obtained in the literature with a set of complicated techniques.
ANALYSIS OF FORMING BLOOD ELEMENTS USING SURFACE PLASMON-POLARITON RESONANCE: MODEL OF TRANSITION LAYER

Published: February 2021

Despite the great practical importance, the control of blood by optical methods is enormously complicated by the strong scattering of light. This is especially true for formed blood elements (FBEs), which are a compact suspension that remains after plasma removal from blood by centrifugation. The study of the surface plasmon resonance (SPR) in Kretchman’s geometry together with measurement of the angular dependence of the light internal reflection R( φ ) at the glass/ FBEs boundary is one of the few possibilities to obtain additional information about the structure and molecular composition of this complex inhomogeneous object. Measurement of R( φ ) for contact FBEs with the glass surface allows to determine the total internal reflection (TIR) angle and the effective refractive index N of the binary of erythrocytes-blood plasma mixture. At the same time, the comparison of the angles of TIR and SPR makes it possible to establish the presence of a transition layer between gold surface and the volume of FBEs. In addition, a detailed matching of the experimental dependence R( φ ) with one of calculated curve by regression method allows minimize the objective function and allows to establish a detailed model of the transition layer. The paper shows that the value of N is 1.4003...1.4008. According to the formula of the effective Bruggeman's medium, the packing density of erythrocytes in the volume of FBEs is about 85%, which is well matched with the data known from the literature. At the same time, at least two intermediate layers were detected at the gold /FBEs interface. (1) A layer 33–38 nm thick adjacent to the hydrophobic surface of the gold film and with a refractive index of N p = 1.356–1.357. Presumably, it is a binary phase with a liquid part in the form of water, a buffer solution or blood plasma and a hard part in the form of proteins non-specifically related to gold, most likely molecules of albumin and fibrinogen. (2) A thicker, transition-to- volume FBEs layer is most likely related to the edges curvature and marginal packing of erythrocytes; the effective thickness of this layer is d m = 130-200 nm, and the effective refractive index N m = 1.356... 1.369. The details of this transition layer are currently of considerable practical interest because they can reflect the physiological state of blood cells and whole body, and the parameters d m and N m can be useful from a biological or medical point of view.

Lexical Bundles across levels of Proficiency in Portuguese as a Second Language
Authors: Matte Marine Laísa , Goulart Larissa
Published: February 2021

Formulaic sequences are known for being measures of foreign language fluency for learners. Research in language processing suggests that native speakers as well as learners process these sequences as a single word (ELLIS, 1996). Nevertheless, little is known about the use of formulaic sequences in Portuguese and, even fewer studies have examined the use of formulaic sequences in learners of Portuguese. Therefore, in this study, we sought to investigate the textual function of lexical bundles extracted from a corpus of learners of Portuguese as a Second Language (PSL). Lexical bundles are sequences of three or more words that occur with larger than expected frequency in a specific corpus. In this study, we used corpus linguistics tools to extract lexical bundles that occur frequently at two levels of proficiency – beginner and intermediate – in Portuguese. These bundles were, then, classified according to their textual function. Results indicate that beginner level students use more bundles associated with concrete references, while intermediate learners use more bundles associated with textual organization and stance. This study contributes to the description of Portuguese acquisition at these two levels of proficiency. In addition, the results can foster classroom activities where the PSL teachers introduce new functions of lexical bundles to students. Finally, we hope that this study motivates more research describing the language used at different stages of Portuguese acquisition.
Mapa mental
Authors: Lu Chun Hui
Published: February 2021

O presente trabalho tem como objetivo geral investigar a potencialidade do uso do mapa mental no ensino e aprendizagem da gramática de Português Língua Estrangeira (PLE) por aprendentes chineses. Criado e sistematizado pelo psicólogo inglês Tony Buzan, mapa mental é amplamente utilizado em áreas diversificadas, sobretudo no campo de educação. À luz da teoria cognitiva, descobrimos que esta estratégia, compatível com a cognição humana, poderá contribuir, não só para o esclarecimento e sistematização do conhecimento, mas também para a conexão dos conceitos novos com os prévios, promovendo, por conseguinte, a aprendizagem significativa. Através da análise de dois estudos de caso, acreditamos que o mapa mental, como um recurso complementar, deve ser mais usado e aprofundado, em articulação com outros métodos, num contexto maior.

Satellite thematic maps in geological field studies are an important tool for the delineation, interpretation, representation, and visualization of geological processes, while the development of seismic sections offers an increasingly detailed analysis of subsurface geology and inferring and understanding the subsurface structure of the earth. This combination promoted a fast-growing research in the fields of morphotectonics and neotectonics. The area under investigation is one of the most significant Iraqi places which includes several oil fields. The study area is located in northern Iraq and administratively follows Kirkuk governorate. Landscapes in this area are characterized by asymmetrical, cylindrical and extended folds. Kirkuk, Bai-Hasan and Qarachuq Anticlines reflect these structural elements and their fold axis trends towards northwest-southeast within the Zagros folded zone. The main objective of this study is to use the visual and digital interpretation of Landsat image to discriminate the sudden breaks and omissions of rock beds in the study area. Therefore, a morphotectonic map was created, the accurate location of the sudden breaks was provided and the zones affected by tectonic deformation, which left its imprint on the successive lithological units were detected. Seismic data were used to assess the tectonic impact on subsurface formations and their reflections on exposure rocks. The seismic lines were selected based on the locations of the identified sudden breaks as interpreted from satellite images. The hypothesis derived from this study is that the sudden breaks in the study area were triggered by a series of faults. In addition, the region was affected by the vertical stresses resulting from these faults and morphological aspects of the region were determined by the temporal variations of the above stresses.
