Optical signal processing for indoor positioning using a-SiCH technology

Abstract. We use the nonlinear property of silicon carbon (SiC) multilayer devices under UV irradiation to design an optical processor for indoor positioning. The transducer combines the simultaneous demultiplexing operation with photodetection and self-amplification. The proposed coding is based on SiC technology. Based on that, we present a way to achieve indoor localization using the parity bits and a navigation syndrome. A representation with a 4-bit original string color message and the transmitted 7-bit string, the encoding and decoding of accurate positional information processes, and the design of SiC navigation syndrome generators are discussed and tested. A visible multilateration method estimates the position of the device using the decoded information received from several noncollinear transmitters. The location and motion information is found by mapping position and estimates the location areas. Since the indoor position of the light-emitting diode light source is known from building floor plans and lighting plans, the corresponding indoor position and travel direction of a mobile device can be determined.
Morphometric parameters of the relief and drainage network of the Formiga River subbasin, Minas Gerais, Brazil

: This research analyzed the morphological/morphometric parameters of the relief and drainage network of the Formiga River subbasin, southern Minas Gerais State, Brazil, aiming at identification and the exam the influences of control mechanisms in the development of current configurations. The methodology was based on the application of indices and parameters: (1) slope length (Hack's Sl); (2) normalized slope index (Ksn); (3) river hierarchy; (4) drainage density; (5) hydrographic density; (6) sinuosity index; (7) density of structural lineaments; (8) transverse topographic symmetry factor; (9) asymmetry factor of drainage basins; (10) topographic profiles transverse to the valleys; (11) relief ratio; (12) roughness index; (13) roughness concentration index; (14) compactness coefficient; (15) circularity index; and (16) form factor. The results indicated three sectors with distinct geomorphic behaviors, which resulted in peculiar surface structures and divergent current dynamics. The Formiga River subbasin presents physical evidence that demonstrates and corroborates with the structural control in the development of the current drainage network and relief. The construction of dams affected the dynamics of the lower course of the river, drowned by the reservoir of the hydroelectric plant of Furnas.
Forensic toxicology: importance in crime investigation

By using chemical and analytical techniques, forensic toxicology contributes to the establishment of facts in forensic investigations by studying the medical and legal aspects of the detrimental effects of a drug on organisms. Forensic practises is crucial in cases of deadly poisoning and those that could be connected to criminal activity. In most murder, suicide, or accident cases, poisons are discovered. They are a crucial component of the silent weapon that silently and covertly ends life. The current study is focused on the field of forensic chemistry and toxicology, which is entirely centered on the introduction, categorization, effects, and influencing factors of poisons, as well as their detection and testing. This article's goal is to examine how they behave and perform after they enter the human body. Poisons have serious effects and might even be fatal if not treated appropriately.
Quantifying the Key Factors Affecting the Escape of Planetary Atmospheres

The habitability of Earth-like planets is an increasingly important subject in astrophysics and in planetary sciences. Atmospheric escape plays a vital role in the evolution of the habitability of Earth-like planets. By systematically analyzing the numerical simulation results of the interactions between the planetary atmospheres and the stellar winds, in this work, we evaluate various factors related to the atmospheric nonthermal ion escape rates, including planetary parameters (e.g., mass, density, radius, semimajor axis, etc.) and stellar wind parameters (e.g., density, velocity, and interplanetary magnetic field (IMF) strength). Furthermore, we determine and quantify the key factors affecting the planetary atmospheric nonthermal ion escape rates. Our results show that the correlation coefficients between planetary atmospheric nonthermal ion escape rates and stellar wind density, IMF strength, and the ratio of the planetary radius to the planetary semimajor axis are 0.98 (0.88), 0.95 (0.81), and 0.87 (0.59), respectively, in the scenario of maximum (minimum) dynamic wind pressure. This means that the planetary atmospheric nonthermal ion escape rates increase with the increasing stellar wind density, the increasing IMF strength, and the increasing ratio of the planetary radius to the planetary semimajor axis. Generally, the nonthermal ion escape rates of planetary atmospheres are more sensitive to stellar wind parameters than to others. In addition, we determine the functional relations of the above three significant parameters for evaluating and quantifying the effects of such key physical factors on the nonthermal ion escape rates of the planetary atmospheres. Our findings will be very useful for better understanding the key factors that influence the escapes of planetary atmospheres.
Suitability Assessment of CsPbI_3 Dosimeter with ^192Ir Source for Brachytherapy Quality Assurance

In brachytherapy, quality assurance (QA) is a prerequisite to minimize the dose irradiation to the healthy tissues in patients during treatment, as it evaluates the accuracy of the dose applied to the patients as well as the accuracy of the position of the irradiation. Therefore, a strong emphasis has been placed on brachytherapy QA in clinical practice. This study assessed the suitability of a CsPbI3 dosimeter for the brachytherapy QA system. To verify the reliability of the unit cell sensor fabricated with CsPbI3, the electrical parameters were evaluated, after which the position dependence of the sensor was analyzed. A high level of reliability (R 2 > 0.99) and reproducibility (relative standard deviation < 1.5%) were observed. The maximal value measured at the isocenter of the sensor as the distance of the dosimeter from the irradiation source was gradually decreased. When the optimal angle was assessed, the variation was as high as 5.01 nC depending on the form of the 192Ir source. Therefore, the CsPbI3 dosimeter fabricated in this study is a suitable substitute for the conventional QA dosimeter.
First-principles effective Hamiltonian simulation of ABO3-type perovskite ferroelectrics for energy storage application

Dielectric materials with high power density and energy density are eagerly desired for the potential application in advanced pulsed capacitors. Here, we present the first-principles effective Hamiltonian simulation of perovskite ferroelectrics BaTiO3, PbTiO3, and KNbO3 in order to better predict and design materials for energy storage application. The lattice constant, dielectric constant and ferroelectric hysteresis, and energy-storage density of BaTiO3, PbTiO3, and KNbO3 were calculated with the consideration of the effects of temperature and external electric field.
Optimization of Treatment Planning Parameters used in Tomotherapy for Breast Cancer Patients

Aim: To study the effect of various planning parameters viz field width (FW), pitch factor (PF) on breast tumor and evaluate the relation among these parameters and their influence on the quality of plan and the treatment time. Material and method: Nine plans for each of the ten breast cancer patients were created taking various combinations of field width (FW) and pitch keeping the Modulation factor (MF) constant 3. The reference plan selected for the study is field width of 1, pitch 0.215. Other plans were created keeping the same constraints and penalty as the reference plan and 1000 iterations. Target coverage was evaluated in terms of conformity index (CN) and homogeneity index (HI) while the sparing of organs at risk (OARs) were evaluated in terms of mean, maximum and relevant dose volumes. Low dose spillages in normal tissues were also evaluated. The plans are compared with the reference plan using the Wilcoxon Signed Ranks Test. Concept of plan Quality index is also used to evaluate the plans qualitatively. Results: The mean treatment delivery time for 5, 2.5 and 1.0 cm FW plans were 5.04 ± 0.4, 8.51 ± 0.87 and 20.67 ± 2.02 minutes respectively. There was no significant variation in doses for OARs and COIN and HI of targets for 1 cm and 2.5 cm plans except for 5 cmplans. But the low dose spillage increased by 9-14% and 23-43% for 2.5 and 5 cm respectively. Conclusion: Dose to the OARs was not significantly higher for 2.5_FW plans from the reference plan but, significantly higher for 5_FW. Larger the FW and higher the pitch, spillage were more. On the basis of our analysis, 2.5_0.215 plan with MF=3, can be considered as the optimum plan for unilateral breast treatment using Tomotherapy.
Research on composite manufacturing method of semi-buried 1×32 optical splitter

In this paper, a composite manufacturing method was proposed to reduce the inner surface roughness of silica groove. Firstly, femtosecond laser was used to ablate the silica groove, then, a 5% concentration hydrofluoric acid solution was used to corrode the inner surface of silica groove. Sec-ondly, Su8 adhesive was filled with the groove to form a semi-buried 1×32 optical splitter by doctor blade. The test results showed that the surface roughness Ra was less than 0.2 µm, and average insertion loss of output ports was 21.34 dB, moreover, the uniformity was less than 1.44 dB. Compared with the traditional femtosecond laser ablating method, surface roughness reduced by at least 0.1 µm, and the average insertion loss of output ports was reduced by 1.22 dB, and the uniformity was reduced by 0.41 dB. So, the composite manufacturing method improved the communication performance. It is satisfied with the requirements for optical interconnection in the electro-optical printed circuit boards.

It refers to the way in which everything is made explicit and obvious in the speech and nothing is left to the imagination. However, the purpose of this study is to determine how conversational explicature is recognised and produced by university students. The data is collected using two different forms of multiple-choice discourse completion tasks, and the results are analysed using a method of quantitative analysis. 100 male and female students from Wasit University's English department at College of Education for Humanities made up the study's sample. The test has been carried out on March 30, 2022. It has been found that university students are able to recognise and produce conversational explicature so the study's objectives are accomplished. University students exhibit a discernible aptitude for recognising and creating conversational explicature, according to the study's findings.
Using the Process Writing Approach based on Padlet Application (PA) to Enhance EFL Argumentative Writing Competence

This research looked at how using a process writing technique using the Padlet application (PA) influenced the argumentative writing of undergraduates majoring in English as a foreign language (EFL). Sixty students in their fourth-year in English language and translation major made up the study's subjects. Then, they were randomly assigned to one of two groups (N=30 total): the experiment group or the control group. Participants' ages varied between 19 and 20. There was no attempt to control the subjects' sex identities. Quasi-experimental techniques were used to gather quantitative data in this study through pre- and post-tests. The Padlet app and a process writing methodology were used to instruct the experimental group in argumentative text writing, while more conventional methods were used to instruct the control group. For two and a half months, researchers worked with EFL majors to find ways to strengthen their argumentative writing. The experimental group's performance in writing argumentative prose using the process writing approach based on the Padlet application was substantially higher than that of the control group, as determined by an independent sample T-test. The students were also quite enthused about utilizing Padlet application.
EMG BASED CONTROL OF WRIST EXOSKELETON

: The significance of human motion intentions in a designed exoskeleton wrist control hand is essential for stroke survivors, thus making EMG signals an integral part of the overall system is critically important. However, EMG is a nonlinear signal that is easily influenced by several errors from its surroundings and certain of its applications require close monitoring to provide decent outcomes. Hence, this paper proposes to establish the relationship between EMG signals and wrist joint angle to estimate the desired wrist velocity. Fuzzy logic has been selected to form a dynamic modelling of wrist movement for a single muscle at different MVC levels and double muscles at a similar MVC level. The physical model of the exoskeleton hand using Simmechanics Matlab software has been developed to validate the performance of the fuzzy logic output result from both dynamic modelling approaches. A PID controller has been developed to smooth the exoskeleton hand movement fluctuations caused by the fuzzy logic decision-making process. As a conclusion, results showed a strong relationship between EMG signals and wrist joint angle improved the estimation results of desired wrist velocity for both dynamic modelling approaches hence strengthened
Nonlocal transient electrothermomechanical vibration and bending analysis of a functionally graded piezoelectric single-layered nanosheet rest on visco-Pasternak foundation

ABSTRACT This study develops the transient thermoelectromechanical vibration and bending analysis of a functionally graded piezoelectric nanosheet rest on visco-Pasternak’s foundation. Nonlocal elasticity theory as well as classical plate theory is used to implement basic equations of the nanosheet. The plate is resting on visco-Pasternak’s foundation and subject to mechanical, thermal, and electrical loadings. Hamilton’s principle is used for derivation equations of motion in terms of displacement components. As a first case study and for validation of the responses of the system, nonlocal vibration analysis of nanosheet is studied. The effects of nonlocal parameter and nonhomogeneous index of nanosheet are studied on the fundamental frequencies of the system. As the main objective of this study, the electrothermal bending results of the nanosheet are studied. The effects of some important parameters such as nonlocal parameter, nonhomogeneous index, thickness, distribution of electric potential, and damping are calculated on the maximum deflection of the sheet under various thermal and electrical loadings.
THE APPLICATION OF FORCE MAJEURE IN THE RESOLUTION OF UNPAID DEBTS AT BANKING INSTITUTIONS RESULTING FROM NATURAL DISASTERS

– The objective of this study was to examine how non-performing credit agreements resulting from natural disasters associated with force majeure are settled, and the measures taken by banks to resolve bad loans. The research employed both juridical normative and descriptive analytic methods, analyzing primary and secondary data and evaluating them qualitatively with the help of legal provisions. Qualitative descriptions were used to reinforce the previous description and answer the fundamental questions, thus leading to valuable conclusions and suggestions. The findings of the study disclosed that credit contracts did not have any regulations regarding force majeure, making it challenging for banks to execute them. This resulted in debtors, mainly being farmers, encountering issues in paying off their loans. The strategy to tackle non-performing loans was to clear any credit owed by individuals who had been relocated. This approach provided legal protection by granting certainty for people affected by natural disasters

ENHANCEMENT OF ANTIOXIDANT CAPACITY IN WHEAT (

Low temperature stress is one of the important environmental factor affecting the growth and development of wheat. As a widely existing hormone, salicylic acid do not only improve the immunity of wheat, but also improve the cold resistance capability of wheat. In the present study, effects of foliar spray of 0.3 g/l Salicylic acid (SA) on the cold resistance of wheat were studied under low temperature stress condition. Results showed that exogenous salicylic acid could enhance the activity of wheat antioxidant enzymes, reduce the content of Malondialdehyde (MDA) and change its own starch and sucrose synthesis, amino acid synthesis, carbon metabolism and glycolysis by affecting the differential expression of different hormone signal transduction genes and thereby improving the cold resistance of wheat.

Bright Multicolored Photoluminescence of Hybrid Graphene/Silicon Optoelectronics

Graphene does not possess a band gap, and hot carrier relaxation in graphene is an ultrafast processs. This leads to a very low emission efficiency of graphene. We demonstrate bright multicolored frequency-upconverted photoluminescence from graphene via three-photon absorption by femtosecond laser injection at a communication wavelength 1.57 μm. The broadband and multiwavelength emission from graphene is based on the model of ultrafast electron–hole pair recombination and asymmetrical energized electron–hole radiation recombination in graphene. Furthermore, we show photoluminescence variation with blue light emission in the graphene/silicon hybrid system, with 2–3 orders of emission efficiency increase. The results demonstrate hot carrier multiplication and hot carrier scattering in graphene and could help to study the population inversion and broadband lasing of graphene.
SERVANT LEADERSHIP AND ITS RELATIONSHIP TO PERFORMANCE: A SYSTEMATIC LITERATURE REVIEW

The purpose of this research article is to provide a specific description of the relationship between servant leadership and individual, team and organizational performance. Methodologically, a rigorous three-phase systematic literature review process has been followed to identify relevant information to answer the review questions. In this way, the results are presented and disseminated in a descriptive manner. It has been found that the studies are mostly quantitative, focused on studying the relationship between servant leadership and performance at the individual level, followed by organizational performance and few studies focused on team performance; with a growing interest in multilevel performance; there is a greater presence of mediating variables than moderating variables in the research. Although there is much interest in the subject, it is believed that it is little studied, mainly in team performance and moderating variables. The study contributes with specificity by addressing the effect it has on performance at the individual, team and organizational levels. In addition, new topics for further research are raised.
