Published: June 2020

Thermocatalytic sensors are widely used in gas analysis systems and have high reliability and low cost. However, errors in measuring the concentration of combustible gases related to the non-linearity of the conversion characteristic and the influence of ambient temperature fluctuations significantly limit the scope of their application.Purpose of reseach. Development of a method for measuring gas concentration by thermocatalytic sensors, which allows reducing measurement errors by tuning out due to ambient temperature influence and linearization of the conversion characteristic.Problems. They are as follows: to develop a method for temperature stabilization of a thermocatalytic sensor; to make a structural and functional scheme for the sensor activation; to obtain a mathematical description of the method and substantitation for tuning out as a result of temperature influence; to experimentally confirm the possibility of linearization of the sensor conversion function in the thermal stabilization mode.Methods. The mathematical description of the method applies the theory of heat transfer and the theory of electrical circuits with discrete signals. When analyzing existing solutions and synthesizing the device, methods for calculating circuits with nonlinear elements and the theory of measurement systems have been used. The real conversion function has been obtained through an experimental method.Results. A method for measuring gas concentration by a thermocatalytic sensor with the use of a microcontroller and PWM has been developed. It allows reducing errors due to tuning out as a result of ambient temperature influence. A mathematical description of the method has been given. An experiment has been performed. It demonstrates the effectiveness of using temperature stabilization to linearize the conversion characteristic.Conclusion. The paper proposes a method for temperature stabilization of thermocatalytic gas sensors. The method makes it possible to increase the accuracy of measurements by tuning out due to the influence of temperature fluctuations and linearization of the conversion function.

Purpose of research is to develop a methodology that allows designing EDM electrodes applying advanced computer-aided design (CAD) systems by forming the tool’s working surface with geometry which is inverse equidistant to the geometry of a given workpiece taking into account the EDM gap, working translation or translation-rotational motion of EDM electrodes, the value of the layer of conductive coating based on the technological parameters of the processing procedure. It is also necessary to propose, implement and formulate technological guidelines for manufacturing EDM electrodes from dielectric materials by additive techniques with the subsequent formation of a conductive layer on them; the value of the layer should ensure the flow of working electrical processes in the EDM gap and the necessary tool life. This will make it possible to expand the scope of application of combination EDM electrodes as applied to combined processing techniques which are characterized by a wide variety of working surface shapes, which correspond to the geometry of the workpiece, which is not limited by the degree of curvature, has by far lower cost and high processability when creating a special tool for pilot and single manufacturing.Methods. When carrying out the work, theory of the classical laws of mechanical engineering technology, electrical processing techniques, the known laws of rapid prototyping and additive technologies were used.Results. The theoretical foundations and the technology for manufacturing combination EDM electrodes by rapid prototyping have been developed and a methodology for calculating and designing the working part of EDM electrodes has been proposed taking into account the geometric parameters of the machined surface and a variable EDM gap value.Conclusion. The mechanism of EDM electrode design by means of digital prototyping in modern CAD systems is justified taking into account the features of the workpiece geometry, EDM gap and metallization material.
Investigation of the Operation of the Extended Kalman Filter Supplemented by an Adaptive Digital Filter for Integrating Data from a Mobile Robot Control System
Authors: Bezmen P. A. 
Published: June 2020

Purpose of reseach. The article deals with the study of the operation of the extended Kalman filter (EKF), supplemented with an adaptive digital filter in order to compensate for the error in the operation of the EKF when performing data integration of the mobile robot control system.Methods. The adaptive digital filter (ADF) is a self-tuning filter that iteratively changes its variable parameters to achieve the optimal desired values of the output data. The EKF supplemented with the ADF with the NLMS adaptation algorithm will be called the EKF–ADF system or the EKF+NLMS digital filter. An important task is the selection of the number of frames and ADF weighting coefficients at which the optimum quality of noise suppression and the convergence rate of the adaptation algorithm are achieved.Results. With various options of organizing the operation of the ADF buffer memory, the adjusted values for assessing the state of the ‘mobile robot–environment’ system may differ. When the number of input data frames and ADF weighting coefficients are small, low quality noise suppression will be observed. With an increase in the number of frames and weighting coefficients, the quality of noise suppression is improved, and the convergence rate of the adaptation algorithm decreases.Conclusion. The EKF+NLMS digital filter algorithm takes an intermediate place between the EKF algorithm and the serial filtering of the EKF and ADF signals with the NLMS algorithm according to the criteria for estimating the mean square error, mean absolute error, signal-to-noise ratio, and convergence rate.

ABSTRACT
Tuberculosis (TB) is a disease that has become one of the global concerns. Various factors can increase the incidence of TB and facilitate transmission, one of which is environmental factors. This study aimed to understand the correlation between altitude, population density, and healthy home coverage with the proportion of smear-positive pulmonary TB in Pariaman, Bukittinggi and Dumai in 2010-2016. This study is an ecological study. The data of smear-positive pulmonary TB cases obtained from District Health Office were processed in aggregate at each sub-district in Pariaman, Bukittinggi and Dumai areas. Data were analyzed by correlation test and spatial analysis. The results of this study indicate that there is a strong correlation between altitude with the proportion of smear-positive pulmonary TB in Bukittinggi with direction of the correlation is negative, which mean that the higher the altitude the lower the pulmonary Tb case. It is suggested that area with lower altitude can focus more on promotion and prevention of pulmonary TB through health education or other health promotion measures.

A candidíase bucal é uma doença infecciosa fúngica causada principalmente pela Candida albicans, cujas manifestações clínicas podem estar vinculadas a fatores locais e sistêmicos. O objetivo deste estudo foi avaliar a associação entre fatores como
tabagismo, alcoolismo, anemia, diabete, antibioticoterapia, corticoterapia, radioterapia, quimioterapia e soropositividade para
o HIV com as diferentes formas clínicas da candidíase bucal. Foram analisados 303 prontuários de pacientes com candidíase bucal,
atendidos no período de 1990 a 2000, dos quais foram excluídos aqueles que apresentavam candidíase associada ao uso de prótese.
Dos 90 prontuários incluídos no estudo, observou-se que 62 pacientes (68,9%) apresentavam uma das formas clínicas da doença e
que 28 possuíam associação entre duas (26,7%) ou três (4,4%) formas. A apresentação clínica mais prevalente foi a eritematosa
(38,9%), seguida pela pseudomembranosa (37,8%), leucoplásica (27,8%), queilite angular (21,1%) e glossite romboidal mediana
(GRM) (10%). A forma leucoplásica foi associada com o tabagismo (p=0,01), enquanto a candidíase eritematosa teve associação
com anemia (p =0,04). A candidíase pseudomembranosa apresentou relação estatisticamente significante com antibioticoterapia
(p=0,01), radioterapia (p=0,05), quimioterapia (p=0,02) e soropositividade para o HIV (p=0,01). A queilite angular e a GRM não
foram estatisticamente associadas aos fatores estudados. Concluiu-se que existe associação entre a forma de apresentação clínica
da candidíase bucal e determinados fatores locais e sistêmicos.
Auditing the Blockchain Oracle Problem
Authors: Sheldon Mark D. 
Published: June 2020

ABSTRACTBlockchain brought about the potential for improved data reliability, but only when those data are the result of transactions that happen completely within a blockchain. The reliability of blockchain data is threatened when information is introduced from the outside world, such as when oracles are used to observe occurrences and provide this information to smart contracts. This specific threat to the reliability of blockchain data is known as the oracle problem. This study offers a working definition of blockchain oracles and argues that they should be viewed as service organizations under the auditing standards from the AICPA and PCAOB. The study then discusses risks associated with the oracle's function of collecting, storing, transforming, and transmitting information, and proposes control objectives for auditors to consider when evaluating the information provided by oracles. Finally, the study closes by discussing open questions the audit profession still needs to address with the oracle problem.
Lesing som protestantisk utfordring
Authors: Apelseth Arne 
Published: June 2020

Mindre enn hundre år etter Gutenberg var trykkpressa blitt eit nøkkelelement i det som nokre har framstilt som ein «endringsmekanisme» som skapte «kommunikasjonsrevolusjon». Andre har heller sett trykkpressa som ein teknologi for å konsolidere institusjonell makt og dermed også grepet om samfunn og innbyggjarar. Relasjonar mellom statsmakt og prentemediet skapte nye standardar for personretta kontroll. Samstundes medverka protestantismen med hjelp av prenta medium sterkt til å gje skriftkultur tilnærma allmenn relevans, især ved å endre trongen for bøker og ved å forme vilkår for bruken. Ein vesentleg grunn låg i protestantismens personreligiøsitet, dvs. i vektlegginga av det særeigne forholdet mellom den einskilde og guddomen. Grunnlaget var Luthers fem maksimar, som vart omgjort til ein praktisk handlingsregel om at lekfolk ved sjølvsyn skulle kome til sann erkjenning gjennom individualisert bibellesing.

Background In the case of immigrant health and wellness, data are the key limiting factor, where comprehensive national knowledge on immigrant health and health service utilisation is limited. New data and data silos are an inherent response to the increase in technology in the collection and storage of data. The Health Data Cooperative (HDC) model allows members to contribute, store, and manage their health-related information, and members are the rightful data owners and decision-makers to data sharing (e g. research communities, commercial entities, government bodies).
ObjectiveThis review attempts to scope the literature on HDC and fulfill the following objectives: 1) identify and describe the type of literature that is available on the HDC model; 2) describe the key themes related to HDCs; and 3) describe the benefits and challenges related to the HDC model.
MethodsWe conducted a scoping review using the five-stage framework outlined by Arskey and O’Malley to systematically map literature on HDCs using two search streams: 1) a database and grey literature search; and 2) an internet search. We included all English records that discussed health data cooperative and related key terms. We used a thematic analysis to collate information into comprehensive themes.
ResultsThrough a comprehensive screening process, we found 22 database and grey literature records, and 13 Internet search records. Three major themes that are important to stakeholders include data ownership, data security, and data flow and infrastructure.
ConclusionsThe results of this study are an informative first step to the study of the HDC model, or an establishment of a HDC in immigrant communities.
A Study on Genocide and Infamous Massacre Through The Work Of Elizabeth Cook-Lynn
Authors: Varma Abhishek 
Published: June 2020

There are tens and hundreds of mass killings against a particular community or caste. These massacres have taken the front seat when a caste or community is provoked against some other community. This research is on Elizabeth Cook-Lynâ€™s book on the mass killings of a community infamously known as the Wounded Knee Massacre. This is an ongoing struggle of indigenous Americans of the twentieth century. She pays her tribute to the people killed in this massacre. The people there at the Wounded Knee went suffered a lot. They had to bear the loss of dear family members and community people. There are many other genocides taken place in the world against a community.
