The article is dedicated to the investigation and interpretation of semantic and functional features of phraseological expressions and paroemias referring to tauromachy (bullfighting) within the framework of cognitive and linguoculturological approaches. The introduction of relevant examples in the article aims to detect these features. Tauromachy which is called "an art of bullfighting" is an inseparable part of Spanish culture. Corrida (bullfight) has deep historical roots and it is a specific, festive occasion belonging to the Spanish people. It has entered into the national consciousness of Spaniards, developed and reflected in all manifestation forms of their lives. In its turn, it has lead to the linguistic reflection of tauromachy vocabulary in the language. According to their use in the language, tauromachy terms have four levels: words referring to tauromachy which is a special field and used only in the bullfight, tauromachy words with figurative meaning that can be used as a methaphora in other fields, tauromachy words used in literature and words referring to tauromachy field used in spoken language. Linguoculturological approach is a new stage of the study of complex relations between language, thinking and culture within the framework of cognitive linguistics. Linguistic and semantic aspects of cognitivism, that’s, mental imaginations of a language speaker are observed more vividly in phraseological expressions and paroemias. In the article we will try to study phraseological expressions and paroemias referring to tauromachy used in the spoken language, that’s, the fourth level of the use of tauromachy vocabulary in the language. It is obvious that the phraseological system generalizes language units with extremely great value in terms of understanding the level of national language consciousness of the people. Phraseological expressions and paroemias can be considered precious linguoculturological source, so that daily lifestyle, world outlook, traditions of language speakers are reflected in the phraseological system visually through metaphoric coding. The vocabulary of tauromachy in this field has gone through certain processes and gained new connotative meanings and assists in more concrete, laconic, expressive delivery of the idea being used in the spoken language.

In this research, an Arduino-based data logger has been designed with a MicroSD card data storage media and a MS Excel data format. Power parameters are obtained using a voltage sensor module with the principle of a voltage divider and a current sensor with a shunt resistor. The radiation intensity is obtained from the Solar Power Meter sensor using a RS232 to TTL cable interface. The results show the average of voltage error is 36 mV or inaccuracy is 0.41% for the measurement range from 0.7 V to 24 V, while the average of current error is 10 mA or inaccuracy is 0.42% for the measurement from 0.3 A to 7.5 A. This inaccuracy value is still below the average value of standard measurement tools on the market about 1%, so the results of this design can be used for the purpose of measurements.Keywords: voltage, current, power, solar irradiation, Arduino

This paper demonstrates a method of estimating several key vehicle states—sideslip angle, longitudinal velocity, roll and grade—by combining automotive grade inertial sensors with a Global Positioning System (GPS) receiver. Kinematic Kalman filters that are independent of uncertain vehicle parameters integrate the inertial sensors with GPS to provide high update estimates of the vehicle states and the sensor biases. Using a two-antenna GPS system, the effects of pitch and roll on the measurements can be quantified and are demonstrated to be quite significant in sideslip angle estimation. Employing the same GPS system as an input to the estimator, this paper develops a method that compensates for roll and pitch effects to improve the accuracy of the vehicle state and sensor bias estimates. In addition, calibration procedures for the sensitivity and cross-coupling of inertial sensors are provided to further reduce measurement error. The resulting state estimates compare well to the results from calibrated models and Kalman filter predictions and are clean enough to use in vehicle dynamics control systems without additional filtering.

Four Levels

In this paper, we describe technopoiesis as the complex dynamics between four levels of an all-encompassing knowledge configuration. The first level corresponds to the interaction with the environment, mediated by representations and material forms. The second level involves the representations, for instance representations of force, which determine the interaction with the environment. The third level involves the use of material forms in the interaction, for instance using a stick to get hold of a piece of fruit. The fourth level is the technological level as such. From a view of Biopoetics that primarily understands technopoiesis as a synergic and dissipative process based on emergence and feedback conditions, our main contribution in this study consists in a dynamicist description of how these four levels interact with each other. Higher levels emerge from the lower ones, in a complex but deterministic process, where lower levels are also constrained by the higher ones.

I argue that Kant has developed a broad systematic account of the architectonic functionality of pure reason that can be used and advanced in contemporary contexts. Reason, in the narrow sense, is responsible for the picture of a well-ordered universe of science consisting of architectonic ideas of science, sciences and parts of sciences. In the first section (I), I show what Kant means by the architectonic ideas by explaining and interrelating the concepts of (a) the faculty of reason, (b) ideas (as principles), (c) method, and (d) sciences of reason. Thereafter (II), I think through his holistic understanding of science and scientific progress and suggest differentiating between four levels of use of architectonic ideas, drawing on the metaphor of a well-structured universe as imagined by Kant in his work on the Universal Natural History and Theory of the Heavens. I also claim that each possible idea of reason can be (apart from its primary function) additionally regarded as a fourth-level architectonic concept when explicitly conceived as an object of (e. g. philosophical) studies, i. e. from a mere methodological perspective. In the final section (III), I unveil the potential of Kant’s theory by pointing out how this architectonic methodological function of pure reason is tacitly used in Karl-Otto Apel’s contemporary philosophical research programme.

The contribution of waqf as an instrument of Islamic philanthropy is seen as important in providing social benefits in meeting the long-term needs of the ummah. The contribution of waqf cannot be separated from the existence of nadzir as a waqf manager. The existence of nadzir (waqf manager) is seen as the responsibility of the party responsible for the productivity of waqf assets previously not included in the terms and laws of traditional waqf in Indonesia. The purpose of this study was to analyze the existence and existence of nadzir in the perspective of waqf institutions in Indonesia. This research uses descriptive analytical method, using secondary data obtained from existing manuscript sources, one of the waqf laws. The data analysis in this study is based on a framework of four levels of institutional economy. The findings in this study are the institutionalization process of nadzir as an official institution in waqf management being analyzed using the four level of institutional economic, the first level I the institutionalization process for waqf managers in Indonesia based on customary law and then Islamic law. The second level formal institutional rules place the law as the formal management rule for waqf after the formation of the Republic of Indonesia. The third Level institutions related to waqf institutional governance that experienced improvements after the issuance of formal rules accompanied by guidance from the waqf accounting standards and the waqf core principles. Fourth Level of institutions related to the management of waqf resources in Indonesia provides wide opportunities for nadzir (waqf managers) to manage waqf. The role of the government in private waqf managers in Indonesia is as protector and issuer of regulations that support waqf productivity.

ABSTRACTObjectiveWe hypothesize that COVID-19 case growth data reveals the efficacy of NPIs. In this study, we conduct a secondary analysis of COVID-19 case growth data to compare the differences in the effectiveness of NPIs among 16 representative countries in the world.MethodsThis study leverages publicly available data to learn patterns of dynamic changes in the reproduction rate for sixteen countries covering Asia, Europe, North America, South America, Australia, and Africa. Furthermore, we model the relationships between the cumulative number of cases and the dynamic reproduction rate to characterize the effectiveness of the NPIs. We learn four levels of NPIs according to their effects in the control of COVID-19 growth and categorize the 16 countries into the corresponding groups.ResultsThe dynamic changes of the reproduction rate are learned via linear regression models for all of the studied countries, with the average adjusted R-squared at 0.96 and the 95% confidence interval as [0.94 0.98]. China, South Korea, Argentina, and Australia are at the first level of NPIs, which are the most effective. Japan and Egypt are at the second level of NPIs, and Italy, Germany, France, Netherlands, and Spain, are at the third level. The US and UK have the most inefficient NPIs, and they are at the fourth level of NPIs.ConclusionsCOVID-19 case growth data provides evidence to demonstrate the effectiveness of the NPIs. Understanding the differences in the efficacy of the NPIs among countries in the world can give guidance for emergent public health events.

Recent demand on the navigation systems is very high in many applications such as transportation and environment control. The inertial navigation system (INS) is not only suffering from errors caused by inertial sensors but also the vehicle dynamic. In this paper, the vibration analysis of the land-vehicle is applied for a special INS/GPS integration. The Strapdown INS (SINS) using two Kalman Filters (KF) has been built so that the system can be operated flexibly between feedforward and feedback modes in case of GPS outage. The experiment results show that this INS/GPS system can be used for practical applications

Genetic has a broad and complicated topic and abstract material considered difficult by students. The inability to connect and construct between genetic concepts properly causes misconceptions. Therefore, the purpose of this study was to analyze students' misconceptions on the concept of genetics using a four-tier diagnostic test. 91 students from the Faculty of Education, Department of Biology, University of Riau were used as samples. The method was descriptive quantitative with a survey research model. The four-tier diagnostic test instrument consists of four levels: the first stage uses multiple-choice questions with four distractors questions and one key answer; the second level is the level of student confidence to choose the answers; the third level is the students' reasons for answering the questions; the fourth level is the level of student confidence to choose reasons. The number of questions tested was 20 questions with six sub-concepts. Confidence Discrimination Quotient (CDQ) and four-tier diagnostic test were used to analyze data on misconceptions and interpretation of student answer patterns. Students experienced misconceptions on 19 answer questions, 13 reason questions, and 16 answer and reason questions. The results of the four-tier diagnostic test described that the category of misconceptions was 65.21%, not understanding the concept was 24.53% and understanding the concept was 10.34%. From the six sub-concepts tested, the highest score of misconception was found in genetic material (75.1%) and the lowest was found in the scope of genetics (44.4%). On average, the students had medium and high categories of misconception
