AbstractAsymptotic approximations to the Green's functions of Sturm–Liouville boundary-value problems on graphs are obtained. These approximations are used to study the regularized traces of the differential operators associated with these boundary-value problems. Various inverse spectral problems for Sturm–Liouville boundary-value problems on graphs resembling those considered in Halberg and Kramer's ‘A generalization of the trace concept' (Duke Mathematics Journal27 (1960), 607–617), for Sturm–Liouville problems, and Pielichowski's ‘An inverse spectral problem for linear elliptic differential operators' (Universitatis Iagellonicae Acta Mathematica27 (1988), 239–246), for elliptic boundary-value problems, are solved.

The paper considers a nonlocal boundary value problem for a mixed hyperbolic-parabolic equation of the third order. The equation is considered in a finite simply connected domain consisting of a hyperbolic and a parabolic part. The solution to the problem posed is considered for various cases of the parameter λ, which is in the original equation. In the case when (1-2m)/2< <λ<1, the solution of the problem is reduced to a singular integral equation, which is reduced by the well-known Carleman-Vekua method to the Fredholm integral equation of the third kind. In the case when λ=(1-2m)/2, a theorem on the existence and uniqueness of a solution to the problem posed is formulated and proved. To prove the uniqueness of the solution, the method of energy integrals is used and inequalities of the type are derived on the given functions that are in the boundary condition. It is shown that the homogeneous problem corresponding to the original problem, under the conditions of the uniqueness theorem, has only a trivial solution in the entire considered domain. From which we can conclude that the original problem has only a single solution. If the obtained conditions for the given functions are violated, the problem posed does not have a unique solution. When investigating the question of the existence of a solution to the problem posed, a system of two equations is considered, consisting of the basic functional relations between the trace of the desired function and the traces of the derivative of the desired function, brought to the line of degeneration y = 0. Eliminating from the system the function τ (x) - the trace of the desired solution on the line of degeneration, we arrive at an equation for the trace of the derivative of the desired function. Under the condition of the existence and uniqueness theorem, the problem posed is equivalently reduced to the Fredholm integral equation of the second kind, the unconditional solvability of which follows from the uniqueness of the solution to the problem posed.

Abstract In this paper, we study the initial boundary problem of fifth-order Korteweg-de Vries equation with nonlinear boundary values. First, we establish a so-called sharp boundary trace regularity associated with the linearized fifth-order Korteweg-de Vries equation. Then, aided by the sharp boundary trace regularity, we verify that initial-boundary value problem of fifth-order Korteweg-de Vries equation with nonlinear boundary conditions is locally well-posed when initial and boundary values are properly chosen.

JavaScript programming takes critical roles in developing web application systems. Unfortunately, JavaScript programming is not fully educated in most universities, although its study may not be easy for students since the code is usually made by special composing styles. To assist self-study of JavaScript programming, currently, we are developing JavaScript programming learning assistant system (JSPLAS) by extending our JPLAS works for Java programming. In JPLAS, the value trace problem (VTP) is offered for code reading study by novice students. A VTP instance consists of a source code and a set of questions, where each question asks the actual value of an important variable or an output message in the source code. The correctness of any answer is marked through string matching with the correct one. In this paper, we study the VTP for code reading study of JavaScript programming. We generate 57 instances using source codes on basic grammar concepts and confirm the effectiveness through applications to 45 university students in Myanmar and Japan.

Presently, C++ programming has been taught in many universities around the world as the first object-oriented programming language for undergraduate students to start studying programming concepts and computer architecture. However, many of them may struggle in studying C++ programming due to the nature in the formal language. Thus, hands-on self-study tools can be effective. In previous, we have developed Java programming learning assistant system (JPLAS) for assisting self-study of Java programming. JPLAS offers the value trace problem (VTP) for novice students to study Java programming through code reading study. In a VTP instance, actual values of important variable or standard output messages in a given source code are questioned, where the correctness of each answer is checked through string matching. In this paper, we investigate the effectiveness of VTP for hands-on self-study of C++ programming by novice students. We generated 37 VTP instances for basic grammar concepts using source codes in textbooks or websites for C++ programming, and asked 46 students in three universities in three countries to solve them using the answer interface for JPLAS. The results suggest that most of the students are satisfactory, but some students need cares at early programming study stage.

В статье предложена методика вычисления регуляризованного следа для дифференциального оператора с кусочно-гладким потенциалом и многоточечными граничными условиями. Весовая функция дифференциального оператора является разрывной. С помощью метода Наймарка на участках непрерывности потенциала и весовой функции при больших значениях спектрального параметра получена асимптотика решений дифференциальных уравнений, задающих изучаемый оператор. Полученная асимптотика решений позволяет изучить условия "сопряжения" в точке разрыва коэффициентов. Необходимость условий "сопряжения" следует из физических соображений. Изучаемые краевые задачи возникают при изучении колебаний стержней, балок и мостов, составленных из материалов различной плотности. Изучены многоточечные граничные условия, определяющие оператор. Успешно выполнена технически сложная часть исследования - изучена индикаторная диаграмма уравнения, корни которого являются собственными значениями оператора. Вычислена асимптотика собственных значений оператора. С помощью асимптотики собственных значений методом Лидского - Садовничего вычислен первый регуляризованный след дифференциального оператора.

Abstract. The problem to find an optimal distribution of elastic moduli within a given plane domain to make the compliance minimal under the condition of a prescribed value of the integral of the trace of the elastic moduli tensor is called the free material design with the trace constraint. The present paper shows that this problem can be reduced to a new problem of minimization of the integral of the stress tensor norm over stresses being statically admissible. The eigenstates and Kelvin’s moduli of the optimal Hooke tensor are determined by the stress state being the minimizer of this problem. This new problem can be directly treated numerically by using the Singular Value Decomposition (SVD) method to represent the statically admissible stress fields, along with any unconstrained optimization tool, e.g.: Conjugate Gradient (CG) or Variable Metric (VM) method in multidimensions.

For a second-order hyperbolic equation with inhomogeneity |u|m−1u, m > 1, a forward and an one-dimensional inverse problems are studied. The inverse problem is devoted to determining the coefficient under heterogeneity. As an additional information, the trace of the derivative with respect to x of the solution to the forward initial-boundary value problem is given at x = 0 on a finite interval. Conditions for the unique solvability of the forward problem are found. For the inverse problem a local existence and uniqueness theorems are established and a stability estimate of its solutions is found.

To assist Java programming educations, we have developed a Web-based Java Programming Learning Assistant System (JPLAS). JPLAS provides the element fill-in-blank problem to help novice students self-study Java programming by filling in blanked elements in a code. However, it is a pity that this problem can be solvable without reading the algorithm in the code, especially if students are familiar with grammar. In this paper, we propose the value trace problem to answer the changing values of important variables in a Java code that implements a fundamental data structure or algorithm , so as to improve the code reading capability. To verify the effectiveness, we generated five problems using Java codes for sorting and asked 10 students in our group to solve them.

AbstractIn “Risky choice framing: Task versions and a comparison of prospect theory and fuzzy-trace theory”, Kühberger and Tanner (2010) examined the impacts of removing stated zero/non-zero complements of risky options on the gain/loss framing effect. They also tested two rival theoretical explanations for this effect: prospect theory and fuzzy-trace theory. The present study aimed to examine the reliability and robustness of the evidence provided by Kühberger and Tanner by precise replication in Study 1. The original findings were reported for conditions in which the probability of the risky option was fixed, and the expected value of the two alternatives was approximately equivalent. The present study also aimed to examine the generality of their findings under additional conditions in which large, medium and small probabilities of the risky option were assigned, and the expected value of the certain or risky options differed. The main findings of Kühberger and Tanner (2010) were successfully replicated and confirmed under the original and additional conditions. The implications of these findings are discussed.

Banyak universitas di seluruh dunia mengajarkan pemrograman C sebagai bahasa komputer pengantar. Oleh karena itu, sangat penting bagi siswa pemula untuk terlibat dalam pembacaan ekstensif kode sumber C sederhana untuk memahami prinsip-prinsip pemrograman. Namun, ada kekurangan alat yang dirancang dengan baik untuk mendukung pembelajaran membaca kode secara mandiri di rumah. Sebelumnya, kami telah memperkenalkan konsep value trace problem (VTP) untuk pemrograman Java, di mana setiap contoh VTP terdiri dari kode sumber, beberapa pertanyaan, dan jawaban yang benar. (Klabnik & Nichols, 2023) Pertanyaan-pertanyaan ini menanyakan tentang nilai variabel kritis atau pesan keluaran dalam kode sumber, dengan respons siswa yang langsung divalidasi melalui pencocokan string untuk belajar mandiri. Dalam makalah ini, kami memperkenalkan VTP untuk belajar mandiri membaca kode dalam pemrograman C. Kami membuat 42 contoh VTP berdasarkan kode sumber C langsung yang mencakup konsep tata bahasa dasar dan struktur data fundamental serta algoritma yang ditemukan dalam buku teks dan sumber daya online. Selain itu, untuk contoh kasus yang menantang yang melibatkan pointer dan algoritme yang rumit, kami menyertakan petunjuk, pertanyaan pilihan ganda, dan referensi untuk meningkatkan akurasi solusi. Untuk menilai pendekatan kami, kami meminta 49 mahasiswa S1 dari Jepang, Cina, dan Myanmar untuk menyelesaikan contoh-contoh ini secara mandiri di rumah. Tingkat akurasi rata-rata mereka adalah 94,29%, dengan fitur-fitur pendukung kami yang meningkatkan akurasi sebesar 33,26% pada kasus-kasus yang sulit. Dengan demikian, proposal kami secara efektif mendorong pembelajaran mandiri dalam pemrograman C di kalangan siswa pemula. (Aho et al., 2023)

The effect of the creative problem solving model on problem solving ability and learning motivation in Geography subjects Geography learning is contextual and focuses on issues related to the life of the surrounding environment. Problem-solving abilities and low student learning motivation are problems in geography learning. This research aims to determine the influence of the creative problem-solving model on problem-solving abilities and learning motivation in geography subjects at Kepanjen Islamic High School. This type of research is a quasi-experiment with a pretest and posttest control group design covering classes X-2 and X-4, sampling using purposive sampling. The data analysis used is prerequisite testing and hypothesis testing. Hypothesis testing was used the MANOVA (Multivariate Analysis of Variance) Test. Based on the analysis results, the average score for the experimental class was higher than that of the control classes. The MANOVA test results show that the F value for Pillai’s trace, Wilks’ lambda, Hotelling’s trace, and Roy’s Largest Root have the same value, meaning that the null hypothesis (Ho) is rejected, and the alternative hypothesis (Ha) is accepted. The findings in this research are that the syntax of the creative problem-solving model, namely problem finding, idea finding, and solution finding, influences problem-solving abilities and learning motivation. The conclusion of this research shows a significant influence of the creative problem-solving learning model on the problem-solving abilities and learning motivation of students who are given treatment and those who use conventional learning models.

Краевые условия связывают след дробного интеграла от искомой вектор-функции на левом конце отрезка – в точке x=0, со следом самой вектор функции на правом конце отрезка – в точке x=l.

We study a nonlocal boundary value problem for a linear system of ordinary differential equations of fractional order with constant coefficients on the interval [0,l]. The fractional derivative of order α∈(0,1] is understood in the Riemann–Liouville sense. The boundary conditions connect the trace of the fractional integral of the desired vector function at the left end of the segment – at the x=0, with the trace of the vector function itself at the right end of the segment at the point x=l. The purpose of this work is to construct an explicit representation of the solution of this problem in terms of the Green’s function. The structure of the solution to the boundary value problem is investigated, the corresponding Green’s function is defined and constructed, and the representation of the solution is obtained. A theorem on the unique solvability of the boundary value problem under study is proved.

Abstract Simplification of execution traces is peculiarly important in the case of software comprehension. The objective is to make execution traces in ways that are more tractable and less difficult. However, the simplification process is a difficult task, particularly, in object-oriented contexts. Due to coupling, execution traces of object-oriented systems involve the Spaghetti Architectures phenomenon, which is a very complicated structure of dependencies. Therefore, the simplification process needs a well-established approach to be helpful for software comprehension. Otherwise, the simplified execution traces will be informative as their structures will involve several gaps that lead to a misunderstanding process. This research uses decoupling to guide the simplification of object-oriented execution traces. Specifically, decoupling truthfully can decrease the complexity of execution traces without eliminating the trace components and making numerous gaps in the trace structure. Then, decoupling can solve the problem of the Spaghetti Architectures phenomenon. A controlled experiment was conducted to empirically validate the usefulness and effectivity of the suggested work. There was a significant statistical added value demonstrated in the time required and the accurate solutions of the tasks being solved. More precisely, 25% less time required with a 62% more correct solutions were achieved solving the experiment’s comprehension tasks.

The solution of the initial boundary value problem for a system of two quasi-linear hyperbolic equations, which describes a rotationally symmetric vortex-free flow of a viscous incompressible fluid in an infinite cylindrical domain (pipe, blood vessel) is constructed. It is assumed that the side surface of the domain is a free (soft, compliant) boundary on which the kinematic condition is set. The dynamic condition at the boundary is modeled by some constitutive relation – the dependence of the pressure P on the cross-sectional area S of the cylindrical domain. To study the flow an asymptotic model based on the shallow water theory is used. When constructing the solution of the initial-boundary (as well as initial and boundary) problem for a system of two quasilinear partial differential equations of the first order, the hodograph method based on the conservation law is used. A variant of the polynomial constitutive relation is chosen for the study: P~S2β (β>0). In the case of the initial data problem which specified at the initial time the Riemann-Green function, allowing to construct an implicit analytical solution, and an algorithm (numerical) for constructing an explicit solution of the original problem are given. The main attention is focused on the special case P~S2, for which all the formulas necessary to construct a solution are written in explicit form. For P~S2, several variants of conditions (initial and boundary value) are considered for the initial boundary value problem, which allow us to trace the evolution of the solution in detail. Numerical calculations demonstrating the motion of shock waves and wave fronts are given. The results obtained, in practice, can be used to describe flows in blood vessels, as well as reliable tests for testing compu tational algorithms intended to solve such problems, in particular, systems of quasi-linear hyperbolic equations.

Full textAbstract:
In this qualitative study, the authors apply Callon’s sociology of translation to examine how new technology entrepreneurs enact material arguments that involve the first two moments of translation—problematization (defining a market problem) and interessement (defining a market and the firm’s relationship to it)—which in turn are represented in a claim, the value proposition. That emergent claim can then be represented and further changed during pitches. If accepted, it can then lead to the second two moments of translation: enrollment and mobilization. Drawing on written materials, observations, and interviews, we trace how these value propositions were iterated along three paths to better problematize and interesse, articulating a problem and market on which a business could plausibly be built. We conclude by discussing implications for understanding value propositions in entrepreneurship and, more broadly, using the sociology of translation to analyze emergent, material, consequential arguments.

The existence of a unique solution of the conjugation nonlocal problems in a rectangular domain for a third-order partial differential equation is proved, when for y > 0 the characteristic equation has 3 multiple roots, and for y < 0 it has 1 simple and 2 multiple roots. Using the Green’s functions and the method of integral equations, the solution of the problem is equivalently reduced to solving the boundary value problem for the trace of the desired function at y = 0, and then to solving the Fredholm integral equation of the 2nd kind, the solvability of which is proved by the method of successive approximations. The solution of the problem for y > 0 is constructed by the Green’s function method, and for y < 0 by reducing the problem to a two-dimensional Volterra integral equation of the 2nd kind.

The article analyzes the phenomenon of catharsis that occurs from the perception of the tragic in art. Based on the eudemonistic understanding of catharsis we trace the cultural and historical aspects of the problem and show that catharsis as an aesthetic and psychological phenomenon that emerged in antiquity in order to facilitate acceptance of the necessity of dying of Self for rebirth into a new life. Using the examples of expressionist paintings and their early origins (M. Grünewald, E. Munch, P. Picasso) we analyze catharsis that occurs in the process of the tragic artworks perception, showing its therapeutic value for the audience (accepting the inevitable and searching for meaning, struggling with despair, resisting chaos, evil, and destruction). We show that the tragic in art, including painting, creates an aesthetic space that penetrates the living space of the subject of artistic perception and creates the possibility of expanding the conceptual horizon and spiritual renewal.

Full textAbstract:
The theorem of the existence and uniqueness of the solution of the boundary value problem for the equation in partial derivatives of the fourth order with variable coefficients containing the product of the mixed parabolic-hyperbolic operator and the differential operator of the oscillation string with discontinuous conditions of gluing in the pentagon to the plane is proved. By the method of reducing the order of equations, the solvability of the boundary value problem is reduced to the solution of the Tricomi problem for the mixed parabola-hyperbolic equation with variable coefficients and discontinuous gluing conditions. Solving this problem is reduced to the solution of Fredholm’s integral equation of the second order relative to the trace of the derivative function on y along the line of variation of the equation type. In the hyperbolic part of the domain, the representation of the solution of the problem for the hyperbolic equation with the smallest terms was obtained by using the Riemann function method. In the parabolic part of the domain, the solution of the first boundary value problem for the parabolic equation with the smallest terms is obtained by the method of successive approximations and the Green’s function. As a result, the solution of the problem is realized by the method of solving the Gursa problem and the first boundary value problem for the equation of string oscillation.

In this paper, we study the initial boundary value problem for the isentropic Euler–Poisson system in an exterior domain with spherical symmetry. The initial data is supposed to be bounded and satisfy other suitable assumptions. Using a fractional step Godunov scheme, we construct the approximate solutions and prove the uniform [Formula: see text] estimates for the approximate solutions. Then the compensated compactness argument implies the convergence of the solutions. The weak entropy solution also satisfies the initial value and boundary value in the sense of trace.

The problems covered in the paper are inspired by the significant anniversary of one of the oldest higher educational institutions in Russia — Kazan (Volga Region) Federal University, which can be used as an example to trace the dramatic relationship between theology and science in the pre-revolutionary period of our history. Kazan Imperial University was an unusual educational institution in every sense of the word. In addition to purely educational and scientific, other functions were assigned to it. It still has a special mission today. This is a very difficult topic, and each historical epoch has offered its own answers to the interrelation of different worldviews. Relatively recently, theology and science were perceived as opposite, mutually exclusive cognitive systems. The authors look at the problem somewhat differently. Perhaps for the first time in Russian jurisprudence, teleology and theology are considered as sense-making factors in the development of law. And not by themselves, but in some connection. We are fully aware of the responsibility for such a statement of the issue. Nevertheless, the intellectual history of mankind provides certain grounds for such an unusual point of view for our science.

The ability to think critically and motivate students to learn in Islamic Religious Education (PAI) learning is one of the abilities students need to support them in solving problems in PAI lessons. Based on pre-research results, students' critical thinking skills and learning motivation are still low; apart from that, there is a lack of variety in the learning models used. To overcome this problem, researchers used the PBL learning model. This research aims to determine the effect of the PBL learning model on students' critical thinking abilities and learning motivation. This research is research (Quasi-Experimental Design). The sampling technique uses the Cluster Random Sampling technique. The sample in this research was class X (TKR) students as the experimental class and class X (TKJ) as the control class. The instruments used to collect data are tests and questionnaires. The data analysis techniques used are the normality test, homogeneity test, and hypothesis testing using the MANOVA test. Based on the MANOVA test, the values obtained from Pillai's Trace, Wilks' Lamda, Hotelling's Trace, Roy's Largest Root = 0.000, and α test criteria = 0.05, which means the p-value value is smaller than α test criteria, so H_0 is rejected. Thus, it can be concluded that the PBL learning model influences students' critical thinking abilities and learning motivation.

The problem of drinking water with high concentrations of trace metals is a major health concern in developing countries. Trace metal concentrations (Cd, Ni, Cu, Pb, and Fe) in water samples of different locations in Gezawa and Gabasawa Local Government were evaluated. The water samples used for the study were borehole water, sachet water, well water and river water and were collected from different geographical coordinates on the site i.e. Gezawa and Gabasawa Local Government in polythene plastic containers of 7liters capacity. The concentration levels of selected trace metals, (Cu, Cd, Fe, Ni, and Pb) were determined in water in (µg/L) using Microwave Plasma Atomic Emission Spectroscopy (MPAES). The highest mean concentrations (µg/L) of the trace metals in the water sources are Cd (0.12), Fe (43.38), Cu (2.64), Ni (0.527) and Pb (1.52). When the highest mean concentrations of trace metals in the water were considered, Iron has the highest mean concentration in the water with a concentration of 43.38 (µg/L) and cadmium had the lowest concentration with a value of 0.12 (µg/L). Comparison of these results showed that, their highest levels are within the standard values obtained in Nigeria and some developed countries.

The article is devoted to the issue of a systems approach in the context of philosophical problems. The necessity of revising system representations and expanding the dynamic component, according to the requirements of the time, is substantiated. Attention is focused on the evolution of the concept of the systems approach in Russian systemology. It is shown that the uniqueness of the evolution of the systems approach in Russia is due to the problem of determining its role and place in the conditions of the dominance of materialistic dialectics in the Soviet period. The aim of the article is to trace the modern formation of the synthesis of the systems approach and dialectics. Through historical analysis, the emergence of basic concepts on which system-dialectical synthesis is carried out today is revealed. Variants of interpretation of the systems approach in Russian science and philosophy are highlighted – its relationship with the philosophical principle of sistemicity, an interdisciplinary scientific field, and the field of private sciences. It is shown that the systems approach, enriched by the dynamic capabilities of the dialectic and synergetic approaches, is qualitatively expanding its application possibilities. The line of research raised by V. N. Sagatovskiy and continued by E. G. Vinogray is the problem of the causes of the formation of systems as a result of resolving systemic contradictions, complemented by the possibility of forming systems based on emerging synergistic relationships. It is proposed to consider the contradiction and synergy as a double category of system-forming factors in the process of formation of the modern concept of the systems approach.

Full textAbstract:
The problem of conjugation of two equations of hyperbolic type of the third order – the Haller equation in the positive part of the domain with an operator from the wave operator in the negative part – is investigated in the mixed domain. The problem consists in finding a regular solution of the equation under consideration when boundary conditions of the second kind are given on the positive part of the boundary of the region, and Cauchy conditions on one of the characteristics are given in the negative part. In addition, continuous gluing of the sought solution and its derivative on the conjugate line is required. A theorem on the existence of a single regular solution of the problem under study in the mixed domain is proved. To prove the single-valued solvability of the problem, we use the Tricomi method, according to which we obtain the corresponding fundamental relations between the traces of the desired solution and its derivative, transferred from the positive and negative parts of the mixed region to the conjugate line. From the obtained fundamental relations, we come to the second boundary value problem for an inhomogeneous ordinary differential equation of the second order with respect to the trace of the derivative of the desired solution, the solution of which is found and written out in explicit form. Then the solution of the investigated problem is written out in explicit form as the solution of the second boundary value problem for the Haller equation in the positive part of the mixed region and as the solution of the Darbu’s problem for the model equation of hyperbolic type of the third order in the negative part. Sufficient conditions on the given functions, providing regularity of the obtained solutions of the investigated problem in the mixed domain, are found.

The aim of our work is to give a well-posedness result for a boundary value problem of transmission-type for the nonlinear, generalized Darcy-Forchheimer-Brinkman and Stokes systems in complementary Lipschitz domains in R3. First, we introduce the Sobolev spaces in which we seek our solution, then we define the trace operators and conormal derivative operators that are involved in the boundary conditions of our treated problem. Next, we state a result that concerns the well-posedness of the transmission problem for the generalized Brinkman and Stokes system in complementary Lipschitz domains in R3. Afterwards, we state and prove an important lemma. Finally, we obtain our desired result by employing the well-posedness of the linearized version of our problem and Banach?s fixed point theorem.

Full textAbstract:
Resolution improvement always presents as the crucial task in geologic inversion. Band-limited characteristics of seismic data and noise make seismic inversion complicated. Specifically, geologic inversion suffers from the deficiency of low- and high-frequency components. We have developed the fixed-point seismic inversion method to alleviate these issues. The problem of solving the objective function is transformed into the problem of finding the fixed point of the objective function. Concretely, a recursive formula between seismic signal and reflection coefficient is established, which is characterized by good convergence and verified by model examples. The error between the model value and the inverted value is reduced to approximately zero after a few iterations. The model examples show that in either case, that is, the seismic traces are noise-free or with a little noise, the model value can almost be duplicated. Even if the seismic trace is accompanied by moderate noise, optimal inverted results can still be obtained with our method. The initial model constraint is further introduced into the objective function to increase the low-frequency component of the inverted results by adding prior information into the target function. The singular value decomposition method is applied to the inversion framework, thus making a high improvement of antinoise ability. Finally, the synthetic models and seismic data are investigated following our method. The inverted results obtained from the fixed-point seismic inversion are compared with those obtained from the conventional seismic inversion, and it is found that the former has a higher resolution than the latter.

The history of the formation of the concept of values in sociological science is shown, starting from the views of Wilhelm Dilthey, Herbert Spencer, Emile Durkheim and ending with the works of Maximilian Weber and Karl Marx. The review helps to trace how ideas about the content of values in scientific knowledge have changed. The authors of the article conducted a sociological study in order to consider the problems associated with determining the place of education in the value system of the younger generation. The article shows which aspects of education are attractive to modern young people, which, according to students, can be facilitated by obtaining a profession in a higher educational institution. It is concluded that education is important for modern youth, but actions by the state and society are necessary to eliminate negative trends, which were also identified during the sociological research.

Abstract. In this paper we present an Evolution Strategy (ES) approach towards the estimation of the location and strength of surface emissions of trace gases based on atmospheric concentration measurements and back-trajectory analyses. The details of the ES developed are outlined. The ES is tested using artificial emission maps at different grid resolutions and the results compared to those obtained on the same problems using Singular Value Decomposition (SVD). In almost all cases, the ES improves on SVD at equivalent resolutions. In addition, a number of insights, which the ES approach brings to the problem of source location and emission strength, are discussed, particularly the limitations on the use of measurement and meteorological data in the determination of emission source distribution.

As an emerging machine learning and information retrieval technique, the matrix completion has been successfully applied to solve many scientific applications, such as collaborative prediction in information retrieval, video completion in computer vision, \emph{etc}. The matrix completion is to recover a low-rank matrix with a fraction of its entries arbitrarily corrupted. Instead of solving the popularly used trace norm or nuclear norm based objective, we directly minimize the original formulations of trace norm and rank norm. We propose a novel Schatten $p$-Norm optimization framework that unifies different norm formulations. An efficient algorithm is derived to solve the new objective and followed by the rigorous theoretical proof on the convergence. The previous main solution strategy for this problem requires computing singular value decompositions - a task that requires increasingly cost as matrix sizes and rank increase. Our algorithm has closed form solution in each iteration, hence it converges fast. As a consequence, our algorithm has the capacity of solving large-scale matrix completion problems. Empirical studies on the recommendation system data sets demonstrate the promising performance of our new optimization framework and efficient algorithm.

The findings in the field indicate that the learning process currently occurring, particularly at Nurul Hikmah Mandung Bangkalan Junior High School, is still predominantly conducted through the presentation of verbal information. It is evident that the teachers at this institution continue to employ learning methods that are not optimal. A mere 30% of students utilize innovative learning methods, resulting in suboptimal learning outcomes. Of the 22 students, 15 (70%) scored below the KKM in PAI lessons. One method for engaging students in the learning process is to utilize a variety of learning models, including the Problem Based Learning (PBL) model (Riswati, Alpusari, Marhadi, 2018). The objective of this study is to assess the impact of PBL on student learning outcomes and critical thinking skills at Nurul Hikmah Mandung Kokop Bangkalan Junior High School. The research design employed in this study is quantitative. The results of the Pillai's Trace, Wilks' Lambda, Hotelling's Trace, and Roy's Largest Root tests yielded a significance value of 0.000, which is less than 0.05. This indicates that there is a statistically significant influence between the PBL learning model and critical thinking skills, as well as PAI learning outcomes, among students at Nurul Hikmah Mandung Kokop Bangkalan Junior High School.

Suppose that G is a reductive algebraic group defined over Q. There occurs in the trace formula a remarkable distribution on G(A)1 which is supported on the unipotent set. It is defined quite concretely in terms of a certain integral over G(Q)\G(A)1. Despite its explicit description, however, this distribution is not easily expressed locally, in terms of integrals on the groups G(QV). For many applications of the trace formula, it will be essential to do this. In the present paper we shall solve the problem up to some undetermined constants.The distribution, which we shall denote by Junip, was defined in [1] and [3] as one of a family {Jo} of distributions. It is the value at T = T0 of a certain polynomial . We shall recall the precise definition in Section 1.

Crowd sensing applications have demonstrated their usefulness in many real-life scenarios (e.g., air quality monitoring, traffic and noise monitoring). Preserving the privacy of crowd sensing app users is becoming increasingly important as the collected geo-located data may reveal sensitive information about these users (e.g., home, work places, political, religious, sexual preferences). In this context, a large variety of Location Privacy Protection Mechanisms (LPPMs) have been proposed. However, each LPPM comes with a given set of configuration parameters. The value of these parameters impacts not only the privacy level but also the utility of the resulting data. Choosing the right LPPM and the right configuration for reaching a satisfactory privacy vs. utility tradeoff is generally a difficult problem mobile app developers have to face. Solving this problem is commonly done by relying on a trusted proxy server to which raw geo-located traces are sent and privacy vs. utility assessment is performed enabling the selection of the best LPPM for each trace. In this paper we present EDEN, the first solution that selects automatically the best LPPM and its corresponding configuration without sending raw geo-located traces outside the user's device. We reach this objective by relying on a federated learning approach. The evaluation of EDEN on five real-world mobility datasets shows that EDEN outperforms state-of-the-art LPPMs reaching a better privacy vs. utility tradeoff.

Abstract Halal Product Guarantee is legal certainty regarding the halalness of a product as evidenced by a halal certificate. Regulations regarding halal certificates are carried out based on Law Number 33 of 2014 concerning Halal Product Assurance (“Law 33/2014”). This provision requires all products to have a halal certificate. This certificate is hoped to add the value of the product to be absorbed by the market more. However, the problem is that not all business actors or industries can implement halal guarantees. Micro, small, and medium enterprises (MSMEs) have weaknesses in the documentation and halal traceability. These two things become one of the criteria for the halal assurance system to get a halal certificate. We need a computerised information system that can help SMEs document and trace. Meanwhile, blockchain technology is needed for documentation transparency, which effectively keeps track of information and transactions. The system is proven to be safe and transparent. Because when the transaction takes place, all parties can see public access.
