Abstract:
Abstract Laying out a sampling transect in the field is a common task when researching natural systems and resources. With widespread availability of global navigation satellite systems (GNSS), such as the US global positioning system (GPS), it is becoming more common to resurvey legacy transects to establish them in globally referenced coordinate systems such as geodetic latitude/longitude or planimetric systems such as the Universal Transverse Mercator (UTM) or the State Plane Coordinate System (SPCS). Transforming local coordinates into a globally referenced coordinate system allows (1) disparate legacy surveys to be combined into a common geographic information system (GIS) database, (2) new GPS measurements to be incorporated into that same database, and (3) GPS-based navigation to be used for plot establishment and resampling. This article presents the mathematics necessary to determine the globally referenced planimetric coordinates of established linear, rectangular, or nominally rectangular transects (such as a rhombus) using formulas that are easily implemented on a spreadsheet. In addition, methods are given to determine the planimetric coordinates of new transects.

Abstract:
Inertial coordinate system and geodetic (terrestrial) coordinate system are used in processing of results of topographic survey, carried out with a mobile scanning complex. Mobile scanning complex geodetic coordinates, in turn, are presented in geodetic three-dimensional rectangular coordinate system form, in geodetic ellipsoidal coordinate system form and in the form of coordinates on a geodetic projection plane. The results of research, carried out earlier [4–7], suggest that the coordinate transformation on large areas distorts geodetic points coordinates. The article presents the results of similar investigations, but applied to a local area, limited by a mobile scanning complex surveying area. The accuracy of the mobile scanning complex coordinates is characterized by the mobile scanning complex coordinates errors cofactor matrix. It turned out that the local site sequential coordinate transformation procedure from one coordinate system to another coordinate system does not introduce any distortion into the mobile scanning complex coordinates.

Abstract:
The application of Polke's theorem in the search for a coordinate system for an electronic geometric model in the model space of a computer in 2D geometric modeling is considered. The possibility of creating an electronic geometric model in a system of axonometric axes in 2D modeling for scientific and educational purposes using a coordinate method is shown. It is possible to solve problems on axonometric coordinate planes that do not provide solutions in a rectangular coordinate system. In the computer model space, it has become possible to solve classical problems of descriptive geometry, the solution of which is associated only with the method of projecting space onto the projection plane. Secondary axonometry in the system of axonometric coordinate axes in 2D modeling has allowed us to solve a number of problems that do not have a solution in a rectangular coordinate system: • simulate the parallel (oblique) direction of the correspondence of two related shapes; • move the shape in space by rotating around the axonometric coordinate axes; • the construction of an arbitrary relationship of two affine corresponding figures with mutual perpendicularity of the axis of kinship and the direction of kinship; • switch to the coordinate solution method instead of projecting on the projection plane; • vased on the numerical equality of isometric coordinates with natural ones, it is possible to switch from one coordinate system to another right in the process of solving problems. A new reading of Polke's theorem expands the possibilities of the model space of personal computers for solving scientific and educational problems. However, a necessary condition for the implementation of these capabilities is the availability of isometric constructions by software. The possibility of learning how to create an electronic drawing from a full-scale part in the educational process is shown. In this case, it is advisable to use an isometric image as an electronic model, as it has visibility in a single-picture view and simplicity of drawing in a coordinate way. According to the constructed axonometric view, rectangular views are programmatically obtained using rectangular coordinates. A rectangular electronic drawing is formed from these types. If the purpose of its creation is to build a 3D geometric model of an object, then the construction can be continued, considering the created electronic drawing as the initial conditions for building a 3D model of the object

Abstract:
In PMU-based state estimation, a linear measurement model with phasors of both state variables and measurements expressed in rectangular coordinates has proven efficiency. The rectangular coordinate formulation is also used in optimal PMU placement problem aimed at providing the power system state estimation with the most informative measurements. In this case, it is assumed that the linearity of the measurement model ensures the optimality of the found placement of PMUs for any steady-state operating condition of the power system. The results presented in this paper show that this is not the case.

This study aimed to establish the coordinate transformation between the off-axis aspherics coordinate system σ and the axial symmetry aspherics coordinate system σ by transforming coordinates and present the computation models of asphericity in rectangular coordinate system and cylindrical coordinate system respectively. The asphericity expressions in both coordinate systems were applicable to the comparative sphere calculation of Off-axis aspherics with different figures. We selected an Initiation sphere in view of technology, along with equations in a right coordinate system for certain caliber and structure. Then, by numerical computation, we selected the best fitting sphere and simplifed the complex models by choosing a right coordinate system. At last, the solution for asphericity and the best fitting sphere curvature radius of off-axis aspherics were introduced by examples.

Abstract:
The method of the geopotential parameters determination with the use of the gradiometry data is considered. The second derivative of the gravitational potential in the correction equation on the rectangular coordinates x, y, z is used as a measured variable. For the calculated value of the measured quantity required for the formation of a free member of the correction equation, the the Cunningham polynomials were used. We give algorithms for computing the second derivatives of the Cunningham polynomials on rectangular coordinates x, y, z, which allow to calculate the second derivatives of the geopotential at the rectangular coordinates x, y, z.Then we convert derivatives obtained from the Cartesian coordinate system in the coordinate system of the gradiometer, which allow to calculate the free term of the correction equation. Afterwards the correction equation coefficients are calculated by differentiating the formula for calculating the second derivative of the gravitational potential on the rectangular coordinates x, y, z. The result is a coefficient matrix of the correction equations and corrections vector of the free members of equations for each component of the tensor of the geopotential. As the number of conditional equations is much more than the number of the specified parameters, we go to the drawing up of the system of normal equations, from which solutions we determine the required corrections to the harmonic coefficients.

Abstract:
This is the sixth one in a series of articles describing the technology of determining the Earth’s gravitational field parameters through gradiometric measurements performed with an onboard satellite electrostatic gradiometer. It provides formulas for calculating the components of the gravitational potential tensor in a geocentric spatial rectangular earth coordinate system in order to convert them into a gradiometric one and obtain a free term for the equations of correcting gradiometric measurements when determining the parameters of the Earth’s gravitational field. The components of the gravitational gradient tensor are functions of test masses accelerations measured by accelerometers and relate to the gradiometer coordinate system, while the desired parameters of the Earth’s gravitational field model relate to the Earth’s coordinate one. The components of the gravitational gradient tensor are the second derivatives of the gravitational potential in rectangular coordinates. The calculated values of the gravitational potential tensor components in the earth’s spatial rectangular coordinate system are obtained through double differentiation of the gravitational potential formula. Basing on the obtained formulas, an algorithm and a program in the Fortran algorithmic language were developed. Using this program, experimental calculations were performed, the results of which were compared with the data of the EGG_TRF_2 product.

Abstract:
Various transformations have found widespread use in applied geometry problems in simulating discrete frameworks of different surfaces with given properties. The paper presents a mathematical apparatus of active coordinate transformation, designed to solve problems of discrete geometric modeling. Under the active transformation of coordinates, the authors propose to consider a clear match between the points of the original and new coordinate systems, while maintaining their numerical correspondence, when the numerical values of the parameters of the original coordinate system will transition to the numerical values of the parameters of the new coordinate system. The paper describes the peculiarities of using active coordinate transformation. In the study is proposes to use the properties of the active plane transformation when switching from The work a rectangular Cartesian coordinate system to a rectangular cylindrical coordinate system for further modeling of discrete frameworks of curved surfaces. The authors of the article focus on that there are many discrete modeling methods among which the generalized static-geometric method of Professor Kovalev S.M. The work demonstrates the possibilities of this method by additional use of active coordinate transformation. It has been proved that the advantages and features of active transformation of coordinates can be used in providing the modeled surface with certain properties necessary for the designer or architect in the process of creating a particular modeled image. Using an active coordinate transformation will simplify the process of forming new geometric shapes of curved surfaces, which are quite difficult to describe analytically. The information presented in the work will be useful for architects and designers in the formation of discrete frames of various surfaces

Abstract:
碩士<br>國立臺中教育大學<br>教育資訊與測驗統計研究所<br>106<br>Computational thinking (CT) means skills for problem-solving using computers. It is a very crucial competency for the 21st citizen. Hence, in the “Draft Computer and Information Technology Curriculum in Twelve-Year National Fundamental Education,” CT plays an important role and will be taught in Junior and Senior high schools, Taiwan. CT includes abstraction, modeling, recursion, optimization, etc which are also belonged to the mathematical thinking (MT). Hence, in this dissertation, we want to develop a mathematical lesson combined with CT, i.e., a lesson about "Computational Thinking × Mathematical Thinking." In most CT courses such as Maze course in Google Blockly Games, Code.org, etc, the block codes "Move Forward," "Turn Left," and "Turn Right" are typically used to teach in the beginning. The course is highly related to the mathematical plane rectangular coordinate system in the Grade 1-9 Curriculum Guidelines for Mathematics. Moreover, it is a part of the spatial reasoning in MT. Therefore, we created a website, "Computational Thinking × Mathematical Thinking," and there are three units, "Step by Step," "Adventure Maze," and "Mathematical Application" for the mathematical plane rectangular coordinate system lesson combined with CT. In "Step by Step" unit, the "move forward" block code is used to introduce coordinates. Four block codes "x+1," "x-1," "y+1," and "y-1" instead of block codes, "Move Forward," "Turn Left," and "Turn Right" are created in the second unit, "Adventure Maze." Finally, the "Loops" and "Conditions" will be used to find the rest coordinate of a triangle with a known area and other two coordinates in the unit, "Mathematical Application." Forty-five students from a Taiwanese junior high school, Xinzhu, were participated in one hour "Computational Thinking x Mathematical Thinking" lesson. In the experiments, we compared the post-test scores and pre-test scores in CT and mathematical ability (MA), which is included MT and learning performance of the mathematical unit. According to the paired t-test, the experimental results show that the students' CT ability and MT are improved. However, only CT ability has a statistically significant difference for overall students. For MA, there is no significant difference. Students were regrouped into high and low learning performance groups according to the pre-test scores in MA. Students in low learning performance group could actually improve their MA through the concept of CT. The difference is statistically significant. Through feedback questionnaire analysis, found that students generally like the "Computational Thinking × Mathematics Education" course website, and give positive affirmation, that this teaching method is novel and interesting, and hope to develop a more diversified curriculum in the future.

Abstract:
Differential privacy technology has been widely used in the issue of trajectory data release. Improving the availability of data release under the premise of ensuring privacy and security is one of its basic research goals. At present, most trajectory data release methods use a rectangular coordinate system to represent location information. Research has shown that the availability of published data cannot be optimized through the rectangular coordinate system. In order to improve the effect of trajectory data release, this paper proposes a differential privacy trajectory data protection algorithm based on polar coordinates. First, the stay point detection method is used to find frequent stay points in the trajectory and the key location points related to personal privacy are detected by the type of location points. Then, this paper converts the rectangular coordinate system representation of the key position points to the polar coordinate system representation, and implement differential privacy trajectory data release by adding noise to the key position points represented by the polar coordinates. Experiments show that the algorithm proposed in this paper effectively improves the usability of trajectory data on real data sets.

Abstract:
Abstract Complex numbers first appeared in the early 17th century as a way of expressing the •impossible’ roots of an algebraic equation with real coefficients with the help of the ‘imaginary’ square root i of - 1. The representation of a complex number a+ ib by the point of the Euclidean plane with coordinates (a, b) in a rectangular cartesian coordinate system. known to us as the Argand diagram, appeared at the end of the 18th century, and was of vital importance to the development of the theory of functions of a complex variable which took place in the 19th century. Although the word ‘imaginary’ persists in the terminology of’real part’ and ‘imaginary part’, complex numbers ceased to be mysterious, and as more confidence was gained in handling them it was possible not only to use the Argand representation in reverse, as a way of assigning a complex coordinate to each point of the Euclidean plane, but also to think of extending the notion of complex numbers to ‘hyper•complex’ numbers which would serve a similar purpose in Euclidean space of higher dimension. It is these developments which concern us here.

An optical system using rectangular-to-polar coordinate transformation can be used for rotation invariant pattern recognition and classification. We have constructed an optical device to accomplish the coordinate transformation. The output of this device is imaged onto a liquid crystal light valve and Fourier transformed, then sent to a neural network and compared to stored invariant values. The coordinate transformation system uses a nonregular sampling array to minimize effects caused by the nonregular sampling resulting from a rectangular to polar transformation.

Full text
Abstract:
For the laminated piezoelectric rectangular plate with large deflection and large rotation, the nonlinear equilibrium differential equations are derived and solved. Firstly, the global Cartesian coordinate system to describe the undeformed geometry and the local orthogonal curvilinear coordinate system to describe the deformed geometry are established respectively on the mid-plane of the plate before and after the deformation, and the relationship between the two coordinates is expressed by transformation matrix. For the convenience of calculation, the expressions of the nonlinear curvatures and inplane strains are obtained by Taylor series expansion. Considering the piezoelectric effect, three equilibrium partial differential equations describing nonlinear bending problems are obtained by the principle of virtual work. Furthermore, in order to simplify the solution process, the stress function is introduced to automatically satisfy the first two equations for the large deformation of the cantilever plate, and the relationship between stress function, the mid-plane internal force and shear force is also given for the first time. Therefore, the stress function and the transversal displacement are the main unknowns of the governing equation and compatibility equation. Additionally, the approximate deflection function and stress function are given which can satisfy all the displacement boundary conditions and only part of the force boundary conditions. Thereby, the generalized Galerkin method is used to obtain the approximate solution of the nonlinear bending problem. Finally, the results in the study are verified by comparison with the results obtained from the finite element method. It also provides a theoretical basis for the engineering application of the large deformation of the piezoelectric cantilever plate.
