"Pemetaan suatu citra gambar dari long range CCTV kepada koordinat nyata pada peta merupakan hal yang baru. Pengetahuan ini dapat digunakan dalam berbagai macam keperluan seperti : peletakan kamera CCTV pada ujung ? ujung daerah perkotaan untuk pendeteksian bencana (kebakaran, pencurian, dll). Pada penulisan laporan ini, penulis akan mencoba suatu metode pemetaan citra kepada koordinat nyata. Koordinat nyata tersebut bukanlah suatu koordinat x,y,z pada permukaan geografis melainkan koordinat pixel citra satelit yang mengambil gambar perkotaan tersebut. Input yang digunakan dalam metode ini adalah sudut pemotretan CCTV terhadap objek yang digunakan. Sudut yang dibentuk tersebut dapat berubah-ubah dan mengandung banyak ketidakpastian (uncertainty). Untuk mengatasi permasalahan tersebut maka penulis menggunakan logika fuzzy dalam memasukkan input sudut pemotretan. Sistem ini diujikan dengan data hasil simulasi percobaan. Pengembangan sistem ini dapat diarahkan kepada pemetaan pada permukaan geografis.
Image mapping from long range CCTV to real coordinate in map is an unordinary knowledge. This knowledge can be applied to many uses such as : set up a CCTV camera in the end of city to detect a disaster (fire, robbery, etc). In this final year project, the writer triesnto implement a new method to mapped an image from CCTV image to real coordinate. the real coordinate that is mentioned is not a X, Y, Z coordinate in land surface but pixel coordinate in satellite image that pictured the city. Angle that has been made between CCTV with the object is an input to the system. The problem is it is dynamic and has many uncertainty. To solved the problem, the writer use fuzzy logic within an angle. This system is tested with simulation data, it also can be developed to the land surface mapping."

"Tesis ini membahas tentang kemampuan mesin CNC Milling dalam menentukan titik sistem koordinat kerja Work Coordinate System melalui teknologi computer vision menggunakan OpenCV 2.4.13. Sistem bekerja dengan memberikan informasi posisi sudut benda kerja. Posisi didapat dari hasil seleksi images ROI region of interest. Hasil dari deteksi WCS yang disimpan dalam bentuk perintah gcode kemudian dijadikan insialisasi posisi pada mesin CNC Milling. Penelitian dilakukan melalui pemrograman C dengan algoritma 'Good Feature to Track' Shi-Tomasi dengan menggunakan kamera yang terpasang tegak lurus. Images yang berupa posisi koordinat benda kerja dapat digunakan untuk menentukan offset end-tool terhadap area kerja. Berdasarkan pengujian posisi WCS pada pergerakan sumbu x dan y posisi didapat rentang pergeseran adalah 0.3mm sampai 1.4mm dari posisi referensi WCS yang didapat dari kamera.

This thesis discusses the CNC Milling machine 39 s ability to determine the point of the work coordinate system Work Coordinate System by using the OpenCV 2.4.13 computer vision technology. The system works by providing information angular position of the workpiece. The position of the selection results obtained images ROI region of interest . Results of detection of WCS are stored in the form of orders Gcode then used initialize meachine position in CNC Milling. The study was conducted through the C programming algorithm Good Feature to Track Shi Tomasi using a camera mounted perpendicular. Images in the form of position coordinates of the workpiece can be used to determine the offset end tool against the work area. Based on testing WCS position on the movement of the x and y positions obtained shift range is 0.3mm to 1.4mm from the reference position WCS obtained from the camera."

"This book introduces a new generation of metrological systems and their application in a digital quality concept. It discusses the development of an optimal collision-free measuring path based on CAD geometry and tolerances defined in knowledge base and AI techniques such as engineering ontology, ACO and GA. This new approach, combining both geometric and metrological features, allows the following benefits: reduction of a preparation time based on the automatic generation of a measuring protocol; developed mathematical model for the distribution of measuring points and collision avoidance; the optimization of a measuring probe path; the analysis of a part placement based on the accessibility analysis and automatic configuration of measuring probes. The application of this new system is particularly useful in the inspection of complex prismatic parts with a large number of tolerances, in all of type production. The implementation is demonstrated using several case studies relating to high-tech industries and advanced, non-conventional processes."

"CarSim merupakan sebuah simulasi mengemudi driving simulator dimana menyediakan metode visualisasi performa mobil yang akurat, detail dan efisien. CarSim adalah perangkat lunak untuk menganalisis dinamika kendaraan, mengembangkan pengendali aktif, menghitung karakteristik kinerja mobil, dan rekayasa sistem keselamatan aktif generasi berikutnya. Selain itu dalam CarSim juga menyediakan bentuk jalanan path dan road yang dibuat seperti yang diinginkan dengan membangun bentuk jalanan dengan library yang disediakan oleh CarSim dimana terdapat segmen-segmen seperti library segment builder yang didefinisikan sebagai panjang dan lebar jalanan serta library line elevation reference untuk ketinggian. Selain itu pada path dan road CarSim dapat menentukan kekasaran friction dari jalanan tersebut. Hasil yang diharapkan dari percobaan ini adalah membuat jalanan mapping sesuai dengan sirkuit Prenois-Dijon sehingga dapat diterapkan dalam visualisasi path and road CarSim.

ABSTRAKA new algorithm is presented for evaluating the velocity field of the heat convection flow from a vertical solid flat plate using the temperature field. By using the coordinate transformation of Cartesian coordinates, to coordinates defined via streamlines, and visible in such coordinate approximations, it is possible to express the basic flow fields in terms of the temperature gradients only. After discretization, we formulate approximated sufficient finite difference formulas to evaluate the velocity field using the experimental data."

ABSTRAKSegitiga sama sisi yang memiliki koordinat titik sudut berupa bilangan bulat di mathbb R ^3 terletak di bidang ax by cz=0 yang memenuhi persamaan Diophantine a^2 b^2 c^2=3d^2 . Segitiga sama sisi dengan koordinat titik sudut berupa bilangan bulat juga dapat ditemukan di bidang hasil translasinya dengan vektor translasi yang elemen-elemennya bilangan bulat. Dengan mengetahui sifat tersebut, titik-titik sudut segitiga sama sisi yang berupa bilangan bulat ini dapat dinyatakan dalam bentuk persamaan parameter yang dikonstruksi.
ABSTRACTEquilateral triangles with integer coordinates vertices lie on plane ax by cz 0 where a,b,c satisfy Diophantine equation a 2 b 2 c 2 3d 2 for an integer d . If the plane is translated with any integer translation vector, we find planes which also containing equilateral triangles with integer coordinates vertices. Based on that knowledge and some previous studies, parametric equations for integer coordinates vertices of equilateral triangle in mathbb R 3 are constructed."

"This is the fifth and revised edition of a well-received textbook that aims at bridging the gap between the engineering course of tensor algebra on the one hand and the mathematical course of classical linear algebra on the other hand. In accordance with the contemporary way of scientific publication, a modern absolute tensor notation is preferred throughout. The book provides a comprehensible exposition of the fundamental mathematical concepts of tensor calculus and enriches the presented material with many illustrative examples. As such, this new edition also discusses such modern topics of solid mechanics as electro- and magnetoelasticity. In addition, the book also includes advanced chapters dealing with recent developments in the theory of isotropic and anisotropic tensor functions and their applications to continuum mechanics. Hence, this textbook addresses graduate students as well as scientists working in this field and in particular dealing with multi-physical problems. In each chapter numerous exercises are included, allowing for self-study and intense practice. Solutions to the exercises are also provided."
