"Quaternion adalah sebuah konsep matematika yang merupakan perluasan dari bilangan kompleks dengan empat parameter. Quaternion dilambangkan dengan 𝑞, dan 𝑞=𝑞0+𝑞1𝑖+𝑞2𝑗+𝑞3𝑘,𝑞0,𝑞1,𝑞2,𝑞3∈𝑅. Banyak aplikasi dari quaternion yaitu pada aljabar, geometri, matriks, komputasi, kalkulus, dll. Quaternion mempunyai 4 elemen dasar yaitu {1, i, j, k} yang membentuk grup terhadap operasi perkalian. Quaternion dapat dipakai untuk mencari matriks standar dari rotasi vektor jika sumbu rotasinya bukan sumbu koordinat, tetapi sembarang vektor satuan.

Quaternion is a mathematical concept that is an extension of the complex numbers with four parameter. Quaternion is denoted by q and q =𝑞0+𝑞1𝑖+𝑞2𝑗+𝑞3𝑘, 𝑞0,𝑞1,𝑞2,𝑞3∈𝑅 There are many application of quaternion, they are on algebra, matrices, computing, calculus, etc. Quaternion has 4 basic element, they are 1,𝑖,𝑗,𝑘 that form the group on multiplication operation. Quaternion is used to find the standard matrix of the rotation vector if the rotational axis is not the coordinate axis, but any vector."

"This book presents a new approach for the analysis of chaotic behavior in non-linear dynamical systems, in which output can be represented in quaternion parametrization. It offers a new family of methods for the analysis of chaos in the quaternion domain along with extensive numerical experiments performed on human motion data and artificial data. All methods and algorithms are designed to allow detection of deterministic chaos behavior in quaternion data representing the rotation of a body in 3D space. This book is an excellent reference for engineers, researchers, and postgraduate students conducting research on human gait analysis, healthcare informatics, dynamical systems with deterministic chaos or time series analysis."

"Pergerakan robot dalam pertunjukan atau pameran robot seringkali terlihat tidak alami karena robot harus dikendalikan dengan tombol dari perangkat tertentu, misalkan joystick dan papan tombol. Dalam penelitian ini akan dibahas perancangan pergerakan robot berdasarkan pergerakan tangan manusia menggunakan sensor Myo Armband. Pergerakan robot yang disesuaikan dengan pergerakan tangan akan membuat kesan robot digerakkan secara alami. Penelitian ini menggunakan nilai IMU yang mewakili posisi tangan dan nilai EMG yang selanjutnya dikonversikan ke postur tangan untuk menggerakkan robot. Pengolah data yang digunakan adalah Arduino Mega yang tehubung dengan Myo Armband dengan koneksi Bluetooth dan terhubung ke robot dengan menggunakan modul 32-channel servo controller. Hal ini menjadi suatu kelebihan dalam rancang bangun karena tidak dibutuhkan perantara berupa PC atau smartphone untuk pengambilan data. Dari rancang bangun yang sudah dibuat, didapat hasil bahwa robot dapat bergerak sesuai dengan perintah hasil olahan data pergerakan tangan. Robot dapat digerakkan ke posisi dasar (atas, bawah, tengah, kiri, kanan) dan dikombinasikan dengan postur tangan untuk menggerakkan penggenggam ke posisi mengunci dan melepas benda. Melalui kombinasi ini juga robot digerakkan melalui pergerakan pada sumbu kartesian (task-space) dan pergerakan sudut masing-masing servo (joint-space).

The movement of robots in a robot show or exhibition often looks unnatural because the robot must be controlled with buttons from certain devices, for example joysticks and keyboards. In this study we will discuss the design of robot movements based on human hand movements using the Myo Armband sensor. The movement of the robot that is adjusted to the movement of the hand will make the impression of the robot being moved naturally.

This study uses the IMU value that represents the hand position and the EMG value which is then converted to the hand posture to move the robot. The data processor used is Arduino Mega which connects with Myo Armband with a Bluetooth connection and is connected to a robot using a 32-channel servo controller module. This becomes an advantage in the design of the build because it is not needed an intermediary in the form of a PC or smartphone for data retrieval.

From the design that has been made, the results obtained that the robot can move in accordance with the command processed by hand movement data. Robots can be moved to the basic position (up, down, center, left, right) and combined with hand postures to move the gripper to the position of locking and releasing objects. Through this combination, robots are also moved through movement on the cartesian axis (task space) and the angular movement of each servo (joint space)."

"This open access book presents theoretical framework and sample applications of variant construction. The first part includes the components variant logic, variant measurements, and variant maps, while the second part covers sample applications such as variation with functions, variant stream ciphers, quantum interference, classical/quantum random sequences, whole DNA sequences, and multiple-valued pulse sequences.Addressing topics ranging from logic and measuring foundation to typical applications and including various illustrated maps, it is a valuable guide for theoretical researchers in discrete mathematics; computing, quantum- and communication scientists; big data engineers; as well as graduate and upper undergraduate students."
