"This book introduces concepts and technologies of Intelligent Transportation Systems (ITS). It describes state of the art safety communication protocol called Dedicated Short Range Communication (DSRC), currently being considered for adoption by the USDOT and automotive industry in the US. However, the principles of this book are applicable even if the underlying physical layer protocol of V2X changes in the future, e.g. V2X changes from DSRC to cellular-based connectivity.Fundamental ITS concepts include topics like global positioning system; Vehicle to Vehicle (V2V), Vehicle to Pedestrian (V2P), and Vehicle to Infrastructure (V2I) communications; human-machine interface; and security and privacy. Fundamental concepts are sometimes followed by the real-life test experimental results (such as in V2P Chapter) and description of the performance metrics used to evaluate the results. This book also describes equations and math used in the development of the individual parts of the system.This book surveys current and previous publications for trending research in the ITS domain. It also covers state of the art standards that are in place for the DSRC in the US, starting from the application layer defined in SAE J2735 all the way to physical layer defined in IEEE 802.11.The authors provide a detailed discussion on what is needed to extend the current standards to accommodate future needs of the vehicle communications, such as needs for future autonomous vehicles. Programs and code examples accompany appropriate chapters, for example, after describing remote vehicle target classification function a pseudo code and description is provided. In addition, the book discusses current topics of the technology such as spectrum sharing, simulation, security, and privacy.The intended audience for this book includes engineering graduate students, automotive professionals/engineers, researchers and technology enthusiasts."

"ABSTRAK

Untuk menunjang pemantauan konsentrasi manusia, perlu adanya pemahaman mengenai respon sinyal dari EEG terhadap dua kondisi manusia ya itu saat sedang konsentrasi penuh dan konsentrasi tidak penuh (adanya distraksi). Dalam mengolah data sinyal EEG tersebut, dibutuhkan metode algoritma dan klasifikasi sinyal untuk mendapatkan hasil data sinyal dari dua kondisi tersebut. Pada penelitian ini akan dijelaskan tentang sistem perancangan pendeteksian konsentrasi manusia berdasarkan sinyal EEG. Metode yang digunakan adalah Fast Fourier Transform (FFT) dan Discrete Wavelet Transform (DWT) sedangkan dalam algoritma klasifikasinya menggunakan Support Vector Machine (SVM). Hasil yang telah didapatkan dalam pengujian ini adalah SVM lebih mampu untuk mengklasifikasikan sistem dengan kernel RBF menggunakan 30% holdout validation. Keakurasian dari sistem ini adalah 91% pada metode DWT dan 72% pada metode FFT. Sehingga, dari kedua ekstraksi metode FFT dan DWT, yang memiliki nilai ekstraksi terbaik adalah DWT.

ABSTRACTTo support the monitoring focused human concentration, there is a need to understand the response of signals from EEG in two conditions which are when human is in full concentration and less concentration (presence of distraction).  To process those EEG signal data, an algorithm method and classification is needed to get the results of signal data from these two conditions In this research, the system of detecting design of human concentration levels based on EEG signals will be explained. The used methods are Fast Fourier Transform (FFT) and Discrete Wavelet Transform (DWT) while the classification algorithm uses Support Vector Machine (SVM).  The result of this research shows that by using SVM, a much more reliable result is achieved when a kernel RBF is used with 30% holdout validation. The result of the aforementioned method yields a 91% accuracy with DWT method and a 72% accuracy with FFT.

ABSTRACTThe growth of smartphone users have changed Indonesian society lifestyle towards digital, one of the strongest is to shop online. Some of the obstacles in e-commerce expansion in Indonesia has encourage the emergence of online-to-offline e-commerce platform mobile applications to tackle this barrier. Competition between the various types of e-commerce in Indonesia has made actors of e-commerce aggressively pursuing a strategy to attract the public to choose and use their e-commerce. User experience (UX) is a very important factor for an application to give a first impression about the company and products offered through the interaction between user and product. Effectiveness, efficiency, error, satisfaction, attractiveness, and visual appeal is the most influential UX dimensions in giving the perception to the user. This study aims to evaluate UX e-commerce platform mobile application by using performance metrics, self-reported metrics, behavioral metrics, and issue-based metrics approach that assess performance, perception, behavior, and filter out user feels as a result of the interaction with applications, and also reveal the effect of experience in using the application. Based on the evaluation, it was found in the dimensions of efficiency and visual appeal was significantly affect by experience factor, and the result indicate the user perception about the application was not good enough, especially on the interface design. Therefore, user interface (UI) redesign was developed using the principles of UI design and Activity Relationship Chart (ARC) by combining the UX elements that have been evaluated, in order to increase user attraction."
