This book is intended for: •Upper-level undergraduate and graduate students of vehicle engineering •Practicing engineers •Designers •Researchers •Educators




Noise, Vibration and Harshness of Electric and Hybrid Vehicles


Book Description

The noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is a critical feature for customers to assess the performance and quality of vehicles. NVH characteristics are higher among factors that customers use to judge the vehicle's quality.This book sets out to introduce the basic concepts, principles, and applications of the NVH development and refi nement of Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Fuel Cell Electric Vehicles. Each type comes with its own set of challenges.




Automotive Software Engineering


Book Description

Since the early seventies, the development of the automobile has been characterized by a steady increase in the deploymnet of onboard electronics systems and software. This trend continues unabated and is driven by rising end-user demands and increasingly stringent environmental requirements. Today, almost every function onboard the modern vehicle is electronically controlled or monitored. The software-based implementation of vehicle functions provides for unparalleled freedoms of concept and design. However, automobile development calls for the accommodation of contrasting prerequisites – such as higher demands on safety and reliability vs. lower cost ceilings, longer product life cycles vs. shorter development times – along with growing proliferation of model variants. Automotive Software Engineering has established its position at the center of these seemingly conflicting opposites. This book provides background basics as well as numerous suggestions, rare insights, and cases in point concerning those processes, methods, and tools that contribute to the surefooted mastery of the use of electronic systems and software in the contemporary automobile.

This conference has brought researchers, academicians and practitioners from the national and international institutions to discuss and sharing around the big theme which is “Innovation in Science and Technology for Sustainable Human Quality Development”. The ICoSTA2022 conference presents 4 distinguised keynote speakers with several expertation including of The Educational and Learning System, Prof. Dr. Syawal Gultom, M.Pd, Glass Technology and Materials Science, Prof. Dr. Jakrapong Kaewkhao, expert in the nuclear reactor technology there is Dr. Eng. Topan Setiadipura, S.Si., M.Si, M.Eng and expert in nanostructures for smart sensor devices held by Dr. Mati Horprathum from Thailand. In addition, presenters come from various Government and Private Universities, Institutions, Academy, and Schools. Some of them are researcher from The National Atomic Energy Agency, National Research and Innovation Agency, Institut Technology Bandung, Sriwijaya University, Indonesian Technology Institute, North Sumatera University, University of Surabaya, ITS, UGM, Udayana University, Brawijaya University, Jember University, UNRI, Nusa Cendana University, Widya Mandala Surabaya Catholic University, UPI, and several institutions. The additional information, there are 23 institutions including from national and international were interested and get involved in this conference. Besides that, there are 86 papers received by committee, some of which are presented orally in parallel sessions, and others are presented through abstract. The articles have been reviewed with double blind review before accepted and published by EAI publisher. Grateful thanks to Director and Vice Directors and especially for Rector of Unimed who always coordinate the organizing committee, and the team who keeps cooperating in running this conference. We strongly believe that the ICoSTA-2022 conference provides a good forum for all researcher, academician and practitioners to discuss all science and technology aspects that are relevant to sustainable human quality development. We also expect that the future ICoSTA conference will be as successful and stimulating, as indicated by the contributions presented in this volume.




Estimating Spoken Dialog System Quality with User Models


Book Description

Spoken dialog systems have the potential to offer highly intuitive user interfaces, as they allow systems to be controlled using natural language. However, the complexity inherent in natural language dialogs means that careful testing of the system must be carried out from the very beginning of the design process. This book examines how user models can be used to support such early evaluations in two ways: by running simulations of dialogs, and by estimating the quality judgments of users. First, a design environment supporting the creation of dialog flows, the simulation of dialogs, and the analysis of the simulated data is proposed. How the quality of user simulations may be quantified with respect to their suitability for both formative and summative evaluation is then discussed. The remainder of the book is dedicated to the problem of predicting quality judgments of users based on interaction data. New modeling approaches are presented, which process the dialogs as sequences, and which allow knowledge about the judgment behavior of users to be incorporated into predictions. All proposed methods are validated with example evaluation studies.

The Impact and Importance of Instructional Design in the Educational Landscape


Book Description

Instructional design is pivotal to the landscape of education. Shifts in the educational landscape require different approaches to meet different needs. While it is important to realize that education in modern society looks much different than decades ago, it is essential to understand that the basic components of instructional design have not changed. No matter the classroom, all learning must begin with clear goals and objectives, learning activities, and assessments. From there, instruction is designed using a number of models or instructional designs as a foundation to develop learning. The Impact and Importance of Instructional Design in the Educational Landscape provides relevant theoretical instructional design models and the latest research findings related to these models. Covering topics such as co-teaching, lesson planning and delivery, and universal design for learning (UDL), this premier reference source is an excellent resource for pre-service and in-service teachers, teacher educators, instructional technology professionals, library media specialists, educational administrators, instructional leaders, researchers, and academicians.
