"This work gives a broad introductory overview of the topic of usability. Firstly, usability is defined and a framework for identifying different aspects of usability is given. The main principles for creating usable designs are expounded, followed by practical advice as to how to design usable products. The book then tackles the issue of usability evaluation - a series of evaluation methods are described, followed by practical advice as to how to conduct the evaluation. The book draws on examples from software design and product design generally. This means whilst human-computer interaction HCI is a central issue in the book, other usability issues are also covered."

"Materials Science in Construction" explains the science behind the properties and behaviour of construction's most fundamental materials (metals, cement and concrete, polymers, timber, bricks and blocks, glass and plaster). In particular, the critical factors affecting in situ materials are examined, such as deterioration and the behaviour and durability of materials under performance. An accessible, easy-to-follow approach makes this book ideal for all diploma and undergraduate students on construction-related courses taking a module in construction materials. "

"This book addresses the need for basic information on aluminum alloys and their tempers. The author provides the reader with an understanding of the advantages and limitations of aluminum alloy and temper combinations in terms of the relationship of their composition, process history, and microstructure to service requirements. The temper designation of an aluminum alloy provides the user with background information as to how the alloy has been produced in order to obtain specific and desired properties and characteristics. Since aluminum alloys offer an excellent combination of light weight, high-strength, great corrosion resistance, and reasonable cost, they have become one of the most commonly used metal groups today.

"ABSTRACTPerkembangan teknologi yang semakin besar dan pemakaian smartphone yang meningkat saat ini menjadi peluang bagi organisasi untuk dimanfaatkan dalam dunia pembelajaran. Learning Management System hadir untuk membantu guru dan murid dapat berinteraksi secara real-time dan kebanyakan LMS berbentuk website. Evaluasi usability LMS berbasis smartphone dibutuhkan agar pengguna dapat menggunakan dengan mudah. Penelitian ini bertujuan untuk mendapatkan evaluasi usability LMS berbasis smartphone dengan kriteria efisiensi, efektivitas, satisfaction, dan eror sehingga diketahui faktor apa saja yang harus diperbaiki. Evaluasi dilakukan dengan memberikan skenario task sesuai dengan fitur yang ada di LMS Ruangguru, Quipper, dan Zenius. Metode yang digunakan meliputi performance measurement, Single Ease Question SEQ, kuesioner System Usability Scale SUS, dan Post-Study System Usability Questionnaire PSSUQ. Berdasarkan hasil penelitian secara keseluruhan, Zenius dan Ruangguru mempunyai nilai akhir SUS dan PSSUQ yang lebih tinggi dari Quipper. Pada kriteria efisiensi, responden lebih cepat menyelesaikan task dengan Zenius daripada Ruangguru dan Quipper. Tingkat kesuksesan Ruangguru dan Zenius lebih tinggi dari Quipper. Nilai lostness dan eror yang dihasilkan di Zenius lebih kecil daripada Ruangguru dan Quipper. Hasil penelitian ini adalah evaluasi dan komparasi usability yang dapat digunakan sebagai acuan perbaikan di masa yang akan datang.

ABSTRACTThe development of technology and the increasing use of smartphones are now an opportunity for organizations to be utilized in the learning world. Learning Management System is present to help teachers and students interact in real time and most LMS is a website. Usability evaluation of LMS based smartphone is required to help users use easily. This study aims to obtain evaluation of the usability of learning management system based smartphone with the criteria of efficiency, effectiveness, satisfaction, and error so it is known what factors should be improved. Evaluation is done by providing task scenarios according to the features in LMS Ruangguru, Quipper, and Zenius. The methods used include performance measurement, Single Ease Question SEQ, System Usability Scale SUS, and Post Study System Usability Questionnaire PSSUQ. Based on the results of the overall research, Zenius and Ruangguru have higher SUS and PSSUQs scores than Quipper. On efficiency criteria, respondents more quickly completed tasks with Zenius than Ruangguru and Quipper. Ruangguru and Zenius 39 s success rate is higher than Quipper. Lostness and number of error in Zenius is smaller than Ruangguru and Quipper. The results of this study are the evaluation and comparison of usability that can be used as reference future improvements."

"This book introduces Open Core Protocol (OCP) not as a conventional hardware communications protocol but as a meta-protocol: a means for describing and capturing the communications requirements of an IP core, and mapping them to a specific set of signals with known semantics. Readers will learn the capabilities of OCP as a semiconductor hardware interface specification that allows different System-On-Chip (SoC) cores to communicate. The OCP methodology presented enables intellectual property designers to design core interfaces in standard ways. This facilitates reusing OCP-compliant cores across multiple SoC designs which, in turn, drastically reduces design times, support costs, and overall cost for electronics/SoCs."
