The book starts with an introduction to motion, relative motion, observer and frame of reference, state of absolute rest and state of absolute motion. The difference between the inertial frame of reference and non-inertial frame of reference has been discussed. The Galilean transformation equations are derived for the space-time observations taken from inertial frames moving with nonrelativistic relative speed. Consequently, the invariance in acceleration, length invariance and time interval invariance (space and time invariance) on the basis of Galilean transformation equations are proved. The concept of luminiferous ether medium as an absolute frame has been discussed only in which the observations for the state of absolute motion and state of absolute rest can be taken. The assumptions for the ether medium have been mentioned. Then the famous Michelson-Morley experiment was studied in detail to prove the ether medium and ether drag. The negative result of this experiment and conclusions from it are given. Principles and postulates of the special theory of relativity are discussed. Lorentz transformation equations are derived for the space-time observations taken from inertial frames moving with relativistic relative speed. The equations for time dilation and length contraction are derived using the Lorentz transformations and the simultaneity of event also has been discussed using these transformations. The variation of mass with velocity (relativistic mass) has been derived using the velocity addition theorem. At the end of this book, the study on Einstein’s famous mass-energy relation, the relation between relativistic energy and relativistic momentum, and the particle of zero rest mass has been given.

The speed of processes and the amount of data to be used in defending the cyber space cannot be handled by humans without considerable automation. However, it is difficult to develop software with conventional fixed algorithms (hard-wired logic on decision making level) for effectively defending against the dynamically evolving attacks in networks. This situation can be handled by applying methods of artificial intelligence that provide flexibility and learning capability to software. This paper presents a brief survey of artificial intelligence applications in cyber defense (CD), and analyzes the prospects of enhancing the cyber defense capabilities by means of increasing the intelligence of the defense systems. After surveying the papers available about artificial intelligence applications in CD, we can conclude that useful applications already exist. They belong, first of all, to applications of artificial neural nets in perimeter defense and some other CD areas. From the other side – it has become obvious that many CD problems can be solved successfully only when methods of artificial intelligence are being used. For example, wide knowledge usage is necessary in decision making, and intelligent decision support is one of yet unsolved problems in CD. Keywords: applied artificial intelligence; intelligent cyber defense methods; neural nets in cyber defense; expert systems in cyber defense. .

Resumo:O Atendimento Educacional Especializado (AEE), em parceria com as escolas públicas, objetiva complementar a aprendizagem de alunos com deficiência, no contraturno da escola comum. Esta pesquisa objetivou descrever e analisar o conteúdo dos encaminhamentos dos professores das escolas públicas para o AEE, categorizando-o de acordo com o sexo, idade, diagnóstico de deficiência, problemas de comportamento externalizante e internalizante, dificuldade de aprendizagem e outros. Para tal contatou-se uma instituição que oferece o AEE em um município do interior paulista e foram analisados 92 encaminhamentos de crianças do ensino infantil. Os resultados demostram que a maior parte dos atendimentos realizados pelo AEE destina-se a crianças que não possuem diagnóstico de deficiência. Além disso, 69% das queixas referem-se a problemas de comportamento externalizantes. A partir de tais dados discute-se sobre práticas educativas de professores e alternativas de atendimento para alunos com o...

L’objectif que cette étude s'est donné est de retracer dans quelle mesure, pour une ville provinciale comme Alep, les réformes du droit commercial durant l’ère du Tanzimat ont mis du temps avant de pouvoir vraiment s’accomplir. Elle tâche ainsi d'identifier à quels principaux problèmes les commerçants – ottomans et non ottomans – étaient confrontés dans les années menant à l’introduction du premier tribunal de commerce ottoman dans les années 1850, comment l’établissement d’un tel tribunal était perçu et quel fut le succès de cette institution à ses débuts. L'attention n'est pas fixée sur le plan théorique des lois et codes adoptés, mais avant tout sur la pratique du commerce, sur la mise en oeuvre des réformes et sur la façon dont les changements ont été vécus par les commerçants eux-mêmes.

Blended learning, defined as a combination of traditional face-to-face learning with technology based or online learning, has become one of the most popular approaches for teaching and learning (TnL) nowadays. This study by following the design and development research (DDR) approach highlights the content validity process in the development phase, which is one of the phases of the four phases of the DDR approach. The validation process involved six panels selected from among experts and instructors to evaluate the online content of Arabic blended learning course uploaded to the Moodle platform using the content validity index (CVI). The findings that were based on the content validity index from certain domains indicated that the developed online content was acceptable and validated with some suggestions for improvement by the selected panels. Once revisions were amended, the online platform can be opened to real users among students and instructors for the next phase; phases of im...

Permasalahan yang terjadi pada wilayah pesisir Pantai Tanjung Nipah meliputi mundurnya garis pantai, sedimentasi pada Muara Sungai dan kerusakan konstruksi bangunan pengaman pantai eksisting berupa jetty . Permasalahan tersebut diakibatkan tingginya gelombang. Penyusunan tugas akhir ini bertujuan untuk memodelkan dan merencanakan pengaman pantai yang tepat terhadap bahaya erosi dan pengendalian sedimentasi muara sungai di Pantai Tanjung Nipah. Wilayah pantai yang direncanakan yaitu sekitar 1,2 km termasuk area muara Sungai. Hasil analisis dari data angin yang diolah selama 23 tahun didapat angin dominan dari arah selatan dengan prosentase kejadian 29,43%. Tinggi gelombang pecah yang didapat dari gelombang representatif yaitu 0,6 m dan dari gelombang signifikan yaitu 2,1 m. Pengolahan data pasang surut menggunakan metode admiralty. Kemudian dilakukan pemodelan arus pantai dan pasang surut menggunakan aplikasi MIKE 21 Flow Model FM dan pemodelan perubahan garis pantai menggunakan apli...
