The movement of an electron around the atomic nucleus has today a great importance in many engineering fields. Electronics, aeronautics, micro and nanotechnology, electrical engineering, optics,... More > lasers, nuclear power, computing, equipment and automation, telecommunications, genetic engineering, bioengineering, special processing, modern welding, robotics, energy and electromagnetic wave field is today only a few of the many applications of electronic engineering. This first chapter presents shortly a new and original relation which calculates the radius with that the electron is running around the atomic nucleus. The second chapter presents, shortly, a new and original relation (20) which calculates the Doppler Effect exactly. The third chapter aims to disseminate new methods of obtaining energy.< Less
Industrial Design in Mechanical Engineering By Florian Ion PETRESCU, Relly Victoria PETRESCU
eBook (PDF): $5.61
Industrial Design in Mechanical Engineering is the first edition of a largest old preocupation of the authors in this field. It presents the design of the Otto Motors, kinematics and dynamics, a new... More > Otto engine, the efficiency of the engines with internal combustion, the design of the V engines, the design of the distribution mechanisms, the design of the power train and the design of the drivetrain. It presents as well the design of the planetary trains with their real efficiency. The book has 14 chapters. Last second deals with 3R and 4R design mechanisms. Since the predominant component in all chapters is dynamics, the book might be called and dynamic design in mechanical engineering.< Less
THE DESIGN OF GEARINGS WITH HIGH EFFICIENCY By Florian PETRESCU, Relly PETRESCU
eBook (PDF): $9.06
(1 Ratings)
Development and diversification of machines and mechanisms with applications in all areas of scientific research requires new systematization and improvement of existing mechanical systems by... More > creating new mechanisms adapted to the modern requirements; the gearing mechanisms are found today everywhere: in the industry of machinery construction, in energy industry, in aeronautics and aerospace, in electronics& Electrical, in oil industry, in mechatronics and robotics, etc. In this context this book attempts to bring a contribution to science and technology applied in the kinematic and dynamic analysis and synthesis of mechanisms with gearings. The book presents an original method to determine the efficiency of the gearing; the originality of this method relies on the eliminated friction modulus. With the relations presented in this paper, one can synthesize the gear’s mechanisms; the best efficiency can be obtained with the internal gearing when the drive wheel 1 is the ring.< Less
Near the flying time By Florian Ion PETRESCU, Relly Victoria PETRESCU
eBook (PDF): $15.14
The book shows the evolution the flight, from its inception until now. The USAF Project Office devoted to the Avro projects, recommended that the WS-606A and all related work (including the Avrocar)... More > be cancelled. A "stop/go" work order came down and Frost was forced once more to try and rescue the project. In an elaborate effort, Frost made a resounding case for continuation of US military funding. Late in May 1959, the USAF authorized Avro to continue the "flying saucer" programs (see the chapter 1). The United States Marine Corps began crew training for the Osprey in 2000, and fielded it in 2007; it is supplementing and will eventually replace their CH-46 Sea Knights. The Osprey's other operator, the U.S. Air Force fielded their version of the tiltrotor in 2009. Since entering service with the U.S. Marine Corps and Air Force, the Osprey has been deployed in both combat and rescue operations over Iraq, Afghanistan and Libya (see the chapter 4).< Less
TURN ON THE LIGHTS! By Florian PETRESCU
eBook (PDF): $17.37
Welcome! A Short Book Description: This book, try a vision about the tomorrow Earth's energies. Besides the traditional energies, are presented and possible new energies source. The author presents... More > shortly, the annihilation process, which can donate energies obtained by the annihilation process between a particle and its antiparticle. Practically it proposes obtaining energy by the process of annihilation of matter with the antimatter. Another proposed method is the acquiring energy from the source and retransmitting it on the Earth in concentrated form.< Less
Mechanical Systems, Serial and Parallel By Florian PETRESCU, Relly PETRESCU
eBook (PDF): $9.51

A Short Book Description This paper is a scientific view, uniform, general, comprehensive and unbiased of the main problems posed by mechanical systems, mobile, serial and parallel. It gives an... More > overview, followed by geometric and kinematic study of the serial and parallel structures. It continues with an introduction in the dynamics these systems. At the serial systems are studied both direct and indirect kinematics, while at the parallel systems is studied only indirect kinematics (this being more useful). Presentation is closely linked of the basic methods of calculating the matrix, which are introduced step by step for a easy understanding of the each sequence. The book is divided into 14 chapters, who have been based on our courses, prepared for our students of the next disciplines: mechatronics, industrial robots, manipulators, automated welding, etc.. The paper is addressed equally to all specialists and to all future specialists which are working in these areas. The book is written in Romanian.< Less
