Book Description
I joined NEC in 1968 and was assigned to the circuit development department of the computer division. My first work was the circuit design of the switching mode power supply (SMPS) for the mainframe of the computer system. My job area was expanded to development of the design rule and to standardization of all over the electric and electronics parts for the non-logic circuit. Non-logic circuit was categorized to except the gate-array which forms the logic circuit of the mainframe. The experiment of SMPS was considered to be dangerousness and no one wanted to design. Therefore, my development of the power supply system (PSS) including the circuit design of SMPS was continued. The electric current of the mainframe and the supercomputer was reached to several thousand amperes. The critical problem of PSS was the heat dissipation and the electromagnetic interference (EMI) against the logic circuit. In 1992, the full-scale R&D of EMC became necessary hastily. I was nominated and transferred to the chief managing researcher of the established EMC engineering center in NEC Laboratories. I had believed that the switching mode circuit (SMC) including the digital circuit and SMPS circuit will be improved greatly if the EMC problem is solved. However the deep R&D was difficult because the actual fruits in every year were required strongly. Therefore, his knowledge of the science concerning EMC was not deepened enough. However I could understand the actual status of technologies of the electronics and electrics widely and the basic knowledge about how to approach the science as well as R&D could be learned. During this time, I completed PhD course and received the PhD. degree from Kyushu University, lectured in Kyushu University and Tohoku University for one year each, and executed several national projects by the cooperation of his colleague in NEC and of the supporters in the industrial society and academia. These are considered to be my best harvest in NEC Laboratories. I had decided to continue R&D for solving EMC problem of SMC after his retirement and to try the commercialization of the fruit of R&D. I established ICAST which is the abbreviation of the innovative circuit and system technologies in 2005. The solitary electromagnetic (SEMW) theory was advocated and the novel technologies including the low impedance lossy line (LILL) and the matched impedance lossy line (MILL) were invented based on the SEMW theory. Two purposes exist in this eBook. The first is to be validated the SEMW theory by the academia and the industrial society. The second is the contribution to the growth of the industry in the world by the technologies of LILL and MILL.

Blindsight
Author: Peter Watts
Publisher: Macmillan
ISBN: 1429955198
Category : Fiction
Languages : en
Pages : 388
Book Description
Hugo and Shirley Jackson award-winning Peter Watts stands on the cutting edge of hard SF with his acclaimed novel, Blindsight Two months since the stars fell... Two months of silence, while a world held its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Command Of The Air
Author: General Giulio Douhet
Publisher: Pickle Partners Publishing
ISBN: 1782898522
Category : History
Languages : en
Pages : 620
Book Description
In the pantheon of air power spokesmen, Giulio Douhet holds center stage. His writings, more often cited than perhaps actually read, appear as excerpts and aphorisms in the writings of numerous other air power spokesmen, advocates-and critics. Though a highly controversial figure, the very controversy that surrounds him offers to us a testimonial of the value and depth of his work, and the need for airmen today to become familiar with his thought. The progressive development of air power to the point where, today, it is more correct to refer to aerospace power has not outdated the notions of Douhet in the slightest In fact, in many ways, the kinds of technological capabilities that we enjoy as a global air power provider attest to the breadth of his vision. Douhet, together with Hugh “Boom” Trenchard of Great Britain and William “Billy” Mitchell of the United States, is justly recognized as one of the three great spokesmen of the early air power era. This reprint is offered in the spirit of continuing the dialogue that Douhet himself so perceptively began with the first edition of this book, published in 1921. Readers may well find much that they disagree with in this book, but also much that is of enduring value. The vital necessity of Douhet’s central vision-that command of the air is all important in modern warfare-has been proven throughout the history of wars in this century, from the fighting over the Somme to the air war over Kuwait and Iraq.

Fundamentals of Electric Propulsion
Author: Dan M. Goebel
Publisher: John Wiley & Sons
ISBN: 0470436263
Category : Technology & Engineering
Languages : en
Pages : 528
Book Description
Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.

Strengthening Forensic Science in the United States
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309142393
Category : Law
Languages : en
Pages : 348
Book Description
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
