Widely regarded as the standard text on EMC, this book provides all the key information needed to meet the requirements of the latest EMC Directive. Most importantly, it shows how to incorporate EMC ...principles into the product design process, avoiding cost and performance penalties, meeting the needs of specific standards and resulting in a better overall product. As well as covering the very latest legal requirements, the Fourth Edition has been thoroughly updated in line with the latest best practice in EMC compliance and product design. Coverage has been considerably expanded to include the R&TTE and Automotive EMC Directives, as well the military aerospace standards of DEF STAN 59-41 and DO160E. A new chapter on systems EMC is included, while short case studies demonstrate how EMC product design is put into practice. Electronic design engineers, compliance engineers, regulatory engineers, test engineers, EMC consultants, and managers responsible for product compliance and product design will benefit from this book.
The first molecular analysis of samples collected in southern Backa (Serbia)
confirmed the presence of aster yellows (16SrI) and stolbur phytoplasmas
(16SrXII) in insects belonging to the family ...Cicadellidae, as well as in
carrot plants where the insects were collected. A correct identification of
the phytoplasmas and their vectors is essential to arrange effective control
strategies to prevent diseases associated with phytoplasmas from spreading to
carrots and other vegetable crops. In order to enhance knowledge about insect
vectors of aster yellows and stolbur phytoplasmas in Serbia, Cicadellidae and
Cixiidae (Homoptera Auchenorrhyncha), the most common vectors of these
phytoplasmas, were monitored in southern Backa during 2008. Adults leaf- and
planthoppers were collected and identified at species level using standard
entomological methods, and tested for phytoplasma presence by means of
PCR/RFLP. A total of 13 insect species of Cicadellidae were identified, as
follows: a) three species of the subfamily Agallinae: Anaceratagallia ribauti
(Ossiannilsson), Anaceratagallia venosa (Fourcroy), and Anaceratagallia
laevis (Ribaut); b) seven species of the subfamily Deltocephalinae:
Psammotettix confinis (Dahlbom), Psammotettix striatus (Linnaues)
Psammottettix alienus (Dahlbom), Macrosteles sexnotatus (Fall?n), Ophiola
decumana (Kontkanen), Errastunus ocellaris Fall?n, and Scaphoideus titanus
Ball; c) three species of the subfamily Typhlocibinae: Eupteryx atropunctata
(Goeze), Eupteryx mellissae Curtis, Zyginidia pullula (Boheman). Female
specimens of the genus Euscelis (Deltocephalinae) were also collected, as
well as one species of Reptalus quinquecostatus (Dufour) of the family
Cixiidae. Stolbur phytoplasmas were detected in A. laevis, A. ribauti, A.
venosa, P. striatus, P. confinis and P. alienus. The species: A. laevis, O.
decumana, and P. confinis were AY-infected (subgroup 16SrI-A), while subgroup
16SrI-C was found only in one specimen of P. confinis. Since some aster
yellows- and stolbur-infected species of the genera Psammotettix and
Anaceratagallia (especially P. confinis and A. laevis) were regularly and
commonly found in the infected carrot fields during the whole vegetative
period, they could play a significant role in transmitting and spreading
these pathogens in natural environment.
Prva molekularna istrazivanja uzoraka iz juzne Backe potvrdila su prisustvo
aster yellows (16SrI) i stolbur fitoplazmi (16SrXII) u insektima iz familija
Cicadellidae, kao i u biljkama sargarepe medju kojima su insekti sakupljani.
Tacna identifikacija vrsta fitoplazmi i njihovih vektora su osnov za
definisanje mera sprecavanja sirenja fitoplazmoza u usevima sargarepe i
drugog povrca. U cilju prosirenja saznanja o insektima vektorima aster
yellows i stolbur fitoplazmi, o kojima u Srbiji ima malo podataka, tokom
2008. godine nastavljeno je sa pracenjem insekata iz fam. Cicadellidae i fam.
Cixiidae (kao najcescih prenosilaca pomenutih vrsta fitoplazmi) u juznoj
Backoj. Standardnim entomoloskim postupcima sakupljana su imaga cikada,
identifikovana do nivoa vrste i testirana na prisustvo fitoplazmi PCR/RFLP
metodama. Identifikovano je ukupno 13 vrsta insekata iz familije
Cicadellidae, od cega a) tri vrste iz subfamilije Agallinae: Anaceratagallia
ribauti (Ossiannilsson), A. venosa (Fourcroy) i A. laevis; b) sedam vrsta iz
subfamilije Deltocephalinae: Psammotettix confinis (Dahlbom), P. striatus
(Linnaues), P. alienus (Dahlbom), Macrosteles sexnotatus (Fall?n), Ophiola
decumana (Kontkanen), Errastunus ocelaris Fall?n i Scaphoideus titanus Ball;
c) tri vrste iz subfamilije Typhlocibinae: Eupteryx atropunctata (Goeze),
Eupteryx mellissae Curtis, Zyginidia pullula (Boheman). Prikupljen je i
odredjen broj zenki iz roda Euscelis (Deltocephalinae), kao i jedna vrsta iz
fam. Cixiidae Reptalus quinquecostatus (Dufour). Prisustvo stolbur fitoplazmi
zabelezeno je u A. laevis, A. ribauti, A. venosa, P. striatus, P. confinis i
P. alienus. Vrste A. laevis, O. decumana i P. confinis bile su inficirane AY
(soj 16SrI-A), dok je soj 16SrI-C detektovan samo u jednoj jedinki P.
confinis. S obzirom da su tokom citavog vegetacionog perioda AY i STOL
zarazene vrste iz rodova Psammotettix i Anaceratagallia (pre svega P.
confinis i A. laevis) bile redovno i najcesce prisutne u zarazenim poljima
sargarepe, one mogu imati znacajnu ulogu u prenosenju i sirenju ovih patogena
u prirodi.

How may we characterize contemporary society in a world so complex? Can looking at the diverse paths followed by various cultures in the modern world generate useful new social scientific typologies, ...or must a different set of questions be posed in this era of globalization? What, in short, is the nature of modernity? These are some of the questions addressed by the contributors to Multiple Modernities.Following the theme in an earlier work edited by Shmuel Eisenstadt, Public Spheres and Collective Identities, this book challenges conventional notions of how the world has changed politically, socially, and economically. The authors consider the meaning of modernity in contexts as different as communist Russia, modern India, the Muslim world, Latin America, China and East Asia, and the United States. Miscegenation, transnational migration, technological developments, and changing communications have shifted the ground on which theories of society were once built; political system, diaspora groups, religion, and ""classical"" theories of modernity have to be reconsidered in a new context.Authors and chapters include: S.N. Eisenstadt, ""Multiple Modernities""; Bjrn Wittrock, ""Modernity: One, None, or Many? European Origins and Modernity as a Global Condition""; Johann P. Arnason, ""Communism and Modernity""; Nilfer Gle, ""Snapshots of Islamic Modernities""; Dale F. Eickelman, ""Island and the Languages of Modernity""; Sudipta Kaviraj, ""Modernity and Politics in India""; Stanley J. Tambiah, ""Transnational Movements, Diaspora, and Multiple Modernities""; Tu Weiming, ""Implications of the Jrise of 'Confucian' East Asia""; Jrgen Heideking, ""The Pattern of American Modernity from the Revolution to the Civil War""; and Renato Ortiz, ""From Incomplete Modernity to World Modernity.""Written in clear and non-technical language for both a scholarly and general audience, this volume confronts the problem of just what constitutes the common core of modernit
Coanda effect is used in several engineering applications with distinctive designs and structures. It is also applied in aircrafts flying at low speeds for a comfortable ride. In this paper, we have ...designed and modelled Coanda effect in terms of a flying saucer. The fabrication was done by means of structural and electronic components. Electrical motor was used as a propeller to take off and land vertically (VTOL) along with hovering capability. The rotor disc diameter is smaller than the bulbous body unlike a helicopter which makes to fly very stable. Control flaps were used to regulate the path by altering the flow over the streamlined body. The model was then tested with a remote control. Numerical Simulation of the tesla turbine was done using ANSYS 14.5 software and displacements were obtained by applying different forces on designed model. CATIA V5 was used to analyse the shaft of the model to get minimum value of torque at which the shaft starts to deform.
In STOL, it is a critical factor to maintain lifting force stably at low speed. For this purpose, a jet from the engine flows along the wing surface to create a large uptrend centrifugal force which ...yields an additional uplift force on the wing. In this research, numerical calculation using the Large Eddy Simulation method is performed to find out about this special characteristic of a jet under the influence of inertial forces. It is observed that the secondary flow appears within the jet and its vicinity. The pressure gradient normal to the wing surface, which creates the lift force, is increased by the addition of the jet. It is also observed that the jet center moves relatively to the reference frame adopted in the simulation, and the direction of the movement slightly deviates from the centrifugal force if the jet is swirling. At the initial time, the mean flow is distributed axisymmetrically, and it is shown that the inhomogeneous distribution of Coriolis force, which is due to the swirl, causes most part of the jet center's spanwise movement. In the course of time, however, the influence of advection in the plane perpendicular to the jet magnifies the spanwise movement.
This study addresses the design of an output-feedback H-infinity and fuzzy mixed controller for an advanced vertical and/or short take-off and landing aircraft that exhibits satisfactory global ...stability criteria. A fuzzy logic based optimization approach is employed to solve autonomously the constrained control allocation problem by suitably adjusting the components of the output vector and finding a proper vector in the attainable moment set. SiYuulations show that the designed fuzzy controller is better suited to resist external disturbances, and is robust against parameter perturbations.
