Plasma and Spot Phenomena in Electrical Arcs

Plasma and Spot Phenomena in Electrical Arcs

Isak Beilis

Springer Nature Switzerland AG
2020
sidottu
This book is devoted to a thorough investigation of the physics and applications of the vacuum arc – a highly-ionized metallic plasma source used in a number of applications – with emphasis on cathode spot phenomena and plasma formation. The goal is to understand the origins and behavior of the various complex and sometimes mysterious phenomena involved in arc formation, such as cathode spots, electrode vaporization, and near-electrode plasma formation. The book takes the reader from a model of dense cathode plasma based on charge-exchange ion-atom collisions through a kinetic approach to cathode vaporization and on to metal thermophysical properties of cathodes. This picture is further enhanced by an in-depth study of cathode jets and plasma acceleration, the effects of magnetic fields on cathode spot behavior, and electrical characteristics of arcs and cathode spot dynamics. The book also describes applications to space propulsion, thin film deposition, laser plasma generation, and magnetohydrodynamics, making this comprehensive and up-to-date volume a valuable resource for researchers in academia and industry.

Design of a Grid Connected Photovoltaic System for Institutional Use

Design of a Grid Connected Photovoltaic System for Institutional Use

A Photovoltaic power system is a system that uses light energy from the sun by converting it into electricity which might or might not be connected to the national grid. Solar radiation was collected by a Pyranometer installed at house rooftop in Otjomuise, Windhoek. The data was used to determine the size of photovoltaic generator required to produce electricity to meet the user demand. This project describes the steps followed while designing a PV system that will produce electricity for the University of Namibia (main campus) at a later stage. A 25.2 kWp grid connected PV system was designed and installed on Y-block rooftop, to meet the university daily energy demand and its annual energy output for the first year was estimated to be about 57.67 MWh.

Automation is a set of activities in which human work to manage and maintain equipment is replaced by the operation of automated devices.In conventional engineering, for one-shift work machining time is only 7%(610 hours) of the annual amount of time-8,760 hours. In flexible manufacturing systems(FMS), machining time reaches 75%(6,500 hours).Accuracy improvement shows to what extent the inaccuracy of a workpiece has decreased as a result of machining.A statistical method of estimating accuracy is based on the premises of probability theory and mathematical statistics.It determines the impact of the entire set of factors on the accuracy of machining.A statistical method is universal and can be used to investigate the accuracy of manufacture of workpieces or parts, assembly operations, quality control operations, etc.Tuning machine to a given processing accuracy is done under three basic methods.The first method.Tuning by trial passes and measurements.The second method.One or more tools can be tuned vis-a-vis a gauge or vis-a-vis the first usable part, vis-a-vis a template, or in special devices.The third method.The machine is tuned to process a batch of parts under a sampling met

Isak Saba (1875-1921) var lærer, politiker og folkeminnegransker født i Nesseby, Finnmark. Han var den første samiske stortingsrepresentanten og arbeidet hele livet for samenes sak. Saba gjorde en viktig innsats for å bevare og fremme samisk - særlig skoltesamisk - kultur. Han samlet inn sagn og eventyr i Varanger-området, og i denne boken blir de presentert for første gang for et allment publikum slik han selv skrev dem ned på sine samlerturer. Optegnelserer en parallellutgave med både norsk og samisk tekst, i den språkform fortellingene ble overlevert Saba tidlig på 1900-tallet og oversatt av ham selv. Innledning av Line Esborg, Norsk Folkeminnesamling, Universitetet i Oslo. Etterord av Marko Jouste, Markus Juutinen og Miika Lehtinen, Oulu universitet, Finland.

«Det er alltid skadelig med streik, det er ingen som tjener på det,» sa Stein Lier Hansen, leder i arbeidsgiverforeningen Norsk Industri, da det koronautsatte tariffoppgjøret endelig kom i gang. Likevel blir det streik, igjen og igjen. Hvordan kan det ha seg? Svaret er selvsagt at det lønner seg. Streik gir arbeidere lønnsøkninger og seire. Det sikrer arbeidstakerne makt bak kravene. Streik kan slik kalles hemmeligheten bak den norske arbeidslivsmodellen, og er avgjørende for å sikre et mer rettferdig samfunn.

Franz Kafka blev berømt i årene efter Anden Verdenskrig, i skyggen af atomtruslen og det 20. århundredes totalitarisme. Dengang lå det lige for at fortolke hans forfatterskab som et budskab fra en "kafkask" verden hvor det magtesløse menneske uvægerligt må bukke under for meningsløse bureaukratiske magter. Men Kafkas litterære værker er ikke "kafkaske". Tværtimod drømte han lige fra sine tidligste år om en politisk begivenhed, om et mirakuløst øjeblik hvor menneskene ikke er passive ofre for uforanderlige skæbnemagter, men selvstændige aktører der er i stand til at rokke ved fundamenterne for det fælles liv. I denne bog om en af modernismens vigtigste forfattere forsøger professor i litteraturvidenskab Isak Winkel Holm at trække Kafka ud af koldkrigstidens skygge og ind i vores tid.

Søren Kierkegaard skrev om det enkelte menneskes eksistens, og hans tekster er særdeles relevante også i dag. Den verdensberømte danske filosof beskriver og analyserer mange af de lidenskaber og muligheder, der fylder almindelige menneskers liv: kedsomhed, travlhed, humor, angst, fortvivlelse, tro, tvivl, ironi, kærlighed og forførelse, og Kierkegaard-kenderen Isak Winkel Holm har udvalgt en række vedkommende citater specielt til denne lille bog.

Sveriges sista bödlar, eller skarprättare som de hellre kallades, levde för inte så länge sedan – den allra sista dog 1920. Ändå representerade de ett gammaldags Sverige där frågor om rätt och fel värderades utifrån den mosaiska rättens skoningslösa principer.Det här är en krönika över en långlivad och sägenomspunnen yrkesgrupps upplösning i ett moderniserat land där den inte längre var önskvärd. Bödlarnas bakgrund och öden avslöjar en brokig grupp, och deras syn på yrket liksom omvärldens syn på dem varierade. Som denna bok kan visa ökade deras anseende ironiskt nog i takt med att straffen humaniserades, och även om somliga inte utövade sitt yrke mer än någon enstaka gång var deras plats i samhället långt ifrån självklar."Isak Lidströms De sista bödlarna ger en unik inblick i en föraktad yrkeskårs villkor och är i mångt och mycket en bortglömd historia." Bo Eriksson, Clio"Imponerad av både det flyt och den språkliga finess med vilken boken är skriven. De sista bödlarna är en otroligt intressant bok om bödlarnas tillvaro. 5/5"BTJ"Initierad skildring av de sista svenska bödlarna."Norrländska Socialdemokraten
