Czech to English: Doppler Effect
General field: Science
Detailed field: Physics
Source text - Czech

Dopplerůvjev popisuje změnu frekvence a vlnové délky přijímaného oproti vysílanému signálu, způsobenou nenulovou vzájemnou rychlostí vysílače a přijímače.Jev byl poprvé popsán Christianem Dopplerem v roce 1842 v monografii Über dasfarbige Licht der Doppelsterne und einige andere Gestirne des Himmels.



Jestliže pohyblivý zdroj vysílá signál s frekvencí f0, pak stojící pozorovatel jej přijímá s frekvencí f:



f=f0*v/(v-vsr



kde v je rychlost vln v dané látce a vs,r relativní radiální rychlost zdroje vůči pozorovateli (kladná rychlost znamená přibližování, záporná vzdalování). Pro stacionární zdroj a pohyblivý přijímač je situace obdobná.



f=f0*(1 v0/v) ,



kde v0 je rychlost přijímače a pro přibližující se přijímač je kladná, pro vzdalující se je pak záporná.



Jedním z nejběžnějších příkladů, jak lze Dopplerův jev pozorovat, je změna výšky tónů vydávaných sirénou na vozidle projíždějícím okolo pozorovatele. Dopplerova jevu využívá řada měřicích přístrojů a zařízení, např. radary pro měření rychlosti vozidel nebo lékařské sonografy.



V astronomii se Dopplerův jev projevuje posuvem spektrálních čar vyzařovaných vesmírnými tělesy; pokud se tato tělesa vzdalují od Země, lze pozorovat takzvaný rudý posuv. Při vyšších rychlostech se však projevuje i dilatace času, je proto třeba brát v úvahu relativistický Dopplerův jev.



Translation - English

TheDoppler effect describes how the frequency and wave length differ in the transmitted and received signal due to a non-zero relative velocity between the transmitter and the receiver.The phenomenon was first described by Christian Doppler in 1842 in his treatise Überdas farbige Licht der Doppelsterne und einige andere Gestirne des Himmels.



If a moving source emits a signal with frequency f0, then a stationary observer will receive the same signal with frequency f given by:



f=f0*v/(v-vsr



where v is the the velocity of waves in the medium, and vs,r is the radial velocity of the source relative to the observer (positive if the relative distance decreases, negative it if goes up). The situation is similar for a stationary emitter and a moving receiver.



f=f0*(1 v0/v) ,



where v0 is the velocity of the receiver, which is positive for an approaching receiver and negative for a receding one.



One of the most common examples of the Doppler effect is the change in pitch in tones produced by a siren attached to a vehicle passing an observer. The Doppler effect is utilized by a number of measurement devices and apparatuses, e.g., Doppler radars for measuring the speed of moving objects, or medical sonographers.



In Astronomy, the Doppler effect is demonstrated by the shift of spectral lines emitted by celestial bodies. If such bodies are moving away from the Earth, a phenomenon known as red shift can be observed. For larger velocities, however, time dilation also comes into play, and the relativistic Doppler effect must be taken into account.



Czech to English: Transformers

Source text - Czech
Transformátor je elektrický netočivý stroj, který umožňuje přenášet elektrickou energii z jednoho obvodu do jiného pomocí vzájemné elektromagnetické indukce. Používá se většinou pro přeměnu střídavého napětí (např. z nízkého napětí na vysoké) nebo pro galvanické oddělení obvodů.


Ztráty nakrátko („v mědi“)
Jsou způsobeny ohmickým odporem vodiče tvořícího vinutí primární a sekundární cívky. Vinutí je obvykle z mědi nebo hliníku. Díky průchodu proudu tímto vodičem dochází k přeměně části přenášené energie na (Jouleovo teplo), které se vyzáří v podobě tepelné energie a způsobuje oteplení vinutí transformátoru. Ztráty nakrátko jsou proměnlivé podle úrovně zatížení transformátoru, tedy podle toho zda transformátorem teče nebo neteče proud.
Translation - English
The transformer is an electrical, non-rotating device that allows the transfer of electrical energy from one circuit to another by means of mutual electromagnetic induction. The device is usually used to transform alternating voltages, (e.g., to step up a low voltage to a higher one) or for galvanic isolation of circuits


Load Losses (Copper Losses, Winding Losses)
Load losses are the result of Ohmic resistance of the conductor of which the primary and secondary windings are made. The winding is usually made of copper or aluminum. As a result of the current passing through this conductor, part of the energy transferred is transformed into Joule heat, which is emitted as thermal energy and causes heating in the transformer’s winding. Winding losses vary according to changes in the transformer’s load, depending on whether or not current passes through the transformer.

Bio

General Information


I am a Czech guy bilingual in American English and Czech.
As of late, I have been using English primarily and in all aspects of my life. I am constantly working on improving myself and gaining knowledge about various fields of human endeavor. I have a background in Physics, but I also have a basic familiarity with various humanistic subjects, such as law, marketing, or management. For the last two years, I have been working hard on making inroads into computer programming (more on my LinkedIn profile).

My Translation Clients


My translation clients have appreciated me for my ability to grasp their text accurately and for ensuring logical correctness and accuracy in both the source and the target document. Being a native speaker of Czech, I understand the ins and outs of the language quite well, and thanks to my long-time immersion in English, I am well capable of producing English output that can satisfy many highly demanding American editors.

Additionally, I am a very meticulous person who takes great pains in making sure that my work is accurate, standard-compliant, consistent, and well readable to its target audience.

My Interpreting Clients


I am a state-certified interpreter for English in the Czech Republic. As far as my interpreting is concerned, my clients usually appreciate my easy-to-understand American English, my ability to easily understand various accents of English when translating into Czech, and my ability to handle even many technical topics with ease and professionalism.

I look forward to hearing from you!
