Variation in the geoid height detected by the mission GRACE
Kostelecký, J.; Bezděk, Aleš; Klokočník, Jaroslav
2014 - Czech Time variability of the gravity field, provided by the GRACE mission since 2002, presented here is based on the transformation of monthly gravity field models to the geoid. We show the changes caused by the global water cycle and land hydrology. Časově proměnné gravitační pole, získané z pozorování mise GRACE od roku 2002, je v tomto příspěvku založené na transformaci měsíčních gravitačních polích na výšku geoidu. Ukážeme gravitační změny působené globálním hydrologickým cyklem a hydrologií na pevninách.

Cosmology, Numbers and the Platon’s Soul of the World
Rajchl, Jaroslav
2011 - Czech The present status of cosmology is characterized by a variety of many different models. Nevertheless, it shows that some type of duality of both dynamical and the structural nature is typical. Its common source is the Big Bang (BB). To reconcile this very rich manifold we use the Plato’s model „of the World Soul”. Its main idea is the Pythagoras’ one of the role of numbers as fundamental elements of all the things in the World. Současná kosmologie se vyznačuje velkým množstvím nejrůznějších modelů. Bližší pohled ukazuje, že všechny oplývají určitým typem dualnosti, a sice propojením dynamické a formativní podoby, jejichž společným zdrojem je známý Velký třesk (BB). Abychom zpřehlednili onen složitý obraz, vybrali jsme jako určitý sjednocující symbol tzv. Platonův model duše světa (PDS), který vychází z Pythagorova postřehu, že analogickou dualností se vyznačují i čísla.

Regularities in the magnetic field distribution on the Sun in time
Bumba, Václav; Klvaňa, Miroslav
2009 - Czech Solar background (weak) magnetic fields are very regularly distributed on the solar surface. These regularities change with the range of heliographic latitudes ant they are observable during more than four solar cycles. Sluneční pozaďová (slabá) magnetická pole jsou na povrchu Slunce rozdělena velmi pravidelně. Tyto pravidelnosti se mění s rozsahem heliografických šířek a jsou pozorovatelné v celém rozsahu více než čtyř slunečních cyklů.

Displacements of Doppler velocity fields in sunspots
Klvaňa, Miroslav; Bumba, Václav
2009 - Czech The mean value of Doppler velocity field in magnetized regions shows a sytematic redshift compared to the neighbouring non-magnetic regions in the range 37 – 191 m/s. Changes in the morphology of the Evershed effect are analyzed. Střední hodnota dopplerovského rychlostního pole v oblastech vyplněných magnetickým polem vykazuje systematický rudý posuv vůči sousedním oblastem bez magnetického pole v rozmezí 37 – 191 m/s.

Complementary cooperation, the Cardano's world, and the incompletness
Rajchl, Jaroslav
2008 - Czech The Cardano’s world (CW) is characterized by the well known phrase about the triadicity of all the good and bad! It contains a cubic nonlinearity (NL) as its mainbase, together with the linear, bilinear and quadratic components (i.e. the positive and negative solutions). All these components are fundamental for its dynamical cooperative and relative stability as a system. But, the relation between its quadratic and cubic (NL) is, as has been shown previously, of paradoxical nature (Rajchl 2006), which is the source of dynamical evolution of (CW). It is shown that such a system is incomplete in the sense, that it evolves behind its relative stability state (dimension 3) to the deterministic chaos. Cardanuv svet muže být charakterizován oním dobre známým rcením: „do tretice všeho dobrého i zlého“. Je nelineární (NL) s dimensí 3 a tím i relativne stabilní. Obsahuje v sobe navíc ješte linearitu i kvadratickou nelinearitu (tj. obsahuje ono dobré a zlé jako kladné a záporné), ale i soucinnost komplementárního jako bi-linearitu. Ve vztahu kvadratického a kubického (jak jsme ukázali již loni) je i paradoxní, což zakládá navíc i jeho dynamicnost. Je však, jak se ukazuje ( Keywords: complementary cooperation; Cardano's world Available at various institutes of the ASCR Complementary cooperation, the Cardano's world, and the incompletness

Virtual 3D Space
Klvaňa, Miroslav
2005 - Czech We investigate the possibility of a direct visual observation of two color stereoscopic images in order to perceive these images spatially without the use of further technical aids. Such a method of the 3D effect evoking is known since a long time ago, but there are not many information concerning it, and they are mostly very inaccurate. Práce se věnuje možnosti přímého vizuálního pozorování dvou barevných stereosko-pických obrazů, vedoucí k vyvolání prostorového vjemu, bez použití dalších technických pomůcek. Tento způsob vzniku trojdimenzionálního (3D) efektu je znám již z minulosti, informace o něm jsou však řídké a většinou povrchní.

Trains in our world
Rajchl, Jaroslav
2005 - Czech According to e.g. St. Thomas the human history is connected with the mankind behaviour which is well known is tighly connected with the solar activity during its 500 year periodicity. Owing to this activity trains of various shapes and duration are induced; they are in an interesting correspondence to different typical processes in the mankind history. Již Tomáš Akvinský si všiml, že historie lidstva je těsně spojata s chováním lidí. Toto chování je ve stati spojeno s vlivem sluneční činnosti a její 500letou periodičností. Ta se v různých historických etapách projevuje ve formě stop, různých tvrů a trvání odpovídajících různým dějinným procesům.
