Remains of mining in the territory of villages′ ervenica and Zlatá Baňa in the mountain range of Slanské vrchy
Rudolf Magula,Ján Brehuv
Acta Montanistica Slovaca , 2007,
Abstract: This article is devoted to the territory that is recondite for mining activities. It is situated in a north part of the mountain range of Slanské vrchy. There are villages that were known as mining villages in the past. The mining activities for gold, silver and mercury had only a local economical importance, beside of the output or production of opal. The output of opal on this territory was world noted, in the past. The aim of this article is to remit at some historical facts about former mines and to draw our attention to some attempts for building up, the educational and touristic path on this territory.
Forgotten constructions erected for mining and salt-works activities in Zlatá Baňa
Ján Brehuv,Rudolf Magula
Acta Montanistica Slovaca , 2008,
Abstract: Village Zlatá Baňa is known for the mining activities for gold, silver, mercury and antimony in the past. This article is devoted notto mining activities but to forgotten 2 dams, which were erected on the Delňa brook. The first was constructed above Zlatá Baňa fromwood in 1691 and does not exist presently. The second one was erected beneath Zlatá Baňa between 1802 – 1807 from stone and cementmortar. It exists up to this day but it is not working. The mentioned dams enabled to create water reservoirs. The first one enabled the water transport of wood trunksfrom latá Baňa to So ná Baňa in 1691 for a mining output of a salt-stone (or stone-salt). In the years 1807-1917, water from the second reservoir enabled the water transport of wood by a wooden flume 18,9 km long from Zlatá Baňa to the salt-works in Solivar. The mentioned dams and their water reservoirs enabled the high economical effectivity of the mining output of salt and salt-production of the salt-works in Solivar.

Iodine—A Potential Antioxidant and the Role of Iodine/Iodide in Health and Disease  [PDF]
Rudolf Winkler
Natural Science (NS) , 2015, DOI: 10.4236/ns.2015.712055
Abstract: In human physiology, iodine is primarily noted for its role in thyroid function and less so for its many extrathyroidal functions, particularly those based on its antioxidant properties. As I- it protects against free radicals and peroxides. This is seen in vitro in decreased depolymerization of hyaluronic acid and increased antioxidant status in human serum, and in vivo in increased antioxidant enzyme activities and decreases of malondialdehyde and peroxides. It could be shown or deduced that balneotherapeutic applications of iodine/iodide have a positive effect on cardiocirculatory diseases, respiratory disorders, some eye diseases (dry eye, cataract, age-related macular degeneration), and other degenerative diseases connected with increased oxidative stress that are also treated by balneotherapy.


Prevention of Iatrogenic Cervical Cancer  [PDF]
Rudolf Klimek
Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.514109
Abstract: Cervical carcinogenesis consists of natural occurring spontaneous cellular processes which may lead to self-organized dissipative structures of cervical cancers what was first explained in 1977 after several years of my biochemical, biophysical, hormonal and clinical studies. That was possible thanks to monograph “Biochemie der Tumoren” written in 1942 by Nobel Prize winner H. von Euler with my master Prof. B. Skarzynski. Today I express my gratitude to Nobelist Harald zur Hausen and his team for they discovered the nuclide sequences of HPV in genomes of cervical cancer cells which opened the possibility to describe the causal role of information in formula of reality. Vaccines built from the protein capsid of HPV have proved only the pathogenic information about the virus because of its lack of DNAs. All the theories of carcinogenesis have properly described this event from methodologically different point of view. The point is that one should understand the thermodynamic rules underlying each of these approaches. Neoplasms are self-organized from the cells of the patient, who did not provide the necessary conditions for cellular metabolism as defined in the moment of appearance of its zygote. In light of medical thermodynamics all oncogenic factors can divide into sufficient or necessary to events for creating a dissipathogenic cellular status. Cervical cancer is a tumor associated with the human papillomavirus as only its pathogenic dissipathogenic factors, but the genome of cervical carcinoma cells maybe the original source of many types of HPV from the peeled off cancer cells of the uterine cervix. Many things are known to increase the risk of carcinogenesis which as a natural process is an alternative of cellular or social death. Neoplasm cell is an effect of carcinogenesis, but not a causal point at which it begins its existence.
Towards Real-World Applications of Online Learning Spiral Recurrent Neural Networks  [PDF]
Rudolf SOLLACHER, Huaien GAO
Journal of Intelligent Learning Systems and Applications (JILSA) , 2009, DOI: 10.4236/jilsa.2009.11001
Abstract: Distributed intelligent systems like self-organizing wireless sensor and actuator networks are supposed to work mostly autonomous even under changing environmental conditions. This requires robust and efficient self-learning capabilities implementable on embedded systems with limited memory and computational power. We present a new solution called Spiral Recurrent Neural Networks (SpiralRNN) with an online learning based on an extended Kalman filter and gradients as in Real Time Recurrent Learning. We illustrate its stability and performance using artificial and real-life time series and compare its prediction performance to other approaches. SpiralRNNs perform very stable and show an ac-curacy which is superior or similar to other state-of-the-art approaches. In a memory capacity evaluation the number of simultaneously memorized and accurately retrievable trajectories of fixed length was counted. This capacity turned out to be a linear function of the size of the recurrent hidden layer, with a memory-to-size ratio of 0.64 for shorter trajectories and 0.31 for longer trajectories. Finally, we describe two potential applications in building automation and logistics and report on an implementation of online learning SpiralRNN on a wireless sensor platform under the TinyOS embedded operating system.
On Radiation by a Heavy Quark in SYM
Rudolf Baier
Advances in High Energy Physics , 2012, DOI: 10.1155/2012/592854
Abstract: A short note on radiation by a moving classical particle in supersymmetric Yang-Mills theory is discussed in this paper. 1. Introduction In papers [1–3], radiation by a point-like quark in supersymmetric Yang-Mills theory at strong coupling is investigated using the AdS/CFT correspondence in the supergravity approximation [4–6]. In this paper, modifications of the published radiation pattern are suggested, which are consistent with the results in [7]. This analysis is motivated by the description of electrodynamic radiation in classical electrodynamics [8, 9]. The important result in the context of radiation by an accelerated charge is given by the Abraham-Lorentz four-vector force [8, 10, 11] in classical relativistic electrodynamics [12] as where the particle velocity is and the acceleration with the proper time for the particle [13] (the signature used here is ). It is important to note the orthogonality of the force to the velocity as This force vanishes for uniformly accelerated motion, [8]. 2. Classical Radiation of Accelerated Electrons In order to set the framework, it is helpful to discuss radiation in classical electrodynamics. A usefull approach is found in the 1949 paper by Schwinger [9]. Assume sources, restricted to a finite domain, which emit radiation. The four-momentum of the classical electromagnetic field is given in terms of the energy-momentum tensor by integrating on a hyper-surface as follows: Gau? and Maxwell allow us to rewrite it as in terms of the current and the field-strength . In the following it is important in order to determine the radiation force that the radiation field tensor and the vector potential are introduced in terms of the retarded and advanced fields [10, 11] as follows: Replacing by in (2.2) gives , which for point-like charges satisfies (compare to (1.2)) Using current conservation and introducing the vector potential one obtains the power In [9, equation ( )], Schwinger discards the second term of this formula, which has the form of a total time derivative. The radiation vector potential [9] is expressed by A point-particle current is assumed as The integrals in (2.6) are as follows: with , , and from equation of [9] one obtains with and . Finally, using the notion of emitted power and a Schott-type term (e.g., in the notation of [14]), the result of the angular radiation pattern is where Indeed, there are two terms contributing to the radiation power. Schwinger [9] claims that only the first one , the one denoting the emission, should be retained. It has the characteristics of an irreversible energy
Infinite-Dimensional Lie Groups and Algebras in Mathematical Physics
Rudolf Schmid
Advances in Mathematical Physics , 2010, DOI: 10.1155/2010/280362
Abstract: We give a review of infinite-dimensional Lie groups and algebras and show some applications and examples in mathematical physics. This includes diffeomorphism groups and their natural subgroups like volume-preserving and symplectic transformations, as well as gauge groups and loop groups. Applications include fluid dynamics, Maxwell's equations, and plasma physics. We discuss applications in quantum field theory and relativity (gravity) including BRST and supersymmetries. 1. Introduction Lie groups play an important role in physical systems both as phase spaces and as symmetry groups. Infinite-dimensional Lie groups occur in the study of dynamical systems with an infinite number of degrees of freedom such as PDEs and in field theories. For such infinite-dimensional dynamical systems, diffeomorphism groups and various extensions and variations thereof, such as gauge groups, loop groups, and groups of Fourier integral operators, occur as symmetry groups and phase spaces. Symmetries are fundamental for Hamiltonian systems. They provide conservation laws (Noether currents) and reduce the number of degrees of freedom, that is, the dimension of the phase space. The topics selected for review aim to illustrate some of the ways infinite-dimensional geometry and global analysis can be used in mathematical problems of physical interest. The topics selected are the following.(1)Infinite-Dimensional Lie Groups.(2)Lie Groups as Symmetry Groups of Hamiltonian Systems.(3)Applications.(4)Gauge Theories, the Standard Model, and Gravity.(5)SUSY (supersymmetry). 2. Infinite-Dimensional Lie Groups 2.1. Basic Definitions A general theory of infinite-dimensional Lie groups is hardly developed. Even Bourbaki [1] only develops a theory of infinite-dimensional manifolds, but all of the important theorems about Lie groups are stated for finite-dimensional ones. An infinite-dimensional Lie group is a group and an infinite-dimensional manifold with smooth group operations Such a Lie group is locally diffeomorphic to an infinite-dimensional vector space. This can be a Banach space whose topology is given by a norm , a Hilbert space whose topology is given by an inner product , or a Frechet space whose topology is given by a metric but not by a norm. Depending on the choice of the topology on , we talk about Banach, Hilbert, or Frechet Lie groups, respectively. The Lie algebra?? of a Lie group is defined as left invariant vector fields on (tangent space at the identity ). The isomorphism is given (as in finite dimensions) by and the Lie bracket on is induced by the Lie bracket of
Classification Metrics for Improved Atmospheric Correction of Multispectral VNIR Imagery
Rudolf Richter
Sensors , 2008, DOI: 10.3390/s8116999
Abstract: Multispectral visible/near-infrared (VNIR) earth observation satellites, e.g., Ikonos, Quickbird, ALOS AVNIR-2, and DMC, usually acquire imagery in a few (3 – 5) spectral bands. Atmospheric correction is a challenging task for these images because the standard methods require at least one shortwave infrared band (around 1.6 or 2.2 μm) or hyperspectral instruments to derive the aerosol optical thickness. New classification metrics for defining cloud, cloud over water, haze, water, and saturation are presented to achieve improvements for an automatic processing system. The background is an ESA contract for the development of a prototype atmospheric processor for the optical payload AVNIR-2 on the ALOS platform.
