Localization of UAVs from Camera Image

Tématem této práce je využití neuronových sítí pro lokalizaci kvadrokoptér. Řešení práce spočívá v důkladném prostudování látky a návrhu algoritmu, který bude schopen správně detekovat a lokalizovat UAV z kamerového výstupu pomocí neuronových sítí. Práce se zabývá rozborem neuronových sítí, vhodným výběrem sítě pro řešení problematiky, jejím návrhem a vytvořením funkčního algoritmu schopného detekovat a označit objekty v reálném čase. Kromě přípravy algoritmu pro živý vstup je jeho funkcionalita ozkoušena na testovací sadě obrazů pro získání ucelené informace o přesnosti. Výsledky testů jsou následně rozebrány a z nich jsou vyvozeny možné návrhy na zlepšení.The goal of this work is to test the possibility of using neural networks to localize UAVs. Solution for this problem lies in an extensive research of given subject and in the development of algorithm, which will be able to detect and localize flying quadrocopters from video stream. This work will provide a thorough analysis of neural networks, proper network design and the development of functional algorithm, capable of live stream object marking. Apart from preparing the algorithm for live feed input, the functionality of this program will be tested on a set of pictures to properly analyze the precision. Results of these tests will be discussed in final suggestion for future upgrades

3-3-1 Models With Unique Lepton Generations and Analysis of Higgs Decays

We examined several 3-3-1 Models containing three unique lepton generations -- each generation has unique quantum numbers and uses the other generations to fully cancel anomalies. These models have been previously discussed in a paper published by Marc Sher and David Anderson [2]. Using new data from the LHC [5], we revisited the Higgs decays presented in these models, and analyzed their viability. Despite the theoretical possibility for extending the Standard Model, none of the models proposed by Anderson and Sher in 2005 have survived experimental verification. We will provide background information on the Standard Model, introduce some of the possible extensions of it, and then show how these extensions failed in comparison to experimental data

Design and Characterization of a Neutron Calibration Facility for the Study of sub-keV Nuclear Recoils

As part of an experimental effort to demonstrate sensitivity in a large-mass detector to the ultra-low energy recoils expected from coherent neutrino-nucleus elastic scattering, we have designed and built a highly monochromatic 24 keV neutron beam at the Kansas State University Triga Mark-II reactor. The beam characteristics were chosen so as to mimic the soft recoil energies expected from reactor antineutrinos in a variety of targets, allowing to understand the response of dedicated detector technologies in this yet unexplored sub-keV recoil range. A full characterization of the beam properties (intensity, monochromaticity, contaminations, beam profile) is presented, together with first tests of the calibration setup using proton recoils in organic scintillator.Comment: submitted to Nucl.

Charges, Monopoles and Duality Relations

A charge-monopole theory is derived from simple and self-evident postulates. Charges and monopoles take an analogous theoretical structure. It is proved that charges interact with free waves emitted from monopoles but not with the corresponding velocity fields. Analogous relations hold for monopole equations of motion. The system's equations of motion can be derived from a regular Lagrangian function.Comment: 17 pages + 3 figures

Q-balls in Underground Experiments

In this paper we present some features of Q-balls and we discuss their interactions with matter, and their energy losses in the Earth, for a large range of velocities. These calculations are used to compute the fractional geometrical acceptance of the MACRO detector. Furthermore a systematic analysis of the energy losses of Q-balls in three types of detectors is investigated. More specifically we have computed the light yield in liquid scintillators, the ionization in streamer tubes and the Restricted Energy Loss in the CR39 nuclear track detectors.Comment: 7 pages, 4 PS figures included with epsfig, uses espcrc2.sty Talk given at the Sixth Topical Seminar on Neutrino and Astroparticle Physics, San Miniato, Italy, 17-21 May 199

Computational Knowledge Integration in Biopharmaceutical Research

An initiative to increase biopharmaceutical research productivity by capturing, sharing and computationally integrating proprietary scientific discoveries with public knowledge is described. This initiative involves both organisational process change and multiple interoperating software systems. The software components rely on mutually supporting integration techniques. These include a richly structured ontology, statistical analysis of experimental data against stored conclusions, natural language processing of public literature, secure document repositories with lightweight metadata, web services integration, enterprise web portals and relational databases. This approach has already begun to increase scientific productivity in our enterprise by creating an organisational memory (OM) of internal research findings, accessible on the web. Through bringing together these components it has also been possible to construct a very large and expanding repository of biological pathway information linked to this repository of findings which is extremely useful in analysis of DNA microarray data. This repository, in turn, enables our research paradigm to be shifted towards more comprehensive systems-based understandings of drug action

The Energy Spectra and Relative Abundances of Electrons and Positrons in the Galactic Cosmic Radiation

Observations of cosmic-ray electrons and positrons have been made with a new balloon-borne detector, HEAT (the "High-Energy Antimatter Telescope"), first flown in 1994 May from Fort Sumner, NM. We describe the instrumental approach and the data analysis procedures, and we present results from this flight. The measurement has provided a new determination of the individual energy spectra of electrons and positrons from 5 GeV to about 50 GeV, and of the combined "all-electron" intensity (e+ + e-) up to about 100 GeV. The single power-law spectral indices for electrons and positrons are alpha = 3.09 +/- 0.08 and 3.3 +/- 0.2, respectively. We find that a contribution from primary sources to the positron intensity in this energy region, if it exists, must be quite small.Comment: latex2e file, 30 pages, 15 figures, aas2pp4.sty and epsf.tex needed.

The Search for Stable, Massive, Elementary Particles

In this paper we review the experimental and observational searches for stable, massive, elementary particles other than the electron and proton. The particles may be neutral, may have unit charge or may have fractional charge. They may interact through the strong, electromagnetic, weak or gravitational forces or through some unknown force. The purpose of this review is to provide a guide for future searches - what is known, what is not known, and what appear to be the most fruitful areas for new searches. A variety of experimental and observational methods such as accelerator experiments, cosmic ray studies, searches for exotic particles in bulk matter and searches using astrophysical observations is included in this review.Comment: 34 pages, 8 eps figure
