Kalman filter tracking and vertexing in a silicon detector for neutrino physics

2002

Abstract This article describes the application of Kalman filter techniques for the tracking and vertexing of particles inside the NOMAD-STAR detector, a silicon vertex detector installed in NOMAD, one of the neutrino oscillation experiments at the CERN-SPS. The use of the Kalman filter simplifies computationally the tracking and vertex procedure for NOMAD-STAR. The alignment of NOMAD-STAR is shown as an example of the application of the Kalman filter for tracking purposes. The accuracy of the method is such that one obtains alignment residuals between 9 and 12 μm . Furthermore, a preliminary measure of the impact parameter (with an RMS ∼36 μm ) illustrates the vertexing capabilities of thi…

“RecPack” a reconstruction toolkit

2004

We present a C++ toolkit to do tracking and vertex reconstruction. The toolkit incorporates common fitting methods, as the Kalman Filter, a framework to define a detector setup, a general navigation and a simple simulation. Furthermore, the toolkit provides a collection of interfaces which facilitates the addition of new fitting methods, trajectory models, geometrical objects, pattern recognition logic, etc. Although the toolkit was originally developed to be used in High Energy Physics, it could be applied to other fields.

Application of algae in active biomonitoring of the selected holding reservoirs in swietokrzyskie province

2016

Abstract During the years 2014-2015, biomonitoring studies were carried out at three holding reservoirs located in Swietokrzyskie Province (central Poland): Kielce artificial lake, Chancza reservoir and Sielpia reservoir. In sea water algae Palmaria palmata (Linnaeus) Weber & Mohr, exposed in the analysed waters, the increases of concentrations were determined by the atomic absorption spectrometry method (AAS), of the following: Mn, Fe, Cu, Zn, Cd and Pb. Conductivity and pH were also determined in the reservoirs waters. The differences between the increases of heavy metal concentrations in the samples of algae found along the coastline were indicated; they result from different distanc…

Invariant pattern recognition based on 1-D Wavelet functions and the polynomial decomposition

1997

Abstract A new filter, consisting of 1-D Wavelet functions is suggested for achieving optical invariant pattern recognition. The formed filter is actually a real function, hence, it is theoretically possible to be implemented under both spatially coherent and spatially incoherent illuminations. The filter is based on the polynomial expansion, and is constructed out of a scaled bank of filters multiplied by 1-D Wavelet weight functions. The obtained output is shown to be invariant to 2-D scaling even when different scaling factors are applied on the different axes. The computer simulations and the experimental results demonstrate the potential hidden in this technique.

Personāži ar hibrīdu identitātēm Amitava Goša un Salmana Rušdi romānos

2017

Šis maģistra darbs analizē personāžu hibrīdu identitātes un to savdabīgās balsis Salmana Rušdi un Amitava Goša romānos. Darba teorētiskā daļa ir balstīta uz krievu filozofa Mihaila Bahtina teorijām par heteroglosiju un polifoniju romānos, kā arī Edvarda Saida, Homi Babas, Roberta Janga un citu filozofu teorijām par koloniālismu, migrāciju, diasporām un hibriditāti. Darba praktiskā daļa izmeklē personāžu hibrīdu identitātes Salmana Rušdi un Amitava Goša romānos – “Magoņu jūra”, “Pusnakts bērni”, “Zeme zem viņas kājām” un “Maura pēdējā nopūta”. Pētījums pierāda, ka Amitavs Gošs un Salmans Rušdi meistarīgi iekļauj hibriditāti savos romānos, katram personāžam piešķirot specifisku un unikālu ide…

Propeller Flaps: A Review of Indications, Technique, and Results

2014

In the last years, propeller flaps have become an appealing option for coverage of a large range of defects. Besides having a more reliable vascular pedicle than traditional flap, propeller flaps allow for great freedom in design and for wide mobilization that extend the possibility of reconstructing difficult wounds with local tissues and minimal donor-site morbidity. They also allow one-stage reconstruction of defects that usually require multiple procedures. Harvesting of a propeller flap requires accurate patient selection, preoperative planning, and dissection technique. Complication rate can be kept low, provided that potential problems are prevented, promptly recognized, and adequate…

A one-pot cascade to protoberberine alkaloids via Stevens rearrangement of nitrile-stabilized ammonium ylides.

2015

A facile one-pot synthesis of protoberberines from readily accessible 1,2,3,4-tetrahydroisoquinoline-1-carbonitriles and 1,2-bis(bromomethyl)arenes is described. The reaction cascade comprises four consecutive transformations, all of which can be effected under a single set of conditions. Ten protoberberines, including the alkaloids pseudopalmatine and pseudoepiberberine, were prepared in yields up to 86% according to this strategy. No chromatographic purification of the products is required, and the route is devoid of any protecting group manipulations.
