Ritz Solution for Transient Analysis of Variable-Stiffness Shell Structures
2020
The dynamic response of thin-walled structures is driven by mass and stiffness distribution. As such, variable-stiffness (VS) composites offer opportunities to tune structural dynamic responses. To this extent, efficient analysis tools become increasingly important for structural analysis and design purposes. In this work, an efficient and versatile Ritz method for free vibrations and linear transient analysis of VS doubly curved shell structures is presented. VS shell structures are modeled as an assembly of shell-like domains. The shell kinematics is based on the first-order shear deformation theory, and no further assumption is made on the shallowness or on the thinness of the structure.…
Piemēru veidi mūsdienu angļu valodas mācību vārdnīcās
2019
Pastāv daudz veidi kā cilvēki, kuri mācās svešvalodu var apgūt jaunu vārdu krājumu. Viens no tiem ir skatīt piemērus kā vārdi tiek izmantoti kontekstā, starp cilvēkiem, kuriem konkrētā valoda ir dzimtā. Angļu valodas monolingvālās mācību vārdnīcas iekļauj daudz šādus piemērus, padarot tās par vienu no labākajiem avotiem. Šī bakalaura darba mērķis ir pētīt piemēru veidus, to skaitu, šķirkļa vārdu biežuma un polisēmijas ietekmi uz piemēru skaitu, un piemēru veidus daudznozīmīgu vārdu šķirkļos trīs mūsdienu angļu valodas mācību vārdnīcās - Oxford Advanced Learner’s Dictionary, Macmillan English Dictionary for Advanced Learners un Longman Dictionary of Contemporary English. Pētījums iekļauj māc…
Pb-PbOHCl Composite Nanowires Synthesized by Galvanic Deposition in Template
2019
In this paper, we report a detailed study on the synthesis of composite nanowires of Pb-PbOHCl via galvanic deposition into the pores of a membrane acting as a template. PbOHCl deposition quantitatively occurs as the solution pH exceeds the value of about 4.12. Simultaneously, owing to the galvanic coupling, electro-deposition of lead occurs, so composite nanowires were formed. The role of different parameters controlling the kinetic evolution of the process, such as oxygen bubbling, solution pH, surface area and type of sacrificial anode were investigated one at a time. The results suggest that every modification accelerating the alkalization of the solution inside the template pores favor…
Natural Addition of Ordinals
2019
Summary In [3] the existence of the Cantor normal form of ordinals was proven in the Mizar system [6]. In this article its uniqueness is proven and then used to formalize the natural sum of ordinals.

Extracting multi-mode ERP features using fifth-order nonnegative tensor decomposition
2018
Background Preprocessed Event-related potential (ERP) data are usually organized in multi-way tensor, in which tensor decomposition serves as a powerful tool for data processing. Due to the limitation of computation burden for multi-way data and the low algorithm performance of stability and efficiency, multi-way ERP data are conventionally reorganized into low-order tensor or matrix before further analysis. However, the reorganization may hamper mode specification and spoil the interaction information among different modes. New method In this study, we applied a fifth-order tensor decomposition to a set of fifth-order ERP data collected by exerting proprioceptive stimulus on left and right…
Nome e numero: una parentela.
2014
In this paper we describe the relationships between two fundamental “cognitive gestures” of human beings: naming and counting. In particular, we try to define these relationships by examining the theoretical efforts of such authors as Euclide, Frege, Wittgenstein, Chomsky and Aristotle. The analysis is centered around justifying the mutual dependence between noun and number in human cognition.
Pedagoģiskie risinājumi 5-6 gadu bērnu ar īpašām redzes vajadzībām matemātiskās kompetences attīstīšanai
2016
Šī pētījuma mērķis ir izpētīt, kāds būtu vispiemērotākais pedagoģiskais risinājums (pieeja un procesi), lai bērni vecumā no 5-6 gadiem ar īpašām vizuālajām vajadzībām iegūtu matemātisko kompetenci. Pētījumā tiek aplūkoti skaitļa jēdziena teorētiskie pamati un analizēti skaitļu mācīšanās posmi un to nozīmīgums šajā vecumā. Matemātiskā domāšana attīstās, bērnam nodarbojoties ar matemātiku. Matemātiskajā jomā domāšanas stingrība ir būtiska pazīme jau no pirmās mācīšanās pieredzes. Empīriskajā daļā tika izpētīta skaitļa jēdziena izpratne un matemātiskās domāšanas apguves procesi, anketējot bijušos studentus, kuri atsauca atmiņā savu matemātikas apguves procesu un tā tālākizmantošanu izglītības …
Simplified stock markets and their quantum-like dynamics
2009
In this paper we continue our systematic analysis of the operatorial approach previously proposed in an economical context and we discuss a mixed toy model of a simplified stock market, i.e. a model in which the price of the shares is given as an input. We deduce the time evolution of the portfolio of the various traders of the market, as well as of other observable quantities. As in a previous paper, we solve the equations of motion by means of a fixed point like approximation.
