Producing social mobility. Class and Travel in the Romanian Novel 1901-1932

2020

The present article addresses the Romanian novelistic production between 1901 and 1932 in the attempt of identifying a series of patterns regarding the protagonists’ social mobility. Starting with the most mentioned destinations throughout the novels, I analyse how and why the different social classes travel and try to determine the landmarks between which they dispute their physical presence, on the one hand, and their aspirations, on the other. On this basis, the second part of the article conducts a quantitative analysis of the major means of transport in the period – the train, the tramway, the coach/carriage, the automobile, the aeroplane, the ship, and the waggon – and attempts to pin…

Complex powers and non-compact manifolds

2002

We study the complex powers $A^{z}$ of an elliptic, strictly positive pseudodifferential operator $A$ using an axiomatic method that combines the approaches of Guillemin and Seeley. In particular, we introduce a class of algebras, ``extended Weyl algebras,'' whose definition was inspired by Guillemin's paper on the subject. An extended Weyl algebra can be thought of as an algebra of ``abstract pseudodifferential operators.'' Many algebras of pseudodifferential operators are extended Weyl algebras. Several results typical for algebras of pseudodifferential operators (asymptotic completeness, construction of Sobolev spaces, boundedness between apropriate Sobolev spaces, >...) generalize to…

Noise-tolerant efficient inductive synthesis of regular expressions from good examples

1997

We present an almost linear time method of inductive synthesis restoring simple regular expressions from one representative (good) example. In particular, we consider synthesis of expressions of star-height one, where we allow one union operation under each iteration, and synthesis of expressions without union operations from examples that may contain mistakes. In both cases we provide sufficient conditions defining precisely the class of target expressions and the notion of good examples under which the synthesis algorithm works correctly, and present the proof of correctness. In the case of expressions with unions the proof is based on novel results in the combinatorics of words. A genera…

Solutions of nonlinear PDEs in the sense of averages

2012

Abstract We characterize p-harmonic functions including p = 1 and p = ∞ by using mean value properties extending classical results of Privaloff from the linear case p = 2 to all pʼs. We describe a class of random tug-of-war games whose value functions approach p-harmonic functions as the step goes to zero for the full range 1 p ∞ .

Complex Numbers and Polynomials

2016

As mentioned in Chap. 1, for a given set and an operator applied to its elements, if the result of the operation is still an element of the set regardless of the input of the operator, then the set is said closed with respect to that operator.

Funkcionālā programmēšana mājaslapu izstrādē

2017

Tīmekļa vietnes kļūs aizvien funkcionāli bagātākas, kas padara tīmekļa vietnes klienta puses programmēšanu sarežģītāku, kas nozīmē, ka aizvien svarīgāk ir to labi strukturēt, kur izmantot var funkcionālo programmēšanu. Bakalaura darbā tiks apskatītas iespējas pielietot funkcionālās programmēšanas paradigmu tīmekļa vietnes klienta pusē. Darba mērķis ir izpētīt tīmekļa vietnes klientu pusi un funkcionālās programmēšanas iespējas tajā, kā arī salīdzināt tās ar ikdienas risinājumu. Tika gūta izpratne par tīmekļa vietņu klientu puses uzbūvi, apskatīti funkcionālās programmēšanas risinājumi tīmekļa vietņu klientu pusē, kā arī izstrādāts un salīdzināts risinājums, izmantojot funkcionālās programmē…

Surfactant Association: Recent Theoretical and Experimental Developments

1991

A theoretical model describing the association of ionic surfactants into rod-shaped micelles is combined with an approximate formula for the viscosity increase induced by rod-shaped aggregates. It is shown that most of the thermodynamic parameters of the association model can be obtained from viscosity measurements. The approach is applied to micellar solutions of hexadecylpyridinium salts. The pronounced effect of counter-ion concentration on the growth of rod-shaped micelles can be attributed to a slightly higher degree of counter-ion association in the cylindrical part than in the end portions. An attempt is made to explain the finding that the degree of counter-ion association is virtua…

Computation Cluster Validation in the Big Data Era

2017

Data-driven class discovery, i.e., the inference of cluster structure in a dataset, is a fundamental task in Data Analysis, in particular for the Life Sciences. We provide a tutorial on the most common approaches used for that task, focusing on methodologies for the prediction of the number of clusters in a dataset. Although the methods that we present are general in terms of the data for which they can be used, we offer a case study relevant for Microarray Data Analysis.

ROS/Gazebo Based Simulation of Co-operative UAVs

2019

UAVs can be assigned different tasks such as e.g., rendez-vous and space coverage, which require processing and communication capabilities. This work extends the architecture ROS/Gazebo with the possibility of simulation of co-operative UAVs. We assume UAV with the underlying attitude controller based on the open-source Ardupilot software. The integration of the co-ordination algorithm in Gazebo is implemented with software modules extending Ardupilot with the capability of sending/receiving messages to/from drones, and executing the co-ordination protocol. As far as it concerns the simulation environment, we have extended the world in Gazebo to hold more than one drone and to open a specif…
