Using erlang in research and education in a technical university

Petrov I., Alexeyenko A., Ivanova G.

Computer Science

2018

Vol. 19 (3)

333--343

This paper addresses the problem of using functional programming (FP) languages for research and educational purposes. In order to identify the problems associated with the use of FP languages such as Erlang, an experiment consisting of two surveys was performed. The first survey was anonymous and aimed at establishing whether the participants prefer object-oriented or functional coding. The second one was a survey made after the students finished an Erlang course. The results of these two surveys demonstrate that functional programming is underrated with no apparent reasons. Possible steps to address this problem are suggested.

Implementing graph representation model for parallel and distributed systems using Erlang

Petrov I.

Computer Science

2016

Vol. 17 (1)

99--120

This paper describes a new model of graph representation using the Erlang actor model. Benefits of using lightweight processes instead of traditional passive data structures are given. Examples of using this model are shown. The experimental part gives two examples of using early implementations of the offered model. As a conclusion, an analysis of applicability for tasks from different branches of science is given.

Phase composition and catalytic properties of Ni-V oxide catalysts for dehydrotreatment of C9-aromatics.

The DTA, TG, DTG, XRD and IR techniques were employed to characterize the structure and phase composition of binary Ni-V oxide catalysts (0-100 mol.% NiO) prepared by coprecipitation from aqueous solutions of NH4VO3 and Ni(NO3)2 6H2O, followed by treatment of the precipitates obtained. The phase composition of nickel-vanadium samples calcined at 500C comprises both bulk phases of V2O5 and NiO (at NiO contents <= 75 and >= 75 mol.%, respectively) and nickel meta- and pyrovanades (~30-75 mol.% NiO). Besides that, at T > 500C, nickel orthovanadate is also appeared in nickelia-enriched samples (NiO >= 75 mol.%), its crystal structure being formed finally at T >= 700C. Catalytic activity of the NiO-V2O5 catalysts for ethylbenzene dehydrogenation has been found to be due to exclusively V2O5 phase (NiO<= 20 mol.%); other phases present in the NiO-V2O5 samples catalyze ethylbenzene cracking and dealkylation reactions mainly.
