Вильнюсский старообрядческий Покровский храм как памятник культурного наследия: архитектурные особенности и городской ландшафт

The purpose of this article is to analyze and interpret the architectural features of the Pomorian Pokrovsky church in Vilnius as a monument of cultural heritage. Pokrovsky church is one of the largest and most valuable part of this Old Believers complex and the cultural heritage of the Old Believers in Vilnius. Neoclassicism with its symmetry and restrained elegance dominates on the exterior of this church. In 1905-1906, after the construction of the church bell tower appeared bright features of the neo-Russian style. These two architectural styles harmoniously complement each other and give the Pokrovsky church a unique identity that distinguishes it from all other Old Believers churches in Lithuania, Latvia, Estonia and Poland.

Path-Following Bifurcation Analysis of Church Bell Dynamics

In this paper, we perform a path-following bifurcation analysis of church bell to gain an insight into the governing dynamics of the yoke–bell–clapper system. We use an experimentally validated hybrid dynamical model based on the detailed measurements of a real church bell. Numerical analysis is performed both by a direct numerical integration and a path-following methods using a new numerical toolbox ABESPOL (Chong, 2016, “Numerical Modeling and Stability Analysis of Non-Smooth Dynamical Systems Via ABESPOL,” Ph.D. thesis, University of Aberdeen, Aberdeen, UK) based on COCO (Dankowicz and Schilder, Recipes for Continuation (Computational Science and Engineering), Society for Industrial and Applied Mathematics, Philadelphia, PA). We constructed one-parameter diagrams that allow to characterize the most common dynamical states and to investigate the mechanisms of their dynamic stability. A novel method allowing to locate the regions in the parameters' space ensuring robustness of bells' effective performance is presented.

Official regulations and perceptual aspects of bell ringing

Through the analytical approach of studying official and perception-related discourse on bell ringing I accentuate the complexity of aspects that the sound of church bell presents in contemporary society. I point out the misleading officially defined level of noise nuisance and reveal how, when and why bell ringing is perceived as a positive or negative part of the acoustic environment. The study argues for a holistic approach to the noise nuisance issues, still much underestimated in the official discourse, that co-create our everyday soundscape.
