Long Range Correlations in Chemical Oscillations

Abstract

Abstract:The purpose of the present study is to determine whether a long range correlation is present in BZ (Belousov-Zhabotinskii) reaction and how this correlation varies with the change in concentration of the solution. To explore the dynamics of the system with change in concentration, phase space plot and power spectrum are studied. Hurst exponent is estimated using lo g log plot and R/S technique. We discuss the results which uncover how the system changes from an excitable steady state to a limit cycle.

Navigating the Transition to a Decentralized Governance Model for State Universities in Uzbekistan

“…Stakeholders most affected by the reforms will experience a higher level of stress, which may cause feelings of insecurity and enhance the effect of rejection and subsequent resistance to change. Some stakeholders will actively resist the changes, seeing in the new corporate governance model their fears, disbelief, and inability to cope with the tasks set and achieve the strategic goals(Kotter & Schlesinger, 2008).Additionally, a lack of understanding of the role and tasks of the corporate body can reduce the effectiveness of the work of university supervisory boards(Chowdhury & Lang, 2016). This can slow down struggle between different stakeholders, resulting in conflicts and a lack of coordination in the management model(Hillman & Dalziel, 2003).…”
