Lifebuoy systems are efficient means of life saving equipment in the marine industry. Most marine-companies uses lifebuoy with mooring-line connections subjected to unpredictability of waves and non-linearities from mooring lines along with risk associated from fluctuating water waves. The suitability of the equipment due to heave motion can be assessed by the computation using Matlab software. There is a rapid fall in force on the bottom and top from a time frame of 5 to 10s and a maximum force of 5.8N and 7.6N was recorded respectively. A heave response of -0.15m to 0 was observed. During this analysis the lifebuoy will experience little heave response. A Matlab program was used in analysing this process

Sama-ae [18] characterized local boundedness and boundedness of the superposition operator acting from the Maddox sequence spacel(p) into l1. Sağır & Güngör [14]defined the superposition operator P_g where g:N²×R→R by P_g (x)=(g(k,s,xks) )_(k,s=1)^∞ for all real double sequences (xks ). The main goal of this paper is constructing the necessary and sufficient conditions for the local boundedness and boundedness of the superposition operatorP_gacting from Maddox double sequence spaces L(p) into L(q) where p=(pks ) and q=(qks ) is bounded double sequences of positive numbers.

There have been many researching about of non-Newtonian calculus and superposition operators until present. The non-Newtonian superposition operator was introduced by Sağır and Erdoğan in [15]. In this study, *-locally boundedness and *-boundedness of the non-Newtonian superposition operator NPf:L p,α -> L 1,β were characterized.
