My professional life includes working as a writer, an editor, a fabricator and as well a mathematician. I received my Ph. D. in 2007 from the University of Calabar and have taught for several years in the same institution before transferring my service to Akwa Ibom State University. Other institutions I have taught include University of Uyo and Maritime Academy Oron. I am especially interested in Integral Equations, Oscillation Theory for Impulsive Differential Equations and related areas in analysis.<\/span><br><\/p>\n<p class=\"MsoNoSpacing\" style=\"text-align:justify\"><span style=\"font-size:12.0pt;\nfont-family:&quot;Times New Roman&quot;,serif;color:#00000A\"><strong><\/strong>Qualifications<o:p><\/o:p><\/span><\/p><p class=\"MsoNoSpacing\" style=\"margin-top:0cm;margin-right:0cm;margin-bottom:\n6.0pt;margin-left:35.7pt;text-align:justify;text-indent:-17.85pt;mso-list:l0 level1 lfo1\"><!--[if !supportLists]--><span style=\"font-size: 12pt; font-family: Symbol;\">\u00b7<span style=\"font-stretch: normal; font-size: 7pt; line-height: normal; font-family: &quot;Times New Roman&quot;;\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\n<\/span><\/span><!--[endif]--><span style=\"font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 10);\">Doctor of Philosophy (Ph.

This circle of problems plays an important role in real life since in any design, there are unexpected events. Stochastic differential equations discuss these problems among others in modelling statistical mechanics. It was Barnov and his associates who first formulated the deterministic model of the impact of impulse effects on systems.<o:p><\/o:p><\/span><\/p><p class=\"MsoNoSpacing\" style=\"text-align: justify;\"><span style=\"font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 10);\">Barnov\u2019s initiatives had a strong influence on the research direction in all the countries that embraced the concept. Consequently, some fundamental aspects of research areas which play important role in such applications as the treatment of delay equations and some other fields missed certain valuable points. There is need to develop a new formulation of the problem that contains the whole Barnovian theory and addresses the circle of problems missing in Barnov\u2019s approach. These changes among others include:<\/span><o:p><\/o:p><\/p><p class=\"MsoNoSpacing\" style=\"text-align: justify;\"><span style=\"font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 10);\">&nbsp;<\/span><\/p><p class=\"MsoNoSpacing\" style=\"margin-left: 36pt; text-align: justify; text-indent: -18pt;\"><span style=\"font-size: 12pt; font-family: Symbol; color: rgb(0, 0, 10);\">\u00b7<span style=\"font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 7pt; line-height: normal; font-family: &quot;Times New Roman&quot;;\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/span><\/span><span style=\"font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 10);\">The addition of impulse effects on the dynamics of the system like impacts of impulses on the engine;<o:p><\/o:p><\/span><\/p><p class=\"MsoNoSpacing\" style=\"margin-left: 36pt; text-align: justify; text-indent: -18pt;\"><span style=\"font-size: 12pt; font-family: Symbol; color: rgb(0, 0, 10);\">\u00b7<span style=\"font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 7pt; line-height: normal; font-family: &quot;Times New Roman&quot;;\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/span><\/span><span style=\"font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 10);\">Uniform treatment for delay and non-delay impulsive differential equations;<o:p><\/o:p><\/span><\/p><p class=\"MsoNoSpacing\" style=\"margin-left: 36pt; text-align: justify; text-indent: -18pt;\"><span style=\"font-size: 12pt; font-family: Symbol;\">\u00b7<span style=\"font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-size: 7pt; line-height: normal; font-family: &quot;Times New Roman&quot;;\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/span><\/span><span style=\"font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 10);\">Extension of Barnov\u2019s coordinate space model of impulses to phase state model where impulse may affect both the coordinates and the impulse momentum.<\/span><o:p><\/o:p><\/p><p class=\"MsoNoSpacing\" style=\"margin-left: 36pt; text-align: justify;\"><span style=\"font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 10);\">&nbsp;<\/span><\/p><p class=\"MsoNoSpacing\" style=\"text-align: justify;\"><span style=\"font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 10);\">It is worthy of note that the framework of functions of bounded variation gives a chance to build together the coordinate space impulses with the impulses on the system dynamics into a consistent system.
