This paper deals with the optimal control problem for systems with state linear equality constraints. For deterministic linear systems, first we find various existence conditions for constraining state feedback control and determine all constraining feedback gains, from which the optimal feedback gain is derived by using the result of singular optimal control. For systems with stochastic proces...

The Mansouri-Sexl theory is a well known test theory of relativity. In the current paper we will derive the Mansouri-Sexl formalism for the light aberration and we will show how to improve on the theoretical and experimental basis by constraining the Mansouri-Sexl parameter “ ”. In the process of constraining the Mansouri parameter we devise a novel experiment for measuring and constraining li...

Small-scale fisheries (SSF) provide crucial contributions to livelihoods, food and nutrition security, the well-being of coastal communities worldwide. In Indonesia, 2.5 million households are involved in SSF production, yet these characterised by high poverty rates vulnerability due declining ecosystem health climatic change. this study we applied Sustainable Livelihoods Framework analyse char...
