This paper investigates the time optimal control problem to a target set for semilinear control systems involving time delays or memories when a principal operator is unbounded by the construction of a fundamental solution and an easy consequence of the definition of real interpolation spaces. A convergence theorem of time optimal controls for the given semilinear retarded system to a point target set is also given.
A message broker is widely used to enable applications, systems, and services to communicate with each other. One of the widely used message brokers is RabbitMQ that provides various functions and stability. However, as presented in this paper, Rab-bitMQ is vulnerable. In this paper, we present how RabbitMQ is exploited by protocol fuzzing, which is a common way to find unknown vulnerabilities inherent in software. We describe our protocol fuzzing procedures in detail and present conducted results.
Abstract. This paper deals with the existence and uniqueness of solutions for the nonlinear functional differential equations with time delay. The regularity and a variation of constant formula for solutions of the given equations are also studied.Mathematics subject classification (2010): 35F25, 35K55.
