Telepresence robots empower human operators to navigate remote environments. However, operating and navigating the robot in an unknown environment is challenging due delay communication network (e.g., distance, bandwidth, drop-outs etc.), processing delays slow dynamics of mobile resulting time-lagged system. Also, erroneous sensor data measurement which important estimate robot’s true state (p...

time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. the stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. it is well-known that the stabi...

conclusion we believed that the nonspecific clinical and laboratory finding of the present case and also the rarity of disease in our area especially in immunocompetent patients made his diagnosis confounding. patient we report an immunocompetent 43 years old iranian man who was in excellent health status until 3 weeksbefore hospitalization when he developed headache. he experienced a 5-week de...
