Graphene is only one atom thick, optically transparent, chemically inert, and an excellent conductor. These properties seem to make this material an excellent candidate for applications in various photonic devices that require conducting but transparent thin films. In this letter, we demonstrate liquid crystal devices with electrodes made of graphene that show excellent performance with a high ...

Hypertension continues to be a major contributor to global morbidity and mortality, fuelled by an abundance of patients with uncontrolled blood pressure despite the multitude of pharmacological options available. This may occur as a consequence of true resistant hypertension, through an inability to tolerate current pharmacological therapies, or non-adherence to antihypertensive medication. In ...

In this paper we introduce a novel concept, which considers all the autonomous devices on the user 's Personal Area Network (PAN) as one big "Virtual Device" having multiple input and output units and providing a coherent and surround interface to the user. Such a concept is quite valuable to the user since it allows him to manage all his devices as one. The paper also proposes and describes a ...

The wireless devices that will soon be part of our day-today lives, and that may be the focus of our attention in our occupation today, will become more complex and more integrated into our lives. And there will be more to come. That the new devices will be more complex, both in the design phase and in the manufacturing test phase, is a certainty. History has shown this to be the case. As these...

Hypertension is a major public health issue and due to poor blood pressure (BP) control rates, worldwide, alternative nonpharmacological therapies are being sought to help improve blood pressure control. There are multiple catheter-based renal denervation (RDN) devices that are available and being studied in various hypertensive populations. The procedure has been shown to be safe, but the effi...

The AGV (automated guided vehicle) was introduced in UK in 1953 for transporting. But nowadays, due to their high efficiency, flexibility, reliability, safety and system scalability, they are used in various application in industries. In brief, the AGV robot is a system which typically made up of vehicle chassis, embedded controller, motors, drivers, navigation and collision avoidance sensors, ...
