In this paper, we look into the dynamic motion planning and control of an unmanned aerial vehicle, namely, the quadrotor, governed by its dynamical equations.It is shown for the first time that the Direct or the Second Method BEARD BALM of Lyapunov is an effective tool to derive a set of continuous nonlinear control laws that not only provide smoot
Abstract Low-intensity focused ultrasound (LIFU) neuromodulation requires precise targeting and high resolution enabled by phased array transducers and beamforming.However, focusing optimization usually relies on phantom measurements or simulations with inaccurate acoustic properties to degrade neuromodulation resolution.Therefore, this work analyz
We review the current status of metallic photocathodes based on thin films prepared by pulsed laser deposition (PLD) and we explore ways to improve the performance of these devices.PLD seems to be a very efficient and suitable technique for producing adherent and uniform thin films.Time-resolved mass spectrometric investigations definitively Moistu
Abstract Background A controlled, blind research study was conducted to define the initial inflammatory response and lung damage associated with the death of immature adult Dirofilaria immitis in cats as compared with cats developing adult heartworm infections and cats on preventive medication.Methods Three groups of cats were utilized, 10 per grou
