— In this paper, the problem of multi-vehicle cooperative interception of moving objects with unknown arrival times, trajectories and dynamics is investigated. The vehicles are assumed to have limited sensing and communication ranges. Therefore centralized approaches are not efficient, especially for the case of large number of vehicles and targets. In this(More)
Ultrasound elastography involves measuring the mechanical properties of tissue, and has many applications in diagnostics and intervention. A common step in different elastography methods is imaging the tissue while it undergoes deformation and estimating the displacement field from the images. A popular next step is to estimate tissue strain, which gives(More)
In this paper, the Maximum Reward Collection Problem (MRCP) in uncertain environments is investigated where multiple agents cooperate to maximize the total reward collected from a set of moving targets in the mission space with unknown arrival times, trajectories and dynamics. The reward with respect to each of the targets has a time discounting value and(More)
BACKGROUND Determination of β-D-Glucan (BDG) in the serum aids to diagnose the invasive fungal infections. The current study evaluated the diagnostic potential value of BDG assay in monitoring the disease in experimental systemic candidiasis in a rat model. The results can provide a useful preliminary data to improve this approach in developing countries.(More)
AIMS Minor head injury (MHI) is a common injury seen in Emergency Departments (ED). Computed tomography (CT) scan of the brain is a good method of investigation to diagnose intracranial lesions, but there is a disagreement about indications in MHI patients. We surveyed the post-traumatic symptoms, signs or past historical matters that can be used for the(More)
