We provide a general notion of a Digital Derivative in 1−dimensional grids, which has real or integer-only versions. From any such masks, a family of masks called skipping masks are defined. We prove general results of multigrid convergence for skipping masks. We propose a few examples of digital derivative masks, including the now well-known binomial mask. The corresponding skipping masks auto...

BACKGROUND The key to successful neonatal resuscitation is effective ventilation. Little evidence exists to guide clinicians in their choice of manual ventilation device or face mask. The expiratory tidal volume measured at the mask (V(TE(mask))) is a good estimate of the tidal volume delivered during simulated neonatal resuscitation. AIM To compare the efficacy of (a) the Laerdal infant resu...

Pressure vessel is a container used to store fluids under pressure and temperature. The fluids can be air, water, chemicals, fuel, gases etc. are most commonly used in food and chemical industries, oil refineries and so on. Pressure vessel is subjected to thermal and structural loads for power plant applications. Since the pressure vessel are subjected to both structural and thermal loads stres...

Vessel management calls for real-time traffic flow prediction, which is difficult under complex circumstances (incidents, weather, etc.). In this paper, a multimodal learning method named Prophet-and-GRU (P&G) considering weather conditions proposed. This model can learn both features of the long-term and interdependence multiple inputs. There are three parts our model: first, Decomposing L...

We present an overview of the design and test of an image processing procedure for detecting all important anatomical structures in color fundus images. These structures are the optic disk, the macula and the retinal network. The algorithm proceeds through five main steps: (1) automatic mask generation using pixels value statistics and color threshold, (2) visual image quality assessment using ...

Fundus retinal imaging is widely used in the diagnosis and management of eye disease. Blur commonly occurs in the acquisition and when it is severe the resulting loss of resolution hampers accurate clinical assessment. In this paper, we present a new technique to address this challenging problem. We make use of implicitly constrained image deblurring, which is known to provide improved results ...

in this paper, we describe a case of an aneurysmal circumflex artery connected to the coronary sinus through a fistula in a 40-year-old man with a two-year history of palpitation and chest pain. we discussed surgical management for patients with coronary artery fistula (caf), particularly for asymptomatic patients with a small left-to-right shunt .
