In this paper, the boundary-based estimation of pressure distribution in the cardiovascular system is investigated using two dimensional flow images. The conventional methods of non-invasive estimation of pressure distribution in the cardiovascular flow domain use the differential form of governing equations. This study evaluates the advantages of using the integral form of the equations in the...

carbon dioxide flooding is considered to be one of the most effective enhanced oil recovery methods for the light oil reservoirs. depending on the operating pressure, the process might be miscible or immiscible. minimum miscibility pressure (mmp) is the most important parameter for assessing the applicability of any miscible gas flood for an oil reservoir. the miscibility condition is determine...

In this paper we examine two methods for using relative contact size as an interaction technique for 3D environments on multi-touch capacitive touch screens. We refer to interpreting relative contact size changes as “pressure” simulation. We conducted a 2 x 2 withinsubjects experimental design using two methods for pressure estimation (calibrated and comparative) and two different 3D tasks (bid...

This paper presents the experimental estimation of ignition pressure value produced by a primer in small arms ammunition. Investigations were performed using chamber capacity equal to 12.7 mm ammunition case. The inner volume was adjusted free cartridge inserting sleeve or glass balls diameter 2 4 mm. values measured inside after action primer. maximum used as an value. Depending on nature fill...

Abstract To overcome limitations of currently used blood pressure measurement devices in accuracy, continuity and comfort, we propose an approach for estimation from electrocardiogram (ECG) signals only. Thereby, statistical signal features are extracted the ECG which, eventually, serve as input to a random forest regression. The method is trained tested on MIMIC III waveform data with large ra...
