background and objective: cerebral arteriovenous malformation (cavm) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in arteriovenous malformation patients. the vessel geometry in cavm patients are...

The objective of this study was to investigate the effect of microbial oil on rumen fermentation of a diet composed of 60% hay and 40% barley in an artificial rumen (Rusitec). Microbial oil (MO) was produced by the fungus Thamnidium elegans. This fungus grew on the wheat bran/spent malt grains (3:1) mixture. The fatty acid composition of microbial oil was as follows: 0.7% C14:0, 15.4% C16:0, 10...

background and objective: the circle of willis (cow) supports adequate blood supply to the brain. the cardiovascular system, in the current study, is modeled using an equivalent electronic system focusing on the cow. method: in our previous study we used 42 compartments to model whole car- diovascular system. in the current study, nevertheless, we extended our model by using 63 compartments to ...

According to the World Health Organization (WHO) data, heart diseases are among with highest mortality rate. Cardiovascular diseases, known as cardiovascular defined formation of plaque on inner wall vessel, hardening vessels, narrowing vessel and making blood flow difficult. The diagnosis disease is made by examining various clinical findings. findings tests take time, prolonging diagnostic ph...

Background: Aim of the study was to test accuracy AI-based software for detection large vessel occlusion (LVO) with computed tomography angiography (CTA) in stroke patients using an experienced neuroradiologist’s evaluation as reference. Methods: Consecutive who underwent multimodal brain CT suspected acute ischemic were retrospectively identified. The presence and site (classified proximal dis...

Abstract Artificial intelligence is an enabling technology for autonomous surface vehicles, with methods such as evolutionary algorithms, artificial potential fields, fast marching methods, and many others becoming increasingly popular solving problems path planning collision avoidance. However, there currently no unified way to evaluate the performance of different example regard safety or ris...

This case report discusses a case of aseptic osteonecrosis in a cranioplasty bone flap after decompressive craniectomy, which is a known, but rare complication after autologous cranioplasty. We suggest that the pathophysiology of cranial bone flap necrosis may have a similar pathophysiology to free flap necrosis/failure. The key suggested problem causing the osteonecrosis is vessel thrombosis w...

This paper describes the procedure developed at MARINTEK for the automatic optimisation of hull lines to reduce the ship resistance as well as the wake wash generated by a ship within the given constraints. The methodology, developed computer programs and used constraints are described. The methodology is exercised using lines of a fast ship. A numerical comparison is performed between the resi...

Microparticle image velocimetry (μPIV) is an evolving quantitative methodology to closely and accurately monitor the cardiac flow dynamics and mechanotransduction during vascular morphogenesis. While PIV technique has a long history, contemporary developments in advanced microscopy have significantly expanded its power. This chapter includes three new methods for μPIV acquisition in selected em...
