A new theoretical method for computing travel distance, number of turns, and cyclone pressure drop has been developed and is presented in this article. The flow pattern and cyclone dimensions determine the travel distance in a cyclone. The effective number of turns was calculated based on the travel distance. Cyclone pressure drop is composed of five pressure loss components. The frictional pre...

Exhumation has been recognized as an important problem in tectonics and can be achieved by normal faulting, ductile thinning, and erosion. The exhumation of ultrahigh-pressure (UHP) rocks is the most challenging and least understood aspect of the exhumation problem. In this review, we focus on a variety of geologic settings with the goal of characterizing exhumation rates and maximum depths of ...

Fatigue and driver drowsiness monitoring is an important subject for designing driver assistance systems. The measurement of eye closure is a fundamental step for driver awareness detection. We propose a method which is based on eyelid detection and the measurement of the distance between the eyelids. First, the face and the eyes of the driver are localized. After extracting the eye region, the...

A real-time non-invasive method for mean arterial blood pressure (MAP) estimation is presented. MAP is estimated by effectively combining two components: one describing the low frequency behaviour and one the fast variations of MAP. The method, developed on 20 volunteers under anaesthesia allows for statistically significant improvement with respect to the standard cuff system. This approach re...

Ambulatory blood pressure measurement (ABPM) is being used increasingly in clinical practice. In recognition of this the British Hypertension Society has published recommendations for the use and interpretation of ABPM in clinical practice, and the European Society of Hypertension has published recommendations on blood pressure measuring devices, including devices for ABPM. Importantly, the tec...

This study attempted to identify the factors that affect the pressure pain threshold (PPT) on the heel region of the foot. Using dimensional analysis, it was found that probe area (A), indentation speed (V) and their interaction contribute towards PPT. A power form of these factors can be used to model PPT with an exponent of 0.63.

Phonemic settings and the internal models that they represent are learned in the process of language and speech acquisition. Postural settings, in contrast, rely on continuous auditory monitoring and tend to break down quickly if this monitoring process is inhibited during speech production. Evidence presented in the literature seems to indicate that stable internal models are mostly associated...

In this paper we present initial results in utilization of TPMS (Tire Pressure Monitoring System) for collecting traffic data and deriving traffic information, i.e. travel times. The obtained results show that current detection ratio is less than 5 % and the obtained travel times are in consistency with referent data. The experiment is performed on DLR test track in Berlin. In particular, archi...

To ensure safe and stable drilling operation, bottom hole pressure (BHP) should be kept within some region. However measurement of the BHP is sometimes not available or reliable, especially when the circulation is low, e.g., during pipe connection procedures. This paper presents the application of a moving horizon estimation (MHE) method for online estimation of the BHP during petroleum drillin...
