Monitoring of ECG signal is used in medicine for multiple purposes. Measurements can be taken at any stage of patient's medical care, either as a preventative, diagnostical or recovery monitoring. Current wearable technology enables users and doctors to produce so far unprecedented amount of information. Processing of such measurements is usually a laborious and time consuming manual task. Automatic...
Wireless devices for ambulatory ECG monitoring are becoming increasingly popular. One of the challenges that wireless monitoring has to deal with is clock synchronization between the wireless sensor device and the controller device. The monitoring device is usually kept as simple as possible to maximize its autonomy, and is thus limited in its clock accuracy. In this article, we describe a method...
NevroEkg is a computer application for analysis of ECG and related bio-signals, such as breathing and blood pressure. It was made in collaboration between computer scientists, engineers and neurocardiologists. Recently, it has been modified to also support the unconventional measurements of differential ECG, made on wireless wearable gadgets. These wearable gadgets measure ECG a bit differently —...
The differential ECG measurement is performed by a small gadget attached to a person's chest. In contrast to the standard 12-channel ECG, which is most often short and measured on a resting subject, the small form factor of the gadget allows for several days long measurement of active subjects. The resulting measurements are not only novel in their time and activity coverage, but they also require...
The process of LTE and LTE-A mobile networks optimization for 900 MHz radio signal using the open-source GRASS-RaPlaT tool and evolutionary algorithm is presented. The aim of the proposed solution is to reduce operational costs and to maximize network efficiency. Based on the terrain profile maps and construction locations, the tool calculates path loss by applying state-of-the-art statistical models...
In this paper, the code for the North Atlantic Princeton Ocean Model (NAPOM) used by the Marine Biology Station (MBS) is parallelized and optimized. The FORTRAN source code and the hardware architecture of MBS cluster are examined and analyzed to determine the behavior of the NAPOM execution with bottlenecks identified on both ends. Based on the analysis, the most effective optimization and parallelization...
Biologists have been investigating the plant defense response to virus infections for a long time. Nevertheless, its model has still not been developed. One of the reasons is the deficiency in numerical kinetic data that brings up the importance of the expert knowledge. Therefore, we based our work on acquiring domain knowledge of biological pathways which provided a basis for the construction of...
