For the detection of the anomalies in the computer and telecommunication networks in “online” mode we propose the method, based on the discrete wavelet decomposition of the traffic and the algorithms of statistical processing, based on the F - test. We use two sliding windows with two threshold values that allow us to guarantee the high efficiency of the detection of the network anomalies' bursts...
An efficient colorization scheme for images based on prioritized source propagation is proposed in this work. A user first scribbles colors on a set of source pixels in an image. The proposed algorithm then propagates those colors to the other non-source pixels. Specifically, the proposed algorithm identifies the non-source pixel with the highest priority, which can be most reliably colorized. Then,...
The growth of the Internet and related technologies has enabled the development of a new breed of dynamic websites and applications that are growing rapidly in use and that have had a great impact on many businesses. These websites need to be continuously evaluated and monitored to measure their efficiency and effectiveness, to assess user satisfaction, and ultimately to improve their quality. The...
This paper reports on the development of a model to improve the understanding of the extent of Enterprise Resource Planning (ERP) system usage in universities. Previous research revealed that university ERP systems are not fully utilized by end-users, resulting in low usage and institutional inefficiencies. This leads to stakeholders particularly students and government pressurizing universities to...
The amount of data stored is rapidly increasing due to consumer, business, scientific, and government generated content. In addition to keeping pace with storing generated data, there is a need to comply with laws and Service Level Agreements (SLA) to protect and preserve stored data. The issues of capacity and scale in data storage are of constant concern to ensure the ability to absorb data growth,...
