Multimedia streaming applications consume significant amounts of server and network resources due to the high bandwidth requirements and long durations of audio and video clips. For popular videos, periodic broadcast techniques exploit the client’s buffer space and network reception bandwidth capabilities to reduce server and network transmission bandwidth requirements. In this paper, we system...

ÐIn this paper, we propose new routing schemes to perform all-to-all personalized communication (or known as complete exchange) in wormhole-routed, one-port tori. On tori of equal size along each dimension, our algorithms use both asymptotically optimal startup and transmission time. The results are characterized by several interesting features: 1) the use of gather-scatter tree to achieve opti...

TCP Slow Start exponentially increases the congestion window size to detect the proper congestion window for a network path. This often results in significant packet loss, while breaking off Slow Start using a limited slow start threshold may lead to an overly conservative congestion window size. This problem is especially severe in high speed networks. In this paper we present a new TCP startu...

This study provides a new permanent magnetic eddy current drive system to solve the energy-saving problem of scraper conveyor working under bad conditions, including overload startup, severe abrasion and pollution. Considering practical conveying conditions chain on fully mechanised coal mining face, this creates mathematical model for based its characteristics indicates motion driven by two wh...

The emergence of real-time applications, like Voice over IP and video conferencing, in IP networks implies a challenge to the underlying infrastructure. Several real-time applications have requirements on timeliness as well as on reliability and are accompanied by signaling applications to set up, tear down and control the media sessions. Since neither of the traditional transport protocols res...

The modern market environment is an of variability and threats that constantly challenges those who operate in it. COVID-19 pandemic has negatively affected all economic processes, without exception, the states world. Its consequences are: increase number unemployed, bankruptcy small medium-sized businesses, disruption supply chains, etc. most sensitive to any changes are business startup proje...
