BACKGROUND Because the movement of stock prices is not only ubiquitous in financial markets but also crucial for investors, extensive studies have been done to understand the law behind it. In particular, since the financial crisis in 2008, researchers have a more interest in investigating large market volatilities in order to grasp changing market trends. METHODOLOGY/PRINCIPAL FINDINGS In th...

Low latency and high availability of an app or a web service are key, amongst other factors, to the overall user experience (which in turn directly impacts the bottomline). Exogenic and/or endogenic factors often give rise to breakouts in cloud data which makes maintaining high availability and delivering high performance very challenging. Although there exists a large body of prior research in...

Drilling a hole into rock results in stress concentration and redistribution close to the hole. When induced stresses exceed strength, wellbore breakouts will happen. Research on breakout is fundamental of stability. A sequence concentrations, falling, redistributions, which involve initiation, propagation, stabilization sequences. Therefore, simulating process very challenging. Thermoporoelast...

Knowledge of the orientation of horizontal in situ stresses is important to some areas of oil and gas field development plans. Borehole breakouts observed in image logs and drilling-induced fractures are the main parameters for the determination of the stresses’ directions in situ. In this work, the orientations of borehole breakouts were investigated as a function of depth in oil wells A and ...

Fire alarm system consist of several type sensors that works togeher in order to detect a fire breakouts. But the systems itself errors especially detecting smoke which sometimes could not lead potential breakouts instead causing false alarm. Moreover, vision cameras are expensive be installed and it takes lot amount money for maintenance alone. This causes many household does equip with such d...
