Although LTE-Advanced system is targeted at enhancing the users’ throughput and increasing connection reliability, however user’s mobility tends to degrade the efficiency of the services and applications in terms of throughput degradation and outage probability reduction. Particularly this is during the handover from the source to the target eNBs. Therefore, the Carrier Aggregation (CA) techniq...

Transient luminous events (TLEs) are electrical discharges in the upper atmosphere caused by vigorous thunderstorms. Six sprites, which part of TLEs, were observed on 22 July 2013 from Mt. Fuji (3776 m above sea level), Japan. All six sprites associated with intense positive cloud-to-ground strikes (+CGs), whose causative charges can reside stratiform region. Consequently, we assumed that main ...

Abstract Multiscale processes from synoptic disturbances to diurnal cycles during the record-breaking heavy rainfall in summer 2020 were examined this study. The consisted of eight episodes, each lasting about 5 days, and associated with two types disturbances. Type-1 episodes featured a northwestward extending western Pacific subtropical high (WPSH), while Type-2 had approaching midlatitude tr...

Both the stratiform and convective regions play important roles in development of mesoscale systems (MCSs). In this study, impacts hydrometeors water vapor region on evolution MCSs during a heavy rainfall event over South China are investigated by Weather Research Forecasting (WRF) model with Thompson microphysics. A series sensitivity experiments including reductions to 95%, 80% (water experim...

The hypothesis that inertial instability plays a role in the upscale development of mesoscale convective systems (MCSs) is explored by sampling environments that supported the growth of MCSs in the Preliminary Regional Experiment for STORM (Stormscale Operational and Research Meteorology) (PRE-STORM) network with high quality special soundings. Secondary circulations that occurred in the presen...

Oceanic tropical clouds are observed to occur at various length scales over the equatorial trough zone (an area around the intertropical convergence zone or ITCZ). As one proceeds from the subtropics towards the equator, the cloud types range from small stratocumulus, small cumulus (including trade cumulus), cumulus, cumulonimbus (isolated) and large mesoscale convective systems (MCSs)with a co...

This study examines the characteristics of a large number of extreme rain events over the eastern two-thirds of the United States. Over a 5-yr period, 184 events are identified where the 24-h precipitation total at one or more stations exceeds the 50-yr recurrence amount for that location. Over the entire region of study, these events are most common in July. In the northern United States, extr...

The advancement in wideband wireless network supports real time services such as IPTV and live video streaming. However, because of the sharing nature of the wireless medium, efficient resource allocation has been studied to achieve a high level of acceptability and proliferation of wireless multimedia. Scalable video coding (SVC) with adaptive modulation and coding (AMC) provides an excellent ...

Multiple Classifier Systems (MCSs) have been widely used in the area of pattern recognition due to the difficult task that is to find a single classifier that has a good performance on a great variety of problems. Studies have shown that MCSs generate a large quantity of classifiers and that those classifiers have redundancy between each other. Various methods proposed to decrease the number of...

Multi-Classifier Systems (MCSs) have fast been gaining popularity among researchers for their ability to fuse together multiple classification outputs for better accuracy and classification. At present, there is a lot of literature covering many of the issues and concerns that MCS designers encounters. However, we found out that there isn’t a single paper published thus far which presents an ov...
