Popularity prediction, which aims to forecast how many users would like interact with a target item or online content in the future, can help shopping social media platforms identify popular items digital contents. Many efforts have been made study multi-faceted factors, such as features, user preferences, and influence, affect user-item interactions, but little work has focused on evolutionary dynamics of these factors for individuals groups. In that light, this paper develops...

Video streaming services that provide heterogeneous video quality are required because the usage environments diverse and changing dynamically. Considering characteristics of application, must be distributed without stopping service or deteriorating quality. In order to achieve that, though volume data is too huge, it necessary reduce total storage transmission quantity. this paper, autonomous video-on-demand system architecture for levels an evaluation method reliability proposed. system,...

A new image segmentation algorithm based on Markov random field (MRF) with evolutionary programming (EP) is presented in this paper. As infrared (IR) has blurry edges and fuzzy texture, the of becomes more complicated sophisticated. MRF model an effective way for segmenting image, which been used many processing. However must optimize field, classical optimization simulated annealing (SA) that could get global optimal resolution heavy calculation burden. To avoid unacceptable calculations,...

In global air traffic management (ATM), it is necessary to exchange various information related aircraft operation such as the flight plans, surveillance, airports, weather, and restrictions, among different systems operators. Hence, concept of System Wide Information Management (SWIM) has been promoted by International Civil Aviation Organization (ICAO) implement interoperability harmonization in operation. SWIM environment, all stakeholders need efficiently obtain ATM data with situational...

The System Wide Information Management (SWIM) concept is to change the conventional Air Traffic (ATM) information architecture from point-to-point data exchanges system-wide interoperability. However, how construct local and global SWIM by applying Service Oriented Architecture (SOA) Cloud based technologies still under discussion. In this paper, framework SOA-based construction through an international demonstration are presented.

The concept of System Wide Information Management (SWIM) for global Air Traffic (ATM) is to achieve various information exchange among related stakeholders, such as about flights, routes, surveillance, airports, aircrafts, and weather. Although standard models are adopted in the SWIM concept, these different each type information. Therefore, ontology data-linking technologies required semantic integration heterogeneous data. In this paper, we focus on geospatial contained data, propose a...

Denote by [Formula: see text] (respectively, text]) the largest smallest) prime factor of integer text]. In this paper, we prove a lower bound almost-primes with such that for As an application, study two patterns on factors consecutive integers one which without small factor.

The authors conducted a preliminary feasibility study on applying quantum key delivery (QKD) to future air traffic management systems. We evaluated the number of bits required exchange information needed for systems ensure safety and found that currently feasible QKD generation rate is sufficient daily operations airlines.

To protect the safety of flight operations from cyber threats and ensure business continuity, a trust framework for international aviation that can trusted information exchanged between identities through communication paths has been discussed by International Civil Aviation Organization (ICAO). However, due to security failures affecting safety, not only digital identity network resiliency but also access risk management should be considered. In this paper, capabilities System Wide...

The efficient and reliable information service provision utilization is an important infrastructure in the high-assurance system. In this paper, we introduce a rating oriented distributed system sustained by push/pull mobile agents to cope with providers' users' heterogeneous requirements. Based on environment, autonomous technology proposed. However, when demand changes, congestion might arise order achieve load balancing for timeliness access guarantee that users can always get from...

Under dynamic and heterogenous environment, the need for adaptability rapid response time to information service systems has become increasingly important. In order cope with continuously changing conditions of provision utilization, Faded Information Field (FIF) been proposed. this paper, based on analysis relationship that exists among users distribution, access time, we propose technology FIF design resolve competing requirements providers improve users' time. addition, achieve load...

With the advancement of information and communication technologies, to improve interoperability between heterogeneous systems by regularizing syntax for exchange is essential achieve global seamless air traffic management operation. However, current point-to-point aviation related among different operators cannot satisfy requirement interoperability. The concept System Wide Information Management (SWIM) has been promoted International Civil Aviation Organization (ICAO) implement...
