Attacks on cloud computing (CC) services and infrastructure have raised concerns about the efficacy of data protection mechanisms in this environment. The framework developed study (CCAID: computing, attack, intrusion detection) aims to improve performance detection systems (IDS) operating CC environments. It deploys a proposed new hybrid ensemble feature selection (FS) method. includes FS algorithms three different types (filter, wrapper, embedded algorithms). selected features used train...

Mobile cloud computing (MCC) is a technological paradigm for providing services to mobile device (MD) users. A compromised MD may cause harm both its user and other MCC customers. This study explores the use of machine learning (ML) models stochastic methods protection Android MDs connected cloud. To test validity feasibility proposed methods, adopted proof-of-concept approach developed prototype system named MINDPRESS. The static component MINDPRES assesses risk apps installed on MD. It...

Learning computer programming is a demanding cognitive task that requires number of competencies. Students with limited problem-solving skills or prior knowledge find it challenging to understand the abstract concepts involved. While much research has investigated how load affects learning, few studies have in memory associated tasks using electroencephalograms. This uses EEG data, modelled NeuCube spiking neural network architecture, analyse efficiency two groups students, and without...

Transfer of learning (TL) is the process applying knowledge and skills learned in one context to a new different context. Efficient use memory essential achieving successful TL good outcomes. This study uses cognitive computing approach identify explore brain activity patterns related efficiency programming language. The hypothesizes that prior reduces load, leading improved efficiency. Spatiotemporal data (STBD) were collected from sample participants (n=26) using an electroencephalogram...
