Hispano-Arabic Poetry, the Provencal Medium, and Middle English Lyrics: Some Similarities in Their Metrical Patterns, Motifs, Imagery, and Phraseology

In this paper I advance the thesis that certain aspects of HispanoArabic poetry have influenced Medieval English poetry principally by way of the Proven9al poetry of the troubadours and of other European poetries. Although extensive studies have been published on the Arabic theory on the genesis of European vernacular poetry as well as on the influence of the troubadours on Medieval English poetry, no serious study, as far as I can ascertain, has been published showing the link between Hispano-Arabic and Middle English poetry. This thesis, I hope, should make a specific contribution to the field of comparative studies in Medieval European literature by demonstrating that some Hispano-Arabic elements can be seen in Middle English lyrics. The� thesis first discusses the impact of Medieval Arabic culture on Medieval Europe and the means through which the transmission of Arabic knowledge was effected. In it I review the theories on the origins of Romance vernacular poetry and of the courtly love tradition and examine the characteristics of Hispano-Arabic poetry, showing its influence on Romance vernacular poetries, especially on the Proven9al. I also discuss the influence of Provencal poetry on European Medieval poetries including Middle English poetry. Finally, in light of the foregoing discussions, I demonstrate the similarities in metrical patterns and in the motifs, imagery, and phraseology between Hispano-Arabic poetry and Middle English lyrics. However, beyond a few general references, the religio~s poetry is not treated in this study. Again, apart from a few illustrations, the poetic works of Chaucer, Gower, Lydgate, Skelton, and Dunbar are not examined. Such writers need an analysis beyond the scope of this effort. As the study stands, some repetitions of ideas and jargon still appear. Also, apart from the verses reproduced from the English translations of Arabic poetry, I take the responsibility for any deficencies in the few translations I made. For transliteration and unless quoting, I followed the system used by American scholarly journals. In the case of proper names and place names, I used the generally accepted forms in current English scholarship. Some of the words, such as Hispano-Arabic and Andalusian, are used interchangeably. I also normalized medieval English spelling to some extent. For example, the letter (y) is used instead of the yogh (3).Englis

Relationship Between Students’ Learning Outcomes in WAEC and NECO Arabic Language Examinations in North-Central Nigeria

Despite the fact that the certificates being awarded by senior school WAEC and NECO are said to be comparable, yet, stakeholders in the education sector doubt their correspondence in terms of students’ learning outcomes. While some students only register for NECO believing that they could not pass WAEC. This was part of what necessitated this study by determining the correspondence between students’ learning outcomes in senior school WAEC and NECO Arabic Language examinations in North-central from 2015 to 2019 academic sessions. This study was a descriptive study of the correlational type. Only the results of candidates that sat for WAEC and NECO Arabic Language examinations were logically selected for this study via a researcher-designed proforma. Thus, 948 students constituted the sample size for this study using a multistage sampling procedure. Data collected were analyzed using the percentage to answer the research questions while the Pearson’s chi-square at 0.05 alpha level was used to test the hypotheses. Findings indicated that a significant association existed between students’ learning outcomes in WAEC and NECO Arabic examinations in North-central Nigeria. It was therefore recommended that teachers of Arabic should work harder to sustain their students’ performance in Arabic Language

Visualization representation benefits of pre-requirement specification tractability

Representation of Pre-RST information is very useful using visualization elements for realization of benefits of requirements tractability This improves the practitioners motivation to maintain Pre-RST information during life cycle processes. Few researchers proposed visualization for post-RST due to which many benefits of requirements tractability cannot be realized. This paper proposed an important visualization representing Pre-RST information that demonstrate various benefits of requirements tractability. In order to evaluate empirically an experiment is conducted and textual representation of tractability information is obtained. In order to strengthen our claim a survey is conducted to compare textual representation of tractability information with proposed visualization and results are compiled

By way of mitigating this practice, researchers have proposed several solutions for the detection and filtering of SMS spams. In this paper, we present a review of the currently available methods, challenges, and future research directions on spam detection techniques, filtering, and mitigation of mobile SMS spams. The existing research literature is critically reviewed and analyzed. The most popular techniques for SMS spam detection, filtering, and mitigation are compared, including the used data sets, their findings, and limitations, and the future research directions are discussed. This review is designed to assist expert researchers to identify open areas that need further improvement

Analyzing Autoencoder-Based Intrusion Detection System Performance

The rise in cyberattacks targeting critical network infrastructure has spurred an increased emphasis on the development of robust cybersecurity measures. In this context, there is a growing exploration of effective Intrusion Detection Systems (IDS) that leverage Machine Learning (ML) and Deep Learning (DL), with a particular emphasis on autoencoders. Recognizing the pressing need to mitigate cyber threats, our study underscores the crucial importance of advancing these methodologies. Our study aims to identify the optimal architecture for an Intrusion Detection System (IDS) based on autoencoders, with a specific focus on configuring the number of hidden layers. To achieve this objective, we designed four distinct sub-models, each featuring a different number of hidden layers: Test 1 (one hidden layer), Test 2 (two hidden layers), Test 3 (three hidden layers), and Test 4 (four hidden layers).We subjected our models to rigorous training and testing, maintaining consistent neuron counts of 30 and 60. The outcomes of our experimental study reveal that the model with a single hidden layer consistently outperformed its counterparts, achieving an accuracy of 95.11% for NSL-KDD and an impressive 98.6% for CIC-IDS2017. The findings of our study indicate that our proposed system is viable for implementation on critical network infrastructure as a proactive measure against cyber-attacks

Energy-efficient Virtual Machine Allocation Technique Using Flower Pollination Algorithm in Cloud Datacenter: A Panacea to Green Computing

Cloud computing has attracted significant interest due to the increasing service demands from organizations offloading computationally intensive tasks to datacenters. Meanwhile, datacenter infrastructure comprises hardware resources that consume high amount of energy and give out carbon emissions at hazardous levels. In cloud datacenter, Virtual Machines (VMs) need to be allocated on various Physical Machines (PMs) in order to minimize resource wastage and increase energy efficiency. Resource allocation problem is NP-hard. Hence finding an exact solution is complicated especially for large-scale datacenters. In this context, this paper proposes an Energy-oriented Flower Pollination Algorithm (E-FPA) for VM allocation in cloud datacenter environments. A system framework for the scheme was developed to enable energy-oriented allocation of various VMs on a PM. The allocation uses a strategy called Dynamic Switching Probability (DSP). The framework finds a near optimal solution quickly and balances the exploration of the global search and exploitation of the local search. It considers a processor, storage, and memory constraints of a PM while prioritizing energy-oriented allocation for a set of VMs. Simulations performed on MultiRecCloudSim utilizing planet workload show that the E-FPA outperforms the Genetic Algorithm for Power-Aware (GAPA) by 21.8%, Order of Exchange Migration (OEM) ant colony system by 21.5%, and First Fit Decreasing (FFD) by 24.9%. Therefore, E-FPA significantly improves datacenter performance and thus, enhances environmental sustainability
