This paper proposes a new optimization technique called the African Buffalo Optimization. The African Buffalo Optimization (ABO) draws its inspiration from the behavior of African buffalos in the vast African forests and savannahs. African buffalos are a wild species of domestic cattle and are always mobile tracking the rainy seasons in different parts of Africa in search of lush green pastures to satisfy their large appetites. Our interest is in their organizational ability through two basic sounds in search of solutions. Experiments carried out using this novel algorithm in solving some benchmark Travelling Salesman's Problem when compared with the results from some popular optimization algorithms show that the ABO was not only able to obtain better solutions but at a faster speed.

Concurrent adoption of software engineering process improvement frameworks have been widely practiced by the software organizations. The software development organizations leverage these frameworks to better address process improvement challenges. This paper develops an integrated framework for software engineering process improvement practices and unifies the theories in process definition and establishment. The unified framework provides a set of formal descriptions for software engineering process improvement frameworks. Requirements and architectures for software engineering process improvement frameworks are investigated. The main challenge in the integration is the interoperability of the frameworks. Inaccurate integration approach results in inefficiency of the integration process. Common interoperability issues in the integration of current process models and methodologies are addressed. In addition to this, omissions, differences and gaps can be identified and further examined for development of new unified framework. Taxonomy for software engineering process framework is used to support the understanding and comparison of diverse software quality frameworks. The taxonomy should be based on discipline-specific framework. Besides, other alternative approaches for comparing the software engineering process improvement framework are presented. The research outcome is expected to identify the structural relationships among the frameworks. Derivation from the taxonomy includes characteristics and categories of attributes tailored to the discipline-specific framework. © 2011 IEEE.

The wide spectrum use of mobile devices has brought numerous opportunities to develop and design Mobile Learning(M-learning) applications that will assist learners in their studies. From the Mlearning perspective, in order to improve the learners' capabilities through the use of mobile devices, Knowledge Management(KM) processes(Knowledge Acquisition, Knowledge Sharing, Knowledge Application, and Knowledge Protection) should be incorporated in M-learning applications. The literature shows that several research studies were carried out with the aim of developing M-learning applications. Due to the lack of literature on examining the impact of KM processes on M-learning acceptance theoretically and practically, the main objective of this study is to develop a M-learning application that enables KM processes(Acquisition, Sharing, Application, and Protection). Moreover, the paper describes the M-learning application framework that was developed based on KM processes. In addition, the paper deliberates the implementation of the application in two different universities in two different regions, namely: Universiti Malaysia Pahang(UMP) in Malaysia, and Al Buraimi University College(BUC) in Oman. Other implications and discussions are also presented in the paper.

software project success depends on various reasons including project control, software standards and procedures. software development organizations realize the importance of using best practices to improve software development practices. An increasing number of literature have described about process improvement best practices and standards. Formal process improvement frameworks have emerged widely to promote the use of systematic processes for software engineering. These approaches identify best practices for managing software engineering quality. They provide methods for assessing an organization's process maturity level and capability. In this article, recent process improvement best practices and standards are presented. Its objective is to analyze the existing approaches towards software process improvement initiatives. Another objective is to determine the issues related to adoption of process improvement and standards. The research outcome is to obtain the significant process improvement issues and formulate a classification of generic steps for process improvements. © 2011 IEEE.

Unnecessary handoff is one of the key issues in mobile wireless network, since it consumes the network's resources that degrades the performance of the network. Handoff appears when the Receive Signal Strength (RSS) of a mobile node becomes below threshold value (i.e., an acceptable level of RSS for ensuring communication). Subsequently, the mobile node starts scanning to discover a new RSS from neighbors Access Point (AP) to keep continuing the communication. However, traditional handoff algorithm is not accurate due to only depend on the RSS. It is affected by many factors (e.g., shadowing, scattering, reflection, etc.) that initiate unnecessary handoff decision. In this paper, a new technique is proposed to mitigate the unnecessary handoff. The simulation result confirms the effectiveness of the proposal.

Anaphora resolution (AR) is a process to identify the appropriate antecedent with its anaphor which occur before the anaphor. AR able to improve most of the NLP applications such as question answering, short answer examination system and information extraction. Most of AR systems are deal with English language. Thus, in 1990's the research on AR has been applied for other language, such as Arabic, Chinese, Hindi and Norwegian. There are however limited or no effort in dealing with Malay text. The AR systems for one language cannot be simply adapted to use in other languages. This is due to the fact that different languages have different set of rules relating to syntax and semantic to respective language. This paper proposed a model for resolving anaphora phenomena in Malay text. The model consists of three elements consisting of anaphora resolution process, syntactic knowledge process and semantic-world knowledge process. The elements are defined based on the observable fact occurring in Malay language. © 2010 IEEE.

Self-Optimizing Memory Controllers present a great potential in the future of memory controllers. As they alleviate the burden of designing an optimal memory scheduling policy, while providing adaptability to different workloads and systems. Previous state-of-art controllers scheduled memory accesses on the command level. This causes the agent to lose sight of the relation between commands and can lead to the issuing of unuseful sequences of precharge/activate of rows or closing banks that should have been left open, and vice versa. In this work we propose a bank-aware self-optimizing memory controller that schedules memory references on the request-level, presenting to the agent the actual problem it needs to tackle. This simplifies the evaluation of system attributes and eliminates the need for correction mechanisms that was needed in previous controllers. With the proposed algorithm a maximum of 18% increase in the data bus utilization is achieved compared to the commonly used FR-FCFS algorithm. © 2022 IEEE.

The design and deployment of efficient vehicle-to-vehicle (V2V) communications systems require the knowledge of the propagation channel in which it will operate. Due to the mobility of the transmitter/receiver terminals as well as the existence of dynamic scatterers, the V2V channel is nonstationary. To account for the nonstationarity, channel characterization methods that employs the non wide-sense stationary uncorrelated scattering (non-WSSUS) approach are often desired. More also the inadequacy of the Doppler shift operator to properly account for frequency variation effects by the wideband channel operator implies that the time-frequency characterization methods that employ the Doppler shift operator are not appropriate for wideband V2V channels. In this paper we present the time-scale domain characterization of the non-WSSUS channel which employs time scaling operator to account for frequency variation and also emphasizes on the non-stationary property of the channel. The non-WSSUS statistical property termed local sense stationary uncorrelated scattering (LSSUS) is employed. The effect of the channel nonstationarity on the channel capacity is also addressed. From the simulated example, it is inferred that the assumption of ergodic capacity depend on the number of available independent fades which invariably depend on the degree of the V2V channel nonstationarity. © 2010 IEEE.

Since its first appearance in December 2019, Covid-19 has become a wide field of scientific research. Starting from biology to bioinformatic solutions, Artificial Intelligence has contributed in turn as a powerful tool for tracking and predicting the outbreak of Covid-19 using different types of datasets. Chest X-ray images are widely used in computer vision applications and Time series datasets are used for predicting the spread of the novel coronavirus. Graph analytics is a recent field of study that links the mathematical definition and operations of a graph to its application in computer science as a complex data structure, this combination has played a critical role in making graph-based applications present in different fields. One of the most powerful graph analytics is community detection which is an intelligent and unsupervised grouping of a set of graph structured data using the similarity between them. The aim of this work is to highlight the importance of graph-based algorithms in tracking Covid-19 using time series datasets, our work will also focus on Spectral Clustering (SC) as a community detection approach to extract clusters from the input datasets. Further applications are needed in order to validate the proposed theoretical approach. © 2020 IEEE.
