Abstract: In recent years widespread fake news has given rise to several social and political problems. Most of the knowledge today is acquired from digital sources. In Digital media it's difficult to assign accountability to the opinion thanks to which the info received can't be authenticated. Since the extent of ecological and societal issues, machine learning is especially relevant within the perspective of fake messages in Social Media. Anyone can make a message viral which may be a fake or real one. The goal is to understand a mechanism that's automatic, robust, reliable and efficient, despite various challenges which may help for the efforts to progress. In this i present the review on the state-of-the-art of faux news detection mechanisms on social media. After we discuss the background of the issues that are surrounding fake news and therefore the impacts it's on the users. We further discuss on different approaches presented in categories like the content-based, social context-based and hybrid-based methods. We conclude the paper with four keys of open research challenges which will guide the longer term research.

Keywords: Fake news detection, Sentence matching, Natural language processing, deep learning, and Word embedding, tf-idf, Sentiment, Machine Learning, Convolution Neural Networks, NLP, and Sentence Classification.

Abstract: Timely verification of security requirements for new network devices is crucial to maintain the security and protection of the enterprises’ assets. This is due to the fact that insecurely configured or inadequately patched network devices deployed into a production environment may be exploited for unauthorized/malicious use. This paper will shed some light on the importance of timely security assessment against network devices and appliances and will explore the most efficient approach into addressing this requirement.

Keywords: automation, network devices, appliances, security, cybersecurity, assessment, security configurations.

Abstract: Multi-pixel encoding is an emerging method in visual Krystal for that it can encode more than one pixel for each run. However, in fact its encoding efficiency is still low. This paper presents a novel multi- pixel encoding which can encode variable number of pixels for each run. The length of encoding at one run is equal to the number of the consecutive same pixels met during scanning the secret image. The proposed scheme can work well for general access structure and chromatic images without pixel expansion. The experimental results also show that it can achieve high efficiency for encoding and good quality for overlapped images.

Keywords: Visual secret sharing, cheating immune, anonymity.

Abstract: This research paper is directed at improving the Replication Overhead of Microsoft Exchange Mailbox Databases in a Database Availability Group for Mid-to-Large sized organizations while not compromising on the High Availability and resiliency of the email service. There are many aspects of a healthy Microsoft Exchange email landscape, yet the one factor which is often ignored is the number of Mailbox Database copies that are managed and maintained by an Organization. The larger an organization, the more complex the email environment, resulting in dependency on Hardware and constant stress due to increase in demand. Validating the Replication Threads for each Exchange Mailbox Server and reducing the number of Copies may be the solution until a new environment is commissioned that addresses the stress pain points. The primary goal of this research paper is to improve upon the reliability and stability of an enterprise email environment, which increases user productivity through improved system response and availability.

Keywords: Replication Performance, Microsoft Exchange Database.

Abstract: The age of intelligent machines has arrived, and conversational interfaces are leading the charge. Over the past couple of years, we have been swarmed by a number of new kinds of machines and software collectively known as bots. Bots are automated hardware or software machines that are powered by the advances in Artificial Intelligence (AI) technologies. Recent developments in machine learning algorithms, such as deep learning and deep reinforcement learning, have improved the performance of AI tasks such as Automatic Speech Recognition (ASR), Natural Language Understanding (NLU), Text to Speech Synthesis (TTS), and Image Recognition. This has accelerated humankind's journey toward the technological singularity, the point in time when AI surpasses natural human intelligence by leaps and bounds.

Abstract: In the present work, specifications of Ghana Research Reactor 1 (GHARR-1) were adopted for modelling purpose to mimic the MNSR generic design. To ensure consistency in simulated results, GHARR-1 was equally used to experimentally generate data on the inlet and outlet temperatures of the reactor core at varying coolant flow rates for later used to simulate initial conditions of the thermal hydraulic code. The numerical values of flow parameters as contained in GHARR-1 Safety Analysis Report (SAR) were used to further condition the code and also to validate the convergence at the output stage. The model utilized 90% enriched U-235 to produce neutron flux of up to 1x10¹² cm^-2s^-1 at a corresponding thermal power output of 31 kW.  The core coolant modelling and simulation wereachieved using  Simulation of Turbulent flow in Arbitrary Regions Computational Continuum Mechanics C++ based (STAR CCM+) Computational Fluid Dynamics (CFD) code.  The code successfully analyzed the progression of flow parameters from the inlet to the outlet of the reactor core. Thermal hydraulic studies of the reactor core coolant is necessary for safety of evaluation of a nuclear reactor.

Keywords: STAR-CCM+, CFD, GHARR-1, core coolant, flow rates, thermal flux, thermal power, MNSR.

Abstract: Digital is the new normal. The emergence and evolution of the information technology (IT) and digital helps many organizations especially enterprises to achieve their business model targets. The evolution of the information technology (IT) and digital, somehow, realized many organizations to enhance or change their existing traditional business model to become more digitalized. Organizations should leverage the information technology to sustain their enterprise and adapt innovative business models align with the new normal. The existing emergence of new start-up organizations with innovative business models, and the re-positioning of incumbent organizations with innovative business models and digital transformation have created fierce competition in the market place. Thus, forcing organizations to change and transform their business models and strategies as well. Hence, the new digital transformation strategy brings new enterprise risks, unique challenges and opportunities.  It is important for each organization, nowadays, to have an Integrated Enterprise Risk Management (IERM) that integrated with the information technology that help their businesses becoming more successful. This paper offers IERM business model for a telecommunication company with focus on achieving business plan objectives and goals, and integrating the ISO 27000 Information Security Management System (ISMS) standards and ISO 31000 Risk Management. The design thinking approach has been adapted in the paper to understanding the challenges of telecommunication companies to formulate and recommend a business models for an Integrated Enterprise Risk Management (IERM). This recommendation includes identifying of strategic assets and associated risks, suggested and identified mitigation actions for strategic assets with high risks and enhance the control mechanism. This should be done by building conceptual business model using modelling tool such as Business Modal Canvas (BMC). The approach includes conducting literature review, bench marking, and interviews for understanding and managing the high risks in implementing the business plan successfully, by formulating an (IERM) for telecommunication industry. The recommendation is to offer assistance to telecommunication-related organizations navigate a digital risk transformation, now and in the long term. This includes identifying of strategic assets and associated risks, suggested and identified mitigation actions for strategic assets with high risks and enhance the control mechanism.
