 E-libraries is also known and referred by various authors as either Virtual libraries or Digital libraries. Our society is currently witnessing a quick and continues transformation powered by ICT revolution which has find its way in all other field of human endeavors. The use of information and communication technology (ICT) is becoming an integral part of education in all parts of the globe. Nigeria which Ebonyi is one among the 36 states is not left behind as ICT gradually finds its way into her educational systems regardless of persistent restrictions caused by our low economic status, the increasing numbers of E-libraries even in the young state like Ebonyi stands so encouraging. The advancement of E-libraries has ensured the emergence of global networked environment that has dramatically changed the face and operation of the old traditional libraries’ functions, services including their storage and delivery systems.This paper after reviewing related literature works concerning libraries and its advantages,highlighted several challenges of E-library services in Tertiary institutions in Ebonyi state.Finally,it concludes that if E-libraries in tertiary institutions in the state are to survive, drastic and progressive action needs to be taken by Governments and sponsoring bodies to overcome some of the mentioned challenges.

The purpose of this study is to provide new insights into the factors that influence cancellation behaviour with respect to hotel bookings. Cancellations of bookings are one of the most common concerns in the hotel sector. Before the specified arrival date, the client would cancel their reservation. The cancellation has had a major impact on hotel operations as well. The researchers developed a prototype system called Automated Hotel Booking Cancellation that can assist a hotel in better anticipating consumer cancellations and booking transactions. The researchers utilized a survey questionnaire following the ISO 25010 Software Quality Standard to assess the system's usefulness, functionality, accuracy, security, reliability, and maintainability. The results show "strongly agree" in all the domains with an overall mean = 3.46. IT Experts and respondents evaluated the proposed prototype and gained a "Strongly Agree" rating in all the domains under the survey. The domain on the usefulness of the system gained the highest mean = 3.89 with an interpretation of "strongly agree," and the lowest was the domain of security with a mean = 3.15 or "strongly agree," which ranked 6 in summary.

The researchers concluded based on the findings that the developed prototype web-based system was useful and functional to the needs of the target users/beneficiaries. The user interface of the web-based system was user-friendly, representing an object-oriented user interface for the users. An improvement recommended on the cancellation to automatically predict cancellations that can be incorporated into the system using Machine Learning Algorithms to ease the process of cancellation were recommended for future researchers who want to pursue advanced studies about the topic.

The flexible architecture offered by cloud computing allows for the dispersion of resources and data over numerous places, making it possible to access them from a variety of industrial settings.  The use, storage, and sharing of resources such as data, services, and industrial applications have all changed as a result of cloud computing. In the past ten years, companies have quickly shifted to cloud computing in order to benefit from increased performance, lower costs, and more extensive access. Additionally, the internet of things (IoT) has significantly improved when cloud computing was incorporated. However, this quick shift to the cloud brought up a number of security concerns and challenges. Traditional security measures don't immediately apply to cloud-based systems and are occasionally inadequate. Despite the widespread use and proliferation of various cyber weapons, cloud platform issues and security concerns have been addressed over the last three years. Deep learning's (DL) quick development in the field of artificial intelligence (AI) has produced a number of advantages that can be used to cloud-based industrial security concerns. The following are some of the research's findings: We provide a detailed evaluation of the structure, services, configurations, and security fashions that enable cloud-primarily based IoT. We additionally classify cloud protection dangers in IoT into four foremost areas (records, network and carrier, programs, and gadgets). We discuss the technological issues raised in the literature before identifying key research gaps. In each class, describe the boundaries using a popular, artificial intelligence, and in-depth studying attitude. and security concerns relating to individuals), which are fully covered; we find and analyze the most recent cloud-primarily based IoT attack innovations; we identify, talk, and verify key safety challenges show the regulations from a standard, synthetic intelligence, and deep learning perspective in every class angle; we first present the technological difficulties identified in the literature before identifying IoT-based cloud infrastructure has significant research gaps which should be highlighted for future research orientations. Cloud computing and cyber security.

Altera SDK for OpenCL allows programmers to write a simple code in OpenCL and abstracts all Field programmable gate array (FPGA) design complexity. The kernels are synthesized to equivalent circuits using the FPGA hardware recourses: Adaptive logic modules (ALMs), DSPs and Memory blocks. In this study, we developed a set of fifteen different benchmarks, each of which has its own characteristics. Benchmarks include with/without loop unrolling, have/have not atomic operations, have one/multiple kernels per single file, and in addition to one/more of these characteristics are combined.  Altera OpenCL v14.0 adds more features compared with previous versions. A set of parameters chosen to compare the two OpenCL SDK versions: Logic utilization (in ALMs), total registers, RAM Blocks, total block memory bits, and clock frequency.

Quality of queuing service management is the aim of any organization providing its services to customers. The purpose of this paper is to evaluate the factors affecting the quality of service provided by the public sector depending on waiting lines. For this purpose, a questionnaire survey was conducted on a sample of 394 to collect data relating to customer satisfaction. The questionnaire consists of five factors: process, tangible, responsiveness, reliability, and empathy. The results showed that the degree of agreement of the factors; process, tangible, reliability, responsiveness, empathy, and service quality gain a neutral category, and all the factors have statistically significant effects on quality of service except the empathy factor. For the demographic information, the results showed that there are statistically significant differences for most of the demographic information. This paper extends the previous research that investigates factors affecting e-recruitment. The author extends the results of previous research related to the transparency of e-recruitment. The study recommended the service departments should make more effort in the way of providing services to improve the level of service quality management.

The SBM Robot is a manually operated robot focused on the Internet of Things and the robot operating system. The system is focused on washing and maintenance. The robot is controlled by an android app that uses the Google Real Time Firebase database to control the robot. HVAC duct is small in size and cleaning and repairing the duct is a very difficult task for humans, but it's easy to robot, robot goes inside the duct, and inspects and cleans the duct. Like similar, ships use fuel, oils, sludge, sewage, water and other fluids stored in tanks.
