Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Academic Paper from the year 2019 in the subject Computer Science - General, grade: 4.0, , language: English, abstract: This review describes or analyses the trends and best practices in Human Computer Interaction and Computer Vision. Human-Computer…Interaction (HCI) is a computer user interface which the user of the system works with to achieve their given tasks and sees the system in use. Information Technology (IT) is essentially an integrated person-machine system that provides information support operations, management and decision-making. Human Computer Interaction (HCI) focuses on the interactions between human and computer systems to achieve the IT system functionality, user experience, usability, the support of user interaction effectiveness. Users are increasingly preferring the use of online business systems and so are becoming intolerant of systems which are not user friendly. The human factor is an attribute (physical or cognitive) which is specific to people that use a system and how it influences the normal operations of the system as well as the achievement of human-environment equilibriums. Surface technology eliminates input/output devices through a touch sensitive feature which plays the role of input/output devices as a result of the merger between the physical and the virtual world. Through surface technology, the user eliminates the use of GUI mediums and reduces the gap between the physical and the virtual world.There are two classes of surface technology, one for the display and the other one which uses a touch sensitive mechanism for the interpretation of user signals. New approaches and methods are now needed in HCI to equip researchers with a better understanding of designing interactive systems. There are new interactive possibilities to be explored in audio-based mobile technology. The increasing popularity of smartphones has proved the portability, adaptability and 'always on' capability of geo-locative interactive systems. HCI bridges the gap between humans and computing devices with respect to observation of interactions, analysis of the involved interactions and the the human consequences of the interaction. The focus of HCI is the practice of usability which includes look-and-feel features, appeal, utility, efficiency, effectiveness and safety.

Druck auf Anfrage Neuware - Printed after ordering - Academic Paper from the year 2019 in the subject Computer Science - Theory, grade: 4.00, ( Atlantic International University ), language: English, abstract: The paper presents an analytical exposition, a critical context, and an integrative conclusio…n on the six major text books on Algorithms design and analysis.Algorithms form the heart of Computer Science in general. An algorithm is simply a set of steps to accomplish or complete a task that is described precisely enough that a computer can run it. It is a sequence of unambiguous instructions for solving a problem, and is used for obtaining a required output for any legitimate input in a finite amount of time. Algorithms can be considered as procedural solutions to problems where the focus is on correctness and efficiency.The important problem types are sorting, searching, string processing, graph problems, combinatorial problems, geometric problems, and numerical problems.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Academic Paper from the year 2021 in the subject Business economics - Business Management, Corporate Governance, grade: 4, , language: English, abstract: The book under review titled ¿How to become a successful entrepreneur in Africa: A Practical Gui…de and Cases Book Review¿ was authored by Emeritus Professor John Kuada and Professor Madei Mangori (2021).The book covers the principles in Part One, about 15 case studies from Botswana, Ghana, South Africa and Zimbabwe, and the selected profiles of the business entrepreneurs are shown in Part Three. Part Two of the book is centred on the profiles of successful African entrepreneurs and stories of various business people.The book is quite rich in principles and integration of competence skills required in establishing and growing a business. The authors suggested a winning strategy. An alternative approach to the research methodology includes the integral research architecture comprising empirical phenomenology, storytelling, grounded theory, and case study.A Social business dimension is proposed to lift up the level of development in the disadvantaged communities, so that the success of the entrepreneurs will also lift up the standard of living of the neighboring communities.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Document from the year 2019 in the subject Computer Science - Internet, New Technologies, grade: 4.00, ( Atlantic International University ), language: English, abstract: The paper presents an analytical exposition, critical context and integrative c…onclusion on the trends and best practices in Information Technology Management, and reviews and evaluates the key issues, trends and future direction of Modern Information Technology Management. IT is generally accepted as a key enabler of economic and technological growth.Managers implement new technology to change something: the organization, the nature of work, relationships with other organizations, or some other facet of business. Information Technology (IT) plays a vital role in leveraging productivity and efficiency in private organizations, governments and research. The value of IT in any organization depends on its infrastructure, which consists of computers, network and telecommunication technologies, data and core software applications. Information Technology (IT) is now a force and driver of modern technological development and globalization, and makes the management of information more efficient and effective. Technology management entails all management activities that determine the application of policy, objectives and responsibilities as well as their execution in an organization in terms of planning, allocating resources, organizing and ensuring outcomes that improve processes. The major IT Management issues are: Using technology to design efficient and effective organizations; Developing a plan for information technology in the organization; Using IT as a part of corporate strategy; Taking advantage of interorganizational systems; Deciding on and developing new applications of IT; Reengineering business processes; Adopting special applications; Changing the organization; Managing the IT infrastructure in a time of explosive growth and technological change; Deciding whether and what to outsource; and Deciding how much to invest in IT. Knowledge and skills are a necessary and sufficient condition for technological progress.Developing countries lack enough skilled IT persons who can design, program, install, configure and maintain Information Technology in this constantly changing industry. Accordingly, lack of qualified and globally recognized IT professionals is seriously hampering IT adoption and development. Management Information Systems refer to information management methods tied to the automation or support of human decision making, whereas IT Management refers to the IT related management activities in organizations.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Academic Paper from the year 2019 in the subject Computer Science - Software, grade: A, ( Atlantic International University ), language: English, abstract: This essay describes or analyses the content, style and merit of the developments in Advanced…Complexity Theory.Complex, self-organising, adaptive systems possess a kind of dynamism that makes them qualitatively different from static objects such as computer chips. Complex systems are more spontaneous, more disorderly, more alive than that. In the past three decades, chaos theory has shaken science to its foundations with the realisation that very simple dynamical systems can give rise to extraordinarily intricate behaviour. The edge of chaos is the constantly shifting battle zone between stagnation and anarchy, the one place where a complex system can be spontaneous, adaptive, and alive.Chaos theory is the qualitative study of unstable, aperiodic behaviour in deterministic, non-linear, dynamical systems. It is a specialised application of dynamical systems theory. Chaotic systems require impossible accuracy for useful prediction tasks. Chaos theory often seeks to understand the behaviour of a complex system by reconstructing its attractor, and knowing this attractor gives us qualitative understanding. Chaos theory includes theoretical hypotheses that assert relationships of qualitative (or topological) similarity between its abstract models and the actual systems it studies.Dynamics is used more as a source of qualitative insight than for making quantitative predictions. Its great value is its adaptability for constructing models of natural systems, which models can then be varied and analysed comparatively easily. Chaos theory is the quantitative study of dynamic non-linear system. Non-linear systems change with time and can demonstrate complex relationships between inputs and outputs due to reiterative feedback loops within the system.These systems are predictable but their behaviour is exquisitely sensitive to their starting point. Chaos is a sub-discipline of complexity. Complexity theory is the qualitative aspect drawing upon insights and metaphors that are derived from chaos theory.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Essay from the year 2019 in the subject Computer Science - Theory, grade: 4.00, ( Atlantic International University ), language: English, abstract: The paper presents an analytical exposition, critical context and integrative conclusion on the discus…sion on the meaning, significance and potential applications of theoretical foundations of computer science with respect to Algorithms Design and Analysis, Complexity Theory, Turing Machines, Finite Automata, Cryptography and Machine Learning.An algorithm is any well-defined computational procedure that takes some value or sets of values as input and produces some values or sets of values as output. A Turing machine consists of a finite program, called the finite control, capable of manipulating a linear list of cells, called the tape, using one access pointer, called the head. Cellular automata is an array of finite state machines (inter-related).A universal Turing machine U is a Turing machine that can imitate the behavior of any other Turing machine T. Automata are a particularly simple, but useful, model of computation which were were initially proposed as a simple model for the behavior of neurons. A model of computation is a mathematical abstraction of computers which is used by computer scientists to perform a rigorous study of computation. An automaton with a finite number of states is called a Finite Automaton (FA) or Finite State Machine (FSM).The Church-Turing Thesis states that the Turing machine is equivalent in computational ability to any general mathematical device for computation, including digital computers. The important themes in Theoretical Computer Science (TCS) are efficiency, impossibility results, approximation, central role of randomness, and reductions (NP-completeness and other intractability results).

Taschenbuch. Zustand: Neu. Neuware - Academic Paper from the year 2021 in the subject Computer Sciences - Cryptocurrency, grade: 1.0, , language: English, abstract: The study was purposed to develop the model structure for Blockchain technology and cryptocurrency, and determine the factors that influence the adoption of Blockcha…in technology and cryptocurrency in Zimbabwe in order to make value-adding contributions to the cybersecurity risk management of the financial services sector. Cybersecurity is the collection of policies, techniques, technologies, and processes that work together to protect the confidentiality, integrity, and availability of computing resources, networks, software, programs, and data from attack. Cybersecurity threats have thus shifted from the cryptocurrency to attacking platforms using the cryptocurrency such as crypto exchanges. Essentially, there would be no bitcoin without Blockchain but Blockchain exists without bitcoin.The entire system works with a distributed ledger technology that operates on a decentralized pattern. The blockchain is distributed and highly available, exhibits irreversibility and immutability, and eliminates intermediaries in banking sector. For the Blockchain to function fully, it requires components such as the Node, Transaction, Block as a data structure, Chain of the blocks, Miners to perform the block verification process, and Consensus (consensus protocol). The Mixed Method methodology was used. The research utilized focus groups and document analysis to gather knowledge on the subject. A survey was conducted which included distribution of questionnaires and conducting interviews with heads of the banking sector.
