Factors shaping the evolution of electronic documentation systems
The main goal is to prepare the space station technical and managerial structure for likely changes in the creation, capture, transfer, and utilization of knowledge. By anticipating advances, the design of Space Station Project (SSP) information systems can be tailored to facilitate a progression of increasingly sophisticated strategies as the space station evolves. Future generations of advanced information systems will use increases in power to deliver environmentally meaningful, contextually targeted, interconnected data (knowledge). The concept of a Knowledge Base Management System is emerging when the problem is focused on how information systems can perform such a conversion of raw data. Such a system would include traditional management functions for large space databases. Added artificial intelligence features might encompass co-existing knowledge representation schemes; effective control structures for deductive, plausible, and inductive reasoning; means for knowledge acquisition, refinement, and validation; explanation facilities; and dynamic human intervention. The major areas covered include: alternative knowledge representation approaches; advanced user interface capabilities; computer-supported cooperative work; the evolution of information system hardware; standardization, compatibility, and connectivity; and organizational impacts of information intensive environments
Genetic Programming for Smart Phone Personalisation
Personalisation in smart phones requires adaptability to dynamic context
based on user mobility, application usage and sensor inputs. Current
personalisation approaches, which rely on static logic that is developed a
priori, do not provide sufficient adaptability to dynamic and unexpected
context. This paper proposes genetic programming (GP), which can evolve program
logic in realtime, as an online learning method to deal with the highly dynamic
context in smart phone personalisation. We introduce the concept of
collaborative smart phone personalisation through the GP Island Model, in order
to exploit shared context among co-located phone users and reduce convergence
time. We implement these concepts on real smartphones to demonstrate the
capability of personalisation through GP and to explore the benefits of the
Island Model. Our empirical evaluations on two example applications confirm
that the Island Model can reduce convergence time by up to two-thirds over
standalone GP personalisation.Comment: 43 pages, 11 figure
Will SDN be part of 5G?
For many, this is no longer a valid question and the case is considered
settled with SDN/NFV (Software Defined Networking/Network Function
Virtualization) providing the inevitable innovation enablers solving many
outstanding management issues regarding 5G. However, given the monumental task
of softwarization of radio access network (RAN) while 5G is just around the
corner and some companies have started unveiling their 5G equipment already,
the concern is very realistic that we may only see some point solutions
involving SDN technology instead of a fully SDN-enabled RAN. This survey paper
identifies all important obstacles in the way and looks at the state of the art
of the relevant solutions. This survey is different from the previous surveys
on SDN-based RAN as it focuses on the salient problems and discusses solutions
proposed within and outside SDN literature. Our main focus is on fronthaul,
backward compatibility, supposedly disruptive nature of SDN deployment,
business cases and monetization of SDN related upgrades, latency of general
purpose processors (GPP), and additional security vulnerabilities,
softwarization brings along to the RAN. We have also provided a summary of the
architectural developments in SDN-based RAN landscape as not all work can be
covered under the focused issues. This paper provides a comprehensive survey on
the state of the art of SDN-based RAN and clearly points out the gaps in the
technology.Comment: 33 pages, 10 figure
CULTURAL DIVERSITY AND HUMAN RESOURCE MANAGEMENT IN MULTINATIONAL COMPANIES
Sustainability tends to become in the new millennium the most important characteristic of economic and social development. The possibility to ensure economic development in the context of a reasonable use of raw materials, energy and natural resources in general and to decrease the impact of all human activities on the environment makes the essence of the sustainable development of these activities.sustainable development, globalization, natural resources, decentralization, environment, efficiency
Mobile Phone:The Past,The Present and The Future
Since the introduction of cellular analogue phone in 1985 (first generation mobile phone),
there has been a continuous improvement from the first generation to digital secondgeneration
to 2.5 generation and now the third-generation. The ground is also being
prepared for the fourth-generation mobile phone. Mobile technology has transformed our
lives in ways that might have seemed unimaginable some years ago and yet we are still
witnessing more transformations and many more are yet to come. This paper examines the
concept of cellular communication, the development of mobile phones, the features in the
past, the current trends and what to the future holds in general and specifically for Nigeria.
The cost implications of the various generations over the previous ones to the end users are

Standard Selection Modes in Dynamic, Complex Industries: Creating Hybrids between Market Selection and Negotiated Selection of Standards
Several sectors within Information and Communication Technology demonstrate a shift from purely market-based selection of standards or purely negotiated selection of standards to hybrid selection processes, where both market competition and negotiation play a role. Negotiated standard setting processes (such as those organised by the ITU) assure interoperability of technical components and services. Private firms, however, increasingly tend to undercut these collective actions. Their innovations jump-start new developments, but also create incompatibilities, lock-in effects, and pockets of market power. Internet telephony is an example, where firms, standard setting alliances, and political institutions create a hybrid market-based / negotiated standard setting environment. The paper explores the development of this hybrid networking environment. It posits propositions which are illustrated by means of case studies of the DVD and Internet telephony.industrial organization ;
From viability to sustainability: the contribution of the viable systems approach (VSA)
The current dynamics of business systems require new ways of conceiving the role of single entities. On this basis, a complex of interactions between the company and the reference context must be activated to guarantee survival dynamics. From these considerations re-emerge the ideas of Peccei (2013) and King (2013) that recognise in the systemic thought the foundations for a sustainable society. The present study derives from these considerations, and aims at contributing to the advancement of the knowledge necessary to overcome the challenges in the sustainability field. The methodological approach, albeit heuristic, can be traced back to the positive scientific and constructivist method. The results of the study showed the prevalence of qualitative and subjective
techniques, accompanied by the so-called inductive method, testifying to the intense interaction between the scholar and the object investigated. With regard to future research, it would be interesting to construct a flexible, scalable and extensible model to recover both a database and an ontology for
