This study is motivated by the vibrations that plague coating processes used in the manufacturing of coated sheet metal. These vibrations arise from time-dependent tension fluctuations within the sheet metal plate as well as from the eccentricity of the rollers used to transport the plate. The time-dependent tension is observed to be rather broad-band and creates multi-frequency parametric excitation. By contrast, the roller eccentricity is largely single-frequency (synchronized with the roller speed) and creates single-frequency external excitation. The plate and excitation sources are studied herein using a single-degree-of-freedom model with a cubic nonlinearity, subject to combined parametric and external excitation. In our study, we investigate the resonances that arise from the synergistic effects of multi-frequency parametric excitation and single-frequency external excitation. For the simpler case of single-frequency parametric excitation, we observe both sum and difference combination resonances in addition to principal parametric resonance. For the case of multi-frequency parametric excitation, we observe a frequency shift for the parametric resonance that derives from the cubic nonlinearity and external excitation. Moreover, the phase relationships of the external and each parametric excitation source have a significant effect on the resulting response amplitude. We use these analyses to explain the resonance mechanisms observed in experiments conducted on an example sheet metal coating process.

The study is intended to explore COVID-19 information seeking and utilization among women in Warri Metropolis, Delta State, Nigeria. Descriptive survey research design was adopted using a self-constructed questionnaire to collect data. Data were analyzed using simple percentages. Findings revealed that a majority of the women need information on COVID-19 preventive measures, followed by causes of the pandemic; Internet is the source of COVID-19 information used by the highest number of respondents, followed by television and social media; a majority of them consider the authority of the source of the information on coronavirus followed by usefulness of the information; a majority access COVID-19 information to enable them identify symptoms of the disease followed by protection against COVID-19 infection while concern for reliability of much of the available information on the pandemic was a major barrier to their utilization of COVID-19 information. It is recommended that effort should be made by government to get mobile network operators to reduce network tariff.

The globally observed recession of mobile services market has pushed mobile network operators into looking for opportunities to provide value added services on top of their high cost infrastructures. Recent advances in mobile positioning technologies enable services that make use of the mobile user location information, offering intuitive, attractive applications to the potential customer. Mobile tourism services are among the primary options to be considered by service providers for this new market. This chapter presents the key concepts, capabilities, and considerations of infrastructures and applications targeted to the mobile tourist, covering data and content delivery, positioning, systems’ interactions, platforms, protocols, security, and privacy as well as business modelling aspects.

Mobile Network Operators

The use of mobile telecommunications devices for commercial transactions, coined mobile (m-) commerce, has been an emerging trend since the late 1990s. As the phenomenal growth of the Internet and mobile devices has continued unabated, the inevitable convergence of these two streams of technologies has occurred, promising a plethora of mobile data services to the handset user. Although these services have been considerably hyped in the media, and adoption has been somewhat patchy and limited, it does signal the emergence of a range of innovative value added services. With further developments in technology and markets, further services will appear, bringing new revenue streams. One potential area of m-commerce development is in location-based services (LBS). LBS are heralded as the next major class of value added services that mobile network operators can offer their customers. Using a range of network- and handset-based positioning techniques, operators will be able to offer entirely new services and improvements on current ones. Popular examples cited include emergency caller location, people or asset tracking, navigation, location-based information, or geographically sensitive billing. The purpose of this chapter is to examine the technologies, applications and strategic issues associated with the commercialisation of LBS. The chapter concludes with some predictions on the role of LBS in m-commerce.
