Signal Coverage

Recent advances in IT have offered people the opportunity to have powerful ultramobile devices in their pockets incorporating a plethora of capabilities which, in most cases, require Internet connectivity. This constant need for Internet access though, especially when a wireless hotspot is unavailable requires connection via network data. The fixed cellular data packages offered by carriers usually do not come for free and to a large extend cannot be adapted to the dynamic needs of users who sometimes need more than they own, while in other cases under-use their network data.  This issue, in combination with the fact that signal quality in many areas is not even fair for one or more carriers has led to the development of a novel android application that aims at allowing users in general and tourists to “foresee” bad signal coverage at places of their interest, as well as to share their cellular data via mobile tethering.

Modeling Data

Recent advances in latent space and related random effects models hold much promise for representing network data. The inherent dependency between ties in a network makes modeling data of this type difficult. In this article we consider a recently developed latent space model that is particularly appropriate for the visualization of networks. We suggest a new estimator of the latent positions and perform two network analyses, comparing four alternative estimators. We demonstrate a method of checking the validity of the positional estimates. These estimators are implemented via a package in the freeware statistical language R. The package allows researchers to efficiently fit the latent space model to data and to visualize the results.

Library catalog is a documentation or list of all library collections. Unfortunately, there is a problem identified in the process of searching a book inside library catalog in Universitas Multimedia Nusantara’s library information system regarding the relevant result based on user query input. This research aims to design and build a library catalog application on Android platform in order to increase the relvancy of searching result in a database using calculated Rocchio Relevance Feedback method along with user experience measurement. User experience analysis result presented a good respond with 91.18% score based by all factor and relevance value present 71.43% precision, 100% recall, and 83.33% F-Measure. Differences of relevant results between the Senayan Library Information system (SLiMS) and the new Android application ranged at 36.11%. Therefore, this Android application proved to give relevant result based on relevance rank. Index Terms—Rocchio, Relevance, Feedback, Pencarian, Buku, Aplikasi, Android, Perpustakaan.

Access Service

The measuring of rendered services in any industry, especially in libraries, remains a critical tool to assess the satisfaction level of clients as well as the quality of the services. This article reports on a study that was undertaken to measure the quality of internet access service to South African public libraries by using the service quality model. The paper was guided by these objectives to identify the service quality models applicable to public libraries’ internet access; to determine how the quality of internet access service fits within the South African broadband policy; and to apply service quality dimensions to public libraries’ internet access. The study employed a quantitative approach and survey design in which a questionnaire was used to collect data from 322 heads of public libraries in South Africa. The stratified sampling method was used to obtain a proportional representation of public libraries. It emerged that most respondents regarded their internet service providers (ISPs) as incapable of solving their technical problems. It was further found that in most cases ISPs applied the internet access policies inconsistently to public libraries they served. The study recommended, among others, that internet connectivity to public libraries be centralised and that a competent provider be appointed to manage this service.

This chapter reports user experience findings from two field trials, where Mobile Internet access was supported through Near Field Communication (NFC)-based tag infrastructure, The first field trial was done in public urban environment with the infrastructure of 2650 tags and 248 users, and the other field trial dealt with mobile learning with the infrastructure of 11 tags and 220 users. The authors results show that touch-based interaction can provide enhancement to the Mobile Internet user experience. Touch-based access builds a semantic bridge between the physical context of use and the Mobile Internet experience, the user experience converges seamlessly into one where both the physical and digital worlds play a role. The authors report and analyze the subjective experiences of the end users collected during the field trials. As a result, they summarize recommendations for interface and content design.

The Internet Of Things

As satellite communications provide ubiquitous coverage, they play a key role in providing Internet connectivity in remote or marginalized areas, so as to enable the vision of a truly global connectivity of the Internet of Things (IoT). However, these areas often lack reliable electricity supply. Thus, this paper proposes a satellite internet access point powered by solar energy, so that a stable Internet connection can be provided. The access point provides Wi-Fi coverage so that sensors, IoT, and devices can connect to the access point using the Wi-Fi, a common wireless technology. Our design took some cost-saving measures to make it affordable and selected the components that require minimal maintenance operations. The satellite access point costs about USD $500, and can provide four days of Internet connectivity without solar energy.

Abstract Aiming at the problems of the traditional centralized data sharing platform, such as poor data privacy protection ability, insufficient scalability of the system and poor interaction ability, this paper proposes a distributed data sharing system architecture based on the Internet of Things and blockchain technology. In this system, the distributed consensus mechanism of blockchain and the distributed storage technology are employed to manage the access and storage of Internet of Things data in a secure manner. Up to the physical topology of the network, a hierarchical blockchain network architecture is proposed for local network data storage and global network data sharing, which reduces networking complexity and improves the scalability of the system. In addition, smart contract and distributed machine learning are adopted to design automatic processing functions for different types of data (public or private) and supervise the data sharing process, improving both the security and interactive ability of the system.

Higher education students use mobile phones, equipped for Internet access. Mobile technologies can offer effective, satisfying and accessible m-learning experiences. A contribution has been made to knowledge on evaluating m-learning environments and to mobile human-computer interaction (MHCI), with the innovative synthesis of the MUUX-E Framework, which fills a gap in the domain of m-learning. MUUX-E is a single comprehensive, multi-faceted instrument for evaluating m-learning environments, emphasising usability and user experience in mobile educational contexts. It was developed by extensive literature studies on each aspect, and has five categories, 31 criteria and numerous sub-criteria. Using a design-based research paradigm, MUUX-E was applied iteratively to evaluate and enhance successive versions of m-LR, a mobile application created for a Software Engineering module. Participants were students and expert evaluators. MUUX-E served well to identify problems and strengths. The students were more positive than the experts regarding the benefits of m-LR, yet insightfully reported more system problems.
