This paper aims to suggest a new revolutionary method and installation for flight on Earth and into outer space.

Methods of electromagnetic physics are used for research and the theory of levitation vehicles is developed and its possibilities researched.

It was found that levitation devices and electricity storage make a jump in aviation, space, storage and transfer energy and many branches of industry.

Many projects were calculated using different versions of the offered AB engine: a small device for levitation‐flight of a human (including flight from Earth to outer space), fly VTOL car (track), big VTOL aircraft, suspended low‐altitude stationary satellite, powerful Space Shuttle‐like booster for travel to the Moon and Mars without spending energy (spent energy is replenished in braking when the ship returns from another planet to its point of origin), using AB‐devices in military, in sea‐going ships (submarines), in energy industry (for example, as small storage of electric energy) and so on. The vehicles equipped with AB propulsion can take flight for days and cover distances of 10,000s of kilometers at hypersonic or extra‐atmosphere space speeds.

The paper promises a new revolutionary method of flight on Earth and into outer space.

The first videodisc was demonstrated in 1927. A brief history of the videodisc is presented, describing the three major current manifestations of this storage medium—read‐only, write‐once, and erasable. Read‐only became an important information delivery format in 1985. During 1986, write‐once will begin to have impact on libraries and information centers. The current status of this technology, the major corporations involved in the field, and the potential uses for various types of storage media are described. A sidebar discusses Geac's use of optical media.

The costs of alternative methods of storing data have changed significantly as electronic systems have evolved. Moreover, we expect the average level of costs to continue falling over the next decade as technical change continues. Electronic systems are becoming closer substitutes for traditional ways of storing information in libraries. This issue's column examines the storage capacity of a wide array of representative storage devices in terms of the number of billions of characters or bytes of information—that is, gigabytes of storage—and each system's costs. The cost per gigabyte (GB) of storage varies by several orders of magnitude in ways that have important implications for the evolution of libraries over the next decade.

With the rapid deployment of internet of things (IoT) technologies, it has been essential to address the security and privacy issues through maintaining transparency in data practices. The prior research focused on identifying people's privacy preferences in different contexts of IoT usage and their mental models of security threats. However, there is a dearth in existing literature to understand the mismatch between user's perceptions and the actual data practices of IoT devices. Such mismatches could lead users unknowingly sharing their private information, exposing themselves to unanticipated privacy risks. The paper aims to identify these mismatched privacy perceptions in this work.

The authors conducted a lab study with 42 participants, where they compared participants’ perceptions with the data practices stated in the privacy policy of 28 IoT devices from different categories, including health and exercise, entertainment, smart homes, toys and games and pets.

The authors identified the mismatched privacy perceptions of users in terms of data collection, sharing, protection and storage period. The findings revealed the mismatches between user's perceptions and the data practices of IoT devices for various types of information, including personal, contact, financial, heath, location, media, connected device, online social media and IoT device usage.

The findings from this study lead to the recommendations on designing simplified privacy notice by highlighting the unexpected data practices, which in turn, would contribute to the secure and privacy-preserving use of IoT devices.

This paper aims to forecast the future of data storage technologies, using the case of two major technologies driving the data storage world; hard disk drive (HDD) or conventional longitudinal recording and flash memory.

Four principal tools of forecasting technology are applied to present the coming future of data storage technologies. These tools consist of bibliometric trend analysis, patent trend analysis, technology cycle time (TCT), and growth curve. Numbers of publications each year and cumulative patents are used to analyze the future of these competitive technologies. The median age of the patents is applied to find the technology lifecycle of both technologies. Finally, areal density of HDD is plotted on the growth curve to forecast the saturation point of researching on conventional longitudinal recording.

The results produced from utilizing these tools indicate that these two technologies are continuously under development. It is found that the growth of improving areal density of conventional recording will be nearing zero by year 2013 and the maximum growth rate of development was in year 2006.

The forecasting is based on principal technologies of conventional longitudinal recording of HDD. Also, NOR and NAND are considered as two main technologies dominating flash memory. Other emerging data storage technologies such as holographic data storage, phase‐change memory (PCM) are not included in this paper. Likewise, the growth curve of flash memory is not analyzed as part of this paper.

This paper forecasts the future of data storage technologies. Integration of scientific indicators and growth curves is demonstrating a powerful tool for forecasting technology futures.

The purpose of this paper is to introduce Commercial Mobile Video Service Trial (TOEST) of Korea Telecom (KT), relaying experience related to the implementation of mobile video service for portable devices to libraries and information management organizations that are interested in this service.

Research data used were collected from internal materials such as unpublished project reports, RFI, RFP, etc. written throughout the process of implementing projects. The information also draws on the author's experience and involvement in TOEST trial between 2005 and 2007.

From the technical perspective, it was confirmed that technical advancements and environments that enable the implementation of mobile video service for portable devices have been fully established. The technical areas that need to be further improved are the advancements of battery capacity, low‐power consumption technology, and functional improvement of the I/O slot in portable devices.

TOEST provides only download type service for portable devices such as PDAs and PMPs. Streaming type service for mobile phones has been performed only for the purpose of internal tests.

For information management organizations and libraries, mobile video service for portable devices is cutting‐edge technical service that can provide new customer value to users. Also, it is possible to apply profit models from the commercial point of view.

The paper introduces various technical and environmental elements as specifically as possible, including practical things that we have experienced during the course of implementing mobile video service systems for portable devices. Experience in TOEST development would be helpful to information management organizations and libraries planning to provide mobile video service for portable devices.

Fog computing is a new field of research and has emerged as a complement to the cloud which can mitigate the problems inherent to the cloud computing model such as unreliable latency, bandwidth constraints, security and mobility. This paper aims to provide detailed survey in the field of fog computing covering the current state-of-the-art in fog computing.

Cloud was developed for IT and not for Internet of Things (IoT); as a result, cloud is unable to meet the computing, storage, control and networking demands of the IoT applications. Fog is a companion for the cloud and aims to extend the cloud capabilities to the edge of the network.

Lack of survey papers in the area of fog computing was an important motivational factor for writing this paper. This paper highlights the capabilities of the fog computing and where it fits in between IoT and cloud. This paper has also presented architecture of the fog computing model and its characteristics. Finally, the challenges in the field of fog computing have been discussed in detail which need to be overcome to realize its full potential.

This paper presents the current state-of-the-art in fog computing. Lack of such papers increases the importance of this paper. It also includes challenges and opportunities in the fog computing and various possible solutions to overcome those challenges.

The key purpose of this study is to explore digital information literacy (DIL) possessed by South Valley University (SVU) library and information professionals. It also tries to identify the various types of DIL and find constraints affecting the related skills and competencies of those professionals.

A quantitative research methodology was adopted in the form of a survey, which was undertaken from February to March 2016. As stated by Kerlinger (1986), the survey research is a useful instrument for educational fact-finding, and a means by which much information can be acquired from the study’s population. The survey instrument was a self-administrated questionnaire, which was adopted for data collection. A pilot questionnaire was first sent to a small random sample of the respondents, with feedback being used to fine-tune the final questionnaire. The targeted population of this study included library and information professionals (n = 127) belonging to SVU libraries that spread over three provinces/campuses: the Qena campus (number of libraries = 22), the Luxor campus (n = 3) and the Hurghada campus (n = 2). The library and information professionals are described to be librarians, library assistants and library directors. Of 127 questionnaires, 101 (79.5%) responses were received. To collect data, the study used a questionnaire, which has six sections reflecting the research objectives of the study.

The findings showed that over two-thirds of SVU library and information professionals are males, and almost one-third are females. Majority respondents are aged between 26 and 40 years, and most possessed bachelor’s degrees, of which nearly two-thirds held library science degrees. Regarding the respondents’ professional profile, the study also showed that majority were librarians, followed by library assistants and library managers, and nearly half had 10 years of experience, followed by those who have work experience of 6-7 years. This study showed that there is a significant relationship between some of the respondents’ demographic characteristics (age and education) and their DIL. The respondents’ gender had no effect on their DIL. The study also showed that there is a significant relationship between all the respondents’ professional characteristics, particularly their discipline, followed by job title, work experience and DIL. Regarding the level of respondents’ knowledge of the types of computers, many showed that their knowledge of using mobile devices, followed by PCs, workstations, portable media players/digital audio player and personal digital assistant was, at the least, high. The respondents’ knowledge of other types ranged between moderate to non-proficient. A large number of the respondents showed that their proficiency in using output devices, followed by input devices, processing devices, storage devices and communication devices was also, at the least, high. While the largest number of the respondents showed that their proficiency in using application software was, at least, high, the largest number of them showed that their proficiency in using system software was moderate. Regarding the respondents’ knowledge-based competencies, as well as skills-based competencies, especially when these competencies related to the integration of ICTs into the library work, this study showed that such kind of competencies possessed by SVU library and information professionals ranged between competent and somewhat competent. Regarding the challenges affecting the respondents’ acquiring skills and related competencies, the study revealed that the lack of funds, training, physical facilities, connection to the internet, subscribing to e-databases, lack of time as well as challenges related to SVU library system regulations, were significant to them. Other challenges such as the lack of incorporating and exploiting the new technologies and products into library integrated systems educators’ services, as well as challenges related to psychological barriers, lack of current curricula in the area of ICTs and a shortage of experienced LIS counselors, were also significant to them. This study reached conclusions that the SVU library and information professionals should be qualified and get adapted to ICTs and related competencies. They need to be provided with sufficient training to update their knowledge regarding the use and integration of technology in their library work.

This study investigates DIL among library and information professionals at SVU, an Egyptian university. Any findings and conclusions resulted from this study are limited in scope to only the library professionals of this university. Such a topic has limited previous research. The size and homogeneity of the sample limit the generalizability of this study.

The study aims to investigate DIL acquired by SVU library and information professionals. The potential results of this study would be useful for library schools, library associations and other pertinent authorities for the planning of training programs and courses. The findings may also be helpful for library educators to develop curricula that meet the needs of library and information professionals.

This study is one of the few studies conducted on this topic in Egypt. The literature on the topic of this research revealed that extensive research has been undertaken on DIL in higher education in developed countries, but very limited research has been conducted on this topic in Egypt and similar developing countries, particularly among academic library and information professionals. No definition for the concept of DIL has yet been produced, and many Egyptian academic institutions define this concept based on their own needs depending on existing models.
