Abstract

This paper draws attention to the value of a new generation of information servers as a tool for human communication. Section I introduces the notion that the Internet is heralding a new era in communications, where peoples of different age and background are able to communicate with each other without barriers of distance or time. Section 2 examines the client‐server architecture which, together with the advent of graphic user interfaces, made possible a new generation of distributed, platform‐independent information servers. Four of the new generation servers are discussed in the remaining sections, namely Archie, gopher, WAIS and the World Wide Web, as well as video‐conferencing with CU‐seeMe.

Abstract

The feasibility of publishing an electronic journal which will be accepted by the scientific community has always been hampered by factors such as a lack of standardisation of data transmission codes, limitations regarding the incorporation of graphics and photographs, as well as the absence of special columns, book reviews, letters to the editor, product reviews and advertisements. Standardised communication protocols such as TCP/IP have brought this dream one step closer to reality. The final step could be an electronic journal published through the World Wide Web (WWW), currently one of the frequently used Internet navigators. Three WWW specifications provide the ideal arena for electronic journal publishing: URL (uniform resource locator), HTTP (hypertext transfer protocol), and HTML (hypertext markup language). These specifications provide a standardised structure for storing, accessing and sending data, including multimedia (even sound and video) files. The possibilities of such a structure for electronic journal publishing are remarkable: full‐text retrieval could not only be by keyword but also by following hypertext links across articles — even to nodes in other computer systems. In this article the possibilities of publishing via the Web will be addressed and some hints for setting up and maintaining a multimedia scholarly journal will be provided.

Abstract

An introduction is given to some of the resources on the Internet that may be used in academic libraries in Europe. Particular reference is made to accessing other libraries' catalogues, document delivery services, shared information products and campus wide information systems. Several figures of screen outputs are included to provide the reader with an insight into the range of information available. The use of the Bulletin Board for Libraries (BUBL) as a starting point for finding out about resources on the Internet is suggested.

Abstract

Purpose

The purpose of this paper is to determine dependencies between a rotor-blade shape and a rotor performance as well as to search for optimal shapes of blades dedicated for helicopter main and tail rotors.

Design/methodology/approach

The research is conducted based on computational methodology, using the parametric-design approach. The developed parametric model takes into account several typical blade-shape parameters. The rotor aerodynamic characteristics are evaluated using the unsteady Reynolds-averaged Navier–Stokes solver. Flow effects caused by rotating blades are modelled based on both simplified approach and truly 3D simulations.

Findings

The computational studies have shown that the helicopter-rotor performance may be significantly improved even through relatively simple aerodynamic redesigning of its blades. The research results confirm high potential of the developed methodology of rotor-blade optimisation. Developed families of helicopter-rotor-blade airfoils are competitive compared to the best airfoils cited in literature. The finally designed rotors, compared to the baselines, for the same driving power, are characterised by 5 and 32% higher thrust, in case of main and tail rotor, respectively.

Practical implications

The developed and implemented methodology of parametric design and optimisation of helicopter-rotor blades may be used in future studies on performance improvement of rotorcraft rotors. Some of presented results concern the redesigning of main and tail rotors of existing helicopters. These results may be used directly in modernisation processes of these helicopters.

Originality/value

The presented study is original in relation to the developed methodology of optimisation of helicopter-rotor blades, families of modern helicopter airfoils and innovative solutions in rotor-blade-design area.

Abstract

Purpose

The purpose of this paper is to evaluate food fraud detection in the Czech food retail market based on the findings of the Czech Agricultural and Food Inspection Authority (CAFIA).

Design/methodology/approach

The outcomes of administrative proceedings from 2009 and 2013 were used. Data were collected from e-databases of the CAFIA and sorted by the current valid qualification for food fraud following Article 16, Regulation (EC) No. 178/2002 of the European Parliament and of the Council.

Findings

Food fraud was detected, almost to the same extent, in both selected years by laboratory testing as well as on the basis of “on the spot” controls in retail establishments. The meat products were a food group with the most fraudulent tendency in both selected years.

Originality/value

This paper contributes to the overview of food fraud and could help to detect ways of food deception for the competent authorities and consumers.

Abstract

Purpose

The purpose of this paper is to examine the extent to which HTTPS encryption and Google Analytics services have been implemented on academic library websites, and discuss the privacy implications of free services that introduce web tracking of users.

Design/methodology/approach

The home pages of 279 academic libraries were analyzed for the presence of HTTPS, Google Analytics services and privacy-protection features.

Findings

Results indicate that HTTPS implementation on library websites is not widespread, and many libraries continue to offer non-secured connections without an automatically enforced redirect to a secure connection. Furthermore, a large majority of library websites included in the study have implemented Google Analytics and/or Google Tag Manager, yet only very few connect securely to Google via HTTPS or have implemented Google Analytics IP anonymization.

Practical implications

Librarians are encouraged to increase awareness of this issue and take concerted and coherent action across five interrelated areas: implementing secure web protocols (HTTPS), user education, privacy policies, informed consent and risk/benefit analyses.

Originality/value

Third-party tracking of users is prevalent across the web, and yet few studies demonstrate its extent and consequences for academic library websites.

Abstract

Purpose

The term smartness has been discussed in the academia for many years; prior research has listed numerous advantages and encouraged business entities to implement smart technologies. However, stakeholders’ knowledge level, support intention and barriers to smart technology have been under investigated. Without the support of stakeholders, smart projects can hardly be implemented. This paper aims to explore the above-mentioned under investigated area and identify the gaps between academia and the hotel industry in Taiwan.

Design/methodology/approach

In-depth interviews were conducted with nine hotel stakeholders in Taiwan with investors, owners, managers, technology suppliers and information technology consultants. Three key areas were focused on: smart hotel definition, expectations from smart hotel and known barriers for implementing smart technologies.

Findings

The definition of smart hotel among all stakeholders was inconsistent. Stakeholders defined a smart hotel according to their role in the organization: revenue boost, service customization, operations effectiveness and in-room automation. However, the key functions of smart technologies, such as interconnectivity and interoperability with business partners’ application (e.g. online travel agencies) and linkage to external Big data for accurate revenue forecast, were not mentioned by the interviewees. In addition, social media monitoring, robots and artificial intelligence were not mentioned during the interview.

Originality/value

This study attempted to identify Taiwanese hotel stakeholders’ perspective on smart hotel and to compare the outcome with academic research. The result indicated that there is a big gap in the definition of “smart hotel” among stakeholders and academia and reflected several barriers that prohibit hotel owners and investors in implementing smart systems.

Abstract

Purpose

The purpose of this paper is to introduce two new (3 + 1)-dimensional Boiti–Leon–Manna–Pempinelli (BLMP) equations, the first with constant coefficients and the other with time-dependent coefficients. The author obtains multiple soliton solutions and multiple complex soliton solutions for the two developed models.

Design/methodology/approach

The newly developed models with constant coefficients and with time-dependent coefficients have been handled by using the simplified Hirota’s method. The author also uses the complex Hirota’s criteria for deriving multiple complex soliton solutions.

Findings

The two developed BLMP models exhibit complete integrability for any constant coefficient and any analytic time-dependent coefficients by investigating the compatibility conditions for each developed model.

Research limitations/implications

The paper presents an efficient algorithm for handling integrable equations with constant and analytic time-dependent coefficients.

Practical implications

The paper presents two new integrable equations with a variety of coefficients. The author showed that integrable equations with constant and time-dependent coefficients give real and complex soliton solutions.

Social implications

The paper presents useful algorithms for finding and studying integrable equations with constant and time-dependent coefficients.

Originality/value

The paper presents an original work with a variety of useful findings.
