The following chapter focuses on the problem of the proper definition of non-functional properties and methods that may be applied in order to estimate their values. First of all, a reader is familiarized with the concept of non-functional properties and different views on the quality of Web services. Then, selected approaches to obtain values of nonfunctional properties are presented. The focus of attention is Web services profiling that seems to be one of the most promising methods to perform this task. The framework presented in this chapter was implemented and tested within the EU Adaptive Services Grid project.

Selection Framework

With the rapid development of Web services technology, more and more Web services emerged in the network. Service consumer attached importance to the functional properties of services, also more and more emphasis on non-functional properties, namely Quality of Service. The Ultimate goal is meet consumer the demand of QoS. Therefore, service providers paid more and more attention to quality of services to meets the needs of users. This takes into account the options to meet the functional requirements and the QoS requirements, and designed a Web service selection framework. At the same time, QoS attributes can be added or deleted the number, so it is an extendible framework. The results show that the framework could select the appropriate service for users.

The presented approach draws on two main software techniques: Model-Driven Architecture, and aspect-oriented programming. The method involves modeling of the Quality of Service and Extra-functional properties in a platform-independent fashion. Then applying model transformation, the platform-independent models are transformed into platform-specific models, and finally into code. The code for Quality of Service and Extra-functional properties are integrated into the system relying on aspect-oriented techniques in a decoupled manner. The presented approach is evaluated with the help of a case study to establish that the approach results in increasing the system’s modularity and thus reducing implementation and maintenance costs.

Abstract. A detailed analysis of the measurement procedures recommended by the International Telecommunication Union (ITU) shows that – with proper definition of audio quality – the FM broadcasting system can provide an audio signal-to-noise ratio of no better than 40 dB, when the interference in the neighboring channels exhausts the limits established by the internationally agreed protection ratios. Thus any attempt to relax the protection, be it motivated by the desire to implement additional FM or new digital services in the FM band, would inevitably degrade reception quality of existing services to levels hardly acceptable by broadcast listeners.

This chapter presents the definition of relevant terminology and a conceptual model of the basic terms. The chapter starts with the presentation of research in the area of dependability. Based on this, Web service concepts related to the dependability are introduced. The presentation leads into a statement identifying individual quality-of-service (QoS) characteristics for forming dependable Web services. Then, the chapter discusses the current status quo in the area of QoS-aware Web services. This part is divided into three subparts: description, management, and monitoring. This also identifies ongoing efforts as well as efforts that do not show present activity. By this discussion, this chapter puts research about dependability in relation with ongoing QoS-related efforts in the Web services domain. Thus it identifies how these efforts can be combined in order to form a dependable Web services platform.

Discussion on the EU definitions of ‘waste’, as well as ‘recovery’ and ‘disposal’ of waste have been, to paraphrase a standing expression, plentiful and hard on each other’s heels. Ever since the 1991 amendments to the 1975 framework directive, attempts have been made to disprove the usefulness of the definition of waste, and to question the lack of proper definition of the concepts of recovery and disposal. In order to assess the recently issued Commission Proposal for a (renewed) directive on waste, this contribution reviews first of all, succinctly, the nature and limitations of the ‘old’ (existing) definitions, subsequently it reviews the proposed changes.

Abstract The aim of this paper is to assess if and how a concept of accounting quality differs from perspectives of various types of organisations affected by the accounting harmonisation process. Accounting harmonisation is commonly associated with worldwide adoption of IFRS by public interest companies. However, in the EU this process is much broader and also involves efforts to harmonise accounting standards for non-listed companies and public sector organisations. Analysis of the previous scientific research revealed that accounting quality was commonly assessed from IFRS users’ perspective and approximated with the quality of financial statements. However, based on the interviews with experts of Lithuanian accounting market, the concept of accounting quality for small and medium companies and public sector institutions is ambiguous and still needs to be clarified. Definition of accounting quality only as the quality financial statements is too narrow as financial disclosure is not that important for such companies. For non-listed companies and public sector organisations, other aspects and factors, such as qualification of accountants, supervision of accounting and reporting, overall and managers’ perspective on importance of accounting, have more importance while defining accounting quality.

Investigations on the baking quality of winter wheat, which is the most important bread cereal in Hungary, have been in the focus of attention for a long time. it is useful to study the theoretical and practical aspects of European quality testing systems, because different European methods are generally mutually accepted in the EU. Many recognised testing methods have been developed in Hungary over the last hundred years. In the present experiments studies were made on the effect of the year, variety and mineral fertilization and their interactions on alveographic parameters. in the years examined, the main factor which determined the alveographic values was found to be the variety. fertilization had a significant effect on the examined parameters, but in most cases no regular trends were observed. The year only modified wheat quality in interactions.

Smart Villages is an approach to rural development which has been under discussion in the EU as one of the subthemes that the ENRD is working on. For this reason, the Thematic Group (TG) on Smart Villages was launched in 2017. Since then it has been contributing to the definition of smart villages, discussing the changes in rural development policy and opportunities for providing support for smart villages, exchanging experience and best practices in smart rural development, and serving as a forum for dialogue between various rural stakeholders. This paper outlines the discussion held during the selected meetings of the TG and briefly indicates the academic background of the approach discussed. Its aim was to present Smart Villages in terms of EU policy. Hence, the paper presents the genesis of the EU debate, highlights some of the dilemmas of the definition of smart villages, indicates the role of the territorial governments and the EU in creating the conditions for implementing the approach, and shows the selected examples of smart rural development. Smart Villages is an alternative way of thinking about the quality of rural life, and it seems to respond to the way the EU policy is evolving. However, it calls for better tailored tools and instruments, which applies both to EU policies and national/regional sources. It also calls for regional and local governments to play their role in the process.

Until now, the properties of honey have been defined based exclusively on the content of plant components in the nectar of given plant. We showed that apalbumin1, the major royal jelly (RJ) protein, is an authentic and regular component of honey. Apalbumin1 and other RJ proteins and peptides are responsible for the immunostimulatory properties and antibiotic activity of honey. For the quantification of apalbumin1, an enzyme-linked immunosorbent assay (ELISA) was developed using polyclonal anti-apalbumin1 antibody. The method is suitable for honey authenticity determination; moreover it is useful for detection of the honey, honeybee pollen and RJ in products of medicine, pharmacy, cosmetics, and food industry, where presences of these honeybee products are declared. Results from the analysis for presence and amount of apalbumin1 in honeys will be used for high-throughput screening of honey samples over the world. On the basis of our experiments which show that royal jelly proteins are regular and physiologically active components of honey we propose to change the definition of honey (according to the EU Honey Directive 2001/110/EC) as follows: Honey is a natural sweet substance produced by honey bees from nectar of plants or from secretions of plants, or excretions of plant sucking insects, which honey bees collect, transform by combining with major royal jelly proteins and other specific substances of their own, deposit, dehydrate, store and leave in the honey comb to ripen and mature.
