To describe the architecture of iPOS (short for iPAQ positioning system), a novel fault‐tolerant and adaptive self‐positioning system with quality‐of‐service (QoS) guarantees for resource‐limited mobile devices.

The iPOS architecture is based on a novel sensor modelling technique in combination with a probabilistic data‐fusion engine, which is capable of efficiently combining the location information obtained from an arbitrary number of heterogeneous location sensors. As a proof of concept, the paper present a prototypical implementation for handheld devices, which was evaluated by means of practical experiments.

A major advantage of the iPOS positioning system is its extensibility and flexibility, which is achieved by means of an open plugin architecture and the support of global positioning coordinates according to the WGS‐84 standard. The iPOS system scales very well with respect to the number of sensor plugins that can be operated in parallel. The main limiting factor for the number of supported active plugins is the amount of available system resources on the MoD. With regard to recognition, the experimental results indicate a good accuracy of the fusion‐based positioning system in comparison to the accuracy of the individual sensing technologies. Thanks to the explicit modelling of reliable sensor events, the iPOS system is capable of providing QoS guarantees to applications with regard to the achieved positioning accuracy.

During the experiments, the author recognized time synchronisation as an important challenge that should be addressed as part of future work.

The system enables resource‐restricted mobile devices and computerised objects to exploit computing resources found in their immediate physical vicinity (locality).

The paper presents a novel lightweight sensor‐fusion architecture for fault‐tolerant and adaptive self‐positioning that performs well on resource‐limited mobile devices. A special feature of the developed data‐fusion architecture is the application of a novel event modelling technique that enables the positioning system to give QoS guarantees under certain conditions.

Questioning gender is about taking an active, critical role in the technological design of our daily behaviour. It is a deconstruction of the oppositions that exist in the discourses of Ambient Intelligence designers, the ICT industry and computer scientists. What underlies the assumption that Ambient Intelligence will, by disappearing into our environment, bring humans both an easy and entertaining life? The gender perspective can uncover power relations within the promotion and realisation of Ambient Intelligence that satisfy an obvious wish for a technological heaven. The deconstruction of the promise of progress and a better life reveals what is overvalued, what is undervalued and what is ignored. This paper is a deconstruction of the view, currently prevalent in the discourses of Ambient Intelligence; a view of humans and the way they live. A view that will influence the way women and men will be allowed to construct their lives.

Building on neo-institutionalism models of the transfer of human resource management (HRM) practices within multinational companies, this paper aims to analyze the transfer of skill formation concepts using the cases of two automotive OEMs in Slovakia. The purpose of the paper is twofold. First, it aims to explain the differences between the two multinationals. Second, it builds on the empirical analysis to reconsider the neo-institutionalist theoretical framework.

The paper is based on two qualitative case studies of automotive multinationals in Slovakia. The home country locations of both companies represent different approaches to skill formation: systematic vocational education for blue-collar workers is regarded as crucial at the German manufacturer, while the Korean company relies mainly on on-the-job-training and puts much less emphasis on skilled blue-collar work.

The paper shows that the differences between the companies are related to different understandings of technology/automation. It argues that the increasing automation and the decentralization of responsibilities for the product-launch processes supported the transfer of German skill formation concepts to the plant in Slovakia, while the Korean manufacturer’s specific engineering-led automation concept and centralization of product launch responsibilities in its Korean headquarters reduced the need to invest in skill formation for blue collars abroad. The paper concludes that theories of the transfer of HRM practices within multinationals must include technological factors and must also develop more specific concepts of the centralization of multinationals.

The paper is to the knowledge the first to include technology as a core variable into the neo-institutionalist theory in the field of international business and HRM. While the relationship between technology and organization has gained huge prominence in the recent discussions about digitalization, it has been so far neglected by scholars of international business.

There have been several developments during the past year that will aid biologists in their constant battle to keep up with the scientific and technical literature. The Institute for Scientific Information (ISI) has introduced three new online services that are designed for current awareness and retrospective searches: ISI/CompuMath — access to pure and applied math literature; ISI/ISTP&B — index to scientific proceedings and books; and ISI/BIOMED — research front specialties in biomedicine.

Stuart Soloway, previously managing director of Shoppers Paradise, has left the food trade and become retail operations director with Burton Retail, part of the Burton Group. In his new post, in conjunction with two merchandise directors, he is responsible for 350 Burton stores.

This article aims to examine empirically the relationship between budget periodicity and expenditure volatility in state governments. Using a large panel dataset for fifty states over the years 1960-2012, after controlling for institutional, economic, and political factors, we find general expenditure of biennial states has been significantly less volatile than that of annual states. The finding suggests that a choice between annual and biennial budget period can emerge as a feasible and effective countercyclical strategy to overcome fiscal difficulties in the short run and promote fiscal stability in the long run.

Remarks on the parallel in the basis of the riches of the aristocracy and plutocracy. Illustrates the argument from the history of the development of the cotton textile industry, the underpinnings for its growth being the inventions prior to and during the eighteenth century. Exemplifies the part of inventions as the begetter of plutocratic wealth. Sir Richard Arkwright, notably, was its salacious issue.

The utilization of oilseeds in food formulations is prevalent due to their health benefits and nutritional value. These protein-rich oilseeds serve as an affordable and essential source of nutrients and bioactive compounds, fulfilling human protein requirements. As such, this study sought to investigate the impact of partially replacing wheat flour with oilseeds in different proportions on the nutritional and quality characteristics of biscuits.

Oilseeds, including terebinth, sesame and flaxseed, were partially substituted with wheat flour in amounts of 0, 5, 10, 15, 20 and 25%. The effects of this substitution on the storage stability, nutritional content and physical properties of the resulting biscuits were examined.

The L* (from 69.75 to 54.06) and b* (from 28.59 to 21.60) color values of biscuits decreased with the supplement of oilseeds. The oilseeds addition increased the protein, fat, energy, and ash values of biscuits. At the highest level of added terebinth, sesame and flaxseed, respectively, the amounts measured were 5984.62 mgGAE/kg, 1553.85 mgGAE/kg and 2169.23 mgGAE/kg, which were higher than the control biscuits (715.39 mgGAE/kg). The incorporation of oilseeds resulted in a substantial decrease in pH and peroxide values, while the moisture content was increased throughout the 6-month storage period. The use of terebinth in biscuits led to better oxidative stability than sesame and flaxseed-containing samples. The biscuit samples with terebinth had a longer induction time. The lowest induction time of biscuits with 25% flaxseed was chosen, approximately 3.5 h.

Oilseed flours, which are rich in lipids, have been shown to enhance the quality of biscuits. However, further studies could aim to reduce the amount of shortening used to improve their quality even further. Reducing the shortening could keep the lipid content at an acceptable amount, especially considering consumers' current expectations for low-fat foods.

Plant-based bioactive are generally known as secondary metabolites and have promising therapeutic attributes, especially antioxidative properties.

Thanks to this composition, some of these seeds have proven effective in controlling and preventing metabolic diseases (hypertension, hypercholesterolemia, diabetes, coronary heart disease and several types of cancer) as well as providing interesting properties to foods.

As result, oilseeds can be successfully used as functional and sustainable food ingredients to improve the functional, nutritional and storage stability of biscuits.
