Pervasive computing at tableside : a wireless web-based ordering system

Purpose &ndash; The purpose of this paper is to introduce a wireless web-based ordering system called iMenu in the restaurant industry. Design/methodology/approach &ndash; By using wireless devices such as personal digital assistants and WebPads, this system realizes the paradigm of pervasive computing at tableside. Detailed system requirements, design, implementation and evaluation of iMenu are presented.Findings &ndash; The evaluation of iMenu shows it explicitly increases productivity of restaurant staff. It also has other desirable features such as integration, interoperation and scalability. Compared to traditional restaurant ordering process, by using this system customers get faster and better services, restaurant staff cooperate more efficiently with less working mistakes, and enterprise owners thus receive more business profits. Originality/value &ndash; While many researchers have explored using wireless web-based information systems in different industries, this paper presents a system that employs wireless multi-tiered web-based architecture to build pervasive computing systems. Instead of discussing theoretical issues on pervasive computing, we focus on practical issues of developing a real system, such as choosing of web-based architecture, design of input methods in small screens, and response time in wireless web-based systems.<br /

Simulation of undular bores evolution with damping

Propagation of undular bores with damping is considered in the framework of perturbed extended Korteweg-de Vries (peKdV) equation. Two types of damping terms for the peKdV equation, namely linear and Chezy frictional terms, which describe the turbulent boundary layers in the fluid flow are considered. Solving the peKdV equation numerically using the method of lines shows that under the influence of damping, the lead-ing solitary wave of the undular bores will split from the nonlinear wavetrain, propagates and behaves like an isolated solitary wave. The amplitude of the leading wave will remain the same for some times before it starts to decay again at a larger time. In general the amplitude of the leading wave and the mean level across the undular bore decreases due to the effect of damping

Opportunities For Funding Innovation

equity, business angels and the NewConnect market, and describes the possibilities of using them. The article stresses that firms seeking capital to grow through innovation can use a wide range of financing options as long as their projects are underpinned by solid documentation, have a specified time horizon, and are attractive for investdors.W artykule zaprezentowano pogląd, że konkurencyjność firmy należy upatrywać przede wszystkim w zdolności do bycia innowacyjnym. Wskazano na stymulatory aktywności firm i efekty z tytułu realizacji innowacji. Przede wszystkim zwrócono uwagę na źródła i formy pozyskiwania kapitału na ich urzeczywistnienie. Szczególną uwagę poświęcono leasingowi, venture capital, private equity, aniołom biznesu i NewConnect. Podkreślono, że istnieje szeroka paleta tych ofert dla firm potrzebujących kapitału na rozwój poprzez innowacje. Jednakże pod warunkiem, że projekty te będą dobrze udokumentowane, określony będzie horyzont czasowy ich wykonalności i będą stanowiły atrakcyjne wyzwanie dla inwestorów

Concept of comprehensive enterprises business model in global economic environment

The effective functioning of a modern enterprise necessitates the awareness of the owners and managers of its strategic orientations, the state of the internal and external environment, its competitive advantages, entrepreneurial potential and development prospects. A well-built business model of the enterprise helps to face these urgent and permanent challenges. However, the formation of a real business model of the enterprise necessitates mastering of theoretical and methodological bases and implementation of long-term practical measures in the field of assessment, shaping, organization and control. This study offers a comprehensive business model of the enterprise that systematically identifies key factors which influence business activity of the enterprise and provide value logic for doing business in the global economic environment

Improve the Sustainability of Internet of Things Through Trading-based Value Creation

Internet of Things (IoT) has been widely discussed over the past few years in technology point of view. However, the social aspects of IoT are seldom studied to date. In this paper, we discuss the IoT in social point of view. Specifically, we examine the strategies to increase the adoption of IoT in a sustainable manner. Such discussion is essential in today's context where adoption of IoT solutions by non-technical community is slow. Specially, large number of IoT solutions making their way into the market every day. We propose an trading-based value creation model based on sensing as a service paradigm in order to fuel the adoption of IoT. We discuss the value creation and its impact towards the society especially to households and their occupants. We also present results of two different surveys we conducted in order to examine the potential acceptance of the proposed model among the general public.Comment: arXiv admin note: substantial text overlap with arXiv:1307.819

Impact of inventory inaccuracy on service-level quality: A simulation analysis

This article discusses the impact of inventory inaccuracy on service-level quality in (Q,R) continuous review, lost-sales inventory models. A simulation model is built to study the behaviour of this kind of model exposed to an inaccuracy in inventory records as well as demand variability. We have observed an unusual result which goes against certain empirical practices in the SMEs that consist in hiking the inventory level proportionally to the data inaccuracy rate. A nonmonotone function shows that at the outset, the service-level quality is lowered as the inaccuracy rate increases but when the inaccuracy rate becomes much higher this quality is conversely enhanced. This relation can equally be observed given that stocktaking commences as soon as the threshold of decline in the service-level rate has been reached and when demand consequently dwindles. Finally, another noteworthy result also shows the same phenomenon between the function involving a level of safety stock defined by the simulation and the function between the service-level quality and the inventory inaccuracy. These different observed results are discussed in terms of both contribution to the (Q,R) inventory management policies in SMEs and of the limitations to this study.Continuous review inventory system, inventory inaccuracy, continuous model, discrete-time simulation
