Location management is an essential service in mobile networks. It provides mechanisms for recording and querying location of mobile units in the network. This is needed for establishing calls to mobile units. In PCS networks, location management protocols such as IS-41 and GSM use statically defined Registration Areas (RAs) with two-level hierarchy of location databases. In this paper, we prop...

MSTDM is a variant of the Ethernet protocol that provides quality of service guarantees for voice. This protocol has been applied to LAN’s and CATV networks. Cellular networks are different: 1) Each cell has a base station: When mobile units communicate through the base station, frequency reuse increases and collisions are detected. 2) The objective is to connect mobile units to the communicati...

We consider the application of high volume information dissemination in broadcast based mobile environments. Since current mobile units accessing broadcast information have limited battery capacity, the problem of quick and energy-eecient access to data becomes particularly relevant as the number and sizes of information units increases. We propose several randomized and Huuman-encoding based i...

BACKGROUND The objective of this study was to explore the prevalence of microbiological contamination of mobile phones that belong to clinicians in intensive care units (ICUs), pediatric intensive care units (PICUs), and neonatal care units (NCUs) in all public secondary care hospitals in Kuwait. The study also aimed to describe mobile phones disinfection practices as well as factors associated...

From the late 1970s on, mobile software and hardware became a topic in computer science, introducing a set of features to traditional and distributed computer systems comprising issues like restricted resources, access rights, and varying connectivity. These features also apply to information systems—some with particular severity, like the resource poverty mismatching the large amount of data w...

The aim of the paper is to present the concept of mobile technology management in healthcare. The paper puts emphasis on application of mobile devices in provision of data indispensable for processing it by big data solutions and underlines relation between mobile technology and big data. Nowadays mobile devices generate large volumes of different types of data which can be analyzed by speciali...

Author's response to reviews: Dear Editor We have made all the formatting changes requeted. We believe that the paper is now ready for publication

Large structures, like manipulators for assembling the space station, are lightweight, and hence flexible. The structural flexibility results in significant elastic vibrations that are caused not only by exogenous perturbations but are also caused by maneuvers like slewing. For example, the Mobile Transporter Unit in the Space Station carries a flexible manipulator with payloads from one part o...

Problem definition: Achieving broad access to health services (a target within the sustainable development goals) requires reaching rural populations. Mobile healthcare units (MHUs) visit remote sites offer these However, limited exposure, literacy, and trust can lead sigmoidal (S-shaped) adoption dynamics, presenting a difficult obstacle in allocating MHU resources. It is tempting allocate res...
