—Coexistence issues between IEEE 802.11b wireless communication networks and IEEE 802.15.4 wireless sensor networks , operating over the 2.4-GHz industrial, scientific, and medical band, are assessed. In particular, meaningful experiments that are performed through a suitable testbed are presented. Such experiments involve both the physical layer, through(More)
The deployment of a wireless control system must cope with a number of effects usually negligible in a wired scenario. To this aim, an experimental analysis on suitable prototypes and testbeds can readably offer a valid and rapid method to forecast the behavior of a real network. In this paper, performance measurement of industrial wireless sensor network(More)
BACKGROUND The AIBL study, which commenced in November 2006, is a two-center prospective study of a cohort of 1112 volunteers aged 60+. The cohort includes 211 patients meeting NINCDS-ADRDA criteria for Alzheimer's disease (AD) (180 probable and 31 possible). We aimed to identify factors associated with rapid cognitive decline over 18 months in this cohort(More)
Several recent studies have addressed the suitability of current wireless technologies for industrial communications which, frequently, are requested to cope with severe timing constraints. Most of the analysis that have lately appeared in the literature have focused on the performance offered by the lower layers of the communication stack. However, in(More)
In the modern wireless applications of factory automation, interference phenomena among near operating wireless networks can be the cause of severe performance degradation. To avoid this possibility and prevent deleterious system failures, simulations may offer a real and reliable solution. In this paper a new simulator is presented, allowing cross-layer(More)
BACKGROUND The rate of cognitive decline in Alzheimer's disease (AD) varies considerably between individuals. Predicting rapid cognitive decline might help clinicians provide prognostic information, select subjects for trial intervention and/or reduce costs. METHODS PubMed and PsycINFO were searched for all the English written studies published until the(More)
BACKGROUND All over Europe, an increased use of public health services has been noticed, particularly referring to access and hospitalization among elderly in the emergency department (ED). METHODS Prospective study at a university teaching hospital in Turin, northern Italy, recruiting subjects aged >65 years consecutively attending the medical ED during(More)
The performance of wireless local area networks supporting video streaming applications, based on MPEG-2 video codec, in the presence of interference is here dealt with. IEEE 802.11g standard wireless networks, that do not support QoS in according with IEEE 802.11e standard, are, in particular, accounted for and Bluetooth signals, additive white Gaussian(More)
