The interaction of body worn antennas with the human causes a significant decrease in antenna efficiency and shift resonant frequency. A slot small conductive box placed on has been shown to reduce these effects. specific absorption rate (SAR) is less than international health standards for most wearable due transmitter power. This paper reports linear relationship between power absorbed by biological tissues at different locations body, radiation based numerical modeling (r = 0.99). While...
In the present paper, energy performance of buildings forming a school centre in northwest Spain was analyzed using transient simulation model school, which developed with TRNSYS, software proven reliability field thermal simulations. A deterministic calibration approach applied to initial building adjust predictions actual data acquired during temperature measurement campaign. The under study were deteriorated conditions due poor maintenance over years, presenting big challenge for...
This paper investigates deteriorations in knee and ankle dynamics during running. Changes lower limb accelerations are analyzed by a wearable musculo-skeletal monitoring system. The system employs machine learning technique to classify joint stiffness. A maximum-entropyrate method is developed select the most relevant features. Experimental results demonstrate that distance travelled energy expended can be estimated from observed changes motions 5 km runs.
Analysis of the association between exposure to electromagnetic fields non-ionising radiation (EMF-NIR) and health in children adolescents is hindered by limited availability data, mainly due difficulties on assessment. This study protocol describes methodologies used for characterising EMF-NIR INMA (INfancia y Medio Ambiente- Environment Childhood) Project, a prospective cohort study. Indirect (proximity emission sources, questionnaires sources use geospatial propagation models) direct...
Future digital terrestrial television (DTT) systems are introducing revolutionary changes to their architectures and operation modes. One of the best examples is ATSC 3.0, which pushing incorporate Internet Protocol (IP) into protocol stack. This way, implementing new applications (e.g., target advertisement, connected cars, 4k/8k video content) closer than ever. Indeed, recent works have suggested designing an Inter-Tower Communications Network (ITCN) wireless In-band Distribution Link...
To know and to compare Inflammatory Bowel Disease (IBD) Incidence Prevalence rates in five areas of Asturias (Spain). We conducted a prospective epidemiologic study IBD the Province Liege (1 million inhabitants).We descriptive, populational, collaborative study, retrospective between 1954 1993 1994 1997. All patients diagnosed according standard protocol for case ascertainment definition IBD, aged 14 years or more are included, (Spain) (461,965 inhabitants).For period 1997, 1018 have been...
In-band full duplex (IBFD) communications are a potential solution to spectrum scarcity. IBFD offer greater spectral efficiency than traditional half-duplex by transmitting and receiving on the same frequency channel. However, operation requires overcoming challenge of eliminating self-interference coupled from transmit antenna receive subsystem. Knowledge characteristics loopback propagation channel makes it easier cancel out self-interference. Nevertheless, complex field trials required...
Radiofrequency fields are usually measured in order to be compared with electromagnetic exposure limits defined by international standardization organizations the aim of preserving human health. However, case WiFi technology, accurate measurement radiation coming from user terminals and access points is a great challenge due nature these emissions, which noncontinuous signals transmitted form pulses short duration. Most methodologies up now for determining levels use or take as reference...
Abstract The accurate location of an ingested transmitter requires array surface electric field sensors worn on the body for more than 24 h. small antenna (33 mm × 33 11 mm) consisting a conductive box with slot (28 7 pressed against centrally located feed probe was optimized to match impedance when torso. properties placed different locations torso were calculated using computer modeling and verified reflection measurements 6 participants body‐mass index between 17 27 kg/m 2 .

Human exposure to electromagnetic fields produced by two wearable antennas operating in the 2.4 GHz frequency band was assessed computational tools. Both were designed be attached skin, but they intended for different applications. The first antenna off‐body applications, i.e. communicate with a device placed outside body, while second model optimized located inside body. power absorption human tissues determined at several locations of adult male and female body models. maximum specific...
The epidemiologic analysis inflammatory bowel disease (IBD) is a powerful research tool to assess the contribution of environmental factors its etiology. IBD has been reported have varying frequencies in different parts world, and there seem be significant differences pattern clinical course. aim present study was Asturias (Spain).A descriptive epidemiological population based study, retrospective (1954-1993) prospective (1994-97), performed 1018 patients found, bigger than 14 years, IBD,...
This study is focused in the analysis of effects that impulsive and Gaussian noise have digital audio broadcasting.

This study presents an evaluation of human exposure levels due to WiFi signals. Up now, electromagnetic fields has been measured using methodologies and system configurations that account for the worst-case conditions. However, more accurate empirical data are needed, since most time worst case is too pessimistic be considered quantifying actual existing In this work, a novel methodology determine realistic values Access Point defined.

The effects of people movement in fixed indoor communications, known as temporal variation, are studied at 900 MHz and 2450 with undertaking experiments an office/laboratory environment. Intentional unintentional (natural activities such meeting, social gathering, etc.) variations were examined regard to various important parameters (i.e. mean received power, standard deviation, dynamic range fluctuation, level crossing rate, average fade duration, etc.). In particular, it is found that the...
This article describes a procedure for measuring and evaluating radio impulsive noise (IN) from specific source. A good knowledge of the caused by different sources is essential to plan services ensure quality service. Moreover, it necessary harmonize measurement methods achieve results that can be mutually compared. not only provides steps should followed make proper measurements, but also specifies appropriate parameters characterize IN when generated principal detailed description...
The pleural empyema has unusual origin at extralung causes. Then, is essential to identify the primary process in order obtain clinical setting control. Previously described, but even exceptional, this case report show an which it's was asymtomatic pyonephrosis, caused because of a big kidney calculus and discovery suspected by bacillus results. treatment must include appropriate antibiotic therapy thoracic drainage, also drain purulent accumulations perikidney area.
