The next generation of industrial advancement which is referred as Industry 4.0 aims to inter-connect and computerize the traditional industrys such manufacturing. objective in make factories smart enough terms improved adaptability, resource efficiency well integration supply demand processes between factories. Wireless communication will play a key role enabling systems technologies. In this paper we focus discussion on some wireless challenges that need be met for era. We look at how 5...
In any vehicular adhoc network, there is always a possibility of incorrect messages being transmitted either due to faulty sensors and/or intentional malicious activities. Detecting and evicting sources such misbehavior an important problem. We observe that the performance detection schemes will depend on application under consideration mobility dynamics detecting vehicle. Further, underlying tradeoff in algorithm balance between False Positives Negatives; one would like detect as many...
The 2013-16 Ebola virus disease epidemic in west Africa caused international alarm due to its rapid and extensive spread resulting a significant death toll social unrest within the affected region. large number of cases provided an opportunity study long-term kinetics Zaire ebolavirus-specific immune response survivors addition known contacts those infected with virus.
Abstract Purpose To use a volume‐selective 3D turbo spin echo (TSE) technique to image the carotid artery wall and measure distensibility. Materials Methods A high‐resolution TSE sequence has been developed. Volume selection is accomplished by orthogonal gradients for 90° 180° excitations allows volume of vessel be imaged in relatively short time. The developed allow imaging at any defined phase cardiac cycle so that vascular function distensibility can studied. Results Scan efficiency...
Background Despite several studies on the seroprevalence of antibodies against Crimean-Congo Haemorrhagic Fever virus (CCHFV) from humans and cattle in Nigeria, detailed investigation looking at IgG IgM have not been reported. Additionally, there no confirmed cases human CCHFV infection reported Nigeria. Principal Findings Samples sera (n = 1189) collected four Local Government Areas Borno State (Askira/Uba, Damboa, Jere Maiduguri) were assessed for presence antibodies. The positivity rates...
Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease associated with high case fatality rate and transmitted mainly by Hyalomma marginatum. The geographical distribution of H. marginatum covers most the Western Mediterranean basin. We aimed to investigate whether CCHF virus (CCHFv) circulating in Tunisia. Samples from unexplained acute febrile patients (n = 181) risk group humans, slaughter workers 38), were collected summer 2014 analyzed for exposure CCHFv using serological tests...
Internet of Things adoption in traditional and slow changing industrial plants such as power, water, oil-gas chemical has proven to be beneficial providing business value by transforming the way data is utilized decision-making visualization. Typical IoT use cases involve acquiring from sensor devices plant communicating same internet for local or remote monitoring control. The acquisition an thus becomes paramount acquired used bringing out underlying knowledge system. typically requires a...
Rift Valley fever virus (RVFv) is capable of causing dramatic outbreaks amongst economically important animal species and severe symptoms mortality in humans. RVFv known to circulate widely throughout East Africa; serologic evidence exposure has also been found some northern African countries, including Mauritania. This study aimed ascertain whether circulating regions beyond its geographic range. Samples from febrile patients (n = 181) nonfebrile healthy agricultural slaughterhouse workers...
Crimean-Congo hemorrhagic fever virus (CCHFV) is a highly transmissible human pathogen. Infection often misdiagnosed, in part because of poor availability data disease-endemic areas. We sampled 150 apparently healthy ruminants throughout Nigeria for seropositivity and detected virus-specific IgG cattle (24%) goats (2%), highlighting the need further investigations.
Secure communication of time critical information in V2V networks is expected to be achieved via a robust infrastructure that provides security related services at all times. This paper explores the dependence performance secure communications on mechanisms used by infrastructure. We propose and analyze metric termed confidence (CoS) can assist accepting/dropping message each node communications.
Abstract Purpose To assess the interstudy reproducibility of a three‐dimensional volume‐selective, fast spin echo (FSE) magnetic resonance technique for assessment carotid artery wall volume, which is marker total plaque volume. Materials and Methods Interstudy was evaluated in 10 subjects with evidence atherosclerotic disease on Doppler ultrasonography. Subjects were scanned twice an interscan time one hour to four days. The imaged cross‐section, arterial volume (TWV) calculated by...
Abstract Purpose To improve 3D volume‐selective turbo spin echo (TSE) carotid artery wall imaging by incorporating navigators to reduce artifacts caused swallowing. Materials and Methods Images were acquired on a Siemens Magnetom Sonata 1.5T scanner. TSE scans of the arteries in six healthy volunteers. A cross‐pair navigator placed back tongue was used detect swallowing movement. Two patterns tested: 1) single swallow approximately halfway through scan time, at center k z , 2) repeated as...
There is recent evidence suggesting that rosiglitazone increases death from cardiovascular causes. We investigated the direct effect of this drug on atheroma using 3D carotid magnetic resonance. A randomized, placebo-controlled, double-blind study was performed to evaluate treatment atherosclerosis in subjects with type 2 diabetes and coexisting vascular disease or hypertension. The primary endpoint change baseline 52 weeks arterial wall volume, reflecting plaque burden, as measured by...
Becker muscular dystrophy is a rare cause of dilated cardiomyopathy. A case reviewed in which cardiovascular magnetic resonance showed previously unreported findings extensive mid-myocardial late gadolinium enhancement. Similar detection enhancement conjunction with other uses may contribute significantly to the diagnosis and management patients this unusual important diagnosis.
The needs of Indian rural telecom, and the economics currently available broadband access technologies, motivate a new system for access, which we call WiFiRe (WiFi extension). leverages widely available, highly cost-reduced, WiFi chipsets. We, however, retain only PHY from these chipsets propose single-channel, multisector, TDD MAC using directional antennas. proposed is similar to WiMAX in several respects. In this article our approach, describe architecture MAC, analyse spatial reuse,...
Despite its geographical spread, the epidemiology of Crimean-Congo haemorrhagic fever (CCHF) in Sub-Saharan Africa is incompletely understood and occurrence Mozambique unknown. This study was conducted with aim investigating CCHF virus (CCHFV) among febrile patients attending an outpatient appointment clinic at three separate primary health care centres Mozambique.Serum samples were collected from a total 300 aged >5 years who recruited between March 2015 2016 Mozambique. Each patient...
