The advances in localization based technologies and the increasing importance of ubiquitous computing context-dependent information have led to a growing business interest location-based applications services. Today, most application requirements are locating or real-time tracking physical belongings inside buildings accurately; thus, demand for indoor services has become key prerequisite some markets. Moreover, address inadequacy global positioning system closed environment, like buildings....

In the recent past, a significant increase has been observed in use of underwater wireless sensor networks for aquatic applications. However, face several challenges including large propagation delays, high mobility, limited bandwidth, three-dimensional deployments, expensive manufacturing, and energy constraints. It is crucial to mitigate all these limitations primarily caused by harsh environment. To address some pertinent challenges, adaptive hop-by-hop cone vector-based forwarding...

Face recognition (FR) technology has numerous applications in artificial intelligence including biometrics, security, authentication, law enforcement, and surveillance.Deep learning (DL) models, notably convolutional neural networks (CNNs), have shown promising results the field of FR.However CNNs are easily fooled since they do not encode position orientation correlations between features.Hinton et al. envisioned Capsule Networks as a more robust design capable retaining pose information...

In large indoor environments, accurate positioning and tracking of people autonomous equipment have become essential requirements. The application increasingly automated moving transportation units in spaces demands a precise knowledge their positions, for both efficiency safety reasons. Moreover, satellite-based Global Positioning System (GPS) signals are likely to be unusable deep spaces, technologies like WiFi Bluetooth susceptible signal noise fading effects. For these reasons, hybrid...

In indoor environments, WiFi (RSS) based localization is sensitive to various fading effects and noise during transmission, which are the main causes of errors that affect its accuracy. Keeping in view those effects, positioning systems on a single technology ineffective performing accurate localization. For this reason, trend toward use hybrid (combination two or more wireless technologies) indoor/outdoor scenarios for getting better position This paper presents technique implement adopts...

Accurate location or positioning of people and self-driven devices in large indoor environments has become an important necessity The application increasingly automated self-operating moving transportation units, spaces demands a precise knowledge their positions. Technologies like WiFi Bluetooth, despite low-cost availability, are sensitive to signal noise fading effects. For these reasons, hybrid approach, which uses two different sources, proven be more resilient accurate for the...

In indoor environments, accurate location or positioning becomes an essential requirement, driven by the need for autonomous moving devices, to identify position of people in large spaces. Single technology schemes which use WiFi and Bluetooth are affected fading effects as well signal noise, providing inaccuracies estimation. Hybrid locating have been used situations scenarios order improve accuracy. Hence, this paper proposes a hybrid scheme (technique) implement fingerprint-based...

Studies that have been conducted demonstrated does not affect spread of hyperbaric bupivacaine. This study aimed find correlation between spinal column length term parturients and highest level after anaesthesia.Methods: The authors studied 60 singleton American Society...

The expansion of Wireless Local Area Networks (WLAN) especially the advances in localization based technologies has generated a growing interest an indoor Positioning Systems (WPS) on WLAN infrastructure. This paper presents preliminary study two positioning techniques, known as fingerprinting and clustering technique by leveraging existing Network infrastructure area with approximately 95% coverage. Initial results indicate that both able to perform localization. Several enhancement...

Underwater or Acoustic propagation is characterized by three major factors: attenuation that increases with signal frequency, time-varying multipath propagation, and low speed of sound. The background noise, often as Gaussian, not white, but has a decaying power spectral density. Channel capacity depends on the distance, may be extremely limited. As acoustic best supported at frequencies, an communication system inherently wideband bandwidth negligible respect to its center frequency....

This paper is concerned with the investigation of a possible working principle microwave sensor for measurement water levels in plastic pipes. According to research, most current sensors level require an unobstructed path from and therefore, integrity pipes, which flows, will be compromised. The proposed work at frequencies measure flow pipes outside. would non-invasive non-intrusive. A beam energy antenna directed towards surface within pipe reflection due isolated knowledge dimensions...
