The problem of denoising iris pictures for iris identification systems will be discussed, as well as a novel solution based on wavelet and median filters. Different salt and pepper extraction algorithms, as well as Gaussian and speckle noises, were used. Because diverse sounds decrease picture quality during image collection, noise reduction is even more important. To reduce sounds like salt and pepper, Gaussian, and speckle, filtering (median, wiener, bilateral, and Gaussian) and wavelet transform are utilised. Provide better results as compared to other ways. A study of several efficiency indicators such as peak signal-to-noise ratio (PSNR) and mean squared error will be used to demonstrate the superiority of the proposed technique (MSE).
Wireless sensor networks are limited by the vast majority of goods with limited resources. Power consumption, network longevity, throughput, routing, and network security are only a few of the research issues that have not yet been addressed in sensor networks based on the Internet of Things. Prior to becoming widely deployed, sensor networks built on the Internet of Things must overcome a variety of technological obstacles as well as general and specific hazards. In order to address the aforementioned problems, this research sought to improve rogue node detection, reduce packet latency/packet loss, increase throughput, and lengthen network lifetime. Wireless energy harvesting is suggested in the proposed three-layer cluster-based wireless sensor network routing protocol to extend the energy lifespan of the network. For the purpose of recognising and blacklisting risky sensor node behaviour, a three-tier clustering architecture with an integrated security mechanism is suggested. This clustering approach is cost-based, and the sink node selects the cluster and grid heads based on the cost function’s value. With its seemingly endless potential across a wide range of industries, including intelligent transportation, the Internet of Things (IoT) has gained prominence recently. To analyse the nodes and clustering strategies in IoT, the suggested method PSO is applied. A plethora of new services, programmes, electrical devices with integrated sensors, and protocols have been produced as a result of the Internet of Things’ explosive growth in popularity.
Wireless body area networks (WBANs) have gotten a lot of interest as the need for wearable gadgets like smart watches, eyewear, and clothing grows. WBAN applications need the use of a conformal antenna. A low-profile IR-UWB antenna and an all-textile higher order mode circular patch antenna for omnidirectional radiation were used to meet this need. To achieve maximum power output, researchers need to maintain the antenna's efficiency as high as feasible while designing a lightweight antenna for wireless power transfer. The need for tiny textile antennas with high gain and broadband features has risen in response to the fast growth of wireless power transfer. Microstrip patch antennas provide a number of advantages, including a cheap cost, a low profile, a light weight, and a simple manufacturing method. Increases in substrate thickness, antenna efficiency, use of a low dielectric substrate, and different impedance matching and feeding techniques are all examples of ways to enhance antenna bandwidth.
In recent years, antenna design has received a lot of attention [...]
Medical image collaboration may be accomplished for medical practise and education by bringing the idea of CSCW to the medical imaging field. Medical pictures may be examined and diagnosed by groups of people, and individuals can talk about them on a chat system while exchanging visual image data on their terminals. The process of generating visible pictures of inside body structures for scientific and medicinal research and therapy, as well as a visible view of the function of internal tissues, is known as medical imaging. The goal of this procedure is to identify and treat disorders. This procedure generates a database of the organs' normal structure and function, making it simple to spot abnormalities. Organic and radiological imaging, using electromagnetic energy (X-rays and gamma), sonography, magnetic scopes, and thermal and isotope imaging are all part of this process.
<p>The implementations of the microstrip patch antenna for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) are analysed in the literature in this research. Dual or multiband antenna has played a significant part in meeting the expectations of wireless service in this quickly developing world of wireless communication. Basically, a transitory guide, an antenna is a device that emits or absorbs radio waves. Numerous benefits exist for microstrip patch antennas, including affordability, portability, simplicity of construction, and compatibility with integrated circuits. This has several important uses in the military, radar, mobile communications, global positioning system (GPS), remote sensing, and more. In mobile devices like portable computers and smart phones, WLAN and WiMAX are often used.</p>
The importance of various AI concepts for telemedicine aims, as well as their current and prospective future applications, will be examined in this article. Patients will be observed, healthcare information technology will be discussed, intelligent computer diagnosis will be discussed, simulation and training systems will be examined, and data analysis and collaboration will be investigated. Artificial intelligence (AI) has been around for decades and is employed in a broad range of applications. In healthcare, the technology can be used in a variety of ways, such as providing a system for analysing medical data to identify sources of errors and developing solutions based on existing procedure results, as well as improving procedures by incorporating computerised intelligence into medical devices and tools. The capacity to spot patterns quickly and with calculated accuracy aids in finding the best practice and treatment options for medical therapies.
