A Review and Analysis of Localization Techniques in Underwater Wireless Sensor Networks

In recent years, there has been a rapid growth in Underwater Wireless Sensor Networks (UWSNs). The focus of research in this area is now on solving the problems associated with large-scale UWSN. One of the major issues in such a network is the localization of underwater nodes. Localization is required for tracking objects and detecting the target. It is also considered tagging of data where sensed

Exercise for knee osteoarthritis pain : Association or causation?

Exercise is universally recommended as a primary strategy for the management of knee osteoarthritis (OA) pain. The recommendations are based on results from more than 100 randomized controlled trials (RCTs) that compare exercise to no-attention control groups. However, due to the inherent difficulties with adequate placebo control, participant blinding and the use of patient-reported outcomes, the

Ultra-wideband filtering antenna : Advancement and challenges

Ultra-wideband (UWB) is a short-distance radio communication technology that allows wireless networking inside the digital office and home with reliably high data rates across multiple devices [1]. However, some narrowband communication systems have existed in the UWB band, such as WiMAX (worldwide interoperability for microwave access) at 3.6 GHz, WLAN (wireless local area network) at 5.2 GHz, an

Power System Stabilization Tuning and Step Response Test of AVR : A Case Study

The voltage regulator keeps the generator voltage constant. The task of an automatic voltage regulator (AVR) is to maintain the stator voltage by changing the excitation current of the machine, resultant change in reactive power. AVR has many limiters like Volts per Hertz Limiter, Time delay overexcitation limiter, Instantaneous overexcitation limiter, under excitation limiter, stator current limi

Development of Efficient Prediction Model of FRP-to-Concrete Bond Strength Using Curve Fitting and ANFIS Methods

Externally bonded fiber-reinforced polymer (FRP) plates or sheets have become a common retrofitting approach for sustaining old reinforced concrete structures in the modern era. The capacity of FRP-strengthened structures cannot be accurately estimated because the bond strength between FRP and concrete surface is accurately unpredictable. Various studies are available in the literature to predict

The Use of Computational Geometry Techniques to Resolve the Issues of Coverage and Connectivity in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) enhance the ability to sense and control the physical environment in various applications. The functionality of WSNs depends on various aspects like the localization of nodes, the strategies of node deployment, and a lifetime of nodes and routing techniques, etc. Coverage is an essential part of WSNs wherein the targeted area is covered by at least one node. Computa

Contact allergy in Swedish professional ice hockey players

Background: Professional ice hockey players may contract irritant and allergic contact dermatitis. Aims: To investigate the presence of contact allergy (CA) in professional ice hockey players in Sweden. Methods: Ten teams from the two top leagues were assessed for potential occupational exposure to sensitizers. Exactly 107 players were patch tested with an extended baseline series and a working se

Synchronous Condensing Mode Operation of Hydropower Plants

Energy is the essential requirement of humans. It plays a major role in the development of any country. The present status of crude oil import of India in the financial year 2018-19 was around 22,64,98,000 MT of Rs. 7,83,183 crore and other fuels like LPG, MS, Naphtha, ATF, etc. were around 3,33,48,000 MT of Rs. 1,13,665 crore [1] and the total installed capacity of India is around 3,65,981.00 MW

Effect of wavelet filters on SFQ encoder performance for medical images

This paper is focused on analysing the effect of wavelet filters on Space frequency quantization (SFQ) coder performance. SFQ is a new class of image coding algorithms coupling standard scalar quantization of frequency coefficients with tree-structured quantization (related to spatial structures) has attracted wide attention because its good performance appears to confirm the promised efficiencies

Performance monitoring of kaplan turbine based hydropower plant under variable operating conditions using machine learning approach

Silt is the leading cause of the erosion of the turbine's underwater components during hydropower generation. This erosion subsequently decreases the machine's efficiency. The present study aims to develop statistical correlations for predicting the efficiency of a hydropower plant based on the Kaplan turbine. Historical data from a Kaplan turbine-based hydropower plant was employed to create the

IoT based reliable and efficient vaccines monitoring and distribution system

A successful vaccination program depends on secure vaccine storage as well as safe and effective vaccine delivery. An Internet of Things (IoT) based vaccine distribution and monitoring model, which is used to transport and monitor vaccines to locations where they will be properly kept for eventual use, is developed and tested. Coronavirus (COVID-19) was first identified in December 2019 in Wuhan c

IoT based microcontroller operated UV germicide system

With the rise of the COVID-19 pandemic across the globe, people have come to understand the requirement of sanitation. However, other than the personal hygiene, sanitization of all the appliances (like mobile phone, wristwatch, wallet, eye wear, etc.) has become very important. Therefore, the requirement of germicides is being increased to sanitize all the appliances. A few germicides comprise che

IoT based sensor operated automatic potion (SOAP) dispenser

Previously, there were physically operated hand dispensers that needed to be contacted every time we needed to apply the sanitizer. Due to the outbreak of the COVID-19, the importance of alcohol-based sanitizers has come up. As there are chances of spreading the viruses through contact surfaces, foot-operated dispensers have been developed to avoid contact between hands and hand dispensers. For th

Welfare justifications and responsibility in political decision making - The case of Nudging*

Nudging, i.e. the framing of decision environments to exploit known behavioral biases in order to induce certain outcomes, has received considerable attention as a potential policy tool in recent years. Motivated as preserving freedom of choice while making people better off according to their own judgment, nudging seemingly comes at fairly little responsibility for the nudger, i.e. policy makers,

ML-Based Computational Model to Estimate the Compressive Strength of Sustainable Concrete Integrating Silica Fume and Steel Fibers

Concrete is one of the most commonly used construction material on the earth after water. The compressive strength of concrete is an important parameter and is considered in all structural designs. Production of the cement is directly proportional to carbon emissions. The cement content in the concrete can be partially replaced with waste materials like steel fibers, silica fumes, etc. Calculating

Neural Network Based Algorithm to Estimate the Axial Capacity of Corroded RC Columns

Columns are the important structural elements to transfer the superstructures load to the foundation. Deterioration and degradation of the structural elements is the critical issue facing by the entire world. Corrosion is one of the most common cause responsible for the deterioration. To maintain structural safety as well as serviceability, it is important to estimate the residual capacity of the
