Intracavity absorption spectroscopy is a strikingly sensitive technique that has been integrated with a two-wavelength setup to develop a sensor for human breath.Various factors are considered in such a scenario,out of which Relative Intensity Noise(RIN)has been exploited as an important parameter to characterize and calibrate the said setup.During the performance of an electrical based assessment arrangement which has been developed in the laboratory as an alternative to the expensive Agilent setup,the optical amplifier plays a pivotal role in its development and operation,along with other components and their significance.Therefore,the investigation and technical analysis of the amplifier in the system has been explored in detail.The algorithm developed for the automatic measurements of the system has been effectively deployed in terms of the laser’s performance.With this in perspective,a frequency dependent calibration has been pursued in depth with this scheme which enhances the sensor’s efficiency in terms of its sensitivity.In this way,our investigation helps us in a better understanding and implementation perspective of the proposed system,as the outcomes of our analysis adds to the precision and accuracy of the entire system. 展开更多

The Internet of Things(IoT)is a concept that refers to the deployment of Internet Protocol(IP)address sensors in health care systems to monitor patients’health.It has the ability to access the Internet and collect data from sensors.Automated decisions are made after evaluating the information of illness people records.Patients’health and well-being can be monitored through IoT medical devices.It is possible to trace the origins of biological,medical equipment and processes.Human reliability is a major concern in user activity and fitness trackers in day-to-day activities.The fundamental challenge is to measure the efficiency of the human system accurately.Aim to maintain tabs on the well-being of humans;this paper recommends the use of wireless body area networks(WBANs)and artificial neural networks(ANN)to create an IoT-based healthcare framework for hospital information systems(IoT-HF-HIS).Our evaluation system uses a server to estimate how much computing power is needed for modeling,and simulations of the framework have been done using data rate and latency requirements are implementing the energy-aware technology presented in this paper.The proposed framework implements several hospital information system case studies by building a time-saving simulation environment.As the world’s population ages,more and more people suffer from physical and emotional ailments.Using the recommended strategy regularly has been proven user-friendly,reliable,and cost-effective,with an overall performance of 95.2%. 展开更多

In this paper,a system supporting behavioral therapy for autistic children is presented.The system consists of sensors network,base station and a brooch indicating person's ernotional states.The system can be used to measure values of physiological parameters that are associated with changes in the emotional state.In the future,it can be useful to inform the autistic child and the therapist about the emotional state of the interlocutor objectively,on the basis of performed measurements.The selected physiological parameters were chosen during the experiment which was designed and conducted by authors.In this experiment,a group of volunteers under con-trolld conditions was exposed to a stressful situation caused by the picture or sound.For each of the volunteers,a set of physiological parameters,was recorded,including:skin conductance,heart rate,peripheral temperature,respiration rate and electromyography.The bio statistical analysis allowved us to discern the proper plhysiological paraneters that are most associated to changes due to emotional state of a patient,such as:skin conductance,temperatures and res-piration rate.This allowed us to design electronic sensors network for supporting behavioral therapy for children with autism. 展开更多

The occurrence of potassium dichromate in food poses serious health risks,including cancer and skinrelated issues.Conventional sensing methods,known for their poor sensitivity,low selectivity,and high costs,highlight the need for improved detection methods.This study addresses this gap by exploring the use of carbon quantum dots(CQDs)synthesized from Tamarindus indica leaves through an eco-friendly hydrothermal approach for the detection of potassium dichromate.Briefly,the synthesized CQDs underwent spectroscopic characterizations.Following this,the CQDs-based sensor was assessed for key analytical parameters such as sensitivity,selectivity,and the analysis of spiked milk samples to detect potassium dichromate.As a result,analyses of particle size and zeta potential confirmed the formation of stable,nanosized CQDs.The introduction of potassium dichromate led to the quenching of CQDs’fluorescence,likely attributed to mechanisms such as the inner filter effect(IFE)and fluorescence resonance energy transfer(FRET).The established linearity range and limit of detection were determined to be 50-500 and 148μmol/L,respectively.Confirmation of the sensor’s practicality was obtained through the analysis of spiked samples,suggesting that CQDs could potentially serve as a viable alternative for detecting potassium dichromate in milk samples in the future. 展开更多
