Abstract The study was aimed to evaluate the performance of a newly developed spectroscopy-based non-invasive and noncontact device (SAMIRA) for simultaneous measurement hemoglobin, bilirubin oxygen saturation as an alternative invasive biochemical method blood sampling. accuracy assessed in 4318 neonates having incidences either anemia, jaundice, or hypoxia. Transcutaneous bilirubin, hemoglobin values were obtained by instrument which corroborated with tests expert clinicians. is trained...
The design of the memristor emulator, which has found widespread applications in analog computation, neuromorphic and biological systems, communications, etc., is much sought for. In this article, a resistorless electronically tunable grounded floating emulator by employing current-mode (CM) building blocks: operational transconductance amplifier (OTA) voltage differencing buffered (VDBA) been proposed. proposed emulators can be configured as incremental decremental operations. robustness...
Increasing demand of high-speed portable modules for multimedia applications has motivated the development hardware-based solutions image processing applications. Most nonrigid registration algorithms are found to be unsuitable hardware implementation because their nonlinearity and computationally intensive nature. In this paper, an algorithm based on Demons approximation is proposed. The been simulated in MATLAB results show a 15% improvement peak-signal-to-noise-ratio with 17% reduction...
We developed an integrated device composed of a single-probe Electroencephalogram (EEG) and Charge Coupled Device (CCD) based motion sensors for objective measurement Attention-deficit Hyperactivity Disorder (ADHD). While the attention-deficit hyperactivity disorder (MAHD) relies on EEG signal assessment attention during given structured task, CCD sensor depicts movement pattern subjects engaged in continuous performance task. A statistical analysis patterns was performed, accuracy completed...
Image registration is a technique used for aligning two different images taken at times and/or from viewing and imaging setups/modalities. A key challenge medical image to minimize computation time reduce alignment errors. The Demons deformation algorithm has been extensively registration. In this paper we present modifications that runtime while giving good deformation.
Histogram computation is a fundamental task often encountered in image processing systems. This plays an important role various applications like registration, show-through correction method scanned of duplex mode printed document, etc. Mutual information (MI) one the best metric for intensity-based multimodality registration. Similarity measurement between images consumes significant amount execution time Computation MI requires to obtain individual and joint histogram two images. Typical...
In this work, second order inverse lowpass and bandpass filter are presented using operational transresistance amplifier (OTRA) as a basic building block. This work has been done two OTRA passive components to realize the filters. The working of proposed filters is verified by SPICE simulation CMOS model with 0.5 μm technology. Monte Carlo analysis noise was also performed in SPICE.
Three novel configurations of second order inverse band reject filters (IBRFs) are proposed in this work by using a single operational transresistance amplifier (OTRA). The working the verified simulation implementing 180 nm CMOS model OTRA SPICE and also hardware with AD844AN IC. Theoretical frequency response characteristics all three match very well simulated characteristics. Layout configuration has been implemented Analog Design Environment (ADE) tool cadence virtuoso to study...
No rigid registration helps to recover local warping which occurs during image acquisition. The speed of operation is one the bottlenecks in nonrigid addressed by only a few. In present paper an efficient Demons approach presented not increases task, but also retains performance algorithm.
The potentiality of Förster resonance energy transfer (FRET) for studying molecular interactions inside biological tissues with improved spatial (Angström) and temporal (picosecond) resolution is well established. On the other hand, efficacy diffuse reflectance spectroscopy (DRS) that uses optical radiation in order to determine physiological parameters including haemoglobin, oxygen saturation known. Here we have made an attempt combine picosecond-resolved FRET show improvement exploration...
Image registration is the process of aligning two images different modalities or acquired at times using same modality. Minimization alignment error with less computation a challenging task especially in medical imaging system. To deform image for reference image, Demons deformation algorithm has been used extensively. This paper presents some modification which helps to reduce as well runtime by 25% and 33% respectively.
Abstract This article presents three different higher‐order inverse filter (IF) configurations using current differencing buffered amplifier (CDBA) as an active component and a few passive elements. The topology can be used to synthesize fourth‐order low pass (FO‐ILPF), band (FO‐IBPF), all‐pass (FO‐IAPF) suitable admittance combinations. PSPICE simulations verify the functionality of proposed IFs with CMOS‐based CDBA 180 nm technology. theoretical analysis simulated results are also carried...

The current COVID-19 pandemic has increased the use of facial masks globally, which late have registered their presence as a part our civilization. N95 mask is one most popular choices under situation. However, available cannot provide breathing comfort for an extended period, results in rebreathing exhaled air that CO2 rich, and remains space respirator. Furthermore, problems like moisture settlement on covered area face due to multiple layers fabric-like material causes significant...
