Recently, Wi-Fi-based human activity recognition using channel state information (CSI) signals has gained popularity due to its potential features, such as passive sensing and adequate privacy. The movement of various body parts in between Wi-Fi signals' propagation path generates changes the signal reflections refraction, which is evident from CSI variations. In this paper, we analyzed relationship activities properties (amplitude phase) on multiple receiving antennas discovered vary...

Epilepsy is a complex neurological condition that affects large number of people worldwide. Electroencephalography (EEG) measures the electrical activity brain and widely used in epilepsy diagnosis, but it usually requires manual inspection, which can be hours long, by neurologist. Several automatic systems have been proposed to detect still some unsolved issues. In this study, we dynamic method using deep learning model (Epileptic-Net) an epileptic seizure. The largely heterogeneous...

The listening or hearing impaired (deaf/dumb) people use a set of signs, called sign language instead speech for communication among them. However, it is very challenging non-sign speakers to communicate with this community using signs. It necessary develop an application recognize gestures actions languages make easy between the normal and deaf community. American Sign Language (ASL) one mostly used in World, considering its importance, there are already existing methods recognition ASL...

Human activity recognition (HAR) has emerged as a significant area of research due to its numerous possible applications, including ambient assisted living, healthcare, abnormal behaviour detection, etc. Recently, HAR using WiFi channel state information (CSI) become predominant and unique approach in indoor environments compared others (i.e., sensor vision) privacy-preserving qualities, thereby eliminating the need carry additional devices providing flexibility capture motions both...

Wearable sensors are monumental for human activity recognition. Researchers continuously inventing new technology to detect properly. Earable opens up interesting possibilities of monitoring personal scale behavioral activities. In this paper, we explore earables device 'eSense' multisensory stereo behavior analysis. We propose an recognition framework by exploiting eSense based multi-sensory device. It has a microphone, 6-axis inertial measurement unit, and dual-mode Bluetooth. use...

Background: Pediatric bladder stone disease is common in certain regions Asia. Traditionally, pediatric stones have been managing by open surgeries due to narrow caliber of the urethra. However a percutaneous suprapubic approach circumvents problem urethral these situations. Aim: The aim study was manage vesical calculus children mini-percutaneous cystolithotripsy (mPCCL). Patients and Methods: Twenty presenting with underwent (mPCCL) between January 2020 June. age ranged from 2 5 years all...

The classification of eye states (open or closed) has numerous potential applications such as fatigue detection, psychological state analysis, smart home devices controlling, etc. Due to its importance, there are a number works already reported in the literature using traditional shallow neural networks support vector machines, which have good accuracy (about 96%). However, is still enough space improve existing systems proper methods. major problem with classifiers that they depend on...

Cognitive impairment has a significantly negative impact on global healthcare and the community. Holding person’s cognition mental retention among older adults is improbable with aging. Early detection of cognitive will decline most significant extended disease to permanent damage. This paper aims develop machine learning model detect differentiate categories like severe, moderate, mild, normal by analyzing neurophysical physical data. Keystroke smartwatch have been used extract individuals’...

This cross sectional study was done in the Otolaryngology and Head-Neck Surgery Department of Banghabandhu Sheikh Mujib Medical University, Dhaka College Hospital Sir Salimullah during period September 2003 to February 2004. In this 30 patients sinonasal malignancy were studied observe clinicopathological pattern malignancy. The diagnosis made by detailed history, clinical, radiological histopathological examinations. majority within 40 70 years age (77%). Male female ratio 2.33:1. Majority...

Bangladesh has to import a significant quantity of mustard seeds meet its growing demand due the seeds' high oil content and oilcake, which is rich in protein used as animal feed. The impact zinc boron on (cv. BARI sarisha-14) output was investigated field experiment that carried out at Agricultural University (BAU), Mymensingh, from October 2017 March 2018. There are five levels (0, 2.5, 5, 7.5, 10 kilograms per hectare) 0.5, 1.0, 1.5, 2.0 kilogram this experiment. Three replications...

Digital Subtraction Angiography (DSA) is a modern technique which integrates digital data collection and computer processing to produce medical image. X-ray signals are detected electronically rather than on film then converted form be processed by before being displayed. DSA an integral investigation in the management of patients with neurovascular diseases. It basically used for diagnosis, but many instances, it may therapeutic same sitting. Indications diagnostic include both extracranial...

Primary Diagnosis of GI (gastrointestinal) malignancy is difficult and most the diagnostic tools were costly invasive. The clinical validity monitoring serum biomarker carcinoembryonic antigen (CEA) was assessed in 100 patients with gastric, duodenal colorectal adenocarcinomas a tertiary-level hospital Bangladesh. Sensitivity specificity test evaluated preoperatively. Patients clinically, radiologically, biochemically. Our study revealed that gastrointestinal (GI) as whole CEA had...

In signals of opportunity (SOPs)-based positioning utilizing low Earth orbit (LEO) satellites, ephemeris data derived from two-line element files can introduce increasing error over time. To handle the erroneous measurement, an additional base receiver with a known position is often used to compensate for effect when user terminal (UT). However, this approach insufficient long baseline (the distance between and UT) as it fails adequately correct Doppler shift measurement errors caused by...
