Duplication and redundancy in WBSNs refer to collect the same vital signs, using sensor attached on the patient body, over a period of time. Transmitting duplicated and similar data well consume the sensor battery faster, and increase the traffic in the network. Therefore, in this paper, we introduce a lightweight technique to detect duplicates data, using statistic test to identify the similarity between the data. Then preventing the sensor from sending this duplicated data,which leads to increase the lifetime of the sensor, and reduce energy consumption.
Numerical Modeling of Renal Ionic Equilibrium for Implantable Kidney Applications
Baghdad Science Journal / 20 - مارس - 2023
The human kidney is one of the most important organs in the human body; it performs many functions and has a great impact on the work of the rest of the organs. Among the most important possible treatments is dialysis, which works as an external artificial kidney, and several studies have worked to enhance the mechanism of dialysate flow and improve the permeability of its membrane. This study introduces a new numerical model based on previous research discussing the variations in the concentrations of sodium, potassium, and urea in the extracellular area in the blood during hemodialysis. We simulated the differential equations related to mass transfer diffusion and we developed the model in MATLAB Simulink environment. A value of 700 was appeared to be the most appropriate as a mass transfer coefficient leading to the best permeability. The suggested models enabled to track the temporal variations of urine, K and Na concentrations in blood streamline.

Designing and implementing a portable ultrasound bone densitometer
Baghdad Science Journal / 20 - أكتوبر - 2023
Osteoporosis is a disease characterized by a low bone mass that increases the risk of fracture. The dual energy X-ray absorptiometry (DXA) bone densitometer is considered as the gold standard to measure bone mineral density (BMD)
