Designing and implementing a portable ultrasound bone densitometer
Baghdad Science Journal20 - October - 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)

Songklanakarin Journal of Science and Technology15 - December - 2019
Direct Current (DC) is widely used in electrotherapy for disease treatment, with typical studies on the effect of DC on disease factors in the blood. The objective of this work was to study the effects of DC on human blood, and to determine the intensity of DC that safely flows through blood, and to know which components of blood are most affected by DC. The effects on the counts or levels of main blood components [Red Blood Cells (RBCs), White Blood Cells (WBCs), Platelets (PLTs), Hemoglobin (Hb), and Hematocrit (Hem)] were considered. DC intensities from 1 to 10 mA were passed through blood samples of ten healthy persons for periods of up to one hour. A blood test (blood count with white blood cell differential) was carried out before DC flow and after 5, 10, 15, 30, 45, and 60 minutes of treatment.

International Journal of Innovative Research in Computer and Communication Engineering13 - February - 2019
A Wireless Body Sensor Network (WBSN), is a network of sensors that worn or deployed on a person's body. This network plays an important role in medical field, where it allocates the vital information from the body and transmit it wirelessly to a central station to process it.We need to provide security and privacy for sent data because of the sensitivity of this information. In this paper, we propose an enhanced DNA cryptography technique that depending on nucleotides relationship concept to generate a data encrypted stream represent the sensors allocated data, so the intruder will not be able to modify this data while he is not knowing the technique of encryption, which provides a secure and private data transmission.
Controlling a Wheelchair Using Human-Computer Interaction
International Journal of Science and Research18 - March - 2018
In this paper, a prototype of an interactive wheelchair for quadriplegics and amputees is presented. Quadriplegics are people who are the victims of partial or complete paralysis of both upper and lower limbs; this is often the cause of a spinal cord injury or a disease in the area around the neck. The design presented in this paper is based on the field of Human-Computer Interaction, in which the face features of the quadriplegic are used to give him/her the opportunity to realize his/her needs. The face gestures are transformed to electrical signals using python programming language and the well-known OpenCv library for image processing. Signals are furthermore transmitted to an Arduino Uno microcontroller, which gives the orders to the wheelchair to move according to the patient’s wish. The design was evaluated and the results were analysed.
Reducing Energy Consumption in WBSNs using Statistic Test to detect Duplicated Data
International Journal of Innovative Research in Computer and Communication Engineering18 - February - 2018
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.
Fabrication Attack Effect on Medical Applications based on VANETs
International Journal of Computer Science Trends and Technology8 - March - 2017
In the context of expansion of using Vehicular Ad-hoc Networks-VANETs in the medical field around the world, studying the attacks on these networks becomes an urgent need to overcome these attacks and to serve a safe use in medical applications. In this paper, we will focus on a fabrication attack scenario which is one of the most dangerous attacks on VANETs’ reliability. Our simulations are built using VANET-SIM simulator, in which we study the fabrication attack using three different scenarios that is taking place in Lattakia city.

International Journal of Science and Research8 - March - 2017
Wireless Sensor Networks (WSNs) in medical applications. However, Wireless Body Area Networks (WBANs) promise to revolutionize health care in the near future. WBAN medical applications show great promise in improving the quality of life of people and satisfying many requirements of elderly people by enabling them to live safely, securely, healthily and independently. In this paper, we have simulated and analyzed well-known MANET routing protocols in WBAN of elderly long-term health monitoring system to determine which of them is much efficient to overcome MANET challenges in the medical applications. Various performance parameters used for comparison such as end-to-end delay, throughput, and packet loss ratio.
Download FileIncreasing Patients' Privacy While Using Search Engines and Social Media Websites
International Journal of Science and Research8 - March - 2017
Search engines and social media websites offer us great services, but they collect their users' information, which could be considered as a privacy violation. It requires some serious work to increase user's privacy level while using search engines services or surfing social media websites, and especially for patients, whom records are considered confident, and these websites are capable to create a medical profile for each of them. Our contribution in this paper is to propose a new method that enables us to increase users' privacy level while using existing search engines and social media websites without replacing them, in a way that disables those websites from accessing users' information.
