Brain-Computer Interface (BCI) requires generating control signals for external device by analyzing and processing the internal brain signal. Cognitive or Mental State detection has its advantages in asynchronous BCI where the subjects are involved to the interface in response to some external stimulation. But the main problem is feature extraction and(More)
—Missing value imputation is one of the biggest tasks of data pre-processing when performing data mining. Most medical datasets are usually incomplete. Simply removing the cases from the original datasets can bring more problems than solutions. A suitable method for missing value imputation can help to produce good quality datasets for better analysing(More)
Clustering is the process of grouping similar data into a set of clusters. Cluster analysis is one of the major data analysis techniques and k-means one of the most popular partitioning clustering algorithm that is widely used. But the original k-means algorithm is computationally expensive and the resulting set of clusters strongly depends on the selection(More)

A wearable/on-body inverted-F antenna (brick shaped antenna elements) with low SAR for wireless medical devices is presented in this paper. The antenna covers 100% bandwidth of 2.45 GHz ISM band with a return loss bandwidth of 350 MHz (from 2.26 GHz to 2.61 GHz). Geometrical parameters of the antenna are optimised using parametric analysis in CST microwave(More)
An on-body/wearable planar antenna is designed for medical devices. The antenna operates in U-NII worldwide band having reflection coefficient bandwidth of 208 MHz with resonant frequency 5.50 GHz. Geometrical parameters of the antenna are optimized using parametric analysis in CST microwave studio. The antenna has very high gain of 8.79 dB and highly(More)
During recent decades, Bangladesh has experienced a rapid epidemiological transition from communicable to non-communicable diseases. Coronary heart disease (CHD), with myocardial infarction (MI) as its main manifestation, is a major cause of death in the country. However, there is limited reliable evidence about its determinants in this population. The(More)
BACKGROUND Overweight and obesity are increasing in low- and middle-income countries, while underweight remains a significant health problems. However, the association between double burden of nutrition and risk of adverse birth and health outcomes is still unclear in Bangladesh. The aim of this study was to determine the effect of maternal undernutrition(More)
