Drug traffickers are active and always looking for new ways to mix drugs to avoid their detection and identification. One example is black cocaine, which is a mixture of cocaine base and cocaine hydrochloride and other additional substances. It is challenging for investigators to accurately identify the test for investigative purposes without conducting an on-site evaluation. Presumptive drug test...
In this paper, we described the practical application of data mining methods for estimation of survival rate and disease relapse for breast cancer patients. A comparative study of prominent machine learning models was carried out and according to the achieved results we concluded that the classifiers obviously learn some of the concepts of breast cancer survivability and recurrence. These algorithms...
In this paper, we propose an acoustic signal synthesizing algorithm called two-step reconstruction algorithm based on the geometrical information of ROI(region of interest). Even though we apply the same conventional reconstruction algorithm, we can obtain the better image quality of ROI by using the proposed two-step reconstruction algorithm. We comment on the mathematical minor mistakes in applying...
Preoperative evaluation of liver future remnant volume is essential for liver oncologic and transplantation surgery. Segmentation of liver imaging studies allow for an excellent liver volumetric analysis. We developed a hybrid liver segmentation algorithm which is based on thresholding by pixel intensity value. The algorithm consists of a semiautomatic and an automatic part. The aim of this prospective...
In this paper we present a novel approach in multi-scale muscle modeling based on finite element method and Huxley crossbridge kinetics model. In order to determine the mechanical response of a muscle, we implement basic mechanical principles of motion of deformable bodies using finite element method. Constitutive properties of muscle are defined by the number of molecular interconnections between...
Since multi-scale models of muscles rely on the integration of physical and biochemical properties across multiple length and time scales, these models are highly CPU consuming and memory intensive. Therefore, their practical implementation and usage in real-world applications is limited by their high requirements for computational power. There are various reported solutions to the problems of the...
This paper offers new results from a study of mixed-mode oscillations, with application to both neural and mechanical systems. It is initially shown that the Fitzhugh-Nagumo model, which is itself a simplification of the previous electrophysiological model of Hodgkin and Huxley, has a direct analogue in the form of the model for a bistable spring mass system. This system is then shown to exhibit three...
Automated cell classification in Indirect Immunofluorescence (IIF) images has potential to be an important tool in clinical practice and research. This paper presents a framework for classification of Human Epithelial Type 2 cell IIF images using convolutional neural networks (CNNs). Previuos state-of-the-art methods show classification accuracy of 75.6% on a benchmark dataset. We conduct an exploration...
Data produced out of microarray experiments are of great use for the physician when it is presented in a meaningful manner. This paper proposes hybrid intelligent methods for addressing the challenges in analyzing the microarray data. The concept of fuzzy and rough set is hybridized with FInformation (FRFI) for gene selection. An optimal fuzzy logic based classifier (FLC) is developed for sample classification...
Eimeria is an internal animal parasite that causes serious diseases and animal death, and reduces animal productivities. Eimeria has more than one species for every single genus of animals. An early diagnosis of Eimeria infection is usually achieved by examining fecal microscopy images. As Eimeria oocysts vary in terms of shapes, sizes and textures, they can be detected by measuring differences in...
Gait analysis is nowadays considered, as a promising contributor towards early detection of cognitive and physical status deterioration when it comes to elderly people. However, the majority of recent efforts on indoor gait analysis methodologies are limited as they only exploit the average walking speed. Applying density based clustering algorithms on indoor location datasets could accelerate context...
Mandible internal fractures are a common injury because of the mandible's lack of structural support. For the treatment of such injuries various fixation elements are used. In order to improve quality of the orthodontists interventions anatomically correct and geometrically accurate customized implants are necessary. In this paper an example of accurate geometrical model of the customized plate implant...
In the past, genome sequence databases had used main memory indexing, such as the suffix tree, for fast sequence searches. With next generation sequencing technologies, the amount of sequence data being generated is huge and main memory indexing is limited by the amount of memory available. K-mer based techniques are being more used for various genome sequence database applications such as local alignment...
In this research, a web-based simulator is developed, which can be used for generating image sequences of moving spermatozoa cells. It can be used for assessment of multiple object tracking algorithms, especially Computer Aided Sperm Analysis (CASA) systems. The developed software has many useful parameters such as blurring images or adding noise and it also gives full control of sperm counts and...
Discovering useful patterns in medical time series data such as EEG and EMG recordings is an important step for gaining useful insights into the data and medical problem under investigation, and for building accurate classifiers. However, pattern mining algorithms often require a binning step, which maps the time series data into a representation in terms of discretized values, in order to discover...
There is an undisputed need for increased portability and flexibility in diagnostic ultrasound imaging due to the continuously evolving point of care (POC) clinical applications. In order to meet this growing need numerous portable ultrasound systems have been proposed. The design of portable systems is a very challenging task, especially for volumetric imaging system which utilize transducers with...
