High-sensitivity C-reactive protein (hs-CRP) performs important roles on the onset of metabolic syndrome and cardiovascular diseases (CVD), but little is known about association between hs-CRP and obesity-related metabolic abnormalities in young people without classical CVD risk factors. It thus motivated us to investigate association among hs-CRP, body fat mass (FM) distribution, and other cardiometabolic...
This paper addresses the modeling and attitude control of a novel shrouded floating wind turbine with hinged structure in harsh environmental conditions. Firstly, SimMechanics™ is applied to model the mechanical components of the wind turbine system. Secondly, the wave- and wind-loads acting on the system are respectively calculated based on Morison's equation and blade element momentum theory. Controllers...
Applying Dynamic Voltage and Frequency Scaling (DVFS) in real-time systems is not a trivial task. Real-Time tasks are bounded to timing constraints in such a way that a simple performance degradation may cause the system to totally fail. Thus, this work aims at gathering two DVFS approaches (intra and inter-tasks) to define a methodology for optimizing energy consumption in hard real-time systems...
The cross-correlation coefficient (CC) was used to estimate the effects of muscular voluntary contraction (MVC) and fibres inclination. The study was based on simulated surface electromyographic (sEMG) signals generated in a cylindrical multi-layer volume conductor (bone, muscle, fat and skin) and detected by longitudinal single differential (LSD), inverse binomial of order two (IB2) and maximum kurtosis...
In this article we study the combustion characteristics of animal fats mixed with diesel and the main emissions produced. Hypodermic tissue is the one that contains fatty substances, they are eliminated during processing. The processing of high-fat skins necessarily implies its recovery. The animal skin is subjected to a very large number of chemical but also mechanical operations to be able to turn...
The topic of Particle Swarm Optimization (PSO) has recently gained popularity. Researchers has used it to solve difficulties related to job scheduling, evaluation of stock markets and association rule mining optimization. However, the PSO method often encounters the problem of getting trapped in the local optimum. Some researchers proposed a solution to over come that problem using combination of...
Bioelectrical impedance analysis (BIA) is one method of measuring body fat levels by distinguishing the fat mass and non-fat mass based on body composition assessment. This research designs a system to measure the body fat percentage by BIA method. The system is capable of measuring BIA with automatic switching between four different electrode schemes, i.e cross-sectional, hand-to-hand, hand-to-foot,...
Bufferless, deflection-routed, Butterfly Fat Trees (BFTs) can outperform state-of-the-art FPGAs overlay NoCs such as Hoplite by as much as 2–5× on throughput and ≈5× on worst-case latency at identical PE counts, and by ≈1.5× on throughput at identical resource costs >16K LUTs for statistical traffic patterns. In this paper, we show how to modify the tree connectivity and routing function to support...
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease and can often lead to fibrosis, cirrhosis, cancer and complete liver failure. Liver biopsy is the current standard of care to quantify hepatic steatosis but it comes with increased patient risk and only samples a small portion of the liver. Imaging approaches to assess NAFLD include proton density fat fraction...
There are two generally used ultrasonic approaches to extract sets of quantitative parameters: the Lizzi-Feleppa (LF) and quantitative ultrasound (QUS) approaches. The LF approach estimates LF parameters from the linear fit of the backscatter coefficient (BSC), and yields slope, intercept and midband. The QUS approach relies on the attenuation coefficient (AC) and BSC versus frequency, and yields...
The proposed paper deals with simulation and analysis of the radiofrequency field inside the multilayered human tissue model comprising a superficial metallic implant. The research was carried out using electromagnetic modeling based on the Finite Integration method and analysis was performed in terms of computing electric field distributions and spatial-averaged SAR distributions. The main objective...
Quantitative ultrasound parameter estimates from the Lizzi-Feleppa (LF slope, intercept and midband) and quantitative ultrasound (mean BSC, mean AC, ESD and EAC) approaches were compared for in vivo and ex vivo mouse liver fat content monitoring. The quantitative ultrasound parameters having the higher correlations with fat content were EAC (R2=0.68), mean BSC (R2=0.60), mean AC (R2=0.60) and LF midband...
Early detection and diagnosis of high-risk vulnerable plaques can reduce the death rate attributable to atherosclerosis. Many attempts to identify plaques have focused on in vivo imaging techniques. Animal models with foregone plaque sites will be valuable to evaluate the validity of the imaging methods. However, in traditional balloon injury models, the sites and size of generated plaques are uncertain...
Measurement of body fat distribution by using electrical impedance tomography (EIT) has been studied. We explored by simulation optimal number and arrangement of electrodes which optimize estimated accuracy and calculating time of image reconstruction and is suitable on practical use.
Early detection and diagnosis of high-risk or vulnerable plaques can reduce the death rate attributable to atherosclerosis. Many attempts to identify atherosclerosis plaques have focused on in vivo imaging techniques. An animal model with foregone plaque sites will be valuable to evaluate the validity of imaging method. Based on the “response-to-injury” hypothesis, lesions in the artery's endothelium...
Assessing the interventricular septum (IVS) facilitates the understanding of complex ventricular-ventricular interaction and related cardiac diseases. Previous studies have revealed that the functionally bilayered IVS exhibits distinct radial and circumferential strains in its left (Ls) and right (Rs) sides. Nonetheless, the transverse shear and principal strains, which reflect the interlayer sliding...
Traditional B-Scan images show the envelope of received echoes as a grey scale image. The echoes are produced from specular reflections and scattering sites where changes in acoustic impedance occur (Cobbold, Foundations of Biomedical Ultrasound, Oxford Press, 2007). A long-standing area of interest concerns the frequency dependence of scatterers within different tissues, organs, and the blood.

Individual handwriting is an important feature of a person, reflecting his personality, cultural and intellectual level. The possibility of using in the cyberspace a unique manner of writing the text, which is inherent in every person, promotes the strengthening of the personal principle, emphasizes the uniqueness of the individual. The article deals with the problem of constructing individual digital...
In this era of big data and internet of things, the need for performance improvement in cloud data center is unavoidable. This has led to several designs of data center network topologies with the aim of achieving a data center that has the capability of tolerating fault during multiple failures. In this paper, we proposed improved variants of fat-tree interconnections to mitigate the challenges of...
