In this paper we present a review of gait analysis methods used for medical applications. First of all, we introduce a system of real-time gait acquisition. Next, three ways of gait data representation: trajectories, Euler angles and medical angles are described along with the most promising methods of gait analysis based on those representations like gait indices, Dynamic Time Warping, manifold methods...
Minimizing the level of harmful factors in the workplace is one of the basic tasks in maintaining industrial safety, including health care and work comfort. In this view systematic monitoring of harmful factors level by performing reliable measurements in the workplace is crucial. The method of measuring electromagnetic field (PEM) levels in the workplace of particular machines and devices is standardized...
Through the lifetime, a person might stumble upon diseases many of which may be deadly. In order to save the person's life, doctors will prescribe many medicines that may help cure the person. To make stuff easier technology has introduced many new ways to facilitate the struggle that the person may undergo. One of the new ways introduced is an application that makes it easier for cancer and heart...
In this paper, a new and novel printed structure is proposed to obtain high quality factor (Q-factor) coil antenna in wireless power transmission system. The main idea to achieve high quality factor is “adjusted line pitch and width” with respect to outer diameters. The line pitch and width of the printed pattern are gradually increased in proportion with outer diameter. By using this design method,...
Nowadays, the number of divers who want to practice the activity at technical level grows more and more. The Rebreather apparatus can be used to carry out such an experience. This underwater breathing equipment seems to be a complex system, but it is based on a very simple concept: the reuse of the exhaled gas. This apparatus is controlled by an electronic system, a specialized dive computer, that...
Electric cars in the worldwide vehicle stock have reached sizeable growth since 2010. Besides proven benefits to the sustainable development and wheel-to-wheel efficiency, electric cars can provide side benefits to car owners and to power system utility. Plug-in vehicles can behave either as loads or as a distributed energy and power resource in a concept known as vehicle-to-grid (V2G). This paper...
In this paper, after a brief introduction on the developed plug-and-play (PnP) process monitoring and control architecture, a decentralized plug-and-play (PnP) process monitoring system for large-scale industrial processes is studied. And then, aiming at lower online computational load and more flexible industrial implementation, a decentralized adaptive configuration technique is further developed...
Recently, FPGA-based NCS applications have been widely used. Industrial environments have a lot of electromagnetic interference which may induce transient and permanent faults. As a result, Fault-Tolerant FPGA based NCS applications are required. In this paper, an NCS model composed of a combination of S2A architecture and In-Loop architecture connected to each other through Ethernet switch, is described...
Device to device(D2D) communication exploits the proximity between mobile devices to allow direct communication. Doing so offers advantages which include less energy consumption, hop gain, reduced load on the base station among others. For instances where the channel between the D2D devices does not allow for efficient direct communication, a suitably selected idle mobile device can act as a relay...
Direct phase or indirect frequency control methods are used in series-resonant bridge power inverters for induction heating to maintain maximum power transfer as the load equivalent electrical parameters change during the heating process. In these applications, to control the power level it is common to use the above resonance operating frequency, where only measurement of the deviation of the phase...
Urban metro system consumes huge amount of electrical energy. Therefore, energy consumption, operating costs, and environmental impact of metropolitan transportation should be kept under the control. Capacity expansion and operation costs of urban rail systems are brought forward energy efficiency improvements in the urban rail transportation. Accordingly, there is urgent need to use renewable energy...
Rounding error in the discrete Fourier transform calculated with fast fixed-point algorithms is considered. It is shown that the variance of the rounding error depends on frequency index. Theoretically obtained results for error variance are statistically checked on decimation-in-time fast Fourier transform with two rounding methods.
This paper proposes an efficient algorithm for noise level estimation in still images. The images are assumed to be corrupted by additive white Gaussian noise. The proposed method relies on block-based image segmentation and Gaussian filtering to estimate the standard deviation of Gaussian noise. The proposed method employs adaptive image segmentation, where the size of segmentation blocks is derived...
Accurate and robust state estimation is a fundamental problem in signal processing. Particle filter is an effective tool to solve the filtering problem in nonlinear stochastic dynamic systems. However, when the system is mean-field dependent and the data is high-dimensional in spatial and temporal domain, the estimator may become inaccurate or even diverge. In this paper, we propose a Correlative...
Iris recognition is a biometric authentication system proving vital for ensuring security and has been employed as an important case to test the algorithms developed in pattern recognition. The unique circular shape of the iris and its time invariance makes it a versatile technique that has an accuracy that can be mathematically proven. Here in this work we propose a new segmentation technique and...
With the recent developments in medicine and biology experiments a large amount of data is gathered in the form of multimedia elements (images, videos). Many algorithms have been developed and adapted based on the system of interest, and often the most challenging feature of the images may be used to facilitate a better analysis of the image. Herein, we developed an image analysis algorithm for quantification...
This paper presents an advanced Security QoS provisioning module with vertical multi-homing and multi-streaming framework for 5G mobile terminals with radio network aggregation capability in next generation mobile and wireless broadband networks. The proposed mobile terminal framework is leading to high performance opportunities for multimedia services with high level of QoS provisioning and secure...
Security and privacy challenges are the most important obstacles for the advancement of IT-based on-demand services and cloud computing as an emerging technology. To ensure data confidentiality and fine-grained access control in cloud-based environments, stored data and resources needs to be re-encrypted periodically or based on special mechanisms such as revoked user-based or manual re-encryption...
