The paper proposes a novel method for extraction of blood vessels and veins from medical image of human eye - retinal fundus images that can be used in ophthalmology for detecting various eyes' diseases such glaucoma, diabetic retinopathy or macula oedema. The method utilizes an approach of preprocessing of image by using adaptive histogram equalization by CLAHE algorithm of green channel of fundus retinal image. Subsequently, using adaptive filters and image convolution with filter mask as key point of proposed algorithm and subsequently is applied the operation erosion processed image and removed small segments from image to enhance extraction of blood vessels from fundus image. The proposed technique analyzes detection and evaluates precision of the method on dataset from public fundus image libraries DRIVE, and HRF and compare with reference training results provided by these libraries..

Instrumentation amplifiers (IA) used in wearable biomedical monitoring systems have to satisfy several performance requirements, such as low-voltage supply and low-power consumption, enabling increased portability. In the same time, a very important feature is wide range parameter programmability. This paper proposes a solution to implement electronic gain programming into an IA. The proposed solution is developed around the current balancing concept. An electronically tunable transconductance amplifier is used for adjusting the IA voltage gain as a function of the transconductor bias currents. Additionally, the proposed IA outputs a differential signal, useful for latter differential analog signal processing. Simulation results validate the proposed IA.

This paper presents a novel human ear recognition approach based on Multi-scale Local Binary Pattern (MLBP) descriptor to enhance the recognition performance. The proposed method includes the following two steps: (i) the feature extraction step that computes the MLBP descriptor-based features from human ear images, and (ii) the matching process that uses the Kullback Leibler (KL) distance to capture efficiently the similarities/dissimilarities between the feature vectors and then make a decision. The proposed method is performed using the IIT Delhi Ear database and then compared to the state-of-the-art methods. The results obtained have shown that the proposed method achieves satisfying identification performances up to 95% in terms of rank-1 identification rate.

The aggressive expansion of emerging smart devices connected to the Internet infrastructure is nowadays considered as one of the most challenging components of the Internet of Things (IoT) vision. As a particular segment of IoT, the smart home gateways, also named Machine-Type Communication Gateway (MTCG), become an important direction for industry including telecommunication operators. In most cases, the MTCG acts as a bridge between connected smart objects and the public network (Internet). As a consequence of the IoT domain expansion, the separate configuration of each individual Machine-to-Machine (M2M) device is not feasible anymore due to steadily growing numbers of M2M nodes. To perform this task, several novel technologies have recently been introduced. However, legacy protocols and mechanisms for remote network management still retain a certain application potential for IoT. Accordingly, we have investigated the well-known protocol TR-069 with a particular focus on its usability for MTCG. To this end, the software module (bundle) based on the TR-069 for remote configuration and management of MTCG, as well as for controlling the end smart devices, has been developed. We believe that our implementation (available as open source on GitHub) can serve as an important building block for efficient management of future IoT devices. Therefore, TR-069 protocol constitutes a proven and standardized technology and could be easily deployed by most of the network and service providers today.

Fractional-order filter design examples, realized through the substitution of fractional-order capacitors and inductors by appropriate active emulators, are presented in this paper. The implementation of emulators has been achieved using Current Feedback Operational Amplifiers (CFOAs) as active element. Also, the realization of the required fractional-order differentiation/integration, for emulating the fractional-order elements, is performed through the employment of an integer-order multi-feedback topology. An important benefit, from the design flexibility point of view, is that the same topology could be used for emulating both fractional-order capacitor and inductor, and this is achieved through an appropriate selection of the time-constants and gain factors. The behavior of the realized filters is evaluated using the commercially available AD844 discrete CFOA.

In this paper, a new active-only integrator which can be used to realize low frequency filters with small chip area is presented. The circuit can be effectively implemented using transconductance elements and its integration frequency is electronically controllable. In order to illustrate its usefulness, a second-order multifunction filter with low cut-off frequency, yet which occupy a small chip area is presented. Simulation results of the filter using SPECTRE in the CADENCE design tool which verify its proper operation are provided.

Over the last decades Ultra-Wideband (UWB) radio communication has gathered an increasing interest in the research community, due to its unique features resulting out of large bandwidth like the capability for precise localization. Nevertheless in dense indoor environments, multi-path propagation often leads to unpredictable errors in the time-of-flight based ranging process, leading to unreliable range measurements. In this paper, we present measurements within different environments and discuss the effects during the ranging process that lead to incorrect measurements. As the key contribution of our paper we present a method of gaining a quality measure for obtained range measurements, which enables to filter out erroneous measurements. In addition, we show first results applying this approach.
