Over the years it was established that students waste the majority of their time in classes on adopting software interface which leaves them with very little time to master the key principles in the curriculum. This is especially true in the case of the embedded systems because there students must learn to work with several software packets. The developed software system allows students to concentrate on just one graphical interface which is intended to handle every aspect of embedded system design - from algorithm simulation to the hardware implementation. Apart from this the system is capable of communicating with the third party software without burdening the user with the new interface.

Intelligent medical systems are successfully applied at all 5 degrees of preserving health: the promotion of health, specific medical prevention, early diagnosis and therapy, sequel prevention and rehabilitation. In conditions of intensive changes and development, when the Serbian healthcare system is in the process of radical reorganization, especially in the present year of 2012, new challenges and needs are created for the implementation of newer, more modern intelligent systems on all the levels of health care. The present work is dealing with the analysis of benefits and challenges which are the result of applied and planned information systems in our country.

The processors and available memory in time has become smaller, faster, cheaper and power efficient. This development opened the way for the creation of the mobile devices with the graphical and sound interfaces in order to simplify and enhance the communication between the people and the machines. Additional adjustment to this hardware, primarily dictated by the software, led to the possibility of improving the methods and the speed in which the students absorb the new knowledge. The advantage of this approach lies in the fact that the anchor point in education was transferred from the mere observation of the lecture presentation to the active participation in the aggregation of the new material.

The laboratory measurements require physical presence of the student in the laboratory. When physical presence of the students is not possible the only way to perform the measurements is to alter the exercises to compensate for deficiency in equipment for remote access which results in separate exercises for distance education students. The purpose of this research was to find ways to integrate the distance education students into the laboratory for mechatronical measurements, without the physical presence or altering the laboratory exercise so regular and distance education students can attend to the same classes. The equipment is comprised of web cameras, National Instruments hardware and graphical user interface for remote access.

The Pre-Study on Education (Sabo, 2013) processes the theoretical foundations on which a framework was built. The study examines the possibilities of digitizing and implementing the existing framework in a virtual environment using the MaxWhere environment. After reviewing the environment, the virtual media and panels that may be suitable for DSP education had been selected. Testing selected display formats and simulation options is in progress with a small number of student groups. Successful integration of the digital filter design into a virtual environment is expected to make the adoption of the required material more effective for students.

Despite the initial refuse of their use due to informatical, economical, educational and other reasons, these systems are widely accepted in medical institutions operating in all levels of healthcare. The accuracy of some up-to-date neuro-fuzzy systems today matches or even surpasses the diagnostic abilities of physicians, thus holding an important role in risk-assessment and diagnostics in medicine. This work deals with newer applications of these systems in medicine along with the possibility of their implementation in the region of Central Europe. I. NEURO-FUZZY SYSTEMS IN MEDICAL

The device uses an ultrasonic sensor for measuring distance, which is later used for both navigation and obstacle detection. Data were used later to compose a matrixthe schematic map of the room. This map could be uploaded to the cloud for later use by other 3rd party devices so they do not have to redo the mapping process again.

When developing, one should not only pay attention to how noisy is the equipment itself, but also how immune it is to the noise coming from the surroundings. The purpose of this article is to present an instrument used in EMC measurement on a training model and then to evaluate the measured results according to the given standards. During the course of the test, a panel designed for training by Texas Instruments was used coupled with a measuring receiver and a GTEM cell. The obtained results clearly showed the advantages and disadvantages of the cell construction compared to other EMC measurement procedures.

However, due to the dangers and complications of liver biopsy, there is a worldwide demand for the development of non-invasive procedures that can accurately determine the degree of hepatic steatosis, furthermore is cost-effective, user-friendly, and provides repeatable measurement. Based on the metrological experience of our research team, we started developing an electrical impedance-based diagnostic method a few years ago that meets these requirements and is suitable for early detection of nonalcoholic fatty liver disease (NAFLD) with the help of a worldnew measurement and data collection solution. In addition to the preliminar results of the long-term clinical validation of the diagnostic method developed to detect NAFLD, the authors present early partial results. Even with the small amount of data, very impressive results have been obtained.
Development of Bioimpedance-based Measuring Systems for Diagnosis of Non-alcoholic Fatty Liver Disease

The prevalence of the disease is estimated as high as 25% of the general population up to 90% of obese and diabetic patients. Most patients are asymptomatic or does not experience specific complaints making them difficult to diagnose and treat. However, due to the limitations of available diagnostic procedures and the current gold standard for diagnosis, the liver biopsy, there is a worldwide demand to develop a non-invasive diagnostic tool and procedure that can detect the disease with high accuracy at an early reversible stage, furthermore is cost-effective, user-friendly, and provides repeatable measurement. Based on the metrological experience of our research team, we started developing an electrical impedance-based diagnostic procedure a few years ago that meets these requirements and is suitable for early detection of NAFLD with the help of a world-new measurement and data collection solution. In this article, we present the most important milestones in the development of instruments related to research.

For this purpose the description DSL (Domain Specic Language) language was used. The goal of this paper is to dene and present a high level language that allows description and development of signal processing algorithms. With the usage of a domain specic language, one can create a compact and easy to understand denition of algorithms. In the paper the authors present the advantages granted by DSL for DSP applications. The created denitions are hardware independent and they can be executed and functionally veried. Ecient code can be generated for various targets without porting. The design of the presented DSL allows code generation for multi-core targets in case of computing-intensive algorithms, code generation for multiple streams and threads. To validate the results these blocks were made available for use to students as an easy method for the introduction of t...

This paper describes a protocol converter which is part of a measurement acquisition system for multichannel real time recording of brain signals. In practice, in such techniques, a primary consideration of reliability leads to great necessity towards increasing the sampling rate of these signals while simultaneously increasing the resolution of A/D conversion to 24 bits or even to the unprecedented 32 bits per sample. In fact, this was the guiding principle for our team in the present study. By increasing the temporal and amplitude resolution, it is supposed that we get enabled to discover or recognize and identify new signal components which have previously been masked at a “low” temporal and amplitude resolution, and these new signal components, in the future, are likely to contribute to a deeper understanding of the workings of the brain.
