Catheter Motion Tracking from Fluoroscopy Image Sequence
-
Tomislav Petković The topic of this master's thesis is real time guide wire tracking and 3D reconstruction. Guide wire and guiding catheter navigation is of utmost importance for successful endovascular interventions. Physicians usually use monoplane 2D medical imaging x-ray devices as navigational aids, however, such devices do not provide a real 3D position that is desireable for more accurate and shorter procedure. We use 2D monoplane x-ray imaging to track the guide wire. With the help of preoperatively...

Centralizirano upravljanje strukturalno promjenljivim sustavima s više vozila zasnovano na pridjeljivanju resursa
-
Tamara Petrović Područje istraživanja doktorske disertacije su centralizirane metode za koordinaciju u sustavima s više vozila kojima se sprečavaju zaglavljenja te kolizije između vozila i objekta u prostoru, uz ostvarivanje što veće protočnosti. Metode prikazane u disertaciji temeljene su na diskretizaciji okruženja na resurse, pri čemu kapacitet resursa označava broj vozila koja se istovremeno mogu na njemu nalaziti. Na ovaj način definiran je sustav za pridjeljivanje resursa te je...

Characterization of power inductor losses and electromagnetic emissions of fast switching synchronous converters.
-
Josip Bačmaga A presented methodology for frequency-domain characterization of two-port DC-biased components is based on combination of series and shunt method. The test structure based using a bias tee is designed to allow the S-parameter measurements of the inductive components under different DC current levels. A methodology for time-domain characterization of power inductor losses is designed to allow the precise estimation of the power losses caused by the triangular current waveform. The designed...

Circuit design of radio frequency identification system blocks in CMOS technology
-
Niko Bako Demand for RFID systems that are integrated with analogue-to-digital converters and wirelessly powered sensor nodes is constantly increasing. One of the main requirements for these systems is low-power consumption, which is typically in the range from hundred nW to few tens of µW. The standard circuits, such as e.g. bandgap references, can not be used and the designers must find new circuit architectures. The aim of this research is the design of several most used circuits, e.g. oscillator,...

Cjelobrojno programiranje pri nekim problemima raspoređivanja
-
Krešimir Križanović Problemi raspoređivanja javljaju se u organizaciji poslovanja u različitim poslovnim okruženjima. Jedna od metoda za rješavanje takvih problema jest cjelobrojno programiranje, tj. linearno programiranje kod kojeg se zahtijeva da su varijable cjelobrojne ili čak binarne. Web-servisi su opće prihvaćena tehnologija koja omogućava komunikaciju između različitih sustava. U organizaciji rada i nastave na Fakultetu elektrotehnike i računarstva mogu se uočiti razni problemi...

Classification and clustering of low back pain patients by analyzing surface myoelectric signals
-
Vedran Srhoj-Egekher Low back pain (LBP) is a global health problem phenomenon. Most patients are categorized as non-specific, thus requiring an individualized approach which still poses a major challenge. Myoelectric recordings from two pairs of lumbar muscle sites were collected during an isometric trunk extension exercise. Ninety-one subjects were included in the study; 29 patients with non-specific chronic LBP (CLBP), 25 patients with radiculopathy (RLBP), and 37 control healthy subjects (HS). Six...

Classification of cognitive load and emotional stress based on functional brain imaging techniques
-
Ivan Kesedžić Cognitive load and emotional stress affect people’s daily lives, so the adequate assessment of cognitive load and emotional stress is of special importance. Inadequate amounts of cognitive load and emotional stress negatively affect human performance and, in the long run, the health of the individual. Assessing cognitive load and emotional stress is especially important in highly stressful professions such as the military, pilots, and air traffic controllers.
Although cognitive load...

Clustering Maintenance Algorithms in Ad-Hoc Networks
-
Haris Hadžić This master thesis investigates clustering and cluster maintenance algorithms needed to solve problems connected to a lack of MANET (Mobile Ad Hoc Network) infrastructure and the continuously changing topology of a MANET. A goal was to develop, investigate and compare new as well as existing clustering algorithms. Four new algorithms, Cluster head centric maintenance, DSDV-based maintenance, Connectivity-based maintenance and Two-hop based maintenance, have been proposed, implemented and...

Cognitive radio networks optimization with spectrum sensing algorithms
-
Tanuja Satish Dhope Static allocation of spectrum scheme around the world, which is allocated to specific technology based services, such as mobile, fixed, broadcast, fixed satellite and mobile satellite services is commonly used on exclusive basis. These wireless communication systems are representatives of 2G and 3G systems with all evolution phases towards 4G systems. The complexity of wireless networks requires a careful design, especially related to bandwidth and energy efficiency. Bandwidth efficiency is...
