AB  - In order to further investigate performance of Optomagnetic Imaging Spectroscopy in cervical cancer detection, deep learning algorithm has been used for classification of optomagnetic spectra of the samples. Optomagnetic spectra reflect cell properties and based on those properties it is possible to differ-entiate normal cells from cells showing different levels of dysplasia and cancer cells. In one of the previous research, Optomagnetic imaging spectroscopy has demonstrated high percentages of accuracy, sensitivity and specificity in cervical cancer detection, particularly in the case of binary classification. Somewhat lower accuracy percentages were obtained in the case of four class classification. Compared to the results obtained by conventional machine learning classification algorithms, proposed deep learning algorithm achieves similar accuracy results (80%), greater sensitivity (83.3%), and comparable specificity percentages (78%).

AB  - This paper presents a new optimisation method for PID controller cascaded with a lead-lag compensator (PIDC). Parameters of the controller are obtained by solving the constrained optimisation problem. We propose two variants of the optimality criterion. The first one is defined through the max-min optimisation problem wherein objective function is the amplitude frequency response of the PIDC controller. The second one is based on an effective approximation of the minimum value of the amplitude frequency response of the PIDC controller. Consequently, we obtain a computationally less expensive problem. Both variants of optimality criterion result in efficient load disturbance and noise rejection, while robustness is ensured by constraining the value of the maximum sensitivity Ms. Good reference shaping is supported with proper constraints based on the Amplitude Optimum (AO) principle. Numerous batches of processes typically encountered in the industry are used to demonstrate the effectiveness of the proposed design method.

AB  - Ispitivanje uticaja svetlosti, kako prirodne tako i veštačke, od izuzetne je važnosti sa aspekta zdravlja očnog aparata i funkcionisanja ljudskog organizma generalno. Očne strukture poseduju različit stepen osetljivosti na dejstvo elektromagnetnog zračenja, tako da neke talasne dužine mogu prouzrokovati fotohemijska i fototermalna oštećenja. Zračenje u domenu ultraljubičastog (UV) i visoko-energetskog plavog svetla predstavlja izuzetnu pretnju očnim tkivima, uz istovremen uticaj i na moždane funkcije. Istraživanje novih materijala koji će biti u mogućnosti da filtriraju i potpuno eliminišu ili transformišu štetne talasne dužine zračenja je od savremenog javnog značaja. Novi optički materijali treba da poseduju sposobnost podešavanja i preciznog definisanja karakteristika talasnih dužina transmitovanog zračenja. Mnogi fotofizički i fotohemijski procesi upravo zavise od izbora talasne dužine tako da optički filteri, sa različitim transmisionim karakteristikama, omogućavaju fotostimulaciju istih i kao takvi potomažu razvoju novih fotonskih uređaja, fototerapijskih aparata i zaštitinih pomagala. Uočeno je da prilikom zatamnjenja optičkih pomagala, stavljanja blokatora za UV i plavu svetlost, nisu zadovoljeni kriterijumi osetljivosti oka pa dolazi do pojave neželjenih efekata, čije dejstvo izaziva naprezanje očnih struktura, a zatim i njihovo oštećenje. Saglasno tome, osnovni cilj ove doktorske disertacije je iznalaženje optičkog pomagala koje će sprečiti štetan uticaj UV i visoko-energetskog plavog svetla, uz transformaciju upadnog spektara svetlosti tako da bude što bliži spektru osetljivosti oka. U svrhu realizacije postavljenih ciljeva istraživanja, za izradu optičkog pomagala korišćeni su nanokompozitni materijali na bazi polimera (poli (metil metakrilata), PMMA) i nanomaterijala, fulerena (C60). Nanokompozitni materijali izrađeni su sa četiri koncentracije nanomaterijala (0.025mas%, 0.050mas%, 0.075mas% i 0.100mas%.). Za ispitivanje optičkih karakteristika nanokompozitnih materijala korišćeni su UV/VIS spektrofotometar (ILT350 Spectroradiometer, International Light Technologies, SAD), UV/VIS/NIR spektrometri (Lambda 950, Perkin Elmer, Italija i C10082CA, Mini-spectrometer, Hamamatsu, Japan) i FTIR mikrospektroskopski sistem (Spotlight 400 FT-IR Imaging System, Perkin Elmer, Italija). Za nanokarakterizaciju novih materijala korišćen je uređaj za mikroskopiju atomskih i magnetnih sila (JSPM 5200, JEOL, Japan). Istraživanjem su definisane razlike difuzne svetlosti koja ulazi u sistem optičkog pomagala i izlazne svetlosti iz optičkog pomagala. Multifaktorska analiza snimljenih karakteristika nanokompozitnih materijala za optička pomagala, spektroskopskim i nanotehnološkim metodama i tehnikama, ukazuje na značaj koncentracije molekula S60 u nanokompozitnom materijalu, odnosno uticaju njegove koncentracije na optička i strukturna svojstva novodobijenog materijala. Eksperimentalno je utvrđeno koja od navedene četiri koncentracije najviše pogoduje izradi optičkog pomagala. Probna sočiva, sa adekvatnom koncentracijom nanomaterijala, testirana su u okviru preliminarne oftalmološke studije, u dve oftalmološke ordinacije, Laserfocus i Macula, iz Beograda.

AB  - We aimed to assess the near infrared spectroscopy as a method for non-invasive on-line detection of hyperglycemia from spent hemodialysis effluent. We used partial least squares regression and several machine learning algorithms: random forest (RF), logistic regression, K-nearest neighbor (KNN), support vector machine (SVM), decision tree classifier, and Gaussian naive Bayes (NB) to classify normoglycemia from hyperglycemia. These classifier methods were used on the same dataset and evaluated by the area under the curve. The serum glucose levels were presented in the form of a binomial variable, where 0 indicated a glucose level within reference range and 1 a glucose level beyond the normal limit. For this reason, the methods of machine learning were applied as more specific methods of classification. RF and SVM have shown the best classification accuracy in predicting hyperglycemia, while decision tree and NB showed average accuracy.

AB  - Anemia is commonly present in hemodialysis (HD) patients and significantly affects their survival and quality of life. NIR spectroscopy and machine learning were used as a method to detect anemia in hemodialysis patients. The aim of this investigation has been to evaluate the near-infrared spectroscopy (NIRS) as a method for non-invasive on-line detection of anemia parameters from HD effluent by assessing the correlation between the spectrum of spent dialysate in the wavelength range of 700-1700 nm and the levels of hemoglobin (Hb), red blood cells (RBC), hematocrit (Hct), iron (Fe), total iron binding capacity (TIBC), ferritin (FER), mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) in patient blood. The obtained correlation coefficient (R) for RBC was 0.93, for Hb 0.92, for Fe 0.94, for TIBC 0.96, for FER 0.91, for Hct 0.94, for MCV 0.92, for MCHC 0.92 and for MCH 0.93. The observed high correlations between the NIR spectrum of the dialysate fluid and the levels of the studied variables support the use of NIRS as a promising method for on-line monitoring of anemia and iron saturation parameters in HD patients.

AB  - Recently, calculus of general order alpha is an element of R has attracted attention in scientific literature, where fractional operators are often used for control issues and the modeling of the dynamics of complex systems. In this work, some attention will be devoted to the problem of viscous friction in robotic joints. The calculus of general order and the calculus of variations are utilized for the modeling of viscous friction which is extended to the fractional derivative of the angular displacement. In addition, to solve the output tracking problem of a robotic manipulator with three DOFs with revolute joints in the presence of model uncertainties, robust advanced iterative learning control (AILC) is introduced. First, a feedback linearization procedure of a nonlinear robotic system is applied. Then, the proposed intelligent feedforward-feedback AILC algorithm is introduced. The convergence of the proposed AILC scheme is established in the time domain in detail. Finally, simulations on the given robotic arm system confirm the effectiveness of the robust AILC method.

AB  - Development of 3D printing in medical and dental applications has advanced significantly in recent years. 3D technologies are commercially available, i.e. 3D printing and 3D scanning, allowing dentists to easily scan and record state of hard and soft tissues following 3D printing of dental models or supporting structures-like surgical guides and aligners. Thereafter, dental technicians work with these 3D printed dental models of upper and lower jaw, as they previously have been working with plaster models, and because of attainable high dimensional accuracy of these dental models 3D printing technology found its way in dentistry and will improve both in today’s application and will expand the range of possible applications in dentistry. The aim of this paper is to present stereolithography (SLA) 3D printing technology of dental working models. SLA technology is mainly applied in rapid prototyping, but due to exceptional dimensional accuracy it easily found its application in dentistry, where accuracy is of utmost importance. SLA technology works in layer-by-layer manner, using UV lasers to polymerize, i.e. solidify, liquid photopolymer resin placed in a vat. Only accuracy issue of this technology occurs when using more layers to build a model, i.e. if an error appears at a certain layer it will stack on succeeding layers and will create notable dimensional mismatch. Materials used in this research are grey standard resin, dental model resin, long-term biocompatible clear resin and biocompatible photopolymer resin. Created dental models are used for planning and making dental crowns and bridges.

AB  - Considering the fertilization process as an oscillatory phenomenon, based on mechanotransduction theory of sperm–oocyte interaction, influence of sperm velocity and their specific arrangement on outer surface of oocyte- Zona pellucida (ZP) relative to the oscillatory behavior of ZP was studied using discrete continuum oscillatory spherical net model of mouse ZP. For the calculated favorable impact angles of spermatozoa by using generalized Lissajous
curves, a parametric frequency analysis of oscillatory behavior of the knot molecules in the mouse ZP spherical net model is conducted. In order to mimic successful fertilization in physiological conditions in this numerical experiment, velocities of the progressive and hyperactivated spermatozoa were used. The resultant trajectories of knot molecules in mouse ZP (mZP) spherical net model,in the form of generalized Lissajous curves, are presented. Influences of the
sperm velocity and its arrangement on the resultant trajectory of the corresponding
knot molecules are discussed. Component displacements in the meridian and circular directions of the knot molecules of ZP are in the form of multi-frequency oscillations. Symmetrical arrangements of spermatozoa having effective velocities are more favorable for achieving a favorable oscillatory
multi-frequency state of mZP for a successful fertilization. Determining the optimal parameters of spermatozoa impact that will induce a ZP favorable oscillatory state opens the possibilities for more complete explanation of the fertilization process.

AB  - Semi-automated system for classification of cervical smear images based on Optomagnetic Imaging Spectroscopy (OMIS) and machine learning is proposed. Optomagnetic Imaging Spectroscopy has been applied to screen 700 cervical samples prepared according to Liquid Based Cytology (LBC) principles and to record spectra of the samples. Peak intensities and peak shift frequencies from the spectra have been used as features in classification models. Several machine learning algorithms have been tested and results of classification have been compared. Results suggest that the presented approach can be used to improve standard LBC screening tests for cervical cancer detection. Developed system enables detection of pre-cancerous and cancerous states with sensitivity of 79% and specificity of 83% along with AUC (ROC) of 88% and could be used as an improved alternative procedure for cervical cancer screening. Moreover, this can be achieved via portable apparatus and with immediately available results.

AB  - Jedna od najperspektivnijih tehnika za ispitivanje sastava, strukture i svojstava materijala je mikroskopija sondama za skeniranje (SPM), odnosno njene komponente mikroskopija tunelovanjem elektrona (STM) i mikroskopija atomskim silama (AFM). Ovim metodama se rutinski postiže nanometarska i atomska rezolucija. Posebno istaknuta prednost metode je da ne postoje ograničenja u smislu porekla i sastava uzoraka, te je moguće ispitivanje organskih i neorganskih materijala. Ova tehnika se primenjuje u savremenim multidisciplinarnim istraživanjima u oblasti medicine, farmacije, stomatologije, nauke o materijalima, itd, i to za ispitivanje bioloških uzoraka, hemijskih jedinjenja, farmaceutskih proizvoda, veštačkih tkiva, materijala za implantologiju, i svih ostalih materijala čija nanotehnološka svojstva imaju uticaj na primenu u navedenim naučnim oblastima. Međutim, snimci dobijeni pomoću AFM-a su samo aproksimacije površina uzoraka, jer sonde nemaju ni savršenu veličinu ni geometriju, usled čega dolazi do pojave artefakata koji se definišu kao karakteristike koje se pojavljuju na snimku a koje nisu prisutne na ispitivanom uzorku. Ovi efekti izazvani konvolucijom između sonde i uzorka mogu do izvesne mere da budu korigovani matematičkom manipulacijom topografskim podacima. Metodologija koja je u ovom radu korišćena se zasniva na algebri skupova i osnovnim alatima matematičke morfologije. Iskorišćeni su matematički algoritmi za “slepu rekonstrukciju” vrhova sondi, a potom je izvršena dekonvolucija, da bi se otkrili delovi površine uzorka koji u realnosti nisu bili dostupni. Granica realnog vrha sonde se izračunava iz slike pomoću morfoloških ograničenja koja su inherentna u procesu snimanja. Rezultat se dobija u vidu snimka rekonstruisane površine uzorka iz dobijenih snimaka, uz pomoć rekonstrukcije vrha sonde kojom je uzorak sniman.
AB  - One of the most perspective available technique for investigation of the composition, structure and properties of materials, is scanning probe microscopy (SPM), respectively its components scanning tunneling microscopy (STM) and atomic force microscopy (AFM). The advantage of the method is that they have no restrictions related to origin and composition of the material, and its possibilities to investigate vide variety of materials. This technique is used in multidisciplinary research in the field of medicine, pharmacy, dentistry, material science, etc., for study of biological samples, chemical compounds, pharmaceutical products, artificial tissues, implantology materials, and all other materials that have nanotechnological impact on application in these scientific fields. However, images obtained by AFM represent only approximation of the sample surfaces. This is because the probes have not perfect size and geometry, which leads to the appearance of artifacts. They are defined as characteristics that appear on the image and are not present on the sample. These effects caused by convolutions between the probe and sample can be corrected to a certain extent by mathematical manipulation of topographic data. The methodology used in this paper is based on algebra of sets, and basic tools of mathematical morphology. Mathematical algorithms for the "blind reconstruction" of the tip were used, and then in order to detect the parts of the sample surface which is not available in real-time scanning deconvolution was applied. The limit of the real probe tip is calculated from the image, using the morphological limitations inherent in the recording process. The result acuired as an image of the reconstructed surface out of the used images, with the reconstruction of the real tip.

AB  - The investigation into the dynamics and control of robotic and complex (bio)mechanical
systems has been an active topic of research for many years. The science of
robotics/adaptronics has grown tremendously over the past twenty years, fueled by rapid
advances in computer and sensor technology, as well as theoretical advances in control
theory. Recently, calculus of general order R has attracted an increased attention of
scientific society where fractional operators are often used for control issues and for
modelling dynamic of complex systems,[1].The modelling complex rigid multibody systems
using symbolic equations can provide many advantages over the more widely-used numerical
methods of modelling these systems.
In this presentation, we propose using procedure for symbolic form computation of the
complete dynamics of (exoskeleton) robotic systems with kinematic chain structures using the
Rodriquez approach, [2]. Dynamic equations are given as Lagrange equations of the second
kind in the covariant form with external generalized forces of the gravity, motor-torque,
viscous and spring. Mathematical model of the proposed NeuroArm robotic system due to a
high gear ratio between the actuators and robot joints, can be reduced to a linear model.
Robust control of general order with no overshoot can be obtained using fractional order
compensator which is designed according to the symmetrical optimum principle, [3].The
effectiveness of the proposed method will be illustrated through the control simulation of
three degrees of freedom robot manipulator. Also, some attention will be devoted to problem
the viscous friction in robotic joints. The calculus of general order and the calculus of
variations are utilized to modelling the viscous friction which is extended to the fractional
derivative of the angular displacement. This model is introduced into dynamic equations via
generalized forces which are derived by using the principle of virtual work.
Also, it is presented the tracking problem of exoskeleton robotic system for rehabilitation
with three DOFs with revolute joints via intelligent control which includes advanced iterative
learning control (ILC), [4]. First, a feedback linearization control technique based on
computed torque method is applied on a given robotic system. Then, the proposed intelligent
ILC algorithm takes the advantages offered by closed-loop control PD type and open-loop
control sgnPDD2 type of ILC. Suggested robust ILC algorithm is applied to the linearized
system to further enhance tracking performance for repetitive tasks and deal with the model
uncertainties. Finally, a simulation example is presented to illustrate the effectiveness of the
proposed robust ILC scheme for a proposed exoskeleton robot arm.

AB  - The paper designs an appropriate iterative learning control(ILC) algorithm based on the trajectory characteristics of upper exoskeleton robotic system.The procedure of mathematical modelling of an exoskeleton system for rehabilitation is given and synthesis of a control law with two loops. First (inner) loop represents exact linearization of a given system, and the second (outer) loop is synthesis of a iterative learning control law which consists of two loops, open and closed loop. In open loop ILC sgnPDD2 is applied, while in feedback classical PD control law is used. Finally, a simulation example is presented to illustrate the feasibility and effectiveness of the proposed advanced open-closed iterative learning control scheme.

AB  - In this paper we have analyzed the standard linear solid model (Zener model) of viscoelastic
materials. A one-dimensional analysis was executed analytically (in MATLAB) and numerically
(in ABAQUS), and corresponding graphs have been produced. The fractional differential form of
the Zener model was then implemented, as it has proven to be a better match for the experimental
test results for viscoelastic materials. Finally, all of the results were compared and discussed.

AB  - Colorectal carcinoma (CRC) as a major health problem in industrialized countries is highly preventable and can be successfully treated in the early stages. However, incidence and mortality of CRC has increased over the last two decades. The reason could be that the current recommended options for screening are costly, unpleasant for patients, have low sensitivity and poor accessibility for screening. These reasons provide a strong rationale for the development of a new method. Opto-magnetic imaging spectroscopy (OMIS) as a new imaging method for the characterisation of various materials, including human tissues, is based on light-matter interaction, using a Poincare sphere for light properties and a Bloch sphere for electron properties, and allows the detection of biophysical characteristics within human tissue samples. Compared with histopathology examination, the OMIS method achieved an accuracy of 92.59% using Multilayer Perceptron Neural Network as a classifier, and 89.87% using Naive-Bayes, respectively. The obtained results, based on the investigation of 316 samples, both tumour and normal mucosa (162 cancer cases), strongly suggest that the new non-invasive OMIS method might be used for tissue characterization ex vivo to discriminate between the healthy and carcinoma state of the colon. However, it opens up the possibility of using the same method in in vivo studies to assist physicians in targeting biopsies of colorectal tissue.

Papanicolaou smears and liquid based cytology samples were analysed in previous studies on cervical cancer detection by Optomagnetic Imaging Spectroscopy and it was shown that this method can diferentiate normal healthy tissue from the cancer tissue. So far, only binary classification of the cervical samples was performed based on optomagnetic spectra of the samples.

AB  - Dental-implant overload can cause bone resorption. Load-transfer characteristics of dental implants are affected by their macro-design parameters. The goal of this study was to experimentally analyse the load-transfer characteristics of different dental implants, using polymethyl-methacrylate blocks. Three polymethyl-methacrylate blocks were created, with dimensions of (68 x 25 x 9) mm. Three dental implants, Nobel empty set3.5 mm x 15 mm, Strauman empty set4.1 mm x 10 mm and Strauman empty set4.8 mm x 12 mm. were placed in separate blocks. The samples were supported by a three-point-bending set-up and loaded with an axial force of 600 N. The 3D digital image correlation method was employed for strain and displacement measurements. The highest displacement and von Mises strain values were found for Strauman empty set4.1 mm x 10 mm (p  lt  0.05), 0.186 mm and 0.596 %, respectively. The sample of Nobel empty set3.5 mm x 15 mm showed the lowest strain values. The sample of Strauman empty set4.8 mm x 12 mm (p > 0.05) had similar strain values as Nobel empty set3.5 mm x 15 mm. The load transfer during axial loading was primarily affected by the size of the implant contact surface. The displacement and strain values in the implant vicinity may provide an insight into the effect of dental-implant design on the load transfer.

AB  - In this communication, we propose a nonlocal fractional viscoelastic model of a nanobeam resting on the fractional viscoelastic foundation and under the influence of the longitudinal magnetic field and arbitrary number of attached nanoparticles. Size effects are taken into account using the differential form of the nonlocal constitutive relation together with the fractional Kelvin-Voigt model. The governing equation for the free vibration of a nanobeam is derived, where Maxwell's equations are used in order to represent the effect of the longitudinal magnetic field. We propose an analytical solution of the problem based on the Laplace transform, Mellin-Fourier transforms, and residue theory. From the validation study, it is shown that the obtained complex roots of the characteristic equation, where the imaginary part is the damped frequency and the real part is the damping ratio, are approximated eigenvalues of the system. In the parametric study, several numerical examples are given to investigate the influence of different parameters on complex roots as well as different masses and numbers of nanoparticles on the damped vibration behavior of a nanobeam system.

AB  - This paper presents simple, flexible and effective approximation method for fractional order lead-lag compensators. The proposed method relies on a Pade approximation of linear fractional order transfer functions, giving rational approximations of order N accurate enough for control applications as soon as N is greater than 2 or 3. An example of feedback loop incorporating this approximation is adopted from the well-known car suspension problem, wherein an iso-damping property of the closed loop response is achieved, with regard to a variation of the vehicle mass.

AB  - Background Sensitivity and specificity of ex vivo dermatoscopy ( EVD) for malignancy detection of skin tumors is unknown. We sought to assess whether the use of EVD could be a useful adjunct to histopathological diagnosis of pigmented skin tumors, including cases where complete clinical information is inadequate or missing. Materials and methods EVD was performed on 195 excised, formalin- fixed pigmented skin tumors. Results Of 183 eligible lesions, 104 ( 56.8%) were melanocytic and 79 ( 43.2%) nonmelanocytic. Overall, 54 ( 29.5%) were malignant: 10 melanomas, 39 basal cell carcinomas, and five squamous cell carcinomas. Ex vivo images were devoid of red color. The following colors were seen: light and dark brown, grey, blue, black, and white. All structures typical for pigmented melanocytic and nonmelanocytic lesions were observed. In malignant nonmelanocytic lesions, diagnostic accuracy and sensitivity for malignant/ benign decision was not better when combining visual assessment and EVD but diagnostic specificity improved by 3.0%. For melanoma, combined diagnostics improved diagnostic accuracy, sensitivity, and specificity for 9.6, 30.0, and 7.5%, respectively. Conclusion For dermatopathologists, EVD offers increased specificity for all categories of tumors and increased diagnostic accuracy, sensitivity, and specificity for melanoma. With EVD view, the dermatopathologist can instantly find areas of interest, thus minimizing the possibility for missing a malignant lesion.

AB  - Dizajn dentalnih implanata utiče na vrednosti deformacija koje nastaju u njihovoj okolini, i ako se pređe granična vrednost od 0.3 %, može doći do resorpcije kosti. Cilj ove studije je da predstavi novi eksperimentalni pristup za analizu uticaja geometrije dentalnih implanata na deformacije okolne strukture. Model kosti, sa dimenzijama od 68h25h9 mm, je napravljen od polimetil-metakrilata. Kalup za model koji je napravljen pomoću tehnike 3D štampe, je takođe služio i kao fiksator položaja za vertikalno postavljeni implant Štrauman ø4.0x12 mm. Uzorak je opterećen na savijanje u tri tačke. Aksijalna sila od 600 N je primenjena na dentalni implant. Za merenje deformacija i pomeraja je korišćena metoda Digitalne korelacije slika. Najveće vrednosti Von Mizesovih deformacija od 0.7 % su izmerene u području vrata implanta. Maksimalne vrednosti pomeraja u pravcu opterećenja su iznosile 0.466 mm. Površinska deformacija i pomeraji su povezani sa geometrijom implanata. Ova eksperimentalna metodologija se može koristiti u cilju određivanja karakteristika prenosa opterećenja dentalnih.

AB  - Savremeni dijagnostički testovi koji se koriste u kliničkoj praksi imaju neosporan uticaj na smanjenje smrtnosti kao posledice obolevanja od različitih tipova kancera. S obzirom da više od 85% kancera potiče iz epitelnog tkiva, za istraživanje u okviru ove doktorske disertacije je izabran grlić materice kao jedan od predstavnika epitelnih tkiva. Kada govorimo o kanceru grlića materice, Papanikolau test još uvek predstavlja nezamenljiv skrining test čiji se uticaj u ranoj dijagnostici meri značajnim opadanjem trenda u broju obolelih i broju umrlih u poslednjih 60 godina. Međutim, Papanikolau test nije 100% tačan, te procenat lažno negativnih rezultata i dalje predstavlja problem koji prati izvođenje ovog testa. I dok su u razvijenim zemljama organizovani skrining programi uspeli da nadomeste nedovoljnu senzitivnost Papanikolau testa, u nerazvijenim zemljama iz kojih potiče čak 80% slučajeva karcinoma grlića materice, u kojima ne postoje uslovi za sprovođenje ovakvih programa, potreba za jeftinijim i efikasnijim testom raste.

AB  - Diagnostic tests used in clinical practice have the undeniable impact on reducing mortality related to different types of cancer. Since more than 85% of all cancers originate in epithelial tissue, cervix is chosen to be a testing material in this doctoral dissertation. When it comes to cervical cancer, Papanicolaou test is still the most effective screening test for cervical cancer detection. Its importance is reflected in decreasing trend in mortality and number of diseased in the last 60 years. However, Papanicolaou test is not 100% accurate with the main problem being high percentage of false negative results. This problem of low sensitivity is partially resolved in developed countries with organized screening programs. Still, since about 80% of cervical cancer cases occurr in less developed countries, where the cost of screening program implementation is not affordable and infrastructure is not satisfying, the need for cost-effective screening test is rising. This is why the tendency in scientific world nowadays is to develop automated diagnostic system that would minimize „human error“ and allow effective screening even in low resource settings...

abstract = "Savremeni dijagnostički testovi koji se koriste u kliničkoj praksi imaju neosporan uticaj na smanjenje smrtnosti kao posledice obolevanja od različitih tipova kancera. S obzirom da više od 85% kancera potiče iz epitelnog tkiva, za istraživanje u okviru ove doktorske disertacije je izabran grlić materice kao jedan od predstavnika epitelnih tkiva. Kada govorimo o kanceru grlića materice, Papanikolau test još uvek predstavlja nezamenljiv skrining test čiji se uticaj u ranoj dijagnostici meri značajnim opadanjem trenda u broju obolelih i broju umrlih u poslednjih 60 godina. Međutim, Papanikolau test nije 100% tačan, te procenat lažno negativnih rezultata i dalje predstavlja problem koji prati izvođenje ovog testa. I dok su u razvijenim zemljama organizovani skrining programi uspeli da nadomeste nedovoljnu senzitivnost Papanikolau testa, u nerazvijenim zemljama iz kojih potiče čak 80% slučajeva karcinoma grlića materice, u kojima ne postoje uslovi za sprovođenje ovakvih programa, potreba za jeftinijim i efikasnijim testom raste. Pogrešno postavljene dijagnoze često su posledica ljudske greške, pa se kao rešenje nameće automatizacija dijagnostičkog procesa. Analizirajući ovu problematiku, javila se ideja o testiranju patentirane metode Optomagnetne imidžing spektroskopije na uzorcima ćelija grlića materice i njenoj primeni u dijagnostici karcinoma grlića materice.

AB  - This paper presents an effective design method of PID controller with series differential compensator ie. PIDC controller. The adjustable parameters of a PIDC controller are:
proportional gain kp, integral gain ki, derivative gain kd, the second order derivative gain kh and filter time constant Tf. The proposed design procedure is based on pole placement to
approximately obtain dynamics of the closed loop system defined with the poles of the criterion test function which has optimal performance in sense of minimal settling time without overshoot.
The design goal is to obtain good load disturbance response with constraint on robustness, so parameter kp is selected to guarantee desired robustness given in the form of closed loop maximum sensitivity Ms and considering sensitivity to the measurement noise Mn. This technique is applicable to a wide range of transfer functions: stable and unstable, with and without time-delay,
rational and non-rational and those describing distributed parameters. Validity of a proposed method is verified through a series of numerical simulations of processes typically encountered
in industry.
