description: Milk holds a special position among other animal and other plant fruit, due to the fact that it is an exclusive food for human but mammals as well, at their first stage of life. This product, however, is the key element in man’s nutrition not only in its first stage of life, but later as well. It is the most Full, simple and natural food, because it includes ingredients like fat and lactose, which provide human with energy, proteins and minerals that contribute in its structural components. Furthermore, it includes enough vitamins and minerals in order to fulfill the necessary biochemical procedure. Consumers usually ignore the simple truths of milk’s great nutrition as food. This lack of information is covered by advertisement, as advertisement is called the massive information of consumers about the special characteristics of a product, in order to convince the consumers to buy it. The results from the quality research, extracted important conclusions, which together with the literature review were used for the questionnaire’s development and the conduction of the quantitative research. By this research, the results that come up show the effects of advertisement in fresh milk consumer’s behavior that belongs to residents of Thessaloniki.
VP6-04: Title: Magnetic Tunnel Junction Molecular Spintronics-based chemical sensing device

Magnetic Sensors and High Frequency Devices (Virtual)
The Magnetic Tunnel Junction (MTJ) was first successfully fabricated and tested in the 90s. it consists of a Tri-layer of two ferromagnets, sandwiching a 2nm ultra-thin layer of dielectric or insulator called the tunneling barrier. If a voltage is applied to the ferromagnets, electrons can tunnel across the barrier in a process called quantum mechanical tunneling. The tunneling current in this case is maximum if the direction of magnetization of the two electrodes are parallel to each, and minimum when the two electrodes are anti-parallel to the direction of magnetization. The tunneling current and resistance of this device will therefore change in response to changes in the magnetic orientation of the two ferromagnetic electrodes. The Magnetic Tunnel Junction Molecular spintronic device (MTJMSD) can transform ferromagnetic materials and produce intriguing spin transport characteristics with high sensitivity, low power consumption, very small in size, and less expensive. This disclosure is directed toward a new MTJ-based spintronics device for converting chemical absorption into a change in magnetoresistance. Due to its high sensitivity, excellent scalability, and low power consumption, MTJMSD-based sensors can be widely implemented in different applications. In our investigation, we tested some commonly used chemicals in the lab on our device, both at the excited state (with light) and at the ground state (in the dark) We tested Acetone (CH3COCH3), Ethyl Alcohol (CH2CHOH) and Dichloromethane (CH2Cl2) and studied the trend. The IV measurements were conducted before and after molecular attachment. There was no clear distinction in the detectivity between the measurement done under the light and in the dark, however, a general observation before and after molecular attachment showed a significant increase in the current. In the present work, we fabricated a metal/insulator/semiconductor MTJ as a testbed for our MTJMSD-based chemical sensing device. This paper is part of an ongoing investigation with the aim of fabricating an MTJMSD-based sensor for the detection of dopamine concentration and other chemicals.References: [1] H.

description: The rate of nuclear muon capture by the proton has been measured using a new experimental technique based on a time projection chamber operating in ultra-clean, deuterium-depleted hydrogen gas at 1 MPa pressure. The capture rate was obtained from the difference between the measured $μ^-$ disappearance rate in hydrogen and the world average for the $μ^+$ decay rate. The target's low gas density of 1% compared to liquid hydrogen is key to avoiding uncertainties that arise from the formation of muonic molecules. The capture rate from the hyperfine singlet ground state of the $μp$ atom is measured to be $Λ_S=725.0 \pm 17.4 s^{-1}$, from which the induced pseudoscalar coupling of the nucleon, $g_P(q^2=-0.88 m_μ^2)=7.3 \pm 1.1$, is extracted. This result is consistent with theoretical predictions for $g_P$ that are based on the approximate chiral symmetry of QCD.

description: We develop the BRST approach to gauge invariant Lagrangian construction for the massive mixed symmetry integer higher spin fields described by the rank-two Young tableaux in arbitrary dimensional Minkowski space. The theory is formulated in terms of auxiliary Fock space. No off-shell constraints on the fields and the gauge parameters are imposed. The approach under consideration automatically leads to a gauge invariant Lagrangian for massive theory with all appropriate Stuckelberg fields. It is shown that all the restrictions defining an irreducible representation of the Poincare group arise from Lagrangian formulation as a consequence of the equations of motion and gauge transformations. As an example of the general procedure, we derive the gauge-invariant Lagrangian for massive rank-2 antisymmetric tensor field containing the complete set of auxiliary fields and gauge parameters.

description: As a first step towards a realistic phenomenological description of vector and axial-vector mesons in nuclear matter, we calculate the spectral functions of the $ρ$ and the $a_1$ meson in a chiral baryon-meson model as a low-energy effective realization of QCD, taking into account the effects of fluctuations from scalar mesons, nucleons, and vector mesons within the Functional Renormalization Group (FRG) approach. The phase diagram of the effective hadronic theory exhibits a nuclear liquid-gas phase transition as well as a chiral phase transition at a higher baryon-chemical potential. The in-medium $ρ$ and $a_1$ spectral functions are calculated by using the previously introduced analytically-continued FRG (aFRG) method. Our results show strong modifications of the spectral functions in particular near the critical endpoints of both phase transitions which may well be of relevance for electromagnetic rates in heavy-ion collisions or neutrino emissivities in neutron-star merger events.

Constraints on gamma-ray burst and supernova progenitors through circumstellar absorption lines. (II): Post-LBV Wolf-Rayet stars

description: Van Marle et al. (2005) showed that circumstellar absorption lines in early Type Ib/c supernova and gamma-ray burst afterglow spectra may reveal the progenitor evolution of the exploding Wolf-Rayet star. While the quoted paper deals with Wolf-Rayet stars which evolved through a red supergiant stage, we investigate here the initially more massive Wolf-Rayet stars which are thought to evolve through a Luminous Blue Variable (LBV) stage. We perform hydrodynamic simulations of the evolution of the circumstellar medium around a 60 Msol star, from the main sequence through the LBV and Wolf-Rayet stages, up to core collapse. We then compute the column density of the circumstellar matter as a function of radial velocity, time and angle. This allows a comparison with the number and blue-shifts, of absorption components in the spectra of LBVs, Wolf-Rayet stars, Type Ib/c supernovae and gamma-ray burst afterglows. Our simulation for the post-LBV stage shows the formation of various absorption components, which are, however, rather short lived; they dissipate on time scales shorter than 50,000yr. As the LBV stage is thought to occur at the beginning of core helium burning, the remaining Wolf-Rayet life time is expected to be one order of magnitude larger. When interpreting the absorption components in the afterglow spectrum of GRB-021004 as circumstellar, it can be concluded that the progenitor of this source did most likely not evolve through an LBV stage. However, a close binary with late common-envelope phase (Case C) may produce a circumstellar medium that closely resembles the LBV to Wolf-Rayet evolution, but with a much shorter Wolf-Rayet period.

description: Phase change memories (PCM) is an emerging type of non-volatile memory that has shown a strong presence in the data-storage market. This technology has recently attracted significant research interest in the development of non-Von Neumann computing architectures such as in-memory and neuromorphic computing. Research in these areas has been primarily motivated by the scalability potential of phase change materials and their compatibility with industrial nanofabrication processes. In this work, we are presenting our development of crossbar phase change memory arrays through the electrodeposition of GeSbTe (GST). We show that GST can be electrodeposited in microfabricated TiN crossbar arrays using a scalable process. Our phase switching test of the electrodeposited materials have shown that a SET/RESET resistance ratio of 2-3 orders of magnitude is achievable with a switching endurance of around 80 cycles. These results represent the first phase switching of electrodeposited GeSbTe in microfabricated crossbar arrays. Our work paves the way towards developing large memory arrays involving electrodeposited materials for passive selectors and phase switching devices. It also opens opportunities for developing a variety of different electronic devices using electrodeposited materials.

description: We investigate faint radio emission from low- to high-luminosity Active Galactic Nuclei (AGN) selected from the Sloan Digital Sky Survey (SDSS). Their radio properties are inferred by co-adding large ensembles of radio image cut-outs from the FIRST survey, as almost all of the sources are individually undetected. We correlate the median radio flux densities against a range of other sample properties, including median values for redshift, [OIII] luminosity, emission line ratios, and the strength of the 4000A break. We detect a strong trend for sources that are actively undergoing star-formation to have excess radio emission beyond the ~10^28 ergs/s/Hz level found for sources without any discernible star-formation. Furthermore, this additional radio emission correlates well with the strength of the 4000A break in the optical spectrum, and may be used to assess the age of the star-forming component. We examine two subsamples, one containing the systems with emission line ratios most like star-forming systems, and one with the sources that have characteristic AGN ratios. This division also separates the mechanism responsible for the radio emission (star-formation vs. AGN). For both cases we find a strong, almost identical, correlation between [OIII] and radio luminosity, with the AGN sample extending toward lower, and the star-formation sample toward higher luminosities. A clearer separation between the two subsamples is seen as function of the central velocity dispersion of the host galaxy. For systems with similar redshifts and velocity dispersions, the star-formation subsample is brighter than the AGN in the radio by an order of magnitude. This underlines the notion that the radio emission in star-forming systems can dominate the emission associated with the AGN.

Soft Magnetic Materials (Virtual)
Motor cores usually operate under stress loads, and the stresses can have an effect on their magnetostriction. When the Si content of electrical steel is 3.5%, the mechanical stress can cause magnetostriction saturation, resulting in increased motor vibration [1]. It has been reported that when the Si content of electrical steel reaches 6.5%, the magnetostriction effect is not obvious [2]. Therefore, it is particularly important to study the evolution of the magnetostrictive properties of electrical steels with different Si contents as influenced by stress. In the second part of this paper, the magnetostrictive properties of electrical steels with different Si contents (1.5%, 2.5%, 2.8%, 3.2%, 6.5%) were tested under variable stresses by using the magnetostrictive properties test method with loading stress along the rolling direction as shown in Fig. 1, and some experimental results are shown in Fig. 2, which reveal the hysteresis line and magnetostrictive properties of electrical steels with different Si contents under the influence of stress The third part extracts the magnetostriction The third part extracts the magnetostrictive strain, saturation wall shift magnetization strength and other key parameters based on the test results, and explains the reasons for the variation of magnetostrictive properties of electrical steels with different Si content under stress field from both macroscopic test data and microscopic mechanism of material magnetization behavior. In the fourth part, based on the above analysis, a finite element model of motor cores with different Si contents of electrical steel is established, and the noise analysis is carried out for the cores with and without considering the influence of stress to investigate the law that stress affects the core vibration noise by influencing the magnetostrictive properties of the material with different Si contents. Eventually, this paper will complete the test of magnetostriction characteristics of electrical steels with different Si content under variable stress and the analysis of the causes of microscale, which will be of great guidance to the design of low-noise motors.References: [1] Sablik, M.

Thin Films, Multilayers and Interface Effects (Virtual)
New types of metamaterials can be produced by enhancing the magnetic coupling between the two ferromagnetic layers of a magnetic tunnel junction (MTJ). One potential method to achieve strong coupling involves attaching molecules along the exposed side of the MTJ, acting as spin channels that connect the top and bottom ferromagnetic layers. This study focuses on examining the coupling effect of Single Molecule Magnetic (SMM) on MTJs with varying insulator thicknesses. The fabrication process of the MTJ involves coating a silicon wafer with photoresist through spin coating, creating patterns via photolithography, depositing thin films through sputtering, and finally removing the unwanted material through liftoff. After fabrication, the top and bottom electrodes are covalently connected on the exposed side edges using SMMs to establish a strong magnetic coupling. Through multiple experiments, it has been observed that strong coupling, facilitated by SMM channels, alters the magnetic properties of both ferromagnetic metals. Electron spin resonance (ESR) is a valuable technique utilized to characterize the magnetic properties, interactions, and dynamics of the individual layers within the structure of a magnetic tunnel junction (MTJ). In this study, an ESR investigation was conducted both before and after the treatment of the MTJ with the SMM to assess the impact of the molecules. The ESR results displayed a discernible shift in the acoustic and optical modes of the MTJ subsequent to the introduction of the SMM. This shift observed in the ESR spectra indicates that the SMM has a significant effect on the properties of the ferromagnetic electrodes within the MTJ. To understand the SMM impact, the ESR response of the heated MTJs was compared. It was found that the shift induced by the SMM on the MTJ was of a similar magnitude to the shift observed on a heated sample. Examining the influence of SMM coupling in magnetic tunnel junctions (MTJs) is of utmost importance, as MTJs based on molecular components open up novel possibilities for nanoscale electronics, quantum information processing, and advanced sensor technologies.

3D Magnetism
In recent years, there has been a surge of interest in expanding from two to three dimensional (3D) magnetic systems [1,2]. This extra dimension brings new magnetic textures [3-5], which promise applications in information storage and processing [6,7]. The detection and 3D visualization of these nanometric magnetic textures has been made possible by the development of magnetic tomography [8]. We have recently extended magnetic tomography to soft X-ray holography, allowing for the high spatial resolution imaging of textures within thick samples [9]. Secondly, we have combined 3D X-ray magnetic imaging with the application of in situ magnetic fields, allowing for the tracking of the field-driven motion of topological magnetic defects, such as Bloch points, merons and vortices [10]. These advances establish necessary capabilities for the study of the behavior of topological textures in 3D, opening the door to insights into three dimensional magnetic textures.References: [1] Streubel et al., J.

Magnetoresistance and Associated Effects (Virtual)
Tri-layer magnetic tunnel junction(MTJ) has emerged as a building block for engineering propitious integrated circuits with meager energy consumption (Fig. 1(a)). High switching energy(≈50 fJ) and low TMR(≈ 200%)[1,2] are the bottlenecks that hinder its possibility of becoming a superior alternative for static and dynamic random access memory. In this work, we introduce a device featuring a minimalistic non-uniform superlattice (Fig. 1(b)) instead of the oxide layer in a conventional MTJ premised on the self-consistent coupling of the Non-Eqilibrium-Green's Function and the Landau-Liftshitz-Gilbert-Slonczewski equation. We find the presence of electronic Bloch states in the neighborhood of resonant peaks in the proposed non-uniform superlattice(Nu-SL) gives rise to a highly spin-selective box car-shaped transmission. This adaptation enables a high TMR(%) in the order of 3×104%(Fig.2(f)) and a significant reduction(Fig.2(h)) in the spin transfer torque switching bias (88%). As a result of the high opposite spin transmission, the spin filtering capability of an MTJ suffers a decline while failing to generate a large spin current(IS = Iup−Idown). This gives rise to a high switching bias resulting in higher switching energy. Comparative studies divulge that the proposed Nu-SL-based tunnel junction(Nu-SLTJ) is capable of rendering far superior spin-selectivity via broadband tunneling and thus may lay the bedrock for exploring the horizon of heterostructure-based spintronic devices in the near future.References: 1.

description: We have conducted an extensive wide-field imaging survey for Cepheid variables in the Local Group irregular galaxy WLM. From data obtained on 101 nights, we have discovered 60 Cepheids which include 14 of the 15 Cepheid variables previously detected by Sandage and Carlson. Down to a period of 3 days, our Cepheid survey in WLM should be practically complete. Importantly, we have found for the first time a long-period Cepheid (P=54.2 days) in this galaxy, alleviating the puzzle that WLM with its many blue, massive stars does not contain Cepheids with periods longer than about 10 days. Our data define tight period-luminosity relations in V, I and the reddening-free Wesenheit magnitude ${\rm W}_{\rm I}$ which are all extremely well fit by the corresponding slopes of the LMC Cepheid PL relation, suggesting no change of the PL relation slope down to a Cepheid metal abundance of about -1.0 dex, in agreement with other recent studies. We derive a true distance modulus to WLM of 25.144 $\pm$0.03 (r) $\pm$0.07 (s) mag from our data, in good agreement with the earlier 24.92 $\pm$ 0.21 mag determination of Lee, Freedman and Madore (1993a) from Cepheid variables. The quoted value of the systematic uncertainty does not include the contribution from the LMC distance which we have assumed to be 18.50 mag, as in the previous papers in our project.

Interdisciplinary Topics II: Magnetic Forces and Nanoparticles; Biomedicine; Education and Outreach
Magnetic nanowires (MNWs) are desirable for heating applications due to their square hysteresis loops and their size which allows for tunable switching fields. However, because MNWs are readily modified, a vast design space is available when applying magnetic nanowires to different heating applications. Here, major and minor hysteresis loops have been measured for ferromagnetic nanowire arrays. These experimental results have been used to project heating rates and energy loss per cycle for nanowires depending on the equipment constraints used to heat the nanowires. These constraints include maximum frequency and applied magnetic field. In this work, these heating maps allow for informed design and fabrication of nanowires for cryopreservation applications, especially when paired with simulation. However, these heat rate maps are broadly applicable for understanding the thermal behavior of nanowires in broader applications including electronics and hyperthermia.

description: The deep crustal heating, associated with exothermal nuclear reactions, is believed to be a key parameter for describing the thermal evolution of accreting neutron stars. In this paper, we present the first thermodynamically consistent calculations of the crustal heating for realistic compositions of thermonuclear ashes. In contrast to previous studies based on the traditional approach, we account for neutron hydrostatic/diffusion (nHD) equilibrium condition imposed by superfluidity of neutrons in a major part of the inner crust and rapid diffusion in the remaining part of the inner crust. We apply a simplified reaction network to model nuclear evolution of various multi-component thermonuclear burning ashes (superburst, KEPLER, and extreme rp-process ashes) in the outer crust and calculate the deep crustal heating energy release Q, parametrized by the pressure at the outer-inner crust interface, P_{oi}. Using the general thermodynamic arguments, we set a lower limit on Q, Q>0.13-0.2 MeV per baryon (an actual value depends on the ash composition and the employed mass model).

description: Many features of dimensional reduction schemes are determined by the breaking of higher dimensional general covariance associated with the selection of a particular subset of coordinates. By investigating residual covariance we introduce lower dimensional tensors --generalizing to one side Kaluza-Klein gauge fields and to the other side extrinsic curvature and torsion of embedded spaces-- fully characterizing the geometry of dimensional reduction. We obtain general formulas for the reduction of the main tensors and operators of Riemannian geometry. In particular, we provide what is probably the maximal possible generalization of Gauss, Codazzi and Ricci equations and various other standard formulas in Kaluza-Klein and embedded spacetimes theories. After general covariance breaking, part of the residual covariance is perceived by effective lower dimensional observers as an infinite dimensional gauge group. This reduces to finite dimensions in Kaluza-Klein and other few remarkable backgrounds, all characterized by the vanishing of appropriate lower dimensional tensors.

Magnetization Dynamics and Switching (Virtual)
Spin-orbit torque (SOT) induced magnetization switching occurs via either coherent switching or domain nucleation followed by domain wall (DW) propagation. This study reveals that the energy required in domain nucleation is up to five times higher than DW propagation to achieve magnetization switching. Hence, the minimization of the domain nucleation energy is critical to the optimization of energy efficiency. To capitalize on the energy difference between domain nucleation and DW propagation, we propose a two-pulse scheme that utilizes a brief high-power pulse to initiate domain nucleation followed by a longer low-power pulse for DW propagation. The two-pulse scheme can achieve energy savings of up to 72 % compared to using a single-pulse scheme. In the two pulse schemes, we conducted further investigations on the effects of various parameters on magnetization switching, including nucleation pulse width τnu, propagation pulse width τp, and the interval Δτ between two pulses. Figure 1(a) provides the illustration of τnu on switching. To ensure complete switching, τp was set to an excessive value of 2 ns. Figure 1(b) demonstrates a clear minimum value of τnu required for achieving full switching, as well as a rapid decrease and saturation of switching time with increasing τnu. The influence of τp on switching is illustrated in Fig. 1(c). Here, we observe a straightforward relationship where the minimum value of τp required for achieving full switching is considered optimal. Figure 1(d) showcases the increasing degree of switching with increasing τp. When τp is insufficient, an oscillatory behavior in perpendicular magnetization is observed, which corresponds to the back hopping of the DW. Figure 1(e) provides an illustration of the influence of Δτ on switching. We observe a maximum threshold value of Δτ = 0.10 ns, above which full switching cannot be achieved. Additionally, we observe a decrease in switching time below this threshold, as depicted in Fig. 1(f).References:

description: On the torus group, on the group of p-adic integers and on the p-adic solenoid, we give a construction of an arbitrary weakly infinitely divisible probability measure using a random element with values in a product of (possibly infinitely many) subgroups of the real numbers. As a special case of our results, we have a new construction of the Haar measure on the p-adic solenoid.

description: The European project RE-InVEST re-assesses the role of active labour market and social protection policy for integrating vulnerable groups from a social investment perspective that the EU endorsed as a response to the financial crisis. This Belgian national case study of RE-InVEST used peer research to investigate the nature and effect of relevant policies concerning unemployed persons with a migratory background. This report analyses the counselling services in Flanders, where two services have the task to reintegrate unem­ployed people. The main research question is the quality of the counselling and the possible differences between the counselling services. Lessons can be learned from these analyses. The qualitative research addresses the question if the counselling comply with the social investment perspective from a human rights and capability approach. We detected that the counselling has negative consequences for the clients, espe­cially for people with a migratory background. It increases fatalism among people with a migratory back­ground. Those people tend to lose every hope for an opportunity to develop their talents or any hope for a life they have reason to value. The unilateral focus on the demand side and a lack of insight in the supply side has negative consequences on participation, agency and choice. Though activation is a goal, counselling is not guided by social investment in general.
Planning for Safe Abortable Overtaking Maneuvers in Autonomous Driving

description: Overtaking is one of the most challenging tasks in driving, and the current solutions to autonomous overtaking are limited to simple and static scenarios. In this paper, we present a method for behaviour and trajectory planning for safe autonomous overtaking. The proposed method optimizes the trajectory by simultaneously enforcing safety and minimizing intrusion onto the adjacent lane. Furthermore, the method allows the overtaking to be aborted, enabling the autonomous vehicle to merge back in the lane, if safety is compromised, because of e.g. traffic in opposing direction appearing during the maneuver execution. A finite state machine is used to select an appropriate maneuver at each time, and a combination of safe and reachable sets is used to iteratively generate intermediate reference targets based on the current maneuver. A nonlinear model predictive controller then plans dynamically feasible and collision-free trajectories to these intermediate reference targets. Simulation experiments demonstrate that the combination of intermediate reference generation and model predictive control is able to handle multiple behaviors, including following a lead vehicle, overtaking and aborting the overtake, within a single framework.

description: We have carried out extensive low-temperature (1.5 to 10 K) measurements of the critical field, $H_c$, for the element Pb up to a pressure of $P=1.2$ GPa. From this data the electronic entropy, specific heat, thermal expansion coefficient and compressibility is calculated as a function of temperature, pressure and magnetic field. The zero-field data is consistent with direct thermodynamic measurements and the $P$-dependence of $T_c$ and specific heat coefficient, $γ(T,P)$ allows the determination of the $P$-dependence of the pairing interaction.

description: We review the nucleosynthesis yields of core-collapse supernovae (SNe) for various stellar masses, explosion energies, and metallicities. Comparison with the abundance patterns of metal-poor stars provides excellent opportunities to test the explosion models and their nucleosynthesis. We show that the abundance patterns of extremely metal-poor (EMP) stars, e.g., the excess of C, Co, Zn relative to Fe, are in better agreement with the yields of hyper-energetic explosions (Hypernovae, HNe) rather than normal supernovae. We note that the variation of the abundance patterns of EMP stars are related to the diversity of the Supernova-GRB connection. We summarize the diverse properties of (1) GRB-SNe, (2) Non-GRB HNe/SNe, (3) XRF-SN, and (4) Non-SN GRB. In particular, the Non-SN GRBs (dark hypernovae) have been predicted in order to explain the origin of C-rich EMP stars. We show that these variations and the connection can be modeled in a unified manner with the explosions induced by relativistic jets. Finally, we examine whether the most luminous supernova 2006gy can be consistently explained with the pair-instability supernova model.

description: Σκοπός της διατριβής ήταν να αποδειχθεί με την πειραματική επιβεβαίωση της θεωρίας σχεδίασης συστημάτων αυτομάτου ελέγχου μίας εισόδου-μίας εξόδου τύπου - Ι και της υλοποιήσης του αυτόματα ρυθμιζόμενου ελεγκτή PID, ότι είναι δυνατή η χρησιμοποίησή της στον τομέα της βιομηχανίας. Αρχικά, υλοποιείται η πειραματική διάταξη (Hardware-In-the Loop HIL) πάνω στην οποία έγινε η πειραματική επιβεβαίωση. Η προσομοίωση HIL πραγματικού χρόνου (real time Hardware-In-the-Loop) αναγνωρίζεται ευρέως πλέον, ως ένα από τα σημαντικότερα εργαλεία σχεδίασης για τους Μηχανικούς. Αρχικός στόχος της διατριβής ήταν ο προσδιορισμός των παραμέτρων των ψηφιακών ελεγκτών I, PI και PID που χρησιμοποιούνται για τον έλεγχο των συστημάτων με πραγματικούς πόλους, με πραγματικούς πόλους και μηδενικά ελάχιστης και μη ελάχιστης φάσης, καθώς και των φυσικών συστημάτων με πραγματικούς πόλους και χρονική καθυστέρηση, χρησιμοποιώντας και την κλασική και την αναθεωρημένη μέθοδο του βέλτιστου πλάτους και έγινε μια σύγκριση μεταξύ των δύο αυτών μεθόδων.

Κατά την υλοποίηση αυτή, αναπτύχθηκε μία συστηματική διαδικασία αυτορρύθμισης των παραμέτρων του ψηφιακού ελεγκτή, με τέτοιο τρόπο, ώστε το τελικό σύστημα κλειστού βρόχου να εμφανίζει τη βέλτιστη μορφή του μεταβατικού φαινομένου.
description: The aim of the thesis was to be proved the experimental confirmation of general theory of designing of automatic control systems single input-single output of type - I and the implementation of automatically regulated controller PID, that it is possible its use in industry. Initially, it is implemented the experimental setup (Hardware-In-the Loop HIL) on which experimental verification took place. The real time Hardware - In - the - Loop is recognized as an important tool of designing for engineers. The initial aim of this thesis was the determination of parameters of digital controllers I, PI and PID that are used for the control of systems with real poles, with real poles and zeros in left and right complex level and the natural systems with real poles and time delay using both the classical and the revised method of Magnitude Optimum criterion and a comparison was made between these two methods. Completing this thesis, with the implementation of automatically regulated controller PID. In this implementation, it is developed a systematic process of automatically regulated the parameters of digital controller, in such way that the final closed loop system presents the optimal form of transient phenomenon.
