In this paper we study the DYNAMICS of long-range pairing and hopping p-wave superconducting chain after a ‎sudden quench of chemical potential. We have shown that the quantum-classical phase transition occurs ‎when the system is quenched to the critical point and the Loschmidt echo shows perfect periodic oscillations. ‎Moreover we have studied the dynamical phase transition for a quench across the critical point. Our analysis ‎shows that the dynamical phase transition occurs for the cases where the system initially prepared in the ‎massless edge MODEs. While the system does not show dynamical phase transition when the system is ‎prepared in the massive edge MODEs, even the quench crossing the critical point‎‎.

In this paper, a new procedure for designing the guidance law considering the control loop DYNAMICS is proposed. The nonlinear guidance loop entailing a first order lag as the control loop DYNAMICS is formulated. A new finite time and smooth back stepping sliding MODE control scheme is used to guarantee the finite time convergence of relative lateral velocity. Also in the proposed algorithm the chattering is removed and a smooth control signal is produced. Moreover, the target maneuver is considered as an unmatched uncertainty. Then a robust guidance law is designed without requiring the precise measurement or estimation of target acceleration. Simulation results show that the proposed algorithm has better performance as compared to the proportional navigation, augmented PN and the other sliding MODE guidance law.

The body freedom flutter phenomenon is one of the aeroelastic instabilities that occurs due to the coupling of the aeroelastic bending MODE of the wing with the short-period MODE in the flight DYNAMICS of the aircraft. By using the aeroservoelastic MODEl and applying closed loop control, this phenomenon can be suppressed in the operating conditions of the aircraft and the velocity of this event can be increased. The simplest MODEl aircraft capable of displaying this instability includes the flexible wing and the planar flight DYNAMICS MODEl. For this purpose, the wing structure is MODEled using the Euler-Bernoulli beam and, the theory of minimum variable state is used to MODEl unstable aeroDYNAMICS to make the conditions suitable for MODEling the system in state space. In the control section, the elevator is used as the control surface and LQR theory with Kalman filter is used to body freedom flutter suppression. Finally, the effect of adding a closed loop control to increase the body freedom flutter velocity and the limitations of this work are studied.

Introduction: Patent ducfus arteriosus (PDA) is the persistence of a normal fetal structure between left pulmonary artery and descending aorta. Persistence of this fetal structure beyond 10 days of life is considered abnormal. In this study we compared M-MODE and Doppler echocardiography in diagnosis of PDA in children at Aliasghar Hospital in Zahedan and Children hospital in Bandar Abbas for one year. methods: We selected 62 patients that were suspicious to have PDA on physical examination. It should be mentioned that we omitted patients with other cgngenital cardiac abnormalities such as truncus arteriosus, ASD, VSD and AZSD. Our patients were below 15years old. Before echocardiography, physical examination, CXR and ECG were done for the patients. Then, they were evluated with both M-MODE and Doppler Echocardiography and finally results were statistically analyzed.Results: Out of 62 patients, 34 were female and 28 were male. 51.6% patients were less than one year old and others were older. 85% of patients had cardiac murmur on physical examination and in 50% of them pulmonary component of second heart sound was increased. Peripheral pounding pulses were present in 85% of patients. In chest X-Ray, 82.3% of patients had increased cardiothoracic ratio and pulmonary vascular markings were increased in 85.5% of them. On ECG, 58.1 % of patients had signs of right and left or bilateral ventricular hypertrophy. Pulmonary hypertension was also seen in 51.6% of patients. PDA was diagnosed with M-MODE echocardiography in 56 patients (90.3 %) and with Doppler echocardiography in 61 patients (98.4%). According to McNemar statistical analysis, there was not an obvious difference between these two. methods of echocardiography in PDA diagnosis (p=0.125).Conclusion: Findings of this study showed that M-MODE and Doppler echocardiography for diagnosis of PDA in children are similar and again attention to M-MODE echocardiography can be helpful in diagnosis of PDA in children especially restless infants and neonates.

Molecular DYNAMICS simulation has been performed to analyze the effect of the presence of gold nanoparticle on DYNAMICS of Kob-Anderson binary Lennard-Jones mixture upon supercooling within the framework of the MODE coupling theory of the dynamic glass transition. The presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution functions to become shorter with respect to the bulk binary Lennard-Jones liquid. It is found that the DYNAMICS of the liquid at a given density is consistent with the MODE coupling theory (MCT) predictions. In accordance with the idealized MCT, the diffusion constants D(T) show power-law behavior at low temperatures for both types of binary Lennard-Jones (BLJ) particles as well as the 13 gold atoms comprising the nanoparticle. The MODE coupling crossover temperature Tc is the same for all particle types, however, Tc=0.4 is reduced with respect to that of the bulk BLJ liquid and the exponent is found to depend on the particle type. The existence of the nanoparticle causes the short-time b-relaxation regime to shorten and the range of validity of the MCT shrink with respect to the bulk BLJ. It is also found that the behavior of intermediate scattering function (ISF) is in agreement with MCT prediction and in spite of the presence of gold nanoparticle the time temperature superposition principle at intermediate and low temperatures is still valid and the curves of ISF vs. t/t(T) fall onto a master curve.

Controller design for non-linear multi-input, multi-output systems, such as unmanned quadrotor vehicles, has always been a challenging issue due to the strong interconnection between state variables and highly nonlinear dynamic equations. In addition, quadrotor is an under-actuated non-linear dynamic device. Due to being under-actuated for moving in the horizontal direction, the combination of changes in the speed of the existing quadruple operators should be used. So that, by creating the angle between the quadrotor hypothetical plane and the horizon surface, the device can be forced to move in the longitudinal or transverse direction. Therefore, in the quadrotor control system, two nested control loops are required. An outer loop to determine the appropriate angle of the device relative to the horizon for horizontal movements and an inner loop that is required to angle of the device panel is equal to this angle. In this paper, a fuzzy hybrid super-twisting sliding MODE non-linear controller for controlling a sample quadrotor is designed. For this purpose, a fuzzy controller in the outer loop and a super twisting sliding MODE controller in inner loop are used. An important advantage of this strategy is that it optimizes the horizontal speed of the device. If the distance from the target is too high, the angle of the device panel also increases, and if the distance is reduced, the angle also decreases. As a result, the device reaches the target with the desired speed. The performed simulation results confirmed this fact.

This paper is proposed a novel topology of a single phase grid connected inverter in order to conquest the common MODE leakage current. There are many topologies presented so far, But none of them has the efficiency more than 98 percent. In this paper, a MODErn configuration is presented that, not only delete the common MODE leakage current, but also increase the efficiency and power density and is affordable. this inverter consists of 6 switches and 2 diodes that in compare with similar ones, it has less element number. Than the famous topologies like H5, H6 and HERIC, the power loss and voltage stress on switches are decreased. These aspects are appears due to exclusive leg configuration and the placement of switches and diodes. The freewheel path revealed, decoupled DC side from AC side of Inverter which results in disconnecting the common MODE current. This issue will modify the network reliability indices and maintain safety standards. Finally the performances of proposed inverter will be compared and evaluated with some available Inverters.
