PI fuzzy virtual actuator design for Takagi-Sugeno systems

The paper presents conditions suitable in design of Takagi-Sugeno proportional/integral fuzzy virtual actuators for the nonlinear continuous-time systems, controllable by the Takagi-Sugeno fuzzy output controllers in parallel distributed form. Considering measurable premise variables independent on the system inputs, the problem is formulated as an enhanced disturbance suppression concept, implying asymptotic stability of the closed-loop system after activation of the Takagi-Sugeno fuzzy virtual actuator. Demonstrating the separation principle for Takagi-Sugeno fuzzy virtual actuator design, the sufficient design conditions are outlined in the terms of linear matrix inequalities in adapted bounded real lemma structures. The method generates the Takagi-Sugeno fuzzy virtual actuator also in a parallel distributed form, to compile the sub-model closed-loops after the fuzzy virtual actuator activation by inference through the membership functions. Takagi-Sugeno fuzzy virtual actuator is performed as an autonomous algorithm that may be activated with dependence on the fault detection and isolation subsystem response.
Tonal Variants in the Bilingual Mental Lexicon

Bilinguals of Jinan Mandarin and Standard Chinese (SC) produce different tonal variants of the same Jinan word. These words typically share the same segmental composition as their SC counterparts. Among the tonal variants, usually only one variant is identical to the tonal contour of the SC counterpart (variant_id). The word-wise probability of variant_id varies between 0 and 1. Naming latency data were elicited for 400 Jinan words from 42 speakers to test how speakers of Jinan store the tonal variants, in particular, whether those who produce the variant_id might also store the tonally non identical variant (variant_ni) which they do not produce. We hypothesize that if a speaker who produces the variant_id does not store the unproduced variant_ni, the naming latency should only depend on the speaker’s choice of variant_id (yes/ no) and not on the word-wise probability of variant_id. On the other hand, if a speaker who produces the variant_id does store the unproduced variant_ni, the naming latency should depend on the word-wise probability of the speaker’s chosen variant. Our results provide support to the latter storage account.
STRESS ANALYSIS OF MANDIBULAR FULL FIXED PROTHESIS SUPPORTED BY THREE IMPLANTS WITH DIFERENT DISTAL TILTED IMPLANTS

This study evaluated the stresses induced in periimplant mandibular full fixed prosthesis by distinct designs. Six photoelastic models with 5 or 3 implants were fabricated, simulating edentulous mandible. Control group (C) received 5 upright implants and other models received 3 implants ranging the distal abutment straight (S) or angled (A) and the distal tilt implant 0 ̊, 17 ̊ or 30 ̊. Vertical loads were applied at two points of the framework: the distal implant and the final of cantilever. Twenty points were determined around near implant of the loading for stresses calculation. Statistical analysis was performed by ANOVA and Tukey's B test (α = 0.05). For the cantilever loading was not found statistical difference between groups (p = 195). Under distal implant loading the groups S17 and S30 were significantly higher than the group C (p = 0.000). The angled abutments not showed higher stress during the distal implant loading and the final of cantilever loading. The shear stress is at the cantilever loading than distal implant loading.
Optimized modulation in parallel neutral-point clamped inverters for circulating current reduction: A space vector analysis

Parallel Neutral-Point Clamped (NPC) inverters are commonly employed in medium voltage high power applications, such as wind energy system, smart transformer, and power conditioners. In literature, it is shown that the Phase Disposition modulation (PD) strategy provides better performance in terms of harmonic profile and current ripple for single NPC application. Therefore, the PD has been commonly employed as an optimal solution and used for optimized Space Vector Modulation (SVM). However, in case of interleaved operation and common dc-link, one of the main challenges is: the circulating current between inverters. With this consideration, comparisons between the PD and another carrier-based modulation — Alternative Phase Opposite Disposition (APOD) are carried out based on the space vector representation. The analysis shows that the APOD modulation offers much lower circulating current compared to the PD modulation, maintaining similar current ripple as well as spectrum quality of the total current. As a result, an APOD-based SVM technique is proposed in this paper, in order to reduce the circulating current and meanwhile maintain other superior characteristics. Full switching sequences as well as design criteria are presented for all sectors. Simulation and experimental results are provided to validate the effectiveness of the proposed modulation technique.
A Control Framework for Interactive Deformable Image Registration

A novel framework for interactive image registration is proposed. In this formulation, a closed loop system is created to control the PDE defining the registration evolution; a human expert user is present “in the loop” coupled with a convenient choice of automatic algorithm. The result is a system that leverages the expert’s high level anatomical knowledge with an automatic method’s speed in performing tedious correction tasks.
The H+/Cl- Symporter in Root-Hair Cells of Sinapis alba (An Electrophysiological Study Using Ion-Selective Microelectrodes)

In root-hair cells of Sinapis alba, cytosolic pH, cytosolic [Cl-], membrane potential, and membrane resistance have been measured to investigate proton-driven Cl- transport across the plasma membrane. Rapid lowering of the external pH transiently increased cytosolic [Cl-] and acidified the cytoplasm. To an abrupt increase in external [Cl-] the cells reacted with a rapid initial depolarization and a subsequent slower hyperpolarization, which was accompanied by an increase in cytosolic [Cl-] and [H+]. These results are indicative of an nH+/Cl- symport with n > 1. Simultaneous recording of the membrane potential, the proton motive force, cytosolic pH, and cytosolic [Cl-] reveals that kinetically this Cl- transport depends on the pH gradient across the plasma membrane rather than on the membrane potential.
Adaptive fuzzy output feedback control for a class of nonlinear pure-feedback systems with full state constraints

This paper is concerned with the problem of adaptive fuzzy output feedback control for a class of nonlinear pure-feedback systems with full state constraints. Because the systems have immeasurable states, the fuzzy state observers are designed to estimate the unmeasured states with the help of fuzzy logic systems to approximate the unknown nonlinear functions. A fuzzy adaptive output feedback control scheme is developed by incorporating the filtered signals into the backstepping recursive design, which guarantees that the full state constraints are not violated. All the signals of the closed-loop systems are bounded after employing Barrier Lyapunov Function (BLF), and the observer errors and the tracking errors of the systems converge to a small neighborhood of the origin by choosing the appropriate design parameters. Simulation studies show the effectiveness of the proposed approach.
Detection of Mycoplasma genitalium and Trichomonas vaginalis Infections in General Jordanian Patients

Problem statement: Both M. genitalium and T. vaginalis were recognized as important cause of sexually transmitted infections in developed countries. This study investigated the prevalence of M. genitalium and T. vaginalis in general Jordanian patients and their role of causing genitourinary tract diseases. Approach: A cross sectional study of 383 Jordanian adult patients aged between 19-78 years were investigated for presence of M. genitalium and T. vaginalis at the urology and obstetric-gynecology clinics at the Jordan University Hospital in Amman. First voided urine specimens were tested using urine microscopy, PCR for M. genitalium and T. vaginalis as well as culture for T. vaginalis. Results: The incidence of M. genitalium was higher and statistically significant (17/188, 9%, p = 0.022) than T. vaginalis (3/188; 1.6%) among patients diagnosed with specific urinary symptoms and signs, while this incidence was less but also significant in asymptomatic patients ( 7/195, 3.6% versus 1/195, 0.5%, p = 0.031), respectively. M. genitalium infection was frequently observed with urinary frequency (76%) and dysuria (59%) among symptomatic patients and more common in men than women (65% versus 35%, p = 0.51) and in married than singles (76% versus 24%, p = 0.59). Dual infection with both organisms was not recognized. Conclusion: Infection caused by M. genitalium and T. vaginalis was associated with higher incidence rate in patients with symptomatic genitourinary disease. Therefore, screening for their occurrence in such patients is important.
Model identification for impact dynamics of a piezoelectric microactuator

A parameterized model for the impact dynamics of a piezoelectric microactuator is proposed, and a system-identification procedure for quantifying model parameters is presented. The proposed model incorporates squeeze-film damping, adhesion and coefficient-of-restitution effects. Following parameter quantification from sample data of bouncing impacts and progressive ramped-square-wave inputs, the model is found to be effective in predicting the time response of the actuator to a range of square-wave and sinusoidal inputs. The main contributions of this paper are to show that the dynamic response to micro-scale contact can be predicted using simple lumped-parameter modeling after a proposed system-identification procedure is performed and that certain small-scale forces can be quantified. For example, for motions where bounce of the cantilever tip may occur, the range of adhesion is found to be time dependent and vary between approximately 20 and 520 nN, while the range of squeeze-film damping is estimated to be between 50 and 130 nN, depending on the input signal frequency and amplitude. The presence, absence and quantity of bounces upon impact are predicted very accurately, while oscillation amplitudes and contact durations are predicted to be between 1% and 30% error for the majority of many test cases of periodic inputs between 5 and 100 Hz.
An algorithmic approach based PSO-PID tuning of a real time conical tank process used in waste water treatment

Waste water treatment plant has become increasingly popular in many industrial and institutional sectors, to reduce water and soil contamination. Conical tank plays a vital role in the waste water treatment plant; it is very difficult to control the level of the conical tank as it has a non-linear property of changeable diameter and size. Hence, it needs a refined method to control the process and the most trustworthy one is using the Proportional Integral Derivative (PID) Controller. The PID controller is the standard feedback control tool and it makes up 90% of automatic controllers in process industries and is also the keystone for many advance control algorithms and strategies. For controlling the PID Controller, many tuning rules have been framed. However conventional PID controller offers suitable tuning but it does not provide an optimal tuning. In this paper we recommended the particle swarm optimization as an optimal tuning method.
A comparison of modern and historical methods for calculating Montgomery steamfunction

The suggestion has been made that the Montgomery streamfunction is now calculable for isentropic analysis purposes simply by applying the equation Ψ = gZ + cpT. Historically, this practice has been frowned upon, as measurements aloft did not have the accuracy requisite to allow such practice. Instead, an integral approach to calculating Ψ has been preferred to get workable values. Yet, advancements in the accuracy of radiosonde measurements have occurred, especially with global positioning system (GPS)‐verified height data. Herein, we show that the values from the simple and integral methods of getting Ψ are very similar, and differ by only ∼0.2%. © 2012 Royal Meteorological Society
An alternate set of basis functions for the electromagnetic solution of arbitrarily shaped, three‐dimensional, closed, conducting bodies using method of moments

In this work, we present an alternate set of basis functions, each defined over a pair of planar triangular patches, for the method of moments solution of electromagnetic scattering and radiation problems associated with arbitrarily shaped, closed, conducting surfaces. The present basis functions are point‐wise orthogonal to the pulse basis functions previously defined. The prime motivation to develop the present set of basis functions is to utilize them for the electromagnetic solution of dielectric bodies using a surface integral equation formulation which involves both electric and magnetic currents. However, in the present work, only the conducting body solution is presented and compared with other data. © 2008 Wiley Periodicals, Inc.

Suppression of Zero Sequence Circulating Current for Parallel Three-Phase Grid-Connected Converters Using Hybrid Modulation Strategy

The parallel three-phase grid-connected converters sharing dc and ac bus can increase the system power level effectively. However, the zero sequence circulating current (ZSCC) will occur inevitably under space vector pulse width modulation or discontinuous pulse width modulation (DPWM). In this paper, the mechanism and the mathematical model of ZSCC are studied. Then, a hybrid PWM (HPWM) strategy is proposed to suppress the ZSCC based on the same zero sequence voltage injected, which is dependent on the common grid information. The dc voltage utilization of HPWM can be extended compared with sinusoidal PWM (SPWM). The number of parallel modules can be infinity theoretically by using HPWM. It is noted that there is no internal commutation among modules (expect the dq current reference). Finally, the feasibility and the effectiveness of the proposed method are verified by experiments.

The parameters of our PID are computed using linear matrix inequality (LMI) technique and applied to active queue management (AQM) at router to avoid congestion. The results has been compared with other AQMs used in network like random early detection (RED) and random exponential markage (REM) in order to demonstrate the advantage of the present controller.
Clinical prioritizations and contextual constraints in nursing homes--a qualitative study.

AIM The aim of the study was to describe nurses' and physicians' experiences of prioritization factors in nursing homes. BACKGROUND What are the experiences of health care personnel when prioritizing treatment and care for elderly residents in nursing homes? Little research has been done in this area, yet with the growing elderly population and limited health care budgets there can be little doubt about its relevance. METHOD The study was conducted through semi-structured interviews with 13 physicians and nurses in six nursing homes. The interviews were analysed by manifest content analysis based on first- and second-level categories describing relevant factors. The categories were developed after preliminary readings of the texts. RESULTS This study revealed that there was a complex set of contextual constraints which influenced the care provided. There were three main findings: (i) some overall challenges related to providing good care to nursing home residents; these in turn influenced (ii) prioritizing dilemmas and (iii) factors influencing prioritization decisions. DISCUSSION Contextual constraints and higher level prioritizations seem to play a key role in clinical prioritizations in nursing homes. The combination of implicit rationing and the factors described as most predominant in the clinical prioritizations in nursing homes may result in inadequate and unjust health care services for some of the nursing home residents. In particular, those patients who do not speak up or do have comprehensive needs are at risk of being neglected.
The minority report: some common assumptions to reconsider in the modelling of the brain and behaviour

Reverse-engineering the brain involves adopting and testing a hierarchy of working hypotheses regarding the computational problems that it solves, the representations and algorithms that it employs and the manner in which these are implemented. Because problem-level assumptions set the course for the entire research programme, it is particularly important to be open to the possibility that we have them wrong, but tacit algorithm- and implementation-level hypotheses can also benefit from occasional scrutiny. This paper focuses on the extent to which our computational understanding of how the brain works is shaped by three such rarely discussed assumptions, which span the levels of Marr's hierarchy: (i) that animal behaviour amounts to a series of stimulus/response bouts, (ii) that learning can be adequately modelled as being driven by the optimisation of a fixed objective function and (iii) that massively parallel, uniformly connected layered or recurrent network architectures suffice to support learning and behaviour. In comparison, a more realistic approach acknowledges that animal behaviour in the wild is characterised by dynamically branching serial order and is often agentic rather than reactive. Arguably, such behaviour calls for open-ended learning of world structure and may require a neural architecture that includes precisely wired circuits reflecting the serial and branching structure of behavioural tasks.
RF properties of overdamped SIS junctions

A new type of nonhysteretic Josephson junction suitable for applications in voltage metrology has been developed. These junctions derive from the Nb/Al-AlO/sub x//Nb SIS junctions using a relatively thick Al layer oxidized at a low value of oxygen exposure. This produces junctions with reproducible and spatially homogeneous I-V characteristics, having current densities ranging from 10/sup 3/ to more than 2/spl times/10/sup 4/ A/cm/sup 2/ and characteristic voltages up to 0.40 mV. The authors report here the rf response of these junctions at 70 GHz. The authors have measured the dependence of the rf-induced steps on the microwave power and the stability of the steps, in view of a future application of these junctions to an AC Josephson voltage standard.
Optimal excitation of permanent magnet synchronous machines via direct computation of electromagnetic force components

Vibration of the stator along with pulsation of the electromagnetic torque on the rotor are known as sources of acoustic noise in permanent magnet synchronous machines (PMSMs). Magnetic design and stator excitation can be tailored to mitigate undesirable vibrations which are viewed as byproducts in electromechanical energy conversion process. In this paper, using direct computation of the radial and tangential components of the electromagnetic force in the airgap of a PMSM, stator excitation for elimination of various force harmonics is presented. The proposed method is based on a field reconstruction method that rapidly calculates the radial and tangential flux density and force components under arbitrary stator excitation. Using the field reconstruction method, stator current waveforms that minimize the ripple of both torque and radial force are derived subject to the constraint of maintaining a satisfactory level of torque density
Core and Back-End enhancements for CUPSHOP HW/SW partitioning tool

Hardware/Software co-design has become one of the main methodologies in modern embedded systems. The HW/SW partitioning problem is a central problem in Hardware/Software co-design. The recently-introduced Cairo University PSo-based Hardware/sOftware Partitioning (CUPSHOP) tool advanced the swarm intelligence optimization techniques to solve this problem. In this paper we introduce an augmented version of the CUPSHOP tool. This augmented CUPSHOP version adds an automatic RTL (VHDL) Back-End generation for the HW mapped components. It also complements the different hardware implementations alternatives already supported by the tool with the pipelined hardware alternative. Furthermore, it implements an improved pre-scheduling delay estimation formula.
Rapid, Efficient and High-Performance Protocol for Agrobacterium rhizogenes-Mediated Hairy Root Transformation of the Common Bean Phaseolus vulgaris

A rapid, efficient and high-performance transformation protocol employing Agrobacterium rhizogenes was developed for the common bean Phaseolus vulgaris. In this study, we examined competencies of various protocols to induce and explants that respond to hairy root transformation in bean plants. Utilizing young seedlings with severed radicles/hypocotyls, we developed a highly efficient procedure for achieving hairy root transformation frequencies as high as 100% as visualized by GUS reporter gene expression system. Transgenic hairy roots in these young composite plants were susceptible to nodulation by rhizobia, and form an excellent system for high throughput genomic analysis to study root biology and endosymbiosis in common bean.
Accuracy of motion correction methods for PET brain imaging

Recently published methods for motion correction in neurological PET include the multiple acquisition frame (MAF) and LOR rebinning methods. The aim of the present work was to compare the accuracy of reconstructions obtained with these methods when multiple, arbitrary movements were applied to a Hoffman brain phantom during 3D list mode acquisition. A reflective target attached to the phantom enabled a Polaris optical motion tracking system to monitor the phantom position and orientation in the scanner coordinate frame. The motion information was used in the motion correction algorithms. The MAF method was applied to the list-mode data after sorting them into a series of dynamic frames, while the LOR rebinning method was applied directly to the list-mode data. A proportion of the list mode events had to be discarded during rebinning because the application of the corrective spatial transformation removed them from the 3D projection space. A correction for these 'lost' events was implemented as a global post-reconstruction scale factor, based on the overall fraction of lost events. Reconstructions from both motion correction methods were compared with a motion-free reference scan of the same phantom. Motion correction produced a marked improvement in image clarity and reduced errors with respect to the reference scan. LOR rebinning with global loss correction was found to be more accurate than the MAF method
Laser Beam Induced Current measurements on Dye Sensitized Solar Cells and thin film CIG(S,SE)2 modules

Calculating the efficiency of a solar cell depends on a precise knowledge of its area. Indeed, the photoresponse uniformity is essential to improve the manufacturing process. In this work we report on Laser Beam Induced Current measurements performed on CIG(S,Se)2 modules and Dye Sensitized Solar Cells. These measurements, performed via a green and a red HeNe lasers both operating at an optical irradiance of 1 Sun, allowed to obtain an accurate photoresponse map of the specimens and highlighted the non-uniformities with a spatial resolution of 400 µm and 80 µm, respectively.
