The Coil Misalignment Model of Inductively Coupled Wireless Power Transfer System: Mutual Inductance Analysis and Transfer E-ciency Optimization

A novel means of optimizing transfer e-ciency of Inductively Coupled wireless power transfer (WPT) system is presented for the flrst time. In the applications envisaged, such as electric vehicles and biomedical implants, generally the receiving coil is laterally and angularly misaligned from the transmitting coil. The numerical solution of mutual inductance between the two coils is derived and simulation result shows there is a partial optimal solution in the ranges of lateral and angular misalignments. The bigger is mutual inductance, the higher transfer e-ciency is. The novel means presented in this study allows the coil to be removable and rotatable for achieving bigger mutual inductance and optimizing transfer e-ciency. Finally the experimental results show the means is e-cient and greatly improves the transfer e-ciency. If the transfer distance is 15cm and there is no lateral misalignment, the transfer e-ciency can be improved about from 38.6% to 60.5% by turning the transmitting coil to make the tilt angle varied from 0 to …=4. This introduced technique can be widely applied to WPT system to optimize the transfer e-ciency.
Biodiesel production from waste cooking oil using a new heterogeneous catalyst SrO doped CaO nanoparticles

Biodiesel production from waste palm cooking oil (WPCO) was studied. Calcium oxide with a strontium ion additive (Sr-CaO) was employed as a catalyst in transesterification reaction of used palm oil with methanol. The Sr-CaO was synthesized by co-precipitation method between SrCl2 and Ca(NO3)2, then calcined at 900°C for 5 h. The catalyst was characterized by using thermo-gravimetric analysis (TGA), X-ray diffraction (XRD), Scanning electron microscope (SEM), and Fourier transform infrared spectrometer (FT-IR). The morphology and elements content of Sr and Ca in the catalyst were confirmed by SEM-EDX. The approximate catalyst diameter is 12.6±5.9 µm. The highest conversion was 99.33% (the reaction time 3 h, 5%w/w catalyst, methanol to oil molar ratio 9:1 and reaction temperature 80°C). The catalyst can be used up to the sixth cycles with a good yield. The synthesized biodiesel meet the requirement of standard biodiesel (EN 14103 and ASTM D445). These findings suggest that calcium oxide with a strontium ion additive (Sr-CaO) is an effective renewable biodiesel catalyst.
CRP Serum Levels Are Associated with High Cardiometabolic Risk and Clinical Disease Activity in Systemic Lupus Erythematosus Patients

Systemic lupus erythematosus (SLE) patients have a higher frequency of cardiovascular risk factors such as high C-reactive protein (CRP) levels than the general population. CRP is considered a cardiovascular disease marker that could be related to SLE clinical disease activity. This study aimed to assess the association between CRP with cardiometabolic risk and clinical disease activity in SLE patients. A comparative cross-sectional study was conducted in 176 female SLE patients and 175 control subjects (CS) with median ages of 38 and 33 years, respectively; SLE patients were classified by the 1997 SLE-ACR criteria, and the clinical disease activity by the Mexican-SLEDAI (Mex-SLEDAI). CRP and lipid profile (triglycerides, cholesterol, HDL-C, and LDL-C) were quantified by turbidimetry and colorimetric-enzymatic assays, respectively. SLE patients had higher CRP levels than CS (SLE: 5 mg/L vs. CS = 1.1 mg/L; p < 0.001). In SLE patients, CRP levels ≥ 3 mg/L were associated with a higher risk of cardiometabolic risk status assessed by LAP index (OR = 3.01; IC: 1.04–8.7; p = 0.04), triglycerides/HDL-C index (OR = 5.2; IC: 2.1–12.8; p < 0.001), Kannel index (OR = 3.1; IC: 1.1–8.1; p = 0.03), Castelli index (OR = 6.6; IC: 2.5–17.8; p < 0.001), and high clinical disease activity (OR = 2.5: IC: 1.03–6.2; p = 0.04; and β coefficient = 5.8; IC: 2.5–9.4; R2 = 0.15; p = 0.001). In conclusion, high CRP levels were associated with high cardiometabolic risk and clinical disease activity in SLE patients.
Evolutionäre Algorithmen zur Parameteroptimierung

Evolutionary Algorithms (EA) are stochastic optimization methods following the example of natural evolution. A set of points in the search space is treated as a population of individuals in an artificial environment. By modelling recombination, mutation and selection new generations of points evolve which are likely to be better than their ancestors on average. EA are universal and robust methods. This article summarizes the model of natural evolution that EA are based on, preceded by a short overview of parameter optimization terms. Finally, the two main instances of EA, Genetic Algorithms and Evolution Strategies, are introduced and discussed
Automaticity and Executive Abilities in Developmental Dyslexia: A Theoretical Review

Cognitive difficulties are well documented in developmental dyslexia but they present a challenge to dyslexia theory. In this paper, the Model of the Control of Action is proposed as a theoretical explanation of how and why deficits in both automaticity and executive abilities are apparent in the cognitive profiles of dyslexia and how these deficits might relate to literacy difficulties. This theoretical perspective is used to consider evidence from different cognitive domains. The neuroanatomical underpinnings of automaticity and executive abilities are then discussed in relation to the understanding of dyslexia. Links between reading, writing, and executive function are considered. The reviewed evidence suggests that dyslexia theory should consider an interaction between procedural learned behaviour (automaticity) and higher-order (executive) abilities. The capacity to handle environmental interference, develop and engage adaptive strategies accordingly, and plan actions all require interactions between the cerebellum and the prefrontal cortex (PFC). Difficulties in these areas might explain both impairments in the cumulative development of literacy skills in childhood and general task management in everyday life in adulthood. It is suggested that improved measures are required to assess this cerebellar–PFC interaction and to allow early identification of future literacy difficulties, allowing implementation of timely interventions and reasonable adjustments.
COMPARISON OF GA AND LQR TUNING OF STATIC VAR COMPENSATOR FOR DAMPING OSCILLATIONS

Static VAR Compensator (SVC) is added to the excitation system of a generator in order to enhance damping during low frequency oscillations. In this article Linear Quadratic Regulator (LQR) tuning approach and Genetic Algorithm (GA) are used to obtain supplementary controller parameters for oscillation damping. The performances of SVC without controller, SVC with LQR controller and SVC with GA controller are compared. Eleven bus two area four machine system is used for the study. The performance of the GA controller is found to be better than the LQR controller and without controller under different operating conditions. A comparison between the effect of SVC alone and the proposed GA and LQR is made.
Intelligent Fingerprint-Based Localization Scheme Using CSI Images for Internet of Things

Fingerprint-based indoor localization methods have become an important technology because of their wide availability, low hardware costs, and the rapidly growing demand for location-based services. However, it is low precision of positioning and time-consuming for retraining the model when the fingerprint database has changed with new input samples. In this paper, we propose a novel intelligence localization scheme utilizing incremental learning without retraining models based on channel state information (CSI), namely ILCL. CSI phase data are extracted through a modified device driver, and we convert them into CSI images, which are the input to a convolutional neural network for training the weights in the offline stage. The estimated location is obtained by a probabilistic method based on a broad learning system (BLS) that can continue to train rapidly on new input data in the online stage. The ILCL architecture can be characterized as “deep” and “broad” and can further extract features. Experimental results confirm the superiority of ILCL compared with five existing algorithms in two real-world indoor environments with a total area is over 200 ${m}^{2}$.
Adaptive Capacitor Charging Circuit With Simplified Configuration for Efficient Piezoelectric Energy Harvesting

In this study, we present an adaptive capacitor charging circuit for efficient piezoelectric (PE) energy harvesting (EH), which simplifies the configuration for powering wireless sensor network (WSN) nodes. In the circuit, the PE harvester directly charges the storage capacitor through the rectifier, eliminating the energy loss in the dc–dc converter of conventional EH circuits. An adaptive control circuit is designed to optimize the average charging power. Theoretical analysis shows that the optimal average power of the novel circuit varies from 81.4% to 86.5% of the maximum power of the conventional EH circuit, without considering the power dissipation in the dc–dc converter. Moreover, the power losses of both the proposed and conventional circuits are estimated. When the excitation level is low, the net harvested power of the proposed circuit can be enhanced to as high as 180% of that of the conventional circuit. The experimental results validate that the power transferred to the load is increased by adopting the proposed interface. It is also proved that the circuit is adaptive to different harvesters and excitation conditions. In addition, the area of the proposed circuit is reduced, allowing it to be easily integrated into the WSN nodes.
APPLICATION OF LIBERA BRILLIANCE SINGLE PASS AT NSRL LINAC BPM SYSTEM

Libera Brilliance Single Pass is a digital beam position processor with capabilities of single pass position measurement. This device can be used on the stripline beam position monitor (BPM) of the linac and transfer lines on light sources as well as injector system for the FELs. The linac of Hefei light source (HLS) was equipped with 2 stripline beam position monitors, which will be increased to 20 BPMs after upgrading. The existing BPM electronics were the homemade electronics with logarithm detector. To enhance the functionality of the BPM system, the Libera Brilliance Single Pass is employed to replace the existing BPM electronics. The newly buying devices have made test of characterization. The mapping of stripline BPM is made on a workbench with Libera Brilliance Single Pass. The beam position is tested at linac using Libera Brilliance Single Pass. And the results of these measurement performed on Libera are reported to compared to measurements with the linac’s existing BPM electronics. INTRODUCTION Starting mid of 2009 the HLS will be upgraded, the energy of the storage ring will remain 800MeV, the emittance will be decreased, and the energy of the linac will be improved from 200MeV to 800MeV. The electron beam position monitor that was installed before did not meet the resolution and stability requirements of the new linac. Therefore it was decided to equip the new HLS linac with a completely new BPM-system. 20 stripline beam position monitors will be used for measurement and control of the beam trajectory. Because the Libera Brilliance Single Pass has high performance [1, 2], the Libera Brilliance Single Pass will be used to replace the existing BPM electronics. In order to show good performance in the future linac, Libera Brilliance Single Pass has to be carefully tested. In the following sections, the laboratory tests are performed, the mapping of stripline BPM is made, and several tests are made at HLS linac. LABORATORY TEST OF LIBERA BRILLIANCE SINGLE PASS The laboratory testing block diagram of Libera Brilliance Single Pass is shown in Fig.1. An arbitrary waveform generator produces two synchronous trigger signals with 50Hz repetition rate, one of them is fed into the Libera Brilliance Single Pass as an acquisition trigger signal while the other is fed into the pulse generator to generate pulses. The variable attenuator controls the amplitudes of the input signal to simulate different beam charges. And the pulses are fed into 4 channels of Libera Brilliance Single Pass through a 4 way power splitter. Figure 1: Laboratory test diagram of Libera Brilliance Single Pass To simulate the stripline signal, the pulse generator generated a short pulse. There is a shot of pulse seen by oscilloscope shown in Fig. 2. The pulse width is 1.35ns, in order to simulate the new linac beam pulse which will be about 1ns width. And the repetition rate is 50Hz as triggered by the arbitrary waveform generator. The signal seen by Libera is practically the response of the 500MHz filter with the bandwidth of 10 MHz [1].
Uniformity, Experimentalism, and the Unfulfilled Promise of Differentiated Integration in EU Regulation of GMOs: Which Way Forward?

EU governance in the field of agricultural biotechnology, especially authorizations for commercial use and cultivation of genetically modified organisms (GMOs), has always been an exemplary field of intense policy controversies leading to regulatory impasses. Notwithstanding repeated attempts to improve the functioning of the regime, the longstanding problems with insufficient democratic legitimacy of EU-level GM product approvals in comitology decision making have persisted, affecting the overall profile of the policy. This paper appraises the most recent reform of the GMO regime through a case study of the implementation of the Opt-out Directive 2015/412, which returned powers over GMO cultivation to the national level, from the perspective of differentiated integration (DI) in relation to other regulatory approaches, namely experimentalist governance (XG) and uniform regulation (UI). In order to do so, the paper addresses the conceptualization of the GMO regime, its successes and pitfalls, the origins of the DI reform, and national implementation in six Member States. The regulatory appraisal of the impact of the reform on the accommodation of diversity within the EU is carried out through the lens of the functioning of the Internal Market and GMO approvals through the comitology voting system. The paper establishes that the DI approach introduced by the 2015 Opt-out Directive failed to effectively foster accommodation of diversity in the GMO regime. It argues that this was due to the atypical mode of DI which was introduced in the system, and lack of exploitation of the opportunities offered by XG within the GMO regime. The paper shows that the reform reinforced asymmetries between Member States and did not fully address key problems of the GMO regime, including effective deliberation in comitology committees, pertinent national-level issues, and the need to revise the regulation in view of development of New Plant Breeding Techniques (NPBTs). Finally, the paper outlines three possible scenarios in the present situation. It argues that the most promising scenario would involve a combination of more radical DI and more extensive use of XG, including a complete return of decision-making powers over cultivation to the Member States and opening up debates about GMO authorizations to socio-economic and ethical-cultural factors beyond scientific risk assessment.
The Influence of Process Parameters on the Mechanical Properties of Friction Stir-Welded Dissimilar Aluminium Alloys AA2219 and AA7068

A practical solution is friction stir welding (FSW) of heterogeneous alloys in industrial applications. The welded joint’s mechanical strength has been improved by combining two different alloys (AA2219 and AA7068). The focus of this study was on friction stir-welded heterogeneous metals’ microhardness and material properties. It is possible to work with either hot or cold aluminium alloy, as it is heat treatable. Revitalizing and precipitation hardening follow the heat treatment. The welded joints’ hardness was assessed in several locations. Different joints’ tensile characteristics are compared. According to the stress-strain curve, the FSW settings’ mechanical properties were spread throughout the material flow. In terms of tool profiles, the cylindrical threaded profile is critical. One-third of the efficiency is due to it. A 195 MPa strength was reached in the cylindrical threaded pin profiled tool. In a new study, researchers discovered that cylindrical threads have faster rotary motion, transversal, and D/d speeds. The cylindrical threaded tool provided the highest tensile strength and was superior to other materials. This phase of the material characterization included measurements of tensile strength and hardness.
Palliation in Gallbladder Cancer: The Role of Gastrointestinal Endoscopy

Simple Summary Gallbladder cancer is burdened by poor prognosis, and palliation often represents the best option. Endoscopy plays a crucial role in the management of cholangitis, jaundice, gastric outlet obstruction, and pain. The aim of this study is to perform a review of the literature to assess the role of endoscopy in the palliative therapy of advanced gallbladder malignancy. Abstract Gallbladder cancer is a rare malignancy burdened by poor prognosis with an estimated 5-year survival of 5% to 13% due to late presentation, early infiltration of surrounding tissues, and lack of successful treatments. The only curative approach is surgery; however, more than 50% of cases are unresectable at the time of diagnosis. Endoscopy represents, together with surgery and chemotherapy, an available palliative option in advanced gallbladder cancers not eligible for curative treatments. Cholangitis, jaundice, gastric outlet obstruction, and pain are common complications of advanced gallbladder cancer that may need endoscopic management in order to improve the overall survival and the patients’ quality of life. Endoscopic biliary drainage is frequently performed to manage cholangitis and jaundice. ERCP is generally the preferred technique allowing the placement of a plastic stent or a self-expandable metal stent depending on the singular clinical case. EUS-guided biliary drainage is an available alternative for patients not amenable to ERCP drainage (e.g., altered anatomy). Gastric outlet obstruction is another rare complication of gallbladder malignancy growing in contact with the duodenal wall and causing its compression. Endoscopy is a less invasive alternative to surgery, offering different options such as an intraluminal self-expandable metal stent or EUS-guided gastroenteroanastomosis. Abdominal pain associated with cancer progression is generally managed with medical treatments; however, for incoercible pain, EUS-guided celiac plexus neurolysis has been described as an effective and safe treatment. Locoregional treatments, such as radiofrequency ablation (RFA), photodynamic therapy (PDT), and intraluminal brachytherapy (IBT), have been described in the control of disease progression; however, their role in daily clinical practice has not been established yet. The aim of this study is to perform a review of the literature in order to assess the role of endoscopy and the available techniques in the palliative therapy of advanced gallbladder malignancy.
Curved micromachined ultrasonic transducers

Capacitive micromachined ultrasonic transducers (cMUTs) have recently emerged as an alternative to traditional piezoelectric ultrasonic transducers. They have demonstrated competitive image quality, increased bandwidth and the potential for integrated on-chip electronics. For a variety of reasons, the cMUT fabrication process has limited initial cMUT array prototypes to high frequency, flat linear or phased array designs. However, Sensant has developed a straightforward method for the manufacture of curvilinear cMUT probes. This paper outlines the modeling and cMUT design strategies, describes relevant process steps, and details the manufacturing challenges associated with the curving and packaging of a cMUT. The paper concludes with measured results, including time and frequency domain impulse response plots and phantom and in vivo images from a fully packaged cMUT array with a center frequency of 4 MHz and a radius of curvature of 40 mm, parameters typical of an abdominal imaging probe.
Dispenser printed electroluminescent lamps on textiles for smart fabric applications

Flexible electroluminescent (EL) lamps are fabricated onto woven textiles using a novel dispenser printing process. Dispenser printing utilizes pressurized air to deposit ink onto a substrate through a syringe and nozzle. This work demonstrates the first use of this technology to fabricate EL lamps. The luminance of the dispenser printed EL lamps is compared to screen-printed EL lamps, both printed on textile, and also commercial EL lamps on polyurethane film. The dispenser printed lamps are shown to have a 1.5 times higher luminance than the best performing commercially available lamp, and have a comparable performance to the screen-printed lamps.
Effect of Moisture Exchange Caused by Low‐Temperature Annealing on Device Characteristics and Instability in InSnZnO Thin‐Film Transistors

Thin‐film transistors (TFTs) in practical operations are inevitably impacted by moisture and temperature. An investigation on the joint effect of environmental moisture and working temperature on device characteristics and instability is becoming necessary. However, few related studies have been performed. In this work, a low‐temperature (LT) annealing in air is proposed to simulate the working conditions of TFTs in display applications. The effect of moisture exchange caused by LT annealing on device characteristics and instability of InSnZnO (ITZO) TFTs is systematically investigated. Combined with X‐ray photoelectron spectroscopy analysis, TCAD design simulation, and the measurement of relative humidity (RH) change on the device surface, a model considering water diffusion and water ionization is proposed. The negative shift of the transfer curve is attributed to the extra electrons released from the water ionization and the positive‐bias‐stress‐induced instability is mainly attributed to the generation of interstitial/substitutional hydrogens and aggregation of hydrogen ions at the backchannel. The temperature and the RH on the device surface jointly determine the moisture diffusion direction. Furthermore, the model is verified by an LT vacuum annealing. The results and the model will be beneficial for the further reliable design of ITZO TFTs in commercial applications.
Isolated switched-boost push–pull DC–DC converter for step-up applications

A high voltage ratio DC–DC converter is proposed which is comprised of four stages. First, an impedance network along with a switching network have been used to boost the input voltage. The boosted voltage waveform is then followed by an isolation transformer to provide another degree of freedom and obtain higher boost ability. Finally, a voltage multiplier rectifier is utilised to rectify the secondary voltage of the transformer. No switching dead-time is required, which increases the reliability of the converter. The proposed converter benefits from the continuous input current. Besides, a comparison with the existing step-up topologies indicates that the number of passive elements and hence the weight and size have been reduced. The operating principles were analysed and the experimental tests on a 260 W prototype reveal that a high efficiency above 91% can be achieved.
