Absorption, reflection and transmission are amplified using sodium atomic medium with parameters of control fields and incident angle $$\theta$$ . Investigation over the normalization condition reveals that $$|T|+|R|+|A

Metaphors provide the opportunity to make sense of our experiences and share them with others. The current research qualitatively examined interviews with adoptive parents who had adopted through intercountry or private adoptions. Throughout their interviews, each participant used at least one metaphor in describing their experiences of adopting and raising their child. Overarchingly, the metaphor of “Adoption is a journey” encapsulated parents’ experiences. To demonstrate the journey, parents used metaphors to describe the past, present, and future. Metaphors of the past focused on their child's trauma and the origin of how the child came to join their family. Metaphors used to describe the present were challenge metaphors, including child's behaviors and finding support, coping metaphors, and balance metaphors. Lastly, metaphors of the future included guiding and commitment metaphors. In addition to metaphors, parents used symbolic rituals to connect their children with their past and current family. From metaphors, we offer several practical implications for postadoption intervention. First, interventions should be developed to meet participants where they are. Second, interventions should focus on the overall picture of adoption, as parents make sense of their past experiences and their ideals about the future. Lastly, services should focus on tools, not fixes.

In this paper, a family of new entanglement-assisted quantum error-correcting codes (EAQECCs) is constructed from constacyclic codes with length $$n=\frac{q^2+1}{a}$$ by giving a new method to select defining sets, where $$a=m^2+1$$ , $$m>2$$ is even and q is an odd prime power with $$a\mid (q\pm m)$$ . It is worth pointing out that those EAQECCs are entanglement-assisted quantum maximum distance separable (EAQMDS) codes when $$d\le \frac{n+2}{2}$$ . All of them are new in the sense that their parameters are not covered by the previously known ones. Moreover, they have minimum distance larger than $$q+1$$ . Compared with the codes with the same length listed in Table 1, our codes have larger minimum distance.

Bu çalışmada. sağ yan fonksiyonları birinci değişkenlerine göre singülerliğe sahip ve başlangıç koşulu homojen olmayan Riemann-Liouville kesirli diferansiyel denklemlerinin bazı sınıfları göz önüne alınmıştır. İlk önce, bu başlangıç-değer probleminin bir lokal sürekli çözümünün varlığını hangi koşular altında gerçekleştiği kısaca ifade edilmiştir. Daha sonra ise, sırasıyla Krasnosel’skii-Krein, Kooi, Roger ve Banaś-Rivero tiplerinde teklik teoremleri ortaya çıkarılmıştır. Bu teoremler daha önceden elde edilen sonuçları geliştirken, bu teoremlerin ispatları için, daha önceden var olan teknikler Lebesgue uzaylarının araçları ile zenginleştirilmiştir., In this study, some classes of Riemann-Liouville fractional differential equations with right-hand side functions having a singularity with respect to their first variable and with a nonhomogeneous initial condition are considered. First, it is briefly stated that under which conditions the existence of a local continuous solution of this initial value problem occurs. Later, uniqueness theorems were developed in types of Krasnosel’skii-Krein, Kooi, Roger and Banaś-Rivero, respectively. These theorems improve the previously obtained results, and for their proofs pre-existing techniques are enriched by the tools of Lebesgue spaces.

We present an improved version of a torsionally oscillating resonant pipe viscosity sensor. The new design offers the possibility to sense both, viscosity and density independently and at the same time. The first version of the sensor allowed only sensing the viscosity-density product, where the two values were not separable without additional knowledge or measurements. For the new design, density sensitive structures were additionally implemented into the pipe system. These structures force the fluid to follow the torsional oscillation of the pipe, therefore, in this region the fluid influences the behavior of the resonant structure like an additional mass. This leads to a frequency shift which is mainly density dependent. Due to this behavior it is now possible to use a higher order model to extract both viscosity and density out of one single measurement. We present the newly introduced sensor design, compare it to the first sensor design, describe the additional density sensitive structures and explain how the sensor was designed and evaluated using the Finite Element Method (FEM). We show how different values of viscosity and density influence the resonance frequency and the damping characteristics of the sensor. To prove the concept, we apply a calibrated higher order model to the simulation results and provide a first accuracy estimation.

Power semiconductor devices have maximum junction temperature limits, but it is not straightforward to sense or infer temperature inside sealed devices in running converters. One method is to observe electrical behavior that is known to be temperature dependent. For example, in some gallium nitride (GaN) power semiconductor devices, the maximum slope of the device current at turn- on has been shown to reduce as the junction temperature increases. This article demonstrates the first noncontact overtemperature protection circuit for GaN power devices that exploits this effect and overcomes the complication that this inverse proportionality is affected by load current. A variant of a previously reported magnetic field “Infinity Sensor,” named after its figure-of-eight topology and high bandwidth (>200 MHz), measures di/dt . Using the sensor signal as the only input, a detection circuit finds peak di/dt , and a high-speed integrator derives instantaneous load current. The reference voltage for the decision-making part of the circuit is automatically adjusted as a function of load current, in order to counteract the dependence of di/dt on load current. Experimental results on a 400 V, 2 kW buck converter show the protection circuit successfully activating within ±5 °C of a preprogrammed junction temperature setting, independently of load current, for settings of 100, 120, and 140 °C.

To scale the ferroelectric random access memory (FeRAM) technology toward 28 nm or beyond, it is critical to develop stacked capacitor (with sufficient surface area) to allow good sense margin for the 1-transistor- 1-capacitor (1T1C) bit cell. Therefore, to enable 3-D integration in back-end-of-line (BEOL) process, it is essential to optimize the fabrication recipes in low-thermal budget ( 50 s) in low temperature (\sim 350 °C), the ferroelectric properties of HZO could be fully manifested. No degradation is shown in the remnant polarization ( ${P}_{r}$ ) under the optimized low-temperature process. Furthermore, the retention/endurance characteristics with different ${P}_{r}$ states were measured to determine the minimally required write voltage. Finally, the SPICE simulation is conducted to evaluate the sense margin of the projected 28-nm 1T1C array with stacked cylindrical capacitors using the measured ${P}_{r}$ drift behavior over time.

In this paper, we consider a typical continuous two dimensional $\mathcal {P}\mathcal {T}$ -symmetric Hamiltonian and propose two different approaches to quantitatively show the difference between the η-inner products. Despite the continuity of Hamiltonian, the η-inner product is not continuous in some sense. It is shown that the difference between the η-inner products of broken and unbroken $\mathcal {P}\mathcal {T}$ -symmetry is lower bounded. Moreover, such a property can lead to some uncertainty relation.

The objective of this paper is to examine in which way the use of the oral and written discourse in Julian Barnes’s novel The Sense of an Ending (2011) reflects, on the one hand, a social hierarchy based on classificatory cultural, intellectual, and educational competencies and resources and, on the other, dominance strategies and power relations developed among the principal actors. It will be investigated how trivial discussions and letters exchanged between friends are deployed in order to sustain or eliminate control over the other(s) and indicate status positions. The proposed methodological framework of analysis is founded on Bourdieu’s approach to cultural capital, according to which cultural preferences are markers of social stratification, while highbrow aesthetic judgment is both a means to, and a stake in, upward social mobility. Foucault’s theory of a “decentralised” and ubiquitous power, dispersed at all levels and defined as an action directed to other people’s actions, will also be applied.

This article features a case study about the author’s two research encounters with an emotionally reluctant male participant who seemed to experience discomfort and who also made the author feel uncomfortable. To make sense of this mutual experience of discomfort, the article explores the intersubjective exchange between the interviewer and her participant through the application of the psychoanalytic concepts of ‘defence’ and ‘(counter-)transference’. The article argues that the mutual discomfort resulted from the participant’s desire to perform masculinity in ways that fit the Vietnamese hegemonic masculinity and from the researcher’s inability to identify this desire during the interviews. By locating the participant’s engagement with hegemonic masculinity within the sociocultural context of contemporary Vietnam, and investigating the resulting discomfort, the article demonstrates how applying a psychosocial approach to a research relationship can be fruitful. It shows that such an approach can help researchers acquire unexpected insights into the psychological and social meanings of research encounters beyond an analysis of just the text, thus adding to methodological discussions about qualitative interviews.

The main research question is based on the thesis that harmonization of personal income taxation in the European Union is, on the one hand, not possible and, on the other hand, not advisable Harmonization of income taxes is much more difficult than harmonization of indirect taxes from the practical, technical and legal perspective and is a result of: (a) when creating the Treaty of Rome it was decided that direct taxes would not have a notable impact on the operations of the internal market, and that approach led to a lack of appro-priate regulations, especially in the area of personal income taxes; (b) income taxes, as forms of direct taxation are an important tool for fiscal policy that affects social and eco-nomic activities and it is difficult for politicians to abandon this tool for managing national policies; (c) directives requiring the formulation of direct tax harmonization must be agreed upon with a majority vote in the national Assemblies (Parliaments), which leads to a lack of consensus on desired aims, costs and benefits, procedures; (d) progress in direct tax harmonization creates an aura of challenges to the tax independence if nations and leads to entrenchment of state and elite positions; (e) EU States Mmember states have different rules for remunerating employees, setting incomes from retirement funds and affecting the structure of income-generating costs and expenditures that reduce the tax base.

In this article, the stochastic Hirota–Maccari system forced in the Itô sense by multiplicative noise is considered. We just use the He’s semi-inverse method, sine–cosine method, and Riccati–Bernoulli sub-ODE method to get new stochastic solutions which are hyperbolic, trigonometric, and rational. The major benefit of these three approaches is that they can be used to solve similar models. Furthermore, we plot 3D surfaces of analytical solutions obtained in this article by using MATLAB to illustrate the effect of multiplicative noise on the exact solution of the Hirota–Maccari method.

PurposeThe paper concludes with showing that in the most optimistic scenario, end-of-life (EOL) batteries will account for 86% of energy storage for wind and 36% for solar PV in 2040.Design/methodology/approachWith the growing demand for electric vehicles (EVs), the stock of discarded batteries will increase dramatically if no action is taken for their reuse or recycling. One potential avenue is to reuse them as energy storage systems (ESS) to mitigate the intermittent generation of renewable energy such as solar PV and wind.

At the high power switching circuit's applications, when the harmonic distortion is harmful, a multi-level diode clamped inverter is useful, especially when reduced total harmonic distortion and high power are desired. But when the levels get a rise, number of semiconductors are also rising, which leads to many problems such as increasing cost, losses, installation area, and total harmonic distortion. Many researchers have tried to find solutions to these problems. In this sense, this paper focuses on: a) build a new structure of five level diode clamped inverter. b) Increase the efficiency of the inverter by reducing the number of switches. c) Reduce the total harmonic distortion. The theoretical calculation and simulation results are performed for five level diode clamped inverter by MATLAB/ SIMULINK. http://dx.doi.org/10.30572/2018/kje/090414

Under Canadian constitutional law, state neutrality acts as an implicit organizing principle for the relations between the state and religions. Neutrality, however, is a polysemic word: conceptions of neutrality vary. Competing versions of neutrality feature in the decisions of Canadian courts. This is starkly evident in decisions that originate from Quebec, where judges have harboured divergent views of neutrality on matters such as the reciting of prayers in town hall meetings or the teaching of religious diversity in schools. This article analyses how the Canadian Supreme Court has manoeuvred through competing conceptions of state religious neutrality. Initially divided, the Court seems to have eventually opted for a type of neutrality that allows the state to recognize the existence of religions in laws and policies, but that also prevents it from indoctrination and from arbitrating between competing viewpoints within religions. This view of neutrality, I argue, is consistent with the principle of multiculturalism and with the Court’s characterization of a ‘free and democratic society’, as this notion is understood in Canada.

In this article, we tackle the problem of using survival signatures to compare heterogeneous systems with ordered components. The scenarios where systems have the same size and those where they have different sizes are studied. Several sufficient conditions comparing two system lifetimes in the sense of the usual stochastic order are provided. Several numerical examples are presented to illustrate the main results.

It began, as with many good things, at a happy hour. Adam Cohen, a young assistant professor asked whether rhodopsins could be used to optically sense voltage. In the heady days of 2009, channel rhodopsin had just been unveiled as a voltage actuator in neurons. Adam had the insight to question whether rhodopsins could be run in reverse; could optical changes in a protein relay the cellular voltage state using light? This was one of the earliest lessons I learned under his mentorship, and the first piece of advice in this retrospective—turning a scientific question or statement on its head can be the basis for many fantastic research projects.

The aim of the article was the analysis of the factors that may affect on the sense of safety in local communities. The method applied in the article was a diagnostic survey using questionnaires as a technique and a questionnaire which was used as a tool for collecting the empirical data. The obtained data made it possible to solve the research problem (presented in the article) and to demonstrate, in an innovative way, the relation between factors such as: contact with relevant services, information campaigns, preventive measures and the elimination of people at risk of social pathologies as those that affect on the safety of the local community. The results of the research show that respondents are aware of the presence of certain factors in their local environment as well as see their impact on the functioning in the local community and they know about factors which have a significant impact on their sense of security in the context of functioning in the local community.

The growing demand for sustainable mobility and, consequently, also for a wider use of electrical energy in the transportation sector is posing serious challenges not only to onboard vehicle systems but also to the electrical network that allows the integration of more charging systems. These systems are often requested to provide power in a short time (fastcharging), and this request is, unfortunately, mostly in the morning hours when the electrical network is already loaded, sometimes even very heavily. Consequently, future fastcharging stations are requested from one side to integrate energy generation systems (like photovoltaic) and storage systems to realize, when possible, a net-zero energy system and from the other side to provide advanced supporting functionality for the electric network, such as voltage control or load management to counteract the effects of the peak power requests when generation and storage are not present and/or not enough. In this sense, a smart transformer could present an optimal solution offering low-voltage (LV) and medium-voltage (MV) dc distributions to supply several charging points with high efficiency and to integrate storage in a charging-park and coordinate charging, energy generation, and storage following a dispatchment plan.

The rapid and cost-effective quantitative characterization of broad-sense shale oil reservoirs is highly challenging due to the complex lithology and strong heterogeneity of the strata. In this paper, the pore structures and surface roughness of samples of various lithologies from a shale oil reservoir were studied using atomic force microscopy (AFM) and the open-source Gwyddion analytical software. The surface morphology was reconstructed both two-dimensionally and three-dimensionally using the AFM data for the mudstone, siltstone, and dolarenite in a broad-sense shale oil reservoir. The surface roughness was evaluated with respect to parameters such as the arithmetic average roughness, root mean square roughness, surface skewness, and kurtosis coefficient. The pores of various scales were quantitatively identified using the watershed algorithm. The samples were also evaluated using focused ion beam scanning electron microscopy for comparison, and the derived pore scales are consistent with those obtained from the AFM analysis. In conclusion, the utilization of AFM and open-source software provides a new easy-to-operate method, which can be widely applied to characterize the surface roughness and pore structures of unconventional oil and gas reservoirs.

In this paper, we study the self-assembly of rectangles in a non-cooperative, 3D version of Winfree's abstract Tile Assembly Model. We prove two results. First, we give the full details for the proof of a general construction for the efficient self-assembly of thin rectangles that was first reported by Furcy, Summers and Wendlandt (2019). This construction is non-cooperative and “just-barely” 3D in the sense that it places tiles at most one step into the third dimension. Second, we give a non-cooperative, just-barely 3D optimal encoding construction that self-assembles the bits of a given binary string along the perimeter of a thin rectangle of constant height.

In this paper, the variable order fractional derivative in the Heydari-Hosseininia sense is employed to define a new fractional version of 2D reaction-advection-diffusion equation. An efficient and accurate hybrid method based on the shifted orthogonal Bernoulli polynomials and radial basis functions is developed for solving this equation. The presented method converts solving the problem under consideration into solving a system of algebraic equations. The applicability and accuracy of the proposed method are investigated by solving some numerical examples.

Weiss and Camnitzer discuss his ideas about the transformative potential of art in education; his experiences in and thoughts about Cuba and Cuban art; his “Uruguayan Torture” series of prints, and his thoughts about productive anarchy.

In this article, an L-shaped tunnel field-effect transistor (LTFET)-based one-transistor dynamic random access memory (1T DRAM) with SiGe storage region was demonstrated through 2-D TCAD simulations. The SiGe storage is utilized to boost not only the sense margin (SM) but also the retention time (RT) in comparison to the previously published TFET-based 1T DRAMs. The simulation results reveal that the LTFET 1T DRAM acquired the SM of $6.2~\mu \text{A}/\mu \text{m}$ with RT of 1.7 s when 50-nm gate length was adopted at 27 °C, whereas at 85 °C, the LTFET 1T DRAM attains the SM and RT of $5.1~\mu \text{A}/\mu \text{m}$ and 290 ms, respectively. Furthermore, the LTFET 1T DRAM still attains the RT of 1.3 s at 27 °C when the gate length is scaled down to 20 nm. Thus, LTFET 1T DRAM exhibits a better gate length scalability in comparison to the counterpart TFET-based 1T DRAMs. In addition, we observed that the impact of ion irradiation on the proposed cell exhibits almost the same SM before and after the ion strike.

In a conventional open bit-line scheme of DRAM, the edge subarrays (MATs) located at both ends of the cell array block contain alternated real and dummy bit-lines, unavoidably leading to an additional area overhead. To reduce the area overhead, one edge MAT can be eliminated by converting the dummy bit-lines of the other edge MAT into real bit-lines. This strategy causes the conventional bit-line sense amplifiers (BLSAs) in the MATs located at both ends of the cell array block to have a much smaller complementary bit-line capacitance than a true bit-line capacitance. Thus, the sensing operation of a conventional BLSA with this unbalanced bit-line capacitance experiences various problems: sensing voltage decrease, data flipping, and asymmetric equalization. To solve these problems, we propose a novel sensing circuit that can operate effectively even under unbalanced bit-line capacitance, thus suggesting the possibility of an open bit-line scheme without dummy bit-lines. Our proposed dummy-less open bit-line scheme can save approximately 4% of the array height. Compared with the conventional unbalanced BLSA, the proposed BLSA increases the sensing voltage by more than 100%, reduces the voltage peaks by 30% during the data transfer, and reduces equalization time by 1.2 ns in HSPICE Monte Carlo simulation.

This brief presents a 52–58 GHz power amplifier (PA) with constant output power across the entire band. A new topology based on the impedance transformation of transmission lines was adopted as the inter-stage matching network. Compared with the conventional 2-section LC matching topology, our approach reduced the matching loss by 1.5 dB at 54 GHz. Such topology made the design capable of operating at a frequency close to 80% of the unit-current-gain cut-off frequency ( $f_{T}$ ) specified by the device technology. Additionally, stacked-FET was adopted as the power stage for the output power enhancement in a broadband sense. Implemented in the commercially available 0.15- $\boldsymbol{\mu }\text{m}$ GaAs pseudomorphic high-electron-mobility transistor (pHEMT) process, the 2-stage PA demonstrated a small-signal gain of 14.7 dB, a saturated output power ( $P_{sat}$ ) of 18.6 dBm, and a maximum power-added-efficiency (PAE) of 18.2% at 54 GHz.

International relations have always been related to a particular sense of living together, both as a concept and as an academic field shaped by some practices of being-together. The question of how international relations perceive a way of living together (as being-together in a common space) has been addressed from the early forms of post-structuralist quests by trying to deal with the issues such as inside/outside, identity/difference, but has not been intensely focused on the issue of common and its alternative perceptions by approaching the fundamental relationship between the ontological status of being-in and being-together. In this article, with focusing on how a particular way of being-in-a-common is related to a certain ontology of international relations, I will utilize French philosopher Jean Luc Nancy’s re-writing of Heideggerian notion of Mitsein (being-with) in order to problematize the phenomenon of the international as an intermediate category that defines our meanings of living-together and our relationship with this world.

Approximate computing stands out in systems in which the simplicity must be above the demand for high precision and processing speed. It is the case of DNA systems, especially those based on the DNA strand displacement technique, which is naturally in a complex and noise-filled environment. In this sense, proposals for approximate DNA circuits implemented with an analog approach promise future disease diagnosis applications, for example. In this paper, we adapted a multiplication gate presented in the literature in order to reduce the influence of leak reactions. For this, we insert drain species after some time at the beginning of the process. Next, we built a DNA analog circuit using the multiplication gate with the extended addition and subtraction gates, proposed earlier, to solve a simple expression. The results showed that our modification significantly reduced the effects of leaks and the implemented circuit has an adequate accuracy with an acceptable error when their inputs species present median concentrations.

The spread of gambling addiction is one of the serious problems of modern society. Gambling addiction is a progressive disorder which is a complex formation and includes a syndrome of mental and physical dependence. A person involved in gambling creates grounds for inevitable failure: social disadaptation, coldness to relatives and social alienation; loss of what has been achieved in life; risk of losing livelihood; suicidal attempts; criminal behavior, etc. The negative social consequences demonstrate the need for more effective and comprehensive study in this area. The peculiarities of transformation of the value -and- sense sphere of personality in developing game addiction as well as in the process of rehabilitation still remain an insufficiently explored issue. This determines the relevance of our work. Objective. The article is devoted to the peculiarities of transformation of the value-and-sense sphere of gamblers undergoing rehabilitation program. Methods. Participants were 42 gambling addicts undergoing a rehabilitation program at the branches of the rehabilitation center “XXX” (Odintsovo, Moscow region and Omsk). The survey packet consisted of Zimbardo Personality Time Perspective; Life-Purpose Orientation Test by D.A. Leontiev; Self-Attitude Questionnaire by V.V. Stolin and S.R. Panteleyev; Rokeach Value Survey and the personal data questionnaire. Statistical methods (primary descriptive statistics, correlation analysis, Fisher’s F-criterion, Student’s t-distribution and the Wilcoxon signed-rank test) were used to process data. Results. In the course of the study, the hypothesis of a possible transformation of the value-and-sense sphere of gamblers towards a more adaptive one in the conditions of rehabilitation was tested and confirmed. The study found a connection between participation in the rehabilitation program and changes in the time perspective of the participants’ positive future. The research also revealed an increase in the level of life meaningfulness and self-esteem and a decrease in the level of self-blaming. The tests showed the shift of value from material support to self-development and self-acceptance. Scientific novelty. It was for the first time when the researchers made an attempt to study and compare to a great extent the characteristics of the value-and-sense sphere of gamblers before and after rehabilitation. Practical significance. The results can be taken into account to plan treatment and rehabilitation measures as well as to prevent gambling addiction.

The Internet of Things (IoT) is one of the most prominent technologies, which primarily deals with inter-connecting, controlling and managing digital and electronic devices that are connected to the internet through an IP address. The evolution of high speed network technologies like Long Term Evolution (LTE) and upcoming 5G network technology had already led the path to simulate the whole electronic and digital services and applications at the finger tips. However, the physically challenged people especially the visually challenged people could not utilize the whole of technologies and yet this makes them feel more distressed about themselves. Braille is vital for communication and education purposes for the visually challenged persons. The solution for this problem is to handle the distance between the obstacle and the person. The aim of this project is to develop a smart cap, which has the distance measurement system. Device that will be useful who are visually impaired. This device primarily allows its user to scan their surroundings for obstacles. The device which has sensors (Lidar) for detecting the obstacles. It is connected to the smart phone via Bluetooth or any other means. It will notify and guide the user if there is any obstacles stairs or potholes around. It is based on ToF (Time of Flight) principle and integrated with unique optical and electrical designs, so as to achieve stable, precise, high sensitivity and high-speed distance detection. Features: Operating Range: 0.3-12m maximum operating range at 10% reflectivity. "Share live location" feature allows the user's can share their live location to their personal contacts.

A convex sweeping process is considered in a separable Hilbert space. The majority of works on sweeping processes use the Hausdorff distance to describe the movement of the convex set generating the process. However, for unbounded sets the use of the Hausdorff distance does not always guarantee the fulfilment of conditions under which a solution exists. In the present work, instead of the Hausdorff distance we use the $$\rho $$ -excesses of sets. These excesses are subjected to positive Radon measures depending on $$\rho $$ . We prove the existence of right continuous BV solutions and establish their dependence on single-valued perturbations depending only on time. The results we obtain are applied to prove the theorems on existence and relaxation of extremal right continuous BV solutions of a sweeping process with multivalued perturbations. Some results on absolutely continuous solutions are derived as corollaries.

Most of the studies that can be found in the literature for analysing self-consumption systems with storage focus on global self-consumption and self-sufficiency indices and it may be very difficult to define the role of the array power and battery. In this sense, a new approach to analysing this type of systems is provided where direct and battery self-sufficiency and self-consumption indices are defined. The latter represent the direct photovoltaic self-consumed energy and the one provided by the battery. New direct and battery ZEB points are also presented. Furthermore, this type of system is generally analysed using complex 3D plots. Therefore, a new and intuitive 2D contour tool is provided: the iso self-consumption curves. The new approach has been applied to three households located in Spain. Results show that it may be reached a global self-sufficiency of 50% considering array powers and rated capacities below 3.5 kWp and 1 kWh, respectively, where direct and battery self-sufficiency indices may reach 40% and 10%, respectively. This new method together with the graphical tool may help not only to analyse this type of system but to properly size the array power and the rated capacity from either an energetic or profitability approach.

Ultra-compact wireless implantable medical devices are in great demand for healthcare applications, in particular for neural recording and stimulation. Current implantable technologies based on miniaturized micro-coils suffer from low wireless power transfer efficiency (PTE) and are not always compliant with the specific absorption rate imposed by the Federal Communications Commission. Moreover, current implantable devices are reliant on differential recording of voltage or current across space and require direct contact between electrode and tissue. Here, we show an ultra-compact dual-band smart nanoelectromechanical systems magnetoelectric (ME) antenna with a size of 250 × 174 µm2 that can efficiently perform wireless energy harvesting and sense ultra-small magnetic fields. The proposed ME antenna has a wireless PTE 1–2 orders of magnitude higher than any other reported miniaturized micro-coil, allowing the wireless IMDs to be compliant with the SAR limit. Furthermore, the antenna’s magnetic field detectivity of 300–500 pT allows the IMDs to record neural magnetic fields., Wireless implantable medical devices (IMDs) are hamstrung by both size and efficiency required for wireless power transfer. Here, Zaeimbashi et al. present a magnetoelectric nano-electromechanical systems that can harvest energy and sense weak magnetic fields like those arising from neural activity.

This article reviews the history of thermal aging studies of rotating machine insulation, describes how the thermal classes are determined, and identifies some issues with the process that often are not fully understood.

In this article, we present a fiber Bragg grating (FBG) based 6-D force/torque (F/T) sensor that can be mounted on robot joints for the detection of comprehensive F/T information. The sensor is designed based on a new concept of multilayer measurement in which the elastic structure is divided into four layers. A single optical fiber inscribed with 12 FBGs is symmetrically attached to the elastic structure to sense F/T-induced strains by means of differential measurements. Because of the mechanical decoupling function of the structure and the reasonable arrangement of the FBG sensing elements, the designed sensor possesses a great advantage of low cross coupling compared with the existing 6-D F/T sensors, which simplifies the calibration and maintenance of the sensor. Calibration experiments demonstrate high resolutions of 7.8 N·mm, 7.2 N·mm, 15.8 N·mm, 0.0067 N, 0.0066 N, and 0.0825 N within the range of ±1.56 N·m, ±1.56 N·m, ±1.56 N·m, ±10 N, ±10 N, and ±25 N for the detection of Mx, My, Mz, Fx, Fy , and Fz , respectively. Dynamic performances of the designed sensor have been evaluated in comparison with a commercial F/T sensor.
