Machine-washable and breathable pressure sensors based on triboelectric nanogenerators enabled by textile technologies

Utilization of textile's triboelectric effect to realize the perception of pressure is of great interest for self-powered wearable electronics that integrate seamlessly with smart fabrics. However, the challenges associated with rational material/device designs based on conventional textile structures and the lack of understanding of the mechanical circumstances experienced by textile devices hamper the further advancement of this technology. Here, textile pressure sensors based on triboelectric nanogenerators (TENGs) with machine washability and excellent breathability are manufactured by using machines to interlace robust Cu-coated polyacrylonitrile (Cu-PAN) yarns and parylene coated Cu-PAN (parylene-Cu-PAN) yarns via multiple textile industry compatible technologies for the first time, simultaneously achieving devices with stitched, woven, and knitted structures. TENG-based pressure sensors with different textile structures are investigated under as-fabricated conditions and after machine washing, and a relation is proposed between textile structure and the key characteristics of the sensors. The material/device designs, mechanical circumstances, manufacturing methods, etc., will affect the sensitivity, linearity, saturation trend and washability of the obtained sensors. Finally, a smart textile glove with stitched pressure sensors is made to demonstrate grip posture detection in various circumstances.

Performance Evaluation of Active Noise Control for a Real Device Casing

Reduction of noise generated by devices is an important problem, both in industrial environments where high sound pressure levels may damage hearing, and in households where the sound pressure level is usually moderate, but may cause discomfort and stress. Classically used passive methods often have poor performance for low frequencies. Alternatively, active control can be used to improve noise reduction in this frequency range. In the proposed approach, noise generated by devices may be reduced by controlling vibrations of the casing. The authors previously confirmed the performance of the proposed active control approach using a dedicated noise-canceling casing. Herein, we describe further development and application of the method to an off-the-shelf washing machine. Electrodynamic actuators were installed on four walls of the washing machine. The performance of the control systems was experimentally evaluated during the real spinning phase and the results are reported here.

Study of the Designed Washing Machine for Canning Industry

Nowadays industry uses special washing machines to wash the outer surface of cans, which can be jet, submersible and combined-type. These washing machines are quite energy-intensive and metal-consuming. A washing machine was designed in Mari State University, in which the objects cleaned gain eccentric motion and bubbling is created from the side of cylindrical cans. In order to identify the dependence of the cleaning quality on liquid activation using the air bubbling method, a number of factor-at-a-time experiments with a three-fold repeatability were performed at the outside of the washed objects. Special theoretical calculations were carried out to identify the limits of the drive wheel speed values aimed at studying kinematic parameters. The type of hyperbolic dependence of the wheel diameter on its rotation frequency is also determined.

Preparation of certified reference materials for cotton fabric’s dye transfer inhibition performance test of household washing machines

At present, many well-known brands of washing machines in the market are equipped with dye transfer inhibition washing procedures. However, there is no standardized sample available for the evaluation of the dye transfer inhibition washing procedure, and there is no comparability and access standard of the high-quality washing machine with the related functions. In this article, the certified reference materials for the evaluation of the dye transfer inhibition function will be prepared, which consist of certified reference material of white cotton fabric and that of dyed cotton fabric. The certified reference material of white fabric is made of bleached plain fabric, and that of dyed fabric is made with different reactive red dyes and dyeing processes. The size and manufacturing process of the whole set of standardized samples for the evaluation of dye transfer inhibition are selected and determined through experiments. The preparation of the standardized sample for the evaluation of dye transfer inhibition will improve the research and design of the functional washing procedure, which can better solve the pain point when dark and light clothes are washed together.

Water-spray washing technique as a purification process in the production of biodiesel

In order to meet the standards set for biodiesel after biodiesel production via transesterification, a purification process is necessary. For the purification process, the wet washing method is mostly recommended because it is well-known for its easy application and high efficiency. However, this method requires a large volume of water and takes a long time. Consequently, this study focuses on designing a washing machine that reduces the amount of water used and shortens the application time for the washing method. The spray washing technique, a type of the wet washing method, was used for this study with a focus on the following parameters: the volume of water to crude biodiesel, flow rate, and time. All conditions investigated in the basic standards of biodiesel. The pH value, density, and velocity were considered as the criteria to select the optimum conditions for the washing machine. The results indicated that a volume ratio of 0.8:1 (water:crude biodiesel) and a flow rate of 4 L/min for 0.5 min was the optimum condition of the water washing machine for biodiesel purification that meets the international biodiesel specifications.

Design and analysis of a novel variable flux spoke-type motor for washing machines

This paper deals with the design and analysis of a novel variable flux spoke-type motor (VFSM) for washing machines by focally considering the performance at the laundry and spin-drying operating modes. The key design goal is to obtain the high efficiency for the two operating modes. At the laundry mode, the ferrite and AlNiCo magnets are utilized together as the excitations to obtain a high magnetic loading, thus to obtain high torque and efficiency. At the spin-drying mode, the AlNiCo magnets are demagnetized by a pulse negative d-axis current to reduce magnetic flux density, thus to obtain low iron loss and high efficiency. The outer rotor structure with the spoke-type magnet configuration is utilized to enhance the high output performances. The D2L method is utilized to design the key parameters of the VFSM. To demonstrate the superiority of the designed VFSM, the electromagnetic characteristics are predicted by the finite element method (FEM). As a result, the volume size of the proposed VFSM is decreased by 19.4%, and the efficiency at the low-speed laundry mode is increased by 25.4%, when compared to the referenced commercial washing machine motor.

Why do we have to turn on this washing machine? The processes of domesticating household technology – situations of resistance

The author argues that resistance to new technology does not result from “technophobia” but rather from the fact that the new technological object is inscribed with new meanings and frameworks of action that may disturb the existing networks of practices, beliefs, and knowledge. Based on an analysis of 24 dyadic in-depth interviews and 52 individual in-depth interviews with people aged 47–91 living in Warsaw and Poznan (Poland), five sources of resistance to new domestic technologies were identified: (1) disruption of “flow” (Csikszentmihalyi 1990) – the pleasure resulting from a habitual and automatic action, the synchronization between the body and its material surroundings; (2) disruption of the “natural order of things” (the “mental map,” Kaufmann 2001) – a sense of security, durability or safety resulting from the stability of the spatial and material arrangement of the home (a sense that everything is in its place); (3) differences of standards and cultural ideals regarding acceptable practices, the quality of their performance, and their effect; (4) possible disturbance in relationships between members of the household; (5) beliefs about what is right, moral, or correct, as well as dissonances between different pieces of knowledge and beliefs, and between an opinion or belief and an embodied practice.

Mathematical modeling analysis and verification of vibration isolation parts of washing machine

Washing machines are used very frequently in everyday life. There have been many related studies on the vibration and noise of washing machines. The suspension system is an important vibration isolation component of the washing machine. Based on the Lagrangian equation, the dynamic model of the suspension system was established. The reliability of the model was verified by finite element simulation and experimental methods. Finally, this paper used a multi-objective optimization method to obtain optimal parameters of the washing machine and further to reduce the vibration level of washing machines.

Structural health monitoring and structural modifications of industrial building subjected to dynamic loading

A complex structural, static and dynamic review of an existing steel ceiling has been realised after two years of service and the completion of subsequent construction work. The construction work involved the reconstruction of a steel structure and structural modifications to the ceiling, which is part of the production hall. The construction work was realised in order to reduce the vibration response of the ceiling. The interior of the steel structure was supplemented by steel structural elements to share the load transfer of automatic washing machines. The structural behaviour of the ceiling was monitored before and after the modification. Accelerations of the ceiling were time-domain-monitored at specific locations. Measured data was transformed to the spectral-domain which is represented by power spectral densities.

The Year of Nostalgia

The Year of Nostalgia Alexander Weinstein (bio) I Nin found Dad frozen in the backyard. He wasn't trimming the hedges, just standing with his clippers in hand, staring at the bushes, she told me. Who knew how long he'd been like that, his body shivering. She'd put her hand on his back and guided him inside, where she made him a cup of tea. "You need to come home, Leah," she said. So I asked for another week off, got a reluctant yes, and headed back to Ohio. Our parents had done everything together, from puttering around the house to working in the garden. Dad would rake leaves, Mom would prepare lunch, and they'd sit in the living room in the late afternoon, reading e-books together. At night they'd stream a movie or go into town for dinner. They were that rare and beautiful couple, almost nonexistent nowadays, lifelong companions and best friends. Then, suddenly, there was only Dad, calling to tell us Mom was gone, making funeral arrangements without us, stern-faced through the service, telling everyone he was fine, just fine. I'd tried to help during the funeral—I cooked, cleaned the house, washed dishes, had planned to stay an extra week—but Dad pushed Nin and me away. Everything was fine, he told us, we girls should head home, no use staying at the house when we had our own lives to live. And after two days, he said we needed to go. What could we do? Nin left, driving the three hours back to her apartment in Toledo, and I flew back to Boulder, where Theo and the kids were waiting. Two weeks later, Nin called to tell me about finding Dad by the bushes. Nin picked me up from the airport. Besides the funeral, the last time we'd been home together was when I was finishing my grad degree and she was completing her freshman year as an undergrad. We'd argued about something dumb—an anthropology course she hated—I'd called her narrow-minded and she'd called me a patronizing bitch. After that we hadn't spoken for years. I was hoping grief might help us mend the distance, but when she picked me up, she was being her annoying self, asking me about my flight while simultaneously flicking her eyes to send texts in her contacts as she drove. "Uh-huh," she commented when I told her how the kids were doing, and laughed suddenly at a video in the corner of her eye. So, instead of continuing, I sat in the passenger seat hating how ADHD her generation was. "If Dad's got dementia," she said, "you're going to have to move home. I can't handle this alone." "He's just grieving," I said. I couldn't imagine uprooting everything and moving back to the Mid-west. We had our jobs, the kids' school, never mind living in suburban Ohio, a place Nin might be able to survive but not a place I wanted to return to. The house was a mess. Dad had let dishes pile up over the past weeks on tables, countertops, and bookshelves. Piles of laundry lay wherever he'd decided to get undressed. I ran the washing machine, [End Page 148] scrubbed dishes, and mopped the floors while Dad told us he didn't need our help. Later that evening, we found him in the basement, standing by the water heater for some reason only he understood. I led him back upstairs and got him in bed while Nin mixed us drinks from a bottle of gin she'd found in the pantry. We sat at the kitchen table, exhausted. I scrolled through my eye-screens looking for advice about Dad while Nin played a dumb game on her retinas. "What about Nostalgia?" I asked. "That app came and went in the twenties," Nin said. "Not according to this." I blinked the article to her and she scanned it without stopping her game. "Whoa," she mumbled. "I had no clue old people were using it." She blinked me a hyperlink from the comment section, and...

A new species of Pseudoacanthocephalus (Acanthocephala: Echinorhynchidae) from the guttural toad, Sclerophrys gutturalis (Bufonidae), introduced into Mauritius, with comments on the implications of the introductions of toads and their parasites into the UK.

Pseudoacanthocephalus goodmani n. sp. is described from faecal pellets collected from Sclerophrys gutturalis (Power, 1927), the guttural toad. The species is characterized by a suite of characters, including a proboscis armature of 14-18 longitudinal rows of 4-6 hooks with simple roots, lemnisci longer than the proboscis receptacle, equatorial testes, a cluster of elongated cement glands and eggs without polar prolongations of the middle membrane 72.6-85.8 long. The toad had been accidentally translocated from Mauritius to the UK in a tourist's luggage and survived a washing machine cycle. The guttural toad was introduced into Mauritius from South Africa in 1922 and the cane toad, Rhinella marina (Linneaus, 1758), from South America, between 1936 and 1938. It seems most likely, therefore, that P. goodmani was introduced, with the guttural toad, from South Africa. The cane toad is host to the similar species, Pseudoacanthocephalus lutzi, from the Americas, but P. lutzi has not been recorded from places where the cane toad has been introduced elsewhere. Clearly, the guttural toad is a hardy and adaptable species, although it seems unlikely that it could become established in Northern Europe. Nevertheless, any accidental translocation of hosts poses the potential risk of introducing unwanted pathogens into the environment and should be guarded against.

Determination of the Optimal Parameters of the Metal Can Washing Machine

This article reflects the results of experimental studies on determining the can surface cleaning quality. Two-stage washing of can surfaces was performed based on the results of the factor-at-a-time experiments. It furnished a number of dependences of cleaning quality on the detergent concentration at different washing solution temperatures, as well as on the washing solution temperature at various solution concentrations at fixed washing machine drive wheel rotation frequency. Based on the findings of the studies carried out, it was proved that the cleaning quality indicators increase sharply when the washing solution concentration ranges between 1 and 3 g/L. The optimum temperature providing high-quality cleaning of the can surface as per the standard ranges between 65 and 85°C, and the optimal rotation frequency of the washing machine drive wheel is 20-35 min-1.

An Iterative, Self-Assessing Entity Resolution System: First Steps toward a Data Washing Machine

Data curation is the process of acquiring multiple sources of data, assessing and improving data quality, standardizing, and integrating the data into a usable information product, and eventually disposing of the data. The research describes the building of a proof-of-concept for an unsupervised data curation process addressing a basic form of data cleansing in the form of identifying redundant records through entity resolution and spelling corrections. The novelty of the approach is to use ER as the first step using an unsupervised blocking and stop word scheme based on token frequency. A scoring matrix is used for linking unstandardized references, and an unsupervised process for evaluating linking results based on cluster entropy. The ER process is iterative, and in each iteration, the match threshold is increased. The prototype was tested on 18 fully-annotated test samples of primarily synthetic person data varied in two different ways, good data quality versus poor data quality, and a single record layout versus two different record layouts. In samples with good data quality and using both single and mixed layouts, the final clusters had an average F-measure of 0.91, precision of 0.96, and recall of 0.87 outcomes comparable to results from a supervised ER process. In samples with poor data quality whether mixed or single layout, the average F-measure was 0.78, precision 0.74, and recall 0.83 showing that data quality assessment and improvement is still a critical component of successful data curation. The results demonstrate the feasibility of building an unsupervised ER engine to support data integration for good quality references while avoiding the time and effort to standardize reference sources to a common layout, design, and test matching rules, design blocking keys, or test blocking alignment. Also, the paper proposes how unsupervised data quality improvement processes could also be incorporated into the design allowing the model to address an even broader range of data curation applications.
