Journal Vol – 19 No -1, January 2024 Journal > Journal > Journal Vol – 19 No -1, January 2024 RELIABILITY OPTIMIZATION OF A DEGRADED SYSTEM UNDER PREVENTIVE MAINTENANCE USING GENETIC ALGORITHM Authors: Shakuntla Singla, Diksha Mangla, Poonam Panwar, S Z Taj DOI NO: https://doi.org/10.26782/jmcms.2024.01.00001 admin January 20, 2024 Abstract: The reliability parameters of a Mathematical model are analyzed for a system with three identical units and a standby. In this study, the primary unit is considered more important due to its high cost and working in two types of degraded conditions before a complete malfunction. Under the concept of preventive maintenance, the states of deterioration are reversed. The working of the system under two different efficiencies is discussed. The reliability of the Mathematical model, depending on the availability and working time, has been optimized using the Mathematical tool “Genetic Algorithm”. The optimum values of all parameters based on the exponential distribution are considered to optimize the reliability, and thus provide maximum benefits to the industry. Sensitivity analysis of the availability and the working time is carried out to understand the effects of changing parameters. Graphical and tabular analyses are presented to discuss the results and to draw conclusions about the system’s behavior.

connected material or device. After detailed investigation, Dr Zhang decided to use calcium as the main cation in the droplet power source. “We are using calcium to create the energy gradient due to its high output performance,” he says. The battery is versatile however, so it’s not limited to a single type of salt. “We can use either organic or inorganic salts – as long as they are water soluble,” continues Dr Zhang. A lot of attention in the project has been focused on maximising the output of the power source, by modifying the concentration gradient to achieve an optimal outcome. There is a trade-off here between the salt gradient and internal resistance. “If we increase the difference between the high-salt concentration and the low-salt concentration, we will have a higher output. But on the other hand, reducing the low-salt concentration to increase the salt gradient can also increase the internal resistance in the system, which will reduce the overall current,” explains Dr Zhang, who feels that a good balance has been found. Further effort is being devoted to controlling the battery output. “We want to be able to turn on the output when we want to, and we also want these batteries to last for a long time,” adds Professor Bayley. In the study, the device could stably store its energy in the off-state for 36 hours. After being triggered to the on-state, the activated droplet power source produced a current which persisted for 30 to 120 minutes. The maximum output power of a unit made of of 5 50-nanolitre droplets was around 65 nanowatts. At the present stage of development, the soft battery has sufficient output to be used as a power source for synthetic tissues. For example, it can induce the movement of charged molecules within a tissue. Professor Bayley says it also holds wider potential for applications with living tissues. “Indeed, these very tiny, microscale, soft batteries have been used to modulate neuronal activity as demonstrated in a published paper (Ref 1 listed in right column) and correct the rhythm of a mouse heart in unpublished work. The batteries — combined with living cells or with hybrid synthetic/living tissues — might eventually be key components in organ repair,” he notes. The droplet battery can also be adapted for different situations. “The size, shape and output of the droplet battery can be modified according to the needs of individual patients, reflecting the nature of an injury,” explains Dr Linna Zhou, an Investigator in the Department of Medicine at Oxford. Modulating the activity of 3D brain tissues A further application of these droplet power sources is in modulating the activity of 3D constructs comprising human neural cells that mimic aspects of brain activity. Dr Zhang says the power source has been tested in this area. “We have already shown that we can use the droplet power source to modulate neuronal activity, for example by stimulating intracellular calcium waves,” he points out. The next step could be to commercialise this research and refine the ideas further outside an academic environment, while Dr Zhang is also keen to explore the wider possibilities of droplet-based iontronic networks. “Following this work, we have been developing other means to generate power, including lithium-ion batteries and enzymemediated biobatteries, both based on microscale, soft droplets,” he says. In addition to the potential of these droplet networks as energy sources, Dr Zhang envisages the use of hydrogel droplets as a platform for other applications. “We can put not only energy components into these droplets, but also integrate other functional components, such as stimulus-responsive nanoparticles, enabling light and magnetic responsiveness,” he continues. “We aim to develop dropletbased systems with a variety of functions in the future, including logic circuits, sensors, microrobots, and drug delivery pumps. Most importantly, these ion-based systems will be small, soft and biocompatible.” 26 EU Research www.euresearcher.com 27 Reliable sources of power are required for the operation of bio-integrated materials and devices, such as the tissue implants that are under development for the repair of damaged organs. Many of the technologies currently used to power these biomaterials have significant shortcomings, says Dr Yujia Zhang, a post-doctoral researcher in Professor Hagan Bayley’s group at the University of Oxford. “For example, lithium batteries are bulky and the materials used to construct them are not soft,” he explains. As part of his work in the EU-funded SYNTISU project, Dr Zhang is working to develop a new type of power source that overcomes these issues. “We are developing tiny, soft, chains of nanolitre (hundreds of micrometres in diameter) droplets comprising conductive hydrogels,” he says. “For example, our five-droplet system contains charge-selective polymers and salts at different concentrations. This allows the cations and anions – positively-charged and negatively-charged ions – to move through the conductive hydrogel in opposite directions, from the high-salt droplets at the two ends to the low-salt droplet in the middle, generating an ionic current and a power output.” Droplet battery This research builds on earlier work in the Bayley group on the development of synthetic tissues, which require an external input to induce directional ion movements, enabling ionic communication between compartments, like cell-cell communications in natural tissue. In contrast to external light and wired-electrode inputs, the droplet battery provides an internal power source that meets this need for the first time. “These batteries are intended to move ions around; they are iontronic power sources,” notes Professor Bayley. Different approaches can be used to fabricate the battery. “In early work, we manually deposited each droplet to fabricate a single unit of five droplets, but we can also use 3D printing to achieve large-scale fabrication,” outlines Dr Zhang. “For droplet chains containing hundreds of droplets, we use a mould to hold them in position. When a battery is fabricated, the droplets are in a pregel state and are separated by lipid bilayers. The battery is activated by gelation of the droplets and removal of the lipid bilayers to form a continuous hydrogel network.” The ions can then flow through the network, and a variety of salts have been investigated in the project as a means of producing an internal energy gradient. Each salt combination produces a different output voltage, which in turn can be used to produce external ion movement in a Many of the technologies currently used to provide power to bio-integrated devices rely on electronic components and circuits, so are bulky and rigid. We spoke to Professor Hagan Bayley, Dr Yujia Zhang and Dr Linna Zhou about their work in developing a miniaturised soft ionic power source and its wider potential in modulating the activities of cells and tissues.
