Application of optimization algorithm for virtual reference tag assisted localization and tracking of RFID

SummaryIn an indoor setting, the radio frequency communication is utilized to locate and track mobile objects utilizing Radio Frequency Identification (RFID) technology. Measurements from the Received Signal Strength Indicator (RSSI) are typically the foundation of the localization technique. In an RFID‐based interior setting, lowering tracking mistakes and increasing the precision of tracking remain difficult tasks. In order to address these issues, we developed the VIRALTRACK (Virtual Reference Tag Localization and Tracking) framework that consists of four procedures: deep reinforced learning‐based tracking, quantum‐based localization, optimization‐based virtual reference tag allocation, and signal enhancement. In order to increase the signal's effectiveness, we initially suggested using the Extended Gradient Filter (EGF) technique to eliminate RSSI oscillations. In the second step, we suggested using the Emperor Penguin Colony (EPC) optimization technique to allocate the virtual reference tag while taking the number of tags, SNR, and temperature and humidity of the surroundings into account. In the third phase, we use a quantum neural network (QNN) for localization in order to estimate the position of the moving target. We introduced the SignRank approach to select the best virtual reference tag for localization, which lowers tracking mistakes. In conclusion, we presented the Twin Delayed Deep Deterministic Policy Gradient (TD3) method that boosts the tracking precision by tracking the moving target tag efficiently and taking into account stage, the orientation, distance, and valuable coordinates. The NS3.26 network simulator is used to run the simulation, and tracking precision, tracking error, and accumulated probabilities are used to assess effectiveness.

The Startup Analysis Canvas: Smartfill RFID System

Abstract: In today's fast-paced world, convenience and efficiency are paramount, extending to mundane tasks like refueling vehicles. Traditional gas station payment methods involvingcash or credit cards can be cumbersome and time-consuming. Radio Frequency Identification (RFID) technology offers a promising solution to expedite gas station transactions, enhancing the customer experience. An RFID-based payment system leveragestags affixed to vehicles or issued as cards. Upon pulling up to an RFID-enabled pump, the reader automatically identifies the customer's vehicle or card, retrieving linked account information. The customer simply authorizes fueling, and the designated amount is seamlessly deducted from their account. This eliminates the need to exit the vehicle, searchfor wallets or cards, and swipe or insert them at the pump, significantly reducing transaction times. The benefits of an RFID-based payment system are manifold. First and foremost, it offers unparalleled convenience. Customers can streamline the fueling process without fumbling for cards or cash, leading to a more pleasant and time-efficient experience.Furthermore, RFID technology translates to shorter queues and improved customersatisfaction at gas stations. Reduced transaction times at pumps lead to faster throughput,benefiting both customers and gas station operators. Security is another significant advantage of RFID-based payments. Unlike traditional methods susceptible to fraud, RFID tags are tamper-proof and difficult to replicate. This significantly reduces the risk of unauthorized transactions and fraudulent activity, enhancing financial security for both customers and gas station businesses. Additionally, RFID technology offers potential for integration with loyalty programs. The system can be designed to automatically identify customers and credit their accounts with loyalty points based on their purchases. This fosters customer engagement and incentivizes repeat business, creating a win-win situation for both gas stations and their patrons. While RFID-based payment systems hold immense promise, there are challenges to consider. Implementation costs associated with equipping gas stations with RFID readers and potentially issuing tags to customers need to be carefully evaluated. Additionally, customer adoption is a crucial factor.Encouraging widespread acceptance of this new technology may require educational campaigns to highlight the benefits and dispel any misconceptions

Experimental Ecotoxicology Procedures Interfere with Honey Bee Life History.

Apis mellifera was used as a model species for ecotoxicological testing. In the present study, we tested the effects of acetone (0.1% in feed), a solvent commonly used to dissolve pesticides, on bees exposed at different developmental stages (larval and/or adult). Moreover, we explored the potential effect of in vitro larval rearing, a commonly used technique for accurately monitoring worker exposure at the larval stage, by combining acetone exposure and treatment conditions (in vitro larval rearing vs. in vivo larval rearing). We then analyzed the life-history traits of the experimental bees using radio frequency identification technology over three sessions (May, June, and August) to assess the potential seasonal dependence of the solvent effects. Our results highlight the substantial influence of in vitro larval rearing on the life cycle of bees, with a 47.7% decrease in life span, a decrease of 0.9 days in the age at first exit, an increase of 57.3% in the loss rate at first exit, and a decrease of 40.6% in foraging tenure. We did not observe any effect of exposure to acetone at the larval stage on the capacities of bees reared in vitro. Conversely, acetone exposure at the adult stage reduced the bee life span by 21.8% to 60%, decreased the age at first exit by 1.12 to 4.34 days, and reduced the foraging tenure by 30% to 37.7%. Interestingly, we found a significant effect of season on acetone exposure, suggesting that interference with the life-history traits of honey bees is dependent on season. These findings suggest improved integration of long-term monitoring for assessing sublethal responses in bees following exposure to chemicals during both the larval and adult stages.

Pebble tracing experiment at the Promenade des Anglais (Nice, France): A contribution towards beach management efforts

In this paper, the results of a short-term tracing experiment carried out at a beach compartment along the Bay of Nice (southern France) are presented. Nice urban beach is characterized by persistent offshore sediment loss issues that force the local administration to operate frequent artificial replenishments to maintain the current configuration, which also protects the well-renown Promenade des Anglais from high-energy events. As beach refills are quite expensive, the aim of the paper is to provide novel insights about the transport processes of pebble-sized tracers, which might support the Municipality to better adjust future interventions. Pebbles were tracked by means of the Radio Frequency Identification technology, largely used in such settings because of its reliability and efficiency. In addition, the morphology of the beach was monitored during the three-days-long experiment by airborne and ground topographic surveys, as well as the shape and the size of the tracers. Finally, a wave model was produced to simulate wave propagation in the nearshore, which validates the observed transport patterns. The results documented a low recovery rate (56%) 4 h after tracer injection, which is uncharacteristic considering that it jumped to 91% after the second survey, 24 h after the injection. At the end of the experiment (48 h), the recovery rate sank to 14%. These data were adequate to identify a few trends in pebble transport: tracer recovery rate in the swash zone was very low, while many marked pebbles were found at the step crest. Although this transport pattern may corroborate the offshore movement of the sediments, the topographic surveys revealed the destruction and re-formation of the fair-weather berm overnight, which would imply the presence of a shoreward transport under low energy wave conditions. While size did not single out any tendency, shape did: spheres rolled down the beachface earlier than disks; by contrast, disk-shaped pebbles moved for longer distances than spheres. These findings will be useful for local coastal managers because next beach fills will be planned and optimized based on the observed transport patterns. Though the selection of disk-shaped pebbles implies increasing costs, replenishments would be more efficient and fine-tuned for this sector of coast, which would ultimately save resources reducing negative impacts on the environment along the way. These considerations are valid for the Bay of Nice, but they might be useful wherever coarse-clastic beaches need recurring replenishments.

A decision-making problem for product outsourcing with flexible production under a global supply chain management

Any product outsourcing expands the geological boundaries of production industries under the global supply chain management. The global outsourcing increases concerns for production industries, which is less for domestic supply chain management. Two main strategy makings for product outsourcing under the global supply chain are the proper information about products and services for those products. This study examines a service-driven digital global supply chain management to find intriguing factors for product outsourcing decision-making with international tax, dollar rate, and tariff. The flexible production & the production–transportation lead time of manufacturers and two-stage safety factors of retailers are features of the digital global supply chain. Manufacturers develop a new investment strategy on radio frequency identification technology for product information sharing with retailers. Both manufacturers and retailers pay carbon tax for all products along with transportation for the environmental development. A classical optimization technique finds the global optimum profit of the global supply chain management. Numerical results establish service and safety stock of products as two decision-making factors for digital global supply chain management. The profit is high when retailers are situated in a low-economy country with high service. Retailers in a high-economy country with no service cause a 57.98% loss than the original profit. This phenomenon justifies that local customers can put their trust in buying imported products when they are sure about product-related services. Comparison, discussions, and sensitivity analysis are provided for a detailed result analysis.
