As online shopping and stores become more popular, the need for electronic coupons is also growing. An electronic coupon (e-coupon) tools are used for various marketing tasks like boosting sales, promoting brands, etc. But the e-coupon administrations are helpless against the security issues on account of centralization. Safeguarding against issues like coupon manipulation, replication, and unauthorized use are of utmost importance in the context of e-coupons. To address this problem, we suggest using a blockchain or distributed ledger technology to enhance safety of the electronic coupon system. Our approach involves setting up server to support the electronic coupon service and connect with blockchain. Additionally, develop a smart contract within the blockchain framework to ensure the reliability of the electronic coupon data. Testing proposed system on a Ethereum-supported blockchain architecture and found that it offers improved security with only a slight decrease in performance compared to the existing e-coupon service.

The main aim of the article is to present the Bulgarian speech resources in the CHILDES automated computerized language data exchange system. The resources are organized into a corpus labeled Bulgarian LabLing Corpus (https://***/access/Slavic/Bulgarian/LabLing. html). This database is the most recent contribution to the CHILDES Slavic collection, the first version of which was published in 2020. It covers longitudinal data from 5 young children and the picture-based narratives of 121 preschoolers. The focus in the first Bulgarian electronic corpus with children's speech is on the possibilities for the study of child-adult speech interaction, which is extremely important for the adequate modeling of language ontogenesis.

This paper studies a mobile edge computing system where two solar-powered nodes (i.e., a relay and an intelligent reflecting surface (IRS)) assist a user node in task offloading to an access point. To save the long-term energy consumption at the user, a novel protocol is first proposed so that the system can adaptively select the operating modes. Then, based on this protocol, the optimization problem of the system is formulated to minimize the energy consumption of task offloading and computing at the user by optimizing the system operation modes and the resource allocation in each mode, subject to the battery energy states of the IRS and the relay with the energy causality constraints. The problem is solved using the Lyapunov optimization framework and an alternating optimization algorithm. Simulation results show that the proposed system optimization scheme can save 70%-95% of energy consumption as compared to the baseline schemes.
