Genetic Algorithm based Application Research in Computer Network Security Evaluation

Network security is a complex systematic job. Current safety methods available are having some shortcomings like feasibility , man made interference, smaller application scope and so on. The imitation results shows that using the established evaluation model for network security assessment is simple, also eliminate the interference of human factors and can quickly find the correct results of the assessment. This article provides new ideas and methods to work for a wide-ranging evaluation of computer network security condition, specially with a certain reference value to predict and control of network security issues in the futur

Enhancing Auction Systems with Blockchain Technology

This research paper examines the use of blockchain technology in auction systems. Traditional auction systems face issues related to trust, transparency, and security. Blockchain offers a decentralized and immutable solution that can enhance the efficiency, security, and transparency of auctions. The paper provides an overview of blockchain technology and identifies the challenges in traditional auctions that blockchain can address. It explores existing blockchain-based auction systems and evaluates their effectiveness in mitigating issues such as bid manipulation and fraud. The impact of blockchain on auction participants is also discussed, including benefits like increased trust and reduced transaction costs, as well as challenges related to adoption and scalability. The paper considers both theoretical and practical aspects, analyzing case studies and implementation challenges. It concludes by summarizing the key findings and suggesting future research directions to advance the application of blockchain in auction systems. The auction contract allows users to place bids and determine the highest bidder within a specified time period. The contract also provides functionality for canceling the auction and finalizing it by transferring the funds to the appropriate recipients

A Systematic and Comparative Analysis of Semantic Search Algorithms

Users often struggle to discover the information they need online because of the massive volume of data that is readily available as well as being generated every day in the today’s digital age. Traditional keyword-based search engines may not be able to handle complex queries, which could result in irrelevant or insufficient search results. This issue can be solved by semantic search, which utilises machine learning and natural language processing to interpret the meaning and context of a user's query. In this paper we focus on analyzing the BM-25 algorithm, Mean of Word Vectors approach, Universal Sentence Encoder model, and Sentence-BERT model on the CISI Dataset for Semantic Search Task. The results indicate that, the Finetuned SBERT model performs the best

Sewing Needle Migrating from Esophagus into Prevertebral Space: A Challenging Case

Oesophageal foreign body presents as a medical emergency and requires immediate evaluation and treatment. We are reporting a rare case of sewing needle in esophagus migrating into the prevertebral space at thoracic inlet level. A 13-year-old mentally retarded female child was brought in emergency at midnight with complaint of accidental ingestion of sewing needle with the thread. Patient was posted for rigid esophagoscopy under general anaesthesia, no needle could be visualised and only thread of the sewing needle was removed. So patient was taken up for neck exploration along with gastroenterologists. Further careful dissection confirmed the needle in the pre vertebral space, which was removed successfully with artery forceps. Patient was given IV antibiotics for 10 days. Patient had an uneventful recovery and was discharged after 10 days. Pointed metallic slender foreign bodies can perforate and migrate very fast in the neck or chest and can lead to morbidity and mortality. Multidisciplinary approach offers a great advantage in surgical planning and proper patient management

Broken Metallic Tracheostomy Tube Migrating into the Tracheobronchial Tree

Foreign body aspiration can be a life-threatening emergency. Broken tracheostomy tube in tracheobronchial tree is one of the rarest types of foreign body reported. Here we report two cases of fracture of metallic tracheostomy tube, leading to foreign body in tracheobronchial tree. A 14-year-old girl presented to our Emergency Department with history of respiratory distress and violent bouts of cough since 2 days. Chest X-ray showed that the broken part of the tube was lodged in the right main bronchus. The presence of Parkinson’s disease in the patient and restricted neck flexion offered a challenge both for the anaesthetist and the surgeon. We were successful in removing the broken tube in 13 small pieces. Check bronchoscopy was clear and the procedure went uneventful. We would like to conclude that broken tracheostomy tube presenting as foreign body bronchus is infrequent but it is a preventable complication of tarcheostomy. The patient must be kept on regular follow up to check for signs of wear and tear. Timely and periodic replacement of tracehostomy tube should also be done, otherwise such life-saving surgery can become lifethreatening
