Wireless sensor networks (WSN) have become an integral part of our daily lives due to their small size, smart technology, lower cost, and wireless communication capabilities. In this paper, we propose a new WSN topology based on a hierarchical routing protocol. Additionally, we propose an enhancement to the DV-hop algorithm. Our proposed topology differs from existing approaches, and our enhanced algorithm improves upon the original DV-hop algorithm. The performance evaluations are globally satisfactory.

Abstract The traditional machine translation algorithm faces low efficiency and low accuracy due to complex grammar and multiple rules of English noun phrases. A kind of noun phrase identification method based on a rough set was proposed to improve the accuracy of English noun phrases.

The traditional machine translation algorithm faces low efficiency and low accuracy due to complex grammar and multiple rules of English noun phrases. A kind of noun phrase identification method based on a rough set was proposed to improve the accuracy of English noun phrases. The rough set method regarded the identification of English noun phrases as a decision problem. We used rough set theory to reduce features, optimize rules for English noun phrases, and finally identify them. Then, a simulation experiment was carried out on an English noun phrase sample on the Wall Street Journal (WSJ) using rough set theory. The stimulation demonstrated that the accuracy of the noun phrase improved by the rough set was higher than another translation method; therefore, it is an effective machine identification method for English noun phrases, providing a basis for practical design.

Abstract Information Systems and Technologies (IST) in healthcare have evolved gradually, and theories about adopting and maturing information systems and technologies are sufficiently established in organisational management literature. In this paper, we approach the evolution of IST in healthcare, introducing the concepts associated with maturity models, addressing the generic maturity model for IST management, and explicitly presenting the main maturity models... Information Systems and Technologies (IST) in healthcare have evolved gradually, and theories about adopting and maturing information systems and technologies are sufficiently established in organisational management literature. In this paper, we approach the evolution of IST in healthcare, introducing the concepts associated with maturity models, addressing the generic maturity model for IST management, and explicitly presenting the main maturity models focusing on the management of IST in healthcare. Relatively to the last ones, we conclude that there is still a way to go in having widespread and detailed maturity models available. Read More Read Less
