Design and Implementation of a Remote Care Application Based on Microservice Architecture

Microservice Architecture (MSA) is an architectural style for service-based software systems. MSA puts a strong emphasis on high cohesion and loose coupling of the services that provide systems' functionalities. As a result of this, MSA-based software architectures exhibit increased scalability and extensibility, and facilitate the application of continuous integration techniques. This paper presents a case study of an MSA-based Remote Care Application (RCA) that allows caregivers to remotely access smart home devices. The goal of the RCA is to assist persons being cared in Activities of Daily Living. Employing MSA for the realization of the RCA yielded several lessons learned, e.g., (i) direct transferability of domain models based on Domain-driven Design; (ii) more efficient integration of features; (iii) speedup of feature delivery due to MSA facilitating automated deployment.Comment: 8 pages, 3 figures, 2 table

Behavioral Response Of Reef Fish And Green Sea Turtles To Midfrequency Sonar

There is growing concern over the potential effects of high-intensity sonar on wild fish populations and commercial fisheries. Acoustic telemetry was employed to measure the movements of free-ranging reef fish and sea turtles in Port Canaveral, FL, in response to routine submarine sonar testing. Twenty-five sheepshead (Archosargus probatocephalus), 28 gray snapper (Lutjanus griseus), and 29 green sea turtles (Chelonia mydas) were tagged, with movements monitored for a period of up to 4 months using an array of passive acoustic receivers. Baseline residency was examined for fish and sea turtles before, during, and after the test event. No mortality of tagged fish or sea turtles was evident from the sonar test event. There was a significant increase in the daily residency index for both sheepshead and gray snapper at the testing wharf subsequent to the event. No broad-scale movement from the study site was observed during or immediately after the test
