Enabling Real-Time Remote Monitoring of Ships by Lossless Protocol Transformations

This paper uses data processing techniques to reduce the required transmission bandwidth in ship-to-shore communications. The proposed framework (ONline Efficient Sources Transmission Optimizer -) leverages state-of-the-art technologies and novel algorithms to automatically optimize transmissions under structural (e.g., available bandwidth, fixed packet overhead) and user-defined (e.g., maximum latency) constraints. In addition, authenticates and encrypts the communication between the ship and the shore via mainstream free and open-source software components. Initially, we present the abstract mathematical formulation of the problem, with its assumptions, goal function, constraints, and significant quantities. Then, we introduce the architecture of a system capable of continuously estimating the compressibility, processing and transmission time of streaming data. Such estimations allow to calculate and apply optimal parameters for achieving the best compression ratio. Lastly, using a prototypical implementation, we evaluate the system performance with a Class B ship simulator on two realistic use cases. Our experiments show an excellent compression ratio with maritime protocols (more than 40:1) and a limited latency impact, demonstrating the approach's viability

Vegetarian epidemiology: Review and discussion of findings from geographically diverse cohorts

Epidemiologic cohort studies enrolling a large percentage of vegetarians have been highly informative regarding the nutritional adequacy and possible health effects of vegetarian diets. The 2 largest such cohorts are the European Prospective Investigation into Cancer and Nutrition–Oxford (EPIC-Oxford) and the Adventist Health Study–2 (AHS-2). These cohorts are described and their findings discussed, including a discussion of where findings appear to diverge. Although such studies from North America and the United Kingdom have been important, the large majority of the world's vegetarians live in other regions, particularly in Asia. Findings from recent cohort studies of vegetarians in East and South Asia are reviewed, particularly the Tzu Chi Health Study and Indian Migration Study. Important considerations for the study of the health of vegetarians in Asia are discussed. Vegetarian diets vary substantially, as may associated health outcomes. Cohort studies remain an important tool to better characterize the health of vegetarian populations around the globe

The road to Ithaca: a mentee’s and mentor’s journey

In this article a teacher/researcher and an academic mentor explore the potency, possibilities and tensions of the mentoring relationship from personal perspectives. The concept of mentoring as described in this article uses the model of mentor/mentee relationship as portrayed in Homer's epic narrative the Odyssey. In the examination of the experience of the mentoring process, as it was interpreted and implemented by Genie Gabel-Dunk and Anna Craft, significant elements emerge as tools for professional development: Being a Teacher to a Teacher; Being a Role Model; Being a Counsellor; Being a Facilitator; Being a Supportive Protector; and Being a Guide. The concept of mentorship is critical to quality education in that it fosters the creativity, professional development and growth of individuals and is a facilitator in the passing on of skills and professional standards. The authors believe that if as educators we value individuality, then we must work diligently to preserve the concept and practice of mentorship within the current context of the economic rationalisation of teaching resources
