A review of travel time estimation and forecasting for advanced traveler information systems

Providing on line travel time information to commuters has become an important issue for Advanced Traveler Information Systems and Route Guidance Systems in the past years, due to the increasing traffic volume and congestion in the road networks. Travel time is one of the most useful traffic variables because it is more intuitive than other traffic variables such as flow, occupancy or density, and is useful for travelers in decision making. The aim of this paper is to present a global view of the literature on the modeling of travel time, introducing crucial concepts and giving a thorough classification of the existing tech- niques. Most of the attention will focus on travel time estimation and travel time prediction, which are generally not presented together. The main goals of these models, the study areas and methodologies used to carry out these tasks will be further explored and categorized.

Emerging Practice in a Digital Age: A guide to technology-enhanced institutional innovation

Since the launch of the JISC guide Innovative Practice with e-Learning (JISC, 2005), so much has changed. At that time, early adopters were exploring the potential of mobile and wireless learning. Since then, the increased availability of public and institutional wireless networks, the emergence of new and more powerful technologies and an increase in personal ownership of these technologies are changing the way we connect, communicate and collaborate. Emerging Practice in a Digital Age, one of a series of Effective Practice guides, draws on recent JISC reports and case studies and looks at how colleges and universities are continuing to embrace innovation and respond to changes in economic, social and technological circumstances in a fastchanging world.

Learning in a Digital Age: Extending higher education opportunities for lifelong learning

Learning in a Digital Age is one in a series of Effective Practice guides. It demonstrates, through a range of case studies, how institutions are using technology to attract and retain diverse groups of learners, offer professional development opportunities for their staff, and enhance engagement and collaboration with employers and other organisations with a stake in effective lifelong learning.

Effective Assessment in a Digital Age

What contribution can technology make to ensuring that assessment and feedback processes are agile, streamlined and capable of promoting high-quality learning? Effective Assessment in a Digital Age, one in a series of Effective Practice guides, draws on recent JISC reports and case studies depicting different contexts and modes of learning to explore the relationship between technology enabled assessment and feedback practices and meaningful, well-supported learning experiences.

Effective Practice in a Digital Age

Effective Practice in a Digital Age is designed for those in further and higher education who aim to enhance the student learning experience through apt and imaginative uses of technology. A visually rich publication, Effective Practice in a Digital Age outlines key aspects of designing learning in a technology-rich context and is structured to address the needs of experienced practitioners as well as those new to technology-based learning and teaching – the ten newly researched case studies offer a choice of pathways reflecting the diversity of approaches taken by practitioners in current UK practice.

Size and year class composition of catch, age and growth of yellowfin tuna in the Eastern Tropical Pacific Ocean for the years 1954-1958

ENGLISH: Data on the size composition of catch for the years 1954-1958 have been studied to determine year class composition, age and growth of yellowfin tuna in the Eastern Tropical Pacific Ocean. Direct age determination of tropical tunas has not yet proven reliable; however, this analysis has shown that the length-frequency distributions themselves are adequate to determine year class structure and growth rates. Absolute age has been estimated by comparing the average time of spawning with the time at which age groups initially appear in the catch. SPANISH: Los datos sobre la composición del tamaño de la pesca durante los años 1954-1958 han sido estudiados con el objeto de determinar la composición de las clases anuales, la edad y el crecimiento del atún aleta amarilla en el Océano Pacífico Oriental Tropical. Las determinaciones directas de la edad de los atunes tropicales no han probado todavía ser de confianza; sin embargo, este análisis ha demostrado que las distribuciones de la frecuencia de las longitudes son adecuadas para determinar la estructura de las clases anuales y de las tasas de crecimiento. La edad absoluta ha sido estimada mediante la comparación de la época promedio de desove con la epoca en que los grupos de edades comienzan a aparecer en la pesca.

A method for age determination of dolphins.

The use of growth layers in teeth as an indicator of age in odnotocetes and pinnipeds was suggested by Laws (1954) and since then the method has been used extensively in both marine and non-marine mammals. Dentinal growth layers are groups (growth layer groups) of repetitive alternating bands which in cross-section are similar to growth rings in trees. The most commonly used methods for counting growth layer groups (GLGs) are by undecalcified longitudinal thin sections (150 um) or decalcified and stained thin sections (10-30 um). In longitudinal sections viewed with light microscopy, GLGs appear as opaque and translucent cones nestled one inside another, with the oldest dentine Iying adjacent to the enamel, and the newest layer borderinq the pulp cavity.
