Persistent localization and life-long mapping in changing environments using the Frequency Map Enhancement

Abstract: We present a lifelong mapping and localisation system for long-term autonomous operation of mobile robots in changing environments. The core of the system is a spatio-temporal occupancy grid that explicitly represents the persistence and periodicity of the individual cells and can predict the probability of their occupancy in the future. During navigation, our robot builds temporally local maps and integrates then into the global spatio-temporal grid. Through re-observation of the same locations, the spatio-temporal grid learns the long-term environment dynamics and gains the ability to predict the future environment states. This predictive ability allows to generate time-specific 2d maps used by the robot's localisation and planning modules. By analysing data from a long-term deployment of the robot in a human-populated environment, we show that the proposed representation improves localisation accuracy and the efficiency of path planning. We also show how to integrate the method into the ROS navigation stack for use by other roboticists.

Connecting entrepreneurial and action learning in student-initiated new business ventures: the case of SPEED

Abstract: The Student Placements for Entrepreneurs in Education (SPEED) project ran in 12 higher education institutes in the UK between 2006 and 2008, providing an innovative, action learning-based route that enabled students to start new business ventures as self-started work experience, and has influenced successor programmes. The paper addresses three questions: (1) What is known about action learning and entrepreneurial learning in relation to new venture creation? (2) What can the case of SPEED add to our understanding of the conceptual and practical connections between entrepreneurial learning and action learning? (3) What can be achieved through universities working collaboratively to make a significant and coordinated impact on graduate entrepreneurship by using action learning as a mediating means? It connects action learning with theories of new venture creation and entrepreneurial learning, with reference to relevant literature showing increasing evidence of innovative practices of action learning within...
