DEEP BAYESIAN ACTIVE LEARNING IN HIGH-RESOLUTION SATELLITE IMAGES FOR CHANGE DETECTION IN URBAN AND SUBURBAN AREAS

In this work the problem of change detection in high-resolution (HR) satellite images is addressed. The active learning (AL) algorithm Bayesian active learning disagreement (BALD) is applied on WorldView images of urban and suburban areas in the island of Crete, Greece. Comparisons with results from random sampling (RS) on AL are carried out. Several cases of selecting different amounts of images in the training set of a convolutional neural network (CNN) are experimented. The results show that the validation accuracy of classification as changed or unchanged of the BALD algorithm is superior to that of the RS algorithm. Indeed, the BALD algorithm achieves zero test error against the test errors 34.6% and 38.5% of the RS algorithm. Actually, as the amount of training images increases, the accuracy also increases. Interesting experiments could be executed in the future utilizing estimators from robust statistics inside the AL acquisition function framework. Up to now in the literature no other work has appeared to present deep AL on WorldView images for change detection.

Effect of Collagen Cross-Link Deficiency on Incorporation of Grafted Bone

Bone matrix collagen, is one of the major contributors to bone quality. No studies have examined how bone quality affects the results of bone transplantation. Collagen cross-links (CCL) are the key factor in collagen properties. The purpose was to investigate the influences of CCL for both grafted bone and recipient site bone on the success of bone augmentation. Four-week-old male Wister rats (n = 54) were divided into control and test groups. Control and test groups equally sub-divided into donors and recipients. An additional six rats were used to characterize bone at day zero. Test groups received 0.2% beta-aminoproperionitrile (BAPN) for 4 weeks as CCL inhibitor. Animals were further divided into donor and recipient groups. The transplanted bone chips integrated with host bone by 25% more in CCL-deficient animals compared to control. However, no difference in cortical thickness among all conditions. CCL-deficient transplanted bone did not show any extra signs of osteocyte apoptosis, while sclerostin expression was comparable to that in control. The host periosteum of CCL-deficient animals showed higher cellular activity, as well as higher bone quantity and osteoclast activity. Collagen cross-links deficiency in host bone might accelerate the incorporation of grafted bone. effect. Incorporation of the bone grafts appears to depend mainly on host condition rather than graft condition.

MORAL EDUCATION IN JAPANESE SCHOOLS A MODEL FOR IMPROVING CHARACTER EDUCATION IN INDONESIA

Moral or character education has been playing an important role in educating children, teenagers, and younger people noble values of Japanese cultures. This research is based on two research questions: how the practice of moral education in Japanese schools is and how the model for improving character education in Indonesian schools is. This is a qualitative field research with phenomenological approach, in which the data were collected in Japanese schools by using observation, indepth interview, and documentary. The data were analysed descriptively and continuously. The Japanese government gave one hour lesson for moral education in a week. With the moral education, Japanese younger generation is expected to be able to adapt to the social environment and have the ability to think, to make effective decisions and to act independently. In addition, they are also expected to have ability to identify issues they face, and be able to interact with others in international relations and play an important role in international world as well. Japanese moral education has been using the interactive and communicative approach, promoting moral discovery by learners themselves, avoiding the application of indoctrination approach, and no test or final exam, for every course of study in moral education (zero test). In addition the most important thing is that moral education in Japan applied an integrated and connected approach among three centers of education: school, family, and community. All of three educational environments have very important role as laboratory of moral or character education.

Taming the wild ant-lion; a counterexample to a conjecture of Böhm

In Barendregt (1984), Corrado Böhm conjectured that every adequate (Barendregt 1984, 6.4.2 (ii)) numeral system of normal combinators has normal successor, predecessor and zero test. In this note, we give a counterexample to this conjecture. Our example is shown to have no normal zero test. Böhm has informed us that Intrigila (1994) has given an example with no normal successor. Our strategy, in terms of the ant-lion paradigm, is to pry open the trap so wide that it enters its active state before its jaws are shut.
