School of Engineering and Science Dissertation for a Ph.D. in Computer Science Improving Point Cloud Quality for Mobile Laser Scanning Jan Elseberg November 2013 Supervisor: Prof. Dr. Andreas Nüchter Second Reviewer: Prof. Dr. Andreas Birk Third Reviewer: Prof. Dr. Joachim Hertzberg Fourth Reviewer: Prof. Dr. Rolf Lakämper Date of Defense: 13th of September 2013 Abstract This thesis deals with mobile laser scanning and the complex challenges that it poses to data processing, calibration and registration. New approaches to storing, searching and displaying point cloud data as well as algorithms for calibrating mobile laser scanners and registering laser scans are presented and discussed. Novel methods are tested on state of the art mobile laser scanning systems and are examined in detail. Irma3D, an autonomous mobile laser scanning platform has been developed for the purpose of experimentation. This work is the result of several years of research in robotics and laser scanning. It is the accumulation of many journal articles and conference papers that have been reviewed by peers in the field of computer science, robotics, artificial intelligence and surveying. Danksagung The work that goes into finishing a work like this is long and arduous, yet it can at times be pleasing, exciting and even fun. I would like to thank my advisor Prof. Dr. Andreas Nüchter for providing such joy during my experiences as a Ph.D. student. His infectious eagerness for the subject and his ability to teach are without equal. Prof. Dr. Joachim Hertzberg deserves many thanks for introducing me to robotics and for being such an insightful teacher of interesting subjects. -

Hadley's Octant (A. D. 1731)
HADLEY’S OCTANT (A. D. 1731). On the occasion of the second centenary of the invention of reflecting instruments and in accordance with the usual custom of reproducing in the Hydrographic Review documents of particular interest connected with the history of nautical and hydrographic science, the communication made by John Hadley to the Royal Society of London on 13th May, 1731, is repro duced hereafter in facsimile. This communication was published in N° 420 of the Philosophical Transactions. It appears that the oldest document in which allusion is made to the principle of reflection by plane mirrors, as applied to the measurement of angles, is the History of the Royal Society of London by B ir c h . In this book, under the date of 22nd August, 1666, it is stated “ Mr. H o o k mentionned a new astronomical instrument for making observations of distances by reflection”. In another place it may be read that on the 29th August of the same year, H o o k spoke of this instrument again, it being then under construction, to the members of the Society. They invited him to submit it as soon as possible and this was done on 12th September of that year. The instrument submitted by H o o k differed in important details from the modern sextant; it was provided with but one mirror and thus was a single reflecting instrument. This was the fundamental defect which made it impos sible for H o o k ’s invention to be a success. However, the idea of using reflection from a plane mirror for the measu rement of angles was not forgotten and, in spite of H o o k ’s want of success the principle was taken up by others who sought to correct the disadvantages of the instrument as first invented. -

Lunar Distances Final
A (NOT SO) BRIEF HISTORY OF LUNAR DISTANCES: LUNAR LONGITUDE DETERMINATION AT SEA BEFORE THE CHRONOMETER Richard de Grijs Department of Physics and Astronomy, Macquarie University, Balaclava Road, Sydney, NSW 2109, Australia Email: [email protected] Abstract: Longitude determination at sea gained increasing commercial importance in the late Middle Ages, spawned by a commensurate increase in long-distance merchant shipping activity. Prior to the successful development of an accurate marine timepiece in the late-eighteenth century, marine navigators relied predominantly on the Moon for their time and longitude determinations. Lunar eclipses had been used for relative position determinations since Antiquity, but their rare occurrences precludes their routine use as reliable way markers. Measuring lunar distances, using the projected positions on the sky of the Moon and bright reference objects—the Sun or one or more bright stars—became the method of choice. It gained in profile and importance through the British Board of Longitude’s endorsement in 1765 of the establishment of a Nautical Almanac. Numerous ‘projectors’ jumped onto the bandwagon, leading to a proliferation of lunar ephemeris tables. Chronometers became both more affordable and more commonplace by the mid-nineteenth century, signaling the beginning of the end for the lunar distance method as a means to determine one’s longitude at sea. Keywords: lunar eclipses, lunar distance method, longitude determination, almanacs, ephemeris tables 1 THE MOON AS A RELIABLE GUIDE FOR NAVIGATION As European nations increasingly ventured beyond their home waters from the late Middle Ages onwards, developing the means to determine one’s position at sea, out of view of familiar shorelines, became an increasingly pressing problem. -
Security Council
10/28/13 Security Council Advocates Greater Ties with Organization of Islamic Cooperation to Resolve Conflict in Middle East, Other Strife-Torn Regions 28 October 2013 Security Council SC/11161 Department of Public Information • News and Media Division • New York Security Council 7050th Meeting (AM) SECURITY COUNCIL ADVOCATES GREATER TIES WITH ORGANIZATION OF ISLAMIC COOPERATION TO RESOLVE CONFLICT IN MIDDLE EAST, OTHER STRIFE-TORN REGIONS The Security Council today recognized the importance of strengthened cooperation with the Organization of Islamic Cooperation (OIC), acknowledging the United Nations’ continued dialogue with the 57-member body in the areas of peacemaking, preventive diplomacy, peacekeeping and peacebuilding. In a presidential statement adopted by consensus, the Council commended OIC States for their ongoing contribution of troops to United Nations peacekeeping operations. It noted that the United Nations and OIC shared common objectives in promoting resolution of the Israeli-Palestinian conflict, and a political solution to the Syrian conflict, in line with the 30 June 2012 Geneva Communiqué, as well as in fostering solutions to other conflicts. Noting the commitment of the United Nations and OIC to foster a global dialogue on tolerance and peace, the Council called for enhanced cooperation towards a better understanding across countries, cultures and civilizations. It also asked the Secretary-General to include in his next biannual report recommendations on ways to enhance such cooperation. In opening remarks, United Nations Secretary-General Ban Ki-moon touched on various issues where the United Nations’ work with OIC continued to be critical. In Syria, the organizations cooperated on humanitarian and political issues amid heightened tensions between Sunni and Shia communities. -
1 Statement of the Secretary General of the OIC Professor Ekmeleddin
PC.DEL/345/10 6 May 2010 Statement of the ENGLISH only Secretary General of the OIC Professor Ekmeleddin Ihsanoglu to the Permanent Council of the OSCE 6 May 2010 Mr. Chairman, Mr. Secretary General, Excellencies, Distinguished Representatives, Allow me at the outset to express my appreciation to you, Mr. Chairman, for the opportunity to address the Permanent Council of the OSCE. I fondly recall my interaction with the Permanent Council in November 2005, soon after my election as the Secretary General of the Organization of the Islamic Conference. I believe that occasion had marked the beginning of a mutually beneficial relationship between our two organizations that has grown steadily over the past five years. Today is another welcome occasion to share with you my viewpoints on issues of mutual concern from the perspective of the Organization of the Islamic Conference, OIC in short. The goals and objectives of the OIC are not much different from those of the OSCE, as both our organizations are devoted to the cause of international peace and security. The scope of cooperation between the OIC and the OSCE is, therefore, immense and we need to take full advantage of the opportunity by giving further impetus to our existing cooperation through increased interaction and consultations. I would like to avail this opportunity to pay a special tribute to the Kazakh Chairmanship of the OSCE in successfully fulfilling its heavy but pleasant responsibility. What is of particular significance is that Kazakhstan’s Chairmanship of the OSCE will be a run up to the Chair of the OIC in 2011. -
A Survey for Low-Mass Stellar and Substellar Members of the Hyades Open Cluster
Astronomy & Astrophysics manuscript no. aa30134-16˙12Jan2018 © ESO 2018 January 16, 2018 A survey for low-mass stellar and substellar members of the Hyades open cluster. Stanislav Melnikov1;2 and Jochen Eislo¨ffel1 1 Thuringer¨ Landessternwarte Tautenburg, Sternwarte 5, 07778 Tautenburg, Germany 2 Ulugh Beg Astronomical Institute, Astronomical str. 33, 700052 Tashkent, Uzbekistan Received / Accepted ABSTRACT Context. Unlike young open clusters (with ages < 250 Myr), the Hyades cluster (age ∼ 600 Myr) has a clear deficit of very low-mass stars (VLM) and brown dwarfs (BD). Since this open cluster has a low stellar density and covers several tens of square degrees on the sky, extended surveys are required to improve the statistics of the VLM/BD objects in the cluster. Aims. We search for new VLM stars and BD candidates in the Hyades cluster to improve the present-day cluster mass function down to substellar masses. Methods. An imaging survey of the Hyades with a completeness limit of 21m: 5 in the R band and 20m: 5 in the I band was carried out with the 2k × 2k CCD Schmidt camera at the 2m Alfred Jensch Telescope in Tautenburg. We performed a photometric selection of the cluster member candidates by combining results of our survey with 2MASS JHKs photometry. Results. We present a photometric and proper motion survey covering 23.4 deg2 in the Hyades cluster core region. Using optical/IR colour-magnitude diagrams, we identify 66 photometric cluster member candidates in the magnitude range 14m: 7 < I < 20m: 5. The proper motion measurements are based on several all-sky surveys with an epoch difference of 60-70 years for the bright objects. -

Atlas-Country-Case-Malaysia.Pdf
Malaysia has long had the target of becoming a knowledge-based Malaysia economy by 2020. Creating a vibrant environment for science and innovation is seen as the best way for the country to escape the middle- income trap. The last few decades have seen record levels of investment in education and research. Shining new labs and special zones for technology and entrepreneurship reflect the government’s ambitions, yet challenges such as a shortage of talent and bloated bureaucracy seem to hinder progress. Looking across all the different elements within Malaysia’s science and innovation system, is the current blend of initiatives and strategies the right model for a more innovative Malaysia? This report provides a comprehensive snapshot of the key aspects of Malaysia’s science and innovation system, looking at the recent history and future prospects. It suggests how Malaysia might overcome some barriers to innovation, from consolidating and streamlining existing government policies to becoming a leader amongst other bio-diverse countries. Whilst often overshadowed by other rising Asian powers, this study argues that the international research community would be well advised to look to Malaysia for future collaborations. Malaysia is the first country study to be released as part of the Atlas of Islamic- World Science and Innovation. Bringing together partners from across the Islamic world, Europe and North America, the Atlas project is exploring the changing landscape of science and innovation across a diverse selection of countries with large Muslim populations. Further details of the project are provided within.
