Vision-based simultaneous localization and mapping (vSLAM) is a well-established problem in mobile robotics and monocular vSLAM is one of the most challenging variations of that problem nowadays. In this work we study one of the core post-processing optimization mechanisms in vSLAM, e.g. loop-closure detection. We analyze the existing methods and propose original algorithm for loop-closure dete...

This paper expounds a Chinese word segmentation system built for the Fourth SIGHAN Bakeoff. The system participates in six tracks, namely the CityU Closed, CKIP Closed, CTB Closed, CTB Open, SXU Closed and SXU Open tracks. The model of Conditional Random Field is used as a basic approach in the system, with attention focused on the construction of feature templates and Chinese character categor...

This document describes the properties and use of a revised Microsoft Word template (.dot) for writing Internet Drafts and RFCs. It replaces the initial template described in RFC 3285 to more fully support Word's outline modes and to be easier to use. This template can be direct-printed and direct-viewed, where either is line-for-line identical with RFC Editor-compliant ASCII output. This versi...

The importance of Post-Occupancy Evaluation (POE) surveys is paramount in understanding building performance and evaluating building technologies. However, only a small percentage of completed buildings go through a POE. A reason is that clients and non-specialist designers often do not see the value POE can add, and consider it a specialist pursuit. This paper presents ways developed to addres...

On March 13-14, 2006, a meeting on anthrax, sponsored by the Centers for Disease Control and Prevention (CDC) in collaboration with the Southeastern Center for Emerging Biologic Threats, was held at Emory University in Atlanta, Georgia, USA. The meeting's agenda included discussion of postexposure prophylaxis (PEP), screening and evaluation, and treatment of the various manifestations of human ...

File carving is a recovery technique that recovers files based on information about their structure and content without matching file system information. As files can be recovered from their content and/or file structure this technique is indispensable during digital forensics investigations. So far many approaches for the recovery of digital images have been proposed. The main contribution of ...

For the competition of Chinese word segmentation held in the first CIPS-SIGHNA joint conference. We applied a subwordbased word segmenter using CRFs and extended the segmenter with OOV words recognized by Accessor Variety. Moreover, we proposed several post-processing rules to improve the performance. Our system achieved promising OOV recall among all the participants.

We evaluated a 6-week community-based cooking programme, "Eat Better Feel Better", aimed at tackling barriers to cooking and healthy eating using a single-group repeated measures design. 117 participants enrolled, 62 completed baseline and post-intervention questionnaires, and 17 completed these and a 3-4 months follow-up questionnaire. Most participants were female, >45 years, and socioeconomi...
