In this paper, we present a localization of a mobile robot with localization modules which have two ceiling-view cameras in indoor environments. We propose two kinds of localization method. The one is the localization in the local space; we use the line feature and the corner feature between the ceiling and wall. The other is the localization in the large space; we use the natural features such...

Executive Summary The glass ceiling phenomenon that impedes the advancement of talented women professionals into senior executive roles inside large corporations is widely recognized in society, studied in the management literature, taught in business schools, and tangibly felt by many women executives. Outside the corporate setting, we show that a second glass ceiling exists for women entrepre...

The study was conducted to assess the efficacy of an assistive tool to reduce the physical exposures of the ceiling installation task. Based on the idea of using a ‘deadman’ (long narrow piece of panel) to help hold the panels on the ceiling while installing them, a prototype tool was fabricated that could be placed on its own while supporting the ceiling. This tool, which was introduced to the...

Objectives To relieve the financial burden faced by households, the Korean National Health Insurance (NHI) system introduced a "copayment ceiling," which evolved into a differential ceiling in 2009, with the copayment ceiling depending on patients' income. This study aimed to examine the effect of the differential copayment ceiling on financial protection and healthcare utilization, particularl...

Traditionally, diffused infrared configuration has been studied with the assumption that the illuminated region is placed at room ceiling. This is done to ensure minimum path loss to a maximum number of receiver locations. In many practical situations, this arrangement might be difficult to implement, either due to the ceiling structure or the difficulty in illuminating the entire ceiling unifo...

BACKGROUND The results of using status measures to identify any changes in treatment satisfaction strongly suggest a need for specific change instruments designed to overcome the ceiling effects frequently observed at baseline. Status measures may leave little room to show improvement in situations where baseline ceiling effects are observed. A change version of the DTSQ (DTSQc) is compared her...

OBJECTIVE This study was designed to investigate radiographically the effects of age and external irritating stimuli on the morphology and thickness of the pulp chamber ceiling and floor in mandibular molars. MATERIALS AND METHODS A total of 234 panoramic radiographs were recruited and 494 mandibular molars were examined in this study. The sample was divided into six age groups: Group 1, <20 ...

Ceiling shapes for concert halls are proposed that, on the basis of prior extensive subjective evaluations, should result in high listener preference of the hall's acpistoca; response tomusic. These shapes are based on the premise that as little as possible of the early sound energy should arrive at a listener's ears in the "median" plane (the vertical symmetry plane through the listener). Whil...

This paper presents two concurrency control protocols for real-time object-oriented systems. One of the protocols (A ected Set Priority Ceiling Protocol) is designed for single-node systems, and the other (Distributed A ected Set Priorityt Ceiling Protocol) is designed for distributed systems. Both protocols combine features of semantic concurrency control for added concurrency, with priority c...
