Research ArticleOpen accessEvery word in the titleIndoor Navigation to Support the Blind Person Using True Pathway within the MapAbbas M. Ali, Md Jan NordinProblem statement: Map creation remains a very active field in the robotics and AI community, however it contains some challenge points like data association and the high degree of accuracy of localization which are seems to be difficult in some cases, more than that, most of these study focus on the robot navigation, without any consideration for the semantic of … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,832 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleValidating Trace Metals Levels in PM2.5 Aerosols from Indoor and Outdoor Polluting PremisesA. H. Bu-Olayan, B. V. ThomasProblem statement: Our studies revealed high trace metals concentrations in PM2.5 aerosols from Residential Buildings (RB-I) and enclosed Car Parks (CP-I) indoor than in outdoor Residential Buildings (RB-O) and Car Parks Outdoor (CP-O), indicating possible dust accumulation in confined premises from six Kuwait Governorate areas. Approach: Trace metals in PM2.5 was high in the sequence of Bed Room (BR) >kitchen … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,381 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Street Vendors of Bangkok: Alternatives to Indoor Retailers at a Time of Economic CrisisJohn WalshProblem statement: During an economic crisis, consumers will use different techniques to make their money go as far as possible: More carefully comparing prices at point of sale locations, bringing out the coins they previously left unused in saving banks, switching to lower cost options and choosing to shop in less convenient locations in order to find discounts. One such … …American Journal of Economics and Business Administration, Vol. 2, Issue 2 · 30 Jun 2010 · 8,833 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIndoor Navigation and Localization for Visually impaired people Using Weighted Topological MapMd Jan Nordin, Abbas M. AliProblem Statement: Image base methods are a new approach for solving problems of navigations for visually impaired people. Approach: The study introduced a new approach of an electronic cane for blind people using the environment represented as a weighted topological graph instead, each node contains images taken at some poses in the work space, instead of building a metric (3D) … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,420 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIndoor Characterisation using High-Resolution Signal Processing Based on Five-Port Techniques for Signal Input Multiple Output SystemsSmari Mouheddin, Bel hadj Taher JamelProblem statement: The development of wideband mobile communication systems requires a deep knowledge of the characteristics of the indoor mobile radio channel. The characterization of the indoor multi-path propagation structure is important in developing antifading techniques for high-speed digital radio access. The high-resolution of the estimation of the Time of Arrival (ToA) and the Direction of Arrival (DoA) of multi-path … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,684 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFrequency Extended-MUSIC Method for DOA Estimation in Indoor IR-UWB EnvironmentHajer Meknessi, Ferid Harrabi, Ali GharsallahIn recent years, many researchers have been developed in order to ensure an accurate localization. So many techniques have been used the direction of arrival to estimate and track of IR-UWB signals. In this study, we propose a new direction of arrival estimation method for impulse radio UWB signals. This technique based on Extended-Music algorithm. The proposed method has high … …American Journal of Applied Sciences, Vol. 13, Issue 4 · 8 Apr 2016 · 7,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVision Based Reconstruction Multi-Clouds of Scale Invariant Feature Transform Features for Indoor NavigationAbbas M. Ali, Md Jan NordinProblem statement: Navigation for visually impaired people needs to exploit more approaches for solving problems it has, especially in image based methods navigation. Approach: This study introduces a new approach of an electronic cane for navigation through the environment. By forming multi clouds of SIFT features for the scene objects in the environment using some considerations. Results: The system gives … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,220 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Improved Speed-Density Relationship Model for Pedestrian FlowLuthful Alahi Kawsar, Noraida Abdul Ghani, Anton Abdulbasah Kamil, Adli MustafaThe speed-density relationship performs as a basis to realize the behavior of a complex system such as vehicular or pedestrian traffic flow. Based on the speed-density relationship, the relationships between other pedestrian characteristics such as speed-flow, flow-density and speed-pedestrian module could be derived. Compared to vehicular flow, very little research has been done to develop a general model to describe … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 30 Jan 2017 · 7,866 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Passive Opportunity for Improving Air Quality in the Schools Environment: A Real-World Scale TestingPierpaoli Mattia, Fava GabrieleCan passive technology effectively enhance the indoor air quality? To improve classroom indoor air quality, an increase in ventilation and/or air purifiers are often suggested. In this study, a short-term intervention was implemented and investigated to evaluate the effects of a passive adsorbent surface on the pollutant deposition velocity and to improve the overall classroom air quality. We found that … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 3 Jun 2016 · 7,591 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInvestigating the Dynamic Thermal Behavior of Building Envelope in Summer Conditions By Means of in-Field Continuous MonitoringAnna Laura Pisello, Gloria Pignatta, Cristina Piselli et al.The effect of dynamic properties of building opaque envelope in summer conditions is investigated by means of an extensive continuous monitoring of a dedicated experimental field. Two test-buildings, a weather station and two microclimate stations positioned in each test-building represent the experimental field. The prototype buildings have been specifically designed to present the same stationary envelope properties, but different construction … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 25 Apr 2016 · 8,555 accessesView PDFCite
