In this paper the simultaneous localization and mapping problem in an unknown indoor environment is addressed. A probabilistic approach based on FastSLAM algorithm and line feature map is described. Experimental results performed with a smart wheelchair in an indoor environment are introduced and discussed. Copyright IFAC 2006 c ©

Econometric busines cycle research (EBCR) combines economic theory and measurement in the study of business cycles, i.e., up and downs in overall economic activity. EBCR has four goals: description, forecasting, policy evaluation and implementation/testing of economic theories. In this paper I assess four EBCR methods: business cycle indicators, simultaneous equations models, vector autoregress...

Will reading habit influence your life? Many say yes. Reading underwater slam for structured environments using an imaging sonar is a good habit; you can develop this habit to be such interesting way. Yeah, reading habit will not only make you have any favourite activity. It will be one of guidance of your life. When reading has become a habit, you will not make it as disturbing activities or a...

This paper presents a system for long-term SLAM (simultaneous localization and mapping) by mobile service robots and its experimental evaluation in a real dynamic environment. To deal with the stability-plasticity dilemma (the trade-off between adaptation to new patterns and preservation of old patterns), the environment is represented at multiple timescales simultaneously (5 in our experiments...

1. The relative synergic stimulating influence of anti-horse serum sensitivity, non-hemolytic streptococcal hyperergy and staphylotoxin intoxication have been determined in connection with rabbits' reaction to simultaneous injections of lens extracts. These three synergic states are increasingly active in the order named. 2. Heterologous lens extract is a much more powerful antigen than is homo...

OBJECTIVE We aimed to examine maternal postpartum complications of twin deliveries according to mode of delivery and investigate the associated risk factors. METHODS This was a retrospective cohort review of twin pregnancies with delivery after 26 weeks at a tertiary teaching hospital (1993-2008). The rates of maternal postpartum complications were compared among vaginal, elective cesarean an...

Introduction: Preterm birth is a public health problem and late preterm birth (deliveries between 34-36 weeks of gestation) accounts for 75% of all preterm births. Antenatal Betamethasone can reduce the severity of respiratory distress in preterm infants and its effect is accepted in 24-34 weeks of gestation. Our goal was to determine the neonatal outcomes of Betamethasone prescription in late ...
