Introduction: Amelia Jones

Amelia

Amelia was built by Real World Interface (RWI) using Xavier-a mobile robot platform developed at CMU on a B24 base from RWI-as a prototype. Amelia has substantial engineering improvements over Xavier. Amelia is built on a B21 base. It has a top speed of 32 inches per second, while improved integral dead-reckoning insures extremely accurate drive and position controls. The battery life is six ho...

Tetra-Amelia Syndrome

A newborn was noticed lying unattended in the hospital campus. It had complete absence of all four limbs, deformed ears, facial cleft, proptosis, hydrocephalus, corneal opacity, absent nipples, anterior abdominal wall defect with exstrophy bladder, absent external genitalia, and sacral spina bifida (Fig.1 A & B). The child died after few hours due to aspiration pneumonitis. These features are p...

Lecture 5 : Introduction to ( Robertson / Spärck Jones ) Probabilistic Retrieval

In this lecture, we will introduce our second paradigm for document retrieval: probabilistic retrieval. We will focus on Roberston and Spärck Jones’ 1976 version, presented in the paper Relevance Weighting of Search Terms. This was an influential paper that was published when the Vector Space Model was first being developed — it is important to keep in mind the differences and similarities betw...

Fetal amelia: a case report.

Congenital limb defects are rare fetal anomalies with a birth prevalence of 0.55 per 1,000. Amelia is an extremely rare birth defect marked by the complete absence of one or more limbs. We report a case of fetal amelia, ultrasound findings, manifestations and the fetal outcome.
