Branching patterns are ubiquitous in nature; consequently, over the years many researchers have tried to characterize complexity of their structures. Due hierarchical nature and resemblance fractal trees, they often thought properties; however, non-homogeneity (i.e., lack strict self-similarity) is ignored. In this paper we review examine use box-counting sandbox methods estimate dimensions bra...

We present a unified method for recovering from tracking failure and closing loops in real time monocular simultaneous localisation and mapping. Within a graph-based map representation, we show that recovery and loop closing both reduce to the creation of a graph edge. We describe and implement a bag-of-words appearance model for ranking potential loop closures, and a robust method for using bo...

The timing and temporal order are two characteristic properties that are frequently omitted in machine learning approaches, but carry crucial information. Their consideration is currently limited to algorithms that are specialized to sequential data, but it takes a projection into a vector space to employ the wealth of ML algorithms that are known and understood. Projections inevitably cause a ...

objectives: stuttering is one of the most prevalent speech and language disorders. symptomology of stuttering has been surveyed from different aspects such as biological, developmental, environmental, emotional, learning and linguistic. previous researches in english-speaking people have suggested that some linguistic features such as word meanings may play a role in the frequency of speech non...

resorption of tooth structures can occur as a result of physiological, pathological, and idiopathic factors. early diagnosis and appropriate treatment can prevent its serious complications. this case report presents surgical endodontic management of a trauma-induced perforating external root resorption, which was diagnosed with the help of cone beam computed tomography. following root canal tre...
