Robot manipulation tasks like inserting screws and pegs into a hole or automatic screwing require precise tip pose estimation. We propose a novel method to detect and estimate the tip of elongated objects. We demonstrate that our method can estimate tip pose to millimeter-level accuracy. We adopt a probabilistic, appearance-based object detection framework to detect pegs and bits for electric s...

Despite its long history, the classical game of peg solitaire continues to attract the attention of the scientific community. In this paper, we consider two problems with an algorithmic flavour which are related with this game, namely Solitaire-Reachability and Solitaire-Army. In the first one, we show that deciding whether there is a sequence of jumps which allows a given initial configuration...

Engineered nanomaterials promise to transform medicine at the bio-nano interface. However, it is important to elucidate how synthetic nanomaterials interact with critical biological systems before such products can be safely utilized in humans. Past evidence suggests that polyethylene glycol-functionalized (PEGylated) nanomaterials are largely biocompatible and elicit less dramatic immune respo...

This study describes Isophya nagyi sp. n. from the Caliman Mountains (Eastern Carpathians, Romania). This species was discovered on the basis of the special rhythmic pattern of its male calling song. Regarding morphology Isophya nagyi is similar to the species of the Isophya camptoxypha species-group (I. ciucasi, I. sicula, I. posthumoidalis, I. camptoxypha), however the male stridulatory file ...

899 Abstract The maxillary stylets and maxillary palps of three species of mosquitoes belonging to genus Anopheles, viz., Anopheles culicifacies Giles, Anopheles fluviatilis James Anopheles subpictus Grassi have been studied using scanning electron microscope. The studies reveal the presence of lateral teeth and absence of mesial teeth on the maxillary stylets. The number, shape and size of lat...

Parsing Expression Grammars are a popular foundation for describing syntax. Unfortunately, several syntax of programming languages are still hard to recognize with pure PEGs. Notorious cases appears: typedef-defined names in C/C++, indentation-based code layout in Python, and HERE document in many scripting languages. To recognize such PEG-hard syntax, we have addressed a declarative extension ...

In this paper we use a new classification of exchange rate arrangements developed by Reinhart and Rogoff (2002) to test whether reserve holdings decrease with increasing exchange-rate flexibility. Using pooled data for 137 countries over the period 1980-2000, we find several new results. First, the degree of exchange rate flexibility has an inverted-U relationship with the country’s reserve hol...
