The Python programming language is becoming increasingly popular in a variety of areas, most notably among novice programmers. This paper presents an implementation of Python for DrRacket which allows Python programmers to use DrRacket’s features with Python code, as well as adding Python support for DrRacket based tools, such as Rosetta. The suggested approach involves compiling Python code in...
In this paper, we develop a robotic table tennis system in the case of the back spin with the same measurement method and the ball models of the aerodynamics and the rebounds as in the study of Nakashima et al. (2011). First, the aerodynamics model is improved for precise prediction of the ball trajectory with data of the flying back-spin ball. Second, a method to determine the racket motion is...
While volatile marketing spending, as opposed to even-level spending, may improve a brand’s financial performance, it can also increase the volatility of performance, which is not a desirable outcome. This paper analyzes how revenue and cash-flow volatility are influenced by own and competitive marketing spending volatility, by the level of marketing spending, by the responsiveness to own marke...
Non–traditional parties have had newfound success across European democracies contributing to increasing electoral volatility. Drawing from the literature on social movements, voting for an unconventional party can be a form of contentious politics. Support for non– mainstream parties is the institutional manifestation of the factors that contribute to social movements. Perceptions of political...
— We consider the comovement of economic volatility across multiple countries. Using spatial models with data from 187 countries over the period of 1960–2007, we find a strong spatial comovement of economic volatility. More interestingly, the effect of geographical proximity on economic volatility comovement is strongest during the period of international shocks (1973–86), but almost disappears...
Blood samples were collected from the jugular vein of 101 clinically healthy Iranian fat-tailed sheep according to their age (5 years) and sex. Serum haptoglobin (Hp) was measured based upon the preservation of the peroxidase activity of haemoglobin, which is directly proportional to the amount of Hp. The reference value for serum Hp of apparently healthy Iranian fat-tailed sheep was 0.05-0.18 ...
Sports analysis has recently become popular in research and professional applications. This paper presents a scheme for automatic sports video analysis based on audio clues and specific game context knowledge. We propose a simple, two-step racket-hit detection for achieving accurate event classification for tennis video. To implement the mapping between the sample-level feature space and the se...
Given the sophistication of recent type systems, unification-based type-checking and inference can be a time-consuming phase of compilation—especially when union types are combined with subtyping. It is natural to consider improving performance through parallelism, but these algorithms are challenging to parallelize due to complicated control structure and difficulties representing data in a wa...
