Background: There is a great concern for the possible adverse effects of cell phones’ microwaves. Contradictory results, however, have been reported for the effects of these waves on the body. In the present study, the effect of cell phone microwaves on sperm parameters and total antioxidant capacity was investigated with regard to the duration of exposure and the amount of the frequency of the...

Mobile phone crowdsourcing is a powerful tool for many types of distributed sensing problems. However, a central issue with this type of system is that it relies on user contributed data, which may be sparse or erroneous. This paper describes our experiences developing a mobile phone crowdsourcing app, Kpark, for monitoring parking availability on a university campus. Our system combines multip...

The input data to a topic model is a collection of documents, each of which is represented as a vector of word counts. Even in a noisy environment, relatively little work is required to generate such count vectors from a raw corpus. On the other hand, generating count vectors (or soft–count vectors) over content-bearing features from raw audio data requires considerable effort. In this paper, t...
