Background Staphylococcus aureus is responsible for large numbers of hospital-related and community-acquired infections. In this study, we investigated the presence of S. aureus and methicillin-resistant S. aureus (MRSA) in 100 samples from animals (55 cattle, 36 dogs, and 9 cats) and 150 samples from hospitalized human patients. The samples were collected from healthy and diseased animals and from...
A one degree-of-freedom (vertical up-down) power assist robot was developed for lifting objects. The robot was simulated and six subjects independently lifted objects of three different sizes with the robot. In each trial, the subject used his two hands synchronously to lift the object with the robot and estimated the perceived weight of the lifted object by comparing it to a reference weight. We...
A power assist robot system reduces the weight of an object lifted with it. However, the root causes of the reduced heaviness as well as the factors affecting the heaviness are still unknown. The knowledge on the root causes and factors could be used to modulate the interactions between the human user and the robot when lifting objects with it. This paper investigated the reasons and factors behind...
We conducted two experiments. In the first experiment, we made two objects with identical appearance. One was lifted by humans in constrained condition, another was lifted in unconstrained condition, and human's weight perception was compared between the two conditions. The results showed that weight perception for constrained lifting of objects was not too much different from that for unconstrained...
In this research we present a question answering based searching technique for location based shopping. A user may ask a question to the system as they naturally ask to a human while the system retrieves the search results by analyzing the given question and the current GPS location. Based on the retrieved results, the system carry out conversation with the user to explicitly understand his/her needs...
