One important difference between industrial robotic manipulators and service robot applications is the human interaction, which introduce safety and comfort constraints. In this paper, we define soft motions conditions to facilitate this cohabitation. We propose an on-line trajectory planner that generates the necessary references to produce soft motion and a control loop that guarantees the en...

PURPOSE This study evaluated the clinical performance of KeraSoft(®) IC (KIC) soft contact lenses in subjects with irregular corneas. PATIENTS AND METHODS This was a 12-month, prospective, open-label, observational study, which enrolled 43 subjects who were 18 years of age or older with irregular corneas. Subjects were fit according to the KIC Fitting Manual (kerasoftic.com). After achieving ...

BACKGROUND The aim of the study was to examine the clinical success of high Dk (oxygen permeability) piggyback contact lens (PBCL) systems for the correction of contact lens intolerant keratoconus patients. METHODS Sixteen patients (29 eyes) who were not able to wear gas-permeable rigid lenses were included in this study. Hyper Dk silicone hydrogel (oxygen transmissibility or Dk/t = 150 units...

Background: Creating a socket with proper fit is an important factor to ensure the comfort and control of prosthetic devices. Several techniques are commonly used to cast transtibial stumps but their effect on stump shape deformation is not well understood. This study compares the dimensions, circumferences and volumes of the positive casts and also the socket comfort between two casting method...

Background: Hospitalized patients with Covid-19 may experience emotional problems and respiratory discomfort during mechanical ventilation. The aim of this study was to evaluate the effects of music therapy on respiratory comfort, anxiety, and depression among patients with Covid-19 under non-invasive mechanical ventilation. Methods: It was a randomized clinical trial. The subjects were 64 pat...

Received signal strength indicator plays a very important role in many WLAN applications. However wireless signal strength will be greatly affected by noise and disturbance. It is critical to remove the abnormal data in order to provide a reliable estimation of the received signal strength indicator. Conventional mean value based approaches require large amount of data which would lead to unrel...

We investigate strategic information transmission with communication error, or noise. Our main finding is that adding noise can improve welfare. With quadratic preferences and a uniform type distribution, welfare can be raised for almost every bias level by introducing a sufficiently small amount of noise. Furthermore, there exists a level of noise that makes it possible to achieve the best pay...
