A method is presented for autonomous kinematic calibration of the RSI 6-DOF hand controller, a two-loop parallel mechanism comprised of three 6-DOF arms with potentiometers on the first three joints of each arm. This double closed-loop kinematic calibration method is an adaptation of a previously developed single closed-loop method. The kinematic parameters identified are the joint angle offset...

This paper will describe the Diversion OffGate Management Assistant (DOGMA) system, a decision-support tool that uses airline-articulated policies to critique dispatcher initiated diversion decisions to ensure that these plans will not only maintain safe operating practices, but will also go further toward providing decision makers with the broad and diverse set of concerns from various stakeho...

Methods 94 children (46 boys and 48 girls) aged 10-13 years (11.5 ±0.5), were randomly divided into 3 groups. Each group underwent a 6-week therapeutic programme aiming to correct muscles flexibility. The first group-GI (31 children) realized the programme of post isometric muscle relaxation (PIR), the second one-GII (31 children) performed static stretching with stabilization exercises, the th...

In this paper experimentally, the friction-stir welding of the polypropylene sheets with 40% glass fiber has been investigated. Comparison to other welding methods, the strength of the joint is the most important feature in this process. Many parameters such as tool geometry, rotational speed, linear velocity, and tilt angle are very important as input parameters in this type of welding. Theref...

background: functional electrical stimulation (fes) is the most commonly used system for restoring functions after spinal cord injury (sci). objective: in this study we investigated feedback pid and feedforward-feedback p-pid controllers for regulating the elbow joint angle. methods: the controllers were tuned based on a nonlinear muculoskeletal model containing two links, one joint with one de...

in this paper attempts have been done to create a mortar with relatively high uniaxial compressive strength (ucs), easy casting, high flexibility, instant hardening, low cost and easy availability. the main use of this material is to physically model the mechanical behavior of jointed rock-like blocks. the effect of four parameters such as joint roughness coefficient (jrc), bridge length (l), b...

This research effort is undertaken to determine the impact that one hospital’s diversion status has on other hospitals in a region and the strength of these interactions. The conditional probability of one hospital going on diversion given that another is already on diversion is evaluated. Based on this analysis, the strength of interactions among the hospitals is established. Through statistic...

Gait analysis is important in a variety of applications such as animation, healthcare, and virtual reality. So far, high-cost experimental setups employing special cameras, markers, multiple wearable sensors have been used for indoor human pose-tracking gait-analysis purposes. Since locomotive activities walking are rhythmic exhibit kinematically constrained motion, fewer can be employed gait p...

Mayo Clinic has been involved in an ongoing effort to prevent the diversion of controlled substances from the workplace and to rapidly identify and respond when such diversion is detected. These efforts have found that diversion of controlled substances is not uncommon and can result in substantial risk not only to the individual who is diverting the drugs but also to patients, co-workers, and ...
