Two prototypes of a 9-DoF wheelchair-mounted robotic arm (WMRA) have been developed as assistive devices, consisting of a 7-DoF robotic arm and a 2-DoF power wheelchair. Combined kinematics and redundancy resolution have been previously implemented. In this work, we focus on control methods to allow autonomous mobility and manipulation for the execution of activities of daily living (ADL). Resu...

Psychophysical data have demonstrated that our visual system must integrate multiple, spatially local and non-local cues to construct the visual scene. In this paper we describe a probabilistic network model which integrates visual cues to infer intermediate-level visual representations. We demonstrate the network model for two example problems: inferring “direction of figure” (DOF) [15] and es...

Dof (DNA-binding One Zinc Finger) transcription factor family is unique to plants and has diverse roles associated with plant-specific phenomena, such as light, phytohormone and defense responses as well as seed development and germination. Although, genome-wide analysis of this family has been performed in many species, information regarding Dof genes in the pepper, Capsicum annuum L., is extr...

Objectives were to determine the effects of chromium propionate supplementation on growth performance, insulin and glucose metabolism, and carcass characteristics of beef cattle. Steers ( = 34) were stratified by BW and assigned to 1 of 2 treatments: 1) no supplemental Cr (Cont) or 2) 3 mg supplemental Cr·steer·d (CrP). Both supplements, Cont and CrP, were delivered via 0.454 kg ground corn top...

We demonstrate how two Novint Falcons, inexpensive commercially available haptic devices, can be modified to a create a reconfigurable five-degreeof-freedom (5-DOF) haptic device for less than $500 (including the two Falcons). The device is intended as an educational tool to allow a broader range of students to experience force and torque feedback, rather than the 3-DOF force feedback typical o...

We provide the characterization of the degrees of freedom (DOF) region for a 2-user fading MIMO broadcast channel when perfect channel knowledge is available to the receivers and no channel knowledge is available to the transmitters. The results are applied to find the DOF region for some special cases of a 2-user MIMO interference channel. We also extend the outerbound of the DOF region to fin...

Hyper-redundant manipulation is the use of a hyper-DOF robotic system to accomplish tasks such as picking, placing, reaching, and exploring in challenging environments. Hyper-redundant manipulation involves both finding collisionfree configuration-space paths (the path planning (PP) problem) and transforming a given workspace target pose into a configuration space goal (the inverse kinematics (...

Full-duplex (FD) cellular networks are considered in which a FD base station (BS) simultaneously supports a set of half-duplex (HD) downlink (DL) users and a set of HD uplink (UL) users. The transmitter and the receiver of the BS are equipped with reconfigurable antennas, each of which can choose its transmit or receive mode from several preset modes. Under the no self-interference assumption a...
