Real time control for NASA robotic gripper

Control laws (in some optimal sense) are being developed for the gripper/nut runner end effector. Control laws for the gripper and nut runner portions of the end effector may be developed independently since these two systems are decoupled. A hybrid force/position controller will be used for both the gripper and nut runner. The development of the gripper controller is explained. Sensory data available to the controller is obtained from an array of strain gages as well as a linear potentiometer. Applying well known optimal control theoretic principles, the control which minimizes the transition time between positions is obtained. In addition, a robust force control scheme is developed to contend with the strain gage drift caused by extreme temperature variations encountered in space

Safety profile of oxcarbazepine: results from a prescription-event monitoring study

Purpose: To monitor safety of oxcarbazepine, prescribed in primary care in England, using prescription-event monitoring (PEM). Methods: Postmarketing surveillance using observational cohort technique of PEM. Exposure data were obtained from dispensed British National Health Service prescriptions issued by general practitioners (GPs) March 2000–July 2003. Demographic, drug utilization, and clinical event data were collected from questionnaires posted to GPs at least 6 months after first prescription date for each patient. Incidence densities (IDs) (number of first reports per 1,000 patient-months of treatment) were calculated and differences for events reported in month 1 (ID1) and months 2–6 (ID2–6) (99% confidence intervals) were examined for changes in event rates. Follow-up and causality assessment of medically significant events were undertaken. Results: The cohort comprised 2,243 patients [mean age 40.4 years; range 2–99 years; standard deviation (SD) 18.8; 46.3% (n = 1,038) male]. Most frequently reported primary indications were epilepsy, convulsion (n = 1,111; 49.5%, n = 209; 9.3%, respectively). GPs recorded 932 reasons for stopping medication in 698 (31.1%) patients; most frequent clinical reason “drowsiness/sedation” (n = 57; 2.5% of cohort). Clinical events (excluding indication) associated with starting treatment (lower 99% CI > 0) included: “drowsiness/sedation” (ID1-ID2–6 = 14.2), “nausea/vomiting” (ID1-ID2–6 = 13.0), and dizziness (ID1-ID2–6 = 11.6). Events followed up and assessed as probably related to oxcarbazepine use included rash (7 of 11) and hyponatremia (15 of 38). Discussion:  There were no serious adverse drug reactions reported during this study. Results of the study should be taken in context with other epidemiologic studies

The Distress Thermometer: Validity in a General Cancer Population

This work reports on the psychometric properties of a new measure designed to screen for distress in large populations of cancer patients. The Distress Thermometer (Holland et al., 2000) was tested in a group of 239 heterogeneously diagnosed cancer patients. It was found to be internally consistent (a= 0.86) and to exhibit a reliable eight-factor solution. It displayed acceptable concurrent validity (p ≤ 0.0001) when compared to the Rotterdam Symptom Checklist (deHaes et al., 1994), the Functional Living Index Cancer (Schipper et al., 1984) and the Brief Symptom Inventory (Derogatis, 1993). It was also found to be a sensitive measure of subsyndromal distress

BREAKING CODES: MAKING THEORIES ON MENSTRUATION ACCESSIBLE THROUGH THIRD-WAVE FEMINISM

Men and women respond to situations according to their community’s social codes. With menstruation, people adhere to “menstrual codes”. Within academic communities, people adhere to “academic codes”. This report paper investigates performances of academic codes and menstrual codes. Implications of gender identity and race are missing and/or minimal in past feminist work regarding menstruation. This paper includes considerations for gender identity and race. Within the examination of academic codes, this paper discusses the inhibitive process of idea creation within the academic sphere, and the limitations to the predominant ways of knowledge sharing within, and outside of, the academic community. The digital project (www.hu.mtu.edu/~creynolds) is one example of how academic and menstrual codes can be broken. The report and project provide a broadly accessible deconstruction of menstrual advertising and academic theories while fostering conversations on menstruation through the sharing of knowledge with others, regardless of gender, race, or academic standing
