    • Situational Judgement Selection Test Utility: Implications for Police Turnover 

      Jones, Marshall Alan (2019-07)
      Police agencies increasingly find attracting, recruiting, selecting, and retaining police officers challenging. Officer candidates selected can have up to a 25 percent fail rate in basic police training, while probationary ...
    • Skin Deformation Feedback for Force Sensory Substitution in Teleoperation and Virtual Reality Training 

      Schorr, Samuel (2017-08-28)
      For this work, we developed a wearable skin deformation device that is worn on the tip of the finger. The devices have two separate components, the first of which is a finger grounding interface that straps to the medial ...
    • Small satellite launch capability of the Boeing Inertial Upper Stage 

      Platt, Donald W.; Antalek, Christopher; Bocchicchio, Jennifer D.; Katz, Dale; Keleshian, Greg; Martin, Paul (1997-09-19)
      We present a design for taking advantage of the Boeing inertial upper Stage (IUS) to provide a means of launching small satellites as passengers on a Titan IV-IUS launch of a 1775 kg communications satellite. An overview ...
    • Small-scale magnetic flux ropes in the solar wind 

      Moldwin, M. B.; Ford, S.; Lepping, Ronald P.; Slavin, James A.; Szabo, Adam (2000-01-01)
      Small-scale magnetic flux ropes have been discovered in the solar wind at 1 AU in observations from the IMP 8 and WIND spacecraft. These small magnetic structures (diameter of 270 R(E), on average) have some similar ...
