    Abstract: 一种基于底部阻力分析混凝土和易性的定量评估方法,包括以下步骤:(1)开展新拌混凝土底部阻力测试试验;(2)绘制钢片位移、速度随时间变化曲线;(3)基于底部阻力情况定量评估混凝土和易性;该方法能够通过有效开展新拌混凝土底部阻力测试试验,计算混凝土底部插入速度并绘制位移、速度随时间变化曲线,通过混凝土和易性综合系数定量表征新拌混凝土骨料的沉底情况,从而实现对混凝土和易性的定量评估,克服了传统方法难以定量表征混凝土离析程度的缺陷。

    Abstract: An acoustic system can track gas emissions by exploiting the nostril-accessible nasal pathways of an animal. Actuators and microphones used in the apparatus can be similar to those currently found in cell phones, which in turn make the acoustic apparatus small and rugged. The nostril geometry can be mapped using sound waves, similar to the mapping done by an acoustic rhinometer. Where acoustic rhinometers assume a constant speed of sound to measure changes in geometry, acoustic approaches as disclosed herein can assume constant geometry to measure changes in the speed of sound. Approaches disclosed here are particularly useful with any gas, such as (for example) methane, hydrogen, helium, etc. that has a speed of sound higher than other typical gaseous components of exhaled air, such as nitrogen, carbon-dioxide, oxygen, etc.

    Abstract: An elongated sensor for detecting the presence of a particular fluid includes first and second conductors, both extending from the proximal end to the distal end of the sensor. The second conductor includes a swellable conductor, at least a portion of the swellable conductor is swollen when in contact with the fluid and its conductance at least 10 times less when the portion is in contact with the fluid than when absent contact with the fluid. The second conductor further includes a subsidiary conductor in direct contact with the swellable conductor. In one embodiment the first conductor is isolated from the second conductor in the inner part of the sensor, and the two conductors are electrically connected at the distal end of the sensor. In another embodiment, the first contactor is in direct contact with the subsidiary conductor within the inner part of the sensor.

    Abstract: Safety systems and material testing systems including safety systems are disclosed. An example material testing system includes: an actuator configured to control an operator- accessible component of the material testing system; an actuator disabling circuit configured to disable the actuator; and one or more processors configured to: control the actuator based on a material testing process; monitor a plurality of inputs associated with operation of the material testing system; determine, based on the plurality of inputs and the material testing process, a state of the material testing system from a plurality of predetermined states, the predetermined states comprising one or more unrestricted states and one or more restricted states; and control the actuator disabling circuit based on the determined state.
