应用于室内空气过滤的新型过滤介质

论述了关于商用和住宅HVAC、便携式空气净化器和真空吸尘器的最新过滤介质创新技术,利用该技术可达到MERV 16过滤水平而压降低于MERV 10过滤器。与其他商品过滤器相比,由该性能优良的介质制成的便携式空气净化器可使HEPA的CADA提高10%~30%;真空吸尘器使用由新研发的过滤介质制成的过滤器,其性能有极大的提高。     

Bulk analysis with heavy ion beams,calibration

It is shown that for bulk analysis with heavy ion beams, one does not need to know the stopping power of the heavy ions. Instead, hydrogen or helium stopping powers at the same speed, can be used with an accuracy of 1–2%. Also, it is shown that when using Coulomb excitation, the calculated cross-section curve (arbitrary units) is accurate enough to be used for the determination of the average energy when calibrating by the average stopping power method.     

Evaluation of commercial brain–computer interfaces in real and virtual world environment: A pilot study

This paper identifies the user’s adaptation on brain-controlled systems and the ability to control brain-generated events in a closed neuro-feedback loop. The user experience is quantified for the further understanding of brain–computer interfacing. A working system has been developed based on off-the-shelf components for controlling a robot in both the real and virtual world. Using commercial brain–computer interfaces (BCIs) the overall cost, set up time and complexity can be reduced. The system is divided in two prototypes based on the headset type used. The first prototype is based on the Neurosky headset and it has been tested with 54 participants in a field study. The second prototype is based on the Emotiv headset including more sensors and accuracy, tested with 31 participants in a lab environment. Evaluation results indicate that robot navigation through commercial BCIs can be effective and natural both in the real and the virtual environment.
