— In this paper, we demonstrate a systematic way to determine configurations for up to four coordinated micro-manipulators to form caging grasps for transporting micro-scale planar, polygonal parts. We exploit the geometry of the part, noting the presence and location of convex corners and non-convex corners, and form opposing force equivalents with the(More)
In this paper we demonstrate coordinated control of multiple micromanipulators for use in automated 3D micromanipulation and assembly tasks. We build on our previous work on caging micromanipulation by using a similar methodology and extend it to the 3D case. Simultaneous movements of the coordinated micromanipulators normal to the caging polygon allows for(More)
Objective. To find the location where the human brain cognitive function impairs under hypoxia. Method. 14 healthy males, aged 18-20 years, performed auditory Oddball test of two different intensities (55 dB, 80 dB) during exposure to 5000 m by breathing low oxygen mixture. EEG and Reaction Time (RT) were recorded. P3, the component of ERP, was extracted(More)
Objective. To investigate the effects of sleep deprivation (SD) on human performance. Method. 8 healthy male college students participated the test. During 26 h of continuous awakeness (from 6:00 to 8:00 the next day), the volunteers were demanded to perform a battery of tests at 9 different time (7:00, 12:00, 16:00, 20:00, 0:00, 2:00, 4:00, 6:00, 8:00).(More)
Denial of Service (DoS) or Distributed Denial of Service (DDoS) is a powerful attack which prevents the system from providing services to its legitimate users. Several approaches exist to filter network-level attacks, but application-level attacks are harder to detect at the host base firewall. Filtering in application level can be computationally expensive(More)
