the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...

Achieving the throughput of one wafer per minute per layer with a direct-write maskless lithography system, using 25 nm pixels for 50 nm feature sizes, requires data rates of about 10 Tb/s. In previous work, we have shown that lossless binary compression plays a key role in the system architecture for such a maskless writing system. Recently, we developed a new compression technique Context-Cop...

Background: The clinical data of patients with trigeminal neuralgia who received treatment were retrospectively analyzed, and the surgical strategy for cases without vascular compression was investigated. Methods: Clinical data from 98 patients with trigeminal neuralgia who underwent MVD surgery were retrospectively analyzed. All patients underwent preoperative examinations of 3D-TOF-MRA and 3D...

Compression of recorded ECG data has been a topic of interest since the introduction of computer storage and later Holter monitor applications of ECG recording technology. Compression is typically performed using an approximation algorithm belonging to one of three classes; direct data compression; transformation and parameter extraction. Some debate exists as to how the accuracy of each implem...
