the information is inherently dynamic. Models and displays based on static information (such as histograms of pages requested) will not fully capture the dynamic nature of the underlying web-surfing behavior. Thus, we investigate relatively simple Markov models to represent dynamic behavior. An important point in this context is that these dynamic

The average particle size of PEEK was reduced to 100 μm only after 5 cycles of pan‐milling and reached less than 50 μm after 50 cycles. DSC analysis showed that crystallinity of PEEK decreased with the pan‐milling cycles, agreed with WAXD data. The crystallinity of PEEK decreased from 46.2 to 39.9% of 50 pan‐milling cycles was offered.

In this study, an attempt is made to use the cutting tool's self-excited vibration during a cutting beneficially to generate microtextures. This approach is named as "controlled chatter machining (CCM)." Modal analysis is first performed to study the dynamic behavior of the cutting tool. Turning processes are then conducted by varying the ...

To characterize the path accuracy of a highly dynamic milling machine an autarkic metrology frame was designed which can be integrated on the machine tool. Compared to existing approaches the metrology frame can be used to characterize the dynamic tool path of a 3 axes machine tool without constraints like the limitation to a 2D layer.

On Powder Flowability
During formulation development, the flow of a blend may affect excipient se-lection and may dictate whether direct compression is used or some form of granulation is required. A full under-standing of powder-flow behavior is es-sential when addressing segregation prob-lems. In extreme cases, the success or failure of a product has hinged on its ...
Average Chip Thickness Dictates Milling Performance ...
In any milling application, setting a feed rate that yields the correct average chip thickness for a particular insert is critical. Yet many manufacturers overlook this basic principle, says Todd Miller, manager of rotating products for Seco Tools.The typical result is unexplained problems with premature insert failure, poor surface finish, work hardening, vibration or …

Characterization - Definition and Examples | LitCharts
Direct characterization is also sometimes called "explicit characterization." Indirect Characterization. In indirect characterization, rather than explicitly describe a character's qualities, an author shows the character as he or she moves through the world, allowing the reader to infer the character's qualities from his or her behavior.
