Stress in the Earth's crust drives earthquakes; therefore, characterizing the state of stress in the crust is essential for mechanistic assessments of seismic risk and hazard. Not only do stresses drive earthquakes, but earthquakes also modify the stress state in the crust by releasing and redistributing the stress in the surrounding crust. This feedback between earthquake and stress occurs over a variety of length and time scales, highlighting the importance of understanding stress before, after, and between earthquakes.Scientific drilling in fault zones provide unique opportunities to study the magnitude of stress around faults and physical properties of rocks in the fault zone. Stress around boreholes induces wellbore failures like breakouts and drilling-induced tensile fractures (DITFs), which allow us to infer the direction and magnitude of the principal

The dwell zones of a shedding cam allow lower strain on the warp sheet compared to linkage driven dobbies for the same warp interference factor. Cam driven dobbies can be designed with dwell zones but they give higher jerk compared to linkage driven dobbies. This work explores the use of six-bar linkages for driving dobbies which will allow the healds to be in near-dwell condition during picking. The healds must be level at the same position in each loom cycle. This requires a mechanism with two nearly equal and symmetrical dwell zones in a crank cycle. The challenges in designing such a mechanism have been outlined in this paper and two possible solutions have been suggested.
