In this paper, numerical ranges associated to operators on an indefinite inner product space are investigated. Boundary generating curves, corners, shapes and computer generations of these sets are studied. In particular, the MurnaghanKippenhahn theorem for the classical numerical range is generalized.

the aim of this study is to investigate iranian tefl graduates’ conception of measurement error in research. adopting a sequential explanatory multi-method strategy (borg, 2009), the researchers analyzed causal and temporal relations in the research narratives elicited from 30 tefl graduates. gee’s (1986) framework for identifying narrative discourse units (lines, stanzas, and episodes) was ado...

setback in elevation of a structure is a special irregularity with considerable effect on its seismic performance. this paper addresses multistory reinforced concrete (rc) frame buildings, regular and irregular in elevation. several multistory reinforced concrete moment resisting frames (rcmrfs) with different types of setbacks, as well as the regular frames in elevation, are designed according...

verifying the behavior of shear walls in a tall building requires reliable response results. this paper examined nonlinear fiber element modeling of a slender reinforced concrete shear wall during large-scale shaking table testing. the goal was to understand and validate the inelastic responses given by fiber models using time history analysis. reasonable agreement was found between the numeric...

An introduction is given to basic parts of Clifford analysis including some historical remarks.

In this technical report, we show insights and results of operational data analysis from petascale supercomputer Mistral, which is ranked as 42nd most powerful in the world as of January 2018. Data sources include hardware monitoring data, job scheduler history, topology, and hardware information. We explore job state sequences, spatial distribution, and electric power patterns.
