Andrology laboratories need to produce reliable results for appropriate diagnostic and health care decisions. Since semen analysis is highly complex and procedurally difficult to standardize, quality control (QC) is essential to detect and correct systematic errors and high variability of results. The large discrepancies between assessments of sperm concentration and morphology in different lab...

Mohammad-Karim Pirnia, one of the most prominent scholars of the history of Iranian architecture, has recorded two major achievements: the principles of Iranian architecture and the stylistics of Iranian architecture. In this article we will discuss his suggested principles for Iranian architecture. For this purpose, we will first show how his five principles have evolved and completed th...

The effect of brickworks emissions on heavy metal content of soil and plants around the brick kiln chimneys was studied in the year 2006. Two brick kilns (A and B) about 600 m away from Ring Road at SufaidDheri on southerrn side of Peshawar, Pakistan were selected for this study. The two bricks kilns were North-South to each other with 300 m distance in between, such that South direction from b...

We propose an algorithm based on singular value decomposition (SVD) to reduce the number of process variation variables. With few process variation variables, fault simulation and timing analysis under process variation can be performed efficiently. Our algorithm reduces the number of process variation variables while preserving the delay function with respect to process variation. Compared wit...

High accuracy complex computer models, also called simulators, require large resources in time and memory to produce realistic results. Statistical emulators are computationally cheap approximations of such simulators. They can be built to replace simulators for various purposes, such as the propagation of uncertainties from inputs to outputs or the calibration of some internal parameters again...
