Simple Pendulum Revisited

We describe a 8085 microprocessor interface developed to make reliable time period measurements. The time period of each oscillation of a simple pendulum was measured using this interface. The variation of the time period with increasing oscillation was studied for the simple harmonic motion (SHM) and for large angle initial displacements (non-SHM). The results underlines the importance of the ...

A fast floating-point square-rooting routine for the 8080/8085 microprocessors

Square-root is a function for which numerous numerical methods have been developed. In most math packages for microprocessors, simple iterative methods have been used, as no special demands for speed — nor even for accuracy in some cases are expected: e.g. in [ l ] and [2] the execution time of square-rooting is approx. 2-5 times longer than that of multiplication, and in [3] a quintuple error ...

Downregulation of the stress-induced ligand ULBP1 following SV40 infection confers viral evasion from NK cell cytotoxicity

Polyomaviruses are a diverse family of viruses which are prevalent in the human population. However, the interactions of these viruses with the immune system are not well characterized. We have previously shown that two human polyomaviruses, JC and BK, use an identical microRNA to evade immune attack by Natural Killer (NK) cells. We showed that this viral microRNA suppresses ULBP3 expression, a...

CAD tool for the automatic generation of microprograms

A methodology for automatic synthesis of microprograms for digital systems modeled in the UAHPL register-transfer-level language is described. The algorithms used in the process of translation from UAHPL description to microprograms are also discussed. Since the UAHPL model is directly related to hardware, this approach is better than those based on ordinary high-level languages or special micr...
