This paper presents a method of simulating various noise sources in a Weapons Fire Simulator System which has been modeled as an Optical Communication Channel. This Weapons Fire Simulator System is composed of laser transmitters mounted on weapons that fire blank cartridges, and laser receivers mounted on targets. The laser transmitter sends out 'kill' beam pulses to the target whenever blank cartridges are fired. Detection of these pulses at the target signifies a 'hit'. The entire system along with the optical communication channel is simulated in a general purpose computer program called SCEPTRE. This analysis package is an efficient means of modeling the communication channel characteristics and determining signal to noise ratios as functions of various electrical and physical parameters. Also the SCEPTRE program is a versatile tool for circuit noise calculations. The main advantage is a single SCEPTRE run computes the total noise output from a large number of noise sources distributed throughout the circuit.

The issue of a sceptre for the newly founded Faculty of Science was first discussed on the meeting of Faculty professors on the 25th November 1921, more than a year after the separation of the Faculty of Science from the Faculty of Arts. The commission elected from among the professors proposed a motion that the new Faculty sceptre should resemble the sceptre of the parental Faculty of Arts. Through a mediation of the Ministry of Education and National Enlightment the design of the new sceptre was ordered from the Academy of Arts, Architecture and Design and it was elaborated by prof. Jaroslav Horejc. However, in January 1923, his design was rejected, because it didn't meet the requirements of the professors' conservative approach. When prof. Horejc refused to make a modified copy of the sceptre of the Faculty of Arts, the professors addressed Tengler, the goldsmith who had made the sceptres of other faculties and of the rector in previous years. Alois Tengler was willing to make a modified copy of the sceptre of Faculty of Arts, but he also proposed a new design (with estimated price of 20 000 K), which the professors found more suitable and subsequently this design was adopted. Tengler committed himself to manufacture the sceptre by the 15th November 1924 and to incorporate any additional design...
