A Scalable and Interoperable Platform for Transforming Building Information with Brick Ontology
Rozita Teymourzadeh, Yuya Nakazawa
In the digital twin and building information era, many building automation companies searched for scalable methods to extract and analyze different building data, including Interne…
VLSI Implementation of Cascaded Integrator comb filters for DSP applications
Rozita Teymourzadeh, Masuri Othman
The recursive comb filters or Cascaded Integrator Comb filter (CIC) are commonly used as decimators for the sigma-delta modulators. This paper presents the VLSI implementation, ana…
The Effect of the Digit Slicing Architecture on the FFT Butterfly
Yazan Samir, Rozita Teymourzadeh
Most communications systems tend to achieve bandwidth, power and cost efficiencies to capable to describe modulation scheme. Hence for signal modulation, orthogonal frequency divis…
