A test for behavioral equivalence (2000)
Journal Article
Hou, M., Pugh, A. C., & Hayton, G. E. (2000). A test for behavioral equivalence. IEEE transactions on automatic control, 45(11), 2177-2182. https://doi.org/10.1109/9.887674

External equivalence of behavioral representations is investigated within an impulsive-smooth framework. As an attendant problem, initial-value consistency is also considered. Explicit necessary and sufficient conditions are derived. Applying the ext... Read More about A test for behavioral equivalence.

Observer design based on triangular form generated by injective map (2000)
Journal Article
Hou, M., Busawon, K., & Saif, M. (2000). Observer design based on triangular form generated by injective map. IEEE transactions on automatic control, 45(7), 1350-1355. https://doi.org/10.1109/9.867046

A study is conducted which focuses on showing that for the multi-output case uniform observability is necessary but not sufficient for the existence of a coordinate change bringing a system a triangular form; providing a procedure to construct an inj...

Stark shift in electroluminescence of individual InAs quantum dots (2000)
Journal Article
Itskevich, I., Rybchenko, S., Tartakovskii, I., Stoddart, S., Levin, A., Main, P., Eaves, L., Henini, M., & Parnell, S. (in press). Stark shift in electroluminescence of individual InAs quantum dots. Applied physics letters, 76(26), 3932-3934. https://doi.org/10.1063/1.126825

We have fabricated light-emitting-diode heterostructure devices, in which a layer of InAs self-assembled quantum dots is embedded, with an active area of submicron size. In the electroluminescence spectra of these devices, we observed isolated narrow... Read More about Stark shift in electroluminescence of individual InAs quantum dots.

General solution to systems in polynomial matrix form (2000)
Journal Article
Hou, M., Pugh, A. C., & Hayton, G. E. (2000). General solution to systems in polynomial matrix form. International journal of control, 73(9), 733-743. https://doi.org/10.1080/00207170050029241

Solvability and general solutions to dynamic systems in polynomial matrix descriptions are investigated. The polynomial matrix descriptions need not necessarily be regular. Consistency of initial Values and inputs are discussed. The characterization... Read More about General solution to systems in polynomial matrix form.

Actuation and transduction by giant magnetostrictive alloys (2000)

Since the discovery and understanding of the magnetic properties of the rare earth elements, the transduction properties of magnetostrictive alloys has improved significantly over earlier nickel based alloys. Alongside the advances in permanent magne... Read More about Actuation and transduction by giant magnetostrictive alloys.

Emission lines from individual InAs self-assembled quantum dots (SAQD) have been observed in electroluminescence spectra from small-area p-i-n light-emitting-diode heterostructure devices containing an embedded layer of SAQD. In the energy range whic... Read More about Electroluminescence from individual InAs self-assembled quantum dots.

The effect of stubs on the dynamics of TLM diffusion modeling networks (2000)
Journal Article

The dynamics of stub-loaded, diffusion-modeling transmission line matrix (TLM) nodes are investigated using the TLM-state space analogy. Analysis is performed for one-dimensional and three-dimensional nodes. Additional dynamics are identified and a s...

The standard methods for bringing a TLM diffusion model to convergence are necessary but tedious. However, much time and effort can be saved if the initial choices of elemental size and iteration timestep are appropriate. Here we consider the general...
