The influence of variable-polarization optical
feedback (VPOF) on the polarization mode switching (PMS)
properties of a vertical-cavity surface-emitting laser
(VCSEL) has been investigated experimentally. Rotatedpolarization
optical feedback is considered. At high levels of
optical feedback VCSEL exhibits an abrupt PMS when the
polarization angle is swept from 00 to 900 and vice versa. We
observe a hysteresis loop (HL) beyond the polarization angle
of 450 , which is barely affected by the level of feedback. The
experimental results demonstrate that the size of HL
strongly depends on the feedback level, where a narrower
and wider width HL are observed at higher and lower levels
of feedback, respectively. An external optical feedback with
the VPOF can significantly alter the bistability properties of
PMS in VCSELs. VPOF can provide a new method to
obtain the controllable bistable PMS in VCSELs, which is
extremely useful for applications that use the optical
bistability (OB).

The influence of isolator characteristics on the seismic response of multi-story base-isolated structure is investigated. The isolated building is modeled as a shear type structure with lateral degree-of-freedom at each floor. The isolators are modeled by using two different mathematical models depicted by bi-linear hysteretic and equivalent linear elastic–viscous behaviors. The coupled differential equations of motion for the isolated system

This work demonstrates a highly efficient electrochemical cell based on the hybrid nanofluid of titanium dioxide (TiO 2) nanoparticles dispersed in a water-based copper (II) phthalocyanine-tetrasulfonic acid tetrasodium salt (CuTsPc) solution. A chemical cell of ITO/nanofluid/ITO has been fabricated to study the effect of temperature variations towards its capacitance and resistance. The resultant device showed capacitive sensing mechanism, and the synergistic hybridization of the two different sensing elements lead to the superior performance as compared to the single CuTsPc based device. The hybrid device out-performed the pristine CuTsPc based device in terms of sensitivity, stability, linearity, response/recovery and possessed narrow hysteresis loop.

This paper describes the most important aspects of the second part of a cold formed steel member connections research that is currently being done at the Universidad Nacional de Colombia. In this second stage the behaviour of two different connections are studied,, that is, extended continuity plates connection and side plates connection. This study looks at the results of a finite element analysis of the models, experimental testing on models (cyclic and monotonic tests), analysis and comparison between theoretical and experimental results, hysteretic curves of the connections, approximate calculation of energy dissipation coefficient for structures that use the types of connections studied, and finally, the application of whole results to cold formed steel frames design when these connections are used.

A novel self-sensing and robust control technique is presented for a vanadium dioxide (VO2)-coated silicon (Si) microactuator. The deflection output of the microactuator is estimated by resistance-based self-sensing through a high-order polynomial model in order to eliminate the need for complicated sensing mechanisms. To accommodate the uncertainties produced by the hysteresis between the deflection and the temperature input, and the error in the self-sensing model, an H∞ robust controller is designed and implemented for deflection control. The performance of the robust controller is tested in experiments under step and sinusoidal reference inputs and compared to that of a proportional-integral-derivative (PID) controller. The H∞ controller outperforms the PID controller with 31% and 43% less root-mean-square-error for the step and sinusoidal references, respectively, while maintaining 3.1% less control effort for the latter.
