Characterization of the Performance Variation for Regular Standard Cells with Process Non-idealities
… non-idealities. Some research work on 2-D cell characterization shows that the timing variations can be characterized by the timing model. However, as regular design rules become necessary in sub-45 nm node circuit design, 1-D design has shown its advantages and has drawn intensive research …

Design and fabrication of vertical external cavity surface-emitting lasers
… thesis begins with fabrication and experimental characterization of vertical-cavity surface-emitting lasers (VCSELs). After the structure and operation of a VCSEL is overviewed, the fabrication of an oxide-confined VCSEL will be detailed. The VCSEL wafers’ epitaxial structures have a variation in …

Development of MRI-compatible Transducer Array for Focused Ultrasound Surgery: : The Use of Relaxor-based Piezocrystals
… newly specialized FUS material, PZ54 ceramic. A characterization methodology was developed to fully characterize the materials of choice, under ambient and extreme conditions relevant to FUS applications. Practicalities of adopting these materials into FUS were studied by using the characterized …

MEMRISTORS AND NETWORKS: NEW STRUCTURES FOR COMPLEXITY
… design of a hybrid circuit which takes from the characterization methodology of real memristors the idea of using a simple digital linear control circuitry which allows chaos to be observed with the driving of a single memristor. The second part of the thesis focuses on synchronization on complex …

Modelizado y optimización de problemas mecánicos no lineales mediante el Método de Elementos Finitos, RSM y ML
… stresses. These materials require a more complex characterization, which must be carried out through a series of tests followed by a process of adjustment of different strain energy functions. The biggest drawback in this type of procedure is the impossibility of explicitly expressing force values …
