What is QCM ?
QCM stands for `Query Certi cate Manager'; it is a software system that has been developed at the University of Pennsylvania as part of the SwitchWare project on active networks. QCM is a Public Key Infrastructure (PKI) intended to support secure maintenance of distributed data sets like Access Control Lists (ACL's) or public key certi cate repositories. An ACL is a list of `principals', identi...
متن کاملQCM: A QP-Based Concept Map System
Qualitative representations have proven to be useful formalisms for capturing human mental models. As a result, qualitative modeling could become an important tool for cognitive science. Specifically, an environment in which qualitative representations can be used to explore mental models and different type of reasoning and simulations can be performed on these models can be a useful tool for c...
متن کاملIn situ QCM DNA-biosensor probe modification
We report on a probe modification of a quartz crystal microbalance (QCM) DNA-biosensor that permits to reversibly change the DNA sequence detected. A QCM DNA-biosensor was designed by immobilization of a 20-base DNA-disulfide probe on the gold-covered quartz surface of a 27 MHz microbalance (9 MHz, third overtone). After immobilization on the gold covered quartz surface, this probe was modified...
متن کاملProtein Fibrillation Studied with Qcm-d
The ability of certain polypeptides to aggregate into long, thin fibrils called amyloid structures is associated with multiple protein folding disorders and is also a major problem in biotechnological and pharmaceutical applications. Here, QCM-D has been used to monitor the changes in thickness and viscoelastic properties of multilayer amyloid deposition in situ for the first time. This provide...
متن کاملAnalyzing Spur-Distorted Impedance Spectra for the QCM
The quartz crystal microbalance (QCM) is a sensitive device for determining the properties of materials loading it. One of the fundamental means of making these measurements is the so-called impedance (or admittance) spectra method. The resonant properties of the piezoelectric QCM sensor are measured over a spectral range in the neighborhood of a resonance, both with load and without load. The ...
