Increasing MTTF requires increasing reliability. In previous lectures we saw a variety of ways to do so: testing, static analysis, formal methods, etc. A highly reliable system is a highly available system. Reducing MTTR requires reducing the (mean) time it takes for the system to come back up once a failure has occurred. Once a failure occurs, we must detect it, diagnose it, and the recover th...
By today, the technology of synthetic aperture radar (SAR) interferometry (InSAR) has been largely exploited in digital elevation model (DEM) generation and deformation mapping. Conventional InSAR technique exploits two SAR images acquired from slightly different angles, in which the information of elevation and deformation can be captured through processing of the phase difference of the image...
Prediction of Channel Availability in Cognitive Radio Networks Using a Logistic Regression Algorithm
Abstract—The capacity of predicting spectral occupancy in cognitive radio networks offers the possibility of developing better policies in channel assignment to secondary users, according to the predicted spectral opportunities. This work develops a prediction model to determine and exploit spectral opportunities while avoiding the continuous search for channel availability in cognitive radio n...
The production process flow in a brewery comprises of various systems and subsystems arranged in series, parallel and combination of these two. The objective of the maintenance department is to achieve maximum Availability without any failure of machine components the plant. The paper discusses the Performance modeling and Availability analysis of a Malt Screener system in brewery plant by usin...
A dynamic cell-matrix interaction is crucial for a rapid cellular response to changes in the environment. Appropriate cell behavior in response to the changing wound environment is required for efficient wound closure. However, the way in which wound keratinocytes modify the wound environment to coordinate with such cellular responses remains less studied. We demonstrated that angiopoietin-like...
The matrix metalloproteinase (MMP) family has been a pharmaceutical target for over 20 years. Despite massive research and development efforts, only one MMP inhibitor (Periostat) has been approved by the FDA for the treatment of periodontal disease. Possible reasons for the low success rate of MMP inhibitors in the clinic include unwanted side effects caused by their lack of selectivity, poor o...
T cells of the vertebrate immune system recognise peptides bound by major histocompatibility complex (MHC) molecules on the surface of host cells. Peptide binding to MHC molecules is necessary for immune recognition, but only a subset of peptides are capable of binding to a particular MHC molecule. Common amino acid patterns (binding motifs) have been observed in sets of peptides that bind to s...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
