LOW-POWER PROGRAMMABLE PRPG WITH TEST COMPRESSION CAPABILITIES

This paper describes a new programmable low power test compression method that allows shaping the test power envelope in a fully predictable, accurate, and flexible fashion by adapting the existing logic BIST infrastructure. The proposed hybrid scheme efficiently combines test compression with logic BIST, where both techniques can work synergistically to deliver high quality test. Experimental results obtained for industrial designs illustrate feasibility of the proposed test scheme and are reported herein

Publication trends in the medical informatics literature: 20 years of "Medical Informatics" in MeSH

<p>Abstract</p> <p>Background</p> <p>The purpose of this study is to identify publication output, and research areas, as well as descriptively and quantitatively characterize the field of medical informatics through publication trend analysis over a twenty year period (1987–2006).</p> <p>Methods</p> <p>A bibliometric analysis of medical informatics citations indexed in Medline was performed using publication trends, journal frequency, impact factors, MeSH term frequencies and characteristics of citations.</p> <p>Results</p> <p>There were 77,023 medical informatics articles published during this 20 year period in 4,644 unique journals. The average annual article publication growth rate was 12%. The 50 identified medical informatics MeSH terms are rarely assigned together to the same document and are almost exclusively paired with a non-medical informatics MeSH term, suggesting a strong interdisciplinary trend. Trends in citations, journals, and MeSH categories of medical informatics output for the 20-year period are summarized. Average impact factor scores and weighted average impact factor scores increased over the 20-year period with two notable growth periods.</p> <p>Conclusion</p> <p>There is a steadily growing presence and increasing visibility of medical informatics literature over the years. Patterns in research output that seem to characterize the historic trends and current components of the field of medical informatics suggest it may be a maturing discipline, and highlight specific journals in which the medical informatics literature appears most frequently, including general medical journals as well as informatics-specific journals.</p

PAD is the best inhibitor and IE% can be classified in the following order: PAD> PPD > PTD > DMA > AL. The effect of temperature (range 303-333 K) on the corrosion behaviour of mild steel in plain HF solution and inhibited acid was also studied. The corrosion rate increased with increasing temperature both in uninhibited and inhibited acid and the values of IE% of all the inhibitors depend on temperature. The inhibitors act as mixed adsorption type inhibitors. Adsorption of AL, DMA and PTD on mild steel in 3% HF interface corresponds to Langmuir adsorption isotherm model while PAD and PPD appear to adsorb on the metal surface according to Temkin adsorption isotherm.</span

Corrosion inhibition of N80 steel in hydrochloric acid by phenol derivatives

501-506The inhibitory action of methoxy phenol (MPH) and nonyl phenol (NPH) on corrosion of N80 steel in 15% HCl has been investigated at different period of exposure (6 to 24 h) and temperature (30 to 110°C). Nonyl phenol and methoxy phenol have shown maximum inhibition of about 83 and 78% at 75 mM inhibitor concentration in the acid respectively after 6 h exposure test at ambient temperature. The inhibition efficiencies of nonyl phenol and methoxy phenol are found to be about 79 and 30% respectively after 24 h exposure. Nonyl phenol has shown maximum inhibition of about 59 and 44% at 75 mM inhibitor concentration in the acid respectively at 90 and 110°C respectively. The inhibition afforded by methoxy phenol was found to be relatively low (about 34% at 60°C). Heat of adsorption was found to be 50 KJ/mol in case of MPH, indicating formation of a protective chemisorbed film on the metal surface, which suppresses the dissolution reaction. NPH showed heat of adsorption of about 26 KJ/mol indicating a weak chemisorption. Both these compounds inhibit corrosion by adsorption mechanism and follow Temkin isotherm. The results of polarization studies indicate that the compounds are mixed type inhibitors. The FTIR spectral analyses of the surface product suggest involvement of hydroxyl group (un protonated as well as protonated) of these inhibitor molecules in the adsorption process

Study on corrosion control of N80 steel in acid medium using mixed

221-227Effects of inhibitor mixtures (TVE-3A, TVE-3B and TVE-3C) containing formaldehyde in combination with phenol or cresol on corrosion behaviour of N80 steel in 15% HCl solution were investigated using weight loss and potentiostatic polarization technique. The influence of temperature (30-115°C) and time interval (6-24 h) in the absence and presence of inhibitors on corrosion of the steel in the acid has been studied. TVE-3B has shown the maximum inhibition of 68.6% at ambient temperature whereas maximum inhibition shown by TVE-3A and TVE-3C was found to be 62.2% and 65.7% respectively. The inhibition efficiency was found to gradually decrease with increase in temperature in the case of TVE-3A while TVE-3B and TVE-3C showed a further increase in the protection at higher temperatures (about 81% at 115°C). The protective efficiency of TVE-3B and TVE-3C is comparable with Grade-III (about 88% at 115°C) commercial inhibitor. Inhibition of corrosion is due to adsorption of inhibitors on the metal surface. The adsorption is found to obey Frumkin isotherm. FTIR study of the metal surface products after the corrosion inhibition tests reveal presence of non-linear poly phenyl species, no free carbonyl group indicating formation of a cross linked and three dimensional networking resulting in novalac resin or bakelite by condensation polymerization (acid catalyzed). Oxygen atom, (of –OH group in phenol or substituted phenol) may coordinate to Fe²⁺ on the metal surface resulting in a protective inhibitor layer. Thermal stability of the inhibitor mixtures was determined by DSC, which has shown that the compounds present in TVE-3A vaporize with increase in temperature while the compounds present in the case of TVE-3B and TVE-3C are thermally stable up to 200°C
