While manufacturing test helps to isolate faulty devices from the good ones, diagnosis is enabling a faster transition from the yield learning to the volume production phase of a new process technology. Given the escalating design complexity, new methods such as embedded deterministic test have been proposed in recent years to deal with the cost of manufacturing test. This paper discusses diagnosis of logic blocks by leveraging the existing embedded deterministic test hardware. The proposed method is based on new techniques for on-chip decompression and comparison of incompletely specified test patterns and test responses. Using experimental data, the tradeoffs between the number of tester channels, on-chip area, and scan time are discussed. 相似文献

The VCR Plus+ is a remote control for programming video cassette recorders. It uses an encrypted 1 to 8 digit number that encodes the channel, start time, length, and day of the month of the television show to be recorded. This paper describes a procedure for decoding the 1 to 6 digit codes. 相似文献

Raw materials selection and method of synthesis determine the type of branching in a commercial branched fatty acid. The type
of branching plus the isomer distribution, the normal chain/branched chain ratio, the chain length distribution, and the purity
of the acid determine the physical properties of commercial branched acids. The latter four characteristics are affected by
postsynthesis processing of the crude branched acids using such standard manufacturing or finishing techniques as distillation,
solvent separation, hydrogenation, and bleaching. The generally lower titers or pour points of branched acids and their derivatives
combined with their different (relative ton-chain materials) solubilities and their generally good heat and oxidative stabilities make them useful in applications in
such diverse areas as soaps, cosmetics, lubricants, plastics, and coatings among others. The physical and usage properties
which branched acids effect inproducts in such areas are often very different from the physical and usage properties which
straight chain acids (which are also used in the same areas) effect. Thus, the use of branched acids gives an increased range
of formulation possibilities and greater flexibility to product developers and formulators. 相似文献

Methane output and lactation response in Holstein cattle with monensin or unsaturated fat added to the diet 总被引:1,自引:0,他引:1

We measured effects of continuous vs twice-daily feeding, the addition of unsaturated fat to the diet, and monensin on milk production, milk composition, feed intake, and CO2-methane production in four experiments in a herd of 88 to 109 milking Holsteins. Methane and CO2 production increased with twice-daily feeding, but the CO2:CH4 ratio remained unchanged. Soybean oil did not affect the milkfat percentages, but fatty acid composition was changed. All saturated fatty acids up to and including 16:0 decreased (P < .01), whereas 18:0 and trans 18:1 increased (P < .001). The 18:2 conjugated dienes also increased (P < .01) when the cows were fed soybean oil. Monensin addition to the diet at 24 ppm decreased methane production (P < .01); the CO2:CH4 ratios reached 15, milk production increased (P < .01), and milkfat percentage and total milkfat output decreased (P < .01), as did feed consumption, compared with cows fed diets without monensin (P < .05). Milk fatty acid composition showed evidence of depressed ruminal biohydrogenation: saturated fatty acids (P < .05) decreased and 18:1 increased (P < .001); most of the increase was seen in the trans 18:1 isomer. As with soybean oil feeding, addition of monensin also increased (P < .05) the concentration of conjugated dienes. The monensin feeding trial was repeated 161 d later with 88 cows, of which 67 received monensin in the diet in the first trial and 21 cows were newly freshened and had never received monensin. Methane production again decreased (P < .05), but this time the CO2:CH4 ratio did not change and all other monensin-related effects were absent. The ruminal microflora in the cows that had previously received monensin seemed to have undergone some adaptive changes and no longer responded as before. 相似文献

The color stability of fresh ground veal from four different muscles (biceps femoris, longissimus dorsi, psoas major and supraspinatus) was characterized, and the effects of lipid oxidation, iron and zinc on this degradative process were investigated. Samples were minced and prepared in a manner consistent with retail production and analyzed for pH, myoglobin concentration, total and nonheme iron, and zinc. Pigment and lipid oxidation were measured on days 0, 3 and 6 of 4°C storage. B. femoris demonstrated the greatest extent of lipid oxidation, and was more color-labile than p. major or supraspinatus (P < 0·05), but no different from l. dorsi (P > 0·05). Total iron and myoglobin concentrations were lowest for l. dorsi (P<0·05). Zinc concentration in the four muscles followed the order supraspinatus ? b. femoris ? l. dorsi ? p. major (P < 0·05). Data analysis revealed that initial metmyoglobin formation (days 0 to 3) was significantly correlated with total iron (r = 0·69) or nonheme iron (r = 0·68) in b. femoris, but not any of the other muscles. Correlations between lipid and pigment oxidation in each of the four muscles were performed and the data support a strong relationship between these degradative processes in ground veal. 相似文献

Thermionic electron emission microscopy was used to measure directly the thickening kinetics of proeutectoid ferrite sideplates
in Fe-C alloys. These kinetics were found to be exceedingly irregular. During the first few seconds of growth, the thickening
rate is 5 xl0-5±1 cm/s; afterwards it usually diminishes to 1 - 30 × 10-6 cm/s. As predicted by a general theory of precipitate morphology, thickening was shown to occur only by the ledge mechanism,
despite the relatively poor matching of the austenite and the ferrite lattices. Ledges were observed to lengthen at rates
controlled by the diffusion of carbon in austenite. Tent-shaped and other more complex surface relief effects, rather than
the invariant plane strain relief, were found to predominate. These features are shown to be the expected result of a diffusional
transformation occurring by means of a ledge mechanism.
