Design of ALU based on Majority Logic for Low Power Applications

Approximate calculations are a new nanotechnology paradigm for improving efficiency and reducing energy use. Most of the logic extends to many contemporary nanotechnological developments and is used for the design of digital circuits in its basic portion (3 input plurality, MV). This paper suggests implementations of additional compressors and ML multiplicators. An additional bit discovery circuit is used for the proposed compressors. The size of the multiplier is calculated by a control factor for the importance of different extra bits. The designs proposed are tested with hardware (for example, time frame and port complexity) as well as with error calculation. These designs have superior performance in terms of area and delay. The validity of the proposed designs is also shown by case tests of the error resistance implementation.

BIOMASS OF SOSNOWSKYI'S HOGWEED AS RAW MATERIAL FOR 2D THE CARBONIC NANOSTRUCTURES OBTAINING

The possibility of the carbonization of the Sosnowskyi's hogweed (Heracléum sosnówskyi) biomass for obtaining the carbonic nanmaterials was studied. The characteristic of component composition is given and the parameters of the superficially-porous structure of plant biomass are established. The isotherms of adsorption and desorption of nitrogen on the surface are studied and it is shown that they relate to the type II according to the IUPAC classification. The distribution of times according to the sizes is investigated and it is established that the basic portion of the pore space of the vegetable raw material forms the mezopors with an average width 3.5 of nm. The specific surface area according to Brunauer-Emmet-Teller is determined, which composed 16.4 m2/g. Using a method of the carbonization of organic materials under the effect of local extremely high temperatures and oxidizers the synthesis of nanocarbonic powders, which are formed under the conditions of the self-propagating high-temperature synthesis (SHS method), was carried out. By the methods of spectral analysis (Raman spectroscopy, X-ray diffractometry) and electron microscopy it is shown that from their morphometric parameters the particles of the obtained carbonized product correspond to 2D nanocarbon in the form of grafenic nanoplates. The low-defect planar surface and the presence of the oxygen-containing terminal groups are the characteristic properties of new product. The specific surface area, which composed 179.1 m2/g, is determined. The specific surface area, which composed 179.1 m2/g, is determined. It is established that the micropores introduce the basic contribution to the specific surface area of nanomaterial on the basis of the Sosnowskyi's hogweed biomass.

Step Detection Algorithm Using Fast Fourier Transformation

Pedestrian Dead Reckoning (PDR) is a core component in pedestrian navigation. Usually, PDR algorithms use the current position and movement information to figure out position in the future in order to accomplish the navigation task. Step detection, as a basic portion of PDR, is significant for the implementation of Pedestrian Navigation. In this paper, a step detection algorithm is designed based on the existing research in the relative area. To improve accuracy, the algorithm involves a Fast Fourier Transformation (FFT) for optimizing. At last, an experiment is conducted for this algorithm, and the error rate of step detection is less than 1%.

ISOLATION OF A FRAGMENT (C3a) OF THE THIRD COMPONENT OF HUMAN COMPLEMENT CONTAINING ANAPHYLATOXIN AND CHEMOTACTIC ACTIVITY AND DESCRIPTION OF AN ANAPHYLATOXIN INACTIVATOR OF HUMAN SERUM

A small fragment of C3, called C3a, which has smooth muscle contracting activity, was isolated by three different methods. At pH 8.6, C3a behaved as cation, and using the Archibald method, its mol wt was determined to be 7000. A specific antiserum to C3a showed the fragment to be antigenically distinct from the rest of the C3 molecule, i.e., the C3b portion. The same antiserum and an anti-whole C3 were able to inhibit the biologic activity of C3a. In addition to anaphylatoxin activity, leukocyte chemotactic activity was shown to reside in C3a. Treatment with trypsin caused the cationic fragment to become anionic and abolished the anaphylatoxin but not the chemotactic activity. C3a fragments with identical biologic activity and comparable cationic properties, as determined by acid disc electrophoresis, were obtained by treatment of C3 with C3 convertase, C3 inactivator complex, trypsin, and plasmin. Thrombin produced a similar C3 fragment which was inactive. It was concluded that C3a corresponds to an unusually basic portion of C3 which may be liberated by attack of a variety of enzymes on a highly susceptible region of the native C3 molecule. C3b was cleaved by trypsin and less efficiently by thrombin or plasmin into two antigenically distinct pieces: the larger C3c fragment corresponding to ß1A and the smaller C3d fragment to α2D of aged serum. The c- and the d-fragments were separated and characterized. Isolated C3a rapidly lost its anaphylatoxin activity when treated with small amounts of a partially purified, thermolabile 10S α-pseudoglobulin of human serum. The conditions of inactivation suggested an enzymatic reaction. The anaphylatoxin inactivator also destroyed the activity of C5-derived anaphylatoxin and of lysyl bradykinin.

DEEP SEISMIC REFRACTION INVESTIGATION IN THE CANADIAN ARCTIC ARCHIPELAGO

During 1962 and 1963, the Dominion Observatory conducted refraction seismic surveys in the islands north of the Canadian mainland. These surveys are part of a project of the Government of Canada to explore the Polar Continental Shelf. The operation consisted of three stationary recording units and a shooting party which traversed the frozen sea in a tractor train. Three refraction‐seismic profiles form a continous section from the Canadian Shield through the Franklinian Geosyncline and the Sverdrup Basin to the Arctic Ocean. Post Devonian sediments in the Sverdrup Basin were found to be 10 km thick. The lower, basic portion of the crust is indicated by a velocity of 7.3 km/sec at a depth of 24 km and the base of the crust at 38 km.
