Magnetic anisotropy of single crystal Ni50.5Mn30.4Ga19.1 having nonmodulated (NM) martensite structure (c=0.660 nm and b=a=0.547 at room temperature) was determined in the range 10–300 K. The variant microstructure needed for proper determination prepared by 40 MPa tensile stress comparison with previous measurements where detwinned obtained compression. process yield easy plane magnetic negligible second constant contrast two constants same order compressed sample. absolute value increases...

We present a corrective model for recovering non-projective dependency structures from trees generated by state-of-the-art constituency-based parsers. The continuity constraint of these parsers makes it impossible them to posit trees. Analysis the types errors made on Czech corpus show that correct governor is likely be found within local neighborhood proposed parser. Our model, based MaxEnt classifier, improves overall accuracy .7% (a 4.5% reduction in error) with over 50% structures.

Digestate is commonly used as a liquid organic fertilizer, it contains nutrients that are important for plant growth and thus help reduce usage of mineral fertilizers. Since the digestate application leads to release greenhouse gases (GHGs) into atmosphere, necessary find suitable method fertilizer rate with minimal gas emissions while providing sufficient crops. The aim this study was investigate relationship between selected GHGs ammonia (NH3) atmosphere different rates applied, i.e., 0,...

The leaf chlorophyll content is a major indicator of plant stress. Therefore, it often used for the evaluation crop status to adjust agricultural management ensure high quality yield while concurrently applying water and agrochemicals in sustainable manner. Since laboratory procedures their assessment are time-consuming destructive, nondestructive methods have been developed recently based on known vegetation spectral response characteristics. In addition various indices derived from...

Measurements of magnetic hysteresis loops in Cu-Al-Mn alloys different Mn content at low temperatures are presented. The smooth and continuous above a certain temperature, but exhibit magnetization discontinuity below that temperature. Scaling analysis suggest this system displays disorder-induced phase transition line. allow one to determine the critical exponents $\ensuremath{\beta}=0.03\ifmmode\pm\else\textpm\fi{}0.01$...

Deformation experiments were performed on three different Fe-4at%Si bicrystals. Synchrotron radiation topography in situ and post mortem was used to investigate the influence of grain boundaries (GB) slip transmission study interaction dislocations with GB. It found that GB forms a strong barrier all cases transfer cannot be fully explained by geometric relations Burgers vectors planes two grains. To explain results internal stresses near due accumulated produced one stopped at image forces...

In this paper we compare two Machine Learning approaches to the task of pronominal anaphora resolution: a conventional classification system based on C5.0 decision trees, and novel perceptron-based ranker. We use coreference links annotated in Prague Dependency Treebank 2.0 for training evaluation purposes. The perceptron achieves f-score 79.43% recognizing personal possessive pronouns, which clearly outperforms classifier is best result reported data set so far.

CoMo/Al 2 O 3 catalyst prepared by impregnation of alumina support with cobalt heteropolyoxomolybdate was tested in hydrodesulfurization (HDS) thiophene, 1-benzothiophene, or light gas oil under various reaction conditions and reactor arrangements. Its physicochemical properties are also examined. The obtained data compared those two industrial HDS catalysts.

We present a new method for automated discovery of inconsistencies in complex manually annotated corpora. The proposed technique is based on Apriori algorithm mining association rules from datasets. By setting appropriate parameters to the algorithm, we were able automatically infer highly reliable annotation and subsequently searched records which inferred violated. show that violations found by this simple are often caused an error. evaluation hand-annotated corpus PDT 2.0, error analysis...

Food production sustainability is one of contemporary agriculture’s fundamental challenges. Farmers are currently facing high input prices in crop and declining organic matter the soil. For this reason, a field experiment was established to assess effect biostimulant NeOsol (NS), manure stabilizer Z’fix (ZF), farmyard (FM), their combination farm practice. In situ measurements provided information on change bulk density (BD), unit draft (UD), saturated hydraulic conductivity (SHC), cone...
