Point Counting On Genus 2 Curves
For cryptographic purposes, counting points on the jacobian variety of a given hyperelliptic curve is of great importance. There has been several approaches to obtain the cardinality of such a group, specially for hyperelliptic curves of genus 2. The best known algorithm for counting points on …

Nickel-based superalloy operating temperature determination via analysis of gamma/gamma' microstructure and coating/base material interdiffusion
… The [gamma]' volume fraction was measured by point counting and direct area measurement. The data, however, were found inadequate to accurately determine the operating temperature. The interdiffusion between the platinum aluminide coating and the base material was modeled with an error …

Arithmetic properties and decomposability of Jacobians
… variety in general. Next, we use methods for point counting properties of curves over finite fields to study the decomposability of Jacobians over number fields and finite fields. For example, we show that the genus of curves over number fields whose Jacobians are isomorphic to a product of …

Petrology of sandstones from the Bullion Creek and Sentinel Butte Formations (Paleocene), Little Missouri Badlands, North Dakota
… containing disaggregated sand grains, and 200 points per thin-section were counted, using the Glagolev-Chayes point-counting method. Counts were made of quartz, feldspar, lithic clasts, and accessory minerals. Lithic clasts were further subdivided, and, in decreasing abundance, are chert, …

Exploring the Enstatite Chondrites: Modal Abundances, Metamorphic History, and Volatile Challenges
… analysis of mineral abundances using automated point counting, X-ray diffraction analysis, and XMapTools-based phase mapping. The results reveal significant variations in silicate and sulfide abundances across EC groups, challenging the conventional binary classification and suggesting distinct …

A Petrologic and Diagenetic Study of the Onondaga Formation, New Jersey
… in New Jersey were analyzed using thin section point counting, insoluble residue analysis, X-ray Diffraction, and Scanning Electron Microscopy/Energy Dispersive X-ray microanalysis. These methods gave insight into the lithology, mineralogy, diagenesis, and depositional environment of the …

Comparison of a commercial weight loss program to traditional exercise
… weekly weigh-ins, counseling sessions, and a point counting system to monitor calories. Subjects assigned to TE were instructed to follow the American College of Sports Medicine guidelines for weight loss which included both aerobic and anaerobic exercise a minimum of three times weekly. …

Behaviorally-Induced Structural Remodeling of the Hippocampus
… oriens with Timm’s staining present using grid point counting. There was no significant difference the in the area of Timm’s staining. These findings are consistent with current research, which suggests that there are no significant differences in behavioral learning or axon density immediately …

Facies-driven, seismic inversion-based property modeling, for flow simulation of Delhi Oil Field, Louisiana
… marine and fluvial reservoirs. Mineralogy from point-counting and XRD analysis are integrated with cluster facies logs, core, and seismic data to interpret the depositional environments of each cluster facies. An investigation of bandwidth-extended seismic data demonstrates the ability to detect …

A constitutional study of a dual phase steel containing 12% chromium
… of the various constituents were determined by a point counting method. Transmission electron microscopy was used to study the carbide morphologies and the nucleation and growth modes of the phases during the transformations. The distribution of the alloy elements were determined by microhardness …

Morphological and histochemical observations of hepatic peroxisomes and lysosomes of rats after treatment with methylmercuric chloride, hydrogen peroxide and gamma radiation
… representative micrographs were estimated by point counting. The mean volume densities of hepatic peroxisomes of HP, MMC and I rats fell in the range of 0.94 (+OR-) 0.13 to 1.31 (+OR-) 0.14% of hepatocyte cytoplasm; surface densities ranged from 0.104 (+OR-) 0.013 to 0.127 (+OR-) 0.016 …

Effects of physical and chemical properties of bright and dull coal lithotypes on the formation of char particles
… by scanning electron microscopy using image point-counting techniques. </p><p>PFBR tests and electron microscopy show that lithotype reactivity controls char morphologies, does not influence ash liberation in fluidized bed combustors, but may have an effect in other types of combustion. In …

Sedimentology, facies architecture, and diagenesis of the Middle Three Forks Formation - North Dakota, U.S.A.
… Core descriptions, porosity estimation based on point-counting of forty-seven thin sections, isopach maps of potential "pay zones" throughout northwest North Dakota, as well as a complete lack of hydrocarbon residue in cores, suggest that reservoir quality of the middle Three Forks Formation is …

Diagenesis of the middle member of the Bakken Formation, Williston Basin, North Dakota
… productivity. This study used core samples, point counting, and petrography to determine the diagenetic traits common to the Middle Member of the Bakken Formation and their effect on oil production. Cores from forty-one wells were examined. Thin sections were made from sixteen cores, eight …

Computing the Zeta Function of Two Classes of Singular Curves
… the case of superelliptic curves with singular points that are rational over the field of definition, and the case of nodal projective plane curves. In each case we present, assuming the characteristic is fixed, a polynomial-time algorithm which computes the zeta function the curve, and we …

Geology and petrography of the Wellington Seam, Nanaimo Coalfield, Vancouver Island
… of the coals and mudstones was determined by point-counting at high magnification under incident light in immersion oil. Moisture and ash content, and free swelling index were determined for the coals and mudstones. Seven formations and nine members, comprising the basal half of the Upper …
