The results of far field modeling of the wastefield formed by the Sand Island, Honolulu, ocean outfall are presented. A far field model, FRFIELD, was coupled to a near field model, NRFIELD. The input data for the models were long time series of oceanographic observations over the whole water column including currents measured by Acoustic Doppler Current Profilers and density stratification measured by thermistor strings. Thousands of simulations were made to predict the statistical variation of wastefield properties around the diffuser. It was shown that the visitation frequency of the wastefield decreases rapidly with distance from the diffuser. The spatial variation of minimum and harmonic average dilutions was also predicted. Average dilution increases rapidly with distance. It is concluded that any impact of the discharge will be confined to a relatively small area around the diffuser and beach impacts are not likely to be significant.

In a radio frequency (RF) system, it is possible to use variable inductors for providing tunable or selective frequency range. Variable inductors can be implemented by the microelectromechanical system (MEMS) process or by using transistors as switches to change the routing of coils or coupling quantities. In this paper, we investigated the design method of a variable inductor by using MOS transistors to switch the main coil paths and the secondary coupled coils. We observed the effects of different metal layers, turn numbers, and layout arrangements for secondary-coupled coils and compared their characteristics on the inductances and quality factors. We implemented two chips in the 0.18 m CMOS process technology for each kind of arrangement for verification. One inductor can achieve inductance values from about 300 pH to 550 pH, and the other is between 300 pH and 575 pH, corresponding to 59.3% and 62.5%, respectively, inductance variation range at 4 GHz frequency. Additionally, their fine step sizes of the switched inductances are from 0.5% to 6% for one design, and 1% to 12.5% for the other. We found that both designs achieved a large inductance tuning range and moderate inductance step sizes with a slight difference behavior on the inductance variation versus frequency.

In Hungarian, stems ending in a back vowel plus one or more neutral vowels show unusual behaviour: for such stems, the otherwise general process of vowel harmony is lexically idiosyncratic. Particular stems can take front suffixes, take back suffixes or vacillate. Yet at a statistical level, the patterning among these stems is lawful: in the aggregate, they obey principles that relate the propensity to take back or front harmony to the height of the rightmost vowel and to the number of neutral vowels. We argue that this patterned statistical variation in the Hungarian lexicon is internalised by native speakers. Our evidence is that they replicate the pattern when they are asked to apply harmony to novel stems in a ‘wug’ test (Berko 1958). Our test results match quantitative data about the Hungarian lexicon, gathered with an automated Web search. We model the speakers' knowledge and intuitions with a grammar based on the dual listing/generation model of Zuraw (2000), then show how the constraint rankings of this grammar can be learned by algorithm.

A comparative analysis of the varietal variability of the fruits of 71 varieties of apple trees of Altai selection in terms of biochemical composition, according to generally accepted methods using statistical variation analysis based on long-term research, was carried out. Correlations were revealed between the content of chemical elements depending on other characteristics of the fruit and the period of ripening. The average content of soluble dry matter in fruits is from an average 15.5% in summer varieties to a high 16.2–16.3% in varieties with autumn and winter ripening. On average, the content of total sugars in fruits is high and varies insignificantly from 12.7 to 12.9%, the content of titratable acids in fruits is high – 1.0%. The content of ascorbic acid is higher in fruits of varieties with summer ripening and is 24.0 mg / 100 g, with autumn – 19.6 mg / 100 g, with winter – 22.0 mg / 100 g. As a result of selection for the qualitative improvement of fruits apple trees in Altai revealed a negative correlation of the biochemistry of the fetus, depending on its size for all indicators. Fruits of a significant part of varieties created in Altai have good taste, of which 27 have a sugar-acid index of 15–25. The fruits of the varieties Alpek, Altai Velvet, Altai New Year, Altai ruddy, Altai sweet, Gornoaltayskoe, Zolotaya taiga, Pepinka Altai have a very high sugar content of more than 15%, a high value of the sum of sugars – in fruits of 59 varieties from 10.0 to 14.9%. Varieties with high biochemical characteristics are their sources in breeding for improved biochemical composition of fruits.

This study examined the mycological quality of groundwater in Yenagoa metropolis, Bayelsa State, Nigeria. Triplicate water samples were obtained from 8 locations in the metropolis, and the fungi quality analyzed following standard microbiological procedures. Results showed that total fungi density ranged from 5.2±1.00 x102 to 8.50±0.56 x103 CFU/ml. Analysis of variance indicates statistical variation (p=0.001) across locations with total fungi density exceeding the limit of 102 CFU/ml specified by World Health Organization/Food and Agricultural Organization for potable water in 62.50% of samples. Eight fungi isolates (species) were identified in the study with frequency across the locations as follows: Aspergillus flavus (20.59%), Aspergillus fumigatus (20.59%), Aspergillus niger (20.59%), Cladosporum (5.88%), Fusarium (2.94%), Mucor (8.82%), Penicilium (14.71%) and Rhizopus (5.88%). Of these, Aspergillus species were predominant across the locations. Since groundwater meets diverse purposes, it is essential that it is suitable for the desired use, and this can be done using appropriate technology to make groundwater potable for human consumption.

Chromatic and achromatic (AC) assessments of camouflage textiles have been critical to the defense researchers for concealment, detection, recognition, and identification (CDRI) of target signature against multidimensional combat background (CB). AC assessment and camouflage measurement techniques are simulated and experimented for assessment of camouflage textiles against CB. This model has been demonstrated for color measurement spectrophotometer, scanning electron microscopy (SEM), digital imaging, hyperspectral imaging, and image processing software (ImageJ) for the advancement and establishment of AC camouflage textiles assessment. The chromatic variations of 48 artificial target objects (TOBs) have been synthesized by image processing; the technique can be implemented for defense CB-CDRI assessment. Microstructural variation versus optical signal of woodland, desertland and stoneland CB materials have been elucidated by SEM magnification. The achromatic variation of CB materials have been demonstrated for the replacement of optical signal against modern remote sensing device to the imaging sensor. Color difference (Δ E), microstructural variations, pixel variations to imaging signal and standard deviation of CB materials have been represented for remote sensing surveillance of defense applications against TOB-CB-CDRI. Technical simulation of color, texture, gloss, and pixel intensity has been derived for AC-CDRI assessment of camouflage textiles in TOBs-CB environment.
