Recracking of jointed rock masses in the Sydney Basin, New South Wales, Australia

Fracture mapping of Late Permian – Early Triassic flat-lying sedimentary rocks in the Sydney Basin, New South Wales, Australia, shows that joints developed originally in extension were faulted in subsequent events. Joints with a regional distribution fall into two, early and late formed groups. Group I joints propagated horizontally and never interfered with each other. These joints were subsequently reworked or recracked. Recracking commenced with jointing and continued with lateral slip. Faulted joints grew horizontally by linking of recracked segments. En echelon arrays are the result of vertical propagation of faulted joints into intact rock. Recracking of rock also resulted in the formation of sets of secondary joints (Group II). The sense of movement on conjugate faulted joints and orientation of sets of secondary joints, are related to three compressional stress fields. The intensity of recracking and the amount of lateral slip is mostly related to the strength of infilling materials, the length and continuity of parent joint, the angle between the existing fractures and the maximum compression direction, and the number of compressional events imposed on the fracture.
Online State of Charge Estimation for Lithium-Ion Battery by Combining Incremental Autoregressive and Moving Average Modeling with Adaptive H-Infinity Filter

The state of charge (SOC) estimation is one of the most important features in battery management system (BMS) for electric vehicles (EVs). In this article, a novel equivalent-circuit model (ECM) with an extra noise sequence is proposed to reduce the adverse effect of model error. Model parameters identification method with variable forgetting factor recursive extended least squares (VFFRELS), which combines a constructed incremental autoregressive and moving average (IARMA) model with differential measurement variables, is presented to obtain the ECM parameters. The independent open circuit voltage (OCV) estimator with error compensation factors is designed to reduce the OCV error of OCV fitting model. Based on the IARMA battery model analysis and the parameters identification, an SOC estimator by adaptive H-infinity filter (AHIF) is formulated. The adaptive strategy of the AHIF improves the numerical stability and robust performance by synchronous adjusting noise covariance and restricted factor. The results of experiment and simulation have verified that the proposed approach has superior advantage of parameters identification and SOC estimation to other estimation methods.
Design procedure for pot-core integrated magnetic component

The side-by-side (primary-secondary) wound integrated magnetic component is often used to combine series inductance and transformer behaviour in LLC resonant converters and dual active bridge converters. This paper presents an easy to follow design procedure for this component, translating the component's electrical specification into a physical design. A combination of reluctance modelling, the application of Ampere's law and the introduction of an alignment factor, obtained through finite element analysis, is used to derive a model for the integrated magnetic component. The model is encapsulated within a design approach accounting for frequency, maximum operating flux density, etc., to ensure the final component is not oversized and meets the design specification.
Numerical experiments on plasma focus neon soft x-ray scaling

Numerical experiments are carried out systematically to determine the neon soft x-ray yield Ysxr for optimized neon plasma focus with storage energy E0 from 0.2 kJ to 1 MJ. The ratio c = b/a, of outer to inner electrode radii, and the operating voltage V0 are kept constant. E0 is varied by changing the capacitance C0. Parametric variation at each E0 follows the order operating pressure P0, anode length z0 and anode radius a until all realistic combinations of P0, z0 and a are investigated. At each E0, the optimum combination of P0, z0 and a is found that produces the biggest Ysxr. At low energies the soft x-ray yield scales as whilst towards 1 MJ it becomes . The Ysxr scaling laws are found to be (0.1–2.4 MA) and (0.07–1.3 MA) throughout the range investigated. When numerical experimental points with other c values and mixed parameters are included, there is evidence that the Ysxr versus Ipinch scaling is more robust and universal, remaining unchanged whilst the Ysxr versus Ipeak scaling changes slightly, with more scatter becoming evident.
Base temperature for node emission and plastochron determination in tomato species and their hybrids

The objective of this work was to estimate the base temperature for node emission and plastochron determination in wild species of tomato, in the Redenção cultivar, and in their respective interspecific F1 hybrids. The wild accessions Solanum pimpinellifolium AF 26970, Solanum galapagense LA-1401, Solanum peruvianum AF 19684, Solanum habrochaites var. hirsutum PI-127826, Solanum habrochaites var. glabratum PI-134417, and Solanum pennellii LA-716; the cultivar Redenção (Solanum lycopersicum); and their respective interspecific hybrids were evaluated, on the transplanting dates 12/22/2015, 2/12/2016, and 4/6/2016. The base temperature was estimated using the least mean squared error of the linear regression between the number of nodes and the accumulated thermal sum. The plastochron for the main stem and the first three lateral stems was estimated using the base temperature. The base temperature for node emission and plastochron determination varied from 4.5 to 14.8°C. The species S. habrochaites var. hirsutum accession PI-127826, S. habrochaites var. glabratum accession PI-134417, and their hybrids with the Redenção cultivar showed the lowest base temperatures and plastochron for the main stem, whereas the remaining wild species and interspecific hybrids had a base temperature near that of cultivated tomato. Wild species and interspecific hybrids of tomato show a great variation in base temperature for node emission and plastochron determination.
Analysis of PC 6 window function using fractional Fourier transform

Fourier transform (FT) is one of the most valuable tools in signal processing and analysis. Fractional Fourier transform (FRFT) is generalization to FT and belongs to class of time frequency representations [1-5]. FRFT is linear transform and depends upon an adjustable parameter α. It is called FT to the ath power, where a needs not be an integer. Mathematically ath order FRFT is the ath power of FT operator so FRFT is also called fractional powers of ordinary FT. FRFT is effectively applied in all conditions where ordinary FT is used. FRFT is also called decomposition of the signal in terms of chirps. FRFT has found several applications in the areas of solution of differential equations [6], quantum mechanics [7], signal and image recovery [8], restoration and enhancement [9], space or time-variant filtering, multiplexing [10] and study of time frequency distributions [11-12]. Window functions have also played an important role in digital signal processing and analysis, digital filter design and speech processing [13-14]. These are used in harmonic analysis to reduce the effects of spectral leakage. A window function which gives a spectrum that has minimum leakage is preferred. In signal processing, a window function also known as an apodization function or tapering function is a mathematical function that is zero valued outside of some chosen interval. When a signal or function is multiplied by window function it also becomes zero outside the chosen interval [15]. A complete review of window functions and their properties using discrete FT (DFT) was presented by Harris [16]. Over time, many window functions [17-20], have derived to optimize some features of a new window and for easy implementation. A practical window usually has a trade-off between -20 0 20 0.5
A DUAL LAYERED ENCRYPTION ALGORITHM FOR WIRELESS EQUIVALENT PRIVACY (WEP) ALGORITHM.

Wired Equivalent Privacy (WEP) protocol was adopted to protect authorized users from unauthorized access and eavesdropping in the IEEE 802.11 wireless LANs (WLAN). However, it had been proven that the WEP protocol fails to provide data confidentiality and authentication [2, 14]. The WEP provides encrypted communication using an encryption key between the client station and Access point (AP). All client stations and APs on a network use the same key to encrypt and decrypt data. The key resides on both the client station and the AP [14]. The above rendered the WEP protocol naked to major forms of attack. Thus in this paper a keyed-message authentication code aimed at preventing an intruder from tampering with packets in transit is proposed, with a revised authentication scheme to avoid authentication spoofing and reduce replay attacks. We also employed private IV scheme alongside the use of day and session keys that counters several attacks. The proposed WEP was tested with HTTPNet and TelnetNet with each client having their respective sessions. Finally, simulation methodology is presented, with the simulated results provided. Our studies show that the enhanced model provides better data confidentiality.
2D Color Code Interference Cancellation by Super Imposing Methodology

Today the 2-D barcodes have become more popular for information embedding. To encode information with high spatial density while ensuring robust reading by an optical system is the main goal of a barcode system. To enhance the density of information, different ink colors could be used. A High Capacity Color Barcode framework is proposed by exploiting the spectral diversity afforded by the Cyan, Magenta, Yellow print colorant channels and the complimentary Red, Green and Blue channels, respectively, used for capturing color images. Here a three-fold increase in the data rate is achieved by encoding independent data in the C, M, and Y print colorant channels and decoding the data from the complimentary R, G, and B channels captured via a mobile phone camera. This paper presents a framework of color barcode for mobile phone applications by exploiting the spectral diversity afforded by the cyan (C), magenta (M), and yellow (Y) print colorant channels which is more commonly used for color printing and the complementary in order to red (R), green (G), and blue (B) channels, respectively, used for capturing color images. In this paper the system exploit this spectral diversity to understand three-fold increase in the data rate by encoding independent data in the C, M, and Y print colorant channels and decoding the data from the complementary R, G, and B channels captured via a mobile phone camera. To mitigate the effect of cross-channel interference among the print colorant and capture color channels, the system develops an algorithm for interference cancellation which is based on a physically-motivated mathematical model for the print and capture processes. To collect the model parameters which are necessary for cross-channel interference cancellation, this scheme proposes a super imposing methodology. Experimental result clears that the scheme framework successfully overcomes the impact of the color interference, providing a low bit error rate and a high decoding rate for each of the colorant channels when used with a corresponding error correction scheme.

Panicca: Panic on Cross-Section Averages

The cross-section average (CA) augmentation approach of Pesaran (2007) and Pesaran et al. (2013), and the principal components-based panel analysis of non-stationarity in idiosyncratic and common components (PANIC) of Bai and Ng (2004, 2010) are among the most popular “second-generation” approaches for cross-section correlated panels. One feature of these approaches is that they have different strengths and weaknesses. The purpose of the current paper is to develop PANICCA, a combined approach that exploits the strengths of both CA and PANIC.
Microlens Arrays and Biocompatible Channels

The intent of this chapter is to review the use of sol-gel processing of silica and silica-titania optical coatings in recent research by the authors in three different areas: the synthesis of active gradient-index (GRIN) materials by multilayer deposition of erbiumand ytterbiumdoped silica-titania films, the improvement of the optical and morphological qualities of microlens arrays fabricated by laser ablation and the functionalization of polydimethylsiloxane (PDMS) channel preclinical devices. Through the use of sol-gel, layers with specific properties can be produced. In this regard, undoped and erbiumand ytterbium-doped SiO 2 -TiO 2 films have been produced and characterized using atomic force microscopy (surface topography evaluation) and spectral ellipsometry (determination of optical constants, thickness and porosity of the films). In a second application, a silica sol has been synthesized to coat microlens arrays fabricated by laser ablation. The deposited layer reduces the surface roughness of the microlens array, which yields the improvement of the contrast and the homogeneity of the foci. Finally, PDMS channels fabricated with laser technologies and soft-lithography methods are coated with a sol-gel-derived silica film to avoid the degradation of the material with organic solvents, and their biocompatibility is studied.
The study of particle filter for satellite angular rate estimation without rate sensor measurement

This paper studies particle filter algorithm to estimate the angular rate of a satellite without the rate sensor measurements. In this work, the performance of the algorithm is studied in terms of capability to estimate the angular rate by using the Euler angles attitude information only. The effects of the number of particles on the algorithm performance are also investigated in terms of accuracy and computational aspects. The performance of the particle filter algorithm is verified using real flight data of Malaysian satellite.
Managing measures of feed costs: benchmarking physical and economic feed efficiency.

Problems associated with the measurement and monitoring of physical feed efficiency are reviewed. We propose targets for gross feed efficiency based on milk production and stage of lactation and present elements to diagnose possible causes when actual results depart from the proposed targets. This is followed by the development of a meaningful benchmark of economic feed efficiency based on market prices for milk components, amounts of major nutrients required for the production of these milk components, and market prices of these nutrients derived from market prices of all feeds traded in a given market. The resulting index, the Cow-Jones Index, is used as a proxy to a benchmark of income-over-feed-costs with the clear benefits that: (1) it doesn’t use a specific benchmark diet, (2) it uses market information for both milk components and feeds, and thus, can be regionalized, and (3) it can be easily calculated for different levels of target milk production.
Great Expectations For Tourism And Regional Development In Romania: Why Are Not They Met?

Despite the high potential of the Romanian tourism competitiveness and reducing interregional disparities, the results obtained in the last fifteen-twenty years are far below expectations. This paper aims to identify national and regional characteristics of tourism in Romania during the period 1990 to 2010 and to evaluate the most important factors that influenced foreign tourists' arrivals in Romania and the departures of Romanian tourists abroad. As infrastructure is one of the main obstacles to tourism development we have used data from development regions in order to explore the changes in the concentration of accommodation capacities. We have developed econometric models estimated on panel data to assess the implications of road infrastructure development and accommodation capacity utilization on economic results of tourism. The results indicate the important relationship between the territorial distribution of road infrastructure and the concentration of accommodation capacity.
BONE QUALITY PARAMETERS OF HENS EVALUATED DURING AND AFTER A SECOND MOLT

In the present study, the effects of alternative molting compared to conventional (feed removal) and nonmolted treatments on bone quality parameters of Hy-Line W-36 hens submitted to a second molt at 142 weeks of age were evaluated. Treatments were, conventional molt (10 days fasting followed by cracked corn for 8 days and pullet developer diet for 10 days) and alternative molting treatments: soy hulls based diet (12% CP, 1455 ME kcal/kg, 1.38% Ca) for 14 days followed by cracked corn for 4 days and pullet developer diet for 10 days, the other three molt regimens consisted of feeding soy hulls during 4, 8 or 12 days followed by 10, 6 or 2 days respectively, of soy hulls based diet and 4 days of cracked corn plus 10 days pullet developer diet. Nonmolted (control) hens were fed laying hen diet. At 143, 146 and 175 weeks of age, birds (n=135, 9 replicates/treatment) were euthanized. The left tibia was retrieved for bone ash. Blood were taken on days 10 and 28 of molt, when birds were 143 and 146 weeksold, respectively. Bone serum markers evaluated were total calcium (TCa), ionized calcium (iCa), plasma alkaline phosphatase (ALP) and lactate (L). Controls showed higher values for bone ash (37.12%) versus all molted hens at 175 wks. Treatment effect (P<0.0001) was observed for TCa, with the controls showing higher values (24.10 and 25.41 mg/dL at 143 and 146 weeks, respectively). For iCa, the lowest value (75mMol/L) was observed in birds submitted to the conventional molt.
Experimental Evaluation of Succinct Representations of JSON Documents

Experimental Evaluation of Succinct Representations of JSON Documents Edman Paes dos Anjos School of Computer Science Engineering Collage of Engineering The Graduate School Seoul National University The massive amounts of data processed in modern computational systems is becoming a problem of increasing importance. This data is commonly stored directly or indirectly through the use of data exchange languages, such as JSON (JavaScript Object Notation) and XML (eXtensible Markup Language), for human-readable platform agnostic access. This thesis focuses on exploring succinct representations of JSON documents as a means of achieving reduced RAM usage of files in main memory, and of permitting the compression of data files stored in disk. The representations we propose are mainly based on the idea that JSON documents, as most data exchange formats, can be deconstructed into structure and raw data. In our method we represent the tree-like structure of the document with succinct trees, as opposed to the usual pointer-based implementation. Furthermore, the remaining raw data is reorganized into arrays of attributes and values. Attributes are stripped of redundancies and stored sequentially in a simple contiguous array, while values are represented through a bit string indexed heterogeneous array. This deconstruction between structure and data allows for a straight-
Existence and Exploitability of Financial Analysts' Informational Leadership

This paper bridges two recent studies on the role of analysts to provide new and relevant information to investors. On the one hand, the contribution of analysts to long-term price discovery on the US market is rather low. Considering earnings per share forecasts as the main output of analysts’ reports, their information share amounts to only 4.6% on average. On the other hand, trading strategies set up on these EPS forecasts are quite profitable. Self-financing portfolios yield excess returns of more than 5% over the S&P 100 index for a time period of 36 years, which is persistent after controlling for the well-known risk factors. In this paper, we discuss the link between the low information shares and the high abnormal returns. We argue that information shares of analysts cannot be higher, because otherwise their forecasts would lead to excessively profitable trading strategies which are very unlikely to persist over such a long period of time.
Essays on banking

This dissertation contains three essays which look at the role of price competition in banking. The method of investigation is a theoretical one. The first two essays examine the relative efficiency of relationship banking and price banking. The third essay discusses the determination of bank interest margin. Conventional wisdom suggests that increased interbank competition should improve social welfare and thus price banking should dominate relationship banking. Essay one shows that the opposite result may occur when the product market is imperfect and the lending instruments are loan commitments. Under relationship banking both banks and borrowers have bargaining power. The borrowers have substantial bargaining power when the costs of stwitching banks are small. In this case, it pays the banks to charge interest rates below the competitive rates in order to keep their customers. The interest losses are compensated for by higher commitment fees paid upfront by the borrowers. Since interest costs are lower under relationship banking than under price banking, borrowers produce more and output price declines. Social welfare thus unambiguously increases. Essay two goes on to examine the relative efficiency of relationship banking and price banking under the asset substitution problem. The bank-customer relationship is assumed to provide a credible commitment for a borrower to refrain from transacting with other banks. The outcome under relationship banking is second-best since underinvestment results in solving the asset substitution problem. The multilateral credit transactions permitted by price banking impose negative externalities to existing loans by inducing the borrower to substitute riskier project. More underinvestment is needed to resolve the dual incentive problem and equilibrium results in reduced welfare for borrowers. Essay three tackles the determination of bank interest margins using a simple production-based model of risk-neutral banks which face (i) loan default risk, (ii) interest rate risk, (iii) capital regulation, and (iv) deposit insurance. The optimal bank interest margin is shown to be increasing with the variability of the short-term money market rate, but decreasing with either a stiffer capital requirement or an increase in the flat-rate deposit insurance premium.
