A Multiplicative Seasonal ARIMA/GARCH Model in EVN Traffic Prediction

This paper highlights the statistical procedure used in developing models that have the ability of capturing and forecasting the traffic of mobile communication network operating in Vietnam. To build such models, we follow Box-Jenkins method to construct a multiplicative seasonal ARIMA model to represent the mean component using the past values of traffic, then incorporate a GARCH model to represent its volatility. The traffic is collected from EVN Telecom mobile communication network. Diagnostic tests and examination of forecast accuracy measures indicate that the multiplicative seasonal ARIMA/GARCH model, i.e. ARIMA (1, 0, 1) × (0, 1, 1)24/GARCH (1, 1) shows a good estimation when dealing with volatility clustering in the data series. This model can be considered to be a flexible model to capture well the characteristics of EVN traffic series and give reasonable forecasting results. Moreover, in such situations that the volatility is not necessary to be taken into account, i.e. short-term prediction, the multiplicative seasonal ARIMA/GARCH model still acts well with the GARCH parameters adjusted to GARCH (0, 0).
CaRA : Congestion-aware Routing Algorithm for Data Center Network

The data center networks (DCN) leverage redundant physical links to overcome the bottleneck of traditional tree topology and achieve high bisection bandwidth and goodput for cloud computing platform, so how to use these redundancy links efficiently becomes the key factor for routing designer. This paper analyzes the large flow collision in modular data center network and propose simple experiments to validate the performance decreasing in the aggregated throughput. And then, a recursive congestion-aware routing algorithm (called CaRA) is proposed for decreasing flow collision. We simulate the CaRA with NS-2 simulator, and the results show that CaRA can improve one-to-one packet forward throughput and all-to-all throughput most time. The peak throughput values in these two situations are 50% and 20% respectively.
Evaluation of magnetic flux leakage signals on fatigue crack growth of mild steel

In engineering applications, analysis of crack growth life is useful in situations where an unexpected crack has been found in a component of a machine, vehicle, or structure. The objective of this research is to investigate the correlation curve of magnetic flux leakage, Hp(y) signals by evaluating their critical value point with respect to step size. Moreover, the relation of fatigue crack growth rate, da/dN toward the stress intensity range, ΔK and Hp(y) in metal components is also discussed in this paper. The tension-tension fatigue test was conducted with the metal magnetic memory scanning device and crack opening displacement (COD) gauges in 10 Hz (testing frequency) by applying a load for 3.0-5.0 kN respectively. As a result, the correlation curve of Hp(y) was built with the R-Squared values in the range of 0.99 and one mathematical model has been developed for estimation analysis. The sigmoidal shape curve was plotted on the graph of da/dN versus ΔK and also with Hp(y). Thus, for validation, the linear relation is represented between ΔK and Hp(y) that present a good approach for magnetic parameter to be developed in the fatigue crack growth analysis. Therefore, the magnetic method has greater capability to analyze the fatigue crack propagation life in a real application.

Testing the validity of responses to contingent valuation questioning

One way of assessing the validity of results generated through the application of the Contingent Valuation Method (CVM) is through the analysis of response sensitivity to factors expected to have an influence. Scope testing involves presenting at least two alternative impact scenarios to population sub‐samples and testing for differences between the estimates generated. Most applications of the CVM in Australia have not involved scope testing and those that have yielded mixed results. These studies are reviewed. The results of scope sensitivity and other validity tests are presented for a study aimed at estimating the value of environmental damage caused by dryland salinity in the Upper South East of South Australia.
Do Shareholder Rights Affect the Cost of Bank Loans?

Using a large sample of bank loans issued to U.S. firms between 1990 and 2004, we find that lower takeover defenses (as proxied by the lower G-index of Gompers, Ishii, and Metrick 2003) significantly increase the cost of loans for a firm. Firms with lowest takeover defense (democracy) pay a 25% higher spread on their bank loans as compared with firms with the highest takeover defense (dictatorship), after controlling for various firm and loan characteristics. Further investigations indicate that banks charge a higher loan spread to firms with higher takeover vulnerability mainly because of their concern about a substantial increase in financial risk after the takeover. Our results have important implications for understanding the link between a firm's governance structure and its cost of capital. Our study suggests that firms that rely too much on corporate control market as a governance device are punished by costlier bank loans. The Author 2008.

Monitoring Secchi depth of the Yellow Sea and the East China Sea using a semi-analytical algorithm

Secchi depth, an important optical characteristic of water, is a useful index of water quality and is widely used in many environmental studies. The Yellow Sea and the East China Sea are typical case 2 waters, where concentrations of suspended matter, phytoplankton pigments, and colored dissolved organic matter are higher than those in other open oceans. Two cruises were conducted to investigate the water optical characteristics in the Yellow Sea and the East China Sea in May and June, 2009. 62 water sampling stations of Secchi disk depth were measured in situ in day time, and their values were in the range of 0.0112 to 15.6 m with the mean of 6.72 m and a standard deviation of 3.18 m. In this paper, we adapted a quasi-analytical algorithm to estimate the Secchi depth from satellite ocean data in both coastal and oceanic waters. The development of the algorithm is based on the use of in situ measurements and 8-day MODIS-Aqua remote sensing reflectance data with 4 km spatial resolution. More than 39 matchups were compiled for the MODIS sensor by spatial-temporal matching. The comparison between water transparency retrievals from remote sensing data and in situ measurements yields showed that the determination coefficient was 0.60 and a root mean square error of 8.4 m. This study suggests that the quasi-analytical algorithm provide a promising result on in situ data. In the future, maps of ocean transparency for this area will be derived using this algorithm.
Results and Discussions : 4 . 1 Brand Recall : 4 . 1

When the song ‘Pass the Courvoisier’ remained in Billboard’s hot 100 music Chart for around 20 weeks in addition to significant exposures on TV and radio networks. To the surprise of marketers and advertizing practitioners was meanwhile a double digit in the sales of ‘Courvoisier cognac’ the basic theme of this song. Many more such examples appeared on the marketing communication horizon indicating that such practices may lead to a more effective brand communication relative to conventional advertizing. Following an experimental design, the focus of this research was to analyze and understand the role of brand placement on consumer recognition and recall (salience) of that particular brand. Consistent with the previous literature we found significant brand salience related implications of brand placement in Pakistani context. The findings however also suggest for careful management of the placement strategies. Our findings provide new academic insights into and a foundation for researchers in this regard.
The g-irradiation-induced chemical change from b-FeOOH to Fe 3 O 4

The reactions of g-irradiation on 5 nm b-FeOOH in the presence of isopropanol and water have been investigated. In the initial stage of the g-irradiation, b-FeOOH turned into a-FeOOH. With the g-irradiation continued, a-FeOOH was slowly reduced to Fe3O4. After the g-irradiation with a dose of 64.3 kGy, all the bFeOOH and a-FeOOH disappeared and the product was a single phase of Fe3O4, which had an average particle size of 54 nm. The process of this reaction is discussed. The g-irradiation of b-FeOOH should be a new method of preparing magnetite. # 1999 Published by Elsevier Science Ltd. All rights reserved.
Words Matter: Discourse and Numeracy

Here I discuss elements of critical discourse analysis (CDA) and their importance in relation to quantitative literacy (QL). Through an overview of theory, synthesis of research, and examples, I argue that the discursive nature of textbooks has a nontrivial impact on students' mathematical dispositions an important component of QL. In particular, texts are a means of disseminating the culture of mathematics, one which has a tendency to paint mathematics as esoteric and male-dominated. Such a characterization has profound implications for the numeracy community, one of which is that we cannot assume that changes in curriculum are sufficient for effecting QL -simply transitioning to more contextualized mathematics is not enough. Furthermore, it is critical that we examine our own discourse--whether spoken or through text--for ways in which we may be implicitly or explicitly prolong a view of mathematics in which students have little agency.
Determinants of Capital Structure: Evidence from Tunisian Listed Firms

This paper investigates the determinants of capital structure based on a panel of 32 non-financial companies listed on the Tunisian Stock Exchange over the period 2005-2010. The study is made with reference to different theories of capital structure, namely the trade-off, pecking order and market timing theories with focusing on the impact of market imperfections on debt ratio. Both static and dynamic panel data regressions are performed. The empirical results reveal that firm-specific factors such as firm size and profitability influence capital structure choice in Tunisia, while no meaningful effect is detected for growth opportunities. Our results also show that Tunisian listed companies adjust towards a target debt ratio. The adjustment appears to be slow on the Tunisian market because of high adjustment costs.
Sonifying drawings: characterization of perceptual attributes of sounds produced by human gestures

Friction sounds produced by the pencil of a person who is drawing on a paper are audible and could bring information about his/her gestures. This study firstly focuses on the perceptual significance of the morphology of such sounds, and to what extent gestures could be retrieved by sounds. Sounds recorded during drawing sessions were used in association tests where subjects had to univocally associate friction sounds with different shapes. Results showed that subjects were able to associate sounds with correct shapes and that the auditory characterization of the shape depended on the velocity profile. \\ A sonification strategy was then proposed for human drawings using a friction sound synthesis model. Inspired by the work of Viviani et al. (1982) who exhibited a 2/3-power law relation between kinetics and shape curvature for visual perception, experiments were carried out with the synthesis model, where subjects were asked to adjust the power law exponent so that the most realistic sound was obtained. Results revealed an exponent close to 2/3 as previously found in vision and thus highlighted a similar power law in the auditory modality, providing an ecological way to determine velocity profiles from static shapes and to generate sounds coherent with human gestures.
Euler Equations and Durable Goods

This paper deals with the estimation of the Euler Equation when durable consumption is taken into account. If durables are not separable in utility from non-durables, estimating the Euler Equation without conditioning on them leads to incorrect inference. I use microdata on non-durable and durable consumption from a US rotating panel, the Consumer Expenditure Survey (CEX). I concentrate on cars (new and used). Apart from housing, they represent the largest share of durable expenditure in the sample. I find an estimate of the intertemporal rate of substitution which is higher than in the case where durable goods are not conditioned on, while the evidence on the excess sensitivity is more mixed.
Customer's Purchase Intention of Counterfeit Mobile Phones in Pakistan

Purchase intention is the willingness of people to buy a certain product. When we evaluate the alternatives, purchase decision is ready to be made by the consumer. Purchase Intention does not result in actual purchase every time . The marketing organization should help consumer to act purchase intention. Variety of ways is used by organization to attain it. Our Purpose of this study is basically to identify the purchase intentions of counterfeit mobile phones by consumers in Pakistan. Four preceding factors influence the consumer’s purchase intentions based counterfeits products. By using self-administered questionnaires we collected data from our 160 respondents. For regression analysis we entered all that data into SPSS and do analysis also. Results of our study show significant relationship of past experience and attitude towards counterfeits on purchase intention. The results show insignificant relationship of low price and easy access on purchase intention, and easy access also shows significant relationship towards attitude towards counterfeits. These factors influence the purchase intention. Our this study is a vital source for the national and international marketers to collect information how different factors effect consumer’s purchase intention.
Survey and Screening of Fungicide for the Control of Tomato Black Leaf Mold Pseudocercospora fuligena

Tomato black leaf molds were collected from the six metropolitan cities, which were occurred mainly from the end of August until November. There was no significant difference on the fungal growth between potato dextrose agar and tomato-oatmeal agar media. The mycelial growth of the fungus was robust at a relatively high temperature, from 28 to 30 ° C. The suppression rates of hyphal growth ranged from 17 - 98% on the media supplemented with four different chemicals such as difenoconazole, fluquinconazole and prochloraz manganese complex, metconazole, and flutianil and there is no different suppression rates of the fungicides on the tested Pseudocercospora
Aerosol effect on climate extremes in Europe under different future scenarios

This study investigates changes in extreme temperature and precipitation events under different future scenarios of anthropogenic aerosol emissions (i.e., SO2 and black and organic carbon) simulated with an aerosol‐climate model (ECHAM5‐HAM) with focus on Europe. The simulations include a maximum feasible aerosol reduction (MFR) scenario and a current legislation emission (CLEmod) scenario where Europe implements the MFR scenario, but the rest of the world follows the current legislation scenario and a greenhouse gas scenario. The strongest changes relative to the year 2000 are projected for the MFR scenario, in which the global aerosol reduction greatly enforces the general warming effect due to greenhouse gases and results in significant increases of temperature and precipitation extremes in Europe. Regional warming effects can also be identified from aerosol reductions under the CLEmodscenario. This becomes most obvious in the increase of the hottest summer daytime temperatures in Northern Europe.
Possible forms of seismic anisotropy of the uppermost mantle under oceans

The apparent body wave velocities υP of the oceanic mantle immediately below the Mohorovicic discontinuity (M), obtained from oceanic refraction shooting, can depend on azimuth ϕ; because of real mantle anisotropy or horizontal variations in an isotropic crust and mantle. A small anisotropy of the uppermost mantle leads to υP(ϕ)=∑n=04An cosn ϕ sin4-n ϕ=∑n=−22Bneinϕ The An determine 5 of the 21 elastic parameters of the uppermost mantle. Curvature in the M discontinuity has the same effect on velocities υP(ϕ), but the azimuth dependence found by Hess in Raitt's and Shor's velocities, if real, is too large to be due to curvature. A sloping M discontinuity adds to velocities υP(ϕ) a term a cos ϕ + b sin ϕ. In a refraction survey of anisotropy, only two lines need be reversed to find a and b. If the ϕ dependence of velocities υP is due to a small mantle anisotropy and a small slope of the M discontinuity, velocities υP(ϕ) is determined for all ϕ by shooting five different lines through a point and reversing two of them or simply by shooting seven different lines. The theory is compared with Raitt's and Shor's data as reported by Hess.
Recognition of filled walnuts and empty walnuts using acoustic signal processing.

An intelligent walnut recognition system combining acoustic emissions analysis, decision tree and fuzzy inference system (FIS) was developed and tested. In data acquisition part, Fast Fourier Transform (FFT) of impact signals was measured. Feature was extracted in two ways: using time domain and FFT of impact signal. The 66% of samples were used for training and the remains were used for testing. In selection feature part, the most important feature selected was: average and the second frequency amplitude of FFT. The method is based on the feature generation by FFT and time domain, produce decision tree with J48 algorithm and classification by fuzzy rules. The output of J48 algorithm was employed to produce the crisp if-then rule and membership function (MF) sets. The structure of FIS classifier was then defined based on the crisp sets. The results showed that the total classification accuracy was 94.7%, and the proposed FFT-J48-FIS model can be used in separation of filled walnuts from empty walnuts.

Conservative and Novel Treatment Options for Fecal Incontinence

Fecal incontinence (FI) in adults is a troublesome condition that effects substantial portion of the population and represent a major social and economic burden. The first line of treatment involves conservative therapy and physical treatments. When these measures fail, other interventions are warranted. In the last few years, new emerging techniques for the treatment of FI have become available, including sacral neuromodulation, posterior tibial stimulation, acupuncture, internal anal sphincter augmentation, temperature controlled radiofrequency anal energy delivery and stem cell transplantation. This paper discusses the conservative and novel treatment options for FI.
The Effect of Radiogenic Heating on the Amino Acid Content of an Early Cometary Body

This study compares the rates for the formation and destruction of amino acids in the liquid cometary core subjected to radiogenic heating by the β+ decay of the cosmogenic nuclide 26Al. The evolution of the temperature and mass of the comet were computed along with the dynamics of relatively complex organic species such as amino acids. Given the experimentally determined rate coefficient for the radiolysis of amino acids in water solution, the destruction of amino acids is virtually completed after an absorbed radiation dose of ~1 kGy. The calculations suggest that the liquid water core in comets with an initial radionuclide abundance that is sufficient to crystallize and melt the original amorphous ice is subjected to a dose of 100 - 1500 kGy. Any amino acid concentration formed in water either by radiolysis of simpler compounds or by thermal processes such as the synthesis of Strecker could not survive the irradiation delivered by the decay of 26Al.
