Authors: Silva Marco Antonio Marques da , Silva Evani Zambon Marques da
Published: February 2018

A violência de gênero constitui-se hoje numa das maiores preocupações entre os povos. O Brasil tem buscado garantir o Princípio da Dignidade Humana de modo a efetivar a Tutela dos Direitos Humanos. A Lei Maria da Penha (Lei nº 11.340/2006) dispõe sobre a criação dos Juizados de Violência Doméstica e Familiar contra a mulher e estabelece medidas de assistência e proteção às mulheres em situação de violência doméstica e familiar. Não é sem motivo que a violência doméstica é considerada uma das formas de violação aos direitos humanos. Tanto a violência como a legislação que busca proteger a vítima, devem ser tratadas de modo interdisciplinar, voltando-se para a magnitude do problema, para além da forma punitivas.

Authors: Ladeira Lucas Zanco , Moreno Edward David
Published: February 2018

Smart cards tem a capacidade de armazenar uma ou múltiplas aplicações e as executar quando requisitadas. Essas aplicações podem compreender armazenamento de dados pessoais, até mesmo execução de transações financeiras. No caso de aplicações financeiras, é necessário fazer o uso de autenticação para que se o cartão for roubado ou perdido o mesmo não possa ser utilizado. Sendo assim, a informação autenticadora é de vital importância para barrar utilização não autorizada. Isso torna necessário manter a transmissão da mesma ao smart card segura, fazendo o uso de algoritmos criptográficos. O objetivo do projeto é de utilizar um algoritmo de criptografia homomórfica para tornar sigiloso um PIN durante a transmissão ao cartão.

Authors: Mano Leandro Yukio , Funes Marcio Maestralo , Volpato Tiago , Neto José Rodrigues Torres
Published: February 2018

Atualmente, é crescente o número de pacientes que são tratados em casa, principalmente em países como o Japão, Estados Unidos e da Europa. Além disso, o número de idosos tem aumentado significativamente nos últimos quinze anos, e essas pessoas, muitas vezes, preferem receber tratamento médico em suas residências.  No entanto, podem acontecer situações críticas durante esse período de recuperação, como por exemplo, o paciente idoso sofrer uma queda e agravar o seu quadro clínico. Neste cenário, avanços em Computação Ubíqua e Internet das Coisas (IoT) têm contribuído para evitar essas situações. Em particular, dispositivos embarcados, juntamente com a captura de movimentos por meio de sensores, podem ser aplicados para desenvolver soluções que ofereçam mais segurança para essas pessoas. Todavia, observa-se uma dificuldade de classificar os movimentos de um indivíduo e identificar, de fato, um movimento considerado anormal. Assim, o principal objetivo deste trabalho é a detecção e classificação dos movimentos utilizando dados conjuntos de sensores distintos e dispositivo embarcado. Paradigmas de Inteligência Artificial (AI) foram aplicados para a classificação dos movimentos e os testes realizados na arquitetura SAHHc. Os resultados apontaram uma precisão de 96.62\% na identificação das atividades executadas por um paciente/idoso.

Authors: Parra Carlos M , Tremblay Monica , Castellanos Arturo
Published: February 2018

In this study we develop a simplified technique for helping researchers and analysts visualize the alternative prominence of term eigenvectors obtained after exploring term associations (Term Clusters) while conducting Text Data Mining on a collection to Corporate Social Responsibility (CSR) reports. The collection analyzed is comprised of CSR reports produced by 7 US firms (Citi, Coca-Cola, Exxon-Mobil, General Motors, Intel, McDonald’s and Microsoft) in 2004, 2008 and 2012. The analysis is performed by year in order to discern how the prominence of term eigenvectors has evolved for each firm and for different CSR topics. Results indicate that term eigenvectors maintain their prominence when CSR topics are related to the core business of the firm in question.

Authors: Araujo Aleteia Patricia Favacho , Ferreira Antonio M. A. , C.  Drummond André
Published: February 2018

Cloud computing platforms provide easy and transparent access to a company’s storage infrastructure through services. it allows users to store their data at remote disks and access them anytime from any place. On the other hand, with the deployment of Electronic Document Management (EDM) to manage the insertion, sharing, and retrieval of information assigned to a digital document it is necessary that the processes of searching, indexing and storage of digital documents are carried out efficiently. Besides the use of computational tools focused on archiving digital documents, the storage solution must provide reliability and authenticity on the availability of digital documents. With object storage systems being increasingly accepted as replacements for traditional file or block systems and recognized as a preferred way to expose one’s storage infrastructure, it is important to effectively measure the performance of these services. This paper addresses the deployment project of a content-addressable storage infrastructure in a large company and conducts performance, availability and scalability evaluation to measure the gains in r/w access of the proposed solution in different scenarios proposed.

Cultural differences still matter: Adapting products and positioning for international success
Authors: Au-Yong-Oliveira Manuel , Reis de Sousa Rafael José , Gonçalves Ramiro
Published: February 2018

This article focuses on technology-based companies and the way they perceive the influence of cultural and social differences on their internationalization process. As national cultures and institutions differ from country to country and even more so between different continents, we herein discuss the adaptation of products and services to the cultures and institutions of each environment, for the optimization of sales and product positioning. An in-depth example of a platform that is for sale in different countries, including Portugal and Mozambique, was described. In addition, results from interviews and a questionnaire administered to Portuguese internationalized companies were analyzed. A review of the existing literature was also performed. The strategic notion of positioning is central to organizational success and should differ from context to context, where necessary. Namely, different economic and education conditions lead to distinct behaviors, which have a repercussion on the position to be adopted in order to sell products abroad.
Economic Impacts of land-use Conflicts on Livelihoods. A case study of Pastoralists-farmer Conflicts in the Agogo Traditional Area of Ghana
Authors: Opoku Patrick
Published: February 2018

Pastoralists-farmer conflicts are not new to farming communities in Ghana but in recent years the magnitude of these conflictshave increased in the Agogo traditional area. It is still not clear what impacts these conflicts have on livelihoods and how toensure that the conflicts are reduced in Ghana. This study was undertaken to bridge this knowledge gap. Using a classicalexperimental design, data for the study was obtained from both primary and secondary sources. The data was analyzed usingcontent analysis and inferential statistics; t-test. The study found out that reduction in farm produce, insecurity and increaseloan default rates were among some of the major economic impacts of the conflicts on livelihoods. Interruption of education ofchildren due to low income also featured prominently. For example, the average farm income of farmers in the conflict area (GHC827.00) was significantly lower as compared to farmers in the non-conflict area (GHC 3600). Recommendation for reducing theconflicts includes; zoning areas for grazing and protecting communal grazing rights.
Achieving sustainable fisheries management: A critical look at traditional fisheries management in the marine artisanal fisheries of Ghana, West Africa
Authors: Nunoo F. K. E.
Published: February 2018

Sustaining fishery resources is crucial to the survival and wealth of artisanal fishers in Ghana. The artisanal fisheries sector ofGhana provides food, employment, livelihood support and socio-economic benefits to the Ghanaian economy. Fishery resourcesof Ghana are under stress from population pressure, increasing demand of fish and fishery products and open-access regime.Formal fisheries management practices have not yielded the desired results. There is an increasing need for traditional fisheriespractices to be incorporated into formal fisheries management practices. The aim of this paper is to conduct an in-depth studyon traditional marine fisheries management systems in Ghana in order to provide information to enhance the management of theartisanal fisheries.Data was collected through document analysis (between May 2014 and January 2015), field observation andquestionnaire-based interview (between 26th and 30th of July 2014). Results show that the Chief Fisherman and CommunityBased Fisheries Management Committee are important structures in the fisheries management system of Ghana. The ChiefFisherman is the person that leads resolution of disputes and gives access to fishing in the communities. There are a number ofmeasures such as non-fishing days, ban on landing certain fish species during festival periods to prevent overfishing. Taboos andcultural practices such as performing of rituals to ‘sea gods’ and consulting of oracles during certain periods of the year help tomanage the fish stocks. With respect to the performance of the fishing communities, Elmina performed better with combinationof various traditional practices to prevent overfishing. Fishers in Elmina also had adequate knowledge of current fishing rulesand regulations than fishers in Adina, Chorkor and Dixcove. Fishers and fishing communities must be educated on the need toavoid unapproved fishing practices to help keep the fishery resources healthy for sustainable exploitation. Fishers should also beequipped with alternative livelihood jobs in order to reduce the pressure on the fishery resources. A national policy to integratetraditional management practices into formal fisheries management plans should be established.
The philosophy of biometry as a basic tool for the improvement of global biological research
Authors: Tzortzios Stergios
Published: February 2018

It is well known the meaning and importance of the biometry in the entire flow of any biological and environmental research-from the first experimental design, to the data collection and their organization, the data manipulation and their analysis, up tothe results interpretation and their presentation. It is also well known the “stataphobia” (the fear of statistics) that exists in theresearchers -especially the young ones- in their efforts to carry on serious research. Certain surveys on the publications done uptoday in many countries revealed the remarkable gap that exists between the research work published by the researchers of thedeveloped countries and those of the developing and much more the underdeveloped ones. In this study a review of the today’sstatus of the biological research in all the countries is undertaken in order to present the possible reasons of the existing gap,hoping to reveal the proper solutions for the desirable improvement. Relevant references have been presented by experiencedscientists in many biological-biometrical conferences, organized in the developing countries, noting the serious need of helpfor the improvement in the effectiveness of their biological research. The recent remarkable development of new technologiessciences-Information, Communication and Technology (ICT) offer the capacity required to this purpose. An interesting effort hasalready started by a forum of scientists from many countries by organizing a complete site in the internet on a platform basedon the Library of Alexandria, called Research Methodologies of the Library of Alexandria (RMLA), offering many lectures onspecial research matters and the availability for accepting certain questions on research matters. The International BiometricSociety-IBS- is the appropriate scientific society that could act based on the line of its bylaws in order to help the researcheffectiveness in the developing countries aiming to the improvement of the global biological research
Impact of Eidolon helvum on roost trees on UENR campus
Authors: Danquah E.
Published: February 2018

Four sample plots, each of size 20m by 20m were systematically distributed in two strata (i.e. two plots in bat-occupied zone andthe remaining two plots in bat-unoccupied zone, to serve as control units). Using six (20m × 20m) sample plots each, basal area,canopy, and heights of trees with DBH 1m were measured. Fourteen individual trees were recorded in the bat-unoccupied zone,resulting in only seven tree species. On the other hand, 16 tree species, corresponding to a total of 25 trees were recorded in thebat occupied zone. Albizia zygia, Antiaris toxicaria, Azadiractha indicia, Holarrhena floribunda, Morinda lucinda, and Sterculiatragacantha were common to both zones. The Shannon Wiener species diversity index was found to be higher (H1=1.92) in batoccupied zones and lower (H1=1.45) in bat-unoccupied zone. Estimates of tree basal area and tree height were much higherin bat occupied zones compared to bat-unoccupied zones. (Mann-Whitney U test: U = 573.0, p < 0.05), tree basal area (U= 674.0, p < 0.05), tree height (U = 632.0, p < 0.05) and tree canopy cover (U = 329.0, p < 0.05). Holarrhena floribunda(0.34 m2/h) and Ceiba pentandra (0.22m2/ha) contributed the largest basal area (32.94% of the total basal area) whilst Sennasiamea (0.01m2/ha) and Tectona grandis (0.01m2/ha) yielded the smallest basal area (1.17%). In general, bats seem to greatlypatronize areas with higher densities of tall trees than relatively open areas with shorter trees.

Authors: Medeiros Giovanna Lemos
Published: February 2018

A presença das mulheres no campo é uma realidade no Brasil, as triplas jornadas de trabalho que elas realizam, não são reconhecidas. Isso porque, o sistema capitalista em que estamos inseridas, é patriarcal, onde os homens mantêm o poder primário e as lideranças políticas. O fato dessas mulheres residirem em áreas rurais, não as exclui ou diminuem as possibilidades de viverem dia a dia com a opressão. Neste contexto, a pesquisa teve como tema a caracterização política e socioeconômica das mulheres feirantes, da região do Baixo Munim – Maranhão. O objetivo geral foi caracterizar o nível de organicidade na política e o reconhecimento do trabalho das mulheres da feira agroecológica e solidária do circuito de feiras agroecológicas do Baixo Munim.

O estudo apontou que o circuito de feiras é importante para a vida das feirantes, pois além da renda extra, há a satisfação, o aprendizado e a construção de novos valores nessas mulheres, além do papel das feira agroecológicas, levando uma alimentação limpa de veneno para a mesa da(o) consumidora(or).
Global Measures of Data Utility for Microdata Masked for Disclosure Limitation
Authors: Woo Mi-Ja , Reiter Jerome P. , Oganian Anna , Karr Alan F.
Published: February 2018

When releasing microdata to the public, data disseminators typically alter the original data to protect the confidentiality of database subjects' identities and sensitive attributes. However, such alteration negatively impacts the utility (quality) of the released data. In this paper, we present quantitative measures of data utility for masked microdata, with the aim of improving disseminators' evaluations of competing masking strategies. The measures, which are global in that they reflect similarities between the entire distributions of the original and released data, utilize empirical distribution estimation, cluster analysis, and propensity scores. We evaluate the measures using both simulated and genuine data. The results suggest that measures based on propensity score methods are the most promising for general use.
The Relevance or Irrelevance of Weights for Confidentiality and Statistical Analyses
Authors: Fienberg Stephen E.
Published: February 2018

Sample survey weights represent a standard part of the survey statistician's repertoire, but they remain a mystery for many of those who work with survey data. They also pose a potential challenge for confidentiality protection. Much has been written about how to use weights in statistical analyses since the basic idea of weighted estimates|weighting units inversely proportional to their probability of selection|emerged from the classic paper by Horvitz and Thompson. Very little has been written about the effect of releasing survey weights on the confidentiality of survey data. The two topics are inextricably intertwined. This paper discusses both, largely from the model-based perspective, and explains what is claimed and/or known about the issue of confidentiality protection. The paper also provides a prescription for ways to deal with weights both for analysis and for disclosure limitation.
Partial Information Releases for Confidential Contingency Table Entries: Present and Future Research Efforts
Authors: Slavkovic Aleksandra B.
Published: February 2018

Tabular data have been a staple product for disseminating information derived from the confidential microdata that fuel social science research and inform policy decisions. This paper outlines recent results on disclosure risk assessment associated with the release of high-dimensional contingency tables, and discusses some related research problems. The main focus is the partial information release strategy, through which agencies can release relevant marginal and conditional tables along with the sample size instead of a full contingency table. The most recent approaches in this area combine statistical and operations research methodologies with tools from computational algebra.

This issue of the Journal of Privacy and Confidentiality focuses on four technical contributions, three of which deal with different aspects of efforts to produce “sanitized” synthetic statistical databases or sanitized responses to queries. The first two of these papers focus on the utility of sanitized databases based on the technique of multiple imputation, the third deals with intruder-styled attacks on output perturbation sanitizers. The fourth addresses a different problem regarding access to, and the use of, web-based data via anonymous authentication.
How Can We Analyze Differentially-Private Synthetic Datasets?
Authors: Charest Anne-Sophie
Published: February 2018

Synthetic datasets generated within the multiple imputation framework are now commonly used by statistical agencies to protect the confidentiality of their respondents. More recently, researchers have also proposed techniques to generate synthetic datasets which offer the formal guarantee of differential privacy. While combining rules were derived for the first type of synthetic datasets, little has been said on the analysis of differentially-private synthetic datasets generated with multiple imputations. In this paper, we show that we can not use the usual combining rules to analyze synthetic datasets which have been generated to achieve differential privacy. We consider specifically the case of generating synthetic count data with the beta-binomial synthetizer, and illustrate our discussion with simulation results. We also propose as a simple alternative a Bayesian model which models explicitly the mechanism for synthetic data generation.
An Analysis of Google Logs Retention Policies
Authors: Toubiana Vincent , Nissenbaum Helen
Published: February 2018

To preserve search log data utility, Google groups search queries in log bundles by deleting the last octet of logged IP address. Because these bundles still contain identifying information, part of these search logs can be de-anonymized [Jones et al., 2008]. Without an external audit of these search logs, it is currently impossible to evaluate their robustness against de-anonymizing attacks. In this paper, we leverage log retention policy ambiguities to show that quasi-identifiers could be stored in sanitized search query logs and could help to de-anonymize user searches. This paper refers to Google Search and Google Suggest log retention policies and shows that even with the highest degree of anonymization that Google offers, one could separate user queries with a high granularity. Because Google Suggest is queried every time a user types a character in the Google Chrome navigation box, the privacy of Chrome users could be compromised with respect to their browsing histories. Such ambiguities within log retention policies are critical and should be addressed, as anonymized logs could be shared with third parties without prior user consent.

How Uncertainty about Privacy and Confidentiality is Hampering Efforts to More Effectively Use Administrative Records in Producing U.S. National Statistics
Authors: Gates Gerald W.
Published: February 2018

U.S. federal statistical agencies continually face challenges in obtaining and using administrative records and in providing useful analytic products to support policy analysis and program planning. At each of three decision points—obtaining the administrative data, integrating the data into statistical programs, and releasing useful data products—concerns over privacy and confidentiality determine to a great extent how effectively these data are used. Although there is a long history of relevant research on privacy attitudes and methodologies to protect conconfidentiality in published data, agency decisions to share or publish data are not necessarily informed by known risks. Additional research is proposed to help identify and manage these risks. The paper also proposes government actions to ensure that U.S. federal statistical agencies are meeting the nation's data needs through the appropriate application of survey and administrative data.
Privacy Protection from Sampling and Perturbation in Survey Microdata
Authors: Shlomo Natalie , Skinner Chris J.
Published: February 2018

Statistical agencies release microdata from social surveys as public-use files after applying statistical disclosure limitation (SDL) techniques. Disclosure risk is typically assessed in terms of identification risk, where it is supposed that small counts on cross-classified identifying key variables, i.e. a key, could be used to make an identification and confidential information may be learnt. In this paper we explore the application of definitions of privacy from the computer science literature to the same problem, with a focus on sampling and a form of perturbation which can be represented as misclassification. We consider two privacy definitions: differential privacy and probabilistic differential privacy. Chaudhuri and Mishra (2006) have shown that sampling does not guarantee differential privacy, but that, under certain conditions, it may ensure probabilistic differential privacy. We discuss these definitions and conditions in the context of survey microdata. We then extend this discussion to the case of perturbation. We show that differential privacy can be ensured if and only if the perturbation employs a misclassification matrix with no zero entries. We also show that probabilistic differential privacy is a viable alternative to differential privacy when there are zeros in the misclassification matrix. We discuss some common examples of SDL methods where in some cases zeros may be prevalent in the misclassification matrix.

The study was undertaken to find out the profitability and export potentialities of pumpkin cultivation in the char lands of Rangpur and Gaibandha district of Bangladesh. A total of 120 pumpkin growers taking 60 farmers from each district were randomly selected for the study. Descriptive statistics was used to analyze cost and return of pumpkin. The Cobb-Douglass production function was used to estimate the coefficients of the various variables analysed and MPP, MVP and resource use efficiency were also used to estimate the efficiency of resource use in the study area. The study revealed that net returns were positive for pumpkin cultivation. However, the higher net return was estimated for Rangpur district (Tk 105,299/ha) compared to Gaibandha (Tk.93, 936/ha). Bangladesh had comparative advantage for producing pumpkin as the estimates of domestic resource cost (DRC) was less than one. The value of DRC for pumpkin was less than unity implied that the production of pumpkin would be highly efficient for export promotion. The estimated results of the Cobb-Douglass production function showed increasing returns to scale. The results of the efficiency computation indicated that inputs were underutilized. Farmers in the study area used too little input to cultivate pumpkin that means the cost of using inputs is less than the value of marginal product. This suggests that farmers can incur more cost for these inputs to be efficient and then production will be increased.Bangladesh J. Agril. Res. 42(4): 647-663, December 2017

Published: February 2018

The experiment was conducted to know the chemical and cooking properties of nineteen BRRI released high yielding rice varieties (HYVs) including salinity, drought and submergence tolerant varieties. All the rice varities were grown in normal condition. Among the HYVs, amylose content of the varieties range from 19 to 27.0% and BRRI dhan47 contained the highest amylose content (27%). The highest amount of protein (9.3%) was found in BRRI dhan56 followed by BRRI dhan42 (9%) and BRRI dhan43 (8.8%). Alkali spreading value ranged from 3.0 to 7.0. Maximum cooking time (20.5 min.) was required in the variety of BRRI dhan40. Alkali spreading value was found significantly and negatively correlated with cooking time. The kernel elongation ratio was greater than 1.1 in all the varieties except BRRI dhan62. The imbibition ratio was greater than 3.0 in all the varieties except BRRI dhan43 and BRRI dhan61. There were no significant differences between non-abiotic and abiotic stress tolerant varities in respect of chemical and cooking properties because all varities were grown in normal condition.Bangladesh J.

Although Ginger is the main cash crop for small farmers across the country, the economic condition is not satisfactory which can be attributed to high cost of product and low productivity. The study was conducted in four ginger growing areas of Palpa, Nepal in 2012, focusing on cost factors of various inputs. The study revealed that ginger production was profitable on cash cost basis (BCR 7.22). Seed have major cost share for ginger production (65.1%). The estimated coefficients of Cobb-Douglas production function showed that seed, labor and number of years for crop rotation were the significant factors for ginger production. The study concluded that ginger production can be made viable enterprise with increased focus on source seed production and distribution.Bangladesh J. Agril. Res. 42(4): 681-691, December 2017
Intercropping of banana with potato and vegetables

An intercrop-based experiment was conducted for two consecutive years during September 2012 to October 2014 at farmer’s field of MLT site, Shibganj, Bogra to find out the performance of banana intercropped with potato and vegetables. There were three intercrop-based treatments i.e. Banana + Potato, Banana + Radish + Potato and Banana + Cauliflower + Potato were tested along with Sole Banana. The results revealed that all the intercrops produced higher banana equivalent yield over the sole banana in both the years. However, among the intercrop combinations, Banana + Cauliflower + Potato provided the highest equivalent yield (104.04 tha-1 in 2012-13 and 122.50 tha-1 in 2013-14) followed by Banana + Radish + potato. Sole banana produced the lowest equivalent yield in both the cropping seasons. Higher gross margin was also obtained from the intercrop combinations. Among the intercrops, Banana + cauliflower + Potato provided higher gross margin (Tk.656898 ha-1) but due to higher cost, this treatment failed to show higher BCR than Banana + Radish + Potato.Bangladesh J.

Spherical ultrasonic motors (SUSMs) that can operate with multiple degrees of freedom (MDOF) using only a single stator have high holding torque and high torque at low speed, which makes reduction gearing unnecessary. The simple structure of MDOF-SUSMs makes them useful as compact actuators, but their development is still insufficient for applications such as joints of humanoid robots and other systems that require MDOF and high torque. To increase the torque of a sandwich-type MDOF-SUSM, we have not only made the vibrating stator and spherical rotor larger but also improved the structure using three design concepts: (1) increasing the strength of all three vibration modes using multilayered piezoelectric actuators (MPAs) embedded in the stator, (2) enhancing the rigidity of the friction driving portion of the stator for transmitting more vibration force to the friction-driven rotor surface, and (3) making the support mechanism more stable. An MDOF-SUSM prototype was tested, and the maximum torques of rotation around the X(Y)-axis and Z-axis were measured as 1.48 N∙m and 2.05 N∙m, respectively. Moreover, the values for torque per unit weight of the stator were obtained as 0.87 N∙m/kg for the X(Y)-axis and 1.20 N∙m/kg for the Z-axis. These are larger than values reported for any other sandwich-type MDOF-SUSM of which we are aware. Hence, the new design concepts were shown to be effective for increasing torque. In addition, we measured the transient response and calculated the load characteristics of rotation around the rotor’s three orthogonal axes.
Predicting Non-Linear Flow Phenomena through Different Characteristics-Based Schemes
Authors: Teschner Tom-Robin , Könözsy László , Jenkins Karl
Published: February 2018

The present work investigates the bifurcation properties of the Navier–Stokes equations using characteristics-based schemes and Riemann solvers to test their suitability to predict non-linear flow phenomena encountered in aerospace applications. We make use of a single- and multi-directional characteristics-based scheme and Rusanov’s Riemann solver to treat the convective term through a Godunov-type method. We use the Artificial Compressibility (AC) method and a unified Fractional-Step, Artificial Compressibility with Pressure-Projection (FSAC-PP) method for all considered schemes in a channel with a sudden expansion which provides highly non-linear flow features at low Reynolds numbers that produces a non-symmetrical flow field. Using the AC method, our results show that the multi-directional characteristics-based scheme is capable of predicting these phenomena while the single-directional counterpart does not predict the correct flow field. Both schemes and also Riemann solver approaches produce accurate results when the FSAC-PP method is used, showing that the incompressible method plays a dominant role in determining the behaviour of the flow. This also means that it is not just the numerical interpolation scheme which is responsible for the overall accuracy. Furthermore, we show that the FSAC-PP method provides faster convergence and higher level of accuracy, making it a prime candidate for aerospace applications.
