Surface Profiling and Core Evaluation of Aluminum Honeycomb Sandwich Aircraft Panels Using Multi-Frequency Eddy Current Testing
Authors: Reyno Tyler , Underhill P. Ross , Krause Thomas W. , Marsden Catharine , Wowk Diane
Published: August 2017

Surface damage on honeycomb aircraft panels is often measured manually, and is therefore subject to variation based on inspection personnel. Eddy current testing (ECT) is sensitive to variations in probe-to-specimen spacing, or lift-off, and is thus promising for high resolution profiling of surface damage on aluminum panels. Lower frequency testing also allows inspection through the face sheet, an advantage over optical 3D scanning methods. This paper presents results from the ECT inspection of surface damage on an approximately flat aluminum honeycomb aircraft panel, and compares the measurements to those taken using optical 3D scanning technology. An ECT C-Scan of the dented panel surface was obtained by attaching the probe to a robotic scanning apparatus. Data was taken simultaneously at four frequencies of 25, 100, 400 and 1,600 kHz. A reference surface was then defined that approximated the original, undamaged panel surface, which also compensated for the effects of specimen tilt and thermal drift within the ECT instrument. Data was converted to lift-off using height calibration curves developed for each probe frequency. A damage region of 22,550 mm2 area with dents ranging in depth from 0.13-1.01 mm was analyzed. The method was accurate at 1,600 kHz to within 0.05 mm (2s) when compared with 231 measurements taken via optical 3D scanning. Testing at 25 kHz revealed a 3.2 mm cell size within the honeycomb core, which was confirmed via destructive evaluation. As a result, ECT demonstrates potential for implementation as a method for rapid in-field aircraft panel surface damage assessment.
Investigation into University Students Restoration Experience: The Effects of Perceived Sensory Dimension and Perceived Restorativeness
Authors: Malekinezhad Fahimeh , Bin Lamit Hasanuddin
Published: August 2017

Salutogenic landscape with its health-promoting qualities is a solution for ever-increasing problem of stress for university students as a vulnerable group. Based on nature related theories, natural environments could have a salutary effect on psychological restoration through stress alleviation. There is a body of research on investigating the impact of open green space characteristics for increasing of psychological restoration through framework of attention restoration theory and supportive environment theory. However, there is little knowledge on how the interaction among these characteristics could promote perceived restoration experience (PRE). To address this problem, using perceived sensory dimension (PSD) for open green space qualities and Perceived Restorativeness (PR) as properties of restorative environments, this study assessed the extent to which the PSD and PR impact on PRE. Using 444 screened data, the mediation effect of PR on the association of PSD to PRE is shown as well as the validity and reliability of proposed relationships. `Serene', `space', `prospect', `rich in species' and `nature' were the most influential PSDs on PRE through their higher effect on perceived characteristics of `fascination' and `compatibility'. These results provide information within landscape architecture and planning to promote the development of open spaces as resources for psychological restoration and stress relief.
Development of Understanding Zero
Authors: Krajcsi Attila , Kojouharova Petia , Lengyel Gabor
Published: August 2017

While the knowledge about the development of understanding positive integers is rapidly growing, the development of understanding zero is not well-known. Here we tested several components of preschoolers’ understanding zero: whether they can use empty sets in numerical tasks, whether they can use empty sets as soon as they understand the cardinality principle, whether they know what the word “zero” refers to, and whether they categorize zero as a number. The results show that preschoolers can handle empty sets in numerical tasks as soon as they understand the cardinality principle or even earlier, and some of them know that these sets are labeled as “zero.” However, they are unsure whether zero is a number. We argue that preschoolers might understand numbers as the properties of items or objects in a set. In this view, zero cannot be a number, because an empty set does not include any items, and the missing items cannot have any property, excluding also the number property. This model might explain why zero is handled correctly in numerical tasks, while it is not regarded to be a number.

The validity of qualitative data obtained through the extention of time doing research and triangulation of data collection techniques and data sources in the field. The result show: Interpersonal communication in PSKD Mandiri Schools is the result of a  good engagement between teachers and parents. Parents understand the  procedures how to make a contact with teachers. Parents are also free to choose the communication channel that they desired. Schools encourage the use of technology in the  communication between home – school. Several form of written communication have been considered including handbooks, newsletter, progress reports and home – school diaries.  Guidelines have been also provided for the use of  telephone contacts with parents and for the use of new technological option such as school website, e-mail, ans text messaging. Therefore, it is considered that making a range of strategies available to parents will lead to optional levels of parental involvement in school. However the range of strategies used by the school will mostly be dependent on teachers’s knowledge of and skills for effectively implementing the various strategies.  The wide range of activities is also used by school to bring about high levels of parental involvement.

Rigging the Odds Against Climate Change
Authors: Barrow Ellen , Tarplee Ian
Published: August 2017

Climate change has enormous potential to impact on many types of ecosystem, not least our ocean environments. Melting ice caps, increasing sea temperatures and more extreme weather events mean that it is imperative that our marine-based infrastructure is resilient to withstand these challenges, both in the short-term and long-term future.

Offshore platforms are a haven for marine life. Have we considered how biological activity, arising as a result of climate change, could affect the structural integrity of the marine infrastructure we build? Does the design basis for marine infrastructure account for additional biological hazards arising as a result of increasing sea water temperatures? What are the implications for the life of the platform? Do current plans for decommissioning, and/or life extension, need to be reconsidered to avoid escalating and unforeseen costs? Climate change is unpredictable; we must factor in the likelihood of both extreme and gradual changes.

In this paper we tackle increasingly important issues: what would the impacts be on critical seawater abstraction points due to invasive species, excessive marine growth or jellyfish swarms? Would our oil platforms stand up to an extreme wave with many unaccounted for tonnes of marine growth? Would these additional tonnes of marine growth threaten structural integrity and mean additional millions to cover the costs of decommissioning the rigs? Will biologically induced hazards reduce the life of offshore assets and/or challenge assumptions for life extension of assets? We suggest that if engineers consider these potential, and highly likely, concerns at an early stage, timely and costly delays to operations and decommissioning may be avoided.

Using real examples we will explore practical solutions to the increasingly prevalent biological challenges facing marine infrastructure as a result of climate change. These practical challenges will be discussed with a focus on decommissioning and life extension of assets, taking into account unanticipated loads for lifting, increased problems regarding disposal of marine growth, further structural maintenance and the unwelcome costs these may all introduce.

Authors: Okenyi Kingsley , Apena Abayomi , Emifoniye Ejiro , Ognane Edgar Mba , Ogbodu Ejiro , Ukponmwan Aihanuwa
Published: August 2017

In 2012, a benchmarking exercise was conducted to assess the performance of Bonga wells, a Deepwater (DW) project in Nigeria. The review revealed that the average Bonga well ranked fourth Quartile when compared with similar DW wells globally. After reflecting on the benchmark results, the Bonga Wells team concluded that something drastic needed to be done urgently to reverse the trend otherwise future projects will become unattractive and the profitability of the Bonga Field will be impacted negatively. Late 2012, a clear steer was given by Bonga Wells Leadership to reverse the performance trend. The mantra for the team was to beat the best performance anywhere in the world and there was a very strong leadership commitment to make it happen. The team concluded with a target to deliver ‘best in class' wells consistently within 24 months.
Roadblocks to Automation of Tubular Running Operations
Authors: Schmidt H. W. , Savini M. B. , Begnaud B. D. , Brown D. H. , Roy C. H.
Published: August 2017

Remote control and automated systems affiliated with Tubular Running Operations have been in use for the past 15 years with varied levels of success. Unsuccessful implementations have not elicited solutions, nor have successful implementations translated into a thriving industry standard. Though the oil and gas industry has changed much over the past 15 years, some of the same implementation challenges still exist. Service providers tend to have a "scattershot" approach to automating everything, rather than a concerted focus on exploiting small successes to realize specific company goals. This factor may be due to differing attitudes throughout the organization, ranging from upper management to business development to engineers. This can lead to the inability to cultivate a culture of technical progression among operators commensurate with the technical progression of equipment. From the service provider's perspective, an unwillingness to learn new technical concepts among operators may yield a general indifference about their own relevance within an automated industry, while the end customer may remain skeptical of the need for automation and become dissatisfied with the overall cost and time needed to implement automated solutions. Historically, industry insiders tended to mistake automation's inability to yield operational efficiency immediately as a failure. Overlooked is the fact that even the most cleverly implemented automation realizes better operational efficiency over time, with constant improvements and further integration. Additionally, some clients fail to realize that control systems are inconsistent from rig to rig. The absence of standardization may stem from corporations assigning more value to the retention of trade secrets than to an industry-wide focus on standardization. The following paper will examine—from the Tubular Running Services (TRS) provider perspective—the challenges associated with developing and deploying remote control and automated equipment. It will also give pragmatic solutions towards the successful implementation of this technology and prove that automation is not solely a technical hurdle for engineering to overcome.

Published: August 2017

Background:

Cyperus rotundusL. (Cyperaceae), is a perennial sedge distributed throughout India and other parts of the world. Its tubers are used as an appetizer, febrifuge and to treat bleeding, blisters, boils, cough, diarrhea, inflammation, lacteal disorders, rheumatoid arthritis, stomach ailments, skin rashes, thirst, vomiting, worm infestation and wounds.

Objective:

Our study was planned to isolate chemical constituents from the rhizomes ofC. rotundusand to characterized their structures.

Method:

The air-dried rhizome powder was exhaustively extracted with methanol in a Soxhlet apparatus. The concentrated methanol extract was adsorbed on silica gel (60-120 mesh) for the preparation of a slurry. The dried slurry was chromatographed over silica gel column packed in petroleum ether. The column was eluted with petroleum ether, chloroform and methanol, successively, in order of increasing polarity to isolate the compounds.

Results:

Phytochemical investigation of the tubers led to isolate a sesquiterpenone characterized as 12-methyl cyprot-3-en-2-one-13-oic acid (1), two aliphatic ketone viz.n-dotriacontan-15-one (2) andn-tetracontan-7-one (8), fatty estersn-pentadecanyl octadec-9, 12- dienoate (n-pentadecanyl linoleate,3),n-hexadecanyl linoleate (4),n-hexadecanyl oleate (5) andn-pentacos-13ʹ-enyl octadec-9-enoate (n-pentacos-13ʹ-enyl oleate,9), two steroidal estersstigmast-5,22–dien-3β–olyln-dodecanoate (stigmasterol laurate,6) and stigmast-5, 22-dien-3β-olyln-tetradecanoate (stigmasterol myristate,7), β-sitosterol-3β-O-glucoside(10)and a triterpenic glycosidic ester lup-12, 20 (29)-dien-3β-ol-3-α-L-arabinopyranosyl-2'-oleate (lupenyl 3β-O-arabinpyranosyl 2′-oleate,11). The structures of these compounds were established by spectral data analysis and chemical reactions.

Conclusion:

A sesquiterpene identified as cyprot-3-en-2-one-14-oic acid, two aliphatic ketones, fatty esters, two steroidal esters, β-sitosterol-3β-O-glucoside and lupenyl 3β-O-arabinpyranosyl 2′-oleate were isolated for the first time from the rhizomes.
Chlorella vulgaris as a Source of Essential Fatty Acids and Micronutrients: A Brief Commentary
Authors: Freitas Hércules Rezende
Published: August 2017

Polyunsaturated fatty acids (PUFAs) comprise about 35-40% of the total lipid content from green algaeChlorella, reaching up to 24% linoleic acid and 27% α-linolenic acid inC. vulgaris. Also, microalgae nutrient composition may be modulated by changes in the culture medium, increasing fatty acid and microelement concentrations in the algae biomass. PUFAs, such as α-linolenic (n-3) and linoleic (n-6) acids, as well as its derivatives, are considered essential for dietary consumption, and their ability to regulate body chemistry has been recently explored in depth. A balanced fatty acid consumption is shown to counteract the negative effects of western diets, such as chronic inflammation and glucose intolerance. In this brief commentary, technological and practical uses ofC. vulgarisare explored as means to improve dietary quality and, ultimately, human health.

Published: August 2017

Background:

Bentonite clays are widely used in a drilling operation and play a vital role as a drilling fluid. Bentonite clay mud performs several functions during the drilling operation and facilitates the drilling process.

Objective:

In this study, the locally available raw bentonite clays were investigated to evaluate its potential use as a mud for borehole drilling operation after its improvement with the additives.

Method:

Rheological properties such as plastic viscosity, yield point and gel strength were evaluated by using a viscometer and filtrate loss test was performed by using filter press on both locally available raw bentonite clays and the commercial bentonite named as Mill gel.

Results:

From the test results obtained for the up gradation of clays with the different beneficiating materials, the drastic increase in the plastic viscosity, yield point and gel strength has been observed. It shows that Xanthum gum produced better results for the improvement of rheological properties of such clays. Carboxymethyl cellulose and starch were used as additives and it has been observed that carboxymethyl cellulose has improved both viscosity and filtrate loss control, whereas starch muds have the best filtration control properties.

Conclusion:

Improved bentonite clays have rheological and filtration characteristics that have satisfied American Petroleum Institute specification at optimum conditions of clay. It was concluded that improved clays are the suitable material for the drilling operations and suitable to substitute commercial bentonite.

Authors: Melo de Oliveira Rafael , Carreiro Lermen Daniel , Augusto Marson Runer , Borba Neves Eduardo
Published: August 2017

La propuesta de este estudio fue comparar la influencia del calentamiento activo con y sin estiramiento estático en los valores de torque generados en el equipo isocinético para la articulación de la rodilla. Se trata de un estudio transversal, comparativo, que evaluó la fuerza máxima de los extensores y flexores de la rodilla en un dinamómetro isocinético a la velocidad de 60°/s. Se evaluaron doce militares, todos del sexo masculino, con una edad media de 25 ± 2,5 años. En relación con la masa corporal y la estatura, los valores de la media y la desviación estándar fueron: 75±7,5 kg y 1,71±0,1 m. Se observaron diferencias significativas en los valores del pico medio de par de los extensores de la rodilla (p=0,034), flexores de la rodilla (p=0,028) y valores del pico máximo de torque de los flexores de la rodilla (p=0,034) entre las pruebas precedidas de calentamiento con estiramiento estático y aquellas precedidas de calentamiento sin estiramiento. No hubo diferencia significativa en los valores del pico máximo de torque de los extensores de la rodilla (p=0,071). Se puede concluir que el calentamiento activo con estiramiento estático antes de la prueba de fuerza máxima en el isocinético (60º/s) promueve un aumento en los valores del pico de torque de los extensores y flexores de la rodilla tanto en los valores medios como máximos, en términos absolutos, aunque el pico de par máximo de los extensores no haya presentado diferencias significativas.

La dimensión estratégica de actividades en China en el sector de telecomunicaciones latinoamericano
Authors: Evan Ellis Robert
Published: August 2017

La presencia de empresas chinas en los sectores de telecomunicaciones podría decirse que tiene un carácter doblemente estratégico. Por un lado, la expansión y acumulación de la capacidad tecnológica de las empresas chinas en esos sectores, beneficia la modernización y la diversificación de la economía china y su enrutamiento hacia la competitividad basada en mejoras salariales, para así lograr la sofisticación y la capacidad de sus productos. Adicionalmente, la capacidad de las empresas chinas en estos sectores, en particular en América Latina, también tiene una importancia estratégica desde el punto de vista de la forma en que esas capacidades podrían ser utilizados por el Estado chino en la actual competencia global amistosa entre la República Popular China y los Estados Unidos, derivando en algo más que una confrontación.

We consider a discrete time branching process where the population consists of k types of convergent products, an action is chosen for that which affects the lifetime, the number and types of its functions, and the profit received. The problem of maximizing the expected profit is shown to be equivalent to a generalized Markov decision problem of maximizing the expected profit is shown to be equivalent to a generalized Markov decision problem where the  transition matrices are non-negative but not necessarily sub stochastic.

A hipótese de eficiência do mercado em sua forma semiforte, alvitra que os preços se ajustam instantaneamente refletindo a divulgação pública de quaisquer informações relevantes, coibindo oportunidades de retornos anormais arbitrários. O objetivo deste estudo é verificar a ocorrência de variação no preço das ações, por ocasião da Oferta Pública de Aquisição de Ações (OPA), no mercado acionário brasileiro, no período entre 2006 a 2015. A metodologia da pesquisa utilizada é o estudo de eventos para avaliar possibilidade de retornos anormais de ativos em relação ao mercado. Esta pesquisa se distingue pela quantidade de OPAs (65) ocorridas em um longo período (10 anos) estudados, contribuindo pela agregação, ao aproximar-se da curva normal. Foram testadas as variações no preço das ações no período que antecedeu, durante e imediatamente após o evento. Os resultados encontrados, em relação ao evento de OPA, evidenciam que, em sua maioria, há significância estatística de variação no preço destas ações. A conclusão é que há evidências da hipótese de eficiência do mercado brasileiro em sua forma semiforte, no período estudado, ocasionada pelo evento das OPAs.

The Prunus_armeniaca fruit is classified manually in wholesale markets, supermarkets and food processing plants on a normal or defects basis. The aim of this research is to replace the manual sorting techniques using computer vision techniques and applications by proposing techniques for identify and recognitions patterns through the use of 150 fruits of Prunus_armeniaca, 10 for the testing stage in fresh and 10 for testing stage in case of defects. The fruits Prunus_armeniaca collected from growing trees in the large fields of Salah al-Din province\Iraq. The system designed for classification based on the color image taken inside a black box used camera pixel resolution of (13 mega) with a constant intensity of light. . Used K-mean in phase segmentations and only computed 13 features derive statistics from GLCM .classification phase used SVM classify fruit into two class, either (normal or defects) .Results the system success rate reach 100%.The work done using MATLAB R2016a.
Successful Data Science Projects: Lessons Learned from Kaggle Competition

Published: August 2017

The workflow from data understanding to deployment of an analytical model of a data science project begins at framing the problem at hand, a task that is typically business-oriented and requires human-to-human interaction. However, the next three steps: data understanding, feature extraction, and model building that come next in the pipeline are the key to successful data science projects. Failing to fully understand the requirements of each of these three steps can negatively affect the performance of the proposed system. Hence, the current study tries to answer the following question “What are the requirements of a successful data science project?” To answer this question, we will use the solution that we built to measure the relevance of local search results of small online e-businesses and submitted to Kaggle data science platform to shed light on why our solution did not achieve a top position among other competitors. Evaluation of the design that we submitted to the competition is going to be carried out in the spirit of the three winning submissions. Our results revealed that well-performed data preprocessing, well-defined features, and model ensembling are critical for building successful data science projects. Such a clarification provides insight into specific aspects of model design to help others including Kagglers avoid possible mistakes while approaching their data science projects.
