Authors: De Sousa Augusto Rodrigues , Felzke Lediane Fani
Published: March 2021

Esse artigo apresenta os resultados de três rodas de conversa realizadas com alunos do ensino técnico integrado ao médio do Instituto Federal de Rondônia (IFRO), Campus Porto Velho Calama, nas quais foram discutidas as percepções dos alunos acerca das temáticas referentes às relações étnico-raciais. A metodologia proposta é de natureza qualitativa e caráter exploratório e participante, a partir de uma percepção decolonial e afrocentrada dos processos de produção do conhecimento. Como resultados de nossas análises constatamos que os alunos consideram importante o trabalho em torno das referidas temáticas, reconhecem o processo de apagamento que ainda se mantém acerca das mesmas e propõem possibilidades pedagógicas integradas voltadas para a interdisciplinaridade.
A prática de slam no ensino de literatura na EJA: refletindo um currículo antirracista
Authors: Torres Giovanna Medeiros , Benvenuti Juçara
Published: March 2021

Esse relato de experiência traz resultados obtidos a partir do sarau antirracista realizado na véspera do dia consciência negra, no dia 19 de novembro de 2019, com os alunos da modalidade de Educação de Jovens e Adultos (EJA) do Colégio de Aplicação (CAp/UFRGS). A atividade buscou potencializar ações de educação para as relações étnico-raciais, especialmente no que se refere ao ensino de literatura. A participação do convidado Ariel Freitas, ativista, jornalista e poeta, trouxe a prática de poetry slams, sendo essa uma categoria literária ainda pouco reconhecida em ambientes tradicionais, surgida a partir de competições de poesia falada, e que “vêm figurando entre as mais inventivas e democráticas práticas da poesia performática em todo o mundo, com notáveis aspectos sociais, culturais, políticos e artísticos[1]”. Busca-se, a partir desse relato, promover uma reflexão acerca da necessidade de incluir cada vez mais pautas raciais no currículo do ensino básico, pensando especialmente a categoria da EJA, a mais atingida pelo analfabetismo, e nos empecilhos que muitos alunos encontram para acessar uma ferramenta básica e essencial para o pleno exercício da cidadania: a escrita.[1] D’ALVA, Roberta Estrela.

Published: March 2021

Submersion and exposure from the operation of the Three Gorges Reservoir
(TGR) can alter soil properties and plant characteristics at different
elevations of the water level fluctuation zone (WLFZ), possibly
influencing soil detachment capacity (Dc), but the vertical
heterogeneity of this effect is uncertain. Soil samples were taken from
6 segments (5 m elevation per segment) along a slope profile in the WLFZ
of the TGR to clarify the vertical heterogeneity of Dc. Scouring
experiments were conducted at 5 slope gradients (17.63%, 26.79%,
36.40%, 46.63%, and 57.74%) and 5 flow rates (10, 15, 20, 25, and 30
L min–1) to determine Dc. The results indicate that the soil properties
and biomass parameters of the WLFZ are strongly affected by elevation.
Dc fluctuates with increasing elevation, with maximum and minimum
average values at elevations of 145-150 m and 165-170 m, respectively.
Linear equations accurately describe the relationships between Dc and
hydrodynamic parameters. τ, ω, and E perform much better than U.
Furthermore, a clear improvement is seen when using the general index of
flow intensity to estimate Dc. Dc is significantly negatively correlated
with MWD (p < 0.05) and organic matter (p < 0.01)
but not significantly correlated with other soil properties (p
> 0.05). At elevations of 145-150 m and 170-175 m, rill
erodibility was greater than at other elevations. The critical hydraulic
parameters were highest in the 165-170 m segments, both showing
obviously fluctuation in the vertical direction of slope surface. This
research highlighted the vertical heterogeneity of the soil detachment
and was helpful to understand the mechanisms of soil detachment
processes in the WLFZ of the TGR.

Published: March 2021

Aim: The Norwegian Association for Clinical Pharmacology in their
National Guidelines decreased therapeutic range (TR) of topiramate (TPM)
from 5-20 mg/L to 2-10 mg/L. The objective of this study is to ascertain
which TR produces better clinical outcomes. Methods: Data source were
request forms for routine therapeutic drug monitoring of TPM.
Concentration dependent adverse drug reactions (ADRs) were evaluated in
1,721 samples taken pre-dose. Seizure frequency analysis was performed
in 294 samples of monotherapy. Statistics: Prism 5.0, GraphPad Instatt:
Mann–Whitney U test for median plasma level (PL). χ2-test for seizure
frequency and for distribution of PL according to TR 5-20 mg/L and
intervals <2, 2-5, 5-10, 10-20, >20 mg/L.
Results: Better seizure control was found in children both in whole
cohort (without seizure 49% vs 37% adults), as well as in monotherapy
(56% vs 44%), in children with PL 5-20 mg/L vs 5 mg/L (65% vs 44%)
and in children with PL 5-10 mg/L vs <2 mg/L. Seizure-free
children had higher PL than those with seizure yearly: median (lower,
upper quartile) [mg/L]: 5.5 (3.4-6.5) vs 4.7 (4.3-7.95). No
difference was found in adults. Seizure control was poorer in all
patients with PL <2 mg/L compared to 5-10 mg/L; and 10-20
mg/L; further in PL within 5-10 mg/L vs 10-20 mg/L; and in the period
2003-2005. ADRs reported in 38 samples (2.8%) were without relation to
PL. Conclusions: Change of TR is not recommended.

Vision on a Digital Twin of the Road-Tire-Vehicle System for Future Mobility
Authors: Kaliske Michael , Behnke Ronny , Wollny Ines
Published: March 2021

Innovative trends such as autonomous cars and smart vehicles have gained increasing attention and will form a new mobility technology. At the same time, the appearance of smart tire systems will give rise to better tire performance, better vehicle control, and the enhancement of current intelligent systems for autonomous vehicles. In contrast, innovations for the road system, which must carry the increasing traffic loads, have been rare in recent years. However, to solve current and future challenges of mobility related to road transport (e.g., durability, safety, efficiency, ecology, cost, etc.), the potential for innovative trends and digitalization of all interacting components—vehicle, tire, and road—should be used to change the industrial ecosystem and paradigm of transport in human life. The vision of a digital twin of the road system, which is the digital/virtual image (reality model in space and time) of the vehicle, tire, and roadway, would enable, among other aspects, the future pioneering condition predictions of single components (ranging from manufacturing, service to failure state), targeted traffic control, optimal synthesis of building materials and structures, interfaces to automated driving, as well as reduction in emissions. The digital twin of the road system contains and combines all available and relevant information about the “road of the future” system from physical examinations and modeling as well as from data-driven models and further available data (e.g., real-time sensor data from the vehicle, tire and road sensors, data models, etc.). This contribution presents the current state of research, tasks, and challenges toward achieving the digital twin of the road system as well as the potential of the digital twin for future mobility.

Authors: Abdullah Hanisah , Low Fook Lee Jeffrey
Published: March 2021

The purpose of this study was to examine the effects of analogy and explicit instructions on 50-m sprint performance and their running kinematics. Forty-five male Physical Education undergraduates participated in this study and were randomly divided into three groups, (i.e. analogy, explicit and control). Their sprint performances were assessed using wireless timing gate while the kinematic data was assessed by Kinovea software. The analogy group received three analogies which were “run tall”, “chin to pocket” and “claw the track” throughout the intervention sessions whereas the explicit group received “keep the body posture in an upright position and aligned, head and butt not tilting outward”, “arms should maintain a 90-degree angle at the elbow throughout the upswing as well as backswing” and “the foot landing should always be on the balls of the feet”. The control group did not receive any instruction throughout the intervention period. All participants were tested again after three weeks for the post test and retention test a week after. A 3 group x 3 tests mixed design ANOVA was used to analyze the sprinting performance whereas the kinematic data was analyzed by using one way MANOVA test. Results displayed that there was no significant difference in sprint performance among the groups. However, the post hoc test showed that the analogy group improved significantly in the post test. The kinematic data showed that both intervention groups were significantly better than the control group. This study concluded that both analogy and explicit instructions resulted in better running mechanics but only the analogy group elicited better in performance. Thus, analogy instructions are suggested to be an effective method to coach sprinters.

Authors: A Halim Nur Asmidar , Ismail Mazlan
Published: March 2021

Practice in Mind (PIM) training help to resolve physical and psychological problem in sport skills performance. Therefore, the present study was done to investigate the effectiveness of PIM training on netball standing shot and jump shot performances. Twenty state level netball shooters with 3 to 5 years playing experiences participated in this experimental study. Participants were randomly assigned into PIM training group and control group with 10 participants for each group. Both groups completed 18 training sessions in 3 times a week for 6 weeks intervention program. Pre, post, and retention test were conducted prior to the 10 standing and jump shooting task. The results revealed that there was significant different of PIM training group versus control group for both standing shot (p < .05) and jump shot (p<.05) after 6 weeks. However, no significant different was observed after retention (week 12) for both groups. Based on the finding, it is suggested this present study will be beneficial to the athletes in terms of educating them about the importance of systematic imagery training to increase shooting performance in netball and for further improvement on their shooting techniques. Future studies are warranted to explore potential benefits of PIM training by focusing on a larger exposure and other netball specific motor-abilities.

Las raras. Parentescos femeninos, mediaciones discursivas y tensiones de época en «Confesiones de Dorish Dam» de Delia Colmenares y «Las memorias de Mamá Blanca» de Teresa de la Parra
Authors: Huaytán Martínez Eduardo Miguel
Published: March 2021

Confesiones de Dorish Dam (1929) de Delia Colmenares (1887-1968) y Las memorias de Mamá Blanca (1929) de Teresa de la Parra (1889-1936) son dos novelas que reaccionan a las nuevas tendencias surgidas en la segunda década del siglo XX, explícitamente en el caso de las vanguardias e implícitamente en el caso del regionalismo. En este artículo, propongo, más bien, que se encuentran cercanas a la estética modernista y posmodernista. Ambas, a su vez, ficcionalizan géneros menores como el diario y las memorias para crear una alianza de género no exenta de tensiones. Además, desde una mirada sui generis y en un contexto de modernización, construyen personajes femeninos alternativos, disidente en de la Parra y transgresor (lesbiana) en Colmenares.
Alimentar a otros para alimentar a los propios: dualidades y desigualdades de la venta del trabajo de alimentar en la Ciudad de México
Authors: Villagómez Ornelas Paloma
Published: March 2021

El trabajo informal urbano ha sido poco estudiado en términos de las experiencias de sus actores. Este artículo analiza el caso de mujeres de estratos populares dedicadas a la venta de alimentos. El objetivo es describir la interacción entre el trabajo alimentario remunerado y no remunerado y sus efectos en la posición de género y clase de las mujeres. Mediante el análisis de entrevistas muestro que el trabajo de alimentar desarrolla dualidades subjetivas que se coproducen entre lo doméstico y lo público: en ambos espacios persiste la desvalorización del trabajo reproductivo, pero también en ambos éste puede ser fuente de orgullo y reconocimiento. El sentido que predomine en el balance depende de los recursos disponibles, la capacidad para movilizarlos y los rendimientos obtenidos en los negocios emprendidos.
Study the effect of Welding Current on the microstructure and strength of dissimilar weld joint AISI 303/AISI 1008
Authors: Hameed Firas
Published: March 2021

The welding of metals is one of the most important processes that require high control for obtaining a good quality of weldments. The joining of dissimilar metals is a more complex operation compared to the joining of similar metals due to the differences in physical metallurgical and mechanical properties. In this article, austenitic stainless steel AISI 303 stud was welded to low carbon steel AISI 1008 plate using arc stud welding (ASW) process. An experimental procedure was applied to estimate the effect of welding parameters namely welding current and welding time on the microstructure and mechanical properties of the joint. The optical microscope V83MC50 was used to show microstructure properties while both the micro-Vickers Hardness and tensile test were adopted to evaluate the mechanical properties. The results revealed that the presence of carbides at the fusion zone FZ towards AISI 303 leads to the maximum value of hardness (501) HV. The best welding parameters were 600 AMP 0.25 second at which joint strength of 515 MPa was recorded. Welding time was the most important parameter in the ASW process followed by welding current, proper selection of welding time, and current welding produces good joint quality

Object and purpose of research. This paper discusses structural materials under cyclic load. The purpose is to determine the minimum fatigue life corresponding to a certain non-exceedance probability of this value. Materials and methods. The study was performed on three structural materials: steel 15ХМ, steel 08Kh18N10Т and titanium alloy PТ-7М. Initial estimate of fatigue life distribution parameters relied on the data about guaranteed maximum and minimum values of temporary resistance and relative cross-section tapering. The assessment was performed as per a common curve “conditionally elastic stress amplitude versus number of cycles to failure” taking into account the mechanical prop-erties of given material. The values of minimum fatigue life were obtained as per two different methods: statistical simulation of the random values following the Weibull distribution law and the analytical expression for probability density of the lows for given distribution function of random value and fixed scope of sampling. Main results. The lows yielded by statistical simulation are more conservative than those yielded by the analytical formula. The margin in terms of the number of cycles to failure stipulated as 10 in several regulatory documents seems to be somewhat unsubstantiated. This margin is too great in the low-cycle domain and too small in the high-cycle one. Conclusion. This paper postulates the existence of guaranteed maximum and minimum values for mechanical properties of structural materials, namely temporary resistance and relative cross-section tapering. These values were applied to well-known analytical curves of fatigue, which finally yielded possible variation ranges for fatigue life at various amplitudes of conditionally elastic reduced stresses, assuming the existence of a certain shift in the sensitivity limit of fatigue life distribution. These data were further used to establish standard deviations and mathematical expectations for the number of cycles to failure.

Problems of jurisdiction in disputes involving a self-employed individual as a special subject of economic activity with an undefined legal status
Authors: Shapsugova Marietta Damirovna
Published: March 2021

Due to proliferation of the experiment on introduction of special self-employment tax regime across the Russian Federation, the number of self-employed individuals is expected to rise. Moreover, the lockdown brought on by the current pandemic led to a sharp increase in self-employment. This circumstance makes the subject of this research more relevant – the questions of legal status of self-employed individuals in connection to their financial-legal and procedural-legal aspects. The article analyzes the doctrinal approaches towards definition of jurisdiction, the use of which allows overcoming current legislative gap. Research is conducted on the normative act and case law of the Constitutional Court of the Russian Federation that forms the conceptual approach towards self-employment. For the first time, the activity of a self-employed individual is examined in relation to the concepts of economic, entrepreneurial, and professional activities. The problem of undefined procedural status of a self-employed individual is explored in conjunction with its undefined status in the substantive law. A conclusion is made that such activity should be classified as economic. The scientific novelty consists in posing the question of jurisdiction of disputes involving self-employed individuals. The author concludes on undefined nature of self-employed individual in the substantive law, which leads to legal uncertainty of their procedural status. The uncertainty is expressed in the absence of rules of jurisdiction over disputed involving self-employed individuals. The author makes proposal for changes to procedural legislation.

The city centre is a most valuable, historically formed area of living and commercial space. However, urbanistic policies of cities do not pay enough attention to maintaining or creating appropriate living conditions for the inhabitants of city centres, while still protecting and taking into account the aesthetic and design-related assets. A chaotic management of historic city centres and the lack of appropriate spatial regulations lead to frequent conflicts and eventual withdrawal of inhabitants from the area. This article aims to identify problems specific to city centres and to show that improving the living conditions thereof is possible, which will definitely lead to city centres keeping their housing function and encourageresidents to settle within.
Gra o przestrzeń publiczną miast

Published: March 2021

Przestrzeń publiczna do niedawna traktowana jako „państwowa”, tzn. dla większości „niczyja”, w okresie przemian ustrojowych nabrała istotnego znaczenia. Stała się areną starć pomiędzy różnego rodzaju „graczami”. W walce o przestrzeń publiczną ścierają się interesy między innymi władz samorządowych, prywatnych inwestorów i mieszkańców. Inwestycje w przestrzeni publicznej sprawiają, że w ciągu ostatnich lat podlega ona dynamicznym przemianom. Kto ostatecznie decyduje o wyglądzie przestrzeni publicznych i funkcjach, jakie one pełnią? Czy zawsze są one zgodne z oczekiwaniami odbiorców? W pierwszej części opracowania przytoczono definicje przestrzeni publicznej oraz omówiono problematykę przestrzeni semipublicznych. W drugiej części pracy skupiono się na omówieniu głównych „graczy” o przestrzeń publiczną miast, przedstawiono motywy ich działania oraz preferencje w gospodarowaniu przestrzenią, a także przedstawiono przykłady przemian przestrzeni publicznej miast będące często wynikiem gry interesów.
Programowanie rewitalizacji a proces zmiany miasta – z perspektywy doświadczeń w partycypacyjnym planowaniu zagospodarowania przestrzennego w wybranych polskich miastach
Authors: Mliczyńska-Hajda Dagmara
Published: March 2021

Rewitalizacja jako metoda interwencji w zdegradowanych dzielnicach miast lokuje się z trudem w arsenale metodycznym planowania zagospodarowania przestrzennego. Trafia przez to najczęściej do kategorii „instrument naprawczy”, reaktywny. Oczekuje się, że program rewitalizacji wyzwoli te spośród endogenicznych zasobów, które zdołają zniwelować skutki degradacji społeczno-gospodarczej i zmienią tylko tę część miasta, hamując niekorzystny bieg rzeczy. Artykuł przedstawia obserwacje i wnioski z partycypacyjnego programowania procesów rewitalizacji w dwóch polskich miastach, podjętych i przeprowadzonych z uwzględnieniem wywołania zmiany przestrzennego zagospodarowania w skali szerszej, wykraczającej poza postulat przywrócenia status quo i naprawy zniekształconych relacji funkcjonalno-przestrzennych.

Na współczesnym rynku usług turystycznych jednym z głównych elementów decydujących o sukcesie lub porażce przedsięwzięcia hotelarskiego jest jego lokalizacja. Szczególne znaczenie ma to na obszarach miejskich, gdzie konkurencja jest bardzo duża, a hotele często oferują podobny standard i jakość usług; tu dogodne usytuowanie może być kluczowym czynnikiem wyboru danego obiektu. Artykuł przedstawia najważniejsze aspekty lokalizacji hoteli. Problematyka rozpatrywana jest w dwóch płaszczyznach: ogólnej – dotyczącej wyboru kraju i regionu – oraz lokalnej – dotyczącej konkretnego miejsca, konkretnej lokalizacji danego hotelu. Na podstawie analizy literatury przedmiotu wskazano istotne tendencje odnoszące się do lokalizacji hoteli, ze szczególnym uwzględnieniem dużych ośrodków miejskich. Rozważania teoretyczne potwierdziły potrzebę prowadzenia dalszych studiów, w tym w konkretnych przykładowych miastach, ze względu na fakt, że baza noclegowa ulega dość szybkim zmianom i pojawiają się nowe obszary koncentracji usług hotelarskich.
Obszary funkcjonalne i ich związki z zasięgiem oddziaływania ośrodków subregionalnych (na przykładzie województwa opolskiego)
Authors: Heffner Krystian , Gibas Piotr
Published: March 2021

Obszary funkcjonalne powiązane z miastami cechują się różnym poziomem rozwoju, a jednym z głównych celów polityki regionalnej jest zmniejszanie różnic w tym względzie. Celem opracowania jest identyfikacja procesów integracyjnych zachodzących między jednostkami tworzącymi miejskie obszary funkcjonalne oraz określenie ich zasięgów. W szczególności skupiono się na rozpoznaniu intensywności powiązań oraz na stworzeniu i weryfikacji listy kryteriów umożliwiających jednoznaczną delimitację obszarów funkcjonalnych ośrodków subregionalnych. Założono, że każdy ośrodek metropolitalny, krajowy i wojewódzki spełnia także funkcje na poziomie subregionalnym.
Delimitacja obszarów funkcjonalnych małych i średnich miast w regionie łódzkim
Authors: Bartosiewicz Bartosz
Published: March 2021

Celem opracowania jest delimitacja obszarów funkcjonalnych małych i średnich miast regionu łódzkiego. Artykuł stanowi część szerszego badania poświęconego delimitacji miejskich obszarów funkcjonalnych w całej Polsce. Najważniejszym elementem analizy jest propozycja autorskiej metody delimitacji obszarów funkcjonalnych małych i średnich miast z zastosowaniem powiązań funkcjonalnych. Badania testowe zaprezentowane w artykule są prowadzone na zbiorze 25 ośrodków miejskich województwa łódzkiego. Wnioski płynące z badania wskazują, że to nie wielkość, liczona liczbą mieszkańców, jest decydującym czynnikiem kształtującym zakres przestrzenny miejskich obszarów funkcjonalnych. Większą rolę odgrywa położenie miasta oraz jego funkcja administracyjna.
Powiązania funkcjonalno-przestrzenne w świetle dojazdów do pracy
Authors: Ilnicki Dariusz , Michalski Piotr
Published: March 2021

Badania wielkości i kierunków dojazdów do pracy po II wojnie światowej były możliwe do 1988 r. Kolejne dane umożliwiające badanie powiązań funkcjonalno-przestrzennych pojawiły się dopiero po blisko 20 latach. W chwili obecnej Główny Urząd Statystyczny udostępnia wyniki przeprowadzone w 2006 i 2011 r. badań dojazdów do pracy. Dane te obejmują dojazdy do pracy jedynie dla strumieni przemieszczeń powyżej 9 osób. Tym samym nie pozwalają określić pełnych powiązań funkcjonalno-przestrzennych. Różna metodologia szacowania wielkości dojazdów do pracy nie pozwala na stwierdzenie, jaka jest główna przyczyna „wzrostu” ruchliwości przestrzennej między miejscem zamieszkania a miejscem pracy. Głównym celem pracy jest odniesienie się do wartości poznawczej i aplikacyjnej dostępnych danych o wielkości dojazdów do pracy. Równocześnie poprzez analizy wybranych aspektów dojazdów do pracy wskazano na te, które mogą mieć największą wartość poznawczą i aplikacyjną. Krytyczna analiza źródeł nie dyskwalifikuje prowadzenia badań na ich podstawie. Jednak konieczne jest ponowne włączenie problematyki dojazdów do pracy do Narodowego Spisu Powszechnego. Badania muszą objąć wszystkich dorosłych obywateli, a nie być jedynie badaniem reprezentatywnym, którego wyników nie należy odnosić do innych tego typu badań
Wpływ zapisów miejscowych planów zagospodarowania przestrzennego na rozwój strefy podmiejskiej Wrocławia
Authors: Michalski Piotr , Ilnicki Dariusz
Published: March 2021

Przestrzeń polskich miast i terenów przylegających do ich granic podlega stałym przekształceniom. Po przemianach ustrojowych, które zaszły w Polsce na przełomie lat 80. i 90. XX w., nasileniu uległy procesy suburbanizacyjne. Nierzadko można spotkać się z twierdzeniem, że suburbanizacja ma charakter niekontrolowany. Nie do końca należy się z tym zgodzić, ponieważ suburbanizacja jest efektem świadomych decyzji administracyjnych oraz wynikiem realizacji zapisów dokumentów planistycznych. W niniejszym artykule rozpatrzono treści uchwał i rysunków planów miejscowych obowiązujących w pięciu gminach powiatu wrocławskiego graniczących z Wrocławiem, tj.: Kobierzycach, Kątach Wrocławskich, Czernicy, Siechnicach, Długołęce. Ustalenia planów skonfrontowano z aktualnym stanem zabudowy mieszkaniowej w tych jednostkach. Wyniki przeprowadzonych analiz wykazały, że w przypadku realizacji zapisów z miejscowych planów zagospodarowania przestrzennego suburbanizacja w południowej i wschodniej części strefy podmiejskiej Wrocławia będzie się nasilać. Będzie to skutkowało m.in. trwałymi przekształceniami w strukturach funkcjonalno-przestrzennych poszczególnych miejscowości oraz zmianami w hierarchii układu osadniczego poszczególnych gmin.
The Application of Machine Learning Algorithm in Relative Permeability Upscaling for Oil-Water System
Authors: Wang Yanji , Li Hangyu , Tian Ji , Fan Ling , Xu Jianchun
Published: March 2021

Traditional two-phase relative permeability upscaling requires the fine-scale two-phase flow simulation over the target regions/blocks. It can be very computationally expensive especially for cases with multiple (hundreds of) geological realizations (as commonly used in subsurface uncertainty quantification or optimization). In this paper, we develop a machine learning assisted relative permeability upscaling procedure, in which the full numerical upscaling is performed for only a portion of the coarse blocks, while the upscaled functions for the rest of the coarse blocks are calculated by the machine learning algorithm. The upscaling procedure was tested for generic (left to right) flow problems using 2D models for scenarios involving multiple realizations. Numerical results have shown that the coarse-scale simulation results using the newly developed machine learning assisted upscaling procedure are of similar accuracy to the coarse results using full numerical upscaling. Because the fine-scale numerical simulation is only performed for a small fraction of the model, significant speedup is achieved.
Magnetic Flux Leakage Data Processing for Casing Inspection: An Inversion Approach
Authors: Assous Said , Whetton James , Bacciarelli Mark
Published: March 2021

Measurements of magnetic flux leakage are used extensively to map and monitor defects and corrosion in pipelines, well casings, and storage tanks. The application of this method enables locating defects and determining metal loss. The measurements have complex response characteristics, which must be understood to optimize measurement design and data processing choices. Until recently, the industry lacked an adequate first principles description of sensitivity to defect penetration and size, including the foundational cases of circular and elliptical defects. An inversion method has been developed and validated with independent synthetic and lab data. The data was obtained using an analytical forward model, finite element modeling, and laboratory data from different thickness and diameter pipes with known machined defects of different sizes and penetrations. The approach enables inverting field data to reconstruct 3D defect profiles, which helps to assess casing health and offers valuable information to the decision-maker for well integrity.

Published: March 2021

The recent global pandemic is an unprecedented event and took the world by storm. The Movement Control Order (MCO) issued by Malaysia's government to halt the spread of the deadly infection has changed the landscape of work via a flexible working arrangement. The Wells Real Time Centre (WRTC) is not an exception and is also subjected to the change. WRTC is an in-house proactive monitoring hub, built to handle massive real-time drilling data, to support and guide wells delivery effectiveness and excellence. The functionality of the WRTC system and applications are embedded in the wells delivery workflow. The centre houses drilling specialists who are responsible for observing the smooth sailing of well construction and are tasked to intervene when necessary to avoid any unintended incidents. WRTC is equipped with myriads of engineering applications and drilling software that are vital for the operations. Such applications include monitoring software, machine learning applications, engineering modules, real-time data acquisition, and database management. These applications are mostly cloud-based and Internet-facing, hence it is accessible and agile as an infrastructure that is ready to be deployed anytime anywhere when it is required. The strategy for WRTC mobility started as soon as the MCO was announced. This announcement mandated the WRTC to operate outside of the office and required the staff to work from home. The careful coordination and preparation to transform and adapt WRTC to a new norm was greatly assisted by the infrastructure readiness. All of these factors contributed greatly to a successful arrangement with zero to minimal downtime where a workstation was set up in each personnel's home, running at full capacity. This transformation was done within one day of the notice and completed within hours of activation. Despite the successful move, few rooms for improvements such as redundancy of VPN use to access applications and limited access to some proprietary software can be enhanced in the future. WRTC is ready to be mobile and agile to support the drilling operations remotely either in the office or from home. The quick turnaround is a major indicator that WRTC infrastructure and personnel are ready and capable for remote operations without interruption.
