Authors:   Faculty of Islamic Economic and Business, Universitas Islam Negeri (UIN) Datokarama Palu, Musyahidah Siti
Published: August 2021

The objective of this study is to find out the impact of riba avoidance motivation and product knowledge towards decision to be Islamic banks customers. Previous studies found that Muslim societies chose Islamic banks because they are interest-free. However, other studies also found that most Islamic banks customers do not have sufficient knowledge about Islamic bank products. Using the quantitative method, this study surveyed the effect of riba avoidance and product knowledge towards intention becoming Islamic bank costumers. There were thirty respondents who were chosen accidentally. Questions were distributed manually to the Islamic banks' customers. Our study found that riba avoidance and product knowledge significantly affect the decision to become a customer of Islamic banks in Palu City. This is proven by the sig-F value of 0.000, which is smaller than Alpha 0.05. At the same time, partially, the motivation to riba avoidance and product knowledge has a significant effect on the decision to become a customer of Islamic banks. Our findings highlight that Islamic banks should focus on providing more free riba products to attract more Muslim customers. In addition, customers' knowledge of Islamic banks' products should also become the banks' focus for improvement.

Metastatic Carcinoid Tumor to the Heart, A Dreadful Complication of Neuroendocrine Tumors Yet Under Estimated: About an Observation
Authors:   Clinical cardiology department, Mohammed V University, Military training hospital of Mohamed V, Rabat - Morocco, Samih Amina
Published: August 2021

Cardiac metastases are uncommon in neuroendocrine tumors (NET). Features of patients with metastatic carcinoid tumor involving the heart have not been well described. Although carcinoid tumors have been described in almost every organ, few reported cases of confirmed cardiac involvement. The overall incidence of myocardial carcinoid metastases among patients with metastatic carcinoid disease is about 4%. There is limited knowledge on the prevalence, clinical presentation, and management of heart metastasis. The availability and increasing use of modern imaging techniques leads to more frequent discovery of rare metastatic sites. Our aim is to further clarify the clinical manifestations of heart metastasis, to increase the knowledge of rare localizations of NET metastasis and insist on the systematic screening of metastatic carcinoid heart disease as an integral part of the echocardiographic evaluation in patients with carcinoid syndrome. We report the case of a 67-year-old male with history of a low differentiated neuroendocrine tumor, presenting with palpitations and dyspnea and which investigations have led to diagnose myocardial metastasis signing the progression of the NETs.

Published: August 2021

Độ bão hòa nước (Sw) là thông số vỉa quan trọng cần xác định để xây dựng mô hình địa chất, mô hình khai thác và tính toán trữ lượng. Một số mô hình xác định thông số Swcho kết quả không phù hợp hoặc khác biệt rất lớn so với thông số Swixác định từ mẫu lõi. Mục tiêu của nghiên cứu nhằm xác định mô hình tính toán độ bão hòa nước tối ưu nhất cho các vỉa chứa tầng Miocene phía Đông Bắc bể trầm tích Cửu Long, Việt Nam. Các tài liệu giếng khoan được sử dụng cho các mô hình gồm tài liệu địa vật lý giếng khoan (wireline logging) được kết hợp với tài liệu địa chất, mẫu lõi để hiệu chỉnh kết quả tính hàm lượng sét, độ rỗng và cuối cùng là độ bão hòa nước áp dụng cho cùng các thông số đầu vào liên quan như mật độ xương đá, mật độ dung dịch khoan, điện trở vỉa sét, điện trở dung dịch… cho các mô hình. Tầng chứa Miocene gồm các tập cát kết xen kẹp với các vỉa sét (shale). Bản chất của các tập sét này là kết quả lắng đọng của khoáng vật sét (clay) và sét bột (silt) trong môi trường năng lượng thấp. Khoáng vật sét là thành phần chủ yếu với kích thước hạt rất nhỏ nên sức căng bề mặt lớn, có khả năng bắt giữ các phân tử nước trên bề mặt (water-bound) chứa các cation. Như vậy, độ dẫn điện hay điện trở suất sẽ được đóng góp chủ yếu bởi 2 thành phần là điện trở suất của nước vỉa (Rw) và điện trở suất của nước trên bề mặt sét (Rwb). Kết quả tính toán độ bão hòa nước tại tầng Miocene cho thấy độ bão hòa nước tính bằng mô hình Dual-water có giá trị tiệm cận nhất với giá trị độ bão hòa nước ban đầu trong vỉa (Swi) so với kết quả của các mô hình Simandoux, Indonesia và mô hình Archie. Từ cách tiếp cận trên, kết quả của nghiên cứu này có thể áp dụng cho minh giải tầng chứa Miocene ở phía Đông Bắc bể Cửu Long, Việt Nam.

Occupational Performance Limitations After Concussion in College Students
Authors: Acord-Vira Amanda , Davis Diana , Lilly Christa
Published: August 2021

Importance: Occupational performance limitations (OPLs) are poorly understood sequelae of concussion. This study aimed to establish the need for occupational therapy services for people who have sustained a concussion and to support the profession’s role in facilitating occupational performance for college students experiencing signs and symptoms after concussion.

Objective: To describe the types and frequency of, and assess risk factors for, OPLs in college students after concussion.

Design: Cross-sectional descriptive study.

Setting: Web-based survey on Qualtrics.

Participants: A total of 220 participants completed the survey; of those, 52 (23.6%) self-identified as having sustained a concussion and were further asked about OPLs after the concussion.

Results: Eighty-nine percent (n = 46) of the participants reported an OPL in at least one area, and higher OPL scores were associated with the number of concussion symptoms (r = .34, p = .02) and increased recovery time (≥3 days vs. <3 days, p = .006).

Conclusions and Relevance: College students reporting concussions with more symptoms that persisted for longer periods were more likely to experience occupational performance loss. Frequent OPLs were reported in occupations associated with the participants’ primary role of student. These results indicate a unique need for occupational therapy intervention with students to facilitate their continued success in academic pursuits.

What This Article Adds: People who have sustained a concussion experience OPLs. Occupational therapy has a role in facilitating a return to occupational performance during recovery, especially in helping college students with concussion return to the classroom.
Receiving Recognition: A Case for Occupational Therapy Practitioners as Mental and Behavioral Health Providers
Authors: Wilburn Victoria G. , Hoss Alia , Pudeler Meghan , Beukema Emily , Rothenbuhler Candice , Stoll Hannah B.
Published: August 2021

Importance: An analysis by the Substance Abuse and Mental Health Services Administration (SAMHSA; 2015a) found that an additional 10,000 mental health care providers will be needed by 2025 to meet the expected growth in demand for treatment of people with mental illness, substance use disorder, or both. Despite being the largest payer of mental health services in the United States, the Medicaid program has extremely low numbers of mental health providers (Frank et al., 2003).

Objective: This Health Policy Perspectives column is a collaboration among academics, clinicians, and students in the fields of occupational therapy and law in an effort to advance state occupational therapy associations’ efforts to gain formal recognition of occupational therapy practitioners as Qualified Mental Health Providers (QMHPs) and/or Qualified Behavioral Health Providers (QBHPs).

Conclusion: Coordination among states to identify barriers and opportunities in this important advocacy effort are needed for continued successful inclusion of occupational therapy practitioners as QMHPs, QBHPs, or both.

What This Article Adds: This column will assist other states in their efforts by providing legislation, strategic advocacy examples, and a course of action.

Published: August 2021

Unpaid caregivers are often expected to help family members or friends overcome activity limitations and participation restrictions to successfully age in place. Caregivers assume multiple responsibilities, such as managing their own physical and psychosocial needs and navigating a complex health care system, and many feel ill equipped to fulfill the necessary health care responsibilities for their care recipients. Underprepared caregivers may cause poor outcomes for care recipients. Federal and state policy proposals call attention to the need to better support caregivers, especially as their numbers increase. Occupational therapy practitioners are well positioned to effectively engage caregivers as they navigate the health care system. The occupational therapy process looks broadly at the functional abilities, environmental contexts, and occupational demands that play a pivotal role in successful aging in place for clients and better outcomes for their caregivers. Now is the time to define occupational therapy’s distinct value to this area.

The aim of this study is to figure out the meanings of weighted beta index in bank sector and beta determinants of Vietcombank -VCB during pre-low (L) inflation period 2011-2016. In reality Vietcombank has gained many achievements but also there are certain weaknesses. Hung and Liu (2005) tested the volatility of airline betas in the capital asset pricing and three-factor pricing models, as well as exploring the potential factors affecting their values. While Fama and Frech (2004) suggest to add firm size into traditional formula of beta CAPM. The study results tell us that Market risk can increased and This may be caused by the increase in lending rate and decrease in both CPI and G (from our regression OLS). Therefore, governmental agencies need to reduce lending rate and increase GDP growth and not decreasing much CPI.
A Flexible Software/Hardware Adaptive Network for Embedded Distributed Architectures
Authors: Azar Celine
Published: August 2021

Embedded platforms are projected to integrate hundreds of cores in the near future, and expanding the interconnection network remains a key challenge. We propose SNet, a new Scalable NETwork paradigm that extends the NoCs area to include a software/hardware dynamic routing mechanism. To design routing pathways among communicating processes, it uses a distributed, adaptive, non-supervised routing method based on the ACO algorithm (Ant Colony Optimization). A small footprint hardware unit called DMC speeds up data transfer (Direct Management of Communications). SNet has the benefit of being extremely versatile, allowing for the creation of a broad range of routing topologies to meet the needs of various applications. We provide the DMC module in this work and assess SNet performance by executing a large number of test cases.
Predictive Model for Maize Stem Borers’ Classification in Precision Farming
Authors: Chukwunazo Ezeofor , Kenneth Akpado , Afamefuna Ulasi
Published: August 2021

This paper presents Predictive Model for Stem Borers’ classification in Precision Farming. The recent announcement of the aggressive attack of stem borers (Spodoptera species) to maize crops in Africa is alarming. These species migrate in large numbers and feed on maize leaf, stem, and ear of corn. The male of these species are the target because after mating with their female counterpart, thousands of eggs are laid which produces larvae that create the havoc. Currently, Nigerian farmers find it difficult to distinguish between these targeted species (Fall Armyworm-FAW, African Armyworm-AAW and Egyptian cotton leaf worm-ECLW only) because they look alike in appearance. For these reasons, the network model that would predict the presence of these species in the maize farm to farmers is proposed. The maize species were captured using delta pheromone traps and laboratory breeding for each category. The captured images were pre-processed and stored in an online Google drive image dataset folder created. The convolutional neural network (CNN) model for classifying these targeted maize moths was designed from the scratch. The Google Colab platform with Python libraries was used to train the model called MothNet. The images of the FAW, AAW, and ECLW were inputted to the designed MothNet model during learning process. Dropout and data augmentation were added to the architecture of the model for an efficient prediction. After training the MothNet model, the validation accuracy achieved was 90.37% with validation loss of 24.72%, and training accuracy 90.8% with loss of 23.25%, and the training occurred within 5minutes 33seconds. Due to the small amount of images gathered (1674), the model prediction on each image was of low confident. Because of this, transfer learning was deployed and Resnet 50 pretrained model selected and modified. The modified ResNet-50 model was fine-tuned and tested. The model validation accuracy achieved was 99.21%, loss of 3.79%, and training accuracy of 99.75% with loss of 2.55% within 10mins 5 seconds. Hence, MothNet model can be improved on by gathering more images and retraining the system for optimum performance while modified ResNet 50 is recommended to be integrated in Internet of Things device for maize moths’ classification on-site.

Authors: Chelbi Slaheddine , Moussi Riadh
Published: August 2021

In Wireless Sensors Networks (WSN) based application, a large number of sensor devices must be deployed. Energy efficiency and network lifetime are the two most challenging issues in WSN. As a consequence, the main goal is to reduce the overall energy consumption using clustering protocols which have to ensure reliability and connectivity in large-scale WSN. This work presents a new clustering and routing algorithm based on the properties of the sensor networks. The main goal of this work is to extend the network lifetime via charge equilibration in the WSN. According to many errors with sensing devices and to have greater data accuracy, we use a quorum mechanism. The proposed algorithms are evaluated widely and the results are compared with related works. The experimental results show that the proposed algorithm provides an effective improvement in terms of energy consumption, data accuracy and network lifetime.

Authors: Kabbur Mahabaleshwar , R Anand , Kumar V Arul
Published: August 2021

Vehicular Ad-hoc network (VANET) is one of the emerging technologies for research community to get various research challenges to construct secured framework for autonomous vehicular communication. The prime concern of this technology is to provide efficient data communication among registered vehicle nodes. The several research ideas are implemented practically to improve overall communication in VANETs by considering security and privacy as major aspects of VANETs. Several mechanisms have been implemented using cryptography algorithms and methodologies. However, these mechanisms provide a solution only for some restricted environments and to limited security threats. Hence, the proposed novel mechanism has been introduced, implemented and tested using key management technique. It provides secured network environment for VANET and its components. Later, this mechanism provides security for data packets of emergency messages using cryptography mechanism. Hence, the proposed novel mechanism is named Group Key Management & Cryptography Schemes (GKMC). The experimental analysis shows significant improvements in the network performance to provide security and privacy for emergency messages. This GKMC mechanism will help the VANET user’s to perform secured emergency message communication in network environment.

Published: August 2021

DDoS has a variety of types of mixed attacks. Botnet attackers can chain different types of DDoS attacks to confuse cybersecurity defenders. In this article, the attack type can be represented as the state of the model. Considering the attack type, we use this model to calculate the final attack probability. The final attack probability is then converted into one prediction vector, and the incoming attacks can be detected early before IDS issues an alert. The experiment results have shown that the prediction model that can make multi-vector DDoS detection and analysis easier.

Este artigo tem por objetivo discutir elementos que permitem a vivência do saber múltiplos e divisores na escola. Utilizamos as noções de habitat, nicho e praxeologia da Teoria Antropológica do Didático, desenvolvida por Chevallard (1998) e seus colaboradores. O percurso metodológico se sustenta numa abordagem qualitativa, composta pela análise dos documentos referenciais curriculares: Pernambuco (2012a, 2012b, 2013); Recife (2015) e do livro didático de Matemática do 6º ano adota pela escola. O estudo foi desenvolvido em duas etapas. A primeira composta pela análise dos referenciais curriculares, enquanto que a segunda é dedicada a analisar a proposta do livro didático. Os resultados revelam: aproximações entre Pernambuco (2013) e Recife (2015); existência de dois habitats com diferentes funcionalidades, para o citado saber; aproximações entre o livro e os referenciais. Por fim, verificarmos que o estudo dos critérios de divisibilidade é uma forte razão de ser do estudo de múltiplos e divisores.
CULTURA ORGANIZACIONAL ESCOLAR E A POLÍTICA DE GESTÃO DEMOCRÁTICA DA EDUCAÇÃO
Authors: Moura Jamerson Kemps Gusmão
Published: August 2021

Refletimos nesse artigo sobre a relação que se estabelece entre cultura organizacional escolar e a apropriação e viabilização de políticas públicas. Concentramos nossa análise sobre as principais mudanças pelas quais passaram os campos educacionais de Pernambuco, no Brasil, e Coimbra, Portugal, questionando: a cultura organizacional sedimentada nas escolas desses dois campos poderia constituir um fator de resistência ao processo de implementação de políticas públicas? Dentre as conclusões, destacamos que a implementação de políticas públicas tem a sua viabilização diretamente ligada às formas como ela é apropriada e dinamizada em cada cultura organizacional escolar; assim, em Estados forjados por práticas autoritárias, o recente processo de redemocratização não conseguiu reverberar o suficiente na sociedade, fazendo a maioria dos atores que reproduzem as determinações estatais não serem capazes de implementar uma gestão democrática da educação.

Qualidade de Serviços: Uma análise comparativa entre SERVQUAL e SERVPERF
Authors: Souto Christiane De Melo Rêgo , Correia-Neto Jorge Da Silva
Published: August 2021

Desde os anos 1980 discute-se como mensurar a qualidade dos serviços prestados, especialmente por que cada vez mais tem-se algum tipo de serviço associado aos produtos comercializados. Entretanto, a escala proposta por Parasuraman, Zeithaml e Berry, nomeada SERVQUAL, não é uma unanimidade até hoje. Além das críticas quanto a diversos aspectos, inclusive estatísticos, a escala SERVPERF obtém resultados iguais ou melhores do que sua antecessora, mas mesmo assim também não é uma unanimidade. Em síntese, a SERVQUAL apresenta 22 variáveis dispostas nas seguintes dimensões: tangíveis, confiabilidade, receptividade, segurança e empatia. A SERVPERF utiliza as mesmas variáveis e dimensões, contudo, ao invés de analisar o gap existente entre as expectativas e a performance do serviço executado, capta a percepção do cliente apenas após o consumo do serviço. O presente ensaio, a partir da literatura da área de marketing de serviços, buscou apontar as vantagens e desvantagens de cada uma dessas escalas e assim propor à comunidade científica um novo debate, mais fundamentado, sobre as referidas escalas. O estudo demonstrou o crescimento do interesse no tema e como contribuição apontou as principais vantagens e desvantagens de cada uma dessas escalas.

Authors:   , Estrice Milton Solomon
Published: August 2021

Renewable energy in particular solar energy is a viable option to meet the increasing energy demand for the modern world. The Solar resource in South Africa is among the highest in the world. With the progression of modern society, both energy demands and energy prices are increasing, which has welcomed the introduction of renewable energy resources as an alternative. However, solar radiation varies over the complete day sometimes over the season, and sometimes over the complete year. Further, the power demand is highly variable in nature. Hence, the generated power should match the customer demands over the period of twenty-four hours, and further, it should be economical for customers and electrical utilities. Hence, this study will focus on integrating PV plants with thermal plants to meet the rising customer power demand. The integration of PV with thermal power plants will bring some new challenges in the domain of power system operation & control which is the frequency of the power system should be restricted to well-defined values. Hence, suitable control strategies are to be developed for the successful and smooth operation of the power system. In this research work, an attempt is made to investigate an interlinked system comprising of a thermal and a PV generation system. The control strategies based on PID controllers and their gains tuned through effective tuning techniques are presented. In addition, the concept of fuzzy logic is used to address the problem of frequency managing of PV-Thermal via effectively designing fuzzy proportional, fuzzy integral, and fuzzy PI built control strategies to ensure the frequency regulation of the energy system. The obtained results are shown via a graphical approach, and the best control design is explore and suggested for the considered system. In addition, the scope for further improvement and possible direction areas are also explored and listed in this report.

Trong quá trình chuyển đổi cơ cấu cây trồng, cây gai nổi lên như một đối tượng sáng giá để nhiều địa phương lựa chọn thay cho các cây trồng khác kém hiệu quả. Diện tích cây gai xanh lấy sợi của Việt Nam đã trên 1000 ha (2018). Sau khi lấy vỏ làm sợi, một lượng lớn bã thải thân lá cây gai được thải ra ngoài môi trường. Các chất thải hữu cơ sau một thời gian để ngoài tự nhiên nó bị phân hủy sinh học gây ra mùi hôi, thối môi trường xung quanh. Việc tạo ra một chế phẩm vi sinh chuyên để xử lý bã thải cây gai làm sạch môi trường là cần thiết. Để giải quyết vấn đề đó, đề tài đã nghiên cứu thu thập, phân lập và tuyển chọn được những chủng vi sinh vật có khả năng phân giải xenluloza và lignin thành phần chính trong thân lá cây gai. Kết quả đã chọn được 4 chủng vi sinh vật có hoạt tính phân giải xenluloza và lignin cao để sản xuất chế phẩm sinh học phân giải bã thải cây gai xanh và có khả năng tổ hợp tốt là các chủng xạ khuẩn RR04, BG05, BG08, vi khuẩn RR05. Nghiên cứu cũng đã lựa chọn được môi trường lên men thích hợp nhất là MT2 để các chủng vi sinh vật có được hoạt tính sinh học xử lý bã thải cây gai tốt nhất.

: mundo moderno onde vivemos atualmente exige que aprendamos uma série de habilidades, entre elas a leitura e escrita, que são importantes para que novas descobertas sejam alcançadas. Porém nem todos os indivíduos conseguem alcançar esse aprendizado na fase escolar, devido a fatores variados que impedem essa aprendizagem. Entre esses fatores existe um distúrbio chamado dislexia, que impede a natural aprendizagem da leitura e escrita, que se apresenta de forma mais clara nos primeiros anos do ensino fundamental. Logo a uma necessidade do educador conhecer os sintomas da dislexia para que seja possível viabilizar um plano de ação para minimizar os problemas de aprendizagem provocado pela dislexia, diante desse exposto esse trabalho de pesquisa se justifica. O presente trabalho tem o objetivo de pesquisar as dificuldades de aprendizagem de leitura e escrita provocadas pela dislexia, investigando quais as ações que podem ser tomadas pelos educadores em sala de aula para diagnosticar e tratar a dislexia. Para atingir os objetivos dessa pesquisa esse trabalho conta com uma revisão bibliográfica baseado em ideias de autores que já se debruçaram sobre o tema da dislexia. Nesse contexto o presente trabalho se desenvolve no sentido de definir o que é dislexia, apresentando as suas características e sintomas, assim como seu tratamento e o papel do educador em sala de aula frente a esse problema de aprendizagem.

Abstract. We currently have a limited understanding of the spatial and temporal variability in vertically stratified atmospheric layers over Namibia and the southeast Atlantic (SEA) Ocean. Stratified layers are relevant to the transport and dilution of local and long-range transported atmospheric constituents. This study used eleven years of global positioning system radio occultation (GPS-RO) signal refractivity data (2007–2017) over Namibia and the adjacent ocean surfaces, and three years of radiosonde data from Walvis Bay, Namibia, to study the character and variability in stratified layers. From the GPS-RO data and up to a height of 10 km, we studied the spatial and temporal variability in the point of minimum gradient in refractivity, and the temperature inversion height, depth and strength. We also present the temporal variability of temperature inversions and the boundary layer height (BLH) from radiosondes. The BLH was estimated by the parcel method, the top of a surface-based inversion, the top of a stable layer identified by the bulk Richardson number (RN), and the point of minimum gradient in the refractivity (for comparison with GPS-RO data). A comparison between co-located GPS-RO to radiosonde temperature profiles found good agreement between the two, and an average underestimation of GPS-RO to radiosonde temperatures of −0.45 ± 1.25 °C, with smaller differences further from the surface and with decreasing atmospheric moisture content. The minimum gradient (MG) of refractivity, calculated from these two datasets were generally in good agreement (230 ± 180 m), with an exeption of a few cases when differences exceeded 1000 m. The surface of MG across the region of interest was largely affected by macroscale circulation and changes in atmospheric moisture and cloud, and was not consistent with BLH(RN). We found correlations in the character of low-level inversions with macroscale circulation, radiation interactions with the surface, cloud cover over the ocean and the seasonal maximum in biomass burning over southern Africa. Radiative cooling on diurnal scales also affected elevated inversions between 2.5 and 10 km, with more co-occurring inversions observed at night and in the morning. Elevated inversions formed most frequently over the subcontinent and under subsidence by high-pressure systems in the colder months. Despite this macroscale influence peaking in the winter, the springtime inversions, like those at low levels, were strongest.

Abstract. Despite the numerous studies investigating haze formation mechanism in China, it is still puzzling that intensive haze episodes could form within hours directly following relatively clean periods. Haze has been suggested to be initiated by the variation of meteorological parameters and then to be substantially enhanced by aerosol–radiation–boundary layer feedback. However, knowledge on the detailed chemical processes and the driving factors for extensive aerosol mass accumulation during the feedback is still scarce. Here, the dependency of the aerosol number size distribution, mass concentration and chemical composition on the daytime mixing layer height (MLH) in urban Beijing is investigated. The size distribution and chemical composition-resolved dry aerosol light extinction is also explored. The results indicate that the aerosol mass concentration and fraction of nitrate increased dramatically when the MLH decreased from high to low conditions, corresponding to relatively clean and polluted conditions, respectively. Particles having their dry diameters in the size of ∼400–700 nm, and especially particle-phase ammonium nitrate and liquid water, contributed greatly to visibility degradation during the winter haze periods. The dependency of aerosol composition on the MLH revealed that ammonium nitrate and aerosol water content increased the most during low MLH conditions, which may have further triggered enhanced formation of sulfate and organic aerosol via heterogeneous reactions. As a result, more sulfate, nitrate and water-soluble organics were formed, leading to an enhanced water uptake ability and increased light extinction by the aerosols. The results of this study contribute towards a more detailed understanding of the aerosol–chemistry–radiation–boundary layer feedback that is likely to be
responsible for explosive aerosol mass growth events in urban Beijing.

Abstract. In a companion paper (Horváth et al., 2021), we
introduced a new technique to estimate volcanic eruption column height from
extremely oblique near-limb geostationary views. The current paper
demonstrates and validates the technique in a number of recent eruptions,
ranging from ones with weak columnar plumes to subplinian events with
massive umbrella clouds and overshooting tops that penetrate the
stratosphere. Due to its purely geometric nature, the new method is shown to
be unaffected by the limitations of the traditional brightness temperature
method, such as height underestimation in subpixel and semitransparent
plumes, ambiguous solutions near the tropopause temperature inversion, or
the lack of solutions in undercooled plumes. The side view height estimates
were in good agreement with plume heights derived from ground-based video
and satellite stereo observations, suggesting they can be a useful
complement to established techniques.
