Authors: C Venkata Sudhakar , G Umamaheswara Reddy
Published: August 2023

Limestone mining is a significant economic activity in India, accounting for around 10% of the GDP however, it has certain negative environmental consequences. The objective of this study is to determine the spatial distribution area of captive limestone mines using remote sensing datasets, spectral index, and machine learning algorithms and compare their area estimation with industrial field survey reports for the financial year 2019. The study area includes a limestone resource area of 2226.16 ha with an excavation area of 487.10 ha in 2019. In the present research, we used a high-resolution Sentinel-2A satellite dataset to map and compute the active mining area by implementing the Normalised Vegetation Index (NDVI), Iterative Self-Organizing Data Analysis Technique (ISODATA), K-Nearest Neighbours (KNN), and Random Forest (RF) algorithms in the QGIS 3.18 software tool. The RF classifier estimated a limestone mine area of 379.57 ha with user accuracy (UA) of 97.25% and producer accuracy (PA) of 99.18% with a kappa coefficient value of 0.957. The mine area was estimated at 417.47 ha with a UA of 98.99% and PA of 99.10% and kappa value of 0.947 of the KNN method, The NDVI method estimated 469.92 ha with a UA of 93.63% and PA of 92.04% and kappa value 0.685. This research confirmed that the RF classifier well performed in classification with overall accuracy (OA) of 95.79% to KNN (OA of 94.78%), NDVI (OA of 79.84%) classifiers, and ISODATA poor in classification with OA of 64.16%. This research assists limestone mine owners and environmental engineers in making environmentally sustainable decisions, eco-friendly mine design, and monitoring.

Published: August 2023

The sillenite-structured bismuth titanate (Bi12TiO20) is thought to be a viable photocatalyst for environmental remediation. However, the performance of Bi12TiO20 as a photocatalyst is severely constrained by its limited range of light sensitivity and the rapid photoinduced electron-hole pair recombination. A practical and effective way to overcome these limitations is to combine Bi12TiO20 with adequate photocatalysts to create heterojunctions. Here, a one-step solvothermal technique is used to synthesize Bi12TiO20/Bi4Ti3O12 heterojunction (BTO). The electric field that exists between B12TiO20, Bi4Ti3O12 and the closed interfacial contacts had a synergistic effect on the constructed composites, which resulted in high charge transfer abilities. Therefore, the BTO heterojunction demonstrated increased photocatalytic efficacy in the presence of ultraviolet irradiation. The MO removal efficiency of optimal BTO was 97.15%, significantly higher than that of pure Bi2O3 (46.9%). Furthermore, the cycling experiment demonstrated that the BTO heterojunction is stable and reusable. The probable mechanism of photocatalytic MO oxidation over BTO heterojunction was studied by various scavengers. The •OH radicals and holes played essential roles in BTO system of photocatalytic oxidation process.

BACKGROUND: Mild cognitive impairment (MCI) is a mild memory or cognitive impairment. OBJECTIVE: To explore the relationship between serum klotho (K1) protein and insulin-like growth factor-1 and mild cognitive impairment in the elderly in order to provide accurate and appropriate indicators for clinical diagnosis and treatment of MCI. METHODS: This randomized stratified study adopted a multistage cluster sampling method. 161 elderly patients with mild cognitive impairment were included as the MCI group, and 161 healthy people matched with the MCI group in gender, age and education were selected as the control group. RESULTS: The levels of serum K1 protein and insulin-like growth factor-1 in the MCI group were lower than those in the control group (P< 0.05). Both IGF-1 and K1 had predictive value for MCI (P< 0.05). The area under the curve (AUC) of IGF-1 for predicting MCI was 0.859 (95% CI: 0.790∼0.929), and the AUC of K1 for predicting MCI was 0.793 (95% CI: 0.694∼0.892). The value of joint prediction of the two indicators was the highest, with an AUC of 0.939 (95% CI: 0.896–0.993). CONCLUSION: High serum K1 and insulin-like growth factor-1 are the protective factors of cognitive impairment in MCI patients. Both IGF-1 and serum K1 proteins have predictive value for MCI, and the combination of the two indicators has the highest predictive value.

Published: August 2023

Vários foram os homens que entre nós se esforçaram para abrir caminho nessa luta ingrata, travada até hoje, contra o grande mal. Alguns procuraram acertar empregando uma ou outra das armas usuais. Mas luta contra o câncer, na verdadeira acepção da palavra, significa reunião de todos os elementos de ataque, articulados em ação conjunta, num objetivo médico-social de maior alcance, visando a defesa das massas. E a conjugação desses elementos — microscópio, bisturi, raios X, radium e eletrocirurgia, ao lado da propaganda — só foram congregados, nesta cidade, pelos fundadores do antigo Centro de Cancerologia, que era um pequeno pavilhão construído em 1936, ao lado do antigo Hospital Estácio de Sá. Foi oficializado em janeiro de 1937, com o nome de Centro de Cancerologia, por decreto do Presidente Vargas, com exposição de motivos que elaboramos. Fomos nomeado diretor em dezembro de 1937; a inauguração oficial realizada em maio de 1938; os primeiros doentes foram internados em 28 de setembro de 1938.
Tumores do Aparelho Digestivo e Alcalose Extra Celular
Authors: Vale José Carlos do
Published: August 2023

Foi estudada a composição ácido-básica extracelular de 20 pacientes portadores de neoplasia do aparelho digestivo, com um total de 37 determinações. Nove pacientes foram estudados no pré e pós-operatório, 4 no pós-operatório tardio e 7 considerados posteriormente inoperáveis. A alcalose respiratória, mista e metabólica foram os distúrbios mais encontrados. Após revisão histórica e dos conceitos atuais de equilíbrio ácido-básico, o método utilizado é descrito com minúcias. São apresentados casos clínicos que ilustram o aparecimento da alcalose extracelular e seu tratamento. A fismpatologia desta alcalose é discutida com pormenores. Nossos achados parecem confirmar a hipótese já descrita em outras circunstâncias clínicas: a depleção de potássio corporal acarreta acidose intracelular, que estimula os centros respiratórios produzindo hiperventilação e conseqüente alcalose respiratória. A correção obtida por nós da alcalose respiratória e mista com soluções de cloreto de potássio parece corroborar esta teoria. Deve-se ter o cuidado em não interpretar hiperventilação, acidúria e reserva alcalina baixa, em doentes com neoplasia do aparelho digestivo, como senão acidose metabólica. Lembrar que a alcalose respiratória pode apresentar idênticas manifestações e é muito mais freqüente. Os erros desta interpretação podem conduzir a uma terapêutica errônea com soluções alcalinizantes. Se o paciente for para a cirurgia com grande déficit de potássio e o meio intracelular acidificado, o stress cirúrgico agravará a alcalose. A correção, pelo menos em parte, desta depleção e da composição corporal alterada é de fundamental importância para o bom êxito da cirurgia.

O autor faz uma revisão crítica sôbre a ocorrência de neoplasias malignas nas regiões tropicais, comparando com os dados do seu material, obtidos na cidade tropical do Recife (8° 3’ S e 34° 51 0), Pernambuco, Brasil. Chegam às seguintes conclusões: 1) As neoplasias malignas são freqüentes nos Trópicos e regiões sub-desenvolvidas do mundo. 2) Algumas formas de neoplasia maligna são mais freqüentes nas regiões Tropicais de que nas de clima temperado. Isso ocorre principalmente com os carcinomas epidermóides, particularmente os do colo uterino, bôca, pênis e os carcinomas epidermóide e baso-celular da pele. 3) Na África e Ásia Tropical é alta a incidência de carcinoma primitivo do fígado, o que não parece ocorrer na América Tropical. 4) Na África Tropical tem sido relatada uma alta freqüência de linfomas malignos, particularmente em crianças. Para o autor essa é uma questão provávelmente sujeita à revisão. 5) O cariocarcinoma e o carcinoma do naso-faringe têm sido encontrados com alta freqüência na Ásia, particularmente na Ásia Tropical. 6) Chamam a atenção para o fato de que a maioria dos cânceres prevalentes nos Trópicos, são de fácil diagnóstico, fácil prevenção e fácil cura (dentro de certos limites de avanço da doença). São formas de câncer que tendem a diminuir ou desaparecer nos países desenvolvidos. 7) A persistência dessas formas, nos Trópicos, deve-se a situação econômico-social precária prevalente nessas áreas.

Baseando-se em certas relações existentes entre a etiologia do câncer e a do diabetes, os autores procuram combinar de uma maneira adequada a ação benéfica dos fosfolipídeos com a da insulina. Os resultados experimentais foram surpreendentes, pois foi conseguida uma inibição total do crescimento do sarcoma de Yoshida em nada menos que 60% dos animais tratados, enquanto nos 40% restantes foi observado um retardamento do crescimento do tumor de 50% em relação ao controle. Aloxana, associada aos fosfolipídeos demonstrou, embora em menor escala, também um efeito favorável.

La detección precoz del Autismo es un desafío en Chile y América Latina. Las evaluaciones gold-stan- dard son de alto costo y difícil disponibilidad. El Examen de Estado Mental para Autismo (AMSE) es un instrumento breve, estructurado, observacional, para uso clínico con promisorios resultados. Objetivo: Adaptar y validar AMSE en muestra de niños, niñas y adolescentes (NNA) hispanohablantes con riesgo de Espectro Autista (EA) utilizando como comparación ADOS-2. Sujetos y Métodos: NNA de 15m-17a, consultantes por problemas de lenguaje, comunicación y/o sospecha de EA. AMSE fue administrado durante evaluación clínica. ADOS-2 fue administrado por evaluadores independientes, ciegos, determinando categorías: No Espectro Autista (NoEA), Espectro Autista (EA) o Autismo (AUT). Se evaluó características psicométricas de AMSE y usando curva ROC se calculó punto de corte, identificando sensibilidad, especificidad, valor predictivo positivo y negativo. Resultados: Participaron 64 NNA, 56 varones (87,5%), con edad promedio 6,6 años (DE:3,6). Se distribuyeron según ADOS-2 en NoEA:12 (18,8%), EA:19 (29,7%), AUT:33 (51,6%). Los puntajes AMSE difirieron significativamente entre las tres categorías (p < 0,0001). AMSE tuvo consistencia interna moderada, con Alfa de Cronbach 0,61. Punto de corte ≥ 6 puntos (sensibilidad 0,79 especificidad 0,92, AUC: 0,91). Un segundo análisis según nivel de lenguaje sugiere mayor precisión diagnóstica de AMSE para el grupo con menor desarrollo de lenguaje, manteniéndose punto de corte óptimo de ≥ 6 puntos. Conclusión: AMSE muestra adecuadas propiedades psicométricas, buena capacidad y precisión para respaldar el diagnóstico de EA. Su brevedad, bajo costo y fácil integración a la práctica clínica, lo hacen una alternativa de gran potencial para el reconocimiento y derivación oportunos de NNA en EA.

Huney guava (Syzygium aqueum) is a potential agricultural product of Secanggang District, Langkat Regency, which is generally sold in fresh fruits. The production of Guava in this area reaches 150 kg per farmer, with 25-30 kg of them remain unsold. This community service aims to disseminate knowledge and technology to farmers about processing honey guava fruit into chips with the trade name "KeJaM". This activity is expected to be a solution for farmers in processing unsold products into new products that can increase economic value, as well as reduce agricultural waste. In this activity, the community service activities team also provided honey herb processing equipment, namely a vacuum fryer and spinner, so that the honey guava chips produced still have the characteristic honey guava taste. KeJaM is a healthy snack which is expected to attract the interest of public in order to improve the economy and welfare of farmers.
ЗМІНИ ХІМІЧНОГО СКЛАДУ ВОДИ У ГІДРОЕКОСИСТЕМАХ РІЗНОГО ТИПУ
Authors: Ковальова Ілона Василівна
Published: August 2023

Хімічний склад гідроекосистем постійно змінюються внаслідок зовнішніх (антропогенез, кліматичні зміни, військові дії) та внутрішніх (внутрішньоводоймні процеси) впливів. Найбільш поширеними забруднювачами, що надходять до водойм з поверхневим стоком із забудованих і промислових територій, з атмосферними опадами, внаслідок вивітрювання, використання добрив та синтетичних мийних засобів, захоронення відходів, є сульфати, хлориди та фосфати. Мета дослідження – визначення зміни хімічного складу води у гідроекосистемах різного типу (річка, водосховище, кар’єр та озеро). У статті досліджено сезонні зміни вмісту сульфатів, хлоридів та фосфатів у гідроекосистемах різного типу та наведено основні джерела їхнього надходження. Наведено вміст сульфатів у воді р. Стубелка (38,4–77,8 мг/дм3), Хрінницькому водосховищі (40,3–71,1 мг/дм3), оз. Засвітське 40,3–67,2 мг/дм3) та Морозівського кар’єру (50,0–69,2 мг/дм3). Крім антропогенних чинників, сульфати надходять у водойми внаслідок відмирання біоти та процесів окиснення речовин рослинного та тваринного походження. Зафіксовано зміни концентрації хлоридів у воді р. Стубелка (14,9–28,4 мг/дм3), Хрінницького водосховища (14,9–20,6 мг/дм3), оз. Засвітське (3,54– 21,1 мг/дм3), Морозівського кар’єру (7,09–39,0 мг/дм3). Найвищі концентрації фосфатів виявлено у воді р. Стубелка (0,058–0,117 мгP/дм3) та Хрінницького водосховища (0,030–0,094 мгP/ дм3, а найнижчі – у воді оз. Засвітське (0,007–0,024 мгP/дм3) та Морозівського кар’єру (0,005–0,022 мгP/дм3). Визначено, що вміст сульфатів, хлоридів та фосфатів у воді всіх водних об’єктів не перевищує допустимі значення впродовж усього періоду дослідження. Показано, що вміст досліджених сполук у водних об’єктах змінюється таким чином: SO4 2¯ – кар’єр > озеро > річка > водосховище; Cl¯ – кар’єр > річка > водосховище > озеро; PO4 3¯ – річка > водосховище > кар’єр > озеро.

У статті досліджено основні еколого-економічні аспекти розвитку Прикарпатського регіону, визначено основні екологічні проблеми Львівщини та Івано-Франківщини та запропоновано можливі шляхи їх подолання. Наведено основні показники еколого-економічного розвитку областей Прикарпаття у Екологічному рейтингу регіонів України за 2022 рік. Зазначено, що Чернівецька область займає лідируючі позиції в екологічному рейтингу регіонів України протягом 2021–2022 років. Обґрунтовано, що оскільки екологічна ситуація в Україні в цілому, і в Прикарпатському регіоні зокрема, є особливо складною, забруднення навколишнього середовища, повітря, водоймищ і грантів наносить непоправну шкоду здоров’ю людей. Доведено, що взаємозв’язок між економікою та екологією стає все більш очевидним і вимагає комплексного підходу до розв’язання цієї проблеми. Обґрунтовано завдання, які потребують негайного вирішення для подолання наявних екологічних проблем в регіоні. Акцентовано увагу на доцільності використання відновлювальнних джерел енергії як важливого елемента еколого-економічного розвитку, що дозволить зменшити залежність від імпортованої нафти та газу, зменшити викиди парникових газів та забезпечити стійкий розвиток економіки Прикарпатського регіону. Наголошено, що окремим аспектом еколого-економічного розвитку є забезпечення екологічної безпеки та контроль за викидами забруднюючих речовин. В результаті проведенного наукового дослідження встановлено, що в майбутньому економічний розвиток Прикарпатського регіону повинен бути сталим, тобто повинен забезпечити належний рівень економічного зростання, не порушуючи екологічні рівноваги. Тому для цього необхідно розробляти ефективні плани розвитку, що передбачають захист довкілля та раціональне використання усіх наявних ресурсів.

Published: August 2023

The article examines the peculiarities of using digital marketing and artificial intelligence in the market of agricultural products. The cost of food products has increased significantly as a result of the destructive factors that have taken place in recent years. This led to a negative impact on the purchasing power of the population in many countries of the world. The influence of globalization and digitalization on the market of agricultural products is studied. The feasibility of developing modern marketing strategies for agricultural companies has been proven, which will allow identifying the target audience and building effective communications in the long term. The need to use digital marketing tools in connection with the reorientation of a significant number of the population to the digital environment is substantiated. For a successful marketing strategy, it is necessary to highlight the special characteristics of agricultural products that make a certain brand distinct for the target audience and encourage them to prefer these products. The peculiarities of artificial intelligence integration into the marketing strategies of agricultural companies in order to achieve optimal results are revealed. The necessity of using large amounts of information in the implementation of artificial intelligence algorithms, which allows to increase the level of conversion, has been established. In today's conditions of active development of artificial intelligence, farmers, agribusinesses and agricultural companies have new opportunities to make effective decisions regarding the promotion of their products, and at the same time they can do this with relatively little expenditure of monetary resources. The main ways of applying artificial intelligence in the digital environment for the implementation of agricultural companies marketing strategies are considered. The implementation of artificial intelligence in chatbots allows to increase the accuracy of answers to user requests and gives the impression of communication with real people. Artificial intelligence provides agricultural companies with the opportunity to analyze the development of relevant markets, predict changes in customer behavior and forecast future demand for products and services of the agro-industrial sector.

The article reveals the theoretical and practical aspects of conducting business in social networks. The distinctive features and capabilities of the most popular social networks: Instagram, Facebook, TikTok were studied and the peculiarities of conducting business in these popular social networks were studied. The study of the influence of social networks on the promotion and efficiency of business was conducted on the example of the flower market. In recent years, the flower business has experienced a decline, which was caused first by the crisis and then by the war in the country. Today, Instagram has become one of the best platforms for running a floristry business. This social network has provided many useful tools and advantages for the owners of this business: it allows you to sell online, present goods and services on the network, monitor detailed account statistics, as well as follow coverage and feedback. All this became possible thanks to the creation, adjustment and promotion of the company's business profile. A business profile on Instagram is a company or brand account filled with features, as well as effective tools for making sales, presenting goods and services online. A business page provides many opportunities that are not available to ordinary users: the ability to connect applications and add-ons for sales, convenient setting of targeting, advertising, as well as viewing statistics. A study of the impact of the business profile on the effectiveness of the advertising process was conducted. With the correct use of targeted advertising, you can significantly save time and budget and attract a target audience that will be interested in this product. The process of creating a business page on Instagram was considered and, as an example, a business page for a flower shop was developed, its settings and targeting were carried out. An ordinary page of a flower shop on the Instagram social network was taken as a basis. Next, a transition from a regular page to a business page was made. Creating a business profile on the most popular social networks such as Instagram and Facebook will allow companies to attract more and more new customers, increase their profits, and draw attention to their brand.

The article considers the definition of the concept of innovation and the factors affecting the need for innovation. It was noted that the successful implementation of innovations in the development of new goods and services and in production technologies is the key to maintaining a high level of economic performance of enterprises in the B2C and B2B markets. The development of innovative activity in Ukraine and the change in the indicator of innovative activity in the B2C and B2B markets were studied. It is highlighted that the focus on new technologies, marketing methods, trends and new services helps entrepreneurs to constantly attract customers, develop innovatively and increase profits. The article states that there is a need to apply not only product innovations, but also innovations aimed at elements of the marketing complex, the goals of marketing activities are defined: short-term and long-term. The process of planning a new product was studied and its stages were determined. The foreign experience of developing and introducing new products to the market was analyzed. Taking into account the foreign experience of implementing product innovations, it is recommended that at the stage of developing a marketing strategy, more attention should be paid precisely to the price expectations of consumers, since among the main factors of the success of enterprises in modern market conditions is leadership in terms of costs. The peculiarities of the implementation of product innovations of enterprises operating in the B2C and B2B markets are considered. It is noted that the approach to the development of a new product of companies operating both in the B2C and B2B markets requires detailed study, since according to statistics, almost 40% of unsuccessful innovative developments are observed in the B2C market and about 20% in the B2B market. Enterprises that work on the B2B market have certain features regarding the introduction of innovative products to this market. These companies must take into account the risks faced by the consumer organization. Product innovation is a decisive factor in the marketing activities of companies.

Mares y océanos sufren un grave problema de contaminación a causa de la presencia de residuos plásticos que afecta no solo a la biota marina, sino también a los seres humanos. A pesar de la abundante información sobre la presencia de plásticos en mares y océanos, aún se carece de conocimiento sólido sobre la cantidad de plásticos que ingresan al medio marino. Esta situación se agrava con respecto a los nano y microplásticos; dado que la mayor parte de las investigaciones se han enfocado a los macroplásticos y a regiones de fácil acceso como playas. Por otra parte, la carencia de una armonización o estandarización de metodologías, clasificaciones y una definición funcional de nano y microplásticos no permite la comparación de datos espaciales y temporales de la problemática entre la comunidad científica. El objetivo del presente trabajo es presentar la información actual sobre los nano y microplásticos: definiciones, fuentes, metodologías, ingestión, toxicidad, alteración de hábitat e introducción de especies.

This article presents the results of a study of a new grapevine variety called Hope, developed within the Breeding Program of the University of Arkansas, USA. The research was conducted at experimental plots of the All-Russian Research Institute of Viticulture and Winemaking – Branch of Federal State Budget Scientific Institution «FRARC». The Hope grapevine variety possesses several positive characteristics: it belongs to the seedless category of the second class, has dense flesh, and exhibits a complex and rich flavor and taste profile. The average weight of a cluster is 320 grams, while the average weight of a berry is 4.2 grams. The Hope variety has high yield potential, reaching up to 124 quintals per hectare. It shows vigorous vine growth and good resistance to diseases. Additionally, it has a good winter hardiness. Standard methodologies and vineyard cultivation techniques were used in the study. The vineyards where the research was conducted were non-irrigated and grafted, using the Oppenheim SO4 rootstock, with bilateral cordon training and a planting scheme 3×1.5 meters. The results indicated that the Hope variety has an early ripening period (requiring 118 days from bud break to full berry maturity). It has promising for use in winemaking and does not require yield regulation measures. Overall, the Hope grape variety is of interest for commercial cultivation in industrial vineyards. Its economically valuable qualities and attributes make it appealing for consumption in fresh form, wine production, and the production of dried products. It can also be included in the breeding programs of scientific institutions for further development and improvement of grape varieties.
A Cascaded and Adaptive Visual Predictive Control Approach for Real-Time Dynamic Visual Servoing

Published: August 2023

In the past two decades, Unmanned Aerial Vehicles (UAVs) have gained attention in applications such as industrial inspection, search and rescue, mapping, and environment monitoring. However, the autonomous navigation capability of UAVs is aggravated in GPS-deprived areas such as indoors. As a result, vision-based control and guidance methods are sought. In this paper, a vision-based target-tracking problem is formulated in the form of a cascaded adaptive nonlinear Model Predictive Control (MPC) strategy. The proposed algorithm takes the kinematics/dynamics of the system, as well as physical and image constraints into consideration. An Extended Kalman Filter (EKF) is designed to estimate uncertain and/or time-varying parameters of the model. The control space is first divided into low and high levels, and then, they are parameterised via orthonormal basis network functions, which makes the optimisation- based control scheme computationally less expensive, therefore suitable for real-time implementation. A 2-DoF model helicopter, with a coupled nonlinear pitch/yaw dynamics, equipped with a front-looking monocular camera, was utilised for hypothesis testing and evaluation via experiments. Simulated and experimental results show that the proposed method allows the model helicopter to servo toward the target efficiently in real-time while taking kinematic and dynamic constraints into account. The simulation and experimental results are in good agreement and promising.

Inverse kinematics (IK) of concentric tube continuum robots (CTRs) is associated with two main problems. First, the robot model (e.g., the relationship between the configuration space parameters and the robot end-effector) is not linear. Second, multiple solutions for the IK are available. This paper presents a general approach to solve the IK of CTRs in the presence of constrained environments. It is assumed that the distal tube of the CTR is inserted into a cavity while its proximal end is placed inside a tube resembling the vessel enabling the entry to the organ cavity. The robot-tissue interaction at the beginning of the organ-cavity imposed displacement and force constraints to the IK problem to secure a safe interaction between the robot and tissue. The IK in CTRs has been carried out by treating the problem as an optimization problem. To find the optimized IK of the CTR, the cost function is defined to be the minimization of input force into the body cavity and the occupied area by the robot shaft body. The optimization results show that CTRs can keep the safe force range in interaction with tissue for the specified trajectories of the distal tube. Various simulation scenarios are conducted to validate the approach. Using the IK obtained from the presented approach, the tracking accuracy is achieved as 0.01 mm which is acceptable for the application.
Dynamic phase measurement in shearography by clustering method and Fourier filtering

Quantitative phase extraction is a key step in optical measurement. While phase shifting technique is widely employed for static or semi-static phase measurement, it requires several images with known phase shifts at each deformed stage, thus is not suitable for dynamic phase measurement. Fourier transform offer a solution to extract phase information from a single fringe pattern. However, a high frequency spatial carrier which is sometimes not easy to generate is required to solve the phase ambiguity problem. In this paper, we aim to propose an ideal solution for dynamic phase measurement. Four images with known phase shift are captured at the reference stage to analyze the initial phase information. After the object starts continuous deformation, only one image is captured at each deformed stage. A clustering phase extraction method is then applied for deformation phase extraction utilizing the phase clustering effect within a small region. This method works well for speckle image with low and medium fringe density. When the fringe density is high, especially in the case of shearographic fringe, information insufficiency inherent with merely one deformed speckle image often results in poor quality wrapped phase map with plenty of phase residues, which make phase unwrapping a difficult task. In the light of this limitation, a Fourier transform based phase filtering method is proposed for fringe frequency analysis and adaptive filtering, and effectively removes most of the phase residues to reconstruct a high quality wrapped phase map. Several real experiments based on shearography are presented. Comparison between the proposed solution and standard phase evaluation methods is also given. The results demonstrate the effectiveness of the proposed integrated dynamic phase extraction method.
