Disturbance Observer-Based Anti-windup Control for Path-Following of Underactuated AUVs via Singular Perturbations: Theory and Experiment
Authors: Lei Ming , Li Ye , Zhang Tiedong , Jiang Dapeng
Published: May 2023

Path-following is a fundamental motion control problem for AUVs. Despite a number of nonlinear control techniques having offered new tools and promising solutions to deal with the path-following problem of AUVs subject to model uncertainties and actuator saturation, they typically nonetheless yield relatively complicated controllers which may be prohibitive in the real world. Motivated by that, this paper aims to develop an alternative anti-windup control scheme, which should be capable of achieving satisfactory control performance, as well as be easy-to-implement in practical cases. To this end, it suggests a new approach using the theory of singular perturbation and time scales. In this paper, we first make good use of the difference between the bandwidths for observer and vehicle dynamics to design and analyze the DO, so as to provides a new physical perspective. We then show how such three-time scale singular perturbation control law can be designed. This can provide a deep insight into the dynamic response of closed-loop system in a geometric view. Following that, we propose a novel anti-windup modification, based on the physical perspective and the “geometric view” mentioned above. Simulation results and experiment results suggest that this approach is feasible. Although our motivating application is to the path-following of AUVs in the horizontal plane, the proposed control method is applicable to a variety of problems in control community, in which the time-scale separation widely exists. In future research, we will extend the proposed method to three-dimensional (3D) path-following, as well as apply the singular perturbation technique to reduce the computation complexity of MPC and Neural Network control. Additionally, as the PI/PID controllers usually suffer from the difficulties of selecting proper control gains, it is also expected that the singular perturbation theory can be employed for solving this problem, by taking advantages of the physical perspective.
A Transformer-based Network with Differential Feature Triple Refinement for Bitemporal Remote Sensing Image Change Detection
Authors: Chang Hao , Sun Xian , Wang Peijin , Diao Wenhui , Xu Guangluan
Published: May 2023

In change detection (CD), how to reduce the interferences of pseudo changes and accurately recognize the change of interest (COI) are two important challenges. Recently, considering the powerful long-distance modeling ability of the transformer, some methods try to introduce the transformer into CD and have already proposed several useful CD strategies. However, the existing strategies either do not directly work on the change of interest (COI) or are difficult to give full play to the advantages of the transformer. Therefore, in this paper, we propose a new CD strategy to tackle the above challenges. Specifically, we focus on the difference domain and propose the differential feature triple refinement strategy to precisely characterize COI. We first adopt a CNN-based differential feature extraction (DFET) module to extract the possible detail differences between bitemporal images. Then, we introduce a transformer-based differential feature enhancement (DFEH) module to capture and enhance the COI regions from the preliminarily extracted differences. Finally, we utilize a CNN-based differential feature fusion (DFFS) module to integrate the fine-grained information into the enhanced COI regions. Based on the proposed strategy, we design a new network named DiFormer. We verify six effective hyperparameter configurations and conduct experiments on four commonly researched CD datasets. Extensive experiment results indicate that our proposed strategy has the outstanding generalization ability and obtains the better balance between computation costs and model performance. Peculiarly, when only adopting the Natural Scene Image Pretraining (NSIP), our method still exceeds the recently proposed CD methods which especially focus on the improvement of Remote Sensing Image Pretraining (RSIP).
Overheid en burgerij: tot elkaar veroordeeld? Naar een civiele bestuurskunde voorbij de verzorgingsstaat
Authors: Basten Floor
Published: May 2023

Het Nederlandse openbaar bestuur kent een traditie waarin met een zekere mate van argwaan en misprijzen wordt gekeken naar initiatieven van burgers. Die conclusie moeten we tenminste welhaast trekken wanneer we in de bestuurskundige literatuur zien dat hiernaar verwezen wordt als ware het een ziekte (Hollanditis) of in elk geval een last (hindermacht) (Basten & Van der Veen, 2000). Van hun kant koesteren burgers een traditioneel wantrouwen jegens hun overheid, vooral wanneer die zich te veel met hen gaat bemoeien. Toch zien we nieuwe trends in de samenwerking tussen burgers en overheden die met deze traditie lijken te breken. Voor een deel hangen die samen met het dreigende failliet van de verzorgingsstaat, maar deze nieuwe samenwerkingsvormen worden ook mogelijk gemaakt door een algehele opwaartse gang van de samenleving naar betere opleidingen, betere banen en betere toegang tot kennis en informatie. Hoe het ook zij, vanaf de jaren zestig van de vorige eeuw werken overheid en burgers steeds meer samen, al is het niet altijd even productief of vrijwillig. In dit hoofdstuk zal ik stilstaan bij de disciplinerende houding van de overheid jegens haar burgers enerzijds en de initiatieven die burgers nemen anderzijds.

Published: May 2023

Hoewel de percentages iets variëren in de diverse onderzoeken staat vast dat zeven tot twaalf procent van de kinderen en jeugdigen psychosociale en/of psychiatrische problemen heeft, waarvan bij drie à vijf procent sprake is van ernstige problematiek. Deze problemen betreffen hun emoties, cognities, gedrag en/of relaties. In de jeugdhulp en jeugd-GGZ, zoals deze vanaf 2015 is georganiseerd, wordt ernaar gestreefd om noodzakelijke hulp zo dicht mogelijk bij huis (in de buurt, in de wijk) te laten plaatsvinden. Dit zal gebeuren door als generalisten opgeleide hulpverleners en vanuit de gedachte: één kind, één regisseur, één plan. Toch zal, gezien hun complexe, samengestelde problematiek voor ongeveer een derde van de kinderen, jeugdigen en hun gezinnen meer nodig zijn. Dit boek werkt uit wat aan een succesvolle behandeling in geval van samengestelde, complexe problematiek vooraf gaat. Hoe wordt de hulpvraag verduidelijkt, hoe te komen tot gedeelde diagnostische inzichten, hoe de gezamenlijke dialoog te voeren en gezamenlijk beslissingen te nemen, hoe van behandelingsplanning een proces te maken en dit weer te geven in een behandelingsplan. George Westermann en Jac Maurer, de ontwikkelaars van het Dialoogmodel, en Fop Verheij, die meerdere boeken over behandelingsplanning schreef, combineren in dit boek hun gedeeld gedachtegoed. Het boek biedt antwoord op de vraag hoe in de jeugdhulp te adviseren en te plannen bij complexe, samengestelde problematiek van kind, jeugdige en gezin.

Published: May 2023

Background: One of the most common cancers in the world is c1olorectal cancer. Surgery is the sole curative option, and post-operative morbidity and mortality should be kept to a minimum to enhance results. Of course, the whole surgical and medical team is extremely frustrated when post-operative complications finally result in patient death. Because colon cancer patients tend to be older, it is to be expected that a growing percentage of patients have co-morbidity, making any procedure riskier. Patients may lose their lives even after successful surgery as a result of co-morbidity-related consequences. The main method of therapy for colorectal cancer is still surgery. However, the procedure entails a high risk of morbidity and death and uses a substantial amount of medical resources. Postoperative complications are common in patients who have had colorectal surgery, and they put them at increased risk for morbidity, mortality, poor oncologic outcomes, and a reduced quality of life. Objective: To find out associated risk factors of the patients related to colorectal cancer and the outcome of resection surgery of colorectal cancer. Materials and Methods: After receiving ethical permission, the department of surgery at Rangpur Medical College Hospital carried out this longitudinal form of descriptive study between July 2019 and June 2020. After explaining the nature and goal of the study to the participants, signed informed permission was acquired. A pre-made questionnaire was used to interview a total of 33 patients. Each patient had a complete physical examination, a careful history review, and any necessary investigations. Based on pre-existing co-morbidities, surgical technique, and associated complications, 30-day postoperative mortality and morbidity were assessed. The case questionnaire contained the collected data. ANOVA, Fisher exact, and the appropriate statistical tests (Chi-square) were run. Software called SPSS (version 22.0) was used to examine the data.

Acute oxalate nephropathy, caused by either primary or secondary hyperoxaluria, is characterized by the presence of tubulointerstitial deposits of oxalate, accompanied by an interstitial inflammatory reaction. We report the case of a type 2 diabetic patient who developed terminal chronic renal failure on acute oxalate nephropathy. The patient was seen in the Emergencies Department with a loss of cutaneous substance at the level of the wrist with a whitish suppurative deposit. The radiological assessment showed various joint opacities at the level of the wrist, the metacarpophalangeal and interphalangeal joints. A non-regressive ARF (particularly in a diabetic patient) should lead to a search for exocrine pancreatic insufficiency with secondary hyperoxaluria. A kidney biopsy should be performed quickly to support this diagnostic suspicion.

Hal yang paling penting dalam konsep pendidikan agama islam adalah adanya sebuah konsep fitrah manusia. Fitrah manusia tidak selalu identik dengan teori kertas kosong atau tabularasa, sebab kata tabulrasa seperti yang di praktekkan oleh john locke yang hanya melihat manusia itu seperti kertas putih, ibarat kertas yang belum di coret, sehingga pengaruh lingkungan itu sangat berdampak dan adanya pendidikan menjadi hal yang sangat penting. Di dalam fitrah manusia terdapat potensi bawaan yang dibawa oleh manusia yakni potensi daya atau kekuatan untuk bisa menerima sebuah tauhid atau agama islam maka dari itu dalam adanya lingkungan dan keluarga sangat mempengaruhi dan strategis dalam mengembangkan fitrah manusia itu sendri, dengan artian kalau anak di arahkan kepada hal yang positif dan baik maka akan terarah dan menjadikan dirinya sebegai penerus bangsa regenerasi bangsa yang cinta damai, tentram, inklusif, dan terus mengembangkan. Hal tersebut Menunjukkan bahwa Manusia dengan segala potensinya, sanggup merealesasikan apa yang sudah menjadi keinginannya, proses mengembangkan kemampuan yang dimiliki melalui pendidikan tidak menjadi jaminan dalam membentuk krakter dan bakat menuju insan yang baik dan menjadi kebanggaan dan disenangi oleh semuanya terlebih di cintai penciptanya, maka dari hal itu adanya sebuah pendidikan agama Islam selalu memberikan hal yang baru dan selalu mewarnai hidup kita sesuai dengan potensi yang dimiliki oleh manusia itu sendri.

Peace building literacy assistance to refugees of the Madurese conflict in Pamekasan Regency is an urgent step as a preventive measure for subsequent conflicts that continue to haunt Madurese refugees in Pamekasan. The refugees must obtain comprehensive knowledge about the diversity of the Republic of Indonesia through an approach that suits their characteristics, namely a persuasive da'wah approach as an effort to operationalize friendly Islamic teachings in a concrete form. This is because the refugees still have a high desire to return to Kalimantan someday. In fact, many of their family members had already returned to the island of Borneo to seek fortune as they had before the bloody events several decades ago which became a black record for the Indonesian nation. This mentoring activity uses a Word of Mouth approach, namely conveying messages by word of mouth as an individual approach and through "koloman" or halaqoh-halaqoh, namely group activities which have become a habit for Madurese people.

The purpose of this study is to analyze (1) the factors that determine the existence of a misuse of circumstances in a contract; and (2) the basis for the judges consideration in canceling an agreement containing a factor of misuse of circumstances. The research method used is normative legal research. The results of the study show that (1) The determination of the factors of misuse of circumstances in a contract can be seen from (a) the presence of a defect of will in the making of the contract; (b) there are conditions in the agreement that are actually unreasonable or inappropriate or contrary to humanity; (c) the weak party is under pressure; (d) if there are circumstances where the weaker party has no choice but to enter into a contract with onerous terms contained in the contract; and (e) the party is weak, the value of the reciprocal rights and obligations of the two parties is very unequal; (2) The basis for the judges consideration in canceling an agreement that contains a factor of misuse of circumstances by using jurisprudence and a sense of justice, considering that misuse of circumstances in contracts/agreement has not been strictly regulated in the Civil Code or other laws and regulations. Arrangements for misuse of circumstances can also be applied in the event that the agreement contains errors, or oversight (dwaliing), coercion (dwang) and fraud (bedrog), which the weak party feels is very burdensome and contrary to a sense of justice and humanity.

VOLUMETRIC RIGIDITY OF HYDRAULIC SYSTEMS
Authors: Ali-Hikmat Ahmadov Ali-Hikmat Ahmadov , Samir Abbasov Samir Abbasov
Published: May 2023

A hydraulic drive is a set of interacting hydraulic devices that is designed to be ghosted by means of a working fluid under pressure. The main element in hydraulic drives most machines is a power hydraulic cylinder. Hydraulic cylinder refers to volumetric hydraulic devices, since their operating mode is to fill the volume of the working chamber and empty it. The very principle of operation of the hydraulic cylinder is based on the movement of the worker organ (piston, membrane, plunger), under the influence of the energy of the flow fluid or the mechanical energy of external forces (gravity, spring).Depending on the principle of operation of hydraulic cylinders, it can be divided into two groups: one-way hydraulic cylinder, two-acting hydraulic cylinders. To ensure the operation of the hydraulic cylinder, a pump is required, the purpose of which is to convert mechanical energy into the energy of the flow fluid. Studying the stiffness of a hydraulic cylinder can help determine the optimal load that a hydraulic cylinder can withstand, as well as help in choosing the right size of hydraulic cylinder for a particular system. The stiffness of the hydraulic cylinder can be determined by measuring the movement of the hydraulic cylinder as the load increases in a given range. For example, a hydraulic press can be used to increase the load on a hydraulic cylinder to a certain value, and then a measuring tool can be used to determine the movement of the hydraulic cylinder. This data can be recorded on a computer, which can then be used to analyze and calculate the stiffness of the hydraulic cylinder. The stiffness of the hydraulic cylinder can be expressed in newtons per millimeter or other units depending on the specific measurement system. By using various materials (indicated in the literature), the results of studies aimed at determining the reduced volumetric stiffness of high-pressure hoses and the dependence of the reduced volumetric stiffness of the hydraulic cylinder on the change in the volumes of the working cavities in the process of moving its rod are given.
Keywords: hydraulic system, volumetric stiffness, hydraulic cylinder, module, hydromechanical systems, hoses, pressure, rod, dynamics.
IMPROVEMENT OF OPERATING CAPACITY OF OIL PRODUCTION EQUIPMENT CONSIDERING THE INFLUENCE OF DYNAMIC LOADS
Authors: Tahir Suleymanov Tahir Suleymanov , Suleyman Efendi Suleyman Efendi , Aybeniz Amirova Aybeniz Amirova
Published: May 2023

In the presented article, the analysis of the effect of the dynamic load falling on the polished rod of the sucker rod pump unit on the normal function of the operating unit during the oil extraction process was carried out. The general formula for the damage caused by the impact of the pump's wellhead packing seal has been derived. The dependence graph of damaged work on the length of the packing seal and the Poisson's ratio of the material was made.
Due to the dynamics of the frictional force generated in the packing seal of the stuffing box appropriately located below the suspension point of the rods, its forced cyclic movement occurs as a result of the impact transmitted to the system which consists of an incompressible fluid column, and the elastic rods. This requires the investigation of the dynamics of the rod pump associated with the probability of unpleasant situations such as the possible resonance occurrence in the specified system, the time between repairs, and the reduction of the working coefficient of the pump, in this regard.
At the same time, the questions such as the coefficient of friction depending on the selection of the material of the packing seal, the reduction of the dynamic accumulation of the load on the system, and the saving of electric energy are also important. It needs to be considered that the operation process is accompanied by a certain energy loss. It should be taken into account that even a small reduction in energy loss can manifest great economic benefits. It should be noted that some issues encountered in the process of operation of oil wells through the rod pump and depending on certain arguments affecting this process were also resolved by those experts.

Authors: Tseng Judy C. R. , Li Wei
Published: May 2023

With the advent of the digital age, countries worldwide have begun to emphasize computational thinking education, hoping to cultivate learners' abilities to meet the requirements of future talents. Currently, computational thinking education in young children is mainly based on visual programming on computers or robots. However, using computers requires a prior understanding of abstract thinking, which is difficult for young children to master. To meet the need for cultivating computational thinking in younger children, this study combines a tangible robot with a verbal user interface to develop a set of voice-activated programming robots suitable for younger children. The learner gives verbal commands to make the robot perform the specified actions and complete the problem-solving task. This approach allows children to ignore the syntax of the programming language and thus focus more on problem-solving.

With the increasing number of hypertensive patients who often appear without symptoms and are influenced by various factors, a technique for controlling blood pressure is needed such as self-care management and self-efficacy. The purpose of this study was to determine the relationship between self-efficacy and self-care management in patients with hypertension. Method: This research is a quantitative type with a cross-sectional approach. Samples were taken using a total sampling technique with a total of 66 samples. The instruments used are the Self-efficacy to Manage Hypertension-Five Item Scale and Hypertension Self-Care Management Behavior. Results: The results showed that 53 (80.3%) respondents had poor self-efficacy, and 54 (81.8%) patients had good self-care management. There was a significant relationship between self-efficacy and self-care management in hypertension sufferers with a p-value value of 0.000. It is recommended that people with hypertension can increase their self-efficacy in order to achieve good and stable self-care management of hypertension, for future researchers to be able to use a self-efficacy questionnaire that more accurately determines the range of good and bad, and also adds other variables that can be factors that influence affect self-care management such as education level, history of knowledge, gender, and lifestyle.

Objetivo: O uso da Inteligência Artificial (IA) na vida das pessoas com desafios de acessibilidade, pode abranger não apenas as deficiências físicas, mas também as de pessoas com deficiência intelectual. As diferentes tecnologias que englobam essas áreas visam minimizar os desafios e resolver problemas de acessibilidade. Métodos: O presente estudo foi estruturado através de uma pesquisa bibliográfica com perfil quantitativo. Analisando dados relacionados às produções cientificas sobre IA e acessibilidade, usando descritores – Inteligência Artificial e Acessibilidade – relacionados ao tema e analisando as informações. Resultados: Os dados obtidos foram transcritos em forma de gráficos e tabelas, de forma a organizar o conteúdo. As pesquisas científicas que relacionam IA e acessibilidade no Brasil ainda são pequenas em número. Em contrapartida, tratando de IA em geral, sem especificar “acessibilidade” na busca, percebe-se que o número de artigos é crescente em todo o mundo. Conclusão: O uso das tecnologias deveria ser pensado não apenas para gerar lucro, mas para ajudar pessoas com deficiências, sejam elas físicas ou intelectuais. Estudos sobre essa temática tem aumentado lentamente ao longo dos anos. Já existem ferramentas desenvolvidas e outras em desenvolvimento para esse público, mas em contrapartida ainda há um longo caminho a percorrer em relação ao uso da inteligência artificial para melhorar a acessibilidade.
