Authors: Sabihaini Sabihaini , Astuti Sri , Perwira Rifki Indra , Marita Marita
Published: June 2023

The Covid-19 pandemic, which has been around for about 2 years, has impacted all sectors, especially the economic and industrial sectors. For SMEs, the Covid-19 pandemic is a challenge for cost and financial disruptions, activity disruptions, and existence difficulties. Many companies and SMEs have experienced bankruptcy and were unable to survive amid the Covid- 19 pandemic outbreak. Therefore, this research was established to propose antecedent strategic alignment that can build business resilience. In this study, the unit of analysis is SMEs in Sleman, Yogyakarta. The sample in this study was 94 SMEs. The analysis outcome of this study indicates that communication between business management and information technology management, strategic information system planning, information technology infrastructure flexibility, and environmental uncertainty have an effect and can become an antecedent of strategic alignment and in the end, strategic alignment has an effect on business resilience in a positive and significant way. The findings are interesting because it turns out that during the Covid-19 pandemic, strategic alignment can be a predictor of business resilience. Where business resilience has the nature of proactive anticipation before turbulence, adaptive when turbulence occurs, and reactive after turbulence occurs. And this is also the novelty of this research.
Understanding Blended Finance: How different definitions of blended finance result in different inputs and outputs and what to expect
Authors: Al Anshori Farahdina , Salomo Roy Valiant , Kusumastuti Retno
Published: June 2023

Several breakthroughs were made to achieve the SDGs targets, including in the development funding subject, namely blended finance. As a new approach to development financing, this approach is not yet widely understood. One of the basic problems is that there is no internationally agreed definition of what blended finance is. The actors translate this concept according to the characteristics of their respective institutions. This translation causes a variety of blended finance, from the types of input in the blended finance operation, what output is produced from the collaboration, to what impact these institutions expect from the blended finance project they are involved. This paper examines the definitions of blended finance from four institutions commonly involved in blended finance projects, i.e. OECD, DFI, Convergence, and the European Union. By reviewing a selection of reports and their working papers, it can be concluded that the input, output, and impact expected by these actors depend on the blended finance definition they make respectively. Actors whose definition focuses on development are more toward developmental impact, while actors whose definition focuses on an economic perspective prefer focusing on projects with profit-oriented impacts. Understanding the matter will help those new players in blended finance, including policymakers, to decide which partner is more suitable to collaborate in which phase of blended finance.
Alternatives to Christian education. Atheist propaganda in Romanian schools during the communist period (The case of Mureș County)
Authors: Pășcan Sabin-Gavril
Published: June 2023

The communist regime in our country imposed atheism on the masses. In a state where morality and common sense were deeply linked to religion (Christian-Orthodox, Mosaic or Islamic) the concerted attacks by the communist regime, following the Stalinist model in the USSR of the 1920s, emptied people's conscience of any natural value scale. After the Second World War and the establishment of the communist regime in Romania, the influence of churches and religious institutions in public education was significantly reduced, and denominational schools were abolished or transformed into state schools. The education reform of 1948 also had an important impact on confessional education in Mureș County.
The concepts of arrangement in case fees in civil cases
Authors: Sumargi  , Slamet Suhartono  , Yovita Arie Mangesti  , Atik Krustiati
Published: June 2023

The principle of paying court costs in civil courts is borne by the losing party. The payment for the court fee is taken from the down payment for the court fee paid by the plaintiff. The judge's decision regarding the imposition of court fees on the losing party is a punitive decision, so it must be carried out by the losing party. According to Abdul Kadir Muhamad, when a decision has been enforced, there is no longer any opportunity to use ordinary legal remedies against the decision. Therefore, the judge's decision which has permanent force (incracht van gewijsde) must be implemented without delay.

Authors: Manawan Christin Carly Merry , Masengi Evi Elvira , Wawointana Thelma
Published: June 2023

This study aims to identify, analyze and describe what factors influence the competence of the Auditor and PPUPD (Supervisor of the Implementation of Local Government Affairs) at the Regional Inspectorate of Tomohon City. In this study, the authors used a qualitative approach that is descriptive in nature, namely explaining the phenomenon in depth through data collection. Based on the results of the study it was found that the competence of Auditors and PPUPD had been implemented. This can be seen from the several indicators that have been discussed, namely, the Auditors and PPUPD who carry out supervisory duties must have sufficient competence. Auditors and PPUPD before carrying out their duties always try to equip themselves with knowledge related to the implementation of the tasks they will carry out. In order to improve the competence of Auditors and PPUPD in carrying out supervisory duties, training is carried out in the office itself concerning the rules relating to the implementation of supervisory assignments. The office training itself also discussed the mechanisms for implementing supervisory assignments. To increase the competence of Auditors and PPUPD in the implementation of supervision, before carrying out supervisory duties, Auditors and PPUPD must prepare an Audit Work Program (PKA), Review Work Program (PKR) as guidelines regarding the design of work procedures systematically, also known as work steps will be implemented to achieve the goal. The Inspectorate, which is the Government's Internal Supervisory Apparatus (APIP) as a Strategic Partner, certainly has many tasks as well as obstacles in the work that are faced within the Internal and External scope. The competence of the Auditor and PPUPD must be maximized and requires a budget that is arranged in the Budget Implementation Document (DPA) of the regional apparatus, in this case, the Inspectorate. Not all Auditors and PPUPD have the opportunity to be involved in training and education regarding the implementation of supervisory duties because the available budget is very limited.

SERVICOM and Public Service Delivery in Nigeria: A study of Akwa Ibom State University
Authors: Ikhenoba Williams , Atakpa Dr. Ofonmbuk Etido
Published: June 2023

The quality, efficiency and impact of public service delivery remains an issue of grave concern in Nigeria as the Nation is known for its endemic poor public service delivery and productivity. To tackle this vice, its former President, Olusegun Obasanjo in March 2004, using its administrative powers ordered the establishment of SERVICOM Units in all Federal government ministries, departments and parastatals. This would later extend to the National Universities Commission and all Federal and State Universities in Nigeria. A synthesis of the SERVICOM charter shows that its central focus is on enhancing quality and measurable service delivery. The literature review and the theoretical framework grounded on Douglas McGregor’s famous Theory X and Y revealed that a third party inspector such as SERVICOM is a necessity in the public service delivery chain to ensure public services are delivered in a quantitative, qualitative, customer centric, affordable, accessible and predictable manner. Using a survey research and ANOVA, the researchers found that 93.80% of the respondents have not received the necessary awareness on the services of SERVICOM while 88.08% confirm that SERVICOM has not been monitoring their services. The study concludes that the inability to provide the needed awareness and monitoring had a significant negative effect on staff service delivery. It then made useful recommendations such as immediate commencement of a structured awareness programmes, monitoring and alignment with its sister unit in the institution towards the realization of the SERVICOM mandate.

Hearing Aid System Response Improvement
Authors: Parmar Pamraat , Sands Timothy
Published: June 2023

This study was conducted to understand the response of hearing aids to different inputs and propose a novel technique to significantly improve performance of hearing aid implants. The motivation behind this study is to represent behavior of hearing aid system with simple input-output relation rather than complicated models. This representation offered a better understanding of the system and inspired an innovation to improve the hearing aid implants. A model of a hearing aid system called cochlear transplants is generated and used to simulate the system response. Using multiple methods, simplified input-output relations are derived. Results from these methods are compared and conclusions are drawn regarding which method is best for this application. One of the methods used resulted in 69.7 % error measure reduction compared to the benchmark method. This method was later used to produce a simplified model, which was then used as the basis for analysis of different configurations. A qualitative comparison of model was made, and significant improvement of cochlear transplants was achieved.

Authors: LALI Chigladze , GULNARA Badridze , ETER Maghradze
Published: June 2023

Background: Antioxidant compounds are widely used in medicine to protect the organism from the impact of various stresses and strengthen the immune system. The primary source of natural antioxidants is considered plant-based products. That is precisely why scientists are interested in extracting active compounds out of plant materials and use them. However, diverse resources of medicinal plants of Georgia is poorly studied and used as a source of antioxidants. Aim: The research aimed to study the antioxidant composition and total antioxidant activity of some dried medicinal plants sold in the pharmacy network in Tbilisi, Georgia. Methods: Several types of medicinal plants (3 berry plants and 3 herbaceous plants) sold in the pharmacy chain were chosen as the research object. These are Crataegus sp., Sorbus sp., Viburnum sp., Helichrysum sp., Leonurus quinquelobatus Gilib, Origanum vulgare L. Results: As a result, it has been found that the content of ascorbic acid and carotene in the studied plants is not so high to fill the daily intake of a man with an infusion prepared from one tablespoon. As for proline and the number of total antioxidants, all the plants we have chosen are high in content, considerably increasing their medicinal value. Discussion: The low amount of ascorbic acid and carotine found in studied plant, this increases their medicinal value, and in combination with other antioxidants/plants, the healing effect of the raw materials has been used. Conclusions: The studied plants are characterized by high levels of proline and antioxidant activity, so their infusions can be safely used as a source of antioxidants both in folk medicine and for the preparation of biologically active preparations.

Background: Sugarcane juice is an excellent substrate for the growth of a large and diverse microbiota, and poor quality of it can affect the health of consumers. This study aimed to evaluate the acidity parameters of the juice extracted from minimally processed sugarcane at three different points in Cuiabá - MT. Methods: In the juice samples, the following parameters were analyzed: Brix (soluble solids), pH, acetic (volatile) acidity, and sulfuric (total) acidity. Results: All the Brix values were above 18. The pH values were between 5 and 6. The total and volatile acidity was below 0.8. Discussion: The Brix values found in this study are similar to other studies (standard deviation of 1.7). The variety of sugarcane significantly influences the Brix and its sampling period. Inappropriate handling of sugarcane promotes the microbiological decrease of the final product. The pH values were satisfactory, but the changes in temperature in one of the juices (sudden change from 24 to 22.7ºC) caused its pH to differ from the value found for the others. The total and volatile acidity content is related to the storage time of the juice, which can be contaminated by bacteria and microorganisms, affecting the characteristics of the product. When the acidity value is more significant than 0.8, there was a change in these characteristics, which did not happen in this work. Conclusions: The Brix values indicate an adequate maturation of the analyzed juices. The pH values are in the ideal range for sugarcane juice. The volatile and total acidity is in the ideal range, indicating quality standards for sugarcane juice.

Published: June 2023

La cinematica y dinámica de mecanismos paralelos es un campo de investigación donde tradicionalmente se realizan los análisis de los mecanismos empleando la teoría de los torsores. En este artículo se presenta un enfoque alternativo, basado en la teoría de grupos y álgebra de Lie, el cual es un método que ha sido utilizado de manera exitosa en el análisis de cadenas cinemáticas abiertas. El artículo inicia con una breve introducción a las cadenas cinemáticas abiertas y su algebra de Lie, y posteriormente aplica dichos conceptos a los mecanismos paralelos. El artículo se ha redactado utilizando unicamente álgebra de vectores y matrices, con el objetivo de cubrir la mayor cantidad de investigadores del campo de la Robótica. En ese sentido, se analizan ejemplos típicos de robots paralelos en forma de tutorial, entre los que se encuentran, el mecanismo de cinco barras, el mecanismo de cuatro barras espacial y el robot 3-RRR planar. Se espera que el enfoque practico dado al presente artículo contribuya a fomentar el uso del algebra de Lie para el análisis cinemático y dinámico de mecanismos paralelos.

Published: June 2023

En este trabajo se aborda el problema del modelado de un cuello robótico blando mediante el uso de diferentes arquitecturas de redes neuronales, estudiando la influencia en los resultados del número de capas de cada red y de su correspondiente función de activación. Se emplearan las funciones de activación Tangente Hiperbólica (TANH) y Unidad Lineal Exponencial (ELU). Los modelos obtenidos se compararan con un modelo basado en Perceptron Multicapa (MLP) de parámetros optimizados, así comocon el modelo cinemático analítico del cuello. Los resultados experimentales obtenidos demostraran la ventaja del empleo de las técnicas de aprendizaje automático para el modelado de sistemas altamente no lineales como el del cuello robótico blando, cuya característica elástica dificulta la formulación de un modelo analítico robusto.

Trayectorias de máxima rigidez de un robot redundante actuando como soporte en el mecanizado de paredes delgadas
Authors: Aginaga Jokin , García-Cuesta Iván , Iriarte Xabier , Plaza Aitor
Published: June 2023

La precisión de un robot está ligada a su rigidez. En comparación con la máquina herramienta tradicional, los robots industriales tienen un gran espacio de trabajo como ventaja, pero una rigidez reducida como desventaja. Además, la rigidez tiene una gran dependencia y variabilidad con la postura o configuración del robot. De ahí que resulte necesario un análisis de rigidez de los robots, que se evalúa mediante la matriz de rigidez. En este trabajo se presenta un análisis de rigidez de un robot serie. Ante la diversidad de índices representativos extraídos a partir de la matriz de rigidez, se ha propuesto el uso de un índice que tenga en cuenta la dirección de las cargas que soporta el robot y la dirección en que se desea que el robot aporte rigidez en la aplicación específica. Asimismo, se ha utilizado el índice de rigidez para llevar el robot a configuraciones que mejoren la rigidez, hecho que resulta posible en aplicaciones en las que el robot tiene al menos un grado de libertad (GDL) redundante. La metodología se ha aplicado a un robot de 7 GDL utilizado como robot de soporte en el mecanizado de paredes delgadas. Dado que para definir latrayectoria únicamente son necesarios 5 GDL, se utilizan 2 GDL reduntantes para mejorar la rigidez.

Published: June 2023

En este artículo se plantea el problema de optimización de una ley de control para minimizar el error cuadrático integral al conducir un AUV (Autonomous Underwater Vehicle, vehículo autónomo submarino) actuado con un único motor desde un punto de partida hasta una zona de recuperación deseada. Así mismo se muestran dos posibles soluciones de control y se discute su implementación en el vehículo. Para la optimización de la ley de control se utilizarán los algoritmos genéticos y se proponen dos soluciones: En la primera se optimiza la ley de control muestreada en función del tiempo. La segunda, por su parte, emplea una acción de control óptima en función de la orientación del vehículo a partir de una ley de control representada mediante una serie de Fourier. El correcto funcionamiento de las soluciones propuestas se demuestra mediante una serie de simulaciones que consideran distintas condiciones y situaciones posibles.
Control predictivo polifásico mediante dos constelaciones de vectores virtuales de tensión
Authors: Garrido Satué Manuel , Ruiz Arahal Manuel , Rodríguez Ramírez Daniel , Barrero García Federico
Published: June 2023

En el campo de los accionamientos eléctricos de velocidad variable ha aparecido recientemente el método predictivo basado en vectores virtuales de tensión. Este método permite reducir la contribuci´on del voltaje en el subespacio x-y, en el cual no se produce par, sino pérdidas. De este modo no sólo se limitan las pérdidas sino que se reduce la complejidad de sintonía del controlador predictivo. Los vectores virtuales de tensión se obtienen mediante combinación de vectores de tensión pertenencientes a distintas coronas pequeña, media y grande además de los vectores nulos. En una aplicación típica se elige en primer lugar la(s) corona(s) a usar y después se desarrollan los vectores virtuales. El controlador predictivo usa en cada periodo de muestreo el vector virtual más adecuado. En este trabajo se propone el uso de varios conjuntos de vectores virtuales provenientes de diferentes  combinaciones de coronas. Para cada punto de operación del accionamiento eléctrico se utiliza el conjunto que proporciona mejores valores de cierto criterio de bondad. El método propuesto es validado experimentalmente usando una máquina de inducción de seis fases.

SEJARAH PEMBANGUNAN BANDARAYA KOTA KINABALU, 1881-1962
Authors: Baco Zainuddin , Bala Bilcher
Published: June 2023

Bandaraya Kota Kinabalu merupakan antara bandar awal terancang yang diwujudkan oleh British North Borneo Chartered Company (BNBCC) pada Julai 1889. Dari aspek sejarah, penubuhan bandar ini berkait rapat dengan langkah pembinaan sistem pengangkutan kereta api di kawasan pantai barat Borneo Utara. Walaupun sekitar tahun 1889 sehingga tahun 1942 telah memperlihatkan Bandar Jesselton berkembang dengan lebih perlahan berbanding Bandar Sandakan (Elopura), tetapi pasca Perang Dunia Kedua yang memperlihatkan Bandar Jesselton menjadi ibu negeri Borneo Utara. Keadaan ini secara tidak langsung menyebabkan tumpuan pembangunan dan ekonomi adalah ke arah wilayah ini. Justeru, untuk mengembalikan satu sistem pentadbiran yang tersusun di Borneo Utara, maka langkah pembinaan semula dan pembangunan infrastruktur kekal dilaksanakan dengan begitu pesat seperti pembinaan kekal bangunan pentadbiran, rumah penjawat awam, deretan kedai, landasan kapal terbang, hospital dan lain-lain. Langkah pembangunan infrastruktur dan ekonomi di wilayah ini telah menyebabkan Bandar Kota Kinabalu menjadi sebuah bandaraya pada tahun 2000. Oleh itu, artikel ini akan memperincikan sejarah pembangunan Bandaraya Kota Kinabalu dari tahun sebelum 1881 sehingga pembentukan Malaysia pada tahun 1963. Perincian sejarah pembangunan ini akan diteliti berdasarkan empat fasa penting, iaitu (i) Kota Kinabalu sebelum tahun 1899; (ii) Kota Kinabalu era pentadbiran BNBCC (1898-1942); (iii) Kota Kinabalu era pendudukan Jepun (1942-1945); (iv)Kota Kinabalu Pasca Perang Dunia Kedua (1945-1962).

No período de janeiro a março do ano de 2023, em um centro veterinário, foram aplicados 75 questionários para tutores de cães e gatos acerca do conhecimento das verminoses que acometem seus animais de companhia e após encaminharam as fezes desses animais para a realização do exame coproparasitológico. Dentre os resultados obtidos notou-se que os proprietários possuem um baixo conhecimento sobre as verminoses (formas de transmissão, potencial zoonótico, tratamentos, relação com o desenvolvimento do animal) e no coproparasitológico com a utilização dos métodos de Wiilis Mollay e Hoffman se teve a maior prevalência do gênero Ancylostoma sp. (73,33%). Com os resultados de exame parasitológico, nos casos positivos para algum gênero de helmintos ou protozoários, foi prescrita medicação adequada ao parasita encontrado.
Uncertainty in parameterized convection remains a key obstacle for estimating surface fluxes of carbon dioxide
Authors: Schuh Andrew E. , Jacobson Andrew R.
Published: June 2023

Abstract. The analysis of observed atmospheric trace-gas mole fractions to infer surface sources and sinks of chemical species relies heavily on simulated atmospheric transport. The chemical transport models (CTMs) used in flux-inversion models are commonly configured to reproduce the atmospheric transport of a general circulation model (GCM) as closely as possible. CTMs generally have the dual advantages of computational efficiency and improved tracer conservation compared to their parent GCMs, but they usually simplify the representations of important processes. This is especially the case for high-frequency vertical motions associated with diffusion and convection. Using common-flux experiments, we quantify the importance of parameterized vertical processes for explaining systematic differences in tracer transport between two commonly used CTMs. We find that differences in modeled column-average CO2 are strongly correlated with the differences in the models' convection. The parameterization of diffusion is more important near the surface due to its role in representing planetary-boundary-layer (PBL) mixing. Accordingly, simulated near-surface in situ measurements are more strongly impacted by this process than are simulated total-column averages. Both diffusive and convective vertical mixing tend to ventilate the lower atmosphere, so near-surface measurements may only constrain the net vertical mixing and not the balance between these two processes. Remote-sensing-based retrievals of total-column CO2, with their increased sensitivity to convection, may provide important new constraints on parameterized vertical motions.
The (mis)identification of high-latitude dust events using remote sensing methods in the Yukon, Canada: a sub-daily variability analysis
Authors: Huck Rosemary , Bryant Robert G. , King James
Published: June 2023

Abstract. The observation and quantification of mineral dust fluxes from high-latitude
sources remains difficult due to a known paucity of year-round in situ
observations and known limitations of satellite remote sensing data (e.g.
cloud cover and dust detection). Here we explore the chronology of dust
emissions at a known and instrumented high-latitude dust source:
Lhù'ààn Mân (Kluane Lake) in Yukon, Canada. At this location
we use oblique time-lapse (RC) cameras as a baseline for analysis of aerosol
retrievals from in situ metrological data, AERONET, and co-incident MODIS
MAIAC to (i) investigate the daily to annual chronology of dust emissions
recorded by these instrumental and remote sensing methods (at timescales
ranging from minutes to years) and (ii) use data intercomparisons to
comment on the principal factors that control the detection of dust in each
case. Lhù'ààn Mân is a prolific mineral dust source; on
24 May 2018 the RC captured dust in motion throughout the entire day, with
the longest dust-free period lasting only 30 min. When compared with
time series of RC data, optimized AERONET data only manage an overall 26 % detection rate for events (sub-day) but 100 % detection rate for dust
event days (DEDs) when dust was within the field of view. In this
instance, RC and remote sensing data were able to suggest that the low event
detection rate was attributed to fundamental variations in dust advection
trajectory, dust plume height, and inherent restrictions in sun angle at
high latitudes. Working with a time series of optimized aerosol optical depth (AOD) data (covering
2018/2019), we were able to investigate the gross impacts of data quality (DQ) choice on
DED detection at the month or year scale. Relative to ground observations,
AERONET's DQ2.0 cloud-screening algorithm may remove as much as 97 % of
known dust events (3 % detection). Finally, when undertaking an AOD
comparison for DED and non-DED retrievals, we find that cloud screening of
MODIS/AERONET lead to a combined low sample of co-incident dust events and
weak correlations between retrievals. Our results quantify and explain the
extent of under-representation of dust in both ground and space remote
sensing methods; this is a factor that impacts on the effective calibration and
validation of global climate and dust models.
Technical note: Constraining the hydroxyl (OH) radical in the tropics with satellite observations of its drivers – first steps toward assessing the feasibility of a global observation strategy

Abstract. Despite its importance in controlling the abundance of methane (CH4)
and a myriad of other tropospheric species, the hydroxyl radical (OH) is
poorly constrained due to its large spatial heterogeneity and the inability
to measure tropospheric OH with satellites. Here, we present a methodology
to infer tropospheric column OH (TCOH) in the tropics over the open oceans
using a combination of a machine learning model, output from a simulation of
the GEOS model, and satellite observations. Our overall goals are to assess
the feasibility of our methodology, to identify potential limitations, and
to suggest areas of improvement in the current observational network. The
methodology reproduces the variability of TCOH from independent 3D model
output and of observations from the Atmospheric Tomography mission (ATom).
While the methodology also reproduces the magnitude of the 3D model
validation set, the accuracy of the magnitude when applied to observations
is uncertain because current observations are insufficient to fully evaluate
the machine learning model. Despite large uncertainties in some of the
satellite retrievals necessary to infer OH, particularly for NO2 and
formaldehyde (HCHO), current satellite observations are of sufficient quality to apply the
machine learning methodology, resulting in an error comparable to that of
in situ OH observations. Finally, the methodology is not limited to a specific
suite of satellite retrievals. Comparison of TCOH determined from two sets
of retrievals does show, however, that systematic biases in NO2,
resulting both from retrieval algorithm and instrumental differences, lead
to relative biases in the calculated TCOH. Further evaluation of NO2
retrievals in the remote atmosphere is needed to determine their accuracy.
With slight modifications, a similar methodology could likely be expanded to the extratropics and over land, with the benefits of increasing our
understanding of the atmospheric oxidation capacity and, for instance,
informing understanding of recent CH4 trends.

Abstract. In 2021, a group of seven Italian institutions decided to
bring together their know-how, experience, and instruments for measuring the
drop size distribution (DSD) of atmospheric precipitation, giving birth to
the Italian Group of Disdrometry (in Italian named Gruppo Italiano
Disdrometria, GID, https://www.gid-net.it/, last access: 16 May 2023). GID has made
freely available a database of 1 min records of DSD collected by the
disdrometer network along the Italian peninsula. At the time of writing, the
disdrometer network was composed of eight laser disdrometers belonging to six
different Italian institutions (including research centres, universities,
and environmental regional agencies). This work aims to document the
technical aspects of the Italian DSD database consisting of 1 min
sampling data from 2012 to 2021 in a uniform standard format defined within
GID. Although not all the disdrometers have the same data record length, the
DSD data collection effort is the first of its kind in Italy, and from here
onwards, it opens up new opportunities in the surface characterization of
microphysical properties of precipitation in the perspective of climate
records and beyond. The Version 01 GID database can be downloaded at
https://doi.org/10.5281/zenodo.6875801 (Adirosi et al., 2022), while Version
02 can be downloaded at https://doi.org/10.5281/zenodo.7708563 (Adirosi et
al., 2023). The difference among the two versions is the diameter–fall
velocity relation used for the DSD computation.

Abstract. This paper proposes a method for acquiring complete data from the Marine Controlled Source Electromagnetic (MCSEM) transmitter during offshore experiments. The lower computer's modules are designed with STM32 MCU and μC/OS-II real-time operating system, while the upper computer's software is designed using Python language to match the lower computer. This allows workers on the deck to control the lower computer in real-time for high-precision data acquisition, storage, Ethernet file transfer, and other tasks. The joint tests between the lower and upper computers have demonstrated the stability and reliability of the online transmitter system, which provides significant convenience for offshore exploration.
