Rivers are vital for sustaining human life as they foster social development, provide drinking water, maintain aquatic ecosystems, and offer recreational spaces. However, most rivers are being increasingly contaminated by pollutants from non-point sources, urbanization, and other sources. Consequently, real-time river water quality modeling is essential for managing and protecting rivers from contamination, and its significance is growing across various sectors, including public health, agriculture, and water treatment systems. Therefore, a real-time river water quality simulation toolbox was developed using machine learning (ML) and an application program interface (API). To create the toolbox, models that simulated water quality parameters such as chlorophyll a (Chla), dissolved oxygen (DO), total nitrogen (TN), total organic carbon (TOC), and total phosphorus (TP) at each point in the Nakdong River were constructed. The models were constructed using Artificial neural network (ANN), Random Forest (RF), support vector machines (SVM), and data from API. Subsequently, hyperparameter optimization was conducted to enhance the model's performance. During training, the models' performances were evaluated and compared based on the data sampling method and ML algorithms. Models trained with random sampling data outperformed those trained with time-series data. Among the algorithm models that used random sampling data, the RF exhibited the best performance. The average coefficient of determination (R2) values for each water quality simulation with randomly sampled data using RF for DO, TN, TP, Chl-a, and TOC were 0.79, 0.65, 0.74, 0.45, and 0.48, respectively. For ANN, they were 0.7, 0.51, 0.64, 0.35, and 0.35, respectively, and for SVM, they were 0.73, 0.51, 0.59, 0.21, and 0.3, respectively. The Chl-a and TOC models exhibited relatively poor performance, whereas the DO, TN, and TP models demonstrated superior performance. Diversifying the input data variables is necessary

COMPUTER STANDARDS & interfaceS 1998年第1期20卷 1-8页

作者： Spinellis, D Univ Aegean GR-83200 Karlovasi Greece

The architecture, interface, and functionality of the Windows application programming interface (API) make it difficult to master and use effectively, and contribute negatively to the safety, robustness, and portability of the applications developed under it. The API is structured around a large and constantly evolving set of functions and is based on a problematic shared library implementation. The provided interfaces are complicated, nonorthogonal, abuse the type system, cause name-space pollution, and use inconsistent naming conventions. In addition, the functionality of the interface suffers from inconsistency, incompleteness, and inadequate documentation. application developers, programming tool vendors, and Microsoft should face the above problems and provide appropriate solutions.

The Materials application programming interface (API): A simple, flexible and efficient API for materials data based on REpresentational State Transfer (REST) principles

引用

COMPUTATIONAL MATERIALS SCIENCE 2015年 97卷 209-215页

作者： Ong, Shyue Ping Cholia, Shreyas Jain, Anubhav Brafman, Miriam Gunter, Dan Ceder, Gerbrand Persson, Kristin A. Univ Calif San Diego Dept NanoEngn La Jolla CA 92093 USA Univ Calif Berkeley Lawrence Berkeley Natl Lab Berkeley CA 94720 USA MIT Dept Mat Sci & Engn Cambridge MA 02139 USA

In this paper, we describe the Materials application programming interface (API), a simple, flexible and efficient interface to programmatically query and interact with the Materials Project database based on the REpresentational State Transfer (REST) pattern for the web. Since its creation in Aug 2012, the Materials API has been the Materials Project's de facto platform for data access, supporting not only the Materials Project's many collaborative efforts but also enabling new applications and analyses. We will highlight some of these analyses enabled by the Materials API, particularly those requiring consolidation of data on a large number of materials, such as data mining of structural and property trends, and generation of phase diagrams. We will conclude with a discussion of the role of the API in building a community that is developing novel applications and analyses based on Materials Project data. (C) 2014 Elsevier B.V.

Fostering Value Creation with Digital Platforms: A Unified Theory of the application programming interface Design

JOURNAL OF MANAGEMENT INFORMATION SYSTEMS 2020年第1期37卷 251-281页

While many firms in recent years have started to offer public application programming interfaces (APIs), firms struggle with shaping digital platform strategies that align API design with aspired business goals and the demands of external developers. We address the lack of theory that explains the performance impacts of three API archetypes (professional, mediation, and open asset services). We couple survey data from 152 API product managers with manually coded API design classifications. With this data, we conduct cluster and regression analyses that reveal moderating effects of two value creation strategies (economies of scope in production and innovation) on the relationships between API archetype similarity and two API performance outcomes: return on investment and diffusion. We contribute to IS literature by developing a unifying theory that consolidates different theoretical perspectives on API design, by extending current knowledge on the performance effects of API design, and by empirically studying the distinct circumstances under which digital platforms facilitate economies of scope in production or in innovation. Our results provide practical implications on how API providers can align API archetype choice with the value creation strategy and the API's business objective.

The HITRAN application programming interface (HAPI) is presented. HAPI is a free Python library, which extends the capabilities of the HITRANonline interface (***) and can be used to filter and process the structured spectroscopic data. HAPI incorporates a set of tools for spectra simulation accounting for the temperature, pressure, optical path length, and instrument properties. HAPI is aimed to facilitate the spectroscopic data analysis and the spectra simulation based on the line-by-line data, such as from the HITRAN database [JQSRT (2013) 130, 4-50], allowing the usage of the non-Voigt line profile parameters, custom temperature and pressure dependences, and partition sums. The HAPI functions allow the user to control the spectra simulation and data filtering process via a set of the function parameters. HAPI can be obtained at its homepage ***/hapi.

Design of buckling restrained steel braces using application programming interface between simulation and discrete optimization

In this study, buckling restrained braces (BRBs) are optimized through application programming interface be-tween simulation and discrete optimization. It is aimed to maximize the energy dissipation capacity of BRBs considering the American Institute of Steel Construction (ANSI/AISC 341). Unlike other studies, BRBs modeled in the finite element packaged software are directly linked to optimization algorithms. So, the geometric and material nonlinearities are also considered. Harmony Search Algorithm (HSA), which simulates the improvisa-tion musician performances in finding pleasing harmony, and Black Widow Optimization Algorithm (BWOA), which imitates inimitable paring attitude of black widow spiders, are taken as the optimizer tools of this study. They encoded in Microsoft Visual Basic programming language. Initially, the algorithmic performances of the HSA and BWOA are compared and evaluated on two benchmark structural engineering design problems. Af-terward, two different shaped BRBs are modeled in a finite element analysis (FEA) based software, namely ANSYS Workbench. Then, the obtained simulations are integrated with the HS and BWO algorithms throughout the application programming interface without identification of complex objective function and design con-straints in formulations. These are directly calculated by ANSYS Workbench over very simple formulas. So, the attained optimum designs of BRBs are investigated with a new approach. Furthermore, in order to see the su-preme algorithmic performances of the HSA and BWOA, all benchmark and BRB design problems are solved so-called well-established conventional standard Genetic Algorithm (sGA). Eventually, the proposed novel design methodology gives opportunity and eases to the designers since it provides convenience in solving complicated problems having nonlinear objective function and design constraints that are tiresome to encode.

The purpose of this study is to perform a synthesis of API research. The study took stock of literature from academic journals on APIs with their associated themes, frameworks, methodologies, publication outlets and level of analysis. The authors draw on a total of 104 articles from academic journals and conferences published from 2010 to 2018. A systematic literature review was conducted on the selected articles. The findings suggest that API research is primarily a theoretical and largely focuses on the technological dimensions such as design and usage;thus, neglecting most of the social issues such as the business and managerial applications of APIs, which are equally important. Future research directions are provided concerning the gaps identified.

Neurosky MindWave headsets offer the possibility of using them in various software developments such as a Brain-Computer interface. However, these factory headsets only allow one connection for each device. This avoids the possibility of developing applications where two users each have to interact with their headset to the same computer at the same moment in time. Considering this aspect, the present investigation develops an application programming interface (API) for a Brain-Computer interface through the use of two Mindwave Neurosky headsets at the same time. The research designed and implemented a two-person attention game to test the operation of the two headsets. The results of the experiment were satisfactory since the API did not generate conflicts during the connection of both headsets, in addition the usability level of the application was cataloged by the users with 92.67 SUS points. In this way, the API allows applications to be developed that receive signals from two diadems.

When programmers use an API, they play the role of a "software user". As the quality of use of programs and systems affects productivity, more attention has been paid to API usability issues. This work focuses on another dimension of the quality of use, "communicability", which is characteristic of a semiotic approach. The paper presents a Semiotic Engineering study on the communicability of APIs. We analyzed metacommunication - a central concept of the theory we use between designers and users of date APIs, specifically, using the "SigniFYIng APIs" method. The results of the analysis were then related to the testimony of professional programmers during an interview concerning their experience with APIs and programming in general. We illustrate and discuss the value of the results achieved with our API communicability analysis, which in our view is a promising addition to research initiatives that have been exploring API usability.
