In recent years, flexible pressure sensing arrays applied in medical monitoring, human-machine interaction, and the Internet of Things have received a lot of attention for their excellent performance. Epidermal sensing arrays can enable the sensing of physiological information, pressure, and other information such as haptics, providing new avenues for the development of wearable devices. This paper reviews the recent research progress on epidermal flexible pressure sensing arrays. Firstly, the fantastic performance materials currently used to prepare flexible pressure sensing arrays are outlined in terms of substrate layer, electrode layer, and sensitive layer. In addition, the general fabrication processes of the materials are summarized, including three-dimensional (3D) printing, screen printing, and laser engraving. Subsequently, the electrode layer structures and sensitive layer microstructures used to further improve the performance design of sensing arrays are discussed based on the limitations of the materials. Furthermore, we present recent advances in the application of fantastic-performance epidermal flexible pressure sensing arrays and their integration with back-end circuits. Finally, the potential challenges and development prospects of flexible pressure sensing arrays are discussed in a comprehensive manner.

Saat ini, JavaScript banyak digunakan di dalam pengembangan website di sisi server (Back-End). Terdapat lima pilihan Back-End JavaScript framework yang umum digunakan, yaitu: Koa, Express, Plumier, Loopback, dan Nest. Pengembang perlu memilih framework mana yang memiliki performansi terbaik untuk dapat menghasilkan website dengan performansi terbaik. Untuk itu, di dalam penelitian ini, dilakukan pengujian perbandingan performansi terhadap kelima Back-End JavaScript framework pada protokol HTTP di dalam jaringan komputer dengan menggunakan metode GET dan POST. Pengukuran performansi menggunakan dua parameter penilaian, yaitu: 1.)Kemampuan framework di dalam menangani request per detik (dalam req/s), dan 2.)Penurunan kecepatan pemrosesan data (dalam %) terkait dengan parsing, validasi, routing, request. Masing-masing framework yang diujikan, dilengkapi dengan router, body parser, validator, NodeJS Package Manager (NPM). Pengujian dilakukan sepuluh kali pada GET dan POST, untuk kemudian diperoleh nilai rata-rata performansi dari setiap framework. Hasil pengujian menunjukkan bahwa Koa memiliki performansi terbaik dan Loopback memiliki performansi terburuk. Dari hasil penelitian ini, Koa, Express, dan Plumier, direkomendasikan untuk dipilih pengembang, jika dibandingkan dengan Nest dan Loopback.

By integrating the needs of each team, combining the previous development experience and the current mature development framework mode, this paper proposes to build a business account management and statistical report analysis system based on the front-end and back-end separation framework, which can be used by each team to improve work efficiency and enhance the reusability and practicality of various marketing data. This paper introduces the web directory structure of the whole system and the contents and related operations displayed on the corresponding management pages. For the needs and problems raised by users, the system adds corresponding functions and pages to solve them. The back-end of the marketing data management system is based on J2EE framework and developed by springboot+mybatis. The front-end is developed by react + ant design + node + echarts+ less.

We describe a single framework in which to view the end-to-end-independently-verifiable (E2E) polling-place voting systems with a mixnet back-end. We use the framework to invent new systems that combine front and back-ends from existing systems.

Libraries provide a complex set of information resources through their websites, which are often centered on their catalog or discovery services. Their collections are increasingly diverse, spanning physical and digital formats, and they provide a variety of tools for their users to explore and gain access to these collections. It can be quite a challenge to bring together all of the components on a website in a consistent presentational design and with unified content access. In many cases, the discovery service is powered by an entirely separate application from the website itself. This difference in back-end technologies can assert almost jarring differences in the way that patrons interact with the discovery service or catalog relative to the other aspects of the site. Other components, such as those that manage events, directories, or other specialized services, likewise impose their own user interface conventions.

In polypropylene petrochemical plants power adjustable speed drives (ASDs) are normally used to drive extruder or pump machines required by this type of industrial process. Each one of these ASDs is fed by a dedicated converter transformer which supplies a diode-front-end rectifier in the input converter part of the ASD. In case one diode of the input rectifier is faulted and becomes short-circuited, the converter transformer can be subjected to a dynamic short circuit stress being higher than that due to a fault occurring just at transformer terminals: this phenomenon is called diode arc-back fault in technical literature. Simulations are carried out by means of EMTPATP software in order to show the effect of diode arc-back fault on the dynamic peak short circuit currents to which transformer windings are exposed

Over the past few years, the computation capability of field-programmable gate arrays (FPGAs) has increased tremendously. This has led to the increase in the complexity of the designs implemented on FPGAs and to the time taken by the FPGA back-end flow. The FPGA back-end flow comprises of many steps, and routing is one of the most critical steps among them. Routing normally constitutes more than 50% of the total time taken by the back-end flow and an optimization at this step can lead to overall optimization of the back-end flow. In this work, we propose enhancements to the routing step by incorporating a reinforcement learning (RL)-based framework. In the proposed RL-based framework, we use the ?-greedy approach and customized reward functions to speed up the routing step while maintaining similar or better quality of results (QoR) as compared to the conventional negotiation-based congestion-driven routing solution. For experimentation, we use two sets of widely deployed, large heterogeneous benchmarks. Our results show that, for the RL-based framework, the ?-greedy greedy approach combined with a modified reward function gives better results as compared to purely greedy or exploratory approaches. Moreover, the incorporation of the proposed reward function in the RL-based framework and its comparison with a conventional routing algorithm shows that the proposed enhancement requires less routing time while giving similar or better QoR. On average, a speedup of 35% is recorded for the proposed routing enhancement as compared to negotiation-based congestion-driven routing solutions. Finally, the speedup of the routing step leads to an overall reduction in the execution time of the back-end flow of 25%.

In web development, it takes much time to code for back-end including business logic and interface integration, which is machanized and high-repeated. In order to address the problem in back-end web coding, this paper analyzes the advantages and disadvantages of SSM(Spring, SpringMVC and MyBatis) framework and development pattern of the original and end separation. By integrating the template engine in PHP web development, we achieve the technology of code generation for back-end of web, which benefits for artificial intelligence of web coding and saves the time on software engineering.
