What Is Prototype Based Programming

Research and design of medical monitoring system based on ZigBee Kunming University of Technology Wang Mingwei This paper designs a prototype of medical monitoring system based on wireless sensor network of ZigBee technology. This system realizes the wireless transmission of the data, and develops the PC software on the monitoring base station, can read the simulated physiological data, analyze, store and display. This paper first through the Shenzhen Fei-CC2530MDK Technology Co., Ltd. production of the ZigBee development Kit, on the basis of Z-stack protocol stack, through the coordinator to establish a network, the use of terminal sensing ...

O42A is an advanced general-purpose programming language. It supports compilation, static type, prototype based, logic driven, and also supports imperative programming style. O42A writes a program that is much closer to the nature of English text than any C programming language, whose language design and programming efficiency and maintainability of the code are the main priorities, and it implements powerful, restricted, semantic, expressive, and natural syntax. O42A 0.1.7 This version updates the semantics of the sentence and makes it clearer. It is now equally possible to evaluate statements and imperative sentences. Some grammatical structures were dismantled. "Unknown" logic ...

Design and implementation of recommendation system based on Hadoop Tangjin The main work contents are as follows: 1. Based on the research of the running mechanism of Hadoop and the principle of MapReduce programming, combined with recommendation system and recommendation algorithm, especially the network recommendation algorithm represented by the material diffusion recommendation algorithm and the heat conduction recommendation algorithm, the paper designs and realizes the MapReduce programming scheme of network recommendation algorithm, The complex computing task of this algorithm is decomposed into a series of mapreduce operation Flow, ...

Design and implementation of remote fault Diagnosis Center for equipment based on Cloud Engineering Nanjing University of Goeling This paper studies the theory of cloud computing, characteristics and key technologies, combined with the above problems, the concept of "fault diagnosis Cloud" is introduced, and the storage and calculation of enterprise equipment fault data are concentrated in "cloud". This paper designs a b/c (brower/cloud-center) architecture Remote fault diagnosis system (relative to the traditional C/s and b/s), and expounds the overall composition and working principle of the system. And in the open source cloud computing flat ...

Doctoral thesis-Research and study on the key technology of the land Resource service efficient processing platform based on cloud computing the research work of Zhejiang University Fang Reiwenben mainly includes the following aspects: 1.

Translation: Esri Lucas The first paper on the Spark framework published by Matei, from the University of California, AMP Lab, is limited to my English proficiency, so there must be a lot of mistakes in translation, please find the wrong direct contact with me, thanks. (in parentheses, the italic part is my own interpretation) Summary: MapReduce and its various variants, conducted on a commercial cluster on a large scale ...

MapReduce: Simple data processing on large cluster

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

Cloud computing "turned out" so many people see it as a new technology, but in fact its prototype has been for many years, only in recent years began to make relatively rapid development. To be exact, cloud computing is the product of large-scale distributed computing technology and the evolution of its supporting business model, and its development depends on virtualization, distributed data storage, data management, programming mode, information security and other technologies, and the common development of products. In recent years, the evolution of business models such as trusteeship, post-billing and on-demand delivery has also accelerated the transition to the cloud computing market. Cloud computing not only changes the way information is delivered ...

Why is there interaction design, what can interaction design do? ▎1. What are the elements of a successful internet product? ① when your boss needs to make a product, it must first be achievable, which is why the core programmer architects are generally highly treated because they are productive. Then the successful product first has to have – the achievable model. What do ② products do? "User-friendly, let users play cool?" "Of course not, the ultimate goal of the product is profitability, and your leadership is only concerned about this." How to be profitable and sustainable. This requires a second ...
