Unlike the partitioning and hierarchical clustering methods, it defines clusters as the largest set of points connected by density, can divide the areas with sufficient density into clusters,

0 IntroductionThe maturation and development of GPS technology provide a powerful guarantee for the precise and real-time positioning of all kinds of moving vectors. such as the use of GPs to the vehicle or ship navigation and monitoring [2]. At the same time, with the development of information technology, the size of PDA becomes more and more compact, and the function of integration becomes more and more powerful. PDA is moving toward computing, communication, networking, storage, entertainmen

1. Work Summary Recently, the IEEE is working on a new project the project is to develop a standard for the operation of Gigabit Ethernet (10GbE) transmission based on the current copper structured cabling system, which is collaborating with leading experts from integrated wiring, electrical, test equipment and system design, Panduit belong to one of the leading ranks, we have foreseen that with the future increase in transmission rate, cable and conn

---restore content starts---Image-based Wavefront sensing is a method to measure wavefront error by using parametric physical model and nonlinear optimization to calculate point diffusion function (PSF). When performing image-based wavefront sensing, a PSF is captured on the detector, and the physical model creates a wave front that generates an analog PSF that matches the optimized data. A good strategy is

). In an asymmetric frequency band, the uplink/downlink frequency is allocated according to the data traffic, and TD-SCDMA can optimize the air interface capacity so as to make more efficient use of the spectrum resources.From another perspective, growing bandwidth requirements and the diversity of wireless technologies require a flexible, manageable network architecture that meets the growing needs of operators. In addition, highly personalized services and services that rely on commercial and

Summary The ADF (Application Development Framework) is a solution specifically developed by Oracle to simplify the development of Java EE Programs and is the next-generation enterprise application Development framework provided by Oracle.At the same time, Oracle ADF is one of the most important technologies in fusion architecture and the core technology of fusion application, and almost all of Oracle's future products will be transferred to the ADF framew

1, Java full-text search engine Framework LuceneThere is no doubt that Lucene is currently the most popular Java full-text search framework, which, to be precise, is a full-text retrieval engine architecture that provides a complete query engine and indexing engine, some text analysis engines. Lucene provides developers with a fairly complete toolkit that makes it easy to implement powerful full-text retrieval capabilities. There are several search engine frameworks are also

If you need to retrieve data with latitude and longitude, such as finding a hotel 1000 meters near the current location, an easy way is to get all the hotel data in the database, calculate the distance by latitude, and return the data that is less than 1000 meters away. This is useful when the data is small, but the efficiency of the retrieval is low when the volume of data is large, and this article describes the use of SOLR's spatial query for spatial search. The principle of space search Spac

Recently research Gearman found a lot of problems, about the problem of queue persistence for half a month or not to solve, and domestic can reference too little information, so consider changing a plan to try. The architecture of the Gearman cluster is posted as follows:You can see the problem with this schema, and when persistence does not work, it can only be done by multiple jobserver running simultaneously to ensure the normal operation of the cluster. In addition the client and worker this

In the previous sections, we have covered what is target detection and how to detect targets, as well as the concepts of sliding windows, bounding box, and IOU, non-maxima suppression.Here will summarize the current target detection research results, and several classical target detection algorithms to summarize, this article is based on deep learning target detection, in the following sections, will be specific to each method.Before the rise of targe

1 Positioning Background Introductionwhen it comes to positioning everyone will think of GPs, but GPS positioning is slow for the first time (specifically can refer to the previous blog post "lbs positioning technology"), indoor can not use, power and other defects, these defects greatly limited the use of GPs. In most mobile internet applications such as Google Maps, Baidu maps, etc. , often based on WiFi, base station to locate. The General app wil

type variable--infer real data type based on initial valueIn the previous chapters, we covered a variety of data types in C + +: int types that represent integers, float types that represent floating-point numbers, and char types that represent a single character, as well as string types that represent strings. These data types, which are different in purpose, provide a rich choice for us to define variables to represent real-world data. However, the

web| Cache | design For a Web site with a daily visit to millions, the speed is quickly becoming a bottleneck. In addition to optimizing the application of the content publishing system itself, if you can not need real-time update of the dynamic page output to the static page to publish, the speed of the promotion will be significant, because a dynamic page speed is often slower than static pages 2-10 times, and static Web content if can be cached in memory, The speed of access will be even more

For us, the registers are familiar, and most of the x86 and arm directives we are familiar with. So based on what the stack is. In fact, based on the stack for some resource-scarce equipment (set-top box, embedded) more use. The JVM is based on the stack because the Java design idea is to run both on the server and in the embedded device (Java ME), because the st
