Antenna design principle

resources to the development of Microstrip antennas, in the past there have been a number of studies around the application of microstrip antennas and theoretical analysis, but also has the relevant experimental equipment can be used for the development and design of microstrip antennas, for the development of electronic label antenna has a considerable basis. T

research. And this method is in Europe and the United States than the first to be used by multinational companies in new areas of research. Hope to explore their potential needs from the user's perspective and daily life to guide the design. Participate in the user's life, observe them, to understand the user, to meet their needs. The designer is more need to use "other people's eyes" to treat the things designed to study, that is, as a user, partici

of name in addition to using the Sayname () method. You can use the secure person constructor as below.var friend = person ("Nicholas", "Software Engineer");Friend.sayname (); "Nicholas"In this way, the variable friend holds a secure object, and in addition to calling the Sayname () method, there is no other way to access its data members. Even if other code adds methods or data members to the object, there is no way to access the raw data passed into the constructor. This security provided by

User experience: About design theory and design terminology

Web page Production WEBJX article introduction: about design theory and design terminology. The work of these days involves a lot of meetings. Also involves a lot of people, a lot of opinions, a lot of collisions, a lot of speculation. No more about the project itself, nor is it suitable for sharing at the moment. There are some digression, although

Analog circuit design: The myth of Theory and the reality of cruelty

system and the mode of the person should be able to understand, do not do analysis here). In fact, such circuits often do not work because of the non-ideal characteristics of op amp and other devices. Even the most basic wires have resistors, and theoretical analysis makes it difficult to consider so many non-ideal factors. In fact, it is generally necessary to add a few more devices, such as.

User Experience Design theory: Aspects of user experience design

use their own experience or the results of the market to prevail. In contrast, users-centric designers who communicate directly with potential users to learn more about their personal experience are more likely to show users ' needs than the statistical data on their research reports. In fact, what people tell market researchers is not necessarily consistent with the real situation (if you look at it). Many complete projects, in the later part of the concept Drill-down (concept develop), invol

Software Engineering--object-oriented design of theory, method and practice

Software Engineering--the design of the face object of theory, method and practiceIn the phase of object analysis, it is necessary to focus on what the system does, while in the design phase, it will focus on the software implementation of the system, including architecture design

Design theory: The professional problem of designers

powerful technical skills behind it is to help designers more dare to think, dare to create. So in addition to the theory, design skills training is equally important, a designer can not learn all the software, all the production process, this part of the team through the members of each other to each other-the premise is that the team must develop a frank, sharing spirit. 5. Face Customer Experience : Th

Software Engineering--object-oriented design of theory, method and practice

We focus on what the system is doing, and in the design phase we will focus on the software implementation issues of the system, including architecture design, detailed design, user interface design and database design.As with modeling, design is also a modeling activity tha

Domain model of field-driven design theory learning notes

2007 Eric Evans published "Domain driven design" so far, the concept of domain driven designs (Ddd:domain-driven design) has become increasingly understood and used. I have been a post-conscious, but it is not too late to mend. We are very familiar with the word domain, and often put it on the mouth, but how much value it? Developers are more focused on technology, and I actually want to study the DDD-based

Distributed system and Cap theory analysis under Linux

already cover most of the distributed storage systems.In fact, for large-scale distributed systems, the CAP is very stable, can be expanded in a few places.It largely limits the capacity for large-scale computing, and some design approaches to bypassing cap-governed areas may be key to the next large-scale system design.As you can see, these schemes always need to be sacrificed to another part of the package, and cannot reach the 100% cap. Which opti
