research design book

Preface: Immersed in the work at the beginning of the key items, almost forget to write articles, ashamed. Sharing is learning, without sharing there is no opportunity to learn, 2013 should continue to write more. At the same time also summed up 2012 years of writing, found that many times I am interested in various articles, phenomena, writing design notes and thinking. Sometimes thinking all kinds of things, and not summed up to be very practical. L

Some people need to design pages, but there is no design background at all, or there is no formal training in design. This book is exactly for these people. I. Design Principles: Contract is responsible for shuffling the fate, but we play cards on our own! Avoid too

At the beginning of the holiday, I started to look at the big talk design model. Now I have read about half of the book, and I have a vague feeling about the design model. His role is self-evident. Through the conversation in the book, and the continuous improvement of one example, using different models to makeCodeIt

A good program has a public standard called high cohesion and low coupling. However, this is a matter of degree. The high cohesion cannot avoid communication and communication, and it is abstracted blindly, inheritance is unscientific. We should look for a better solution. In this kind of design model, our predecessors have already paved the way for us. Structure? What is a structure? It is a load-bearing part of the building, which means a skeleton.

- 设置关注变量 - 18.9 detection system 18.9.1 using UID as selection criteria if (current->uid! = 7777) { / old algorithm / Else { / New Algorithm / } 18.9.2 Using condition variables You can use conditional variables if your code is not process-independent, or if you want to have a mechanism that can be used for all situations to control an attribute. This is easier than using UID, just to create a global variable as a conditional selector

product success Indicators: Product designer settingsWhether the D3 caused the task to failSecond, the key data to be concerned about:Ease of learning: first use success rate; puzzles need help times (users ask or find help themselves); Number of occurrences of a single userOperational efficiency (baseline required): time, number of operations Of course, this is only a framework, the weight, indicators and other applications need to be refined, in the attitude of

Simulation of I2C bus multi-master communication research and Software Design Author:■ Zheng Xuyang, Xi'an University of electronic science and technology, Li Bingbing, Huang Xinping Abstract:This paper introduces the principle of multi-master communication simulating I2C bus, and proposes a new implementation method. This method uses delayed receiving comparison to implement arbitration, so that common Mic

Article Description: Navigation Changes-Mobile site navigation design. Navigation is one of the most important parts of Internet website, it involves the information architecture, page layout and user interaction behavior of the product. The advantages and disadvantages of a website user experience are often closely related to the advantages and disadvantages of navigation. With the development of mobile Internet, more and more Web sites a

for this survey of the elevator, we need to understand how the elevator operates, the speed, the time between the switch door, and the maximum weight that the elevator can bear. (1) Purpose:Design and implement an elevator scheduling algorithm. Training skills: Requirements analysis, high-level design, design documentation, algorithmic design.(2) Demand analysis:

feature points, intercept the area of interest, reduce the number of redundant images to bring the calculation. At the same time, combined with concrete practical application, in the calibrated binocular vision camera, the rotation and scale transformation of the left and right images is small, so it can reduce the layer of image pyramid in the image scale space of sift algorithm. 4. System composition Mainly using the research results of senior labo

Primitive. C # has a basic type such as string, that is, primitive support. In fact, it is advantageous and harmful to not provide primitive support for a specific function. if your language is a common programming language and you want to apply it to as many fields as possible, you need to do less primitive support. however, if you only want to target a specific domain, you must provide many primitive support for this domain. for example, Matlab provides a lot of primitive support for mathemat
