topix feedback

-phase and reverse-phase connection problems. In fact, because the open-loop output phase is directly related to the port connection method, we have to consider it here. Then there is feedback, the signal processing circuit and the signal generation circuit.(3)The next step is negative feedback. I think this part of content is the most difficult and important. The main content is:

The adaptive query optimization in ORACLE12C is composed of a series of different characteristics. Like the Adaptive Planning (Adaptiveplans) feature, you can modify the execution plan at run time, but do not allow changes in the sequence of connections in the schedule. Automatic re-optimization is based on the learning of previous execution and feedback to the optimizer information, so the next time the statement is executed, a better plan will be ge

Usability studies show that users can be aware of the response time over a second. Although in the feedback system, when the user needs to wait, the better solution is to adopt a deterministic progress bar. But for some short time consuming, and the user's bandwidth is the main factor, but use loading this low cost implementation feedback. The historical origins of the loading icon have been impossible to

Ajax|rss| Advanced RSS aggregators are an application that is particularly suited for building with a standard AJAX engine, but it is often difficult to implement a Cross-domain Ajax request for RSS feeds. In this article, I'll show you how to use a simple PHP function to implement the "bridging" Ajax engine and RSS content. First, the introduction Now, developing an RSS aggregator is no longer a difficult task, but developing a high-quality RSS aggregator is still quite difficult. On the other

TB has recently been added to the user feedback portal in key product and shopping processes (Figure 1), and various official forums have been set up to collect user comments and suggestions, so a large amount of plain text data will be collected. How can these data be analyzed to guide product improvement? This article will describe the theoretical basis and practical application of content analysis for network text data (e.g., user

There are two types of notifications: General notifications and soliciting opinions.Users in the system are divided into three categories, with different users and different processing models.

I. Introduction Now, developing an RSS aggregator is no longer difficult, but developing a high-quality RSS aggregator is still quite difficult. On the other hand, it is generally not difficult to create a custom aggregator, And you can provide an interface of your choice in this aggregator. RSS aggregation represents a type of data that is especially suitable for consumption by an AJAX application, because it is in XML format and AJAX can display new feedba
