Root cause analysis of the detected anomalies can be tedious and currently carried out mostly manually if at all in most practical cases, operators simply reset problematic cells. Moreover, it enabled us to capture the uncertainty associated with engine diagnosis, and to incorporate learning capabilities in the expert system.Īs the complexity of commercial cellular networks grows, there is an increasing need for automated methods detecting and diagnosing cells not only in complete outage but with degraded performance as well. Using Bayesian Networks simplified the modeling of the complex process of diagnosing HDDEs. This paper presents an easy to use expert system for diagnosing HDDE faults that is based on the Bayesian Network Technology. These tools are not able to recommend corrective action. In addition, most of them do not have the functionality that is required to assist inexperienced technicians to completely diagnose and repair HDDE faults, because most of the tools have only the capability to identify HDDE faults. Current computerized tools for diagnosing HDDEs are tied to particular manufacturer’s products. Because of their complexity, HDDEs require high expertise for the diagnosis of their faults such expertise is in many cases scarce, or just unavailable. It is necessary that diagnosis is done during both preventive maintenance and when the engine has failed. If you have something to add, tell us in the comments below.Heavy-Duty Diesel Engines (HDDEs) support critical and high cost services, thus failure of such engines can have serious economic and health impacts. An alternative Device Manager also exists for older Ubuntu versions. It is a great utility for accessing system information on Ubuntu operating system. It offers a highly detailed configuration data about the machine. Speccy by Piriform – the makers of CCleaner and Recuva – is the most popular system information tool for Windows operating system. But there are other important details about your system which are important and you should have an idea about them. Like, the processor model, amount of RAM, GPU model, operating system. Most of us mainly have a rough idea about our system. Recommended: What Does The Refresh Option In Windows Actually Do?

All you need to do it press the designated key at the time boot screen when you start your machine.įor example, I have a Dell laptop and I press F12 to access the diagnostics option. If your computer didn’t come with a preinstalled system testing software, then you can access the one present in the boot menu of your machine. Your computer manufacturer provides inbuilt diagnostic tools which you can use to detect any sort of hardware errors. Hardware Testing Utility in the Boot Menu They also put their home baked checking tools which you can use without any difficulty. Most manufacturers provide preinstalled OS, which is mostly Windows, in their machines. System Testing Software Provided By PC Manufacturer: Recommended: Windows 10 CPU Temperature: Fix And Monitor The Heat Issue All-In-One Computer Diagnostics Tools For Windows: Don’t do it if you don’t know much about it. Please gain enough knowledge about stress testing and the tool you’re using to do it (especially for the command line). Important: Stress testing utilities put extra load on your machine to test its stability. By ugly, I mean it works on the Ubuntu command line.įor the command line lovers, CPUburn is also a good stress testing utility. It’s an ugly looking brother of the Prime95. It is a CPU stress test tool designed to give a 3rd-degree torture to your processor.
