The efforts for more reliable power conversion systems have been gaining momentum in recent years. The majority of the studies concerning reliability of power switches focus on the package-related failures, mainly caused by the cyclic thermal stress. The basic failure precursor for this type of stress has been identified as increased on-state resistance for power MOSFETs in the recent literature....
This paper introduces software for a monitoring system of the industrial furnace based on the c# language. Server and client interfaces are implied on the Windows's. Form class. The communication between the server and the client is realized though the socket class, which is included in the .NET class library. Most of the commonly useful information can be demonstrated in our system, such as gas concentration...
This work investigated that the mechanical and electrical behavior of PZT disk stacks embedded in asphalt pavement using a finite element analysis program. The stacks were composed with PZT disks with different thickness and diameter and connected in parallel. At first, the displacement difference of pavement surface with and without transducer was studied. The nylon was selected to fabricate cylindrical...
This paper builds improved Stochastic Filtering Model (SFM) for Condition Based Maintenance (CBM) using covariates obtained from Dynamic Principal Component Analysis (DPCA) of oil data. DPCA covariates, derived from DPCA of the oil data, represent most of the variability in the original data with reduced dimension and little cross-correlation. This makes DPCA covariates ideal for maintenance modeling...
Distributed storage and prediction method of monitoring data for mooring monitoring system is researched. Aiming at the real time requirement of monitoring and prediction for mooring monitoring system, used Hadoop distributed file system to store generous monitoring data, and used Map/Reduce framework to predict monitoring data, which solve the problem of mass data storage in limited memory and time-consuming...
Aiming at the growing phenomenon of cheating in exams using radio-technology, the paper introduces a radio anti-cheat system. It monitors the frequency band occupied by cheating signal (voice signal mostly), and then fires interfering signals in the corresponding frequency band so as to achieve the purpose of suppressing the cheating signal. The performance of interfering signals is very important...
Service-level reuse development has drawn great attention in the research field of embedded systems. In this paper, we present reusable integrity management services for future embedded systems based on virtualization technique. A series of problems related with system security and reliability are addressed by adopting these services to existing system designs. Moreover, we have implemented the prototype...
This paper introduces a new dependable operating system project, called DEOS, started in 2006, and scheduled to continue for six years. In this project, a safety extension mechanism called P-Bus is to be designed, and implemented in the Linux kernel so that a future dependability attribute is implemented with P-Bus. A hardware abstraction layer, called SPUMONE, is introduced so that a light-weight...
The kernel objects consist of critical kernel data structures and system call functions, which are the most important data for a system, should be protected as first-class candidates. In this paper, a lightweight system-level detection and recovery infrastructure is presented for embedded systems. Inside the infrastructure, specific runtime protections have been implemented for different kernel objects,...
In this paper, a lightweight system level monitoring infrastructure known as kernel objects monitoring infrastructure (KOMI) is presented for commercial-off-the-shelf (COTS) embedded systems. The kernel objects consist of certain critical kernel data structures and entry points of system calls, which are protected as first-class objects inside the system. KOMI provides specific runtime protections...
