Multi Level Cell (MLC) Phase Change Memory (PCM) is an enhancement of PCM technology, which provides higher capacity by allowing multiple digital bits to be stored in a single PCM cell. However, the retention time of MLC PCM is limited by the resistance drift problem and refresh operations are required. Previous work shows that there exists a trade-off between write latency and retention—a write scheme...
Condition based maintenance (CBM) is considered to be the most effective maintenance strategy in a performance contract. It significantly increases the system availability and efficiency, meanwhile reduces service affecting faults and maintenance cost, especially when combined with online monitoring of real-time condition data of assets. For the above reasons, CBM has been paid more attention in railway...
To avoid the frequent electric vehicle theft and traffic accident problems, a kind of electric vehicles real-time condition monitoring system based on Internet of things is introduced in this paper. The hardware system is built by the module integrated with GSM communication module and GPS chip, the ADXL345 three-axis digital acceleration sensor and the PIC16F1823 single-chip microcomputer control...
The management of electricity system in home environments plays an important role in managing energy consumption and improving efficiency of energy usage. At present, nonintrusive appliance load monitoring (NIALM) techniques are the most effective approach for estimating the electrical power consumption of individual appliances. This paper presents our contributions in intelligent electrical appliance...
Home electrical power monitoring plays an important role in reducing energy usage, and non-intrusive appliance load monitoring (NIALM) techniques are the most effective approach for estimating the electrical power consumption of individual appliances. Power load events detection is one of the most important steps in these techniques. This paper presents an automatic power load event detection method:...
Monitoring household electrical consumption by employing appropriate techniques is of great significance to sustainable development of human society. This paper proposes one approach of nonintrusive appliance load monitoring (NIALM) for electrical consumption managing. This approach can automatically monitor the house power consumption of individual devices. It employs multiple-class support vector...
There are mainly two classes of approaches in power disaggregation, including Intrusive Load Monitoring (ILM) and Nonintrusive Load Monitoring (NILM). This paper presents the literature review on the NILM approaches. NILM is a process for detecting changes in the voltage and current going through a house, deducing what appliances are used in the house, as well as their individual energy consumption,...
