In this paper, we give an overview of the power line communication (PLC) technology. This paper presents an overview of the research, applications, standards and importance of the power line communication. Power line communication is an emerging home network technology that allows consumers to use their already existing wiring system to connect home appliances to each other and to the Internet....

Wireless sensor nodes may have power requirements as low as microwatts, and while batteries suitable for such applications may have lifetimes in years, inexhaustible supplies which scavenge energy provide an interesting alternative. This paper reviews the approaches to powering micro-sensor nodes.

This paper presents techniques derived from empirical modelling methods and especially designed to tackle the recognition of dynamic transients with the aim of detecting and diagnosing faults and anomalies in equipment and processes. Applications and results are also presented, covering BWR and PWR plants and spanning from component level diagnostic applications to sub-system and plant level di...

For vibration testing, discrete types of scanning laser Doppler vibrometer (SLDV) have been developed and have proven to be very useful. For complex structures, however, SLDV takes considerable time to scan the surface of structures and require large amounts of data storage. To overcome these problems, a continuous scan was introduced as an alternative. In this continuous method, the Chebyshev ...

With the development of new generation technology and the low-carbon economy, the smart low-carbon city has become one of the academic hotspots. Many studies on it have begun; however, the dynamic mechanism is rarely involved. Therefore, this paper uses the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method to creatively take a quantitative study on a Chinese smar...

Manipulating the flow of energy in nanoscale and molecular photonic devices is of both fundamental interest and central importance for applications in light energy harvesting optoelectronics. Under erratic solar irradiance conditions, unregulated power fluctuations in a light-harvesting photocell lead to inefficient energy storage in conventional solar cells and potentially fatal oxidative dama...

Abstract. Mechanical efficiency analysis is a fundamental phase in the design of Power Gear Trains (PGTs) transmissions. This paper presents a methodology for computing the mechanical efficiency of Epicyclic Gear Trains (EGTs). A novel feature of this methodology is the capability to take into account load dependent power losses and inertia effects. Finally, the paper describes an apparatus use...

We present the redesign and improved performance of the laser terahertz emission microscope (LTEM), which is a potential tool for locating electrical failures in integrated circuits. The LTEM produces an image of the THz waves emitted when the circuit is irradiated by a femtosecond laser; the amplitude of the THz emission is proportional to the local electric field. By redesigning the optical s...

The use of therapeutic low-level laser has become widespread in veterinary medicine. A number of illnesses and physical conditions are reported to respond to laser therapy (photobiomodulation.) There is support in the scientific literature for many of the physiologic effects claimed by proponents of laser therapy at the biochemical level. At the level of the organism however, there is still sig...
