Background: Modern day software applications involve management and processing of huge amount of data, originating from a variety of sources such as Internet of Things. Such data may be dynamic, homogenous or heterogeneous. Such data is processed by the users according to their own specific needs through programming code. The coding tool should be such that it is extensible and appropriate to manage such data. Th Read More

Background: The fly ash produced by coal-fired power plants is an industrial waste. The environmental pollution problems caused by fly ash have been widely of public environmental concern. As a waste of recoverable resources, it can be used in the field of building materials, agricultural fertilizers, environmental materials, new materials, etc. Unburned carbon content in fly ash has an influence on the performance of reso Read More

Background: The mounting growth of wireless technology is attracting a high demand for the frequency spectrum. The measurements of spectrum usage depict that a significant portion of the spectrum lays unoccupied or overcrowded. The main cause of the glitch is the existing inefficient and fixed scheme of spectral allocation. Cognitive radio is one such technology that permits wireless devices to detect the unused frequency Read More

Background: Signal generator plays a crucial role in the field of automatic measurement. However, Domestic signal generator usually uses a number of discrete phases locked loop components, whose circuits are usually complex with low precision and are easily affected by the external environment. Objective: Based on direct digital synthesis (DDS) technology, a small sized high precision economic waveform generator Read More

Background: The need for a diagnosis today, becomes a necessity for variable speed AC drives in several industrial applications. An important research axis is oriented towards monitoring the state of the converter supplying the electric motor. Indeed, the voltage source inverter is likely to have switching faults. Therefore, an emergency stop of the motor drive must be done. Objective: After reviewing related patents and w Read More

It has the characteristics of a wide variety of recipes, strong adaptability, wide transmission channels and serious harm, which seriously endanger the sustainable development of the ecological environment. At present, the control methods of the Hyphantria cunea are costly and inefficient. Objective: An intelligent target spraying robot based on machine visi Read More

Background: Vehicle centroid height is an important parameter in vehicle control systems. It plays an important role in vehicle roll stability and handling stability. At present, there are mainly static and dynamic measurement methods such as swing method, mass reaction method, marking method and so on. These static measurement methods often require a fixed suspension to make the measurement process time-consu Read More

Background: There has been an increasing interest in the soft pneumatic networks (also referred to as pneu-nets) actuators for soft robotics due to their innate softness, ease of fabrication and high customizability. More and more structures of the soft pneu-nets actuators are reported in various relevant patents and papers. The bending ability of soft pneu-nets actuator is one of the key characterizing performances. It is characte Read More

Background: Axial-flux permanent magnet synchronous generators (AFDS PMSG) have been found suitable in wind energy conversion system and electric vehicle owing to its compactness, high torque capability at low speed, high torque to inertia ratio, modular geometry, and high magnet usability index. Such applications require the generator to operate in Extended Speed Range (ESR). In ESR, voltage regulation is achieve Read More
