It is an emerging area of inter-disciplinary research between people in the electrical engineering, computer science, and among their various disciplines Sensors is a peer-refereed scientific journal on the science and technology of physical/chemical sensors and biosensors.
They do so using the minimum energy needed to reach the cluster head, and only need to keep their radios on during their time slot. 3 Improved LEACH Clustering Algorithm and Experiments A sensor network normally constitutes a wireless ad-hoc network, meaning that each sensor supports a multi-hop routing algorithm (several nodes may forward data packets to the base station).In computer science and telecommunications, wireless sensor networks are an active research area with numerous workshops and conferences arranged each year.
WINS networks provide sensing, local control, and embedded intelligent systems in structures, materials, and environments.

Due to interface and reaction between different materials, the occurrence of a double layer and diffusion layer becomes evident.
For capacitance, its value relates to material, geometric structure, and formation methods.
The bottom layer of conductive and nonconductive materials respectively prolonged or speeded the ion exchange between conductor fibres and electrolyte to influences characteristics of textile electrodes.

For this result, it is required that the utilization factor of shot-hole length be high in tunnel blasting so that a full use of blasting materials are made; that the broken rock blocks be equal in size and the block pile be reasonable in shape and range so that the broken stones are mucked easily; and that a smooth tunnel silhouette be produced so that tunnel supporting is completed quickly and economically.
Blasting material consumption.
It is obvious in this paper that material consumption is not an independent factor to be considered.

Indentation method refers to using a head of small contact surface to compress on a material of larger surface in a particular way.
And then that method measures the elastic of parameters of the test material.
The third common method is a hybrid structure model (mixture model), which regards the organization as a mixture of the different types of materials.
Omata and Terunuma proved that the resonant frequency will change when the sensor which is made of piezoelectric material contacts different materials[26].
