Abstract: In this paper, we propose a small-footprint wake- up-word speech recognition (WUWSR) system with two stages to recognize a two-syllable wake-up word. In the first stage, convolution neural network (CNN) is trained to predict the posterior probability of context-dependent state. Thus a wake-up-word is detected according to the confidence …

That's another common question that may be asked. That question is easier to answer. 2 stage crushing involves just 2 crushers in a crushing plant, i,e, a primary crusher and a secondary crusher. This is usually, although not always, a jaw crusher and a cone crusher. 3 stage crushing just means that there are 3 crushers within the …

Repetitive or cyclic rail loading deteriorates the engineering properties of the railway ballast by particle crushing and rearrangement. Most of the classical elasto-plastic models are unable to predict such ballast degradation despite successfully predicting the overall load–deformation behavior during cyclic densification. In this context, the present …

The present study evaluates the effects of three different stages of crushing mechanism, namely two stage (2S), three stage (3S) and four stage (4S) on various morphology parameters (i.e. angularity, texture, flatness & elongation, sphericity and form2D) of aggregates. The 2S crushing consisted of primary and secondary crushers …

After an intense fracturing phase in the elastoplastic stage, this behavior is followed by a hardening stage as the third stage in which finer grains resist to crush furthermore (Fig. 11). In the double-plate grain crushing test, a sufficient quantity of 16.00–19.00 mm sized dolomite single grains were crushed for certain vertical ...

One-stage crushing was carried out for outlet slot er = 11 mm, and two-stage crushing for er = 24 mm and 11 mm. In the tests special design of variable profile moving jaw was used and fixed jaw was flat. The analysis of the results shows that taking into account energy consumption, it is better to use two-stage crushing process. For given

Ballast is generally defined as a volume of graded crushed rocks, however many other materials have been used or developed to serve as ballast [1].It is typically laid in a compacted layer, generally 250–350 mm thick, as shown in Fig. 1.It has the following functions [1], [2], [3]:. Resistance to the sleepers against vertical, longitudinal and lateral …

Aquarius® UV is a ballast water management system, providing a safe, flexible and economical process for the treatment of ballast water. Ballast water treatment with the Aquarius® UV system is achieved through a simple and efficient two stage process. Upon uptake the sea water is first passed through a back washing filter (1st Stage).

The present study evaluates the effects of two different aggregate production (crushing) mechanism, i.e. Jaw-Horizontal Shaft Crusher (HSI) named as JH and Jaw-Jaw-HSI-Vertical Shaft Impact Crusher (VSI) known as JJHV on aggregate dimension distribution. Both crushing mechanisms represents wide range of crushers and stage of …

The crushing process is commonly conducted in several stages. Each stage of the crushing process implements a different type of crusher to gradually reduce the size of the material. The first step is crushing the material by using larger crushers that can reduce the material into smaller sizes that will be used in the next stage.
