Research of mine-used radar material level monitoring device
In view of shortcomings of bad anti-interference and low reliability existed in ultrasonic measurement method for coal level measurement, a mine-used radar material level monitoring device was designed. The device transmits high frequency electromagnetic

Sharp thresholds in adaptive random graph processes
AbstractThe ‐process is a single player game in which the player is initially presented the empty graph on vertices. In each step, a subset of edges is independently sampled according to a distribution . The player then selects one edge from , and adds to its current graph.

On identification of the threshold diffusion processes [PDF]
We consider the problems of parameter estimation for several models of threshold ergodic diffusion processes in the asymptotics of large samples. These models are the direct continuous time analogues of the well-known in time series analysis threshold autoregressive (TAR) models.

Denoising Method of dbN Wavelet Threshold for Die Repair Hammer Force Signals
In order to solve the problem that the noise of the hammer power signal in mold repair is large, the dbN wavelet (abbreviation of Daubechies, N is the wavelet order) is used to reconstruct the hammer force signal according to the obtained low frequency ...

Tactile and proprioceptive temporal discrimination are impaired in functional tremor. [PDF]
In order to obtain further information on the pathophysiology of functional tremor, we assessed tactile discrimination threshold and proprioceptive temporal discrimination motor threshold values in 11 patients with functional tremor, 11 age- and sex ...

Branching Process Approach for 2-Sat Thresholds [PDF]
It is well known that, as n tends to ∞, the probability of satisfiability for a random 2-SAT formula on n variables, where each clause occurs independently with probability α / 2n, exhibits a sharp threshold at α = 1. We study a more general 2-SAT model in which each clause occurs independently but with probability αi / 2n, where i ∈ {0, 1, 2} is the ...

The User Participation Incentive Mechanism of Mobile Crowdsensing Network Based on User Threshold
Mobile crowdsensing (MCS) network means completing large-scale and complex sensing tasks in virtue of the mobile devices of ordinary users. Therefore, sufficient user participation plays a basic role in MCS.

Extremes of autoregressive threshold processes [PDF]
In this paper we study the tail and the extremal behaviors of stationary solutions of threshold autoregressive (TAR) models. It is shown that a regularly varying noise sequence leads in general to only an O-regularly varying tail of the stationary solution. Under further conditions on the partition, it is shown however that TAR(

Optic cup segmentation using adaptive threshold and morphological image processing
Glaucoma is a chronic optic neuropathy. It was predicted that people with bilateral blindness caused by glaucoma will increase each year. Hence, computer-aided diagnosis of glaucoma was proposed to assist ophthalmologist to conduct a fast and accurate ...
