Abstract As the core component of industrial robot RV reducer, its health condition determines life and accuracy robot. The main reason that restricts long-term stable operation robots. This paper analyzes compares advantages disadvantages various technologies from three aspects: state detection, signal processing fault diagnosis. problems developing real-time online evaluation are also discuss...

We deal with binary theta-joins in a MapReduce environment, and we make two contributions. First, we show that the best known algorithm to date for this problem can reach the optimal trade-o↵ between the size of the input a reducer can receive and the incurred communication cost when the join selectivity is high. Second, when the join selectivity is low, we present improvements upon the state-o...

To relieve the burden of reasoning on a point to point basis, in many domains there is a need to reduce large and noisy data sets into trends for qualitative reasoning. In this paper we propose and describe a new architectural design pattern called reducing large and noisy data sets that can be tailored for particular situations. REDUCER consists of 2 consecutive process which takes the origina...

Novel treatment of chornic graft-versus-host disease in mice using the ER stress reducer 4-phenylbutyric acid.

Nonlinear PAPR reducers, such as clipping and companding techniques, are some simple methods used to reduce the Peak-to-Average Power Ratio (PAPR). In this paper, assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, we investigate the PAPR distribution of an OFDM signal when it is passed through a nonlinear PAPR reducer. The obtained PAPR distribut...

The study of hysteresis can be traced back to the 19th century. key characteristics are rate independence and dependence. A typical system with is reducer. In industrial sector, phenomenon a reducer often illustrated by lost motion, which always consistent default. paper, hysteretic model considering geometric errors established. Theoretically, found mostly maintain dependence rather than indep...

The windowed synchronous averaging (WSA) is widely utilized for planetary structures. However, it cannot be applied the fault detection of structure in industrial robot rotate vector (RV) reducer. usually works within a specified angle range, which causes RV reducer rotates incompletely. To address this issue, an compensation local fitting scheme proposed. detect localized planet gear reducer, ...

Abstract This paper proposes a simple approach on the synthesis of 2D profiles for rotors cycloidal reducers. A rotor (or disc) profile (as complex closed curve) can be defined an alternative to strictly mathematical definition) as internal bordered envelope family stator ring gear) obtained with movable (for at least completely rotation) around fixed planetary by respecting gearing conditions ...
