The ball screw nut is the key component in the ball screw pair. Because of its complex inner structure and small hole size, it is difficult to measure machined accuracy of the ball screw nut. A non-contact measurement method of the ball screw nut based on spectral confocal principle is presented. The measurement space of the cylindrical coordinate of the nut is established according to its structure features. The inner cavity is scanned by dividing the section layer by layer to obtain the three-dimensional point-cloud data of the inner surface. Through transferring measurement space of the cylindrical coordinate into the calculation space of the rectangular coordinate the structure parameters of the inner groove of the ball screw nut are calculated, including pitch, inner diameter, pitch diameter, median runout and lead angle. The chord height difference method is used to denoise and filter the measurement data to get the more actual measured data. The three-dimensional reconstruction of the nut cavity structure is carried out using reverse technology to display the processed textures. The feasibility and effectiveness of the method is verified by the measurement experiment of ball screw nut. The experimental results show that the measurement method proposed in this paper can effectively check the ball screw nut with the high measurement accuracy, and has the ability of wide measurement range, and good expansion.

With the developments in radar signal processing, it is more common that the received signals are the combinations of noncircular and circular ones. Some variations of MUSIC and ESPRIT have been developed to cope with the case. One typical method has been discussed in [F. Gao, A. Nallanathan, Y. Wang, “Improved MUSIC Under the Coexistence of Both Circular and Noncircular Sources”, IEEE TRANSACTIONS ON SIGNAL PROCESSING, vol.56, no. 7, pp.3033–3038], where all the sources are completely polarized (CP). In this correspondence, an algorithm named conjugate MUSIC is proposed to estimate the Direction-of-arrival (DOA) of partially polarized (PP) signals. Compared with the conventional MUSIC, the conjugated version improves the estimation accuracy by exploiting the noncircularity. Numerical examples show the effectiveness of the proposed method.

Cyclic redundancy check (CRC) plays a significant role in enhancing the safety and reliability of data transmission. To improve the check capacity of CRC, a rolling CRC algorithm that generates check data using two generator polynomials is proposed, which can eliminate the previous defects of high failure rate and resource consumption. Being applied in the test on high definition multimedia interface (HDMI), the result of implementation of the field programmable gate array (FPGA) shows that new algorithm can improve the check capacity on the basis of low logic complexity and thus ensure more reliable HDMI test. Experiments show that this algorithm is more effective and highly capable of detecting errors.

The purpose of the current study is to find a low-cost and rapid-fabrication approach for producing Thin-film thermocouples (TFTCs) with different junction thicknesses. Nowadays, the popular TFTC fabrication methods are usually based on physical vapour deposition technology. They are high time cost and poor economy. In order to improve the production efficiency, a modified screen printing technology which is combining with wet grinding technology was employed in this article. First, the uniform thickness Pt/Au TFTCs were fabricated based on the regular screen printing technology. Then, the different junction thickness TFTCs were obtained through polished by an automatic high precision lapping machine. With this step, the junction thickness of TFTC is no longer limited to the viscosity and fineness of the ink in the present method. Through the calibration experiments, the static and dynamic performance of the fabricated Pt/Au TFTCs were estimated. The results show that the Seebeck coefficient of these TFTCs have no significant degradation compared with wire-style thermocouples in the temperature from 50 °C to 620 °C. The repeatability and consistency of these TFTCs are satisfying the requirements of the wire-style thermocouples. The pulse laser heating experiments results show the response time constant of these TFTCs are less than 12.33 μΞ. Compared with other screen-printed TFTCs, the Pt/Au TFTC presented in this study has a wider temperature measurement range. This implied that this rapidly and economically fabricated TFTCs can satisfy the requirements in many transient surface temperature measurement applications.

In this paper, we reported the design and numerical simulation of multi direction jet flow generator with disc shaped multi circular airflow channel. Using the finite element analysis method, the COMSOL Multiphysics software was used to calculate the airflow field distribution and motion feature inside of the generator. Calculation and results indicated that: (1) There is an integrated, steadily cycled and directional flow inside of this device. (2) This generator produced four directional flow comprising two perpendicular pairs of flow and generated four orthometric distributed jet flow inside of sensing chamber. (3) The airflow velocity at pump chamber nozzle and sensing chamber nozzle are 20.84m/s, 12.52m/s, respectively. The velocity at the two nozzles are much higher than other part inside of the channel. The mentioned multi direction jet flow generator can be used in multi axis jet flow inertia sensor, micro fluid system and lab-on-chip and so on studying field.

Sea-sky-line is one of the most significant marine observation indexes. An algorithm using images of different grayscales to detect sea-sky-line is proposed in this paper. The image is divided into two layers by different pixel values between the strong water pattern and other elements such as the illumination and the clouds. Two lines are extracted through the Hough transform by two layers of the image. If the two lines can be recognized as one, we take the mean as the result; otherwise, we take the one with maximum variance. A test of sea images in complex weather conditions results in high accuracy.

Fault diagnosis is gaining interest both in academic and industry fields, which assures machinery operational safety and reliability in terms of electrical equipments such as servo actuator systems. With a view to design a desirable diagnosis method that can gain better generalization ability of fault diagnosis with limited labeled data, a novel fault diagnosis method that utilizes tri-training architecture based semi-supervised ensemble learning is proposed, where three base learners are established and trained iteratively to reinforce the learning process by exploiting unlabeled data plus few labeled data. Besides, given consideration to both accuracy and diversity, a data editing technique for unlabeled samples is used in this study for the purpose of augmenting the differentiation of the base classifiers, where kernel principle component analysis (KPCA) maps the self learnt samples into several label vectors to further select the subsets with greater diversity instead of all for the incremental training. The proposed method aims to facilitate fault identification ability adaptively by taking advantage of unlabeled samples, which is appropriate for dealing with the diagnosis issues that only limited number of labeled data exist. Comparative experiments are included in this paper to demonstrate the effectiveness in fault diagnosis of servo actuator systems.
