Shaft guide is detected mainly by a static test method,but it need much time to detect and practical experience of the technical person for most of the mine.This paper designs a testing system based on matlab to solve this problem and introduces the system's survey principle.The dynamic parameters of shaft is measured by tilt sensors,acceleration transducer and displacement sensor separately,the relations between the shaft rigid's parameters and breakdown is analysed.The selection and design of hardware system is rational as well as software's function,the system has strong practicability.

Localization is a fundamental and essential issue for wireless sensor networks (WSNs).In this paper,we present a range-free region localization (RFRL) algorithm for static WSNs,in which each unknown node collects the location information of anchors within its two-hop distance,and then some location information of its one-hop anchors and two-hop anchors are chosen to implement a grid-scan algorithm.Analysis and simulation results show that our algorithm outperforms the other Grid-Scan schemes even when the communication radius is irregular.

The distributed optical fiber Raman sensor system was widely used for real-time measurement temperature,but the Anti-Stokes and Stokes scattering Raman signal is very weak.In order to improve measurement accuracy the signal must be denoised before obtaining the temperature.In this paper,a new noise cancellation of empirical mode decomposition is proposed for enhancing signal-to-noise ration of the Anti-Stokes and Stokes scattering Raman signal.The signal-to-noise ratio was enhanced by using this method and it is easy to be realized in computer.

This document describes the testing and evaluation of the Automated Optical Processing System (AOPS) version 4.8 for the Visible Infrared Imager Radiometer Suite (VIIRS) sensor. AOPS enables exploitation of multiple space-borne ocean color satellite sensors to provide optical conditions for operational Navy products supporting mine Warfare (MIW), Naval Special Warfare (NSW), expeditionary warfare (EXW), and antisubmarine warfare (ASW). Ocean optical products are used to predict the impact of the environment on diver operations, communications, mine detection, and target detection. As part of this evaluation, comparisons are made with existing operational satellite products from MOSIA- Aqua, in situ data from ocean cruises and comparison with the Aerosol Robotic Network-Ocean Color (AERONET-OC) SeaPrism sensors. These comparisons show that VIIRS generates high quality ocean color products and should provide a continued data stream to support operational products.

As the development of the society and economy,more and more cars are used in the people life.Parking the car in a busy mall is often frustrated for us due to lack of the parking spaces.The problems mainly consist of two aspects.First,when we go to the destination,we do not know where the parking lot is and how many parking spaces is free.We have to spend a lot of time to find a parking lot.Besides,the parking lot usually is great,it is difficult for us to find the free space efficiently.Traditional solutions are implemented based on the TCP/IP networks or sensor network.TCP/IP solutions often require a lot on the infrastructure.Solutions with sensor network can not navigate the driver precisely.In this paper,we propose a novel parking management system with RFID and sensor networks,which can not only detect and locate the free parking space quickly,but also navigate the car to the parking space effectively.Our experiment shows that the proposed system is desirable for us to use in the life.

Model search is a crucial component of data analytics pipelines, and this laborious process of choosing an appropriate learning algorithm and tuning its parameters remains a major obstacle in the widespread adoption of machine learning techniques. Recent effortsaiming to automate this process have assumed model training itself to be a black-box, thus limiting the effectiveness of such approaches on large-scale problems. In this work, we build upon these recent efforts. By inspecting the inner workings of model training and framing model search as bandit-like resource allocation problem, we present an integrated distributed system for model search that targets large-scale learning applications. We study the impact of our approach on a variety of datasets and demonstrate that our system, named GHOSTFACE, solves the model search problem with comparable accuracy as basic strategies but an order of magnitude faster. We further demonstrate that GHOSTFACE can scale to models trained on terabytes of data across hundreds of machines.
