Mine Hoist

The real-time respondent speed and the reliability play a deciding role on the performance of the digital monitoring for mine hoist. Differs to the traditional monitoring for mine hoist , it is possible to improve the signal respondent speed during upgrading of mine hoist by two methods, one is to adopt the quick microprocessor and another is the embedded real-time multi-task operating system. The Advanced Reduced Instruction Set Computer Machines (ARM) is particularly suitable to work as the controller of the digital monitoring for mine hoist with its merits as high running speed and complete peripheral equipments. The micro C/OS-Ⅱcan both improve the respondent speed against various signals from mining enterprises fields and the reliability of the controlling software as an embedded real-time operating system.The principle of task allocation is an important one of the highest priority related to the stability of mine hoist and functional tasks. To avoid multiple tasks simultaneously access the same shared resources, two semaphores are introduced to determine the access mechanism of the shared resource. Application of real-time operating system is the future of digital development of mine hoist.

Abstract BackgroundRemote monitoring of mean arterial blood pressure (MAP), heart rate (HR) or oxygen saturation (SpO2) remains a challenge in outpatient surgery. This study evaluates a new digital technology (SmartAngelTM) for remotely monitoring hemodynamic data in real time.Methods Adults scheduled for elective outpatient surgery were prospectively enrolled. In the first 5 postoperative days, patients used a tablet three times a day to complete a self-report questionnaire (pain, comfort, nausea, vomiting) and two wireless Bluetooth monitors (oximetry for SpO2 and HR; MAP) connected to a 4G tablet that transmits data to a website, in real time, using SmartAngelTM software. Before transmission to the website, these data were also self-reported by the patient on a paper basis. The primary endpoint was the number of data recorded in the website using the app compared to paper basis. A system usability scale survey (SUS; score 1-100) was performed at day 5.Results From May 2018 to September 2018, data were available for 29 out of 30 enrolled (1 patient failed to discharge at home after surgery). The paper-basis recorded 2656 (82%) data versus 2038 (62%) for the remote monitoring technology (p=0.001). The most common errors with the remote technology were software malfunctioning when starting the MAP monitor and malfunctioning between the tablet and Bluetooth monitor. No serious adverse events were noted. SUS score was 85 (68-93) for 26 patients.ConclusionThis work evaluates the ability of a pilot system to monitor remote physiological data using digital technology after ambulatory surgery and highlights the digital limitations of this technology. Technological improvement is needed in order to reduce malfunction (4G access, transmission between apps).Trial registration: ClinicalTrials.gov (NCT03464721)(March 8, 2018)

Missed Opportunity

Abstract Cleanouts and milling make up most of the common coiled tubing (CT) operations around the globe. The objective of each is to remove debris from a wellbore, such as sand, scale, cement, or fracture plugs, to promote an unobstructed flow path for fluids. For decades, operators and service companies have focused heavily on methods to optimize removal of debris through the development of specialized tools, fluids, techniques, and predictive models. These are coupled with wellsite equipment digital acquisition systems to capture CT behavior, pump rates, and chemical additive rates; very little attention has been given to the rates of the fluid and solids being returned to surface. The composition and quality of fluids being pumped into the well are often well characterized, and the pump rate is recorded digitally to the second. By contrast, information on the fluid being returned is frequently limited to intermittent, manual surveys of the flowback tank fluid level that often go unrecorded. Fluid samples are rarely analyzed, even by inexact measurements, to provide feedback to the predictive model. This results in a missed opportunity to optimize the operation as well as to recognize and respond to undesirable trends and actions in real time. This paper describes a simple digital acquisition system developed and implemented in the field to digitally record, plot, and monitor critical wellsite parameters including flowback rate, solids returns, annular velocities, and downhole Reynolds numbers. The system provides a real-time visual aid to observe the direct impact that operational decisions have on cleanout efficiency and the opportunity to correct and optimize the cleanout operation. Furthermore, the system offers the opportunity to rapidly recognize and respond to unexpected trends such as a gradual or sudden loss in return rate or a decrease of solids returns which could rapidly result in serious consequences such as a stuck-pipe situation.

With the rapid development of science technology, to realize digital monitoring in the complex working conditions, the use of artificial intelligence machine to quickly achieve control operations. However, in the artificial intelligence system process, there may be a programmable datas inaccuracy and non real time, thereby to bring the certain error of control system that affects people's judgment. In programming data acquisition processing system, to introduce CBR diagnosis technique application, existing programming data acquisition processing system carries on fault coupling analysis. Through the data programming module transform for real-time diagnosis module, using artificial intelligence carries on automatic diagnosis for programming data, thus effectively solving the deviation in programming data acquisition process.

Quiescent Prominence

This paper describes some recent results of our quiescent prominence spectrometry program at the Mees Solar Observatory on Haleakala. The observations were made with the 25 cm coronagraph/coudé spectrograph system using a silicon vidicon detector. This detector consists of 500 contiguous channels covering approximately 6 or 80 Å, depending on the grating used. The instrument is interfaced to the Observatory’s PDP 11/45 computer system, and has the important advantages of wide spectral response, linearity and signal-averaging with real-time display. Its principal drawback is the relatively small target size. For the present work, the aperture was about 3″ × 5″. Absolute intensity calibrations were made by measuring quiet regions near sun center.

Capture Techniques

We have employed cryoelectron microscopy to visualize events that occur during the freeze-drying of artificial membranes by employing real time video capture techniques. Artificial membranes or liposomes which are spherical structures within internal aqueous space are stabilized by water which provides the driving force for spontaneous self-assembly of these structures. Previous assays of damage to these structures which are induced by freeze drying reveal that the two principal deleterious events that occur are 1) fusion of liposomes and 2) leakage of contents trapped within the liposome [1]. In the past the only way to access these events was to examine the liposomes following the dehydration event. This technique allows the event to be monitored in real time as the liposomes destabilize and as water is sublimed at cryo temperatures in the vacuum of the microscope. The method by which liposomes are compromised by freeze-drying are largely unknown. This technique has shown that cryo-protectants such as glycerol and carbohydrates are able to maintain liposomal structure throughout the drying process.

Diffraction Patterns

Computer programs are now available in various laboratories for the indexing and simulation of transmission electron diffraction patterns. Although these programs address themselves to the solution of various aspects of the indexing and simulation process, the ultimate goal is to perform real time diffraction pattern analysis directly off of the imaging screen of the transmission electron microscope. The program to be described in this paper represents one step prior to real time analysis. It involves the combination of two programs, described in an earlier paper(l), into a single program for use on an interactive basis with a minicomputer. In our case, the minicomputer is an INTERDATA 70 equipped with a Tektronix 4010-1 graphical display terminal and hard copy unit.A simplified flow diagram of the combined program, written in Fortran IV, is shown in Figure 1. It consists of two programs INDEX and TEDP which index and simulate electron diffraction patterns respectively. The user has the option of choosing either the indexing or simulating aspects of the combined program.

And Control

Knowledge of material pseudodielectric functions at MBE growth temperatures is essential for achieving in-situ, real time growth control. This allows us to accurately monitor and control thicknesses of the layers during growth. Undesired effusion cell temperature fluctuations during growth can thus be compensated for in real-time by spectroscopic ellipsometry. The accuracy in determining pseudodielectric functions is increased if one does not require applying a structure model to correct for the presence of an unknown surface layer such as a native oxide. Performing these measurements in an MBE reactor on as-grown material gives us this advantage. Thus, a simple three phase model (vacuum/thin film/substrate) can be used to obtain thin film data without uncertainties arising from a surface oxide layer of unknown composition and temperature dependence.In this study, we obtain the pseudodielectric functions of MBE-grown AlAs from growth temperature (650°C) to room temperature (30°C). The profile of the wavelength-dependent function from the ellipsometry data indicated a rough surface after growth of 0.5 μm of AlAs at a substrate temperature of 600°C, which is typical for MBE-growth of GaAs.

Real Time Observation

Previous observations of magnetic flux-lines (vortex lattices) in superconductors, such as the field distribution of a flux-line, and flux-line dynamics activated by heat and current, have employed the high spatial resolution and magnetic sensitivity of electron holography. And recently, the 2-D static distribution of vortices was also observed by this technique. However, real-time observations of the vortex lattice, in spite of scientific and technological interest, have not been possible due to experimental difficulties. Here, we report the real-time observation of vortex lattices in a thin superconductor, by means of Lorentz microscopy using a 300 kV field emission electron microscope. This technique allows us to observe the dynamic motion of individual vortices and record the events on a VTR system.The experimental arrangement is shown in Fig. 1. A Nb thin film for transmission observation was prepared by chemical etching. The grain size of the film was increased by annealing, and single crystals were observed with a thickness of 50∼90 nm.
