As a general rule, data accuracy is reduced with increased punch speed.
In general, they require as input sheet thickness and material data.
Punch-Load data.
Press data and experimental conditions are summarized in Table 3.
As it can be seen, experimental data are affected by some noise.

A new modular design (MD) has been applied to test method for proportional relief valve characteristics, which realized the real-time data acquisition for multi-path pressure signal of automatic measurement & control and hydraulic system for steady state and dynamic state of DBE series proportional relief valve, and conducted analysis such as time domain, frequency domain, visualization and so on to collected data, obtained rather valuable test data and characteristics conclusion.
With good compatibility with virtual instrument LabVIEW software and rather high cost performance, it can effectively improve the whole performance of data acquisition system.
Carry out data acquisition and time-domain & frequency-domain analysis by means of LabVIEW and MATLAB.
Through design improvement and modular processing to the existing proportional relief valve test experiment, this system combines virtual instrument computer-aided test technology with MATLAB software, realizes real-time acquisition to two-channel and four-channel pressure signal and conducts time domain, frequency domain and visualization as well as other analysis to collected data.
Experiments show that, the proportional relief valve characteristic platform has reasonable structural design, compact size, stable performance and good cost performance; the test analysis system is efficient and convenient, the data analysis is reliable, and the test precision reaches the industrial measurement standard, all these lay good foundation for subsequent proportional valve pressure, flow-rate, displacement comprehensive test as well as multipoint real-time synchronous data acquisition.

Specifically, the transferred and processed data is used by automated driving systems installed onboard to lead the vehicle through its path, by applying all necessary commands.
As data generated by scheduling and monitoring systems and vehicles increased, managing this data efficiently was crucial for decision-making [11].
Data-driven learning methods can identify multiple patterns and enable quick and efficient decision making to choose from those patterns.
External factors might influence V2X communications, due to distance, weather or other scenarios in which data transfer is not ideal, creating a delay in receiving and processing data.
A less probable delay is still possible – the reaction of the vehicle from when the data is received, to when the required actions are implemented.

Because of the data dependences or interactions among LPs, synchronization protocols have to be introduced to PDES to guarantee the so-called local causality constraint (LCC) [26].
However, the NSM is inherently combined with the sequential semantics, and all sub-volumes share one common data structure for events or messages.
Thus, directly parallelization of the NSM may be confronted with the so-called boundary problem and high costs of synchronously accessing the common data structure [29].
In order to obtain higher efficiency of parallel simulation, parallelization of NSM has to firstly free the NSM from the sequential semantics and secondly partition the shared data structure into many “parallel” ones.
Several challenges have been overcome, such as state saving, roll back and especially GVT reduction in parallel execution of simulations.

Suspensions of composite binders are characterized by a typical thixotropic character of the flow (Fig. 5), however, the kinetics of viscosity reduction of suspensions of different composition differs significantly from each other.
After static computer processing of experimental data, mathematical models of changes in the strength and density of the solidified mortar from the amount of plasticizer and the fraction of the volume of the fine filler were obtained (Fig. 7).
The rational dosage of the plasticizer using VNV-50 based on quartz of metamorphogenic origin is 0.3 % by weight of cement in the composition KV, using VNV–50 on the basis of Intrusive-magmatic origin – 0.6 %, which confirms the previous data.
The analysis of the data obtained for the Flexural strength showed that the introduction of the optimal amount of the additive in the composition of KV on the basis of quartz and metamorphic Genesis in the early stages of hardening (3 and 7 days) provided an increase of strength by 40% and 20%, respectively, compared to the strength of the hardened mortar on the basis of quartz of igneous origin.
Thus, a reduction in viscosity in a series: TMC-50 → VNV-50 on the basis of Intrusive-magmatic quartz and melamineformaldehyde of the plasticizer → VNV-50 on the basis of metamorphic quartz and a polycarboxylate plasticizer.

Chemical equilibrium analyses of the reaction routes also indicated that reduction in temperature encourages NO2 formation while increase in temperature favours O3 production.
Nonetheless, in some urban air, several ozone related health problems such as: respiratory and throat irritation problems which cause coughing or uncomfortable sensation in the chest and in addition reduction in lung function activities as well as aggravation of asthma, have been documented [8, 9].
Computational Methods: The computational approach adopted in the study involved the use of Gaussian 03 (G03) model chemistry package with input data drawn from structural configurations produced by the GaussView simulation package.
The findings of this study are based on the data consisting of the enthalpies of formation and Gibbs free energy of formation which was generated from the use of G03 computational model chemistry package.
This was ascertained from the analyses of the chemical reaction equilibrium of the various routes which indicated that a reduction in temperature encourages NO2 formation while increase in temperature favours O3 production.

And intelligently dealing with electricity bills processing, as well as seamless power supply, which realize marine energy conservation and low-carbon emissions reduction in the port, can ensure to realize uninterruptable power on-shore connection, and at the same time promote the development of intelligent port.
Introduction It can be able to realize uninterruptable power on-shore connection board the ship, through the use of seamless power supply and intelligently dealing with electricity bills processing, so as to realize the ship energy conservation and emissions reduction in port.
Power system management can be proceeded via the alarm monitoring, data monitoring and the analysis; and also can change 10.0 kV/50 Hz, 6.0 kV/50 Hz power system in harbor grid by frequency conversion to 6.6 kV/60 Hz A.C. system, and also control the power supply of better quality; more scientific measurement of electricity can be carried out according to the market price, equipment and management cost; meanwhile,running simulation and processing information, through flexible building and configuration, it can carried out that integrity of shore power equipment management, monitoring, control, protection, billing and simulation and information processing, each of which is independent on the function, so as to satisfy the requirement of high voltage level shore power access.
Computer control closed KM3 after in parallel transferring load, at this time the ship power grid has entered into a state of shore power supply, computer proceeds to real-time detect power of load board the ship and the quantity of electricity through statistic, and  to store data about quantity of electricity consumption.
When shore power was connected into marine electric power system, GTO conducting, there is circulation current between shore power transformer and marine generators before the synchronization, as long as circulation current reaches a certain value, the gate control gain the control signal, GTO disconnect, and L reactor access current limit and automatic synchronization, as well as, marine generators have finished synchronization, marine generators exit, shore power transformer begins to supply power; in the case of normal circulation current, the gate can get computer time signals and the circulation current detection data signals at the same time , GTO conducting, L reactor shorted, and shore power transformer suppling power directly.
