The Western Australian Rangeland Monitoring System (WARMS), a state government monitoring activity, provides information on change in Western Australia’s pastoral rangelands. It consists of a set of permanent sites, on which measurements of perennial vegetation (direct census in shrublands and perennial grass frequency and woody cover in grasslands) and assessments of soil surface condition are recorded at either 3-year (grasslands) or 5-year (shrublands) intervals. Data collection is non-destructive. Site distribution is based on vegetation type, and WARMS reports at the vegetation type or regional level, not individual site or property level. Operating WARMS requires a range of defined conventions to ensure that personnel changes and the interval between samplings at any one site do not lead to confounding of results through variation in how data are collected. The number of sites (1622) and program timeframe (decadal) mean that data storage and management issues are critical. Data interpretation, including the interpretive framework and use of ancillary data to assist in interpreting causality, and provision of information products relevant to a range of users are also important operational aspects. A companion paper addresses the institutional requirements for WARMS, system design and the rationale behind this design.

Abstract: With the expanding utilization of instant chat messengers to share data, Suspicious exercises have additionally expanded. There are numerous sources to share the data however moment talk couriers and informal communication sites are fast, simply intended to share anything. In some cases, even new stories are at first separated via online media locales and further on talk couriers rather than any news channel and paper and so forth. Because of these innovation progressions, a few individuals are using these applications inappropriately to share suspicious messages and make arrangements to accomplish something unlawful. With the headway of web innovation and the change in the method of correspondence, it is discovered that much direct news has been examined in Internet discussions well before they are accounted for in conventional broad communications. Additionally, this correspondence channel gives a viable channel to criminal operations, for example, communicating of copyrighted films, compromising messages and internet betting and so on. Our Proposed Framework will examine online plain text messages from chosen conversation gatherings and our framework will choose which post is legitimate and unlawful. It will detect the suspicious keyword from the chatting and give a warning message to the user and also a mail will be sent to admin which will include all the details of the user. Keywords: Suspicious Chat, Chat Monitoring, Abusive word, Terrorist activities, Chat Tracking.

Tire blowout is a very serious security incident, particularly on the highway. As the existing anti-blowout device and measures also failed to meet the requirements to ensure traffic safety, research and development of prevention and treatment system is particularly important. In light of this, the Tire Pressure Monitoring Inflatable Restraint System is put forward. Sensor can send signals to the controller, and then the controller directs the gas generator to generate a lot of gas instantly, and through a special airway tire is inflated, so that the instability of the vehicle is eased. The concept of "vacuum tube tire" is first proposed, it can adapt to the inflation process better. Tire blowout, drunk driving and speeding is called together "three big killers on road" in China, so we can see that there are many incidents like these. Meanwhile, tire blowout is not like the other two which can be prevented by human’s means, it is sometimes not within our control. According to statistics, 70% of national highway traffic accidents are due to tire blowout, and a speed of more than 160km/h makes mortality possibility up to nearly 100%. In the check of the tires, more than 40% of them have security risks. [1] Statistics show that: The main reason why traffic accidents of high-speed driving keep increasing is leaked or inflated tires. In China, there is statistical data show that 46% traffic accidents on the highway were due to tire problem, in which tire blowout accounts for more than 70% of the total accidents, and the most crucial reasons of this is because the owners’ improper tire maintenance method. Beyond the boring concept, we can see a bunch of rather alarming figures, accounting for 49.81% highway accidents deaths, 63.94% injuries, 43.38% direct property loss were caused by high-speed tire blowout. High-speed tire blowout is considered to be the super-killer of traffic safety. And all the tire blowout incidents warn people to pay attention to tire safety.

The practice of monitoring active volcanoes, includes several techniques using either direct or remote measurements, the latter being more important for volcanoes with limited accessibility. We present the Volcanic Anomalies Monitoring System (VOLCANOMS), a new, online, low-cost and semiautomatic system based on Landsat imagery. This system can detect permanent and/or temporal thermal anomalies in near-infrared (NIR), short-wave infrared (SWIR), and thermal infrared (TIR) bands. VOLCANOMS allows researchers to calculate several thermal parameters, such as thermal radiance, effective temperature, anomaly area, radiative, gas, convective, and total heat, and mass fluxes. We study the eruptive activity of five volcanoes including Krakatau, Stromboli, Fuego, Villarrica and Lascar volcanoes, comparing field and eruptive data with thermal radiance. In the case of Villarrica and Lascar volcanoes, we also compare the thermal radiance and eruptive activity with seismic data. The thermal radiance shows a concordance with the eruptive activity in all cases, whereas a correlation is observed between thermal and seismic data both, in Villarrica and Lascar volcanoes, especially in the case of long-period seismicity. VOLCANOMS is a new and powerful tool that, combined with other techniques, generates robust information for volcanic monitoring.

Background: To be able to compare continuous glucose monitoring (CGM) systems, they have to be worn in parallel by the same subjects. This study evaluated the performance and usability of three different CGM systems in direct comparison. Method: In this open, prospective study at two sites, 54 patients with diabetes wore three CGM systems each (Dexcom G5™ Mobile CGM system [DG5], Guardian™ Connect system [GC], and a Roche CGM system [RCGM]) in parallel for 6 or 7 days in a mixed inpatient and outpatient setting. Capillary comparison measurements were performed using a self-monitoring of blood glucose (SMBG) system. During study site visits, glucose excursions were induced. Performance of the systems was evaluated by calculating mean absolute relative differences (MARD, calculated as absolute differences for glucose concentrations <100 mg/dL and as relative differences for glucose concentrations ≥100 mg/dL), and mean relative differences (MRD, bias) between CGM and SMBG results. In addition, usability of the systems was assessed. Results: Overall MARD was 10.1 ± 2.1 for DG5, 11.5 ± 4.2 for GC, and 11.9 ± 5.6 for RCGM. Performance improved in all systems after the first day of use. All systems showed >99% of values within zones A and B of the consensus error grid. Overall, all CGM systems showed a small negative bias compared to SMBG. Usability of the systems differed regarding patch adhesion rate, failure rate, and patient rating. Most patients preferred GC, but in general all systems were rated positively. Conclusion: All three CGM systems showed similar overall accuracy in this direct comparison, but small differences were observed with regard to specific glucose ranges and usability aspects.

Annotation:

Due to the capacity of processing signal with low energy consumption, compressive sensing (CS) has been widely used in wearable health monitoring system for arrhythmia classification of electrocardiogram (ECG) signals. However, most existing works focus on compressive sensing reconstruction, in other words, the ECG signals must be reconstructed before use. Hence, these methods have high computational complexity. In this paper, the authors propose a cardiac arrhythmia classification scheme that performs classification task directly in the compressed domain, skipping the reconstruction stage. The proposed scheme first employs the Pan–Tompkins algorithm to preprocess the ECG signals, including denoising and QRS detection, and then compresses the ECG signals by CS to obtain the compressive measurements. The features are extracted directly from these measurements based on principal component analysis (PCA), and are used to classify the ECG signals into different types by the proposed semi-supervised learning algorithm based on support vector machine (SVM). Extensive simulations have been performed to validate the effectiveness of the proposed scheme. Experimental results have shown that the proposed scheme achieves an average accuracy of [Formula: see text] at a sensing rate of 0.7, compared to an accuracy of [Formula: see text] for noncompressive ECG data.

Cardiovascular diseases (CVDs) have been listed among the most deadly diseases worldwide. Many CVDs are likely to manifest their symptoms some time prior to the onset of any adverse or catastrophic events, and early detection of cardiac abnormalities is incredibly important. However, traditional electrocardiography (ECG) monitoring systems face challenges with respect to their scalability and affordability as they require direct body contact and cumbersome equipment. As a step forward from the large-scale direct-contact ECG monitoring devices, which are inconvenient for the user in terms of wearability and portability, in this research, we present a small-sized, non-contact, real-time recording system for mobile long-term monitoring of ECG signals. The device mainly comprises three non-contact electrodes to sense the bio-potential signal, an AD8233 AFE IC to extract the ECG signal, and a CC2650 MCU to read, filter, and transmit them. The device is powered by a 2000 mAh lithium-ion battery with isolation between digital and analog powers on the board using two low-dropout regulators (LDOs). The board’s dimension is 8.56 cm × 5.4 cm, the size of a credit card, making it optimal to be worn in a shirt chest pocket. In spite of its small form factor, the device still manages to achieve a continuous measurement battery life of over 16 h, total harmonic distortion below −30 dB across the interested frequency range, an input-referred noise as low as 1.46 µV for contacted cases and 5.15 µV for non-contact cases through cotton, and clear ECG recording for both contact and non-contact sensing, all at a cost around USD 50.

The monitoring of biofouling is continuously evolving with new and better techniques being developed all the time. The major drawback of the currently used techniques is that these methods are complicated and time-consuming, involving culturing and counting of attached organisms. A continuously circulating batch culture system was therefore designed to study biofouling spectrophotometrically. Absorbance of bacteria attached to a glass tube was compared with direct counts done on DAPI-stained bacteria attached to 3CR12 coupons. Direct measurements of absorbance correlated well with the total counts obtained using the DAPI technique (r2=0.925). Spectrophotometry proved to be an easy, inexpensive and reliable alternative to techniques requiring laborious counting of microorganisms, for example the DAPI technique, for quantification of biofouling.

Recent technical development focused on real-time heart rate monitoring instead of postexercise evaluation of recorded data. There are several systems on the market that allow direct and real-time monitoring of several individuals at the same time. The present study compared the systems of Polar, Acentas, Activio, and Suunto in a field test with twelve subjects regarding failure quota, operating distance, and ECG validity. Moreover, the installation and use of software and hardware were evaluated with a quality rating system. Chest belts were evaluated with a questionnaire, too. Overall the system of Acentas reached the best mark of all systems, but detailed results showed that every system has its advantages and disadvantages depending on using purpose, location, and weather. So this evaluation cannot recommend a single system but rather shows strength and weakness of all systems and additionally can be used for further system improvements.

Large forest fires are very hazardous and often cause greater losses. However, due to the vast coverage of forests and the environmental complexity, monitoring which relies on sensor detection of direct contact almost cannot achieve its monitoring function. In this paper, the author proposes that long-range images will first be acquired and so do the images of a larger dynamic range of the observed region, then an embedded video monitoring system will be formed realizing a dynamic monitoring. With the techniques of dynamic image analysis and processing, dynamic image alarms and control signals can be obtained and such videos will be transmitted over the Internet in real-time. Experiments shows this system respond to fires with a fast speed of less than 20ms and the control of fire is highly accurate with a dynamic image area that is less than 1% of the background area.

Annotation:

The Western Australian Rangeland Monitoring System (WARMS) consists of a set of ~1620 permanent sites distributed across the pastoral rangelands of Western Australia used for commercial livestock grazing. The system is designed to provide information to government and the general community on changes in Western Australia’s rangelands, rather than to individual landholders. It is designed to report at the regional or vegetation type level by selectively sampling representative areas of the rangelands, with representation occurring at several levels. The system was fully implemented by 1999 and all sites, except a small number of ongoing replacements, have now been re-assessed at least once. Two site types are used. In grassland areas, the frequency of all perennial species is assessed, and an estimate made of crown cover of woody perennials. In shrubland areas, a direct census technique is used, with the demography and maximum canopy dimensions of all shrubs recorded. Changes in soil surface condition and patch distribution are also assessed using standard Landscape Function Analysis (LFA) techniques. The vegetation and soil surface information is used to indicate rangeland change. The system is not fixed within any single model of range dynamics and the outputs of WARMS can be interpreted in various ways, depending on the specific requirements of the end-user. The paper includes discussion of the institutional requirements for WARMS, the site stratification and selection criteria, description of the field methods used and the rationale behind its design. It also considers the implications of the site stratification and selection criteria in terms of the caveats that need to accompany reporting.

Aiming at the practical problems existing in the fire disaster monitoring, such as harsh site conditions, the detection point difficult to change and expand, low automation level and the monitoring products having higher prices, etc., a fire disaster environment parameters intelligent monitoring system is designed based on the ZigBee CC2530 wireless communication chip. By deploying sensor network nodes in monitoring area, the monitoring information, that is, temperature, humidity, and smoke concentration of the fire site, is aggregated to the central monitoring system in order to achieve a unified data management and network routing monitoring functions. The central monitoring computer stores and displays the data sent by ZigBee network, thus the real-time monitoring of changes in environmental parameters of the fire site is achieved. The monitoring results have shown that this system is stable, high reliable in data transmission and easy to use, and can be used in environmental monitoring occasions inconvenient of direct attachment.

Since the National Highway Traffic Safety Administration mandated the incorporation of tire pressure monitoring systems (TPMSs) in all newly produced passenger vehicles, most vehicle manufacturers have adopted direct pressure measurement. Direct TPMS sensors embedded in each tire require a wireless radio frequency (RF) communications link that broadcasts tire status to the vehicle once per minute from each tire when at speed. Each TPMS message communicates benign information that includes pressure and temperature as well as a static unique identifier that may be exploited, which raises concerns about privacy and spoofing. To focus on concerns related to the TPMS-RF interface, vehicle motion simulations were integrated with live propagation modeling measurements from three classes of passenger vehicles: subcompact car, full-size sedan, and full-size pickup. The RF link and channel models for this TPMS interface with the vehicle resulted in surprisingly long ranges away from the vehicle for the radiation of the unique identifiers. A TPMS sensor redesign could use the proposed RF channel propagation measurements to change the directions of signal propagation while reducing battery consumption by the TPMS sensor (which is affected primarily by RF transmission).

Some remote sensing applications are relatively time insensitive, for others, near-real-time processing (results 30-180 minutes after data reception) offer a viable solution. There are, however, a few applications, such as active wildfire monitoring or ship and airplane detection, where real-time processing and image interpretation offers a distinct advantage. The objective of real-time processing is to provide notifications before the complete satellite pass has been received. This paper presents an automated system for real-time, stream–based processing of data acquired from direct broadcast push-broom sensors for applications that require a high degree of timeliness. Based on this system, a processing chain for active fire monitoring using Landsat 8 live data streams was implemented and evaluated. The real-time processing system, called the FarEarth Observer, is connected to a ground station’s demodulator and uses its live data stream as input. Processing is done on variable size image segments assembled from detector lines of the push broom sensor as they are streamed from the satellite, enabling detection of active fires and sending of notifications within seconds of the satellite passing over the affected area, long before the actual acquisition completes. This approach requires performance optimized techniques for radiometric and geometric correction of the sensor data. Throughput of the processing system is kept well above the 400Mbit/s downlink speed of Landsat 8. A latency of below 10 seconds from sensor line acquisition to anomaly detection and notification is achieved. Analyses of geometric and radiometric accuracy and comparisons in latency to traditional near-real-time systems are also presented.

Automated heating, lighting and irrigation systems are nowadays standard features of industrial and commercial buildings, and are also increasingly found in ordinary housing. In addition to the benefits of user comfort, automated technology for buildings saves energy and, above all, it provides enhanced protection against leakage of water and hazardous gases, and against fire hazards. Lightning strikes are a natural phenomenon that poses a significant threat to the safety of buildings. The statistics of the Fire and Rescue Service of the Czech Republic show that buildings are in many cases inadequately protected against lightning strikes, or that systems have been damaged by previous strikes. A subsequent strike can occur within the period between regular inspections, which are normally made at intervals of 2–4 years. Over the whole of Europe, thousands of buildings are subjected to the effects of direct lightning strikes each year. This paper presents ways to carry out wireless monitoring of lightning strikes on buildings and to deal with their impact on lightning conductors. By intervening promptly (disconnecting the power supply, disconnecting the gas supply, sending an engineer to inspect the structure, submitting a report to ARC, etc.) we can prevent many downstream effects of direct lightning strikes on buildings (fires, electric shocks, etc.) This paper introduces a way to enhance contemporary home automation systems for monitoring lightning strikes based on wireless sensor networks technology.

Cutting temperature measurement and its variety tendency can reflect cutting tool performance and machined surface quality directly. By means of a mercury current collector or an electrical brush device the online measurement of thermoelectric potential of tool-workpiece natural thermocouple in milling is obtained, based on which a new cutting process real-time monitoring system is developed. The system takes the average cutting temperature in tool-workpiece interface as the monitoring target and the rotation rate of machine spindle as the adjustment object, which leaves out onerous and complex modeling and makes the monitoring and adjustment objective, direct and effective.

This research was made with the aim to help companies in controlling receivables. The study was conducted on companies engaged in the sale and purchase of motorcycles. These companies act as suppliers of goods and collaborate with credit financing institutions or what is commonly called leasing. Every credit sale will form a lease receivable that must be paid by the related leasing party. In general, many receivables have not been paid from the due date of the agreement. This impedes the company's financial productivity. From these problems, researchers create a system that can be used to meet the needs of the company, in relation to receivables. Researchers create a system that can improve performance to be more effective and dynamic, especially to record the daily control of receivables, namely by using the Leasing Accounts Recording and Monitoring System. The design of recording and monitoring systems for receivables is made using the direct recording method. Systems development methods using the R & D. Method stages in the R & D method include potential problems, information gathering, product design, design validation, design improvement, product testing, product revision, trial use, mass product manufacturing. The design of a monitoring system for leasing receivables billing, can help companies control receivables. Leasing Receivables Recording and Monitoring System can minimize receivables losses.

Logistics and transport have become an increasingly important topic in recent years. In this kind of scenario, being able to offer added value to users means an important improvement in the services offered by the different companies. Different actors take part in the process of sending, transportation and collection of the different products through roads, ports and airports. During this process different aspects of security must be taken into account, since an error in one of them can cause major problems for public health, nature or even the economy of a country. With all this in mind, this work proposes a new system that allows us, through the use of wireless technologies such as Radio Frequency Identification, Global Positioning System, Wi-Fi Direct and mobile communication technologies, to automate the process of authentication and tracking of different products and goods. The proposed scheme allows through the use of the cloud the creation of a ubiquitous communications system for monitoring, control and even automation of repositioning orders automatically. In addition, the use of a system based on blockchain allows to carry out the whole process in an optimal way that guarantees the privacy and immutability of the data referring to the transports and merchandise. This work allows to reduce costs and improve the quality of the processes of sending, transport and reception of products for the different companies involved in the supply chain.

A study was carried out to gather necessary information through data mapping, in-depth interviews with key stakeholders, document reviews, application development, direct entry in the field using mobile development, application testing and analysis that was conducted on for 253 respondents. To obtain a full picture on early childhood education, data on child growth and education shall be mapped and linked in one application. We introduce a mobile app to systematically compile the individual as well as group data across different aspects of child life, ranging from child education. Using a tablet PC or mobile phone, data could be easily entered at any time by the person. Due to still poor infrastructure at the grass root level, the system also allows a safety store offline that could automatically link to server when network connection is available. The immediate data entry will provide real-time data report that could be accessed by any relevant stakeholders at any levels to response accordingly. However, to avoid misuse of data, the access will also be restricted with a secured login system. Based on the study, this application is easily applicable for real-time monitoring and evaluation on early child education.

In several epidemic diseases, one of the main symptoms exhibited by people is abnormal body temperature. Therefore, monitoring body temperature is crucial for preventing the spread of infectious diseases and facilitating timely responses. This study presents a wearable bracelet that can be used as a temperature monitoring and trajectory analysis system. The temperature sensor in the bracelet can effectively monitor the body temperature of the wearer in the target scene, and the data transmission between the bracelet and the data collector can effectively detect the movement range and trajectory of the wearer. Through these, the whole set can also detect the direct and indirect contact of the wearer in any period of time, which is very helpful for the prevention and control of infectious diseases and the isolation of potentially infected persons.

Design safety analysis provides a sound basis for determining the functional requirements of a rotorcraft health and usage monitoring (HUM) system for flight safety purposes, since it considers the vulnerability to catastrophic failure of every component in each safety-critical system. The process thereby identifies the components that may be dependent upon effective monitoring systems in order to achieve the system safety objectives. From the analysis of a new transmission system design, examples are given of component potential failure modes that either (a) are expected to be preventable by direct design action, or (b) will require the additional support of indirect action such as HUM provisions. Many of these examples are expected to be applicable to new rotorcraft transmission designs in general. A brief review of analysis procedures appropriate to rotorcraft transmission systems is included.

The reliable operation, dynamic performance analysis and control strategy research of a switched reluctance motor (SRM) require an online monitoring system to display and record its operating status. However, due to the large amount of data, the nonlinear electromagnetic characteristics and the harsh working environment of SRM, it is very difficult to monitor a SRM’s operation status in real time. In order to solve these problems, a new structure of the SRM monitoring system, which uses Digital Signal Processor (DSP) and the hardwired Transmission Control Protocol/Internet Protocol embedded Ethernet controller W5500, is presented in this paper. The W5500 and DSP’s direct memory access modules are employed for data capture and transfer to reduce the digital signal processing workload. The digital signal processing program is implemented by the hybrid programming method, which shortens the filtering time. Consequently, the DSP has sufficient resources to acquire multiple signals with a high sampling frequency and can adopt a more complex filtering algorithm, which enhances the accuracy and real-time performance of the system. Moreover, the amplitude–frequency characteristics of signals are analyzed. Then, the detection circuits and finite impulse response filters are designed to achieve the targeted acquisition and filtering. Besides, the impact of harsh environment on the system is reduced by adjusting the data transmission modes according to different working conditions. As a result, the scope of application of the system has been extended. The proposed system has a novel structure and strong practicability, which exhibits great guiding significance for the development of a SRM.

Monitoring of structures during operation is a direct requirement of the current legislation, especially relevant for technically complex structures, which include high-rise buildings. It is important not only for ensuring mechanical safety during construction operation, but also as a tool for reverse analysis of the actual stress-strain state of structures and foundations for compliance with the design calculation forecast, which should ultimately contribute to the development of construction theory and practice. The article is devoted to the organization of monitoring during the operation of the Lakhta Center skyscraper in St. Petersburg. The basis of the monitoring system is a design model of the building that interacts with the base making it possible to give the monitoring an interactive character. Particular attention is paid to the definition of «alarms» that make it possible to signal timely about the occurrence of negative trends helping to eliminate the occurrence of an emergency. It is shown that the calculations for justifying the criteria of monitoring systems differ significantly from the usual calculations when designing. The article defines the features of a workable monitoring system, to which the system implemented in practice fully corresponds. A comparison of the readings set in the design of measuring equipment and design expectations is given. The example of a high-rise building shows how to assign the «alarm» and «accident» criteria to ensure the operability of the monitoring system during operation.

The battery monitoring system (BMS) plays a crucial role in maintaining the safe operation of the lithium battery electric bicycle and prolonging the life of the battery pack. This paper designed a set of new battery monitoring systems based on the Android system and ARM single-chip microcomputer to enable direct management of the lithium battery pack and convenient monitoring of the state of the battery pack. The BMS realizes the goal of monitoring the voltage, current, and ambient temperature of lithium batteries, estimating the state of charge (SOC) and state of health (SOH), protecting the battery from abuse during charging or discharging, and ensuring the consistency of the batteries by integrating the passive equalization circuit. The BMS was proven effective and feasible through several tests, including charging/discharging, estimation accuracy, and communication tests. The results indicated that the BMS could be used in the design and application of the electric bicycle.

Based on system execution traces, this paper presents a dynamic approach for visualizing and debugging timing constraint violations occurring in distributed real-time systems. The system execution traces used for visualization and debugging are collected during the execution of a target program in such a way that its run-time behavior is not interfered with. This is made possible by our non-interference distributed real-time monitoring system which is capable of collecting system’s run-time traces by monitoring and fetching the data passing through the internal buses of a target system. After the run-time data has been collected, the visualization and debugging activities then proceeded. The timing behavior of a target program is visualized as two graphs—the Colored Process Interaction Graph (CPIG) and the Dedicated Colored Process Interaction Graph (DCPIG). The CPIG depicts the timing behavior of a target program by graphically representing interprocess relationships during their communication and synchronization. The DCPIG can reduce visualization and debugging complexity by focusing on the portion of a target program which has direct or indirect correspondence with an imposed timing constraint. With the help of the CPIG and the DCPIG, a timing analysis method is used for computing the system-related timing statistics and analyzing the causes of timing constraint violations. A visualization and debugging system, called VDS, has been implemented using OpenWindows on Sun-4’s/UNIX workstations.

Intraoperative neurophysiological monitoring during brain surgery uses direct cortical stimulation to map the motor cortex by recording muscle activity induced by the excitation of alpha motor neurons (MNs). Computational models have been used to understand local brain stimulation. However, a computational model revealing the stimulation process from the cortex to MNs has not yet been proposed. Thus, the aim of the current study was to develop a corticomotoneuronal (CMN) model to investigate intraoperative stimulation during surgery. The CMN combined the following three processes into one system for the first time: (1) induction of an electric field in the brain based on a volume conductor model; (2) activation of pyramidal neuron (PNs) with a compartment model; and (3) formation of presynaptic connections of the PNs to MNs using a conductance-based synaptic model coupled with a spiking model. The implemented volume conductor model coupled with the axon model agreed with experimental strength-duration curves. Additionally, temporal/spatial and facilitation effects of CMN synapses were implemented and verified. Finally, the integrated CMN model was verified with experimental data. The results demonstrated that our model was necessary to describe the interaction between frequency and pulses to assess the difference between low-frequency and multi-pulse high-frequency stimulation in cortical stimulation. The proposed model can be used to investigate the effect of stimulation parameters on the cortex to optimize intraoperative monitoring.
