Electricity is one of the basic needs in the era of technological development, where all equipment must use electricity to operate such as computer, so that it requires a system that can monitor power consumption at computer cluster. To monitoring power consumption using WCS1800 to current sensor and microcontroller Atmega32 to data sensor process, and serial communication to send data to display at personal computer. From test system having two result, first is power consumption at computer cluster starting, where current value range is 0 to 38A with power consumption is 0 to 8360 watt. And second is power consumtion at computer cluster execution progran, current value is 27 to 40 A, with power consumption 5940 to 8800 watt. From this system has been design, the power consumption at computer cluster can be monitored and known value of energy consumption.

In this paper, we propose a novel Bridge Weight-In-Motion (B-WIM) detection method based on the bridge deck vibration signal analysis with the image mapping algorithm. The algorithm maps the vibration signals into 8-Bit grayscale images and then uses image sharpness to detect B-WIM in single-vehicle tests. The result shows that the proposed method can effectively estimate B-WIM. © 2017 IEEE.

Informal caregivers of people with Alzheimer's disease and related dementias (ADRD) are at risk of poor mental health. This study aimed to investigate the feasibility and validity of studying caregivers' mental stressors using online caregiving forum data (March 2018-February 2022) and natural language processing and machine learning (NLP/ML). NLP/ML topic modeling generated eight prominent topics, which we compared with qualitatively defined themes and the existing caregiving framework to assess validity. Among a total of 60,182 posts, 5848 were mental distress-related; for the ADRD patients (symptoms, medication, relocation, care duty share, diagnosis, conversation strategy) and the caregivers (caregiving burden and support). While we observed novel topics from NLP/ML-defined topics, mostly those were aligned with the existing framework. For feasibility assessment, qualitative title screening was done. The findings shed new light on the potential of NLP/ML text analysis of the online forum for informal caregivers to prepare tailored support for this vulnerable population.

In complex (dynamic) systems, models are usually too complex for a direct evaluation, and simulation is the method of choice (indirect optimization). Another aspect is the structure of the design space for complex system. In a recent paper of the authors, an approach is presented for design space description with a UML profile-based description of architectural variations of complex dynamic systems. In order to execute a simulation of a system variant, one has to be chosen based on the used heuristic, and specified in a standardized way to be used for constructing the actual simulation model with the use of a library of template models. This paper approaches a method to automatically generated individual UML object models from the design space specification for a given parameter selection. ©2017 Society for Modeling & Simulation International (SCS).

The server room is a room that stores data, there is company information (Data Center). Hot server room conditions can cause performance on the device and network to decrease. Therefore an admin must keep the server space stable so that the server and network performance is maintained. The temperature monitoring system can be used to monitor temperature and humidity in the server room. In addition, it provides a response to reduce the temperature if there is a temperature increase in the server room. This study uses the Internet of Thing (IoT), which is a device used by the Raspberry Pi and Wemos DHT Shield wireless sensor as a device that is able to read the temperature and humidity conditions of the room. Temperature and humidity log data is stored in the MySQL database, then displayed in a chart diagram in real time. IoT response based on predetermined temperature standards by giving notifications to users via Whatsapp Application on mobile devices.

One of the biggest challenges during the overall promotion of computer industry is the security risk issue. Most of the existing approaches for quantifying security risks are based on simple multiplications of frequencies and quantitative consequences of hazard occurrence without considering dependencies among the hazards. In this paper, we model sequential attacks, which involve multiple sequence-dependent hazardous actions for a successful attack. We also explore a Markov-based method to estimate the occurrence probability of security risks for systems subject to the sequential attacks. The method is demonstrated through a detailed case study where Trojan attacks in the banking application are modeled and analyzed.

Core Ideas: We comprehensively validated the use of UAS in sorghum and maize breeding programs. Temporal estimates of plant growth will allow researchers to elucidate new phenotypes. The stage of the breeding pipeline dictates the applicability of UAS platforms. The implementation of UAS is demonstrated in different crop species. Monetary and time costs should be considered before implementation of UAS. To meet future world food and fiber demands, plant breeders must increase the rate of genetic improvement of important agricultural crops. One of the biggest obstacles now facing crop scientists is a phenotyping bottleneck. To ease this burden, the emerging technology of unmanned aerial systems (UAS) presents an exciting opportunity. To assess the utility of UAS, it is important to investigate their application across multiple crop species. Terminal plant height is of great importance to maize (Zea mays L.) and sorghum [Sorghum bicolor (L.) Moench] breeders and has been hypothesized to be useful but has been logistically impractical to measure in the field. In this study, we statistically analyzed in depth the ability of UAS to estimate height in sorghum (advanced and early generation material) and maize (optimal and late material) and the application of these estimates in breeding programs. We found that UAS explain genotypic variation similarly to ground-truth methods and that the repeatability of the methodology is high (R = 0.61–0.99), indicating effective differentiation of genotypes. Additionally, correlations between ground truth and UAS measurements were moderate to high for all materials (r = 0.4–0.9). Finally, we present a novel application for the technology in the form of high-resolution temporal growth curves. Using these UAS-generated growth curves, new physiological insights can be obtained and new avenues of scientific investigation are possible.

This paper addresses the stability of a Kalman filter when measurements are intermittently available due to an unreliable communication channel between sensors and the estimator. This intermittent behaviour can be modelled as a random and time-varying measurement system. We consider a general discrete-time system with a random measurement matrix and study the stability condition for the associate Kalman filter. By deep dissecting the system structure, the necessary and sufficient stability condition for the Kalman filter is given. We also give methods to checking the stability condition for specific linear systems. Our results generalize previously known stability conditions where the system matrix structure is restricted.

Collective knowledge is understood as the common knowledge state of a collective consisting of autonomous units. The knowledge states referred from these autonomous units to some degree reflect the real knowledge state of a subject in the real world, but it is not known to what degree because of incompleteness and uncertainty. Although collective knowledge determination is an important task because these knowledge states can be different from each other, there exists another important issue with its quality. The quality of collective knowledge is based on the difference between the real knowledge state and the collective knowledge. In this study, we investigate the influence of the number of collective members on the quality of collective knowledge. Through experimental analysis, the larger collective we use, the better the quality of collective knowledge will be. In other words, the large number of collective members positively affects the quality of collective knowledge. Besides, some theorems about the relationship between the collective knowledge and the knowledge states in a collective, the influence of adding or removing members on the quality of collective knowledge are also proved. © 2017 - IOS Press and the authors.
