This paper proposes the two-stage control structure which is composed of battery management unit and central management unit in order to improve the monitoring and management technology of integrated power supply in power system. The paper presents a battery management system (BMS) design scheme. We designed its hardware circuit and verified in the laboratory conditions. The results show that the...
Assisted living and home monitoring systems are gradually becoming a necessity, considering the current trends in population ageing and older adults' desire to continue living independently in their homes and their communities for as long as possible. This paper presents our current achievements regarding the implementation of a cyber-physical system for assisted living and home monitoring, developed...
State Islamic University of Syarif Hidayatullah Jakarta as rapid growing university towards world-class university placed in The edge of Jakarta has a data center runs by its unit of organization called Pustipanda (The Center of Information Technology and Database). The team had made observations during the last one year and found that these data center lately had an incident occurred where its hardware...
With an increase in the number of warehouses, cold storage units and factories in today's industrialized and automated world, the need for monitoring various attributes in such factories has become a thing of great necessity. With advances in technology, and in particular, the various sensors to measure different parameters such as temperature, gases, humidity etc. have become more viable and affordable...
Physical unclonable functions (PUFs) take advantage of the effect of process variation on hardware to obtain their unclonability. Traditional PUF design only focuses on the analog signals of circuits. An arbiter PUF, for example, generates responses by racing delay signals. Implementations of such PUFs usually employ large area and power consumption while providing very low throughput. To address...
The introduction of Internet of Things (IoT) and smart cities is widely viewed as a great opportunity that stimulated the modern view of wireless sensor networks (WSNs). Up to this point, WSNs were application-driven systems with well defined challenges and requirements. The idea of IoT and smart cities increased the amount of available data and magnified the hardware and software challenges of sensor...
Heating, ventilation, and air conditioning (HVAC) systems can consume a large percentage of the energy used in a typical building. Intelligent building automation systems (BAS) are widely deployed to enable more efficient HVAC utilization, thus reducing the energy consumed. Enhanced data requires distributed sensing. We propose an instrumentation system for a low-cost, over-the-top efficiency monitor...
Continuously increasing application demands on both High Performance Computing (HPC) and Embedded Systems (ES) are driving the IC manufacturing industry on an everlasting scaling of devices in silicon. Nevertheless, integration and miniaturization of transistors comes with an important and non-negligible trade-off: time-zero and time-dependent performance variability. Increasing guard-bands to battle...
CPS, that consist of a cyber part – a computing system – and a physical part – the system in the physical environment – as well as the respective interfaces between those parts, are omnipresent in our daily lives. The application in the physical environment drives the overall requirements that must be respected when designing the computing system. Here, reliability is a core aspect where some of the...
Arowana is a kind of fish which requires routine and patience maintenance techniques, particularly in terms of feeding and conditioning the water in aquarium which is quite specific. Lack of proper maintenance may affect the physical growth of arowana. It has been built a system to monitor and maintain the arowana, called Automatic Arowana Raiser (AURORA). So that the fishes can be monitored and the...
In recent days, our way of living has been changed more, lead to health consciousness, so health monitoring system is most important part of our life. In this proposed method, an RTOS based Wireless Sensor Network architecture has been developed for the health monitoring. One node acts as central and the others will be a slaves which are used for data acquisition. Data acquisition node uses the Peripheral...
There is an ever growing need for a fluxless chipjoin process to alleviate the difficulties associated with fluxcleaning in small gaps and to target fluxless packagingapplications such as required for advanced photonics. Moreover, a fluxless process can enable new process flows such as in-line underfill of fragile structures or acombination tack and mass reflow operations for 3D packages. This paper...
To solve problems that existed in wired water monitoring system, such as high cost and restricted monitoring water range, a kind of Lijiang River water environment monitoring system is designed based on WSN. In order to ensure long survival time of the sensor node and a high performance of routing node, MSP430 and ARM32F107 processor are employed respectively. After preprocessing data, MU709 3G module...
Resilience is an important challenge for extreme-scale supercomputers. Failures in current supercomputers are assumed to be uniformly distributed in time. However, recent studies show that failures in high-performance computing systems are partially correlated in time, generating periods of higher failure density. The detection of those periods is important in order to adjust the system to new conditions...
Health monitoring involves sensing, reporting, and sometimes adjusting the states of objects or nodes remotely. This paper describes the design and implementation of a real-time distributed hardware health monitoring framework, assuming a homogeneous set of hardware nodes. The framework consists of sensor components operating at the nodes, and visualization components operating at monitoring stations...
The global use of agrochemicals and pesticides has increased due to the development of agricultural technologies. Evidence of the toxicity of these chemicals has been detected in beehives. In order to find the relationship between the ecosystem's contamination and the behavior of bees, we developed a device that samples audio and temperature in hives. This correlation would allow the use of apiaries...
High Performance Computer (HPC) systems typically have lifetimes of four to six years. During this lifetime a system will undergo substantial changes in the system software stack and hardware configuration. Simultaneously, the physical environment around it will change as old systems are retired and new systems are brought in. This report focuses on our experience with Mustang, a 1600 node Linux cluster...
Software-intensive systems often consist of many components that interact to fulfill complex functionality. Testing these systems is vital, preferably by a minimal set of tests that covers all relevant cases. The behavior is typically specified by scenarios that describe what the system may, must, or must not do. When designing tests, as in the design of the system itself, the challenge is to consider...
There are different kinds of datacenter monitor system, but most of them just monitor a few aspects of runtime data. Some of them just focused on temperature monitoring and power consumption. And others are focusing on application behaviors and system resources. So they can't reflect the running state of a datacenter precisely. In this paper, we introduce a platform which aims at monitoring multilayer...
Embedded system face a serious threat from physical attacks when applied in critical applications. Therefore, modern systems have several integrated sensors to detect potential threats. In this paper, we put forward a new issue where these sensors can open other security loopholes. We demonstrate that sensors, which are deployed to prevent faults, can be exploited to insert effective and almost zero-overhead...
