This paper designed a 1-Mb HfOx-based embedded Resistive Random Access Memory (RRAM) device with a one-transistor-one-resistor (1T1R) structure, and systematically investigated its working temperature range. It noted that this embedded RRAM macro has a 1.6X working temperature range than previous design for some extreme environment. Using the peripheral-assisted technique, it can enable the error...
In this paper, we aimed to build the Abnormal Behavior Profiling (ABP) of IoT devices to supplement other studies that focused on the abnormal behavior detection of IoT devices with a high accuracy rate by a wide variety of machine learning algorithms. ABP will integrate all types of abnormal behavior detection and possess a key role for the purpose of IoT security in the future. Our technical motivation...
The Jiudian Gorge water conservancy hub at the Tao River in Gansu Province is located at the entrance of the Jiudian Gorge in the middle reaches of the Yellow River tributary, Tao River. The project has a total capacity of 943 million m3 and is an all-year balancing reservoir. Under normal water level conditions, the maximum water depth in front of the dam is 103 m. The water temperature structure...
The existence of temporary misbehaving nodes is a common phenomenon in a wireless sensor network. Recent research works consider their existence and analyze their detrimental effects over the network performance. Several approaches even try to detect and overcome temporary misbehaving nodes from the network. In this paper, we propose a technique called PreCoRe to predict the occurrence of dumb nodes...

However, due to the uneven...
To guarantee the thermal safety and obtain good performance of a solid oxide fuel cell (SOFC), the operating temperature and temperature gradient of SOFC must be constrained within a proper range. Thus, it's important to obtain the spatial temperature distribution of SOFC in real time. However, the inner temperature of the fuel cell cannot be obtained by installing thermocouples with acceptable cost...
The objective of this paper is to clarify the differences between cold aisle containment (CAC) and hot aisle containment (HAC) with regard to the air-intake temperature of the ICT equipment in the rack. Thus, we constructed a system in which these two capping methods could be compared under the same load and air-conditioned environment, and measured those thermal environments. When the ICT equipment...
Insulated gate bipolar transistors (IGBTs) are one of the most critical components in the Electric Vehicles (EVs) because of their complex running environment, high power dissipation and frequent junction temperature fluctuation. Therefore, it's essential to predict the lifetime of IGBTs by considering the actual factors in applications. The aim of this paper is to present a lifetime prediction method...
A vehicle parked in the open will experience an increase in temperature in the cabin that can rise quickly in blistering conditions. As a result, the temperature in the cabin will have a temperature difference with outside temperature up to 30 degrees Celsius, thus causing uncomfortable conditions for the driver or passenger if entered the cabin. By utilizing thermoelectric modules that work with...
