In particular, each port on the same network interface card design is required to provide highly scalable and low-latency communication. In this article, we present a study of intelligent sensory application for the Ethernet-based communication architecture and performance of multi-port configuration which is mainly used in safety-enhanced application such as automotive, military, finance, and aerospace, in other words, safety-critical applications. Our contributions and observations on the highly scalable intelligent behavior: (1) proposed network interface card board design scheme and architecture with multi-port configuration are a stable network configuration; (2) timing matrix is defined for fault detection and recovery time; (3) experimental and related verificat...

Then the numbers and the location of a mobile PDA device are encoded and transmitted along with the location information to a remote server through a wireless communication network. Finally, the server decodes the transmitted data as a text format and transmits it to the destination user. Consequently, this paper contributes a case study on the embedded system for designing of intelligent interface between a moving vehicle and a mobile PDA device, using a spatial relative distance scheme. The experimental results show that detection and tracking of a location of moving vehicle can be conducted efficiently with a mobile PDA device in real-time through wireless communication system and Internet.

In this paper, we present this power dissipation problem from the clock generation and distribution side. We examine clock power efficiency and several applications as well as wireless communication circuits.

This paper suggests a tool to tune the correlation window size in a given image domain by using photo-realistic simulation methodology. To facilitate the analysis proposed in this paper, we use photo-realistic simulation methodology to generate a pair of photo-realistic synthetic images of the terrain from a pre-acquired DEM(Digital Elevation Map) and ortho-image, which can be served as the pseudo ground truth. We performed D reconstruction on synthetic images of a natural terrain and carried out the evaluation of the correlation window on DEM accuracy. Experimental results are consistent with our strong expectation about two competing factors and show that our approach can be a useful tool to tune the window size.

To show a mobile connectivity and wireless connection in wireless mesh-network, we utilized urban mobility simulation time with prediction method, and also investigated a large number of mobility flows. We also highlight how to achieve high efficiency by using the neural prediction methods and modeling directly to the mobile wireless network architecture by a software tool and library. Major results of our experimental study demonstrate good scalability and usability of our prediction of mobility model by using a statistical comparison results, and trend of mobility usages.

In particular, it is very important to be able to recognize the current surgical phase because the phase information can be utilized in various ways both during and after surgery. This paper proposes an efficient phase recognition network, called MomentNet, for cholecystectomy endoscopic videos. Unlike LSTM-based network, MomentNet is based on a multi-stage temporal convolutional network. Besides, to improve the phase prediction accuracy, the proposed method adopts a new loss function to supplement the general cross entropy loss function. The new loss function significantly improves the performance of the phase recognition network by constraining un-desirable phase transition and preventing over-segmentation. In addition, MomnetNet effectively applies positional encoding techniques, which are commonly applied in transformer architectures, t...

Available light energy is insufficient for directly charging mobile phones and wearable devices, but it can supplement batteries to power some low-energy-consuming critical functions of the wearable device, especially in low-power consumption wearables. However, in an emergency scenario when the battery’s operational time is not sufficient or a battery charging source is unavailable, a solution is required to extend the limited battery span for mobile and wearable devices. This work presents the bottlenecks and new advancements in the commercialization of photovoltaics for smartphones and wearable technologies based on ambient light energy harvesting. A new technique, in which a smartphone cover is used as a solar concentrator to enhance light energy harvesting associa...

Moreover, the worldwide proportion of adults aged over 20 yr with a body-mass index (BMI) of 25 kg/m² or greater has increased between 1980 and 2013, from 28.8% (95% uncertainty interval 28.4-29.3) to 36.9% (36.3-37.4) in men and from 29.8% (29.3-30.2) to 38.0% (37.5-38.5) in women (1).
