This paper aims to develop a multisensor data fusion technology-based smart home system by integrating wearable intelligent technology, artificial intelligence, and sensor technology. We have developed the following three systems create an environment: (1) motion sensing device be placed on residents' wrists its corresponding 3D gesture recognition algorithm implement convenient automated household appliance control system; (2) mounted resident's feet indoor positioning realize effective...

Quorum-based mutual exclusion algorithms are resilient to node and communication line failures. Recently, some successfully use logical structures construct coteries with small quorums sizes. In this paper, we introduce a geometric approach on dealing the present useful properties for constructing k-coteries. Based those properties, structure named three-sided graph is proposed provide new scheme quorums: The smallest quorum size O(/spl radic/N) in homogeneous system N nodes O(1)...

This study was to translate the Pieper-Zulkowski pressure ulcer knowledge test (PZ-PUKT) into Traditional Chinese and evaluate its psychometric properties as well identify predictors of on injury. The PZ-PUKT translated (TC-PZ-PUKT), content validity evaluated. A total 296 nurses participated in this completed 72-item TC-PZ-PUKT online. reliability analysed by evaluating internal consistency test-retest reliability. Hierarchical regression used determine factors associated with scores....

We propose a structure named Cohorts to solve the problem of access control multiple entries critical section. Our solution is formalized as forming quorums in k-coterie. It resilient node failures and/or network partitioning, invokes constant expected message cost and has comparably high availability.

The authors extend the concept of coterie into k-coterie for k entries to a critical section. A structure named Cohorts is proposed construct quorums in k-coterie. solution resilient node failures and/or network partitioning and has low communication cost. further improved increase availabilities 1-entry sections.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Purpose Focusing on social network services (SNS), the purpose of this paper is to propose a research model investigate individuals’ SNS usage facilitators and inhibitors from perspective media system dependency (MSD) privacy concerns. Design/methodology/approach The will be tested with data collected online users Facebook. survey yielded total 403 responses for analysis which was conducted by measurement structural models. Findings findings indicate that SNSs members strive understanding,...

COVID-19 has resulted in the increased use of distance learning around world. With advancement information technology, traditional classroom teaching gradually integrated Internet and methods. Students need to be able learn on their own a environment, so ability self-regulate environment cannot ignored. However, previous studies self-regulated learning, most learners alone. When they have academic doubts, obtain help support from studies, resulting reduced outcomes. This study uses peer...

This paper presents a self-designed wearable inertial sensing module and its associated drift modeling compensation algorithm to obtain drift-removed signals for handwriting trajectory reconstruction. Users can utilize the write numerals at normal speed, which consists of microcontroller, triaxial accelerometer, uniaxial gyroscope, biaxial an RF wireless transmission module. The accelerations angular velocities generated by movements are transmitted computer via In order minimize integral or...

The objective of this study is to develop a multi-sensor data fusion technology based smart home system and its intelligent monitoring interface. functions include: 1) entertainment household appliances remote control; 2) indoor positioning energy management; 3) fire prevention. In addition, an interface developed for the provide environmental temperature, CO concentration, communicative alarm, situation, human motion signals, results gesture classification in real-time. Finally,...

Flipped classroom is one of the important teaching modes among many novel methods in recent years, students watch video pre-class. However, if cannot focus on pre-class learning or have problems with content, effect will be less than expected. Therefore, this research proposes a flipped combined WPAQ model extended by WSQ to carry out programming courses, allowing perform peers online before class and jointly complete tasks lists, share them summary content enhance effectiveness. The results...

Abstract This paper analyses the relationship between entrepreneurship and an industrial cluster in general, by particularly examining one of Taiwan's clusters, Houli's saxophone cluster. Our purpose is threefold. First, instead investigating high-profile chiefly government-directed such as science parks, we focus on a small medium enterprise (SME) Second, unlike most studies that usually show how clusters foster entrepreneurship, emphasize role formation industry. We discuss skilled artisan...

The asynchronous PS (Power-Saving) protocol was designed to synchronize two wireless hosts in the ad hoc network such that those can transmit an unicast message even though they have wakeup frequencies. However, for transmitting a multicast more than one receiver, could not guarantee all receivers wake up simultaneously and then receive message. In this paper, we propose new protocol, named CRT-MAC transmission networks. We define difference m-pair property m different frequencies...

Wireless time signal broadcast system is an essential platform for the operation of radio watches. It also a good broadcasting other civil information such as disaster warning. To obtain wide coverage area, carrier frequency usually low tens kHz. When designing receiver front-end IC's in this low-frequency range, noise consideration critical. In paper, design low-power, low-noise IC 0.35 μm SiGe BiCMOS technology reported. The tolerates input dynamic range 106 dB and has high sensitivity....

Now the context-aware learning has been hot subject for many scholars to explore in e-learning. In learning, learners interact with environment stimulate learner's emotion. Learners will be immersed thus enhance their performance. However, most of had discussed interaction between learner and environment. fact, emotion is a more important factor than affect Hence we want design system that uses physiological sensors recognize learner. The adjust level give suitable aids according so can have better

The AODV routing protocol, which is simple and efficient, often used in wireless sensor networks to transmit data. protocol constructs a path from the source node, detects target, sink node. Whenever target moves, will be reconstructed RREQ packet broadcasted flood network. localization repair sets up reconstruction area restricts broadcast of that avoid storm. However, this method cannot reconstruct once moves out area. In paper, we propose lightweight for mobile detection. When breaks...
