Wireless remote patient monitoring has the scope to improve patient experience while enabling data transmission to support effective patient care. Dash7 and ZigBee are potential wireless technologies which can facilitate this. Dash7 or ZigBee, when integrated with a mobile phone accompanied by the patient, can overcome the problem of range limitation imposed by traditional wireless patient monitoring...
This study aims to examine the environmental factors that determining membership trust and the relational outcomes for both the professional association (PA) and its members. The conceptual model and hypotheses are tested by the partial least square (PLS) technique based on survey data provided by 219 professionals from a variety of PAs in Taiwan. The findings show that trust is a significant mediator...
Dense Heterogeneous Network is one of the key features of 5G. The base station sleep technology has become the focus of attention in mobile communication for its good performance in energy efficiency. In this paper, we propose an Intra-Cluster CoMP based Sleep-mode Scheme (ICCSS) which further improves the energy efficiency in Dense Heterogeneous Network. First, we divide dense small cells into different...
IEEE802.11 which is widely used wireless LAN standard, degrades its broadcast performance by existence of hidden terminals. Then, we have proposed RTB–DR (RTS/CTS for Broadcast with Directional Receiving) for improving broadcast performance on single hop situation. RTB–DR can effectively improve receiving performance by introducing directional antenna while keeping simplicity of transmission sequence...
The main novelty of this paper is presenting the implementation of GDL classifier in pure Lua language. We also present the evaluation of this implementation for motion capture data classification in real-time and compare the execution time with GDL 1.1 implementation. The experiments showed that Lua implementation performance of GDL in most cases is several times slower than managed C# GDL script...
Some black-box testing methods utilize memory update frequency to solve the difficulty of fault localization during system integration testing for automotive software. They need memory information, but the strict test policies and environments don't allow to use existing debugging tools. The proposed data cascading algorithm could deliver large memory information within the limited bandwidth. However,...
Conflicting rules and rules with exceptions are very common in natural language specification to describe the behaviour of devices operating in a real-world context. This is common exactly because those specifications are processed by humans, and humans apply common sense and strategic reasoning about those rules. In this paper, we deal with the challenge of providing, step by step, a model of energy...
In our previous work, it has been shown that the students can improve the learning process by using smartphones. The professors of the university cannot provide the information to satisfy all students because the quantity of knowledge of each student attending a lecture is different. Therefore, for the lectures of a higher level than intermediate level, the students should study the learning materials...
It is now critical to reduce electric energy consumed in a cluster of servers, especially scalable systems like cloud computing systems. In clusters, most application processes like web applications use not only CPU but also storages like databases. In this paper, we consider storage processes which read and write data in files in addition to computation processes. We propose an MLPCMS (power consumption...
Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers. Node placement problems have been investigated for a long time in the optimization field due to numerous applications in location science. In this paper, we evaluate the performance of two WMN architectures considering throughput, delay, jitter and fairness index metrics. For simulations, we used ns-3...
In this paper, we present the mobile autonomous underwater vehicle (AUV)-aided efficient localization scheme for underwater wireless sensor networks (UWSNs). Localization is one of the major issues in UWSNs as it is important in some large scale applications to know the accurate position of sensor nodes. It is more difficult to localize a node in underwater environment compared to terrestrial. The...
For C++ programs often appear memory leaks, cross-border access memory and memory does not match the release of error, we have analyzed existing memory error detection tools and methods, implemented in the Linux platform to run the memory testing tool MemDetect prototype based on the open source dynamic instrumentation-Valgrind using function family's memory information block management method and...
