Mobile devices have been increasing in both number and power. While devices such as smartphones gain capabilities, an increasing number of users rely on them to complete more and more tasks. One of the most significant constraints of mobile devices is the necessary reliance on battery power. This limitation can be circumvented by operating the device while it is charging; however, this approach has...
Proposals and some implementations of Internet of Things (IoT) systems for healthcare are described. Implications of current European Union legislation, the new General Data Protection Regulation, for the security and reliability of healthcare IoT systems and for the privacy of users of these systems are presented. Analytics of healthcare IoT data for the requirements of evidence based healthcare...
The optical network management system is very important for optical equipment monitoring and managing, the timeliness and accuracy are very critical parameters. Automatic discovery of network nodes is the embodiment of automation of network management system. However, most of the traditional automatic discovery method is based on the ICMP protocol, which is to ping all the IP addresses in local area...
When a device on network communicates with copious other devices during a time window, this device is called a super point. Super points play important roles in network because they are usually servers, hosts running P2P applications, worms, DDos victims. Super points may change with the time. How to locating these super points from core network efficiently is a hard task. This paper proposed an algorithm...
Information technologies can assist the elderly in their daily lives and thus improve their quality of life. Here, we present a system that was developed within the framework of the EU H2020 project IN LIFE to make the elderly feel more secure. The system consists of a smartwatch, a tablet, and a web portal for carers. The smartwatch has several functionalities; the most important are automatic fall...
Detecting RAT (Remote Access Trojan or Remote Administration Tool) used in APT (Advanced Persistent Threat) attacks is a challenging task. Many previous methods to detect RATs on the network require monitoring all network traffic. However, it is difficult to keep all network traffic because the size is too huge. Actually, we would have to detect RAT activity through insufficient information such as...
Wildfires, often dubbed megafires, have in recent times increased in both frequency and scale, owing largely to human error as well as climate change. Due to their uncontrolled unpredictable rapid growth and behaviour, they can quickly become difficult to contain, leading to significant loss of lives, wildlife and property. It is therefore critical to tackle such fires in the early stages. This demands...
From process formulation, welding production to quality inspection, welding quality management needs the cooperation of many departments. In actual production, the repeated works, omissions, and other problems of the establishment of welding procedure specification (WPS) occur from time to time. Dynamic changes of welding current and voltage signals can reflect the performance of electric arc; unstable...
Pollution has become an environmental concern that has put the prospects of a sustainable future at risk. Though technology is advancing at a rapid rate but the question of an eco-friendly living remains unanswered. With growing population figures, the transportation requirement is increasing at a significant rate but the vehicular pollution arising from surface transport has serious health hazards...
In the continual battle between malware attacks and antivirus technologies, both sides strive to deploy their techniques at always lower layers in the software system stack. The goal is to monitor and control the software executing in the levels above their own deployment, to detect attacks or to defeat defenses. Recent antivirus solutions have gone even below the software, by enlisting hardware support...
In this paper, a data-center network (DCN) system that distinguishes Hadoop job types and allocates optical/electrical circuits to data flows depending on the types automatically is proposed. The proposed system calculates the predicted shuffle value (PSV) of the Hadoop job and determines which type of flow is allocated by comparing the PSV and the threshold value. The PSV can be calculated from a...
Internet of Things (IoT) has facilitated integration of wireless communication capabilities into sensing devices. IoT enables monitoring of many electrical, physical and environmental parameters. Electrical power consumption is one of such important parameters to be monitored. In literature, many power monitoring devices have been proposed for this purpose. But they are expensive, complex and lack...
In the past years, the Philippines recorded different disasters in diverse parts of the archipelago. The most frequent natural disasters were floods and storms that bring hazards to the people. The country has high level of exposure to hydro-meteorological hazards due to its geography. Because of the frequency, intensity, and variability of the hazards the government is compelled to adopt disaster...
Wind-flow around a long-span bridge, as a bluff body, will generate an aerodynamic force that interacts with the flow, causing vibration to the bridge deck. This phenomenon can lead to structural fatigue or worst, the bridge collapse. A continuous and comprehensive measurement system is needed for early detection and maintenance reference of a long-span bridge. Another benefit this system is aiming...
Nowadays, the many traffic information are extracted from CCTV. The road occupancy, vehicle speed, accident detection, traffic collision and weather information are calculated in CCTV. These are big data comes from varying sources, such as, social sites or mobile phone GPS signals and so on. The Hadoop and HBase can store and analyze these real-time big data in a distributed processing framework....
The capability of prognostics and health monitoring of spacecraft such as satellites and spaceships is of key importance for their correct operation and the success of their mission. Before launching, various experiments are usually carried out on the spacecraft to thoroughly examine its performance and reliability, resulting in a large amount of experiment/test data. During its operation in orbit,...
We have proposed an introductory C programming exercise based on contest style using execution test series. We have developed a contest management server tProgrEss and have carried out educational practices since 2009. We developed an Instruction support tool vRoundEd in classroom round during a contest. The tool is for teaching assistants with each tablet PC. It shows a seat map in classroom and...
Due to the high cost and high power consumption problem of the present smart home server, we designed and implemented a home server based on embedded system, mainly developed by ARM11 for a hardware platform, Linux system for operating system, SQLite database and BOA server for a software platform. The home server has successfully implemented the network communication, SQLite database peration and...
For the elderly, the sub-health crowd, the insomnia people groups, the vital signs real-time monitoring system can realize real-time monitoring of sleep quality and heart rate changes. The concentrated and effective management (assessment, prediction and control) for the sleep state of sub-health crowd and community residents can realize early monitoring, early detection, early diagnosis and early...
Classification of remote sensing images often use Support Vector Machines (SVMs) that require an n-fold cross-validation phase in order to do model selection. This phase is characterized by sweeping through a wide set of parameter combinations of SVM kernel and cost parameters. As a consequence this process is computationally expensive but represents a principled way of tuning a model for better accuracy...
