This paper describes the humanitarian effort to help bring clean water and solar power to people in need along the Amazon River in Nauta, Peru. George Fox University partnered with JungleMaster Ministries to create a long-term development plan, beginning with a full prototype of the system at the NGO's house in Nauta. The engineering design, installation, and test of the system are discussed in detail,...
High-performance computing (HPC) is recognized as one of the pillars for further progress in science, industry, medicine, and education. Current HPC systems are being developed to overcome emerging architectural challenges in order to reach Exascale level of performance, projected for the year 2020. The much larger embedded and mobile market allows for rapid development of intellectual property (IP)...
Kernel-level Rootkit injects malicious code in the system kernel and realizes vicious function by modifying kernel code and data. The emergence of virtualization technology makes Rootkit hide itself and accesses system resources effectively. This paper proposes a kind of Rootkit based on VMM (VMRootkit) which can hide system process and system cannot find it. For realizing it, we firstly puts forward...
This paper presents implementation of a reactive base station selection scheme for millimeter-wave (mmWave) communications. In mmWave communications, the frame loss rate increases and the throughput sharply decreases when a pedestrian blocks a line-of-sight (LOS) path. To alleviate this human blockage problem, base stations can be selected so as to maintain LOS paths on the basis of communication...
Software-Defined Networking (SDN) is an emerging paradigm that arguably facilitates network innovation and simplifies network management. However, in the context of SDN, management activities, such as monitoring, visualization, and configuration can be considerably different from traditional networks. An SDN controller, for example, can be customized by network administrators according to their needs...
Through the information network recovery experience on the East Japan Great Earthquake on March 11, 2011, we learned that the combination of various existing wireless network technologies such as satellite IP network, 3G/LTE, Wi-Fi was useful in term of connectivity. In this paper, by integrating those wireless networks into a cognitive wireless network, user can use this cognitive network as an access...
Caregiving a person suffering from dementia or loss of brain cognitive ability due to aging is a big physical, mental and emotional burden to family members. In this paper we present a novel system for assisting caregivers at home. The system employs heterogeneous sensing and artificial intelligence technologies to automatically and unobtrusively monitor the patient; assess possible risks that the...
In an aging society, it is important to closely monitor elderly people, especially those with cognitive disorders, because they can easily fall down and sustain serious injuries. Therefore, the demand of the monitoring system which can detect dangerous situation automatically is increased. In this paper, we propose a low-cost and highly reliable monitoring device which is called the MIMAMORI device...
Prototype deployments of Software Defined Exchanges (SDX) have recently come into existence as a platform for Future Internet architecture to eliminate the need for core routing technology used in today's Internet. In this paper, we motivate the need for an adequate measurement architecture for such SDXes to be able to evaluate their performance and inform further development. We present the major...
The original design of the Internet did not take network security aspects into consideration, instead it aimed to facilitate the process of information exchange between end-hosts. Consequently, many protocols that are part of the Internet infrastructure expose a set of vulnerabilities that can be exploited by attackers. To reduce these vulnerabilities, several security approaches were introduced as...
In the lithium-ion batteries for an electric-drive vehicle, the cell balancing is required to enhance life time of batteries and to guarantee safety. In the vehicle-to-grid (V2G) system, batteries of electric-drive vehicle are more frequently charged or discharged, which increases probability of cell imbalance. Therefore, battery management system (BMS) with efficient cell balancing operation is necessary...
Virtual Machine Clusters tend to increase the amount of unused memory. We propose a remote swap management framework in a VM cluster which configures a remote swap dynamically to running VMs according to memory usage. We explain the functional requirements and the design of the framework, and demonstrate the effectiveness of the framework using prototype implementation.
This paper focuses on the design of wearable system operation modes in context of cooperation between personal healthcare systems. The patient is currently provided with telemedical solutions for home care and seamless diagnosis based on selected vital parameters. When two or more specialized systems are applied for monitoring of the same subject, the possible interference and cooperation are in question...
New tendencies envisage multiprocessor systems-on-chips (MPSoCs) as a promising solution for high performance embedded system. And the key challenge is how to improve the communication efficiency. Network on Chip (NoC) has been considered as a new paradigm in the next generation communication architecture for its scalability and power efficiency. A NoC prototype which consists of 8 ARM compatible...
Dependability is an important system attribute for microfluidic lab-on-chip devices. On-line testing offers a promising method for detecting defects, fluidic abnormalities, and bioassay malfunctions during chip operation. However, previous techniques for reading test outcomes and analyzing pulse sequences are cumbersome, sensitive to the calibration of capacitive sensors, and error-prone. We present...
Rapid prototyping allows for evaluation of design product in a short period of time. Designers or CEOs may perceive the size and appearance of the product by touching the automatically constructed physical objects produced through rapid prototyping. However, it is usually impossible to change its color, texture, and user interface. In this paper, we introduce 'Augmented Reality based Re-formable Mock-up',...
Datasets of tens of gigabytes are becoming common in computational and experimental science. Providing remote visualization of these large datasets with adequate levels of quality and interactivity is an extremely challenging task, particularly for scientists who collaborate in widely distributed locations and their primary access to visualization resources is a desktop computer. This paper describes...
