The trend "Internet of Things" (IoT) equips Objects with a Internet connection in order to let people benefit from this interconnectivity. We propose a concept which is not only about the interconnectivity of Objects but mainly how we could easily enhance our usage of Objects through data. The investment into omnipresent Internet-capable devices is not reasonable in every scenario. Our goal...
The secure deployment of an application requires the definition of the security properties that it should meet. This is typically performed on the basis of a security policy, which aims at providing a concrete view of security requirements to the application developer. In this paper, we propose a framework to manage security policies that could be associated with applications based on an AOP approach...
Multimedia services are typically much more sensitive to throughput, delay, and packet loss than traditional services. These parameters do not reveal the quality of service (QoS) perceived by users. This paper designs and implements a Quality of Experience (QoE) measurement framework to capture users' perceptions. The concept of framework is first to create a sample database in the analysis center,...
This paper conceptually proposes a context-aware recommendation system that gives/recommends optimal information for users based on 1) the content of an image using content-based image retrieval engines, 2) the contextual information of its similar images on the Web, and 3) user context, namely users' situations such as their location, we are aiming to extract the detailed information to the text-unpresentable...
An Automated Recognition Technique for Lung Vessel Tree (ARTLVT) was proposed. ARTLVT was a one of 3-dimensional processing techniques, and had a recognition engine named Successive Region Growing (SRG). ARTLVT automatically found a cross-section of trachea from multi-slice CT images of hundreds. ARTLVT applied SRG to the cross-section and extracted trachea, bronchi and both lung fields. Based on...
This paper proposes the proportional image enlargement using hybrid methods. Hybrid method is combinations of scaling and carving methods. This method consists of two steps. The first step enlarges the source image to the same size with minimum size for height or width from the target image. In this step, we use a kernel scaling method which is resulted in proportional content image size. The second...
Needs and offers assessment and matching system can be an essential component of the recovery of the communities to recover from the aftermath of natural disasters. In this paper we present the design of a framework called SPADE (Social Platform for After-Disaster matching of Emergent needs and offers) that leverages on the capacity of self-organization of communities of actors involved in crisis...
Growing numbers of consumer entertainment devices such as game consoles and other portable game devices are seeing increased utilization as Internet As such these devices do face the same online threats experienced by other more familiar networked devices such as personal computers, either directed or indirect. Unlike mature personal computing devices, few, if any, software applications exist to provide...
Patient specific instruments (PSI) system has been attracting considerable attention for navigation-free surgical operation of total knee arthroplasty (TKA). PSI is a jig which guides a cutting section of the femoral or the tibia bones where TKA implant is attached to ensure accurate and reproducible surgery, and is prepared for a specific patient. However, another problem has been raised because...
The paper presents a novel bone-conduction based brain-computer interface paradigm. Four sub-threshold acoustic frequency stimulus patterns are presented to the subjects in an oddball paradigm allowing for "aha-responses" generation to the attended targets. This allows for successful implementation of the bone-conduction based brain-computer interface (BCI) paradigm. The concept is confirmed...
During an emergency, the situation can change rapidly and emergency information is crucial to evacuate people safely from buildings. The guidance system we use during emergencies should be the same as those used in everyday life. Nowadays, almost everyone has a mobile phone. A guidance system using smartphones can provide more useful information than guideboards on walls or announcements. We propose...
In this paper, some limitations about Earthquake Early Warning (EEW) were examined, which had become apparent during and after the 2011 off the Pacific Coast of Tohoku Earthquake. The proposal system analyzes automatically correcting a detection error when server gets earthquake information more than magnitude M7.5. The estimation method for embankment settlement is performed using "Damaged Tables"...
This paper discusses a method to extract character strings from scene images. In this method, the Canny edge detector is first applied to a scene image, and the binary edge image is then obtained. Next, small edge elements are separated from large edge elements because edge elements from characters are much smaller than edge elements from non-character objects such as signboards etc. However, many...
Comparison of anatomical or functional parameters is common theme in the evaluation of unilateral pathologies of the human knee joint, although the degree of bilateral symmetry is unknown. Currently, the evaluation is performed manually. Therefore, diversity of the evaluation happens due to the subjective judgment. To reduce the diversity, we propose an automated analysis method for anatomical knee...
When doctors make a decision of a treatment for recurrent patellar subluxation, they diagnoses the patello-femoral joint with palpation and medical images. As the problems of diagnosis, the results depends on their experience and medical knowledge. It results in divergences of diagnosis results. In addition, three dimensional analysis requires massive labor and time for them. Therefor the goal of...
Indirect immunofluorescence imaging is employed as a standard method to detect antinuclear antibodies in HEp-2 cells which is important for diagnosing autoimmune diseases and other important pathological conditions involving the immune system. HEp-2 cells are generally categorised into six groups: homogeneous, fine speckled, coarse speckled, nucleolar, cytoplasmic, and centromere cells, which give...
The presented study explores the extent to which tactile-force stimulus delivered to a hand holding a force-feedback joystick can serve as a platform for a brain-computer interface (BCI). The four pressure directions are used to evoke tactile brain potential responses, thus defining a tactile-force brain computer interface (tfBCI). We present brain signal processing and classification procedures leading...
The aim of this study is to provide a comprehensive test of head related impulse response (HRIR) for an auditory spatial speller brain-computer interface (BCI) paradigm. The study is conducted with six users in an experimental set up based on five Japanese hiragana vowels. Auditory evoked potentials resulted with encouragingly good and stable "aha-" or P300-responses in real-world online...
This paper explores the relationships between migration and trade using a complex-network approach. We show that: (i) both weighted and binary versions of the networks of international migration and trade are strongly correlated, (ii) such correlations can be mostly explained by country economic/demographic size and geographical distance, (iii) pairs of countries that are more central in the international-migration...
Twitter is a web 2.0 social network which attracted much attention recently for its usage as an alternative media for information diffusion. From the recent events in arab countries, to natural disaster such as earthquakes or tsunamis, Twitter has proven to be a credible alternative to traditional means of information diffusion. Relatively few works have been done on this question of information diffusion,...
