Ishibashi, Koichi; Nakai, Fuga; Yokotani, Tetsuya (Japan)
ABSTRACT:
Many researches and studies have discussed toward a smart society that brings richness to our lives by way of fusion of cyber space and physical space, based on utilization of information and communication technologies (ICT), at various places. So, in this paper, we focus to a large-scale smart street lighting system as an example of IoT services adopted on the IoT data exchange platform, and propose an architecture for efficient connection between gateways and collection by using a wildcard of data monitored by smart street lighting devices. Firstly, this paper explains an architecture of our proposed large-scale smart street lighting system, and proposes a data collection method by using a wildcard on Subscribe message. Secondly we introduce a novel evaluation metric for data correctness, called on freshness of data, and evaluate the communication traffic on the IoT core network as well as freshness of data on assuming linear decay of data correctness.

Endo, Yuji; Hashimoto, Shigehiro; Kageyama, Yoshisato; Morita, Yu; Yoshinaka, Kiyoshi (Japan)
ABSTRACT:
The effect of hysteresis of the tangential force field at the surface of the scaffold on the alignment of myoblast has been studied in vitro. The striped pattern (0.7μm height, 3μm width, and 3μm interval) were made on the surface of the scaffold plate to control the orientation of each cell. Variation was made on the angle between the longitudinal direction of the ridge and the direction of the tangential force: 0 degree, 45 degrees, and 90 degrees. C2C12 (mouse myoblast cell line) was used in the experiment. To apply the tangential force field (< 100 G) to the cells, the scaffold plate was set in the tube in a conventional centrifugal machine placed in an incubator. After the centrifugation for 5 hours, the behavior of each cell at the time-lapse microscope images was traced for 24 hours to analyze the angle between the longitudinal axis of the cell and the direction of the past centrifugation. The experimental results show that the tendency of cells to align the longitudinal direction of the striped pattern is strengthened by the hysteresis of the exposure to the tangential force field. The tendency is strengthened at the division of each cell.
An Algorithm to Differentiate Legumes and Wheat Based on Digital Image Processing and Support Vector Machine
Oshita, Angel; Parra, Ricardo; Vásquez, Edwin; Nuñez, Jossybel; Kemper, Guillermo (Peru)
ABSTRACT:
This work proposes a computational algorithm to differentiate five types of legumes and wheat using a support vector machine classifier (SVM). This tool is intended to provide a computational solution for automation applications that seek to differentiate or classify some types of legumes and cereal, in this case wheat. This automation is required for quality control, grain selection, sample statistics in laboratory analysis, or pedagogical use. This work’s main contribution is the selection of geometric and photometric descriptors that feed the SVM. The proposed algorithm first obtains an RGB, 24-bit color model image. Then, the image goes through a segmentation process consisting of thresholding, connectivity and labelling. Finally, the SVM classifies it according to descriptors that differentiate legumes and wheat. The validation process was carried out by visual inspection. An average result of 97% correctly identified legumes or wheat shows a very satisfactory performance of the proposed algorithm.
Application of Regression Analysis Towards Identifying Cyber-Attacks Upon a Smart Grid Augmented Electric Grid
Hopkins, Stephen; Kalaimannan, Ezhil; John, Caroline (United States)
ABSTRACT:
The Smart Grid integration with the existing grid provides increased benefits and risks to grid operation. These benefits and risks are driven by the distribution of power generation, integration of communication technology, and a more complex demand-response system. Smart Grid benefits include availability of end-user power generation, end-user income through provision of excess power, and the ability for the electric company to provide a more dynamic demand-response system. Disadvantages include the logistical integration complexity, lack of communication technology standards, cost of replacing analog meters, and increased exposure to cyber threats. Historically, the electric grid controls demand and response based on state estimation techniques. Many of these techniques include the ability to ignore measurement outliers, which are assumed to be erroneous data. The cyber-attacker can perform false data injection attacks, which escape the outlier detection and bias the state estimation. A robust cyber-resilient CPS includes sub-erroneous outlier detection, cyber-attack data weighting, cyber-attack data classification, state estimation cyber detection, and cyber aware state estimation. Previous and parallel studies are developing algorithms to perform the sub-erroneous outlier detection. The purpose of this paper is to evaluate the feasibility of simple linear regression to measure the performance of the sub-erroneous outlier detection algorithms.

Hishida, Hirotoshi; Yamamoto, Dai; Hishida, Keiko; Fujii, Yamato; Komatsu, Yoshihiro; Hishida, Yasuhiro (Japan)
ABSTRACT:
Some effects of music and sound flooding the streets on people are positive, such as music therapy, and others are negative, such as earphone hearing loss. In our laboratory, the authors are studying the construction of a data base for effective use of sound and music, while they are continuing to evaluate various effects of sound and music on humans quantitatively. After physically express sound and frequency analyses to Japanese nursery rhymes "Akatonbo" and Debussy's "Moonlight", the effects of music and sound were discussed, and the policy of the data base construction was proposed. These musics have the spectrum similar to that of natural sound, and make many people calm or refreshed. By constructing the data base, it is possible to calculate how much the earphone users are exposed to the sound energy from the information such as the music genre that the earphone users listen to.
Basic Concept of the Data Base on Music and Sound - II: Frequency Analysis to Beethoven's Piano Sonatas -
Hishida, Hirotoshi; Komatsu, Yoshihiro; Hishida, Keiko; Yamamoto, Dai; Hishida, Yasuhiro (Japan)
ABSTRACT:
In our laboratory, the data base of music and sound are constructing, and the 1st movement of Beethoven's Piano sonata No. 5 is added to it. Existing MIDI data was acquired from the Internet and was provided as the input data into the open source software which can count each pitch of tone. As the result, the histogram showing how many notes of each pitch were used in the music, which have the similar meaning to that of spectrum, was obtained. The data base is expected to be applied to various real problems while the lowest pitch could not be estimated accurately. The sonata can be thought as psychologically and physiologically pleasant music.
Basic Study on the Directivity in an Oblique Projection Drawing – The Influence of Time on the Directivity
Hishida, Hirotoshi; Fujii, Yamato; Hishida, Mitsuhiro (Japan)
ABSTRACT:
It is important to draw proper drawings in the engineering field because the vision is a sensation that is easy to illusion. The appropriate parameter set of the horizontal angle θ and the elevation angle ϕ on an oblique projection drawing are obtained in 2003. In this paper, the same cognition test was carried out to compare the result with that of previous one. Any noticeable difference was not found out and it is presumed that the parameter set is determined according by the sensibility which is common to all human beings.
Basic Study on the Mechanism of Earphone Hearing Loss – About Correlation between Ear Age and Real Age
Hishida, Hirotoshi; Fujii, Yamato; Kawano, Atsushi; Hishida, Keiko; Hishida, Yasuhiro (Japan)
ABSTRACT:
Young people around the world are at risk of earphone hearing loss. The authors have been continuing research on earphone hearing loss to elucidate its mechanism in this laboratory since 2010, and are trying to prevent them from it. In this paper, the earphone hearing loss test to 46 subjects are carried out to obtain the ear age compared with real age and the proposed ear deterioration index with which the effect of earphones is qualitatively evaluated. In addition, the authors asked the subjects their accumulated earphone usage time and their favorite genre of the sound source with simple questions to calculate the approximate accumulated sound energy they have received. For all the subjects, there was the linear tendency that the younger the real age is the worse the ear age is, and the ear ages of subjects under the age of 45 exceeded the real age. The ear degradation index tends to be worse as accumulated earphone usage time increased, and ear ages of junior high school boys aged 13 and 14 are remarkably bad. It can be the possibility that the earphone hearing loss could be clearly explained by the concept of fatigue fracture.
Basic Study on the Recognition of Height (Vertical Length) and Width (Horizontal Length) of Squares
Hishida, Hirotoshi; Komatsu, Yoshihiro; Hishida, Mitsuhiro (Japan)
ABSTRACT:
It is said that human vision has the tendency that the vertical direction is recognized as being longer than the horizontal direction. Such an erroneous recognition when reading the drawing may lead to trouble. In this study, the cognition test are performed on 100 subjects to find out if it was possible to correctly find squares from 49 different sizes of rectangles, each of which had 7 vertical and 7 horizontal lengths. In this paper, the results of the test using a sheet in which rectangles are arranged in 7 rows and 7 columns on A4 paper, and the width is increased from left to right and the height is increased from top to bottom, are described. Squares can be recognized correctly while there were some cases in which vertical rectangles were mistaken for squares.
Characterization and Analysis with xAPI Based Graphs for Adaptive Interactive Learning Environments
Streicher, Alexander; Pickl, Stefan Wolfgang (Germany)
ABSTRACT:
In e-learning, insights from the analysis of usage tracking data can help improve teaching and learning, e.g., with learning analytics to identify strengths and weaknesses of learners or course material, or for targeted help for individual students. One analysis approach is to examine the graph networks of interaction usages. Adaptive e-learning systems (ALS), which personalize the learning experience to the learners' needs, can make use of relationship information in graph networks to determine the best adaptation strategy. For example, ALS can use graph algorithms to detect central activities that have high influence to the users or to learning objects. This paper shows how to make use of the Experience API (xAPI) protocol and graph networks for its application in adaptive interactive learning environments such as computer simulations and serious games. A prototype implementation hints at the feasibility of the concept and its practical implications.
Cultured Myoblasts Orientation Under Couette Type of Shear Flow Between Parallel Disks: Fusion and Division
Endo, Yuji; Hashimoto, Shigehiro; Toma, Sora; Asahino, Akira; Yoshinaka, Kiyoshi (Japan)
ABSTRACT:
The effect of shear stress on myoblast has been investigated under the uniform shear flow in vitro. The culture medium was sandwiched with a constant gap between a lower stationary culture plate and an upper rotating parallel plate to make a Couette type of shear flow. The wall shear stress (τ) on the lower culture disk was controlled by the rotating speed of the upper disk. C2C12 (mouse myoblast cell line) was used in the test. After cultivation without flow for 24 hours for adhesion of cells on the lower plate, τ was continuously applied on cells for 7 days in the incubator. The behavior of each cell was traced at the time-lapse image observed by an inverted phase contrast microscope placed in an incubator. The experimental results show that cells make both division and fusion under shear stress < 2 Pa. Interaction between divided cells decreases with the distance between cells. The smaller cell tends to follow the bigger cell related to the alignment.

Furthermore, the technology selection method is a complex multicriteria decision problem that can be improved by a logical and organized approach to assess priorities based on the inputs provided by customers and the opinion of several people from different functional areas within the company. In this paper, some multicriteria decision methods are presented and compared. Some of the techniques analyzed are Vikor, AHP, ANP, Parametric model, Business Canvas, and Hub cities.
Design of Flow Channel for Cell Sorter by Dielectrophoresis with Photolithography Technique
Hashimoto, Shigehiro; Matsuzawa, Ryota; Endo, Yuji; Noji, Takeru; Yoshinaka, Kiyoshi (Japan)
ABSTRACT:
The flow channel for cell sorter in vitro has been designed by dielectrophoresis with photolithography technique. A pair of asymmetric surface electrodes of titanium (thickness of200 nm) were incorporated just before the branching flow channel: a triangular electrode with the tip angle of 0.35 rad, and a rectangular electrode of the flat edge as reference. The cyclic alternating electric current of the square wave (between 0.25 μs and 0.3 μs of periods) was introduced between the surface electrodes. The suspension of C2C12 (mouse myoblast cell line) was injected into the flow channel, and the flow rate was controlled by the pressure head between the inlet and the outlet. Experimental results of the pilot test show that the absolute value of the amplitude of the acceleration by the electric field, which is perpendicular to the flow direction, increases with the radius of the cell.
Development of a Flexible Educational Platform Based on a HIL System, Focused on Enriching the Teaching-Learning Process of Modern Control Engineering
Hamann, Franz; Martinez, Omar; Mesones, Gustavo (Peru)
ABSTRACT:
The present work proposes a low-cost educational platform based on a hardware in the loop system that allows incorporating a novel complementary alternative in the design of observers and controllers, since it allows to display various operating scenarios without the cost and time associated with the conventional physical tests, both for the simulated plant, and for the real controller. It seeks to provide the student with a tool that reduces the theoretical-practical gap corresponding to the study and development of controllers designed for the dynamic model of a specific plant, aiming to reduce the time the student spends when executing a laboratory experience even in 35%, replacing the process of programming from scratch the controller designed in the microcontroller with the possibility of configuring it quickly and efficiently through the graphical interface of the platform, so that the time saved in the implementation of the controller in the hardware is used to design, evaluate and compare a greater number of controllers whose characteristics and design complexity are different, thus allowing the student to consolidate theoretical knowledge more quickly in a practical environment improving the teaching-learning process. To achieve the objective, a communication protocol was programmed in C and Matlab so that, through a graphical interface, the student can easily configure both the software and the hardware section, which consists of a microcontroller PIC24FJ1024GB610 running at 16 MIPS, which was programmed to receive the control system configuration and execute the HIL control loop.
Hysteresis Effect of Shear Flow Field on Migration Velocity of Cell: After and Before Division of L929 and 3T3-L1
Hashimoto, Shigehiro; Shimada, Kosuke; Endo, Yuji; Yonezawa, Hiroki; Yoshinaka, Kiyoshi (Japan)
ABSTRACT:
The effect of shear flow field on the migration of each cell has been investigated under Couette type shear flow field in vitro. The culture medium was sandwiched with a constant gap between a lower stationary culture plate and an upper rotating parallel plate to make a Couette type of shear flow. The wall shear stress (τ) on the lower culture disk was controlled by the rotating speed of the upper disk. Two types of cells were used in the test: L929 (mouse fibroblast connective tissue), and 3T3-L1 (mouse fat precursor cells). After cultivation without flow for 24 hours for adhesion of cells on the lower plate, τ=1. Pa was continuously applied on cells for 7 days in the incubator. The behavior of each cell (before and after division) was traced at the time lapse image observed by an inverted phase contrast microscope placed in an incubator. The experimental results show that cells make division under shear stress of 1 Pa. Each cell makes wider variation of adhesion area (before and after division) in L929 than in 3T3-L1. Migration to perpendicular direction is more frequently at L929 than at 3T3-L1. Some cells of 3T3-L1 migrate downstream after division.

KIM-RPA: An on Background Knowledge Based Framework for the Agile Implementation of Smart RPA Use-Cases in Business Applications Context
Angermann, Heiko; Hänisch, Till (Germany)
ABSTRACT:
Robotic Process Automation (RPA) has experienced high attention in recent research on Artificial Intelligence (AI) and related paradigms. The future of RPA lies in Smart RPA. This means that not only lower complex work is automated using RPA, but also the automation of context-based human repetitive work should be possible. In the paper at hand, the framework named KIM-RPA for the agile implementation of Smart RPA use-cases is presented. Contrary to existing approaches, KIM-RPA makes use of background knowledge, and provides an architecture for the flexible integration of various internal and external knowledge resources (formal ontologies, informal knowledge), as well as different algorithms. The paper describes the proposed framework, and a case-study will show its agility.
Man-Machine Synergy Algorithms for Homeland Protection
La Manna, Mario (Italy)
ABSTRACT:
Homeland Protection systems include a variety of systems, from critical infrastructure protection, transport and territory protection, secure communications, border control, and other relevant applications. The complexity of each of these systems requires a multidisciplinary approach, in order to deal with different agents and to merge different technologies. This approach is basically constituted of automated mechanisms, relying on machine learning techniques, and on human judgment, based on human agent/intelligence techniques. As a whole, an advanced security system for Homeland Protection is constituted of a set of sensory elements, enhanced by artificial intelligence, and on human agent/intelligence elements, cooperating with each other. This paper proposes a set of novel algorithms, based on the general concepts of detection theory processes and decision processes and on the balanced synergy between all the above processes. From the examination of some case studies, we demonstrate that the man-machine synergy approach is particularly suited to enhance the security level in Homeland Protection tasks.
Micro Back-Markers on Thin Film of Scaffold to Measure Repetitive Local Contraction of Myotubes in Vitro
Hashimoto, Shigehiro; Saito, Yuta; Endo, Yuji; Shinoda, Shun; Toyota, Shouki; Yoshinaka, Kiyoshi (Japan)
ABSTRACT:
The repetitive contraction of myotubes has been measured by the local movement of micro-markers on the thin film of the scaffold under the electric stimulation in vitro. The scaffold is made of a thin polydimethylsiloxane film (thickness of 6 µm), of which the back side has arrangement of micro-protrusions (4 µm diameter, 2 µm height, interval 30 µm) made by the photolithography technique. C2C12 (mouse myoblast) was seeded on the film at the counter surface to the protrusions at the density of 50000 cells/cm2. The cells were cultured to be differentiated into myotubes on the scaffold for 12 days in the medium containing 10% FBS (fetal bovine serum) and 1% penicillin/ streptomycin in the incubator. The electric pulses (amplitude of 30 V); pulse cycle of 1 s; pulse width of 1 ms) were applied between electrodes of titanium wire dipped in the medium. The contraction of myotubes is observed through the transparent scaffold at the microscope. The experimental results show that the amplitude of the cyclic variation of the distance between micro-markers depends on distance and on alignment. The designed scaffold has a potential to analyze the local contractile movement of the layer of myotubes in vitro.

Thanapalan, Kary; Constant, Ewen (United Kingdom)
ABSTRACT:
This paper presents an overview of energy storage technologies for excess renewable energy production. In particular, wind and solar energy systems are investigated. A case study was conducted for a self-sustainable energy system configuration to realise the impact and the importance of a suitable energy storage system. The issues relating to such a system design is investigated using a specific application and the performance of the system under variable conditions are determined. From the results and analysis, it is clear that the batteries are still best option for self-sustainable renewable energy systems. However, large-scale systems may require alternative storage mechanism such as P2G methods.
Proposal of Traffic-Light Detection Scheme Based on Online Map Images
Naito, Katsuhiro; Ono, Ryota; Mori, Yuki (Japan)
ABSTRACT:
Intelligent Transport Systems have been attracted attention. Since the increase in demand for green mobility, the improvement of traffic efficiency is also required. The initial research has proceeded to evaluate the optimization scheme for traffic in simulations. Recently, more real evaluation is required to optimize some parameters or to evaluate traffic characteristics in a real environment. Especially traffic-lights affect traffic in a real environment. However, the position of traffic lights in the real world is not opened for researchers even if the position of an intersection with traffic-lights is required to perform evaluate traffic in the real environment. This paper proposes a traffic-light detection scheme based on online map images. Recently, some companies provide map service for consumers. Typically, this map includes an accurate existence of traffic lights. The proposed scheme can detect a traffic-light icon on online map images to obtain a location of an intersection with traffic-lights. The output of the proposed scheme can be used for actual simulations with a real map. The evaluation results show that the proposed scheme can detect a traffic-light icon with more than 98% accuracy.
Scoring Sentiment by Combining Emojis and Slangs in Social Media
Yu, Songmei (United States)
ABSTRACT:
The Web has dramatically changed the way people express their views and opinions. Recently we have seen more and more people use Emojis and/or Slangs in social media to express emotions and preferences. Sentiment analysis refers to the task of identifying opinions, favorability judgements, and other information related to the feelings and attitudes in natural language tests. Sentiment analysis in social media has become an increasingly important research topic. Although textual sentiment analysis has been well studied based on platforms such as Twitter and Instagram, analysis of sentiment by combining extensive use of Emojis and Slangs remains light. In this paper, we present a novel approach for finding the sentiment score of social media contents by analyzing both Emojis and Slangs in the content, and comparing the score with the traditional sentiment score detected from the textual content. As the result of experiment, our proposed method provides an effective way to supplement the text-based sentiment analysis.
Tracings of Myoblasts Orientation Under Shear Flow in Vitro
Hashimoto, Shigehiro; Kimura, Kento; Endo, Yuji; Sakai, Michitaka; Yoshinaka, Kiyoshi (Japan)
ABSTRACT:
Myoblast orientation under the flow has been investigated under the uniform shear flow in vitro. The culture medium was sandwiched with a constant gap between a lower stationary culture plate and an upper rotating parallel plate to make a Couette type of shear flow. The wall shear stress (2 Pa) on the lower culture disk was controlled by the rotating speed of the upper disk. C2C12 (mouse myoblast cell line) was used in the test. After cultivation without flow for 24 hours for adhesion of cells on the lower plate, the constant shear stress was continuously applied on cells for 7 days in the incubator. The behavior of each cell was traced at the time-lapse images observed by an inverted phase contrast microscope placed in an incubator. The experimental results show that each single cell tends to align parallel to the flow direction under shear stress of 2 Pa. The mean direction of cells in some colonies of C2C12 tends to align perpendicular to the flow direction.
Typical Applications of Unmanned Aerial Vehicles: Opportunities and Challenges
Ilyas, Mohammad (United States)
ABSTRACT:
Research interest in unmanned aerial vehicles (UAVs), also referred to as drones, has been steadily surging over the past several decades. With the advances in hardware, software, and communication technologies, the size of UAVs is shrinking and thus many applications are emerging. The applications of UAVs are anticipated in almost all fields including healthcare, agriculture, energy, search & rescue, transportation, surveillance, and even in communications to extend the reach of Internet. Some of the applications may require a group of UAVs to work together in a coordinated manner. In general, all UAV operations need to be sophisticated, smart, and autonomous. This is particularly so for coordinated operations that involve multiple UAVs. The opportunities and emerging applications of UAVs are numerous and so are the challenges. This paper discusses some of the typical applications of UAVs, opportunities they provide, and some of the challenges they pose. The paper also discusses the role of artificial intelligence in smart operations of UAVs.

Hashimoto, Shigehiro; Matsumoto, Taku; Endo, Yuji; Kuwabara, Shono; Yonezawa, Hiroki; Yoshinaka, Kiyoshi (Japan)
ABSTRACT:
The velocity change of a flowing cell near the oblique micro groove on the bottom surface in the micro flow channel has been measured in vitro. The micro groove of the rectangular shape (4.5μm depth, and 0.2mm length) has been fabricated on the polydimethylsiloxane (PDMS) disk by the photolithography technique. The angle between the flow direction and the longitudinal axis of the groove is 45 degree. Variation has been made on the width (0.03 mm, 0.04 mm, and0.05 mm) of the groove. A rectangular flow channel (0.05 mm height× 1mm width×25 mm length) has been constructed between two transparent PDMS disks. In the test, malnourished C2C12 (mouse myoblast cell line) was used in comparison with the normal C2C12.A flow velocity (0.02mm/s <vx< 0.23mm/s) of the suspension of cells was controlled by the pressure difference between the inlet and the outlet. The change of the velocity (perpendicular to the main flow direction) of each flowing normal cell at the oblique groove is higher at the slower flowing velocity on the wider groove.
Video Summarization Using Deep Action Recognition Features and Robust Principal Component Analysis
Claborne, Daniel M.; Pazdernik, Karl T.; Rysavy, Steven J.; Henry, Michael J. (United States)
ABSTRACT:
In an instance where desired pre-defined actions, behaviors, or other categories are known a priori, various video classification and recognition models can be trained to discover those classifications and their location within the video. Absent that information, one might still be tasked with identifying interesting portions within a video, a process which—if done manually—is onerous and time-consuming as it requires manual inspection of the video itself. Recognizing high-level interesting segments within a whole video has been a general area of interest due to the ubiquity of video data. However the size of the data makes storage, retrieval, and inspection of large collections of videos cumbersome. This problem motivates the task of generating shortened clips highlighting the primary content of a video, relieving the burden of having to watch the entire video. This paper presents an unsupervised method of creating shortened clips of videos, enabling the rapid review of the most interesting content within a video. Our method uses features extracted from pre-trained action recognition models as input to online moving window robust principal component analysis to generate summaries. The procedure is tested on a publicly available video summarization dataset and demonstrates comparable performance to state-of-the-art in an un-augmented setting while requiring no training.
