title: Computer-aided liver diagnosis by integrating information of shape and hardness derived from MRI
abstract: Techniques currently used for definitive diagnosis of liver fibrosis are invasive and burden to the patient is high, thus non-invasive techniques are preferable. In our previous study, we reported a method that classify presence of liver fibrosis from information about the liver shape. The purpose of this study was to integrate information of shape and hardness obtained by magnetic resonance elastography (MRE) to aid diagnosis of liver fibrosis. In order to integrate the information of shape and hardness, we need to automatically segment the liver in MRI at MRE acquisitions. In MRI, non-uniformity of the intensity is unavoidable even in the same tissue due to its imaging principle. Therefore, conventional automated segmentation method in CT were less accurate in most cases. As a first step of my study, automated segmentation of the liver from MRI with the intensity correction is implemented and tested. language of the presentation: Japanese 発表題目: MRIにおける肝臓の形状と硬さ情報を統合した診断支援に関する研究 発表概要: 現在，臨床で肝線維化と呼ばれる肝臓疾患の確定診断に用いられる方法は侵襲的であり患者への負担が大きく，非侵襲な手法が求められている．我々のグループでの以前の研究では，肝臓の形状情報から肝線維化の有無を分類する手法が報告されている．本研究では，肝線維化診断の支援のため，形状情報とMRエラストグラフィ（MR elastography：MRE）から得られる肝臓領域の硬さ情報を融合することを目的とする．形状と硬さの情報を統合するため，前提条件としてMRE撮影時に得られるMRIからの肝臓領域の自動抽出を行う必要がある．MRIは，撮像の原理上同じ組織内でも濃淡むらが発生するため，既存のCTの自動抽出法は精度が不十分になる場合が多い．研究の前実験として，MRIの濃淡むらを補正した肝臓の領域抽出法を実装しテストした． | ||

title: Detection of outlier trajectories in evacuation guiding system using trajectories of mobile terminals.
abstract: In my laboratory, we are developing the evacuation guiding system using trajectory information (consisting of a sequence of the GPS locations) collected from evacuees’ mobile terminals. This system estimates impassable roads from the difference between the evacuation route that mobile terminal has presented (recommended route) and the route that each evacuee has been actually through (movement trajectory). At this time, the estimation method does not work correctly if there are evacuees who do not move according to the recommended route. Then, I am considering estimation methods for automatically detecting trajectories that the system intends them not to pass through. In this presentation, I introduce the existing methods for detecting outlier trajectories and similar trajectories each other from many of trajectory information. Moreover I describe a prospect of how to apply the method to the system that we are developing. language of the presentation: Japanese 発表題目: 端末の移動軌跡情報を用いた避難誘導システムにおける異常軌跡の検出手法 発表概要: 現在発表者の研究室では、災害発生時に避難者のモバイル端末から収集した移動軌跡情報（GPS位置データの列）を用いて避難誘導を行うシステムの開発を進めている。このシステムでは、モバイル端末が提示した避難経路（推薦経路）と実際の避難行動（移動軌跡）との差から通行不能な道路の推定を行う。このとき、推薦経路と異なる目的地へと移動する避難者が存在すると推定方式が正常に動作しなくなる。現在、このようなシステムが意図しない軌跡情報を自動的に検知するための推定方式について検討を進めている。本発表では、多くの軌跡情報から互いに類似した軌跡や平均から外れた軌跡を検出する既存方式を紹介するとともに、我々の想定するシステムへの応用に関する展望を述べる | ||

title: Multi-server queue with job service time depending on a background process
abstract: One of approaches to the reduction of power consumption for data centers is to power down part of servers according to the temperature inside a data center or the total amount of power consumption. In this research work, we consider a multi-server queueing system for distributed parallel processing over groups of servers, in each of which part of servers are turned off. We model the system as an M/G/c-like queue, where each job service time depends on the state of a background process when it starts. We derive the joint distribution of the number of jobs in system and the state of the background process. In numerical examples, we quantitatively investigate how the state-transition rate of the background process and the service rate affect the mean job response time. language of the presentation: Japanese | ||

Title: Test Algorithm Generation for Neighborhood Pattern Sensitive
Fault in Memories
Abstract: Memories are the most dense components in large scale SoCs, accounting for more than 50 percent of the chip area. Therefore, testing of memories is essential to maintain a quality and reliability of the products. The Neighborhood Pattern Sensitive Fault (NPSF) is widely discussed fault model, and is becoming more and more important, with increasing density of the memory chips. However, test for NPSFs have been manually created and it does not always allow to obtain an optimal solution. We investigate a new approach that systematically generates a test for NPSFs.

| Title : Distraction-less Realtime Feedback Visualisation in Sports Training Abstract : In this research, we explore a new approach to feedback visualisation for self monitoring during sports training. Although providing post-workout statistical feedback about the performance of users still tends to be the common way, it lacks the ability to support them during the actual training. This deficiency causes users to have brief pauses and diverts their attention to something else other than the training itself. Our research aims to eliminate this drawback by providing enriched and personalised feedback in realtime. | ||

title:The verification of brushwork of Chinese ink-characters by using the proportion of reflected light and transmissive light.
abstract: In recent years, digital archives of ancient documents have been made. Though they are preserved in a two-dimensional image, I think that it is also important the features such as Strength of brush’s pressure and movement of Japanese brush are preserved. On my research, I think that there are differences of penetration of Chinese ink by Strength of brush’s pressure. By measuring three components of front reflected light, back reflected light, and front transmissive light, I researched what is the relationship between brushwork and them. I will explain about method of the measure, its result, and future tasks. language of the presentation: Japanese 発表題目:反射光・透過光の比率に基つく墨字の筆遣いの検証 発表概要:近年、古文書のテシタルアーカイフか行われている。それらは 2 次元の画像て保存 されているか、筆圧や筆の動きなとの特徴の保存も重要てあると考えられる。本研究ては、 筆圧の強さにより墨の浸透に違いかあると考え、墨字の表面反射、裏面反射、表面透過の 3成分を計測し、それらから筆遣いにとのような関係かあるかを調へた。 その計測方法と結果及ひ今後の課題について説明していく。 | ||

title: Multi-band light transport analysis for estimation of sugar content distribution
abstract: The measurement technology of the sugar content based on the absorbance spectrum is used for selection and promotion of the fruit. However, it measures the total amount of the sugar in fruit, not a spatial distribution. Meanwhile, the scattering optical tomography has been studied, that estimates the internal structure from the scattering of the incoming light. The region of high sugar concentration would change the scattering of a specific band. The aim of this study is to estimate an internal sugar distribution using multi-band scattering tomography. language of the presentation: Japanese 発表題目: 糖度分布推定のための多波長光伝播解析 吸収スペクトル測定による果実の糖度計測は実用化され，選果および販促に利用されている．しかし，現在の糖度計測は果実に含まれる糖分の総量の評価するものであり，糖度の空間分布は計測できない．一方で，光が物体に入射したときの散乱から内部構造を推定する，散乱光トモグラフィが研究されている．糖度が高い領域では，特定の波長の光の吸収特性が異なるため，散乱の様子が変化すると考えられる．本研究では，多波長に対する散乱光トモグラフィにより，物体内部の糖度分布の推定を目指す． | ||
