ディジタル画像上の拡張α-hullとその応用

α-hullは凸包の拡張概念で，パラメータαの調整によって点集合を抱合する領域を種々の精度で構成できるが，ディジタル画像に対しては適用された例がない．本論文では，まず連続平面の孤立点集合に対して定義し，その性質を調べる．次に，EDα―hullは，与えられた入力2値画像にR＝|1/α|回の拡張(dilation)に続く，R回の縮小(erosion)を施したものに等しい．あるいは，入力画像の背景の距離変換で距離地R以上の部分を抽出する処理を2回行うことでもEDα-hullを求めることができる．最後に，生体組織標本顕微鏡像の解析に対する応用例を示し，また，計算量について簡単に検討する．上記アルゴリズムでは，入力画像を6回走査することでEDα-hullを得ることができ，計算量は画像の内容にほとんど関係しない．journal articl

Prediction of 24-h and 6-h Periods before Calving Using a Multimodal Tail-Attached Device Equipped with a Thermistor and 3-Axis Accelerometer through Supervised Machine Learning

In this study, we developed calving prediction models for 24-h and 6-h periods before calving using data on physiological (tail skin temperature) and behavioral (activity intensity, lying time, posture change, and tail raising) parameters obtained using a multimodal tail-attached device (tail sensor). The efficiencies of the models were validated under tethering (tie-stall) and untethering (free-stall and individual pen) conditions. Data were collected from 33 and 30 pregnant cattle under tethering and untethering conditions, respectively, from approximately 15 days before the expected calving date. Based on pre-calving changes, 40 features (8 physiological and 32 behavioral) were extracted from the sensor data, and one non-sensor-based feature (days to the expected calving date) was added to develop models using a support vector machine. Cross-validation showed that calving within the next 24 h under tethering and untethering conditions was predicted with a sensitivity of 97% and 93% and precision of 80% and 76%, respectively, while calving within the next 6 h was predicted with a sensitivity of 91% and 90% and precision of 88% and 90%, respectively. Calving prediction models based on the tail sensor data with supervised machine learning have the potential to achieve effective calving prediction, irrespective of the cattle housing conditions

GenoBase: comprehensive resource database of Escherichia coli K-12

Comprehensive experimental resources, such as ORFeome clone libraries and deletion mutant collections, are fundamental tools for elucidation of gene function. Data sets by omics analysis using these resources provide key information for functional analysis, modeling and simulation both in individual and systematic approaches. With the long-term goal of complete understanding of a cell, we have over the past decade created a variety of clone and mutant sets for functional genomics studies of Escherichia coli K-12. We have made these experimental resources freely available to the academic community worldwide. Accordingly, these resources have now been used in numerous investigations of a multitude of cell processes. Quality control is extremely important for evaluating results generated by these resources. Because the annotation has been changed since 2005, which we originally used for the construction, we have updated these genomic resources accordingly. Here, we describe GenoBase (http://ecoli.naist.jp/GB/), which contains key information about comprehensive experimental resources of E. coli K-12, their quality control and several omics data sets generated using these resources.journal articl

Fundamental verification of a method to achieve compatibility between comfort and energy saving by using wall lighting in the intelligent lighting system

我々は，オフィスにおける天井照明を個別に調光することで，各執務者に個別の照度環境を実現する知的照明システムの研究を行っている．知的照明システムにおいて，執務者の目標照度を満たすうえで必要がない天井照明に関しては，省エネルギーの観点から消灯する．しかし，その場合，執務者の周辺の空間が暗くなり，部屋の明るさ感が低下するため快適性が損なわれる．これを改善する方法として，消灯した照明を一定の低い光度で点灯する手法（以後，低光度点灯手法）が考えられる．低光度点灯手法を用いることで，部屋の明るさ感が向上するが，消費電力の増大に繋がる．部屋の明るさ感を向上させる別の方法として壁面照明がある．そこで本研究では，知的照明システムにおいて，不要な照明を消灯した場合に壁面照明を用いて部屋の明るさ感を保つ手法（以後，壁面照明手法）と低光度点灯手法を比較する．快適性を損なわず消費電力を抑える手法が，壁面照明手法と低光度点灯手法のいずれであるか検討する．We are working on an Intelligent Lighting System that individually controls the ceiling lights in an office to create a specific illumination environment for each office worker. The Intelligent Lightning System choose the best pattern to save energy by turning off some ceiling lights if it's possible. However, in that case, the worker is uncomfortable because the space around the office worker gets darker and the room's brightness is reduced. To solve this problem, we consider a method that turns on unnecessary lights at constant low level of luminosity (named low luminosity lighting method). Using the low luminosity lighting method improves the brightness of the room, but the power consumption increases. Another way to improve the brightness of the room is wall lighting. In this research, we compare the method of maintaining the brightness of the room using the wall lighting in the Intelligent Lighting System when unnecessary lighting is turned off (named wall lighting method) and the low luminosity lighting method.application/pdfdepartmental bulletin pape
