(要約) 本論文は，粒子間の近傍距離を考慮するネットワーク構造型PSO(NS-PSO)を提案している．NS-PSOの全ての粒子は，トポロジー空間の近傍関係に従って，他の粒子と結合されている．また，NS-PSOはその結合関係を，粒子間の情報交換だけでなく，群の多様性にも用いる．粒子間のトポロジー空間内の近傍距離を粒子の更新に用いることで，群の多様性が向上するだけでなく，解が局所解に陥ることを避ける効果がある．通常のPSOと比較したシミュレーション結果から，提案手法であるNS-PSOは探索性能が向上していることを確認した．

(要約) 本論文ではノンコヒーレントカオス通信システムのための，カオスダイナミクスの分離と再構成に基づく多値変調手法を提案する．多値変調方式とはbビットのデータをM(=2^b)個の独立した系列を用いて送信する手法である．M個の系列を生成するために，本研究ではM個のインターリーバとデインターリーバのペアを用意し，カオス系列の分離と再構成を行う．具体的には，送受信機間で複数のインターリーバとデインターリーバペアにbビットのデータを対応させる．送信機側では，送信データに対応したパターンを選び，それに従ってカオス系列の並び替え(分離)を行うことでデータの変調を行う．受信機側では，共有しているパターンに従って受信した信号の系列を元に戻す(再構成)．ここで，送信側で並べ替えられた系列を元に戻すデインターリーバは1種類しかないことに注意する．ゆえに，再構成された系列のカオスダイナミクスを解析し，元のカオス系列に戻すデインターリーバを選択する事で，そのデインターリーバに対応しているデータを復調データと判定できる．以上の提案した多値変調方式を本論文ではコンピュータシミュレーションにより評価する． (キーワード) カオス (chaos) / noncoherent chaos-based communications / M-ary modulation / deterministic chaotic dynamics (出版サイトへのリンク) ● Publication site (DOI): 10.1587/nolta.5.210 (文献検索サイトへのリンク) ● CiNii @ 国立情報学研究所 (CRID): 1390001205346343168 ● Search Scopus @ Elsevier (DOI): 10.1587/nolta.5.210 (DOI: 10.1587/nolta.5.210, CiNii: 1390001205346343168)

(要約) 本論文ではノンコヒーレントカオス通信システムでの利用を想定したカオスダイナミクスに基づく誤り訂正手法を提案する．今，同一のカオス写像から生成された2つの連続するカオス系列を考える．この時，2つ目のカオス系列の初期値は1つ目のカオス系列の最後の値に基づいて生成された値と仮定すると，この2つの系列は同一のカオスダイナミクスを持つ系列として見なす事ができる．この特徴は受信機側で正確にデータ復調するための付加情報として利用できると考え，これを本論文では誤り訂正に利用する．提案手法を用いてコンピュータシミュレーションを行った結果，誤り訂正無しの従来手法と比較して，提案手法では約1∼1.5dBの利得が得られた． (キーワード) カオス (chaos) / noncoherent chaos communications / error-correcting scheme / chaotic dynamics (出版サイトへのリンク) ● Publication site (DOI): 10.1587/nolta.1.196 (文献検索サイトへのリンク) ● CiNii @ 国立情報学研究所 (CRID): 1390282680322074496 ● Search Scopus @ Elsevier (DOI): 10.1587/nolta.1.196 (DOI: 10.1587/nolta.1.196, CiNii: 1390282680322074496)

(要約) 本論文ではノンコヒーレントカオス通信システムにおける，HaslerとSchiming らによって提案された最適受信機に注目する．この最適受信機は送信機側で用いられているカオス写像と受信信号系列との確率密度関数(PDF)を算出し，送信側で用いられたカオス写像を確率的に求める事でデータの復調を行う手法である．しかしながら，本手法はPDFの算出に高い計算処理能力が必要である事が知られている．ゆえに，最適受信機と異なるアルゴリズムを用いて，それと同等もしくは近い性能を有する準最適受信機の開発が重要であるとされている．そこで本論文では，PDFの計算を用いない新たな準最適受信機の提案を行う．具体的には，PDFの計算の代わりにカオス写像と受信信号系列との最短距離を計算する事で，距離が短い方のカオス写像を選択する事でデータの復調を行う．最短距離の計算というシンプルな手法を用いた事で，PDFよりも大幅に計算処理時間の短縮に成功した．また，復調性能も最適受信機と同等の性能を示した．

(要約) ミキサ，変調器など通信分野における回路の多くは複数個の独立した周波数成分を持った信号源で駆動されている．もしこれらの信号源の周波数が極端に離れている場合，通常の数値積分手法では時間ステップを高い周波数成分のほうに設定しなければならず解析には大変多くの計算時間を要することとなる．ここではこれらの回路を効率よく解析するための周波数領域での緩和法と多次元フーリエ変換を用いた効率的なアルゴリズムを提案する．まずキャパシタやインダクタなどのリアクタンス成分は過渡現象の減衰成分とは無関係なので，回路を非線形抵抗部分回路とリアクタンス部分とに代用電源を用いて分割してから，それぞれの部分について定常応答が同じとなるように代用電源の値を求めていくものである．これらの手法はSPICEのDC,AC,過渡解析により実行されるため非常にシンプルで効率的なシミュレータとなっている．

(要約) 伝送線路回路網の離散フーリエ変換に基づく方法では，考慮すべき周波数成分の数は回路網の有効周波数と入力電源が制限される時間に依存する．したがって，解析される回路網の有効周波数が同じ場合でも入力電源が長時間にわたる場合には，多くの周波数成分を必要とし演算効率が悪くなるという欠点をもつ．これは，各周波数での応答を求めるために回路方程式をそのたびごとに求解しなければならないことが原因である．本論文では，回路方程式の求解を最小限にとどめ，代わりに周波数応答を近似する方法を提案している．近似法としては，3次スプライン関数による方法と離散フーリエ変換·逆変換による方法を用いており，数値計算例を通して，比較的小規模な問題に対しては高速シミュレーション手法として知られているモーメント·マッチング法と比較して演算効率が優れていることが示されている．

(要約) VLSI 内部の配線は，不均一(位置によって異なった)特性を有している．その一方で，高速デバイスでは，非線形性線路の解析が必要となる．本論文では，不均一·非線形伝送線路の解析に周波数領域における方法を提案した．伝送線路の回路方程式である偏微分方程式を周波数領域へ変換し，応答をフーリエ級数で仮定する．この結果得られる常微分方程式を数値積分法によって求解し，回路の応答を得るというものである．本手法は，如何なる不均一特性へも適用可能であり，複雑な形状をもつVLSI 回路の解析に有効となる．

Masato Tomita, Haruna Matsushita and Yoshifumi Nishio : Data Extraction by Self-Organizing Map Containing Neurons with Additional States, Journal of Signal Processing, Vol.10, No.4, 243-246, 2006. (要約) A self-organizing map (SOM) is an unsupervised neural network introduced by Teuvo Kohonen. SOMs have attracted attention in studies of clustering in recent years. In this study, we propose SOM containing neurons with additional states. The basic algorithm of the proposed SOM is the same as that of the conventional SOM. However each neuron of the proposed SOM has an additional state value. The value decreases according to the update of the weight vectors. Furthermore, as the value decreases, the updated rate of the neurons is reduced. The behavior of the proposed SOM is investigated with an application to clustering input data including a lot of noise. We can see that the proposed SOM successfully extracts the cluster.

(要約) 本論文では，同じ周波数を持つN個のウィーンブリッジ発振器を1つの抵抗で結合したシステムを提案し，そこに見られる同期現象を調べている．本システムは，我々が過去に報告したLC発振器によるシステムとは異なる構造を持っているため，N相同期現象ではなく，3相または同相同期現象が見られる．本システムにおいても，初期状態を変化させることで，非常に多くの異なる安定な位相状態を得ることができる．特に，Nがそれほど大きくない場合，LC発振器によるシステムよりも多くの位相状態を得ることができる．本システムはインダクタを含んでおらず，また，外乱にも強いと考えられるため，LC発振器によるシステムと比べVLSIへの実装により適していると考えられる．

(要約) 可視光画像と赤外線画像の合成は,それぞれの画像が持った特徴から非常に重要な情報を得ることができる.現在まで,様々な画像合成法が提案されている.特に,パルス結合ニューラルネットワークは画像のエッジに対して強く反応することから,その有用性が指摘されている.本研究では,非サブサンプルドカンターレット変換を用いて2種類の画像を係数に分解し,各係数ごとに合成を行う.分解された画像係数は,ラプラシアンフィルタと平均化フィルタの二種類のフィルタにかけららた後,パルス結合ニューラルネットワークによって合成される.提案する画像合成法を用いることによって,パルス結合ニューラルネットワークのみで画像合成を行った場合より優れた画像が得られることを示す.

(要約) 本論文では，カオス発振回路の設計法について論じている．本手法は，異なる周波数特性をもつ二つの発振器をダイオードで結合するという極めてシンプルな手法であり，また，発振器のタイプを変化させることにより様々なカオス発生回路が設計できることを示している．
