This paper describes highly parallel analog image coding and decoding by cellular neural networks (CNNs). The communication system in which the coder (C-) and decoder (D-) CNNs are embedded consists of a differential transmitter with an internal receiver model in the feedback loop. The C-CNN encodes the image through two cascaded techniques: structural compression and halftoning. The D-CNN decodes the received data through a reconstruction process, which includes a dynamic current distribution, so that the original input to the C-CNN can be recognized. The halftoning serves as a dynamic quantization to convert each pixel to a binary value depending on the neighboring values. We approach halftoning by the minimization of error energy between the original gray image and reconstructed halftone image, and the structural compression from the viewpoints of topological and regularization theories. All dynamics are described by CNN state equations. Both the proposed coding and decoding algorithms use only local image information in a space invariant manner, therefore errors are distributed evenly and will not introduce the blocking effects found in DCT-based coding methods. In the future, the use of parallel inputs from on-chip photodetectors would allow direct dynamic quantization and compression of image sequences without the use of multiple bit analog-to-digital converters. To validate our theory, a simulation has been performed by using the relaxation method on an 150 frame image sequence. Each input image was 256× pixels with 8 bits per pixel. The simulated fixed compression rate, not including the Huffman coding, was about 1/16 with a PSNR of 31[dB]〜35[dB].

Un partito cattolico nacque nell'autunno 1942, dalla confluenza tra l'antico Partito Popolare Italiano e il Movimento Guelfo, che faceva capo a Piero Malvestiti. Per il nuovo partito si scelse il nome di Democrazia Cristiana. Il nome riconosce i meriti dei neo-Guelfi, ma il sorgere del partito cristiano in forma nuova e con nome mutato permette a Alcide De Gasperi, il leader ex-Partito Popolare un certo spazio di liberta rispetto alla tradizione del partito di Sturzo. In questa fase la DC non puo nascere soltanto dai quadri della Resistenza, ma in gran parte e costituita dai giovani formati dal Fascismo prima, e poi diventati anti-fascisti o per lo meno afascisti. La DC partecipa alla Resistenza e al CLN. Le vicende successive all'armistizio (8 settembre 1943 - 25 aprile 1945) incidono fortemente sulla struttura del Partito : il centro del Partito deve omogenizzare gli eterogenei meccanismi organizzativi predisposti alla tendenza del Sud per la necessita di intensificare la posizione degasperiana che garantisce la stabilizzazione del Sistema. Il 30 luglio 1943, De Gasperi istituisce la Commissione Direttiva Centrale provvisoria, il primo organo direttivo centrale, di cui e presidente. Poi, nella seduta della Commissione svoltasi il 21 giugno 1944, viene fondata la Giunta Esecutiva Centrale. Nella circolare (29 giugno '44) e prevista la costituzione di Sezioni comunali e le strutture organizzative di base. Il Congresso Interregionale della DC (Congresso di Napoli dell'Italia libera) si svolge nei giorni 29 e 30, con la partecipazione dei delegati provinciali di tutte le regioni liberate e di alcuni rappresentanti di provincie ancora occupate dai tedeschi. Nel Congresso viene consolidata la struttura organizzativa del Partito mediante la costituzione degli organi centrali formali (Congresso, Consiglio Nazionale, Direzione Centrale, Segreteria Politica).

[Purpose] This study examined the exercise intensity and psychophysiological responses to a self-selected resistance training session in sedentary male subjects. [Subjects and Methods] Twelve sedentary male subjects (35.8 ± 5.8 years; 25.5 ± 2.6 kg·m2) underwent four sessions at 48-h intervals: familiarization; two sessions of one repetition maximum test and a resistance training session in which they were told to self-select a load to complete 3 sets of 10 repetitions of chest press, leg press, seated rows, knee extension, overhead press, biceps curl, and triceps pushdown exercises. During the latter, the percentage of one repetition maximum, affective responses (feeling scale), and rating of perceived exertion (OMNI-RES scale) were measured. [Results] The percentage of one repetition maximum for all exercises was >51% (14–31% variability), the rating of perceived exertion was 5–6 (7–11% variability), and the affective responses was 0–1 point with large variability. [Conclusion] Sedentary male subjects self-selected approximately 55% of one maximum repetition, which was above the intensity suggested to increase strength in sedentary individuals, but below the recommended intensity to improve strength in novice to intermediate exercisers. The rating of perceived exertion was indicative of moderate intensity and slightly positive affective responses.

To understand the basic mechanism governing the size evolution of tropical cyclones (TCs), we systematically perform numerical experiments using the primitive equation system on an f-plane. A simplified, TC-like vortex is initially given and an external forcing mimicking cumulus heating is applied to an annular region at a prescribed distance from the vortex center. Moist process and surface friction are excluded for simplification. We focus on the sensitivity of size evolution to the location of the forcing. The vortex size is defined as the radius of 15 m s-1 lowest-level wind speed (R15). The evolution of R15 depends on the forcing location, and its dependence can be understood by considering radial transport of the absolute angular momentum (AAM) at R15 due to the heat-induced secondary circulation (SC), whose structure is governed by the distribution of inertial stability. When the forcing is applied to the outer part of a vortex but still inside R15, where inertial stability is weak, the SC extends to the outside of R15 and carries AAM inward. Thus, R15 increases. Conversely, when the forcing is applied near the center of the vortex, where inertial stability is strong, the SC closes inside R15 and R15 hardly increases. These results indicate that extension of the heat-induced SC to the outside of R15 is important for the evolution of the vortex size. Moreover, the further beyond R15 the SC extends, the more the vortex size increases. This relationship is consistent with the result of the parcel trajectory analysis; the larger the extent of SC, the longer distances the parcels cover, conserving larger AAM. Finally, when the forcing is applied to the outside of R15, smaller AAM is carried outward by the SC on the inward side of the heating location, resulting in the decrease of R15.

食品から排出される廃棄物は, 生産・流通の段階のみならず消費段階における家庭から発生する廃棄物が, 食品廃棄物総排出量の半分以上を占めている。このような状況のなか, 食品リサイクル法が施行され食品廃棄物の発生を抑制し, 資源として有効に活用する循環型社会の形成が求められている。そこで, 食品製造業から発生する食品産業廃棄物と家庭から発生する家庭系食品廃棄物の実態を明らかとするために調査を実施した。食品産業廃棄物中の汚泥排出量は, わが国の汚泥排出総量の3.1%を占め, 動植物性残さは動植物性排出総量の78.2%に達していることが明らかとなった。また, 家庭系食品廃棄物の内, 調理くずと食べずに捨てられるものが廃棄物の発生重量の70%を占めていた。家庭系食品廃棄物の家庭内でのリサイクルには困難さが多く, 発生抑制や分別の徹底が資源として活用する上で重要である。

この論文では,熱力学・流体力学に基づいて氷解現象のアニメーションを生成する手法を提案する.提案手法は,熱伝導・対流熱伝達・熱輻射を考慮し,融解後の液体の挙動も計算する.対流熱伝達を考慮する場合,融解する氷(固体)と融解後の水(液体)だけでなく,周囲の空気(気体)の振舞いも考慮しなくてはならず,この気液固三相を流体力学で計算することは非常に難しい問題である.我々は,VOF(Volume-of-Fluid)と呼ばれる単純なカラー関数を液体自由曲面追跡に用い,RCIP(Rational-Constrained Interpolation Profile)法と改良した界面数値拡散の制御手法(STAA 法)を用いることで,レンダリング時に現れる液体表面のエイリアスの問題を解決する.また,気液固の三相を同じ計算空間内でシミュレーションし,各相間の質量の変化量を明示的に扱える簡潔で分かりやすい相変化シミュレーション法を提案する.さらに,熱輻射現象は,フォトンマッピング法を用いて効率的に計算し,レーザによる融解現象などもアニメーション化する.This paper proposes a fast and efficient method for producing physically-based animations of the ice melting phenomenon, including thermal radiation as well as thermal diffusion and convective thermal transfer. Our method adopts a simple color function called VOF (Volumeof-Fluid) with advection to track the free surface, which enables straightforward simulation of the phase changes, such as ice melting. Although advection of functions that vary abruptly, such as the step function, causes numerical problems, we have solved these by the RCIP (Rational-Constrained Interpolation Profile) method. We present an improvement to control numerical diffusion and to render anti-aliased surfaces. The method also employs a technique analogous to photon mapping for calculating thermal radiation. By the photon mapping method tuned for heat calculation, the thermal radiation phenomenon in a scene is solved efficiently by storing thermal energy in each photon. Here, we report the results of several ice melting simulations produced by our method.
