To handle massive binary-coding infeasible solutions in distribution network reconfiguration, a sequence coding is presented A loop is a gene and the switch sequence in the loop is the gene value. To resolve mutation probability and slow later-period convergence in clonal genetic algorithm(CGA), particle clonal genetic algorithm(PCGA) is proposed It builds particle swarm algorithm(PSO) mutation operator;and makes up premature convergence of PSO and blindness of CGA. It ensures evolution direction and range based on historical records and swarm records. Global optimal solution is found with fewer generations and shorter searching time. IEEE69 example shows that the method can save calculation time and promote search efficiency obviously.

This paper describes a new technique for reconstructing an image sequence from spatio-temporally represented contour information. The contour information includes geometry and amplitude information. The dependency of contours between frames is determined by their shape, amplitude and temporal difference. Contours are connected if the dependency of the contours between adjacent frames is strong. Connected contour groups are reconstructed in the form of a tree structure from dominant contours using their motion vector to each frame. Simulation results show that a constructed image sequence can be obtained with about 128 kbit/s for color CIF format image sequences at 25 frames/s.

DIFFERENTIAL-SPIHT FOR IMAGE sequence coding

DIFFERENTIAL-SPIHT FOR IMAGE SEQUENCE CODING

Efficient image sequence coding exploits both spatial correlation and temporal correlation. SPIHT is a powerful algorithm in exploiting spatial correlations for still image coding. Based on SPIHT, we present a novel approach to exploit temporal correlations for image sequence coding, while maintaining single frame, random access decoding. The socalled Differential-SPIHT takes advantage of inter-frame correlations by reusing the significance testing data of a SPIHT coded frame. From simulation results of videos and volumetric medical images, Differential-SPIHT offers significant reductions in bitrate from conventional two-dimensional (2D) SPIHT for the same reconstruction PSNR, while retaining the desirables features of rate scalability and computational simplicity.

Role of action observation and action in sequence learning and coding

A complex sequence learning task was used to determine if the type of coding acquired through physical practice (PP), observation of the stimulus (Obs-S), or observation of stimulus and action (Obs-SA) differs between conditions and whether the type of observation influences subsequent learning of the task when physical practice was permitted. Participants in the Obs-S group were permitted to watch the sequentially illuminated stimuli on the screen. In the Obs-SA group participants could see both flexion-extension movements of the model's arm performing the sequence and the sequentially illuminated stimuli on the screen. Participants in the PP group actually performed the 16-element sequence with their dominant right arm. Delayed retention tests and two inter-manual transfer tests were completed following each of two acquisition sessions. First, the data indicated that learning the sequence structure, as revealed by response time per element, occurred similarly irrespective of the initial practice condition. Secondly, the movement sequence appeared to be coded in abstract visual-spatial coordinates resulting in effector-independent performance. Finally, observing the model's action and sequential stimuli allows participants to transfer the perceived aspects of the movement sequence into efficient coordination patterns when additional physical practice is permitted.

Detecting patterns, and noticing unexpected pattern changes, in the environment is a vital aspect of sensory processing. Adaptation and prediction error responses are two components of neural processing related to these tasks, and previous studies in the auditory system in rodents show that these two components are partially dissociable in terms of the topography and latency of neural responses to sensory deviants. However, many previous studies have focused on repetitions of single stimuli, such as pure tones, which have limited ecological validity. In this study, we tested whether the auditory cortical activity shows adaptation to repetition of more complex sound patterns (disyllabic pairs). Specifically, we compared neural responses to violations of sequences based on single stimulus probability only, against responses to more complex violations based on stimulus order. We employed an auditory oddball paradigm and monitored the auditory cortex (AC) activity of awake mice (N = 8) using wide-field calcium imaging. We found that cortical responses were sensitive both to single stimulus probabilities and to more global stimulus patterns, as mismatch signals were elicited following both substitution deviants and transposition deviants. Notably, higher order AC area elicited larger mismatch signaling to those deviants than primary AC, which suggests a hierarchical gradient of prediction error signaling in the auditory cortex. Such a hierarchical gradient was observed for late but not early peaks of calcium transients to deviants, suggesting that the late part of the deviant response may reflect prediction error signaling in response to more complex sensory pattern violations. Significance statement: Detecting the unexpected change of patterns from the dynamic environment is vital for sensory processing, as it is essential to survival for humans and animals. Using wide-field calcium imaging, we investigated whether the auditory cortex of awake mice exhibits a hierarchic

In order to effectively apply the detailed geographic and load information provided by digital technology, this paper proposes a practical double-Q planning model for large-scale medium voltage distribution network. Meanwhile, a coding method and an elite Ant-Q algorithm(EAQ) suitable for solving the model in this paper are proposed. Based on the basic characteristics of the medium voltage distribution network, the components in the distribution network are abstracted into nodes and branches in the graph theory. A variety of practical issue, such as cost parameters (investments, maintenance, reliability) and technical constraints (feeder capacity constraints, number constraints of substation feeder), as well as road network constraints and connection mode constraints are taken into consideration. In addition, the storage of road network matrix information, reliability evaluation algorithm and model solving algorithm are suitable for large-scale distribution network. Finally, the proposed model and algorithm are applied to a business area to be planned in Guangzhou, which verifies the effectiveness of the proposed model and algorithm.

LOSSLESS COMPRESSION OF WAVE-FORM DATA FOR EFFICIENT STORAGE AND TRANSMISSION

引用

IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING 1993年第3期31卷 645-654页

This paper describes a technique for lossless waveform data compression. The technique consists of two stages. The first stage is a modified form of linear prediction with discrete coefficients and the second stage is bi-level sequence coding. The linear predictor generates an error or residue sequence in a way such that exact reconstruction of the original data sequence can be accomplished with a simple algorithm. The residue sequence is essentially white Gaussian with seismic or other similar waveform data [1]-[3]. Bi-level sequence coding, in which two sample sizes are chosen and the residue sequence is encoded into subsequences that alternate from one level to the other, further compresses the residue sequence. The principal feature of the two-stage data compression algorithm is that it is lossless, that is, it allows exact, bit-for-bit recovery of the original data sequence. The performance of the lossless compression algorithm at each stage is analyzed. The advantages of using bi-level sequence coding in the second stage are its simplicity of implementation, its effectiveness on data with large amplitude variations, and its near-optimal performance in encoding Gaussian sequences. Applications of the two-stage technique to typical seismic data indicates that an average number of compressed bits per sample close to the lower bound is achievable in practical situations.

An efficient and reproducible protocol for Agrobacterium tumefaciens-mediated genetic transformation and plant regeneration of Hevea brasiliensis with the gene coding for superoxide dismutase under the control of Figwort Mosaic Virus (FMV) 34S promoter has been developed. H. brasiliensis (clone RRII 105) callus derived from immature anther was transformed with A. tumefaciens strain EHA 101, harbouring the binary vector containing the sequence coding for neomycin phosphotransferase (nptII) as the selectable marker gene, P-glucuronidase (GUS) as the reporter gene and the sequence coding for Mn-superoxide dismutase (Mn-SOD) under the control of FMV 34S promoter. The kanamycin-resistant GUS positive calli were selected and proliferated in Murashige and Skoog medium fortified with 2,4-D (4.5 muM), BAP (2.2 muM) and NAA (1.1 muM). High-frequency embryo induction was obtained in modified MS medium supplemented with BAP (1.5 muM), Kn (1.4 muM), NAA (1.1 muM) and GA(3) (2.0 muM). Embryo maturation was obtained in modified MS medium containing GA(3) (1.2 muM) and TDZ (1.5 muM). Twenty per cent of the mature transgenic embryos developed into plantlets. These plantlets were planted in polybags after hardening and maintained in a greenhouse. The transformation event was confirmed by PCR amplification with SOD and nptII-specific primers and Southern hybridization with nptII specific probe using DNA isolated from transgenic plants as the template.
