In a voice synthesis apparatus, by bounding a desired range of input text to be output by, e.g., a start tag “<morphing type=“emotion” start=“happy” end=“angry”>” and end tag < / morphing>, a feature of synthetic voice is continuously changed while gradually changing voice from a happy voice to an angry voice upon outputting synthetic voice.

Five circuit synthesis methods, for forming new power conversion circuits with enhanced electromagnetic compatibility and improved AC performance from old circuits with AC performance and / or electromagnetic compatibility deficiencies, are revealed. The new synthesis methods achieve performance improvements without requiring the addition of magnetic cores. In all cases a simple toroidal magnetic core structure is not precluded. In all cases splitting or adding magnetic windings is required, and, in many cases, additional capacitors are required. Many new circuits formed by applying the synthesis methods are revealed. The results achieved by application of the synthesis methods include zero ripple current at all terminals without adding magnetic cores or requiring a complex magnetic circuit element, cancellation of common mode currents, improved control loop bandwidth, and faster transient response.

The invention discloses a power system load modelling method, including the steps that: A, load classification based on daily active load curve; B, load modelling based on statistic synthesis method; C, load model parameter sensitivity analysis and range analysis based on simulation analysis; D, load model parameter node identification based on genetic algorithm, namely node identification is carried out by taking fitted local disturbance data as target, setting low sensitivity parameter value as statistic synthesis method surveying parameter value and adopting the genetic algorithm, so as to obtain multiple groups of load model parameters; E, load model parameter wide area check based on WAMS, namely load model parameter check is carried out by taking the multiple groups of solutions identified by node as initial value and taking accurate fitting on system wide area dynamic characteristic as target, so as to obtain unique solution capable of reflecting wide area dynamic characteristic when system is subject to disturbance. The invention solves the problems of multiple solutions and identifiability of overall measuring identifying method by load point classification and load model parameter aggregation and has popularization and application values.

Method of synthesis for a material made of particles having a core and a coating and / or being connected to each other by carbon cross-linking, the core of these particles containing at least one compound of formula LixM1-yM'y(XO4)n, in which x,y and n are numbers such as 0<=x<=2, 0<=y<=0.6 and 1<=n<=1.5, M is a transition metal, M' is an element with fixed valency, and the synthesis is carried out by reaction and bringing into equilibrium the mixture of precursors, with a reducing gaseous atmosphere, in such a way as to bring the transition metal or metals to the desired valency level, the synthesis being carried out in the presence of a source of carbon called carbon conductor, which is subjected to pyrolysis. The materials obtained have excellent electrical conductivity as well as very improved chemical activity.

Methods, devices, and computer programs are presented for consolidating overlapping data provided by multiple sources. One method includes operations for associating a plurality of devices to a user, each device operable to capture data associated with the user, and for receiving, from the plurality of devices, captured data about a first activity associated with a first period of time. Additionally, the method includes operations for detecting that the received captured data from two or more devices provide overlapping information about the first activity, and for evaluating one or more rules for consolidating the overlapping information to produce consolidated data. The consolidated data provides a unified view of the first activity during the first period of time. The consolidated data is stored in permanent storage and made available for presentation to the user.

Methods and kits are provided for performing multiple rounds of sense RNA synthesis. The sense RNA molecules can be used in various research and diagnostic applications, such as gene expression studies involving nucleic acid microarrays.

The present invention provides substantially monodisperse colloidal nanocrystals and new preparative methods for the synthesis of substantially monodisperse colloidal nanocrystals. These synthetic methods afford the ability to tune nanocrystal size and size distribution. By using non-coordinating solvents in the synthetic process, these procedures constitute easier, less expensive, safer, and more environmentally “green” methods than those currently in use. This invention is generally applicable to any II–VI or III–V semiconductor material, and may be useful in generating metal-nonmetal compounds involving transition metals as well.

The invention provides a Chinese speech synthesis method based on phonemes and rhythm structures. The method is divided into a training stage and a synthesis stage, and comprises the steps of extracting therhythm structure features from the rhythm labeling information in a to-be-processed text according to the linguistic knowledge, and training a rhythm model based on the rhythm structure features; preprocessing the to-be-processed text and an audio to obtain a pinyin sequence containing the rhythm information and the corresponding acoustic features, then training an acoustic model, and deploying the trained rhythm model and acoustic model to a background; obtaining a text containing the rhythm information corresponding to the input text according to the rhythm model; converting into a pinyin sequence with rhythm information, and inputting into the acoustic model to obtain a linear frequency spectrum; and converting the linear frequency spectrum into the audio. According to the Chinesespeech synthesis method, the synthesized voice can be more natural, and especially for the longer clauses, the pause position can be determined. In addition, the model is deployed to the background at the synthesis stage, and the model loading time is saved, so that the voice synthesis speed can be increased.
