Pełny tekst źródłaWe propose a flexible framework to incorporate several different sources of such evidence into a gene finder based on a hidden Markov model. Various sources of evidence are expressed as partial probabilistic statements about the annotation of positions in the sequence, and these are combined with the hidden Markov model to obtain the final gene prediction. The opportunity to use partial statements allows us to handle missing information transparently and to cope with the heterogeneous character of individual sources of evidence. On the other hand, this feature makes the combination step more difficult. We present a new method for combining partial probabilistic statements and prove that it is an extension of existing methods for combining complete probability statements. We evaluate the performance of our system and its individual components on data from the human and fruit fly genomes.
The use of sequence evolutionary conservation as a source of evidence in gene finding requires efficient and sensitive tools for finding similar regions in very long sequences. We present a method for improving the sensitivity of existing tools for this task by careful modeling of sequence properties. In particular, we build a hidden Markov model representing a typical homology between two protein coding regions and then use this model to optimize a component of a heuristic algorithm called a spaced seed. The seeds that we discover significantly improve the accuracy and running time of similarity search in protein coding regions, and are directly applicable to our gene finder.

This present dissertation, structured in the methodology of well-known research as Didactic Engineering, it presents the development of an unpublished class for the teacher on combination analysis in the High School. The objective of this work is to elaborate a didactic material that aids the students in the learning of some concepts of combination analysis in a significant way. The elaborated didactic sequence is inserted in the telephony context and it approaches the current subject on the increment of the 9th digit in the numbers of cellular of the area of the State of São Paulo with code of area 11. The whole sequence was thought so that the student will be the protagonist of its learning, making observations, you conjecture, debating with the colleagues, manipulating materials and solving the problems proposed in the leaves of activities in an autonomous way. The didactic sequence was applied for two groups of 2nd year of the High School in the School Educational Center SESI Bragança Paulista. For they accomplish the activities, the students were divided in groups. All the sheets of activities accomplished by the students and the registrations of observations facts by the teacher during the application of the activities were good as tools to verify the objective plans were reached.

Pełny tekst źródłaThis dissertation presents a semantic-pragmatic study of dialogic uses of mais, oui, non and their four combinations : mais oui, mais non, oui mais et non mais. The dialogic sequences “X – Mais Y” raise the question of the uniqueness of the oppositive connector, because the relationship between the utterances X and Y is very different from that which is established between both utterances in the “X mais Y” monologic configurations. In this dissertation, the two types of linking with mais are analyzed in the framework of dynamic semantics, which aims to describe the meaning of linguistic expressions from their ability to change the context. The enunciative operation of mais is specified from the constraints on the surrounding linguistic context that the examination of various contextual uses of mais in monologue and dialogue revealed. This examination leads to the conclusion that the specificity of dialogic sequences with mais is not related to the semantics of the connector, but the progress of speech, which is different in monologue and dialogue. Combinations of mais with oui and non are considered after a previous detailed analysis of validation marker and rejection marker. The way these two markers interact with the left context reflects their semantic asymmetry, confirmed by the possibility of using them as competing forms to confirm a negative utterance. In combination of oui and non with mais, the second element determines the type of relationship: oui mais and non mais mark the opposition, while mais oui and mais non reflect validation and rejection. However, the first element has a clear implication on the interpretation of the second one. In that sense mais oui and mais non responses present the validated or rejected information as already accepted in the context or, on the contrary, excluded, and therefore impossible to consider. On the other hand, in reactions with oui mais and non mais the oppositive connector regards the information accessible next to the use of the first marker

In this dissertation, We propose to reduce PAPR in OFDM systems and reduce the computational complexity in conventional Partial Transmission Sequence (C-PTS) techniques. First, we presents a modified PTS algorithm for PAPR reduction of M-QAM OFDM signals by partitioning an OFDM block into non-disjoint OFDM sub-blocks. Since an M-QAM constellation can be written as sum of several QPSK constellations, we can then apply different disjoint partitions on the QPSK OFDM blocks, which result in an equivalent non-disjoint partition on the M-QAM OFDM block. Compared to a disjoint sub-block partition in conventional PTS, simulation results show that the modified PTS with a non-disjoint partition achieves better PAPR reduction in adjacent, interleaved, and random partitioning schemes. Second, we propose the parallel PTS (P-PTS) and serial PTS (S-PTS) methods to reduce the C-PTS complexity, based on the fact that the weighting factors are chosen as codewords of a linear block code. Compared to the C-PTS, the P-PTS and S-PTS methods not only reduce the computational complexity but also provide error correction capability for the weighting factors. Third, we present the PAPR reduction of OFDM signals by executing PTS in tree structure and minimal trellis of block codes. The proposed method uses a linear code with the tree structure and good minimal trellis to select the transmitted OFDM signal with minimum PAPR and to transmit side information with error correction. The goals of combining strategy of tree structure and trellis in PTS are twofold: to provide a low complexity PTS for weighting vector search and to highlight error protection capability for side information. Simulation results show that the proposed scheme achieves good PAPR reduction with lower complexity, compared to other PTS approaches.

In this thesis, we propose combination of Convolutional Code(CC) with orthogonal frequency division multiplexing (OFDM) system. This method provides the error correction capability for the input data and the phase factor. One of the drawbacksinOFDM system is the high peak- to-average powerratio (PAPR).when the same sub- carrier phases are adding together.Itcauses the high PAPR in OFDM system. We select PartialTransmitSequence(PTS) systemas the main system to reducethe PAPR, and then use thetree structure to control phase factor number to reduce the comput -ational complexity. Finally, this method does not need to transmit additional sideinformation to the receiver.

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier system capable of high-rate data transmission, and has many advantages. One of the important shortcomings is the Peak To Average Power (PAPR). In order to solve this problem, we have many methods such as SLM, PTS, etc. This article is mainly based on PTS. Compared with the traditional partial transmission sequence (PTS), this paper uses tree and trellis structure of error correction (ECC), it can reduce the peak-to-average power ratio and search complexity either, and based on this, it is applied to data of larger length.

An epicyclic-type automatic transmission is a device which is connected from engine to driving wheels, and the main purpose is to maintain the revolution speed of engine to be in a desired working range while accelerating or decelerating the automobile. The epicyclic -type automatic transmissions in production are mostly Ravigneaux-type epicyclic mechanisms, and in recent year, the development of automatic transmissions for automobile is oriented to the orientation of setting an single epicyclic gear mechanism instead of the input to bring various inputs of revolution speed to increase the total number of speed ratios of an automatic transmission, and such type of epicyclic is called combinational epicyclic-type automatic transmissions for automobiles. For the incompletion in the relative design methodology, a systematic methodology of designing mechanism and clutching-sequence of combinational epicyclic-type automobile transmission is described. First, fundamental principle of the combination and operations of automatic transmissions are analyzed to establish the design requirements. Second, a procedure of structure synthesis of combinational epicyclic-type automobile transmission is brought up which the planar graphic method is applied for. Third, based on Speed Ratio Relationship of each clutching sequence, a procedure of gearing-sequence is introduced. Finally, on the basis of the analytic method, the teeth of gears is to be clarified. The result of this work obtains five types of the combinational epicyclic-type automatic transmissions which could reach six speeds.

In this paper, we proposed three methods of orthogonal frequency division multiplexing (OFDM) system combined partial transmit sequence (PTS) with low complexity. In the PTS, as sub-blocks increase, the performance of reducing peak-to-average power ratio (PAPR) is getting better, but complexity grow exponentially. The first method is to reduce the complexity of PTS by iteration, and uses the information obtained from last time to get better performance, so it can use less sub-blocks to get the same performance as PTS .The second method is to reduce much complexity by modified tree structure than RC-PTS. The last is to reduce complexity of tree structure by Fano algorithm, and changes the parallel form of tree structure into series form. In this method, we also add the threshold to let complexity lower.

Pełny tekst źródłaCytochrome P450 (CYP) is one of the most important drug-metabolizing enzyme families, which participates in the biotransformation of many endogenous and exogenous compounds. Quantitative analysis of CYP expression levels is important when studying the efficacy of new drug molecules and assessing drug-drug interactions in drug development. At present, chemical probe-based assay is the most widely used approach for the evaluation of CYP activity although there are cross-reactions between the isoforms with high sequence homologies. Therefore, quantification of each isozyme is highly desired in regard to meeting the ever-increasing requirements for carrying out pharmacokinetics and personalized medicine in the academic, pharmaceutical, and clinical setting. Herein, an absolute quantification method was employed for the analysis of the seven isoforms CYP1A2, 2B6, 3A4, 3A5, 2C9, 2C19, and 2E1 using a proteome-derived approach in combination with stable isotope dilution assay. The average absolute amount measured from twelve human liver microsomes samples were 39.3, 4.3, 54.0, 4.6, 10.3, 3.0, and 9.3 (pmol/mg protein) for 1A2, 2B6, 3A4, 3A5, 2C9, 2C19, and 2E1, respectively. Importantly, the expression level of CYP3A4 showed high correlation (r = 0.943, p < 0.0001) with the functional activity, which was measured using bufalin-a highly selective chemical probe we have developed. The combination of MRM identification and analysis of the functional activity, as in the case of CYP3A4, provides a protocol which can be extended to other functional enzyme studies with wide application in pharmaceutical research.
