A computational method for partitioning a charge density grid into Bader volumes is presented which is efficient, robust, and scales linearly with the number of grid points. The partitioning algorithm follows the steepest ascent paths along the charge density gradient from grid point to grid point until a charge density maximum is reached. In this paper, we describe how accurate off-lattice ascent paths can be represented with respect to the grid points. This improvement maintains the efficient linear scaling of an earlier version of the algorithm, and eliminates a tendency for the Bader surfaces to be aligned along the grid directions. As the algorithm assigns grid points to charge density maxima, subsequent paths are terminated when they reach previously assigned grid points. It is this grid-based approach which gives the algorithm its efficiency, and allows for the analysis of the large grids generated from plane-wave-based density functional theory calculations.

Natural aerosols, originating from uncontrollable processes, are widely distributed and often interfere with the remote sensing of anthropogenic aerosols. This interference occurs because distinguishing between particle types is challenging when they coexist. Despite their significant impact on radiative forcing and climate, research on natural aerosols remains limited due to their unpredictable nature. To address this, we implemented a pilot-scale open chamber system coupled with multi-wavelength elastic polarized LiDAR. This system enables the separation of target particles from ambient aerosols, enabling the development of a specialized analysis algorithm that calculates optical parameters-such as the Angstrodm Exponent (AE) and depolarization ratio (delta)- which serve as unique "fingerprints" for distinguishing aerosol types. Our experiments included some natural particles, such as yeast, whey protein, fly ash, flour, pine tree pollen, and kaolinite. Distinct optical properties were observed, with yeast exhibiting high delta values at 532 nm (0.31 +/- 0.09) and 1064 nm (0.06 +/- 0.01). Whey protein and fly ash were distinguishable based on AE values of -0.23 +/- 1.16 and 0.31 +/- 0.59, respectively. Pollen, another key natural aerosol, showed delta values of 0.33 +/- 0.03 at 532 nm and 0.04 +/- 0.01 at 1064 nm, enabling clear differentiation from other aerosol types. By incorporating infrared wavelengths into our LiDAR system, we enhanced the accuracy of aerosol characterization. This study highlights the approach for distinguishing natural aerosols and lays the groundwork for continuous monitoring systems to understand their atmospheric and climatic impacts better.

In this study, Artificial Bee Colony (ABC) algorithm based classifier is used. Also, in order to improve the effectiveness of ABC algorithm, some modifications are done. New method is called MABC algorithm. Both methods are applied on various real life data sets such as IRIS, WINE, PIMA, BUPA, ECG and results are compared. Those datasets are obtained from UCI Machine Learning Repository and MITBIH ECG database. In addition to it, validity indices and effects of some control parameters such as MCN, Limit are examined. It is observed that, selected features have significiant effect on classification success rate of classifier. If there is high overlap between the classes, success rate of classifier decreases. However observed results indicate that ABC algorithm can successfully be used for classification of multi dimensional datasets. By means of SCTR control parameter, MABC algorithm based classifier provides higher classification success rates versus ABC algorithm, independent from Limit and MCN values.

This paper proposes new methods for analyzing image sequences and updating textures of the three-dimensional (3-D) facial model. The paper also describes a method for synthesizing various facial expressions. These three methods are the key technologies for the model-based image coding system. The input image analysis technique directly and robustly estimates the 3-D head motions and the facial expressions without two-dimensional (2-D) any entity correspondences. This technique resolves the 2-D correspondence mismatch errors and provides quality reproduction of the original images by fully incorporating the synthesis rules. To verify analysis algorithm, the paper performs quantitative and subjective evaluations. The paper presents two methods for updating the texture of the facial model to improve the quality of the synthesized images. The first method focuses on the facial parts with large change of the brightness according to the various facial expressions for saving of the transmission bit rates. On the other hand, the second method focuses on all changes of brightness caused by the 3-D head motions as well as the facial expressions. The transmission bit rates are estimated according to the update methods. For synthesizing the output images, the paper describes rules that simulate the facial muscular actions because the muscles cause the facial expressions. These rules more easily synthesize the high-quality facial images that represent the various facial expressions. Now, the 34 rules for the muscular actions have been developed.

A general approach to the kinematic analysis of planar geared linkage mechanisms (GLMs) is presented based on their structural topological characteristics. Firstly, a systematic method for decomposing a GLM into a series of sequential independent kinematic units, such as the simple links and the dyad link groups is proposed. The concept of tricolored graph and its mathematic expressions are introduced to describe the topological relationship between the kinematic pairs and the links in a GLM. The criteria and process for the structural decomposition and for choosing circuits using the theory of type transformation are established. Then the kinematic equations and the analytic solutions for the kinematic units are derived, and the method for the kinematic analysis of position, velocity and acceleration of GLMs is obtained in an algorithmic fashion. Finally, an application program has been developed, by which the whole work from the structural decomposition to the kinematic analysis can be accomplished automatically for any one of the GLMs. Some examples are used to illustrate the procedures.

The identification of spatiotemporally restricted Ca2+ signals, Ca2+ sparks, was instrumental for our understanding of cardiac Ca2+ homeostasis. High-speed 2D confocal imaging enables acquisition of such Ca2+ sparks with high-content information but their full appreciation is constrained by the lack of unbiased and easy-to-use analysis tools. We developed a software toolset for unbiased and automatic Ca2+ spark analysis for huge data sets of subcellular Ca2+ signals. iSpark was developed to be scanner and detector independent. In myocytes from hearts subjected to various degrees of hypertrophy we acquired > 5.000.000 Ca2+ sparks from 14 mice. The iSpark-enabled analysis of this large Ca2+ spark data set showed that the highly organized distribution of Ca2+ sparks present in healthy cells disarrayed concomitant with the development of aberrant transverse tubules and disease severity. Thus, iSpark represents a versatile and universal tool for analyzing local Ca2+ signaling in healthy as well as diseased, aberrant local Ca2+ signal transduction. The results from the unbiased analysis of large data sets provide a deeper insight into possible mechanisms contributing to the onset and progression of cardiac diseases such as hypertrophy.

Current analysis platforms and methods for detecting copy number variation

Copy number variation (CNV), generated through duplication or deletion events that affect one or more loci, is widespread in the human genomes and is often associated with functional consequences that may include changes in gene expression levels or fusion of genes. Genome-wide association studies indicate that some disease phenotypes and physiological pathways might be impacted by CNV in a small number of characterized genomic regions. However, the pervasiveness and full impact of such variation remains unclear. Suitable analytic methods are needed to thoroughly mine human genomes for genomic structural variation, and to explore the interplay between observed CNV and disease phenotypes, but many medical researchers are unfamiliar with the features and nuances of recently developed technologies for detecting CNV. In this article, we evaluate a suite of commonly used and recently developed approaches to uncovering genome-wide CNVs and discuss the relative merits of each.

As software and hardware have grown in functionality and complexity, the existing computer systems are confronting serious challenges with safety, dependability and reliability. Being one of the primary causes with responsibility for these challenges, the software-hardware interaction is advanced and widely studied in recent years. Unfortunately, none of the state-of-art researches has achieved widespread applicability in analyzing software-hardware interaction. Due to a lack of general model to describe the process, we present a software-hardware interaction model based on Petri Net(SHIPN), and also propose the systemic analysis method and process for software-hardware interaction. Indicating as a six-ttiple Petri Net, SHIPN is a logic model of system events, and denote the cause and effect between the software events and hardware events, as well as the process of system events. Especially. SHIPN has non-conflict, non-collision and non-competition of resources, and is essentially different from the traditional Petri Net. Subsequently, we define formalized software-hardware interaction events on the basis of SHIPN, and designed an analysis algorithm based on the incident matrix to deduce causations and propagation paths of each software-hardware interaction. An application case in the communication control system demonstrates that SHIPN is an accurate and practicable model, and the proposed method provides an effective approach to analyze software-hardware interaction.

Not so long ago data warehouses were used to process data sets loaded periodically during ETL process (Extraction, Transformation and Loading). We could distinguish two kinds of ETL processes: full and incremental. Now we often have to process real-time data and analyse them almost on-the-fly, so the analyses are always up to date. There are many possible applications for real-time data warehouses. In most cases two features are important: delivering data to the warehouse as quick as possible, and not losing any tuple in case of failures. In this paper we describe an architecture for gathering and processing data from geographically distributed data sources and we define a method for analysing properties of the connections structure, finding the weakest points in case of single and multiple node failures. At the end of the paper our future plans are described briefly.
