Biofilms are complex aggregates formed by microorganisms such as bacteria, fungi and algae, which grow at the interfaces between water and natural or artificial materials. They are actively involved in processes of sorption and desorption of metal ions in water and reflect the environmental conditions in the recent past. Therefore, biofilms can be used as bioindicators of water quality. The goa...

Data mining classification algorithms are centralized algorithm and works on centralized database. In this information age, organizations uses distributed database. Since data mining of private data is one of the keys to success for an organization, it is a challenging task to implement data mining in distributed database. Collaboration of different organization brings mutual benefits to the pa...

As a greedy search algorithm, classification and regression tree (CART) is easily relapsing into overfitting while modeling microarray gene expression data. A straightforward solution is to filter irrelevant genes via identifying significant ones. Considering some significant genes with multi-modal expression patterns exhibiting systematic difference in within-class samples are difficult to be ...

The big challenge for many areas such as business, marketing, medical science etc. is management of information. The solution for this is provided by the data mining. The application of data mining is text mining, which provides methods such as classification, clustering etc. to extract the important information from unstructured data or text documents. The technique which is used for grouping ...

A personal credit evaluation algorithm is proposed by the design of a decision tree with boosting algorithm, and classification carried out. By comparison conventional it shown that acts to speed up processing time. The Classification Regression Tree (CART) showed 90.95% accuracy, slightly higher than without boosting, 90.31%. To avoid overfitting model on training set due unreasonable data div...

This study presents a Linear Quadratic Optimal (LQR) controller design for an inverted pendulum on a cart using the Artificial Bee Colony (ABC) algorithm. Main design parameters of the linear quadratic regulator are the weighting matrices. Generally, selecting weighting matrices is managed by trial and error since there exists no apparent connection between these weights and time domain require...

BACKGROUND Transmission of drug-resistant HIV-1 (TDR) can impair the virologic response to antiretroviral combination therapy. Aim of the study was to assess the impact of TDR on treatment success of resistance test-guided first-line therapy in the German HIV-1 Seroconverter Cohort for patients infected with HIV between 1996 and 2010. An update of the prevalence of TDR and trend over time was p...

The timely and accurate mapping of the spatial distribution grasslands is crucial for maintaining grassland habitats ensuring sustainable utilization resources. We used Google Earth Engine (GEE) Sentinel-2 data mountain extraction in Yunnan, China. differences normalized vegetation index time-series different ground objects were compared. February to March, during senescence, was optimum phenol...

This paper is concerned with the stability analysis of networked control systems with dynamic quantization, variable sampling intervals and communication delays. A time-triggered zooming algorithm for the dynamic quantization at the sensor side is proposed that leads to an exponentially stable closed-loop system. The algorithm includes proper initialization of the zoomparameter.More precisely, ...

HYPERMASK is a system which projects an animated face onto a physical mask, worn by an actor. As the mask moves within a prescribed area, its position and orientation are detected by a camera, and the projected image changes with respect to the viewpoint of the audience. The lips of the projected face are automatically synthesized in real time with the voice of the actor, who also controls the ...
