With the increasing demand of power industry for load forecasting, improving accuracy forecasting has become increasingly important. In this paper, we propose an ultra short-term method based on similar day clustering and EEMD (Ensemble Empirical Mode Decomposition). detail, K-means algorithm was utilized to divide historical data into different clusters. Through EEMD, each cluster were decompo...

overcoming spatial and temporal limitation, information and communication technology is today considered as the axis and key to sustained development and as the most important criterion for development which has reshaped the world and life patterns and it is, in fact, considered both the cause and the effect of development. identifying and proper using of new opportunities for sustained develop...

An original approach, termed Divide-and-Evolve is proposed to hybridize Evolutionary Algorithms (EAs) with Operational Research (OR) methods in the domain of Temporal Planning Problems (TPPs). Whereas standard Memetic Algorithms use local search methods to improve the evolutionary solutions, and thus fail when the local method stops working on the complete problem, the Divide-and-Evolve approac...

In this paper, we propose an effective clustering method, HRK (Hierarchical agglomerative and Recursive K-means clustering), to predict the short-term stock price movements after the release of financial reports. The proposed method consists of three phases. First, we convert each financial report into a feature vector and use the hierarchical agglomerative clustering method to divide the conve...

It is very difficult and expensive to replace sensor node battery in wireless sensor network in many critical conditions such as bridge supervising, resource exploration in hostile locations, and wildlife safety, etc. The natural choice in such situations is to maximize network lifetime. One such approach is to divide the sensing area of wireless sensor network into clusters to achieve high ene...

The paper devotes to the problem of overcoming of the digital divide in the Sub Saharan African States. On the example of Kenya the author speaks about the comparative success of the development of the information technologies in Africa and in turn underlines the most significant obstacles on the way of African states to the global information society and suggests the means how to overcome them.
