An Improved Stock Price Prediction using Hybrid Market Indicators

In this paper the effect of hybrid market indicators is examined for an improved stock price prediction. The hybrid market indicators consist of technical, fundamental and expert opinion variables as input to artificial neural networks model. The empirical results obtained with published stock data of Dell and Nokia obtained from New York Stock Exchange shows that the proposed model can be effective to improve accuracy of stock price prediction

PQ TREES, CONSECUTIVE ONES PROBLEM AND APPLICATIONS

A PQ tree is an advanced tree–based data structure, which represents a family of permutations on a set of elements. In this research article, we considered the significance of PQ trees and the Consecutive ones Problem to Computer Science and bioinformatics and their various applications. We also went further to demonstrate the operations of the characteristics of the Consecutive ones property by simulation, using high level programming languages. Attempt was also made at developing a PQ tree–Consecutive Ones analyzer, which could be instrumental not only as an educative tool to inquisitive students, but also serve as an important tool in developing clustering software in the field of bioinformatics and other application domains, with respect to solving real life problems

Critical Analysis of Decision Making Experience with a Machine Learning Approach in Playing Ayo Game

The major goal in defining and examining game scenarios is to find good strategies as solutions to the game. A plausible solution is a recommendation to the players on how to play the game, which is represented as strategies guided by the various choices available to the players. These choices invariably compel the players (decision makers) to execute an action following some conscious tactics. In this paper, we proposed a refinement-based heuristic as a machine learning technique for human-like decision making in playing Ayo game. The result showed that our machine learning technique is more adaptable and more responsive in making decision than human intelligence. The technique has the advantage that a search is astutely conducted in a shallow horizon game tree. Our simulation was tested against Awale shareware and an appealing result was obtained

Computational Analysis of Anopheles Gambiae Metabolism to Facilitate Insecticidal Target and Complex Resistance Mechanism Discovery

Insecticide resistance is a genetic characteristic involving changes in one or more insect genes. It is also a major public health challenge combating world efforts on malaria control and strategies. The Malaria vector, Anopheles gambiae (A. gambiae) has formed resistance to the existing classes of insecticides, especially pyrethroid, the only class approved for Indoor Residual Spray (IRS) and Long-Lasting Insecticide Treated Net (LLITNs). Identification of novel insecticidal targets for the development of more effective insecticides is therefore urgent. However, deciding which gene products are ideal insecticidal targets remains a difficult task in the search. To this end, it has been shown that the dissection and comprehensive studies of biochemical metabolic networks has great potential to effectively and specifically identify and extract essential enzymes as potential insecticidal targets. Using the PathoLogic programme, AnoCyc, a pathway/genome database (PGDB) for A. gambiae AgamP3 was constructed, using its annotated genomic sequence and other annotated information from ANOBASE, VECTORBASE, UNIPROT and KEGG databases. Furthermore, additional annotations to proteins annotated as “hypothetical” was gathered using specifically two annotation tools from the DKFZ HUSAR open servers, namely GOPET and DomainSweep and present a more comprehensive annotated PGDB for A. gambiae AgamP3. The resulting PGDB for A. gambiae AgamP3 has been deployed under the www.bioCyc.org databases. Next, a graph based model that analyzed the topology of the metabolic network of Anopheles gambiae was developed to determine the essential enzymatic reactions in the networks. A refined list of 61 new potential insecticidal candidate targets was obtained, which include one clinically validated insecticidal target and host of others with biological evidence in the literature. Finally, the biochemical network of A. gambiae was overlaid with two gene expression data obtained from the treatment of A. gambiae with pyrethroid (permethrin) to elucidate some tightly linked resistance genes and deduce computationally, for the first time, its resistance mechanism(s) toward this insecticid

Development of Electronic Government Procurement (e-GP) System for Nigeria Public Sector.

Business-to-business electronic procurement success in business organizations (private sectors) has been a major driving force for government organizations (public sectors) in developed nations to adopt electronic government procurement in order to reduce cost and improve administrative efficiency. E-procurement within the government is recognized to be the main area of government-to-business that needs to be exploited by government of developing nations. In this paper, we examined the drawbacks of existing procurement process in Nigeria with a view to offering an improved approach. A prototype e-GP system was designed and developed to eliminate the associated bottlenecks with existing system and showcase the attendant benefits of the proposed system which can lead to an improved procurement cycle process flow
