Research ArticleOpen accessIn the keywordsEmbedding Malaysian House Red Ant Behavior into an Ant Colony SystemZ. A. Othman, H. M. Rais, A. R. HamdanProblem statement: Ant Colony System (ACS) is the most popular algorithm used to find a shortest path solution in Traveling Salesman Problem (TSP). Several ACS versions have been proposed which aim to achieve an optimum solution by adjusting pheromone levels. However, it still has a room on an improvement. This research aims to improve the algorithm by embedding individual Malaysian … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,961 accessesView PDFCite
Research ArticleOpen accessIn the abstractAN IN-HOUSE COMPUTER-BASED DATA ACQUISITION AND CONTROL SYSTEM FOR ANAEROBIC FERMENTATION PROCESSESE. A. Echiegu, A. E. GhalyA computer-based Data Acquisition and Control System (DACS) capable of monitoring the temperature, pH and gas production as well as maintaining a pre-determined temperature profile and feeding regime in anaerobic reactors was developed and tested. The hardware for the DACS was a series-based system consisting of a host processor which drives three modules-a digital input mode (MODULE 255), an analog … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 17 Nov 2014 · 6,907 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Method for Testing Digital to Analog Converter in Static RangeK. Hariharan, S. Gouthamraj, B. Subramaniam et al.Problem statement: Linearity testing methods for DAC usually involves usage of non-linear analog components, which are indeed prone to various errors. Few other testing methodologies involve complex circuitry for measuring exactitude of DAC. Practically, it is difficult to build those as Built In Self Test (BIST) due to complexity of calculation, which demands more usage of ALU (or core of … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,458 accessesView PDFCite
