The Efficiency of Solar Panel: Case Study of Cross River State University of Technology, Nigeria
Abstract: We use two solar panels; mono-crystalline and poly-crystalline solar panel, to determine how ambient temperature affects the efficiency of photovoltaic solar panels in Cross River State University of Technology within Calabar south metropolis. This shows that the efficiency of the solar planes actually decreases with increase in temperature and which also depends on the time interval. Keywords: Mono-crystalline solar panel, polycrystalline solar panel, ambient temperature

Performance Analysis of DNA Sequencing Using Smith-Waterman Algorithm on FPGA
Abstract: The Smith-Waterman algorithm is the most accurate and optimal alignment algorithm for DNA sequencing. It is utilized to locate the ideal local alignment between two sequences. While looking sequence databases that may contain billions of sequences, this algorithm turns out to be computationally costly and tedious. Smith-Waterman algorithm needs additional memory space and this constrains the extent of a sequence to be aligned. In this study we will implement the …
