Research ArticleOpen accessIn the author namesHarmonic Mean Projection Shape Transform for Leaf ClassificationSophia Jamila Zahra, Riza Sulaiman, Seyed M.M. Kahaki, Anton Satria PrabuwonoShape feature extraction has emerged as an important part of computer vision and image processing applications. Identification of shape objects in huge data based on shape similarity still remains a challenging problem due to the similarity of the shapes and existing of classes with similar contour information. This paper presents to investigate the shape analysis for plant leaf classification by … …Journal of Computer Science, Vol. 16, Issue 9 · 13 Sep 2020 · 6,854 accessesView PDF Cite

Research ArticleOpen accessIn the author namesModulatory Effects of Bryophyllum Pinnatum Leaves Extract on Peroxidation Indices of CCl4 Induced-Hepatotoxicity in Wistar Albino RatsChioma Assumpta Anosike, Sophia Uyo Mokwunye, Victor Eshu Okpashi, Obiorah AbonyiThis research investigated the modulatory effect of methanol extract of Bryophyllum pinnatum leaves on peroxidation indices of CCl4-induced hepatotoxicity. Thirty rats of average weight 150g divided into six groups of 5 rats each were used for the study. Group one (control) received water and paraffin for ten days. Group two (treatment control) received water only, group 3 (standard control), received … …American Journal of Pharmacology and Toxicology, Vol. 12, Issue 3 · 17 Dec 2017 · 7,448 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAN EFFICIENT POWER REDUCTION TECHNIQUE IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM USING TONE RESERVATIONV. Nandalal, S. SophiaIn a basic communication system, the data’s are modulated onto a single carrier frequency. The available bandwidth is then totally occupied by each symbol. This kind of system can lead to Inter-Symbol-Interference (ISI) in case of frequency selective fading. The basic idea of Orthogonal Frequency Division Multiplexing (OFDM) is to divide the available spectrum into several orthogonal sub channels so … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,471 accessesView PDF Cite

Research ArticleOpen accessIn the author namesMonitoring Water Quality Parameters of the Transboundry River NestosPsilovikos Aris, Margoni Sophia, Psilovikos AntoniosThe Nestos/Mesta river, shared by Greece and Bulgaria, needs monitoring system along its course for sustainable management and environmental preservation. Such a system, known as R.E.MO.S., was installed in the year 2000 and operates since then on a 24 h basis at a station in the river deltas channel. It records water level, water and air temperature, conductivity, redox potential … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,181 accessesView PDF Cite

InvestigationOpen accessIn the abstractEvaluation of Black Currant Cultivars Resistance to Aphis grossulariae Kalt. and Effectiveness of Water Extracts of Artemisia Absinthium L. and Tanacetum Vulgare L. Against this PestNatalya Gennadievna Andrianova, Tatyana Vladimirovna Likhacheva, Tatyana Olegovna SirotinaThis study consisted in revealing the possibility of using two ecologically safe methods to control gooseberry aphid (Aphis grossulariae Kalt.) in black currant cultivars: selection aphid resistant cultivars and the use of plant water extracts of wormwood (Artemisia absinthium L.) and tansy (Tanacetum vulgare L.) in the arid zone of Central Kazakhstan for protection against aphid. The study of the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 26 Mar 2018 · 7,391 accessesView PDF Cite
