Research ArticleOpen accessIn the keywordsSpeech Signal Analysis in Phase DomainHusne Ara Chowdhury, Mohammad Shahidur RahmanSpeech signal analysis based on the Phase Spectrum (PS) in the recent years becomes more popular to the researchers due to its attractive properties. Though some problem arises during its processing but appropriate modification gives the useful result. In this study, we proposed a new method of speech signal analysis based on its phase spectral representation. After analyzing the PS … …Journal of Computer Science, Vol. 16, Issue 8 · 10 Aug 2020 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Pulsed Electromagnetic Field Exposure on Fracture Healing Through the Wnt Signal PathwayUmiatin U, Ismail Hadisoebroto Dilogo, Puji Sari, Sastra Kusuma WijayaPulsed Electromagnetic Fields (PEMF) is reported to encourage the healing of nonunion fractures. However, the mechanism by which this occurs is still not known. Wnt signaling pathways are believed to be important signaling pathways in bone formation. This study will evaluate the healing of delayed union femur fracture, given PEMF exposure. 48 Spraque Dawley rats were fracturized at the left … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 14 Dec 2020 · 6,653 accessesView PDFCite
Research ArticleOpen accessIn the abstractMESSAGE AUTHENTICATION CODE BASED SECURE GROUP KEY MANAGEMENT PROTOCOL FOR MOBILE AD HOC NETWORKST. Peer Meera Labbai, V. RajamaniA mobile ad hoc network is a group of nodes which are communicating with each other with the use of radio frequencies. When there is high movement of mobile nodes, the nodes find difficult to reach other nodes. If the data are exchanged between nodes when there is high mobility, the data may be lost in transit. Therefore the security … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,727 accessesView PDFCite
Research ArticleOpen accessIn the abstractSitagliptin Impairs Healing of Experimentally Induced Gastric Ulcers Via inhibition of iNOS and COX-2 ExpressionAmina Unis, Eman AbdelzaherGastric ulcer healing is a complex process that is regulated by several promoting factors including COX-2 and iNOS. Diabetes mellitus is usually associated with delayed gastric ulcer healing. Hence, the current study was designed to investigate the effect of sitagliptin (dipeptidyl peptidase-4 inhibitor) on gastric ulcer healing and expression of iNOS and COX-2 in rat stomach.The study was conducted on … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 3 · 4 Sep 2013 · 7,436 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnd to End Delay Improvement in Heterogeneous Multicast Network using Genetic OptimizationV. Chandrasekar, K. BaskaranProblem statement: Multicast is a concept of group communication which refers to transmitting the same data or messages from a source to multiple destinations in the network. This one-to-many group communication is a generalization of the concepts of one-to-one unicast and one-to-all broadcast. To deliver data from the sender to all receivers efficiently, routing plays an important role in multicast … …Journal of Computer Science, Vol. 8, Issue 9 · 13 Aug 2012 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractLevamisole Enhances Cell-Mediated Immune Responses and Reduces Shedding of H9N2 Avian Influenza Virus in Japanese Quails (Coturnix coturnix japonica)Tahoora Shomali, Najmeh Mosleh, Arash AlaeddiniProblem statement: Regarding the role of Japanese quails (Coturnix coturnix japonica) in reassortment and spreading of avian influenza (AI) viruses and inadequate protection of vaccination in this species, the present study aimed to evaluate the effect of levamisole as an immunomodulatory agent on cell-mediated immunity (CMI), antibody responses and shedding of H9N2 AI virus in experimentally infected quails. Approach: On … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 1 · 6 Mar 2012 · 7,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractRange Detection Multicast Routing Protocol for Mobile Ad-Hoc NetworksR. Velumani, K. DuraiswamyProblem statement: Many efforts have been implemented towards the Group membership management on multicast routing in MANETs, but the difficulties associated with Group membership management are still existed. Approach: Maintaining endurance of Group Leader (GL) in multicasting routing has been a great challenge to all the protocol having been invented so far. Results: This study provides the RDMP algorithm for … …Journal of Computer Science, Vol. 8, Issue 4 · 10 Feb 2012 · 6,486 accessesView PDFCite
Research ArticleOpen accessIn the abstractClinical Signs of Hairballs in Cats Fed a Diet Enriched with CelluloseA. C. Beynen, J. Middelkoop, D. H.J. SarisProblem statement: The intake of cellulose may delay gastric emptying and raise the intestinal transit rate. These effects could antagonize hairball formation. Thus, it was hypothesized that a diet enriched with a cellulose preparation (Arbocel BWW40®), forming a completely insoluble fiber network, would diminish the severity of clinical symptoms of hairballs in cats. Approach: In a double-blind, placebo-controlled trial with … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 8 Aug 2011 · 11,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Logic Controller for Wireless Video TransmissionK. P. Rajesh, K. S. RamaswamiProblem statement: As the Variable Bit Rate (VBR) is high in MPEG, the video experienced long delay and unexpected data loss. In wireless channel, due to noise and interference of other signals transmission rate cannot be predicted. Approach: In this paper we proposed an intelligent fuzzy logic controller for transmission of Moving Picture Expert Group (MPEG-4) video signals over wireless … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Computation Power by Reducing Query Response Time in Peer-to-Peer EnvironmentVelvizhi Nandagopal, D. ManjulaProblem statement: The Peer-to-Peer (P2P) was an emerging model and was being widely adopted in today’s internet computing.P2P traffic contributes the largest portion of the internet traffic which was unnecessary and led to delay. In existing Scalable Bipartite Overlay (SBO) network, Out of “N” peers, one group of peers were probing the messages (or) queries whereas the other group of … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,598 accessesView PDFCite
