Correlative Analysis of Data and Functions of Neuronal Synapse  [PDF]
T. R. Gopalakrishnan Nair, A. Baby Jerald
Journal of Behavioral and Brain Science (JBBS) , 2013, DOI: 10.4236/jbbs.2013.32027
Abstract:

Until recently, the synaptic transmission and excitatory amino acid transporters activation of neurons are very well discussed in the previous studies and are considered to be the two distinct features of Synapse. It is also found that a large number of interactions take place in the domain of ionic exchanges and protein interactions in synapses. It is evolutionary to have destined to release of Neurotransmitters to conduct an impulse to the other consecutive neurons, which forms the most important characteristic of synapse. From the popular perspective, it has been identified that detailed theoretical closer correlation of data produced through various studies about synapse can unravel many mysteries related to functions of synapse. Hence, this research paper tries to concentrate on a selected group of prominent characteristics and properties of synapse and also highlights some noteworthy discoveries, emphasizing the influential capabilities of them in the thought process and improving the knowledge of the field. It also highlights the expressive properties and forms of synapse brought out through the evidences available in sparse to dense data in a correlational way.

Water Molecules in the Carbon C60 Confined Space  [PDF]
M. Baskar, N. Sathyan, T. R. Gopalakrishnan Nair
Journal of Biophysical Chemistry (JBPC) , 2018, DOI: 10.4236/jbpc.2018.92002
Abstract: Experimental scenario of the world being successful in planting water molecule at binary level in fullerene C70 is of utmost importance to pursue the theoretical properties of predictive triple water molecules and poly water molecules in Vander Waals confined space like fullerenes. Here, we present a paper in these lines of exploration of embedding triple water molecules in a Carbon confined space through the studies of behavior of three water molecules in Fullerene C60 by ab-initio methods. This heterogeneous system manifests cyclic hydrogen bonds which may be working with flipping actions. The unusual structural property of water trimers is reported. There exists a dipole moment of 0.9 ± 0.1 Debye which indicates the probable semiconductor properties.
Stochastic Model Based Proxy Servers Architecture for VoD to Achieve Reduced Client Waiting Time
T. R. GopalaKrishnan nair,M. Dakshayini
International Journal of Computer Science Issues , 2010,
Abstract: In a video on demand system, the main video repository may be far away from the user and generally has limited streaming capacities. Since a high quality video's size is huge, it requires high bandwidth for streaming over the internet. In order to achieve a higher video hit ratio, reduced client waiting time, distributed server's architecture can be used, in which multiple local servers are placed close to clients and, based on their regional demands video contents are cached dynamically from the main server. As the cost of proxy server is decreasing and demand for reduced waiting time is increasing day by day, newer architectures are explored, innovative schemes are arrived at. In this paper we present novel 3 layer architecture, includes main multimedia server, a Tracker and Proxy servers. This architecture targets to optimize the client waiting time. We also propose an efficient prefix caching and load sharing algorithm at the proxy server to allocate the cache according to regional popularity of the video. The simulation results demonstrate that it achieves significantly lower client's waiting time, when compared to the other existing algorithms.
A Strategy to enable Prefix of Multicast VoD through dynamic buffer allocation
T. R. GopalaKrishnan nair,P. Jayarekha
International Journal of Computer Science Issues , 2010,
Abstract: In this paper we have proposed a dynamic buffer allocation algorithm for the prefix, based on the popularity of the videos. More cache blocks are allocated for most popular videos and a few cache blocks are allocated for less popular videos. Buffer utilization is also maximized irrespective of the load on the Video-on-Demand system. Overload can lead the server getting slowed down. By storing the first few seconds of popular video clips, a multimedia local server can shield the users from the delay, throughput, and loss properties of the path between the local server and the central server. The key idea of controlled multicast is used to allow clients to share a segment of a video stream even when the requests arrive at different times. This dynamic buffer allocation algorithm is simulated and its performance is evaluated based on the buffer utilization by multimedia servers and average buffer allocation for the most popular videos. Our simulation results shows efficient utilization of network bandwidth and reduced hard disk utilization hence resulting in increase in the number of requests being served.

Mapping General System Characteristics to Non- Functional Requirements
A. Keshav Bharadwaj,T. R. Gopalakrishnan Nair
Computer Science , 2010,
Abstract: The Function point analysis (FPA) method is the preferred scheme of estimation for project managers to determine the size, effort, schedule, resource loading and other such parameters. The FPA method by International Function Point Users Group (IFPUG) has captured the critical implementation features of an application through fourteen general system characteristics. However, Non- functional requirements (NFRs) such as functionality, reliability, efficiency, usability, maintainability, portability, etc. have not been included in the FPA estimation method. This paper discusses some of the NFRs and tries to determine a degree of influence for each of them. An attempt to factor the NFRs into estimation has been made. This approach needs to be validated with data collection and analysis.
Effective Defect Prevention Approach in Software Process for Achieving Better Quality Levels
V. Suma,T. R. Gopalakrishnan Nair
Computer Science , 2010,
Abstract: Defect prevention is the most vital but habitually neglected facet of software quality assurance in any project. If functional at all stages of software development, it can condense the time, overheads and wherewithal entailed to engineer a high quality product. The key challenge of an IT industry is to engineer a software product with minimum post deployment defects. This effort is an analysis based on data obtained for five selected projects from leading software companies of varying software production competence. The main aim of this paper is to provide information on various methods and practices supporting defect detection and prevention leading to thriving software generation. The defect prevention technique unearths 99% of defects. Inspection is found to be an essential technique in generating ideal software generation in factories through enhanced methodologies of abetted and unaided inspection schedules. On an average 13 % to 15% of inspection and 25% - 30% of testing out of whole project effort time is required for 99% - 99.75% of defect elimination. A comparison of the end results for the five selected projects between the companies is also brought about throwing light on the possibility of a particular company to position itself with an appropriate complementary ratio of inspection testing.
