Soft Handoff in Mobile Networks
Megha and Narendra Kumar
International Journal of Engineering Trends and Technology , 2012,
Abstract: In power controlled CDMA systems soft handoff is preferred over hard handoff strategies. This is more pronounced when the IS-95 standard is considered wherein the transmitter power is adjusted dynamically during the operation. The previous and the new wide band channels occupy the same frequency band in order to make an efficient use of bandwidth, which makes the use of soft handoff very important. Our main aim is to maintain a continuous link with the strongest signal base station otherwise a positive power control feedback would result in system problems. Soft handoff ensures a continuous link to the base station from which the strongest signal is issued.In this paper we are presenting a brief overview of the subject and some elementary concepts.

Narendra Kumar,Shikha Jain
International Journal of Computer Technology and Applications , 2012,
Abstract: The presented paper deals with how remotely managed computing and IT resources can be beneficial in the developing countries like India and Asian sub-continent countries. This paper not only defines the architectures and functionalities of cloud computing but also indicates strongly about the current demand of Cloud computing to achieve organizational and personal level of IT supports in very minimal cost with high class flexibility. The power of cloud can be used to reduce the cost of IT - resources and infrastructure with minimum risk and great efficiency.Cloud computing can be used to host a variety of applications such as vast and complicated business applications, enterprise database, e-commerce applications, payment gateway, software development and testing tools, on-demand applications and many more. Cloud computing enables organizations to increase hardware utilization rates tremendously, and to scale up the business needs instantly, without having to invest in new infrastructure, train new personnel, or license new software products. It also creates several new classes of opportunities to develop a cost effective generation of network services, in a very less amount of time and for less money. Minimization of cost is the prime need of any developing country and the cloud computing provides a full proof way to run on the cheapest technology ever developed. The cloud computing brings a new level of efficiency and economy to deliver Information Technology Resources (ITR) on demand, and in the process it opens new business models, creates new icons to work, creates new business opportunities and open up entire new face of Information Technology in a secure and cost effective environment.There are several ranges of cloud computing implementations. Cloud computing may be implemented by service providers, that is, Public clouds or in enterprise datacenters, that is, private cloud that allocate a large number of resources and capabilities so that applications can scale from one to thousands of servers in a short time. Emerging models such as virtual datacenters allow customers to reserve capacity and work with dedicated resource within a cloud, increasing the ability to manage cost and service levels. Hybrid clouds can further optimize benefits to an organization by combining the needed elements of public clouds, enterprise clouds, and enterprise datacenter technology.The Cloud Computing Architecture of a cloud solution is the structure of the system, which comprises on-premise and cloud resources, services, middleware, and software components, geo-loc
Effectiveness of FACTS Devices for Power System Stability Enhancement
Sanjiv Kumar,Dr. Narendra Kumar
International Journal of Advances in Engineering Sciences , 2011,
Abstract: — The development of the modern power system has led to an increasing complexity in the study of power systems, and also presents new challenges to power system stability, and in particular, to the aspects of transient stability and small-signal stability. Transient stability control plays a significant role in ensuring the stable operation of power systems in the event of large disturbances and faults, and is thus a significant area of research. This paper investigates the improvement of transient stability of a two-area power system, using TCSC which is an effective FACTS (Flexible AC Transmission System) device. Simulations are carried out in Matlab/Simulink environment for the two-area power system model with TCSC to analyze the effects of TCSC on transient stability performance of the system. The performance of TCSC is compared with other FACTS devices such as Static Synchronous Series Compensator (SSSC), and Static Var Compensator (SVC). The simulation results demonstrate the effectiveness and robustness of the proposed TCSC on transient stability improvement of the system.

Mathematics , 2015,
Abstract: The purpose of this paper is to study the cyclic self orthogonal codes over $\mathbb{Z}_{p^m}$. After providing the generator polynomial of cyclic self orthogonal codes over $\mathbb{Z}_{p^m}$, we give the necessary and sufficient condition for the existence of non-trivial self orthogonal codes over $\mathbb{Z}_{p^m}$ . We have also provided the number of such codes of length $n$ over $\mathbb{Z}_{p^m}$ for any $ (p,n) = 1 $.
Mathematical Modeling of Diffusion Phenomenon in a Moderately Constricted Geometry  [PDF]
Shailesh Mishra, Narendra Kumar Verma, Shafi Ullah Siddiqui
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.22027
Abstract: The incorporation of fluid flow through modelled normal and stenosed capillary-tissue exchange system has highlighted issues that may have major applications for the study of diffusion phenomenon. Results clearly demonstrate the important roles played by various physiological characteristics and diffusion variables involved in the analysis on blood flow. Assessment of the severity of the disease could be made possible through the variation of a parameter named as retention parameter. An attempt has been made to study the effects of local variation of viscosity on flow, wall-shearing stress and distribution of dissolved material in diseased artery as compared to the normal.
Analysis of macro and micro nutrients in some Indian medicinal herbs grown in Jaunpur (u.p.) soil  [PDF]
Arun Kumar, Ram Prakash Singh, Narendra Pal Singh
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.37077
Abstract: Concept of trace elements being “the Inorganic Switches” has evolved during the last several decades. Ayurveda, the traditional Indian medicinal system also emphasises the importance of minor and trace elements in human health and disease. To evaluate elemental contents of some commonly used as health promoter and fever, 5 medicine herbs (stems) namely Guduchi, Vach, Mulahati, Joytishmati and Vidhara have been analyzed for four minor (Na, K, Mg and Ca) and eight trace elements (Cr, Mn, Fe, Co, Ni, Cu, Zn and Cd) by atomic absorption spectrometry and flame photometry. Their accuracy was measured by replicate analyses. In general, elemental contents were found in varying amounts with large range. It is observed that many of medicinal herbs are enriched in one or more elements. Since these elements are bioavailable in natural form, probably in combination with organic constituents, these are likely to be easily assimilated by human bodies. Besides them, two toxic elements Ni and Cd were also found in insignificant amounts as these are likely to have originated from environmental contamination.
Range of Thresholds Used for Treatment of Neonatal Hyperbilirubinemia at Different Gestational Ages across Neonatal Units in Great Britain  [PDF]

International Journal of Clinical Medicine (IJCM) , 2011, DOI: 10.4236/ijcm.2011.25098
Abstract: Objectives: To review the range of thresholds used for treatment of neonatal jaundice at different gestational ages across neonatal units in Great Britain. To investigate the time at which the threshold values plateau, in terms of hours after birth, for various gestational ages. Methods: We contacted 72 neonatal units in Great Britain and enquired about the unit guidelines for management of neonatal jaundice. We requested a copy of the guidelines and jaundice action charts used. Levels for treatment with phototherapy and exchange transfusion for various times after birth and for different gestational ages were extracted and the data was transferred to an Excel spreadsheet. Identical values were excluded so that there was no duplication of charts. The data was analysed to explore the variation in charts used and the time at which the threshold value reached a plateau was recorded for each chart. Results: Of the 72 units contacted 46 responded with charts. Four neonatal units were using formulas and one hospital was using separate chart for every gestation. The data displayed wide variation in treatment levels (phototherapy and exchange transfusion) at 12 to 168 hours after birth in the three gestational groups studied (28, 32 and 37 weeks). For a term neonate at 72 hours of age the threshold to commence phototherapy varied between 220-370 micromol/l and the exchange transfusion threshold varied between 300-510 micromol/l. A wide variation in practice was seen for all three gestations. The median plateau time was also analysed and for phototherapy this corresponded to 72 hours for all three gestations. For exchange transfusion data the median time of plateau was highest for the term babies (72 hours) and lowest for 32 weeks gestation (48 hours). There was no reference of evidence quoted in the jaundice action charts surveyed. Conclusions: Jaundice action charts reviewed in our study showed significant variation in the threshold for treatment of neonatal jaundice. Both the studied parameters (variation in threshold and the median time to plateau) point towards the fact that the charts being used in the neonatal units are not evidence based and need modification. With the lack of standard treatment guidelines for this common neonatal problem, it is likely that neonatal units are either under or over treating a significant number of babies.
Load Balancing in IP/MPLS Networks: A Survey  [PDF]
Ravindra Kumar Singh, Narendra S. Chaudhari, Kanak Saxena
Communications and Network (CN) , 2012, DOI: 10.4236/cn.2012.42020
Abstract: The present era has witnessed tremendous growth of the Internet and various applications that are supported by it. There is an enormous pressure on Internet Service Providers (ISPs) to make available adequate services for the traffics like VoIP and Video on demand. Since the resources like computing power, bandwidth etc. are limited, the traffic needs to be engineered to properly exploit them. Due to these limitations, terms like Traffic Engineering, Quality of Service (QoS) came into existence. Traffic Engineering broadly includes techniques like multipath routing & traffic splitting to balance the load among different paths. In this document, we survey various techniques proposed for load balancing that are available on the Internet. We here try not to be exhaustive but analyze the important techniques in the literature. Present survey would help to give a new direction to the research in this realm.
