BACKGROUND Among the major pests of maize in India are two stem borers, Chilo partellus (Swinhoe) and Sesamia inferens (Walker), and an earworm, Helicoverpa armigera (Hübner). As a pest control strategy, transgenic Bacillus thuringiensis (Bt) maize hybrids are undergoing regulatory trials in India. We have determined the sensitivity of the target(More)
Internet has become an integrated carrier gradually, which has multi business such as data, voice, video, multimedia and so on. New multimedia applications require the network to guarantee quality of service. MPLS network has the capability of routing with some specific constraints for supporting desired QoS, out of which bandwidth is the most important(More)
This paper presents the design & simulation of an Optical Fiber Bragg Grating (OFBG) sensor for stress, strain measurement and also demonstrates the methodology to arrive at the optimal grating pitch dimensions for a given interrogating wavelength. The wavelength chosen for interrogation of the Fiber Bragg Grating (FBG) sensor is from the third window so as(More)
MPLS enables service providers to meet challenges brought about by explosive growth and provides the opportunity for differentiated services without necessitating the sacrifice of the existing infrastructure. MPLS is a highly scalable data carrying mechanism which forwards packets to outgoing interface based only on label value .MPLS network has the(More)
This paper presents a brief overview of a patron queuing system in the communication sectors. Businesses have been faced with an ever-increasing demand from customers for convenient services. Customers do not want to spend their time waiting in a long queue. They want quick service because time is money & money is business. In order to meet this demand,(More)
This paper proposes a new dynamic packet scheduling scheme which guarantees the delay and jitter properties of differentiated services (DiffServ) network for both real time and non-real time traffics. The proposed dynamic packet scheduling algorithm uses a new weighted computation scheme known as dynamic benefit weighted scheduling (DB-WS) which is loosely(More)
With increasing global reliance on the Internet as a medium to transmit information comes an increased risk of cyber-attack. Social networking sites are the most popular tools in internet for social interaction between the people. Online social networks (OSNs) have rapidly become a prominent and widely used service, offering a wealth of personal and(More)
Orthogonal Frequency Division Multiplexing (OFDM) systems are particularly sensitive to carrier frequency offset (CFO) and Inphase and Quadrature (I/Q) imbalance. These parameters degrade the performance of OFDM-based system as they destroy the orthogonality between sub-carriers. In this paper, we designed an estimation algorithm which is based on non data(More)
In this paper, we design a new dynamic packet scheduling scheme suitable for differentiated service (DiffServ) network. Designed dynamic benefit weighted scheduling (DBWS) uses a dynamic weighted computation scheme loosely based on weighted round robin (WRR) policy. It predicts the weight required by expedited forwarding (EF) service for the current time(More)
