A Fuzzy based Routing Protocol for Delay Tolerant Network
Neelam Malik,Shailender Gupta,Bharat Bhushan 보안공학연구지원센터 2015 International Journal of Grid and Distributed Comp Vol.8 No.1
Delay Tolerant Network (DTN) is a wireless ad hoc network that intends to provide communication between pair of nodes in spite of having intermittent connectivity and long delays. The nodes are buffer and energy constrained. To provide communication in such scenario, a sturdy routing mechanism is needed. In this paper we propose a new routing technique based on fuzzy logic for intermittently connected network. Also an effort has been made to evaluate the performance of the proposed routing strategy in realistic environment (having obstacles) in MATLAB. The simulation results show that the performance of the network is improved using fuzzy logic based routing strategy and the results of realistic environment are quite different from idealistic environment.

Response in a modified reciprocal recurrent selection scheme for egg production was evaluated considering variable family sizes and genetic correlation between purebred and crossbred half sisters. The criteria of selection of purebred breeders included pullet's own performance, purebred full and half sisters and crossbred half sister's performance. Heritability of egg production of crossbreds (aggregate genotype) and purebred's was assumed to be 0.2 and genetic correlation between purebred and crossbred half sisters ($r_{pc}$) as 0.1, 0.2, 0.3, 0.4, 0.5, 1.0, -0.1, -0.2, -0.3, -0.4, -0.5 and -1.0. Number of dams per sire to produce purebred and crossbred progenies assumed to be 5, 6, 7, 8, while number of purebred female progeny ($N_p$) and crossbred progeny ($N_c$) per dam were considered to be 3, 4, 5 and 6 in each case. Considering phenotypic variance as unity, selection indices were constructed for different combinations of dams and progeny for each value of $r_{pc}$. Following selection index theory, response in crossbred and purebred for egg production was computed. Results indicated that response in crossbreds depended mainly on crossbred family size and also on magnitude of$r_{pc}$ irrespective of its direction, and response was greater with large crossbred family size than the purebred families. Correlated response in purebreds depends both on magnitude and direction of $r_{pc}$ and was expected to be greater with large purebred family size only. Inclusion of purebred information increased the accuracy of selection for crossbred response for higher magnitude of$r_{pc}$ irrespective of its direction. Present results indicate that desirable response in both crossbred and purebred performance is a function of $r_{pc}$ and family sizes. The ratio of crossbred and purebred family sizes can be optimized depending on the objective of improving the performance of crossbreds and/or of purebreds.
Spondylodiscitis Complicated by the Ingestion of a Button Battery: a Case Report

A one-and-a-half year old boy who presented with a cough, irritability, and refusal of food was found to have an impacted foreign body in his upper esophagus. We present the radiologic findings of the foreign body (a button battery) impacted in the upper esophagus and its complications; namely, mediastinitis and spondylodiscitis after endoscopic removal. Further, plain radiograph and MR imaging findings are discussed along with literature review.
