A cost-effectiveness analysis of syphilis screening was performed. Strategies included no screening, universal testing at military entrance processing stations, universal testing at basic training centers, and contracting centralized screening. Probabilities derived from data retained on recruit applicants from 1989 through 1991 (N = 1,588,143) and from the published literature were used. Cost estimates were derived from costs incurred by the military and costs projected from implementing new strategies. Sensitivity analyses were performed. Modifying the existing contract for human immunodeficiency virus screening to include syphilis screening would maximize the effectiveness of screening at a cost to the Department of Defense of $9.52 per additional year of service received. The no-screening option was significantly more cost-saving than the current method of testing. Syphilis is rare and treatable, and individuals with syphilis will be identified by other means in many cases. Syphilis screening of recruit applicants at the military entrance processing stations should cease, saving the military $2,541,000 per year.
The routing protocol is an applied standard to determine the communication scheme of different entities with each other to transfer and process the desired data in considerable time via the best routes from the source to the destination. This paper presents the performance evaluation and discrimination for various parameters of two different routing protocols using the Root Relative Squared Error (RRSE). The two protocols under study are Ad-hoc On-demand Distance Vector (AODV), and Ad-hoc On-demand Multipath Distance Vector (AOMDV). The literature reviews reveals the simulation results of number of nodes that varies approximately between 5 to 100 nodes. Therefore, that he simulation results will be analyzed for two different experiment as follows the first, the effect of initial node energy variation between 50 to 100 Joules at a fixed network size. Whereas in the second, reveals the impact of the network size, which varies between 50 to 450 nodes at constant initial node energy that it is tested between 50 to 100 Joules. The obtained results of the selected parameters prove that the AOMDV protocol is more efficient, robust, and reliable than the AODV protocol for the first experiment, while the RRSE values of AODV are better for the second. Moreover, the proposed technique based on the RRSE algorithm advantageous to compare the two routing protocols.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
