In this paper, a novel multi-objective bus stop location model is proposed, which considers not only the coverage of demand and minimization of access time but also the necessities of suitable stops for transit network design phase. Three objective functions are considered including minimizing (I) sum of the total access distance (time), (II) the weighted combination of stops, and (III) the num...
This paper presents a novel multi-objective mathematical model of a periodic vehicle routing problem (PVRP) in a competitive situation for obtaining more sales. In such a situation, the reaching time to customers affects the sale amount therefore, distributors intend to service customers earlier than other rivals for obtaining the maximum sale. Moreover, a partial driver’s benefit is related...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
objective this is the first report of cns involvement by the new influenza virus (influenza a [h1n1]) in iran. the patient was a 10-year-old boy with chief complaints of fever, malaise, and cranial nerve involvement, resulting in respiratory muscle paralysis and intubation. this shows that the new influenza virus, as well as the seasonal flu, can cause neurologic complications; however, the sev...
background: the clinical manifestations and outcome of influenza infection differ between various patients in the world. the purpose of this study was to assess the clinical manifestations of patients with confirmed or suspected novel h1n1 flu infection in sari, north of iran. methods: from september 2009 to january 2010, the patients’ data were collected by retrospective chart review of medica...
Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...

swine flu is a new emerging infectious disease originating in mexico . this novel influenza is the present pandemic disease of the world. in this brief paper, the author discusses on conjunctivitis and other eye manifestations in swine flu. iranian journal of ophthalmology 200921(3):3-4 © 2009 by the iranian society of ophthalmology
INTRODUCTION Epicardial cardiac resynchronization therapy (CRT) permits unrestricted electrode positioning. However, this requires surgical placement of device leads and the risk of unwanted phrenic nerve stimulation. We hypothesized that shielded electrodes can capture myocardium without extracardiac stimulation. METHODS In 6 dog and 5 swine experiments, we used a percutaneous approach to ac...
Conventional tag cloud systems can only present the frequency of tags and the connection of tags and tag clusters, but cannot properly express the strength of the relationships. In this paper we tackle this problem by improving the representation of tag clustering. We combine the advantages of conventional systems to create a multi-level interactive tag cloud system using clustering scheme. In ...
