according to the low efficiency of irrigation and drainage networks and water distribution in iran, simulating water flow and sensitivity structures and networks is considered as a new approach to evaluate the performance hydroelectric projects in the country. in this study, because of reduced water supply and distribution, especially in downstream irrigation and drainage networks varamin to ev...

extended abstract abstract pressure management is an effective method for water demand management. for evaluation of the effects of pressure changes on leakage level of water networks, the favad equation is usually used. however, in this equation, exponent of pressure parameter (n) needs to be determined. for estimation of n, either some information about the leak opening is necessary or networ...

We consider a family of long-range percolation models (Gp)p>0 on Zd allowing dependence between edges and having these connectivity properties for p ∈ (1/d,∞): (i) the degree distribution of vertices in Gp has a power law distribution, (ii) the graph distance between points x and y is bounded by a multiple of logpd logpd |x − y| with probability 1 − o(1), and (iii) an adversary can delete a rel...

background: tubulin protein being the fundamental unit of microtubules is actively involved in cell division thus making them a potential anti-cancer drug target. in spite of many reported drugs against tubulin, few of them have started developing resistance in human β-tubulin due to amino acid substitutions. methods: in this study we generated three mutants (f270v, a364t and q292e) using model...

Data dissemination or diffusion service is the process of distributing a certain amount of information to the users such as vehicle drivers or mobile users especially in wireless networks. It also plays a significant role in numerous applications of Vehicular Ad hoc Networks (VANETs). Data Dissemination problem has been addressed by many researchers so far in many contexts. This paper presents ...

In 2000, Lee and Chang proposed a user identification scheme with key distribution preserving anonymity for distributed computer networks. Recently, Wu and Hsu pointed out that there are two weaknesses in the LeeChang scheme. They further not only proposed a new scheme to remedy the security leaks of the Lee-Chang scheme, but also reduced computation complexities and communication cost as compa...

This work consists in a numerically evaluation of elastic fields distribution, caused by intrinsic dislocation networks placed at a nanometric trilayers interfaces, in order to estimate their influence on the surface topology during heterostructure operation. The organization of nanostructures is ensured by the knowledge of different elastic fields caused by buried dislocation networks and calc...

Proper distribution of mitochondria within axons and at synapses is critical for neuronal function. While one-third of axonal mitochondria are mobile, a large proportion remains in a stationary phase. However, the mechanisms controlling mitochondrial docking within axons remain elusive. Here, we report a role for axon-targeted syntaphilin (SNPH) in mitochondrial docking through its interaction ...

The Transportation Research Forum, founded in 1958, is an independent, nonprofit organization of transportation professionals who conduct, use, and benefit from research. Its purpose is to provide an impartial meeting ground for carriers, shippers, government officials, consultants, university researchers, suppliers, and others seeking exchange of information and ideas related to both passenger...
