earthquake location process has an important role in any seismological applications including seismic tomography etc. the relationship between the travel-time of seismic phases and earthquake hypocenter (latitude, longitude, depth) and origin-time is non-linear and many different linearized methods have been implemented in recent years to linearize the relationship. the principal underlying lin...

How can we identify the epidemiologically high-risk communities in a metapopulation network? The network centrality measure, which quantifies the relative importance of each location, is commonly utilized for this purpose. As the disease invasion condition is given from the basic reproductive ratio R0, we have introduced a novel centrality measure based on the sensitivity analysis of this R0 an...

In this paper we present a location-based routing protocol called Partial-partition Avoiding Geographic Routing-Mobile (PAGER-M), for mobile sensor networks that consist of frequently moving sensors. The protocol uses the location information of sensors and the base station to assign a cost function to each sensor node, which is close to the Euclidean length of a sensor node’s shortest path to ...

One of the most critical barriers to widespread adoption of electric cars is the lack of charging station infrastructure. Although it is expected that a sufficient number of charging stations will be constructed eventually, due to various practical reasons they may have to be introduced gradually over time. In this paper, we formulate a multi-period optimization model based on a flow-refueling ...

the present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. soot concentrations inside the combustor are measured by filter paper technique. the simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and soo...

In order to prolong the lifetime of sensor nodes, wireless sensor networks are partitioned into clusters. The most of the proposed Equal Clustering algorithms do not consider location of the base station. This situation causes hot spots or energy hole problem in multi-hop data forwarding. Unequal clustering mechanisms, which are designed by considering the location of the base station to solve ...

Interesting application in wireless sensor network is Object Tracking Sensor Network...

Increasing sales of conventional fuel-based vehicles are leading to an increase in carbon emissions, which dangerous the environment. To reduce these, must be replaced with alternative fuel such as hydrogen-fueled. Hydrogen can near-zero greenhouse gas emissions. However, penetration vehicles, there needs adequate infrastructure, specifically, refueling place. This paper presents a comprehensiv...

With increasing production costs and constraints, demand has increased for manufacturers to minimize maintenance cost and product transport time. We address some aspects of this problem by examining how to choose the optimal layout of stations (machines or buffers) in a production facility based on how the station layout affects the maintenance and product transport times. Specifically, we cons...
