this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...

User studies have revealed that programmers face several obstacles when learning application programming interfaces (APIs). A considerable part of such difficulties relate to discovery of API elements and the relationships among them. To address discoverability problems, we show how to complement APIs with design annotations, which document design decisions in a program-processable form for typ...

In some long term studies, a series of dependent and possibly truncated lifetime data may be observed. Suppose that the lifetimes have a common continuous distribution function F. A popular stochastic measure of the distance between the density function f of the lifetimes and its kernel estimate fn is the integrated square error (ISE). In this paper, we derive a central limit theorem for t...

In this paper, a new hybrid routing protocol is presented for low power Wireless Sensor Networks (WSNs). The new system uses an integrated piezoelectric energy harvester to increase the network lifetime. Power dissipation is one of the most important factors affecting lifetime of a WSN. An innovative cluster head selection technique using Cuckoo optimization algorithm has been used in the desig...

modern business organizations have appreciated the significance of having competitive advantage through the delivery of continuous improvement towards the customers, and being knowledge-oriented. indisputably, knowledge management (km) plays a key role in the success of customer relationship management (crm). in this regard, customer knowledge management (ckm) is a newly developed concept that ...

Most existing integrated circuit reliability models assume a uniform, typically worst-case, operating temperature, but temporal and spatial temperature variations affect expected device lifetime. As a result, design decisions and dynamic thermal management techniques using worst-case models are pessimistic and result in excessive design margins and unnecessary runtime engagement (and associated...

Most existing integrated circuit (IC) reliability models assume a uniform, typically worst-case, operating temperature, but temporal and spatial temperature variations affect expected device lifetime. As a result, design decisions and dynamic thermal management (DTM) techniques using worst-case models are pessimistic and result in excessive design margins and unnecessary runtime engagement of c...

in order to evaluate the efficiency of biocontrol agents of corn stem borer ,ostrinia nubilalis, experiment was conducted in a randomized complete block by five treatments and four replication, including, indoxacarb (avant)®, trichogrammawasps, bacillus thuringiensis var: kurstaki, integration of trichogramma sp. and bt., and control as treatments number 1 to 5. in treatments with parasitoid re...

environmental protection is a key element in urban management. due to complex relationships between human and environment in metropolises the importance of environment is ever-increasing. in this paper the current situation of environment in tehran metropolis including air, water, biodiversity and human habitat along with the most crucial threats, their effect as well as the associated agencies...
