Assigning and scheduling vehicle routes in a dynamic environment is a crucial management problem. Despite numerous publications dealing with efficient scheduling methods for vehicle routing, very few addressed the inherent stochastic and dynamic nature of travel times. In this paper, a vehicle routing problem with time-dependent travel times due to potential traffic congestion is considered. Th...

An estimation of the post mortem interval (PMI) is frequently touted as the Holy Grail of forensic pathology. During the first hours after death, PMI estimation is dependent on the rate of physical observable modifications including algor, rigor and livor mortis. However, these assessment methods are still largely unreliable and inaccurate. Alternatively, RNA has been put forward as a valuable ...

Linear system identification with noisy input/output is a critical problem in processing and control. Conventional techniques based on the mean squared-error criterion can at best provide a biased parameter estimate of the unknown system modeled. Recently, we proposed a new criter...

In this paper, a single-slope tunnel pipeline was analysed considering the effects of vertical earth pressure, horizontal soil pressure, inner pressure, thermal expansion force and pipeline-soil friction. The concept of stagnation point for the pipeline was proposed. Considering the deformation compatibility condition of the pipeline elbow, the push force of anchor blocks of a single-slope tunn...

1 I n t r o d u c t i o n The missing values problem is an old one for analysis tasks[8] [11]. The waste of da t a which can result f rom casewise deletion of missing values, obliges to propose alternatives approaches. A current one is to t ry to determine these values [9]. However, techniques to guess the missing values mus t be efficient, otherwise the complet ion introduces noise. Wi th the ...

E ngineers have long sought to design systems that understand and act upon spoken language. Extracting meaning from natural, unconstrained speech over the telephone is technically challenging, and quantifying semantic content is crucial for engineering and evaluating such systems. Traditional menu-driven speech recognition systems force users to learn the machine’s jargon, but many people are u...
