In project scheduling, many problems can arise when resource fluctuations are beyond acceptable limits. To overcome this, mathematical techniques have been developed for leveling resources. However, these produce a hard and inflexible approach in scheduling projects. The authors propose a simple resource leveling approach that can be used in scheduling projects with multi-mode execution activit...

This research proposes a preemptive fuzzy goal programming model for multi-objective multi-mode resource constrained project scheduling problem. The objectives of the problem are minimization of the total time and the total cost of the project. Objective in a multi-mode resource-constrained project scheduling problem is often a minimization of makespan. However, both time and cost should be con...

The coupled nonlinear Schrödinger equations (CNLS) which describe two linearly polarized modes interaction (with taken into account the polarization modes interaction) in the Kerr medium is derived. We take first two modes for cylindrical fiber which are also known as HE11 and TE01 modes which have different propagation constant. This approach bases on projection to orthogonal function basis (B...

Introduction: In previous work, we introduced the concept of the multi-mode intravascular MRI coil [1,2] which consists of a single active device that is connected to the external system via a single coaxial cable and performs three functions: 1) active tip tracking, 2) imaging, and 3) inductively-coupled wireless marker. The purpose of such a multi-functional coil is to enable single insertion...

Tapered MMI devices are proposed. It is demonstrated that the proposed single-stage MMI device's output power efficiency can be 55% higher than a conventional adiabatic taper by partially capturing the 2nd order mode power. ©2010 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (130.2790) Guided waves

With the rapid development of road traffic, real-time vehicle counting is very important in construction intelligent transportation systems (ITSs). Compared with traditional technologies, video-based method for shows great importance and huge advantages its low cost, high efficiency, flexibility. However, many methods find difficulty balancing accuracy complexity algorithm. For example, compare...

In the present study, an experimental investigation was performed to characterize the vortex induced vibration (VIV) of a flexible cable in an oncoming shear flow. The VIV tests were conducted in a wind tunnel with a flexible cable model. It was found that, under different oncoming velocity profiles, the cable model behaved in single-mode and multi-mode VIVs. The displacement amplitudes of the ...
