| This paper describes a genetic algorithm using a Pareto partitioning method for multiobjective owshop scheduling. The purpose of the proposed method is to generate a set of non-dominated solutions that is properly distributed in the neighborhood of the trade-o surface. Simulation results show that the GA using the Pareto partitioning method has good performances better than the traditional GA...

Applying spatial mode switching in channel adaptive MIMO systems promises to achieve high spectral efficiencies in practical system setups. Several studies have pointed out significant performance gains obtained in realistically modeled channel scenarios. We have conducted channel measurements with the Berlin LTE-Advanced Testbed operated in the city center of Berlin and used these for the perf...

Human actions often involve complex interactions across several inter-related objects in the scene. However, existing approaches to fine-grained video understanding or visual relationship detection often rely on single object representation or pairwise object relationships. Furthermore, learning interactions across multiple objects in hundreds of frames for video is computationally infeasible a...

As the improvement of computing power, texting mining becomes more focused than before. In order to realize the literature productivity of such territory, we analyze the literatures on SSCI database with subjects as “Text Mining”. Applied the methodology of bibliometrics, we found several outcomes in this research. First, the distribution of frequency indexes of author’s productivity fulfills L...

Nowadays, customers request more variation in a company’s product assortment leading to an increased amount of parts moving around on the shop floor. To cope with this tendency, a kitting process can be implemented. As it gathers the necessary parts into a container prior to assembly, kitting enables a more cost-efficient and qualitative production. However, the performance of this preparation ...

In this paper an exact and complete analysis of average design complexities of Lloyd-Max's scalar quantizers, scalar compandors and scalar quantizers designed using the hybrid model is carried out. The average design complexity depends on arithmetic complexity, memory complexity and implementation complexity. It is demonstrated that for a fixed number of quantizaton levels N, scalar compandors ...

A decision support system for the optimal deployment of drifting acoustic sensor networks for cooperative track detection in underwater surveillance applications is proposed and tested on a simulated scenario. The system integrates sea water current forecasts, sensor range models and simple drifting buoy kinematic models to predict sensor positions and temporal network performance. A multi-obje...

The present paper focuses on the application of the base station cooperation (BSC) technique in fractional frequency reuse (FFR) networks. Fractional frequency reuse is considered to be a promising scheme for avoiding the inter-cell interference problem in OFDMA cellular systems, such as WiMAX, in which the edge mobile stations (MSs) of adjacent cells use different subchannels for separate tran...

The aim of this paper is to share novel paradigm of channel estimation for orthogonal frequency division multiplexing (OFDM) systems. OFDM is used to improve spectral efficiency and spatial diversity in wireless communications systems. This paper provides a review of channel estimation techniques (blind and pilot-aided) and its performance on data-aided channel. After comparison with known tech...

Virtual machine placement is a process of mapping virtual machines to physical machines. The optimal placement is important for improving power efficiency and resource utilization in a cloud computing environment. In this paper, we propose a multi-objective ant colony system algorithm for the virtual machine placement problem. The goal is to efficiently obtain a set of non-dominated solutions (...
