Resource provisioning remains as one of the chal-lenging research problems in cloud computing, more importantly when considered together with service reliability. Fault-tolerance techniques such as fault-recovery is one of the techniques that can be employed to improve on service reliability. Technically, fault-recovery has obvious impact on service performance. Such impact… Read full abstract & cite →

Modeling and Solving the Open-End Bin Packing Problem

Author 1: Maiza Mohamed Author 2: Tebbal Mohamed Author 3: Rabia Billal

In the Open-End Bin Packing Problem a set of items with varying weights must be packed into bins of uniform weight limit such that the capacity of the bin can be exceeded only by the last packed item, known as the overflow item. The objective is to minimize the number… Read full abstract & cite →

Performance Comparison between MAI and Noise Constrained LMS Algorithm for MIMO CDMA DFE and Linear Equalizers

Author 1: Khalid Mahmood

This paper presents a performance comparison between a constrained least mean squared algorithm for MIMO CDMA decision feedback equalizer and linear equalizer. Both algorithms are constrained on the length of spreading sequence, number of users, variance of multiple access interference as well as additive white Gaussian noise (new constraint). An… Read full abstract & cite →
