Diversity Multiplexing Trade-off in MIMO Systems

This report describes my method of increasing the capacity of any wireless network through the application of MIMO technology. The Shannon capacity of wireless networks has been calculated in different instances by MATLAB. Using Simulink, the various parameters of a wireless Rayleigh Multipath fading channel are calculated. This is done in order to experimentally prove the advantages of a MIMO ...

An Analysis of International Outsourcing in Iran-China Trade Relations

Iran-China relations are deeply rooted in history and have been enhanced recently with bilateral cooperation in the areas of energy, arms sales, trade, political cooperation and cultural ties. The objective of this paper is to analyze the role of international outsourcing in form of trading intermediate products on bilateral trade relations between Iran and China. As an empirical work, we h...

Evaluation Metrics Trade-off for Recommendation Systems

Following the famous Netflix Prize competition, accuracy metrics (such as RMSE) became a de facto standard in the community to evaluate and compare performance of recommendation algorithms. However, it has been shown, that accuracy is not the best way to quantify the quality of recommendations, especially in the context of predicting online performance from offline evaluations [1]. Thus, it mak...

ISM Seminar Trade-off Balancing of Scheduling in Serial Systems

min(∑Cj), are two fundamental objectives of scheduling in serial systems, where a serial system consists of a number of stages or machines, and operations must be done sequentially from the first operation to the last. An m-machine flow line for production scheduling in manufacturing systems and a 3-stage perioperative (periop) process for operating room (OR) scheduling in healthcare systems ar...
