This paper investigates the performance of an overloaded multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system with and without antenna selection. In the overloaded MIMO-OFDM system, even if only a small amount of feedback is available, performance can be improved by selecting the transmit antennas. Thus, this paper compares the performance of an overloa...

In this paper, we extend the results on the modularity of con uence and termination of single-sorted TRSs[3][6][7] to order-sorted ones. Order-sorted TRSs build a good framework for handling overloaded functions and subtypes. For proving modularity of completeness of ordersorted TRSs, we rst transform a TRS with overloaded functions to a non-overloaded one, and then we demonstrate that our tran...

A naı̈ve translation of recursive cases in type class instances will give code that allocates a new dictionary and copies the data from the input dictionary to the new dictionary for the recursive call. This record creation allocates memory and leads to bad performance for a conceptually simple and rather common operation, for example equality between lists. We present a positive supercompilatio...

Orthogonal drawings are widely used for graph visualization due to their high clarity of representation. In this paper we present a technique called Overloaded Orthogonal Drawing. We first place the vertices on grid points following a relaxed version of dominance drawing, called weak dominance condition. Edge routing is implied automatically by the vertex coordinates. In order to simplify these...

mechanism and factors influencing on creep behavior of clay soil have not been understood yet due to its complex structure. in this paper, to investigate the affecting parameters on the creep behavior of the clay soils such as stress level, over consolidated pressure and water pressure, odeometr test are performed in states of single stage, stepwise and overloaded-unloaded and the creep mechani...

Because of today's increased traffic volume and sophisticated attacks, implementing a network intrusion detection/prevention system (NIDS/NIPS) with a single workstation has been challenging. In this paper, we propose Brownie, a system for improving performance by coordinating configurations of alreadyexisting, independently-managed NIDSs in an organization. Instead of installing one expensive ...
