Much current research is undertaken into combining classifiers to increase the classification accuracy. We show, by means of an enumerative example, how combining classifiers can lead to much greater or lesser accuracy than each individual classifier. Measures of diversity among the classifiers taken from the literature are shown to only exhibit a weak relationship with majority vote accuracy. ...

In CDMA communication systems, all the subscribers share the common channel. The limitation factor on the system’s capacity is not the bandwidth, but multiuser interference and the near far problem. This paper models CDMA system from the perspective of mobile radio channels corrupted by additive white noise generated by multipath and multiple access interferences. The system’s receiver is assis...

Peer-to-peer multihop relaying in TDMA networks can provide significant gains in network throughput, particularly when relaying is combined with relaying diversity schemes such as multihop selection combining or multihop maximal ratio combining. This paper presents a novel diversity-aware routing algorithm adapted from the Bellman-Ford algorithm which results in significant throughput gains and...

Background and Objectives: Efficient cost management in hospitals’ pharmaceutical inventories have the potential to remarkably contribute to optimization of overall hospital expenditures. To this end, reliable forecasting models for accurate prediction of future pharmaceutical demands are instrumental. While the linear methods are frequently used for forecasting purposes chiefly due to their si...

Inspired by nature, scientists have harnessed the natural protein translation machinery to produce intricate and precise protein‐based polymers (PBPs)—composed of amino acid monomers assembled on nano‐to‐macro scale—for drug gene delivery, sense environment, valuable molecules, grow cells tissues. Beyond chemical repertoire acids, conjugation chemically diverse molecules recombinant PBPs can in...

Exact integral expressions are derived for calculating the symbol-error rate (SER) of multilevel quadrature amplitude modulation (MQAM) in conjunction with L-fold antenna diversity on arbitrary Nakagami fading channel. Both maximal-ratio combining (MRC) (in independent and correlated fading) and equal-gain combining (EGC) predetection (in independent fading) diversity techniques have been consi...

Type-based receivers assume no a priori channel model, and were previously shown to be e ective in direct-sequence spread spectrum communications. In this paper, we investigate the macro-diversity combining of multiple type-based receivers in single-mobile-user reception (BPSK). We present a method for the exact calculation of the bit error rate of type-based receivers in this scenario. Maximal...
