Multi-class classifier training using traditional meta-algorithms such as the popular One-vs-One (OvO) method may not always work well under cost-sensitive setups. Also, during inference, OvO becomes computationally challenging for higher class counts K O(K^2) is its time complexity. In this paper, we present Opt-OvO, an optimized (resource-friendly) version of algorithm to enable high-performa...

In this paper, we introduce a new algebraic structure, called a UP-algebra (UP means the University of Phayao) and a concept of UP-ideals, UP-subalgebras, congruences and UP-homomorphisms in UP-algebras, and investigated some related properties of them. We also describe connections between UP-ideals, UP-subalgebras, congruences and UP-homomorphisms, and show that the notion of UP-algebras is a ...

This work shows the results obtained from studying influence of equivalent circuit resistances on three-phase induction motors. The stator resistance, rotor and iron losses resistance affect different motor operating variables (output power, current, speed, power factor, starting ratios, maximum torque). These influences have been quantified, paying particular attention to affected their impact...

CO2 can be converted to the more reactive species, CO and O, by non-thermal plasmas (NTPs) even in atmospheres containing significant quantities of O2. The conversion was 15–21%, when O2 concentration range 0–20% (remainder CO2). At 20% began decline, falling ~10% at 50% These conversions would require a few thousand K conventional “thermal” chemistry, absence catalyst, but here they were achie...
