-In this paper, multi-objective optimal placement (MOOP) of multi-type flexible AC transmission systems (FACTS) devices for Thailand power system is proposed. Four types of FACTS devices are used: thyristor-controlled series capacitor (TCSC), thyristor-controlled phase shifter (TCPS), unified power flow controller (UPFC), and static var compensator (SVC). The problem is decomposed into the opti...

Falls are a major problem in the elderly population, but few communications address the influence of anesthesia on balance control. This study reports how a general balanced anesthesia (GBA) and a spinal anesthesia (SA) affect balance control in the elderly. We divided into three groups, according to electronystagmography findings and type of anesthesia, 21 men older than 65 years (mean age, 72...

We prove a dichotomy theorem for the rank of the uniformly generated (i.e. expressible in First-Order (FO) Logic) propositional tautologies in both the Lovász-Schrijver (LS) and Sherali-Adams (SA) proof systems. More precisely, we first show that the propositional translations of FO formulae that are universally true, i.e. hold in all finite and infinite models, have LS proofs whose rank is con...

Sustainability science (SS) has emerged to foster inter- and transdisciplinary research practices the creation of new, robust, actionable knowledge for navigating sustainability transitions. However, whether paradigm emerging SS permeated relevant body integrate with subfield assessment (SA) is an open question. Aiming investigate enhance interdisciplinary communication in theory practice, we c...

This article reviews the current techniques of surface electromyography (SEMG) assessment. Discussed are static, dynamic, and combination assessment techniques and the rational for their use.
