Evaluating the power loss in power semiconductors is an important step in the process of research, development and design of a power electronics circuit topology. This paper presents a way of doing this via computer simulation. It is based on relatively simple component models and a fast simulation tool, but can quite precisely estimate the loss in power(More)
Prediction markets provide a promising approach for future event prediction. Most existing prediction market approaches are based on auction mechanisms. Despite their theoretical appeal and success in various application settings, these mechanisms suffer from several major drawbacks. First, opinions from experts and amateurs are treated equally. Second,(More)
The purpose of this study was to describe how an accomplished teacher taught second-grade students to design games that integrated movement and mathematics content. The participants were one physical education teacher; a classroom teacher, and an intact class of 20 second-grade students. Qualitative data were gathered through videotaping of all lessons,(More)
This column examines the cognitive load of prediction markets from four steps of user's decision process (that is, timing, pricing, revisiting, and benefit) and discusses how a prediction market mechanism could have a low cognitive load. In the column, the authors propose that fixed-odds betting can be used as a prediction market mechanism with carefully(More)
Prolonged hypotension during pheochromocytoma resection is a significant complication. We sought to investigate the predictors of prolonged hypotension in patients with pheochromocytoma undergoing laparoscopic adrenalectomy (LA). Patients with pheochromocytoma who underwent LA between 2012 and 2015 were surveyed. Patients were considered to have prolonged(More)
OBJECTIVE Primary cardiac amyloidosis (CA) is associated with poor prognosis. However, the noninvasive diagnostic tools are limited. The aim of the study is to assess the utility of combined indexes of electrocardiography (ECG) and echocardiography (ECHO) in the diagnosis of primary CA. METHODS A total of 20 consecutive patients (7 men, mean age 50 ± 12(More)
