How many times more for the papers that were presented at the "International Conference on Thermoelectrics" conference than "International Conference on Wireless Networks, Communications and Mobile Computing“ conference?
'International Conference on Thermoelectrics' AND 'International Conference on Wireless Networks, Communications and Mobile Computing' are the FullName of the conference; Papers refers to Paper.Id; Calculation = SUBTRACT(SUM(Paper.Id where FullName = 'International Conference on Thermoelectrics'), SUM(Paper.Id where FullName = 'International Conference on Wireless Networks, Communications and Mobile Computing'))
SELECT CAST(SUM(CASE WHEN T2.FullName = 'International Conference on Thermoelectrics' THEN 1 ELSE 0 END) AS REAL) / SUM(CASE WHEN T2.FullName = 'International Conference on Wireless Networks, Communications and Mobile Computing' THEN 1 ELSE 0 END) FROM Paper AS T1 INNER JOIN Conference AS T2 ON T1.ConferenceId = T2.Id
