Abstract: Provided is a method, system, and a computer-readable recording medium for providing a personalized recommendation of products. The method may include extracting product recommendations corresponding to a prescribed recommendation time period using two or more purchase cycle algorithms, the purchase cycle algorithms configured to calculate purchase cycles of products for a customer. The method may further include performing performance evaluation, using a processor, with respect to the product recommendations extracted using each of the purchase cycle algorithms, and recommending to the customer the product recommendation extracted from the purchase cycle algorithm having a highest ranking based on the performance evaluation.

Abstract: Disclosed herein is an air duct assembly for vehicles which reduces noise generated by the flow of intake air which flows along a path of the air duct provided in a vehicle and is fed to an engine. The air duct reduces the noise of a low frequency range in initial engine start operation, and in addition, the noise of a whole frequency range, thus allowing a vehicle to be traveled while providing the environment having minimum noise to a driver and passenger riding in the vehicle. Therefore, it is not necessary to install an additional resonator.

Abstract: The vehicle canister comprising: the first chamber filled with the active carbon and funneled with the tank port, where the evaporating gas is infused through and the second chamber filled with the active carbon and funneled with the atmosphere port and neighboring the first chamber via the isolation wall. Also, it involves the vehicle canister installed in the canister housing which has the absorption and desorption improver to improve the absorption and desorption efficiency with heat conduction with temperature change of the active carbon occurred during the absorption and desorption of evaporation gas infused into the canister housing. The absorption and desorption improver is composed with the first and the second absorption and desorption improver.
