This research proposes a new similar information recommendation system focusing on social bookmarking, which organises bookmarks by using tags. Since social bookmarking targets a wide variety of genres of web pages, this research handles the problem where the standard collaborative filtering method cannot offer recommendations with a better level of precision. This paper improves the collaborative filtering algorithm for users of social bookmark services. A user's bookmarks are placed on his/her own classifying space made of tags. These bookmarks are transformed into a degree of similarity for recommendations. The degree is used to compare the personal classifying space with another's space. Comparison with previous studies confirms the superiority of the method based on space classification, in particular, where the cos distance with the distribution weight added is used as similarity between items. This proposed method shows a significant superiority. Copyright © 2013 Inderscience Enterprises Ltd. Source

In a magnetic head cleaning mechanism applicable to a magnetic tape apparatus employing a threading scheme, a cleaning brush is driven in a small space; and a magnetic tape apparatus includes the magnetic head cleaning mechanism. The mechanism includes a threading arm to engage a leader block with a leader pin to draw the block engaged with the pin, a magnetic head to conduct data reading and writing operation on a magnetic tape, a rotably supported brush link arm including a brush at a tip end thereof, and a cam gear disposed on the side of the magnetic head relative to a threader track as a transport route of the magnetic tape. Ordinarily, the arm is on the side of the magnetic head relative to the threader track. When the leader block is moved to a position near the leader pin, the arm rotates with rotation of the cam gear to bring the brush into contact with the magnetic head on the threader track.

A long time has now elapsed since environmental concerns became an important issue of the business domain. Power saving for the PCs that occupy a significant share among office IT equipment still remains one of the most important considerations. In 2010, NEC set a target of halving its power consumption from the 2005 level. Since then, the corporation has been tackling power saving of PCs and the reduction of CO 2 emissions from various viewpoints, including those from a hardware perspective such as redesigning circuitry as well as from a software perspective such as for incorporation of the "ECO mode" with which the power setting can be changed by a one-touch operation. This paper introduces the measures being applied by NEC in order to save the electrical energy consumed by PCs in the business environment. Source
