Abstract: A baseline predictive maintenance method for a target device (TD) and a computer program product thereof are provided. Fresh samples which are generated when the target device produces workpieces just after maintenance are collected, and a new workpiece sample which is generated when the target device produces a new workpiece is collected. A plurality of modeling samples are used to build a TD baseline model in accordance with a conjecturing algorithm, wherein the modeling samples include the new workpiece sample and the fresh samples. A TD healthy baseline value for the new workpiece is computed by the TD baseline model, and a device health index (DHI), a baseline error index (BEI) and baseline individual similarity indices (ISIB) are computed, thereby achieving the goals of fault detection and classification (FDC) and predictive maintenance (PdM).

Abstract: A non-intrusive access control method. First, identification of a tag and real-time circumstance information both related to a detection area are acquired. Next, whether the tag is permitted is determined based on circumstance identification corresponding to the detection area, the tag and the real-time circumstance information.

Abstract: A document processing method executed in an electronic device. First, three kinds of data are acquired, display capability information and preference information related to a display of a mobile communication device, and a document including a plurality of questions. Next, the style in which the document is displayed on the display of the mobile communication device is determined based on the display capability information, the preference information, and the document.

Abstract: A dynamic delegation method. First, a set of delegation policies are provided as general rules for limiting delegation. Next, two kinds of data are received, including a delegation condition and a delegation approval submitted by a grantor for vesting authority of the grantor's role to a grantee, wherein the grantor's role is granted the authority to access a set of data. Next, consequent authority actually vested to the grantee is determined based on the delegation approval, the delegation condition and the delegation policies.

Abstract: A non-intrusive access control method. First, identification of a tag and real-time circumstance information both related to a detection area are acquired. Next, whether the tag is permitted is determined based on circumstance identification corresponding to the detection area, the tag and the real-time circumstance information.
