Crustaceans is one of the most common causes of food allergies. Its persistency is life-threatening therefore, method to detect the presence of crustacean constituent in food products would be indispensable to ensure the safety. We have developed a simple and rapid method to detect the presence of crustacean residues in food products through the allergenic Pen gene. Detection method was based o...

A novel approach for classification and dating of the black gel pen ink entries on document was developed based on ion-pairing high-performance liquid chromatography (IP-HPLC). Ninety-three black gel pens were collected and divided into two groups, dye-based and pigment-based, by preliminary solubility test. The chromatographic conditions for separation of the dye-based black gel pen inks were ...

We present a technique for segmenting pen strokes into lines and arcs. The technique uses pen speed information to help infer the segmentation intended by the drawer. To begin, a set of candidate segment points is identified. This set includes speed minima below a threshold computed from the average pen speed. It also includes curvature maxima at which the pen speed is again below a threshold. ...

SUMMARY Continuous pen pressure can be used to operate multi-state widgets such as menus in pen based user interfaces. The number of levels into which the pen pressure space is divided determines the number of states in the multi-state widgets. To increase the optimal number of divisions of the pen pressure space and achieve greater pen pressure usabil-ity, we propose a new discretization metho...
