Xylan extracts from southern US hardwood were used for the adsorption of both hardwood and softwood pulp. Pulp beatability and physical strength properties were determined and compared with those of the conventional Kraft pulp and pre-extracted modified Kraft pulp. The results indicated that hemicelluloses adsorption greatly improved pulp beatability. Compared to conventional Kraft pulp, a sign...

The design of a microcontroller based pacemaker tester is presented in this paper. Both invasive and noninvasive (transthoracic) pacemakers can be tested using this device. Two test loads are provided; a 500 ohms load for testing invasive pacemakers and a 50 ohms load for testing non-invasive pacemakers. A two line LCD display is used to indicate the test parameters, test results and the test i...

We consider the tasks of testing and spot-checking for data streams. These testers and spotcheckers are potentially useful in real-time or near real-time applications that process huge data sets. Crucial aspects of the computational model include the space complexity of the testers and spot-checkers (ideally much lower than the size of the input stream) and the number of passes that the tester ...

Dehydrated citrus pulp and citrus pulp-protein supplements were evaluated as potential supplements for a preconditioning program. The supplements compared were no supplement, citrus pulp alone, citrus pulp with urea, and citrus pulp with added UIP. Supplemented cattle produced greater gains than unsupplemented cattle. Citrus pulp with added UIP produced the greatest ADG (0.95 lb/hd/d) whereas c...

This paper presents an extensible and reusable framework which addresses the problem of video quality assessment over IP networks. The proposed tool (referred to as Video-Tester) supports raw uncompressed video encoding and decoding. It also includes different video over IP transmission methods (i.e.: RTP over UDP unicast and multicast, as well as RTP over TCP). In addition, it is furnished wit...

We have developed an improved subtractive hybridization method that provides a fast, simple and reliable isolation of desired different sequences from two compared DNA libraries, one of which contains all unwanted homologues (subtracter) and another contains certain desired heterologues (tester). The DNA library can be made from either mRNA or genomic DNA. An excess amount of modified subtracte...

Thermophilic mannanase from the Bacillus sp. MG-33 was applied on wheat straw-rich-soda pulp to evaluate its bleaching potential. Optimum conditions for bio-bleaching of pulp were found as, mannanase 3Ug -1 of pulp at pH 6.5 and temperature 65oC that enhanced the brightness by 30% and reduced the kappa number by 20% within 2h. Tear index (1.1, points) and burst index (0.02, points) were also im...

A novel test vector compression/decompression technique is proposed for reducing the amount of test data that must be stored on a tester and transferred to each core when testing a core-based design. A small amount of on-chip circuitry is used to reduce both the test storage and test time required for testing a core-based design. The fully specified test vectors provided by the core vendor are ...

This paper presents a strategy for testing future generations of wafer-level packaged logic devices that have nanoscale I/O structures. The strategy assumes that the devices incorporate built-in self test (BIST) features so that only a subset of the functional I/O needs to be directly accessed during testing. A miniature tester is described that provides test control, pattern sequencing, and cr...

Students in VLSI design courses find the opportunity to fabricate their chip designs very exciting and motivational. However, testing the chips after fabrication can be a hassle for both students and faculty. In collaboration with Sun Microsystems Laboratories, we have developed a functional chip tester that applies test vectors at low speed to check logical operation. The tester supports packa...
