Using Reclaimed Asphalt Pavement (RAP) in asphalt mixes has become a common practice in many countries as experience indicated that the recycling of asphalt pavements is very advantageous from different perspectives. Some of the advantages of utilizing RAP include conservation of asphalt and aggregate resources, conservation of energy, and reduction in life-cycle cost. In this study, the suitab...

The aim of this paper is to justify the use of constant mix investment strategies as an approximation for periodically rebalanced investment strategies. In Dhaene et al. (2005), general optimization problems are solved in a lognormal framework by deriving convex order bounds based on comonotonicity. The multi-period optimal portfolio selection problems discussed in Dhaene et al. (2005) are solv...

We evaluate the anonymity provided by two popular email mix implementations, Mixmaster and Reliable, and compare their effectiveness through the use of simulations which model the algorithms used by these mixing applications. In order to draw accurate conclusions about the operation of these mixes, we use as our input to these simulations actual traffic data obtained from a public anonymous rem...

In this study, we present an online music production tool that facilitates the capture of time-series audio and session data, including action history. This allows us to analyse sessions and infer production decisions based on actions made to the user interface. We conduct an experiment in which mix engineers were asked to use the system to perform a balance mix, then we provide observations ma...

We apply the information-theoretic anonymity metrics to continuous-time mixes, that individually delay messages instead of batching them. The anonymity of such mixes is measured based on their delay characteristics, and as an example the exponential mix (sg-mix) is analysed, simulated and shown to use the optimal strategy. We also describe a practical and powerful traffic analysis attack agains...

The possibilityof the use of unilamelbarphosphobipid vesicles (liposomes)as carriers of methotrexate (MTX) was exploredto overcomethe resistanceof solidtumors to the drug. Unilamellarvesicleswere preparedby sonic dispersion of phosphatidyicholine:cholesterol:stearyl amine (4:3:1) in an aqueoussolutioncontainingMTX. In MTX-resistant,cortisol-sensitiveP1798mouselymphosar coma cells in suspension,...

BACKGROUND AND OBJECTIVES Arteriovenous fistulas (AVFs) remain the preferred vascular access for hemodialysis patients. Dialysis facilities that fail to meet Centers for Medicare & Medicaid Services goals cite patient case-mix as a reason for low AVF prevalence. This study aimed to determine the magnitude of the variability in AVF usage across dialysis facilities and the extent to which patient...

We present a system for efficient meta-data indexed querying of XML documents. Given the diversity of the information available in XML, it is very useful to annotate XML data with a wide variety of meta-data, such as quality and security assessments. We address the meta-data indexing problem of efficiently identifying the XML elements along a location step in an XPath query, that satisfy meta-d...

Box MIX and MIXAL are available on the UCSD B6700; although, according to Ken Bowles, they are not currently being handled as fully supported products, and there may be some remaining bugs in the systems. However, MIX and MIXAL are available for network users, and Ken says they will be happy to receive notification of any errors found in the MIX and MIXAL and will attempt to get corrections mad...
