The score represents the actual data loss risk and is designed to enable the security operations team to initiate an appropriate investigative response. The risk score is evaluated by algorithms that combine knowledge about the content, baseline information ,and various observables and indicators regarding the source and the destination. These indicators are fused together using a framework cal...

The purpose of this study was to apply European Commission reference dose levels (EC RDLs) to routine CT examinations. The dosimetric quantities proposed in the European Guidelines (EG) for CT are weighted computed tomography dose index (CTDI(w)) for a single slice and dose-length product (DLP) for a complete examination. Patient-related data as well as technical parameters for brain, chest, ab...

Definition 1.1. Given a finite abelian group G written multiplicatively and elements b and g in G, the discrete logarithm problem (DLP) consists of finding an integer n such that bn = g, if such an n exists. The difficulty involved in computing the discrete logarithm varies with the choice of G. For example, in the additive group of integers modulo n, (Z/nZ)+, the problem can be solved efficien...

In this report, we present a prototype design of a quadrupole mass filter (QMF) with hyperbolic electrodes, fabricated at the University of Liverpool using digital light processing (DLP), a low-cost and lightweight 3D rapid prototyping (RP) technique. Experimental mass spectra are shown for H(2)(+), D(2)(+), and He(+) ions to provide proof of principle that the DLP mass filter is working as a m...

The main characteristic of today’s manufacturing environments is volatility. Under such a volatile environment some parameters like demand is not stable. To operate efficiently under such environments, the facilities must be adaptive to change production requirements. From a layout point of view, this situation requires the solution of the dynamic layout problem (DLP). Layout design has a signi...

Due to its high printing resolution and fast speed, digital light processing (DLP) has become one of the most widely used additive manufacturing technologies. In a typical DLP printing, resin is photocured from liquid into solid accompanied by large volume shrinkage, which often leads shape distortion printed structures. this study, we investigated shrinkage-induced DLP-printed parts conducting...

Today ontologies are heavily used in the sematic web. As they grow in size reasoning systems can’t work without secondary storage anymore. Thus database technology is required for storing and processing huge ontologies. In this paper we present an efficient technique for representing and reasoning with ontologies in databases. We also present some benchmarking results in comparison with previou...

Data Level Parallelism(DLP) can be exploited in order to improve the performance of processors for certain workload types. There are two main application fields that rely on DLP, multimedia and scientific computing. Most of the existing multimedia vector extensions use sub-word parallelism and wide data paths for processing independent, mainly integer, values in parallel. On the other hand, cla...

Dosimetry in kilovoltage cone beam computed tomography (CBCT) is a challenge due to the limitation of physical measurements. To address this, we used a Monte Carlo (MC) method to estimate the CT dose index (CTDI) and the dose length product (DLP) for a commercial CBCT system. As Dixon and Boone showed that CTDI concept can be applicable to both CBCT and conventional CT, we evaluated weighted CT...

OBJECTIVE Effective July 1, 2012, CT dose reporting became mandatory in California. We sought to assess radiologist compliance with this legislation and to determine areas for improvement. MATERIALS AND METHODS We retrospectively reviewed reports from all chest CT examinations performed at our institution from July 1, 2012, through June 30, 2013, for errors in documentation of volume CT dose ...
