A fundamental problem in software-based security is whether local security checks inserted into the code are sufficient to implement a global security property. We introduce a formalism based on a two-level lineartime temporal logic for specifying global security properties pertaining to the control-flow of the program, and illustrate its expressive power with a number of existing properties. W...

Numerical models are a key component of methodologies used to estimate tsunami risk, and model predictions are essential for the development of tsunami hazard assessments (THAs). By better understanding model bias and variability and, if possible, minimizing them, more reliable THAs will result. In this study, the authors compare run-up height, inundation lines, and flow-velocity field measurem...

The objective of this work was to investigate flow properties of powdered infant formula samples. Samples were purchased at a local pharmacy and differed in composition. Lactose free infant formula, gluten free infant formula and infant formulas containing dietary fibers and probiotics were tested and compared with a regular infant formula sample which did not contain any of these supplements. ...

By computing the probability distributions of the velocity difference between cars a time-delay r apart, the scaling properties of traffic flow can be analysed. These data display scaling behaviour thus confirming earlier results that have found 1/ /-noise in traffic flow. Furthermore, the applicability of the scaling analysis for describing the two-point statistics of traffic flow is demonstra...

In hot forming process, the workpiece undergoes plastic deformation at high temperature and the microstructure of the workpiece changes according to the plastic deformation. These changes affect the mechanical properties of workpiece. In order to optimize this process, both the plastic deformation of workpiece and its microstructural changes should be taken into consideration. Since material be...

This paper considers how explicit information flow properties can be expressed and verified in a traditional program logic, using preand postconditions. As concrete specification language for expressing these properties we use the specification language JML for Java. For this we propose a new classification of information flow properties, namely positive and negative properties, where the forme...

The purpose of this paper is to show that typical information flow policies can be enforced by enforcement mechanisms that work by monitoring a system execution at run time. the system execution represent an event sequence in the system. Our enforcement mechanism has extra structure. In this paper the extra structure become an emulator to work on a subsequence of the observed sequence in order ...

The circulatory transport system is responsible for oxygen and nutrient supply to all body tissues and removal of waste products. The discovery of the circulation of blood in the human body is related to William Harvey (1578–1657). The circulatory system consists of the heart—the pump that generates the pressure gradients needed to drive blood to all body tissues, the blood vessels—the delivery...
