Web applications require access to the file-system for many different tasks. When analyzing the security of a web application, security analysts should thus consider the impact that file-system operations have on the security of the whole application. Moreover, the analysis should take into consideration how file-system vulnerabilities might interact with(More)
This article describes the prenatal sonographic diagnosis of a rare case of intracranial immature teratoma in a fetus at the 35th week of gestation which looked normal at previous examinations. At sonography a markedly enlarged fetal head containing a complex irregular mass and hydrocephalus was detected. Color Doppler examination of the mass showed intense(More)
We present a formal approach for the analysis of attacks that exploit SQLi to violate security properties of web applications. We give a formal representation of web applications and databases, and show that our formalization effectively exploits SQLi attacks. We implemented our approach in a prototype tool called SQLfast and we show its efficiency on four(More)
AIMS To evaluate the specificity of ultrasound in identifying fetal brain neoplasms and its accuracy in the diagnosis of the tumor's histological type. METHODS A retrospective evaluation of 7 cases of fetal brain tumors occurred at our unit in the period between January 92 and June 98 has been performed. All prenatal ultrasonographic diagnoses were(More)
In a class of games known as Stackelberg games, one agent (the leader) must commit to a strategy that can be observed by the other agent (the follower or adversary) before the adversary chooses its own strategy. We consider Bayesian Stackelberg games, in which the leader is uncertain about the types of adversary it may face. This paper presents a possible(More)
The ultrasonographic imaging of a fetus affected by 3-M syndrome is described. This is a primordial dwarfism with low birthweight, short stature, facial dysmorphism and normal mental development. The biparietal diameter and head circumference were in accordance with the gestational age at 18 weeks. The femur and tibia lengths were on the fifth centile and(More)
