The problem of estimation of a proportion of a sensitive character using a randomization device in survey sampling is well known since Warner (1965). A detailed review and applications of such techniques can be found in Fox and Tracy (1986). Following Gjestvang and Singh (2006), let and be two known positive real numbers. Gjestvang and Singh (2009) considered a new additive model in which each ...

Trick: Deal 27 cards, face up onto a table in three columns with 9 cards in each. Ask your victim to choose a card but not to tell you what it is. Three times, ask in which column the card lies, and each time, collect the cards, putting the selected column between the cards in the other two columns, leaving the columns in order, and then deal the cards again by rows to make the next set of colu...

This paper describes a biometric method for user authentication on smart cards. Smart cards are chip cards with the ability for data processing directly on the card. They are not only usable for storing biometric reference data, but biometric user authentication methods can also be performed on card in order to protect security-relevant functions or data on the cards. The biometric data under c...

Class Responsibility Collaborator (CRC) Cards can be used in developing Object-Oriented models. They provide a simple and an easy to use way to explore objects in the development of a system. However, different problems might arise while adopting current CRC-Cards in identifying the system objects. In this paper, we discuss the main problems with current CRC-Cards. As a solution, we propose a n...

UNLABELLED Mycoplasma pneumoniae synthesizes a novel human surfactant protein A (SP-A)-binding cytotoxin, designated community-acquired respiratory distress syndrome (CARDS) toxin, that exhibits ADP-ribosylating and vacuolating activities in mammalian cells and is directly linked to a range of acute and chronic airway diseases, including asthma. In our attempt to detect additional CARDS toxin-b...

Despite achieving a significant cost reduction over the past two decades, the absolute cost of food subsidies in Egypt is still high relative to the benefits received by the poor. There is scope for better targeting these food subsidies, in particular for targeting cooking oil and sugar ration cards, both because reforms in this area are perceived to be far less politically sensitive than adjus...

The “five-card trick” invented by Boer allows Alice and Bob to securely compute the AND function of their secret inputs using five cards—three black cards and two red cards—with identical backs. This paper shows that such a secure computation can be done with only four cards. Specifically, we give a protocol to achieve a secure computation of AND using only four cards—two black and two red. Our...
