We describe a new trap-door (and PKC) proposal. The proposal is “multivariate quadratic” (relies on the hardness of solving systems of quadratic equations); it is also code-based, and uses the code-scrambling technique of McEliece (1978). However, in the new proposal, the errorcorrecting code is not revealed in the public key, which protects against the leading attacks on McEliece’s method.

In most cases, therapy is addressed as an indoor, verbal, and cognitive activity, with the relationship between therapist and client at its center (McLeod, 2003). This article presents an alternative approach to therapy, conducted in creative ways in nature, addressing the environment not merely as a setting but as a partner in the process.

In the Monty Hall Dilemma (MHD), three doors are presented with a prize behind one and participants are instructed to choose a door. One of the unchosen doors not containing the prize is revealed, following which the participant can choose to stay with their chosen door or switch to the other one. The optimal strategy is to switch. Herbranson and Schroeder (2010) found that humans performed poo...

AIM As door handles represent a transmission route for viruses and micro-organisms, a door opening and closing mechanism should be developed without manual operation. METHOD To solve the problem, a device for opening the door with the help of a foot pedal was built into the door leaf.

Direct selling is exhibiting substantial growth in sales revenues and number of salespeople involved. Also the acceptation of consumers is growing. During the last decade direct selling organizations (DSOs) are using the Internet more and more, either to communicate with the salespersons, either to promote the products and the business to the consumers. This research is aiming to contribute to ...

BACKGROUND Little is known about the components of door-to-balloon time among patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention. We assessed the role of time from hospital arrival to ST-segment elevation myocardial infarction diagnosis (door-to-activation time) on door-to-balloon time in contemporary practice and evaluated factors tha...

In this research we try and implement communication system using the metaphor of a door on the World Wide Web (WWW) as a media for novel types of informal communications. We call those informal communications through a door ”on-door communications.” As an on-door communication system, we have designed and implemented a system for a chat at a net door. One has a door page on WWW and a chat syste...
