Communication is a transaction in which man invents and assigns meanings to achieve its objectives. In this context, psychological theories of communication emphasize different components of human communication, including attitudes, intentions and conditions required for effective communication. In psychological models of communication, the source is influenced by its communicational abilities,...

Medication errors can cause substantial harm to patients. Automated patient medication systems with RFID technology is purposely used to reduce the medication error, to improve the patient safety, to provide personalized patient medication and identification and also to provide counterfeit protection to the patients. In order to enhance medication safety for patients we propose a new dynamic ID...

This paper proposes a new scheme for partially blind signature based on the difficulty in solving the discrete logarithm problem. Under the assumption of the generic model, random oracle model, and intractable ROS-problem, this paper formally proves that the proposed scheme is secure against one-more signature forgery under the adaptively parallel attack. Previous schemes using two signing equa...

The Cyberspace Visualization Project – CVP – explores techniques for interactive 3D visualizations of the web, supporting orientation and basic communicational features1. Users can represent themselves within these visualizations and thus become aware of each other. This could be a base for a more direct communication on the web. Current software components are introduced and a placement algori...

Original scientific article High performance routers are fundamental building blocks of the system wide interconnection networks for high performance computing systems. Through collective interaction they provide reliable communication between the computing nodes and manage the communicational dataflow. The development process of specialized router architecture has high complexity and it requir...

The Residue Number System (RNS) is a non-weighted system that is very efficient in digital signal processing and communicational applications. The previous proposed methods for the residue to binary (R/B) conversions are based on the Chinese Reminder Theorem (CRT) or Mixed Radix Conversion (MRC). These theorems are difficult to implement. In this paper, we present a new highspeed ROM-less resid...

We study client-to-client password-authenticated key exchange (C2C-PAKE) enabling two clients in different realms to agree on a common session key using different passwords. Byun et al. first presented C2C-PAKE schemes under the cross-realm setting. However, the schemes were not formally treated, and subsequently found to be flawed. In addition, in the schemes, there are still rooms for improve...

Resource Constrained Devices (RCD) in general construct the pervasive computing environment which are equipped with too limited resources to deploy privacy preserving data mining applications. This paper proposes a communication efficient and perturbation based privacy preserving association rule mining (ARM) algorithm for this ubiquitous computing environment. Existing cryptography based priva...

The expectations of emotional displays play an important role in human-human and human-robot interaction in order to achieve a constructive interaction. However, as we argue in this position paper, current state-of-the-art social robotic models of emotion still neglect the communicational aspects of emotions. Based on different psychological models of emotion, we argue that an intra-personal ac...
