Phase Change Memory (PCM) is a new non-volatile memory technology that is comparable to traditional DRAM with regard to read latency, and markedly superior with regard to storage density and idle power consumption. Due to these desirable characteristics, PCM is expected to play a significant role in the next generation of computing systems. However, it also has limitations in the form of expens...

Agents in an open system interact with each other based on (typically, published) protocols. An agent may, however, deviate from the protocol because of its internal policies. Such deviations pose certain challenges: (1) the agent might no longer be conformant with the protocol—how do we determine if the agent is conformant? (2) the agent may no longer be able to interoperate with other agents—...

In the paper proposed secure architecture is FIPA compliant in the sense that every common FIPA compliant agent should be able to interact with agents having this extended architecture even not knowing the security mechanisms. On the other hand, agents demanding for security can, of course, refuse plain, non secured communication with non authenticated agents, etc. The security mechanisms can u...

This paper deals with planning assembly processes for a manipulator using numerical simulations. The dynamical model of the robot includes elasticity, damping , friction and backlash in the joints. In addition several models of typical mounting processes are used to calculate the forces and torques acting on the gripper during the assembly task. In this paper we speciically present the modellin...

This thesis presents the findings of exploratory research in low-cost compliant robotics. The most heavily leveraged trade-off is that of mechanical precision for computational power, with the hope that the price of future computation will continue to fall exponentially while the expected price of precision mechanical parts will remain relatively constant. The most novel contribution of this re...

Accurate timestamps on both the sender and the receiver side are crucial for one-way delay (OWD) measurements. Traditionally, the methods of (i) peering with NTP servers, and (ii) connecting to a time source directly, have been used to maintain the accuracy of a measurement system clock. However, it has became clear that such methods suffer from errors to different extents. In this paper, we in...

Anthrax Anthrax is a zoonotic disease caused by the spore-forming bacterium Bacillus anthracis. The term anthrax is derived from the Greek word for coal, anthrakis, because of the black skin lesions characteristic of the disease. A disease that appears to have been anthrax was described in the biblical book of Exodus as the fifth plague in about 1490 BCE. Descriptions of anthrax affecting both ...

We present standards-compliant visible watermarking schemes for digital images and video in DCT-based compressed formats. The watermarked data is in the same compressed format as the original and can be viewed with standard tools and applications. Moreover, for most of the schemes presented, the watermarked data has exactly the same compressed size as the original. The watermark can be inserted...

The value of business rules in business process modeling has been recognized by several authors: if the knowledge about implicitly present policies and regulations is made explicitly traceable as business rules we can enhance the flexibility of computer-supported business processes. Yet to date it is not fully clear how business rules can be used to model compliant business process models. In t...
