Decision support systems that help physicians are becoming very important part of medical decision making. They are based on different models and the best of them are providing an explanation together with an accurate, reliable and quick response. One of the most viable among decision-making models is the concept of decision trees, already successfully used for many medical decision making purposes. Although effective and reliable, the traditional decision tree construction approach still contains several deficiencies. Therefore we decided to develop and compare several decision supporting models, each of them built with different discretization of attributes and decision classes. For the construction of decision trees we used MtDeciT, in our laboratory developed tool for building decision trees using the classical induction method. All solutions were evolved for determining the influence of basic properties of child and his/her parents to length of successful breastfeeding. A comparison between developed models and obtained results has shown that the way of discretization obviously plays a great role in the reliable and accurate real-world medical decision making.

computer-managed instruction (CMI) has been used in nursing education since the late 1960s. It is because of its accessibility and self-paced format that CMI is very well suited both to students and practising nurses, as learning can take place at the learner's own pace and in his or her own time. In addition CMI also supports continuing education and distant learning. The aim of this paper is to present CArE - a software package for computer Aided Nurse Education and in particular, for teaching the basics of the nursing care process. This package has been developed as a result of the Phare TEMPUS project called NICE (Nursing Informatics and computer Aided Education) [14] [15].

Investigates a robust adaptive control design for a flexible two-link system considering joint angle control in the presence of system uncertainties. The system uncertainties are treated as unknown bounded continuous functions of the states. A Gaussian network is used to map the uncertainties in the MIMO system. A convergent stable learning algorithm is developed for the control design. Simulations show the effectiveness of the proposed learning control strategy.

Cache coherence protocols are important for operating a shared-memory multiprocessor system with efficiency and correctness. Cache coherence protocols have become increasingly complex because physical memory is logically distributed, so that it is difficult for programmers to understand the view of logical shared-memory systems. Since random testing and simulations are not enough to validate the correctness of these protocols, it is necessary to develop efficient and reliable verification methods. Through the use of the Symbolic State Model (SSM) of Fong Pong (1995), we verified a directory-based protocol called the RACE (Remote-Access Cache coherence Enforcement) protocol. The protocol is verified for any system size, without state-space explosion.

A Vector Unit (VU) for the high performance 3D graphics computing has been developed. Four fMAC (floating-point Multiply-Accumulate) units which execute multiply-add operation with one throughput, one fDIV (floating-point Divide) unit which executes division and square root operations with 6 cycles at 300 MHz and 128 bits × 32 words fReg (floating-point register file) are implemented. This architecture delivers a peak performance of 2.44 GFLOPS at 300MHz.

This paper extends the useful concept of open systems proposed by W.S. Liu, et al. (1997) in scheduling real-time applications and non-real-time applications, where the schedulability of each real-time application can be validated independently of other applications in the system. We replace the underlying earliest-deadline-first OS scheduler of the open system architecture by W.S. Liu, et al. (1997) with a rate-monotonic OS scheduler. The motivation behind this work is that many existing operating systems may not support the earliest deadline first scheduling very well. We propose to use the idea of sporadic servers to preserve CPU cycles for applications. We also develop schedulability tests for real-time applications which adopt the rate monotonic scheduling algorithm, the earliest deadline first scheduling algorithm, the priority ceiling protocol, and the stack resource policy. We allow tasks in each application to share local and global non-preemptable resources. A global resource synchronization mechanism is proposed. This paper provides a fixed-priority-based alternative for the important open system architecture.

Typically, two's complement is chosen to represent numbers since arithmetic operations of addition and subtraction are easy to perform. However, due to sign extension, an arithmetic operation for small dynamic data ranges may require switching power in the entire word length. Herein, we develop a two's complement adder with the dynamic-range determination and sign-extension units to reduce power consumption. According to the actual data range by minimizing sign-extension bits, only partial functional blocks of an adder are active to generate a final result of which sign bit is then extended to match the original word length. Experimental results demonstrate that our 32-bit carry-lookahead adder has 22.9% power reduction than the conventional one while dynamic ranges of input data are the Gaussian distribution with a mean of 16 bits and a standard deviation of 8 bits.
