This paper reports on an investigation into the basic properties and requirements of automatic speech recognition as an input device to a trial human computer interface. The experiments required subjects to carry out a simulated target acquisition and report filling task, with the available input devices being automatic speech recognition, trackball, function keys or a simultaneous combination ...

The paper presents a concept of single event equivalence to be used in the sequential circuit fault simulator. The concept dynamically identifies the equivalent faults for a simulated pattern. It combines advantages of the fanout-free region, critical path tracing and the dominator concept, which were applicable only to combinational circuit fault simulation. The implemented fault simulator, SE...

The method for finding fuzzy optimal solution of fully fuzzy critical path (FFCP) problems i.e., critical path problems in which all the parameters are represented by fuzzy numbers, is at best scant; possibly non-existent. In this paper, a method is proposed to find the fuzzy optimal solution of FFCP problems, together with a new representation of triangular fuzzy numbers. This paper will show ...

Risk management is a process aimed at enhancement, developing the level of security in an organization. It gives the organization a broad view of the risks that can affect its productivity and performance, and enables it to make appropriate risk management decisions. This paper presents a new fuzzy method for measuring risk element criticality in a fuzzy project network. There have been several...

A novel technique to improve energy e ciency is disclosed. It relies on a fault-tolerance mechanism for timing constraints based on speculative execution technique. Since power reduces quadratically with supply voltage, supply voltage reduction can result in substantial power savings. However, it also causes larger gate delay, and thus clock must be slow down in order not to violate timing cons...

Software is a major expense for most organizations and is on the critical path to almost all organizational activities. Individual software development organizations in general strive to develop higher quality systems at a lower cost for both their internal and external customers. Yet the processes used to develop such software are still very primitive in the way that experience is incorporated...

We present a new sequential normal basis multiplier over GF (2). The gate complexity of our multiplier is significantly reduced from that of Agnew et al. and is comparable to that of Reyhani-Masoleh and Hasan, which is the lowest complexity normal basis multiplier of the same kinds. On the other hand, the critical path delay of our multiplier is same to that of Agnew et al. Therefore it is supp...

Although recursive filters are not possible to pipeline at the algorithmic level, it is possible to introduce logic level pipelining and thereby increase the maximal sample rate. This is because the critical path gets shorter so that the circuitry can be clocked faster. However, the latency of the operations increases with increased pipelining. It is of interest to find the optimal degree of pi...

This paper presents a method for optimizing software testing efficiency by identifying the most critical path clusters in a program. We do this by developing variable length Genetic Algorithms that optimize and select the software path clusters which are weighted in accordance with the criticality of the path. Exhaustive software testing is rarely possible because it becomes intractable for eve...

In this work we propose a self-adaptive clock based on a ring oscillator as the solution for the increasing uncertainty in the critical path delay. This uncertainty increase forces to add more safety margins to the clock period which produces a circuit performance downgrade. We evaluate three self-adaptive clock systems: free running ring oscillator, infinite impulse response filter controlled ...
