37 INTRODUCTION With the increasing dependency on automobiles and trucks to transport people and goods, signalized traffic control systems become a critical element of a transportation network. Although traffic signals are placed to regulate the flow of vehicles, negative impacts include increased travel time, fuel consumption and vehicle emissions. Optimization of signal timing has been recogn...

In this paper we report our design and implementation of a new self-scheduling parallel programming language, SELSYN-C. Our approach to the challenge of parallel programming language design and implementation is twofold: (1) the design of simple extensions to C that are both easy to use, and useful for eeective compilation, and (2) the design of eecient and eeective scheduling strategies that c...

The Pulse Code Modulation (PCM) method of digitizing analog signals has become a stan~ard both in digital audio and in speech research, the focus of this paper. The solutions to some problems encountered in earlier systems at Haskins Laboratories are outlined, along with general properties of AID conversion. Specialized features of the current Haskins Laboratories system, which has also been in...

There exist a large number of scientiic and industrial applications with inherently unstructured parallelism which cannot be solved eeectively using a data parallel approach. In this paper we present TGEX, a generic tool for the parallel execution of unstructured problems on distributed memory computers. A general computational problem is rst expressed in terms of a computation task graph which...

The reliability and safety of diesel engines gradually decrease with the increase in running time, leading to frequent failures. To address problem that it is difficult for traditional fault status identification methods identify engine faults accurately, a method based on synchro squeezing S-transform (SSST) vision transformer (ViT) proposed. This can effectively combine advantages SSST proces...

The Synchro-Extracting Transform technique (SET) can capture the changing dynamic in a non-stationary signal which be applied for fault diagnosis of rotating machinery operating under varying speed or/and load conditions. However, time frequency representation (TFR) produced by SET affected noise contained signal, largely reduce accuracy diagnosis. This paper addresses this drawback and present...
