We describe a study of 168 software professionals to determine how relevant their education has been to their careers. Starting with a list of 57 topics, we asked the participants to indicate how much they learned in university, how much they know now, how useful the material has been and whether they would like to learn more. We conclude from the results that certain software engineering topic...

Active networks are aimed at incorporating programmability into the network to achieve extensibility. One approach to obtaining extensibility is to download router programs into network nodes. This programmability is critical to allow multipoint distributed systems to adapt to network conditions and individual clients’ needs. Although promising, this approach raises critical issues such as safe...

A games model of a programming language with higher-order store in the style of ML-references is introduced. The category used for the model is obtained by relaxing certain behavioural conditions on a category of games previously used to provide fully abstract models of pure functional languages. The model is shown to be fully abstract by means of factorization arguments which reduce the questi...

IEEE organization defined a standard for floatingpoint arithmetic, used by processing systems, in its directive 754 [1]. This directive encodes floatingpoint numbers using a maximum of 64 bits: 23 bit of fractional as single precision format and 52 bit of fractional as double precision format. The new multimedia terminals require low-power applications; the most important floating-point units (...

We present a method for providing response-time guarantees for multimedia traffic in Asynchronous Transfer Mode (ATM) networks. The method extends our ResponseTime Analysis (RTA) for ATM networks to better capture the behaviour of MPEG-type multimedia traffic. RTA is intended for admission control of hard real-time traffic, i.e., it determines if a new connection can be admitted without violati...

This paper explores the interplay between algorithm design and a computer’s memory hierarchy. Matrix transpose and the bit-reversal reordering are important scientific subroutines which often exhibit severe performance degradation due to cache and TLB associativity problems. We give lower bounds that show for typical memory hierarchy designs, extra data movement is unavoidable. We also prescrib...

RATIONALE The diagnosis of pleural malignant mesothelioma (MM) by effusion cytology may be difficult and is currently controversial. Effusion mesothelin levels are increased in patients with MM but the clinical role of this test is uncertain. OBJECTIVES To determine the clinical value of measuring mesothelin levels in pleural effusion supernatant to aid diagnosis of MM. METHODS AND MEASUREM...
