A small extension to Java for class refinement

Muga Nishizawa, Shigeru Chiba
2008 Proceedings of the 2008 ACM symposium on Applied computing - SAC '08  
GluonJ was carefully designed so that the IDE can recognize a GluonJ program and reflect it on the coding support such as the code assist of Eclipse.  ...  This is significant for the industrial acceptability of a new language. A GluonJ program is written in standard Java with additional Java annotations.  ...  SAC'08 March 16-20, 2008, Fortaleza, Ceará, Brazil Copyright 2008 ACM 978-1-59593-753-7/08/0003 ...$5.00.

Slack time evaluation with RTSJ

Damien Masson, Serge Midonnet
2008 Proceedings of the 2008 ACM symposium on Applied computing - SAC '08  
We address in this paper the problem of jointly scheduling hard periodic tasks and soft aperiodic events using the Real-Time Specification for Java (RTSJ).  ...  We present the programming constraints of RTSJ and propose slack time evaluation and utilization algorithms which take these constraints into account.  ...  SAC'08 March 16-20, 2008, Fortaleza, Ceará, Brazil Copyright 2008 ACM 978-1-59593-753-7/08/0003 ...$5.00. 5 presents our simulations methodology and results.

SQL-IDS

Konstantinos Kemalis, Theodores Tzouramanis
2008 Proceedings of the 2008 ACM symposium on Applied computing - SAC '08  
The new approach on the one hand utilizes specifications that define the intended syntactic structure of SQL queries that are produced and executed by the web application and on the other hand monitors  ...  any particular target system, application environment, or DBMS; and, third, there is no need to modify the source code of existing web applications to apply the new protection scheme to them.  ...  To copy otherwise, or republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee.

Filtering drowsy instruction cache to achieve better efficiency

Roberto Giorgi, Paolo Bennati
2008 Proceedings of the 2008 ACM symposium on Applied computing - SAC '08  
In the case of instruction cache, we found that this can automatically achieved by coupling a tiny cache acting as a filter cache (IL0 cache) with a drowsy-cache.  ...  Our idea is to adaptively select the most used cache lines.  ...  To copy otherwise, or republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee.

Decentralized coordination strategies for the vehicle routing problem

Matteo Vasirani, Sascha Ossowski
2008 Proceedings of the 2008 ACM symposium on Applied computing - SAC '08  
This paper shows how to implement a decentralized decision strategy, based on an extended version of the Probability Collective (PC) framework.  ...  Distributed agent-based control systems are the ideal candidates to manage such dynamic and unpredictable application domains, like transportation systems.  ...  This research was partially supported by the Spanish Ministry of Science and Education through projects "THOMAS" (TIN2006-14630-C03-02) and "AT" (CONSOLIDER CSD 2007-0022, INGENIO 2010).  ...

A constraint hierarchies approach to geometric constraints on sketches

Christophe Jermann, Hiroshi Hosobe
2008 Proceedings of the 2008 ACM symposium on Applied computing - SAC '08  
We propose an approach that uses preferences on the constraints in order to deal with over-constrained geometric constraint problems.  ...  We also remark that any geometric constraint problem defined by imposing relations on a sketch becomes overconstrained as soon as the sketch is imposed as a weak constraint representing the designers intents  ...  SAC'08 March 16-20, 2008, Fortaleza, Ceará, Brazil Copyright 2008 ACM 978-1-59593-753-7/08/0003 ...$5.00.  ...
