We evaluate the on-node interference caused when co-locating traditional high-performance computing applications with a big-data application. Using kernel benchmarks from the NPB suite and a state-of-art graph analytics code, we explore different process placements and effects they have on application performance. Our results show that the most memory intensive HPC application (MG) experienced the...
Multi-view subspace clustering aims to partition a set of multi-source data into their underlying groups. To boost the performance of multi-view clustering, numerous subspace learning algorithms have been developed in recent years, but with rare exploitation of the representation complementarity between different views as well as the indicator consistency among the representations, let alone considering...
Particle Swarm Optimization (PSO) is a powerful algorithm that can search a solution for a function which contains a large number of peaks and valleys. However, PSO might encounter a difficulty when the function gets more complex or the number of attributes (dimensions) grows larger. This paper proposes a modification of PSO by using the incremental attribute strategy along with the centroid of particle's...
Workflow Management Systems (WfMSs) are a type of middleware that enables the execution of automated business processes. Users rely on WfMSs to construct flexible and easily maintainable software systems. Significant effort has been invested into standardising languages for business processes execution, with standards such as the Web Services Business Process Execution Language 2.0 or the Business...
The German SpaceBot Cup is a robotics competition that has its first edition in 2013. A second edition is expected by the end of 2015. The SpaceBot application scenario involves typical exploration tasks carried out on a planetary surface after landing on a planet. Competitors' robots are challenged to locate and identify objects, and then convey them to a base station. This activity is meant to be...
The usage of Software Defined Radio (SDR) even in Consumer Electronics (CE) devices is becoming more and more important because it provides high flexibility and reconfigurability. Although a real-time SDR implementation even of state of the art systems such as LTE-A+ or DVB-T2 using General Purpose Processors (GPPs) is possible, the performance of SDR applications is still an interesting research...
This paper proposes a new hybrid encoding of finite linear CSP to SAT integrating order and log encodings. The former maintains bound consistency by unit propagation and works well for instances with small/middle domain sized variables and/or arity of constraints. The latter generates smaller CNF and is suitable for instances with larger domain sized variables, but its performance is not good in general...
An any-time approach to extract the deductive arguments in favor of a given conclusion from a set of formulas is proposed. Since the number of such arguments can be exponential in the worst-case, the approach focuses first on a series of arguments with mutually independent supports before it considers additional arguments. It is developed in the standard clausal Boolean framework and it is based on...
This paper describes the third round of the Java Unit Testing Tool Competition. This edition of the contest evaluates no less than seven automated testing tools! And, like during the second round, test suites written by human testers are also used for comparison. This paper contains the full results of the evaluation.
Particle Swarm Optimization is motivated by collective behavior in the nature. Earlier PSO variants were biased and rotationally variant because of dimension by dimension method. Clerc proposed Standard PSO 2011 version to overcome the bias which modifies velocity in a geometrical way. Particle Swarm Optimization is an optimization technique having few parameters to tune. The neighborhood topology...
In 2010 the Australian government commissioned the Australian Learning and Teaching Council (ALTC) to undertake a national project to facilitate disciplinary development of threshold learning standards. The aim was to lay the foundation for all higher education providers to demonstrate to the new national higher education regulator, the Tertiary Education Quality and Standards Agency (TEQSA), that...
The usability of Web sites and online services is of rising importance. When creating a completely new Web site, qualitative data are adequate for identifying the most usability problems. However, changes of an existing Web site should be evaluated by a quantitative benchmarking process. The proposed paper describes the creation of a questionnaire that allows a quantitative usability benchmarking,...
For many years the authors have coordinated a large engineering design subject, having a cohort of approximately 300+ students. Lectures are supported by tutorials of approximately 32 students which incorporate collaborative team learning activities and project-based learning. Each tutor is responsible for grading the assessment tasks for students in their tutorial. A common issue is how to achieve...
Worst case execution time analysis based on measurements requires large test suites to obtain reliable numbers. We are thus developing tools to efficiently generate these test sets in a whitebox-testing approach. To make project progress measurable and guard against regressions, a benchmarking suite is sought for. We present a set of requirements that have been collected and outline the design of...
