Post-Doctor in Informatics with Specialization in Software Testing, Sweden

The position is offered within the area of Informatics which at the University of Skövde is defined as the study of how information is represented, processed and communicated in artificial and natural systems, as well as how IT systems are used and developed to ensure usability for individuals, organizations or society. The positon has a specialization in Software Testing, which at the University of Skövde is part of Computer Science and entails study of basic theory and methodology for testing software. The concept includes, among other aspects, test design, test coverage criteria and test analysis, as well as complexity, algorithms and programming.

Application deadline: March 8th, 2016Reference number: HS 2016/87

This position mainly concerns research. The research is conducted within the TOCSYC project, a distributed research environment with focus on testing of critical system properties. The research environment extends over several universities and a research institute.
As a Postdoc in the project you will be involved in research and development of effective and efficient methods to test non-functional properties such as performance efficiency and robustness, in embedded systems using model-based and mutation-based approaches. The area of research can partly be adapted to the expertise of the applicant.

Collaboration between the partners in TOCSYC is close, which means that flexibility and willingness to collaborate are paramount. As a Postdoc in the project you will connect two work packages within the distributed research environment, at University of Skövde and Mälardalen University, and thus contribute to the coupling between these nodes in the area of model-based testing and mutation-based testing.

TOCSYC provides a strong international research-intensive environment with focus on testing non-functional properties in embedded systems, which is a critical issue for the Swedish export industry. You can read more about TOCSYC at www.tocsyc.se.

Qualification requirements

The qualification requirements are:
  • PhD in Informatics or equivalent subject or have a foreign degree deemed equivalent to a PhD, and have obtained the PhD not longer than three years prior to the application deadline. If there are special circumstances the PhD could have been obtained earlier
  • ability to communicate well, orally and in writing, in English.
Bases of evaluation
In addition to the qualification requirements, the bases of evaluation for this position are:
  • Degree of proficiency that is required for the employment (see the qualification requirements).
  • Good collaboration ability.
  • Good knowledge in software testing.
  • Good knowledge in mutation analysis.
  • Good knowledge in programming.
  • Good knowledge in UML.
For this position, special emphasis will be placed upon good collaboration ability and good knowledge in software testing.

The University of Skövde strives towards ethnical and cultural diversity and equal gender distribution within all employment categories. As the majority of the employees in the research environment are men, the University especially invites women to apply for this position.

The position as Post-Doctor is fulltime and done accordingly to the collective agreement between the Swedish Agency for Government Employers OFR-S, SACO-S and SEKO. The position is a temporary position for two years.

Your application

Your application must be marked with the reference number and provided to the Registrar, University of Skövde, Box 408, SE-541 28 Skövde, Sweden or by e-mail to registrator@his.se no later than deadline. The application must be submitted with an attested list of qualifications, certificate of degree and other certificates, a brief written account of scientific, pedagogical and other activities, a list of (all) publications and the work referred to, no more than five scientific publications (a minimum of two published during the last three years).

PhD Student Position in Elastic Resource Allocation for Query Optimization

IRIT Lab. (https://www.irit.fr/) - Pyramid Team - Paul Sabatier University - Toulouse - France Supervisor’s Names : Abdelkader Hameurlain (hameurlain@irit.fr) and Shaoyi Yin (Shaoyi.yin@irit.fr).

Pyramid Team (Dynamic Query Optimization in Large-scale Distributed Environments ; https://www.irit.fr/-Equipe-PYRAMIDE-) is likely to get a PhD scholarship for 3 years (Doctoral School MITT, http://www.edmitt.ups-tlse.fr/).

Context

In parallel and distributed large-scale environments (Cluster, Grid, Cloud), the Pyramid team addresses the main problems of query processing and optimization, targeting large volumes of data distributed in large scale. To manage a huge amount of data there are two approaches : parallel database systems and cloud systems (e.g. Hadoop, MapReduce, Spark, HDFS). The parallel database systems have been an important success, both in research in the early 90s and now in industry. They have enabled many applications handling large data volumes to meet their requirements in terms of performance (e.g. Response Time) and resource availability. It is recognized that parallel database systems are very expensive and require having high level skills within the company to administer the systems and databases. As for cloud systems, they allow a company to reduce these costs in term of infrastructure either by purchasing a server comprised of low-cost commodity machines or by renting a service in pay-per-use. Public Clouds provide on demand resources and services with advantages of scalability and elasticity. However, elasticity paradigm raises a new challenge regarding the design of efficient and profitable resource allocation models.

PhD Subject : Elastic Resource Allocation for Query Optimization

The objective is to design and develop an elastic resource allocation model for query optimization. In fact, the allocated resources (on the provider side) should increase or decrease in accordance with the demand of services (on the tenants side), in order to maintain a QoS and to meet the SLAs (Service Level Agreement). The main criteria of QoS taken into account are the performance (e.g. query response time) and the availability of services (e.g. data availability). As for the SLA, a kind of provider-consumer contract, it specifies a set of constraints to meet and objectives to reach, in terms of performance or service availability. The main challenge is to find the best trade-off between the tenants’ satisfaction in terms of QoS and the providers gain in terms of profitable resource management.

Requirements :

Distributed and Parallel Systems, Database Systems, Query Processing and Optimization, Cost Models, Cloud Systems, Hadoop, MapReduce, Spark, Programming Languages (C, C++, Java, Python, ...).

The application should include following documents (PDF format, see : http://www.edmitt.ups-tlse.fr/).

1- CV mentioning all your degrees
2- Motivation letter from the applicant explaining his/her choice of the proposed thesis subject
3- Recommendation letters
4- Details of your grades since you started higher education with ranking.

Applications in digital form (pdf) should be sent to : hameurlain@irit.fr

Application Deadline : February 8th, 2016

Start Date : September 1st, 2016.

Remuneration : the PhD Scholarship is approximatively 1684 Euros (Gross).
Once the candidate is selected by Pyramid team, he/she will be auditioned by a committee.
