PhD Student Position in Elastic Resource Allocation for Query Optimization IRIT Lab.

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

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

Scientific 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 tenantsâ satisfaction in terms of QoS and the providersâ 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, ...).

Salary grade: E13 TV-L Berliner Hochschulen Max. 4 years, part-time employment may be possible

Working field:

The extension of the Internet into the physical world (Internet of Things) requires a combination of many research areas like Web technologies, distributed systems, database systems, networking, sensor networks, Semantic Web, Linked Data, etc. This synergy facilitates the interconnectivity and interoperability of the Things on the Web. The goal is to enable simple access to data irrespective of their source (sensors, embedded systems, Web, Semantic Web, Linked Data, social media, e.g., Twitter, etc.), scalable management of this data using a single access abstraction, and a single data model. This will enable simple standardized ways to derive useful insights from the dynamic linked data. However, the sheer size, dynamics, and heterogeneity of the data in the IoT realm poses novel and unique challenges, which we investigate in Open Distributed Systems group at TU Berlin. Currently we are looking for a PhD researcher. A successful candidate will conduct her/his independent research in one of these areas and will play an active role in teaching and supervising of students.

2 PhD student positions in Architecture and Structural Design

Chalmers Architecture has a strong profile on sustainability working with central societal challenges in the built environment with explorative and practice-based approaches. The department’s teaching and research in architecture, urbanism and design processes integrate practice-based, artistic and scientific methods to explore the broad aspects of architecture – from building technology, physical design, and spatial structures to design methods, transformation of built environments and its role in sustainable development.

The department of Architecture has around 100 employees, and is located at Chalmers campus Johanneberg. The department has around seventy teachers and researchers working with teaching and research, and around twenty doctoral students. The administration consists of around ten persons.

Information about the division

The division of Architectural theory and methodology carries out research and education in the field of theory, history and practice of architecture and planning. The division focuses on different aspects of architecture, such as materials and technology, visualization and modeling, theory and history, as well as dialogue processes and design methodology. Knowledge is developed in collaboration with both external actors and with other departments at Chalmers. Here is not least the Area of Advance Built Environment an important platform.

Architecture and Structural Design is a research field strongly related to the architectural design process. This is characterized by developing, exploring and evaluating different solutions in an iterative design process. Today the field is under rapid development and span; from analysis of complex contexts, consisting of topological, geographical, social, economic, cultural, historical, etc. information that sets the boundaries, to parametric modelling of shape, computational modelling of different physical behavior and manufacturing processes ranging from smart materials to optimized structures covering all scales of interest.

Major responsibilitiesYou are invited to apply for a PhD student position in the project "Form finding in structures". The research project includes different aspects of form finding in different scales from material design to global shape of an architectural artifact. The project focus on:

• developing interactive computational models and tools for real time simulation and form finding of structures.
• developing user interfaces of computational tools which will promote creative cooperation between architects and engineers already in the conceptual stage of the design.
• using computational tools connecting parametric design soft wares with computational engines (FEM) to pursue different types of analysis such as structural / building physics / acoustic / lighting analysis
• exploring different concepts/forms by prototyping
• evaluating the working procedure using the computational tools in a real context.

Depending on your background and interest it is possible to choose focus within the topics above. An application can be for example textile membrane structures that offer a great potential for the built environment from architectural as well as engineering point of view since they with a minimum of material can span large distances, promoting space, light and sustainability. Other applications of interest can be how different architectural forms, free forms, can be generated and realized by panelization /tessalation with supporting truss and/or frame structures or other types of loadbearing systems. The realization of form through smart materials and advanced production/construction tools are also important research issues.

Your PhD-project in Architecture and Structural Design is supported by the Chalmers foundation and will be a natural part of the activities within the Area of advance Built Environment.

Position summaryFull-time temporary employment. The position is limited to a maximum of five years.

Qualifications

To qualify as a PhD student, you must have a master's level degree corresponding to at least 300 higher education credits in a relevant field. A suitable background is a Master of Science or a Master of Architecture in Architecture and Engineering, Structural engineering with emphasis on structural mechanics and computational methods (e g FEM) or corresponding level of academic education for example in mathematics. Some years of practical experience in Architecture and or Structural engineering is welcome. The position requires verbal and written communication skills in Swedish and English. If Swedish is not your native language, you should be able to teach in Swedish after two years. Chalmers offers Swedish courses.

Information about the research group
The Computer Vision Group conducts research in the field of automatic image interpretation. The group targets both medical applications, such as the development of new and more effective methods and systems for analysis, support and diagnostics, as well as general computer vision applications including autonomously guided vehicles, image-based localization, stereo and structure-from-motion. The main research problems include mathematical theory, algorithms and machine learning for inverse problems such as reconstruction, segmentation and registration.

Information about the project
State-of-the-art systems for 3D reconstruction from 2D images are mainly based on geometric concepts and the resulting, reconstructed 3D model is a purely geometric description of the scene. In this project, we would like enhance the model with semantic information, and be able to recover both scene geometry and semantics simultaneously. The idea is that by recovering both semantics and geometry, the two different sources of information will complement and support each other in order to improve the interpretation of the scene.

The research will be focused on mathematical tools appropriate for the above challenge. We have previously worked a lot on geometric reconstruction methods and this will form the basis for the new project. Another relevant example from our current research is the development of mathematical models and optimization methods for Markov Random Fields (MRFs) in combination with Deep Learning. This will be key in order to combine geometry and semantics within a single, joint framework.

Major responsibilitiesYour major responsibilities are to pursue your own doctoral studies. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing, both in Swedish and in English. The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 per cent of working hours.

Position summaryFull-time temporary employment. The position is limited to a maximum of five years.

QualificationsTo qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in a relevant field (physics, mathematics or computer science).

The position requires sound verbal and written communication skills in Swedish and English. If Swedish is not your native language, you should be able to teach in Swedish after two years. Chalmers offers Swedish courses.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
