The European Space Agency’s (ESA) ExoMars rover has recently been subject to a Phase A study led by EADS Astrium, UK. This rover mission represents a highly ambitious venture in that the rover is of considerable size ~200+kg with high mobility carrying a highly complex scientific instrument suite (Pasteur) of up to 40 kg in mass devoted to exobiological investigation of the Martian surface and sub-surface. The chassis design has been a particular challenge given the inhospitable terrain on Mars and the need to traverse such terrain robustly in order to deliver the scientific instruments to science targets of exobiological interest, We present some of the results and design issues encountered during the Phase A study related to the chassis. In particular, we have focussed on the overall tractive performance of a number of candidate chassis designs and selected the RCL (Science & Technology Rover Company Ltd in Russian) concept C design as the baseline option in terms of high performance with minimal mechanical complexity overhead. This design is a six-wheeled double-rocker bogie design to provide springless suspension and maintain approximately equal weight distribution across each wheel.

This paper presents an experimental performance study of implementations of three symbolic algorithms for solving band matrix systems of linear algebraic equations with heptadiagonal, pentadiagonal, and tridiagonal coefficient matrices. The only assumption on the coefficient matrix in order for the algorithms to be stable is nonsingularity. These algorithms are implemented using the GiNaC library of C++ and the SymPy library of Python, considering five different data storing classes. Performance analysis of the implementations is done using the high-performance computing (HPC) platforms “HybriLIT” and “Avitohol”. The experimental setup and the results from the conducted computations on the individual computer systems are presented and discussed. An analysis of the three algorithms is performed.

PurposeIn this article, we identify various foodservice-related attributes that are important for undergraduate students residing in hostels and avail service from specific foodservice providers. We also investigate the performance of attributes to determine areas where the foodservice providers should maintain a high performance or where improvement is required.Design/methodology/approachWe apply the Kano methodology to design the questionnaire for 24 different attributes. For each attribute, we construct three questions; namely, functional type, dysfunctional type, and performance of the hostel foodservice. We collect a total of 317 responses. We use multiple methods to determine the dominant category. Finally, combining the values of these methods, we study relative positions of the attributes in the importance–performance grid.FindingsBased on the Kano categorization, quality-related attributes are most important, followed by hygiene, comfort, availability, variety, and time, in the descending order. The gender of the respondent plays an important role in categorization of some attributes. Using the importance–performance analysis, we identify the attributes where the foodservice provider should maintain a high performance or where improvement is required. Improvements in some attributes are difficult due to foodservice provider's self-assessment of high performance or high difficulty for improvement.Originality/valueIn this study, we examine the importance of various foodservice attributes among undergraduate residential students. We combine multiple methods of Kano categorization to compute importance values of the attributes. We also investigate the reasons behind the gap between student's and foodservice manager's perception of the performance of these attributes.
