We present a motion planning methodology to allow for a group of mobile sensors to scan a given polygonal area and map the radiation levels over it. We assume low radiation levels, which implies that detectors obtain meaningful measurements at small distances, and that radiation detectors are carried around mounted on mobile robots. The area is discretized at a resolution suggested by the footp...

This paper presents design options for 3D SRAM cells to enable ultra-high density 3D SRAM based on monolithic 3D integration. Our target technology offers one tier of NMOS devices, another for PMOS devices, and nano-scale inter-tier vias. Choosing the most compact 22nm 2D SRAM as our design baseline, we first achieve a 33% footprint area reduction by simply splitting the NMOS and PMOS devices i...

One of the most efficient ways of generating goal-directed walking motions is synthesising the final motion based on footprints. Nevertheless, current implementations have not examined the generation of continuous motion based on footprints, where different behaviours can be generated automatically. Therefore, in this paper a flexible approach for footprint-driven locomotion composition is pres...

In this paper we examine the issue of optimizing disk usage and scheduling large-scale scientific workflows onto distributed resources where the workflows are data-intensive, requiring large amounts of data storage, and the resources have limited storage resources. Our approach is two-fold: we minimize the amount of space a workflow requires during execution by removing data files at runtime wh...

Global warming is accelerating and the world urgently needs a shift to clean and renewable energy. Hydropower is currently the largest renewable source of electricity, but its contribution to climate change mitigation is not yet fully understood. Hydroelectric reservoirs are a source of biogenic greenhouse gases and in individual cases can reach the same emission rates as thermal power plants. ...

Developers create paths for users to tread. Some users will stay on the beaten track; others will diverge and take risky shortcuts. If user-preferred and developer-created paths diverge too much, it is time for the developer to consider a new path. A case in point is the humble password. They fill an important developer need: a cheap and easy mechanism to control access and enforce accountabili...

The success of a case-based reasoning system depends critically on the performance of the retrieval algorithm used and, specifically, on its efficiency, competence, and quality characteristics. In this paper we describe a novel retrieval technique that is guided by a model of case competence and that, as a result, benefits from superior efficiency, competence and quality features.

In the United States, surgeons perform an estimated 200,000 anterior cruciate ligament reconstructions (ACLRs) each year. Over the past decade, there has been a surge in interest in defining anterior cruciate ligament (ACL) anatomy to guide ACLR. With this renewed interest in the anatomical features of the ACL, particularly the insertion site, many authors have advocated an approach for complet...

We investigate the potential of foot biometric features based on geometry, shape and texture and present algorithms for a prototype rotation invariant verification system. An introduction to origins and fields of application for footprint-based personal recognition is accompanied by a comparison with traditional hand biometry systems. Image enhancement and feature extraction steps emphasizing o...

Phylogenetic footprints are short pieces of noncoding DNA sequence in the vicinity of a gene that are conserved between evolutionary distant species. A seemingly simple problem is to sort footprints in their order along the genomes. It is complicated by the fact that not all footprints are collinear: they may cross each other. The problem thus becomes the identification of the crossing footprin...
