Computer-based human activity recognition of daily living has recently attracted much interest due to its applicability to ambient assisted living. Such applications require the automatic recognition of high-level activities composed of multiple actions performed by human beings in a given environment. We propose a deep neural architecture for kitchen activity recognition, which uses an ensembl...

The purpose of this study was to evaluate the chill chain in school catering by monitoring time-temperature profiles. Chilled ready-to-eat foods have been chosen as subject of this study because of their high risk due to their production, storage and distribution steps, separated in time, followed by consumption without any further thermal treatment. In order to integrate the effects of storage...

In [2] it was conjectured that all integer sequences (ak)k∈Z satisfying 0 ≤ ak−1 + λak + ak+1 < 1 (k ∈ Z) for real λ with |λ| < 2 are periodic. This question arose in the study of shift radix systems. The conjecture is trivially true for λ = −1, 0, 1. A computer assisted proof for λ = 1− √ 5 2 was given by Lowenstein, Hatjispyros and Vivaldi [5], where also the solution for λ = 1+ √ 5 2 is ment...

In the large compound kitchens of the gold mines of the Witwatersrand, where food is prepared for over a quarter of a million Bantu workers, there is a present trend to replace open cooking by pressure cooking. Of the food consumed, the vegetable stew is the chief, and sometimes the sole, source of vitamin C; however, since scurvy occurs infrequently, the amount of the vitamin provided up to no...

Deployment of improved biomass burning cookstoves is recognized as a black carbon (BC) mitigation measure that has the potential to achieve health benefits and climate cobenefits. Yet, few field based studies document BC concentration reductions (and resulting human exposure) resulting from improved stove usage. In this paper, data are presented from 277 real-world cooking sessions collected du...

BACKGROUND Paediatric burns are a significant international public health problem. Developing and developed countries report similar challenges regarding paediatric burn prevention programs. Paediatric burns requiring healthcare often incur significant health and opportunity costs, death or long-term disability. This paper reviews international burn prevention strategies, and considers implemen...

Abbot JM, Byrd-Bredbenner C. Development of a Self-Directed Home Kitchen Makeover for Mothers of Young Children. The Forum. 2009;14:1-7. Available online at: www.ncsu.edu/ffci This paper describes formative research guiding the development of an intervention designed to improve the ability of mothers of young children to plan, prepare, and serve healthy family meals. Interviews showed that the ...

With seed support (no Co-PI salary nor Ph. D student) from an NSF-funded Engineering Research Center (ERC), we have collected multimodal data—audio, video, Inertial Measurement Units (IMUs), and motion capture data—of individuals working in a kitchen [1]. To record human behavior in settings that are as natural as possible, we have installed a fully operational kitchen and captured 40 subjects ...

We present the representation and acquisition of semantic objects maps (SOMs) that can serve as information resources for autonomous service robots performing everyday manipulation tasks in kitchen environments. These maps provide the robot with information about its operation environment that enable it to perform fetch and place tasks more efficiently and reliably. To this end, the semantic ob...

We describe a feature extraction method for general audio modeling using a temporal extension of Independent Component Analysis (ICA) and demonstrate its utility in the context of a sound classification task in a kitchen environment. Our approach accounts for temporal dependencies over multiple analysis frames much like the standard audio modeling technique of adding first and second temporal d...
