We describe a low-cost wearable system that tracks the location of individuals indoors using commonly available inertial navigation sensors fused with radio frequency identification (RFID) tags placed around the smart environment. While conventional pedestrian dead reckoning (PDR) calculated with an inertial measurement unit (IMU) is susceptible to sensor… (More)
Any preservation effort must begin with an assessment of what content to preserve, and web archiving is no different. There have historically been two answers to the question "what should we archive?" The Internet Archive's broad entire-web crawls have been supplemented by narrower domain- or topic-specific collections gathered by numerous libraries. We can… (More)
Web archiving initiatives around the world capture ephemeral web content to preserve our collective digital memory. In this paper, we describe initial experiences in providing an exploratory search interface to web archives for humanities scholars and social scientists. We describe our initial implementation and discuss our findings in terms of desiderata… (More)
Encapsulation of autologous adult cartilage cells (chondrocytes) in hydrolytically degradable hydrogels may provide a clinically viable tissue engineering therapy for replacement of damaged or osteoarthritic cartilage. When designing a tissue engineering scaffold, it is crucial to evaluate adult chondrocytes due to their limited growth potential. The… (More)
This paper provides a brief overview of my work with the GeoCities web archive. Asking the question of " can we find community, " I use it as a case study to explain various methods for distantly reading web archives.
BACKGROUND AND OBJECTIVES Children in state care ('looked after children') have poorer health than children who are not looked after. Recent developments in Scotland and elsewhere have aimed to improve services and outcomes for looked after children. Routine monitoring of the health outcomes of looked after children compared to those of their non-looked… (More)
The synthesis of clickable polysaccharides was achieved by using alkynylated 1,6-anhydro glucopyranose as a monomer and BF3·OEt2 as an effective catalyst. Subsequent click conjugation with polyethylene glycol (PEG) afforded PEG-grafted polysaccharides in nearly quantitative efficiency.
pH-Responsive polymers have great potential in biomedical applications, including the selective delivery of preloaded drugs to tissues with low pH values. These polymers usually contain acid-labile linkages such as esters and acetals/ketals. However, these linkages are only mildly pH-responsive with relatively long half-lives (t1/2 ). Orthoester linkages… (More)
Use of computational methods for exploration and analysis of web archives sources is emerging in new disciplines such as digital humanities. This raises urgent questions about how such research projects process web archival material using computational methods to construct their findings. This paper aims to enable web archives scholars to document their… (More)
