Collaboration activities are particularly difficult in e-learning environments, where the intention is to provide students with valuable learning experiences through working in teams and sharing a common goal. These activities are often conducted in an ad hoc manner with lack of proper assessment and control over learning outcomes. In this article, we propose the idea of enhancing the effective...

Sensing surface textures by tou capability for robots. Until recently it w a compliant sensor with high sen resolution. The GelSight sensor is co sensitivity and resolution exceeding fingertips. This opens the possibility recognizing highly detailed surface tex sensor, when pressed against a surfac map. This can be treated as an image, a the tools of visual texture analysis. W simple yet effect...

This exploratory study set out to analyse discourse about 'friendly bacteria' by scrutinising data from focus groups convened to discuss participants' reasons for choosing probiotic food products and to set their use of probiotics in context in relation to other food choices. In discussing food choice and dietary patterns, participants in the five focus groups reported here drew on a major inte...

Eating location has been linked with variations in diet quality including the consumption of low-nutrient energy-dense food, which is a recognised risk factor for obesity. Cross-sectional data from 4736 adults aged 19 years and over from Years 1-6 of the UK National Diet and Nutrition Survey (NDNS) Rolling Programme (RP) (2008-2014) were used to explore food consumption patterns by eating locat...

Probes with GPS devices reveal useful information for traffic conditions and patterns. The high level of noises and lack of details make it challenging to mine behavioral patterns from the raw data collected. Behavioral patterns are essential for understanding the underlying structures of data sources and various real-world interests such as traffic planning, vehicle operations and anomalous/po...

What are the patterns that typical network attackers exhibit? For a given malicious network behaviors, are its attacks spread uniformly over time? In this work, we develop MalSpot, multi-resolution and multi-linear (Multi) network analysis system in order to discover such malicious patterns, so that we can use them later for attack detection, when attacks are concurrent with legitimate traffic....

Then why are researchers and doctors striving to cure Alzheimer’s and other typical diseases of old age? Let us return to the good old days and the picturesque habits we have heard about in distant populations: the Eskimo people who left their old people alone on the ice to die; or those tribes in some wild place in the Amazon or Africa who ate their elderly people to absorb their experience an...

Darwin-FIRST, is an Artificial Intelligence procedure to automatically retrieve intelligence diluted in huge databases. FIRST stands for Full Information Retrieval System on Thesaurus, one expert system aided by agents and Darwin stands for Distributed Agents to Retrieve the Web Intelligence, a network of FIRST nodes. FIRST algorithms and agents extract from databases their inherent intelligent...

Workload characteristics in a modern networking environment are very dynamic. In order to maximize performance continuously, it is natural to explore the possibility of intelligent systems which can take cognizance of the dynamics in workload and adapt themselves for future control applications. In this paper, we propose a mechanism which represents the previous state of the system as a string....

Many models of aggression include negatively valenced emotions as common elicitors of aggressive behavior. Yet, the motivational direction of these emotions is not taken into account. The current work explored whether sensitivity to a negative emotion associated with behavioral avoidance-disgust-will predict lower levels of aggression. Five studies tested the hypothesis that disgust sensitivity...
