An interesting class of intelligent tutoring systems are systems that are able to detect and recognize affective responses and states in students, and use such data to adapt its feedback, guidance and instruction. The article presents affective responses and states considered relevant for learning, and methods that have been proposed or used to detect such responses and states. We focus on the aff

Since many years, international tax law experts debate the relevance of changes to OECD Commentaries for the purpose of the interpretation of previously concluded tax treaties. Although, generally, most experts seem averse to the idea of an ambulatory approach to the usage of OECD Commentaries, they are reluctant to exclude this idea altogether. Such a position raises an important issue of justifi

This chapter discusses several different aspects of the energy balance and physiological homeostasis of incubating birds, ranging from systematic, geographical and life history related variation in energy costs of incubation, to thermal considerations for birds on the nest, links between energy expenditure and fitness, and non-energetic costs of incubation. Our review of the literature shows that,

We study the interaction between two neutral plane-parallel dielectric bodies in the presence of a highly asymmetric ionic fluid, containing multivalent as well as monovalent (salt) ions. Image charge interactions, due to dielectric discontinuities at the boundaries, as well as effects from ion confinement in the slit region between the surfaces are taken fully into account, leading to image-gener

Experientialist semantics has contributed to a broader notion of linguistic meaning by emphasizing notions such as construal, perspective, metaphor and embodiment, but has suffered from an individualist concept of meaning and has conflated experiential motivations with conventional semantics. We argue that these problems can be redressed by methods and concepts from phenomenology, through a case s

Abstract Objective. Our aims were to investigate the natural history of biopsy-proven non-alcoholic fatty liver disease (NAFLD) in Sweden, its associated complications, the clinical and biochemical factors associated with more advanced liver disease and the survival rate with a mean follow-up time of 27 years. Material and methods. All subjects participating in the population-based prospective coh

Homogeneous charge compression ignition (HCCI) presents new challenges in combustion phasing control due to the lack of direct ignition trigger. In addition, recompression HCCI possesses cycle-to-cycle coupling through trapping a large portion of the exhaust gas in the cylinder. This paper examines the change in the cycle-to-cycle coupling around different operating points in recompression HCCI an

This report provides a summary of the third meeting of the Harmonising Outcome Measures for Eczema (HOME) initiative held in San Diego, CA, U.S.A., 6-7 April 2013 (HOME III). The meeting addressed the four domains that had previously been agreed should be measured in every eczema clinical trial: clinical signs, patient-reported symptoms, long-term control and quality of life. Formal presentations

Substantial variation in milk coagulation properties has been observed among dairy cows. Consequently, raw milk from individual cows and breeds exhibits distinct coagulation capacities that potentially affect the technological properties and milk processing into cheese. This variation is largely influenced by protein composition, which is in turn affected by underlying genetic polymorphisms in the

This paper reviews the performance of MBR in treating high strength industrial wastewater. The scope covers the operation, constraints and mitigation of the system in general views. High strength wastewater can be successfully treated by using membrane bioreactor (MBR) in different conditions according to the types and characteristics of wastewater and also MBR parameters operational control. High

There is a burgeoning literature based on using panel cointegration techniques to study the relationship between energy consumption and GDP. Most panel cointegration tests employed take no cointegration as the null hypothesis. The current paper illustrates how a rejection by such a test cannot be taken as evidence of cointegration for the panel as a whole, a fact that seems to have gone largely un

This work presents an efficient finite element based scheme for the prediction of process properties and especially the material condition of workpiece surfaces after turning. This is achieved by using a database generated with the help of a micromechanically motivated material model - capable of simulating interactions of phase transitions and plasticity - for the efficient post-processing of a m

BACKGROUND AND PURPOSE: Ensuring data integrity in radiotherapy is of major importance and a complex task. The aim of this study was to compare three different combinations of treatment planning and record and verify systems with respect to data integrity. MATERIALS AND METHODS: A software for comparison of treatment parameters in DICOM-RT files was developed using the MATLAB R2010a (MathWorks I

We evaluated the performance of the Disease State Index (DSI) method when predicting progression to Alzheimer's disease (AD) in patients with subjective cognitive impairment (SCI), amnestic or non-amnestic mild cognitive impairment (aMCI, naMCI). The DSI model measures patients' similarity to diagnosed cases based on available data, such as cognitive tests, the APOE genotype, CSF biomarkers and MR

This paper proposes that the maximum entropy principle can be used for determining the drop size distribution of hydrometeors. The maximum entropy principle can be applied to any physical systems with many degrees of freedom in order to determine a distribution of a variable when the following are known: 1) the restriction variable that leads to a homogeneous distribution without constraint and 2)

Given a set of commodities and a network where some arcs can fail while others are reliable, we consider a routing problem with respect to a survivability requirement that each commodity can be split among pairs of failure-disjoint paths. Two paths p and p′ form a pair of failure-disjoint paths if they share only reliable arcs. The same flow is sent over p and p′, but the flow sent on a common rel

Small words like ‘yes’ and ‘no’ play an important part in our daily communication, but do we clearly know where they come from? Their origin is rather mysterious. We do not know if we need these words at all, since some languages manage without them. For instance, speakers of Celtic languages answer affirmatively and negatively by repeating verbs. However, functional motivations to have ‘yes’ and

Many independent publishers are today offering digital libraries with fulltext archives. In an attempt to provide a single user-interface to a large set of archives, DTVs Article Database Service, offers a consolidatedinterface to a geographically distributed set of archives. While this approach offers a tremendous functional advantage to a user, the delays caused by the network and queuing delays

At the interface between two regions, for example the air–liquid interface of a lipid solution, there can arise non-equilibrium situations. The water chemical potential corresponding to the ambient RH will, in general, not match the water chemical potential of the solution, and the gradients in chemical potential cause diffusional flows. If the bulk water chemical potential is close to a phase tra
