The core of adaptive system is the user model that is representation of information about an individual. User model is necessary for an adaptive system to provide the adaptation effect, i.e., to behave differently for different users. The system that collects user information to build up user model and reasons out new assumptions about user is called user modeling system (UMS). There are two main tendencies towards implementing UMS: domain-independent UMS and domain-dependent UMS. The latter is called generic UMS known widely but our approach focuses on the domain-dependent UMS applied into adaptive e-learning especially. The reason is that domain-independent UMS is too generic to “cover” all learners’ characteristics in e-learning, which may cause unpredictable bad consequences in adaptation process. Note that user is considered as learner in e-learning context. Many users’ characteristics can be modeled but each characteristic is in accordance with respective modeling method. It is impossible to model all learners’ characteristics because of such reason “there is no modeling method fit all characteristics”. To overcome these obstacles and difficulties, we propose the new model of learner “Triangular Learner Model (TLM)” composed by three main learners’ characteristics: knowledge, learning style and learning history. TLM with such three underlying characteristics will cover the whole of learner’s information required by learning adaptation process. The UMS which builds up and manipulates TLM is also described in detail and named Zebra. We also propose the new architecture of an adaptive application and the interaction between such application and Zebra.

Abstract
We present work in the domain of Virtual
Platforms, based on the QEMU emulator. Virtual
Platforms allow software and drivers to be developed in
parallel with the development of hardware, avoiding re
design and long delay times in SW development. This
work allows designers to plug SystemC models into the
virtual platforms that QEMU offers (We focused on two
of the available platforms: x86 PC and ARM's
VersatilePB) The new aspect of this work is the
technology we have developed to connect between
QEMU and SystemC. We have developed a virtual
device to link QEMU and SystemC, and a bridge to
manage the OSCI SystemC2.2.0 simulator. This bridge
accomplish the task of synchronize efficiency the two
simulators, using a strategy of freezeandupdate on the
SystemC simulator to achieve a good performance.
Connection with the SystemC device is done using TLM
2.0 sockets and makes use of DMI. Also we present the
same emulator wrapped for a TLM2.0 Initiator module.
With this wrapper, this QEMU module can be used in a
standard SystemC simulation environment as an
Initiator that accesses some (but not necessary all) of its
system devices through a standard TLM2.0 socket.

Fibre Bragg gratings (FBGs) are an integral component of optical fibre based communication systems for signal processing. Uniform FBGs and phase-shifted FBGs find major applications as add-drop filters in dense wavelength division multiplexing (DWDM) systems where these are used to filter out channels and to shape the signal spectrum. We investigate numerically the spatiotemporal deformation of pulses as they propagate through the gratings. In particular, the effect on the pulse dynamics of phase shift or defect present in the gratings, often introduced intentionally in a grating to generate a narrow transmission spike within the stopband, is studied in time domain. This study is of significance since the deformation in the pulse in time limits the maximum bit rate achievable, and hence the pulse duration and shape need to be analysed and controlled accurately. A time domain numerical tool based on the Transmission Line Modelling (TLM) method is developed to study the pulse dynamics. The results obtained give useful information about the signal dynamics in gratings with defects, including the signal oscillations trapped in the defect, to be considered in applications such as while designing spectral filters.

High-voltage 4H silicon carbide diodes with breakdown voltages above 3500 V were
processed and characterized by using diﬀerent techniques. Measurement results of the electrical
properties of p+−ν−n and Schottky high-voltage diodes are presented. The achieved Schottky
barrier height at room temperature was estimated to be Φb = 1.17 eV from IV measurements.
The p+−ν−n diodes showed negligible leakage current densities of Jr ≤ 0.5 µA cm−2 at 1000 V
reverse bias. We also present a simple model to quantitatively characterize excess currents
observed under low forward biases in diﬀerent diode structures.

The development of embedded systems requires the development of increasingly complex software and hardware platforms. Full system simulation makes it possible to run the exact binary embedded software including the operating system on a totally simulated hardware platform. Whereas most simulation environments do not support full system simulation, or do not use any hardware modeling techniques, or have combined different types of technology, SimSoC is developing a full system simulation architecture with an integrated approach relying only upon SystemC hardware modeling and transaction level modeling abstractions (TLM) for communications. To simulate processors at reasonably high speed, SimSoC integrates instruction set simulators (ISS) as SystemC modules with TLM interfaces to the other platform components. The ISS's use a variant approach of dynamic translation to run binary code. The paper describes the overall architecture of the SimSoC full system simulator, a description ...

In transaction-level modeling (TLM), verification methodologies based on transactions allow testbenches, properties, and IP cores in mixed TL-RTL designs to be reused. However, no papers in the literature analyze the effectiveness of transaction-based verification (TBV) in comparison to the more traditional RTL approach. The first contribution of this article is the introduction of a functional-fault-model-based methodology for demonstrating the effectiveness
