MPI / OpenMP mixed mode codes could potentially offer the most effective parallelisation strategy for an SMP cluster, as well as allowing the different characteristics of both paradigms to be exploited to give the best performance on a single SMP. This paper discusses the implementation, development and performance of mixed mode MPI / OpenMP applications. The results demonstrate that this style...

We propose a new built-in self-test (BIST) method based on a combination of a pseudo-random test method with a deterministic test. This enables us to reach a high fault coverage in a short test time and with a low area overhead. The main feature of the method is that there are no memory elements to store the deterministic test patterns; the test patterns are being produced by a transformation o...

Sparse linear algebra algorithms, and especially algorithms for the iterative solution of sparse lineary systems, lie at the heart of many scientific computing applications, ranging from computational fluid dynamics to structural engineering and electromagnetic analysis. Their efficient implementation is thus a very important challenge for the numerical software community. The current trend in ...

Surveys increasingly use mixed mode data collection (e.g., combining face-to-face and web) because this controls costs and helps to maintain good response rates. However, a combination of different survey modes in one study, be it cross-sectional or longitudinal, can lead to different kinds of measurement errors. For example, respondents in a face-to-face survey or a web survey may interpret th...

A test-per-clock BIST method for combinational or full-scan circuits is proposed. The method is based on a design of a combinational block the decoder, transforming pseudo-random LFSR code words into deterministic test patterns. A Column-Matching algorithm to design the decoder is proposed. The Column-Matching method modified to support a mixed-mode BIST is proposed as well. Here the BIST is di...

A novel test-per-clock built-in self-test (BIST) equipment design method for combinational or full-scan circuits, together with necessary supplementary algorithms, is proposed in this Thesis. This method is mostly based on a design of a combinational block the Decoder, transforming pseudo-random code words into deterministic test patterns pre-computed by some ATPG tool. The Column-Matching algo...

A SIMO (single input and multiple outputs) universal mixed-mode (including voltage, current, transadmittance, and transimpedance modes) biquad with one input (a single voltage or current input) and eight outputs (five voltage outputs and three current outputs simultaneously) by using three differential difference current conveyors (DDCCs), four resistors, and two grounded capacitors, is present...

Rich News, a system that augments news broadcasts with textual content, is described. The system identifies individual stories in news broadcasts, and annotates them with related content from the World Wide Web. The web content is subsequently semantically analysed, and used to produce summary information for each news story. This content can then be delivered to users as part of an interactive...

Mixed Mode Environments (MME) [1] are environments with different dimensions of heterogeneity: heterogeneous devices, heterogeneous software, and heterogeneous communication technologies. In MME we have many different devices and there are continuously new devices developed and introduced. To deal with these different kinds of devices we as humans intuitively classify them into different types....
