The workflow paradigm is advancing the scope of process modelling by supporting complex control flows, rich process structures, and the integration of heterogeneous and legacy systems. However, studies of the paradigm have been seriously hindered by the lack of a concrete framework. In order to improve understanding of the paradigm, enable studying of interaction between different features, and...

A holographic device is under development that aims to improve light collection in solar cells. The aim is to explore the potential of using photopolymer holographic optical elements (HOEs) to collect light from a moving source, such as the sun, and redirect it for concentration by a holographic lens. A working range of 45° is targeted for such a device to be useful in solar applications withou...

a research was conducted to evaluate cassava production by women farmers in igbo-eze north local government area of enugu state, nigeria. one hundred and twenty smallholder female cassava farmers were selected using multi-stage sampling. data were collected from the respondents using questionnaire and interview schedule. then descriptive statistics (mean, frequency and percentage) were used in ...

Schedulability analysis of fixed priority preemptive scheduled systems can be performed by calculating the worst-case response-time of the involved processes. The system is deemed schedulable if the calculated responsetime for each process is less than its corresponding deadline. It is desirable that the Response-Time Analysis (RTA) can be efficiently performed. This is particularly important i...

Consider a quantum computer in combination with a binary oracle of domain size N . It is shown how N/2 + √ N calls to the oracle are sufficient to guess the whole content of the oracle (being an N bit string) with probability greater than 95%. This contrasts the power of classical computers which would require N calls to achieve the same task. From this result it follows that any function with ...

In order to make software applications simpler to write and easier to maintain, a software digital signal processing library that performs essential signal and image processing functions is an important part of every DSP developer’s toolset. In general, such a library provides high-level interface and mechanisms, therefore developers only need to known how to use algorithm, not the details of h...

Background: Glucocorticoids (GC) are currently recommended as bridging therapy in combination with csDMARDs rheumatoid arthritis (RA) and should be tapered rapidly clinically feasible for safety concerns about their long-term use [1-3]. Objectives: To unravel the dynamical trajectory characteristics of GCs tapering discontinuation RA patients commencing concomitant csDMARDs. Methods: We used da...

We consider the parametric minimum spanning tree problem, in which we are given a graph with edge weights that are linear functions of a parameter λ and wish to compute the sequence of minimum spanning trees generated as λ varies. We also consider the kinetic minimum spanning tree problem, in which λ represents time and the graph is subject in addition to changes such as edge insertions, deleti...
