The achievement of different university degrees (from graduate to the specialization, master's and doctoral) usually is related to the development and presentation of research results conducted by an Academic Advisor. However, their finalization or the results may be adversely affected by the lack of identification of risk that may present themselves during the process of construction and development of the research. To minimize these impacts, the present study was based on the alignment and adjustment of processes present in the Project Management Body of Knowledge (PMBoK), a specific guide that consolidates the best practices of project management from the Project Management Institute (PMI), and the use of Failure Mode and Effects Analysis (FMEA). From such elements and the identification of factors relevant to the educational institution involved and the processes related to the advisory and development of scientific research, it was sought to build a proposed risk analysis in the academic, named Academic Project Risk Management Plan (APRMP). This aims to contribute to the discussion and gathering information that can support the Advisor and the student at all stages of the research (planning, development and conclusion) that downside risks are avoided or minimized and that opportunities become clear and effective possibilities.

We report a successful implementation of the sharedmemory parallelization using OpenMP to the dose calculation by the Monte Carlo particle and heavy-ion transport code PHITS. The OpenMP shared-memory parallelization is better suited than the MPI distributed-memory parallelization which is originally implemented in the PHITS code in the case of human voxel data which requires a large memory space. We have confirmed that the same results can be obtained with and without the shared-memory parallelization by the modified PHITS code. Sufficiently high OpenMP parallelization efficiency (92.4% with 8 parallelized cores within a single node) is achieved even when the special treatment for accessing memory to avoid memory contentions is taken into account. We implement the OpenMP parallelization on top of the MPI parallelization originally included in PHITS so that the modified code works in a hybrid way such that the distributed-memory parallelization for different nodes by MPI and the shared-memory parallelization among the cores in a single node by OpenMP. The performance has been checked on supercomputers: RICC and K computer. © 2013 Springer-Verlag.

This paper presents results of a time-domain spherical-multipole near-to-far-field transformation together with a moment expansion applied to antenna radiation patterns. The equivalence principle is applied to the tangential fields all over the FDTD/WP-PML spatial grid and the use of the spherical-multipole expansion leads to the near-to-far-field transformation, and energy and power norms of temporal signals are used to obtain the antenna radiation patterns for transient and steady-state responses. Such approach is employed to obtain UWB antenna radiated fields and radiation patterns directly in time-domain, it being more convenient to perform an unified characterization in time and frequency domains. © 2013 SBMO/SBMag.

This paper reports diffusion suppression in gel dosimetery by using nanocomposite gel. A Fricke xylenol gel (FXG) and a dichromate gel (DCG) were selected for adding a small amount of nanoclay (Laponite XLG). The diffusion coefficient and T1 distribution were evaluated by irradiating the gel dosimeter with a heavy ion beam. As a result, these gels showed improvement in the diffusion coefficient. In particular, by addition of the clay, the DCG exhibited diffusion-free characteristics. Moreover, it exhibited high stability after irradiation. © 2013 Springer-Verlag.

In this abstract, we describe provenance traces generated from executions of scientific workflows managed by the Swift parallel scripting system. They follow a provenance data model, used by MTCProv, the provenance management component of Swift. It is similar to PROV, representing most of its core concepts and including additional information about the scientific domain, computational resource consumption, and prospective provenance. We describe provenance queries that follow patterns commonly found in high performance computing and that are straightforward to support with MTCProv's built-in procedures. These queries often involve costly relational join operations and recursion, providing a relevant case for benchmarking. © 2013 Authors.

This paper proposes a two-level feature selection to improves Naïve Bayes with kernel density estimation. The performance of the proposed feature selection is evaluated on question item set based on Bloom's cognitive levels. This two-level feature selection contains of filter and wrapper based feature selection. This paper uses chi square and information gain as the filter based feature selection and forward feature selection and backward feature elimination as the wrapper based feature selection. The result shows that the two-level feature selection improves the Naïve Bayes with kernel density estimation. The combination of chi square and backward feature elimination give more optimal quality than the other combination.

Revenues and profits from short life cycle products will depend upon careful formulation and execution of production plans in response to demands in the marketplace. This research contributes to the development of the production and inventory build-up strategies for short life cycle products under different demand-supply scenarios. A modified Bass diffusion model is used to characterise the product demand pattern with consideration of demand-sales interaction. We develop cost models based on production costs, inventory carrying costs, backlog costs, and cost of lost sales for a number of different production scenarios. The optimal production rate is obtained by minimising the total cost. We also investigate the benefit of an initial build-up of inventory before the product's sales period starts. © 2013 Inderscience Enterprises Ltd.

The reliability on Safety Instrumented Systems (SIS) is critical for the safe operation of many industrial applications. In particular, SIS play an important role in oil and gas processing plants. SIS are responsible not only for the continuous operation of the plant, it also keeps the plant in a safe state, avoiding damages to the environment and minimizing risks to employees. Therefore, the correct behavior of such systems is an important goal to achieve when building industrial plants. Verification and testing of SIS programs is a very hard task to accomplish. This happens mainly for two reasons. First, testing the real system is very expensive and sometimes it may take a huge amount of time, weeks or even months. Second, those systems deal with a huge number of variables. It is not always possible for a human tester to check if all of them are correct when performing tests. Providing an automatic and formal testing approach for such systems is an important contribution for the development of such systems. In this work we introduce a new method for generating test cases for SIS programs running on programable Logic Controller (PLC). As we did on previous work, ISA 5.2 diagrams are used as specification of the systems, but now we are using a hardware-in-the-loop technique, and the target artifact is a software running on a PLC. To avoid the execution of redundant tests, we introduced a new test case generation algorithm that is based on equivalence classes. Finally, we discussed a study case in which our method is used to detect error, that were introduced on purpose, on a simple system.

A step-based tutoring system for linear circuit analysis is being developed with the capabilities to automatically generate circuit problems with specified characteristics, including randomly generated topologies and element values. The system further generates fully-worked, error-free solutions using the methods typically taught in such classes, and accepts a rich variety of student input such as equations, matrix equations, numerical and multiple-choice answers, re-drawn circuit diagrams, and sketches of waveforms. A randomized, controlled study was conducted using paid student volunteers to compare the effectiveness of two of our tutorials in comparison to working conventional textbook-based problems. The average learning gain was only 3/100 points for the textbook users, but 29/100 points, about 10 times higher, for the tutorial users. The effect size on the post-test scores was 1.21 pooled standard deviations (Cohen d-value) and was statistically significant. A motivational survey administered to these students yielded a 0.53 point higher rating for the software than for the textbook (on a 1-5 scale). The system is being used in Spring 2013 by over 340 students in EEE 202 at Arizona State and two community colleges. About 99% of these students rated the system as “very helpful” or “somewhat helpful”.

Impact response of contact lenses is measured using the Levitation Mass Method (LMM). In the LMM, a small mass collides with contact lenses and the impact force is measured with high accuracy as the inertial force of the moving part. A pneumatic linear bearing is used to achieve linear motion with sufficiently small friction acting on the moving part. Hysteresis loop and consumed energy as mechanical characteristics of contact lenses are also calculated.. © (2015) Trans Tech Publications, Switzerland.
