This longitudinal study focuses on evaluating grade 7-9 school students’ perceptions of intervention modules intended to be relevant, as well as promoting learning attributes to raise awareness of science-related careers. Students are taught through six purposely developed and designed career-related teaching–learning modules (C-TLMs).

Ebook "Adaptive beaming and imaging in the turbulent atmosphere" due to the wide application of adaptive optical systems, an understanding of optical wave propagation in randomly inhomogeneous media has become essential, and several numerical models of individual AOS components and of efficient correction algorithms have been developed. This monograph contains detailed descriptions of the mathematical experiments that were designed and carried out during more than a decade's worth of research.

This paper presents a study to evaluate the effectiveness of auxiliary braking systems that are necessary when designing improvements for van trucks when descending hills. The results of the study show the clear effectiveness of auxiliary braking systems in different operating conditions, which provides a basis for the development and improvement of braking systems in the future.

We present new results for the theoretical prediction of doubly-polarized cross sections of W Z events at the LHC using leptonic decays. Compared to the previous studies, two new kinematic cuts are considered. These cuts are designed to enhance the doubly-longitudinal (LL) polarization and, at the same time, study the Radiation Amplitude Zero effect.

This paper presents the experimental results of structural responses of box beams using TRC. Ten specimens in two groups are designed with different longitudinal and transverse textile reinforcement ratios. All the specimens are loaded under a four-point bending test, in order to investigate both flexural and shear behaviour of TRC box beams.

To propose a paradigm for a scalable time-aware clinical data search, and to describe the design, implementation and use of a search engine realizing this paradigm. The Advanced Cohort Engine (ACE) uses a temporal query language and in-memory datastore of patient objects to provide a fast, scalable, and expressive time-aware search.

Orthotropic composite pressure vessels are designed based on considering the role of a matrix in the force balance of the structure and its leakage due to matrix failure. To be more specific, the stress and strain states of the shell are considered simultaneously in both longitudinal and transverse directions of the fiber.

Cross-sectional studies have shown that elderly with a natural dentition have better general health than edentulous elderly, but this has not been confirmed in studies with longitudinal design. This prospective longitudinal study with a follow-up of 8 years aimed to assess differences in general health, healthcare costs and dental care use between elderly with a natural dentition and edentulous elderly wearing implant-retained or conventional dentures.

In the mechanisms and machines operating at high speeds, the elastic vibration of links is inevitable. In this paper the dynamic modeling and controller design for a flexible four-bar mechanism are studied. The fully coupled non-linear equations of motion are obtained by using the Lagrange’s equations with multipliers for constrained multibody systems. The resulting differential-algebraic equations are solved using numerical methods. A simple PD controller is designed to reduce the influence of the elastic link on the desired motion.

Estimates of asthma incidence and its possible determinants in adolescent populations have rarely been obtained using prospective designs. We sought to identify socio-demographic and other patterns in the incidence of asthma among Canadian adolescents and to examine possible behavioural and environmental determinants of asthma incidence using longitudinal analyses.
