Rheological measurements of suspensions are often performed using a rotational rheometer. In this type of rheometer, the tested fluid is sheared between two surfaces, one of which is rotating to generate a laminar flow of the fluid between the surfaces (i.e., a Couette flow). Manufacturers of commercially available rheometers generally recommend the use of a standard oil of known viscosity to v...

In this thesis, we conduct an extensive case study on formally modeling, analyzing, and designing retransmission-based reliable multicast protocols. We first present an abstract model of the communication service that several reliable multicast protocols [12, 13, 32–34] strive to provide. This model precisely specifies i) what it means to be a member of the reliable multicast group, ii) which p...

Switched reluctance motors (SRM) are attracting much attention because of their special advantages. Generated heat, due to losses, can reduce the life time of SRMs. Therefore, taking into account thermal modeling helps to improve their performance and increase their life time. In this paper, a lumped thermal model of SRM based on the analogue circuit of conductive and convective thermal resista...

We use a simple carbon cycle-climate model to investigate the interactions between a selection of idealized scenarios of mitigated carbon dioxide emissions, carbon dioxide removal (CDR) and solar radiation management (SRM). Two CO(2) emissions trajectories differ by a 15-year delay in the start of mitigation activity. SRM is modelled as a reduction in incoming solar radiation that fully compens...

Switched Reluctance Motor is a rotating electric machine where both stator and rotor have salient poles. Switched Reluctance Motor (SRM) drives are gaining attention due to their extremely rugged construction and fault-tolerant capabilities, which prove that SRM drives, are highly suitable for variety of industrial applications. In this paper, FPGA based digital controllers are designed for a 6...

The paper presents a significant improvement to the implementation of the spectral relaxation method (SRM) for solving nonlinear partial differential equations that arise in the modelling of fluid flow problems. Previously the SRM utilized the spectral method to discretize derivatives in space and finite differences to discretize in time. In this work we seek to improve the performance of the S...

OBJECTIVE To compare the responsiveness of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and a questionnaire format of the Lequesne-Algofunctional Index in patients with OA of the lower extremities. METHODS Longitudinal analysis of the instruments' responsiveness [standardized response mean (SRM), effect size (ES)] in ambulatory patients undergoing hip or knee art...

The oncogenic transcription factor c-Myc (Myc) is frequently overexpressed in human cancers. Myc is known to induce or repress a large set of genes involved in cell growth and proliferation, explaining the selection for mutations in cancer that deregulate Myc expression. Inhibition of ornithine decarboxylase, an enzyme of the polyamine biosynthetic pathway and a Myc target, has been shown to be...

OBJECTIVE Millions of patients experience the disabling hand manifestations of rheumatoid arthritis (RA), yet few hand-specific instruments are validated in this population. Our objective was to assess the reliability, validity, and responsiveness of the Michigan Hand Questionnaire (MHQ) in patients with RA. METHODS At enrollment and at 6 months, 128 RA patients with severe subluxation of the...

The recent discovery of the "Stress Repair Mechanism" (SRM) enables the Unified Theory of Medicine postulated by Hans Selye. It confers cohesive theories of anesthesia, analgesia, and allostasis that enable the alteration of anesthetic technique to optimize surgical outcome. The SRM continuously maintains and repairs the vertebrate body in accord with stressful forces and stimuli. Three synergi...
