I'm a Senior Lecturer at the Robert Gordon University experienced researcher in the areas of environmental design, Energy performance in the Built Environment and visualisation. My work has been widely published and acknowledged nationally and internationally through awards the Scottish Saltire award for Innovation in Housing, the International Award for Innovation and Research from CIOB, Scottish Energy Efficiency Award. I keep strengthening the connection between my research and teaching.

Modeling of a communication chain components & principles of simulation in the scilab/scicos environment

Proceedings of 2005 IEEE Conference on Control Applications, 2005. CCA 2005.

Models of basic components are introduced in the Scilab Connected Object Simulator (SCICOS) package. A Scicos diagram of a single-user system is realized and time domain and parametric simulations are developed in order to compute the bit error rate of the transmission. Principles of simulation of the realized diagram using the parallel virtual machine toolbox are then given

Main hypothesis is computed tomography (CT)derived AS bulging and ventricular septum (VS) bowing signs would be used to identify patients with acute pulmonary embolism (PE) and significant hemodynamic derangements. Methods: In the prospective registry, 221 consecutive patients with a first episode of acute PE diagnosed by chest CTwere grouped by clinical hemodynamic assessment: massive or submassive PE (Group 1), and small PE (Group 2). The curvatures of the AS and VS, right ventricle (RV) and left ventricle (LV) diameters were measured on chest CT. Results: Group 1 showed higher degrees of RV dilatation, and abnormal VS and AS curvatures versus Group2. The sensitivity and specificity of a CT-derived RVD/LVD ratio .0.9 for predicting PE with clinically significant RV dysfunction were 60.8% and 69.7%, respectively. An abnormal VS bowing sign was observed in 33 (32.4%) and 7 (5.9%) patients in Groups 1 and 2, respectively (p,0.001). An abnormal AS bulging sign was observed in 62 (60.8%) and 35 (29.4%) patients in Groups 1 and 2, respectively (p,0.001). On the basis of the CT-derived RVD/LVD ratio, VS bowing, and AS bulging status, patients with acute PE were classified into three risk groups: higher risk, lower risk, and intermediate risk. An algorithm was designed to predict clinically significant hemodynamic abnormality based on these signs (Figure); patients deemed "higher risk" exhibited higher 90-day allcause mortality than patients in the lower-risk group (p=0.028). Conclusions: Conventional chest CT-derived hemodynamic findings, including abnormal AS and VS signs, can be used to identify high-risk patients with acute PE and to predict early mortality.
