It is evaluated for 10-million queues on a regular HP-PC with Intel i7-860 for three different HFJ cases. The maximum time is 16 minutes, which is only about 0.01% of the full system simulation time.

Together with its supporting tool CoSBiLab KInfer for inferring kinetic parameters, BlenX provides an effective compromise between the differential equations-based and mechanisms-based approaches to modeling of pharmacodynamical systems. In this paper, we support this claim with models that describe the tumor size changes over the time course of chemotherapy in lung cancer patients treated with gemcitabine and carboplatin. Our first simple high-level model relies on a few identifiable and biologically relevant parameters. The estimation of these parameters requires only the tumor growth curve in vivo, typically available in the clinical setting. This model is an essential first step of our ongoing work where we aim at explaining the high-level behavior with our second model. This latter model incorporates the molecular machinery of the drug that determines the cytotoxic effect resulting in the shrinkage of the tumor.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121355790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implementing cellular automata on serial bases does not provide the required speed. Conventional processors can't process this enormous amount of data in a short period of time, so a new approach is required to improve computational complexity. Systolic array is a kind of parallel processing approaches which can increase the processing speed. Because processors of systolic set can work simultaneously and have its own local memory, they can improve the processing speed by limiting the number of external memory access in order to execute each of their instructions. This article studies implementing cellular automata on systolic arrays. To do so, once implementing is done by serial base, the other is done by using systolic arrays. The speed of the two methods has been compared with each other, too.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116189774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerical and simulation results presented illustrate how the performance of an ad hoc network protocol drastically changes as a result of changing the mobility model and power control system of the network. The simulation result for DSR and AODV showed a significant improvement with 86.8% decrease in end-to-end delay (sec), while AODV also showed 68.5% drop in end-to-end delay. The network load simulation result revealed that DSR protocol maintained a constant load while there was a 75%drop in routing load for AODV protocol.

The work is a first effort towards restoring natural like swing phase in paraplegic gait through a new hybrid orthosis, referred to as spring brake orthosis (SBO). This mechanism simplifies the control task and results in smooth motion and more-natural like trajectory produced by the flexion reflex for gait in spinal cord injured subjects. The study is carried out with a model of humanoid with wheel walker using the Visual Nastran (Vn4D) dynamic simulation software. Stimulated muscle model of quadriceps is developed for knee extension. Fuzzy logic control (FLC) is developed in Matlab/Simulink to regulate the muscle stimulation pulse-width required to drive FES-assisted walking gait and the computed motion is visualised in graphic animation from Vn4D and finite state control is used to control the transaction between all walking states. Finite state control (FSC) is used to control the switching of brakes, FES and spring during walking cycle.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114675668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key part of algorithm for a range measurement by POERF is the disparity estimation of images T'1 and T'2 of a target point T from the stereo pair images. Specific conditions of this task do not allow using commonly published algorithms for the solution of stereo-correspondence problem without substantial modifications. Simultaneously, readily available databases of reference stereo-pair images (as for example Middlebury Stereo Database) are not proper for requisite simulation experiments. In this regards, we were obliged to create own database -- the Catalogue of Targets (with stereo-pairs images of selected convenient objects) and an appropriate simulation testing software -- the program RAWd is. The paper deals especially with the problem of sufficiently accurate conversion of a well specified slant range DT0 of a target point T to the corresponding reference disparity value. Consequently, appropriate slant ranges DT can be associated with finding disparities in the given stereo-pair images.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"2011 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114796832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes affect the surrounding ground in the form of lateral movement which eventually impose direct strains onto nearby structures and can cause pile deviation and cracks. This study models the lateral movement in soft clay due to excavation using finite element simulation known asPLAXIS. Two types of isotropic models in PLAXIS are compared that are Hardening soil Model and Mohr Coulomb Model. The soft clay was collected from a site location in Selangor, Malaysia and the physical and engineering properties test were firstly determined. For simulation in PLAXIS, a geometry model which consists of sand and clay layer was used and a vertical sheet pile was driven downwards until bottom of the soil layer. Excavations were done in stages on one side of the soil retained induced horizontal displacement to the sheet pile until resulted failure to occur. From the results obtained, it can be concluded that Mohr-Coulomb model are almost equal to Hardening-Soil model in terms of horizontal displacements. However, for the soil stresses, the researcher found that the percentage differences between the both models are higher which is caused by characteristic of Hardening-Soil model that accounted fortress dependency of stiffness increase with pressure.","PeriodicalId":161995,"journal":{"name":"2011 UkSim 13th International Conference on Computer Modelling and Simulation","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114627336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
