İş taleplerinin, çalışanların yeteneklerini aşmamasını sağlamak ve bir işi gün boyu yapabilecek düzeyde tutmak ergonomi alanında sorumluluğu hedefidir. Sürekli performans sınırının üzerinde iş yapması beklenen çalışan yorulur. Yorgunluk; verimi, sağlığı, güvenliği psikolojik dengesi açısından olumsuz etkiler yaratabilmektedir. Metabolik enerji harcama hızı, aşırı miktarda fiziksel yorgunluk bir...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

We used functional magnetic resonance imaging (fMRI) to assess cortical activations associated with increasing task difficulty (TD) in a visuospatial paired associates learning task. Encoding and retrieval were examined when 100% successful retrieval of three, four, or six object-location pairs had been attained (thus ensuring that performance was matched across subjects). As memory load increa...

This paper presents the modelling of an autonomous amphibious vehicle developed at the Australian Centre for Field Robotics, Sydney. All parts of the vehicle’s driveline from the engine, CVT, gearbox to wheels are analysed and modelled. Results from simulation, compared with data from characterising experiments, show that these models are valid and can be used for the control purpose. Keyword: ...

We describe how Total Least Squares (TLS) algorithms can be applied as a powerful and eÆcient modelling tool for wideband speech. A detailed description in both time domain and frequency domain illustrates how the modelling functions { damped sinusoids { naturally synthesise non-stationary signals. Straightforward implementations of TLS applied to fullband speech are known to be computationally...

considering the fact that rocks fail faster under tensile stress, rock tensile strength is of greatimportance in applications such as blasting, rock fragmentation, slope stability, hydraulic fracturing,caprock integrity, and geothermal energy extraction. there are two direct and indirect methods tomeasure tensile strength. since direct methods always encompass difficulties in test setup, indire...

Abstract This study presents the development, analysis and assessment of residential lighting load profile using computational intelligence based modelling Adaptive Neuro Fuzzy Inference System (ANFIS) and Neural network (NN) models for prediction (forecasting) and evaluation of lighting load and initiatives. Factors considered in the development of the models include natural lighting, occupanc...
