In this paper, we proposed a weighting factor estimation method for peak-to-average power ratio (PAPR) based on Taguchi-genetic algorithm (TGA) in an orthogonal frequency division multiplexing (OFDM) systems. Partial transmit sequences (PTS) is one of the most attractive schemes to reduce the PAPR in OFDM systems. However, the conventional PTS scheme requires an exhaustive searching over all co...

This study discusses the application of microwave-based heating for the pretreatment of biomass material, with Pennisetum purpureum selected for pretreatment. The Taguchi method was used to plan optimization experiments for the pretreatment parameter levels, and to measure the dynamic responses. With a low number of experiments, this study analyzed and determined a parameter combination in whic...

When designing any type of fuzzy rule based system, considerable effort is placed in identifying the correct number of fuzzy sets and the fine tuning of the corresponding membership functions. Once a rule base has been formulated a fuzzy inference strategy must be applied in order to combine grades of membership. Considerable time and effort is spent trying to determine the number of fuzzy sets...

The goal of this paper is to perform complex assembly tasks, using a robot assisted by a multi-axis vibrator that reduces friction and avoids jamming. An experimentbased approach using the Taguchi Method is applied to the tuning of the vibrator. The vibrators are tuned so that effects of friction and stick-slip can be minimized. Using actual assembly data and an experimental analysis method, ca...

In this paper we present the application of a particular neuro-fuzzy system, named KERNEL, to the problem of differential diagnosis of erythematosquamous diseases, which represents a major problem in dermatology. A multistep learning strategy is adopted to obtain, starting directly from available data, a fuzzy rule base that can be used to identify the particular disease. The obtained classific...

In the recent past, demand for multifunctional and lightweight materials have increased steadily creating an increase in Hybrid polymer matrix composite which consists multiple fibers conventional resins. this study, a hybrid comprising of two reinforcements - natural silk fiber E-Glass Epoxy resin is partially eco-friendly has been fabricated effect drilling, by using 8 facet solid carbide dri...

Nodes in sensor networks can be easily compromised by an adversary due to hostile environments in which compromised nodes could be used to inject false reports into the network. The dynamic en-route scheme can detect and drop such false reports during the forwarding phase. In this scheme, choosing a threshold value is important as this gives a trade off between security of power and energy cons...

We present PROFIT, an advanced prototype system developed to estimate residential property values for real estate transactions. The system enhances Case-Based Reasoning (CBR) techniques with fuzzy predicates expressing preferences in determining similarities between subject and comparable properties. These similarities guide the selection and aggregation process, leading to the final property v...
