Electrical discharge machining (EDM) is one of the earliest non-traditional machining processes. EDM process is based on thermoelectric energy between the work piece and an electrode. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporising. The electrode and the work piece must have electrical conductivity in order to generate the spark. There are various types of products which can be produced using EDM such as dies and moulds. Parts of aerospace, automotive industry and surgical components can be finished by EDM. This paper reviews the research trends in EDM on ultrasonic vibration, dry EDM machining, EDM with powder additives, EDM in water and modeling technique in predicting EDM performances.

A review on current research trends in electrical discharge machining (EDM)

Phosphorus is an important plant nutrient which is in short supply in many agricultural soils Because much of the soluble phosphate (P) applied to soils as fertilizer is “fixed” by the soil and rendered less available to plants, the long-term application of P fertilizers has resulted in an accumulation of total soil P, most of which is poorly soluble Many soil fungi, predominantly of the genera Aspergillus and Penicillium , have been shown to possess the ability to solubilize sparingly soluble phosphates in vitro by secreting inorganic or organic acids Growth promotion and increased uptake of P by plants inoculated with P-solubilizing fungi have also been reported by many investigators

Regular physical activity (PA) is associated with significant physiological health benefits for all individuals where various objective and subjective tools were used for evaluating PA. The aimed of this study is to access individual muscle activation and its relationship with their daily physical activity characteristics. A total of seven male subjects voluntarily participated in this study. Physical activity of each individual was derived from long, self-administered International Physical Activity Questionnaire (IPAQ) while the muscle activation was recorded from vastus lateralis muscle using wireless electromyography (EMG) system. Each subjects are required to perform maximum voluntary contraction of knee extension exercise. Both time domain features; root mean square and frequency domain features; mean frequency, median frequency were extracted from the raw EMG signals and its relationship was compared with MET-min/week scores obtained from IPAQ using Pearson correlation analysis. Regression line was also been plotted in order to observe the EMG muscle activation pattern. Overall, root mean square value showed the best correlation between IPAQ data and EMG muscle activation data. Different muscle activation pattern can also been observed between time and frequency domain features, where time domain feature which is RMS showed decreasing trend of muscle activation with the increasing of PA. This findings suggest that overall physical activity scores were moderately correlated with some EMG features, thus further attention should be given when only relying on IPAQ to classify active or inactive individual.
