Clinical evaluation of nasal lacrimal sac positioning using nasal endoscope guided by intra-lacrimal duct fiber optics
This study aims to evaluate the safety and effectiveness of a new approach to locate lacrimal sac using nasal endoscopy guided by intra-lacrimal duct fiber optics during nasolacrimal ostomy. 31 patients with recurrent dacryocystitis were chosen for nasolacrimal ostomy using nasal endoscope. During the surgery, fiber optic was inserted into lacrimal duct to project the light through the lacrimal sac, subsequently...

Prediction of evaporation in tropical climate using artificial neural network and climate based models
Malaysia is a tropical country with high rainfall rate. But there is increasing demand on water due to development. Also, global weather change makes the dry season longer and evaporation rate from impounding reservoirs higher. So, evaporation as a natural phenomenon contributes in reducing the availability of water for various uses. Estimation of evaporation can give an idea about the water losses from storage...

Performance measurement systems for green supply chains using modified balanced score card and analytical hierarchical process
Environmental management is becoming a key strategic issue for Supply chain performance. Performance measurement systems for green supply chain is critical for its monitoring, control and improvement. A comparative analysis of some most widely cited Performance measurement systems for supply chains have been undertaken, and it indicates that the modified Balanced score card is a suitable framework for Green supply chain...

Experimental investigation of natural convection heat transfer of the fin arrangement on a computer heat sink
Needs for buoyancy driven ventilation appear in a variety of engineering applications, ranging from cooling of electronic components to cooling of nuclear reactor fuel elements. Hence, it becomes crucial to optimize the natural convection heat transfer as far as possible. If the fins are properly designed, they become very attractive for these applications since they offer an economical, trouble-free solution to the...

Meditation is the traditional eastern method to improve health. Leg crossing is the main component on meditation to enhance the inner chi circulation. In this study, leg crossing effects was investigated with physiological parameters for meditation group. Five minute heart rate variability (HRV) and pulse transit time (PTT) was measured as feature for leg crossing. College students were recruited as subjects. There were...

Estimation of the Rayleigh distribution parameters with presence of k outliers generated from Gamma distribution
The moment, maximum likelihood and mixture of the estimators of parameters of the Rayleigh distribution are derived with presence of k outliers generated from Gamma distribution. These estimators are compared empirically when all the parameters are unknown; their Bias and MSE are investigated with the help of numerical technique. We have shown that these estimators are asymptotically unbiased. At the end, we conclude...
