This paper proposes an Artificial Neural Network approach for solving the Combined Economic and Emission Dispatch (CEED) problem using Radial Basis Function (RBF) based neural network. The purpose of CEED is to minimize both the operating fuel cost and emission level simultaneously while satisfying load demand and operational constraints. This multi-objective CEED problem is converted into a single objective function using a modified price penalty factor approach.

In this study, the realization of pitch range of tones in the context of downstep in Chinese is analyzed. The test sentences are composed of "High + Low + High + Low‟ sequences, and it is found that, compared to utterance with 2 HL sequences, the overall pitch ranges of longer utterances are great. The pitch range of the last HL sequence is the greatest, and that of the first HL sequence is the second greatest, with that near the middle of the utterance to be the least great. The pitch range of the utterance initial HL sequence of shorter utterance tends to be greater than that of longer ones, and those of the final HL sequences of long and short utterances approach a constant value.

In this work we have proposed a fully automatic algorithm to detect brain tumors by using digital image processing techniques is proposed. Here we detect the tumor, segment the tumor and calculate the area of the tumor. The complex problem of segmenting tumor in MRI can be successfully addressed by considering multi-step approaches. The tumor detection is often an essential preliminary phase to solve the segmentation problem successfully. The experiments showed good results also in complex situations. Segmentation of images embraces a significant position in the region of image processing. Tumor segmentation and area calculation from MRI data is an essential but fatigue, boring and time unbearable task when it completed manually by medical professional when evaluate with present day's high speed computing machines which facilitate us to visual study the area and position of unnecessary tissues. We use SVM classifier to classify the type of tumor.

The critical radius effect is an interesting phenomenon of heat transfer in insulated circular solids. Insulating a cylinder or sphere larger than the critical radius has the expected effect of retarding heat loss. If the radius of cylinder or sphere is smaller than the critical radius, adding insulation will actually increase heat loss. In present paper a copper cylinder is heated by means of a heater 300W 240V which heats uniformly the copper cylinder. This copper cylinder is bounded by asbestos. By heating of copper cylinder asbestos gets heated.Tappings for thermocouple are given along insulation for asbestos. Finally critical radius of insulation for a cylinder is determined.

This research has two objectives. The first objective is to study the effect of assembly process factors on the seal strength of the VRLA battery. The second objective is to find the optimal setting of significant parameters to maximize the seal strength to reduce the defective rate from air leakage defect. This research applied the design of experiment (DOE) technique using the two-level full factorial design to screen out the factors and then used the face-centered central composite design to help find the relationship between the seal strength and the significant factors. It was found that the factors which significantly affect the seal strength were the stopper distance of the case, the stopper distance of the lid, and the melting time. The optimization technique helped determine that the machine setting should be at the stopper distance of the case at 34.97 mm., the stopper distance of the lid at 77.95 mm., and the melting time at 3.1 second to maximize the heat seal strength. After improvement, the defective rate from air leakage defect significantly decreased from 0.12% to 0.01%.

Mobile ad hoc network is a col lection of wireless mobile nodes, such devices as PDAs, mobile phones, laptops etc. that are connected over a wireless medium. There is no pre-existing communication infrastructure (no access points, no base sta- tions) and the nodes can freely move and self-organize into a network topology. Hence, balancing the load in a MANET is important because the nodes in MANET have limited com- munication resources such as bandwidth, buffer space, and battery power. Most of the current routing protocols for mobile Ad-hoc net- works consider the shortest path which is having minimum hop count as optimal route without considering any partic- ular node's traffic and resulting in degradation of the per- formance by causing serious problems in any perticular mo- bile node like congestion, queuing delay and power depletion. Therefore it is very attractive to investigate Routing protocols which use a Routing Metric to Balance Load in Ad-hoc net-works. This paper discusses about LBMPR (Load balancingwith multipath Routing Protocol) for efficient data transmis- sion in MANETs.
