In medicine, neural networks have been applied widely in medical diagnosis, detection and evaluation of new drugs and treatment cost estimation. In addition, neural networks have begin practice in data mining strategies for the aim of prediction, knowledge discovery. This paper will present the application of neural networks for the prediction and analysis of antitubercular activity of Oxazolines and Oxazoles derivatives. This study presents techniques based on the development of Single hidden layer neural network (SHLFFNN), Gradient Descent Back propagation neural network (GDBPNN), Gradient Descent Back propagation with momentum neural network (GDBPMNN), Back propagation with Weight decay neural network (BPWDNN) and Quantile regression neural network (QRNN) of artificial neural network (ANN) models Here, we comparatively evaluate the performance of five neural network techniques. The evaluation of the efficiency of each model by ways of benchmark experiments is an accepted application. Cross-validation and resampling techniques are commonly used to derive point estimates of the performances which are compared to identify methods with good properties. Predictive accuracy was evaluated using the root mean squared error (RMSE), Coefficient determination(R2), mean absolute error(MAE), mean percentage error(MPE) and relative square error(RSE). We found that all five neural network models were able to produce feasible models. QRNN model is outperforms with all statistical tests amongst other four models.

However these have been more successful in text mining and in extraction techniques used in the web. Concept mining has become increasingly popular in the research and application areas of Computer Science. This paper attempts to demonstrate the limited usage of term frequency and inverse document frequency for the application of weighting calculations for ranking documents that are based on concept quantifications. The case study considered for experiment in this paper, is based on concept terms of David Merrill’s First Principles of Instruction (FPI). Merrill’s FPI applies cognitive structures explicitly for analyzing instructional materials. Therefore it is justified that the terms categorized under each cognitive structure (or portrayal) of FPI can be taken as respective concept of that portrayal. As question papers are representative of cognitive structures in a more clear and logical way, four question papers on ‘C Language’ have been considered for the experimental study, that are detailed in this paper. Manual method has been adopted for the computation of quantities of portrayals in selected documents for the purpose of comparative study. As manual method is accurate, the values (results) are considered as benchmark values. These benchmark values are considered for comparing with normalized term frequencies that are derived (experimented) from automated extractions from the same selected documents. The study is however limited to four documents only. Conclusions are drawn from this experimental study, which will be of immense use to concept mining researchers as well as for instructional designers.

Both e-learning and knowledge management feed off the same root: learning, improved capacity to perform work tasks, ability to make effective decisions, and positively impact the world around us. The difference between KM and e-learning is a function of time; knowledge management is dynamic, e-learning is static. As a medium, e-learning allows for the sharing of knowledge that has been tested, researched and organized. Knowledge management is much livelier. Conversations and sharing understanding happens in real time. Through KM, tacit understanding can be communicated, problems can be jointly solved, and serendipitous connections are formed. KM is chaotic, current. KM is ecology; e-learning is the architecture. E-learning courses become outdated, while KM environments are continually fresh and reflective of current activity in a field. Anyway, the strengths of the two fields need to be brought together. KM should feed into e-learning in order for the content of the "course" to remain fresh and to tap learners into a sustained knowledge environment after the course is done and e-learning should feed into the KM environment to provide easy mechanisms for organizing information in the manner that most of the people function. There‟s no doubt that converging this two technology creates bigger impact in the learning process, but our discussion is focused to justify whether the convergence creates better value or not. In the light of the discussion, the conceptual link between these two key technologies has been drawn and several related issues are discussed.

For Poverty Alleviation from the country we have to confirm cultivable land to increase the crop production for feeding the over population of the country. This paper focuses on the measurement of cultivable land for cultivation. The main purpose of this paper is to briefly describe how the GIS, Digital Mapping, Internet concepts and tools can effectively contribute in the modeling, analysis and visualization phases within an engineering or research project according to the crops by using object detection, object tracking and field mapping in Bangladesh. Through GIS mapping of the agricultural lands, the statistics can be made of how much land is cultivable and each year how much land we are losing. Mapping the cultivation land will tell us how much crop we have to import from other countries. Enabling real-time GIS analysis anytime, anywhere, the implementation of the GIS information to a wider aspect. Automation is the indicator of the modern civilizations. The system will benefit the food stock of the country according to the harvest. For this research we developed a new interactive system. The system will integrate with GIS project data in Google Earth, first finds highly accurate cluster images and partial images, obtains user feedback to merge or correct these digests, and then the supplementary visual analysis complete the partitioning of the data. This study was conducted at the software laboratory, Computer Science and Engineering department, Jahangirnagar University, Dhaka, Bangladesh in 2013.

OCR performs the recognition of the text in the scanned document image and converts it into editable form. The OCR process can have several stages like preprocessing, segmentation, recognition and post processing. The preprocessing stage is a crucial stage for the success of OCR, which mainly deals with noise removal. In the present paper, a modified technique for noise removal named as “K-Algorithm” has been proposed, which has two stages as filtering and binarization. The proposed technique shows improvised results in comparison to median filtering technique.

This study examines the cashless economic system so as to assess its feasibility in Nigeria with regards to timeless, preparedness and adequacy against the backdrop of our level of development both technologically and educationally. Nigeria has continued to evolve in different realms. The economy is being reformed, the institutions are being reshaped and laws are being re-examined so as to reposition the nation to take its rightful position in the international community. As a way of fasttracking the Nigerian economy so as to be among the first 20 world economies come 2020, Nigeria proposed 2012 for the adoption of the cashless economy system starting with Lagos State but could not realized its objective. The study used structured questionnaire as a means of data collection and the collected data were analyzed using simple percentage procedure. The results indicate that: majority of Nigerians are already aware of the policy and majority agree that the policy will help fight against corruption/money laundering and reduce the risk of carrying cash and can also foster economic growth. Major problems envisaged that can hinder the implementation of the policy are: cyber fraud, limited point of sales and numeracy illiteracy. Based on the findings some recommendations made are: the government should adopt a different strategy to educate the non-literate Nigerians about the cashless economy; and the Federal Government of Nigerian should establish a Cybercrime law.

Image Fusion is to integrate complementary and redundant information from multiple images of the same scene to create a single composite image that contains all the important features of the original images. The resulting fused image will thus be more suitable for human and machine perception or for further image processing tasks. The existing fusion techniques based on either direct operation on pixels or segments fail to produce fused images of the required quality and are mostly application based. The existing segmentation algorithms become complicated and time consuming when multiple images are to be fused. A new method of segmenting and fusion of gray scale images adopting Self organizing Feature Maps(SOM) is proposed in this paper. The Self Organizing Feature Maps is adopted to produce multiple slices of the source and reference images based on various combination of gray scale and can dynamically fused depending on the application. The proposed technique is adopted and analyzed for fusion of multiple images. The technique is robust in the sense that there will be no loss in information due to the property of Self Organizing Feature Maps; noise removal in the source images done during processing stage and fusion of multiple images is dynamically done to get the desired results. Experimental results demonstrate that, for the quality multifocus image fusion, the proposed method performs better than some popular image fusion methods in both subjective and objective qualities.

We suggest improvements to the existing C4.5 decision tree algorithm. In this paper attribute oriented induction (AOI) and relevance analysis are incorporated with concept hierarchy’s knowledge and HeightBalancePriority algorithm for construction of decision tree along with Multi level mining. The assignment of priorities to attributes is done by evaluating information entropy, at different levels of abstraction for building decision tree using HeightBalancePriority algorithm. Modified DMQL queries are used to understand and explore the shortcomings of the decision trees generated by C4.5 classifier for education dataset and the results are compared with the proposed approach.

The features include ability to monitor a patient’s temperature on a continuous basis while displaying the instant result on a Liquid Crystal Display (LCD) device. The temperature monitored is logged in a memory device, Electrically Erasable Programmable Read Only Memory (EEPROM), located in the system at every 10 minutes interval and can be interfaced with a computer using USB or RS232 UART device. An ATmega16 AVR is used as the heart of the control and coordination of all the activities of the individual modules. It allowed a doctor at location from the patient to keep track of his patient’s condition while attending to other issues.

Many considerations factoring into the optimal design for such a system, including the accuracy of location, the extent of the sensor coverage, and the number and size of the sensors used. In this paper, we frame the problem by providing several definitions for sensor coverage and spatial probability for the general case, with special attention to sensor arrays in one dimension as a simplification for the purpose of clarity. We then propose a metric for measuring the overall the utility of a given set of choices that may be used in any algorithm for seeking an optimal outcome by maximizing this utility. Finally, we perform a numerical analysis of several variations of the the proposed metric, again in one dimensions, to illustrate its fitness for the task.

Today’s internet routing mainly concentrates on controlling the ingress and egress traffic which occurs through border routers. There are different ways by which we can control the traffic between autonomous systems. In most cases redistribution communities are used for the control over traffic engineering. In this paper we focus on alternative approaches like Multi Protocol Label Switching (MPLS) and Ambient Networks, through which there can be an effective control over traffic engineering. Ambient Networks are designed to solve switching problems between heterogeneous networks.

Experimental results demonstrate that, for the quality multifocus image fusion, the proposed method performs better than some popular image fusion methods in both subjective and objective qualities.

We suggest improvements to the existing C4.5 decision tree algorithm. In this paper attribute oriented induction (AOI) and relevance analysis are incorporated with concept hierarchy’s knowledge and HeightBalancePriority algorithm for construction of decision tree along with Multi level mining. The assignment of priorities to attributes is done by evaluating information entropy, at different levels of abstraction for building decision tree using HeightBalancePriority algorithm. Modified DMQL queries are used to understand and explore the shortcomings of the decision trees generated by C4.5 classifier for education dataset and the results are compared with the proposed approach.

The features include ability to monitor a patient’s temperature on a continuous basis while displaying the instant result on a Liquid Crystal Display (LCD) device. The temperature monitored is logged in a memory device, Electrically Erasable Programmable Read Only Memory (EEPROM), located in the system at every 10 minutes interval and can be interfaced with a computer using USB or RS232 UART device. An ATmega16 AVR is used as the heart of the control and coordination of all the activities of the individual modules. It allowed a doctor at location from the patient to keep track of his patient’s condition while attending to other issues.

Many considerations factoring into the optimal design for such a system, including the accuracy of location, the extent of the sensor coverage, and the number and size of the sensors used. In this paper, we frame the problem by providing several definitions for sensor coverage and spatial probability for the general case, with special attention to sensor arrays in one dimension as a simplification for the purpose of clarity. We then propose a metric for measuring the overall the utility of a given set of choices that may be used in any algorithm for seeking an optimal outcome by maximizing this utility. Finally, we perform a numerical analysis of several variations of the the proposed metric, again in one dimensions, to illustrate its fitness for the task.

Image Fusion is to integrate complementary and redundant information from multiple images of the same scene to create a single composite image that contains all the important features of the original images. The resulting fused image will thus be more suitable for human and machine perception or for further image processing tasks. The existing fusion techniques based on either direct operation on pixels or segments fail to produce fused images of the required quality and are mostly application based. The existing segmentation algorithms become complicated and time consuming when multiple images are to be fused. A new method of segmenting and fusion of gray scale images adopting Self organizing Feature Maps(SOM) is proposed in this paper. The Self Organizing Feature Maps is adopted to produce multiple slices of the source and reference images based on various combination of gray scale and can dynamically fused depending on the application. The proposed technique is adopted and analyzed for fusion of multiple images. The technique is robust in the sense that there will be no loss in information due to the property of Self Organizing Feature Maps; noise removal in the source images done during processing stage and fusion of multiple images is dynamically done to get the desired results. Experimental results demonstrate that, for the quality multifocus image fusion, the proposed method performs better than some popular image fusion methods in both subjective and objective qualities.

Today’s world power division plays an important role in wireless application areas such as base stations, antenna arrays, handheld devices etc., Here micro strip patch antenna is implemented with FR4 as a substrate material due to its benefits such as low loss and low fabrication cost while the ground material is aluminium due to its conductivity. For a good system, the return loss should be highly desirable and insertion loss should be low. Our proposed system is designed with a combination of micro strip patch antenna, leakage cancellation circuit and Gysel power divider produces equal power division with low loss such as insertion loss is measured as -39.291dB, return loss as -16.11dB and leakage cancellation as 6dB which was designed and simulated in Agilent Advanced Design System software (2009).

Today’s internet routing mainly concentrates on controlling the ingress and egress traffic which occurs through border routers. There are different ways by which we can control the traffic between autonomous systems. In most cases redistribution communities are used for the control over traffic engineering. In this paper we focus on alternative approaches like Multi Protocol Label Switching (MPLS) and Ambient Networks, through which there can be an effective control over traffic engineering. Ambient Networks are designed to solve switching problems between heterogeneous networks.
