Software testing is an important but expensive process because about fifty percent of the total development cost is spent for it. However, this part is the first one to miss by software developers if there is a limited time to complete the project. Tests are commonly generated from program source code, graphical models of software (such as control flow graphs), and specifications/requirements. Creating test cases manually is a huge work for software developers. It is time consuming and error prone. A solution which automatically generates test cases and test data can help the software developers to create test cases from software designs/models in early stage of the software development (before coding). High quality software cannot be done without high quality testing. Heuristic techniques can be applied for creating quality test data. A fault is defined as a textual problem with the code resulting from a mental mistake by the programmer or designer. A fault is also called a defect. Fault-based testing refers to the collection of information on whether classes of software faults (or defects) exist in a program. Since testing can only prove the existence of errors and not their absence, this testing approach is a very sound one. In this paper we describe the methods for evaluating the fault, methods for characterizing faults.Keywords

The purpose of this paper is to build vehicle number plate recognition for intelligent transport system. Number plate localization and recognition is an image processing technology used to identify vehicle by the number plates. that follows the RTO standards. This system is based on image capturing of the particular vehicle whose number plate is to be localized. Then segment the number plate and recognize each character of the number plate from the image by comparing it with standard RTO template emphasized by the government. .Thus the number plate of the vehicle is obtained. This very special technique finds use in social applications like tracking out the vehicle that violates the traffic rules on roads, violating the parking rules and checking at the toll-gates.Keywords

Cancer is increasingly threatening to be one of the major health problems. The degree of malignancy of a cancer is based upon the capacity of the cancer cells to metastasize. A metastasis is a neoplastic lesion arising from another cancer, with which it is no longer in contiguity. By determining the presence of early metastatic disease, treatment can often be designed, which can increase the chance for cure or delay the development of symptoms even if cure is not achievable.- Criminal Investigation

Datamining is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. It is an interdisciplinary subfield of computer science. The whole goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. Aside from the raw study step, it involves database and data management aspects, data pre-processing, model and inference thoughts, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating Data mining is the analysis step of the knowledge discovery in databases" process. Their relationships with criminals. The high volume of crime datasets and also the complexity of relationships between these kinds of data have made criminology an appropriate field for applying data mining techniques. Identifying crime characteristics is the first step for developing further analysis. The knowledge that is gained from data mining approaches is a very useful tool which can help and support police forces. An approach based on data mining techniques is discussed in this paper to extract important entities police narrative reports which are written in plain text. By using this approach, crime data can be automatically entered into a database, in law enforcement agencies. We have also applied a SOM clustering method in the scope of crime analysis and finally we will use the clustering results in order to perform crime matching process.

In the current article, an azo dye adsorbent was prepared by using Parthenium flowers activated carbon (PFAC). Sulphuric acid (H2SO4) was utilized as an activator for the preparation of activated carbon from a biomass solid waste, parthenium flowers. The sulphuric acid-treated activated carbon (PFAC) was used as low-cost adsorbent for the removal of Eriochrom black-T (EBT) azo dye from aqueous solution. The prepared activated carbon was characterized by Fourier transform infrared spectroscopy (FT-IR) before and after the adsorption process and scanning electron microscopy (SEM). A FT-IR spectrum the various functional groups present in the PFAC. SEM micrographs show the rough and irregular along with heterogeneous cavities that well distributed across the PFAC surface. Morphology of the product which is irregular shape and uniformly distributed. Adsorption property of PFAC against EBT was examined by considering the dosage effect, effect of pH, stirring time and varying concentration. At neutral pH, 10 ppm EBT azo dye aqueous solution adsorbed on PFAC (92%). Batch adsorption and regeneration studies were studied.Keywords

The engineering students of today unlike their peers have easy access to abundant subject related information from multiple internet based secondary sources such as articles, journals and so on. This abundance in information availability most often leads to confusion in the young minds and will need assistance from their teachers to act as their mentors to provide direction in order to consume data in an orderly and selective fashion and thus Activity based learning comes to rescue.Activity based learning has been around for quite some time in the education industry now. With technology enhancements made accessible and the digital media explosion causing the Internet to be readily available, the evolution of the activity based learning techniques have started to evolve at a greater pace recently.
Support for entrepreneurship has never been more important than it is now [1]. The recent times in India has also seen a splurge in the number of entrepreneurs starting their own enterprises resulting in a startup growth. Add to this the government initiatives to promote this culture, India is now the world's biggest startup ecosystem. The resultant is that the younger generation is growing curious of the term entrepreneurship and would want to get a taste of it before their enthusiasm runs down. This paper is a perfect reflection of the current market trends and the mood of the younger generation combined together to facilitate a platform for the students to plan their future appropriately.

Botanical biopesticides are alternative to hazardous synthetic insecticides. In the present study neem oil based nanoemulsion was synthesized using neem oil and tween 80. The particle size was estimated as 159.2 nm. The emulsion was characterized using particle size analyzer and TEM to confirm the formation of nano emulsion of neem oil. Trichogramma chilonis (Ishii) is an effective egg parasitoid of lepidopterous pests. It controls pests in eggs stage prior to its damaging to crops. The parasitoid is vulnerable to insecticides or oil sprays applied to the crops. The present study revealed the effects of neem nanoemulsion with T. chilonis under the controlled laboratory conditions. Different concentrations i.e., 50, 100, 500, 1000, 5000, 10000 ppm were tested on T. chilonis. The biological effects viz., per cent parasitism, adult emergence were found significantly reduced and increased mortality in all the concentrations of macroemulsion of neem oil (66.78 ± 0.50, 71.69± 1.02; 48.45 ± 0.35, 52.26 ± 0.60; 31.75 ± 0.35, 26.00 ± 0.39 in 10000 and 5000 ppm, respectively) as compared with nanoemulsion (75.40 ± 0.03, 78.26 ± 0.29; 52.50 ± 0.52, 57.85 ± 0.60; 19.57 ± 0.27, 16.25 ± 0.25 in 10000 and 5000 ppm, respectively and control (88.00 ± 0.12; 82.00 ± 1.26; 2.25 ± 0.02, respectively). These studies showed that the 10000 and 5000 ppm concentrations of nanoemulsion of neem oil were found less toxic to T. chilonis.Keywords
