Brushless Direct Current (BLDC) motors are one of the motor types rapidly gaining popularity. BLDC motors are used in industries such as Appliances, Automotive, Aerospace, Consumer, Medical, Industrial Automation Equipment and Instrumentation. As the name implies, BLDC motors do not use brushes for commutation; Instead, they are electronically commutated. This paper is focused on the various methods of testing and various tests both during construction and after construction is done on BLDC motors. These tests include: measurement of coil resistance, measurement of air gap, vibration testing, magnetic saturation, temperature experiments and etc. For a large number of experiments, The proposed method has been described for the size and various types of BLDC motors that in different conditions the motor is encountered.

Web 2.0 has become principle tool for accessing information. With Photo sharing websites like Flickr, Picassa, Zoomr images uploaded by user and their tags are available. But Missing tags and Noise problems among image and tag make it difficult to retrieve relevant image based on user’s preference. This requires tags refinement. We propose a model that utilizes Ranking based multicorrelation tensor factorization model for enriching tags pool. This model does it by constructing ternary relation between User, Image and Tag. RMTF does qualitative analysis on available tag set and find positive example and negative example by finding user, image tag interrelations. Tags are compared based on context relevance and semantic relevance. The proposed model finds better result than previous solutions. Given module is tested for multiple word query and shown attractive results.

ABSTRACT Suitability of growing media or substrates is essential for production of quality seedlings for transplant. It directly affects the development and later maintenance of the extensive functional system. A good growing medium would provide sufficient anchorage of support to plant, serves a reservoir for nutrient and water, allow oxygen diffusion to the root and permit gaseous exchange between the root and atmosphere outside the root substrate. In the present of study different growth media were used to germinate the seed of white yam (Dioscorea rotundata) under a controlled growth chamber to identify which among the tried media is best for yam seed. The growth media tested were Cocopeat, Peat pellet, Carbonized rice husk, Top soil, Cocopeat + Top soil and Carbonized rice husk + Top soil. Each treatment was measured into a nursery seedling basket, arranged in randomized complete block design, and replicated four times. Daily minimum and maximum Temperature and Relative humidity records were recorded throughout the experiment. At 60 and 90 days after seed sowing, growth response parameters were recorded and were subjected to analysis of variance and treatment means were separated using least significant difference at 5% probability level. Highest germination of 71.65 and 88.65% at 60 and 90 days after sowing respectively were recorded from yam seed planted in Cocopeat and the same trend was observed in respect of growth response parameters observed. Top soil had the least influence as growth medium, which was not significantly different from response from its mixture with other growth media.

CHROMagar Candida is a new differential culture medium that allows the isolation and presumptive identification of species of yeast of clinical importance. During the past two decades, there has been a significant increase in the prevalence of fungal infections caused by Candida species. The aim of the study was to isolate and identify Candida species from the oral cavity with CHROMagar Candida. This study was carried out in 30 patients with infections aged 21 to 90 years. Swabs samples were taken from oral cavity and were cultured directly on Sabouraud dextrose agar medium. In this study shows that CHROMagar Candida can easily identify four species of Candida on the basis of colonial color and morphology, and accurately differentiate between them i.e. Candida albicans, Candida glabrata, Candida tropicalis and Candida krusei. Results showed the prevalence of C.albicans (n = 21, 70%), C. glabrata (n = 5, 16.6%), C. krusei (n = 2, 6.7%), and C. tropicalis (n =2, 6.7%). In this investigation, CHROMagar produced light green colonies and were considered as Candida albicans, Pink with a darker mauve center colonies were identified as Candida glabrata, pink with pale borders colonies were identified as Candida krusei, and dark blue, purple diffusion colonies were identified as Candida tropicalis. CHROMagar is extremely useful in making a rapid presumptive identification of common yeast species. This capability plus the ability to detect mixed cultures of Candida species promises to improve and streamline the work flow in the mycology and clinical microbiology laboratory.

This paper describes a hybrid design for intrusion detection that combines anomaly detection with misuse detection. The proposed method includes an ensemble feature selecting classifier and a data mining classifier. The former consists of four classifiers using different sets of features and each of them employs a machine learning algorithm named fuzzy belief k-NN classification algorithm. The latter applies data mining technique to automatically extract computer users’ normal behavior from training network traffic data. The outputs of ensemble feature selecting classifier and data mining classifier are then fused together to get the final decision. The experimental results indicate that hybrid approach effectively generates a more accurate intrusion detection model on detecting both normal usages and malicious activities.

Recently, the focus of scientific investigations has moved from the primary role of food as the source of energy and body-forming substances to the more subtle action of biologically active food components on human health. There has been an explosion of consumer interest in the active role of food in the well-being and life prolongation, as well as in the prevention of initiation, promotion, and development of non-transmissible chronic diseases. As a result, a new term—functional food—was proposed. Among these foods, probiotics exert positive effects on the composition of gut micro biota and overall health, and the market is increasing annually. In the current study the probiotic bacterium Lactobacillus acidophilus was encapsulated in microcapsules of sodium alginate. These encapsulated microbes were used in the fermentation and production of curd with high nutritional values. On comparing the curd fermented with microencapsulated bacterium with that of the non-encapsulated forms (traditional fermentation technique) it was found out that there was a considerable reduction in the fat content of the sample prepared with the microencapsulated form (2.20 gm) to the non-encapsulated organisms (3.90 gm). The protein and the vitamin-C content were found to be more or less the same in both the cases. The iron content of the sample prepared with microencapsulated form was found to be 7.2 gm to 3 gm of iron content for the sample produced through non-encapsulated bacterium. It was found out that the curd fermented through the microencapsulated L. acidophilus was found to be nutritionally rich and that the organism could also act survive as a probiotic in the gut in the presence of a protective microencapsulation.
