Diversity and distribution of cardinal fishes in Indian coastal waters with an occurrence report of spot fin cardinal fish Apogon queketti from Central south west coast of India
The family Apogonidae is a specious family with 346 species, in which most of them marine and some thrive in brackish water.
These are commonly referred to as cardinal fishes, which seldom reaches a maximum size of 20cm . Sixty five species of this family
have been reported from Indian waters. Apogon queketti is a valid species and two taxa have been synonymized with this viz.,
Apogonichthys queketti and Jaydia queketti. The genus Apogon which contains 108 valid species are mostly marine, living on sandy
and muddy bottom of the continental shelf
Adjustable impedance, force feedback and command language aids for telerobotics (parts 1-4 of an 8-part MIT progress report)
Projects recently completed or in progress at MIT Man-Machine Systems Laboratory are summarized. (1) A 2-part impedance network model of a single degree of freedom remote manipulation system is presented in which a human operator at the master port interacts with a task object at the slave port in a remote location is presented. (2) The extension of the predictor concept to include force feedback and dynamic modeling of the manipulator and the environment is addressed. (3) A system was constructed to infer intent from the operator's commands and the teleoperation context, and generalize this information to interpret future commands. (4) A command language system is being designed that is robust, easy to learn, and has more natural man-machine communication. A general telerobot problem selected as an important command language context is finding a collision-free path for a robot
A Bio-Crypto Protocol for Password Protection Using ECC
In information security the following security parameters like, integrity , non repudiation and confidentiality , authentication must be satisfied. To avoid thievery of organization resources it needs be secured in more efficient way and there is always demand for different levels of security attacks include virus , brute force and Eveadroper in business that organizations make use of voice biometrics an attractive low-cost. Voice biometrics is the cheapest among the other biometrics and used all levels for management to buy readily available metric and it is the way of identifying individuals remotely with high level of accuracy . In this work, we have been designed a new password- authentication approach that provides security using voice biometrics for authentication and uses the device itself into an authenticator which uses voice itself as its passwords and we are primarily interested in keys that can be temporally reproduced on the same device from the same user’s voice. Public and private keys are generated randomly from the user's voice and stored in the voice file(.wav).This Method uses voice recognition , include the operation of register( recording feature ) or voice prints and storing of one or more voice passwords into the database. It uses ECDSA to perform the authentication process that matching the voice sample with the database. The recognition, entity makes the database to decide that the sample is matched to perform an operation or not. Our proposed approach generates cryptographic keys from voice input itself and this algorithm developed an adhoc basis. It can effectively defend attacks specially brute force attack in system networks
Recruitment of the Fouling Bivalve, Mytilopsis sallei (Recluz), on Metallic and Nonmetallic Surfaces at Visakhapatnam Harbor, India
In 1967, the dreissinid bivalve, Mytilopsis saUei (Recluz), was first noticed in Indian waters at the Southern Lighter Channel of Visakhapatnam
harbor, Andhra Pradesh, India. It is believed that his species was introduced into the Indo-Pacific region from Central America via the Panama
Canal and Fiji through ship foulin
Experiencing space–time: the stretched lifeworlds of migrant workers in India
In the relatively rare instances when the spatialities of temporary migrant work, workers’ journeys, and labour-market negotiations have been the subject of scholarly attention, there has been little work that integrates time into the analysis. Building on a case study of low-paid and insecure migrant manual workers in the context of rapid economic growth in India, we examine both material and subjective dimensions of these workers’ spatiotemporal experiences. What does it mean to live life stretched out, multiplyattached to places across national space? What kinds of place attachments emerge for people temporarily sojourning in, rather than moving to, new places to reside and work? Our analysis of the spatiotemporalities of migrant workers’ experiences in India suggests that, over time, this group of workers use their own agency to seek to avoid the experience of humiliation and indignity in employment relations. Like David Harvey, we argue that money needs to be integrated into such analysis, along with space and time. The paper sheds light on processes of exclusion, inequality and diff erentiation, unequal power geometries, and social topographies that contrast with neoliberalist narratives of ‘Indian shining
Pilot scale studies on the beneficiation of complex sulphides by flotation column
Experiments using pilot size flotation Column as cleaner cell were conducted to evolve a suitable flow sheet for the production of bulk sulphide concentrates of Cu-Pb-Zn. The flotalion circuit consisting of roughing, scavenging, and two stage cleaning by conventional flotation machines
was compared with the circuit where two stage cleaning operation was replaced with single stage cleaning by flotation column. It is clearly demonstrated that a single stage cleaning by flotation column is more efficient and sufficient to obtain bulk concentrate suitable for further
processing. Of the two types of sparger systems used viz, TURBO and MICROCEL, the former was found to be better to achieve high quality concentrate
An Integrative Review of Web 3.0 in Academic Libraries
Purpose – The aim of this paper is to present an integrated literature review exploring the nature of responsive, semantic and interactive Web 3.0 technologies applicable for academic libraries.
Design/methodology/approach – We conducted an integrated review of the literature combining a strategy of automated and keywords search. The main source for identifying the studies are Emerald Library Studies and Information & Knowledge Management eJournals, Web of Knowledge, and Library, Information Science & Technology Abstracts (EBSCO) databases. To this end, a sample of (n= 140) studies were analyzed to characterize the Web 3.0 trends and its applications based on theme, years and document types.
Findings – A review of literature reveals that Web 3. needs evaluation as to what extent they are integrated, deployed and mainstreamed into library services and in information management practices. It is important to develop a conceptual framework that explores the linkages of Web 3.0 technologies and their applications in academic libraries.
Originality/value –This review shows how Web 3.0 technologies enhance library services in its holistic conceptualization and how academic libraries are moving into a more robust, inclusive and adaptable phase in their service values and innovation
A comparative study of the learning styles among 1st, 2nd and final year MBBS students
Background: Learning style is the way students begin to focus, internalize and remember new and difficult information. Identifying the learning styles of medical students will enable the faculty to use appropriate T/L method to increase the grasping ability of their subject/ learning. Purpose of the study was to assess and compare the learning styles of 1st, 2nd and final MBBS students by using VARK questionnaire.Methods: This was an observational, cross-sectional study based on the questionnaire, conducted by the department of Pharmacology at Basaveshwara Medical College and Hospital, Chitradurga. The VARK learning styles assessment questionnaire was administered to 1st (96 students), 2nd (60 students) and Final year (49 students). The students were categorized as auditory, kinaesthetic, visual learner or read/write depending on the predominant option they chose. Independent sample 't' test was used to compare the mean scores between the two groups using the software SPSS v22.Results: 40% of students had unimodal and 60% had multimodal learning style. Final year MBBS students had higher percentage of multimodal learning style (73%). The most preferred style of learning among all the medical students was kinesthetic (6.6), followed by aural (5.5), visual (4.0) and read/write (3.5). There was significant difference between the learning styles of 1st and Final year MBBS students in Visual (p=0.01) and Read /Write (p= 0.008).Conclusions: Knowing that students have different learning styles and kinesthetic being the most preferred mode of learning will help medical faculty to develop teaching/learning strategies for better outcomes
