Trust in Vehicle-to-Vehicle Communication
In traditional Pedestrian Automatic Emergency Braking (PAEB) system, vehicles equipped with onboard sensors such as radar, camera, and infrared detect pedestrians, alert the driver and/ or automatically take actions to prevent vehicle-pedestrian collision. In some situations, a vehicle may not be able to detect a pedestrian due to blind spots. Such a vehicle could benefit from the sensor data from neighboring vehicles in making such safety critical decisions. We propose a trust model for ensuring shared data are valid and trustworthy for use in making safety critical decisions. Simulation results of the proposed trust model show promise
Non-homeomorphic Nilmanifolds with Identical Unitary Spectrum
AbstractWe show in every three-step nilpotent Lie groupGwith all coadjoint orbits flat the existence of a pair of discrete cocompact subgroupsΓ1andΓ2such thatΓ1\GandΓ2\Ghave the same unitary spectrum butΓ1is not isomorphic toΓ2. This result generalizes an example of Gornet. We mention without giving a proof a result that would enunciate that for a large category of subgroups of the four dimensional three-step chain group with non-flat coadjoint orbits, this phenomenon of non-isomorphic representation equivalence cannot occur. We also prove some short structural results for three-step nilpotent Lie groups with one-dimensional center
Impact of organic techniques of seed crop management on seed yield and quality in rice
A study was conducted at the Department of Seed Science and Technology, Tamilnadu Agricultural University, Coimbatore in June - July season of two different years to find out suitable organics for enhanced productivity of rice cv ADT 43 for organic seed production. The results revealed among the organic soil application of neem cake (1786 kg ha-1) along with 3 per cent panchakavya foliar spray maximized the yield along with yield attributing characters (plant height, total number of tillers hill-1, productive tillers hill-1, chlorophyll content, panicle length) and resultant organic seed quality characters. However, the yield was higher with basal nutrients applied as inorganic (3537 kg ha-1 in initial and 4352 kg ha-1 in confirmation), which was on par with neem cake + panchakavya (3500 kg ha-1 in initial and 4315 kg ha-1 in confirmation), GLM + azolla (3380 kg ha-1 in initial) and GLM + azolla + panchakavya (4213 kg ha-1 in confirmation) treatments and sprayed with panchakavya at vegetative, flowering and maturity. These findings are highly useful for paddy organic seed production programme
Cross Lingual Information Retrieval Using Data Mining Methods
One of the challenges in cross lingual information retrieval is the retrieval of relevant information for a query expressed in a native language. While retrieval of relevant documents is slightly easier, analyzing the relevance of the retrieved documents and the presentation of the results to the users are non-trivial tasks. A method for information retrieval for a query expressed in a native language is presented in this paper. It uses insights from data mining and intelligent search for formulating the query and parsing the results. It also uses heuristic methods for the categorization of documents in terms of relevance. Our approach compliments the search engine’s inbuilt methods for identifying and displaying the results of queries. A prototype has been developed for analyzing Tamil-English corpora. The initial results have shown that this approach is suitable for on the fly retrieval of documents
Tobacco and health: What can the medical profession do?
Tobacco consumption, that leads to three million
deaths every year of which about one million occur in
developing countries is a social evil(1). Tobacco smoke
is a complex mixture of as many as 4700 individual
constituents including carcinogens, irritants, ciliotoxic
substances and poisonous gases. There is no dearth of
information about the health hazards to smokers. it has
been implicated as a major risk factor in a variety of
chronic diseases including cardiac, cerebrovascular,
malignant, respiratory and other diseases (2), Most of
the smoking related lung diseases (e.g. chronic obstructive
lung disease and lung carcinoma) are dose dependent.
it is often the cumulative dose of smoking which
determines the risk. Parameters like pack-year (PY)
have been used to express exposure to tobacco smoke.
One PY implies one packet of cigarettes (or 20 gms.
tobacco) smoked each day over a course of one year (3).
In India the number of cigarettes and bidis per packet is
quite variable. A standard packet of cigarette and bidis
per packet is quite variable
Biotransformation of tuna waste by co-fermentation into an aquafeed ingredient
Dried skipjack tuna (Katsuwonus pelamis) waste (red
meat, gills, viscera, ¢ns, etc.) were mixed with 25%
wheat flour and inoculated with a starter culture
of Lactobacillus plantarum National Collection of
Industrial Microorganisms (NCIM) 2912 (108^
109 cellsmL_1) and Bacillus licheniformis MTCC
6824 (107^108 cellsmL_1). Changes in the nutritional
quality (crude protein, crude fat, crude ash,
crude ¢bre and nitrogen-free extract and aminoacids)
were monitored during a fermentation period
of14 days
Design and Implementation of Open Journal System (OJS) for Rajagiri Journals: A Review
Open Access (OA) is an alternative business model for the publication of scholarly journals. It makes articles freely available to readers on the Internet and covers the costs associated with publication through means other than subscriptions. Online Journal System (OJS) is an end to end publishing management platform offered by Public Knowledge Project (PKU) which will help Journal publishers and content developers to manage its journal website along with managing pre-publishing editorial activities including manuscript management, peer review process & publishing process. The OJS platform will cover all aspects of online journal publishing, from establishing a journal website to operational tasks such as the author\u27s submission process, peer review, editing, publication, archiving, and indexing of the journal. It also helps to manage the people facets of organizing a journal, including keeping track of the articles, the work done by the editors, reviewers, and authors, notifying readers, and assisting with the communication. In this paper, we try to discuss the practical challenges and way to overcome it which we implemented Rajagiri Journals through OJS platfor
Water-mediated variability in the structure of relaxed-state haemoglobin
The crystal structure of high-salt horse methaemoglobin has been determined at environmental relative humidities (r.h.) of 88, 79, 75 and 66%. The molecule is in the R state in the native and the r.h. 88% crystals. At r.h. 79%, the water content of the crystal is reduced and the molecule appears to move towards the R2 state. The crystals undergo a water-mediated transformation involving a doubling of one of the unit-cell parameters and an increase in water content when the environmental humidity is further reduced to r.h. 75%. The water content is now similar to that in the native crystals and the molecules are in the R state. The crystal structure at r.h. 66% is similar, but not identical, to that at r.h. 75%, but the solvent content is substantially reduced and the molecules have a quaternary structure that is in between those corresponding to the R and R2 states. Thus, variation in hydration leads to variation in the quaternary structure. Furthermore, partial dehydration appears to shift the structure from the R state to the R2 state. This observation is in agreement with the earlier conclusion that the changes in protein structure that accompany partial dehydration are similar to those that occur during protein action

ANALYSIS OF MIXTURES OF REFRIGERANT FOR VAPOUR COMPRESSION REFRIGERATION CYCLE USING MATLAB-SIMLINK
The goal of this work is to predict the performance of the compression cycle of different refrigerants. Incompression refrigeration system, the refrigerant such as R22, R290 & R407C are considered as a refrigerant bymixing of these at a different mass fraction as 40%+30%+30%, 30%+40%+30%, 30%+30%+40%, 40%+20%+40%,40%+40%+20% and 20%+40%+40% respectively. Experimental conditions for the condensing temperature wereselected as 40,45&50 °C and evaporating temperature were selected 1,5 & 10°C. Various performance measures likeCOP, Volumetric Efficiency, Mass Flow Rate, Isentropic Compressor Work, Refrigeration Capacity, Compressorpower, Compressor Outlet Temperature, Pressure Ratio & Overall Performance Index uses a several refrigerantmixture with the help of MATLAB-SIMLINK tool. Among these pure refrigerants and mixture of refrigerantsgroup, R290 and 40%+40%+20% has a better COP
