A groupoid is medial if it satis_es the identity wx • yz = wy • xz. A groupoid is trimedial if every subgroupoid generated by 3 elements is medial. Medial groupoids and quasigroups have also been called abelian, entropic, and other names, while trimedial quasigroups have also been called triabelian, terentropic, etc. (See [5], especially p. 120, for further background). The notion of variety of algebras having the property (k, n) was given in [6] and equationally defined classes of cancellative groupoids having the property (2, 4) and (2, 5) were considered there. This notion was qeneralized in [7], where it was shown that the condition of the cancellativity is superfluous, that is, any variety of groupoids with the property (2, n) is a variety of quasigroups. Let k and n be two positive integers and k n. An algebra A is said to have the property (k, n) if every subalgebra of A generated by k distinct elements has exactly n elements. We also say that A is a (k, n)-algebra. A class K of algebras is said to be a (k, n)-class if every algebra in K is a (k, n)-algebra. A variety is called a (k, n)-variety if it is a (k, n)-class of algebras. Trivially, the variety of Steiner quasigroups (xx = x, xy = yx, x•xy = y) is a (2, 3)-variety. It is the unique variety of groupoids with the stated property, and the same holds for the (2, 4)-variety (x•xy = yx, xy•yx = x) given by Padmanabhan in [6]. He has also constructed two (2, 5)-varieties. One of them is commutative (xy = yx, x(y•xy) = y, x(x•xy) = y•xy), while the other one (x•xy = y, xy•y = yx) consists of anticommutative quasigroups. It is an verify the existence of (2, n)-varieties for n?10

In Networks-On-Chips, (NOC) global interconnection links and routers are the main sources of the power Consumption. In Application Specific NOC (ASNOC) power can be minimized by mapping the Processing Element (PE) on the custom topology rather than mapping on the standard topologies. In ASNOC, the design of the topology plays an important role in minimizing the power consumption. In this paper, we propose a custom topology generation algorithm using network partitioning, to reduce the power of the global interconnection links that connects the router to router. The proposed method is validated through a case study for benchmark video applications MPEG 4 decoder and PIP. The experimental case study shows 26.8% and 37.5% of power saving for the applications MPEG 4 decoder and PIP respectively compared to the existing algorithm. We also achieve 11.76% and 9 % of reduction in average number of hops for MPEG 4 decoder and PIP respectively.

The National Assessment and Accreditation Council (NAAC), an autonomous institution of U.G.C., New Delhi, having the responsibility of assessment and accreditation of colleges and universities in India has redesigned its methodology of assessment and accreditation on the basis of its own field experience, shared knowledge with international quality assurance agencies and quality imperatives in the changing global scenario in higher education. The new methodology has come into effect from 1st April 2007, with a view to enhance its rigor, reliability and validity. The sample has been taken from 44 institutions of higher education in Haryana. 7 teachers from each institution who were the members of the IQACs were included in the sample. These 44 institutions include 19 urban aided institutions (13 co-ed. And 6 women colleges), 8 urban government institutions (5 co-ed. and 3 women colleges), 11 rural aided institutions (3 co-ed. and 8 women colleges) and 6 rural government institutions (3 co-ed. and 3 women colleges).

Automated Fruit Grading System is challenging task in ICT in agriculture. This paper presents a new fruit grading system using artificial neural networks (ANN). The classification systems are based on features extracted from fruits obtained from image processing feature extraction methods. Two different types of classifiers as multi-layer perceptions (MLP) with back propagation and radial basis function (RBF) networks. The objective of this study are to define a optimistic set of external quality features of fruits from the primitive features like color, texture and shape of fruits and to examine the effectiveness of the model. In this experiment, the performance of the system achieved 87.5% and 91.1% respectively for MLP with back propagation and RBF.

The biological parameters and zooplankton diversity of a Tampara Lake shows healthy aquatic ecosystem. The plankton constitutes the basic food source of any aquatic ecosystem. Zooplankton diversity is one of the most important ecological parameters in water quality assessment. Zooplankton are strongly affected by environmental condition and quickly respond to any change in water quality. So these are good indicator of ecosystem and occupy an intermediate position between phytoplankton and fish. Hence qualitative and quantitative studies of zooplankton are of great importance. During the study zooplankton diversity in relation to biological parameters was discussed to the investigation find that 22 species of zooplankton belonging to four major groups, i.e. 10 species of Rotifera six species of cladocera and three species of copepoda and three species of protozoan.

Oral habits are very common and one of the most deleterious habits which pose a problem to pediatric dentists. Oral appliances, if inserted for several months, usually eliminate the habit, however, emotional problems, difficulty with speech and hearing, and self inflicted wounds can occur with such appliances. We present a case of 8 year old girl with thumb sucking habit, successfully managed by a non punitive bluegrass appliance.

In this paper the existence of odd and even ratio edge antimagic labeling for double triangular snakes (2?k-snake), 2m?1-snake, 2m?k-snake and kC4-snake are proved.

This paper proposes a the common sharing distributed arithmetic method with less number of flip flops to reduce the power consumption by the circuit. To achieve the lesser number of Flip flops usage the registers used in the circuit to create latency will be replaced by buffers. By using the buffers in the circuit itself can create some latency efficiently than using the more number of flip flops in the circuit.

The main chemical used for the gold mining is Mercury. It is widely considered to be among the highest priority environmental pollutants of great concern to the world. Concerns about mercury are based on its effect both on ecosystems and human health. Mercury levels in various foodstuffs were determined by instrumental neutron activation analysis (INAA). High level of Hg was found in all the foodstuffs collected from mining areas. Generally, Hg concentration in foodstuffs ranged from Capsicum sp <0.01 to 69 µg/kg > Xanthosoma sagittifolium <0.01 to 67µg/kg, Nbelmoschus esculentus <0.01 to 67 µg/kg > Colocasia esculentus <0.01 to 66 µg/kg > Manihot esculentus <0.01 to 65 µg/kg , Musa paradisiacal <0.01 to 65 µg/kg , leaves of Xanthosoma sagittifolium, <0.01 to 65 µg/kg > Solanum melongena <0.01 to 63 µg/kg, > Lycopersicum esculentus <0.01 to 54 µg/kg. Most of the values far exceed the WHO recommended values of Hg in foodstuffs, 20ngHg per gram fresh weight. This is not surprising because of the large amount of mercury the illegal miners add in order to be sure that they have all amalgamated available gold. Hg levels should be carefully monitored in the Wassa west district in Ghana.

In this research modeling of moisture content of three different varieties of bean (Talash, Sadri and MahaliKhomein) was studied during soaking by applying Khazaei mathematical model and artificial neural networks (ANNs). The procedures were carried out in three experimental temperatures (5, 25 and 45?C) in distilled water. Water abortion characteristics of samples were considered by measuring the increase in the mass of seeds with respect to time. Amulti layer perceptron (MPL) and radial basis function (RBF) approach were used with three layers of neurons, in designing ANNs. The soaking temperature and time were used as input parameters and the moisture content was used as output parameter of ANNs. To evaluate the prediction of mathematical and ANNs model, coefficient of determination (R2),root mean square error (RMSE) and distribution of residual errors plot were used. The results indicated that the MLP approach using back propagation training structure, Broyden- Fletcher- Goldfarb- Shanno(BFGS) algorithm and 2-6-1 topology of the network achieves the best results for moisture content estimating in three studied varieties of bean. Besides that, the instant moisture content curves based on temperature and time independent variables using MLP method expressed with increasing the time and temperature of seed immersion, water absorption is increasing.
