Abstract

Assessment of the students' performance forms an integral part of any process of teaching and learning. Reliable and valid assessment is very necessary to provide effective feedback to the students, to increase their level of motivation and self-esteem, to let them know how to improve and to provide remedial teaching, etc. However, all the said purposes will be served only when assessment is regular, active, clear, as well as timely. It involves professional judgment based on evidence and measurement. Since in our country most of the assessment process at school stage is related with the psychological pressure, stress and anxiety felt not only by the students but also their parents, teachers and policy makers and society at large. Hence, specific measures must be taken to ensure reliable, valid, objective and timely assessment of the students at school stage so that all can encompass the bitter and extreme ill consequences and be prepared for entire learning life besides ensuring minimum level of (quality) learning. Though many education commissions, committees and educational policies (Secondary Education Commission, 1952-53; Education Commission, 1964-66; NPE, 1986 and modified NPE, 1992) advocated the reforms in assessment process at school stage, the issue acquired the added significance after the release of NCF, 2005 by NCERT. Various issues related to assessment at school stage have been highlighted along with solutions in the position paper by NCERT (National Focus Group on Examination Reforms). With advancements in information technologies, it is now thought that it would provide solutions to many problems related with the assessment of the students at school stage. Information Technology (IT) based assessment ensures the reliable, valid, objective and timely assessment and can be applied to a wide range in School Assessment Process including various curricular and co-curricular activities. Also, IT based assessment is essential due to the realization of continuous and comprehensive evaluation in real sense as it involves varied aspects of assessment of the students that may not be judged as effectively and objectively as by the use of IT. Secondly assessment needs to be carried out through out the year which involves conduct of assessment including many pre and post assessment activities. But there are a lot of challenges related to it and suitable strategies have to be chalked out to meet those challenges. The present paper explores the challenges and strategies in information technology based assessment at school stage.

Abstract

The intake of low concentration of hydrophilic polysaccharides such as gum is beneficial as it increases the bulk of intestinal content and also prevent excessive absorption of fat. The importance of hydrocolloids in food applications is due to their unique, functional properties like water binding capacity, reduction In evaporation rate, alteration in freezing rate, modification in ice crystal formation, regulation of rheological properties, participation in chemical transformations, suspension of insoluble particles and stabilization of foams and emulsions.

Abstract

An investigative work was conducted to examine the tensile, flexural and impact strength of carbon fiber reinforced vinyl ester composites filled with different proportions (0, 0.5, 1, 1.5 and 2) of graphitic carbon nitride (g-C3N4) and silicon nitride (Si3N4) filler. Composites were fabricated by hand layup method. Results showed an increase in tensile strength of g-C3N4 and Si3N4 particles content by 1% and beyond which the strength decreased. With the addition of 1wt% of g-C3N4 and Si3N4 in carbon fiber reinforced vinyl ester composites, the flexural strength increased to 16% and the tensile strength increased by 10%. The eroded surface of specimen was observed under scanning electron microscope and the results are reported. Incorporation of nano fillers in hybrid polymer composite will enhance the mechanical properties. Hence hybrid C-V extensively used in marine applications.

Abstract

Synthetic fiber reinforced composites have already been proved to be stronger and more durable. The composites are being globally used in all the possible fields like automobiles, aircraft and marine industry. The present work is an investigation on the wear behaviour of the hybrid polymer composites. In this experimental work, the carbon fibres are reinforced with vinyl ester, g-C3N4 and Si3N4 were used to obtain hybrid composite by hand layup technique. The experiments were designed according to Taguchi (L27) orthogonal array. Experiments are carried out using slurry abrasive wear testing machine to inspect the wear rate. Further, a fuzzy logic model is adopted for the estimation of sliding wear in hybrid composites by the experimental data. Results showed that estimated fuzzy logic outputs are compared to experimental results, which is very much satisfied with a mean error estimation of 0.27%, so that the fuzzy logic model can be efficiently used to compute the wear performance.
