Supplier selection by F-compromise method: a case study of cement industry of NE India

Abstract: In this paper, we initially conducted a brief review of supplier selection methods to find most cited multi-criteria decision making method, present trend of supplier selection and most cited criteria for supplier selection. Our study reveals that irrespective of several limitations of analytic hierarchy process (AHP), AHP and its integrated model is most preferred supplier selection method. Present research trend of supplier selection gives more emphasises on multiple sourcing instead of single sourcing. Based on our initial study, a suitable integrated model is proposed. In this integrated model, fuzzy analytic hierarchy process (FAHP) and VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje; in Serbian) is used to select suppliers from a predefined supplier base. Multi-objective genetic algorithm (MOGA) is used further to allocate order among suppliers. Finally, a case study is discussed to use proposed method.

A novel approach of secret message passing through text steganography

Abstract: Today's internetworking globe is full of busy roads for transferring data. Challenges on sending or receiving various kinds of hidden data, messages or information especially using this public networks. Hackers took place to leak this surreptitious data. That's the reason behind the need of a cover media where the furtive message has been hiding our information securely. Steganography, one of the popular technique for putting out of sight for a message surrounded by other media (cover) devoid of any hesitation or distrust to an additional one, which means the message will just identified by the authenticate and predetermined recipient. Using this concept a unique number system is introduced through a text message as a cover media. This paper will help the scholars as well as researchers to move towards an innovative area of research for secret message transfer.

Effect of fluid concentration using a multi-nozzle on grinding performance

Abstract: Grinding fluid, apart from controlling temperature produced at the wheel-work contact zone by way of cooling also helps in lubrication which is achieved by reduction of friction at the wheel-workpiece interface. In the present experimental investigation, grinding fluid is delivered into the grinding zone by a multi-nozzle system in order to determine grindability of low alloy steel at different fluid concentrations. A comparative study has been made among dry and wet grinding using three different coolant concentrations, considering various response parameters, to assess grinding performance at a particular in feed. It is found that high concentration of oil in the fluid produced good results in terms of force requirement and surface roughness.

Multitechnique Rain Classification From Ground-Based Measurements Over a Tropical Location

Abstract: This article aims to classify precipitation into two categories, namely stratiform and convective. Multiple techniques, such as utilizing the micro rain radar (MRR), electric field monitor (EFM), radiometer, and disdrometer measurements, have been deployed for this purpose, at a tropical location Kolkata, India. A new rain classification technique, using logistic regression modeling of the sixth to third moment ratio ${(M6/M3)}$ , has been proposed. Classification of rain types based on the new technique shows high consistency with that based on radar reflectivity ( ${Z}$ ) values obtained from disdrometer measurements. This article also distinguishes mixed rain from stratiform and convective rain. The observations on the bright band structure by MRR and on differential brightness temperature at 31.4 and 22.23 GHz by a radiometer are utilized to classify mixed rain types. Although the EFM measurements do not classify rain types directly, they give a distinct signature of the impending stratiform/convective rain events. A comparative analysis between the percentage of stratiform and convective rain durations shows significant dominance of stratiform rain over convective rain. At the present location, the convective phenomenon shows higher occurrences during the pre-monsoon period compared to the monsoon period.
