This paper reports classification of vehicular shape-based objects using Fourier descriptor (FD) technique. Retrieval and classification of different types of shapes was done for closest match, comparing set of feature vectors of query object to each object of every class. Centroid distance based shape signatures were used for derivation of feature vectors. Euclidean distance was calculated as a similarity measure parameter for shape classification. Classification of noisy objects was carried out using FD technique. FD performs better than wavelet descriptor (WD) technique.

Simultaneous job scheduling and tool replacement based on tool reliability by proposed Tabu-SA algorithm



Farhad Kolahan* & Ahmad Sharifinya

Department of Mechanical Engineering, Ferdowsi University of Mashhad, PO Box 91775-111, Mashhad, Iran

This paper addresses integrated job scheduling and tool replacement problems in a single machine environment with objectives to determine optimal job sequence, tool selection for operation, tool replacement schedule, and number of spares for each tool type, in such a way that total expected production cost is minimized. Since problem is NP-hard, a hybrid algorithm [Tabu-simulated annealing (SA)] is proposed to simultaneously provide job sequencing, tool replacement intervals and number of spare tools required. Tabu-SA is examined and results are compared by solving a real-sized example problem.

This paper incorporates a multi-delivery policy and quality assurance into an imperfect economic production quantity (EPQ) model with scrap and rework. Expected integrated cost function per unit time is derived. A closed-form optimal batch size solution to the problem is obtained. Two special cases are examined and a numerical example given to demonstrate model’s practical usage.

This paper presents design of autonomous mobile robot MBR-01 for speed and position control on variable trajectory depending on trajectory curvature. MBR-01 can communicate reciprocally with host computer using RF data transceiver. Reference speed is applied to fuzzy controller unit and output is sent to vehicle by wireless transmitter unit. Received control signal by vehicle is transferred to DC motor drive system with Pulse Width Modulation techniques. Position control is realized by microprocessor-based units mounted on vehicle. Equipped 7 optical sensors detect trajectory deviation and wheel angle of vehicle for track detection and wheel angle detector unit.

This study analyzes effects of vibrations on comfort and road holding capability of vehicles as observed in variations of suspension springs, road roughness etc. Also, design of non-linear experimental car suspension system for ride qualities using neural networks is presented. Proposed active suspension system has been found more effective in vibration isolation of car body than linear active suspension system. Proposed neural network predictor could be used in vehicle’s suspension vibration analysis.

Voltammetric behaviour of nitrazepam in solubilized systems






Rajeev Jain*, Ritesh Mishra & Ashish Dwivedi

School of Studies in Chemistry, Jiwaji University, Gwalior-474011, India

Voltammetric behaviour of benzodiazepine tranquilizer drug, nitrazepam, has been studied in acetonitrile using cyclic voltammetry and differential pulse polarography. Nitrazepam exhibits two well-defined cathodic peaks in acetate buffer (pH 3-6). Lower limit of detection (LOD) and lower limit of quantification (LOQ) are found to be 0.47x10-7 and 1.5x10-7 mol l-1 respectively. Analysis of nitrazepam in pharmaceutical formulation exhibited mean recoveries of 99.3 % and 99.6 % for both reduction peaks. Addition of anionic surfactant (sodium lauryl sulphate) to nitrazepam containing electrolyte also exhibit two well-defined cathodic peaks. Reduction process was irreversible over entire pH range.

Flame retardant study of cotton coated with intumescents: Kinetics and effect of metal ions













J B Dahiya* & Krishan Kumar


Department of Chemistry, Guru Jambheshwar University of Science and Technology, Hisar 125 001, India

Oxidative thermal degradation and flame retardant behaviour of cotton fabric coated with intumescent formulations containing nanoclay as well as metals (Cr, Cu and Zn) were studied by thermogravimetry (TG), differential thermal analysis (DTA) and limiting oxygen index (LOI). Activation energy of coated fabric with intumescent (165.8 kJ mol–1) was found lower than that of uncoated cotton fabric (226.5 kJ mol–1), which further decreased on inclusion of metals in intumescent formulations (111-127 kJ mol–1). Char yield for coated fabric with intumescent increased from zero to 11.9% at 600°C. LOI value for pure cotton fabric (18%) increased for intumescent-coated fabric (21.8%).

Roselle (Hibiscus sabdariffa) fruits, a potential source of natural dye, contain anthocyans, organic acids and carbohydrate. This study presents dye adsorption from aqueous solution onto activated carbon with emphasis on equilibrium and kinetics studies. Langmuir model provides better fit of data. Adsorption of Roselle dye on activated carbon has been found as a prospective separation method of natural red dye.
