The study is for design and development of an electronic hydrometer for measurement of non magnetic liquid density in a container. The electronic hydrometer systems are of extreme use in industries and production plants of chemically and radioactively sensitive materials. In this paper electronically developed scheme has been proposed for measuring real time liquid density, magnetically actuated reed switch has been used for designing the system. Readings of the hydrometer are available digitally & displayed on a remotely located indicator for supervision. Novelty of the system lies in the simplicity of its operation, remote supervision and reliability in extreme environment.

This paper presents discrete sliding mode control (DSMC) for nonlinear model of an inverted pendulum system. The reaching law method is used during the DSMC design. The uncertainties are structured in that system by considering the existence of an error during the pendulum angle measurement. The designed controller is compared with Linear Quadratic Regulator (LQR) controller to observe the capability for controlling the highly nonlinear system of the inverted pendulum. The performance and reliability of the proposed algorithm are determined by performing extensive simulation works using MATLAB/Simulink platform. The result shows that DSMC can produce better response as compared to LQR control strategy.

This paper describes the design of Proximity Warning System for Train Driver, principally is to give warning using radio wave transmission when the pathways ahead is being occupied by other train, the radio transmission will then activate buzzer in the locomotives as audible warning/alarms, within few seconds unless being reset the system will activate train braking system so expectedly collision could be avoided‥

The implementation of autonomous behaviour in unmanned systems is one of most challenging tasks today. Although the underlying algorithms for decision-making are well known, do no implementations exist for certifiable time-triggered embedded realtime operating systems as used by all modern aerospace and automotive products today. In this publication we present the new approach of realtime decision-making. It allows the a-priori calculation of time and space bounds as a prerequisite for the integration of decision-making in time-triggered embedded software systems.

This paper investigates the application of a robust hybrid control design for a small scale helicopter flying with multiple linearised mathematical models. A hybrid control architecture is proposed and will be developed to cope with the complexity of the non-linear system. A class of this control system is known as hybrid control systems which deal with dynamic changes and jump transition behaviour between the changes. The small scale helicopter is known to inherently have these features. In this paper, the behaviours of the small scale helicopter are represented into five linearized models at trim conditions. When a wider region of flight envelope is considered, this approach leads to a switching problem representing changes from one mode to another mode in a predifined order for a safe and successful flight. In this paper we specifically investigate the control of transition dynamics between many modes as a hybrid system. One approach of control for hybrid switch system is characterized by Linear Matrix Inequalities (LMIs) for performance analysis and control synthesis. State jumps of the controller responding to switched of plant dynamics are exploited to improve control performance.

In this paper we investigate safety verification of linear system. The structure of linear system will be exploited and converted to certain eigenstructure as an emptiness problem for a semi algebraic set. Sum of square (SOS) is emploited to check emptiness of of the set defines by polynomial inequalities which can be computed by semidifinite programming. A special consideration is to investigate safety problem of linear system with complex eigenvalues.

An automated wood recognition system is designed to classify tropical wood species. The wood features are extracted based on two feature extractors: Basic Grey Level Aura Matrix (BGLAM) technique and statistical properties of pores distribution (SPPD) technique. Due to the nonlinearity of the tropical wood species separation boundaries, a pre classification stage is proposed which consists of Kmeans clustering and kernel discriminant analysis (KDA). Finally, Linear Discriminant Analysis (LDA) classifier and K-Nearest Neighbour (KNN) are implemented for comparison purposes. The study involves comparison of the system with and without pre classification using KNN classifier and LDA classifier. The results show that the inclusion of the pre classification stage has improved the accuracy of both the LDA and KNN classifiers by more than 12%.

This paper describes a new class of point-of-care (POC) diagnostic devices for quantifying multiple assays by fabricating microfluidic devices on cotton cloth. This kind of microfluidic systems is appropriate for colorimetric assays that are low-cost, portable and simple to fabricate and to operate. Hydrophilic channels with hydrophobic barriers can be created using wax-resist patterning technique on cotton cloth fabric inspired from traditional batik technique. Using capillary force, the porosity of woven fabric and threads can wick micro volumes of aqueous samples from sample inlet into reaction zones across the hydrophilic channels for the mixing of their contents. These devices can be designed to perform single and multiple colorimetric assays of body fluids. The result can be observed by unaided human eye or by using digital camera and image analysis software.
