The purpose of this paper is to introduce the design of a training tool intended to improve deminers' technique during close‐in detection tasks.

Following an introduction that highlights the impact of mines and improvised explosive devices (IEDs), and the importance of training for enhancing the safety and the efficiency of the deminers, this paper considers the utilization of a sensory tracking system to study the skill of the hand‐held detector expert operators. With the compiled information, some critical performance variables can be extracted, assessed, and quantified, so that they can be used afterwards as reference values for the training task. In a second stage, the sensory tracking system is used for analysing the trainee skills. The experimentation phase aims to test the effectiveness of the elements that compose the sensory system to track the hand‐held detector during the training sessions.

The proposed training tool will be able to evaluate the deminers' efficiency during the scanning tasks and will provide important information for improving their competences.

This paper highlights the need of introducing emerging technologies for enhancing the current training techniques for deminers and proposes a sensory tracking system that can be successfully utilised for evaluating trainees' performance with hand‐held detectors.

The metal detector used as a wall scanner has become a kind of popular household instrument. It is important to possess the characteristics, including low-cost, reliability, easy repeatability and simple procedure in this device. The purpose of this paper is to found a model of differential probe applied to metal detector.

The new model consists of an emitting coil and a differential receiving coil. The emitting coil uses winding inductance to produce a magnetic field and the receiving coil senses the change of magnetic flux. All turns of the receiving coil are designed in the same plane, so it can be fabricated with signal printed circuit board. The balance of differential probe is promised by the constraint relation of the parameters, including the radius and the turns of the receiving coil and the emitting coil. A novel fine adjustment has been proposed to offset the design error that can make the model more ideal.

The differential probe can be produced easily and need not to be calibrated. In the design, the amplifier and the filter circuit is used for the output signal processing and the harmonic analysis based on Fourier transform is used to analyze the voltage signal in order to detect and distinguish the metallic object. The differential probe in the prototype, which area is π×352 (mm2), can detect the cylindrical metallic object including iron, and aluminum which thickness is 2 mm and radius is 30 mm in the distance of 120 mm.

The model of differential probe proposed in the paper is feasible and effective to apply in the hand-held metal detector.

Physical security has remained an important reason for, and the consequence of, societal living. In recent times, the threat potential and the risks of loss and damage due to criminal activities have increased substantially. In Indian Railways, it is being increasingly felt that efficient security management is inevitable for the development and sustainability of desired state of affairs. The purpose of this paper is to address the broad goal of achieving optimal strategies for minimizing security threats to Indian Railway Security System (IRSS).

The authors use two forecasting techniques, namely, Delphi technique and Harva method, whose joint approach allows the authors to use both quantifiable (Delphi technique) and linguistic (Harva method) data. The choice of the two approaches provides a multi-method approach to the research problem.

Predicted trend toward the expected scenario in 2020 has more or less matched with the actual developments for improvement in security scenario of Indian Railways. The positive indications are that there is an improving trend, which is expected to lead to a much better state of affairs with certain inputs.

The joint approach of Delphi technique and Harva method is a multi-method example of original research work in the railway security, which can also be implemented in other security settings, such as aviation or marine security. A replication of the exercise closer to the target date will throw light on the exact state of affairs in the area of railway security in India.

An outcome in consonance with the present exercise has been the implementation of the policy developed on the basis of the forecasts. Policy efforts initiated in the recent past have been consistent with the features discussed in the study. From the above indicators, it can be inferred that some of the policy initiatives taken are in line with the trend status as predicted by the Delphi exercise.

Security has been considered as an important reason, as well as a consequence, of living in a society. It has been perceived as the condition of being protected against danger or loss, and also refers to the freedom from exposure to danger (protection), implying a feeling of assurance against danger. Research work in this area, thus, has strong social welfare implications. This is particularly so as the area of security gained importance, not only in India, but also across the world.

The present study is the first of its kind in the area of railway security using systems approach. The approach used is quite generic and can also be implemented in other security settings, such as aviation or marine security.
