Research on explosive vapour detection system for high level security check of terrorist explosives

The terrorist attacks that occurred in the US on 11 September 2001 ushered in an era of increased security and tighter restrictions for those wishing to travel by aeroplane. In 2015, an article by ABC News revealed that an internal investigation of the Transportation Security Administration showed significant security failures at numerous airports across the US. Undercover investigators were able to smuggle mock explosives and banned weapons through checkpoints in 95 per cent of cases. One of the main reasons for mock explosives and banned weapons getting through checkpoints is the increase in the amount of travellers and volume of cargo. Aeroplanes need to be able to take off on time, so inspecting 100 per cent of the goods and people that are travelling is practically impossible. A team of researchers based within the National Institute of Technology, Toyama College in Japan is tackling this problem by investigating a means of developing an explosive vapour detection system. Associate Professor Yotsumi Yoshii and Professor Iwao Mizumoto are leading the project, the aim of which is to facilitate high-level security checks for terrorist explosives and therefore prevent disastrous events in the future

Development of electronic circuits that can operate in high radiation environments such as nuclear power plants

Robots can play a vital role in disaster rescue, relief and recovery. These versatile machines can perform tasks humans cannot and can enter into dangerous environments otherwise inaccessible to human workers. However, they are not invincible and there are still some situations where robots and the electronic components they're made of fail. By studying the limits of electronics in these extreme scenarios though, better components can be developed and deployed on robots; keeping these invaluable workers online in the most dangerous and urgent of situations. The ongoing decommissioning work at the devastated Fukushima Daiichi Nuclear Power Plant is an example of this. The earthquake that destroyed the plant happened nearly 11 years ago, yet the clean-up at Fukushima is still ongoing. Long term efforts are needed in order to resolve the issues such as decontamination of the scattered radioactive materials, contaminated water, and decommissioning of the nuclear reactor itself. Associate Professor Kenichiro Takakura, from the Electronics Materials and Devices Research Group at the National Institute of Technology (KOSEN), Kumamoto College, is carrying out research to develop electronic equipment that can be used in a nuclear reactor to assist with the early completion of decommissioning.

Invention of Indian Moon Soil (Lunar Highland Soil Simulant) for Chandrayaan Missions

Indian Space Research Organization (ISRO) planned the Chandrayaan missions 2 and 3 to explore the South Polar Region of the Moon, which is believed to consist of lunar highland soil. As a part of its moon-landing mission, it is necessary to prepare a “lunar surface terrain testbed” so that the lander and rover could be tested under simulated conditions. This has resulted in a requirement of around 50 tons of lunar soil simulant, which can match with actual lunar highland soil with respect to chemical/mineralogical composition, particle size distribution, and some selected geomechanical properties, including the trafficability parameters, as reported in the literature. Though earlier, some countries (like USA, China, and Canada) have produced limited quantities of lunar highland soil simulants (LHSS), as reported in the literature, there was a compelling need to indigenously manufacture a large amount of lunar soil simulant (LSS) under the policy of “MAKE IN INDIA”. This technical note explains the development of a new lunar highland soil simulant LSS-ISAC-1 (that is jointly invented by ISRO Satellite Centre (ISAC) along with Periyar University, Salem and National Institute of Technology, Trichy—Tamilnadu) and its engineering properties, which was manufactured in a large quantity using the natural terrestrial anorthosite rocks. Furthermore, this note also highlights the futuristic research areas, where this soil simulant can be advantageously used for further research and development works.

Designing efficient communication infrastructure in post-disaster situations with limited availability of network resources

In the aftermath of a large-scale disaster, such as an earthquake, existing telecommunication (e.g., cellular towers) and other public infrastructures (e.g., power lines, roads, etc.) are often severely damaged. This prevents the seamless exchange of situational awareness and rescue/relief based information between the volunteers, shelter points, and the coordination center. A temporary communication infrastructure utilizing smartphones, communication towers, drones, smart badges, etc., commonly referred to as network resources, can be formed, which promises to bridge the communication gap between various stakeholders in the disaster area and enable timely information exchange between them. However, the efficacy of such networks is often challenged by the limited availability of network resources in the disaster area. To address this issue, in this paper, we propose to design, develop, and test a novel strategy that intelligently deploys the limited network resources in the disaster area, and thus, creates an efficient temporary communication infrastructure in such resource-constrained post-disaster situations. We formulate the network resource deployment (ResDep) problem as an integer linear programming optimization problem and show that it is NP-Hard. Next, we propose a near-optimal polynomial-time heuristic solution for solving it. Our extensive simulation study on top of ONE simulator and proof-of-concept pilot deployment study, both based on our university, National Institute of Technology — Durgapur, India, reveal that the proposed heuristic performs nearly as well as that of the optimal solution (computed using Gurobi optimizer), and outperforms its variant and baseline approaches when compared in terms of end-to-end network latency and message delivery.

Security ambiguity and vulnerability in G2C eGovernance system: Empirical evidences from Indian higher education

The Higher Education Institutions (HEIs) in India enhanced dependency on Information Communication Technology (ICT) based on G2C eGovernance applications persistently raised apprehension regarding cyber-attacks and breach of security. Objectives:The present study assesses the status of ambiguity and vulnerability pertaining to security aspects of HEIs G2C eGovernance web portals. Methods:Five prominent central and state HEIs i.e. Malaviya National Institute of Technology - Jaipur (MNIT), National Institute of Technology - Kurukshetra (NITK), Guru Nanak Dev University -Amritsar (GNDU), Maharshi Dayanand University – Rohtak (MDU), and Bhagat Phool Singh Mahila Vishwavidyalaya – Sonipat (BPSMV) were included in the study and Grey Box penetration testing method through open-source software’s Whois.sc, Yougetsignal.com, Kali Linux, Builtwith.com, NMAP, and Google Hacking Database (GHDB), etc. along with social engineering testing through external penetration strategy was applied to assess the ambiguity and vulnerability of HEIs. Findings:The analysis revealed that login IDs and passwords related to web portals, eResources, networks, etc. are freely available and shared without any authorization which is a major cause of security breach. The vulnerability test depicted unencrypted communication between the HEIs portals and servers and the absence of well-articulated security and privacy. Novelty: The study exhibits the lenient view of HEIs administration towards security aspects of G2C eGovernance projects and the outcome would enable the HEIs of India to develop a comprehensive security policy for enriching and securing the G2C eGovernance System. Keywords: eGovernance; security; ambiguity; vulnerability; privacy policy; social engineering testing

Estimation of discharge correction factor of modified Parshall flume using ANFIS and ANN

Purpose: To evaluate and compare the capability of ANFIS (Adaptive Neuro-Fuzzy-Inference System), ANN (Artificial Neural Network), and MNLR (Multiple Non-linear Regression) techniques in the estimation and formulation of Discharge Correction Factor (Cd) of modified Parshall flumes as based on linear relations and errors between input and output data. Design/methodology/approach: Acknowledging the necessity of further research in this field, experiments were conducted in the Hydraulics Laboratory of Civil Engineering Department, National Institute of Technology, Kurukshetra, India. The Parshall flume characteristics, associated longitudinal slopes and the discharge passing through the flume were varied. Consequent water depths at specific points in Parshall flumes were noted and the values of Cd were computed. In this manner, a data set of 128 observations was acquired. This was bifurcated arbitrarily into a training dataset consisting of 88 observations and a testing dataset consisting of 40 observations. Models developed using the training dataset were checked on the testing dataset for comparison of the performance of each predictive model. Further, an empirical relationship was formulated establishing Cd as a function of flume characteristics, longitudinal slope, and water depth at specific points using the MNLR technique. Moreover, Cd was estimated using soft computing tools; ANFIS and ANN. Finally, a sensitivity analysis was done to find out the flume variable having the greatest influence on the estimation of Cd. Findings: The predictive accuracy of the ANN-based model was found to be better than the model developed using ANFIS, followed by the model developed using the MNLR technique. Further, sensitivity analysis results indicated that primary depth reading (Ha) as input parameter has the greatest influence on the prediction capability of the developed model. Research limitations/implications: Since the soft computing models are data based learning, hence the prediction capability of these models may dwindle if data is selected beyond the current data range, which is based on the experiments conducted under specific conditions. Further, since the present study has faced time and facility constraints, hence there is still a huge scope of research in this field. Different lateral slopes, combined laterallongitudinal slopes, and more modified Parshall flume models of larger sizes can be added to increase the versatility of the current research. Practical implications: Cd of modified Parshall flumes can be predicted using the ANNbased prediction model more accurately as compared to other considered techniques. Originality/value: The comparative analysis of prediction models, as well as the formulation of relation, has been conducted in this study. In all the previous works, little to no soft computing techniques have been applied for the analysis of Parshall flumes. Even the regression techniques have been applied only on Parshall flumes of standard sizes. However, this paper includes not only Parshall flume of standard size but also a modified Parshall flume in its pursuit of predicting Cd with the help of ANN and ANFIS based prediction models along with MNLR technique

Engineering education system between Indonesian Vocational School and Japanese KOSEN

International partnership has become an emerging issue in which due to globalization goals, the needs of having collaboration between countries are inevitable. Cross-continents collaborations are encouraged; however, having partners with similar cultural background is seen more beneficial. This article aims to review challenges on programme development of Vocational Education between Indonesian and Japan. Vocational Education in Indonesia has been well established for decades where students are trained in 3-year education of Vocational High School then continue to 3-year education of Vocational School at the University. Curriculum is set to be more giving practical training which can enhance skills of students in problem solving. Moreover, KOSEN is one of distinctive education systems in Japan which is an abbreviation of Japanese form “koku-ritsu-kou-gyou-KOU-tou-SEN-mon-gak-kou” which is translated as National Institute of Technology. It offers 5-year education after Junior High School which provides training and skills development for students. Programme development of KOSEN and Indonesian Vocational Education are seen to be feasible for being implemented further which can deliver more skilful graduates. Combination of skills and cultural side of graduates are expected to be positively influencing their working ethics. Comprehensive capability of graduates is linear to their competency which also increases their employability.
