DRedSOP: Synthesis of a new class of regular functions
No full textIn this paper we characterize and study a new class of regular Boolean functions called D-reducible.A D-reducible function, depending on all its input variables, can be studied and synthesized in a space of dimension strictly smaller than . A D-reducible function can be efficiently decomposed, giving rise to a new logic form, that we have called DRedSOP. This form is shown here to be generally smaller than the corresponding minimum SOP form. Experimental evidence shows that such functions are rather common and D-reducibility can be tested very quickly
Complete and efficient methods for supporting side effects in independent/restricted and-parallelism
No full textIt has been shown that it is possible to exploit Independent/Restricted And-parallelism in logic programs while retaining the conventional "don't know" semantics of such programs. In particular, it is possible to parallelize pure Prolog programs while maintaining the semantics of the language. However, when builtin side-effects (such as write or assert) appear in the program, if an identical observable behaviour to that of sequential Prolog implementations is to be preserved, such side-effects have to be properly sequenced. Previously proposed solutions to this problem are either incomplete (lacking, for example, backtracking semantics) or they force sequentialization of significant portions of the execution graph which could otherwise run in parallel. In this paper a series of side-effect synchronization methods are proposed which incur lower overhead and allow more parallelism than those previously proposed. Most importantly, and unlike previous proposals, they have well-defined backward execution behaviour and require only a small modification to a given (And-parallel) Prolog implementation

A hybrid network IDS for protective digital relays in the power transmission grid
No full textIn this paper, we propose a novel use of network intrusion detection systems (NIDSs) tailored to detect attacks against networks that support hybrid controllers that implement power grid protection schemes. In our approach, we implement specification-based intrusion detection signatures based on the execution of the hybrid automata that specify the communication rules and physical limits that the system should obey. To validate our idea, we developed an experimental framework consisting of a simulation of the physical system and an emulation of the master controller, which serves as the digital relay that implements the protection mechanism. Our Hybrid Control NIDS (HC-NIDS) continuously monitors and analyzes the network traffic exchanged within the physical system. It identifies traffic that deviates from the expected communication pattern or physical limitations, which could place the system in an unsafe mode of operation. Our experimental analysis demonstrates that our approach is able to detect a diverse range of attack scenarios aimed at compromising the physical process by leveraging information about the physical part of the power system
Secondary Filtration of Closed Loop in DC Locomotive
No full textThe use of hydraulics has increased tremendously in the recent past due to the various advantages it provides such as high power to weight ratio, elimination of complex components, ease of transportation and safety to name a few. Moreover the main advantage that hydraulic locomotives provide over conventional locomotives is constant velocity. Though there are various advantages to using hydraulics, contamination of working fluid poses a severe threat to components such as premature wear of components, a corrosion of components which would require replacing them well before their life incurring significant loss. Contamination of hydraulic fluids cannot be prevented or eliminated but can be contained to a certain extent. The safe levels of contamination are arrived at by comparing to recommended oil cleanliness values defined by NAS. Even though hydraulic systems are provided with an in built filter known as primary filter to remove solid or particulate impurities at cleanliness value at recommended levels. The controlling of contamination levels in the hydraulic oil by use another filtration unit externally, will reduce the level of contamination significantly and increases the life of the hydraulic drive system. To monitor the level of contamination of various sizes closely, a particle counter added to the additional unit proves to be beneficial. This project investigates the change in level of contamination in the working fluid after addition of the secondary filtration unit. Dr. K Muthukumar | V.

Role of systemic antibiotic prophylaxis in acute burns: A retrospective analysis from a tertiary care center
No full textIntroduction: Burns is a worldwide problem, majority of them occurs in low and middle-income countries. The hurdles in treatment of burns in the resource restricted setting are much unique and challenging. The role of intravenous antibiotics in reducing mortality and morbidity related to infection and sepsis has not been studied extensively in the Indian sub-continent. Materials and methods: This was a retrospective study that was conducted at a tertiary burn care centre in India over a period of six months with follow up of one month from the day of burn injury. Results: Data from a total of 157 patients were collected and analysed. In Prophylaxis group (n = 77), sepsis was detected in 33 patients and 38 patients expired. In No Prophylaxis group (n = 80), sepsis was detected in 37 patients and 40 patients expired. In Inhalational burns subgroup, patients belonging to prophylaxis group (n = 30) had 20 patients diagnosed with pneumonia while 22 patients did not survive till 30th post burn day. Patients in No Prophylaxis group who had inhalational burns were 38 in number. Pneumonia was diagnosed in 29 of them while 27 did not survive till 30th post burn day. In Pneumonia subgroup, patients belonging to Prophylaxis group had lower mortality rate as compared to No Prophylaxis group. Conclusion: Our study does not support the routine usage of antibiotic prophylaxis in patients with burn injuries, but their administration can be considered in certain specific subgroups like patients with inhalational burns and patients developing pneumonia. Pneumonia is an independent risk factor for mortality when no antibiotic prophylaxis is used in burn patients.No Full Tex

Introducing systems engineering to industrial design engineering students with hands-on experience
No full textThe article presents an innovative educational project to introduce systems engineering to third year students in industrial design engineering at the University of Twente. In a short period the students are confronted with new technology, namely sensors and actuators. They have to apply this technology in a complex situation, the design of a home climate system or an intelligent automobile. They work in large groups without tutor. In parallel a basic course on systems engineering is given to provide the students with tools for handling this situation. The aim is that students are forced to apply the systems engineering tools in a concrete situation, thus directly experiencing the benefits. The project is implemented and the article describes the context, the goals, the setup, and the experiences of both teachers and students. The article concludes with an evaluation of the first and second year it has been executed
