Real-Time System: Fire and Smoking Control System (Case Study)
Muhammed Ali Suliman Mesleh,Mohammed Ashraf Zoghoul
World of Computer Science and Information Technology Journal , 2013,
Abstract: A real-time system is software where the correct functioning of the system depends on the results produced by the system and the time at which these results are produced. The main objective of this study is to show the importance of real-time system as an application that uses computer system in the human life. Since it helps to control vital and dangerous aspects, that otherwise can not be controlled.The motivation for this study is to avoid fire occurrence and smoking habits in certain places. Since by using this system the place and time of event can be determined in short period. For that reason, the need for using real-system raised.

SUBHASH CHANDER,DR. TK JINDAL
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: Automated Fire control Systems (AFCS) is a sophisticated and critical segment of a typical Pulse detonation engine (PDE) rig. The relevant standards, safeties and redundancies were built by design to achieve successful missions. Primary emphasis is placed on the methodical approach required in the design of modernAFCS. This approach involves thorough analysis of the particular fire control problem at hand, establishment of the most suitable mathematical model, and computerization and realization of the built mathematical models through LABVIEW.Thedesigned system was analysed rigorously validated against specifications. It was also tested in live firing after going through various qualifications/ verifications during various stages of development. The unit is operating satisfactory and proved its reliability during 70+ firings and will be utilized for future firings with enhanced capabilities.

Toxicity and Efficacy of Two Emulsifiable Concentrates of 2-Tridecanone against Red Imported Fire Ants  [PDF]
Jian Chen
Advances in Entomology (AE) , 2016, DOI: 10.4236/ae.2016.41006
Abstract: 2-tridecanone is a major constitute of defensive secretion in tawny crazy ants, Nylanderia fulva that is an ant species reported to be able to displace red imported fire ants, Solenopsis invicta in the field. 2-tridecanone was proven to be toxic to S. invicta. Although 2-tridecanone is commercially available, utilization of this naturally occurring compound in fire ant management has received little attention. In this study, toxicity and efficacy of two 2-tridecanone formulations were assessed against S. invicta. Two emulsifiable concentrates were prepared using 2-tridecanone as an active ingredient, vegetable oil as a solvent and polyoxyethylene tridecyl ether as a surfactant. Piperonyl butoxide (PBO) was used as a synergist in one formulation. Both formulations showed significant toxicity in laboratory bioassays. In a field trial, at application rate of 5.28 mL/L and 14 days after mound drench treatment, 100% control was achieved for formulation with PBO and 90% control for the formulation without PBO. In conclusion, both formulations had significant efficacy against S. invicta. Due to the low mammalian toxicity of 2-tridecanone, no involvement of hazardous synthetic organic solvents, no phytotoxicity at applied concentrations, and relatively low cost, both formulations are promising alternatives to commercial insecticide products for fire ant mound drench. The outstanding efficacy of both formulations observed in this study warrants further research on their efficacy against other pest insects.
Plain cigarette packaging: A policy analysis of Australia’s integrated “whole-of-system” model for smoking cessation  [PDF]
Lorraine Davies, Erica Bell
Health (Health) , 2012, DOI: 10.4236/health.2012.412187
Abstract: Introduction: Plain cigarette packaging as a tobacco control measure is to be implemented in Australia on December 1st 2012. There is mounting evidence for its likely impact on smokers and potential smokers. Yet Australia’s integrated model of smoking cessation and the particular role and opportunities it has created for primary healthcare have not yet been subject to policy analysis in leading international journals. This policy analysis paper explores these new Australian policy developments and debates in ways that identify their international relevance to primary healthcare. Policy analysis: There are 57 studies about plain cigarette packaging published since 2002. Of these, 27 looked at the impact of health warnings. These studies support the introduction of plain packaging as a tobacco control measure, by increasing the efficacy of health warnings and reducing misconceptions about cigarettes. However, the Australian tobacco control reforms are not limited to plain cigarette packaging. They include other evidence-based tobacco control measures as part of its primary health care strategy: for example, increasing tobacco excises, a mass media campaign focusing on high-risk and hard-to-reach groups, and a national summit on smoking in prisons. The Australian government has acknowledged the key role of primary health care in health promotion activities, establishing a network of regional primary health care organisations (“medicare locals”) in 2011-2012, and expanding the role of nurses in general practice. These initiatives offer general practice a chance to seize “golden opportunities to intervene with smoking patients”. Conclusions: Whether the combined impact of the Australian government’s recent tobacco control reforms and its previous measures will be sufficient to reduce daily smoking prevalence to 10% or less by 2020, only time will tell. What is more certain is that the Australian experience of plain packaging offers international colleagues in general practice key lessons about the importance of “whole-of-system” approaches, integrating efforts at the local to national levels, to tackle smoking cessation. The achievement of Australia’s political leaders in plain cigarette packaging is an extraordinary testament to political will but there is no room for complacency. Primary healthcare sectors must continue to lobby political leaders around the world to tackle smoking at the system level where the motivations and beliefs about smoking are being shaped, especially among disadvantaged groups with lower health literacy.
Mathematical Modeling of Crown Forest Fire Spread  [PDF]
Valeriy Perminov
Open Journal of Forestry (OJF) , 2012, DOI: 10.4236/ojf.2012.21003
Abstract: Mathematical model of forest fire was based on an analysis of known experimental data and using concept and methods from reactive media mechanics. In this paper the assignment and theoretical investigations of the problems of crown forest fire spread in windy condition were carried out. In this context, a study—mathematical modeling—of the conditions of forest fire spreading that would make it possible to obtain a detailed picture of the change in the temperature and component concentration fields with time, and determine as well as the limiting condition of fire propagation in forest with fire break.

CERNE , 2012,
Abstract: This research mapped forest fire risk for Novo Mundo County, located between the coordinates 09o09′29”S, 49°58’59”W and 10°29’28”S and 48o55′52” W, Mato Grosso State, Brazil. Using Geo-processing techniques individual risk maps for hydrograph, roads, slope and soil use and cover were elaborated. The risks were classified as null, low, high, very high, and extreme level. Afterward, the individual maps were overlaid by Overlay technical, resulting in a final fire risk zoning map. The results showed that 95% of the studied area was under high and very high risks. The variables that most influenced the risk were the boundary areas of vegetation with roads, roads with pasture and pastures and vegetation.

Abstract: Renovation of networked campaign modality results in the development of networked antiaircraft fire control system. Based on the networked antiaircraft campaign, the architecture of networked antiaircraft fire control system and the method of track fusion are investigated. Theories of networked control system are introduced to the research of the architecture of networked antiaircraft fire control system and the practical construction of such systems. In order to reach better efficiency under the architecture, research on track fusion problems is also studied. Track fusion based on Federated Kalman filter technique is put forward, and the structure of the filter is designed for the flexible and open architecture. Local filter can deal with packet losses and time-delay according to network transmission status. Experiments are performed and the results show that data precision is greatly improved by the fusion. The method could be a strong foundation for the design and implementation of networked antiaircraft fire control system.

With the application of information technology to the military field, the advantages of information-based military operations based on network-centric warfare theory become more obvious. The deployment of firepower units is a key issue in networked military operations, which involves how to substantially apply the limited resources to maximize the defending abilities of the firepower units. It is one of the non-linear optimization issues with multiple constraints. The deployment optimization of firepower units (DOFU) and their approaches in networked fire control system (NFCS) are reviewed in this paper. Firstly, the fundamental research status of DOFU is reviewed. Secondly, the mathematical model of the deployment of firepower unit is summarized based on three aspects including deployment space, constraints and objective function. Besides, research progress of DOFU methods, which consist of encoding, constraints-handling, multiobjective- handling and the algorithm, is discussed. Finally, the conclusions of the key issues and the development trend of DOFU are elaborated.
