Adaptation Of Watt’s Indicator Mechanism In Altitude Measurement

In today’s world, air travel has become the primary mode of fast and reliable transport. In fact, in the broad arena of international travel, air travel has established itself as the one and only mode of transportation. More and more aircraft operators are getting into business each and every year and the competition is fierce. In this situation, it is but natural to expect safe transportation and involvement of better technologies to dispel fears among the general public regarding air travel. We can confidently say that the number of incidents and accidents involving aircrafts have come down than it used to be in the 19th century and that the 20th century has seen aircrafts evolving using high end technologies to fight against any problems that nature or machine can throw up on the aircraft and in turn, the crew. In fact, we can be firm in saying that air travel is the safest mode of transportation

Optimal jammer placement to interdict wireless network services

The demand for wireless networks continues to grow as the need for portable, low-cost telecommunications systems increases around the world. Wireless networks are particularly complex because their topologies can change in response to operational requirements or environmental conditions and also because wireless networks are susceptible to electromagnetic interference. In this thesis, we consider the challenges associated with the operation and jamming of so-called "wireless mesh networks." In a wireless mesh network, the communication devices (denoted here as a nodes) are uniform in their ability to send and receive transmissions. We formulate and solve two related optimization problems for wireless mesh networks. First, we solve the problem of the network operator, namely: In order to maximize the utility of delivered network traffic, how should one set the power transmission levels for each node, and along what sequence of transmission links should the traffic flow? The second problem we consider involves an intelligent adversary, the attacker, who wants to place jamming devices among a finite number of locations to disrupt the operator's traffic in the worst possible way. We formulate and solve mathematical programs to obtain the optimal operation and jamming of these networks. We develop a computational decision-support tool that affords the rapid reconfiguration and analysis of various deployment scenarios.http://archive.org/details/optimaljammerpla109454012US Marine Corps (USMC) author

Effectiveness of Precision-guided Munitions on Armour Systems

Simulation methodology has been used to analyse the effectiveness of multi-barrel rocketlauncher system (MBRLs) delivering precision-guided munitions (PGMs) on armour forcedeployed in concentration areas under various terrain conditions. The methodology considersvarious aiming strategies, the effectiveness of the sensor and the imprecision in informationavailable about the target to evaluate the effectiveness of the MBRL system

Measurement of health system performance at district level: A study protocol

Background: Limited efforts have been observed in low and middle income countries to undertake health system performance assessment at district level. Absence of a comprehensive data collection tool and lack of a standardised single summary measure defining overall performance are some of the main problems. Present study has been undertaken to develop a summary composite health system performance index at district level. Methods: A broad range of indicators covering all six domains as per building block framework were finalized by an expert panel. The domains were classified into twenty sub-domains, with 70 input and process indicators to measure performance. Seven sub-domains for assessing health system outputs and outcomes were identified, with a total of 28 indicators. Districts in Haryana state from north India were selected for the study. Primary and secondary data will be collected from 378 health facilities, district and state health directorate headquarters. Indicators will be normalized, aggregated to generate composite performance index at district level. Domain specific scores will present the quality of individual building block domains in the public health system. Robustness of the results will be checked using sensitivity analysis. Expected impact for public health: The study presents a methodology for comprehensive assessment of all health system domains on basis of input, process, output and outcome indicators which has never been reported from India. Generation of this index will help identify policy and implementation areas of concern and point towards potential solutions. Results may also help understand relationships between individual building blocks and their sub-components

Retrospective analysis of clinical and radiological outcome of exeter cemented total hip arthroplasty 2000 - 2010.

OBJECTIVES : To analyse the clinical and radiological outcome of Exeter cemented total hip arthroplasty. METHODS : 1. Clinical outcome was analysed with Harris Hip Score. 2. To analyse the Radiological outcome as follows. a. Immediate post op Cement mantle thickness. b. Cement filling within the medullary canal. c. Orientation of femoral prosthesis within the cement mantle. d. Follow up xrays for radiological features of loosening. 3. Pearson Chi square test and Fischers exact test were used to correlate the significance among the variables. RESULTS : 1. In our study of 47 hips we had excellent - 65.96% ; Good- 21.28% ; Fair – 8.51% and poor- 4.26% results. 2. There were no cases of femoral stem loosening (0%) , 1 case (2.1%) of acetabular cup loosening and 1 case of dislocation (2.1%). 3. There was significant correlation between cement thickness and Gruen’s loosening zones. 4. There was no significant correlation between cementing technique and orientation of stem with proximal femoral resorption and loosening in Gruens zones. 5. Second generation of cementing technique produced 82.92% grade A; 14.89% grade B; 0% in grade C and 2.13% grade D which also did not have a correlation with stem revision

Development of a dynamic shortest path algorithm and a traffic simulation model

Shortest path determination in a dynamic transportation network has been a real challenge where network traffic scenario changes continuously. The shortest path between any two nodes in the network depends not only on the travel time of links that constitutes the path but also on the time spent at the intersection which is a major part of the trip time. Existing algorithms found in the literature consider only the link travel time for the shortest path calculation between two nodes. A new algorithm is introduced in this study that calculates the dynamic minimum trip time path between two nodes by considering both link travel time and intersection turning delay. A macroscopic traffic simulator is developed to simulate vehicles that use the proposed algorithm to calculate the minimum trip time path. The trip time of guided vehicles which determine the travel path based on en-route traffic information is compared to the trip time of unguided vehicles which determine the travel path based on pre-trip traffic information. The guided vehicles are assumed to be a part of a decentralized traffic management system where onboard route guidance system allows the driver to calculate the minimum trip time path each time they cross an intersection. A part of Montréal city road network is also simulated to show the application of proposed path finding algorithm. From the results it is seen that for a long distance trip the amount of trip time savings is higher because the guided vehicles usually choose the path with less number of left turning delays

Simultaneous cellulose hydrolysis and bio-electricity generation in a mediatorless Microbial Fuel Cell using a Bacillus flexus strain isolated from wastewater

The ability of electrochemically active bacteria to degrade natural wastes suggests a wide array of applications for waste management as well as electricity generation. This study reports the results of an experimentation where five bacteria were isolated from waste water and the electrochemical activity of one of them was confirmed by their use in a Microbial Fuel Cell. The bacterium was identified to be Bacillus flexus with a 99% similarity to the IFO 15715 strain using partial 16S rDNA sequencing. Phylogenetic analysis based on the BLAST results indicated close proximity to Bacillus megaterium, a known exoelectrogen
