Design and Feasibility Analysis of conventional planar antennas as chipless RFID strain sensors
2015 International Symposium on Antennas and Propagation (ISAP), 2015Co-Authors: Nemai Chandra KarmakarAbstract:This paper focuses on the design and Feasibility Analysis of conventional planar antennas as chipless RFID strain sensors. A number of printed monopole and dipole antennas are designed and their structural deformation due to different types of applied strain is theoretically analyzed. This theoretical deformation results are used to calculate the corresponding resonance frequency and quality factor deviation to determine the maximum amount of strain the antennas can handle. Thus a novel Analysis is presented to determine the acceptability of the designed antennas as strain sensors.

Chipless RFID strain sensors: A novel Feasibility Analysis in terms of conventional patch antennas
2015 IEEE MTT-S International Microwave and RF Conference (IMaRC), 2015Co-Authors: Nemai Chandra KarmakarAbstract:This paper focuses on the design and Feasibility Analysis of conventional microstrip patch antennas as chipless RFID strain sensors. Three sensing antennas with different substrates are designed and their structural deformation due to different types of applied strain is theoretically analyzed. These theoretical deformation results are used to calculate the corresponding resonance frequency and quality factor deviation to determine the maximum amount of stress the antennas can tolerate. Thus a novel Analysis is presented to determine the acceptability of the designed antennas as strain sensors.

Investment Feasibility Analysis of rainwater harvesting in a building in Brazil
Water Science & Technology: Water Supply, 2017Co-Authors: Enedir Ghisi, L. P. Thives, R. F. W. PaesAbstract:The objective of this study is to assess the investment Feasibility Analysis of rainwater harvesting in a building located in Brazil. Rainwater was used to supply toilets, cleaning and irrigation. The costs of materials, labour and maintenance were obtained to carry out the economic Analysis; the indicators used were the net present value, internal rate of return and payback period. The investment Feasibility Analysis and the potential for potable water savings were obtained by means of computer simulation. The potential for potable water savings ranged from 26.70% to 64.70%. The net present value, internal rate of return and payback period for the best scenario were, respectively, R$ 132,801.47, 3.73% per month and 32 months. For the worst scenario the net present value was R$ 9,451.26, the internal rate of return was 0.91% per month and the payback period was 166 months. Thus, rainwater can be used as a sustainable alternative and be financially feasible.

Investment Feasibility Analysis of Rainwater Use in Residences
Water Resources Management, 2013Co-Authors: Enedir Ghisi, Pedro Neves SchondermarkAbstract:This paper presents an investment Feasibility Analysis of rainwater harvesting systems for the residential sector in Santa Catarina State, southern Brazil. Five towns were selected for the Analysis. Daily rainfall data, average water consumption, rainwater tank costs, water pump costs, and water, sewage and electricity tariffs were obtained for the five towns. Different values for the roof area, number of residents, potable water demand, and rainwater demand were analysed. The rainwater tank capacities were estimated using the Netuno computer programme. The investment Feasibility Analysis was performed considering the ideal lower tank capacity, as well as capacities smaller and larger than the ideal. Such capacities were obtained according to a variation of six months in the payback period. It was observed that the ideal tank capacity can be conservative for high rainwater demands. In such cases, an investment Feasibility Analysis should be performed in order to obtain a more appropriate tank capacity. The main conclusion is that rainwater usage is economically feasible for most cases; and the higher the rainwater demand, the higher the Feasibility.

rainwater harvesting in petrol stations in brasilia potential for potable water savings and investment Feasibility Analysis
Resources Conservation and Recycling, 2009Co-Authors: Enedir Ghisi, Davi Da Fonseca Tavares, Vinicius Luis RochaAbstract:Abstract Rainwater harvesting is an important way of optimizing the usage of water resources and promoting sustainable development. The objective of this article is to evaluate the potential for potable water savings by using rainwater for washing vehicles in petrol stations located in Brasilia, Brazil. An investment Feasibility Analysis was also performed. The study was carried out by using Neptune, a computer programme for rainwater harvesting Analysis. Rainfall data from two meteorological stations were considered, as well as different rainwater collecting areas, tank capacities, number of washings, and potable and rainwater demands. As for the rainwater demands, they were considered as a percentage of the potable water demand, varying according to the day of the week. The tank capacities were varied at increments of 1000 L. The investment Feasibility Analysis was performed for three different cases, taking into account the potential for potable water savings. It was observed that the average potential for potable water savings by using rainwater is 32.7%, but it can vary from 9.2% to 57.2%. The main conclusion obtained from this work is that using rainwater for washing vehicles in petrol stations in Brasilia is a feasible investment for most cases as the net present value is positive for an interest rate of 1% per month.

Feasibility Analysis for Temperature-Constraint Hard Real-Time Periodic Tasks
IEEE Transactions on Industrial Informatics, 2010Co-Authors: Gang Quan, Vivek ChaturvediAbstract:While the dynamic thermal management problem is closely related to the dynamic power management problem, it has its own distinct features. In this paper, we study the Feasibility checking problem for real-time periodic task sets under the peak temperature constraint. We show that the traditional scheduling approach, i.e. to repeat the schedule that is feasible through the range of one hyperperiod, does not apply any more. We then present new necessary and sufficient conditions to check the Feasibility of real-time schedules. We further incorporate the close relationship of leakage, temperature, and supply voltage into our Feasibility Analysis, and develop more elaborated Feasibility conditions. Our experiments, based on technical parameters derived from a processor using the 65 nm IC technology, demonstrate the effectiveness of our Feasibility conditions and, at the same time, highlight the fact that a power/thermal-aware computing technique becomes ineffective at the submicron scale if the inter dependency of leakage, temperature, and supply voltage is not properly addressed.
