Time-frequency represetation of radar signals using Doppler-Lag block searching Wigner-Ville distribution

Radar signals are time-varying signals where the signal parameters change over time. For these signals, Quadratic Time-Frequency Distribution (QTFD) offers advantages over classical spectrum estimation in terms of frequency and time resolution but it suffers heavily from cross-terms. In generating accurate Time-Frequency Representation (TFR), a kernel function must be able to suppress cross-terms while maintaining auto-terms energy especially in a non-cooperative environment where the parameters of the actual signal are unknown. Thus, a new signal-dependent QTFD is proposed that adaptively estimates the kernel parameters for a wide class of radar signals. The adaptive procedure, Doppler-Lag Block Searching (DLBS) kernel estimation was developed to serve this purpose. Accurate TFRs produced for all simulated radar signals with Instantaneous Frequency (IF) estimation performance are verified using Monte Carlo simulation meeting the requirements of the Cramer-Rao Lower Bound (CRLB) at SNR > 6 dB

Investment, Hysteresis, and Layers of Techniques: A Case Study of Agricultural Manufacturing Machinery in Multan Division

The behaviour of firms is still a little understood matter. Why one firm or industry is investing more than the other or what makes a firm enter or exit from the market, what are the psychological factors that go to make a choice of this kind are questions that have not been answered satisfactorily. Concepts like irreversibility, uncertainty, investment, and the value of waiting are very much there in the literature, e.g., McDonald and Siegel (1985, 1986); Nickell (1974); Schmalensee (1972); Hartman (1972); Henry (1974) and LAM (1989) and others. But the psychology of decision-making on the face of losses has not received much attention in the literature. That the Economic Hysteresis1 and Layers of Techniques2, developed by Professor A. Dixit and Professor P. N. Mathur respectively tackle.

Corporate environmental performance and its impact on financial performance and financial risk: Evidence from Australia

This thesis consists of four essays on Corporate Environmental Performance (CEP) and its impact on Corporate Financial Performance (CFP). The first essay is entitled “Emission Indices for Hazardous Substances: An Alternative Measure of Corporate Environmental Performance”. This essay reviewed significant interdisciplinary research and concluded that firm chemical release/emission can be used as a proxy for a firm measure of environmental performance. It also proposed that due to the variety of chemicals and different levels of toxicity, a risk factor should be calculated for all chemicals on the basis of human health risk, environment risk and risk of exposure. Once a single risk factor is calculated for each chemical, then it should be multiplied by the level of each company chemical release that is reported to National Pollutant Inventory in order to calculate the weighted average risk factor for each company. Thus, the weighted average risk is a robust measure having the combined effect of level of toxicity and volume of chemical emissions. Once the environmental performance index is formulated, the second essay investigated the nature of the relationship between environmental performance and financial performance of publicly listed companies in Australia. The second essay provided evidence that the nature of the relationship between environmental performance and financial performance is positive. Further, this study divided the sample into a period of economic growth (2001-2007) and a period of economic contraction (2008-2010). The multivariate regression estimation shows a positive relation between CEP and CFP in the period of economic growth but during the extra ordinary circumstances like the financial crisis this relationship is insignificant. This research is of great relevance for managers, academics and society at large. The third essay investigates the relationship between Corporate Environmental Performance (CEP) and financial risk for Australian listed companies from 2001-2010. Three financial risk measures including firm market risk, systematic risk and downside risk were used. The analytical procedure based on fixed effects estimation provides strong evidence that environmental performance is negatively and statistically associated with market volatility and to different measures of downside risk. The third essay results show that downside risk is a better measure of firm risk especially when investors are not showing linear sensitivity to changes in prices. Therefore, this study concludes that environmental performance (reduction in toxic emissions) provides a wealth protection effect. The results are robust after controlling for several moderating effects including financial, institutional and environmental management. The fourth essay analyses the causal relationship between firm financial performance and environmental performance. The results provide convincing support for the idea that there is a bi-directional relationship between CEP and CFP in both the short and long run. These results support the Hart and Ahuja (1996) hunch that a ‘virtuous circle’ exists with regard to the relationship between pollution prevention and CFP, that is, firms can realize cost savings and plough these savings back into further emission reduction projects for a number of years before the benefits balance turns negative

Mixture of CO2-N2 as a potential to SF6 insulation gas: an overview

Each equipment in the high voltage (HV) system must retain an appropriate electrical insulation for protection and to avoid any of leakage current [1]. Thus, the choice of insulation material is essential. There are three types of insulation medium which is gases, liquids, and solids. Previous research claims that at normal temperature and pressure, gas insulation was an excellent insulator. An excellent gaseous dielectric material, however, required a long list of demanding properties, for example, having an utmost dielectric strength, good heat transfer, environmental-friendly, high thermal constancy, and available at low cost
