The need to diversify power generation sources, increase security of supply, incorporate sustainability in energy sources and reducing fuel usage and emissions has significantly led to the integration of variable renewable energy sources such as wind to power grids globally. Kenya, for instance, targets to increase wind power generation to 2,000 MW by 2031. However, increased integration of wind power into a grid necessitates the need to update unit commitment and operating reserve algorithms since wind power is highly variable, intermittent and non-dispatchable. In this book, the effects of increased wind power generation on the power system spinning reserve resource requirements were analyzed. Simulations for this research were conducted in MATLAB/Simulink environment. Monte Carlo Simulations were performed by use of the Unit Commitment formulation method and a probabilistic approach so as to analyze the amount of spinning reserve resource required and the optimal cost of operation for a model having three different levels of wind power generation: 20MW, 40MW and 60MW. Finally, the spinning reserve resource requirements were quantified for the three different levels of wind power

A routing technique is proposed which incorporate device residual battery power status into routing path selection decision with the objective to maximize the energy efficiency in the selected routing path. A new path selection metric is also taken into account based on probabilistic approach. The issue of congestion is addressed as congestion is also one of the main reasons for packet drops in mobile adhoc network at high load. To achieve optimal network performance with energy efficiency, the congestion issue must be addressed together with energy issue. The proposed protocol is further enhanced with addition of congestion adaptability, which further enhances the energy efficiency of the network and at the same time give better network performance. Sleep mode is also added in the proposed protocol to save the node energy if the node is already in low power state.The cross layer design approach is further incorporated in the proposed protocol to address the issue of node mobility using link monitoring and adding the functionality of dynamically controlled variable transmission power to save node energy.

This study provides a critical review of the effects of political risk and macroeconomic factors on stock market performance in Kenya. The study was undertaken due to the country's increasingly volatile political environment following the 2007/2008 political violence that rocked the country as a result of the fiercely contested presidential elections in addition to the erratic movement in key macroeconomic variables in the Kenyan economy. Unlike previous studies that analysed the impact of political risk on stock returns in isolation, this study seeks to incorporate key macroeconomic variables such as interest rates, money supply, exchange rates, crude oil prices and inflation rate for a holistic analysis. The main objective of the study is to determine the effects of political risk and macroeconomic factors on stock market returns at Nairobi Securities exchange, in addition the effects of each independent variable on the stock market returns at Nairobi securities exchange is determined, The study will not only be of importance to the investors seeking to invest at NSE by helping them understand how political risk and key macroeconomic variables affect the market performance.

High Quality Content by WIKIPEDIA articles! The Mercedes-Benz DiesOtto is an experimental automobile engine that is said to incorporate the benefits of a diesel engine, but runs on regular old unleaded. Its name is a portmanteau of Diesel and Otto, referring to the Diesel engine, first introduced by German engineer Rudolf Diesel, and the Otto cycle, as a reference to Nicolaus Otto (even though the invention of the gasoline engine is variously attributed to both Nicolaus Otto and Alphonse Beau de Rochas). The concept engine has an in-line, four-cylinder configuration and displaces 1.8 litres. Its peak power is no less than 175 kW (235 hp), making its specific output 97 kW/L (130 hp/L), and its peak torque is 400 N m, making its specific torque 220 N m/L. Mercedes-Benz do not specify the RPM at which these specified maxima are reached. The DiesOtto features the following: HCCI (Heterogeneous Charge Compression Ignition), variable valve timing, twin variable geometry turbocharging, variable compression ratio, direct fuel injection.

High Quality Content by WIKIPEDIA articles! EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. Unlike its predecessor the ENIAC, it was binary rather than decimal, and was a stored program machine.ENIAC inventors John Mauchly and J. Presper Eckert proposed the EDVAC's construction in August 1944, and design work for the EDVAC commenced before the ENIAC was fully operational. The design would implement a number of important architectural and logical improvements conceived during the ENIAC's construction and would incorporate a high speed serial access memory.

Despite the fact that credit risk is proven to be one of the most important determinants of the net interest margin (NIM), it was never proxied by probability of default in the previous papers. The primary goal of this research is to develop a model for PD estimations, and to incorporate this variable into the regression with NIM as a dependent variable. This paper examines the impact of PD on NIM of 35 Austrian banks, covering a fourteen-year period from 1999 to 2013. The statistical analysis suggests that PD can be estimated by using banks' financial statements. The ratios characterizing liquidity, assets, capital and profitability are used as explanatory variables in the regression model. Moreover, our results provide a good evidence that PD has a significant influence on NIM. The slope coefficient is negative when PD is used as the only explanatory variable for NIM, however, the sign is reversed when other bank-specific and macro factors are taken into account. Equity and operational efficiency variables as well as volatility of interest rates are found to be significant. At the same time, GDP growth and Inflation rate are irrelevant for NIM estimation in our research.

This work addresses investment strategies on Currency markets. One way to build up a robust strategy consists in using a parametric approach: maximizing the investor utility given different characteristics on the currencies available at the time. For such purpose, traditional elementary Carry trade strategies, Momentum strategies and Valuation strategies come in handy as characteristic signals for they exploit different stylized facts of the market. We discuss the possibility of an optimised multi-factor parametric investment strategy using these traditional strategies as building blocks. Moreover, we propose improvements to make the strategy reactive to distress across markets developing a regime-variable strategy: we define a variable to account for the "state of the world", and explain how to incorporate it to the parametric strategy. Eventually, calibration is the ultimate investor-friendly lever one needs to control his exposure to systematic risk.
