In modern aircraft, energy supply management has become a critical matter, since many aboard electrical loads have to be supplied, especially those related to flight safety. However, at the same time, the size and weight of electrical generators must be limited because of their on-board installation. In this paper, the Mixed Integrated Linear Programming (MILP) methodology has been used to formulate the Supervisor definition of the direct current (DC) microgrid (MG) on-board system with an extension for the programmable loads. Due to the problem of dimension increase, two methods have been presented and tested to perform optimal energy management (EM) aboard an aircraft: the Branch and Bound (B&B) and the Linear Regression Approximation (LRA). Finally, numerical simulations and results have been provided to validate the proposed optimization methodologies, according to the dimensions and the complexity of the problem.

Purpose – Alternative corporate governance systems (CGSs) have attracted a significant bulk of research recently. While the connection between the adoption of an alternative system (one tier board or two tier board system) and firms’ performances has not been fully analysed yet, the purpose of this paper is to analyse whether companies which have turned into an alternative board system have eventually improved their performance over time. Design/methodology/approach – Using a sample of more than 15,000 Italian unlisted joint stock companies, the authors compare performance outcomes in 2009 of firms adopting alternative systems with performances of firms that maintained the system in force before the 2003 Corporate Law Reform (defined as “traditional”). Because of the choice of an alternative system (one tier or two tier board) instead of a traditional one is not random, the authors reduce selection bias implementing matching methods and comparing firms that are close in terms of propensity score measured in 2003 (the year before the new CGSs have been introduced by a corporate law reform). Findings – The authors do not find evidence of a significant improvement of performances in 2009 concerning those firms that have adopted a one tier or two tier board systems with respect to those which maintained a traditional one. Originality/value – The novelty of the study concerns the application of propensity score matching for the evaluation of the impact of the change of the CGS that is possible in presence of two conditions that are all verified in our setting: first, to have a country where corporate law allows for choosing among different systems; in this case Italy is a good laboratory, because it allows for the choice among three different systems; and second, to have the opportunity to evaluate the effect of the change in light of a relatively recent “pre-treatment” condition; this is made possible by the fact that before the 2003 Reform of corporate law all the companies had a traditional system.

Board System

With the growth with the citys population of elderly people, the symptoms of aging are becoming more and more significant. Older people are faced with complex circumstances when they are outdoors, a correct and efficient system of road signs should help them reach their destinations safely. Therefore, a well designed system for the elderly is vital. The following research is concentrated on the design of the road sign system focusing upon the aspects of placement positions, height of the text and symbols, and the amount of information included on the sign. This will assist in the design of the most useful and efficient sign board system for the elderly. This will be determined through the experimental method.
