The purpose of this paper is to evaluate the worst-case behavior of a given electronic circuit by varying the values of the components in a meaningful way in order not to exceed pre-defined currents or voltages limits during a transient operation.

An analytic formulation is used to identify the time-dependent solution of voltages or currents using proper state equations in closed form. Circuits with linear elements can be described by a system of differential equations, while circuits composing nonlinear elements are described by piecewise-linear models. A sequential quadratic program (SQP) is used to find the worst-case scenario.

It is found that the worst-case scenario can be obtained with as few solutions to the forward problem as possible by applying an SQP method.

The SQP method in combination with the analytic forward solver approach shows that the worst-case limit converges in a few steps even if the worst-case limit is not on the boundary of the parameters.

Based on the importance of E-accounting, the purpose of this study is to investigate the determinants influencing information technology and E-accounting among small and medium-sized enterprises (SMEs).

A survey method was used to select the sample among SMEs in Oman. Using descriptive statistics, the impact of the determinants on E-accounting practices in SMEs in Oman were tested.

The findings reveal that except information technology (IT) cost, all other possible determinants (IT risk, employee IT skills and employee theoretical knowledge) has a significant influence on E-accounting practice among SMEs.

The link between variables of this study was not analyzed in Oman. Moreover, this study only concentrated on the impact of the fourth determinants, while in reality, there must be other determinants that should also be investigated by other researchers.

This study has added to the literature by examining the E-accounting practices while evaluating the effect of IT determinants on the relationship. Besides, this might add benefits to many SMEs relating to their current accounting practice that might lead to adopting E-accounting practice to ensure application of applicable accounting standards to show fair financial statements to its stakeholders.

This current study is one of the first works in the context of Oman. It has added a new discussion to the body of knowledge in light of the IT determinants and their relationship with E-accounting practices; hence, an approach that is not widely discussed in the literature. Furthermore, conducting such research in the field of accounting provides new insight into the literature among both emerging and developed economies including Oman.
