Very often it so happens that the cost of operating an Intrusion Detection System (IDS) exceeds the cost of purchasing the IDS itself. In such cases, regular operation and maintenance of the system becomes expensive. Thus, it becomes essential to reduce the operating cost of the IDS without compromising on the performance and reliability of the IDS. Apart from the initial cost of procuring the IDS, other costs include cost of accessories required and cost of administration etc. In this paper we calculate the cost benefit tradeoffs of an IDS. We propose a method to determine the optimum operating point of the IDS. In an effort to solve the problems of the previously proposed metrics, we propose a decision tree based approach to calculate the cost of operating an IDS in a mobile ad hoc network. Mathematically and programmatically we deduce the minimum operating point of operation of an IDS and generate the receiver operating characteristic curve of the IDS. To further ascertain this, we use available network packet capture data and calculate the minimum operating cost of an IDS. The main motive behind this paper is to show that the cost of operating an IDS in a MANET can be minimized and hence the effectiveness and performance of the IDS can be maximized.
rusticana is the
commercial source of the enzyme Horseradish Peroxidase (HRP). Calcium ions play
an important role in the functional conformation of HRP. The present study
assesses the effect of three calcium salts viz., calcium chloride (CaCl2),
calcium nitrate [Ca(NO3)2] and calcium sulphate (CaSO4)
on the guaiacol activity of crude peroxidase extracted from the shoots and
roots of in vitro grown plantlets of A. rusticana and their growth medium.
The highest activity was observed in the shoot extracts of 25 mM CaCl2 treated plantlets (1.92 U/mL) and the root extracts of 25 mM Ca(NO3)2 supplemented plantlets (2.84 U/mL). The crude peroxidase activity of the medium
containing 25 mM CaCl2 supplement was
highest (0.13 U/mL). The capacity of the shoot and root extracts to decolourise
a 10 ppm solution of methyl orange
over 48 hours, was also tested. The decolourisation capacity was highest in the
shoot extracts from CaCl2 treated plantlets (49.32%) and root
extracts from Ca(NO3)2 treated plantlets
In this paper, I examine the effects of gender and race/ethnicity on American workers’ workplace identities. Literature on gender, work, and occupation suggests that gender and race are significant predictors of workers’ workplace identities. Literature also posits that self-perceived competency and reflected appraisals from others in workplaces also contribute considerably to workers’ workplace identities. However, there exists hardly any empirical study that explores the impacts of gender, race, workers’ self-perceived competency, and their reflected appraisals altogether on their workplace identities. That is what I accomplished in this study. Deriving the data from the National Study of Changing Workforce (NSCW: 2008) I ask: 1) Do women and men workers in America differ in their perceptions of workplace identities; 2) Do non-white and white workers in America differ in their perceptions of workplace identities; and 3) Do gender and race of the workers impact their workplace identities when self-perceived competency and reflected appraisals enter the equation? Analyses are based on quantitative methods. Results show that workers’ self-perceived competency and their reflected appraisals are more significant predictors of their workplace identities than gender or race.
