In this paper, we analyze one of the main drawbacks of droop control-based DC microgrid systems, and propose a novel control method to overcome this problem. Typically, DC microgrid systems use droop control techniques to enable communication independency and expandability. However, as these advantages are based on bus quality and regulation abandonment, droop-based schemes have limitations in ...

This research aims to identify the security threats in on-demand routing protocol, AODV for Ad-hoc network. In this context we have extended the AODV protocol with trust and recommendation to secure the network. In AODV, establishment of routing path depends on the faster route request and route reply packets. Rushing attacker exploits such faster traversal activities to attack the network. Rus...

"This paper uses a perfect foresight life cycle simulation model to examine the dynamic economic effects of baby 'booms' and baby 'busts' as well as the interaction of such demographic changes with social security policy. Demographic change can have sizeable short and long-run effects on saving rates and factors returns." The geographic focus is on the United States. "The model predicts long...

As we increase our dependency upon networked communication, the incentive to compromise and degrade network performance increases for those who wish to disrupt the flow of information. Attacks that lead to such compromise and degradation can come in a variety of forms, including distributed denial of service (DDoS) attacks, cutting wires, jamming transmissions, and monitoring/eavesdropping. Use...

The growing internationalisation of the world economy in recent decades has placed firms under strong competitive pressures, but has also handed them new opportunities to improve their productivity by exploiting, for example, the cost advantages and technological progress available to those which import intermediate goods and services for use in their production. Despite the strong development ...

The coming into force in 2007 of Law 39/2006 about promotion of personal autonomy and care for people in a situation of dependency has created the right of everyone in these circumstances to be served by public services. This law involves an expansion and complement of the protective action of the State and Social Security System. To date these people have been treated by state, regional and lo...

Social Insurance Networks Based on administrative panel data from Norway, we examine how social insurance dependency spreads within neighborhoods, families, ethnic minorities, and among former schoolmates. We use a fixed effects methodology that accounts for endogenous group formation, contextual interactions, and time-constant as well as time-varying confounders. We report evidence that social...

The looming Social Security financing imbalance is one of the most pressing economic issues in the United States today. The resolution will have a substantial impact on the economic and social well being of current and future generations. To date, academic research has focused mainly on whether the United States should undertake structural reform, rather than whether it is likely. I present a d...

objective: this project aimed to study early maladaptive schemas in adults with parents afflicted with schizophrenia. methods: in a causal-comparative study, a sample of 39 adults with one schizophrenic parent as the experiment group and 40 students without schizophrenic parents as the control group were selected. both groups completed early maladaptive schema questionnaire. descriptive statist...
