Power transmission grid infrastructures deliver electricity across large distance and are vital to the functioning of modern society. Increasingly these setups embody highly-coupled cyber-physical systems where advanced telecommunications networks are used to send status and control information to operate power transmission grid components, i.e., "smart grids". However, due to the high inter-dependency between the communication and power grid network layers, failure events can lead to further loss of control of key grid components, i.e., even if they are undamaged. In turn, such dependencies can exacerbate cascading failures and lead to larger electricity blackouts, particularly under disaster conditions. As a result, a range of studies have looked at modelling failures in interdependent smart grids. However most of these designs have not considered the use of proactive network-level survivability schemes. Indeed, these strategies can help maintain vital control connectivity during failures and potentially lead to reduced outages. Hence this thesis addresses this critical area and applies connection protection methodologies to reduce communication/control disruption in transmission grids. The performance of these schemes is then analyzed using detailed simulation for a sample IEEE transmission grid. Overall findings show a good reduction in the number of overloaded transmission lines when applying network-level recovery schemes.

Recovery from disaster is a challenging period for any community. Long-term recovery is important, especially in relation to the built heritage, but it is among the least explored phases of disaster. Identifying past problems is needed to reduce future recovery complications. This study investigates the long-term recovery of public and Non-Government Organizations (NGO) owned historic buildings after an earthquake in the light of chosen sustainability variables. It examines San Francisco after the 1989 Loma Prieta earthquake as a case study and analyzes time needs, community participation, and maintenance of historic character, to identify whether historic buildings faced special issues and the variables involved. The study uses different methods. It statistically compares data for a sample of public and NGO owned buildings in San Francisco and then analyzes the dynamics of recovery for three buildings that faced delays. The study has found that historic buildings faced delays in recovery but such delays were sometimes the results of major rehabilitation projects, thus having long-term benefits. There are many variables in the recovery process that delay historic buildings and can be addressed to reduce future delays, which are mostly results of the context, process, and players. Time needs for the recovery of buildings are affected by their function, damage level, and status. Also, the sustainability of the process needs to be addressed, mainly in terms of the way historic buildings are valued, and the degree to which such valuation allows them to be part of the heritage of the community at large.

This is a study of how two small neighbourhoods, Mano and Mikura, recovered from the 1995 Kobe (Japan) earthquake, with a particular focus on the relationship between community vulnerability and capacity. Few studies have examined these interactions, even though vulnerability reduction is recognized to be a vital component of community recovery. Drawing from literature on disaster recovery, community development, vulnerability analysis, community capacity building and the Kobe earthquake, a community vulnerability and capacity model is elaborated from Blaikie et al.’s Pressure and Release Model (1994) to analyze the interactions. The Mano and Mikura cases are analyzed by applying this model and relating outcomes to the community’s improved safety and quality of community lives. Based on the experience of Mano, appropriate long-term community development practices as well as community capacity building efforts in the past can contribute to the reduction of overall community vulnerability in the post-disaster period, while it is recovering. On the other hand, the Mikura case suggests that even though the community experiences high physical and social vulnerability in the pre-disaster period, if the community is able to foster certain conditions, including active CBOs, adequate availability and accessibility to resources, and a collaborative working relationship with governments, the community can make progress on recovery. Although both Mano and Mikura communities achieved vulnerability reduction as well as capacity building, the long-term sustainability of the two communities remains uncertain, as issues and challenges, such as residual and newly emerging physical vulnerability, negative or slow population growth and aging, remained to create vulnerability to future disasters. The case studies reveal the interactions of community vulnerability and capacity to be highly complex and contingent on many contextual considerations.

The networking field has become a core component for any company. All of the businesses rely on the networking industry, due its vastness and significance. Every day companies are planning and thinking to develop better strategies that can offer efficient and reliable communication solutions between their employees and customers for maximum revenue. The planning of a company’s network requires a lot of resources and aspects to study, and to evaluate them carefully to build a comprehensive secure and reliable platform. It is the job of a network administrator to take care of the company’s network infrastructure and upgrade or update the required components and applications from time-to-time that can follow new standards. This thesis is a practical work aimed to evaluate a company network infrastructure in its real environment. The purpose of this thesis is to evaluate different aspects of the network infrastructure used such as VPN, WLAN, firewall and physical security and give recommendations to make their performance better and to offer more advanced strategies. This study will also provide an inclusive observation of the company’s needs and their network infrastructure, and will provide a concept how to evaluate and fix small mistakes, the kind of problems that can occur in an evolving company network. Lastly, this research will make recommendations and suggest a possible implementation on the studied network infrastructure.

Anecdotal evidence in disaster studies suggests that multifamily housing takes longer to recover than single family homes, but almost no studies have provided quantitative evidence to clarify this “multifamily home lag” phenomenon. This research examines the recovery of single family, duplex, and apartment complex housing in south Miami-Dade County, Florida, after 1992 Hurricane Andrew to determine if there is indeed a "multifamily home lag." This research also provides a better understanding of the factors influencing the recovery trajectories of these three housing types. The findings of this research indicate that duplexes and apartment buildings have slower recovery trajectories than single family dwellings. In addition, rental housing, housing that sustained higher levels of damage, and single family dwellings and duplexes located in predominately non-Hispanic Black neighborhoods show significantly slower recovery trajectories. The analyses specific to apartment buildings also finds that apartment buildings with fewer than 10 units have significantly slower recovery trend than apartment buildings with more than 50 units.

Abstract The motive of thesis is trying to find out the role of information system security via the researching company ¡V CTS Corporation¡¦s disaster recovery plan and present a model to discuss with that. While through the researching procedure, we found out that most of information security systems obey the BS 7799-2 and ISO 17799 even the CNS 17799 in the world. Through the help of investigation of the questionnaire, all evidence just show out that how to construct and recognize the information security system is the issue and trend for enterprise to do after the ISO 9000 and QS 9000. Since 1978, the case study company, CTS Corporation has had fire and evacuation procedures, which were informally supported by various committees. An emergency plan, which was issued March 24, 1980, incorporated the functions of these committees and provided more formalized procedures for responding to emergencies. The emergency plan was later reissued as know of ¡§CTS Corporation Disaster Recovery Plan¡¨ as one of policy to be followed. In thesis, widely discuss the risk and evaluation of information security and show up some of major case of the information security for domestic and international by sequence of the date. Present some of overview from industry¡Bgovernment and academic how to face such of information security around the enterprises. Final conduct of 10 control sets, 36 control subjects and 127 control items with 8 abstracts of ISO 17799 introduction from BS 7799-1 and BS 779902 with comparison of ISO 17799 totally. Compare and distinguish the variance from CTS Corporation and those of international standard for the information security system, we deploy 4 steps of development the information security system as of: Information Security Policy; Documentation and Implementation; Risks Management and Information Security Management Security (ISMS). Provide evidence of questionnaires of the case study company. Summary three of dimensions for five(5) issues of ¡§Environment & Infrastructure¡¨, seven(7) issues of ¡§Disaster Recovering Planning¡¨ and six(6) issues of ¡§Business Contingency Planning¡¨ to conduce a Disaster Recovery Planning¡¦s Deployment Model for seven steps of four scenario as a conclusion.
