Long Time

Computer viruses have been studied for a long time both by the research and by the application communities. As computer networks and the Internet became more popular from the late 1980s on, viruses quickly evolved to be able to spread through the Internet by various means such as file downloading, email, exploiting security holes in software, etc. Epidemiological models have traditionally been used to understand and predict the outcome of virus outbreaks in human or animal populations. However, the same models were recently applied to the analysis of computer virus epidemics. In this work we present various computer virus spread models combined with applications to e-health systems.

As computer networks and the internet became more popular from the late 1980s on, viruses quickly evolved to be able to spread through the internet by various means such as file downloading, email, exploiting security holes in software, etc. In general, epidemic models assume that individuals go through a series of states at a certain constant set of rates. Different epidemic models have been proposed based on the characteristics of the systems and the topology of the network. In this chapter, an analysis of various epidemic models will be analyzed under differential mathematical systems.

Computer Viruses

With the rapid popularization of the Internet, computers can enter or leave the Internet increasingly frequently. In fact, no antivirus software can detect and remove all sorts of computer viruses. This implies that viruses would persist on the Internet. To better understand the spread of computer viruses in these situations, a new propagation model is established and analyzed. The unique equilibrium of the model is globally asymptotically stable, in accordance with the reality. A parameter analysis of the equilibrium is also conducted.

Computer virus spread model concerning impulsive control strategy is proposed and analyzed. We prove that there exists a globally attractive infection-free periodic solution when the vaccination rate is larger thanθ0. Moreover, we show that the system is uniformly persistent if the vaccination rate is less thanθ1. Some numerical simulations are finally given to illustrate the main results.

Technology nowadays are vastly growing and by that the number of virus are also increasing each day. There were 60,000 known viruses, Trojans, worms, and variations and today there are well over 100,000 known computer viruses. In addition, studies and researches show that a computer connected to the Internet may experience an attack every 39 seconds. The purpose of this research is promote the importance of computer viruses using computer game platform. In Malaysia, there are still less effort of using new media on preventing computer virus and Malaysian society are still lacking of knowledge and awareness on how to avoid their computer from getting occurrence or harmed by virus. Furthermore, this research will also assess the efficiency of the 3D game prototype among selected respondents.

In the era of technological advances, tourists will first seek information about the tourist object to be addressed, even tourists often don't have a destination, so they have to search one by one via the internet. In determining travel plans, it is often to see one by one the review of tourist attractions and conclude the results will take a long time, while tourists need actual and fast information to determine the travel plans. In this study, the authors take a new approach, namely by creating a mobile-based travel planner system that compiles travel plans automatically by considering contextual information related to tourist location points, whether of tourist locations during travel days, travel opening and closing hours, so that it will increase travel efficiency without having to do the research manually which takes a long time. The system can also provide travel recommendations based on visitor comments sentiment on Google Places and is equipped with a trip route that will be generated automatically. This research is useful for helping tourists plan their trip actually because of the consideration of contextual information so that it will make it easier and save tourists time.

Home industry production results are only traditionally managed as promoted by word of mouth, and sometimes rely solely on the number of visitors to the sales place of the product, so the product takes a long time to increase sales volume. Now with capitalize a set of computers or smartphones that have been equipped with the Internet network can be used as a tool or media to publish all activities / promotional activities undertaken by the domestic business actors. In this activity, business activists will be given material about what the website, especially weblog and its benefits, how to make it, and how to use and manage it properly to support and improve the ability in promoting the product. This is not without reason, because almost all citizens who already have a household business is less understand the use of the internet let alone use the Internet media as one of the media to promote household products that they produce. The main target in the implementation of community service activities is to improve the ability of the community in the utilization of the Internet as a powerful medium as a partner of the government in moving the economic factors.

Exhaustive Study

My motivation in editing this book has been to present as compelling and credible a story as possible. Although I am personally convinced of the soundness of our argument, that food web architecture plays a key role in the cyclic dynamics of many animal populations, I am not sure that others will be so convinced. In this final chapter, therefore, I exercise my prerogative as editor to have the last word, a final attempt to convince the skeptics and to answer the critics.Perhaps the most compelling case comes from the Mikael Münster-Swendsen monumental study of a needleminer infesting Danish spruce forests (chapter 2). Mikael is the only person I know of who has, almost single-handedly, and with considerable precision, measured all the variables suspected of affecting the dynamics of a particular population over an extended period of time (19 years) and in several different localities (seven isolated spruce stands). Others have longer time series from more places, but none has been so complete in terms of the number of variables measured. This exhaustive study enabled him to build a model of the complete needleminer life system, and use this model to home in on the factors responsible for the cyclical dynamics. However, the story would not have been complete without multivariate time series analysis, which led to the discovery of parasitoids as the cause of the key feedback process, density-related reduction in fecundity. The lesson from Münster-Swendsen's work is clear: If we want to understand population dynamics, we need long time series for all the variables likely to affect the dynamics of the subject population(s). In other words, we need to consistently monitor ecological systems over long periods of time and in many different locations. If there is a weakness in his study, it is the absence of the final definitive experiment. Such an experiment would be relatively easy and cheap to do (relative to those described in other chapters), because isolated spruce stands are common in Denmark and parasitoids emerge from the soil a week or two after the needleminer. Thus, parasitoids could easily be excluded by spraying the ground with an insecticide after needleminer emergence.

Development And Management

User involvement in cancer services operates at two levels: providing information and involving patients and carers in decision-making about their own care, and involving patients and carers in decisions about the development and management of cancer services. Information can be provided to patients verbally, in written material, and through patient-held records, and they can also have access to information via the Internet. Most people want to take an active role in making decisions about their care and treatment; however, this varies from person to person. Being fully informed is important to more people than being fully involved in the decision-making process itself. Issues of consent and competence are very important when involving patients, and nurses need to take account of these and also the condition of the patient, when involving them in the decision-making process. Involving cancer service users in evaluating and managing health care has the benefits of improving services and public understanding, and improving health. It can take the form of providing information and seeking feedback on services, consulting on developments to services, and participation in planning, managing, or evaluating services. These can be achieved through questionnaires and surveys, focus groups, membership of committees, or employing service users as consultants to services. For user involvement to be effective, it should be meaningful, the language should be inclusive, and minority perspectives should be represented.
