    In the 16th century, a group of Franciscan monks seized a chance to communicate the inevitability of death and erected a chapel in which one could assume the proper mindset to contemplate one's own demise. It was with this goal in mind that the Capela dos Ossos (Chapel of Bones) was built in Evora, Portugal, displaying thousands of skulls and bones, as well as two full skeletal corpses, cemented into its walls. Over the years, the chapel has become a popular tourist attraction, serving as a macabre monument to transitory life. View full abstract»

  • A foundation for enhancing your IEEE involvement

    As early as my sophomore year in college, I began receiving calls from my university alumni association soliciting donations. Earning my college degree seemed to make me an even bigger target for charitable solicitations from various organizations. There are so many worthy organizations, and it's great to help our universities prepare for future generations of graduates, but students and young professionals may not have philanthropic resources available, especially as we tackle student loans and save for our futures. We all may be a little guilty of avoiding or ignoring information coming from nonprofit organizations, thinking they are just trying to get something out of our paltry bank accounts, although they may have an important message to share.

  • Mitigation of asteroid impact threats

    Although large asteroids and comets have impacted the Earth in the past, we do not want large ones to impact us in the future. Can we prevent this from happening? A considerable amount of work continues to be done in detecting asteroids that may pass near the Earth, but solving the engineering problem of how to actually conduct a mission to deflect an asteroid is still in its infancy. Of the many ways considered to deflect an asteroid, the methods currently in favor fall into three categories: (1) kinetic impactor, (2) nuclear standoff explosion, and (3) gravitational tractor. Other techniques such as landing machinery on the asteroid and shooting off material (mass driver), or parking a giant minor near the asteroid and focusing the sunlight on it to ablate material, are not strongly in favor at this time.

  • Catching the wave: real-time tsunami warning systems

    People all over the world witnessed the fear of a tsunami following the Indian Ocean earthquake that struck on 26 December 2004. Many people may have learned the word and the phenomenon of a tsunami for the first time from this catastrophe. The word "tsunami" (meaning "harbor wave") comes from the Japanese language, and Japan has suffered considerable damage from such natural disasters. Therefore, Japan's research regarding tsunami is active. This research consists of various approaches including experiments, numerical computations, and social sciences, among others. This article introduces the research of a numerical computation, particularly the research of the real-time warning system of a tsunami. View full abstract»

  • Integrated space technology monitoring of mosquitoes and malaria epidemics

    Transmitted by the Anopheles mosquito, malaria is the world's most deadly vector borne disease. Mortality, currently estimated at over 1 million people per year, is rising. Epidemics account for up to 25% of the disease burden, and these too are increasing. This global resurgence in both incidence of epidemics and their mortality has been attributed to several factors: drug-resistant parasites, insecticide-resistant vectors, population shifts, war-damaged infrastructures, altered meteorological conditions, and drastic ecological transformation. In recent years satellite technology has demonstrated a key value to support a great variety of applications for the development of our society and economy. The three main space-based domains providing relevant infrastructure and facilities are satellite systems for Earth observation, telecommunication, and geopositioning/navigation. Such technologies are complementary to each other, and their synergetic integration can achieve the required product and service characteristics satisfying the needs of the different users ranging from weather forecasting and natural resource monitoring to disaster management and law enforcement activities. Health-related applications are an emerging domain that has to respond and address complex and global challenges. View full abstract»

  • Cascading failures in power grids

    Power grids are complex dynamical systems, and because of this complexity it is unlikely that we will completely eliminate blackouts. However, there are things that can be done to reduce the average size and cost of these blackouts. In this article we described two strategies that hold substantial promise for reducing the size and cost of blackouts. Both "reciprocal altruism" and "survivability" respect the necessarily decentralized nature of power grids. Both strategies can be implemented within the context of the existing physical infrastructure of the power grids,which is important because dramatic changes to the physical infrastructure are prohibitively expensive. However, additional engineering and innovation will be needed to bring strategies such as these to implementation and to create power grids with smaller, less costly blackouts. View full abstract»

    The article gives an overview on the issue of bird-aircraft strikes (birdstrikes) disasters on airfields. The author gives the analysis on the impact force exerted on the plane in a birdstrike. The article sites measures that was undertaken by airfields in preventing this natural disaster. It also presents the potential of radar technology to manage this birdstrike risk in airports.

  • Dating volcanic eruptions with tree-ring chemistry

    Dendrochemical analyses of absolutely dated, overlapping sequences of tree rings allow identification of temporally conscribed, volcanically influenced periods of environmental change. Dendrochemistry, or the study of tree-ring elemental composition, is a promising new technique for reconstructing climate/environmental history at annual resolution. In particular, dendrochemistry may be useful for identifying periods of climatically and/or environmentally effective volcanic activity. Airborne pollution from major volcanic eruptions in the form of increased environmental acidity from sulfur dioxide can cause changes in availability and concentration of certain elements and can increase the availability of those elements in the soil, resulting in increased uptake by trees from the substrate or direct from the atmosphere. In particular, spikes, dips, or major changes in trace element concentration may be an indication of changes in soil or atmospheric chemistry (e.g., Padilla and Anderson 2002). Although there are other records of past volcanism (especially from ice-cores - e.g. Vinther et al. 2005), tree-ring based work (e.g. Salzer and Hughes 2007) offers several important advantages: first, tree-ring series are available with wide spatial coverage from most of the globe, and second, they are datable with annual and even subannual resolution on a fixed (absolute) calendar timescale (whereas even the best ice-core work has errors of several years or more beyond the last few hundred years).
