Disaster communications - Essay Example Consequently, the soviets were quick to react and sent two fighters so that they can intercept the intruding plane. After dialogues between fighter pilots and soviet control, the fighters were able to locate the Korean plane quickly and attempted to contact the pilot of the passenger plane. However, after failing to get a feedback from the pilot, one of the fighters lost patience and fired a missile to the plane, making it to plummet into the Sea of Japan, leaving 269 people dead (Grier, 2013). This is a clear illustration of how poor communication can result to severe damages such as death and destruction of equipment. The incident claimed innocent lives due to poor communication. A single action that would have prevented this occurrence was swift responding. The pilot of the Korean plane would have responded to the soviet fighters because he was aware that he was flying on unauthorized space. In the event that he had communicated adequately, the fighters would have allowed the pilot to use the Russian space. Conclusively, implementation of proper communication is possible and prevents occurrence of similar incidents in

The original traces come forth in form of the U.S supported government that was in place in Iran in the 1950s after a coup that took place in 1953 (Dabashi, p 73)). Although at that point, the United States of America facilitated it based on the need for civilian purposes, yet with time the role and intentions towards building this stockpile grew suspiciously awkward. In the post 1979 Iranian scenario, Iran has had a mixed reaction towards the acquisition of nuclear arsenal. Considering the Islamic outlook of the government, the official policy maintained by the government stated that the actions and building of the nuclear arsenal is against the values and spirit of Islam, for it causes direct damage and destruction to humanity, it therefore was officially declared that Iran does not aim following the nuclear ambitions (Parsi, p. 144). However, time and again the indications have been such that Iran is pursuing the silent acquiring of the nuclear stock pile. This has been reported number of times in the intelligence reports that have been collected based on the evidences and other factors through the works of the intelligence agencies. The large number of nuclear power plants and some of them are underground and have not been declared publically, this fact castes aspersion over the Iran’s intentions and brings about suspicion with regard to its actual motives behind the overall nuclear conundrum created. In the presence of such large number of nuclear power plants, one of the most critical one controversial one that has raised eye brows is that of Bushehr 1 reactor which has been built in association with Russia(Cordesman and Seitz ¸p 219).

Conservatism and Neo-Ottomanism of the Turkish Political System Essay

Conservatism and Neo-Ottomanism of the Turkish Political System - Essay Example Additionally, in contrast to the modernization movements of many of the governments in the post Ottoman Turkey, the Conservative ideology that has been adopted by the Turkish political system during the past decade (2002-2013) is largely opposed to the westernization of Turkey. For example, the conservatism themes of the Turkish governments within the last decade (2002-2013) has been characterized by a new form of nationalism, marked by attempts to conserve Turkish national values â€Å"ulusalclk† as well and social values such asexuality, family values, gender relations and religious values in the face of the current rapid globalization and perceived Europeanization (Yavuz, 2009). This has been particularly evidenced by the de-westernization and re-traditionalization of the Turkish society that has been witnessed in the country since the Justice and Development Party lead by Recep Tayyip ErdoÄŸan came to power in 2002. In a recent interview with Financial Times Newspaper, T ayyip ErdoÄŸan described his party’s vision and ideology as seeking to establish a conservative democracy in Turkey which is attached to the traditions, customs and values of the contemporary Turkish society.Finally, despite the fact that the consecutive AKP led governments in Turkey since 2002 have always rejected any association with Islamism or political Islam as part of their ideology, the main ideology of the Turkish political system under the leadership of AKP has been primarily characterized by institutionalization of Turkey’s traditional and religious values

The Automobile in America (American History) Research Paper

The Automobile in America (American History) - Research Paper Example Cars had been invented many decades earlier, but its high cost limited access to the majority of Americans. The Ford Company in the 1920’s changed the industry forever. The company’s superior mass production techniques allowed Ford to lower the cost of producing an automobile dramatically. The Ford Model T was the car model that became a mainstream in the 1920’s when the price of the auto was reduced to $310, nearly $500 cheaper than a decade earlier (Kenney, 2001). The company had the best selling product in America which was a critical success factor that gave Ford a competitive advantage. The Ford Company valued the effort of its workers. The company created thousands of good paying jobs which helped the American economy. By the end of the 1920’s Ford had manufactured and distributed 15 million Ford T vehicles across America (Virgina). The proliferation of the automobile accelerated the speed of growth of the American economy due to the fact that the ab ility to commute freely increased commercial activity and the amount of work opportunities for

Good Parent Essay Example for Free

Good Parent Essay Being parents must have many variable quality or responsibility for their children. Parents play a major role in the life of a child that the children can learn what they live with their parent. Good parent is invaluable to our society as lack of good parenting in can have long-term effects on children and on society. Good parents are those who are self-sacrificing, teachable, curious, and diligent. Firstly, one quality of a good parent is one who is self-sacrificing. A good parent does all he or she can to meet the needs of his or her children. Notice this is the child’s needs, not wants. Good parent should content childrens material needs, namely a home, food, clothes, and so forth. This provision should help at least on the level of minimum childrens requirements or better depending on parents financial capabilities, though not infinitely better so that not to surfeit and consequently spoil the child. Secondly, many decisions parents make are guided by the end goal of meeting these needs; decisions such as, the way money is spent and even how much or how little personal time is taken for oneself. Self-sacrificing does not mean that a parent gives up his or her life for their children, but they do end up putting much of their life on hold in order to put the child’s needs first. Good parents should actively promote childs physical and mental development. This include disciple the child, habitual the child to physical exercises and studying, providing the child with as best education as possible, and edifying or advising the child on any problem he or she encounters during life. Thirdly, good parent needs to be teachable. This is not to say that as a parent, you have to heed all, or even most of the advice readily given to you, especially if this advice conflicts with your values and ethics. However, if there is no conflict, a good parent should be able to accept the advice and mull it over for possible use or implementation. Parents make mistakes, it is going to happen. Being willing to listen and learn can help to avoid some of these mistakes, and learning from any mistakes that are made will make you a better parent in the end. Finally, the most important and quite comprehensive quality of good parents is being responsible for their children. This responsibility of activities and roles a parent should perform through the whole life or at least until the child become mature enough to live independently. Most of these activities spending a lot of time with children, which is in many cases problematic as adults usually have a lot of things to do in their lives even with no parenting taken into account. But good parents should always procure opportunities to spend with their children as much time as possible. Also, good parents should protect their children. It may imply protection of childs health, that is they should try to prevent the child from getting ill and take care of the child if he or she however got ill. Parents should also protect their children from any dangers both internal and external. An example of an internal danger may be a possibility of getting hooked on cigarettes, alcohol, or drugs. An external danger may be any ill intention from any other people, like bullies at school. Good parent should always provide both moral and material support for his or her children. In conclusion, good parent should help the child to go through the life to the adulthood in order to make him or her feel comfortable in the family.

Reinforced Concrete Walls Engineering Overview

Reinforced Concrete Walls Engineering Overview Reinforced Concrete (RC) walls are often used as coupled systems in construction of multi-story buildings because of their advantages in comparison with individual walls such as higher lateral stiffness, lower bending moments on each individual wall, and higher energy dissipation because of the inelastic deformations of coupling beams (El Tawil et al., 2010). These elements have been extensively utilized in medium-rise and high-rise building structures within the past decades. Nowadays, RC coupled shear walls are popular lateral force resisting systems, especially in high-risk seismic zones (Farhidzadeh et al., 2013). The reason behind this trend is that RC coupled walls are significantly capable of controlling the inter story drift ratio, which has been frequently used as a performance indicator in design of structures (Carrillo and Alcocer, 2012). Similarly, these structural systems are quite efficient in reducing the associated implication of non-structural elements damage. The expected energy dissipation mechanism of a ductile RC wall system under lateral deformations is flexural yielding (i.e. plastic hinges) at the base of both the cantilever and coupled wall systems, and at both ends of each coupling beam in a coupled wall system (Boivin and Paultre, 2012). Series of design provisions are specified in the current codes to confine the inelastic response at the wall base. These are aimed at ensure enough strength against undesirable modes of failure like brittle shear failure(Ghorbanirenani et al., 2012). Many researchers have conducted both experimental and analytical investigations to identify the behavior of coupled walls, and to improve the performance of these systems. The C-shaped coupled wall system (i.e. core wall) is one of the simplest and is a popular arrangement used in practice. Despite their popularity, however, there have been relatively few studies on the seismic behavior of these RC structures (Beyer et al. 2008), necessitating research on the seismic performance of C-shaped cores. One of the most important characteristics of these nonplanar wall systems is their response when the structure is subjected to torsional efforts due to the eccentricity of lateral forces. This will be more significant when the structural system is asymmetric in plan regarding the lateral stiffness and strength distribution. Such a configuration in plan of a building is prone to have large torsional response during a severe earthquake. Reports and field observations after the past earthquake s showed severe structural damages because of torsional effects (Hart, 1975; Esteva, 1987). A recent investigation by Dizhur et al. (2011) reported significant structural damages, which was apparently caused by a torsionallysensitive response, after the Christchurch earthquake in 2011. Most of the researches carried out in the past focused on the behavior of planar RC walls, including various proposed approaches for predicting their nonlinear flexure-shear interaction behavior (Colotti, 1993; Elwood, 2002; Massone et al., 2006 and 2009; Mullapudi and Ayoub, 2009; Zhang and Xu, 2009; Jiang and Kurama, 2010; Beyer et al., 2011; Panagiotou and Restrepo, 2011; Fischinger et al., 2012). These approaches were mostly based on fiber-section elements such as multiple-vertical-line-elements (MVLE) proposed by Vulcano et al. (1988). Biaxial behavior of concrete material (e.g. modified compression field theory; Vecchio and Collins, 1986) were also considered in some of these approaches. On the contrary, experimental researches on the performance of non-planar (e.g. C-shaped) RC walls subjected to lateral loads are very limited. In one of the first attempts, Ile and Reynouard (2005) examined three full scale U-shaped RC walls under thecyclic lateral loading. The purpose of the study wasto study the behavior of U-shaped walls against uniaxial and biaxial bending and shear, and to compare the design provisions required by two versions of Eurocode 8. A shell model was also developed for simulation of non-planar RC walls. Beyer et al. (2008-a) investigated the bi-directional quasi-static cyclic response of ductile U-shaped RC walls by conducting experimental tests on two half-scale specimens with different thicknesses. The tests mainly focused on the flexural behavior of walls, considering different directions of loading (two orthogonal as well as diagonal). Results showed the diagonal direction as the most critical direction, in which the maximum moment resisted by the wall was less than the corresponding value calculated by the plastic hinge analysis. Moreover, the displacement capacity of the wall in diagonal direction was found to be smaller than the other two orthogonal directions. A simplified numerical model was also developed by Beyer et al. (2008-b), and a practical approach was proposed for implementation and analysis of of U-shaped walls. The numerical approach was based on wide-column analogy, and has been shown to produce reasonable estimation of the inelastic displacement response for slender walls. Constantin and Beyer (2012) used a 3D multilayered shell element model for U-shaped walls to capture their local as well as the global behavior under diagonal loading. The model was developed using the software VecTor4 developed at the University of Toronto (Wong and Vecchio, 2003), and was found to be accurate in terms of loading capacity of the wall, but not for its displacement ductility. Lowes et al. (2013) examined three 1/3 scale C-shaped wall specimens, representing a part of a coupled RC core system, under biaxial loading protocols. Results of cyclic tests showed that bidirectional loading significantly affected the response for displacement cycles in excess of the yield displacement. At these displacement levels, bidirectional loading resulted in a significant reduction in the stiffness of the wall in the direction parallel to the web of the wall (loading activating strongà ¢Ã¢â€š ¬Ã‚ axis bending). Recently, Lu and Panagiotou (2014) presented a three-dimensional (3D) cyclic model for non-planar RC walls, based on beam-truss analogy. The model was able to predict the effects of flexure-shear interaction, considering biaxial behavior of concrete material, and account for mesh-size effects. Although the proposed model has been revised several times and they validated the model for three reinforced concrete T-shaped, C-shaped, and I-shaped section wall specimens, the modeling approach was found to be complicated in terms of calibration of truss members and material properties (Kolozvari, 2013). The results were also sensitive for precisely tracking the displacement responses of walls in a wide-amplitude. In design of RC shear walls, the fundamental design equations are mainly based on the plane sections remain plane assumption, which is unable to capture the shear lag effects related to flexure and warping torsion. Such effects can be substantial in non-planar (C-, I- or T-shaped) wall configurations, and might affect the response of structural system in seismic excitations. A study Boivin and Paultre (2010) was shown that the seismic provisions proposed by NBCC 2005 and the CSA standard A23.3-04 (2014) for design of ductile RC shear walls buildings could considerably underestimate the shear demand, especially at the base of the shear wall system. This issue would be due to the fact that the amplification effects from the higher modes of vibration cannot be efficiently taken into account by the current capacity design methods. In seismic design of a multi-story ductile RC wall, this can produce design strength envelopes that largely underestimate the seismic force demand. Hence, more studies need to be conducted on the seismic performance of these structural systems and effectiveness of available retrofitting methods, both of which were investigated in the current study. A recent research (Pelletier, 2015) showed that the dynamic shear amplification factor newly introduced in CSA A23.3-14 (2014) allows a more realistic seismic shear force demand to be obtained for RC shear walls. This factor should be applied to prevent brittle shear failure and to account for the inelastic effects of higher modes. However, RC shear wall systems that are designed based on the CSA A23-04 need to be controlled for shear demands. Moreover, CSA A23.3-14 excludes the coupled and partially coupled walls from the clause specified for accounting for inelastic effects of higher modes. Furthermore, NBCC 2015 provides a higher mode factor Mv which is equal to 1.0 for coupled shear walls except in very occasional cases, Ta=2.0 seconds and S0.2/S5=65, in which the Mv is equal to 1.03. On th e contrary, it was found by Boivin and Paultre (2010) that the shear envelope calculated based on the capacity design method is significantly unconservative in either the cantilever or coupled wall directions. Therefore, more accurate evaluations for the future designs and retrofit options for existing building are essential.
