Smart materials application on high performance sailing yachts for energy harvesting

Piezoelectric patches are bounded on a keel bulb in order to harvest vibration energy by converting electrical output. Unsteady computational fluid dynamics method is also used to find the structural boundary condition such as the hydrodynamic pressure fluctuation. Finite element analysis (FEM) is used to find structural and electrical responses

Numerical study of asymmetric keel hydrodynamic performance through advanced CFD

The hydrodynamics of an asymmetric IACC yacht keel at angle of yaw are presented using simulations performed by advanced computational fluid dynamics using state-of-the-art software. The aim of the paper is to continue working on the improvement of numerical viscous flow predictions for high-performance yachts using Large Eddy Simulation and Detached Eddy Simulation on unstructured grids. Quantitative comparisons of global forces acting on the keel and wake survey are carried out. Qualitative comparisons include flow visualisation, unsteady and separated flow and other features. Star-CCM+ and the trimmed cell method give better forces and wake prediction compared to the unstructured mesh of ANSYS Fluent. Both solvers give good flow visualisation near and far field of the keel

Frisch Demand Functions and Intertemporal Behaviour in Consumption: The Turkish Case

This paper examines the intertemporal behaviour in consumption for Turkey which has been experiencing high and chronic inflation since the late 1970s. The Frisch demand system is used to estimate three separate but inextricably intertemporal elasticities: intertemporal price elasticities of demand, commodity-specific intertemporal elasticities, and the intertemporal substitution elasticity of consumption. Our main result is that the Turkish households are reluctant to move their expenditures on non-durable goods from the current period to the next period, regardless of how high nominal interest rates are. This interesting result shows that the consumption behaviour in Turkey has been mainly shaped by uncertainty created by inflationary process and the tendency towards hedging against inflation.

Regulator indecomposable cycles on a product of elliptic curves

We provide a novel proof of the existence of regulator indecomposables in the cycle group CH2(X; 1), where X is a sufficiently general product of two elliptic curves. In particular, the nature of our proof provides an illustration of Beilinson rigidity. © Canadian Mathematical Society 2011

The Baby Boom, Baby Busts, and Grandmothers

Studies in family economics and anthropology suggest that grandmothers are a highly valuable source of childcare assistance. As such, availability of grandmothers affects the cost of having children, and hence fertility decisions of young parents. In this paper, we develop a simple model to assess the fertility implications of the fluctuations in both output (as argued by demographers) and grandmother-availability induced child-care costs over the period 1920-1970. Model does a good job of mimicking the bust-boom-bust pattern during this period. When the child-care cost channel is shut down, the model’s performance weakens significantly; in particular, it fails to capture the bust in the 1960’s altogether.fertility, baby boom, baby bust, female labor-force participation, grandmother availability

Stabilization of the Turkish Economy in the Early 2000s and the Urgent Action Plan

The first major crisis that the Justice and Development Party, which came to power in 2002, had to deal with was the deep social divisions caused by the 1990s, and especially the Ecevit era, and the near-bankruptcy of the Turkish economy. Without wishing to be exhaustive, it is worth highlighting some of the factors and events from this period in order to make visible how complex the crisis was that the AKP had to deal with while stabilizing Turkey after their first election victory. One of the reasons for the constant crisis of the 1990s was that the political scene was extremely polarized, many parties with relatively little influence were present in the National Assembly, and they were unable to secure a stable government majority. As a result, coalition governments were formed in which parties with very different ideologies participated. After a while, the army also intervened in the ongoing battles of the parties. In 1997, during the so-called the postmodern coup, the Turkish armed forces published an e-memorandum on the Internet. With this document, the government of the radical right-wing Necmettin Erbakan was finally overthrown. Between 1997 and 2002, there was a deeper political crisis compared to the previous years, it marked the repulsion of Turkish political life. The political crisis was further exacerbated by one of the greatest natural disasters of the republic’s era, the 1999 earthquake, which claimed tens of thousands of lives in the eastern basin of the Marmara Sea. The disaster, which had just ruined the developing hinterland of the country’s industry, slowed the businesses and the recovery exceeded the capabilities of the Turkish economy. After 1999, nearly one million small and medium-sized businesses went bankrupt. Not only companies, but also families were in an extremely difficult position with unemployment in the skies and inflation galloping. In this economic crisis, the pre-AKP Turkish governments resorted to the instrument of neoliberal economic policy. Kemal Dervis, an internationally known and recognized economist, was asked to create the economic recovery program. However, the extreme austerity measures provoked even more serious social tensions, which brought the long 1990s to the point where the last coalition government also failed. The present article aims at describing the nature of the economic crisis of 2001, and the forms of recovery used by Kemal Dervis and the subsequent AKP governments. Globally speaking, the economic crisis management was successful, so this paper –using both English and Turkish language sources- tries to clarify how the neo-liberals of the late Ecevit era and the liberals of the early AKP period contributed to this achievement

Division, Persecution and Rearrangement - The AKP’s Controversial Relationship with Turkish Civil Society

Throughout history, and especially in the Ottoman Empire, Turkish culture has attached great importance to foundations. In the past, mosques, schools, public baths, free kitchens, and hospitals alike, all operated in the form of foundations. After the proclamation of the republic in 1923, much of this structure was abolished by the state founder Mustafa Kemal Ataturk because he believed that they were tied to the Muslim clergy by a thousand threads. In the initial period of the republic, Turkish civil society was slowly reorganized following Western examples. It lived its second heyday as a result of the introduction of the new constitution in 1982 and Turgut Ozal’s liberal economic policy, and his media market liberalization after 1983. After the Justice and Development Party came to power in 2002, the civil society in Turkey was significantly rearranged. Recep Tayyip Erdogan’s party favored some with a system of opportunities, and sued those who put the government in a politically awkward position. Building on some of the scandalous cases of the second half of 2010s, this article seeks to explain the current situation of Turkish civil society and the conflicts that characterize it. The article highlights the campaign against Amnesty International and the Open Society Foundation, which by November 2021 was only partially over. In the case of current events, in the absence of scientific sources, the writings of renowned Turkish journalists at world-famous news portals were used as a basis. However, in order to substantiate the theory, an abundant literature in Turkish and English was also used
