The role of space in the security and defence policy of Turkey. A change in outlook: Security in space versus security from space

Space and security domains are strongly related with each other. Nowadays, space is an indispensable part of security and defence policy, and it is increasingly becoming a critical infrastructure for strategic Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) systems. However, space is vulnerable itself to the new space threats. This study reviews the current and near future space role in Turkey's security and defence policy and aims to address the threats against space based capabilities. To provide security from space, space based systems shall themselves need to be secure in space to warrant the security. The concept of security from space starts with space security, in other words the security in space. This paper also highlights the emerging technological opportunities for these space threats to be secure in space in order to provide the security from space. According to the relevant taxonomy, a categorized opportunity proposal for more robust and resilient space/satellite projects' architecture is proposed for Turkey

Market distortions and corporate governance

This paper studies corporate governance when a firm faces imperfect competition. We derive firms' decisions from utility maximization by individuals. This reduces the usual monopoly distortion. We find that corporate governance can effect the equilibrium in the product (or input) markets. This enables us to endogenize the objective function of the firm. If the firm cannot commit not to change its constitution, we find a Coaselike result where all market power is lost in the limit. We present a more abstract model of governance in the presence of market distortions and discuss its implications for the governance of universities

Search for Gravitational Waves from Intermediate Mass Binary Black Holes

We present the results of a weakly modeled burst search for gravitational waves from mergers of non-spinning intermediate mass black holes (IMBH) in the total mass range 100--450 solar masses and with the component mass ratios between 1:1 and 4:1. The search was conducted on data collected by the LIGO and Virgo detectors between November of 2005 and October of 2007. No plausible signals were observed by the search which constrains the astrophysical rates of the IMBH mergers as a function of the component masses. In the most efficiently detected bin centered on 88+88 solar masses, for non-spinning sources, the rate density upper limit is 0.13 per Mpc^3 per Myr at the 90% confidence level.Comment: 13 pages, 4 figures: data for plots and archived public version at https://dcc.ligo.org/cgi-bin/DocDB/ShowDocument?docid=62326, see also the public announcement at http://www.ligo.org/science/Publication-S5IMBH

Manejo del calor : Gestión estratégica de diseño para disipadores eco térmicos

La propuesta de la cátedra en su quinto año se centra en el desarrollo de los valores de la profesión desde una gestión integral de diseño. Se estimula la capacidad crítica, situada territorialmente y en relación con actores reales del medio que propician posicionamientos para el aprendizaje y la práctica en torno a la detección de nuevos lugares de desarrollo tecno-productivo. Su fin es tender puentes entre la práctica proyectual del taller en la universidad con la práctica reflexiva situada en contextos reales.Facultad de Arte
