In the last decade or so, human geographers have paid greater attention to the significance of discourses. We acknowledge the importance of discursive constructions and metaphorical representations of economic space, and extend the argument by examining the practices that may follow from such discourses. With use of empirical data from a firm-level survey and interviews with representatives of ...

Space-time coding and multiple-input, multipleoutput wireless system promise to deliver higher data rates with higher reliability than traditional systems, with no increase on transmit power or bandwidth. In this expository paper, we present multiple-antenna systems and their ability to increase the number of dimensions that may be transmitted per channel use. We present two space-time codes, o...

I examine the potential impact of 36 innovation, technology and market characteristics that may determine, at an early stage assessment, the probability that R&D projects will later reach the market. Analysis is based on data from 561 R&D projects developed outside of established organizations. Administrative records contained subjective evaluations of 36 project characteristics conducted at th...

Positive realness and bounded realness are two important issues in system theory. Some related applications about these notions include analysis and synthesis of passive networks, optimal designs in control and estimation, stability investigations in lineadnonlinear closed-loops; etc.. In this paper, we propose the equations of constant matrices, which are stabilizable and detectable realizatio...

The development of minimally invasive techniques allowed access to the necrotic cavity through transperitoneal, retroperitoneal, transmural and transpapillary routes. The choice of access to walled-off pancreatic necrosis (WOPN) should depend not only on the spread of necrosis, but also on the experience of the clinical center. Herein we describe treatment of a patient with multilocular symptom...

In the previous chapter it became evident that the Zimbabwean space economy is very unequal in terms of socio-economic development and that there are several development problems. Over the years the Zimbabwean government, like other governments in countries with severe spatial inequalities in development, has adopted various policies and strategies to obtain a more equal spatial distribution of...
