This paper reviews the arguments and some of the evidence on the emergence of gated communities and contends that the concept of the partitioned city has a useful application both in the private sector and public sector housing. The focus of the paper will be the UK context, and developments that have been largely ignored to date. The paper utilises the concept of ‘club economics’ to consider t...

Measured by both the physically fortified character and socio-legal systems of service delivery and governance, the number of neighborhoods in Hong Kong that falls into the category of gated community is huge. Gating here is widely employed in various types of housing estates, from luxury developments for the affluent, to aged tenement houses that usually house the less advantaged group, and ev...

All cities known to social scientists and historians have neighborhoods. People living in urban settings universally organize important aspects of their lives on a spatial scale that is intermediate between the household and the city. Urban authorities also tend to organize administrative ac­ tivities such as tax collection and record keeping on a similar scale. The spatial relationship between...

In gated radiotherapy, the accuracy of treatment delivery is determined by the accuracy with which both the imaging and treatment beams are gated. Time delays are of four types: (1) beam on imaging time delay is the time between the target entering the gated region and the first gated image acquisition; (2) beam off imaging time delay is the time between the target exiting a gated region and th...

A method for summing together datasets from gated cardiac PET acquisitions is described. Optical flow techniques are used to accurately model non-rigid motion present during the cardiac cycle so that a one-to-one mapping is found between each voxel of two gated volumes. Using this mapping, image summing can take place, producing a composite dataset with improved statistics and reduced motion-in...

We consider a discrete-time gated vacation system. The available buffer space is divided into two subsequent queues separated by a gate and new customers arrive either before or after this gate. Whenever all customers after the gate are served, the server takes a vacation. After each vacation, the gate opens which causes all waiting customers to move to the buffer space after the gate. The mode...

In this preliminary chapter, we analyse the two dimen¬ sions we believe hold greatest relevance to the gated housing estate phenomenon in general and which contribute most to studying its social production. Firstly, we interpret the phenomenon as a specific socio-spatial form with a defined physical morphology and with specific social characteristics, causes and possible effects. Secondly, we s...

Contemporary studies of gated communities largely associate this phenomenon with global forces, emphasizing recent urban processes that operate across national borders. However, the Israeli experience demonstrates that multiple forces work simultaneously to produce various forms of enclosed residential communities that follow very different evolutionary routes. Older forms of gated spaces such ...

The power dissipated by the level-1 Instruction cache is often a considerable part of the total power dissipated by the entire microprocessor. In this thesis, we focuses on reducing the power consumption of the I-cache by using an in-cache instruction compression technique that uses gated wordlines to reduce the number of bitline swings. First, we develop a cache power consumption model to esti...
