The demand for security by urban elites has driven the subtle transformation of their neighbourhoods – and wider city with a more closed fragmented public realm, ‘anti-disorder’ design strategies increasing control. This article explores signature elements securityscapes in affluent domains Mexico City London, two very different cities yet similarly fragmenting inhibiting modes design. Extensiv...

This paper proposes on-line optimal operation planning and control of cogeneration systems (CGS). CGS is usually connected to various facilities such as refrigerators, reservoirs, and cooling towers. In order to generate optimal operation planning for CGS, startup/shutdown status and/or input/output values of the facilities for each control interval should be determined. The facilities may have...

Pakistan is a gas rich but power poor country. It consumes approximately 1, 559 Billion cubic feet of natural gas annually. Gas is transported around the country in a system of pressurized transmission pipelines under a pressure range of 600-1000 psig exclusively operated by two state owned companies i.e. SNGPL (Sui Northern Gas Pipelines Limited) and SSGCL (Sui Southern Gas Company Limited). T...

Abstract Practical assessment of subgrade settlement induced by train operation requires developing suitable models capable describing permanent deformation characteristics filling under repeated dynamic loading. In this paper, load triaxial tests were performed on coarse-grained soil (CGS), and the axial strain CGS different confining pressures stress amplitudes was analysed. Permanent behavio...

The Beshar River is one aquatic ecosystem,which is affected by pollutants. This study was conducted to evaluate the effects of human activities on the water quality of the Beshar river. This river is approximately 190 km in length and situated at the geographical positions of 51° 20 ́ to 51° 48 ́ E and 30° 18 ́ to 30° 52 ́ N it is one of the most important aquatic ecosystems of Kohkiloye and Boyera...

The function of a metro station area is vital for city planners to consider when establishing a context-aware Transit-Oriented Development policy around the station area. However, the functions of metro station areas are hard to infer using the static land use distribution and other traditional survey datasets. In this paper, we propose a method to infer the functions occurring around the metro...

OBJECTIVE Leptomeningeal collaterals, which affects tissue fate, are still challenging to assess. Four-dimensional CT angiography (4D CTA) originated from CT perfusion (CTP) provides the possibility of non-invasive and time-resolved assessment of leptomeningeal collateral flow. We sought to develop a comprehensive rating system to integrate the speed and extent of collateral flow on 4D CTA, and...
