Systematic approach to natural gas usage for domestic heating in urban areas

Natural elements spatial configuration and content usage in urban park

Abstract Urban parks are important public multifunctional space used for a wide range of activities. The usage levels of parks depend on the spatial characteristics of the spaces, where its forms and occupancies are referred as the usage-spatial relationship. Natural elements spatial complexity and park usability is of interest in this study. A photo - questionnaire was conducted among 296 of p...

Understanding Road Usage Patterns in Urban Areas

In this paper, we combine the most complete record of daily mobility, based on large-scale mobile phone data, with detailed Geographic Information System (GIS) data, uncovering previously hidden patterns in urban road usage. We find that the major usage of each road segment can be traced to its own--surprisingly few--driver sources. Based on this finding we propose a network of road usage by de...

Dynamic Allocation of a Domestic Heating Task to Gas-Based and Heatpump-Based Heating Agents

In this paper a multi-agent model for a domestic heating task is introduced and analysed. The model includes two alternative heating agents (for gas-based heating and for heatpump-based heating), and a third allocation agent which determines the most economic allocation of the heating task to these heating agents over the days in a year. For allocation decisions it is analysed how the performan...

The Domestic Natural Gas Shortage in China

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
