Urban regeneration and renewal is one of the urban development subjects that have undergone substantial changes in last decades in its approaches and also management process. Despite these global changes, policy making in this field of urban development have been delayed in Iran. In the last three decades, the spread of distressed urban areas in Tehran and their vulnerability against earthquake...

We consider ordinary renewal stochastic processes (generated by independent events) and indicate that their basic distribution and associated generating functions obey the statisticalmechanical structure of noninteracting systems. Based on this fact we look briefly into the less known case of correlated renewal events. When the density distribution ψn(t) for the occurrence of the n-th event at ...

The increasing importance of environmental concern, fuel savings and unavailability of power has led to the renewal of interest in renewable energies. This paper examines global research patterns to assess development prospects. The various new and advanced methods to harness solar energy and also the methods to increase the efficiency of the existing techniques are discussed.

In this paper, we propose a mathematical framework for the analysis of Bluetooth systems energy efficiency. The dynamic of the system is modelled by means of a finite state Markov chain (FSMC). Hence, we resort to the renewal reward theory to derive an estimation of the average throughput and energy efficiency achieved by the different packet formats, both for AWGN and Rician fading radio chann...

Background: Any irregularities in self-renewal/differentiation balance in endometriotic MSCs can change their fate and function, resulting in endometriosis development. This study aimed to evaluate the expression of OCT4 transcripts (OCT4A, OCT4B, and OCT4B1), SOX2, and NANOG in endometriotic MSCs to show their aberrant expression and to support self-renewal/differentiation imbalance in these c...

Wireless sensor networks are characterized by multihop wireless lossy links and resource constrained nodes. Energy efficiency is a major concern in such networks. In this paper, we study Geographic Routing with Environmental Energy Supply (GREES) and propose two protocols, GREES-L and GREES-M, which combine geographic routing and energy efficient routing techniques and take into account the rea...

In renewal processes, fuzziness and randomness often coexist intrinsically. Based on the random fuzzy theory, a delayed renewal process with random fuzzy interarrival times is proposed in this paper. Relations between the renewal number and interarrival times in such a process are investigated, and useful theorems such as the elementary renewal theorem, Blackwell renewal theorem and Smith key r...

During a time of budget challenges, the Washington, D.C. government has needed to increase appropriations to the public safety and justice title while reducing appropriations to other municipal services. The need to increase policing costs by $1 million to $469.7 million in fiscal year 2012 diverges from the city’s efforts to improve underserved neighborhoods through urban renewal. Although the...

2. Government has undertaken its own urban renewal projects for many years. The Hong Kong Housing Society (HS) started its Urban Improvement Scheme in 1974. In 1988, the Land Development Corporation (LDC) was established to speed up the process of urban renewal. The Housing Authority (HA) has also played an important role in urban renewal, in particular by redevelopment of its own estates and a...
