Achieving high performance for concurrent applications on modern multiprocessors remains challenging. Many programmers avoid locking to improve performance, while others replace locks with non-blocking synchronization to protect against deadlock, priority inversion, and convoying. In both cases, dynamic data structures that avoid locking require a memory reclamation scheme that reclaims element...

Abstract: To evaluate the damage of land affected by disturbances in the course of construction. In 2011 our government abolished the regulations of land reclamation implemented in 1988 and introduced new regulations for land reclamation. The single-appropriate suitability evaluation of the new regulation has two influences: first, it offers the land oblige an opportunity that could legally pur...

The typical problems caused by Mining Subsidence and mining pollution made by coaling, made the Mine Subsidence reclamation and retorting the integrated mining environment necessary. Then, we create effective management measures of “full investigation, scientific planning, focused, sound institutions, the establishment of the system” and create the advanced technology of “mud pump reclamation, ...

Memory management is a critical component in almost all shared-memory, concurrent data structures and algorithms, consisting in the efficient allocation and the subsequent reclamation of shared memory resources. This paper contributes a new, lock-free, amortized constant-time memory reclamation scheme called Stamp-it, and compares it to five well-known, selectively efficient schemes from the li...

Each year, wastewater treatment plants in the United States process more than 11.5 trillion gallons of sewage water, enough to fill Utah's Great Salt Lake more than twice. This sewage has the potential to cause catastrophic environmental damage, and it is up to the people who operate the 16,024 wastewater treatment plants in the United States to ensure that it does not harm the lakes, rivers, a...

RC1: Anonymous Referee #1 This small note describes a good experimental dataset collected in two contracted landuse areas. The manuscript has to be amended with hypothetical explanation of processes causing the observed multifractal properties. Otherwise it is purely descriptive narrative that does add to science. The recommendations of soil reclamation have to be substantiated with suggestions...

In Sardinia, as in many other Mediterranean regions, recurrent droughts and climate change have dramatically reduced available water resources. As a result of this critical situation, in 1995 the Italian Government declared a state of emergency and drew up a program for financial support by the State and local authorities with the aim of reducing this serious deficit. One of the actions focused...

JJ.Jiao Land reclamation has played a significant role in the urban development process in many coastal areas in the world. While reclamation provides valuable land, it also creates various coastal engineering, environmental and marine ecological problems. These problems directly caused by reclamation have been well recognized and widely studied. However, it has not been recognized yet that rec...

Presented in this paper is a graphical technique for freshwater and wastewater minimisation in completely batch operations. Water minimisation is achieved through the exploitation of inter- and intra-process water reuse and recycle opportunities. In the context of this paper, a completely batch operation is one in which water reuse or recycle can only be effected either at the start or the end ...
