Resource allocation and leveling are among the top challenges in project management. Due to the complexity of projects, resource allocation and leveling have been dealt with as two distinct subproblems solved mainly using heuristic procedures that cannot guarantee optimum solutions. In this paper, improvements are proposed to resource allocation and leveling heuristics, and the Genetic Algorith...

This paper is an attempt to shed light on the effects of modernization, urbanization, monolingual educational system, and mass media as well as the process of globalization on dialect leveling among Persian dialects. In so doing, the first part of the paper elaborates on the relationship between globalization and sociolinguistics, and on the concept of standardization. Also, it discusses some ...

The tunneling model has enjoyed considerable success in describing the low temperature properties of glasses. However, departures from the tunneling model have been noted in experiments at very low temperatures (below 100 mK). We have measured the change in the sound speed V/V0 between 1 and 40 mK in an amorphous silica double paddle oscillator oscillating at 14 kHz. Most importantly, the sound...

Over the past 25 years California has transformed its system of public school finance from one of the least equitable in the nation to one of the most equitable. This paper examines the impact of that transformation on housing values. Specifically, we use data on residential housing sales from Los Angeles County for the years 1975, 1980, 1985, and 1990, to answer three fundamental questions rel...

Flash memories are widely used in computer systems ranging from embedded systems to workstations and servers to digital cameras and mobile phones. The memory cells of flash devices can sonly endure a limited number of write cycles, usually between 10,000 and 1,000,000. Furthermore, cells containing data must be erased before they can store new data, and erasure operations erase large blocks of ...

Subject of this paper is the comparison of the results obtained exploiting the Permanent Scatterers (PS) Technique on ERS DInSAR data with displacement measurements carried out by means of optical leveling and GPS.

The nickel-manganese (Ni-Mn) alloy coating prepared from DC electrodeposition process in sulphamate bath was studied. The effects of process parameters, such as current density and electrolyte composition, on the cathodic current efficiency, microstructure, internal stress and mechanical properties were investigated. Because of its crucial effect on the application to the electroforming of micr...

A radical, new innovation with regards to forestry machines is the design of a cab suspended from an arched column connected to a swiveling socket. The purpose of the design is to reduce the amount of skewed and twisted work postures, which are often frequent among operators of logging machines. The ability to sit straight is what most operators point out to be the most desirable feature of the...
