In project scheduling, many problems can arise when resource fluctuations are beyond acceptable limits. To overcome this, mathematical techniques have been developed for leveling resources. However, these produce a hard and inflexible approach in scheduling projects. The authors propose a simple resource leveling approach that can be used in scheduling projects with multi-mode execution activit...

This paper introduces a kind of mechanical structure and its control system, with which granular materials can be put into mould with a higher leveling status, the mechanical structure adopts split type arrangement, its function is to achieve the material removal and scraping, its control system is composed of a plurality of Mitsubishi PLC using masterslave control method. The mechanism and con...

We consider the mid-term production planning problem in make-to-order production, which consists in scheduling production orders so that the variability in the resource utilization over time is minimized. The problem is modeled as a resource leveling project scheduling problem, where production orders for final products and main components correspond to activities of a project. We present a ne...

A linear analysis, employing the lubrication approximation, is presented for the leveling history of a thin layer of Newtonian liquid. When the surface tension is taken to be constant, the classic result of Orchard is reproduced. As expected, the presence of surfactant, with resulting surface-tension-gradient forces, slows the rate of leveling of an initial train of periodic ripples. For very w...

We present results on the leveling of polymer microdroplets on thin films prepared from the same material. In particular, we explore the crossover from a droplet spreading on an infinitesimally thin film (Tanner's law regime) to that of a droplet leveling on a film thicker than the droplet itself. In both regimes, the droplet's excess surface area decreases towards the equilibrium configuration...

By microscopically observing widely used data files, we identified the considerable room for life time improvement in NAND flash memory, which is due to the discovery of a non-uniformity in bit-level data patterns. In an attempt to exploit the discovery, we propose a novel bit-level wear-leveling scheme. Instead of considering only the view of page-level or block-level, we incorporate the nonun...

The very high luminosity foreseen for the LHC luminosity upgrade entails in all cases a significant luminosity decrease during a few hours run. We present in this note a new method of luminosity leveling, based on the on-line adjustment of the crossing angle, while keeping the optics unchanged. It is implemented using the D0 dipole of a possible Early Separation Scheme and an orbit corrector. T...

determinants of the adoption of land leveling in fars province were investigated through an application of logit model to data collected from a sample of 300 farmers. the results revealed that area under cultivation, farmers' education, earnings beside-farm-income, access to credits, availability of laser applied land leveling instruments and equipments in the region, as well as dam water,...

The wear leveling is a critical factor which significantly impacts the lifetime and the performance of flash storage systems. To extend lifespan and reduce memory requirements, this paper proposed an efficient wear leveling without substantially increasing overhead and without modifying Flash Translation Layer (FTL) for huge-capacity flash storage systems, which is based on selective replacemen...

OBJECTIVE This study aimed at comparing the distocervical angulations of upper second molars crowns of groups with normal occlusion and with Angle Classes I and II malocclusions. Additionally, it aimed to analyze the changes occurring after alignment and leveling performed with MBT technique. METHODS The sample of normal occlusions comprised 32 lateral teleradiographs, while the sample of mal...
