The goal of resource leveling is to minimize the deviation between the resource requirements and the desired resource profile to prevent problems that caused by fluctuation of required resources. It is a common problem and arises frequently in real situations and therefore has been studied numerous times. Almost in all of these studies and the resulting solutions, there exist a common element, ...

In radar images, point scatterers provide reflections that can often be attributed to a single physical object, usually smaller than the resolution cell size. Stable point scatterers with high backscatter coefficients through time (mainly ’man-made features’) are potential targets for InSAR deformation analysis. A-priori knowledge about the observation statistics of InSAR point scatterer measur...

The purpose of this study was to compare the effects of active and passive lacebacks on antero-posterior position of maxillary first molars and central incisors during leveling phase. Twenty-three subjects with Class I and Class II malocclusion were treated with first premolars extraction using preadjusted appliances (MBT 0.022-inch brackets). The leveling phase was performed with stainless ste...

We describe the design, development and initial evaluation of an interactive virtual environment whose objective is to help undergraduate students learn and review the concepts and practices of differential leveling. The virtual environment, which includes realistic terrains and leveling instruments that look, operate, and produce results comparable to the physical ones, is not meant to replace...

INTRODUCTION A wide variety of orthodontic wires made of different alloys is available to be used in orthodontic practice and may produce different clinical responses during tooth movement. OBJECTIVE This research evaluated the alignment and leveling of lower dental arches after the use of three types of orthodontic wires. METHODS A sample of 36 patients was randomly divided into 3 groups: ...

To select the best geo-potential model for the determination of Hong Kong and Shenzhen local geoids, three models EGM96, WDM94 and GPM98CR were tested in the region using GPS/leveling data and gravity measurements. The data include GPS/leveling observations at 43 stations, 640 gravity measurements covering the whole territory of Hong Kong, and 62 high precision GPS/leveling observations and 487...

Synthetic Aperture Radar Interferometry (InSAR) techniques are increasingly applied for monitoring land subsidence. The advantages of InSAR include high accuracy and the ability to cover large areas; nevertheless, research validating the use of InSAR on building deformation is limited. In this paper, we test the monitoring capability of the InSAR in experiments using two landmark buildings; the...

INTRODUCTION The orthodontic technique favored by a clinician frequently determines how a deep curve of Spee (COS) is leveled. The primary purpose of this investigation was to confirm radiographically the long-term effectiveness of a continuous archwire technique--the Alexander discipline--in leveling the COS in patients with Class II Division 1 deep-bite malocclusions treated without extractio...

OBJECTIVE To develop and test the reliability of a case-leveling framework for assigning level of difficulty of the pharmacist's task for initial medication assessments conducted by pharmacists integrated into family physician offices. DESIGN Descriptive study. SETTING Seven family practice sites in Ontario from June 2004 to July 2006. PATIENTS Patients referred by their family physician ...

many new technologies have been employed to improve welfare conditions and to provide an optimum utilization of the existing resources in agriculture sector. laser leveling technology is one of the most progressed in maintenance of soil and water resources which itself has an important role in sustainable development. the purpose of this study was to realize the specifications of adopters vs. n...
