In this paper, we describe the design and development of an interactive virtual environment whose objective is to help undergraduate students learn and review the concept and practices of differential leveling. The virtual environment includes realistic terrains and leveling instruments that look, operate, and produce results comparable to the physical ones. It will be integrated in surveying c...

The following paper will describe a methodology for automatically detecting and diagnosing rolling element bearing wear. The techniques involved have been proven in over 15 years of use in a huge variety of environments, machine types and applications. The techniques involved in diagnosing bearing wear will be described in detail and supported by a set of example graphs and an annotated diagnos...

Despite the numerous benefits of formal mentorship for all faculty, it remains underutilized within academy. Specifically, this lack critical support leaves historically marginalized groups, particularly women, underrepresented minorities, as well part-time, intermittent, adjunct, or non-tenure track to struggle with navigating challenging climate higher education. To counter these inherent pow...

This paper explains an implementation model for a new method for Production Leveling designed for batch production system. The main structure of this model is grounded on three constructs: traditional framework for Operations Planning, Lean Manufacturing concepts for Production Leveling and case study guidelines. By combining the first and second construct, a framework for Production Leveling h...

In this paper we present a new algorithm for leveling a discrete terrain using autonomous agents of minimal complexity. Our primary interest is in developing robust strategies for eventual application in underwater construction. Terrain leveling underwater typically involves the use of large and expensive machinery that may be cumbersome to operate. We propose that a swarm of autonomous robots ...

In this paper a new method based on fuzzy theory is developed to solve the Project Resource Leveling Problem in fuzzy environment. Resource Leveling Problem attempts to minimize the resource usage fluctuations in project plan. Assuming that the duration of activities and resource requirements are fuzzy, in this method we compute several project characteristics such as earliest times, latest tim...

nowadays, combination of gps heights with orthometric heights, derived from precise leveling, is broadly used to obtain point-wise solutions of the geoid, which is called “gps/leveling geoid”. the “gps/leveling geoid” is commonly used to constrain the gravimetric geoid solutions in a least squares surface fitting process. in this paper, unlike the usual application, the “gps/leveling geoid” is ...

Coal mining subsidence seriously affects the mine natural and ecological environment. Leveling is the traditional method to monitor the coal mining subsidence. It is possible to monitor the subsidence by gravimetry instead of leveling based on the negative linear correlation between the gravity change and the height change. Equations are derived to monitor the subsidence by gravimetry in the pa...

The project scheduling and resource allocation problems have been studied using different optimization methods. The resource leveling problem was proposed to reduce the resource fluctuation and was always studied independently resource constraint problem. For example, resource-constrained project scheduling problem (RCPSP) was proposed to optimize scheduling under resource constraints. This res...
