Dropping probability of handoff calls and blocking probability of new calls are two important QoS measures for cellular networks. Since the dropping probability of handoff calls is more important, call admission policies are used to maintain the upper bound of dropping probability of handoff calls. The fractional channel policy (FC) is a general call admission policy and includes most prioritiz...

Recently, many people enjoy accessing wireless network to conveniently collect their required information or happily surf within the Internet worldwide by exploiting wireless mobility, flexibility and availability. However, the more sessions accessing the channel, the more packet dropping rate. In this paper, we propose a polling access control scheme which in its PCF mode deploys non-preemptiv...

A recently proposed global congestion measure for CDMA networks is applied to call admission control, call dropping, and band allocation in multi-carrier CDMA networks. It is shown to perform comparably with existing techniques for call dropping, and better than existing techniques for admission control and band allocation. Difficulties arising in the measurement of this parameter are also inve...

Drag and drop operation is one of the key capabilities of any Graphical User Interface. The user can do quite complex operations simply by visually dragging and dropping objects from one location to another. It saves user from remembering and typing a lot of commands. The result of a drag and drop operation may vary depending the type of source object and type of destination object. For example...

Regression discontinuity designs are extensively used for causal inference in observational studies. However, they usually confined to settings with simple treatment rules and determined by a single running variable cutoff. Motivated the problem of estimating impact grade retention on educational juvenile crime outcomes Chile, we propose framework methods complex that encompass multiple rules. ...

As children hear a novel verb in a NOUN-VERB-NOUN (i.e., NVN) structure, they generally infer that the verb is transitive, like the verb “hit” (Naigles, 1990; Yuan, Fisher, & Snedeker, 2012). However, the relationship between sentence structure and a verb’s transitivity status is not straightforward. Particularly, in typologically pro-drop languages, such as Mandarin Chinese, the object in a se...

maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...
