This paper introduces a deterministic fluid model that approximates the many-server Gt/GI/st + GI queueing model, and determines the time-dependent performance functions. The fluid model has time-varying arrival rate and service capacity, abandonment from queue, and non-exponential service and patience distributions. Two key assumptions are that: (i) the system alternates between overloaded and...

or Real An important characteristic of maps is the fact that they represent selections from reality in an abstract way. Especially for presentation purposes, maps that look ‘empty’ might even work better than maps with an overloaded view. In an exploratory mode, an overloaded map could be very representative for the topic being studied, and via interactive selection and filtering techniques the...

In this paper, we propose an overloaded multiple-input multiple-output (MIMO) signal detection scheme with slab decoding and lattice reduction (LR). The proposed scheme firstly splits the transmitted signal vector into two parts, the post-voting vector composed of the same number of signal elements as that of receive antennas, and the pre-voting vector composed of the remaining elements. Second...

In object-oriented languages, overloaded methods with multiple dispatch extend the functionality of existing classes, and multiple inheritance allows a class to reuse code in multiple classes. However, both multiple dispatch and multiple inheritance introduce the possibility of ambiguous method calls that cannot be resolved at run time. To guarantee no ambiguous calls at run time, the overloade...

This paper addresses the problem of analyzing performance of WWW servers. The web has experienced a phenomenal growth and has become the most popular Internet application. As a consequence of its large popularity, the Internet has suffered from various performance problems, such as network congestion and overloaded servers. These days, it is not uncommon to find servers refusing connections bec...

Cytoplasmic calcium fluctuations were studied in calcium overloaded Xenopus oocytes. Calcium sensitive chloride currents were recorded using the two-electrode voltage clamp technique. Fluctuations of chloride currents measured under the voltage clamp were elicited by injection of calcium into the cytoplasm. Contrary to infrequent injections of small calcium amounts which evoke smooth transient ...

With the development of cloud computing, mobile device and industry automation, virtualization plays an important role today. The core of virtualization is hypervisor which directly determines the performance of platform. Therefore, how to allocate resource effectively becomes an important issue. Xen, one of widely used open source projects, is a virtual machine monitor. Simple EDF (Earliest De...

This paper explains novel CPU scheduling approach for embedded operating Systems. In this approach we have used genetic algorithm (GA). Proposed Adaptive algorithm combines both EDF and GA based algorithms, Basically the new algorithm uses EDF algorithm but when the system becomes overloaded, it will switch to GA based scheduling algorithm. Again, when the overload disappears, the system will s...

A bstract. An immunohistochemical study using monoclonal antibodies specific for the heavy chains ofeither human atrial (HCa) or ventricular (HC(#) myosin was performed to clarify the distribution ofeach isozyme in normal as well as pressure-overloaded human hearts. In normal human ventricles, all muscle fibers were stained by a monoclonal antibody (HMC14) specific for HC(, whereas a small numb...
