The use of 3D (3 Dimensional) Virtual Environments is gaining interest in the context of academic discussions on E-learning technologies, as it provides several advantages over classical learning material. However, the use of 3D for learning environments also has drawbacks, especially usability and the effectiveness may cause problems. One way to overcome these drawbacks is by providing an adap...

Abstract The Singleton pattern [1] is a solution to (some of) the drawbacks of using global variables. Among its advantages is that the instance is always created prior to being referenced (this effectively solves the problem of initialization order when several interdependent instances are involved). This article examines some of the existing Singleton realizations in C++ and their drawbacks, ...

The synthesis of biodiesel fuel from lipids (vegetable oils and animal fats) has gained in importance as a possible source of renewable non-fossil energy in an attempt to reduce our dependence on petroleum-based fuels. The catalytic processes commonly used for the production of biodiesel fuel present a series of limitations and drawbacks, among them the high energy consumption required for comp...

As technology scaling becomes increasing more difficult, other venues such as decreasing operation temperature have offered further improvement in circuits. This paper presents the advantages of low (liquid nitrogen or LN) temperature have on CMOS circuits as well as a survey of current applications. Motivation for low temperature electronics (LTE) has risen further from the prominent drawbacks...

We discuss the use of both MPI and OpenMP in the teaching of senior undergraduate and junior graduate classes in parallel programming. We briefly introduce the OpenMP standard and discuss why we have chosen to use it in parallel programming classes. Advantages of using OpenMP over message passing methods are discussed. We also include a brief enumeration of some of the drawbacks of using OpenMP...

Tensor factorization with hard and/or soft constraints has played an important role in signal processing and data analysis. However, existing algorithms for constrained tensor factorization have two drawbacks: (i) they require matrixinversion; and (ii) they cannot (or at least is very difficult to) handle structured regularizations. We propose a new tensor factorization algorithm that circumven...

In this paper we briefly define distance vector routing algorithms, their advantages and possible drawbacks. On these possible drawbacks, currently widely used methods split horizon and poisoned reverse are defined and compared. The count to infinity problem is specified and it is classified to be a halting problem and a proposition stating that entangled states used in quantum computation can ...

A key technique for the verification of programs is counterexampleguided abstraction refinement (CEGAR). In a previous approach, we developed a CEGAR-based algorithm for the modal μ-calculus, where refinement applies only locally, i.e. lazy abstraction techniques are used. Unfortunately, our previous algorithm was not completely lazy and had some further drawbacks, like a possible local state e...
