Parallelization Programming Techniques: Benefits and Drawbacks
"... always a need for more computer resources, apart from which, many computer resources are still unused. The most common resource demanding applications are applications which require a lot of processor power or RAM space. Today, advancing technology offers processing power in grids, clusters, multi-c ..."

-core CPUs, cloud computers, or even graphics processing units. Thus, given all this computing power, smart and efficient utilization of these systems is needed. All these necessities and mentioned facts laid foundation for parallel programming. One of the major issues in parallel programming
A Fast Voxel Traversal Algorithm for Ray Tracing
- In Eurographics ’87
, 1987
"... A fast and simple voxel traversal algorithm through a 3D space partition is introduced. Going from one voxel to its neighbour requires only two floating point comparisons and one floating point addition. Also, multiple ray intersections with objects that are in more than one voxel are eliminated. ..."

. Introduction In recent years, ray tracing has become the algorithm of choice for generating high fidelity images. Its simplicity and elegance allows one to easily model reflection, refraction and shadows. 1 Unfortunately, it has a major drawback: computational expense. The prime reason
Probabilistic Reliable Dissemination in Large-Scale Systems
- IEEE Transactions on Parallel and Distributed Systems
, 2001
"... The growth of the Internet raises new challenges for the design of distributed systems and applications. In the context of group communication protocols, gossip-based schemes have attracted interest as they are scalable, easy to deploy, and resilient to network and process failures. However, tradi ..."

, traditional gossip-based protocols have two major drawbacks: 1) They rely on each peer having knowledge of the global membership and 2) being oblivious to the network topology, they can impose a high load on network links when applied to wide-area settings. In this paper, we provide a theoretical analysis
GRIFFITH THEORY OF BRITTLE FRACTURE REVISITED: MERITS AND DRAWBACKS
"... A variational reformulation of Griffith’s theory of brittle fracture is proposed. At the expense of a slight departure from the classical theory, the new formulation decisively addresses three major issues: crack initiation, crack path, and smoothness of the crack evolution. The new formulation is a ..."

PEER-EDITING PRACTICE IN THE WRITING CLASSROOM: BENEFITS AND DRAWBACKS
"... Small scale studies have shown that peer-editing is beneficial to students as it increases their awareness of the complex process of writing improves their knowledge of and skills in writing and helps them become more autonomous in learning. Teachers too may benefit from peer-editing as this practi ..."

-editing as this practice discloses invaluable information on students' writing weaknesses and strengths; and teachers' teaching effectiveness. This is a small scale study conducted on fifteen first-year degree students majoring in Tourism to view the usefulness of peer-editing practice in enhancing their writing
Pruning and Summarizing the Discovered Associations
, 1999
"... Association rules are a fundamental class of patterns that exist in data. The key strength of association rule mining is its completeness. It finds all associations in the data that satisfy the user specified minimum support and minimum confidence constraints. This strength, however, comes with a ma ..."

major drawback. It often produces a huge number of associations. This is particularly true for data sets whose attributes are highly correlated. The huge number of associations makes it very difficult, if not impossible, for a human user to analyze in order to identify those interesting/useful ones

Potential and Drawbacks of Raman (Micro)Spectrometry for the Understanding of Iron and Steel Corrosion
"... Raman scattering theory and first observation date back to the first decades of the 20th Century but the technique did not generalise until the 70s, with the development of lasers technology. Two major breakthroughs occured in the 80s with the replacement of monochannel PM detectors by multichannel ..."

Spatially coherent latent topic model for concurrent object segmentation and classification
- IN: PROCEEDINGS OF IEEE INTERNATIONAL CONFERENCE ON COMPUTER VISION
, 2007
"... We present a novel generative model for simultaneously recognizing and segmenting object and scene classes. Our model is inspired by the traditional bag of words representation of texts and images as well as a number of related generative models, including probabilistic Latent Sematic Analysis (pL ..."

While such representation provide an efficient computational method, it lacks the power to describe the visually
TECHNOLOGY’S LIMITATIONS: A DRAWBACK IN HEALTHCARE INFORMATION SYSTEMS ’ ACCEPTANCE

Abstract: In the past recent years the introduction of a Hospital Information System in one of the largest state Greek hospitals took place in two phases: First, the Administrative subsystem (AS) was developed and used productively and later on, the Clinical Information subsystem (CIS) gradually was ..."

When the entire project was delivered, it was realized that although the AS was fully operational and totally accepted by the users, that was not the case with the CIS, which was only partially accepted. The majority of the physicians reacted negatively in the use of the system. Many reasons
