The evolution of the Semantic Web (SW) depends on novel methodologies to represent the meanings of the huge amount of information available nowadays. Recent proposals in literature have explored new approaches based on Semiotics. The ‘Semiotic Web Ontology’ (SWO) is an attempt to model the information in a more precise way, and, at the same time to be compatible with the SW standards. This pape...

Primljeno (Received): 2011-10-10 Prihvaćeno (Accepted): 2012-02-09 Original scientific paper It is well-known from practice that only some cups whose height is smaller than diameter can be successfully drawn in one step. Many steps require more tools and larger total manufacturing costs. The main objective of this study was to minimize the number of deep-drawing steps. The paper presents the ap...

The thermally assisted mechanical dewatering process, investigated in this paper, couples in one stage mechanical dewatering at low pressure (Papplied < 1125 kPa) with a moderated heating (T < 80°C). Former studies emphasized that the separation enhancement depends on the product. To identify the mechanisms involved, a 1D filtration/compression cell is instrumented with pore liquid sensors dist...

Cooperative learning has been proven to be helpful in enhancing the learning performance of students. The goal of a cooperative learning group is to maximize all members’ learning, which is accomplished via promoting each other’s success, through assisting, sharing, mentoring, explaining, and encouragement. To achieve the goal of cooperative learning, it is very important to organize well-struc...

Concepts of Operations (CONOPS) are documents describing the characteristics and intended usage of proposed and existing systems. They provide information about the requirements and future desired states the project aims to achieve. We reviewed 22 recent CONOPS from government and private sector institutions to ascertain the current approach to CONOPS development. Based on the CONOPS review and...

Thermally assisted mechanical dewatering (TAMD) is a new process for energy efficient liquid/solids separation which enhances conventional device efficiency. The main idea of this process is to supply a flow of heat in mechanical dewatering processes to favour the reduction of the liquid content. This is not a new idea but the proposed combination, especially the chosen operating conditions (T ...

A route to prepare nitrides, such as GaN, VN, and other nitrides, is reported. The reaction pathway involves a two-step process by using the as-synthesized a-C3N3.69 as precursor. The route is so potent that a series of nitrides can be directly synthesized from their oxides at moderate temperatures. A striking feature of this method lies in that a-C3N3.69 is found to play double roles as both c...

We report herein a new nanoparticlization process for the bulk-to-nano transformation of Ag2S by incorporating both top-down and bottom-up approaches. Bulk Ag2S was dissolved in solution with the assistance of a macrocyclic ligand, hexamethylazacalix[6]pyridine (Py[6]), to produce polynuclear silver sulfide cluster aggregates. All Ag-S cluster aggregates obtained in three crystalline complexes ...

It has been proved that ultrasonic energy can considerably increase the amount of oil recovery in an immiscible displacement process. Although many studies have been performed on investigating the roles of ultrasonic waves, based on the best of our knowledge, little attention has been paid to evaluate wave attenuation parameter, which is an important parameter in the determination of the energy...
