Virtual Prototypes (VPs) are currently substituting physical ones in some activities of the product development process, being more flexible, sharable and easy to modify. Several companies that currently make use of this practice have put effort in the improvement of visualization techniques and of the level of quality of the information that is visually represented, which is indeed very high. ...

Product Lifecycle Management business approach goals have always been key to foster product innovation and companies’ competitive advantage through effective Intellectual Property creation, evolution and reuse management to successfully transition into successful product manufacturing and operations, taking into account the whole product lifecycle and its evolution through changes or derived pr...

Professor Utkin in his discussion paper proposed an example showing that the amplitude of chattering caused by the presence of parasitic dynamics in systems governed by FirstOrder Sliding-Mode Control (FOSMC) is lower than the obtained using Super-Twisting Algorithm (STA). This example served to motivate this research reconsidering the problem of comparison of chattering magnitude in systems go...

In this paper, we present a mathematical model that describes the calcination and sintering of calcium-based sorbents in furnace sorbent injection (FSI) conditions. We assumed that the sorbent decomposition follows a shrinking core model with a changing pore size distribution in every layer and we used a comprehensive mathematical model for sintering. Cylindrical and plate-like or slit pore geo...

Information filtering techniques have been continuously developed to meet challenges arisen from new requirements of Information Society. These techniques gain even much more on importance in the facet of grater mobility of people. One of the most dynamic and compelling areas is the environment of wireless and mobile devices. Just recently, information filtering and retrieval have begun to take...

Tuberculosis (TB) is one of the oldest, the most expanded and the most lethal diseases in human history. Although Koch's discovery of the TB causative agent (1882) represented a great progress in the fight against this infectious disease, it took a significant amount of time to reduce morbidity and mortality in the world. In Bosnia and Herzegovina (B&H) it was necessary to implement actions in ...

Headwater streams support vital aquatic habitat yet are vulnerable to changing climate due their high elevation and small size. Coldwater fish especially sensitive the altered streamflow water temperature regimes during summer low flow periods. Though previous studies have provided insights on how changes in alterations stream discharge may affect availability for various native cutthroat trout...

In craniospinal irradiation, field matching is very sensitive to intrafraction positional uncertainties in cranio-caudal direction, which could lead severe overdoses/underdoses inside the planning target volume. During last decade, significant efforts were made develop volumetric-modulated arc therapy strategies, less setup uncertainties. this study, a treatment system-integrated method, named ...

The production cassava ( Manihot esculenta ) is considered an important alternative to reduction in food scarcity around the world. In Kenya, it rapidly gaining prominence due declining of staple foods, especially maize and wheat. Though still a poor man’s food, usage has greatly diversified terms both industrial domestic applications. This coupled with introduction improved varieties better fa...
