In this thesis the polyester dyeing at low temperatures has been assessed with two different methods: exhaustion method and thermosol method. Exhaustion dyeing process was performed with high and low molecular-weight ...
Vegetable production in greenhouses is an important and productive economic activity for agricultural businesses in Southern Europe. One of the most risky factors affecting this activity is the use of plant protection ...
Es defineix un satèl·lit d'òrbita baixa aquell que es troba a una alçada de fins a 2000 km per sobre de la superfície de la Terra. Degut al ràpid decaïment dels objectes propers a la superfície degut al fregament atmosfèric, ...
This thesis is mainly devoted to the investigation of speed control methods for three phase cage induction motors with particular emphasis being given to Direct Torque Control (DTC) improved techniques.<br/>Classical Direct ...
Alignment or registration of medical images has a relevant role on clinical diagnostic and treatment decisions as well as in research settings. With the advent of new technologies for multimodal imaging, robust registration ...
Over the last decades, wireless technologies have become an important part of our daily lives. A plentitude of new types of networks based on wireless technologies have emerged, often replacing wired solutions. In this ...
In the field of computer animation the process of creating an animated character is usually a long and tedious task. An animation character is usually efined by a 3D mesh (a set of triangles in the space) that gives its ...
The evolution of microprocessor design in the last few decades has changed significantly, moving from simple inorder single core architectures to superscalar and vector architectures in order to extract the maximum available ...
High-throughput real-time Big Data stream processing requires fast incremental algorithms that keep models consistent with most recent data. In this scenario, Hoeffding Trees are considered the state-of-the-art single ...
Computer architects are beginning to embrace heterogeneous systems as an effective method to utilize increases in transistor densities for executing a diverse range of workloads under varying performance and energy ...
(English) Coastal areas support important ecosystems with great ecological value, giving rise to countless resources increasingly exploited by humans. Understanding the processes occurring in both inland and aquatic ...
Very Long Instruction Word (VLIW) processors are very popular in embedded and mobile computing domain. Use of VLIW processors range from Digital Signal Processors (DSPs) found in a plethora of communication and multimedia ...
(English) This thesis makes a significant contribution to the realm of medical diagnostics through the utilization of photonic technologies and emerging imaging modalities, leading to the creation of innovative approaches ...
Recently, high performance processor designs have evolved toward Chip-Multiprocessor (CMP) architectures to deal with instruction level parallelism limitations and, more important, to manage the power consumption that is ...
In recent years there has been an extraordinary growth of the Internet of Things (IoT) and its protocols. The increasing diffusion of electronic devices with identification, computing and communication capabilities is ...
With the arrival of free on-line machine translation (MT) systems, came the possibility to improve automatic translations with the help of daily users. One of the methods to achieve such improvements is to ask to users ...
This thesis presents cross-domain approaches that improve the effective use of multithreaded architectures. The contributions of the thesis can be classified in three groups. First, we propose several methods for thread ...
Increasing processors' clock frequency has traditionally been one of the largest drivers of performance improvements for computing systems. In the first half of the 2000s, however, it became clear that continuing to increase ...
Virtual memory improves programmer productivity, enhances process security, and increases memory utilization. However, virtual memory requires an address translation from the virtual to the physical address space on every ...
(English) Bone is the second most frequent tissue transplantation right after blood transfusion. Although it has natural self-healing abilities, bone grafts are required in critical size defects to provide mechanical ...
