Human Behavior and Urban Open Spaces in Hyper-Dense Areas: The Case of Dhiesheh Refugee Camp-Palestine
2010
Most of the world cities have hyperdense areas within its borders. Hyperdensity can appear in an informal settlement, in a slum area, in an old core, in a city center, or in a camp as in the case of Palestinian refugee camps. Hyperdensity conditions are capable to produce plenty of problems and questions related to the built up environment, quality of life, and people needs. This dissertation is based on exploring the combination between the physical form of urban open space and human behavior to investigate people's needs in urban open spaces of a hyperdense environment. The focus will be on Dheisheh refugee camp within Bethlehem city borders in the West Bank. The research is based on qual…
On The Maximum Number of Abelian Squares in a Word
2014
Strings (aka sequences or words) form the most basic and natural data structure. They occur whenever information is electronically transmitted (as bit streams), when natural language text is spoken or written down (as words over, for example, the Latin alphabet), in the process of heredity transmission in living cells (through DNA sequences) or the protein synthesis (assequence of amino acids), and in many more different contexts
Words, Trees and Automata Minimization
2013
In this paper we explore some connections between some combinatorial properties of words and the study of extremal cases of the automata minimization process. An intermediate role is played by the notion od word trees for which some properties of words are generalized. In particular, we describe an infinite family of binary automata, called word automata and constructed by using standard sturmian words and more specifically Fibonacci words, that represent the extremal case of some well known automata minimization algorithms, such as Moore’s and Hopcroft’s methods. As well as giving an overview of the main results in this context, the main purpose of this paper is to prove that, even if a re…
Epichristoffel Words and Minimization of Moore Automata
2014
This paper is focused on the connection between the combinatorics of words and minimization of automata. The three main ingredients are the epichristoffel words, Moore automata and a variant of Hopcroft’s algorithm for their minimization. Epichristoffel words defined in [14] generalize some properties of circular sturmian words. Here we prove a factorization property and the existence of the reduction tree, that uniquely identifies the structure of the word. Furthermore, in the paper we investigate the problem of the minimization of Moore automata by defining a variant of Hopcroft’s minimization algorithm. The use of this variant makes simpler the computation of the running time and consequ…
Evaluation through adaptive model (ATC) in the levels of thermal comfort in summer in offices in Mediterranea locations.
2014
The design of the building-plant system in the case of office buildings has rarely considered the adaptive model of comfort almost always limited to the control of temperature and humidity and only in some cases of PMV and PPD. Specifically when the building interacts with a climate characterized by high values of external temperature and humidity for long periods, and with high solar radiation in the presence of large glazed areas, it is crucial to take into account relevant aspects of the principle of thermal adaptation. The long stay of the occupants in an air-conditioned environment leads, at the request of colder temperatures very distant from those indicated by the criteria of accepta…
INVERTER-BASED DISTRIBUTED GENERATORS, MODELING AND CONTROL
In the last few years, electrical power generation is moving from a centralized generation towards distributed generation including on-site Renewable Energy Sources (RESs). In order to overcome RES related issues, as intermittent and fluctuating power, storage elements are included in the on-site generation system. The interaction between distributed generator (DG) units including RES, storage and front-end power converters should be carefully modeled in order to analyze the power system stability. An accurate modeling of DGs is required. In this thesis, a new modeling approach has been proposed for the inverter-based DGs based on the concept of electrostatic synchronous machines. Detailed …
Composition of SIFT features for robust image representation
2010
In this paper we propose a novel feature based on SIFT (Scale Invariant Feature Transform) algorithm1 for the robust representation of local visual contents. SIFT features have raised much interest for their power of description of visual content characterizing punctual information against variation of luminance and change of viewpoint and they are very useful to capture local information. For a single image hundreds of keypoints are found and they are particularly suitable for tasks dealing with image registration or image matching. In this work we stretched the spatial coverage of descriptors creating a novel feature as composition of keypoints present in an image region while maintaining…
A New Class of Searchable and Provably Highly Compressible String Transformations
2019
The Burrows-Wheeler Transform is a string transformation that plays a fundamental role for the design of self-indexing compressed data structures. Over the years, researchers have successfully extended this transformation outside the domains of strings. However, efforts to find non-trivial alternatives of the original, now 25 years old, Burrows-Wheeler string transformation have met limited success. In this paper we bring new lymph to this area by introducing a whole new family of transformations that have all the "myriad virtues" of the BWT: they can be computed and inverted in linear time, they produce provably highly compressible strings, and they support linear time pattern search direc…
La tutela reale nel lavoro pubblico tra dottrina, giurisprudenza e riforma Madia
2018
L’articolo si ripropone di analizzare il dibattito dottrinale e giurisprudenziale che è all’origine del mantenimento per via legislativa della tutela reintegratoria in caso di licenziamento illegittimo nel settore pubblico (d.lgs. n. 75/2017). Il saggio si basa su un’analisi giuridico-normativa del nuovo testo dell’art. 63 del d.lgs. n. 165/2001 e su una rassegna delle posizioni dottrinali e giurisprudenziali che lo hanno ispirato. Nella parte finale della ricerca viene messa in evidenza l’ampia distanza che, a seguito della riforma dei licenziamenti, caratterizza ormai il rapporto tra il lavoro pubblico e quello privato, in aperta contraddizione con gli obbiettivi del processo di privatizz…
Sul cd. Fragmentum Dositheanum
2021
Through a special examination of some features of the text commonly referred to as Fragmentum Dositheanum, the author argues that, despite the reference in a paragraph to the knowledge of ‘regulae’, the classical jurisprudential work from which the fragment is taken was not a book of regulae, but an elementary work of a close scholastic nature; moreover, according to the author, this scholastic work might be Gaius’ Res cottidianae.
