Quality of wind speed fitting distributions for the urban area of Palermo, Italy
2011
Abstract This study investigates the wind speed characteristics recorded in the urban area of Palermo, in the south of Italy, by a monitoring network composed by four weather stations. This article has two main objectives: the first one, to describe with clarity and simplicity the numerical procedures adopted to perform a preliminary statistical analysis of wind speed data, providing at the same time, the necessary mathematical tools useful to perform this analysis also without special software. The second objective is to verify if there are more suitable probability distributions able to better represent the original data respect the traditional ones. After a preliminary statistical analys…
Sprawa operacyjnego sprawdzenia kryptonim „Zakonnik”. inwigilacja ks. Henryka Surmy przez Służbę Bezpieczeństwa w latach 1974-1977
2018
Celem opracowania jest ukazanie na przykładzie jednego z zakonników sposobu postępowania Służby Bezpieczeństwa wobec duchownych, którzy znaleźli się w spektrum zainteresowania tej instytucji, z uwagi na podejrzenie prowadzenia „antypaństwowej” działalności. Tego rodzaju sprawy operacyjnego sprawdzenia zakładane były przez Służbę Bezpieczeństwa PRL bardzo często i miały na celu sprawdzenie doniesień o prowadzeniu przez duchownych działalności uznawanej przez władze komunistyczne za wrogą ustrojowi PRL. Ks. Henryk Surma, nie godząc się na komunistyczne ograniczenia praw człowieka, ani na dążenia władz PRL zmierzające do marginalizacji Kościoła, próbował na własną rękę pozyskać środki na remon…
Towards an Assessment of Public Library Value
2010
PurposeThis paper aims to present a methodology, early findings, possible applications of results and lessons learned from the research study “Public libraries: value, trust and satisfaction”, which has been conducted within the public library development project ‘Father's Third Son’ in Latvia.Design/methodology/approachA combination of quantitative and qualitative methods was used (although the findings reported here are largely drawn from the quantitative study) drawing on various theories of information behaviour and use‐oriented information service evaluation.FindingsThe study gives a good picture of user information needs in Latvia, the sources they use to fulfil them and the role of p…
Latent Class Approach to Estimate the Willingness to Pay for Transit User Information
2012
The aim of analysis is to understand how unreliable information influences user behaviour and how much it discourages public transport use. For this purpose, a Stated Preference Survey was carried out in order to know the preferences of public transport users relating to information needs and uncertainty on the information provided by Advanced Traveller Information System (ATIS). The perceived uncertainty is defined as information inaccuracy. In our study, we consider- ed the difference between forecasted or scheduled waiting time at the bus stop and/or metro station provided by ATIS, and that experienced by user, to catch the bus and/or metro. A questionnaire was submitted to an appropriat…
Uterine Involvement in Klippel–Trenaunay Syndrome: A Rare But Relevant Event. Review of the Literature
2022
IntroductionKlippel–Trenaunay syndrome (KTS) is a rare vascular congenital disorder characterized by the classical triad of port-wine stains, abnormal growth of soft tissues and bones, and vascular malformations. The involvement of the genitourinary tract and of the uterus in particular is extremely infrequent but relevant for possible consequences.MethodsWe performed an extensive review of the literature using the Pubmed, Scopus and ISI web of knowledge database to identify all cases of KTS with uterine involvement. The search was done using the MeSH term “Klippel–Trenaunay syndrome” AND “uterine” OR “uterus.” We considered publications only in the English language with no limits of time. …
Food predictability determines space use of endangered vultures: implications for management of supplementary feeding.
2013
Understanding space use of free-living endangered animals is key to inform management decisions for conservation planning. Like most scavengers, vultures have evolved under a context of unpredictability of food resources (i.e. exploiting scattered carcasses that are intermittently available). However, the role of predictable sources of food in shaping spatial ecology of vultures has seldom been studied in detail. Here, we quantify the home range of the Egyptian vulture (Neophron percnopterus), a long-lived raptor which has experienced severe population decline throughout its range and is qualified as endangered worldwide. To this end six adults were tracked by satellite telemetry in Spain d…
Structural Vibration Control for a Class of Connected Multistructure Mechanical Systems
2012
Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/942910 A mathematical model to compute the overall vibrational response of connected multistructure mechanical systems is presented. Using the proposed model, structural vibration control strategies for seismic protection of multibuilding systems can be efficiently designed. Particular attention is paid to the design of control configurations that combine passive interbuilding dampers with local feedback control systems implemented in the buildings. These hybrid active-passive control strategies possess the good properties of passive contro…
Discrete-time multioverlapping controller design for structural vibration control of tall buildings under seismic excitation
2012
Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/636878 In this paper, a computationally effective strategy to obtain multioverlapping controllers via the Inclusion Principle is applied to design discrete-time state-feedback multioverlapping LQR con- trollers for seismic protection of tall buildings. To compute the corresponding control actions, the proposed semidecentralized controllers only require state information from neighboring stories. This particular configuration of information exchange allows introducing a dramatic reduction in the transmission range required for a wireless imp…
Frequency domain control based on quantitative feedback theory for vibration suppression in structures equipped with magnetorheological dampers
2009
This is an author-created, un-copyedited version of an article accepted for publication in Smart Materials and Structures. IOP Publishing Ltd is not responsible for any errors or omissions in this version of the manuscript or any version derived from it. The definitive publisher authenticated version is available online at http://dx.doi.org/10.1088/0964-1726/18/9/095041 This paper addresses the problem of designing quantitative feedback theory (QFT) based controllers for the vibration reduction in a structure equipped with an MR damper. In this way, the controller is designed in the frequency domain and the natural frequencies of the structure can be directly accounted for in the process. T…
Investigation of vehicle crash modeling techniques: theory and application
2013
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-013-5320-3 Creating a mathematical model of a vehicle crash is a task which involves considerations and analysis of different areas which need to be addressed because of the mathematical complexity of a crash event representation. Therefore, to simplify the analysis and enhance the modeling process, in this work, a brief overview of different vehicle crash modeling methodologies is proposed. The acceleration of a colliding vehicle is measured in its center of gravity—this crash pulse contains detailed informati…
