This thesis describes the possibilities of wireless sensor networks in monitoring buildings and summarizes the most common use of wireless sensor networks in practice. There are also described communication protocols needed for communication between each node and properties of topology of created network. Importance is lay on implementation of fully dynamic network with automatic network topology establishment. The application is designed for the TinyOS operating system and hardware platforms MICAz and IRIS, and its task is to establish the topology and send the data obtained from sensors to base station. The implemented protocol is based on the Collection Tree Protocol protocol and using best effort delivery is able to establish a dynamic topology. Further there is described  the method of storage and subsequent graphical and textual representation of data collected.

Thrust into a world of poetry, I’ve grown to embrace the poetic lens. Each topos, each trope, each rhyme, each cliché, each morning morning’s minion, each reduction to a state of almost savage torpor, each nightingale, each ode to an obscure, inanimate object, and every single Stella of the skies holds special significance hidden to the naked eye. Not insamuch as something undiscoverable upon ponderance. Rather, a way to contemplate the physical. The Ah, Sunflower! reaction. That is not to say that poets have a supernatural eyesight to certain beautiful images. My eyes do not see any more dandelion puffs whirl-winding in the sky than others.’ Take the image a step further. The puff of dandelion seeds becomes a floating scoop of ice cream. Dripping sweet nutrients to the field, fostering the growth of new dandelions. So, now we have the permission to kick the field of dandelions and birth more scoops. These words come after my project as they are a reflection of my poetry. There is a step after expressing one’s thoughts into a poem. That is to say, it is important to re-read your poetry once your mind has settled. You can begin to reflect more objectively on your actions that put you into the poetic mindset. In the following pages, I have organized a few stories with deeper philosophical insight than my poems. Like my poems, they are about loss, love, life. But they contain moments of meditation and reflection. Moments in which I engage the reader with what is swimming around my head now that I’ve tried to understand the situation more objectively. But does reflection bring us closer to objectivity? It is common to believe that memory alters and bends the truth. By expressing my emotions ‘in the moment,’ I am lying. My written emotions are more driven by how I’m feeling with the pen in my hand than how I felt before I jumped off a wall and broke my ankle. Yet, this prose sort of writing provides us with a different effect than poetry. Much of my poetry has been a series of images or emotions. Very little self-reflection on cause-and-effect or position in society is explicit. For the most part, I urge the reader to find my thoughts afterwards within my diction, syntax, or rhythm. During this prose section, I will outright express my emotions as they are. Rather than convoluting a failed relationship and describing it as a metaphorical moat, I will say that I feel as if there is a boundary between us now. I will address how frantically I behave when I see her in my peripherals, just dying to get her attention. I will conclude with the reflection that I only set myself up for more disappointment by expecting any kind of positive reaction. The result of these ‘after words’ is more insight on the reader’s end, hopefully. When writing poetry I try to apply sensory images that put the reader in the present moment I am trying to convey. My goal is to give the reader a first-hand view at the experience. My prose attempt to provide the reader with insight to a more reflective mode of expression. While my poems create a comprehensive view on the inner workings of my mind, I expect that this additional prose section will bring the project full circle.

Introduction Symptoms are universally experienced and can be bothersome. There have been comparatively few studies of common symptoms in the UK general population. As a result, little is known about the current epidemiology of common symptoms in the UK. There are major methodological challenges to conducting an epidemiological study of common symptoms in the community. Current knowledge about the most appropriate methodological tools for collecting and interpreting data on symptoms is limited. A range of methods has been used in previous studies, but the most appropriate method is not known. An evaluation of the different methods that could be used for investigating common symptoms in the community was therefore required. Aims The overall aim of this study was to investigate and compare the use of different approaches to collecting epidemiological data on common symptoms, with a view to developing an evidence-base for the use of these different approaches. Methods A general review of methods used in epidemiological studies and a comprehensive review of methods used in previous epidemiological studies of symptoms were undertaken. The reviews informed the development of symptoms survey. Symptoms survey was conducted to collect epidemiological data on common symptoms in the community. A total of 1179 individuals was approached from four GP practices in the Aberdeen area and sent an invitation letter, information sheet and consent form. Potential participants were requested to select at least two data collection instruments from four options (postal questionnaire, diary, online questionnaire and telephone interview). All the instruments collected the same data (presence of symptoms, severity of symptoms, management of symptoms and quality of life). This allowed a direct comparison of the data collected by the various measures. Those agreeing to participate in the study were sent one of their chosen instruments in phase one of the study and a second (but different) one of their chosen instruments in phase two, which was conducted three weeks later.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The Data Acquisition and Distribution System (DADS) transparently collects data from a ship's combat system and transfers that data by satellite to a shore site. The system was developed by the Naval Surface Warfare Center Port Hueneme Division (NSWC PHD). DADS supports surface ship data collection, display, distribution, and debrief capabilities. NSWC PHD personnel used equipment assets developed in-house and purchased data communications hardware and software to develop DADS. A satellite terminal was placed outside Building 1380, and analog telephone lines were installed, linking the Data Communications and Control Laboratory (DCCL) with the Satellite Earth Station in Santa Paula, CA. A shipboard DADS transparently taps a ship's Combat System and collects selected data files. The data is compressed and archived. After shore site personnel select the data required for analysis, DADS encrypts it, and transmits the data via satellite to the shore site for reconstruction and analysis. DADS is unattended. The portable shipboard system equipment and software is controlled from a shore site via the International Maritime Satellite (INMARSAT). The DCC supports transmission speeds of up to 9.6 kilobits/second when connected to a communication system with this capability.

Between craftsmanship and outsourcing - challenges in purchasing literature in languages other than Swedish and English at Swedish public libraries. This paper examines how ten librarians working in Swedish public libraries perceive challenges connected to the acquisition of books in languages other than Swedish and English. It makes an attempt to explain how these challenges affect the librarians’ acquisition process and push it towards either a craftsmanship based process or a process based on a high degree of outsourcing responsibility. The method used was qualitative interviews with librarians that had acquisition of books in languages other than Swedish or English as part of their work responsibilities. A total of eight interviews, two of them group interviews with two participants, were conducted. Five of the interviewed librarians worked in a large city, while five worked in three smaller municipalities. The analysis was inspired by Evans’ & Saponaro’s model of the collection development process and Brian Quinn’s use of George Ritzer’s theory of McDonaldization to examine the state of academic libraries in the U.S.A. Three main challenges are discussed; identifying user needs, absence of language or literature knowledge and poor availability of books. The interviewed librarians acquisition processes could be said to exist on a scale between a high degree of craftsmanship and a high degree of outsourcing. One factor pushing librarians towards an outsourcing of responsibility was absence of language knowledge, which lead to a higher degree of dependency on vendor assessment of literature. Mandatory purchasing agreements and lack of adequate technical and cataloging services inhouse were also factors affecting the acquisition process as they lead to less choice in vendor selection and as a consequence hindered the librarians’ ability to take on responsibility in selecting and acquiring books.
