Integrating passive ubiquitous surfaces into human-computer interaction

Mobile technologies enable people to interact with computers ubiquitously. This dissertation investigates how ordinary, ubiquitous surfaces can be integrated into human-computer interaction to extend the interaction space beyond the edge of the display. It turns out that acoustic and tactile features generated during an interaction can be combined to identify input events, the user, and the surface. In addition, it is shown that a heterogeneous distribution of different surfaces is particularly suitable for realizing versatile interaction modalities. However, privacy concerns must be considered when selecting sensors, and context can be crucial in determining whether and what interaction to perform.Mobile Technologien ermöglichen den Menschen eine allgegenwärtige Interaktion mit Computern. Diese Dissertation untersucht, wie gewöhnliche, allgegenwärtige Oberflächen in die Mensch-Computer-Interaktion integriert werden können, um den Interaktionsraum über den Rand des Displays hinaus zu erweitern. Es stellt sich heraus, dass akustische und taktile Merkmale, die während einer Interaktion erzeugt werden, kombiniert werden können, um Eingabeereignisse, den Benutzer und die Oberfläche zu identifizieren. Darüber hinaus wird gezeigt, dass eine heterogene Verteilung verschiedener Oberflächen besonders geeignet ist, um vielfältige Interaktionsmodalitäten zu realisieren. Bei der Auswahl der Sensoren müssen jedoch Datenschutzaspekte berücksichtigt werden, und der Kontext kann entscheidend dafür sein, ob und welche Interaktion durchgeführt werden soll

A novel approach to measure, understand, and assess the thermal environment in grow-finish swine facilities

The thermal environment (TE) inside swine production systems substantially affects animal performance as well as facility natural resource usage; hence, our measurement, understanding, and assessment of the TE must be advanced to sustainably meet the animal-protein demand of the growing global population. The TE describes the parameters that influence heat exchange between an animal and its surroundings, with maximum animal performance achieved when minimal thermoregulatory effort is required. Instrumentation and analysis techniques connecting the impact of the TE on total heat loss and subsequently, to animal performance in intensive housing systems are limited. Therefore, the goals of this dissertation research were to create a novel measurement system for quantifying the TE, develop a mechanistic model to understand the interaction between pigs and their TE, and lastly, establish the methodology to assess the TE for improved management strategies. This dissertation describes the design, validation, and implementation of an innovative TE sensor array (TESA) featuring dry-bulb and black globe temperature, airspeed, and relative humidity measurements. A low-cost omnidirectional thermal anemometer was engineered and calibrated with documented measurement uncertainty for reliable airspeed measurements. These measured parameters were needed as inputs to estimate the convective, radiative, and evaporative modes of heat loss in the developed model, which simulated the cascade of behavioral and physiological thermoregulatory responses of group-housed, grow-finish pigs as a function of the TE. Model results were used to generate a new thermal index for assessing different combinations of the TE and predicting the subsequent impact on animal performance. This index was applied to spatially and temporally analyze data collected from a network of 44 TESAs deployed symmetrically in two rooms of a commercial swine facility. TESA adds a new level of measurement precision greatly needed in modern facilities and goes beyond solely measuring dry-bulb temperature. The testing and calibration of TESA demonstrates the functional performance capabilities of the instrument and sets the standard for animal production sensor development. The mechanistic model provides reasonable agreement with previously published results and can be used to inexpensively explore different combinations of the TE on swine performance. Overall, this dissertation will help the swine industry by providing new technology and methods to quantify the impact of TE on performance for improved housing system management and control decisions. This dissertation will advance the corpus of knowledge required to provide food security for the growing global population through economically and sustainably housed pigs

Agricultural engineering

Believing that the study of Agricultural Engineering should fill an important place in the training of the young man who would make farming the object of his life\u27s work, the author has attempted to furnish in this volume an aid in supplying this part of his training. The application of agricultural engineering methods to agriculture should not only raise the efficiency of the farm worker but should also provide for hlm a more comfortable and healthful home. This volume has been written primarily as a text for secondary schools of agriculture, and for colleges where only a generaf course can be offered. Claim is not made for much new material concerning the subjects discussed; but rather an attempt has ·been made to place under one cover a general discussion of agricultural engineering subjects which hitherto could not be secured except in several volumes and hence impractical for text-book purposes.https://lib.dr.iastate.edu/abe_eng_books/1001/thumbnail.jp
