The concept of remote controlling electrical devices is not new; people of today are used to being able to control their household electronic items without making an effort to walk up to the device. In this thesis the aim is to use Bluetooth radio signals instead of the traditional infrared light to achieve the remote control functions. As a test application a Sony Compact Disc player is modified in order to be radio controlled with a standard Ericsson T39 mobile phone used as a remote. Since the test application is rather simple without any special requirements the development of a specific radio communication system has not been considered.

Biomechanical Responses of Human Surrogates under Various Frontal Loading Conditions with an Emphasis on Thoracic Response and Injury ToleranceAlbert, Devon Lee 04 June 2018 (has links)
Frontal motor vehicle collisions (MVCs) resulted in 10,813 fatalities and 937,000 injuries in 2014, which is more than any other type of MVC. In order to mitigate the injuries and fatalities resulting from MVCs, new safety restraint technologies and more biofidelic anthropomorphic test devices (ATDs) have been developed. However, the biofidelity of these new ATDs must be evaluated, and the mechanisms of injury must be understood in order to accurately predict injury. Evaluating the biomechanical response, injury mechanisms, and injury threshold of the thorax are particularly important because the thorax is one of the most frequently injured body regions in MVCs. Furthermore, sustaining a severe thoracic injury in an MVC significantly increases mortality risk.
The overall objective of this dissertation was to evaluate the biomechanical responses of human surrogates under various frontal loading conditions. This objective was divided into three sub-objectives: 1) to evaluate the biofidelity of the current frontal impact ATDs, 2) to evaluate the effect of different safety restraints on occupant responses, and 3) to evaluate rib material properties with respect to sex, age, structural response, and loading history.
In order to meet sub-objectives 1 and 2, full-scale frontal sled tests were performed on three different human surrogates: the 50th percentile male Hybrid III (HIII) ATD, the 50th percentile male Test Device for Human Occupant Restraint (THOR-M) ATD, and approximately 50th percentile male post-mortem human surrogates (PMHS). All surrogates were tested under three safety restraint conditions: knee bolster (KB), KB and steering wheel airbag (KB/SWAB), and knee bolster airbag and SWAB (KBAB/SWAB). The kinematic, lower extremity, abdominal, thoracic, and neck responses were then compared between surrogates and restraint conditions. In order to assess biofidelity, the ATD responses were compared to the PMHS responses. For both the kinematic and thoracic responses, the HIII and THOR-M had comparable biofideltiy. However, the HIII responses were slightly more biofidelic. The ATDs experienced similar lower extremity kinetics, but very different kinetics at the upper and lower neck due to differences in design. Evaluation of the different restraint conditions showed that the SWAB and KBAB both affected injury risk. The SWAB decreased head injury risk for all surrogates, and increased or decreased thoracic injury risk, depending on the surrogate. The KBAB decreased the risk of femur injury, but increased or decreased tibia injury risk depending on the surrogate and injury metric used to predict risk.
In order to meet sub-objective 3, the tensile material properties of human rib cortical bone and the structural properties of whole ribs were quantified at strain rates similar to those observed in frontal impacts. The rib cortical bone underwent coupon tension testing, while the whole ribs underwent bending tests intended to simulate loading from a frontal impact. The rib material properties accounted for less than 50% of the variation observed in the whole rib structural properties, indicating that other factors, such as rib geometry, were also influencing the structural response of whole ribs. Age was significantly negatively correlated with the modulus, yield stress, failure strain, failure stress, plastic strain energy density, and total strain energy density. However, sex did not significantly influence any of the material properties. Cortical bone material properties were quantified from the ribs that underwent the whole rib bending tests and subject-matched, untested (control) ribs in order to evaluate the effect of loading history on material properties. Yield stress and yield strain were the only material properties that were significantly different between the previously tested and control ribs.
The results of this dissertation can guide ATD and safety restrain design. Additionally, this dissertation provides human surrogate response data and rib material property data for the validation of finite element models, which can then be used to evaluate injury mitigation strategies for MVCs. / PHD

Gestaltning av nationell identitet i Avengers : Karaktärsanalys av Iron Man, Captain America och Thor / American national identity in Avengers : Character analysis of Iron Man, Captain America and ThorBuyukada, Utkan January 2021 (has links)
Uppsatsens huvudsakliga syfte är att undersöka hur amerikansk nationell identitet förmedlas i populära filmer. Undersökningen sker genom att analysera tre av de populäraste karaktärerna i de fyra Avengers-filmerna. Karaktärerna som ska analyseras är Iron Man, Captain America och Thor. Benedict Andersons undersökning av hur nationell identitet och nationalism sprids med hjälp av litteratur är förutsättningen för uppsatsen. Utgångspunkten är att populärkultur påverkar tittaren och kan sprida idéer som har verkliga effekter i samhället. I analysen tar effekterna av terrorattacken mot World Trade Center en viktig plats och hur den påverkar uppfattningen av amerikansk nationell identitet i Marvel-filmer narrativt och visuellt. Innan 9/11 var amerikansk nationell identitet stark kopplad till triumfalism och exceptionalism. Trots att terrorattacken påverkar gestaltningen av amerikansk nationell identitet i popkultur så förblir Amerikansk triumfalism och exceptionalism en grundläggande del av amerikansk identitet. Samtidigt undersöks den paradoxala relationen mellan individualism och kollektivism. En gestaltning av gemenskap och individualism präglar filmerna där även regissörers påverkan kan spela roll i det hyperindustrialiserade Marvel-maskineriet.

Låt ingen komma undan : Hanteringen av främmande kroppar i Marvels filmuniversum / Leave none alive : Treating foreign bodies in Marvel's cinematic universeLarsson, Vix January 2017 (has links)
This essay examines the appearance of non-normative bodies in three films from the Marvel Cinematic Universe; The Avengers (2012), Thor: The Dark World (2013) and Avengers: Age of Ultron (2015), in an attempt to find qualities that might suggest queer, non-binary or gender disruptive attributes, in addition to looking at how the movies handle them. Using a combination of feminist film theory, queer theory and discourse analysis, the Otherness of these bodies are put into contrast with the normative and hegemonic gender expressions employed by the protagonists, the heroes of the films. While the study finds several indications of transgressive bodies and 'gender ambiguity' among the creatures and beings who play the part of inhuman threat, as well as the presence of discourses that paint them as threatening partly because of these qualities, they remain blurred and ill-defined, their queerness inferred rather than overt. The preferred reading, the analysis suggests, offers little in the way of identification, but all the more with regard to oppression. The way these bodies are treated in all three films implies that the tolerance for bodily deviance is virtually non-existent, and that a defining quality of masculine leadership is the ability to banish them from existence.

Klassiskt och nordiskt : fornnordiska motiv i bildkonsten 1775-1855 / The classical and the Nordic : Old Norse motifs in art 1775-1855Hansson, Nora January 2020 (has links)
The subject of this master’s thesis is depictions of Old Norse mythology and related motifs in the visual arts during the period 1775–1855. The main question of this research is how the motifs were visualized and how the depictions are related to the classical tradition. Three artworks are objects of detailed study: Johann Heinrich Füssli’s painting Thor Battering the Midgaard serpent (1790), Christoffer Wilhelm Eckersberg’s The death of Balder (1817) and Nils Jacob Blommér’s painting Näcken and the daughters of Ägir (1850). The paintings are compared with literary sources and analyzed in relation to classicism as well as ideas about history and the Old Norse. It is argued that symbols, themes and compositions from the classical tradition, such as the heroic nude, were used by artists to visualize motifs from Old Norse mythology. It is also argued that the depictions, which by previous scholars have been considered primarily classical, are in fact characterized by a resistance against likeness with the Olympic gods and antique costume.
