La etimología del vasco ezker “izquierdo” (reconstrucción interna)
No full textThe etymology of the Basque word ezker “left” proposed by the author of this study takes a very different line to the theories put forward by A. Tovar, M. Agud, Mahn and Van Eys, which are based on the initial component esku, *esku erdi, *esku oker. The present author identifies ertz oker, ‘twisted edge or end’, as the root form via the phonetic progression ertz oker > *ertzoker > *ertzker > ezker, meaning ‘twisted edge’.Egileak aurkezten duen ezker euskal hitzaren jatorria, A. Tovar - M. Agud, Mahn eta Van Eys hizkuntzalari ospetsuek proposatutako esku sustraitik aldentzen da. Bere ustez, ertz egon daiteke lehen sustraian. Ezker izenlaguna ertz oker iturburutik letorke, *ertzoker > *ertzker > ezker aldaeren bidez. Berezko esanahia “bazter oker” edo antzeko zerbait datekeela dio.La etimología de la palabra vasca ezker “izquierdo” que propone el autor del trabajo se aparta de las teorías propuestas por A. Tovar - M. Agud, Mahn y Van Eys, que partían del componente inicial esku, *esku erdi, *esku oker. A su juicio proviene, más bien, de la forma originaria ertz oker, “borde o extremo torcido”, a través de la evolución fonética ertz oker > *ertzoker > *ertzker > ezker, con significado de “borde torcido”
Narrating Trauma, Constructing Binaries: Partition in Muslim Women's Autobiographical Writings
No full textIn recent years, academic studies on the Partition of the Indian subcontinent in 1947 have shifted their emphasis from the grand narratives of high politics to the neglected experiences of individuals. To recover these personalised and often gendered pasts, oral testimonies have been employed alongside fiction, memoirs, diaries and newspaper accounts with an aim of understanding, not just the event of Partition, but also how it has been remembered and represented. In this process, the voices of Muslim women have continued to be underrepresented, often considered inaccessible to the Indian researchers who have pioneered the field on the basis that relevant historical subjects and sources are located primarily on the ‘other side’ of the border. Others highlight the cultural limitations connected to izzat and sharam, honour and shame, that have made it ‘taboo’ for Muslim women to divulge Partition stories that may include rape, abduction and forced conversion. As a necessary corrective, this chapter will focus on the theme of Partition in Muslim women’s autobiographical writing. These sources enable exploration of how Partition memories are constructed in relation to gender, class and community at different historical moments and locations. Chosen for close analysis is Jiban Khatar Pataguli (‘Pages From My Life’, 1991) by Bangladeshi educationalist and author, Jobeda Khanam (1920–1990). Of particular interest is her autobiography’s cathartic function for narrating trauma, but also the selective deployment of silences as a means of dealing with pain and complicity. Other major themes include the creation of binaries between self and other, assertions of victimhood and agency, and the role of rumour in remembrance
Claus - Enabling last-mile delivery in urban environments with limited mobility access
No full textIn this report the development and design of Claus is presented. Claus is an auxiliary drive train module for last-mile delivery hand trucks. The objective of the concept is to enable delivery workers to deliver parcels to the growing amount of addresses in urban environments with limited mobility access.Due to the combination of urbanization, the rising popularity of e-commerce and rising congestion levels in cities, delivery companies are increasingly struggling to transport their goods to the customer. Conventional delivery fleets, consisting of big delivery vans to handle the rising delivery volumes, are not suited to the urban environment anymore as cities are undergoing rising congestion rates and as automobiles are becoming a less prioritized mode of transport. Consequently, delivery workers have to cover larger distances from the van to the front door of the customer by foot. Usually, delivery workers use hand trucks to cover these last meters, but as these distances increase, walking the hand truck becomes a time consuming job.Claus is proposed as a solution for this last leg of parcel delivery. Claus is an auxiliary module with a built in electric drive train that connects to any regular hand truck. By connecting Claus to a hand truck, a four-wheel vehicle is created that can transport a the delivery worker along with his or her cargo. The hand truck acts as both the cargo carrier as well as the steering device, while Claus acts as a standing deck and a drive train. Thanks to Claus’ geometry and volume, Claus can be transported in a conventional delivery van similarly to the hand truck. By bringing both a hand truck and Claus during delivery shifts, delivery workers are enabled to quickly and easily cover areas that are becoming less accessible to delivery vans.Two prototypes were created that were used to validate the concept. A technical prototype acted as a means to validate the driving characteristics and the ergonomics. Furthermore, it was used to validate technical aspects such as the battery capacity and the drive train system. An aesthetic prototype was used to communicate the design to the stakeholders.Integrated Product Desig
Generalized Hyers–Ulam stability for general additive functional equations in quasi-β-normed spaces
No full textAbstractIn 1940 S.M. Ulam proposed the famous Ulam stability problem. In 1941 D.H. Hyers solved the well-known Ulam stability problem for additive mappings subject to the Hyers condition on approximately additive mappings. The first author of this paper investigated the Hyers–Ulam stability of Cauchy and Jensen type additive mappings. In this paper we generalize results obtained for Jensen type mappings and establish new theorems about the Hyers–Ulam stability for general additive functional equations in quasi-β-normed spaces
Möglichkeiten zur Bewertung des Zustandes von Straßenbauten (Bau und Rekonstruktion) unter Einbeziehung seismischer Messungen .
No full textCentral point of this study is to evaluate stiffness properties of pavement, specifically the E or G- modulus determined by different testing methods. Stiffness of soil is both stress and strain dependent property and otherwise different methods usually affect the material in different ways. The Young’s modulus E0 and shear modulus G0 correspond to the very small strain level are regarded as the initial or maximal stiffness of the relevant stress-strain curves of a given material. The modulus decay curve is called the degradation curve, which also reviewed in this study. With the results of different measurement methods applied for a reclaimed mining site in Klettwitz for determining of stiffness parameter of subsoil, author have tried to find a unification between the results considering the relationship between stiffness parameter and the range of strain levels. The testing methods executed at plant S9 in Klettwitz-Südfeld are: laboratory oedometer test, static plate load test, dynamic plate load test, and seismic testing methods (spectral analysis of surface wave, SASW). Some results getting from this study are: one receives different absolute values of stiffness parameter from different testing methods. The reason is different testing methods produce different range of strain levels in soil during their execution. Conventional and non-destructive testing methods should be combined together for investigating of subsoil characteristics. This means, the soil parameters must be adjusted to the current range of strain level. Especially for settlement calculation it is recommended that different values of stiffness modulus, Es, resulted by different testing methods should be simultaneously utilized along the depth beneath loading surface. Accuracy for determining of stiffness degradation curves depends a lot on the determination of maximal stiffness parameters (E0, G0) at the range of very small strain level, and it still requires much further studies
연성물질 표면 유체동력학에관한 연구
No full text학위논문(박사) - 한국과학기술원 : 물리학과, 2002.8, [ xii, 109 p. ]Soft matter materials show intermediate mechanical properties which include those of solid and liquid. Their interesting characteristics come from the flexibility of a long chain molecule or amphiphilic nature. These materials constitute our daily environment as well as the human body. This motivates diverse research and applications in petroleum industry, pharmacy, and bio-medical.
In this dissertation, the author adopts various soft matter materials and geometry and explores their surface hydrodynamic properties. At first, surface waves on semi-infinite viscoelastic medium were studied from the externally excited surface wave spectroscopy on agarose gels. He observed two coexisting elastic modes in the frequency region of crossover from elastic to capillary mode. The coexistence of two modes was explained based on the theory of elasticity. Moreover, differing from common solid, the viscous loss of soft matter materials enhances the two modes to be comparable. His second topic relates to more realistic cases: confined geometries. He measured surface waves propagating on thin gels with thicknesses less than 1 cm. In the frequency region where the elastic and surface tension forces dominate, multiple harmonics of a surface mode are predicted theoretically for a finite thickness due to a coupling with the normal direction wave to the surface. This result shows the first experimental measurement of the multiple harmonics of a surface mode. He compared the experimental data with the theoretical calculation. Finally, charged monolayers adsorbed by opposite charged macromolecules at an air-water interface were studied. He explored their structure-related thermodynamic and surface hydrodynamic properties. Using the enhanced damping of the capillary wave by energy dissipation due to the presence of an elastic monolayer, the cationic lipid-DNA complex formation could be sensitively observed.한국과학기술원 : 물리학과

Blaufuss, F. Halzen, C. Kopper (Changed to add one missing author, no other changes from initial version.)The recent observation by the IceCube neutrino observatory of an astrophysical flux of neutrinos represents the "first light" in the nascent field of neutrino astronomy. The observed diffuse neutrino flux seems to suggest a much larger level of hadronic activity in the non-thermal universe than previously thought and suggests a rich discovery potential for a larger neutrino observatory. This document presents a vision for an substantial expansion of the current IceCube detector, IceCube-Gen2, including the aim of instrumenting a volume of clear glacial ice at the South Pole to deliver substantial increases in the astrophysical neutrino sample for all flavors. A detector of this size would have a rich physics program with the goal to resolve the sources of these astrophysical neutrinos, discover GZK neutrinos, and be a leading observatory in future multi-messenger astronomy programs
U-SPECT-BioFluo: an integrated radionuclide, bioluminescence, and fluorescence imaging platform
No full textBackground: In vivo bioluminescence, fluorescence, and single-photon emission computed tomography (SPECT) imaging provide complementary information about biological processes. However, to date these signatures are evaluated separately on individual preclinical systems. In this paper, we introduce a fully integrated bioluminescence-fluorescence-SPECT platform. Next to an optimization in logistics and image fusion, this integration can help improve understanding of the optical imaging (OI) results. Methods: An OI module was developed for a preclinical SPECT system (U-SPECT, MILabs, Utrecht, the Netherlands). The applicability of the module for bioluminescence and fluorescence imaging was evaluated in both a phantom and in an in vivo setting using mice implanted with a 4 T1-luc + tumor. A combination of a fluorescent dye and radioactive moiety was used to directly relate the optical images of the module to the SPECT findings. Bioluminescence imaging (BLI) was compared to the localization of the fluorescence signal in the tumors. Results: Both the phantom and in vivo mouse studies showed that superficial fluorescence signals could be imaged accurately. The SPECT and bioluminescence images could be used to place the fluorescence findings in perspective, e.g. by showing tracer accumulation in non-target organs such as the liver and kidneys (SPECT) and giving a semi-quantitative read-out for tumor spread (bioluminescence). Conclusions: We developed a fully integrated multimodal platform that provides complementary registered imaging of bioluminescent, fluorescent, and SPECT signatures in a single scanning session with a single dose of anesthesia. In our view, integration of these modalities helps to improve data interpretation of optical findings in relation to radionuclide images.Version of Recor
