Drawing on a recent ethnographic research project conducted in an urban neighbourhood of Liverpool, England, this paper focuses on Somali speakers, relating the experience of members of this minority language community to the local linguistic and cultural ecology of the city. The community forms part of a Somali diaspora created largely as a consequence of civil war in Somalia towards the end of the twentieth century. The paper opens with an account of the context of the languages and cultures of Liverpool, going on to explore the communicative roles of languages and literacies — Somali, English and Arabic — in the lives of members of the Somali community. Also reported are insights, gained in interviews, into the symbolic values which these languages and literacies hold for them. These data indicate unresolved tensions felt by the interviewees in relation to issues both of cultural identity and of social and educational aspirations — tensions which are closely linked to widespread concern in the community over what is perceived as inter-generational language shift, from Somali to English. This concern has led to the setting up of Somali literacy teaching for young people in the community, and the study included observation of these classes. The paper considers the contribution of such affirmative action to the maintenance and valorisation of Somali, as the language of community heritage, before concluding with discussion of the implications of the Somali community experience in Liverpool — of both marginalisation and resistance — for the management of multilingualism in this modern city. Sommaire Les langues dans la marge: Le cas du somalien à Liverpool Cet article se concentre sur les locuteurs somaliens. Les informations obtenues se rapportent à l’expérience des membres de cette communauté linguistique minoritaire et s’inspirent des conclusions d’une étude ethnographique menée dans un quartier urbain de Liverpool, en Angleterre. La communauté fait partie de la diaspora somalienne, créée principalement à la suite de la guerre civile en Somalie vers la fin du 20ème siècle. L’article présente le contexte des langues et cultures de Liverpool ainsi que les rôles de communication des langues et des taux d’alphabétisation pour les langues — somalien, anglais, arabe — dans la vie des membres de la communauté somalienne. En s’appuyant sur des entretiens effectués, cet article donne aussi un aperçu des valeurs symboliques que représentent pour eux ces langues et leur taux d’alphabétisation. Ces données révèlent les tensions irrésolues ressenties par les personnes interviewées en ce qui concerne les questions à la fois de culture identitaire et d’aspirations sociales et en matière d’éducation. Ces tensions sont intimement liées à une inquiétude répandue parmi la communauté en ce qui concerne les changements qui semblent intervenir au niveau du somalien et de l’anglais entre les générations. Cette inquiétude a mené à la création d’un enseignement du somalien pour les jeunes de la communauté et cette étude inclus les observations de ces classes. L’article prend en considération la contribution d’une action si affirmative pour le maintien et la valorisation du somalien, en qualité de langue du patrimoine de la communauté, et termine en conclusion par une discussion des implications — à la fois de la marginalisation et de la résistance de la communauté somalienne à Liverpool — en ce qui concerne la gestion du multilinguisme de cette ville moderne.

La komunumo formas parton de somalia diasporo kreita plejparte rezulte de la civila milito en Somalio fine de la dudeka jarcento. La artikolo komenciĝas per prezento de la lingva kaj kultura kunteksto de Liverpool, kaj poste esploras la komunikajn rolojn de lingvoj kaj leg- kaj skribkapabloj — somaliaj, anglaj kaj arabaj — en la vivoj de anoj de la somalia komunumo. Oni ankaŭ raportas pri perceptoj, gajnitaj el intervjuoj, pri ilia sento de la simbolaj valoroj entenataj en tiuj lingvoj kaj kapabloj. Tiuj datenoj indikas, ke la intervjuatoj sentis nesolvitajn streĉitecojn rilate demandojn kaj de kultura identeco kaj de sociaj kaj edukaj aspiroj — streĉitecojn proksime ligitajn al disvastiĝinta maltrankvilo en la komunumo pri tio, kion oni perceptas kiel intergeneracian lingvoŝoviĝon de la somalia al la angla. Tiu maltrankvilo kondukis al starigo de somalia alfabetiga instruado por komunumaj gejunuloj, kaj la studo enhavis ankaŭ observadon de tiuj klasoj. La artikolo konsideras la kontribuon de tia pozitiva agado al konservado kaj valorigo de la somalia, kiel la lingvo de la komuna heredaĵo. La artikolo finiĝas per diskuto de la implicoj de la spertoj de la somalia komunumo en Liverpool — spertoj kaj de marĝenigo kaj de rezistado — por la mastrumado de multlingvismo en tiu moderna urbo. [La studo baziĝas sur esploroj subtenataj en 2001–2 de Leverhulme Trust. La aŭtoro danke rekonas la helpon de Cabdillaahi Cawed Cige, Mariam Salah kaj Samsam Saleh.]

In the proposed paper, a flexible Yagi Dipole Antenna based on PET Substrate is designed for the RF system-on-package (RF SOP) applications. RF antenna as a smart sensor is designed on a Flexible substrate Polyethylene Terephtalate (PET). It is the more popular and universally accepted thermoplastic polymer belonging to the family of the polyester. It is generally employed in textiles, thermoforming packaging along with glass fibers. In the proposed design Coplanar Strip line (CPS) is used as a feeder and the RF antenna is a Yagi dipole Antenna with a single driven element i.e. director, and a single reflecting element i.e. reflector. It is a linearly polarized antenna which means it radiates in a single direction. The antenna is designed at a resonating frequency of 5 GHz with a return loss of -23 dB. Simulations of the flexible PET based Yagi Dipole Antenna is carried out by using CST Studio Suite software for Return loss, Radiation plot with varied curvatures. The results for designed flexible Yagi Dipole Antenna imprinted with a PET substrate for portable wireless electronics are analyzed.

AbstractThe blood–brain barrier (BBB) opening induced by electromagnetic pulses (EMPs) may be a drug delivery strategy of central nervous system (CNS) diseases. However, the mechanism of EMP-induced BBB opening is still ambiguous. Previous studies have shown the relation between the external field and the extent of BBB permeation (referred to as the effect), while the connection between the internal field and the effect remains unknown. Here, the influence of individual differences on the field distribution in the human brain with EMPs is investigated, the dielectric parameters of the specific anthropomorphic mannequin (SAM) and structural parameters of the spherical brain are adjusted, and the field distribution in the brain illuminated by EMPs at the frequency range of 0–0.5 GHz is simulated based on the Computer Simulation Technology (CST) Studio Suite. The results show that the average electric field in the brain is about 1/100–1/5 of the incident field within the studied frequency range, individual differences have little effect on the field distribution in the human brain; and thus, it is reliable to establish the connection between the internal field and the effect, which is of great theoretical significance for further study of the mechanism of an EMP on the brain.

This thesis deals with brief research on problematics of antennas in microwave band for omni-directional applications, own design and assembling of such an antenna. The purpose of the design is to have a best possible radiation patterns and reflection loss of our antenna. Conical monopole is chosen and it is simulated and changed to get the best possible parameters. Two prototypes are manufactured with mechanical changes applied and their parameters measured. Finished antenna is used for experimental channel measurement.

When designing military vehicles, it is of interest to make the vehicles difficult to detect using radar. The radar cross-section (RCS) property indicates how easily a vehicle is detected by radar and should thus be minimized. However, the RCS of a vehicle represents the cross-sectional area of a perfectly reflecting sphere that would produce the same reflection strength as the vehicle in question. Since this is extremely complicated to calculate as military vehicles are quite complex, these calculations are performed using computational simulations. BAE Systems Hägglunds is looking into changing from their current simulation software OPTISCAT to CST Studio Suite and thus want to know how CST performs and compares against OPTISCAT. In this work, we show that CST obtains results within 2% of theoretical data when simulating a sphere and a slab. When simulating vehicles, the RCS difference between the two software is from 3% to 55% while showing similar general behavior. Results indicate that CST performs well when simulating simple objects but deviates from OPTISCAT when simulating the vehicle. It is not surprising that the software does not match up perfectly since they use different theoretical approaches, OPTISCAT uses physical optics while CST an extension to physical optics called the Shooting Bouncing Ray method. Even though the software differs to this extent it is most likely possible that CST can be a suitable replacement for OPTISCAT. When looking at RCS the important part is the location of spikes and since they have similar general behavior, those spikes may still be possible to identify. This thesis will hopefully act as a starting point for further examination of CST as a software for simulating RCS, for example by comparing results from CST to experimentally measured data. Hopefully it will also be used to improve the design process of making military vehicles harder to detect.
