description: Four dimensional gravity with a U(1) gauge field, coupled to various fields in asymptotically anti-de Sitter spacetime, provides a rich arena for the holographic study of the strongly coupled (2+1)-dimensional dynamics of finite density matter charged under a global U(1). As a first step in furthering the study of the properties of fractionalized and partially fractionalized degrees of freedom in the strongly coupled theory, we construct electron star solutions at zero temperature in the presence of a background magnetic field. We work in Einstein-Maxwell-dilaton theory. In all cases we construct, the magnetic source is cloaked by an event horizon. A key ingredient of our solutions is our observation that starting with the standard Landau level structure for the density of states, the electron star limits reduce the charge density and energy density to that of the free fermion result. Using this result we construct three types of solution: One has a star in the infra-red with an electrically neutral horizon, another has a star that begins at an electrically charged event horizon, and another has the star begin a finite distance from an electrically charged horizon.

description: We study the significance of major-merger-driven star formation in the early Universe, by quantifying the contribution of this process to the total star formation budget in 80 massive (M* > 10^10 MSun) galaxies at z~2. Employing visually-classified morphologies from rest-frame V-band HST imaging, we find that 55+/-14% of the star formation budget is hosted by non-interacting late-types, with 27+/-8% in major mergers and 18+/-6% in spheroids. Given that a system undergoing a major merger continues to experience star formation driven by other processes at this epoch (e.g. cold accretion, minor mergers), ~27% is an upper limit to the major-merger contribution to star formation activity at this epoch. The ratio of the average specific star formation rate in major mergers to that in the non-interacting late-types is ~2.2:1, suggesting that the enhancement of star formation due to major merging is typically modest, and that just under half the star formation in systems experiencing major mergers is unrelated to the merger itself. Taking this into account, we estimate that the actual major-merger contribution to the star formation budget may be as low as ~15%. While our study does not preclude a major-merger-dominated era in the very early Universe, if the major-merger contribution to star formation does not evolve strongly into larger look-back times, then this process has a relatively insignificant role in driving stellar mass assembly over cosmic time.

description: We present a multi-wavelength study of the gravitational lens COSMOS J095930+023427 (z=0.89), together with the associated galaxy group located at $z\sim0.7$ along the line of sight and the lensed background galaxy. The source redshift is currently unknown, but estimated to be at $z_s \sim 2$. The analysis is based on the available public HST, Subaru, Chandra imaging data, and VLT spectroscopy. The lensing system is an early-type galaxy showing a strong [OII] emission line, and produces 4 bright images of the distant background source. It has an Einstein radius of 0.79", about 4 times large than the effective radius. We perform a lensing analysis using both a Singular Isothermal Ellipsoid (SIE) and a Peudo-Isothermal Elliptical Mass Distribution (PIEMD) for the lensing galaxy, and find that the final results on the total mass, the dark matter (DM) fraction within the Einstein radius and the external shear due to a foreground galaxy group are robust with respect of the choice of the parametric model and the source redshift (yet unknown). We measure the luminous mass from the photometric data, and find the DM fraction within the Einstein radius $f_{\rm DM}$ to be between $0.71\pm 0.13$ and $0.79 \pm 0.15$, depending on the unknown source redshift. Meanwhile, the non-null external shear found in our lensing models supports the presence and structure of a galaxy group at $z\sim0.7$, and an independent measurement of the 0.5-2 keV X-ray luminosity within 20" around the X-ray centroid provides a group mass of $M=(3-10)\times 10^{13}$ M$_{\odot}$, in good agreement with the previous estimate derived through weak lensing analysis.

description: Mobile Ad-hoc Networks (MANETS) consists of a collection of mobile nodes without having a central coordination. In MANET, node mobility and dynamic topology play an important role in the performance. MANET provide a solution for network connection at anywhere and at any time. The major features of MANET are quick set up, self organization and self maintenance. Routing is a major challenge in MANET due to it's dynamic topology and high mobility. Several routing algorithms have been developed for routing. This paper studies the AODV protocol and how AODV is performed under multiple connections in the network. Several issues have been identified. The bandwidth is recognized as the prominent factor reducing the performance of the network. This paper gives an improvement of normal AODV for simultaneous multiple connections under the consideration of bandwidth of node.

description: We explore the properties of spin splitting for neutral particles possessing electric and magnetic dipole moments propagating in an electromagnetic field. Two notable features of the spin splitting and the associated Larmor precession are found, which are consequences of special relativity. First, we report the existence of an upper limit of spin splitting equal to twice the rest energy of the particle, and a corresponding upper limit for the Larmor precession frequency. Second, we predict the noninvariance of the spin splitting and the corresponding Larmor frequency with respect to Lorentz boosts, which bears resemblance to the classical Doppler effect.

description: We analyze the dynamic operation of an optical modulator based on double graphene-layer(GL) structure utilizing the variation of the GL absorption due to the electrically controlled Pauli blocking effect. The developed device model yields the dependences of the modulation depth on the control voltage and the modulation frequency. The excitation of plasma oscillations in double-GL structure can result in the resonant increase of the modulation depth, when the modulation frequency approaches the plasma frequency, which corresponds to the terahertz frequency for the typical parameter values.

description: The neutrino annihilation is one of the most promising candidates for the jet production process of gamma-ray bursts. Although neutrino interaction rates depend strongly on the neutrino spectrum, the estimations of annihilation rate have been done with an assumption of the neutrino thermal spectrum based on the presence of the neutrinospheres, in which neutrinos and matter couple strongly. We consider the spectral change of neutrinos caused by the scattering by infalling materials and amplification of the annihilation rate. We solve the kinetic equation of neutrinos in spherically symmetric background flow and find that neutrinos are successfully accelerated and partly form nonthermal spectrum. We find that the accelerated neutrinos can significantly enhance the annihilation rate by a factor of $\sim 10$, depending on the injection optical depth.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Motivated by recent progress of theory and experiment on the anomalous magnetic moment of the electron, a_e, we update the hadronic contributions to a_e. Using our up-to-date compilation of e^+ e^- \to hadrons data, we find the leading order hadronic contribution a_e^{had,LO,VP} = (1.866 \pm 0.010_{exp} \pm 0.005_{rad}) \cdot 10^{-12} and the next-to-leading order hadronic contribution a_e^{had,NLO,VP} = (- 0.2234 \pm 0.0012_{exp} \pm 0.0007_{rad}) \cdot 10^{-12}, where the first and second errors are from the error of the experimental data and the uncertainty in the treatment of radiative corrections, respectively. These values are compatible with earlier evaluations by other groups, but have significantly improved uncertainties due to the more precise input data used. We also update the leading order hadronic contribution to the ground state hyperfine splitting of muonium, obtaining Δν_{Mu}^{had,VP} = (232.68 \pm 1.25_{exp} \pm 0.72_{rad}) Hz. This value is consistent with the most precise evaluation in the literature and reduces its error by a factor of two.

description: Ancient DNA has revealed multiple episodes of admixture in human prehistory during geographic expansions associated with cultural innovations. One important example is the expansion of Neolithic agricultural groups out of the Near East into Europe and their consequent admixture with Mesolithic hunter-gatherers.1,2,3,4 Ancient genomes from this period provide an opportunity to study the role of admixture in providing new genetic variation for selection to act upon, and also to identify genomic regions that resisted hunter-gatherer introgression and may thus have contributed to agricultural adaptations. We used genome-wide DNA from 677 individuals spanning Mesolithic and Neolithic Europe to infer ancestry deviations in the genomes of admixed individuals and to test for natural selection after admixture by testing for deviations from a genome-wide null distribution. We find that the region around the pigmentation-associated gene SLC24A5 shows the greatest overrepresentation of Neolithic local ancestry in the genome (|Z| = 3.46). In contrast, we find the greatest overrepresentation of Mesolithic ancestry across the major histocompatibility complex (MHC; |Z| = 4.21), a major immunity locus, which also shows allele frequency deviations indicative of selection following admixture (p = 1 × 10-56). This could reflect negative frequency-dependent selection on MHC alleles common in Neolithic populations or that Mesolithic alleles were positively selected for and facilitated adaptation in Neolithic populations to pathogens or other environmental factors. Our study extends previous results that highlight immune function and pigmentation as targets of adaptation in more recent populations to selection processes in the Stone Age.

description: This is an excel calculator for the DEMQOL, DEMQOL-Proxy and DEMQOL-CH to allow interested parties to use the instruments without the need for specialist software (e.g. SPSS).
Open the calculator for instructions on how to use it.

DEMQOL is a patient reported outcome measure (PROM) which is designed to enable the assessment health-related quality of life of people with dementia.
It was developed according to best quality psychometric principles by a multidisciplinary team including BSMS, KCL, the London School of Hygiene and Tropical Medicine, the London School of Economics and Nottingham and Sheffield Universities. DEMQOL is designed to work across dementia subtypes and care arrangements and can be used at all stages of dementia.

The measure consists of two questionnaires.1) DEMQOL is a 28 item interviewer-administered questionnaire answered by the person with dementia.2) DEMQOL-Proxy is a 31 item interviewer-administered questionnaire answered by a caregiver.
In the majority of studies, DEMQOL and DEMQOL-Proxy are used together.

Since its original development, the DEMQOL-CH has been adapted from the DEMQOL-Proxy for use within care homes to be completed by care home staff without interview. The DEMQOL-CH has the same items as the DEMQOL-Proxy, but the questionnaire formating has been adapted.

description: We present spectroscopic observations of ultra compact dwarf (UCD) galaxies in the Fornax and Virgo Clusters made to measure and compare their stellar populations. The spectra were obtained on the Gemini-North (Virgo) and Gemini-South (Fornax) Telescopes using the respective Gemini Multi-Object Spectrographs. We estimated the ages, metallicities and abundances of the objects from mea- surements of Lick line-strength indices in the spectra; we also estimated the ages and metallicities independently using a direct spectral fitting technique. Both methods re- vealed that the UCDs are old (mean age 10.8 \pm 0.7 Gyr) and (generally) metal-rich (mean [Fe/H] = -0.8 \pm 0.1). The alpha-element abundances of the objects measured from the Lick indices are super-Solar. We used these measurements to test the hypothesis that UCDs are formed by the tidal disruption of present-day nucleated dwarf elliptical galaxies. The data are not consistent with this hypothesis because both the ages and abundances are significantly higher than those of observed dwarf galaxy nuclei (this does not exclude disruption of an earlier generation of dwarf galaxies). They are more consistent with the properties of globular star clusters, although at higher mean metallicity. The UCDs display a very wide range of metallicity (-1.7

description: We present results of the first extensive and deep CCD photometric survey carried out in the field of the open cluster Trumpler 27, an object in the constellation of Sagittarius not far from the Galaxy center. We look for young stars clumps that might plausibly be associated with spiral structure. Wide-field UBVI photometry combined with infrared information allows us to reconstruct the distribution in reddening and distance of young stars in the field using the Color-Color and Color-Magnitude diagrams. The analysis of our data, combined too with extensive spectroscopy taken from literature shows that the real entity of Trumpler 27 as an open cluster is far from being firmly stated. In fact, instead of finding a relatively compact group of stars confined to a small distance range, we found that stars associated to Trumpler 27 are, indeed, a superposition of early type stars seen along the line of sight extending over several kiloparsecs beyond even the center of the galaxy. We demonstrate that at each distance range it becomes possible to generate a color-magnitude diagram resembling that of an open cluster. This way, our analysis indicates that what was considered an open cluster characterized by a significant age spread is a stellar continuum that reaches its maximum number of stars at approximately 3.5 kpc from the Sun, the distance of the Scutum-Crux arm approximately. At the same time, and after analyzing the way early type stars distribute with distance, we found some of these stellar groups may be linked, within the distance errors, with other inner spiral arms of our galaxy, including the Near 3 kpc arm at approximately 5 kpc from the Sun. However, very young stars by themselves do not seem to trace strongly the inner spiral arms since they are distributed evenly across several kiloparsecs toward the center of the Galaxy.

description: We present the first results of an analysis of the properties of the molecular gas in the nuclear regions (r < 300 pc) of a sample of six nearby galaxies, based on new high spatial resolution observations obtained in the K-band with the near-infrared integral field spectrograph SINFONI at the Very Large Telescope. We derive two-dimensional distributions of the warm molecular and ionized gas from the H2, Br_gamma and HeI emission lines present in the spectra of the galaxies. We find a range of morphologies, including bar- and ring-like distributions and either centrally peaked or off-centre emission. The morphologies of the molecular and the ionized gas are not necessarily coincident. The observed emission-line ratios point towards thermal processes as the principal mechanism responsible for the H2 excitation in the nuclear and circumnuclear regions of the galaxies, independently of the presence of an active nucleus. We find that a rescaling of the H2 2.12 microns emission-line luminosity by a factor beta~1200 gives a good estimate (within a factor of 2) of the total (cold) molecular gas mass. The galaxies of the sample contain large quantities of molecular gas in their centres, with total masses in the ~ 105 - 108 Msol range. Never the less, these masses correspond to less than 3 per cent of the stellar masses derived for the galaxies in these regions, indicating that the presence of gas should not affect black hole mass estimates based on the dynamical modelling of the stars. The high-spatial resolution provided by the SINFONI data allowed us to resolve a circumnuclear ring (with a radius of ~270 pc) in the galaxy NGC 4536. The measured values of the Br_gamma equivalent width and the HeI/Br_gamma emission-line ratio suggests that bursts of star formation occurred throughout this ring as recently as 6.5 Myr ago.

description:
Geomorphic mapping based on high-resolution lidar data indicates that the Van Zandt Landslide Complex (VZLC) has multiple crosscutting debris lobes (up to 51.4 x 106 m3) with long runouts (H/L= 0.14; 0.21) typical of catastrophic rock avalanches. AMS 14C dates from in situ logs and lake sediment cores yield overlapping ages for emplacement of Debris Lobe 2 (1330-1285 cal. yrs. B.P) and Debris Lobe 3 (1300-1285 cal. yrs. B.P.) Although Debris Lobe 3 overlies a portion of Debris Lobe 2, it is possible that emplacement of the two deposits was nearly synchronous or in rapid succession. The debris lobes are not contemporaneous with any known paleoseismic events from local shallow-crustal faults but do overlap with a known Cascadia megaquake (event T4). Abundant transverse surface fractures, a distal “splash zone,” as well as debris exposures showing basal mixing, soft-sediment deformation, and substrate injection features provide evidence for significant rock avalanche-substrate interaction and mobility-enhancing liquefaction. To evaluate ongoing retrogressive block sliding in the headwall region, we installed wire extensometers in three prominent tension gaps and tracked their movement over an 18-month period between 10/15 and 4/17; all three sites experienced measurable displacement (up to 5.7 cm total), with progressive movement largely accelerating and decelerating in response to short- and long-term precipitation conditions. Although recorded strain rates were relatively slow during this period, incipient detachment scarps across the headwall involve slabs with a total volume of ~35.2 x 106 m3, the potential release of which could pose a serious hazard to people and property in the valley below.
title: The Stratigraphy and Geochemistry of the Crescent Formation Basalts and the Bedrock Geology of Associated Igneous Rocks Near Bremerton, Washington
Creators: name: Clark, Kenneth P.

description:
A stratigraphic section developed for the Bremerton rocks in the Kitsap Peninsula suggests formation by rifting in a marine environment. Basal gabbro, dated by 40Ar/39Ar at 49.8 Ma plus or minus 0.8 Ma, and associated mafic to felsic plutonics, appear to be the source of a mafic dike complex that composes 100% of the stratigraphic level above the plutonics. These dikes are the apparent feeders to overlying submarine and subaerial volcanics. The previously unrecognized submarine sequence consists of interbedded basaltic breccia, tuffs, basalt flows, and basaltic sandstone, siltstone, and conglomerate. Approximately 1 km of columnar basalt flows cap the sequence.

Structures in the Bremerton rocks suggest that as many as four deformations may have affected these rocks. In the middle Eocene, extension to the north or northwest caused rifting and emplacement of the mafic dikes and lavas; several faults show that this extension was joined or followed by northeast-directed compression. Small faults and shears may have formed later by compression to the northwest. Reactivation of one of these faults and emplacement of northwest-striking Cascade arc(?) dikes suggest the latest deformation was extension to the northeast.

The gabbro and basalts have chemistry transitional between N-type MORB and enriched ocean island basalt. Large-ion-lithophile to high-field-strength trace element ratios are similar to those of back-arc basin basalt. Felsic plutonics are enriched in elements (especially Zr) indicative of an arc influence. Several dikes intruding the gabbro are chemically indistinguishable from P-type (plume) ocean island basalt.

Stratigraphic sections were developed in the basalts of the Crescent Formation and for basalts near Port Townsend in the Olympic Peninsula. Comparison to the subaerial basalts near Bremerton shows that the latter are quite similar to the upper subaerial Crescent Formation basalts and Port Townsend basalts. New chemical data for 16 flows of the Olympic Peninsula basalts are also similar to that of the Bremerton rocks.

Stratigraphic and chemical similarities imply that rocks of all three areas are coeval. Deposition of the Crescent Formation basalts on a continentally-derived fan, stratigraphic and structural characteristics of the Bremerton rocks, and geochemical data on rocks of ail three areas suggest that these rocks formed by rifting of the western margin of the North America continent. Following rifting and basalt generation, the rocks may have moved north due to oblique convergence of the oceanic and continental plates, where they were thrust under Vancouver Island along the Leech River Fault. Thrusting moved outboard of the basalts and underlying fan; continued convergence thrust marine sediments that make up the Olympic core rocks beneath the basalts and underlying fan.

title: A Paleomagnetic Paleolatitude Determination from the Upper Cretaceous Units of the Gold Beach Terrane, Southwest Coastal Oregon
Creators: name: Liner, Noel
Publisher: name: Western Washington University
Year: 2005

description:
The paleolatitude for the Gold Beach terrane has been under debate from several sources (Bourgeois, 1980b; Bourgeois, 1985; Jayko and Blake, 1985; Seiders and Blome, 1987; Aalto, 1989) since the 1980 publication of Joanne Bourgeois’ PhD thesis connecting the Upper Cretaceous formations of the Gold Beach terrane to the Nacimiento Block, currently in the vicinity of Southern California; During the Cretaceous, the Nacimiento Block was farther south than its present position by about 200 km (Blake and Jayko, 1985). The opposing hypothesis of Seiders and Blome (1987) connects the Gold Beach terrane to the neighboring Klamath block, implying at most 300 km of northwards transport for the Gold Beach terrane (Seiders and Blome, 1987). Paleomagnetic study of the Upper Cretaceous units of the Gold Beach terrane has determined that the units originated south of their present position by 1550 +/- 500 km, at a latitude of 34° during the Campanian, placing the origin of the Upper Cretaceous units at the Cretaceous latitude of northern Baja, Mexico. A compaction correction was applied using the results of AMS-determined rock magnetic fabric, showing a small amount of post-Cretaceous inclination shallowing. After correction for tectonic rotation, AMS fabric implies an eastward derived sediment source, possibly from the Nacimiento Block. These results substantiate the hypothesis of Bourgeois (1980), Blake and Jayko (1985) for a southerly latitude of origin of the Gold Beach terrane and rule out the hypothesis of Seiders and Blome (1987) for a local origin connected to the Klamath block. The units are overlain by the Mio-Pliocene Empire Formation at Blacklock Point, however several neighboring late Cretaceous terranes are overlain by the mid- Eocene Lookingglass Formation, capping the emplacement age of the Gold Beach terrane to about 50 Ma. The displacement estimated by this study compares favorably to plate motion rates derived by Engebretson et al., (1984) for translation of this terrane on the Kula plate to its present position by 50 Ma.

description: A photometric UBV survey is presented for 610 stars in a region surrounding the Cepheid AQ Puppis and centered southwest of the variable, based upon photoelectric measures for 14 stars and calibrated iris photometry of photographic plates of the field for 596 stars. An analysis of reddening and distance for program stars indicates that the major dust complex in this direction is ~1.8 kpc distant, producing differential extinction described by a ratio of total-to-selective extinction of R=Av/E(B-V)=3.10+-0.20. Zero-age main-sequence fitting for the main group of B-type stars along the line of sight yields a distance of 3.21+-0.19 kpc (Vo-Mv=12.53+-0.13 s.e.). The 29.97d Cepheid AQ Pup, of field reddening E(B-V)=0.47+-0.07 (E(B-V)(B0)=0.51+-0.07), appears to be associated with B-type stars lying within 5' of it as well as with a sparse group of stars, designated Turner 14, centered south of it at J2000.0 = 07:58:37, -29:25:00, with a mean reddening of E(B-V)=0.81+-0.01. AQ Pup has an inferred luminosity as a cluster member of =-5.40+-0.25 and an evolutionary age of 3x10^7 yr. Its observed rate of period increase of 300.1+-1.2 s/yr is an order of magnitude larger than what is observed for Cepheids of comparable period in the third crossing of the instability strip, and may be indicative of a high rate of mass loss or a putative fifth crossing. Another sparse cluster, designated Turner 13, surrounds the newly-recognized 2.59d Cepheid V620 Pup, of space reddening E(B-V)=0.64+-0.02 (E(B-V)(B0)=0.68+-0.02), distance 2.88+-0.11 kpc (Vo-Mv=12.30+-0.08 s.e.), evolutionary age 10^8 yr, and an inferred luminosity as a likely cluster member of =-2.74+-0.11. V620 Pup is tentatively identified as a first crosser, pending additional observations.

title: The Stones They Chose: Lithic Analysis and Design Selections at Čḯxwicən Village (45CA523)
Creators: name: Sparaga, Joseph
Publisher: name: Western Washington University

description:
This thesis used a Design Theory approach to analyze lithic artifacts from the Čḯxwicən village site, particularly to understand the distinctions between utilitarian and prestige values in the production of lithic tools and their intended role within the society. The Northwest Coast has a variety of resources available; how groups utilized these resources for functional and social purposes is important in understanding behavior choices. The Čḯxwicən village site was a large permanent settlement originally inhabited by the ancestors of the Lower Elwha Klallam Tribe between 2,000 years BP to the historical contact period. The site was rediscovered near Port Angeles, where excavations exposed a number of house structures and associated exterior activity areas.

This thesis addresses the tools associated with one of the house structures and several exterior areas. The qualities of the materials is important in understanding their value in a society: whether the material has a utilitarian or social value. Design Theory is a suitable method for analyzing artifacts and the materials they are manufactured from to determine these different values. This thesis aims to analyze the lithic artifacts from Block A4 to distinguish between their functional, esteem, and prestige values.

My research analyzed 1,515 stone artifacts recovered from Block A4 from the 39,505 total artifacts from Quadrant A. I identified three specific tool industries at Čḯxwicən village: the production of quartz crystal tools, cortex spall tools, and incised stones. A number of other materials and tools were present at the site, using a combination of reduction manufacturing techniques. Most artifacts had a single material dominating their manufacture, however outliers and variabilities made the design choices of the manufacturers clearer.

The results indicated that the majority of artifacts recovered were utilitarian in nature and manufactured expediently. Only a small number of tools required much extensive investment time. Debitage and cortex spall tools dominated the assemblage. Tools intended to manufacture other objects, such as gravers and abraders, were also present and important for creating incised stones and fishhook shanks, as well as modifying organic materials such as bone and shell. A small number of adzes and edged tools from unique materials were identified: these can be considered investment tools or objects. From the analysis, I determined that a new classification of artifact is need: Investment Tools. These objects have the qualities of a prestige good, being of rare material or requiring significant time investment, as well as fulfilling utilitarian needs, that the combination of material and function are too advantageous not to be functional.

description: As práticas atualmente recomendadas em Intervenção Precoce na Infância (IPI) refletem o avanço da investigação, quer neste campo específico, quer no campo do desenvolvimento das crianças. O crescente enfoque em práticas centradas na família, nas rotinas/atividades diárias e na funcionalidade implica uma transformação na forma de os profissionais de IPI facultarem os seus serviços, nomeadamente, a passagem de um serviço direto (i.e., de um para um) com a criança para um trabalho colaborativo com os adultos significativos para a criança. Esta transformação não constitui uma tarefa simples, quer quando o interlocutor é a família, quer quando se trata do(a) educador(a) de infância. Partindo do conhecimento disponível atualmente, das práticas recomendadas e da nossa legislação, este trabalho tem como objetivo apresentar um modelo de articulação entre os profissionais de IPI e os(as) educadores(as) de infância, a trabalharem em creches e em jardins de infância. O modelo apresentado tem por base oito passos do processo de Consultoria Colaborativa (Buysse & Wesley, 2005), operacionalizados através das práticas do modelo de Intervenção Precoce Baseada nas Rotinas (McWilliam, 2010).

description: In this paper, we study the spectrum usage efficiency by applying wideband methods and systems to the existing analog systems and applications. The essential motivation of this work is to define the prospective coexistence between analog FM and digital Spread Spectrum systems in an efficient way sharing the same frequency band. The potential overlaid Spread Spectrum (SS) system can spectrally coincide within the existing narrowband Frequency Modulated (FM) broadcasting system upon several limitations, originating a key motivation for the use of the FM radio frequency band in many applications, encompassing wireless personal and sensors networks. The performance of the SS system due to the overlaying analog FM system, consisting of multiple narrowband FM stations, is investigated in order to derive the relevant bit error probability and maximum achievable data rates. The SS system uses direct sequence (DS) spreading, through maximal length pseudorandom sequences with long spreading codes. The SS signal is evaluated throughout theoretical and simulation-based performance analysis, for various types of spreading scenarios, for different carrier frequency offset (Δf) and signal-to-interference ratios, in order to derive valuable results for future developing and planning of an overlay scenario.
