description: Laser-driven rescattering of electrons is the basis of many strong-field phenomena in atoms and molecules. Here, we will show how this mechanism operates in extended atomic systems, giving rise to effective energy absorption. Rescattering from extended systems can also lead to energy loss, which in its extreme form results in non-linear photo-association. Intense-laser interaction with atomic clusters is discussed as an example. We explain fast electron emission, seen in experimental and numerically obtained spectra, by rescattering of electrons at the highly charged cluster.

description: Obstructive Sleep Apnea (OSA) is a highly prevalent but inconspicuous disease that seriously jeopardizes the health of human beings. Polysomnography (PSG), the gold standard of detecting OSA, requires multiple specialized sensors for signal collection, hence patients have to physically visit hospitals and bear the costly treatment for a single detection. Recently, many single-sensor alternatives have been proposed to improve the cost efficiency and convenience. Among these methods, solutions based on RR-interval (i.e., the interval between two consecutive pulses) signals reach a satisfactory balance among comfort, portability and detection accuracy. In this paper, we advance RR-interval based OSA detection by considering its real-world practicality from energy perspectives. As photoplethysmogram (PPG) pulse sensors are commonly equipped on smart wrist-worn wearable devices (e.g., smart watches and wristbands), the energy efficiency of the detection model is crucial to fully support an overnight observation on patients. This creates challenges as the PPG sensors are unable to keep collecting continuous signals due to the limited battery capacity on smart wrist-worn devices. Therefore, we propose a novel Frequency Extraction Network (FENet), which can extract features from different frequency bands of the input RR-interval signals and generate continuous detection results with downsampled, discontinuous RR-interval signals. With the help of the one-to-multiple structure, FENet requires only one-third of the operation time of the PPG sensor, thus sharply cutting down the energy consumption and enabling overnight diagnosis. Experimental results on real OSA datasets reveal the state-of-the-art performance of FENet.

description: We calculate strange star properties, using large N_c approximation with built-in chiral symmetry restoration (CSM). We used a relativistic Hartree Fock mean field approximation method, using a modified Richardson potential with two scale parameters Λand Λ^\prime, to find a new set of equation of states for strange quark matter. We take the effect of temperature (T) on gluon mass, in addition to the usual density dependence, and find that the transition T from hadronic matter to strange matter is 80 MeV. Therefore formation of strange stars may be the only signal for formation of QGP with asymptotic freedom and CSM.

Finally, we discuss the role of the mass spectrum in population studies of young cooling NSs. We formulate a kind of {\it mass constraint} which can be helpful, in our opinion, in discussing different competive models of the thermal evolution of NSs.

description: In this paper, we present a novel general framework grounded in the factor graph theory to solve kinematic and dynamic problems for multi-body systems. Although the motion of multi-body systems is considered to be a well-studied problem and various methods have been proposed for its solution, a unified approach providing an intuitive interpretation is still pursued. We describe how to build factor graphs to model and simulate multibody systems using both, independent and dependent coordinates. Then, batch optimization or a fixed-lag-smoother can be applied to solve the underlying optimization problem that results in a highly-sparse nonlinear minimization problem. The proposed framework has been tested in extensive simulations and validated against a commercial multibody software. We release a reference implementation as an open-source C++ library, based on the GTSAM framework, a well-known estimation library. Simulations of forward and inverse dynamics are presented, showing comparable accuracy with classical approaches. The proposed factor graph-based framework has the potential to be integrated into applications related with motion estimation and parameter identification of complex mechanical systems, ranging from mechanisms to vehicles, or robot manipulators.

description: Recently, Simon Plouffe has discovered a number of identities for the Riemann zeta function at odd integer values. These identities are obtained numerically and are inspired by a prototypical series for Apery's constant given by Ramanujan: $ζ(3)=\frac{7π^3}{180}-2\sum_{n=1}^\infty\frac{1}{n^3(e^{2πn}-1)}$ Such sums follow from a general relation given by Ramanujan, which is rediscovered and proved here using complex analytic techniques. The general relation is used to derive many of Plouffe's identities as corollaries. The resemblance of the general relation to the structure of theta functions and modular forms is briefly sketched.

Investigation of the transcription activating properties of Spo0A from Bacillus subtilis
Creators: name: Bird, Terry H.
Publisher: name: University of British Columbia
Year: 2009

description: SpoOA is a key regulator of sporulation in Bacillus subtilis. Genetic investigations have indicated that SpoOA activates or represses transcription of various loci which ultimately commit the cell to spore development under poor nutrient conditions. The transcription regulating properties of SpoOA are believed to be controlled by protein phosphorylation through a signal transduction system termed a ‘phosphorelay’. The spoIL4 and spoliG operons are two targets for activation by SpoOA-P that are essential to the induction of a sporulation response because each encodes a sporulation specific sigma factor. An in vitro transcription assay was used to examine the effect of SpoOA and its phosphorylation on transcription initiation at the spollA and spoliG promoters (P[sub spoIlA] and P[sub spoIIG]). Phosphorylation of SpoOA dramatically enhanced its ability to stimulate the level of transcription initiation at both promoters. A kinetic analysis of the initiation process at P[sub spoIIG] demonstrated that the rate of initiation was independent of the concentration of RNA polymerase and promoter template. In contrast, increased concentrations of SpoOA-P accelerated the initiation reaction at P[sub spollG] by affecting a rate limiting step that occurred after RNA polymerase bound to the promoter. Initiation rates at P[sub spollG] were also stimulated by a truncated form of the SpoOA protein (SpoOA[sup BD]) which contained the DNA binding domain but not the phospho-acceptor site. While transcription stimulation by SpoOA or SpoOA[sup BD] was observed to be extremely salt sensitive, the effect of SpoOA-P was insensitive to salt concentration if the predominant anion was acetate. DNaseI protection experiments demonstrated that both SpoOA and SpoOA-P catalyzed structural changes in ternary complexes formed between RNA polymerase and P[sub spollG]. These isomerizations appeared to correlate with the modest and dramatic effects of SpoOA and SpoOA-P, respectively, on P[sub spollG] transcription. DNaseI protection patterns obtained at various temperatures showed that although protein binding appeared normal, low temperature prohibited the structural transformations attributed to SpoOA(-P). Footprinting experiments carried out on a mutant promoter construct(Psp0llG[sup M94/84])indicated that SpoOA binding sites located at -94 and -84 relative to the transcription start site, are dispensable to the effect of SpoOA(-P) on ternary complex isomerization. However, these sites may function to enhance factor binding to what seem to be the crucial OA boxes at -50 and -40. The biochemical analysis presented in this thesis supports the hypothesis that the phosphorelay functions as a signal transduction system that can induce a sporulation response through activation of the transcription regulating properties of SpoOA.

description: This manuscript provides a new framework for calibration of optical instruments, in particular mobile cameras, using large-scale circular black and white target fields. New methods were introduced for (i) matching targets between images; (ii) adjusting the systematic eccentricity error of target centers; and (iii) iteratively improving the calibration solution through a free-network self-calibrating bundle adjustment. It was observed that the proposed target matching effectively matched circular targets in 270 mobile phone images from a complete calibration laboratory with robustness to Type II errors. The proposed eccentricity adjustment, which requires only camera projective matrices from two views, behaved synonymous to available closed-form solutions, which require several additional object space target information a priori. Finally, specifically for the case of the mobile devices, the calibration parameters obtained using our framework was found superior compared to in-situ calibration for estimating the 3D reconstructed radius of a mechanical pipe (approximately 45% improvement).
An improved global analysis of nuclear parton distribution functions including RHIC data

description: We present an improved leading-order global DGLAP analysis of nuclear parton distribution functions (nPDFs), supplementing the traditionally used data from deep inelastic lepton-nucleus scattering and Drell-Yan dilepton production in proton-nucleus collisions, with inclusive high-$p_T$ hadron production data measured at RHIC in d+Au collisions. With the help of an extended definition of the $χ^2$ function, we now can more efficiently exploit the constraints the different data sets offer, for gluon shadowing in particular, and account for the overall data normalization uncertainties during the automated $χ^2$ minimization. The very good simultaneous fit to the nuclear hard process data used demonstrates the feasibility of a universal set of nPDFs, but also limitations become visible. The high-$p_T$ forward-rapidity hadron data of BRAHMS add a new crucial constraint into the analysis by offering a direct probe for the nuclear gluon distributions -- a sector in the nPDFs which has traditionally been very badly constrained. We obtain a strikingly stronger gluon shadowing than what has been estimated in previous global analyses. The obtained nPDFs are released as a parametrization called EPS08.

The measured peak shapes indicate two regimes of response: simple FMR and phase locking. Studies of the resonance frequencies, amplitudes, and linewidths as a function of microwave power, DC current, and magnetic field provide detailed new information about the exchange, damping, and spin-transfer torques that govern the dynamics in magnetic nanostructures.

description: The holographic dual of a finite-temperature gauge theory with a small number of flavours typically contains D-brane probes in a black hole background. We have recently shown that these systems undergo a first order phase transition characterised by a `melting' of the mesons. Here we extend our analysis of the thermodynamics of these systems by computing their free energy, entropy and energy densities, as well as the speed of sound. We also compute the meson spectrum for brane embeddings outside the horizon and find that tachyonic modes appear where this phase is expected to be unstable from thermodynamic considerations.

description: We report the discovery of the wide L1.5+L4.5 binary 2MASS J15200224-4422419AB, identified during spectroscopic followup of high proper motion sources selected from the Two Micron All Sky Survey. This source was independently identified by Kendall et al. in the SuperCOSMOS Sky Survey. Resolved JHK photometry and low resolution near-infrared spectroscopy demonstrate that this system is composed of two well-separated (1"174+/-0"016) L dwarfs. Component classifications are derived using both spectral ratios and comparison to near-infrared spectra of previously classified field L dwarfs. Physical association for the pair is deduced from the large (mu = 0"73+/-0"03 /yr) common proper motion of the components and their similar spectrophotometric distances (19+/-2 pc). The projected separation of the binary, 22+/-2 AU, is consistent with maximum separation/total system mass trends for very low mass binaries. The 2MASS J1520-4422 system exhibits both large tangential (66+/-7 km/s) and radial velocities (-70+/-18 km/s), and its motion in the local standard of rest suggests that it is an old member of the Galactic disk population. This system joins a growing list of well-separated (>0"5), very low mass binaries, and is an excellent target for resolved optical spectroscopy to constrain its age as well as trace activity/rotation trends near the hydrogen-burning limit.

description: The electrical resistivity of a single crystal of MnSi was measured across its ferromagnetic phase transition line at ambient and high pressures. Sharp peaks of the temperature coefficient of resistivity characterize the transition line. Analysis of these data shows that at pressures to ~0.35 GPa these peaks have fine structure, revealing a shoulder at ~ 0.5 K above the peak. It is symptomatic that this structure disappears at pressures higher than ~0.35 GPa, which was identified earlier as a tricritical point

We study the stratification of AS_g by p-rank into strata AS_{g,s} of Artin-Schreier curves of genus g with p-rank exactly s. We enumerate the irreducible components of AS_{g,s} and find their dimensions. As an application, when p=2, we prove that every irreducible component of the moduli space of hyperelliptic k-curves with genus g and 2-rank s has dimension g-1+s. We also determine all pairs (p,g) for which AS_g is irreducible. Finally, we study deformations of Artin-Schreier curves with varying p-rank. Keywords: Artin-Schreier, hyperelliptic, curve, moduli, p-rank.

description: This project deals with the vegistration, organisathion and materialization of a church sponsored museum in the village of Vafe in Crete. The main goal of the project is to facilitate the access of the history and the village customs throught the Greek Orthodox tradition and the temples of the region. In this assignment, the entire territory is being treated as a museum entity, since in 2000, this settlement was declared National Patrimony, belonging to a much wider conglomeration which maintains its intense religious and cultural character. The planning of the project focuses on the two already exsting constructions which will be used as exibition halls where the collection will be exposed. Therefore, what is being suggested is a cultural itinerary which will lead to the two domes and the central church of the village. What is realy emphasized throught this exibition is the relationship between the community and the church in an effort to promote the folk and tradition of the village. This assignment aims at the registration and maintainance of the collective memory of the area, while the creation of the eco- museum, aims at a much wider development of the region, through the founding of more works of infrastructrure, which will provide the cultural, social and economic advancement that existed, once upon a time, in this village.

description: We study Hamiltonian form of unfree gauge symmetry where the gauge parameters have to obey differential equations. We consider the general case such that the Dirac-Bergmann algorithm does not necessarily terminate at secondary constraints, and tertiary and higher order constraints may arise. Given the involution relations for the first-class constraints of all generations, we provide explicit formulas for unfree gauge transformations in the Hamiltonian form, including the differential equations constraining gauge parameters. All the field theories with unfree gauge symmetry share the common feature: they admit sort of "global constants of motion" such that do not depend on the local degrees of freedom. The simplest example is the cosmological constant in the unimodular gravity. We consider these constants as modular parameters rather than conserved quantities. We provide a systematic way of identifying all the modular parameters. We demonstrate that the modular parameters contribute to the Hamiltonian constraints, while they are not explicitly involved in the action. The Hamiltonian analysis of the unfree gauge symmetry is precessed by a brief exposition for the Lagrangian analogue, including explicitly covariant formula for degrees of freedom number count. We also adjust the BFV-BRST Hamiltonian quantization method for the case of unfree gauge symmetry. The main distinction is in the content of the non-minimal sector and gauge fixing procedure. The general formalism is exemplified by traceless tensor fields of irreducible spin $s$ with the gauge symmetry parameters obeying transversality equations.

description: In this work, we develop a pipeline for historical-psychological text analysis in classical Chinese. Humans have produced texts in various languages for thousands of years; however, most of the computational literature is focused on contemporary languages and corpora. The emerging field of historical psychology relies on computational techniques to extract aspects of psychology from historical corpora using new methods developed in natural language processing (NLP). The present pipeline, called Contextualized Construct Representations (CCR), combines expert knowledge in psychometrics (i.e., psychological surveys) with text representations generated via transformer-based language models to measure psychological constructs such as traditionalism, norm strength, and collectivism in classical Chinese corpora. Considering the scarcity of available data, we propose an indirect supervised contrastive learning approach and build the first Chinese historical psychology corpus (C-HI-PSY) to fine-tune pre-trained models. We evaluate the pipeline to demonstrate its superior performance compared with other approaches. The CCR method outperforms word-embedding-based approaches across all of our tasks and exceeds prompting with GPT-4 in most tasks. Finally, we benchmark the pipeline against objective, external data to further verify its validity.

description: We consider a family of surfaces of revolution ranging between a disc and a hemisphere, that is spherical caps. For this family, we study the spectral density in the ray limit and arrive at a trace formula with geodesic polygons describing the spectral fluctuations. When the caps approach the hemisphere the spectrum becomes equally spaced and highly degenerate whereas the derived trace formula breaks down. We discuss its divergence and also derive a different trace formula for this hemispherical case. We next turn to perturbative corrections in the wave number where the work in the literature is done for either flat domains or curved without boundaries. In the present case, we calculate the leading correction explicitly and incorporate it into the semiclassical expression for the fluctuating part of the spectral density. To the best of our knowledge, this is the first calculation of such perturbative corrections in the case of curvature and boundary.

description: Angle resolved photoelectron spectroscopic measurements have been performed on an insulating cuprate Ca_2CuO_2Cl_2. High resolution data taken along the Γto (pi,pi) cut show an additional dispersive feature that merges with the known dispersion of the lowest binding energy feature, which follows the usual strongly renormalized dispersion of ~0.35 eV. This higher energy part reveals a dispersion that is very close to the unrenormalized band predicted by band theory. A transfer of spectral weight from the low energy feature to the high energy feature is observed as the Γpoint is approached. By comparing with theoretical calculations the high energy feature observed here demonstrates that the incoherent portion of the spectral function has significant structure in momentum space due to the presence of various energy scales.

Moreover, using a capacity calculation model, along with the excel software, the effect of various parameters on railway capacity is being examined. The result of this procedure is the extraction of charts, as well as the calibration of the effect of each parameter. Finally, the capacity of a large part of the greek railway network is being calculated, using the U.I.C. (Fiche 405-1) method, through the same simulation model. Initially, the technical and operational characteristics of the network are being presented and all the scheduled trains are being written down. When the data base is ready, the simulation model is being applied and so the capacity of the examined line sections is being calculated; also, the degree of saturation of these line sections is being calculated, as well, and general conclusions are being extracted.
Anatomical evidence for segregated processing streams in the cat’s visual cortex

description: Studies in primates suggest the existence of at least three separate systems operating in parallel and specialized to process information about: 1) shape; 2) colour; and 3) motion. In visual cortex, these systems are segregated into either the “blobs” staining densely for cytochrome oxidase (CO), or the less densely staining interbiobs. Recent reports of CO blobs in the cat led to this investigation to determine whether CO blobs in this species also act to segregate inputs and outputs. LGN inputs to cat Vi arise from three classes of cells, known as X, Y, and W cells. W cell input was found in different layers of areas 17 and 18 than the X and Y cell input and was localized to CO blobs but not interblobs. The Y cell input from layer C was also found to be confined to the blobs. Area 17 has five major output pathways; to areas 18, 19, 20a, 21a, and the posterior medial lateral suprasylvian area (PMLS). In areas 17 and 18, PMLS-projecting cells were clustered within the CO blobs. Labeling from injections in PMLS was also observed in other cortical areas, and was always clustered, most notably in area 19, where clusters of labeled cells were much wider than in other areas, and often elongated in a direction perpendicular to the 18/19 border. Large injections of tracers into area 19 labeled both blobs and interblobs in areas 17 and 18 while small injections often labeled either only blobs, or only interblobs. Labeling of the callosal pathway, while dense and uniform at the 17/18 border, showed, at the edges of the labeling pattern in areas 17 and 18, regular fluctuations of labeling density that aligned with the CO blobs. Together, these results provide the first demonstration of segregated visual processing streams in a non-primate species. Such an organization may be a general characteristic of mammalian visual cortical organization and not a primate specialization, as was once thought. Knowledge of these pathways in cats, a frequently used system for many developmental and physiological studies, should prove valuable.

description: We analyze the electronic Green's functions in the superconducting ground state of the t-J model using Gutzwiller-projected wave functions, and compare them to the conventional BCS form. Some of the properties of the BCS state are preserved by the projection: the total spectral weight is continuous around the quasiparticle node and approximately constant along the Fermi surface. On the other hand, the overall spectral weight is reduced by the projection with a momentum-dependent renormalization, and the projection produces electron-hole asymmetry in renormalization of the electron and hole spectral weights. The latter asymmetry leads to the bending of the effective Fermi surface which we define as the locus of equal electron and hole spectral weight.

description: As a necessary step in constructing elliptic matrix models, which preserve the superintegrability property $\sim {\rm char}$, we suggest an elliptic deformation of the peculiar loci $p_k^{Δ_n}$, which play an important role in precise formulation of this property. The suggestion is to define the $p_k^{Δ_n}$-loci as elliptic functions with the right asymptotics at $τ\to i\infty$. If this hypothesis is correct, one can move to substituting the Schur and Macdonald functions in the role of characters by the elliptic GNS and study their behavior at the deformed topological and $Δ$ loci.

description: We derive black hole masses for a sample of about 300 AGNs in the redshift range 0 < z < 2.5. We use the same virial velocity measure (FWHM Hbeta broad component) for all sources which represents a significant improvement over previous studies. We review methods and caveats for determining AGN black hole masses via the virial assumption for motions in the gas producing low ionization broad emission lines. We derive a corrected FWHM measure for the broad component of H-beta that better estimates the virialized line emitting component by comparing our FWHM measures with a sample of reverberated sources with H-beta radial velocity dispersion measures. We also consider the FWHM of the FeII 4570 blend as a potential alternative velocity estimator. We find a range of black hole mass between log M ~ 6 - 10, where the black hole mass M is in solar masses. Estimates using corrected FWHM, as well as FWHM(Fe II) measures, reduce the number of sources with log M > 9.5 and suggest that extremely large M values (log M >~ 10) may not be realistic. Derived Eddington ratio values values show no evidence for a significant population of super-Eddington radiators especially after correction is made for sources with extreme orientation to our line of sight.

description: We generalize the description of the d=4 Attractor Mechanism based on an effective black hole (BH) potential to the presence of a gauging which does not modify the derivatives of the scalars and does not involve hypermultiplets. The obtained results do not rely necessarily on supersymmetry, and they can be extended to d>4, as well. Thence, we work out the example of the stu model of N=2 supergravity in the presence of Fayet-Iliopoulos terms, for the supergravity analogues of the magnetic and D0-D6 BH charge configurations, and in three different symplectic frames: the SO(1,1)^{2}, SO(2,2) covariant and SO(8)-truncated ones. The attractive nature of the critical points, related to the semi-positive definiteness of the Hessian matrix, is also studied.

Linear growth of spiral SASI modes in core-collapse supernovae

description: Two-dimensional axisymmetric simulations have shown that the post-bounce accretion shock in core collapse supernovae is subject to the Spherical Accretion Shock Instability, or SASI. Recent three-dimensional simulations have revealed the existence of a non-axisymmetric mode of the SASI as well, where the postshock flow displays a spiral pattern. Here we investigate the growth of these spiral modes using two-dimensional simulations of the post-bounce accretion flow in the equatorial plane of a core-collapse supernova. By perturbing a steady-state model we are able to excite both one, two and three-armed spiral modes that grow exponentially with time, demonstrating that these are linearly unstable modes closely related to the original axisymmetric sloshing modes. By tracking the distribution of angular momentum, we show that these modes are able to efficiently separate the angular momentum of the accretion flow (which maintains a net angular momentum of zero), leading to a significant spin-up of the underlying accreting proto-neutron star.

description: Quasielastic scattering excitation function at large backward angle has been measured for the weakly bound system, $^{7}$Li+$^{159}$Tb at energies around the Coulomb barrier. The corresponding quasielastic barrier distribution has been derived from the excitation function, both including and excluding the $α$-particles produced in the reaction. The centroid of the barrier distribution obtained after inclusion of $α$-particles was found to be shifted higher in energy, compared to the distribution excluding the $α$-particles. The quasielastic data, excluding the $α$-particles, have been analyzed in the framework of continuum discretized coupled channel calculations. The quasielastic barrier distribution for $^{7}$Li+$^{159}$Tb, has also been compared with the fusion barrier distribution for the system.

description: Με τη στροφή των σχεδιαστών στην ενσωμάτωση πολλών επεξεργαστικών στοιχείων χαμηλότερης απόδοσης σε ένα chip, η on-chip interconnection άρχισε να γίνεται ο κύριος παράγων καθορισμού της απόδοσης των IC. οι κλασσικές μεθοδολογίες όπως τα buses και η point to point διασύνδεση αντιμετωπίζουν σοβαρά προβλήματα. επομένως εμφανίστηκε η ανάγκη μιας νέας μεθοδολογίας διασύνδεσης επεξεργαστικών στοιχείων σε ένα chip. το network-on-chip (noC) είναι μία νέα αρχιτεκτονική διασύνδεσης εμπνευσμένη από τον τομέα των δικτύων, υπόσχεται να εξαλείψει ένα μεγάλο μέρος των προβλημάτων που εμφανίζουν οι κλασσικές μεθοδολογίες διασύνδεσης. η ομοιότητα της με τον κλάδο των δικτύων αποτελεί πλεονέκτημα. όμως οι περιορισμοί που επιβάλλει η vlsi σχεδίαση περιορίζουν τη δυνατότητα υιοθέτησης τεχνικών από τον κλάδο των δικτύων, όπου ο χώρος, η κατανάλωση ενεργείας και η καθυστέρηση είναι βασικά κριτήρια. από την άλλη ως ώριμη μέθοδος που ακόμα είναι στο ερευνητικό στάδιο εμφανίζει νέες προκλήσεις σε θέματα σχεδίασης και υλοποίησης.στην εργασία αυτή γίνεται η μελέτη της απόδοσης ενός on-chip δικτύου σε ένα σύστημα με πολλαπλούς επεξεργαστές. το δίκτυο ονομάζεται sparcnoc και προτείνεται από την εταιρία Sun για την αντικατάσταση του τρόπου επικοινωνίας του opensparc t1. η προσομοίωση γίνεται με τη γλώσσα systemc.
description: With designers turning to the incorporation of many procedural units of lower performance in one chip, the on-chip interconnection started becoming the main deciding factor concerning the performance of IC. classic methodologies, such as buses and point-to-point interconnection , face serious problems. as a result, the need for a new methodology of interconnection of procedural units in one chip was created. the network-on-chip (noc) is a new architecture of interconnection inspired from the networks sector and it promises to eliminate many of the problems that plague the classic methodologies of interconnection. its similarity with the network sector is an advantage, but the restrictions imposed by the vlsi design limit the possibility of adoption of techniques from the network sector , where space,power consumption and delay are critical criteria. on the other hand, it being a mature method still in the research stage, it presents new challenges on the topics of design and implementation. in this assignment, we study the performance of an on-chip network in a system with multiple processors. the network is named sparcnoc and it is proposed by Sun for the replacement of opensparc t1's way of communication. The simulation is done by using the language systemc.
