description: The increasing role of home automation in routine life and the rising demand for sensor networks enhanced wireless personal area networks (WPANs) development, pervasiveness of wireless & wired network, and research. Soon arose the need of implementing the Internet Protocol in these devices in order to WPAN standards, raising the way for questions on how to provide seamless communication between wired and wireless technologies. After a quick overview of the Low-rate WPAN standard (IEEE 802.15.4) and the Zigbee stack, this paper focuses on understanding the implications when interconnecting low powered IEEE 802.15.4 devices and a wired IPv6 domain. Subsequently the focus will be on existing approaches to connect LoWPAN devices to the internet and on how these approaches try to solve these challenges, concluding with a critical analysis of interoperability problems.

Third moments of conserved charges in QCD phase diagram

description: We point out that the third moments of conserved charges, the baryon and electric charge numbers, and energy, as well as their mixed moments, change their signs around the QCD phase boundary in the temperature and baryon chemical potential plane. These signs can be measured in relativistic heavy ion collisions, and will give clear information on the phase structure of QCD and the state of the system in the early stage of relativistic heavy ion collisions. The behaviors of these moments on the temperature axis and at small quark chemical potential can be analyzed in lattice QCD simulations. We emphasize that the third moments obtained on the lattice, together with the experimental results, will provide a deep understanding about the QCD phase diagram and the location of the state created in heavy ion collisions.

description: Low-lying energy levels of two interacting electrons confined in a two-dimensional parabolic quantum dot in the presence of an external magnetic field have been revised within the frame of a novel model. The present formalism, which gives closed algebraic solutions for the specific values of magnetic field and spatial confinement length, enables us to see explicitly individual effects of the electron correlation.

High-Order Coupled Cluster Method (CCM) Calculations for Quantum Magnets with Valence-Bond Ground States

description: In this article, we prove that exact representations of dimer and plaquette valence-bond ket ground states for quantum Heisenberg antiferromagnets may be formed via the usual coupled cluster method (CCM) from independent-spin product (e.g. Néel) model states. We show that we are able to provide good results for both the ground-state energy and the sublattice magnetization for dimer and plaquette valence-bond phases within the CCM. As a first example, we investigate the spin-half $J_1$--$J_2$ model for the linear chain, and we show that we are able to reproduce exactly the dimerized ground (ket) state at $J_2/J_1=0.5$. The dimerized phase is stable over a range of values for $J_2/J_1$ around 0.5. We present evidence of symmetry breaking by considering the ket- and bra-state correlation coefficients as a function of $J_2/J_1$. We then consider the Shastry-Sutherland model and demonstrate that the CCM can span the correct ground states in both the Néel and the dimerized phases. Finally, we consider a spin-half system with nearest-neighbor bonds for an underlying lattice corresponding to the magnetic material CaV$_4$O$_9$ (CAVO). We show that we are able to provide excellent results for the ground-state energy in each of the plaquette-ordered, Néel-ordered, and dimerized regimes of this model. The exact plaquette and dimer ground states are reproduced by the CCM ket state in their relevant limits.

description: Vor dem Hintergrund dauerhafter Transformation asiatischer Großstädte bildet diese Arbeit eine Auseinandersetzung mit dem urbanen Phänomen ‚Bangs‘ und dem etablierten Verständnis von öffentlich und privat im städtischen Raum in Seoul, Hauptstadt von Südkorea. Seouls Stadtbild präsentiert sich weder modern noch traditionell, geformt durch die Entwicklung einer Stadt mit weniger als 1 Millionen Einwohnern zu einer hochentwickelten Megapolis mit 23 Millionen Bewohnern innerhalb eines Zeitraums von nur 60 Jahren. Das extreme Wachstum der Stadt führt zu einer hohen Dichte und einer generellen Knappheit an Räumen sowohl zum Wohnen als auch für das öffentlichen Leben, wodurch ungeplante kommerzielle Orte entstanden, genannt ‚Bangs‘. Diese Räume besitzen besondere urbane Qualitäten und sind nur schwer mit traditionellen westlichen Theorien zu beschreiben, die Grenzen zwischen Wohnen und Stadt verwischen. Interaktionen in Bangs können weder als öffentlich noch privat verstanden werden, es kann mehr als Räume dazwischen angesehen werden, wo sich privates Leben im öffentlichen Umfeld abspielt. Die Arbeit untersucht zudem, welche Rolle die Architektur bei der stetigen Veränderung der ‚Bangs‘ und dem urbanen Kontext einnimmt.
description: Against the backdrop of the continuous transformation of Asian cities, this thesis examines the urban phenomenon 'Bangs' by discussing the established understanding of public and private urban space in Seoul, the capital of South Korea. Seoul's cityscape presents itself as neither modern nor traditional, shaped by the transformation of a city with less than 1 million inhabitants into a highly developed megapolis with 23 million inhabitants within only 60 years. The extreme growth of the city led to high density and a shortage of spaces for both housing and public life. Due to these circumstances, new spaces were created, commercial places called 'Bangs' with unique urban qualities. They blur boundaries between residential and urban and are not easy to explain with traditional Western theories. Interactions in Bangs can neither be understood as public nor private. These spaces can be seen as rooms in between, where private life takes place in a public environment. The thesis also explores the role of architecture in the constant transformation of the ‘Bangs’ and the urban context.

Un’informazione cruciale per capire meglio i meccanismi che lo hanno generato e hanno liberato l'immane quantità di energia misurata

description: Both algebraic and computational approaches for dealing with similarity spaces are well known in generalized rough set theory. However, these studies may be said to have been confined to particular perspectives of distinguishability in the context. In this research, the essence of an algebraic semantics that can deal with all possible concepts of distinguishability over similarity spaces is progressed. Key to this is the addition of choice-related operations to the semantics that have connections with modal logics as well. Among these we focus on a semantics that is based on local clear distinguishability over similarity spaces.

Ai buchi neri supermassicci piace il sapore dell’idrogeno e dell’elio. Ma cosa accade esattamente quando azzannano una stella? Uno studio uscito su ApJ Letters propone un modello unificato, basato su simulazioni numeriche, per spiegare ciò che gli astronomi osservano. Ne parliamo con un esperto dell’Inaf di Brera, l’astrofisico Gabriele Ghisellini

description: We investigate the star formation history of the universe using FIREWORKS, a multiwavelength survey of the CDFS. We study the evolution of the specific star formation rate (sSFR) with redshift in different mass bins from z = 0 to z ~ 3. We find that the sSFR increases with redshift for all masses. The logarithmic increase of the sSFR with redshift is nearly independent of mass, but this cannot yet be verified at the lowest-mass bins at z > 0.8, due to incompleteness. We convert the sSFRs to a dimensionless growth rate to facilitate a comparison with a semi-analytic galaxy formation model that was implemented on the Millennium Simulation. The model predicts that the growth rates and sSFRs increase similarly with redshift for all masses, consistent with the observations. However, we find that for all masses, the inferred observed growth rates increase more rapidly with redshift than the model predictions. We discuss several possible causes for this discrepancy, ranging from field-to-field variance, conversions to SFR, and shape of the IMF. We find that none of these can solve the discrepancy completely. We conclude that the models need to be adapted to produce the steep increase in growth rate between redshift z=0 and z=1.

description: Multiprocessor task scheduling is an important and computationally difficult problem. This paper proposes a comparison study of genetic algorithm and list scheduling algorithm. Both algorithms are naturally parallelizable but have heavy data dependencies. Based on experimental results, this paper presents a detailed analysis of the scalability, advantages and disadvantages of each algorithm. Multiprocessors have emerged as a powerful computing means for running real-time applications, especially where a uni-processor system would not be sufficient enough to execute all the tasks. The high performance and reliability of multiprocessors have made them a powerful computing resource. Such computing environment requires an efficient algorithm to determine when and on which processor a given task should execute. In multiprocessor systems, an efficient scheduling of a parallel program onto the processors that minimizes the entire execution time is vital for achieving a high performance. This scheduling problem is known to be NP- Hard. In multiprocessor scheduling problem, a given program is to be scheduled in a given multiprocessor system such that the program's execution time is minimized. The last job must be completed as early as possible. Genetic algorithm (GA) is one of the widely used techniques for constrained optimization.

Interaction of waves and a shear flow

description: A series of experiments has been undertaken in which three major properties of a surface tension-gravity wave system have been critically examined. The results of these experiments have been compared with existing theories. The three properties are: viscous decay in the absence of mean flow, which has been compared to the theory given in Lamb (1932) #348; propagation velocities in the presence and absence of mean flow, compared to Lamb (1932) #267, and the change of wave energy on crossing a stable Couette shear flow, compared to two theories - one obtained from the Navier-Stokes equations including terms up to second order in wave slope; the other, following previous authors, assuming any direct interaction of the waves with the shear flow to be negligible. According to the theory obtained from the Navier-Stokes equations the divergence of the rate of transport of surface wave energy is equal to the rate of change of wave energy due to the interaction of the mean flow and the wave system plus the rate of change of energy due to viscous decay. An optical system was used to measure the maximum wave slope, the wavenumbers and the shear velocities. A grid of point source lights was set up to reflect off a previously chosen part of the shear flow into a properly oriented camera. A series of pulses of waves, generated by an electromechanical transducer, were then sent across this region of the flow. For each pulse of waves a photograph was taken of the oscillating images of the lights with the exposure time longer than one wave period. The resulting streaks on the film are proportional to the maximum wave slopes at the positions from which the undeviated light reflects. A series of parallel straight white strings were photographed with the aid of a flash unit when waves crossed the flow. This was then used to determine lines of constant phase from which the wavelength and hence the wavenumber was measured at various positions across the flow. The viscous decay and part of the propagation measurements were obtained in this way but with no mean flow. Results indicate that an anomalous region of wave properties exists for wavenumbers near 2.7 cm. ̄¹. For a set of data in which the wavenumbers were always less than 1.8 cm.̄¹, it was found that the viscous decay rate and the propagation laws agree with theory to within the experimental error, and the interaction measurements fit the theory with the non-linear term included rather than the traditional theories.

Dai dati raccolti dal rivelatore Lhcb al Large Hadron Collider, sembra che le particelle conosciute come mesoni charm e le loro controparti di antimateria non siano prodotte in proporzioni perfettamente uguali. Alcuni fisici di Cracovia hanno proposto una spiegazione di questo fenomeno e presentato le loro previsioni, che comportano conseguenze particolarmente interessanti per l'astronomia dei neutrini ad alta energia. Lo studio è stato pubblicato su Physical Review D

Caldo, insetti e ore interminabili di lavoro: questo e molto altro è lavorare nell'Outback in Australia Occidentale. Tutto per installare antenne a bassa frequenza del progetto Square Kilometre Array. Sono le prime 256 di 130mila e l'installazione verrà completata nei prossimi anni. L'Italia è uno dei partner principali del consorzio che si occupa di queste antenne, dalla simpatica forma ad albero di Natale

description: It has been shown that for each Killing-Yano (KY)-form accepted by an $n$-dimensional (pseudo)Riemannian manifold of arbitrary signature, two basic gravitational currents can be defined. Conservation of the currents are explicitly proved by showing co-exactness of the one and co-closedness of the other. Some general geometrical facts implied by these conservation laws are also elucidated. In particular, the conservation of the one-form currents implies that the scalar curvature of the manifold is a flow invariant for all of its Killing vector fields. It also directly follows that, while all KY-forms and their Hodge duals on a constant curvature manifold are the eigenforms of the Laplace-Beltrami operator, for an Einstein manifold this is certain only for KY 1-forms, $(n-1)$-forms and their Hodge duals.
