An Information-Theoretic Measure for Pattern Similarity in Analog Wafermaps
Creators: name: Geiger, Bernhard C.
name: Schrunner, Stefan
name: Kern, Roman
Publisher: name: Zenodo
Year: 2019

description: The development of automated tools for data analysis is a growing need in semiconductor manufacturing. For this purpose, especially wafer test data carry a high potential as they allow the expert to draw conclusions on both product performance, as well as production process deviations. The latter are assumed to be identifiable by spatial patterns on wafermaps. The target of this work is to propose a system that judges the similarities between wafermaps regarding the depicted process pattern in an automated way. For this purpose, we propose a similarity measure to perform a pairwise comparison of wafermaps based on extracted, high-dimensional features.

description: Thermal ammonolysis of quasi-two-dimensional (quasi-2D) CoTa2O6 yields the O2-/N3- and anionic vacancy ordered Co2+Ta5+2O6-xN2x/3$\Box$x/3 (x $\leq$ 0.15) that exhibits a transition from antiferromagnetism to defect engineered above room-temperature ferromagnetism as evidenced by diffraction, spectroscopic and magnetic characterizations. First-principles calculations reveal the origin of ferromagnetism is a particular CoON configuration with N located at Wyckoff position 8j, which breaks mirror symmetry about ab plane. A pressure-induced electronic phase transition is also predicted at around 24.5 GPa, accompanied by insulator-to-metal transition and magnetic moment vanishing.

description: Recently, Tiwari, Chaubey, & Pandey (2007) detected the bright component of the visual binary HD151878 to exhibit rapid photometric oscillations through a Johnson B filter with a period of 6 min (2.78 mHz) and a high, modulated amplitude up to 22 mmag peak-to-peak, making this star by far the highest amplitude roAp star known. As a new roAp star, HD151878 is of additional particular interest as a scarce example of the class in the northern sky, and only the second known case of an evolved roAp star - the other being HD 116114. We used the FIES spectrograph at the Nordic Optical Telescope to obtain high time resolution spectra at high dispersion to attempt to verify the rapid oscillations. We show here that the star at this epoch is spectroscopically stable to rapid oscillations of no more than a few tens of m/s. The high-resolution spectra furthermore show the star to be of type Am rather than Ap and we show the star lacks most of the known characteristics for rapidly oscillating Ap stars. We conclude that this is an Am star that does not pulsate with a 6-min period. The original discovery of pulsation is likely to be an instrumental artefact.

description: Aims. Near diffraction-limited images have been taken at 8.9, 11.9, and 12.9 micron for the brightest extragalactic sources in the southern sky, in order to optimally plan N-band observations with MIDI (MID-infrared Interferometric instrument) at the VLTI. Methods. We have assembled a sample of 21 objects consisting of all the AGNs observable from Paranal observatory, Chile, plus three non-AGN objects, with an estimated N-band flux greater than 400mJy. We used the TIMMI2 Mid Infrared instrument mounted on the ESO's 3.6m telescope to obtain near diffraction-limited images in order to establish the unresolved core flux within < 0.5 arscsec. Results. Positions and core total fluxes were obtained for all sources in our sample and compared with similar investigations in the literature. We find that 15 AGN and the nuclear starburst in NGC 253 exhibit an unresolved core flux < 300mJy at 11.9 micron, making them promising targets for MIDI at the VLTI. For extended sources, near diffraction-limited images are presented and discussed.

From these data we are able to discuss parameterizations and modeling and make predictions of the nature of the progenitors based on previous research. Derived mass loss rates assume wind-established circumstellar medium, shock velocity ~10,000 km/s, wind velocity ~10 km/s, and CSM Temperature ~10,000 K.

description: The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar Radio Source (in short: radio quasar) 3C 279, at a distance of more than 5 billion light-years (a redshift of 0.536). No quasar has been observed previously in very-high-energy gamma radiation, and this is also the most distant object detected emitting gamma rays above 50 gigaelectron volts. Since high-energy gamma rays may be stopped by interacting with the diffuse background light in the universe, the observations by MAGIC imply a low amount for such light, consistent with that known from galaxy counts.

description: We present a detailed analysis of the one-electron physics of the actinides. Various LMTO basis sets are analyzed in order to determine a robust bare Hamiltonian for the actinides. The hybridization between f- an spd- states is compared with the f-f hopping in order to understand the Anderson-like and Hubbard-like contributions to itineracy in the actinides. We show that both contributions decrease strongly as one move from the light actinides to the heavy actinides, while the Anderson-like contribution dominates in all cases. A real-space analysis of the band structure shows that nearest-neighbor hopping dominates the physics in these materials. Finally, we discuss the implications of our results to the delocalization transition as function of atomic number across the actinide series.

description: We show theoretically that entangled photon pairs can be produced on demand through the biexciton decay of a quantum dot strongly coupled to the modes of a photonic crystal. The strong coupling allows to tune the energy of the mixed exciton-photon (polariton) eigenmodes, and to overcome the natural splitting existing between the exciton states coupled with different linear polarizations of light. Polariton states are moreover well protected against dephasing due to their lifetime ten to hundred times shorter than that of a bare exciton. Our analysis shows that the scheme proposed can be achievable with the present technology.

We use this model to explore the effect of the pseudogap on the real part of the optical conductivity and on the partial sum rule associated with it. An important result is that the optical spectral weight redistributes over a much larger frequency window than it does in the DOS.

title:  Distribuzione del reddito e saggio del profitto in Marx e negli economisti classici: uno studio comparato
Creators: name: Scarano  ,  Giovanni
Publisher: name: RomaTrE-Press
Year: 2023

description: The paper argues that the concern to determine the rate of profit, attributed to the classics by modern surplus approach, was not the main focus in most classical authors before Ricardo. Moreover, this theme did not have a central place in Marx’s analysis at all. In fact, according to Marx, a uniform rate of profit was only one way to determine the distribution of surplus value among the owners of capital in proportion to the capital invested. On the contrary, the distribution of income between capitalists and workers was strictly determined by the rate of surplus value. Moreover, Marx used his own version of the labour theory of value – very different from that of Smith and Ricardo – not to determine the rate of profit and production prices, but to analyse the dynamics of economic aggregates and bring to light the inner social nature of production and distribution processes. In this context, Marx’s rate of profit was only an aggregate measure of the maximum potential growth rate.

description: We consistently formalize the probabilistic description of multipartite joint measurements performed on systems of any nature. This allows us: (1) to specify in probabilistic terms the difference between nonsignaling, the Einstein- Podolsky-Rosen (EPR) locality and Bell's locality; (2) to introduce the notion of an LHV model for an S_{1}x...xS_{N}-setting N-partite correlation experiment, with outcomes of any spectral type, discrete or continuous, and to prove both general and specific "quantum" statements on an LHV simulation in an arbitrary multipartite case; (3) to classify LHV models for a multipartite quantum state, in particular, to show that any N-partite quantum state, pure or mixed, admits an Sx1x...x1 -setting LHV description; (4) to evaluate a threshold visibility for a noisy bipartite quantum state to admit an S_{1}xS_ {2}-setting LHV description under any generalized quantum measurements of two parties. In a sequel to this paper, we shall introduce a single general representation incorporating in a unique manner all Bell-type inequalities for either joint probabilities or correlation functions that have been introduced or will be introduced in the literature.

description: Phonon-polaritons, mixed excitations of light coupled to lattice vibrations (phonons), are emerging as a powerful platform for nanophotonic applications. This is because of their ability to concentrate light into extreme sub-wavelength scales and because of their longer phonon lifetimes than their plasmonic counterparts. In this work, the infrared properties of phonon-polaritonic nanoresonators made of monoisotopic B-10 hexagonal-boron nitride (h-BN) are explored, a material with increased phonon-polariton lifetimes compared to naturally abundant h-BN due to reduced photon scattering from randomly distributed isotopes. An average relative improvement of 50% in the nanoresonators Q factor is obtained with respect of nanoresonators made of naturally abundant h-BN. Moreover, the monoisotopic h-BN nano-ribbon arrays are used to sense nanometric-thick films of molecules, both through surface-enhanced absorption spectroscopy and refractive index sensing. In addition, strong coupling is achieved between a molecular vibration and the phonon-polariton resonance in monoisotopic h-BN ribbons.

description: We study the matter produced in heavy ion collisions assuming that this matter is strongly interacting and employing AdS/CFT correspondence to investigate its dynamics. At late proper times we show that Bjorken hydrodynamics solution, obtained recently by Janik and Peschanski using gauge-gravity duality [hep-th/0512162], can be singled out by simply requiring that the metric tensor is a real and single-valued function of the coordinates everywhere in the bulk, without imposing any constraints on the curvature invariant. At early proper times we use similar strategy to show that the energy density approaches a constant as proper time goes to zero. We therefore demonstrate that the strong coupling dynamics incorporates the isotropization transition in heavy ion collisions. By matching our early-time regime with the late-time one of Janik and Peschanski we estimate the isotropization time at RHIC to be approximately 0.3 fm/c, in good agreement with results of hydrodynamic simulations.

description: Damped Lyman-alpha systems (DLAs) are useful probes of star formation and galaxy formation at high redshift. We study the physical properties of DLAs and their relationship to Lyman-break galaxies using cosmological hydrodynamic simulations based on the concordance Lambda cold dark matter model. Fundamental statistics such as global neutral hydrogen (HI) mass density, HI column density distribution function, DLA rate-of-incidence and mean halo mass of DLAs are reproduced reasonably well by the simulations, but with some deviations that need to be understood better in the future. We discuss the feedback effects by supernovae and galactic winds on the DLA distribution. We also compute the [C_II] emission from neutral gas in high-z galaxies, and make predictions for the future observations by ALMA and SPICA. Agreement and disagreement between simulations and observations are discussed, as well as the future directions of our DLA research.

description: As digital technologies become more prevalent there is a growing awareness of the importance of good security and privacy practices. The tools and techniques used to achieve this are typically designed with the living user in mind, with little consideration of how they should or will perform after the user has died. We report on two workshops carried out with users of password managers to explore their views on the post-mortem sharing, security and privacy of a range of common digital assets. We discuss a post-mortem privacy paradox where users recognise value in planning for their digital legacy, yet avoid actively doing so. Importantly, our findings highlight a tension between the use of recommended security tools during life and facilitating appropriate post-mortem access to chosen assets. We offer design recommendations to facilitate and encourage digital legacy planning while promoting good security habits during life.

Schwarzschild-like Wormholes in Asymptotically Safe Gravity

description: In this paper, we analyze the Schwarzschild-like wormhole in the Asymptotically Safe Gravity(ASG) scenario. The ASG corrections are implemented via renormalization group methods, which, as consequence, provides a new tensor $X_{μν}$ as a source to improved field equations, and promotes the Newton's constant into a running coupling constant. In particular, we check whether the radial energy conditions are satisfied and compare with the results obtained from the usual theory. We show that only in the particular case of the wormhole being asymptotically flat(Schwarzschild Wormholes) that the radial energy conditions are satisfied at the throat, depending on the chosen values for its radius $r_0$. In contrast, in the general Schwarzschild-like case, there is no possibility of the energy conditions being satisfied nearby the throat, as in the usual case. After that, we calculate the radial state parameter, $ω(r)$, in $r_0$, in order to verify what type of cosmologic matter is allowed at the wormhole throat, and we show that in both cases there is the possibility of the presence of exotic matter, phantom or quintessence-like matter. Finally, we give the $ω(r)$ solutions for all regions of space. Interestingly, we find that Schwarzschild-like Wormholes with excess of solid angle of the sphere in the asymptotic limit have the possibility of having non-exotic matter as source for certain values of the radial coordinate $r$. Furthermore, it was observed that quantum gravity corrections due the ASG necessarily imply regions with phantom-like matter, both for Schwarzschild and for Schwarzschild-like wormholes. This reinforces the supposition that a phantom fluid is always present for wormholes in this context.

description: The extreme eigenvalues of connectivity matrices govern the influence of the network structure on a number of network dynamical processes. A fundamental open question is whether the eigenvalues of large networks are well represented by ensemble averages. Here we investigate this question explicitly and validate the concept of ensemble averageability in random scale-free networks by showing that the ensemble distributions of extreme eigenvalues converge to peaked distributions as the system size increases. We discuss the significance of this result using synchronization and epidemic spreading as example processes.

Characteristics of effective and ineffective clinical teachers in nursing as perceived by students and faculty
Creators: name: MacDonald-Clarkson, Christine Marie
Publisher: name: University of British Columbia
Year: 2010

description: The purposes of this study were to investigate the characteristics of effective and ineffective clinical teachers in nursing as perceived by diploma school students and faculty, to compare the two groups in their perceptions, and to determine the influence, if any, that selected student and teacher variables have on these perceptions. The sample included 149 nursing students who had been supervised by at least 3 clinical teachers during their nursing education and 24 faculty. A descriptive survey approach was utilized for this study. Data were gathered using a background information questionnaire, an adapted form of the Nursing Clinical Teacher Effectiveness Inventory (NCTEI), and a Summary form. The NCTEI, developed by Knox and Mogan (1985), contains 48 clinical teacher characteristics grouped into five categories. Subjects were asked to rate an effective and ineffective clinical teacher from their past observations using the NCTEI. They were then requested to list the three characteristics they considered to be most important for clinical teacher effectiveness. Data were analyzed using a variety of statistical procedures. Results showed that students and faculty did describe effective and ineffective clinical teachers in nursing differently. Students emphasized characteristics related to Personality Traits, Interpersonal Relationships, and Evaluation categories while faculty focused on Teaching Ability, Nursing Competence and Evaluation characteristics. The three characteristics selected as most important for clinical teacher effectiveness were also found to differ between the two groups. The student variable of class level influenced the ratings of effective clinical teachers while age influenced the ratings of ineffective clinical teachers. These variables did not affect the three characteristics selected as most important for clinical teacher effectiveness. The faculty variable, number of years of teaching experience, affected ratings of both effective and ineffective clinical teachers. However, the variables of teaching level, employment status, and educational preparation did not. No significant differences were found in the characteristics chosen as the three most important for a clinical teacher to possess across faculty variables. Conclusions and implications of this study are addressed and suggestions for further research are presented.

description: A random Fibonacci sequence is defined by the relation g_n = | g_{n-1} +/- g_{n-2} |, where the +/- sign is chosen by tossing a balanced coin for each n. We generalize these sequences to the case when the coin is unbalanced (denoting by p the probability of a +), and the recurrence relation is of the form g_n = |λg_{n-1} +/- g_{n-2} |. When λ>=2 and 0 < p <= 1, we prove that the expected value of g_n grows exponentially fast. When λ= λ_k = 2 cos(π/k) for some fixed integer k>2, we show that the expected value of g_n grows exponentially fast for p>(2-λ_k)/4 and give an algebraic expression for the growth rate. The involved methods extend (and correct) those introduced in a previous paper by the second author.

description: Wafer test is a crucial step at the end of semiconductor frontend production, where a sequence of electrical measurements is applied to each device on the wafer. The result is a spatial dataset, which can be visualized by plotting the measured parameters for each device on the wafer at their corresponding x-y position, these images are called wafermaps. While wafermaps are commonly used by experts to judge the stability of the production, our intention is to detect spatial patterns on the analog measurement data, as they might reveal deviations in the production process. We aim to quantify patterns with respect to their intensities, indicating the evolution level of a spatial process pattern. This will be achieved by calculating two statistical key figures, Spatial Entropy and Moran’s I, which we apply to simulated data, as well as to a real-world dataset demonstrating the applicability of each method.

description: We explore the zero-shot setting for day-night domain adaptation. The traditional domain adaptation setting is to train on one domain and adapt to the target domain by exploiting unlabeled data samples from the test set. As gathering relevant test data is expensive and sometimes even impossible, we remove any reliance on test data imagery and instead exploit a visual inductive prior derived from physics-based reflection models for domain adaptation. We cast a number of color invariant edge detectors as trainable layers in a convolutional neural network and evaluate their robustness to illumination changes. We show that the color invariant layer reduces the day-night distribution shift in feature map activations throughout the network. We demonstrate improved performance for zero-shot day to night domain adaptation on both synthetic as well as natural datasets in various tasks, including classification, segmentation and place recognition.

description: Motivated by recent experiments on BaCuSi2O6, we investigate magnetic excitations and quantum phase transitions of layered dimer magnets with inter-layer frustration. We consider two scenarios, (A) a lattice with one dimer per unit cell and perfect inter-layer frustration, and (B) an enlarged unit cell with inequivalent layers, with and without perfect frustration. In all situations, the critical behavior at asymptotically low temperatures is three-dimensional, but the corresponding crossover scale may be tiny. Magnetic ordering in case (B) can be discussed in terms of two condensates; remarkably, perfect frustration renders the proximity effect ineffective. Then, the ordering transition will be generically split, with clear signatures in measurable properties. Using a generalized bond-operator method, we calculate the low-temperature magnetic properties in the paramagnetic and antiferromagnetic phases. Based on the available experimental data on BaCuSi2O6, we propose that scenario (B) with inequivalent layers and imperfect frustration is realized in this material, likely with an additional modulation of the inter-layer couling along the c axis.

description: The steep spectrum radio source VLSSJ2217.5+5943 shows a complex, filamentary morphology and a curved spectrum. Therefore, the source has previously been classified as a radio phoenix. However, no galaxy cluster associated with this radio source has been confidently detected so far because the source is located in the direction of the innermost zone of the Galactic Plane at b = +2.4 degr (innermost Zone of Avoidance, ZoA). We analysed archival observations in the near infrared (UKIDSS) and mid infrared (Spitzer) to select the galaxies in the immediate neighbourhood of the radio source. A sample of 23 galaxies was selected as candidate cluster members. Furthermore, we carried out deep integral field spectroscopy covering 6450 to 10500 AA with the red unit of the Hobby-Eberly Telescope second generation low resolution spectrograph (LRS2-R). We also reanalysed archival GMRT observations at 325 and 610 MHz. We selected 23 galaxies within a radius of 2.5 arcmin, centered on RA=22:17.5, DEC=+59:43 (J2000). Spectra were obtained for three of the brightest galaxies. For two galaxies we derived redshifts of z = 0.165 and z = 0.161, based on NaD absorption and TiO band heads. Their spectra correspond to E-type galaxies. Both galaxies are spatially associated with VLSSJ2217.5+5943. The spectrum of the third galaxy, which is slightly more distant from the radio source, indicates a LINER at z = 0.042. It is apparently a foreground galaxy with respect to the cluster we identified. VLSSJ2217.5+5943 is associated with a massive galaxy cluster at redshift z = 0.163 +- .003, supporting its classification as radio phoenix.

description: Vehicle-to-vehicle communications can be used effectively for intelligent transport systems (ITS) and location-aware services. The ability to disseminate information in an ad-hoc fashion allows pertinent information to propagate faster through the network. In the realm of ITS, the ability to spread warning information faster and further is of great advantage to the receivers of this information. In this paper we propose and present a message-dissemination procedure that uses vehicular wireless protocols for influencing traffic flow, reducing congestion in road networks. The computational experiments presented in this paper show how an intelligent driver model (IDM) and car-following model can be adapted to 'react' to the reception of information. This model also presents the advantages of coupling together traffic modelling tools and network simulation tools.

Novel challenges for root cause investigation in semiconductor manufacturing

Year: 2019

description: Due to the constantly growing automation in the semiconductor manufacturing and the associated increasing amount of data, the question of data handling and automated decision making becomes more and more important. Advanced measurement techniques in high-precision and high-tech manufacturing processes lead to more data and hence, enable more monitoring possibilities. Nevertheless, recorded data is only meaningful if evaluated. Common root cause analyses, performed by experts, are mainly based on physical relations and lower order correlations aiming to keep the manufacturing process stable. To investigate higher order correlations, especially if there is an increased data landscape available, needs automated evaluation procedures because manual effort is not feasible anymore. Therefore, novel investigation procedures are needed by means of data- and knowledge-driven analysis methods to support the expert´s routine in order to perform root cause analysis.
Structure of the gene encoding the exoglucanase of Cellulomonas fimi and its expression and secretion in Escherichia coli
Creators: name: O’Neill, Gary Paul
Publisher: name: University of British Columbia

description: In the Gram-positive bacterium Cellulomonas fimi, the pex gene encodes a secreted exoglucanase (Exg) involved in the degradation of cellulose. In order to study the relationship between the structure and function of this cellulase, the nucleotide sequence of the pex gene was determined, and its overproduction in Escherichia coli was obtained to facilitate purification of large amounts of this enzyme. The pex gene was localized to a 2.58-kb BamHI-Sall fragment contained within a 6.6-kb BamHI fragment of C. fimi DNA, and its nucleotide sequence was determined. The pex coding region of 1452-bp (484 codons) was identified by comparison of the DNA sequence to the amino terminal amino acid sequence of the Exg produced by C. fimi. In the gene, the region encoding the amino terminus of the mature Exg is preceded by a sequence encoding a putative signal peptide of 41 amino acids, a translational initiation codon and a ribosome binding site. The nucleotide sequence immediately following the translational stop codon contained four inverted repeats, two of which overlap. A dramatic (98.5%) bias occurs for guanosineor cytosine in the third position of the 35 codons utilized in the pex, The ability of the proposed 41 amino acid signal peptide to direct secretion from E. coli was shown by gene fusion experiments. A hybrid leader sequence containing the 6 amino-terminal amino acids of β-galactosidase (βGal) followed by the 37 amino acids of the carboxyl end of the leader peptide directed export of Exg into the periplasm of Lpoli In contrast, hybrid βGal-Exg proteins in which the leader sequence was not present were located in the cytoplasm. In an attempt to optimize the secretion of the Exg from E. poll, the Exg signal peptide W8S replaced with the signal peptide from the OmpA protein to yield an OmpA-Exg hybrid protein. The OmpA-Exg hybrid protein retained biological activity and was secreted into the periplasmic space of E. poll. A series of operon and gene fusions between various E. coli operons and the Exg coding sequence was carried out in order to optimize the expression of Exg in E. coli. The highest level of Exg production exceeded 20% of the total cellular protein. To obtain this level of overproduction, the Exg coding sequence was fused to a synthetic ribosome binding site, with an initiating ATG, and was placed under the control of the leftward promoter of phage lambda contained on a runaway replication plasmid vector.

description: We present a pixelized source reconstruction method applied on Integral Field Spectroscopic (IFS) observations of gravitationally lensed galaxies. We demonstrate the effectiveness of this method in a case study on the clumpy morphology of a $z \sim 2$ lensed galaxy behind a group-scale lens. We use a Bayesian forward source modelling approach to reconstruct the surface brightness distribution of the source galaxy on a uniformly pixelized grid while accounting for the image point spread function (PSF). The pixelated approach is sensitive to clump sizes down to 100 pc and resolves smaller clump sizes with an improvement in the signal to noise ratio (SNR) by almost a factor of ten compared with more traditional ray-tracing approaches.

Energy dependence of jet transport parameter and parton saturation in quark-gluon plasma

description: We study the evolution and saturation of the gluon distribution function in the quark-gluon plasma as probed by a propagating parton and its effect on the computation of jet quenching or transport parameter $\hat{q}$. For thermal partons, the saturation scale $Q^2_s$ is found to be proportional to the Debye screening mass $μ_D^2$. For hard probes, evolution at small $x=Q^2_s/6ET$ leads to jet energy dependence of $\hat{q}$. We study this dependence for both a conformal gauge theory in weak and strong coupling limit and for (pure gluon) QCD. The energy dependence can be used to extract the shear viscosity $η$ of the medium since $η$ can be related to the transport parameter for thermal partons in a transport description. We also derive upper bounds on the transport parameter for both energetic and thermal partons. The later leads to a lower bound on shear viscosity-to-entropy density ratio which is consistent with the conjectured lower bound $η/s\geq 1/4π$. We also discuss the implications on the study of jet quenching at the BNL Relativistic Heavy Ion Collider and the CERN Large Hadron Collider and the bulk properties of the dense matter.

Mobile Ad Hoc Networks: the DHT paradigm
Creators: name: Caleffi, Marcello
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: In this thesis, the adoption of the hierarchical routing paradigm to achieve a scalable network layer for ad hoc networks has been proposed. The main concept of hierarchical routing is to keep, at any node, complete routing information about nodes which are close to it and lesser information about nodes located further away.
The Augmented Tree-based Routing protocol, a routing protocol for ad hoc networks exploiting both a location-aware addressing schema and a distribute hash table (DHT) system, has been proposed. The adopted addressing schema allows nodes to adopt hierarchical routing, limiting so the overhead introduced in the network, while the DHT system provides the mapping between transient identifiers and node identities.
Since the Augmented Tree-based Routing protocol adopts a multi-path strategy and since most studies in the area of multi-path routing focus on heuristic methods and the performances of these strategies are commonly evaluated by numerical simulations, an analytical framework to evaluate the performance gain achieved by multi-path routing has been proposed. The framework
is based on on graph theory and on terminal-pair routing reliability (TPRR) as performance measure.
Moreover, some features of the proposed protocol has been exploited design a peer-to-peer (P2P) system over a mobile ad hoc network (MANET) resorting to a cross-layer approach. It has been proved that simply deploying P2P systems over MANETs may cause poor performances. By coupling both the direct and the indirect key-based routing at the network layer and by resorting to the same hierarchical address space structure of ATR, we are able to build a P2P overlay network in which the logical proximity agrees with the physical one, limiting so the message overhead and avoiding the redundancy.
Finally, by extending the proposed location-aware addressing to match with the opportunistic forwarding protocol, a novel routing protocol for disruption tolerant network (DTN) and delay tolerant network (DTN) has been proposed. By exploiting both the temporal diversity and the broadcast nature of the wireless propagation, such a protocol can enable connectivity in ad hoc environments characterized by non stationary wireless propagation as well as sparse topologies.
