Design to Achieve Accuracy in Ink-Jet Cylindrical Printing Machines

Machines for direct digital inkjet printing on cylindrical containers are a new technology out on the market. The commercialization in the industrial sector has been affected by their high precision. This led to the use of mechanisms with narrow manufacturing tolerances and to the searches for topologies that have the least accumulated error without affecting quality. Machines with topologies that work on flat substrates have printing and productivity problems working on cylindrical substrates. This research paper presents the qualitative design of direct digital inkjet printers working over cylindrical substrates comparing five mechanical topologies; three topologies with radial distribution and two topologies with parallel distribution. The aim of these topologies is to find the precision, quality and efficiency of the printer taking into account the restrictions present in its construction. Each topology has separate constitutive mechanisms, the tolerance ranges between the movements of the print head and the substrate in order to determine precision are analyzed. Out of the five topologies described and analyzed in the phase diagram in section 3, three of them meet the requirements. One of the three topologies that meet the requirements is not being developed due to current technological limitations.

Using Social Networks in a Large-Scale Online Community of Software Development Projects

The scale-free network shown in the small world phenomenon indicates that our human society consists of a small number of people who play the role of hubs linked with many nodes (persons) and a large number of people as nodes linked with few nodes. From our analysis of a large-scale online community— SourceForge.net which has a large number of developers and projects, we have found that SourceForge also exists as a scale-free network. That is, only a minority of developers join many projects and have rich links with other developers, while the majority join few projects and have very limited social relations with others. The goal of our study is to build a system that supports knowledge collaboration in a large-scale online community of software development projects. In this paper, we discuss the challenges of supporting knowledge collaboration in such a large online community that is a scale-free network and then introduce the prototype system called D¬SNS (Dynamic Social Networking System).
Automated Code Generation for NFC-based Access Control

Access control systems provide a security application for controlling access of persons through controlled gates. The gate, such as a door, can have a lock mechanism for securing the area from unauthorized access. Radio Frequency Identification (RFID) / Near Field Communication (NFC) is a key technology for sensor communication enabling a ubiquitous and pervasive computing network, popularly employed in access control systems. In this paper we investigate a case study about the migration of an old chip card based access control system to this new way of authorizing people, based on NFC tags. To this aim, we propose a Model Driven approach that supports (semi) automatic code generation for enabling the communication between an IoT infrastructure and platforms for Facility Access Management. Specifically, the approach combines the benefits of NFC and Tinkerforge (i.e., an open source hardware platform) technologies with model driven techniques. As a consequence, it allows the reduction of the implementation efforts, by also providing snippets as exemplary code usage, while making the whole development process less error-prone and time consuming.
Mechanics of tidal and seismic energy dissipation in planets . I : Fundamentals

Despite its broad acceptance, the viscoelastic model of anelasticity is problematic when applied to planetary deformations and seismology. This model presents the stressstrain responses phenomenologically, as time-dependent “material memory” or “intrinsic transient,” whereas in reality, they are controlled by the thermodynamic environments of deformation and spatial interactions. We describe rigorous physical approaches for the evaluation of the attenuation (damping) coefficients for planetary oscillations and seismic waves. Instead of the material memory and quality factor (Q), several specific mechanisms of mechanical-energy dissipation are recognized: 1) solid and pore-fluid viscosity, 2) thermoelasticity, 3) several types of kinetic processes, and 4) structural and scattering effects. Each of these processes leads to characteristic frequency dependences of the attenuation coefficients and apparent Q for various types of oscillations. Thermoelastic and kinetic processes can produce absorption peaks in Q, and scattering is also likely to produce the often-observed “high-frequency background” of Q decreasing with frequency. For solid viscosity, Q  , where  is the rheologic exponent of friction which is close to 0.5–0.63 for the Earth’s crust and mantle and ~1 for the core. A unified rheologic description for solids and fluids is proposed by using the Lagrangian formalism. This description explains the elastic-to plastic transition by the nonlinearity of the dissipation function and is consistent with seismic, tidal, lab, and geodynamic observations. Because of the interpreted near-dry friction within Earth’s materials, solid viscosity increases with temperature and decreases with pressure for near-elastic deformations but behaves oppositely for plastic deformations.
Starling1: Swarm Technology Demonstration

The Starling series of demonstration missions will test technologies required to achieve affordable, distributed spacecraft (“swarm”) missions that: are scalable to at least 100 spacecraft for applications that include synchronized multipoint measurements; involve closely coordinated ensembles of two or more spacecraft operating as a single unit for interferometric, synthetic aperture, or similar sensor architectures; or use autonomous or semi-autonomous operation of multiple spacecraft functioning as a unit to achieve science or other mission objectives with low-cost small spacecraft.
Effects of seed rhizome size on growth and yield of ginger cultivated using fertigation system

Ginger planting in Malaysia is usually carried out using shifting cultivation technique. This technique is practiced due to the infertile soils and the need to avoid soil-borne diseases that could infect the plant roots. Fertigation system could overcome the above problem and replaces the shifting cultivation technique, which is detrimental to the environment. Since the rhizome is the planting material, it is necessary to determine its suitable size and feasibility using this system. An experiment was conducted to study the influence of seed rhizome size on the growth and yield of ginger, thus determine an optimum seed rhizome size for the fertigation cultivation techniques. The study was conducted under rain shelter equipped with an irrigation system to supply fertiliser solution at a scheduled time. The study revealed that 1 g of rhizome seed yield fresh rhizome weight by 53 times after a nine-month cultivation period. It is concluded that the greater the seed rhizome size/weight, the larger is the fresh rhizome.
FARA : Framing Assembly Robotic Arm System for Construction Sites

The project aims to develop a manipulator type construction robot empowered with necessary sensors and software so that it can be controlled via manual control to survey the environment, conduct assembly work and avoid obstacles in the work site. An adaptation of Lynxmotion’s AL5D servo robotic arm is used to 3D-print a scaled model, and the motion of the robot is studied. Assembly of a 3D-printed model representation of a precast frame construction site is also presented. The manual control of the arm is fully achieved using an Xbox controller, coded with inverse kinematics. Further implementation of IR sensors mounted near the tool tip proves successful to detect obstacles. Additionally, a Microsoft Kinect motion sensor is utilized to provide surveying by using its RGB-D camera, and detecting workers on site to increase safety features. The findings indicate the feasibility of a full-scale Framing Assembly Robot Arm (FARA), as it would potentially reduce in-site casualties and lower the cost of labor.

Concurrent Algorithms for Emerging Hardware Platforms

of “ Concurrent Algorithms for Emerging Hardware Platforms ” by Irina Calciu, Ph.D., Brown University, May 2015 Computer architecture has recently seen an explosion of innovation that has enabled more parallel execution, while parallel software systems have been making strides in providing more simplified programming models. The number of computing cores used in every area of the software ecosystem continues to increase, and parallelism within programs is now ubiquitous. Ideally, performance would scale linearly with the number of cores, but that is rarely the case in practice. Communication and synchronization between cores running the same application are often necessary, but usually come at a high cost. This results in reduced scalability and a significant drop in performance. In this context, parallel software needs to provide more simplified programming patterns and tools that enable a higher potential for parallelism without increasing the burden on the programmer. This thesis discusses new techniques to simplify writing efficient parallel code by leveraging novel architectural features from many current systems. First, we describe various programming abstractions, such as delegation, elimination, combining and transactional memory, which improve scalability and performance of concurrent programs. Next, we show how to use and integrate these abstractions to write scalable concurrent algorithms, such as stacks and priority queues. Finally, we describe how to further improve these abstractions. In particular, we present new transactional memory algorithms that use Intel’s new extension to the x86 instruction set architecture, called Restricted Transactional Memory, to simplify general synchronization. Developers can use all of these abstractions as building blocks to create efficient code that is able to scale on very diverse platforms, with minimal specialized knowledge of parallel programming.
2 Preliminaries and Notation 2 . 1 Strings and Suffix Trees

We consider the problem of computing the q-gram profile of a string T of size N compressed by a context-free grammar with n production rules. We present an algorithm that runs in O(N −α) expected time and uses O(n+ q+ kT,q) space, where N −α ≤ qn is the exact number of characters decompressed by the algorithm and kT,q ≤ N−α is the number of distinct q-grams in T . This simultaneously matches the current best known time bound and improves the best known space bound. Our space bound is asymptotically optimal in the sense that any algorithm storing the grammar and the q-gram profile must use Ω(n+ q+ kT,q) space. To achieve this we introduce the q-gram graph that space-efficiently captures the structure of a string with respect to its q-grams, and show how to construct it from a grammar.
Oral Anticoagulant Treatment in Management of Elderly Patients with Atrial Fibrilation : Is It Benecial or Detrimental ?

Atrial brillation (AF) is supraventricular tachyarithmia characterized by uncontrolled atrial activation, and deteriorates atrial function. In AF patients, increasing of age is related with enlarge left atrium (LA), diminished ow velocity of left atrial appendage (LAA), and spontaneously contrast echo, with other factors which are predisposition for LA thrombus. In AF patients, thromboemboli after cardioversion without anticoagulant administration is 1.5-3.0%. Elderly patient is not contraindication for anticoagulant, although higher risk for bleeding. For stroke prevention in >65 years of age whilst the patient is candidate for oral anticoagulant warfarin, it should beprescribed to reach INR 2.0-3.0. Some reports on anticoagulant evaluation (INR) and bleeding as complication of warfarin prescribed for AF treatment are not signicantly different in elderly and younger patients.

Ultra fi ne Co-doped ZnO nanoparticles on reduced graphene oxide as an ef fi cient electrocatalyst for oxygen reduction reaction

In this work, we developed a novel hierarchical hybrid nanostructure of reduced graphene oxide (rGO) supported cobalt-doped ZnO nanoparticles (Co-doped ZnO NPs@rGO) via a simple solution-refluxing strategy. The ultrafine CoZn-glycolate nanoparticles precursor was obtained from the alkoxide reaction among ethylene glycol and Co/Zn ions absorbed onto GO support. The post-annealing process makes the precursor easily transferred into crystalline Co-doped ZnO NPs@rGO with well-retained morphology and the oxidation state of Co element to be Co in the final hybrid. When evaluated as an oxygen reduction reaction (ORR) electrocatalyst in an O2-saturated 0.1 M KOH solution, the Co-doped ZnO NPs@rGO hybrid with the optimal Co-doping concentration of 0.38 (i.e., Co0.38Zn0.62O NPs@rGO) exhibits highly enhanced ORR electrocatalytic activity compared to the ZnO@rGO composite with an ORR peak potential of 0.74 V (vs. RHE), an onset potential of 0.90 V, a current density of 3.94 mA cm 2 (at 0.4 V (vs. RHE)) and a nearly four-electron catalytic pathway. The good electrochemical stability and excellent methanol-tolerance capability of the resultant Co0.38Zn0. 62O NPs@rGO hybrid, superior to those of the commercial Pt/C catalyst, further demonstrate its great potential as an efficient ORR electrocatalyst. This work proposes the feasibility of the semiconducting ZnO nanomaterials as novel ORR electrocatalysts via doping active oxygen catalytic element, such as Co, for the first time. © 2016 Elsevier Ltd.

2 Spillover Effects from London and Frankfurt to Central and Eastern European Stock Markets

This paper investigates comovement in stock markets between the emerging economies of Central and Eastern Europe (CEE) and the developed markets of Western Europe. Three approaches are employed to examine this issue. The first two approaches, time-varying realised correlation ratios and cointegration statistics, use a two-step technique to derive timevarying estimates of the comovement between returns on CEE and EU stock exchanges. The first step uses common factor analysis to define the factors driving CEE stock exchanges, while the second step evaluates the relationship between the leading principal factor for CEE countries and the DAX and FTSE using time-varying realised correlation and rolling cointegration statistics. The third approach employs multivariate GARCH techniques to obtain estimates of mean and variance spillover effects.
anopy leaf area index for apple tree using hemispherical hotography in arid region

The hemispherical images of apple orchard were collected using fisheye lens in 2010 and then respectively analyzed by the methods of Bonhom, 2000, 2000G, sphere, ellipse, LAI 2000-3 rings, LAI 2000-4 rings and Miller to obtain leaf area index (LAI), plant area index (PAI), gap fraction, leaf inclination angle and clumping index in an arid region of northwest China. Results show that during DOY (day of year) 202–237 (at flourish stage), the estimated LAI by logarithmic ellipse method and PAI by LAI 2000-4 rings method were 1.96 and 1.95 m2 m−2, respectively, which were close to the direct LAI (1.85 m2 m−2). However, the direct LAI was higher than the estimated LAI from ellipse method of Hemiview (1.59 m2 m−2) and lower than the estimated PAI from gap fraction analysis method of Photoshop (2.67 m2 m−2). Thus the methods of logarithmic ellipse and the LAI 2000-4 rings were used to estimate the LAI (PAI) from hemispherical images. And the estimated LAI by the methods of logarithmic ellipse and the LAI 2000-4 rings were used to analyze seasonal variations of canopy parameters. LAI increased rapidly at leaf expanding eaf area index stage and then maintained at high level from the vigorous to harvest stage. Canopy gap fraction in the south side was similar to that in the north side. The leaf inclination angle tended horizontally to receive more radiation with the development of apple growth. In addition, the estimated LAI from hemispherical images using the methods of logarithmic ellipse and LAI 2000-4 rings was accurate even without calibrating clumping index. Thus the estimated canopy parameters from hemispherical images using the methods of logarithmic ellipse and LAI 2000-4 rings can be used for the modeling of evapotranspiration.
Secure and Private Function Evaluation with Intel SGX

Secure function evaluation (SFE) allows two parties to jointly evaluate a publicly known function without revealing their respective inputs. SFE can be realized via well-known cryptographic protocols, such as Yao's garbled circuits (GC) and the protocol of Goldreich, Micali, and Wigderson (GMW), which obliviously evaluate a Boolean circuit representation of the function. Unfortunately, even with the most recent optimizations that touch known lower bounds, these protocols incur an impractical high communication overhead. In this work, we efficiently realize SFE by evaluating the function in a trusted execution environment (TEE), concretely the widely available Intel Software Guard Extensions (SGX). We address the unresolved issue of countless software side-channel vulnerabilities in a unique way, namely by evaluating Boolean circuits - as used by cryptographic SFE protocols - inside an Intel SGX enclave. This way, all possible paths of the function are executed and all memory accesses are guaranteed to be independent of the actual input data. The communication of our protocol depends only on the number of inputs and outputs (it is optimal up to an additive constant), but not on the circuit size (in contrast to Yao's GC and the GMW protocol). Furthermore, we are the first to also address efficient private function evaluation (PFE) via TEEs, where one of the parties provides a function that represents intellectual property and is computed obliviously on the other party's input. For realizing PFE, we securely evaluate universal circuits (UCs) that can be programmed via input bits to emulate any function up to a given size. We provide a prototype implementation of our SFE and PFE protocols based on Intel SGX. We empirically compare its performance to the ABY framework (Demmler et al., NDSS'15) that provides state-of-the-art implementations of Yao's GC and the GMW protocol as well as an adapter for evaluating UCs. For PFE with a UC emulating a circuit with 10000 gates (representing, e.g., a secret function to calculate individual car insurance rates), we improve the run-time by factor 2.3x over Yao's GC and by at least two orders of magnitude over the GMW protocol in a high-latency Internet setting. The communication is reduced by factors 106x and 131x compared to Yao's GC and the GMW protocol, respectively.
HOLONOMICITY OF SPHERICAL CHARACTERS AND APPLICATIONS TO MULTIPLICITY BOUNDS

In this paper, we prove that any spherical character of any admissible representation of a real reductive group G with respect to any pair of spherical subgroups is a holonomic distribution on G. This implies that the restriction of the spherical character to an open dense subset is given by an analytic function. The proof is based on an argument from algebraic geometry and thus implies also analogous results in the p-adic case. As an application we give a short proof of the recent results of [KO13; KS] on boundedness and finiteness of multiplicities of irreducible representations in the space of functions on a spherical space. In order to deduce this application we prove relative and quantitative analogs of the BernsteinKashiwara theorem, which states that the space of solutions of a holonomic system of differential equations in the space of distributions is finite-dimensional. We also deduce that for every algebraic group G, the space of G-equivariant distributions on any algebraic G-manifold X is finite-dimensional if G has finitely many orbits on X .
