Rapid Prototyping of Embedded Microelectronics by Laser Direct-Write

For commercial, aerospace and military applications, miniaturization and functionality are key factors. In all these applications, the driving force is the need to achieve higher functionality in increasingly smaller volumes. As a result, traditionally packaged electronic components such as integrated circuits (ICs) and surface mount devices (SMDs) are reaching the point where their individual packaged size is too large to achieve the required device density on the available circuit board surface. There are various ways to address these limitations: for instance, application-specific ICs or ASICs, which eliminate the need for individual components, can be designed to replace an entire microelectronic circuit board. With ASICs, the entire circuit is fabricated in one fell swoop, and then packaged. However, development of these single-chip designs is costly and time consuming, and once their designs are completed, very difficult to change. In other words, none of the solutions currently available are capable of rapid prototyping customized circuits at a reasonable cost and in a limited amount of time. A better solution is to be able to place unpackaged devices and components inside the circuit board in order to achieve higher component densities. This approach, known as embedding, is used in some applications with passive devices, but has had limited success when applied to unpackaged or bare die semiconductor devices. This is because bare dies are very fragile and tend to be easily damaged by the robotic systems, known as "pick-and-place" tools, used to mount the devices on a circuit board. Furthermore, pick-and-place tools are ineffective when handling small or very thin ( 10 devices/sec). Therefore, the implementation of embedded electronic circuits comprising SMDs, interconnects and IC’s in bare die form promises to make possible levels of miniaturization well beyond the capabilities of current circuit manufacturing techniques. By burying or embedding the various circuit elements under the surface, significant reduction in weight and volume can be achieved for a given circuit board design. Embedded semiconductor bare dies are a good example of the advantages provided by this approach, since an embedded die occupies a fraction of the volume required by the same IC when packaged and wired using surface mount techniques. In order to realize these gains, novel approaches to the assembly and interconnection of embedded bare dies need to be considered. Laser direct-write processes and techniques, also known as LDW offer numerous advantages to the rapid prototyping of embedded microelectronic circuits (Pique & Chrisey, 2002a). Laser 12
Climate Variability And Its Local Perception And Adaptation Measures In Weliso Woreda, Ethiopia, East Africa

Climate variability (CV) is continued to cause greatest environmental, social and economic threats to mankind. Perception on the status of CV and its adaptive mechanism is the call of the day to come up with scientific recommendation for sustainable livelihood. The study assesses major features, of CV, and local perception on its features, causes, indicators and adaptation strategies in Weliso Wereda, Oromiya Regional State, Ethiopia. Three randomly selected kebeles are used where semi-structured interview with 180 sample household heads, 6 focus group discussions, 10 key informant interviews, and frequent field observations were conducted to collect primary data. Rainfall and temperature data of the last decade (from 2004 to 2013) used to understand CV. The finding of the study showed slight variability in temperature and rainfall. Local people perceived the prevalence of CV and also identified its indicators: flooding; drying up of rivers and streams, crop damage by pests; introduction of new human and animal disease; species shift to upper altitude, and introduction of new plant and animal species; rainfall variability in duration and amount; etc. They devised mechanical and biological conservation measures upon farm lands; watershed management; rain water harvest; changes in cropping pattern; growing short maturing crops; family planning and livelihood diversification as adaptation measures. Such endeavours are challenged by poverty and food insecurity, lack of access to land, water, market, finance, insurance, information, health, and agricultural technologies. This calls for improvement in agricultural production; capacity building on existing knowledge and practices of the people; training and awareness on rainwater harvesting technologies; strengthening access to social, institutional, financial, human and natural assets of livelihood, integrated watershed management, and sustainable environmental and livelihood development programmes.
Shallow-water caridean shrimps from southern Bahia, Brazil, including the first record of Synalpheus ul (Ríos & Duffy, 2007) (Alpheidae) in the southwestern Atlantic Ocean

In this contribution, we report 33 species of shallow-water marine and estuarine caridean shrimps from southern Bahia, Brazil. Nine taxa are reported for the first time from Bahia: the alpheids Alpheus cf. paracrinitus Miers, 1881, Alpheus cf. rostratus W. Kim & Abele, 1988, Automate cf. evermanni Rathbun, 1901, Leptalpheus aff. forceps Williams, 1965, Leptalpheus axianassae Dworschak & Coelho, 1999, Salmoneus carvachoi Anker, 2007 [previously reported as Salmoneus cf. ortmanni (Rankin, 1898)] and Synalpheus ul (Ríos & Duffy, 2007) (previously reported as Synalpheus cf. pandionis Coutière, 1909); the hippolytid Thor manningi Chace, 1972; and the processid Ambidexter symmetricus Manning & Chace, 1971. Synalpheus ul is reported for the first time in the South Atlantic Ocean, significantly extending its southern limit in the western Atlantic, and is illustrated herein. The presence of Alpheus bouvieri A. Milne-Edwards, 1878, A. cristulifrons Rathbun, 1900 and A. formosus Gibbes, 1850 in Bahia is confirmed. The southern range limit of the hippolytid Merguia rhizophorae (Rathbun, 1900) is extended from the Mamoã River, Ilhéus (14°35’05.6”S; 39°03’10.5”W) to Barra do Cahy, Prado (17°00’45.0”S; 39°10’21.0”W).
DMSP F7 observations of a substorm field‐aligned current

In this paper we present observations of a substorm field-aligned current (FAC) system that DMSP F7 traversed just after 0300 UT on April 25, 1985. Ground magnetometer data show that a major substorm was in progress at that time and that DMSP F7 flew through a region of predominantly upward FAC. The DMSP F7 magnetic field data are consistent with this interpretation. The precipitating particle data suggest that there were three distinct large-scale FAC systems. In ascending latitude these were a downward current, an upward current, and a paired upward/downward current system. We identify the first current, which was coincident with the diffuse aurora, as region 2. The next (upward) FAC was coincident with a spatially unstructured region of energetic (∼12 keV) electron precipitation. This was the substorm-associated FAC that made up part of the current wedge. The upward/downward current pair was coincident with a region of highly structured precipitation. We suggest that these currents may have been the duskside region 1 and, poleward of that, the extension of the dawnside region 1. The particle data show that the upward substorm current lay well equatorward of the boundary between open and closed field lines. In fact, using a model field, the equatorward boundary of the substorm FAC maps to the neutral sheet at 6.9 RE. While one should be cautious in stressing results obtained by mapping model field lines, our result is consistent with scenarios for substorms which postulate a disruption and diversion of the near-Earth cross-tail current.
Size Distribution Determination of Nanoparticles and Nanosized Pores by Small-Angle X-Ray Scattering ( SAXS ) on a Multi-Purpose X-Ray Diffractometer

This paper presents the small-angle X-ray scattering (SAXS) technique for the investigation of crystalline and amorphous materials on a length scale ranging from ca. 1 100 nm. We will focus on the characterization of nanopowder materials, nanocomposites and porous materials. Dry powders or dispersions of inorganic and organic nanoparticles can be characterized with respect to their particle size distribution, specific surface area and inner structure. In case of porous materials the specific inner surface area and pore size distribution may be determined. Compared to BET, TEM and light scattering techniques, the method is fast and no specific sample preparation is required. It has a very good precision, particularly so for very small particles and pores with a size below 10 nm. It will be demonstrated that such type of measurements are possible on a multi-purpose X-ray diffractometer platform with an option for automation in routine production control. Application examples for the characterization of photocatalytic nanoparticles, nanocomposties and porous nanopowders will be discussed.
Correlation-Based Feature Mapping of Crowdsourced LTE Data

There have been efforts taken by different research projects to understand the complexity and the performance of a mobile broadband network. Various mobile network measurement platforms are proposed to collect performance metrics for analysis. Data integration would provide more thorough data analyses as well as prediction and decision models from one dataset to another. The crucial part of the data integration is to find out, whether two datasets have corresponding features (performance metrics). However, finding common features across datasets is a challenging task. For example, features might: 1) have similar names but be different metrics, 2) have different names but be similar metrics, or 3) be same metrics but have differences in the underlying methodology. We designed a feature mapping methodology between two crowdsourced LTE measurement-based datasets. Our method is based on correlations between the features and the mapping algorithm is solving a maximum constraint satisfaction problem (CSP). We define our constraints as inequality patterns between the correlation coefficients of the measured features. Our results show that the method maps measurement features based on their correlation coefficients with high confidence scores (between 0.78 to 1.0 depending on the amount of features). We observe that mapping score increases as a function of the amount of features. Altogether, our results show that this methodology can be used as an automated tool in the measurement data integration.
Artifical potential fields with extended Bug algorithm for Mars rover path planning in an unknown environment

In this paper artificial potential fields method applied to autonomous mobile robot mars rover is presented. It is assumed that Mars rover operates in an unknown environment. In order to visualize the robot's path in environment Matlab software is used. The object can be inserted by graphic data input interface in top view mode. The method of artificial potential fields is extended by an additional algorithm to avoid a local minimum. The proposed algorithm is implemented as a state machine. In this paper simulations results of the developed algorithm are presented. Extended algorithm is used because in the environment may be located complex obstacles.
Hourly occupant density prediction in commercial buildings for urban energy simulation

Building occupant density is a key factor influencing urban energy consumption. However, it is difficult to predict and thus often simplified to be an assumed and fixed number in urban energy simulation. In this study, the hourly occupant densities of ten representative commercial buildings in Nanjing, China were measured. The pattern of the hourly occupant density was analyzed and the key parameters defining the pattern were identified. To expand the measured hourly occupant density pattern to thousands of commercial buildings in Nanjing, five predictors, namely function, accessibility, population, business diversity, business density, were proposed. Big data technique was used to obtain the value of the five predictors for more than 3000 commercial buildings. A regression analysis was conducted to establish a model linking the five predictors with the parameters defining the hourly occupant density pattern. The methodology developed provides an effective means to predict the hourly occupant density of buildings and thus substantially improves the accuracy and reliability of urban energy consumption.
Etch-and-Rinse and Self-Etch Adhesives Behavior on Dentin

Hybridization is a key phenomenon in bonding resin-based composite restorations to dentin, and results from a molecular-level interaction between the resin and the demineralized collagen fibrils network. Nanoleakage occurs when small molecules or ions infiltrate into the hybrid layer. Our work aims to evaluate if the type of solvent and adhesive system influences the morphology of the hybrid layer and the occurrence of nanoleakage within it. Human molar teeth were distributed into six groups corresponding to adhesives with different solvents (Scotchbond TM 1XT, XP Bond TM , Prime&Bond® NT, One Coat Bond®, AdheSE® and Xeno® V). Dentin disks (specimens) were cut from those teeth. The corresponding adhesive systems and a microhybrid composite (Synergy® D6) were applied onto them. The specimens were thermocycled, fixed, cut, polished, decalcified, dried, and, for nanoleakage evaluation, immersed into a tracer solution. The morphology and nanoleakage analyses were performed with a high- resolution scanning electron microscope (field-emission scanning electron microscope —FESEM), and the results were statistically processed. AdheSE® achieved the overall best performance. The type of adhesive, the number of steps, and the solvent seem to play a significant role in hybrid layer morphology and nanoleakage within it. The hybrid layer water absorption can determine the adhesion longevity.
Aalborg Universitet Decision support for blood glucose control in critically ill patients

Description: Hyperglycemia in intensive care patients is associated with increased mortality and prolonged illness. Tight blood glucose control reduces mortality and morbidity in some groups of critically ill patients, but increases the risk of hypoglycemia. Fear of hypoglycemia, and the required time and effort have yet prohibited tight blood glucose control to become a standard of care in intensive care units.
L'effet des aides à la R D sur l'emploi : une évaluation pour les petites entreprises en France

Between 2003 and 2010, the amount of tax incentives and subsidies granted by French public authorities to finance the R&D activities of SMEs increased fourfold. This very sharp increase is due to the research tax credit (RTC) reforms, particularly in 2008, the crea‐ tion in 2004 of a young innovative business status and an increase in subsidies over the period. Based on exhaustive employment data for France, this paper presents the first ever evaluation of the effect of the increase in these aids on small firms. Using a method that combines matching and a labour demand model, we show that the effect of public support on R&D employment is positive and increased during the period 2004-2010. Nonetheless, the increase in aid, particularly subsequent to the wide ranging reform of the RTC in 2008, was accompanied by a significant crowding-out effect: according to our estimates, only between 18 and 34% of the supplementary aid obtained by businesses between 2008 and 2010 was used to finance new jobs for highly qualified workers.

Latitudinal, seasonal, and small-scale spatial differences of the giant kelp, Macrocystis pyrifera, and an herbivore at their southern range limit in the northern hemisphere

Abstract Although several studies have described kelp-urchin interactions, little is known about these interactions toward the distributional range limits of these species in areas that may experience different physical conditions than at the center of the distributional range. We explored seasonal and latitudinal changes in the population structure of the giant kelp and the purple sea urchin at their southern limits in the northern hemisphere. Densities of both organisms were positively correlated, showing a significant effect of season and latitude, and were highest in the temperate kelp populations and in the spring. The near subtropical kelp populations, however, contained significantly larger urchins. Along the boundary between the kelp beds and the urchin barrens studied, no significant spatial difference was found in sea urchin size or density. However, a general pattern of increasing probability of urchin presence with distance outside of the bed was found in spring at all sites. Spring bottom temperatures were generally colder and more variable in the temperate kelp populations, potentially explaining the larger seasonal variability found there. Data suggest seasonal differences may be modulated by the environmental variability in the temperate kelp populations and support local coupling of these two organisms at their southern range limit, in spite of the particularly unique physical conditions which occur in these populations at times.
Field of Study, Qualification Mismatch, and Wages: Does Sorting Matter?

Graduates from Science, Technology, Engineering, and Mathematics (STEM) are usually found to have higher wages and a lower risk of overqualification. However, it is unclear whether we can interpret the effect of STEM subjects on overqualification and wages in a causal way, since individuals choosing these subjects might differ systematically in unobserved characteristics, such as ability. Using data on German male graduates we show that unobserved heterogeneity indeed matters for differences in the risk of overqualification and wages when STEM graduates are compared to the Business & Law group, while it plays only a minor role for the difference between STEM graduates and the Social Sciences & Humanities group.

ROAD RECOGNITION USING FULLY CONVOLUTIONAL NEURAL NETWORKS

In the past few years an increasing tendency is perceptible in the field of research and application of neural networks and deep learning. For image classification and segmentation convolutional neural networks are used intensively. Our goal is to solve the image recognition subsystem of a self-driving vehicle, which will take part in a competition. In order to fulfil this task fully convolutional neural networks were used. The present paper introduces an early-stage work for road recognition. In the current work-inprogress paper, the results are presented and further developments are discussed.
Fracture mechanics of early-age concrete

In this paper, the fracture mechanics of concrete structures is first reviewed. This clearly demonstrates that, despite the successful application of fracture mechanics to study the fracture behavior of mature concrete, its application to the cracking of very early-age concrete (i.e. within several hours after mixing) is still in its infancy, with very limited literature available. This is believed principally to be the result of difficulties that arise in the experimental determination of the properties of extremely fragile concrete at very early ages. In a recent research at the University of Queensland, a test apparatus and experimental procedures have been developed that enable the complete tensile stress-displacement behavior of concrete specimens at very early ages to be captured reliably. Based on the data obtained, the paper shows that current models for the stress-separation relationship of mature concrete may not apply for concrete at very early ages. Revised mathematical models for the stress-separation relationship of early-age concrete are proposed.
An Efficient Voice Based Person Identification System for Secured Communication

— Secured Communication is essential due to scalability due to increase number of devices and drastically growing number of people involved in communication. In this paper a voice comparison based communication authentication mechanism is used for providing secured communication. This voice based authentication is used in two different applications like people communication and data retrieval. Before going to speak with people in online their information and their voice is compared and verified from the database and permission will be granted. Similarly according to the voice they can retrieve the data from the data base, where it provides data integrity. Both applications comprise a number of stages such as: (i) Voice, Voice to Text input, (II). Voice Comparison and Pattern Matching. Finally (III). Permission Granted and Data Retrieval (DR) as the output. In order to improve the accuracy and relevancy the proposed data retrieval system, it uses an indexing method called Bag of Words (BOW). BOW is like an index-table which can be referred to store, compare and retrieve the information speedily and accurately. Index-table utilization in DRS improves the accuracy with minimized computational complexity. The proposed DRS is simulated in DOTNET software and the results are compared with the existing system results in order to evaluate the performance.
Pressure sources versus surface loads: Analyzing volcano deformation signal composition with an application to Hekla volcano, Iceland

The load of lava emplaced over periods of decades to centuries induces a gradual viscous response of the Earth resulting in measurable deformation. This effect should be considered in source model inversions for volcanic areas with large lava production and flow emplacement in small centralized regions. If deformation data remain uncorrected, constructive load and pressure source interference may result in an overestimate of depth and volume of a magma reservoir whereas destructive signal interference may cause these values to be underestimated. In both cases the source geometry preference could be biased. The ratio of horizontal and vertical displacements aids the identification of composite signals. We provide a method to quantify and remove the lava load deformation signals, using deformation at Hekla volcano, Iceland as an example.
