Analytical solutions for three-dimensional stability of limited slopes

A method of three-dimensional limited slope stability analysis is presented here based on the upper-bound theorem of the limit analysis approach. A rotating collapse mechanism is considered in which energy dissipation takes place along curve velocity discontinuities. In the frictional soils, the failure surface has the shape of logarithm helicoids, with track outline defined by log-spirals. In the cohesive soils, the shape of the failure surface is torus. Angle is considered at slope top, and the critical height is less than top with no inclination. Numerical results of the proposed algorithm are presented in the form of nondimensional graphs. Some examples illustrate the practical use of the results.

Applying the Metafounders Approach for Genomic Evaluation in a Multibreed Beef Cattle Population

Pedigree information is incomplete by nature and commonly not well-established because many of the genetic ties are not known a priori or can be wrong. The genomic era brought new opportunities to assess relationships between individuals. However, when pedigree and genomic information are used simultaneously, which is the case of single-step genomic BLUP (ssGBLUP), defining the genetic base is still a challenge. One alternative to overcome this challenge is to use metafounders, which are pseudo-individuals that describe the genetic relationship between the base population individuals. The purpose of this study was to evaluate the impact of metafounders on the estimation of breeding values for tick resistance under ssGBLUP for a multibreed population composed by Hereford, Braford, and Zebu animals. Three different scenarios were studied: pedigree-based model (BLUP), ssGBLUP, and ssGBLUP with metafounders (ssGBLUPm). In ssGBLUPm, a total of four different metafounders based on breed of origin (i.e., Hereford, Braford, Zebu, and unknown) were included for the animals with missing parents. The relationship coefficient between metafounders was in average 0.54 (ranging from 0.34 to 0.96) suggesting an overlap between ancestor populations. The estimates of metafounder relationships indicate that Hereford and Zebu breeds have a possible common ancestral relationship. Inbreeding coefficients calculated following the metafounder approach had less negative values, suggesting that ancestral populations were large enough and that gametes inherited from the historical population were not identical. Variance components were estimated based on ssGBLUPm, ssGBLUP, and BLUP, but the values from ssGBLUPm were scaled to provide a fair comparison with estimates from the other two models. In general, additive, residual, and phenotypic variance components in the Hereford population were smaller than in Braford across different models. The addition of genomic information increased heritability for Hereford, possibly because of improved genetic relationships. As expected, genomic models had greater predictive ability, with an additional gain for ssGBLUPm over ssGBLUP. The increase in predictive ability was greater for Herefords. Our results show the potential of using metafounders to increase accuracy of GEBV, and therefore, the rate of genetic gain in beef cattle populations with partial levels of missing pedigree information.
Efficient manufacturing technology for complex architecture

Finding a cost-efficient solution to create fluid, complex shapes has been the Holy Grail of architecture and engineering worldwide. Svelte uses a proprietary, unique, innovative machine system to generate all types of curved surfaces on an industrial scale, in one straightforward operation, at a fraction of the cost and time of current methods. Svelte works on a patented advanced cutting method using a heated SmartWire that changes its shape while moving through foam or wax-based materials to generate the desired surfaces.

Svelte disrupts the currently used CNC milling processes similarly to how 3D printers impacted the prototyping industry, pushing the boundaries of what is possible today to change architecture as we know it. A Svelte produced mould is at least 50% cheaper than a regular milled mould and has the ability to be mass produced in minutes, making the output of a single Svelte system equivalent to approximately 48 CNC machines. 

Svelte will therefore enable for the first time growth in the emerging special buildings niche to achieve the spectacular, innovative, energy efficient fluid forms of the future; but also generate substantial savings in the traditional building sector. Integrating Svelte cut shapes in existing building projects preserves their structural integrity, but uses up to 30% less construction materials, adding up to significant savings in energy, water, sand, CO2, coal, methane, NOX, and PM10 particles in Europe’s most polluting industry.

Having confirmed Svelte’s market acceptance and potential during the SME Instrument Phase 1 project, the focus is now on bringing the technology to TRL 9 during the proposed EIC project. In this scope we envision the optimization of the machine’s cutting function and prepare it for scaling to commence commercialization under both a FIAB model, but also as a SaaS solution producing moulds and panels in our own production facility.
Innovative technologies and concepts for fine particle flotation: unlocking future fine-grained deposits and critical raw materials resources for the eu

Froth flotation is arguably the most important mineral separation technique. By making use of differences in surface properties between  minerals, valuable particles are concentrated in large tanks by attaching to bubbles, which form a froth phase that overflows as a mineral-rich concentrate. However, current flotation technologies do not work adequately for fine particles, below 20 µm in size. This is a serious challenge at present limiting the exploitation of deposits and proper recycling of end of life products containing Critical Raw Materials (CRM). This FineFuture project will advance the fundamental understanding of fine particle flotation phenomena, which will lead to the development of ground-breaking technological solutions. This will not only help unlock new CRM deposits but also contribute to increase the resource and energy efficiency of current operations where the fines are lost to tailings. FineFuture will also enable proper reprocessing of old tailings deposits and be technology-transferred to other raw material particle-based processes within the circular economy, thus leading the way in the sustainable use of resources. For the EU industry the ability to float fine particles will be fundamental in securing access to raw materials in the future, yet to date there is no large scale collaborative effort to achieve this. The FineFuture consortium brings together an industry- and user-driven multidisciplinary team with the skills and experience required to tackle the challenging objectives set up for this project. Through a first of its kind research approach, the consortium’s combined expertise in science, engineering and industrial practice will allow a robust and knowledge-based development of innovative fine particle flotation technologies. This project will thus help boosting EU technologies for sustainable raw material processing in Europe and abroad, contributing to energy- and resource-efficient processing in benefit of the future generations.
Calipri - an easily customisable all purpose optical gauge for 2d-profiles.

CALIPRI Smart is a digital all-purpose measuring device for geometrical properties of arbitrary objects. The optical gauge outputs 2D profiles via WLAN and can be used for quality management and safety checks. The most important markets are railway companies and the automotive industry. The key of the innovation is the software of CALIPRI which allows high-precision measurements although the device is hand guided. This software can be adapted easily to the individual needs of the customer. Hence one and the same handheld gauge can be sold as custom-made device, optimized for the applications of the user. The customising is done by a setup assistant software and needs only a minimum of personnel costs. In opposite to devices, which use a hardware developed for a certain niche application, CALIPRI is a universal solution. This allows a high quantity and low unit cost in production. The customisation is the low-cost part of the product and so it is possible to produce niche products at the quantity and price of a mass product. 
NextSense plans to conquer the international markets with CALIPRI. The competitive price in combination with customised solutions makes an excellent price-performance ratio and provides the opportunity to become the global market leader. NextSense already built up an international distribution network in Europe and Asia. Today most of the customers are railway companies and the automotive industry. In this project, NextSense will find a feasible strategy to conquer the rest of the industrial nations and to enter in new industrial sectors like aerospace, shipyards, household appliance and machine tools. The feasibility study will cover an investment plan, subsidies, HR and marketing efforts. The new organizational company structure and the required financing strategy will be developed. The final result will be a business plan including a schedule of capturing different international regions, an investment plan and a budget plan.
Two-wire type remote control system and display device

A receiver side of a two-wire type remote control system accurately determines the polarity of data. The reception buffer inverts an input from one of the data and electric communication lines, and adds the inverted input to an input of the other line. Then, when the result of the addition is 0 or close to 0, the reception switches buffer logic data to be output to indicate the inversion of the level of the equilibrium pulse-like power received from the communication lines. The polarity identifying portion identifies the polarity when the logical data sent from the reception buffer is maintained at a logic level for a predetermined period of time. The polarity identifying portion sends pulse group data to the data processing portion in accordance with the identified polarity.
Efficient Spam Filtering System Based on Smart Cooperative Subjective and Objective Methods

Most of the spam filtering techniques are based on objective methods such as the content filtering and DNS/reverse DNS checks. Recently, some cooperative subjective spam filtering techniques are proposed. Objective methods suffer from the false positive and false negative classification. Objective methods based on the content filtering are time consuming and resource demanding. They are inaccurate and require continuous update to cope with newly invented spammer’s tricks. On the other side, the existing subjective proposals have some drawbacks like the attacks from malicious users that make them unreliable and the privacy. In this paper, we propose an efficient spam filtering system that is based on a smart cooperative subjective technique for content filtering in addition to the fastest and the most reliable non-content-based objective methods. The system combines several applications. The first is a web-based system that we have developed based on the proposed technique. A server application having extra features suitable for the enterprises and closed work groups is a second part of the system. Another part is a set of standard web services that allow any existing email server or email client to interact with the system. It allows the email servers to query the system for email filtering. They can also allow the users via the mail user agents to participate in the subjective spam filtering problem.
Full-term newborns with normal birthweight requiring special care in a resource-constrained setting

The level of clinical care and facilities to support the often more viable full-term newborns with normal birth weight compared with preterm/low birth weight newborns that require special care at birth are likely to be attainable in many resource-poor settings. However, the nature of the required care is not evident in current literature. This study therefore set out to determine maternal and perinatal profile of surviving full-term newborns with normal birth weight in a poorly-resourced setting.A retrospective cohort study of newborns with gestational age ≥37 weeks and birth weight ≥2500g recruited in an inner-city maternity hospital in Lagos, Nigeria. Primary factors/outcomes were determined by multivariate logistic regression analyses and population attributable risk (PAR).Of the 2687 full-term newborns with normal birth weight studied, 242 (9.0%) were admitted into special care baby unit (SCBU) representing 53.6% of all SCBU admissions. Fetal distress, low 5-minute Apgar scores, neonatal sepsis and hyperbilirubinemia as well as maternal factors such as primiparity, type of employment, lack of antenatal care and emergency cesarean delivery were predictive of SCBU admission. The leading contributors to SCBU admission were neonatal sepsis (PAR=96.8%), and hyperbilirubinemia (PAR=58.7%).A significant proportion of newborns requiring special care are full-term with normal birth weight and are associated with modifiable risk factors that can be effectively addressed at appropriately equipped secondary-level hospitals. Prenatal maternal education on avoidable risk factors is warranted.
An improved method of and means for compensating for wear in driving chains

187,042. Nuttall, P. July 21, 1921. Rivet and bush extractors.-The pitch of worn chains is restored by turning the pins and bushes to bring unworn parts thereof into bearing contact. A roller chain is secured upon a support by teeth 2, 3, 4 engaging between the rollers, and by a wedge pin 6 inserted through an aperture in the tooth 3. The narrow ends of stepped plungers 16 are pressed against two chain studs by a screw 13 to force them out of one of the outer link plates. These plungers are then withdrawn and corresponding plungers 18 actuated from the opposite side of the chain to free the second outer link plate. The plungers abut against plates 24 slidable upon rods 11 which carry slides 9, 10 wherein the plungers are slidable and rotatable. The slides can be pressed towards the chain by reduced ends 14 of the screws 13, and the plates 24 are similarly actuated by the main body of the screws. After freeing the outer link plates, the studs are held between the opposing plungers and these are turned together with the studs by handles 21, 23. Packing pieces 27, 28 are then removed from behind the plate 24 of the slide 10, which allows this to be advanced, without moving the plungers, to replace one outer plate upon the turned studs. These connected studs and link plate are then removed from the chain, and the adjacent inner link plates are operated upon similarly, but by the wider parts of the plungers, to remove, turn, and replace the bushes. The connected studs and outer link plate are then replaced, and the remaining outer link plate forced on to the studs. To enable " silent " chains to be operated upon, they are secured by screws 52 upon holders 47 shaped as shown in Fig. 7. Interchangeable chain-holders may be clamped between the opposing halves 7, 8 of the bed of the apparatus.
Gotam cities - geography of talents in metropolitan cities

In the context of a growing knowledge economy the competitiveness of global cities is crucially affected by their ability to nurture and attract talented workers. In this global race the European Union is lagging behind in comparison with the US and other Anglo-Saxon economies. The diffusion of anti-immigration sentiments is also worrisome because the recovery from the Great Recession of 2008 is far from being in sight for many EU regions while the access to a diverse set of skills via high skilled immigrants could boost the innovative sectors needed for economic growth. Therefore it is important to provide robust evidence on the economic effects of High Skilled Immigration (HSI) in order to justify policies for their attraction. 
GOTaM cities aims at understanding how talents are attracted to cities and how they impact on their innovative performance and prosperity. While building on existing literature the project will make several contributions by addressing some unexplored questions and empirical shortcomings: 
a. GOTaM will focus on HSI in different geographical contexts (i.e EU, US, China and Brazil): the existing evidence is biased towards the US which leaves a lack of understanding about HSI in other areas;
b. It will use individual data and focus on city/region level effects: most empirical literature relies on aggregate data at country level; 
c. It will investigate the qualitative effects of migration: whether HIS enhances the technological and economic diversification of cities by bringing new knowledge to those places;
d. It will build a unique comprehensive dataset (and related methodologies) on migrant inventors and scientists which will help the scholarly community and policy makers to carry out informed empirical analysis: the findings so far are disputed also because carried out on specific cases or ethnic groups (e.g. Russian mathematicians);
The findings of GOTaM will serve as a basis for inspiring new and more effective immigration policies.
Advanced integration of fluid dynamics and photosynthetic reaction kinetics for microalgae culture systems

Photosynthetic microalgae have been in the spotlight of biotechnological production (biofuels, lipids, etc), however, current barriers in mass cultivation of microalgae are limiting its successful industrialization. Therefore, a mathematical model integrating both the biological and hydrodynamical parts of the cultivation process may improve our understanding of relevant phenomena, leading to further optimization of the microalgae cultivation.We introduce a unified multidisciplinary simulation tool for microalgae culture systems, particularly the photobioreactors. Our approach describes changes of cell growth determined by dynamics of heterogeneous environmental conditions such as irradiation and mixing of the culture. Presented framework consists of (i) a simplified model of microalgae growth in a culture system (the advection-diffusion-reaction system within a phenomenological model of photosynthesis and photoinhibition), (ii) the fluid dynamics (Navier-Stokes equations), and (iii) the irradiance field description (Beer-Lambert law). To validate the method, a simple case study leading to hydrodynamically induced fluctuating light conditions was chosen. The integration of computational fluid dynamics (ANSYS Fluent) revealed the inner property of the system, the flashing light enhancement phenomenon, known from experiments.Our physically accurate model of microalgae culture naturally exhibits features of real system, can be applied to any geometry of microalgae mass cultivation and thus is suitable for biotechnological applications.
Optical system for the automatic alignment of two motifs comprising alignment marks of the grating type, particularly in direct photorepetition on silicon

Optical system for the automatic alignment of two motifs in which the alignment marks of a first fixed motif forming the reference are constituted by at least one pair of identical periodic optical gratings with a constant spacing P and having a predetermined distance dX from one another such that the equation dX=(n+ epsilon ) P is proved, n being an integer and epsilon a fraction of unity. An optical modulator, for example electro-optical means incorporating a Pockels cell alternately illuminate with the timing of the high frequency control signals, the said gratings in windows, whose position can be regulated in accordance with a given axis. The image of these windows is projected onto gratings carried on a second moving support to be aligned and produces orders of diffraction. An optoelectronic detector detects a predetermined order of diffraction. The high frequency-modulated output signals are transmitted to control circuits for producing the automatic alignment.

Highly Diastereoselective Samarium Diiodide Induced Ketyl Cyclisations of Indole and Pyrrole Derivatives - Scope and Limitations

Here we summarise our results for SmI2-induced 5-exo-trig to 8-exo-trig reductive cyclisations of suitably substituted indole and pyrrole derivatives. All precursors were easily prepared by simple N-alkylation or N-acylation of indole and pyrrole derivatives with the corresponding iodo alkanones, acid chlorides or lactones. The SmI2-induced cyclisations in most cases provided tri- and tetracyclic derivatives, even in the absence of HMPA, in good to very good yields and with excellent diastereoselectivities. Extensive investigations of the reaction conditions revealed that in the presence of different proton sources SmI2-induced cyclisations afforded mainly one major type of diastereomer (thermodynamic control), so the formation of three or four stereogenic centres is controlled in one step. The mechanism of the SmI2-induced ketyl coupling is discussed in more detail on the basis of these observations and two possible mechanistic pathways are compared. The assumed intermediate samarium enolates were also trapped with allyl iodide, furnishing interesting polycyclic N-heterocycles bearing newly formed quaternary centres as single diastereomers.
