"Quantificazione automatica di spettri 1H ed estrazione di mappe metaboliche da acquisizioni CSI mediante Wavelet Packets." Rivista di Neuroradiologia 13, no. 1 (February 2000): 31–36. http://dx.doi.org/10.1177/197140090001300106.
Full textAbstract:
La quantificazione dei picchi spettrali del segnale di spettroscopia 1H in risonanza magnetica, utile per un'analisi metabolica dei tessuti in-vivo, richiede un tempo di elaborazione elevato, soprattutto quando si tratta di acquisizioni CSI dove ad essere elaborata è un'intera matrice di dati. Inoltre, la sovrapposizione dei picchi, maggiormente marcata negli spettri con tempo di eco breve (20 ms), rende spesso difficoltosa la separazione dei singoli contributi metabolici. Si propone pertanto un metodo automatico per la quantificazione dei metaboliti, che utilizza l'algoritmo delle Wavelet Packets per scomporre il segnale nel dominio del tempo (FID) in sottobande. La stima dei parametri di ampiezza, fase, frequenza e smorzamento viene quindi eseguita nelle sottobande, dove cadono i picchi di interesse, mediante metodi di predizione lineare basati sulla scomposizione a valori singolari (LPSDV). L'ampiezza stimata dei picchi viene infine utilizzata sia per il calcolo dei rapporti metabolici sia per l'estrazione di mappe metaboliche. Il metodo di quantificazione proposto è stato messo a punto su fantocci e poi applicato alle acquisizioni di volontari sani e infine su alcuni pazienti. L'elaborazione automatica dei dati spettroscopici con il metodo proposto offre la possibilità di studiare in modo efficace ed affidabile i metaboliti cerebrali nonché di rappresentare la loro distribuzione spaziale mediante mappe metaboliche.

Il contributo descrive un approccio metodologico basato sull'integrazione dei servizi ecosistemici a supporto del processo di pianificazione territoriale del Piano di governo del territorio (pgt) del Comune di Romano di Lombardia. Tale approccio si fonda sulla considerazione del ruolo di questi servizi in ogni fase del percorso di piano/valutazione ambientale strategica (vas), dallo scoping alla stima degli effetti, alla definizione di criteri attuativi. I servizi ecosistemici sono stati caratterizzati elaborando dati spaziali provenienti da banche dati pubbliche o costruendo mappe originali con la collaborazione dei cittadini. L'analisi dello stato dei servizi ecosistemici e la stima della variazione del grado di erogazione degli stessi a seguito dell'attuazione delle previsioni di piano hanno costituito il contributo della vas alla sostenibilità delle scelte di piano.

Abstract The article presents the current topic of the possibility of mechanical extraction of hard and abrasive rocks using mechanized wall systems. The problem of extracting ores from thin strata precludes the possibility of further use of current technologies involving a human at the face. Currently, the operation is carried out using explosives in column-pillar systems. In systems with a chamber column, all major processes are mechanized and carried out by self-propelled drilling and bolting machines, loaders as well as hauling and auxiliary trucks. These machines are operated in the workplace by operators. For many years, effective mechanical excavation methods were sought that would allow the development of a mining machine and a mechanised longwall complex. Such a complex is to allow excavation without the presence of humans at the face. The article presents the current technical capabilities, assumptions and requirements for such a solution. Then, an innovative longwall complex equipped with a disc shearer is introduced. The technology of work and achievable productivity are briefly presented. A worn shearer, a face conveyor and a powered support are the subject of AGH inventions.

Abstract In current conditions, great attention is paid to the quality of parts, which is in many ways determined by finishing operations of mechanical treatment, with surface grinding being the most widespread. Grinding process efficiency, abrasive tool wear intensity, machined surface quality and other features of grinding process depend on properties of the environment, where the cutting process takes place. Forced changing of conditions of this environment is one of the ways to control and optimize the grinding process, which can be reached due to finding new technological decisions. One of the most promising directions to solve this problem is the process of face grinding with discontinuous grinding tool and supply of cooling fluid or air in the cutting zone directly. Carried analysis of features of face grinding has shown that heat density can be decreased by the usage by grooved wheels with vortex air cooling or by supply of cooling-lubricant technological fluid. Obtained dependences of temperature field of part surface during grinding establish the influence of the length of working shoulders and grooves, vortex tubes number, outflow rate, temperature and flow rate of cold vortex flow of air. These data provide conscious control over the process of discontinuous face grinding by changing wheel grain size and grinding speed.

Objective. The aim of this study was to determine if the use of different mappers for NIPT may vary the results considerably. Methods. Peripheral blood was collected from 217 pregnant women, 58 pathological (34 pregnancies with trisomy 21, 18 with trisomy 18, and 6 with trisomy 13) and 159 euploid. MPS was performed following a manufacturer’s modified protocol of semiconductor sequencing. Obtained reads were mapped with two different software programs: TMAP and HPG-Aligner, comparing the results. Results. Using TMAP, 57 pathological samples were correctly detected (sensitivity 98.28%, specificity 93.08%): 33 samples as trisomy 21 (sensitivity 97.06%, specificity 99.45%), 16 as trisomy 18 (sensibility 88.89%, specificity 93.97%), and 6 as trisomy 13 (sensibility 100%, specificity 100%). 11 false positives, 1 false negative, and 2 samples incorrectly identified were obtained. Using HPG-Aligner, all the 58 pathological samples were correctly identified (sensibility 100%, specificity 96.86%): 34 as trisomy 21 (sensibility 100%, specificity 98.91%), 18 as trisomy 18 (sensibility 100%, specificity 98.99%), and 6 as trisomy 13 (sensibility 100%, specificity 99.53%). 5 false positives were obtained. Conclusion. Different mappers use slightly different algorithms, so the use of one mapper or another with the same batch file can provide different results.

Abstract In hard coal mines with methane, there is often a need to apply demethylation in order to keep the methane concentration not exceeding 2% in the ventilation air. The basic demethylation method in longwall areas is through drainage boreholes made in the roof rocks of the coal bed, from top gate, in front of the longwall. The drainage boreholes are usually made in bundles, in a fan-shaped arrangement, with several boreholes in each bundle. The paper presents the results of measurements and tests of the efficiency of a bundle of four drainage boreholes drilled approximately 100 m in front of the longwall face. The efficiency of individual boreholes was analyzed in time and depending on the distance of borehole outlets from the longwall face. It was found that there is a large variation in the extraction of air-methane mixture by individual drainage boreholes, as well as large differences in the efficiency of individual drainage boreholes during the longwall extraction process.

Full textAbstract:
AbstractTwo Geostationary Lightning Mappers (GLMs) now observe spatial and temporal lightning distributions over a vast region. The GOES-16 GLM covers most land areas in the Western Hemisphere, and detects ~4 times as much lightning as the GOES-17 GLM. Although the continents dominate the lightning distributions year-round, each season exhibits widespread lightning over parts of the Atlantic Ocean and within three broad regions over the Pacific. These oceanic regions demonstrate the key role convective organization plays in producing larger, longer-lasting, and more energetic flashes observed by both GLMs over the oceans. Texture within the flash densities reveals a close relationship with the underlying topography, underscored by the complex diurnal cycles observed along coastlines and in mountainous regions. GLM information beyond flash frequency provides additional insights into storm mode and evolution. For example, over the Sierra Madre Occidental, time series reveal initially small, short-duration GLM flashes growing larger and longer as storms grow upscale. These mesoscale convective systems often transition offshore, contributing to an average flash area maximum over the eastern Pacific. Data quality improves during the study period with tuning of the ground system software. GLM artifacts due to solar intrusion and sun glint greatly diminish following the blooming filter installation, and the second-level threshold filter reduces false events along particular subarray boundaries (i.e., bar artifacts). Analysis of the overlap region reveals a pronounced north–south line near 103°W, with the GOES-16 (GOES-17) GLM detecting more flashes to the east (west) of this line.

Abstract Making decisions is a process that involves taking into account n acceptable variants of undertaken actions in view of m adopted assessment criteria and selecting the optimal variant (optimal variants). Due to the number of alternatives being assessed and the number of considered criteria, more and more frequently mathematical methods are used in this process. Basing on the example involving the selection of a mechanized longwall complex, the article presents the application of selected multicriteria methods: in the case of quantitative features – Hellwig's development measure method, and in the case of qualitative features – Promethee II method. In the case of Hellwig's development measure method, equipment variants were interpreted as points w in the multidimensional space, and then the distances between them and the point Po (perfect solution) were determined. In the case of the Promethee II method (discrete multicriteria decision support method), the equipment variants were compared with each other in pairs, which made it possible to determine the so-called net flows Φ(i). The obtained synthetic values mi and Φ(i) allowed to build rankings of equipment variants (objects) and to indicate the optimal variant.

Full textAbstract:
The magnitude associated with a stimulus can be spatially connoted, with relatively smaller and larger magnitudes that would be represented on the left and on the right side of space, respectively. According to recent evidence, this space–magnitude association could reflect specific brain asymmetries. In this study, we explored whether such an association can also emerge for face age, assuming that responders should represent relatively younger and older adult faces on the left and on the right, respectively. A sample of young adults performed a speeded binary classification task aimed at categorising the age of a centrally placed adult face stimulus as either younger or older than the age of a reference face. A left-side and a right-side response key were used to collect manual responses. Overall, older faces were categorised faster than younger faces, and response latencies decreased with the absolute difference between the age of the target stimulus and the age of the reference, in line with a distance effect. However, no evidence of a left-to-right spatial representation of face age emerged. Taken together, these results suggest that face age is mapped onto space differently from other magnitudes.

Abstract Companies are increasingly implementing sustainable solutions as they face a growing sustainability demands from different stakeholders. The question is whether car manufacturers adhered to sustainable production principles and at what level they are doing it in practice. The Lowell Center for Sustainable Production (LCSP) is used as a model to analyse the main aspects of sustainable production and assess the companies in the automotive sector in European Union. The data was collected from the Corporate Social Responsibility/ Sustainability reports of the individual car manufacturers found in the online data base of Global Reporting Initiative. Empirical evidence shows the adherence of these companies to the LCSP sustainable production principles. All the studied companies seem to be conscious of the significance of sustainability for the automotive industry. Although most of the sustainable production practices are focused on the environmental dimension of sustainability, employee and social aspects are not ignored in the reports.

Accurate measurement of poses and expressions can increase the efficiency of recognition systems by avoiding the recognition of spurious faces. This paper presents a novel and robust pose-expression invariant face recognition method in order to improve the existing face recognition techniques. First, we apply the TSL color model for detecting facial region and estimate the vector X-Y-Z of face using connected components analysis. Second, the input face is mapped by a deformable 3D facial model. Third, the mapped face is transformed to the frontal face which appropriates for face recognition by the estimated pose vector and action unit of expression. Finally, the damaged regions which occur during the process of normalization are reconstructed using PCA. Several empirical tests are used to validate the application of face detection model and the method for estimating facial poses and expression. In addition, the tests suggest that recognition rate is greatly boosted through the normalization of the poses and expression.

Abstract This article presents structure and analysis of possible events for information security of a production company. The aim of the analysis is to identify incident events, their time and frequency. The analysis includes occurrence of notifications, threatening events, employee errors and false alarms. Also, the conducted research takes into account the functions performed in the enterprise. For these events, a daily distribution of events and statistical analysis of their occurrence were developed. Thanks to the analysis of the phenomena in time, enterprises can introduce actions preventing the occurrence of incidents. The conducted research has shown that employees report incidents which, in their opinion, constitute an incident, which greatly facilitates the work of the information security administrator. These events are analyzed and classified accordingly. The analysis showed that most events take place between midnight and two in the morning. The conducted analysis is a pilot study carried out in one large enterprise in the metallurgical industry.

AbstractThe construction phase of oil and gas projects (OGPs) is a risky process and project managers face numerous challenges during this particular period. A proper risk analysis and management during the construction phase of the OGPs not only will affect the timely and successful operation of the project as a whole, it can also affect occurrence of risks in subsequent phases and overall economic viability of the project. As a result, via using extensive literature review, this study tries to answer the question of what are main risks involved in construction phase of OGPs and which methods are used for identifying them? The outcome of this research would likely be a valuable source for construction professionals to improve project performance while managing existing risks. It is also useful to avoid common problems that befall many project managers and will assist them to have a better understanding of risk management as part of a project plan.

The computational cost of kernel discrimination is usually higher than linear discrimination, making many kernel methods impractically slow. To overcome this disadvantage, several accelerated algorithms have been presented, which express kernel discriminant vectors using a part of mapped training samples that are selected by some criterions. However, they still need to calculate a large kernel matrix using all training samples, so they only save rather limited computing time. In this paper, we propose the fast and effective kernel discriminations based on the mapped mean samples (MMS). It calculates a small kernel matrix by constructing a few mean samples in input space, then expresses the kernel discriminant vectors using MMS. The proposed kernel approach is tested on the public AR and FERET face databases. Experimental results show that this approach is effective in both saving computing time and acquiring favorable recognition results.

Abstract When a new EU directive on municipal waste management was implemented in Poland over 5 years ago, there were practically no IT systems on the market allowing for comprehensive support of this process. Significant changes revealed a number of problems that the municipalities had to face and are facing today, trying to create an integrated system of waste management. IT systems used by municipal units before the amendment of the act have been proved insufficient to be able to efficiently manage the collection of waste from residents. The new regulations significantly influenced, among others, the process of information flow between entities in the waste management system. New participants in the municipal waste management process have been introduced, which from that moment has had to be dealt with by municipal units - the entire organization of the waste collection process and information activities in this area fell on the municipalities. This article presents the results of research on IT systems used in municipalities and its needs in this area. These surveys were carried out using a questionnaire sent to municipalities in the Silesian Voivodeship. Its aim was to identify the features and functions that should be met by the IT system, allowing for comprehensive management of the new municipal waste management system.

Full textAbstract:
Abstract Unscheduled downtimes in machine operation are one of the main reasons behind their low availability. Such downtimes are caused by miscellaneous factors and remain difficult to identify in a number of cases. This particularly refers to enterprises that conduct their activities in changing external conditions, such as hard coal mines, where exploitation is carried out in extremely complicated, changeable and dangerous conditions. The process of coal production makes use of various machines that must be adapted to these conditions. The specificity of the working environment makes it necessary for these machines to exhibit high reliability, readiness and efficiency. These features, in turn, make the cost of the machines very high. It is therefore reasonable to make the best use of their capabilities, which translates into the effectiveness of the entire production process. The article concentrates on determining the availability of these machines. It has been assumed that availability is one of the fundamental parameters that define the effective utilisation of machines. The tests were conducted for a longwall shearer as well as an armoured face conveyor and a main haulage conveyor in one of the hard coal mines in Poland. Industrial automation systems were used to determine unscheduled downtimes in the operation of these machines, as well as their time structure and causes. The results obtained indicate that the number of unscheduled downtimes represents a serious problem in mining exploitation.

Abstract The roof support, especially the ŁP yielding steel arch support, is transported and assembled in the face with the use of auxiliary machines. This activity in Polish underground mines causes numerous problems, which until present have not been solved. Currently, transport and assembly are carried out manually, while the roadheader and suspended rail are used only to a small extent. Therefore, the modular installation and transport assembly was developed jointly by FAMA Sp. z o. o. and AGH University of Science and Technology. The solution in question enables performing a number of functions (including transport and assembly of all kinds of support arches), which are not available in currently manufactured equipment. The proposed manipulator solves numerous problems occurring during the installation of the steel arch support in an underground mining excavation and significantly improves the process of drilling galleries. This innovative solution considerably differs from the existing ones, and its greatest advantage is versatility with regard to the cross-section and equipment of the roadway, as well as a wide range of functions. In addition, it can also be used for reloading works. The modular installation and transport assembly together with a platform, a temporary mechanized roof support and a mining machine, make up a mechanizes roadheader complex, which enables continuous mining, loading and installing the permanent support in underground workings.

Local feature description forms an integral part of texture classification, image recognition, and face recognition. In this paper, the authors propose Center Symmetric Local Ternary Mapped Patterns (CS-LTMP) and eXtended Center Symmetric Local Ternary Mapped Patterns (XCS-LTMP) for local description of images. They combine the strengths of Center Symmetric Local Ternary Pattern (CS-LTP) which uses ternary codes and Center Symmetric Local Mapped Pattern (CS-LMP) which captures the nuances between images to make the CS-LTMP. Similarly, the auhtors combined CS-LTP and eXtended Center Symmetric Local Mapped Pattern (XCS-LMP) to form eXtended Center Symmetric Local Ternary Mapped Pattern (XCS-LTMP). They have conducted their experiments on the CIFAR10 dataset and show that their proposed methods perform significantly better than their direct competitors.

Abstract The Europe 2020 strategy (European Commission, 2010) calls a bioeconomy as a key element for smart and green growth in Europe. The development of a greener and more resource-efficient economy gives rise to new technologies and materials, which in turn may result in increased exposure to biological agents or combinations of different potentially harmful factors. For example, the expanding recycling industry employs an increasing number of workers which have to face various health problems (pulmonary, gastrointestinal and skin problems) as a result of exposure to biological agents such as airborne microorganisms. However, specific numbers for occupational diseases in this sector are still lacking. There are various workplaces and professional activities especially from the green industry for which exposure to microbiological agents occur unexpectedly and in an uncontrolled way. The issue of uncontrolled microbial exposure there is for example in waste treatment and for retrofitting activities, both growing sectors of employment in a greening society. As a result of the problem in the green industrial sector, there is a need to develop tools for risk assessment and prevention measures. In order to be able to develop suitable risk management strategies, a further development of detection and identification methods for biological agents is needed to cover the whole spectrum of microorganisms. the present paper focuses on the microbiological risk assessment in the context of the development of new and safe industrial products and processes of green industry (bioindustry and bioprocessing).

Abstract In underground mines, where the deposit is located at considerable depths, mining shafts are key excavations. The project of making the deposit available requires selection of appropriate shaft sinking technology adapted to geological and hydrological conditions and natural hazards. Shafts can be made using the classic drilling and blasting technique or mechanical cutting of the shaft face. Mechanical cutting requires the use of a mining machine, which together with machines for loading and hauling the output and protecting the side walls is a shaft complex. Drilling using mechanized shaft complexes allows for high efficiency and work safety. To improve the efficiency of drilling, it is particularly important to implement many processes in parallel. The article presents an analysis of the progress of shaft sinking with a mechanized complex as a function of technical and organizational parameters. The analysis concerned a new generation cutting shaft complex, developed for the needs of shaft sinking for one of the Polish hard coal mines. The calculations were carried out for a shaft with a maximum diameter of 9.5 m and a total depth of 830 m. The article briefly presents a new solution for the shaft complex. There are presented results of calculations of daily drilling progress and total time of shaft sinking for the developed working technology of this complex. The efficiency of the complex depends on many factors related to technical parameters of individual machines and devices forming the complex and organizational parameters, hence a multi-variant analysis was carried out.

The COVID-19 era has forced us to reduce our face-to-face interactions. For this reason, Information and Communication Technologies (ICTs) have substituted this direct relationship among people. One tool able to support health authorities by monitoring and mitigating the ongoing COVID-19 is Mobile Applications (mApps). They have also facilitated follow-up among patients and practitioners and provided direct guidance to citizens, so they can play their part in the control of the disease. The main purpose of this paper is to understand and analyse the features and functionalities of the COVID-19 mApps currently available in the widely used smartphone applications stores, such as Play Store and iTunes. The first results obtained at this stage of the research have permitted us to give a preliminary taxonomy of the mApps, specifically concerning COVID health management in Italy. The research found 71 mApps operating in the principal stores, focusing on the underlining features and aspects useful for making users more responsible and enabling self-management regarding their own health. MApps in the COVID period could represent organisational support for maintaining a useful relationship among patients and health operators concerning health care assistance. To do this, it is necessary to determine optimal capabilities and evaluate the utility and clinical benefit of these tools. Doing this, we have been able to recognise and obtain the first data and information through this research.

Full textAbstract:
Mental health problems contribute 23% to the global burden of disease in developed countries (WHO, 1999). In the U.K., recent legislation attempts to address this by modernizing mental health services so that they provide evidence based, accessible and non-discriminatory services for both serious and common mental health problems. Cognitive behaviour therapy (CBT) has a robust evidence base that fits very well with the thrust of policy. However, CBT's delivery systems are rooted in traditional service models, which pay little attention to the growing evidence base for brief and single-strand treatments over complex or multi-strand interventions. Services characterized by 9-5 working, hourly appointments and face-to-face therapy disenfranchise the majority of people who would benefit from CBT. In this paper we argue that the evidence exists for service protocols that promote equity, accessibility and choice and that CBT services should be organized around multiple levels of entry and service delivery rather than the more usual secondary care referral systems.

The objective of this study was to evaluate the effect of the upstream angle on flow over a trapezoidal broad-crested weir based on numerical simulations using the open-source toolbox OpenFOAM. Eight trapezoidal broad-crested weir configurations with different upstream face angles (θ = 10°, 15°, 22.5°, 30°, 45°, 60°, 75°, 90°) were investigated under free-flow conditions. The volume-of-fluid (VOF) method and two turbulence models (the standard k-ε model and the SST k-w model) were employed in the numerical simulations. The numerical results were compared with the experimental results obtained from published papers. The root mean square error (RMSE) and the mean absolute percent error (MAPE) were used to evaluate the accuracy of the numerical results. The statistical results show that RMSE and MAPE values of the standard k-ε model are 0.35–0.67% and 0.50–1.48%, respectively; the RMSE and MAPE values of the SST k-w model are 0.25–0.66% and 0.55–1.41%, respectively. Additionally, the effects of the upstream face angle on the flow features, including the discharge coefficient and the flow separation zone, were also discussed in the present study.

Cloud computing systems are popular in computing industry for their ease of use and wide range of applications. These systems offer services that can be used over the Internet. Due to their wide popularity and usage, cloud computing systems and their services often face issues resource management related challenges. In this paper, we present v-Mapper, a resource consolidation scheme which implements network resource management concepts through software-defined networking (SDN) control features. The paper makes three major contributions: (1) We propose a virtual machine (VM) placement scheme that can effectively mitigate the VM placement issues for data-intensive applications; (2) We propose a validation scheme that will ensure that a cloud service is entertained only if there are sufficient resources available for its execution and (3) We present a scheduling policy that aims to eliminate network load constraints. We tested our scheme with other techniques in terms of average task processing time, service delay and bandwidth usage. Our results demonstrate that v-Mapper outperforms other techniques and delivers significant improvement in system’s performance.

ABSTRACTT-cell responses to human endogenous retrovirus (HERV) K(HML-2) Gag and Env were mapped in HIV-1-infected subjects using 15mer peptides. Small peptide pools and high concentrations were used to maximize sensitivity. In the 23 subjects studied, only three bona fide HERV-K(HML-2)-specific responses were detected. At these high peptide concentrations, we detected false-positive responses, three of which were mapped to an HIV-1 Gag peptide contaminant. Thus, HERV-K(HML-2) Gag- and Env-specific T-cell responses are infrequently detected by 15mer peptide mapping.

A hierarchic clustering-based enhancement is proposed to solve the luminance compensation of face recognition in the dark field. First, the face image is divided into five levels by a clustering method. Second, the results above are mapped into three hierarchies according to the histogram thresholds. A low, a middle, and a high-intensity block are found. Third, two kinds of linear transforms are performed to the high and the low-intensity blocks. Finally, a center wrap function-based enhancement is carried out. Experiment results show our method can improve both the face recognition accuracy and image quality.

The human immunoglobulin lambda variable locus (IGLV) is mapped at chromosome 22 band q11.1-q11.2. The 30 functional germline v-lambda genes sequenced untill now have been subgrouped into 10 families (V<FONT FACE="Symbol">l</font>1 to V<FONT FACE="Symbol">l</font>10). The number of V<FONT FACE="Symbol">l</font> genes has been estimated at approximately 70. This locus is formed by three gene clusters (VA, VB and VC) that encompass the variable coding genes (V) responsible for the synthesis of lambda-type Ig light chains, and the J<FONT FACE="Symbol">l</font>-C<FONT FACE="Symbol">l</font> cluster with the joining segments and the constant genes. Recently the entire variable lambda gene locus was mapped by contig methodology and its one- megabase DNA totally sequenced. All the known functional V-lambda genes and pseudogenes were located. We screened a human genomic DNA cosmid library and isolated a clone with an insert of 37 kb (cosmid 8.3) encompassing four functional genes (IGLV7S1, IGLV1S1, IGLV1S2 and IGLV5a), a pseudogene (V<FONT FACE="Symbol">l</font>A) and a vestigial sequence (vg1) to study in detail the positions of the restriction sites surrounding the V<FONT FACE="Symbol">l</font> genes. We generated a high resolution restriction map, locating 31 restriction sites in 37 kb of the VB cluster, a region rich in functional V<FONT FACE="Symbol">l</font> genes. This mapping information opens the perspective for further RFLP studies and sequencing

Full textAbstract:
This paper proposes a framework that allows 3D freeform manipulation of a face in live video. Unlike existing approaches, the proposed framework provides natural 3D manipulation of a face without background distortion and interactive face editing by a user’s input, which leads to freeform manipulation without any limitation of range or shape. To achieve these features, a 3D morphable face model is fitted to a face region in a video frame and is deformed by the user’s input. The video frame is then mapped as a texture to the deformed model, and the model is rendered on the video frame. Because of the high computational cost, parallelization and acceleration schemes are also adopted for real-time performance. Performance evaluation and comparison results show that the proposed framework is promising for 3D face editing in live video.

Full textAbstract:
To solve the matching problem of the elements in different data collections, an improved coupled metric learning approach is proposed. First, we improved the supervised locality preserving projection algorithm and added the within-class and between-class information of the improved algorithm to coupled metric learning, so a novel coupled metric learning method is proposed. Furthermore, we extended this algorithm to nonlinear space, and the kernel coupled metric learning method based on supervised locality preserving projection is proposed. In kernel coupled metric learning approach, two elements of different collections are mapped to the unified high dimensional feature space by kernel function, and then generalized metric learning is performed in this space. Experiments based on Yale and CAS-PEAL-R1 face databases demonstrate that the proposed kernel coupled approach performs better in low-resolution and fuzzy face recognition and can reduce the computing time; it is an effective metric method.

Full textAbstract:
The Gabor wavelets are used to extract facial features, and then a doubly nonlinear mapping kernel PCA (DKPCA) is proposed to perform feature transformation and face recognition. The conventional kernel PCA nonlinearly maps an input image into a high-dimensional feature space in order to make the mapped features linearly separable. However, this method does not consider the structural characteristics of the face images, and it is difficult to determine which nonlinear mapping is more effective for face recognition. In this work, a new method of nonlinear mapping, which is performed in the original feature space, is defined. The proposed nonlinear mapping not only considers the statistical properties of the input features, but also adopts an Eigen mask to emphasize those important facial feature points The proposed algorithm is evaluated based on the Yale database, the AR database, the ORL database and the YaleB database.

Introdução: Um dos primeiros problemas a serem tratados nas desordens oclusais, é a correção transversal que pode envolver uma mordida de topo, cruzada uni ou bilateral. Essas atrésias, muitas vezes, podem contribuir nas correções estéticas do sorriso, incluindo assimetrias da face. Objetivo: Visando à correção das assimetrias faciais com a expansão rápida da maxila apoiada em miniparafusos, este trabalho demonstra uma nova técnica por meio da fragilização e expansão unilateral da maxila que facilita o retorno da mandíbula deslocada para o lado ipsilateral da expansão. Relato de caso: Com a utilização de corticoperfurações realizadas na rafe palatina, como já sugerido na literatura, e complementadas também na região de crista infrazigomática no lado oposto à assimetria facial, isso favoreceu o deslocamento mandibular para o lado da expansão, corrigindo assim a estética da face. Considerações Finais: A presente abordagem de fragilização da crista infrazigomática, com o intuito de maior deslocamento de uma hemimaxila para o lado oposto ao desvio facial, pode facilitar algumas correções não cirúrgicas de indivíduos assimétricos.

Sparse representation is a new hot technique in recent years. The two-phase test sample sparse representation method (TPTSSR) achieved an excellent performance in face recognition. In this paper, a kernel two-phase test sample sparse representation method (KTPTSSR) is proposed. Firstly, the input data are mapped into an implicit high-dimensional feature space by a nonlinear mapping function. Secondly, the data are analyzed by means of the TPTSSR method in the feature space. If an appropriate kernel function and the corresponding kernel parameter are selected, a test sample can be accurately represented as the linear combination of the training data with the same label information of the test sample. Therefore, the proposed method could have better recognition performance than TPTSSR. Experiments on the face databases demonstrate the effectiveness of our methods.

3D face recognition is an important topic in the field of pattern recognition and computer graphic. We propose a novel approach for 3D face recognition using local conformal parameterization and iso-geodesic stripes. In our framework, the 3D facial surface is considered as a Riemannian 2-manifold. The surface is mapped into the 2D circle parameter domain using local conformal parameterization. In the parameter domain, the geometric features are extracted from the iso-geodesic stripes. Combining the relative position measure, Chain 2D Weighted Walkthroughs (C2DWW), the 3D face matching results can be obtained. The geometric features from iso-geodesic stripes in parameter domain are robust in terms of head poses, facial expressions, and some occlusions. In the experiments, our method achieves a high recognition accuracy of 3D facial data from the Texas3D and Bosphorus3D face database.

Full textAbstract:
Le concezioni e le prassi di responsabilitŕ sociale d'impresa (CSR, corporate social responsibility) che si sono affermate sino a tempi molto recenti riflettono prevalentemente una logica reattiva, incentrata sulla necessitŕ delle aziende di rilegittimarsi nei confronti dei loro stakeholder corrispondendo alla richiesta di riduzione e prevenzione dei costi sociali legati all'attivitŕ d'impresa (degrado ecologico, disoccupazione conseguente a ristrutturazioni, ecc.). Tuttavia l'attuale periodo, anche per le incertezze e questioni poste dalla crisi economica, rappresenta una fase singolarmente feconda per andare oltre questo approccio adattivo e raccogliere la sfida di una visione piů avanzata della dimensione sociale dell'agire d'impresa come innovazione sostenibile. Tale modello si basa sulla valorizzazione di beni, risorse ed esigenze di significato sociale ed č indirizzato alla creazione di valore integrato - economico, umano-sociale e ambientale - nel lungo termine. La caratteristica centrale di questo profilo d'impresa č la tendenza a operare in maniera socialmente proattiva, sviluppando un'attitudine a cogliere o persino anticipare le direzioni del cambiamento sociale con i suoi bisogni e problemi emergenti e facendo sě che l'integrazione di obiettivi economici e socio-ambientali nei processi strategico-produttivi si traduca in fattore di differenziazione dell'offerta di mercato e in una reale fonte di vantaggio competitivo. Nel presente lavoro si indica la praticabilitŕ di un simile modello riferendosi ai risultati di una recente indagine condotta su un campione di dieci imprese italiane, eterogenee per dimensioni, collocazione geografica, fase del ciclo di vita e settori di attivitŕ, che si estendono da comparti tradizionali (come quelli alimentare, edilizio, sanitario, dell'arredamento e della finanza) a campi di piů recente definizione e a piů elevato tasso di cambiamento tecnologico (quali l'ingegneria informatica, la comunicazione multimediale, il controllo dei processi industriali e il risanamento ambientale). La logica di azione di queste organizzazioni sembra ruotare intorno a una duplice dinamica di "valorizzazione del contesto": da un lato, l'internalizzazione nella strategia d'impresa di richieste e al contempo di risorse sociali orientate a una maggiore attenzione per l'ambiente naturale, per la qualitŕ della vita collettiva nei territori, per i diritti e lo sviluppo delle persone dentro e fuori gli ambienti di lavoro; dall'altro lato, la capacitŕ, a valle dell'attivitŕ di mercato, di produrre valore economico e profitti generando anche valore per la societŕ. Nei casi analizzati č presente la valorizzazione delle risorse ambientali, che si esprime mediante la riprogettazione di prodotti e processi e politiche di efficienza energetica di rifornimento da fonti di energia rinnovabile, raccordandosi con nuove aspettative sociali rispetto alla questione ecologica. Č coltivato il valore umano nel rapporto spesso personalizzato con i clienti e i partner di business ma anche nella vita interna d'impresa, attraverso dinamiche di ascolto e coinvolgimento che creano spazi per la soddisfazione di svariati bisogni e aspirazioni che gli individui riversano nella sfera lavorativa, aldilŕ di quelli retributivi. C'č empowerment del "capitale sociale" dentro e intorno all'organizzazione, ravvisabile specialmente quando le condotte d'impresa fanno leva su risorse relazionali e culturali del territorio e si legano a meccanismi di valorizzazione dello sviluppo locale. Troviamo inoltre il riconoscimento e la produzione di "valore etico" per il modo in cui una serie di principi morali (quali la trasparenza, il mantenimento degli impegni, il rispetto di diritti delle persone) costituiscono criteri ispiratori dell'attivitŕ di business e ne escono rafforzati come ingredienti primari del fare impresa. E c'č, naturalmente, produzione di valore competitivo, una capacitŕ di stare e avere successo nel mercato che si sostiene sull'intreccio di vari elementi. Uno di essi coincide con l'uso della leva economico-finanziaria come risorsa irrinunciabile per l'investimento in innovazione, piuttosto che in un'ottica di contenimento dei costi relativi a fattori di gestione - come la formazione - che possono anche rivelarsi non immediatamente produttivi. Altrettanto cruciali risultano una serie di componenti intangibili che, oltre alla gestione delle risorse umane, sono essenzialmente riconducibili a due aspetti. Il primo č lo sviluppo di know-how, in cui la conoscenza che confluisce nelle soluzioni di business č insieme tecnica e socio-culturale perché derivante dalla combinazione di cognizioni specializzate di settore, acquisite in virtů di una costante apertura alla sperimentazione, e insieme di mappe di riferimento e criteri di valutazione collegati alla cultura aziendale. L'altro fattore immateriale alla base del valore competitivo consiste nell'accentuato posizionamento di marchio, con la capacitŕ di fornire un'offerta di mercato caratterizzata da: a) forte specificitŕ rispetto ai concorrenti (distintivi contenuti tecnici di qualitŕ e professionalitŕ e soprattutto la corrispondenza alle esigenze dei clienti/consumatori e al loro cambiamento); b) bassa replicabilitŕ da parte di altri operatori, dovuta al fatto che le peculiaritŕ dell'offerta sono strettamente legate alla particolare "miscela" degli altri valori appena considerati (valore umano, risorse relazionali, know-how, ecc.). Ed č significativo notare come nelle imprese osservate questi tratti di marcata differenziazione siano stati prevalentemente costruiti attraverso pratiche di attenzione sociale non modellate su forme di CSR convenzionali o facilmente accessibili ad altri (p.es. quelle che si esauriscono nell'adozione di strumenti pur importanti quali il bilancio sociale e il codice etico); ciň che si tratti - per fare qualche esempio tratto dal campione - di offrire servizi sanitari di qualitŕ a tariffe accessibili, di supportare gli ex-dipendenti che avviano un'attivitŕ autonoma inserendoli nel proprio circuito di business o di promuovere politiche di sostenibilitŕ nel territorio offrendo alle aziende affiliate servizi tecnologici ad alta prestazione ambientale per l'edilizia. Le esperienze indagate confermano il ruolo di alcune condizioni dell'innovazione sostenibile d'impresa in vario modo giŕ indicate dalla ricerca piů recente: la precocitŕ e l'orientamento di lungo periodo degli investimenti in strategie di sostenibilitŕ, entrambi favoriti dal ruolo centrale ricoperto da istanze socio-ambientali nelle fasi iniziali dell'attivitŕ d'impresa; l'anticipazione, ovvero la possibilitŕ di collocarsi in una posizione di avanguardia e spesso di "conformitŕ preventiva" nei confronti di successive regolamentazioni pubbliche in grado di incidere seriamente sulle pratiche di settore; la disseminazione di consapevolezza interna, a partire dai livelli decisionali dell'organizzazione, intorno al significato per le strategie d'impresa di obiettivi e condotte operative riconducibili alla sostenibilitŕ; l'incorporamento strutturale degli strumenti e delle soluzioni di azione sostenibile nei core-processes organizzativi, dalla ricerca e sviluppo di prodotti/ servizi all'approvvigionamento, dall'infrastruttura produttiva al marketing. Inoltre, l'articolo individua e discute tre meccanismi che sembrano determinanti nei percorsi di innovazione sostenibile osservati e che presentano, per certi versi, alcuni aspetti di paradosso. Il primo č dato dalla coesistenza di una forte tradizione d'impresa, spesso orientata sin dall'inizio verso opzioni di significato sociale dai valori e dall'esperienza dell'imprenditore-fondatore, e di apertura alla novitŕ. Tale equilibrio č favorito da processi culturali di condivisione e di sviluppo interni della visione di business, da meccanismi di leadership dispersa, nonché da uno stile di apprendimento "incrementale" mediante cui le nuove esigenze e opportunitŕ proposte dalla concreta gestione d'impresa conducono all'adozione di valori e competenze integrabili con quelli tradizionali o addirittura in grado di potenziarli. In secondo luogo, si riscontra la tendenza a espandersi nel contesto, tipicamente tramite strategie di attraversamento di confini tra settori (p.es., alimentando sinergie pubblico-private) e forme di collaborazione "laterale" con gli interlocutori dell'ambiente di business e sociale; e al contempo la tendenza a includere il contesto, ricavandone stimoli e sollecitazioni, ma anche risorse e contributi, per la propria attivitŕ (p.es., nella co-progettazione dei servizi/prodotti). La terza dinamica, infine, tocca piů direttamente la gestione delle risorse umane. Le "persone dell'organizzazione" rappresentano non soltanto uno dei target destinatari delle azioni di sostenibilitŕ (nelle pratiche di selezione, formazione e sviluppo, welfare aziendale, ecc.) ma anche, piů profondamente, il veicolo fondamentale della realizzazione e del successo di tali azioni. Si tratta, cioč, di realtŕ organizzative in cui la valorizzazione delle persone muove dagli impatti sulle risorse umane, in sé cruciali in una prospettiva di sostenibilitŕ, agli impatti delle risorse umane attraverso il loro ruolo diretto e attivo nella gestione dei processi di business, nella costruzione di partnership con gli stakeholder e nei meccanismi di disseminazione interna di una cultura socialmente orientata. In tal senso, si distingue un rapporto circolare di rinforzo reciproco tra la "cittadinanza nell'impresa" e la "cittadinanza dell'impresa"; vale a dire, tra i processi interni di partecipazione/identificazione del personale nei riguardi delle prioritŕ dell'organizzazione e la capacitŕ di quest'ultima di generare valore molteplice e "condiviso" nel contesto (con i clienti, il tessuto imprenditoriale, le comunitŕ, gli interlocutori pubblici, ecc.). In conclusione, le imprese osservate appaiono innovative primariamente perché in grado di praticare la sostenibilitŕ in termini non solo di responsabilitŕ ma anche di opportunitŕ per la competitivitŕ organizzativa. Questa analisi suggerisce quindi uno sguardo piů ampio sulle implicazioni strategiche della CSR e invita a riflettere su come le questioni e i bisogni di rilievo sociale, a partire da quelli emergenti o acuiti dalla crisi economica (nel campo della salute, dei servizi alle famiglie, della salvaguardia ambientale, ecc.), possano e forse debbano oggi sempre piů situarsi al centro - e non alla periferia - del business e della prestazione di mercato delle imprese.

Functional biogeography may bridge a gap between field-based biodiversity information and satellite-based Earth system studies, thereby supporting conservation plans to protect more species and their contributions to ecosystem functioning. We used airborne laser-guided imaging spectroscopy with environmental modeling to derive large-scale, multivariate forest canopy functional trait maps of the Peruvian Andes-to-Amazon biodiversity hotspot. Seven mapped canopy traits revealed functional variation in a geospatial pattern explained by geology, topography, hydrology, and climate. Clustering of canopy traits yielded a map of forest beta functional diversity for land-use analysis. Up to 53% of each mapped, functionally distinct forest presents an opportunity for new conservation action. Mapping functional diversity advances our understanding of the biosphere to conserve more biodiversity in the face of land use and climate change.

Abundance trends are the basis for many classifications of threat and recovery status, but they can be a challenge to interpret because of observation error, stochastic variation in abundance (process noise) and temporal autocorrelation in that process noise. To measure the frequency of incorrectly detecting a decline (false-positive or false alarm) and failing to detect a true decline (false-negative), we simulated stable and declining abundance time series across several magnitudes of observation error and autocorrelated process noise. We then empirically estimated the magnitude of observation error and autocorrelated process noise across a broad range of taxa and mapped these estimates onto the simulated parameter space. Based on the taxa we examined, at low classification thresholds (30% decline in abundance) and short observation windows (10 years), false alarms would be expected to occur, on average, about 40% of the time assuming density-independent dynamics, whereas false-negatives would be expected to occur about 60% of the time. However, false alarms and failures to detect true declines were reduced at higher classification thresholds (50% or 80% declines), longer observation windows (20, 40, 60 years), and assuming density-dependent dynamics. The lowest false-positive and false-negative rates are likely to occur for large-bodied, long-lived animal species.
