AAL domain ontology for event-based human activity recognition (2014)

The design of an Ambient Assisted Living (AAL) aims to create better living conditions for the elderly, especially those who choose to live in their own houses, as long as possible. To this objective, AAL systems must mainly monitor the health status of the elderly through the analysis of data gathered via technologies based on sensor devices. Sensors networks produce collections of data of fine-grained nature, regarding general information such as device name, data type, data value, timestamp, but also specific one. The data analysis, due to its granularity and heterogeneity, makes very difficult to infer a clear overall view of the status of the elderly, it demands automatic tools for selecting meaningful data and mapping them in a common conceptual schema. In the last decade, ontologies became widely used tool to describe application domains and to enrich data with its meaning. In this paper, we propose an ontology-based methodology to perform semantic queries on a data repository, where records originated from networks of heterogeneous sources are stored. A semantic query is a pattern matching process that supports the recognition of specific temporal sequences of events that can be extracted from fine-grained data. In our framework a domain ontology are exploited at different levels of abstraction and the reasoning techniques are used to pre-process data for the final temporal analysis. The proposed approach is a deliverable of the ongoing AALISABETH project funded by Region Marche Government; while the software component is integrated into the AALISABETH framework.
Obstacle avoidance by combining background subtraction, optical flow and proximity estimation (2014)

For Micro Aerial Vehicles (MAVs), robust obstacle avoidance during flight is a challenging problem because only light weight sensors as monocular cameras can be mounted as payload. With monocular cameras depth perception cannot be estimated from a single view, which means that information has to be estimated by combining images from multiple viewpoints. Here we present a method which focuses only on regions classified as foreground and follow features in the foreground to estimate threat of potential objects being an obstacle in the flight path by depth segmentation and scale estimation. We evaluate results from our approach in an outdoor environment with a small quadrotor drone and analyze the effect of the different stages in the image processing pipeline. We are able to determine evident obstacles in front of the drone with high confidence. Robust obstacleavoidance algorithms as presented in this article will allow Micro Aerial Vehicles to navigate semi-autonomously in outdoor scenarios.
Uniform purging of resins in contact bed purge vessels (1999)

Abstract Resin storage vessels such as bins, silos, and tanks often double as purge vessels, in which products are purged of volatiles or polymerization reactions are controlled. Processing is achieved by gas flowing among resin particles or pellets. Problems associated with these purge vessels include typical bin flow problems such as flow stoppages due to arching or ratholing, erratic discharge, particle segregation, and flooding or flushing. In addition, purging may be non‐uniform or incomplete, and cross contamination between grades may occur. These problems are often the result of either a funnel flow pattern, where some of the material in the vessel moves while the rest remains stationary, or a non‐uniform velocity profile, where some parts of the vessel flow much faster than others. Also, the location and the manner in which gas is injected into the vessel contents affect the uniformity of exposure of polymer particles to the gas. This paper describes methods of designing purge vessels to eliminate stagnant regions. Also, velocity gradients of solids in mass flow vessels (where all of the material is in motion whenever any is withdrawn) are discussed. Considerations of the gas introduction schemes that do not disturb the resin flow patter are also described.

Increased risk of zinc deficiency in wheat on soils limed to correct soil acidity (2005)

Addition of lime to ameliorate soil acidity has been observed to induce zinc (Zn) deficiency for wheat in sandy soils of south-western Australia, reducing grain yields. The implications of widespread use of lime to treat acid soils for the residual value of Zn in these soils are not known. In a glasshouse experiment, using a Zn-deficient sand from south-western Australia, 3 levels of finely powdered calcium carbonate were added and incubated in moist soil for 6 weeks at 22°C to produce three different pH values (1 : 5 soil : 0.01 m CaCl2): 4.9 (original soil not treated with calcium carbonate), 5.8, and 7.4. Five amounts of Zn, as solutions of Zn sulfate, were then incubated in moist soil for 0, 30, 60, 120, and 180 days before sowing spring wheat (Triticum aestivum L.). The residual value of the applied Zn was determined using yield of dried shoots, Zn content in dried shoots, and soil test Zn (DTPA extraction). This was done by calculating the effectiveness of the incubated Zn for all 3 soils relative to the effectiveness of Zn applied just before sowing wheat (0 day incubation, freshly applied Zn) for the soil not treated with calcium carbonate. As measured using yield of dried shoots, Zn content of dried shoots, or soil test Zn, the residual value of the incubated Zn decreased with increasing soil pH and with increasing period of incubation of Zn with moist soil before sowing wheat. The critical Zn concentration, associated with 90% of the total yield of dried wheat shoots, was (mg Zn/kg) 13 in the youngest mature growth (apex and youngest emerged leaf), and 20 for rest of dried shoots. These values were similar to current critical values for unlimed soils. The relationship between yield of dried shoots and DTPA soil test Zn was similar for unlimed and limed soils, so similar critical soil test Zn was applicable on the sandy soil regardless of soil pH. Critical DTPA soil test Zn, the soil test Zn that was related to 90% of the maximum yield of dried shoots, was 0.14 mg Zn/mg soil. To combat the increased risk of Zn deficiency on soils limed to ameliorate soil acidity, fertiliser Zn needs to be re-applied to the soil when soil and plant tests indicate a high likelihood of deficiency.
Early prediction of acute kidney injury using machine learning algorithms (2018)

The application of machine learning algorithms in the medical sector is gaining increased attention in the last few decades. Thus, the main aim of this manuscript is to compare the performance of well-known machine learning (ML) algorithms to a problem in the domain of medical diagnosis and analyze their efficiency in predicting the results. The problem that has been considered in this study is the detection of acute kidney injury (AKI). The ML algorithms are Support Vector Machine (SVM), Neural Network (NN), Deep learning, Decision trees and Naiive Bayes. This research proposed i) an AKI Model: AKI (indicator of renal function) represents a significant risk factor for mortality for patients in ICU, ii) to use analytics to improve clinical decision support by taking advantage of the massive amounts of data and provide right intervention to the right patient at the right time, iii) to use analytics for better care coordination.
Clock generation for a 32nm server processor with scalable cores (2011)

This paper presents the implementation of a clock system targeting low-power low-skew high-data throughput and low latency for a next-generation Xeon <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> server processor with scalable cores in a 32nm 9-metal digital CMOS process.
Satellite CNS for maritime transportation augmentation system (MTAS) (2009)

The development of the MTAS was to identify the possible applications for enhancement of Digital Selective Call (DCS) MF/HF/VHF Radio; Satellite Communications, Navigation and Surveillance (CNS); GPS and GLONASS; and safety systems including security and control of vessels, logistic and freight at sea, on inland waters and the security of crew and passengers on board ships, cruisers, boats and hovercrafts. These enhancements include many applications for the better management and operation of vessels and they are needed more than ever because of world merchant fleet expansion. Just the top 20 world ships registers have about 40,000 units under their national flags. Above all, the biggest problem today is that merchant ships and their crews are targets of the types of crime traditionally associated with the maritime industries, such as piracy, robbery and recently, a target for terrorist attacks. Thus, IMO and flag states will have a vital role in developing International Ship and Port Security (ISPS). The best way to implement ISPS is to design an Approaching and Port Control System (APCS) by special code augmentation satellite CNS including tracking and monitoring of all vehicle circulation in and out of the port area. The establishment of MTAS as a part of Global Satellite Augmentation Systems (GSAS) or GNSS-1, such as the US WAAS, European EGNOS, Japanese MSAS, Chinese SNAS, Indian GAGAN and future GSAS including African Satellite Augmentation System (ASAS) will meet all these requirements and will complement the services already provided by DGPS or Local VHF Augmentation System (LVAS) and MF radio beacons.
PRIMARY FAMILIAL XANTHOMATOSIS WITH INVOLVEMENT AND CALCIFICATION OF THE ADRENALS (1961)

THIS PAPER deals with the description of clinical, pathologic, histochemical and biochemical findings in two cases of generalized xanthomatosis with calcification of the adrenals. The infants were siblings of a previously described patient,1 and and the findings warrant the conclusion that the disease process was identical in all three. The study of these cases and review of pertinent literature indicates that primary xanthomatosis (idiopathic lipidosis with deposition of cholesterol and triglycerides) is a metabolic disease entity that is independent of the granulomatous process called histiocytosis X, or eosinophilic xanthomatous granuloma. It will be shown in the discussion that primary xanthomatosis may occur in various forms, and that the form described in this paper is a rare but distinct clinical and pathologic type. This type differs in the distribution of lesions from other types of primary xanthomatosis, such as the type of cerebral xanthomatosis described by van Bogaert, Scherer and Epstein, and the type associated with involvement of bones that sometimes produces the Hand-Schüller-Christian syndrome. For reasons that wiil be clarified in the discussion, the term "Hand-Schüller. Christian disease" is not adopted in this paper. The term "Hand-Schüller-Christian syndrome" indicates a well-known syndrome with exophthalmos, diabetes insipidus and peculiar bone changes. The term "primary xanthomatosis" describes a primary (i.e., idiopathic) storage process in which triglycerides and cholesterol are deposited in various tissues. CASE REPORTS Case 1 Family History: The two infants described in this article and the infant previously described1 were female siblings born to closely related parents. The father and mother, both Persian Jews, were cousins.
Changes in the Physical State of Sucrose during Dark Chocolate Processing (2001)

Dark chocolate tablets were manufactured using 100% crystalline sucrose, 50% crystalline and 50% amorphous sucrose, and 100% amorphous sucrose. The physical state of sucrose was determined by differential scanning calorimetry (DSC) and X-ray diffraction. DSC scans of dark chocolate samples containing amorphous sucrose were characterized by a glass transition at 63 degrees C, a sucrose crystallization peak at 105 degrees C, and a melting endotherm at 188 degrees C. Independent of the amount of amorphous or crystalline sucrose used for the preparation of dark chocolate, all final chocolate products provided a single melting endotherm at 188 degrees C and a crystalline X-ray diffraction pattern. These results indicated that sucrose crystallized during production of dark chocolate and that no amorphous sucrose was present in the final chocolate products.

What qualitative research can be (1999)

Corporate America deserves more than it has been getting for its qualitative research dollar. Qualitative research with consumers can be more systematic, more psychological, and more innovative. The everyday business of qualitative research has the potential of becoming a true profession. The added value psychologists can bring to this profession is explored with reference to an approach called dimensional qualitative research. It is argued that quality in qualitative research with consumers can best be achieved through the systematic application of a psychological model that allows for innovation. © 1999 John Wiley & Sons, Inc.
Multimode interference optical splitter based on photodefinable benzocyclobutene (BCB 4024-40) polymer (2007)

1×2 and 1×3 planar optical splitters based on Benzocyclobutene (BCB 4024-40) polymeric material are demonstrated for the first time. The devices are designed based on symmetric interference and fabricated on BK7 glass substrates with a thin layer of SiO2 as cover. A cost-effective chemical etching technique is used in the fabrication process to take advantage of the photosensitivity of the polymer. The waveguide loss was measured using the cutback method to be 3.5 dB/cm. The splitting uniformity is better than 0.02 and 1.5 dB at 1550-nm optical wavelength for the 1×2 and 1×3 splitters, respectively.
Low Complexity 2D Adaptive Channel Estimation for OFDM Based Two-Way Relay Systems (2013)

This paper introduces a low complexity adaptive channel estimation technique for OFDM based two-way relay systems. The adaptive filter used is known as Group Fast Array Multichannel 2D-Recursive Least Square (GFAM 2DRLS) filter. It has a computational complexity comparable to that of 2D-Normalized Least Mean Square (2D-NLMS) algorithm while maintaining the same convergence rate as the classic 2D Recursive Least Square (2D-RLS) algorithm. It considers the correlation of the channel frequency response in both time and frequency, while estimating the channel. In order to reduce the number of training data for time varying channel, the channel estimation is carried out based on the Decision Directed (DD) principle. It is assumed that the relay is capable of performing complex signal processing tasks. Hence the channel estimation is performed at the relay. Since the Channel State Information (CSI) is available at the relay, it could perform Multiple Input Multiple Output (MIMO) precoding of the transmitted data. Hence CSI is not required at the transmitting nodes. The convergence rate of GFAM 2D-RLS is compared with the existing 2D-NLMS algorithm and the computational complexity at each iteration is tabulated. Simulations are performed using MATLAB.
Mirror-Image Kinematics (1960)

A matrix [M] is derived for a system of plane first-surface mirrors which transforms a point or the direction cosines of a ray in the image space to the object space. If the general displacement of the mirror system is represented by the screw matrix [S], then the new position of a point image is given by the transformation [S][M][S]−1. This method facilitates designing the mirror supporting structure for minimum image shift due to structural deflections.

The role of polycarbonate molecular weight in the poly(<scp>L</scp>‐lactide) blends compatibilized with poly(butylene succinate‐<i>co</i>‐<scp>L</scp>‐lactate) (2012)

Abstract Poly(butylene succinate‐ co ‐ L ‐lactate) (PBSL)–compatibilized poly( L ‐lactide) (PLLA) polymer blends with two commercial grades of polycarbonate (PC) were investigated. The capillary tests showed that the steady shear viscosity of high molecular weight PC (PC‐L) was 10 times higher than that of low molecular weight PC (PC‐AD) throughout the shear rate range under investigation. Morphologic examination revealed that the shape of the dispersed PC‐L phase in the as‐extruded blends was largely spherical, but the PC‐AD phase was more like a rod and elongated further during injection molding. Notched Izod impact strength (IS) of the unmodified PLLA/PC‐L blend was higher than that of PC‐AD blend. The IS of modified ternary blends increased with PBSL content because of enhanced phase interaction indicated from thermal and morphologic analysis. The PBSL modification also enhanced IS more significantly in PLLA/PC‐L than in PLLA/PC‐AD blends. On the contrary, the heat deflection temperature (HDT) of PLLA/PC‐L binary system was much lower than that of PLLA/PC‐AD. HDT of PBSL‐modified PLLA/PC‐AD blends dropped with increasing PBSL content, which is a ductile polymer. Thermal and dynamic mechanical analysis of the ternary blends showed that individual components were immiscible with distinct T g s for PC and PLLA and distinct T m s for PBSL and PLLA. POLYM. ENG.

Impact of filtering chaotic signals on secure wireless communication systems based Chua's circuit (2013)

One of the challenging issues involved in the development of future chaos-based secure communication (CBSC) for wireless applications is the synchronization between transmit and receive nodes. In this paper, effects of filtering chaotic signals of CBSC due to finite bandwidth of realistic channel environment and/or detection requirements on the synchronization are investigated. The double scroll chaotic attractor using Chua's circuit is employed at the transmit and receive nodes. Over wide range of filter cut-off frequency (η), simulation results show that as η decreased, below the bandwidth of chaotic signal (W), the synchronization error is increased due to high distortion in the normal geometrical configuration (state-space) of the attractor. Consequently, the system performance will be degraded significantly with high possibility of communication link failure. Thus, careful design should be made to eliminate the impact of filtering and achieve the essential synchronization towards the wide adoption of CBSC in next-generation systems.
