Airborne laser communication terminal for intelligence, surveillance and reconnaissance

Sensors which collect information for intelligence, surveillance and reconnaissance generate a substantial amount of data. High data rates are required to transmit the information in reasonable time intervals. This paper describes the objectives and progress on the development of laser communication terminals for aircraft, transmitting high speed data over distances greater than 100 kilometers. The terminals are being designed and built under the Air Force Research Laboratory’s EO Sensor Technology & Evaluation Research (ESTER) program. The free space laser communication system consists of three terminals developed around commercial fiber-optic standards. They are designed to be an open system, full duplex, protocol neutral, and operate at 2.5 gigabit per second, capable of expanding to 10 gigabit per second. The terminal’s data rate can be reduced if atmospheric effects cause a significant increase in bit error rate. The free space optics are mounted in a pointing & tracking gimbal which interfaces with an avionics unit that measures aircraft GPS information. Fine pointing and tracking is maintained by using a beacon signal which switches from wide to narrow divergence when signal lock is achieved. The terminals are designed to operate in air-to-ground and air-to-air scenarios. Subsystem laboratory tests are being completed and the terminals are being prototyped. The first set of tests will be conducted between ground sites and the first flight demonstration will involve interfacing with the multi-purpose common data link (MP-CDL) on an aircraft. We provide a description of our terminal design, show our estimated operational performance, describe the results of laboratory testing, and outline the future program activities.
A comparison of "on-thigh" vibrotactile, combined visual-vibrotactile, and visual-only alerting systems for the cockpit under visually demanding conditions

In the cockpit, performance is prone to break down. Conveying crucial information through the tactile modality, which requires little to no additional effort, has been previously examined as means to improve performance and safety. Previously, we demonstrated the ability of the on-thigh vibrotactile alerting display to convey directional cues in the vertical plane. We hypothesized that tactile directional alerting cues would be beneficial in a visually loaded multi-tasking environment. In the current study, two tasks were introduced simultaneously: a directional task where participants respond to directional cues (visual, tactile, or combination of both), and a visual-memory recall task where participants identify, count and recall objects embedded in flight movies. Response time, accuracy and subjective workload were evaluated. Performance in the memory recall task and subjective workload were in favor of the combined tactile & visual configuration. No performance difference was found between visual and tactile & visual in the directional task. We conclude that the tactile & visual configuration may allow operators to choose a strategy in which perceptual and cognitive resources are better utilized.
Enhancement mode AlGaN/GaN HFET with selectively grown pn junction gate

A report is presented into the fabrication and characterisation of an enhancement mode AlGaN/GaN heterojunction field-effect transistor (HFET) with selectivity grown pn junction gate. At zero gate bias the device channel is depleted due to the high built-in potential of the gate-channel junction. The selective area growth approach enables both depletion and enhancement mode HFETs to be fabricated on the same wafer thus opening up the possibility of designing high speed, low consumption GaN-based logical integrated circuits.
Automotive mm-wave radar: status and trends in system design and technology

Automotive millimetre-wave radar sensors are moving rapidly from a research and development status in the pre-production phase. The rapid progress in RF-technology, the explosion of processing speed, and decreasing prices of mm-wave components make radar more and more interesting as a consumer product. For monitoring the car's motion and surroundings (especially in the direction of motion) radar systems have been investigated and applied since the early 1970s by all major car companies, many institutes and laboratories. Automotive radar facilitates various functions that increase the driver's safety and convenience. Exact measurement of distance and relative velocity of objects in front, beside, or behind the car allow the realisation of systems which improve the driver's ability to perceive objects during bad optical visibility or objects hidden in the blind spot during changing lanes or parking manoeuvres. Especially, the forward looking radar type is extensively tested by nearly all major car companies world-wide either for obstacle warning (OWR) or to allow autonomous intelligent cruise control (AICC) functions. This paper reviews the development status in millimetre-wave forward looking radar sensors for automotive applications in Europe, the US, and Japan and reports on trends in system design and technology.
Approaches to Managing Future Training

Abstract : This report explores issues related to managing adaptable training in the future, when Future Combat Systems (FCS), embedded training (ET) capabilities, and a full range of personnel management tools are the norm for daily operations. The report first discusses the issues associated with management of future training and related current and emerging Army initiatives, FCS documentation, and previous research findings. The five principal issues concern the vision and expectation for future training; the tools and information that would be needed; how the tools and information could be provided using automated channels; what level of automation users will accept; and the nature of near-term solutions. The concept for a future training management system, is described through use cases that detail the use of specific tools and information. Based on analysis of the use cases, technology needs are described in five areas: massive database systems, bi-directional reach (both accessing and sending needed information), sophisticated self-learning search engines, performance support systems and computer-generated simulations powered by artificial intelligence, and super-broad bandwidth. We then present a set of detailed recommendations, including priorities, interim solutions for near-term development, and directions for further research and development in both training and technology realms.
Addictiveness: an independent dimension in the psychotic
syndrome. Presentation of the Addictiveness in the Psychotic
Syndrome Assessment Scale (APSAS)

Models of dual pathology habitually consider substance-use disorders (SUD) and the rest of mental disorders as two pathological conditions coincident in a same person. This study adopts a different point of view and accept adictivity as the nineth clinical dimension in the psychotic disorders to be added to hallucinations, delusion, disorganised speech, abnormal psychomotor behaviour, negative symptoms, cognitive deficit, depression, and mania. In the last term, all of them seems to derive from a common fronto-subcortical disfunction with dopaminergic, glutamatergic and gabaergic implication. The Scale for the Evaluation of Adictivity in the Psychotic Syndrome (SEAPS) is presented. It wants to be an integrated and easy to use tool for evaluating adictivity in the psychotic disorders. It is based in data collected with respect of first use, length of use, last use, frequency of use and addiction intensity regarding twelve types of substances or addictive behaviours. Results of the application of SEAPS on a sample of 105 psychotic subjects suggest good psychometric characteristics as well as the independency of adictivity respect with other clinical dimensions.

Zeroth-order resonant circular patch antenna based on periodic structures

The circular patch antenna loaded with a periodic structure implementing a composite right/left-handed transmission line (TL) is introduced. The corresponding circuit model of the radial TL is derived to analyse this circular antenna. Since the unit cells of this TL can support arbitrary phase shift, the antenna can form negative modes, positive modes and zeroth-order resonant (ZOR) modes. For a ZOR antenna, the resonant frequency is independent of its physical size. The resonant frequency, input impedance and radiation characteristics of the ZOR circular antenna are analysed in terms of the physical parameters of the unit cells. Two ZOR circular antennas are designed showing monopolar radiation patterns. One is electrically extremely large, yielding a high directivity, and the other one is electrically small.
Applications for the MATILDA robotic platform

Most robotic platforms have, up to this point, been designed with emphasis placed on improving mobility technologies. Minimal emphasis has been placed on payloads and mission execution. Using a top-down approach, Mesa Associates, Inc. identified specific UGV mission applications and structured its MATILDA platform using these applications for vehicle mobility and motion control requirements. Specific applications identified for the MATILDA platform include: Target surveillance, explosive device neutralization, material pickup and transport, weapon transport and firing, and law enforcement. Current performance results, lessons-learned, technical hurdles, and future applications are examined.
Microwave sintering response of different grade stainless steels and its influence on metallurgical properties

Ultra-rapid microwave sintering of powder metals will provide fine microstructural features that improve mechanical properties. In present study, three grades of stainless steel powder compacts (316L, 430L, 410) were produced using a uniaxial compaction unit. These compacts were sintered by microwave hybrid heating method at 1300°C (super-solidus region). The densification response, microstructural attributes, and mechanical properties were compared at 30, 45 and 60 min holding times. The compositional analysis was performed with the help of optical emission spectroscopy (OES) and scanning electron microscopy equipped with energy dispersed spectroscopy(SEM-EDS). The results obtained from both spectroscopies are compared for the sintered samples. The correlation of mechanical properties is analysed with evolved microstructural attributes (pore volume, pore shape and pore distribution). The excellent strength of 457 ± 16 MPa, 466 ± 6 MPa and 476 ± 26 MPa with 23 ± 1.3%, 14 ± 1.5% and 11 ± 1% of ductility is observed for sintered AISI 316L, 430L and 410, respectively.
PCR analysis of the effect of photodynamic therapy on breast tumors

Photodynamic therapy (PDT) is a promising therapeutic modality for treating cancer, including breast tumors. The oxidative damage caused by PDT culminates in cell death, induction of immune response, and the resulting destruction of the tumor. This study aimed to evaluate the gene expression profiling of genes BCL-2, BAX, and HER-2 and their proteins after PDT, associating it with the necrosis caused by this therapy under different fluences. Twenty-eight female rats received a single dose of 7,12-dimethylbenz (a) anthracene (DMBA - 80mg/kg), by gavage, for breast tumor induction. After the tumors grew, the animals were divided into four groups: G1 - control group – untreated breast tumor – and G2, G3, and G4 groups treated with PDT using Photogem@ as photosensitizer and interstitial irradiation, with fluences of 50J/cm, 100J/cm, and 150J/cm, respectively. Samples of tumors were harvested for histological examination by RT-qPCR. The RT-qPCR showed that the gene expression profiling of BCL-2, BAX, and HER-2 was not altered after PDT. Hemorrhagic necrosis and qualitatively greater vascular and cellular damage were observed and correlated positively with the fluence. PDT does not seem to induce the modulation of genes related to apoptosis. The results indicate that the type of cell death stimulated by PDT in breast tumor is necrosis.
Predicting the Cumulative Fluid Intake in Cardiac Intensive Care Patients

⎯ Fluid balance can be considered a valuable biomarker of critical illness. Administering the right dosage over time of fluids, thereby avoiding fluid overload, remains a challenge in intensive care. As a first step towards a fluid management decision support system, this work compared four models for predicting the course of the cumulative fluid intake in 30 cardiac intensive care patients. Analyses of the root mean squared error (RMSE) showed the lowest prediction error for an extrapolation model using a piecewise regression-approach. Keywords⎯ Cumulative fluid intake, prediction, fluid overload, fluid balance, intensive care
A new fuzzy-fractal approach for surface quality control in intelligent manufacturing of materials

We describe a general method to automate quality control in the manufacturing of materials using a fuzzy-fractal approach. We also show how to implement this method in an intelligent system to achieve automated quality control in practice. Engineers deal with surfaces and surface properties in a wide variety of contexts. In manufacturing, the goal is to produce a surface with specific physical or chemical properties. The concept of the fractal dimension can be used to classify a complex geometrical object. In this case, we use the fractal dimension to characterize surface roughness of materials for manufacturing applications. On the other hand, we use fuzzy logic techniques to simulate the expert evaluation/decision process to obtain the quality of manufactured materials. Quality evaluation is simulated in an intelligent system using as input the information about material roughness and porosity (fractal dimension), and then by applying a set of fuzzy rules to decide, on the degree of quality of the production.
Novel Low-Bend Large Effective Area Fiber for Fiber-to-the-Home Application

Abstract In this article, with sophisticated modification on modal field distribution and introducing a new design procedure, a single-mode fiber with ultra-low bending loss and large effective area (Aeff) that is appropriate for a fiber-to-the-home operation is presented. The bending loss optimization procedure is based on the genetic algorithm. The most remarkable feature of this methodology is designing a bend-insensitive fiber without reduction of core radius and mode field diameter. The designed structure exhibits very small bending loss and large Aeff simultaneously. Simulation results show bending loss of 2.7 × 10−3 dB at 1.55 μm for a single turn of 5-mm radius. The calculated mode field diameter and Aeff for the designed structure are 9.00 μm and 63.62 μm2, respectively.
Entrapment of Phenylalanine Ammonia-Lyase in Nanofibrous Polylactic Acid Matrices by Emulsion Electrospinning

Immobilization of the recombinant, plant-derived Petroselinum crispum phenylalanine ammonia lyase (PcPAL) in electrospun matrices have the potential to create promising, easy-to-use biocatalysts. Polylactic acid (PLA) a biologically inert, commercial biopolymer, was chosen as the material of the carrier system. PLA could be electrospun properly only from water-immiscible organic solvents, which limits its application as a carrier of sensitive biological objects. The emulsion electrospinning is a proper solution to overcome this issue using non-ionic emulsifiers with different hydrophilic-lipophilic balance (HLB) values. The stabilized emulsion could protect the sensitive PcPAL dissolved in the aqueous buffer phase and improve fiber formation, plus help to keep the biocatalytic activity of enzymes. In this study, the first approach is described to produce PLA nanofibers containing PcPAL enzymes by emulsion electrospinning and to use the resulted biocatalyst in the ammonia elimination reaction from l-phenylalanine.
Lead pipe and lead–tin solder scale formation and structure: A conceptual model

Lead–tin solder and lead service lines (LSLs) are important sources of lead, and after LSLs are removed, lead–tin solder will remain a major source of lead. A better understanding of the factors that control lead release from solder joints can help water utilities reduce lead. This paper reviews the reactions that take place at galvanic connections involving both lead–tin solder and lead pipe in contact with copper. A conceptual model based on these reactions was developed and is presented here to explain how such scale structure forms. The likely reactions that affect lead release for each of three cases, (1) no galvanic action, (2) lead anode and copper–brass cathode, and (3) lead cathode and copper–brass anode, are presented. The model also considers uniform corrosion that takes place on LSLs. This model should be useful when evaluating the impact of water quality changes on lead release from galvanic connections and LSLs.
To whom should I be kind? A randomized trial about kindness for strong and weak social ties on mental wellbeing and its specific mechanisms of change

The current study examines the role of social ties in performing kind acts to enhance university students’ wellbeing. Due to facing multifaceted challenges, university students form a group that is particularly vulnerable in terms of their mental health. Interventions harnessing prosocial behaviour have the potential to increase students’ wellbeing, strengthen personal competencies, and broaden social networks. The first aim of the trial (N = 222) was to explore whether a 4-week acts-of-kindness intervention targeting either (1) strong social ties, (2) weak social ties or (3) unspecified receivers (treatment-as-usual) differ in their impact on students’ mental wellbeing, positive relations, depressive symptoms, anxiety, and perceived stress. The second aim was to examine whether kindness for strong versus weak social ties have different underlying working mechanisms (i.e., positive emotions versus self-esteem) and who benefits most from these instructions (i.e., those with high or low levels of self-esteem and positive relations). Results demonstrated that the most significant improvements in mental wellbeing were found in the kindness for strong social ties condition compared to the other conditions. No mediation effects of positive emotions and self-esteem were found. Moderation analyses revealed that participants who performed kind acts for weak social ties reported significantly less positive effects on mental wellbeing, but only when their levels of self-esteem at baseline were medium or high. Independent of group allocation, participants’ mental wellbeing increased throughout the intervention, but so did the experience of depressive symptoms, anxiety, and perceived stress. More research is needed to examine the timing of kindness interventions and investigate how they can improve mental wellbeing and psychological distress in acute phases of academic stress in university students.
Development and Verification of Validity of Social Adaptation Scale for Adolescents

: The purpose of this study is to develop a social adaptation scale for adolescents. To achieve this purpose, the first preliminary scale was derived after selecting items based on prior research and verifying the content validity of the derived 3 factors (school adaptation, family adaptation, friends adaptation) and items. ” In order to develop the scale, a questionnaire survey was conducted on 217 teenagers living in Daegu City, South Korea. With collected data, a confirmatory factor analysis was conducted to examine the construct validity of the preliminary scale. Through this scale development process, this study finally developed a final scale consisting of 9 items in three components that constitute adolescent social adaptation. The social adaptation scale verified and developed in this study can help adolescents to lead a more vibrant life by confirming the degree of adaptation to their families, friends, and school. Furthermore, developed scale help to verify the effectiveness of social services provided to adolescents as an important tool. The social adaptation scale developed in this study will reliably measure and evaluate the performance of social adaptation targeting adolescents, and the relationship with schools, families, and classmates will be further improved. In addition, it is expected that systematic feedback information can be provided for the organization and operation of career education courses.
Synergy between design and process: A key factor in the evolving microelectronic landscape

In scaling down the dimensions of the transistors in integrated circuits, major issues need to be solved. As we approach the resolution limit of the lithographic tool, extensive modifications of the patterns need to be performed on the mask in order to match the expected features on the circuit. More and more trade-offs need to be addressed in designing complex circuits like power consumption, variability, error rate, etc.: a better interplay between the technology constraints and the design complexity has to be developed. Moving to non conventional CMOS (e.g. FinFET) induces specific issues to be dealt with through the design style. On the far end of this spectrum emerging research devices and architectures, as they are called in the ITRS roadmap, may need ‘out-of-the box’ thinking in the way complex systems and applications will be integrated.
