Autonomous Geo location of RF Emitters Using Small , Unmanned Platforms

636 utonomous geo location of RF emitters using small, unmanned systems is a game-changing technology for military, government, and commercial missions. This technique employs a novel application of a common RF direction-finding technique called pseudo-Doppler. Emergent autonomous control concepts are used to control the sensor platform and optimize flight trajectories for efficient and rapid geo location of the target. The basic components of this concept, from sensor development to unmanned system autonomous behaviors, were tested in simulation and subsequently demonstrated in flight during the Tactical Network Topology experiment.

Alkynylation of Thiols with Ethynylbenziodoxolone (EBX) Reagents: α- or β- π-Addition?

The alkynylation of thiols with EthynylBenziodoXolone (EBX) reagents is a fast and chemoselective method for the synthesis of thioalkynes. Combined experimental and computational studies are reported, which led to the identification of a new mechanism for this reaction, proceeding via an initial sulfur–iodine interaction followed by β-addition, α-elimination, and a 1,2-shift. Depending on the substituent on the alkyne, this mechanism can be favored over the previously disclosed concerted α-addition pathway.
A new band-notched printed monopole antenna for UWB applications

An ultra-wideband (UWB) U type monopole antenna fed by a coplanar waveguide (CPW) with band-notch characteristic is proposed. Printed on a 0.8 mm thick FR4 substrate with relative permittivity of 4.4, it has low profile and very compact size (14.48 mm times 28.74 mm), only around 0.14 lambda times 0.28 lambda in electrical length (lambda is the wavelength of lower frequency 2.95 GHz). It provides an wide impedance bandwidth ranging from 2.95 GHz to about 12.65 GHz (124.4%), and presents a notched band from 5.13 to 5.9 GHz for VSWR- 3, which covers the wireless local area network (WLAN) band. The time-domain behaviors are discussed and the group delay is given. The proposed antenna has a compact size, ultra wide bandwidth, good radiation characteristics, and good time-domain behaviors to satisfy the requirements of the current and future wireless communications systems. Details of the proposed ultra-wideband design are described and parametric study is presented.
ZCS Redux

Learning classifier systems traditionally use genetic algorithms to facilitate rule discovery, where rule fitness is payoff based. Current research has shifted to the use of accuracy-based fitness. This paper re-examines the use of a particular payoff-based learning classifier systemZCS. By using simple difference equation models of ZCS, we show that this system is capable of optimal performance subject to appropriate parameter settings. This is demonstrated for both single- and multistep tasks. Optimal performance of ZCS in well-known, multistep maze tasks is then presented to support the findings from the models.
Throughput capacity in mobile ad-hoc networks with correlated mobility and f-cast relay

The two hop relay algorithms with redundancy are attractive for mobile ad hoc networks (MANET) since they are simple and efficient. In this paper, we extend the analysis of the f-cast two-hop relay algorithm under i.i. d. mobility model to the case of corrected nodes movements, where the source node is allowed to send up to f copies of a packet and the clustered nodes move uniformly across the network. We first provide an effective scheduling-routing algorithm for packet relay inter- and intra-cluster and then explore the scaling laws of throughput capacity of the considered network. This result helps us to study the impact of both the packet redundancy and correlated node movement, and guide us to find the maximum possible throughput capacity through a proper setting of redundancy f.
Evaluation of home care treatment for schizophrenic patients

ABSTRACT – Twenty‐seven patients diagnosed as schizophrenics suffering their first episode of illness and who had not received any prior medical treatment for the present illness, have been treated in their own homes. The treatment was carried out by a visiting nurse, trained in follow‐up assessment and counselling. The outcome of this group was compared with a similar group of 27 patients who underwent initial mental hospital admission and subsequent outpatient follow‐up. Both groups were followed up for 6 months. The results reveal that the home treatment through a visiting nurse gives a better clinical outcome, better social functioning of the patient and greatly reduces the burden on the patients' families. This treatment modality is also more economical.
A novel fingerprint singular point detection algorithm

In this paper, a novel approach for detection of singular points, the core and delta points, in fingerprint images is proposed. There have been many approaches introduced in the design of feature extraction. Based on orientation field, Firstly, we divide it into blocks to compute the Poincare Index. Then, the blocks which may have singularities are detected in the block images. Experiment show the present algorithm is robust than the traditional method on poor quality images.
Performance Degradation of Integrated Optical Modulators Due to Electrical Crosstalk

In this paper, we investigate electrical crosstalk in integrated Mach-Zehnder modulator arrays based on n-doped InP substrate and show that it can be the cause for transmitter performance degradations. In particular, a common ground return path between adjacent modulators can cause high coupling noise up to -20 dB which leads to system power penalties of more than 10 dB at 10 Gb/s OOK modulation. Furthermore, we demonstrate that electrical crosstalk is significantly reduced in the absence of the shared ground and that it varies with modulator separation distance. Experimental results are shown that indicate a crosstalk tolerance of -40 dB for 1 dB power penalty at 10 Gb/s.
Graph Representation of the Syntactic Structure of the Lithuanian Sentence

The paper offers a new way of presenting the structure of a sentence. None of the two widely known methods of representation the syntactic structure of a sentence can be of any avail when applied to the Lithuanian language. Neither the tree, based on the phrase structure principle, nor the tree, suggested by the dependency grammar, do reflect all the syntactic information, which a Lithuanian sentence contains. The paper points out the differences between the Lithuanian language and other languages as well as presents the reasons why a Lithuanian sentence should be represented by a graph. The paper presents a generalized structure of a simple sentence in the Lithuanian language, namely, such a structure, which would embrace all the possible instances of a Lithuanian simple sentence. Every sentence of the text would have to activate only one path in the generalized structure.
On the correctness of IBGP configuration

The Border Gateway Protocol (BGP) has two distinct modes of operation. External BGP (EBGP) exchanges reachability information between autonomous systems, while Internal BGP (IBGP) exchanges external reachability information within an autonomous system. We study several routing anomalies that are unique to IBGP because, unlike EBGP, forwarding paths and signaling paths are not always symmetric. In particular, we focus on anomalies that can cause the protocol to diverge, and those that can cause a router's chosen forwarding path to an egress point to be deflected by another router on that path. Deflections can greatly complicate the debugging of routing problems, and in the worst case multiple deflections can combine to form persistent forwarding loops. We define a correct IBGP configuration to be one that is anomaly free for every possible set of routes sent by neighboring autonomous systems. We show that determination of IBGP configuration correctness is NP-hard. However, we give simple sufficient conditions on network configurations that guarantee correctness.
β‐Band correlates of the fMRI BOLD response

Oscillatory activity in the β‐band (15–30 Hz) has been studied in detail in the sensorimotor cortex. It has been postulated that β‐activity acts as a localized gating of cortical activity. Here, the induced oscillatory response in the β‐band is measured by magnetoencephalography, and the hemodynamic response is measured by fMRI. We assess the linearity of the responses to stimuli of varying duration in the primary motor cortex and to a sinusoidal drifting grating of varying contrast amplitude and drift frequency in the visual cortex. In this way, we explore the nature of β‐oscillations and their relationship with hemodynamic effects. Excellent spatial colocalization of BOLD and β‐activity in both central and lateral (MT) visual areas and sensorimotor areas suggests that the two are intimately related. In contrast to the BOLD response, the level of β‐desynchronization is not modulated by stimulus contrast or by stimulus duration, consistent with a gating role. The amplitude of β‐desynchronization in the central visual area is however modulated by drift frequency, and this seems to parallel the modulation in BOLD amplitude at the same location.

Dual-Space Skin-Color Cue Based Face Detection for Eye Location

A eye location algorithm for color images was proposed based on face detection. Combination of skin-color segmentation based on both YCbCr color space and HSV color space was used for the face detection. Morphological operations were used for further processing of the skin-like color regions. The greylevel information and the geometry feature were used to determine the face boundaries. Greylevel integral and gradient integral projections were used for the eye location. The experiments were implemented on both single face images and video sequences respectively. The results demonstrated that our face detection approach was better than those ones solely based on either the YCbCr space or the HSV space and the eye location algorithm was very robust.
Obstacle detection and safeguarding for a high-speed autonomous hydraulic excavator

Hydraulic excavators are large, powerful machines which are often operated in high-production settings. Successful automation of excavators for mass excavation tasks require safeguarding algorithms which do not negatively impact productivity. We present a two-level sensor-based safeguarding approach which utilizes obstacle detection to prevent collisions and motion detection to halt operation when unanticipated vehicles or people approach the excavator.
Subversion over OpenNetInf and CCNx

We describe experiences and insights from adapting the Subversion version control system to use the network service of two information-centric networking (ICN) prototypes: OpenNetInf and CCNx. The evaluation is done using a local collaboration scenario, common in our own project work where a group of people meet and share documents through a Subversion repository. The measurements show a performance benefit already with two clients in some of the studied scenarios, despite being done on un-optimised research prototypes. The conclusion is that ICN clearly is beneficial also for non mass-distribution applications. It was straightforward to adapt Subversion to fetch updated files from the repository using the ICN network service. The adaptation however neglected access control which will need a different approach in ICN than an authenticated SSL tunnel. Another insight from the experiments is that care needs to be taken when implementing the heavy ICN hash and signature calculations. In the prototypes, these are done serially, but we see an opportunity for parallelisation, making use of current multi-core processors.
A Backward-Recursive PCE-Based Computation (BRPC) Procedure to Compute Shortest Constrained Inter-Domain Traffic Engineering Label Switched Paths

The ability to compute shortest constrained Traffic Engineering (TE) Label Switched Paths (LSPs) in Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks across multiple domains (where a domain is referred to as a collection of network elements within a common sphere of address management or path computational responsibility such as IGP areas and Autonomous Systems) has been identified as a key requirement . This document specifies a procedure relying on the use of multiple Path Computation Elements (PCEs) in order to compute such inter-domain shortest constrained paths along a determined sequence of domains, using a backward recursive path computation technique while preserving confidentiality across domains, which is sometimes required when domains are managed by different Service Providers.
The Contribution of Foreign Direct Investment to China's Export Performance: Evidence from Disaggregated Sectors

There has been a long debate in the theoretical and empirical economic circles on how host country's exports respond to inward foreign direct investment (FDI). This paper examines whether FDI stimulates export performance of the recipient countries using the case of China. It contributes to the literature by investigating the relationship of FDI and export performance using disaggregated manufacturing sectors from 1995 to 2005. The empirical results suggest that FDI flows into China have statistically significant and positive effects on its exports and it exhibits differences across sectors.

The Impact of Cell Phone Use on the Intensity and Liking of a Bout of Treadmill Exercise

This study used a within-subjects design to assess the effect of three common cellular telephone (cell phone) functions (texting, talking, listening to music) on planned exercise. Forty-four young adults (n = 33 females, 21.8 ± 1.3 years) each participated in four, separate, 30-minute exercise conditions on a treadmill in a random order. During each condition, the treadmill speed display was covered and grade was fixed at zero. However, participants were able to alter treadmill speed as desired. Throughout the texting and talking conditions, research personnel used a pre-determined script to simulate cell phone conversations. During the music condition, participants used their cell phone to listen to music of their choice. Finally, participants completed a control condition with no cell phone access. For each condition, average treadmill speed, heart rate and liking (via visual analog scale) were assessed. Treadmill speed (3.4 ± 1.3 miles∙hour-1), heart rate (122.3 ± 24.3 beats∙min-1) and liking (7.5 ± 1.5 cm) in the music condition were significantly (p ≤ 0.014) greater than all other conditions. Treadmill speed in the control condition (3.1 ± 1.2 miles∙hour-1) was significantly (p = 0.04) greater than both texting and talking (2.8 ± 1.1 miles∙hour-1 each). Heart rate during the control condition (115.4 ± 22.8 beats∙min-1) was significantly (p = 0.04) greater than texting (109.9 ± 16.4 beats∙min-1) but not talking (112.6 ± 16.1 beats∙min-1). Finally, liking during the talking condition (5.4 ± 2.2 cm) was greater (p = 0.05) than the control (4.3 ± 2.2 cm) but not the texting (5.1 ± 2.2 cm) conditions. In conclusion, using a cell phone for listening to music can increase the intensity (speed and heart rate) and liking of a bout of treadmill exercise. However, other common cell phone uses (texting and talking) can interfere with treadmill exercise and reduce intensity.
Bidirectional Worst Subchannel Avoiding Versus Best Subchannel Seeking Subcarrier-Allocation in Downlink OFDMA Systems

In this paper, we design and investigate two subcarrier-allocation algorithms for downlink orthogonal frequency-division multiple-access (OFDMA) systems. One is designed to avoid assigning users, by as many as possible, worst subchannels, which is referred to as the bidirectional worst subchannel avoiding (BWSA) algorithm. The other one is called the best subchannel seeking (BSS) algorithm, which aims at assigning users the best possible subchannels. We study and compare the error rate, spectrum efficiency, and the complexity of the two algorithms. We also compare them with some existing subcarrier-allocation algorithms. Our studies show that both the BWSA and BSS algorithms belong to the class of low-complexity subcarrier-allocation algorithms. In general, they outperform all the other considered suboptimal algorithms in terms of both error performance and spectrum efficiency. When operated in relatively large OFDMA systems, we find that both the error performance and the spectrum efficiency attainable by the BWSA and BSS algorithms are close to those achieved by the Hungarian algorithm of high complexity.
Antimalarial activity of Aspilia pruliseta, a medicinal plant from Uganda.

Aspilia pruliseta Schweinf. (Asteraceae) is a medicinal plant indigenous to Uganda and the neighboring countries of East Africa. It has been used extensively by the rural population for the treatment of fevers and malaria. During the antimalarial evaluation of this plant, four nontoxic diterpenes were isolated that possessed moderate activity against chloroquine-sensitive (D6) and chloroquine-resistant (W2) clones of Plasmodium falciparum, with IC(50) values ranging from 14 to 23 µM. These moderately active compounds included the previously undescribed diterpene, ENT-15 β-senecioyloxy-16,17-epoxy-kauran-18-oic acid that demonstrated an IC(50) value of 23.4 µM against clone D6, but was devoid of activity against clone W2. Four additional diterpenes were obtained from the aerial parts of A. pruliseta, but these known compounds were essentially inactive. The moderate activities of select diterpenes of A. pruliseta could account collectively for the historical and enduring use of this plant in traditional African medicine.
True Path Rule Hierarchical Ensembles for Genome-Wide Gene Function Prediction

Gene function prediction is a complex computational problem, characterized by several items: the number of functional classes is large, and a gene may belong to multiple classes; functional classes are structured according to a hierarchy; classes are usually unbalanced, with more negative than positive examples; class labels can be uncertain and the annotations largely incomplete; to improve the predictions, multiple sources of data need to be properly integrated. In this contribution, we focus on the first three items, and, in particular, on the development of a new method for the hierarchical genome-wide and ontology-wide gene function prediction. The proposed algorithm is inspired by the “true path rule” (TPR) that governs both the Gene Ontology and FunCat taxonomies. According to this rule, the proposed TPR ensemble method is characterized by a two-way asymmetric flow of information that traverses the graph-structured ensemble: positive predictions for a node influence in a recursive way its ancestors, while negative predictions influence its offsprings. Cross-validated results with the model organism S. Crevisiae, using seven different sources of biomolecular data, and a theoretical analysis of the the TPR algorithm show the effectiveness and the drawbacks of the proposed approach.
Integrated simulation platform for indoor quadrotor applications

In this paper, an integrated simulation platform is developed for indoor quadrotor applications. The simulation platform mainly consists of two subsystems, the controller subsystem; the other subsystem is an indoor interactive environment. The two integrated subsystems can be highly deployed in quadrotor systems development cycle and validation of different algorithms for indoor navigation. Moreover, the simulation platform has visualization capability and tuning flexibility. These features provide the necessary ability to implement and inspect the developed algorithm in different scenario conditions before implementing them for indoor applications.
On Defect Generation and the Appearance of Injection-Moulded Polymers

This thesis addresses the generation of some important manufacturing defects associated with intrinsic limitations of the injection moulding process. These include bulk-surface structural discontinuities, particularly air traps and welds, bulk-surface compositional inhomogeneities and gloss and colour variations. These defects can limit the performance of the mouldings during service and they can affect their appearance quality. A novel modelling approach (the distance model) has been used to simulate the advancing flow front during mould filling and to predict the location of welds and air traps in polystyrene mouldings. The simulations using the distance model indicated that the movement of the advancing flow front and the potential location of welds and air traps could be predicted with good accuracy. The distance model was also found to be particularly useful for showing the repositioning of welds by changing the wall thickness and gating scheme for a relatively simple mould cavity with different wall thicknesses and a central core. The molecular composition at the surface and in the bulk of these mouldings was studied using time-of-flight secondary ion mass spectroscopy (TOF-SIMS). The results of the TOF-SIMS analysis indicated not only the segregation of additives (paraffin waxes) at the surface of the mouldings during processing but also that segregation of additives at the butting-weld interface for polystyrene is not the main cause of the structural weakness of these defects. A relatively new process methodology has then been applied to study the effects of processing on the appearance characteristics (gloss, colour and surface topography) of mouldings made of different pigmented polypropylenes. The effects of mould texture and pigment content have also been investigated. Differences in visual appearance at the surface of mouldings were associated with the degree of replication of the mould surface topography. The gloss and colour measurements indicated, for example, that the gloss of polypropylene can change significantly during processing and that the filling rate and the topography of the mould surface play a significant role. Correlations were also observed between the colour coordinates and the gloss. Thermal ageing effects and processing effects on the tensile and impact properties and on the gloss and surface topography are also discussed.
Analysis of Microbial Community in Vermifiltration by PCR-SSCP Method

Single-strand conformation polymorphism (SSCP) method was performed to investigate the microbial community in vermifiltration. Vermifiltration was a newly ecological and high efficient process to treat sewage and sludge synchronously. The experimental results indicated that PCR-SSCP can more truly reflect the existing system of micro-organisms groups. Bacillus, the dominant populations, in the vermifiltration with a percentage of 40% is an antagonistic and functional bacterium, and crucial to the treatment efficacy of vermifiltration. Additionally, the positive correlation between earthworm's density and Shannon-wiener index, and the organics removal were existed. Consequently, it can be concluded that the introduction of earthworm was beneficial to the improvement of the bacteria community structure and the removal of the organic pollutants.
